Description

Technical Field

[0001] The utility model relates to the technical field of straw crushing, in particular to a straw crushing machine which is convenient to maintain. Background Art

[0002] With the development of agricultural mechanization, a large amount of straw waste is usually left after harvesting crops such as wheat, rice, and corn. When dealing with these straw wastes, the traditional way is to burn them directly. Burning straw will cause atmospheric pollution, so this treatment method has been eliminated. The existing mainstream straw treatment method is to crush and recycle it through a straw crusher and develop it into renewable energy or renewable materials. This not only protects the environment well, but also realizes the recycling of straw resources, achieving the effect of turning waste into treasure.

[0003] In the prior art, after a straw crusher has been used for a long time, in order to avoid clogging of the sieve holes and affecting the subsequent screening effect, the internal sieve plate needs to be removed and cleaned. The cleaned sieve plate is reinstalled in the crusher, which is time-consuming and labor-intensive to clean and maintain, and the sieve plate cannot be maintained quickly. How to invent a straw crusher that is easy to maintain to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a straw crusher that is easy to maintain, aiming to improve the problem that the straw crusher cannot quickly maintain the screen plate.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a straw crusher which is convenient for maintenance, comprising a machine body and a screen plate arranged on the machine body, a first motor is installed on an outer wall of one side of the machine body, a symmetrical crushing roller is installed on the inner wall of the upper end of the machine body, one end of the crushing roller is fixedly connected with a toothed disc meshing with each other, a second motor is installed on an outer wall of one side of the machine body near the lower part of the crushing roller, a feeding port is provided on the inner wall of the machine body near the lower part, a mounting plate is fixedly connected to the inner wall of one side of the machine body, two symmetrical supporting springs are fixedly connected to the upper end of the machine body, an outer wall of one side of the machine body is rotatably connected with an adjusting shaft, a plurality of gear teeth are provided on the outer wall of the adjusting shaft, and an adjusting gear is fixedly connected to the outer wall of the adjusting shaft near the upper part of the gear teeth;

[0007] A plurality of sieve holes are provided on the surface of the sieve plate, and fixed sleeves rotatably connected to the inner wall of the machine body are fixedly connected at both ends of one side of the sieve plate, and an outer tooth ring meshing with the gear teeth is fixedly connected to the outer wall of one of the fixed sleeves, and a driving groove is provided on one side of the sieve plate, and a reciprocating screw rotatably connected to the inner wall of the fixed sleeve is installed on the inner wall of the driving groove, and one end of the reciprocating screw is fixedly connected to a driving gear meshing with the adjusting gear.

[0009] Preferably, both ends of the reciprocating screw rod are rotatably connected to the inner wall of the driving groove, and one end of the reciprocating screw rod is fixedly connected to the output end of the second motor.

[0010] By adopting the above technical solution, when the sieve holes on the sieve plate are blocked, the second motor is started to make the reciprocating screw drive the adjusting shaft at one end to rotate, and the gear teeth on the outside of the adjusting shaft cooperate with the outer gear ring at one end of the fixed sleeve to rotate one end of the sieve plate upward by a certain angle. When the gear teeth and the outer gear ring are out of contact, the sieve plate falls on the supporting spring under the action of gravity and vibrates, thereby cleaning the debris blocked in the sieve holes.

[0011] Preferably, a slide groove is provided on one side of the sieve plate, a guide rod is fixedly connected to the inner wall of the slide groove, and a brush plate is installed above the sieve plate.

[0012] Preferably, the bristles of the brush plate are flexible filaments that can be bent.

[0013] Preferably, two symmetrical fixing blocks are fixedly connected at both ends, wherein the outer wall of one of the fixing blocks is slidably connected to the inner wall of the slide groove, and the inner wall of one of the fixing blocks is slidably connected to the outer wall of the guide rod.

[0014] Preferably, the outer wall of another of the fixing blocks is slidably connected to the inner wall of the driving groove, and the inner wall of another of the fixing blocks is threadedly connected to the outer wall of the reciprocating screw.

[0015] By adopting the above technical solution, the reciprocating screw rotates to make the fixed block in the driving groove drive the brush plate above to slide. The bristles on the brush plate extend into the sieve holes during the movement, and the debris blocked inside is cleaned during the movement.

[0016] The beneficial effects of the utility model are:

[0017] The reciprocating screw rod cooperates with the adjusting shaft and the fixed sleeve to make the screen plate rotate upward with the fixed sleeve as the axis. At the same time, the gear teeth cooperate with the external gear ring to make the screen plate fall after rotating to a certain height, and make one end of the screen plate fall onto the supporting spring below to make the screen plate vibrate. During the vibration, the debris inside the screen hole is shaken off to clean the screen hole. At the same time, the double-headed screw rod cooperates with the fixed block to make the brush plate drive the brush below to slide back and forth, and extend into the screen hole during the movement so that the bristles slide and poke the debris off, thereby cleaning the debris in the screen hole, so that the screen plate can be maintained simply and quickly.
