Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural equipment technology, specifically to an integrated device for crushing and shredding grain and straw. Background Technology
[0002] As a byproduct of agricultural production, straw is characterized by its large yield and wide distribution. With the improvement of agricultural mechanization and the promotion of ecological agriculture, the resource utilization of straw has become a key link in the sustainable development of agriculture. At present, the main utilization pathways of straw include feed, fertilizer, energy and substrate.
[0003] In existing technologies, integrated crushing and shredding devices for straw generally lack automatic cutting functions, requiring manual pre-processing or direct input of whole straw. Manual pre-processing is labor-intensive, inefficient, and makes it difficult to ensure the uniformity of straw length. Direct input of whole straw requires the equipment to overcome greater resistance during the crushing process of long straw, resulting in increased motor load, accelerated blade wear, increased energy consumption, and shortened equipment life.
[0004] In view of the above, this application is hereby submitted. Utility Model Content
[0005] The purpose of this utility model is to provide an integrated device for crushing and shredding straw to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides an integrated device for crushing and shredding straw, including an installation box. Inside the installation box, a cutting assembly is installed. The cutting assembly includes a first motor installed on the inner wall of the installation box. The output end of the first motor is connected to a first spur gear. A first connecting rod is slidably connected to one side of the outer wall of the first spur gear. A second spur gear is meshed with the bottom end of the first spur gear. A second connecting rod is slidably connected to one side of the outer wall of the second spur gear. A first moving block is slidably connected to one end of both the first and second connecting rods. A cutter head is fixedly connected to the outer wall of each first moving block on the side away from the first motor.
[0007] Furthermore, a second motor is installed inside the mounting box. The output end of the second motor is connected to a worm gear. The outer walls of the two sides of the worm gear are respectively meshed with a first cylindrical turntable and a second cylindrical turntable. A first roller is fixedly connected to one outer wall of the first cylindrical turntable, and a second roller is fixedly connected to one outer wall of the second cylindrical turntable. A second moving block is rotatably connected to the end of the second roller away from the second cylindrical turntable. A lead screw is threadedly connected to the inner wall of the second moving block, and a third motor is rotatably connected to the bottom end of the lead screw.
[0008] Furthermore, a display screen is installed on one outer wall of the housing, and multiple control buttons are installed on the outer wall of the same side of the display screen. A conveyor frame is installed on one outer wall of the housing, and a conveyor belt is installed on the inner bottom wall of the conveyor frame.
[0009] Furthermore, the side of the second motor furthest from the output end is fixedly connected to the inner wall of the mounting box, while the lead screw is rotatably connected to the inner wall of the mounting box.
[0010] Furthermore, one outer wall of each of the two first moving blocks is slidably connected to the mounting box, and the cutter head is made of a high-hardness material.
[0011] Furthermore, a sliding column is installed on one side of the outer wall of both the first and second spur gears, and the first and second spur gears are slidably connected to the first and second connecting rods through the sliding column.
[0012] Furthermore, the outer wall of the first motor away from the output end is fixedly connected to the inner wall of the mounting box, and the ends of the first connecting rod and the second connecting rod away from the first moving block are rotatably connected to the inner wall of the mounting box.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The cutting component performs reciprocating cutting motions on long straws, ensuring that the straws are cut to a basically uniform length. Straws of uniform length can be better crushed and shredded after entering the equipment, thereby improving production efficiency and product quality. It also reduces the resistance that the equipment needs to overcome during the crushing process, reduces the load on the motor, reduces energy consumption, lowers production costs, and extends the service life of the components.
[0014] 2. The distance between the two rollers is controlled by the adjusting component, which, together with the cutting component, ensures that the cut straw is further crushed evenly after entering the crushing roller. By adjusting the distance between the rollers by the adjusting component, the equipment can adapt to straws with different characteristics, thus improving the flexibility and adaptability of the equipment.

[0017] 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.
