Description

Technical Field

[0001] This application relates to the field of weeding device technology, specifically to a cow dung weeding device. Background Technology

[0002] In animal husbandry, especially in large-scale dairy farms, a large amount of cow manure is produced daily. This manure is a high-quality organic fertilizer resource and usually needs to be collected, transported, and composted before being returned to the fields. However, weed seeds are often mixed in with cow bedding or feed, resulting in cow manure containing a large amount of weeds. If this untreated cow manure is applied directly to farmland, it will cause rampant weed growth, seriously affecting crop growth and increasing subsequent field management costs and pesticide use.

[0003] Currently, the methods for treating weeds in cow dung are relatively primitive and inefficient. A common method is to first pile up the cow dung and then separate it manually or using a simple vibrating screen before transportation or application. This method has the following significant drawbacks: Inefficient: It is highly dependent on manual labor, labor-intensive, and slow in processing, making it difficult to meet the continuous processing needs of large-scale farms.

[0004] Poor separation effect: manual sorting is prone to omissions, while ordinary vibrating screens are prone to clogging due to the stickiness and moisture of cow dung, resulting in incomplete separation.

[0005] Low level of automation: It cannot be effectively integrated with modern cow manure conveying and processing systems, disrupting the continuity of the production process.

[0006] Therefore, there is an urgent need in this field for a specialized device that can be integrated into a cow manure conveying line, is highly automated, can effectively separate weeds, and operates stably. Summary of the Invention

[0007] The purpose of this application is to provide a cow dung weeding device to solve the problems in the prior art.

[0008] To achieve the above objectives, this application provides a cow dung weeding device, comprising: a frame, a drive unit, a drive shaft, a driven shaft, and a mesh belt, wherein... The drive unit includes a motor and a reducer, and the reducer is connected to the output shaft of the motor via a coupling or a chain. The drive shaft and driven shaft are mounted parallel to each other at both ends of the frame via a first bearing seat and a second bearing seat. The drive shaft is connected to the output end of the reducer. The mesh belt is fitted on the drive shaft and driven shaft. A sprocket or roller is mounted on the drive shaft. The sprocket or roller meshes with or rubs against the mesh belt. The surface of the mesh belt is textured or raised, and the mesh belt has mesh holes.

[0009] Optionally, it further includes: a guiding device, the guiding device comprising a plurality of guide wheels or guide rails disposed on both sides of the frame, the guide wheels or guide rails contacting the two side edges of the mesh belt.

[0010] Optionally, it further includes: a tensioning device, said tensioning device comprising a slide rail, a slider, and an adjusting bolt, wherein, Two parallel slide rails are fixedly mounted on the longitudinal beams on both sides of the frame. The axial direction of the slide rails is consistent with the length direction of the mesh belt. Two sliders (or sliding bearing seats) are nested on the two slide rails respectively. The two ends of the driven shaft are rotatably connected to the two sliders respectively through rolling bearings.

[0011] Optionally, a fixed seat with a threaded hole is welded to the driven shaft end of the frame. One end of the adjusting bolt is screwed into the fixed seat through a thread. The axis of the adjusting bolt is parallel to the axis of the slide rail. The other end of the adjusting bolt is connected to or directly abuts against the end face of the slider through a rotating pair.

[0012] Optionally, each of the adjusting bolts is further provided with two locking nuts, located on both sides of the fixing seat respectively.

[0016] The embodiments of this application have the following advantages: Highly efficient automated weeding: Utilizing a circulating mesh belt and its unique structural design, the system automatically separates and collects weeds while transporting cow manure, greatly improving processing efficiency and reducing reliance on manual labor.

[0017] Excellent anti-slip and anti-clogging performance: By using a mesh belt with a rough or specially textured surface, the friction with the cow dung is increased, ensuring the stability of cow dung transportation. The mesh design and natural vibration during transportation allow sticky cow dung to pass through, while weed fibers are effectively trapped and separated from the return section, fundamentally avoiding clogging.

[0018] Stable and reliable operation: The guide and tensioning devices ensure that the conveyor belt always runs smoothly along the preset track, effectively preventing problems such as belt deviation, jumping or excessive slack, extending the service life of the equipment and ensuring the continuity of the production process.

[0019] Highly integrated and practical: This device can be directly installed at the discharge end of existing conveying systems or used as an independent module. Its compact structure makes it easy to install and maintain. It not only improves the fertilizer quality of cow manure and reduces weed damage in farmland, but also provides key equipment support for clean production and resource utilization in livestock farms.

[0025] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0026] This application provides a cow dung weed removal device, see reference. Figures 1 to 3 ,include: Frame, drive unit, drive shaft, driven shaft, conveyor belt.

[0027] The frame is welded from structural steel, providing support and a foundation for the entire device.

[0028] The drive unit includes a motor and a reducer. The motor is preferably a variable frequency motor to adjust the running speed of the conveyor belt and adapt to cow manure with different moisture contents. The reducer is connected to the output shaft of the motor via a coupling or chain to reduce the rotational speed and increase the torque.

