Description

Technical Field

[0001] This utility model relates to the field of straw crushing technology, and in particular to a rice straw crushing device for processing rice seedling substrate. Background Technology

[0002] Rice straw crushing equipment is used for processing rice seedling substrate. It is a key piece of equipment that efficiently converts rice straw into raw materials for seedling substrate. It usually consists of a feed inlet, crushing chamber, blade assembly, screen, and discharge outlet. After the straw is fed in through the feed inlet, the high-speed rotating blade assembly cuts and crushes the straw to form fine materials.

[0003] In the processing of rice seedling substrate, existing straw crushing and filtering devices play an important role. For example, some traditional crushing devices typically use high-speed rotating blades to cut the straw. After the straw enters through the feed inlet, it is initially crushed under the strong cutting force of the blades. In terms of filtration, screens are commonly used for screening. When the crushed straw material passes through the screen, fine particles that meet the particle size requirements of the seedling substrate pass through the screen and become usable substrate raw materials.

[0004] Current rice straw crushing and filtering devices have significant shortcomings in their filtration function. Most devices have fixed screens, relying solely on the material's own gravity to pass through the screen holes, resulting in low filtration efficiency. Over time, local blockages can occur, causing a large amount of substandard straw to remain on the screen surface, making it impossible to filter quickly. Therefore, a rice straw crushing device for rice seedling substrate processing is proposed to solve the above problems. Utility Model Content

[0023] 1. In this utility model, the worker puts rice straw into the bucket, starts the drive motor, and the drive wheel drives the driven wheel to rotate through the belt. The drive wheel and the driven wheel drive the spiral blade to rotate at high speed, crushing the straw and dropping it into the filter disc.

The waste hopper, with the conveying pipe connected to the bottom, transports the bellflower stems back to the top of the inverted bucket. These incompletely crushed bellflower stems are put back into the inverted bucket and crushed a second time by the spiral blade. Attached Figure Description

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a rice straw crushing device for processing rice seedling substrate. It includes a base 1, with a fixed rod 2 fixedly connected inside the base 1. A traction motor 3 is fixedly connected to the top of the fixed rod 2, and a turntable 4 is fixedly connected to the drive end of the traction motor 3. The drive end of the traction motor 3 drives the turntable 4 to rotate at a uniform speed. A limiting block 5 is fixedly connected to the outer wall of the turntable 4. As the turntable 4 rotates, the limiting block 5 also performs circular motion. A push rod 6 is rotatably connected to the outer wall of the limiting block 5, cleverly converting the circular motion into the linear motion of the push rod 6. A substrate tray 7 is rotatably connected to one end of the push rod 6. A filter tray 8 is fixedly connected to the top of the substrate tray 7, and the bottom of the filter tray 8 contacts the outer wall of the transmission hopper 18. A retaining wheel 23 is rotatably connected to the bottom of the substrate tray 7, and the outer wall of the retaining wheel 23 is slidably connected to the outer wall of the fixed rod 2, precisely engaging with the outer wall of the fixed rod 2, allowing the substrate tray 7 to move along the fixed rod 2. Rod 2 slides smoothly. A crushing component is fixedly connected to the top of base 1. The crushing component includes a drive motor 9. The bottom of drive motor 9 is fixedly connected to the top of base 1. A drive wheel 10 is fixedly connected to the drive end of drive motor 9. A driven wheel 12 is rotatably connected inside base 1. A belt 11 is coupled to the outside of drive wheel 10 and driven wheel 12. A bucket 13 is fixedly connected to the top of base 1. Spiral blades 14 are fixedly connected to the outer walls of driven wheel 12 and drive wheel 10. One end of spiral blade 14 is rotatably connected to the inside of base 1. A substrate box 22 is slidably connected to the top of base 1. Rice straw is put into bucket 13. Spiral blades 14 on the outer walls of drive wheel 10 and driven wheel 12 rotate at high speed under the drive of the two wheels, crushing the straw. As substrate disc 7 moves, the qualified straw fragments are finally transported to substrate box 22 slidably connected to the top of base 1, completing the entire crushing process.

