Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, specifically a barley straw crushing device. Background Technology

[0002] With the large-scale development of global agriculture, the output of agricultural waste such as straw continues to rise. Taking China as an example, the annual output of straw exceeds 900 million tons. Among them, barley straw, due to its high lignin content and dense fiber structure, was traditionally burned directly. Burning straw causes air pollution, so this method has been phased out. The current mainstream straw treatment method is to recycle it and develop it into renewable energy or renewable materials. This not only protects the environment well, but also realizes the recycling and utilization of straw resources, achieving the effect of turning waste into treasure.

[0003] In existing technologies, straw needs to be crushed before recycling. When processing excessively long straw, it is usually necessary for personnel to hold the straw and insert it into the inlet of the crusher for crushing. During the crushing process, personnel need to push the straw gradually to crush it, which not only increases the labor intensity, but also causes a small amount of debris to float out and adhere to the surface of the personnel's clothing. In addition, existing crushers cannot adjust the size of the crushed straw, which means that secondary processing is required when smaller straw particles are needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a barley straw crushing device, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a barley straw crushing device, comprising a box body, a discharge port on the surface of the box body, mounting frames fixedly connected to both sides of the outer wall of the box body, a feeding box fixedly connected to the top of the box body, two first motors fixedly mounted on the surface of the feeding box, a fixing plate fixedly connected to the top of the box body, a second motor fixedly mounted on the top of the fixing plate, a screw fixedly connected to the output end of the second motor, a pusher plate slidably connected to the top of the box body, a discharge port on the top of the pusher plate, a threaded sleeve fixedly connected to the rear end of the pusher plate, a positioning frame fixedly connected to the bottom of the pusher plate, two pressure plates rotatably mounted inside the positioning frame, cylinders on both sides of the outer wall of the box body, a hollow structure inside the box body, a screening box fixedly mounted on the top of the inner wall of the box body, a feeding port on both sides of the outer wall of the screening box, and two third motors fixedly mounted on the surface of the screening box.

[0008] Preferably, springs are fixedly installed on both sides of the inner wall of the positioning frame, the top of the springs is fixedly connected to the bottom of the pressure plate, and a limit rod is fixedly installed inside the positioning frame, with the limit rod abutting against the top of the pressure plate.

[0009] Preferably, the bottom end of the feeding box is connected to the top end of the screening box, and the output shafts of the two third motors are fixedly connected to the second crushing rollers, and the two second crushing rollers are rotatably installed inside the screening box.

[0010] Preferably, a flow divider is rotatably installed inside both of the feed inlets, and a connecting seat is fixedly connected to one side of the flow divider.

[0011] Preferably, an adjusting plate is rotatably mounted inside the mounting bracket, the cylinder is fixedly mounted on one side of the outer wall of the adjusting plate, and the output shaft of the cylinder is rotatably connected to the connecting seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the first motor controls the first crushing roller to crush the straw. The feeding port at the top of the pusher plate facilitates the placement and positioning of the straw. The pressure plates at both ends can clamp and limit the straw, keeping it vertically at the top of the feeding box for easy crushing.

The crushing operation can be carried out without the need for personnel to hold the straw continuously. During operation, personnel can stay away from the box to avoid floating debris affecting their physical and mental health.

[0013] 2. In this utility model, the operation of the second crushing roller is controlled by the third motor, which can crush the straw fragments processed inside the feeding box into smaller straw fragments. The cylinder controls the angle and position of the diverter plate, which can directly collect the straw fragments after the first crushing. The size of the straw fragments can be selected by itself. When smaller straw fragments are needed, they can be obtained without secondary processing. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 like Figures 1-6As shown, this utility model provides a technical solution: a barley straw crushing device, including a box body 1, a discharge port 101 on the surface of the box body 1, mounting brackets 11 fixedly connected to both sides of the outer wall of the box body 1, a feeding box 2 fixedly connected to the top of the box body 1, two first motors 21 fixedly mounted on the surface of the feeding box 2, a fixing plate 3 fixedly connected to the top of the box body 1, a second motor 31 fixedly mounted on the top of the fixing plate 3, a screw 32 fixedly connected to the output end of the second motor 31, a pusher plate 4 slidably connected to the fixing plate 3 on the top of the box body 1, a discharge port 401 on the top of the pusher plate 4, a threaded sleeve 41 fixedly connected to the rear end of the pusher plate 4, and a positioning frame 42 fixedly connected to the bottom of the pusher plate 4. Two pressure plates 43 are rotatably installed inside the positioning frame 42. Cylinders 5 are provided on both sides of the outer wall of the housing 1. The interior of the housing 1 is a hollow structure. The output shafts of the two first motors 21 are fixedly connected to the first crushing rollers 22. The two first crushing rollers 22 are rotatably installed inside the feeding box 2. The threaded sleeve 41 is threadedly installed on the surface of the screw 32. The two pressure plates 43 are symmetrically arranged at both ends inside the positioning frame 42. Blades 44 are fixedly connected to the bottom of the pressure plates 43. The two blades 44 abut against each other. Springs 45 are fixedly installed on both sides of the inner wall of the positioning frame 42. The top of the springs 45 is fixedly connected to the bottom of the pressure plates 43. Limiting rods 46 are fixedly installed inside the positioning frame 42. The limiting rods 46 abut against the top of the pressure plates 43.

