Description

Technical Field

[0001] This utility model relates to the field of straw crushing technology, specifically to a crop straw crusher that prevents straw from clogging. Background Technology

[0002] Straw is a general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (usually coarse grains) after the grain is harvested. Straw contains more than half of the products of crop photosynthesis and is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. It is a multi-purpose renewable biological resource and also a kind of roughage. When processing crop straw, a crusher is required.

[0003] Existing crop straw crushers often experience clogging of the mesh by finely chopped straw falling from the top of the filter screen during operation, resulting in straw residue on the filter screen and reduced work efficiency. Therefore, a crop straw crusher designed to prevent straw residue clogging is proposed to solve the aforementioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a crop straw crusher that prevents straw from being stuck and blocked, in order to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a crop straw crusher to prevent straw from being stuck and blocked, including a box, a crushing mechanism on the box, a filter screen plate hinged to the inner wall of the box, and an anti-blocking mechanism and a material dispersing mechanism on the box;

[0006] The crushing mechanism includes: two rotating shafts and a motor. The two rotating shafts are rotatably connected to the inner wall of the housing through bearings. Crushing rollers are fixedly sleeved on the outer walls of the two rotating shafts. The front ends of the two rotating shafts penetrate the housing and extend forward. Gears are fixedly sleeved on the outer walls of the two rotating shafts. The motor is connected to the front of the housing through a mounting bracket. The front end of the rotating shaft on the left side is connected to the output end of the motor.

[0007] The anti-clogging mechanism includes: a support bar, a rotating rod, and two pulleys. The support bar is connected to the inner right wall of the housing. A top rod is slidably connected to the support bar, with its top end near the bottom of the filter plate. A connecting sleeve is fixedly fitted onto the outer wall of the top rod. A spring connects the connecting sleeve to the support bar. A bracket is connected to the outer wall of the top rod. The rotating rod is rotatably connected to the inner front wall of the housing via a bearing. A turntable is connected to the rear end of the rotating rod. A sliding rod is eccentrically connected to the back of the turntable. The front end of the rotating rod penetrates the housing and extends forward. A first pulley is connected to the front end of the rotating rod. The second pulley is connected to the front of the rotating shaft on the right side. At the end, the motor drives the left rotating shaft, and with the help of two meshing gears, the two crushing rollers rotate synchronously relative to each other, efficiently crushing the straw entering the box and improving crushing efficiency. The rotating shaft drives the second pulley to rotate, and the second pulley drives the first pulley to rotate via a belt. The first pulley drives the rotating rod to rotate, and the rotating rod drives the turntable to rotate. The eccentrically connected sliding rod on the turntable pushes the bracket on the top rod, so that the bracket drives the top rod to slide up and down on the support bar and pull the spring. This causes the top rod to intermittently push the filter screen plate, causing the filter screen plate to intermittently swing around the hinge point, causing the straw stuck on the filter screen plate to fall off, avoiding filter screen blockage and improving working efficiency.

[0008] Preferably, the two gears mesh to ensure that the two crushing rollers rotate synchronously relative to each other, so as to stably carry out the straw crushing work, and the second pulley is connected to the first pulley by belt drive.

[0009] Preferably, a discharge port is provided on the right side of the box body, and the right side of the filter plate is inclined downward and extends out to the discharge port, so that the crushed straw retained on the filter plate can be smoothly discharged from the box body through the filter plate, reducing the residue of straw in the box body and improving the discharge efficiency.

[0010] Preferably, the feeding mechanism includes a reciprocating screw and a moving block. The reciprocating screw is rotatably connected to the inner wall of the back of the housing via a bearing. The front end of the reciprocating screw passes through the housing and extends forward. A second gear is connected to the front end of the reciprocating screw, and the second gear meshes with the first gear on the right side. The two threaded grooves of the reciprocating screw are connected to the moving block via a slider. A connecting rod is connected to the left side of the moving block. A plow is connected to the end of the connecting rod away from the moving block and is located above the crushing roller. The rotation of the first gear drives the second gear to rotate, which in turn drives the reciprocating screw to rotate, causing the moving block to move back and forth on the reciprocating screw. This causes the moving block to move the connecting rod and the plow to evenly disperse the straw, preventing the straw from accumulating above the crushing roller and improving the crushing effect.

