A leveler 100 according to an embodiment of the present invention is described below with reference to fig. 1-6.

the leveler 100 according to the embodiment of the present invention, as shown in fig. 1-5, includes: the device comprises a vehicle body 1, a running device 2, a leveling device 3 and a pose adjusting device 4. The running gear 2 is provided on the vehicle body 1, and the leveling device 3 has a work surface 31 for leveling a surface to be worked. The pose adjusting device 4 is connected between the vehicle body 1 and the leveling device 3, the pose adjusting device 4 is used for driving the leveling device 3 to be switchable between a working state and a narrowing state, the working surface 31 of the leveling device 3 faces the surface to be constructed in the working state, the transverse size of the leveling device 3 in the narrowing state is smaller than that in the working state, and the transverse size of the leveling device 3 is the size of the leveling device 3 in the direction perpendicular to the height direction and the running direction of the leveling machine 100.

It can be understood that, as shown in fig. 1 to 3, before the leveling machine 100 enters the construction zone, the attitude adjusting device 4 can drive the leveling devices 3 to switch to the narrowing state so that the lateral dimension of the leveling devices 3 is smaller than that of the working state, so that the volume of the leveling machine 100 can be reduced and the safety of the leveling machine 100 on the road can be improved. When the leveler 100 enters the construction zone, if the inlet of the construction zone is narrow, such as when a small door is installed, the leveling device 3 is in a narrowed state, and the transverse dimension thereof is small, which is advantageous for the leveler 100 to pass through quickly, and reduces the situation that the leveler 100 is difficult to perform the construction zone due to the large transverse dimension of the leveling device 3. As shown in fig. 5, after the leveling machine 100 is operated in the construction area, the pose adjusting device 4 can drive the leveling device 3 to switch from the narrowing state to the working state, and the traveling device 2 drives the vehicle body 1 to move on the surface to be constructed, so that the leveling operation can be performed by the leveling device 3 with the working surface 31 facing the surface to be constructed. After the leveling work of the leveler 100 is completed, the pose adjustment device 4 can drive the leveling device 3 to switch from the working state to the narrowing state to quickly leave the construction zone.

according to the leveling machine 100 of the embodiment of the invention, the pose adjusting device 4 is arranged to drive the leveling device 3 to be switchable between the working state and the narrowing state, so that the leveling machine 100 can be in the narrowing state to reduce the transverse size of the leveling device 3 when the leveling machine 100 runs on the road or enters a construction area with a narrow entrance, the leveling machine 100 can rapidly pass through the entrance of the construction area, the driving safety is improved, and the trafficability of the leveling machine 100 is improved.

in some embodiments, screed 3 is vertically disposed in a narrowed state, as shown in fig. 1. It will be appreciated that when the screed 3 is vertically disposed, the transverse dimension of the screed 3 is small, so that the screed 3 may occupy a small area when in the narrowed state.

in some embodiments, as shown in fig. 3 and 4, the posture adjustment device 4 includes: an elevating mechanism 41 and a turning mechanism 42. The lifting mechanism 41 is provided on the vehicle body 1. The swing mechanism 42 is provided on the lifting mechanism 41 to be driven by the lifting mechanism 41 to lift, and the leveling device 3 is connected to the swing mechanism 42 to be driven to rotate by the swing mechanism 42. It is understood that when the attitude adjusting device drives the flattening apparatus 3 to switch from the working state to the narrowing state, first the elevation mechanism 41 drives the turning mechanism 42 to move upward, when the moving distance of the turning mechanism 42 is greater than or equal to half the lateral dimension of the flattening apparatus 3, the elevation mechanism 41 stops driving the turning mechanism 42 to move upward, and then the turning mechanism 42 drives the flattening apparatus 3 to rotate so that the lateral dimension of the flattening apparatus 3 is smaller than the lateral dimension of the working state.

