The arc-shaped plate 10 can enable the first striker plate 11 at the far end of the material extruding plate 5 in the pivoting process to clean the inner wall of the back plate 203.

A second material baffle plate (not shown in the figure) acting on the inner side surface of the material baffle leakage plate 4 is arranged on one side of the bottom plate 201 close to the front plate 202. The second material blocking plate is used for cleaning the inner wall of the material blocking leakage plate 4 which moves up and down.

The working principle of the device is as follows:

the first step is as follows: adjusting the discharge capacity of the hopper:

the hopper 2 is pushed to a discharging place, the amplitude adjusting assembly 7 is adjusted, namely the crank 704 is rotated to rotate the lead screw 702, the lead screw nut block 703 sleeved on the lead screw 702 moves horizontally along the limit guide groove 701, the mounting seat 705 mounted on the lead screw nut block 703 also moves along with the lead screw nut block 703, so that the supporting slide block 610 mounted on the second rotating shaft 706 moves horizontally along the fulcrum guide groove 609 on the second connecting rod 602 to change the position of the rotating fulcrum of the second connecting rod 602, and the position of the graduated scale 13 aligned with the supporting slide block 610 is the discharging amount;

when the supporting slide block 610 moves and adjusts to the right gradually, the rotating arm of the second connecting rod 602 on the left side is lengthened, so that the material blocking and leaking plate 4 on the first connecting rod 601 hinged with the second connecting rod 602 has a larger lifting amplitude (more discharging amount);

step two, unloading:

the stepping motor 606 is started, the motor 606 drives the rotating wheel 604 with the first rotating shaft 605 to rotate, the rotating wheel 604 is equivalent to a cam in the rotating process due to the eccentric arrangement of the first rotating shaft 605, and the shifting lever 607 arranged at the hinge shaft of the second connecting rod 602 and the third connecting rod 603 makes a leaning motion along with the rotating wheel 604 in the guide ring groove 608 of the rotating wheel 604.

Because the shifting lever 607 is sleeved at the lowest end of the guide ring groove 608 on the rotating wheel 604, when the shifting lever 607 moves to the highest point, the upper end of the rotating wheel 604 moves to the highest point, the top rod 802 supported by the top end of the rotating wheel 604 moves to the highest point, the upper end of the top rod 802 jacks up the lower surface of the material extruding plate 5, and the concrete on the upper portion of the material extruding plate forms extrusion towards one side of the discharge port 205 of the front plate 202, which is beneficial to accelerating the blanking progress;

meanwhile, as the shift lever 607 moves to the highest point, that is, the right end of the second connecting rod 602 rotates to the highest point with the supporting slider 610 as a fulcrum, the left end of the second connecting rod 602 rotates to the lowest point with the supporting slider 610 as a fulcrum, the upper end of the material blocking leakage plate 4 hinged with the first connecting rod 601 and linked with the left end of the second connecting rod 602 descends to the lowest point of the discharging amount, so that the discharging amount is the largest, the side material extruding plate 5 is just met to give the largest lateral pressure to the concrete on the side material blocking leakage plate, the cement is extruded out from the upper part of the material blocking leakage plate 4 and flows down along the material guiding plate 9;

after the rotating wheel 604 continues to rotate 180 degrees, the shift lever 607 moves to the lowest point, the upper end of the rotating wheel 604 descends to the lowest point, and the top rod 802 where the baffle ring 708 is located is pulled down under the action of the elastic force of the compression spring 709, that is, the material extruding plate 5 connected with the top rod 802 is also pulled down. So reciprocal, until under the lifting amplitude of this material stopping and leaking board 4, no longer have the concrete to flow out from hopper 2, accomplish once the process of unloading.

Before discharging, the concrete can be shaken by the device of the invention in advance in order to improve the fluidity of the concrete because some concrete generates slight adhesion phenomenon. The implementation mode is as follows: rotating the rotating crank 704. The supporting sliding block 610 slides to the rightmost side of the fulcrum guide groove 609 in fig. 3, at this time, the stepping motor 606 is started, the material blocking and leaking plate 4 cannot descend, and the fluctuant material extruding plate 5 can shake the concrete on the material blocking and leaking plate, so that the concrete has stronger fluidity.

And then, adjusting the amplitude adjusting assembly 7 again according to the subsequent discharging amount to perform subsequent discharging work. Compared with the existing trolley device, the multi-time quantitative discharging device can realize quantitative discharging in a grading mode, manual discharging is achieved in a mechanical mode, the trolley does not need to be turned over manually in the discharging process, and labor intensity of workers is reduced.

The material extruding plate 5 which is up and down fluctuated and pivoted forms the stirring of the concrete above the material extruding plate, so that the initial setting phenomenon in the discharging process is greatly reduced, no stirring device is required to be additionally arranged, and the material blocking and leaking plate 4 and the material extruding plate 5 are arranged in a linkage manner, so that the mechanism is simplified, and the device is simplified;

in the pivoting process of the material extruding plate 5, the device can scrape and clean the local side wall and the corner part of the hopper 2 by using the first material blocking plate 11 and the second material blocking plate on the side edges, so that the problem that concrete is accumulated at the corner and is difficult to clean is avoided, and the material blocking leakage plate 4 at the end with relatively small motion amplitude of the material extruding plate 5 can drive the concrete on the inner side wall of the material blocking leakage plate 4 to fluctuate up and down in the lifting process, so that the problem that the concrete is accumulated in the area to form a cleaning dead angle which is difficult to scrape is avoided.

To remaining concrete in the hopper 2, can incline the device by the manual work and empty it, clear up completely, improved clean efficiency.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