[0011] Preferably, a groove is provided on the right side of the box body, and the right side of the moving block is slidably connected in the groove, providing a stable sliding track for the moving block, ensuring that the plow and harrow run smoothly during movement, and ensuring the stability of the material unloading effect.

[0012] Preferably, the top of the box is connected to a feeding hopper, and the bottom of the box is connected to a discharge pipe. The feeding hopper facilitates the input of straw into the box, and the discharge pipe facilitates the discharge of the crushed and filtered straw.

[0013] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0014] 1. This crop straw crusher, designed to prevent straw clogging, uses a motor to drive a left-side rotating shaft. Two meshing gears enable synchronous relative rotation of two crushing rollers, efficiently crushing the straw entering the casing and improving crushing efficiency. The rotating shaft drives a second pulley, which in turn drives a first pulley via a belt. This first pulley drives a rotating rod, which in turn drives a turntable. An eccentrically connected sliding rod on the turntable pushes a support on a top rod, causing the support to slide the top rod up and down on a support bar and pull a spring. This intermittently pushes the filter screen plate, causing the filter screen plate to oscillate intermittently around a hinge point, causing the straw stuck on the filter screen to fall off, preventing clogging and improving work efficiency.

[0015] 2. This crop straw crusher prevents straw from accumulating and clogging. Gear 1 rotates, which drives gear 2 to rotate. Gear 2 drives a reciprocating screw to rotate, causing the moving block to move back and forth on the reciprocating screw. This in turn causes the moving block to move the connecting rod and the plow to move and evenly disperse the straw, preventing the straw from accumulating above the crushing roller and improving the crushing effect.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0025] Please see Figure 1-4One embodiment of this utility model is: a crop straw crusher for preventing straw clogging, comprising a housing 1, a crushing mechanism 2 disposed on the housing 1, a filter screen 3 hinged to the inner wall of the housing 1, an anti-clogging mechanism 4 and a material unloading mechanism 5 disposed on the housing 1; the crushing mechanism 2 includes: two rotating shafts 21 and a motor 24, the two rotating shafts 21 being rotatably connected to the inner wall of the housing 1 by bearings, crushing rollers 22 being fixedly sleeved on the outer wall of each of the two rotating shafts 21, the front ends of each of the two rotating shafts 21 penetrating the housing 1 and extending forward, and gears 23 being fixedly sleeved on the outer wall of each of the two rotating shafts 21, and two gears 23 being fixedly sleeved on the outer wall of each of the two rotating shafts 21. The three-phase meshing ensures that the two crushing rollers 22 rotate synchronously relative to each other, stably crushing the straw. The motor 24 is connected to the front of the box 1 via a mounting bracket. The front end of the left rotating shaft 21 is connected to the output end of the motor 24. By starting the motor 24, the left rotating shaft 21 is driven, and with the help of two meshing gears 23, the two crushing rollers 22 rotate synchronously relative to each other, efficiently crushing the straw entering the box 1 and improving the crushing efficiency. The anti-blocking mechanism 4 includes: a support bar 41, a rotating rod 46, and a pulley 410. The support bar 41 is connected to the inner wall of the right side of the box 1, and a top is slidably connected to the support bar 41. The top of the rod 42 is close to the bottom of the filter plate 3. A connecting sleeve 43 is fixedly sleeved on the outer wall of the top rod 42. A spring 44 is connected between the connecting sleeve 43 and the support bar 41. A bracket 45 is connected to the outer wall of the top rod 42. The rotating rod 46 is rotatably connected to the inner wall of the front of the housing 1 through a bearing. A turntable 47 is connected to the rear end of the rotating rod 46. A sliding rod 48 is eccentrically connected to the back of the turntable 47. The front end of the rotating rod 46 passes through the housing 1 and extends forward. A pulley 49 is connected to the front end of the rotating rod 46. A second pulley 410 is connected to the front end of the rotating shaft 21 on the right side. The second pulley 410 and the pulley 49 are connected to each other. The components are connected by a belt drive. The rotating shaft 21 drives the second pulley 410 to rotate, and the second pulley 410 drives the first pulley 49 to rotate via the belt. The first pulley 49 drives the rotating rod 46 to rotate, and the rotating rod 46 drives the turntable 47 to rotate. The eccentrically connected sliding rod 48 on the turntable 47 pushes the bracket 45 on the top rod 42, so that the bracket 45 drives the top rod 42 to slide up and down on the support bar 41 and pull the spring 44. This causes the top rod 42 to intermittently push the filter screen plate 3, causing the filter screen plate 3 to intermittently swing around the hinge point, so that the straw stuck on the filter screen plate 3 falls off, avoiding filter screen blockage and improving work efficiency.

