Description

[0002] With the development of large-scale animal husbandry, efficient treatment of livestock manure in breeding farms has become a key issue for environmental protection and resource recycling. At present, in the field of cleaning livestock manure in breeding farms, common cleaning equipment and methods mainly focus on the overall removal of livestock manure, without effectively separating the livestock manure and urine. This leads to an increase in cleaning difficulty and transportation cost during the cleaning process, and the useful components in the urine cannot be recycled separately, resulting in resource waste; at the same time, the mixed manure and urine are prone to bacterial growth, which is not conducive to subsequent treatment and environmental protection.

Detailed Implementation

[0035] To clearly understand the technical solution of this application, the following will describe in detail a manure removal device for livestock farms provided by this application, in conjunction with specific embodiments and accompanying drawings.

[0036] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0037] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "one embodiment," "some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0038] Example 1: This example provides a manure removal device for livestock farms, referencing... Figure 1 The diagram shows a three-dimensional structural schematic of a manure removal device for a livestock farm. As can be seen, the device includes a vehicle body 2, which serves as the basic load-bearing structure. A tracked walking mechanism is installed at the bottom of the vehicle body 2 to drive the equipment and is the executing component that enables the vehicle body 2 to move. A driver's cab 3 is located in the upper part of the vehicle body 2, forming an enclosed connection with it, providing operating space for the operator. A radar 1 is installed at the front top of the vehicle body 2 and is fixedly connected to it via a suitable mounting bracket and other components, used to detect the surrounding environment. A manure separation mechanism is located at the rear top of the vehicle body 2, realizing the manure separation function. A front shovel is connected to the front of the vehicle body 2 via a mechanical connection mechanism, enabling shoveling and loading actions.

[0039] For details, please refer to Figures 2-3 ,in, Figure 2 The diagram shown is a schematic of the installation structure of the sewage separation mechanism. Figure 3The diagram shows a separate structural schematic of the fecal-liquid separation mechanism. As can be seen from the two diagrams above, the mechanism includes a separation box 4, which serves as the basic supporting unit. The receiving end and storage end of the separation box 4 are different functional areas integrally formed within the box body. The receiving end has a ramp structure to guide the material in; the storage end is used to temporarily store feces and urine. The receiving end and storage end together constitute the main cavity of the separation box 4. The separation box 4 extends through the rear of the vehicle body 2 and is fixedly connected to it. The top of the separation box 4 is positioned above the vehicle body 2, and the bottom of the separation box 4 is positioned below the vehicle body 2. A filter frame 10 is installed inside the separation box 4, and the separation of feces and urine is achieved through the filter hole structure of the filter frame 10 itself. The servo motor 5 is installed on the outside of the separator 4. The servo motor 5 is connected to the manure baffle 6 via a rotating shaft. The rotating shaft is rotatably connected to the manure outlet, which can be used to discharge manure. After receiving a control signal, the servo motor 5 can drive the manure baffle 6 to rotate around the rotating shaft, thereby blocking or discharging the manure outlet. The manure guide plate 7 is installed at the outer end of the separator 4 and is placed below the manure outlet. It is used to guide the separated manure to move along a preset path and assist in transporting the manure to a designated location. The filter frame 10 is sloping, and the bottom of the filter frame 10 is opposite to the manure outlet. The urine outlet 9 is a drain port opened at the bottom of the separator 4. The solenoid valve 8 is installed on the urine outlet 9. The solenoid valve 8 controls the opening and closing of the urine outlet 9 to realize the discharge control of the separated urine. That is, when the solenoid valve 8 is open, the separated urine can be discharged from the separator 4 through the urine outlet 9. When it is closed, it is temporarily stored in the separator 4.

[0040] Based on the above structure and connections, the working principle of the fecal-liquid separation mechanism is as follows:

[0041] The first step involves conveying the material containing manure (cattle and sheep manure) to the receiving end of the separation box 4. The inclined structure at the receiving end guides the material to slide into the main cavity of the separation box 4, achieving initial material aggregation.

