Abstract
Description
Technical Field
[0001] This utility model relates to the field of straw recycling, and more specifically, to a straw recycling device that accelerates straw decomposition. Background Technology
[0002] Straw is a general term for the stems and leaves (ears) of mature crops. In agricultural production, the treatment of crop straw has always been a key issue hindering the green development of agriculture. Traditional straw treatment methods mainly include open burning, direct return to the field, and composting. Open burning of straw produces large amounts of smoke, sulfur dioxide, and other pollutants, exacerbating air pollution and posing a fire hazard. Direct return to the field, while achieving resource recycling, leads to slow straw decomposition, easily causing loose soil structure and affecting the sowing and growth of the next season's crops. Traditional composting relies on natural fermentation, which takes months or even years, and the uneven distribution of microorganisms and insufficient material mixing during composting result in low fermentation efficiency, failing to meet the agricultural demand for rapid straw treatment. Existing straw treatment equipment has certain shortcomings. Current equipment only has simple crushing functions and lacks the ability to deeply process straw to accelerate decomposition. Some equipment with fermentation functions has unreasonable designs in the material mixing stage, failing to ensure sufficient mixing of microorganisms, chemicals, and straw, resulting in microorganisms being unable to effectively decompose cellulose, hemicellulose, and other components in the straw. How to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides a straw recycling device that accelerates straw decomposition. It aims to improve the shortcomings of existing straw processing equipment. Existing straw processing equipment only has a simple crushing function and lacks the ability to deeply process straw to accelerate decomposition. Some equipment with fermentation function has unreasonable design in the material mixing process, which cannot ensure that the inoculum, medicine and straw are fully mixed, resulting in the problem that microorganisms cannot effectively decompose the cellulose, hemicellulose and other components in the straw.
[0004] This utility model is implemented as follows: a straw recycling device for accelerating straw decomposition includes a decomposition pot, a stirring mechanism installed at one end of the decomposition pot, a conveying mechanism installed on one side of the decomposition pot, a cutting mechanism installed at the upper end of the conveying mechanism, and an impact mechanism installed on one side of the conveying mechanism.
[0005] In a preferred embodiment of this utility model, the stirring mechanism includes a motor, which is installed on the upper end of the decomposition vessel. The stirring rod is rotatably installed on the inner end of the decomposition vessel and is driven by the motor. A first stirring rod and a second stirring rod are installed on the outer side of the stirring rod. The second stirring rod is inclined and the first stirring rod is positioned above the second stirring rod.
[0006] In a preferred embodiment of this utility model, multiple sets of the first stirring rod and the second stirring rod are arranged, and a feed pipe is connected to the upper end of the decomposition vessel, with a valve installed on the feed pipe.
[0007] In a preferred embodiment of this invention, the second stirring rod is disposed on both sides of the stirring rod, with the two stirring rods on both sides having different inclination directions and being symmetrically arranged with respect to the center of the stirring rod. Medicine, microbial inoculum, and decomposition aids, such as livestock manure and sawdust, are fed into the decomposition vessel through a feed pipe. The first and second stirring rods are driven by a motor to stir the materials fed into the decomposition vessel from the conveying mechanism. The inclined second stirring rods, symmetrically arranged with respect to the center of the stirring rod, cause the materials to be continuously turned upwards while being stirred, resulting in more uniform stirring. Simultaneously, the first stirring rod enhances the stirring effect, ensuring uniform distribution of microorganisms and avoiding incomplete local decomposition. A discharge chute is provided at the bottom of one side of the decomposition vessel.
[0008] In a preferred embodiment of this utility model, the conveying mechanism includes a conveying box, which is connected and installed on one side of the decaying vessel. A second motor is installed on one side of the conveying box, and a conveying auger is rotatably installed inside the conveying box. The conveying auger is driven by the second motor, and the material is conveyed into the decaying vessel by the conveying auger driven by the second motor.
[0009] In the preferred embodiment of this utility model, a cutting blade is provided on the outside of the conveying auger. After the material is cut by the cutting mechanism, the material is cut a second time, making the material cut more uniform and reducing the decay time of the straw material.
