Technical Field

The invention belongs to the field of machinery, and particularly relates to a crop straw cutting device.

Background

When the crop straws are used, the crop straws are generally required to be cut into small pieces in advance. However, the existing cutting structure is generally provided with only one feeding hole and one discharging hole, and then a cutter is arranged on one side to cut the straw. However, when the cutting machine with the structure is used for cutting straws, only one side of a rotating shaft connected with the cutter is stressed, so that the power imbalance is easily caused, the shaking of the device is easily caused, and the noise is high. In addition, the long-term use still makes the motor shaft appear bending deformation etc. still easily, reduces its life.

The two cutting cylinders are arranged, so that the overall force balance of the cutter during cutting is ensured, the vibration and noise of the device are effectively reduced, the service life of the motor is prolonged, and in addition, the cutting effect is ensured by arranging the limiting feeding structure.

In order to achieve the technical effects, the technical scheme of the invention is as follows:

a crop straw cutting device comprises a base, wherein two feeding cylinders are mounted on the base, a rotary power device is mounted between the feeding cylinders, and a plurality of cutters are symmetrically mounted on a rotating shaft of the rotary power device; when the cutter rotates, the feeding cylinder moving from bottom to top is provided with a limiting feeding structure; the rear end of the feeding cylinder is provided with a feeding mechanism.

In a further improvement, the feeding mechanism comprises two oppositely arranged clamping feeding rollers.

In a further improvement, the clamping feed roller is connected with a driving wheel, and the driving wheels are in transmission connection through a transmission belt; one of the driving wheels is connected with a motor.

In a further improvement, a feeding conveyor belt is arranged at the rear end of the clamping feeding roller.

In a further improvement, the rear ends of the inner sides of the two feeding cylinders are fixedly provided with a material guide plate which is obliquely arranged.

In a further improvement, the limiting feeding structure comprises a pressing plate, and the pressing plate is connected with a sliding rod which is arranged in a sliding manner with the feeding cylinder; an elastic structure is arranged between the pressure plate and the feeding cylinder.

Detailed Description

The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

Example 1

The crop straw cutting device shown in fig. 1-3 comprises a base 1, two feeding cylinders 2 are mounted on the base 1, a rotary power device 15 is mounted between the feeding cylinders 2, and two cutters 16 are symmetrically mounted on a rotating shaft 3 of the rotary power device 15. The rotary power device 15 is a motor.

In this embodiment, set up two feeding section of thick bamboo 2 feeding respectively, and set up the pivot between two feeding section of thick bamboos 2, when the cutter rotated the cutting under the motor drove like this, two cutters cut simultaneously, and the power size that receives is approximate, opposite direction to make the whole atress of pivot reach the balance, thereby be difficult for appearing vibrations and the condition that the pivot stress leads to the bending, the machine noise that produces when having reduced the cutting.

Example 2

On the basis of the embodiment 1, in order to facilitate automatic feeding, the rear end of the feeding cylinder 2 is provided with a feeding mechanism 5. The feed mechanism 5 comprises two oppositely arranged pinch feed rollers 6. The rear end of the clamping feed roller 6 is provided with a feeding conveyor belt 9. The clamping feed roller 6 is connected with a driving wheel 7, and the driving wheels 7 are in transmission connection through a transmission belt 8; one of the transmission wheels 7 is connected with a motor.

The rear ends of the inner sides of the two feeding cylinders 2 are fixed with a guide plate 10 which is obliquely arranged.

This is fed by the feed conveyor 9 and then by the pinch feed rollers 6. The material is clamped tightly, and the pushing force to the material is guaranteed.

Example 3

On the basis of the embodiment 1, the straw is cut off in a scissor shape formed between the cutter and the feeding cylinder 2 during cutting, and the feeding cylinder 2 through which the cutter moves from bottom to top has a gap with the straw due to the fact that the top of the feeding cylinder 2 is lower in cutting efficiency and the straw is easy to be cut off, so that the limiting feeding structure 4 is added, the limiting feeding structure 4 comprises a pressing plate 11, and the pressing plate 11 is connected with a sliding rod 12 which is arranged in a sliding manner with the feeding cylinder 2; between the pressure plate 11 and the feed cylinder 2, a resilient structure 17, such as a spring, is mounted.

A limiting block 13 is fixed at the top of the sliding rod 12. The rear end of the pressing plate 11 is tilted to form an arc material guiding part 14.

Thus, when the material enters the feeding cylinder 2, the pressing plate 11 presses the material and cooperates with the cutter to form shearing to cut the material, and the arc-shaped material guiding part 14 facilitates the material to enter. The bottom of the limiting block 13 can be connected with a plurality of rotating shafts in a shaft mode so as to reduce friction on materials.

The above description is only one specific guiding embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modification of the present invention using this concept shall fall within the scope of the invention.