[0042] In the second step, after the material enters the separation box 4, it falls onto the filter rack 10 installed inside the box. Relying on the filter hole structure of the filter rack 10, urine permeates through the filter holes due to gravity and remains at the bottom of the separation box 4; while feces are trapped on the filter rack 10, completing the initial separation of feces and liquid.

[0043] Third, when it is necessary to discharge the separated urine, the control system issues a command to trigger the solenoid valve 8 installed at the urine outlet 9 to open. The urine temporarily stored at the bottom of the separation tank 4 is discharged from the separation tank 4 through the urine outlet 9; if it is not necessary to discharge, the solenoid valve 8 remains closed, and the urine continues to remain in the separation tank 4.

[0044] In the fourth step, when the filtered feces need to be discharged, the servo motor 5 receives a control signal and drives the baffle plate 6 to rotate around the shaft, opening the feces outlet on the separation box 4. The feces on the filter frame 10 slide down due to gravity and the slope, falling through the feces outlet to the feces guide plate 7 below, and then being transported to the designated processing location (such as a manure truck, fermentation device, etc.) along the preset path of the guide plate. After the feces are discharged, the servo motor 5 can drive the baffle plate 6 to reset, re-seal the feces outlet, and prepare for the next round of separation operation.

[0045] For details, please refer to Figure 4 The diagram shows the assembly structure of the mechanical connection mechanism. As can be seen, the mechanical connection mechanism includes four electric telescopic cylinders 15. These four electric telescopic cylinders 15 serve as basic support components and are all fixedly installed in the assembly slot at the front of the vehicle body 2. The telescopic ends of the electric telescopic cylinders 15 are connected to the lifting plate 12. The synchronous lifting action of the four electric telescopic cylinders 15 drives the lifting plate 12 to move up and down. Two tilting motors 13 are installed on the lifting plate 12 (in this embodiment, two tilting motors 13 are used). The output shafts of the two tilting motors 13 are fixedly connected to both ends of a pin shaft, which is fixedly connected to the main support arm 11. The synchronous rotation of the two tilting motors 13 drives the main support arm 11 to tilt, thereby adjusting the angle of the front shovel. The auxiliary support arm 14 is fixedly connected to the main support arm 11. The other ends of the main support arm 11 and the auxiliary support arm 14 are connected to the front shovel. The main and auxiliary support arms work together to support and transmit power to the front shovel, transmitting the power of the tilting motor 13 and the lifting action of the electric telescopic cylinder 15 to the front shovel, thereby realizing the lifting and tilting operation of the front shovel.

[0046] For details, please refer to Figure 5 The diagram shows a schematic of the front shovel's individual structure. As can be seen, the front shovel consists of two parts: a scraper section 17 and a guide section 16. These two parts are mechanically connected (e.g., by welding, bolting) to form a complete front shovel. The scraper section 17, as the actuator directly contacting the feces, is responsible for scooping up the feces. The guide section 16 receives the feces scooped up by the scraper section 17, providing a channel and structural foundation for subsequent material guiding. As an optimization, the channel size at the connection between the scraper section 17 and the guide section 16 is designed to gradually decrease, decreasing from large to small along the material conveying direction from the connection point (not shown in the diagram). After the scraper section 17 contacts and scoops up the feces, the overall angle of the front shovel can be adjusted using the mechanical connection mechanism. The purpose of adjusting the angle is to allow the feces scooped by the scraper section 17 to smoothly transition to the guide section 16. Then, guided by the structure of the guide section 16, the feces are precisely poured into the receiving end of the separation box 4, achieving a seamless transition from scooping to guiding.