When the attitude adjusting device drives the leveling device 3 to be switched from the narrowing state to the working state, first, the lifting mechanism 41 drives the turning mechanism 42 to move downward, when the moving distance of the turning mechanism 42 is less than or equal to half of the transverse dimension of the leveling device 3, the lifting mechanism 41 stops driving the turning mechanism 42 to move downward, and then the turning mechanism 42 drives the leveling machine 100 to rotate so that the working surface 31 of the leveling device 3 faces the surface to be constructed. Of course, the following switching sequence may also be employed: the turning mechanism 42 first drives the screed 3 to rotate so that the working surface 31 of the screed 3 faces the surface to be worked, and then the elevating device drives the turning mechanism to move downward. The specific handover procedure is not specifically limited herein.

One end of the rotating mechanism 42 is arranged on the lifting mechanism 41, and the other end is connected with the leveling device 3, so that the leveling device 3 can lift along with the rotating mechanism, the layout is compact, and the occupied space is small.

Specifically, as shown in fig. 2 and 3, the lifting mechanism 41 includes: a lifting base 411, a lifting motor 412, a lead screw 413 and a lifting nut (not shown). The elevating base 411 is provided on the vehicle body 1. The elevating motor 412 is provided on the elevating base 411. The lead screw 413 is rotatably provided on the elevating base 411, and the lead screw 413 is connected to the elevating motor 412. The elevating nut is fitted to the lead screw 413, and the turning mechanism 42 is connected to the elevating nut. It can be understood that the lifting base 411 can limit and fix the lifting motor 412, thereby improving the working stability of the lifting motor 412. The lifting base 411 can also limit and support the lead screw 413, so that the rotating stability of the lead screw 413 is improved, and the service life of the lead screw 413 is prolonged. Like this lift motor 412 can drive lead screw 413 and rotate, and lead screw 413 can be with rotary motion transformation to reciprocate simultaneously to change lifting nut position, make rotary motor 423 reciprocate with lifting nut together.

Of course, in other embodiments of the present invention, the lifting mechanism 41 may also adopt other structures, such as a chain transmission mechanism, or a rack-and-pinion mechanism.

in some alternative embodiments, as shown in fig. 2 and 4, the lifting base 411 has a vertically extending installation cavity, the lead screw 413 is vertically disposed in the installation cavity, the lifting motor 412 is connected to an end of the lifting base 411, a vertically extending matching port is disposed on the lifting base 411, the matching port is communicated with the installation cavity, a matching block 424 is disposed on the swing mechanism 42, and the matching block 424 extends into the installation cavity through the matching port. It can be understood that, the installation cavity provides the accommodation space for the lead screw 413 and the matching block 424, so that the lead screw 413 can be vertically arranged in the installation cavity, the matching block 424 can be accommodated in the installation cavity through the matching opening, and meanwhile, the matching block 424 is limited by the matching opening and fixed on the lifting base 411, and the installation stability of the swing mechanism 42 can be improved.

In some alternative embodiments, as shown in fig. 5 and 6, the swing mechanism 42 includes: a rotating base 422 and a rotating motor 423. The rotary base 422 is connected to the elevating mechanism 41. The rotary motor 423 is provided on the rotary base 422, and the leveling device 3 is connected to the rotary motor 423. It can be understood that the rotary base 422 may be used to connect the lifting mechanism 41 and the rotary motor 423, and may support and fix the rotary motor 423 to improve the working stability of the rotary motor 423, so that the rotary motor 423 may stably drive the leveling device 3 to rotate.

specifically, a rotation cavity is formed in the rotation base 422, the rotation mechanism 42 further includes a steering gear set (shown in the figure) disposed in the rotation cavity, the rotation motor 423 is located outside the rotation cavity, a motor shaft of the rotation motor 423 extends into the rotation cavity and is connected to the steering gear set, and an output end of the steering gear set extends out of the rotation cavity and is connected to the leveling device 3. It will be appreciated that, under the drive of the rotary motor 423, the motor shaft will drive the rotary gear set to rotate, thereby driving the leveling device 3 connected to the output end of the steering gear set to rotate.