[0033] Reference Figure 3 and Figure 4A second drive motor 15 is fixedly connected to the top of the base 1. A second drive wheel 16 is fixedly connected to the drive end of the second drive motor 15. The outer wall of the second drive wheel 16 is rotatably connected to the top of the base 1. A second driven wheel 19 is fixedly connected to the top of the base 1. A conveyor belt 17 is externally coupled to the second drive wheel 16 and the second driven wheel 19. Multiple conveyor buckets 18 are fixedly connected to the outside of the conveyor belt 17. The multiple conveyor buckets 18 are evenly spaced and move synchronously with the operation of the conveyor belt 17. The outer wall of the conveyor bucket 18 contacts the outer wall of the waste hopper 20. When the conveyor bucket 18... When the device carrying the partially crushed bellflower root reaches the end of the equipment, its outer wall will precisely contact the outer wall of the waste hopper 20. With the help of the ingenious tilt angle design, the bellflower root is smoothly poured into the waste hopper 20. The waste hopper 20 is fixedly connected to the top of the base 1, and the conveying pipe 21 is fixedly connected to the bottom of the waste hopper 20. The outer wall of the conveying pipe 21 contacts the top of the bucket 13. The conveying pipe 21 extends downward at an incline, and its outer wall precisely connects with the top of the bucket 13, forming a smooth material transmission channel, so that the partially crushed bellflower root is put back into the bucket 13.

[0034] Working principle: The worker puts rice straw into the bucket 13 and starts the drive motor 9. The drive motor 9 drives the drive wheel 10 to rotate. The drive wheel 10 drives the driven wheel 12 to rotate via the belt 11. On one side of both the drive wheel 10 and the driven wheel 12, the spiral blades 14 are firmly fixed. When the two wheels rotate, the spiral blades 14 rotate at high speed, shredding the rice straw. Under the combined action of centrifugal force and gravity generated by the rotation, the shredded straw fragments fall precisely into the filter disc 8 below. The traction motor 3 is started, driving the turntable 4 to rotate. The surface of the turntable 4 has a limiting block 5, which is locked at the top of the push rod 6. As the turntable 4 continues to rotate, the limiting block 5... The system revolves around a central point, converting circular motion into linear motion. This continuously propels push rod 6 in reciprocating linear motion. Push rod 6 is connected to substrate tray 7, causing substrate tray 7 to move along a fixed track. The bottom of substrate tray 7 is fitted with a locking wheel 23, which has a specific groove on its outside. This allows it to precisely engage with the fixed rod 2 on the ground, ensuring the stability and accuracy of substrate tray 7 during movement. The top of substrate tray 7 is fixed with a filter tray 8, which has fine and uniform holes. After secondary screening, the finely crushed and qualified straw passes through the holes of filter tray 8 and falls into substrate tray 7. As substrate tray 7 moves, it is eventually transported into substrate box 22, completing the entire process of crushing and transporting rice straw.

[0035] Incompletely crushed straw falls into the conveyor hopper 18 through a back-and-forth motion. The drive motor 15 is activated, driving the drive wheel 16 to rotate. The drive wheel 16, via the conveyor belt 17, drives the driven wheel 19 to rotate. Multiple conveyor hoppers 18 are fixed to the surface of the conveyor belt 17. As the conveyor belt 17 continues to operate, these evenly distributed hoppers sequentially transport the loaded incompletely crushed straw to designated positions. When a hopper 18 reaches its end, its tilted body allows the straw to slide down and precisely fall into the waste hopper 20 below. The bottom of the waste hopper 20 is connected to a conveyor pipe 21. One end of the conveyor pipe 21 is firmly fixed to the bottom of the waste hopper 20, while the other end extends above the tilting hopper 13. The incompletely crushed straw is then re-input into the tilting hopper 13, allowing for secondary utilization. This not only improves the efficiency and quality of straw crushing but also minimizes material waste, achieving efficient resource recycling.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