[0029] The drive shaft and driven shaft are mounted parallel to each other at both ends of the frame via a first bearing housing and a second bearing housing. The drive shaft is connected to the output end of the reducer and is driven to rotate by it. A mesh belt is fitted onto the drive shaft and driven shaft, and a sprocket or roller is mounted on the drive shaft, which meshes with or frictionally contacts the mesh belt.

[0030] The mesh belt is woven or stamped from high-strength, corrosion-resistant metal materials to form a continuous ring structure. The mesh belt is fitted onto the drive and driven shafts, supporting and driving their cyclical operation. The surface of the mesh belt has textured or raised areas to increase friction, and it features precisely designed mesh openings to ensure that most cow dung passes through smoothly while effectively hooking and trapping weeds.

[0031] In some embodiments, the device further includes a guiding device comprising a plurality of guide wheels or guide rails disposed on both sides of the frame, the guide wheels or guide rails contacting the two side edges of the mesh belt to limit the lateral movement of the mesh belt during operation and prevent it from deviating from its designated path.

[0032] In some embodiments, the device further includes a tensioning device, which comprises a slide rail, a slider, and an adjusting bolt. Two parallel slide rails are fixedly mounted on the longitudinal beams on both sides of the frame. The axial direction of the slide rails is consistent with the length direction of the mesh belt. Two sliders (or sliding bearing seats) are nested on the two slide rails respectively and can slide along the axial direction of the slide rails. The two ends of the driven shaft are rotatably connected to the two sliders respectively through rolling bearings. Therefore, the driven shaft and the bearing seats at both ends are supported on the slide rails as a whole and have the ability to slide.

[0033] At the rear end of the frame (i.e., the end where the driven shaft is located), a fixed seat with a threaded hole is welded. One end of the adjusting bolts (usually two, symmetrically arranged on the left and right sides) is screwed into the fixed seat via threads. The axis of the adjusting bolt is parallel to the axis of the slide rail. The other end of the adjusting bolt (usually the screw head) is connected via a revolute joint (e.g., through a thrust ball bearing) or directly abuts against the end face of the slider. This design ensures that when the adjusting bolts are rotated, friction is reduced, preventing the slider from rotating and causing it to produce only pure axial movement.

[0034] In some embodiments, each adjusting bolt is further provided with two locking nuts, located on both sides of the fixed seat. After the slider (i.e., the driven shaft) is moved to a predetermined position by rotating the adjusting bolt to achieve the required tension of the conveyor belt, the two locking nuts are tightened to firmly clamp the fixed seat. This securely fixes the adjusting bolt, preventing it from rotating on its own due to vibration during equipment operation, which would lead to tension failure.

[0035] Specifically, the tensioning device is used to adjust the tension of the conveyor belt. In this embodiment, the tensioning device adopts a spiral tensioning mechanism, which is achieved by adjusting the position of the bearing seats at both ends of the driven shaft on the frame slide rail. Maintaining appropriate tension can prevent the conveyor belt from slipping and abnormal wear. Working principle and adjustment method: When it is necessary to tension the conveyor belt, the operator uses a tool (such as a wrench) to simultaneously and synchronously rotate the adjusting bolts on both sides clockwise. The rotational movement of the adjusting bolts is converted into forward linear motion through the threaded joint, thereby pushing the slider and the driven shaft it carries to move along the slide rail away from the drive shaft, thus tightening the conveyor belt. Conversely, if it is necessary to loosen the conveyor belt (such as for replacement or maintenance), the adjusting bolts are rotated counterclockwise. The slider is pushed back by the contraction force of the conveyor belt itself, moving towards the drive shaft, and the conveyor belt is loosened accordingly. Through this design, the operator can control the position of the driven shaft very precisely and conveniently, thereby achieving stepless adjustment of the conveyor belt tension and ensuring that the tension is evenly distributed on both sides of the conveyor belt.

[0036] In some embodiments, the system further includes a weed collection trough disposed below the return section (lower half) of the mesh belt for catching weeds falling from the mesh belt.

[0037] Working principle: During operation, wet cow dung containing weeds is conveyed from upstream equipment (such as a manure scraper) to the upper working surface of the conveyor belt in this device. The motor is started, and power is transmitted to the drive shaft via a reducer, driving the sprocket and conveyor belt in a cyclical motion. The conveyor belt, relying on the friction of its surface, moves the cow dung towards the discharge end.

[0038] During this process, due to vibration and friction, the sticky cow dung moves with the conveyor belt, while the more resilient weeds are hooked and retained on the surface of the belt by the mesh or surface structure. When the conveyor belt with weeds on it turns around and enters the return section after passing the drive shaft or driven shaft, the weeds lose their adhesion due to the change in gravity and direction of motion, and automatically fall into the weed collection trough directly below, thus achieving continuous automatic separation of cow dung and weeds.

[0039] The partially separated cow dung falls from the discharge end of the conveyor belt and enters the subsequent transport vehicle or composting area, while the weeds collected in the weed collection trough are cleaned regularly.

For example, two consecutive functions and steps may actually be executed or implemented substantially in parallel, and they may sometimes be executed or implemented in reverse order, depending on the functions involved.