[0018] In this embodiment, the discharge port 401 at the top of the pusher plate 4 can position and place the straw, so that the straw can be neatly placed on the top of the feeding box 2, preventing the straw from tilting during crushing and affecting the crushing quality. The springs 45 at both ends support the pressure plates 43 on both sides, so that the pressure plates 43 on both sides can press and limit the straw inside the positioning frame 42. The second motor 31 controls the rotation of the screw 32. At the same time, the threaded sleeve 41 and the screw 32 are threadedly connected, so that when the second motor 31 drives the screw 32 to rotate, it can control the pusher plate 4 to move downward. The blade 44 is inclined so that it can be embedded in the straw when moving downward, so that it can drive the straw down together. The first motor 21 controls the operation of the first crushing roller 22. The operation of the first crushing roller 22 can cut and crush the straw. At the same time, the pusher plate 4 can push the straw downward to complete the crushing. The limiting rod 46 can limit the angle of the pressure plate 43 to prevent the pressure plate 43 from flipping when the straw moves.

[0019] Example 2 like Figures 1-6As shown, a screening box 6 is fixedly installed on the top of the inner wall of the box 1. The screening box 6 has material inlets 601 on both sides of its outer wall. Two third motors 61 are fixedly installed on the surface of the screening box 6. The feeding box 2 has a hollow structure inside. The bottom of the feeding box 2 is connected to the top of the screening box 6. The output shafts of the two third motors 61 are fixedly connected to second crushing rollers 62. The two second crushing rollers 62 are rotatably installed inside the screening box 6. Diverting plates 63 are rotatably installed inside the two material inlets 601. A connecting seat 64 is fixedly connected to one side of the diverting plate 63. An adjusting plate 12 is rotatably installed inside the mounting frame 11. A cylinder 5 is fixedly installed on one side of the outer wall of the adjusting plate 12. The output shaft of the cylinder 5 is rotatably connected to the connecting seat 64.

[0020] In this embodiment, the screening box 6 is installed at the bottom of the feeding box 2, allowing the crushed straw fragments processed inside the feeding box 2 to flow into the screening box 6. The third motor 61 controls the operation of the second crushing roller 62, thereby enabling secondary processing of the crushed straw fragments. Compared to the first crushing roller 22, the second crushing roller 62 can crush finer fragments. The output shaft of the cylinder 5 is connected to the connecting seat 64, allowing the cylinder 5 to drive the diverter plate 63 to rotate. The adjusting plate 12 can rotate to prevent the cylinder 5 from getting stuck during adjustment. The diverter plates 63 on both sides rotate inward simultaneously and abut against each other, covering the top of the second crushing roller 62. The diverter plates 63 at both ends are in an inclined state, and the feed inlet 601 can directly discharge the crushed straw fragments from the feeding box 2 without secondary crushing, thereby obtaining larger straw fragments and enabling control and selection of the size of the straw fragments.

[0021] Working principle: The barley straw to be crushed is pushed into the feeding port 401. The bottom end of the straw passes through the positioning frame 42 and is located at the top of the first crushing roller 22. The pressure plates 43 on both sides press and limit the straw, keeping it in a vertical position. Then, the second motor 31 is started to drive the screw 32 to rotate. The threaded sleeve 41 drives the pusher plate 4 to descend. The second motor 31 is a servo motor, which can drive its connecting parts to rotate in both directions. Because the blade 44 is inclined, it embeds into the straw when it moves downward, thus driving the straw to descend together. The first motor 21 is started to drive the first crushing roller 22 to rotate, which can crush the straw. Then, the second motor 31 drives the pusher plate 4 to rise, the blade 44 separates from the straw, and the top of the straw is put back into the feed. The clamping and repeated lowering of the pusher plate 4 gradually pushes the straw downwards into the feeding box 2 for crushing. When smaller straw fragments are needed, the cylinder 5 controls the diversion plate 63 to remain vertical. At this time, the inside of the screening box 6 is in a flow state, and the crushed straw fragments fall onto the top of the second crushing roller 62. By starting the third motor 61, the second crushing roller 62 can be driven to run, which can perform secondary crushing of the smaller straw fragments. When larger straw fragments are needed, the cylinder 5 is started to push the diversion plate 63 to rotate. The diversion plates 63 on both sides rotate inwards at the same time and are in an inclined state. The straw fragments inside the screening box 6 flow directly out from the feed port 601 and are discharged from the discharge port 101. At this time, larger straw fragments can be obtained, and the size of the straw fragments can be controlled and selected.