The swing mechanism 42 has such a driving structure, which not only has a small number of parts and a compact structure, and is beneficial to the simplified design of the leveling machine 100, but also has high stability and more reliable transmission.

In some embodiments, as shown in figures 5 and 6, the flattening device 3 comprises: and the scraping mechanism 5 is arranged on the vehicle body 1, and the scraping mechanism 5 is provided with a scraper 51 for scraping the surface to be constructed. Thus, the screeding plates 51 of the screeding mechanism 5 can screeding the surface to be worked during the running of the leveler 100, so that the leveling effect of the surface to be worked can be improved.

Specifically, as shown in fig. 5 and 6, the flattening device 3 further includes: the vibration mechanism 32, the vibration mechanism 32 is provided on the strickle mechanism 5, and the vibration mechanism 32 has a vibration plate 331 capable of vibrating up and down. It can be understood that the arrangement of the vibration plate 331 can improve the compactness of the surface to be constructed and improve the construction quality of the surface to be constructed. Specifically, the vibration plate 331 provided on the vibration mechanism 32 may vibrate up and down to generate a certain impact force on the surface to be constructed, so that the surface to be constructed is vibrated up and down by the impact force to become more dense and flat, thereby improving the flatness and quality of the surface to be constructed.

Optionally, as shown in fig. 5 and fig. 6, a vibration motor 332 is disposed on the vibration plate 331, and after the vibration motor 332 vibrates, the vibration plate 331 can be driven to vibrate fast and at high frequency relative to the surface to be constructed, so that the vibration effect is good.

Alternatively, as shown in fig. 5 and 6, a plurality of vibration motors 332 are spaced on the vibration plate 331 to make the vibration plate 331 vibrate uniformly, so as to improve the vibration leveling effect of the vibration leveling mechanism.

Alternatively, as shown in fig. 5 and 6, a rotation motor 333 is provided on the vibration plate 331, and the rotation motor 333 may drive the vibration plate 331 to switch between the first position and the second position. In the first position, vibration plate 331 is positioned on the horizontal side of scraper 51 and faces the working surface, and in the second position, vibration plate 331 is positioned above scraper 51. Specifically, the vibration plate 331 has a first position and a second position, and the vibration plate 331 can reach the second position from the first position or reach the first position from the second position to realize position adjustment, so that the leveling operation under different working conditions is adapted.

In the leveling device 3, as shown in fig. 6, the vibration plate 331 is in the first position in the initial state, and the vibration plate 331 is located at the front side of the squeegee 51, and the surface to be worked needs to be subjected to two steps of scraping and leveling during the working operation. However, when an obstacle such as a footing is encountered, the leveling machine 100 cannot move forward, and the area covered by the vibration plate 331 cannot be leveled. In the present apparatus, as shown in fig. 5, when an obstacle such as a corner is encountered, the rotation motor 333 is activated to rotate the vibration plate 331, and the vibration plate 331 rotates from the first position to the second position, and at this time, the vibration plate 331 is located above the scraper 51, so that the leveling machine 100 can continue to move forward, and the area originally covered by the vibration plate 331 can be leveled by the scraper 51. As shown in fig. 6, after the operation of the scraper 51 is finished, the leveling machine 100 moves backward, the vibration plate 331 rotates from the second position to the first position, and the vibration of the vibration plate 331 can achieve the leveling process for the above-mentioned area, thereby improving the leveling effect for the construction surface.

In some embodiments, the planer 100 further comprises: detection means (not shown) for detecting an external environment to control the pose adjustment means 4. The detection device can improve the automation degree of the leveling machine 100, and is beneficial to improving the leveling construction efficiency.

optionally, the detection device includes a control device (not shown) and a camera or a laser receiver connected to the control device. In this way, the camera or the laser receiver receives the signal and transmits the signal to the control device, so that the pose adjusting device 4 can be controlled and the automation of the leveling machine 100 can be improved.