[0026] A discharge port is provided on the right side of the box body 1. The right side of the filter screen plate 3 is inclined downward and extends out to the discharge port, so that the crushed straw retained on the filter screen plate 3 can be smoothly discharged from the box body 1 through the filter screen plate 3, reducing the residue of straw in the box body 1 and improving the discharge efficiency. The top of the box body 1 is connected to the feed hopper 6, and the bottom of the box body 1 is connected to the discharge pipe 7. The feed hopper 6 facilitates the input of straw into the box body 1, and the discharge pipe 7 facilitates the discharge of the crushed and filtered straw.

[0027] Working principle: Straw is placed into the box 1 through the feed hopper 6. The left rotating shaft 21 is driven by the starter motor 24. With the help of two meshing gears 23, the two crushing rollers 22 rotate synchronously and relative to each other, which efficiently crushes the straw entering the box 1. The crushed straw is screened through the filter screen 3. The straw passing through the filter screen 3 is discharged through the discharge pipe 7. The rotating shaft 21 drives the pulley 410 to rotate. The pulley 410 drives the pulley 49 to rotate through the belt. The pulley 49 drives the rotating rod 46 to rotate. The rotating rod 46 drives the turntable 47 to rotate. The eccentrically connected sliding rod 48 on the turntable 47 pushes the bracket 45 on the top rod 42. The bracket 45 drives the top rod 42 to slide up and down on the support bar 41 and pull the spring 44. This causes the top rod 42 to intermittently push the filter screen 3, causing the filter screen 3 to intermittently swing around the hinge point. The straw stuck on the filter screen 3 falls off and is discharged through the discharge port.

[0028] Please see Figure 1-4 Based on the above embodiments, in another embodiment of this utility model, the unloading mechanism 5 includes: a reciprocating screw 51 and a moving block 52. The reciprocating screw 51 is rotatably connected to the inner wall of the back of the housing 1 via bearings. The front end of the reciprocating screw 51 passes through the housing 1 and extends forward. A gear 2 55 is connected to the front end of the reciprocating screw 51, and the gear 2 55 meshes with a gear 1 23 on the right side. The two threaded grooves of the reciprocating screw 51 are connected to the moving block 52 via a slider. A sliding groove is provided on the right side of the housing 1, and the right side of the moving block 52 is slidably connected in the sliding groove, providing stable support for the moving block 52. The sliding track ensures that the plow 54 operates smoothly during movement, guaranteeing the stability of the material distribution effect. A connecting rod 53 is connected to the left side of the moving block 52. The end of the connecting rod 53 away from the moving block 52 is connected to the plow 54 and is located above the crushing roller 22. The rotation of gear 1 23 drives gear 2 55 to rotate, which in turn drives the reciprocating screw 51 to rotate, causing the moving block 52 to move back and forth on the reciprocating screw 51. This, in turn, causes the moving block 52 to move the connecting rod 53 and the plow 54 to evenly distribute the straw, preventing the straw from accumulating above the crushing roller 22 and improving the crushing effect.

[0029] Working principle: The rotation of gear 1 23 drives the rotation of gear 2 55, which in turn drives the rotation of reciprocating screw 51. This causes the moving block 52 to move back and forth on the reciprocating screw 51, which in turn drives the connecting rod 53 and the plow 54 to move and evenly disperse the straw, preventing the straw from accumulating above the crushing roller 22.

[0030] It is worth noting that the motor 24 in the above embodiments is a commonly used device in the prior art. The model and other features can be customized according to actual usage requirements. Furthermore, the power supply interface of the electrical equipment in this utility model is connected to the power supply system through a switch (not shown in the figure) and wires (not shown in the figure) to achieve control over it.