[0018] Please see Figures 1-5 This utility model provides a technical solution: an integrated device for crushing and shredding straw, including a mounting box 1. A cutting assembly is installed inside the mounting box 1. The cutting assembly includes a first motor 3 installed on the inner wall of the mounting box 1. The output end of the first motor 3 is connected to a first spur gear 4. After the first motor 3 starts, it drives the first spur gear 4 to rotate synchronously. A first connecting rod 5 is slidably connected to one side of the outer wall of the first spur gear 4. When the first spur gear 4 rotates, it drives the first connecting rod 5 to swing along with the rotation of the first spur gear 4. The bottom of the first spur gear 4... A second spur gear 6 is engaged with the first spur gear 4. A second connecting rod 7 is slidably connected to one side of the outer wall of the second spur gear 6. The first spur gear 4 drives the second spur gear 6 to rotate in the opposite direction through engagement. The second spur gear 6 then drives the second connecting rod 7 to swing. A first moving block 8 is slidably connected to one end of the first connecting rod 5 and the second connecting rod 7. A cutter head 9 is fixedly connected to the outer wall of each first moving block 8 away from the first motor 3. The first moving block 8 is slidably connected to the inner wall of the mounting box 1. Through the reciprocating swing of the first connecting rod 5 and the second connecting rod 7, the cutter head 9 is driven to perform a relative cutting action.
[0019] See Figure 4 , Figure 5Inside the mounting housing 1, a second motor 10 is also installed. The output end of the second motor 10 is connected to a worm gear 11. The rotation of the second motor 10 provides power, causing the worm gear 11 to rotate. The outer walls of both sides of the worm gear 11 are respectively meshed with a first cylindrical turntable 12 and a second cylindrical turntable 14. The rotation of the worm gear 11 is converted into synchronous, opposite rotation of the first cylindrical turntable 12 and the second cylindrical turntable 14 through meshing. A first roller 13 is fixedly connected to one outer wall of the first cylindrical turntable 12, and a second roller 13 is fixedly connected to one outer wall of the second cylindrical turntable 14. Two rollers 15, the first roller 13 and the second roller 15 are fixedly connected and start to rotate. The surface of the roller 15 is equipped with crushing teeth for crushing and shredding straw. The end of the second roller 15 away from the second cylindrical turntable 14 is rotatably connected to a second moving block 16. The inner wall of the second moving block 16 is threadedly connected to a lead screw 17. The bottom end of the lead screw 17 is rotatably connected to a third motor 18. The third motor 18 drives the lead screw 17 to rotate, thereby realizing the axial movement of the second moving block 16, and thus adjusting the position of the second roller 15 according to different working requirements.
[0020] See Figure 1 A display screen 19 is installed on one outer wall of the mounting box 1. Multiple control buttons are installed on one outer wall of the display screen 19. The display screen 19 is used to display the operating parameters of the equipment so that the operator can quickly understand and control the equipment.
[0021] See Figure 1 A conveyor frame 2 is installed on one outer wall of the housing 1. A conveyor belt is installed on the inner bottom wall of the conveyor frame 2. The conveyor frame 2 is aligned with the inlet of the cutting component to ensure the transport of straw materials. At the same time, the surface of the conveyor belt has anti-slip texture to ensure the stability of the straw during the transport process.
[0022] See Figure 2 , Figure 3 The outer wall of the first motor 3 away from the output end is fixedly connected to the inner wall of the mounting box 1. The ends of the first connecting rod 5 and the second connecting rod 7 away from the first moving block 8 are rotatably connected to the inner wall of the mounting box 1. The first connecting rod 5 and the second connecting rod 7 are rotatably connected to the inner wall of the mounting box 1 to reduce frictional resistance and energy loss during the movement and improve transmission efficiency.
[0023] Working principle: After the first motor 3 starts, it drives the first spur gear 4 to rotate, which in turn drives the first connecting rod 5 to swing. At the same time, the first spur gear 4 meshes with the second spur gear 6 to rotate in the opposite direction, which drives the second connecting rod 7 to swing synchronously. The swinging of the first connecting rod 5 and the second connecting rod 7 drives the first moving block 8 to slide back and forth along the inner wall of the mounting box 1, which drives the cutter head 9 fixed on one side of the first moving block 8 to perform relative cutting action on the material, thereby cutting the straw. Meanwhile, the second motor 10 drives the worm gear 11 to rotate, and the first cylindrical turntable 12 and the second cylindrical turntable 14 meshing on both sides of the worm gear 11 begin to rotate synchronously in opposite directions, causing the first roller 13 and the second roller 15 to start rotating, crushing and shredding the cut straw. At the same time, the third motor 18 drives the lead screw 17 to rotate, which drives the second moving block 16 to move vertically up and down through the threaded connection, thereby adjusting the distance between the second roller 15 and the first roller 13 to adapt to different straw crushing needs.