[0010] In a preferred embodiment of this utility model, the cutting mechanism includes a hopper connected to the upper end of the conveyor box. A housing is connected to the upper end of the hopper, and a feed inlet is connected to the upper end of the housing. A third motor is installed on the upper end of the housing, and an installation rod is rotatably installed inside the housing. The installation rod is driven by the third motor, and multiple sets of second cutting blades are installed on the outside of the installation rod. A filter plate is installed on the inner wall of the housing. Straw material is fed in through the feed inlet. The installation rod is driven by the third motor to cut the straw material with the second cutting blades. The filter plate blocks the material. The filter plate has a large opening and works with multiple sets of second cutting blades to prevent the filter plate from reducing its feeding effect. After the material is cut into a suitable size, it is sent into the conveyor box. Support members are provided on the outside of both the housing and the conveyor box.
[0011] In a preferred embodiment of this invention, the impact mechanism includes a mounting plate mounted on one side of the housing. A fourth motor is mounted on one side of the mounting plate, and a rotating plate is rotatably mounted on the other side of the mounting plate. The rotating plate is driven by the fourth motor.

A guide sleeve is provided on one side of the mounting plate in conjunction with the guide rod. An impact block is mounted on one end of the guide rod. The rotating plate is driven by the fourth motor, causing the rotating plate to move the hinge rod and the guide rod through the guide sleeve, so that the impact block impacts the housing, preventing the shredded small-mass material from adhering to the inner wall of the decay reactor and reducing cleaning hassles.
[0012] The beneficial effects of this utility model are as follows: This utility model provides a straw recycling device that accelerates straw decomposition. During use, straw material is fed into the inlet. A third motor drives the mounting rod, causing the second cutting blade to cut the straw material. A filter plate blocks the material, ensuring it is cut to a suitable size before being fed into the conveying box. Simultaneously, a fourth motor drives a rotating plate, causing the rotating plate to move the hinge rod and guide rod through the guide sleeve, allowing the impact block to strike the shell, preventing material from adhering to the inner wall of the decomposition chamber 100 and reducing cleaning hassles. A second motor drives a conveying auger, which transports the material into the decomposition chamber. A feed pipe delivers the agent into the decomposition chamber. A motor drives a first and second stirring rod to stir the material delivered from the conveying mechanism into the decomposition chamber. The inclined second stirring rod, symmetrically positioned around the center of the stirring rod, continuously tumbles the material while stirring, resulting in more uniform mixing. This, combined with the first stirring rod, enhances the stirring effect. The device uses a cutting mechanism in conjunction with a conveying mechanism to cut the straw material, which accelerates the subsequent decomposition of the straw. The mixing mechanism further mixes the material, resulting in a better mixing effect and a more uniform mixture of the agent and the material. Attached Figure Description

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Please see Figures 1-4The present invention provides a technical solution: a straw recycling device for accelerating straw decomposition, comprising a decomposition pot 100, a stirring mechanism 200 installed at one end of the decomposition pot 100, a conveying mechanism 300 installed on one side of the decomposition pot 100, a cutting mechanism 400 installed at the upper end of the conveying mechanism 300, and an impact mechanism 500 installed on one side of the conveying mechanism 300.
[0021] In some specific implementations, the stirring mechanism 200 includes a motor 210, which is mounted on the upper end of the decomposition vessel 100. A stirring rod 220 is rotatably mounted on the inner end of the decomposition vessel 100. The stirring rod 220 is driven by the motor 210. A first stirring rod 230 and a second stirring rod 240 are mounted on the outer side of the stirring rod 220. The second stirring rod 240 is inclined, and the first stirring rod 230 is positioned above the second stirring rod 240.
[0022] In some specific implementation schemes, multiple sets of the first stirring rod 230 and the second stirring rod 240 are arranged, and a feed pipe 250 is connected to the upper end of the decomposition vessel 100, and a valve 260 is provided on the feed pipe 250.
[0023] In some specific implementations, the second stirring rod 240 is disposed on both sides of the stirring rod 220. The second stirring rods 240 on both sides of the stirring rod 220 are inclined in different directions and are symmetrically arranged with respect to the center of the stirring rod 220. The medicine, inoculum and decomposition aids (such as livestock and poultry manure and sawdust) are fed into the decomposition vessel 100 through the feed pipe 250. The first stirring rod 230 and the second stirring rod 240 are driven by the motor 210 to stir the material fed into the decomposition vessel 100 from the conveying mechanism 300. The inclined and symmetrically arranged second stirring rod 240 makes the material continuously turn upward while being stirred, so that the stirring of the material is more uniform. At the same time, it works with the first stirring rod 230 to enhance the stirring effect, ensure uniform distribution of microorganisms, and avoid insufficient local decomposition. A discharge chute is provided at the bottom of one side of the decomposition vessel 100.
[0024] In some specific implementations, the conveying mechanism 300 includes a conveying box 310, which is connected and installed on one side of the decaying vessel 100. A second motor 320 is installed on one side of the conveying box 310, and a conveying auger 330 is rotatably installed inside the conveying box 310. The conveying auger 330 is driven by the second motor 320, and the material is conveyed into the decaying vessel 100 by the conveying auger 330 driven by the second motor 320.
[0025] In some specific implementation schemes, a cutting blade 340 is provided on the outside of the conveying auger 330. After the material is cut by the cutting mechanism 400, the cutting blade 340 performs a secondary cut, making the material cut more uniform and reducing the decay time of the straw material.
[0026] In some specific implementations, the cutting mechanism 400 includes a hopper 410, which is connected to and installed on the upper end of the conveyor box 310. A housing 420 is connected to and installed on the upper end of the hopper 410. A feed inlet 470 is connected to and installed on the upper end of the housing 420. A third motor 430 is installed on the upper end of the housing 420. An installation rod 440 is rotatably installed on the inner end of the housing 420. The installation rod 440 is driven by the third motor 430. Multiple sets of second cutting blades 450 are installed on the outside of the installation rod 440. A filter plate 460 is installed on the inner wall of the housing 420. Straw material is fed in through the feed inlet 470. The third motor 430 drives the mounting rod 440 to make the second cutting blade 450 cut the straw material. The filter plate 460 blocks the material. The filter plate 460 has a large opening and works with multiple sets of second cutting blades 450 to prevent the material feeding effect of the filter plate 460 from decreasing. After the material is cut into a suitable size, it is sent into the conveying box 310. Support members are provided on the outside of the housing 420 and the conveying box 310.
[0027] In some specific implementations, the impact mechanism 500 includes a mounting plate 510, which is mounted on one side of the housing 420. A fourth motor 520 is mounted on one side of the mounting plate 510, and a rotating plate 530 is rotatably mounted on the other side of the mounting plate 510. The rotating plate 530 is driven by the fourth motor 520. A hinge rod 540 is hinged to a non-central position on one side of the rotating plate 530, and a guide rod 550 is hinged to the other end of the hinge rod 540. A guide sleeve 560 is provided on one side of the mounting plate 510 in conjunction with the guide rod 550. An impact block 570 is mounted on one end of the guide rod 550. The rotating plate 530 is driven by the fourth motor 520, causing the rotating plate 530 to drive the hinge rod 540 and the guide rod 550 to move through the guide sleeve 560, so that the impact block 570 impacts the housing 420, preventing the shredded small-mass material from adhering to the inner wall of the decay vessel 100 and reducing cleaning trouble.
[0028] Working principle: During use, straw material is fed in through the feed inlet 470. The third motor 430 drives the mounting rod 440, causing the second cutting blade 450 to cut the straw material. The filter plate 460 blocks the material, ensuring it is cut to a suitable size before being fed into the conveying box 310. Simultaneously, the fourth motor 520 drives the rotating plate 530, causing the hinge rod 540 and guide rod 550 to move through the guide sleeve 560. This causes the impact block 570 to impact the shell 420, preventing material from adhering to the inner wall of the composting vessel 100 and reducing cleaning. To address the issue of material transport, the second motor 320 drives the conveying auger 330 to transport the material into the decay vessel 100. The agent is then fed into the decay vessel 100 through the feed pipe 250. The motor 210 drives the first stirring rod 230 and the second stirring rod 240 to stir the material delivered from the conveying mechanism 300 into the decay vessel 100. The second stirring rod 240, which is inclined and symmetrically positioned around the center of the stirring rod 220, continuously tumbles the material while it is being stirred, resulting in more uniform mixing. This, combined with the first stirring rod 230, enhances the stirring effect.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