[0047] For details, please refer to Figure 6The diagram shows a three-dimensional structural schematic of the tracked traveling mechanism. As can be seen, the tracked traveling mechanism includes a suspension frame 21, which is mounted on the corresponding side of the vehicle body 2. A beam arm 22 is fixedly connected to the suspension frame 21, serving to connect and support other components and transmit force. The first drive wheel 23 and the second drive wheel 19 are mounted on the beam arm 22. The drive motor on the suspension frame 21 can drive the first drive wheel 23 and the second drive wheel 19 to rotate, acting as the power output wheels of the tracked traveling mechanism. Through engagement with the track chain 18, the drive chain 18 is driven to move, thereby propelling the entire tracked traveling mechanism forward. A drive locking structure is mounted on the beam arm 22. When the vehicle body 2 is on a slope, the drive locking structure can lock the first drive wheel 23, restricting its rotation and assisting the vehicle body 2 in maintaining its position or achieving specific parking functions under conditions such as slopes. The track chain 18 surrounds the first drive wheel 23, the second drive wheel 19, the top tension wheel 20, and the bottom tension wheel 24, and engages with the first drive wheel 23 and the second drive wheel 19. Driven by the first drive wheel 23 and the second drive wheel 19, the track chain 18 circulates, realizing the walking function of the tracked traveling mechanism. The top tension wheels 20 (three in this embodiment) are fixed to the top of the beam arm 22, and the bottom tension wheels 24 (five in this embodiment) are installed at the bottom of the beam arm 22 through a buffer structure. The top tension wheels 20 and the bottom tension wheels 24 support the track chain 18, maintaining a certain tension and ensuring effective engagement between the track chain 18 and the drive wheels, as well as stable operation of the tracked traveling mechanism. The buffer structure absorbs and buffers impact forces when the track travels over uneven surfaces, ensuring the smooth operation of the tracked traveling mechanism and reducing the impact of vibration on the vehicle body 2 and its components.

[0048] For more specific details, please refer to Figure 7 The diagram shows the installation structure of the drive locking structure. As can be seen, the drive locking structure includes an electric telescopic cylinder 15, which is installed in the placement slot of the beam arm 22. The telescopic shaft of the electric telescopic cylinder 15 is concentrically and fixedly connected to one end of the sliding sleeve 26, providing power for the movement of the sliding sleeve 26. A sliding rod 28 passes through the sliding sleeve 26, forming a sliding connection. The sliding rod 28 can slide along the axial direction of the sliding sleeve 26. One end of the sliding rod 28 is fixedly connected to the pressing block 27. As the sliding rod 28 moves, the pressing block 27 can lock the first drive wheel 23. A first buffer spring 25 is sleeved on the sliding rod 28, and both ends of the first buffer spring 25 are connected to the sliding sleeve 26 and the pressing block 27 respectively. The first buffer spring 25 provides a buffering effect during the locking process of the first drive wheel 23 by the pressing block 27, reducing rigid impact.

[0049] For more specific details, please refer to Figure 8The diagram shows the installation structure of the buffer structure. As can be seen, the buffer structure includes a first connecting rod 29. One end of the first connecting rod 29 is hinged to the beam arm 22, allowing it to rotate relative to the beam arm 22 around the hinge point. The other end of the first connecting rod 29 is fixedly connected to the shaft of the bottom tension wheel 24, transmitting the supporting force of the beam arm 22 to the bottom tension wheel 24. One end of the second connecting rod 30 is hinged to the beam arm 22, allowing it to rotate relative to the beam arm 22. The other end of the second connecting rod 30 is hinged to the shaft of the bottom tension wheel 24, allowing it to rotate around the shaft of the bottom tension wheel 24. The second connecting rod 30 and the first connecting rod 29 work together to support and connect the bottom tension wheel 24, making the installation of the bottom tension wheel 24 more stable. The second buffer spring 31 is sleeved outside the second connecting rod 30. The two ends of the second buffer spring 31 are connected to the beam arm 22 and the second connecting rod 30 respectively. When the bottom tension wheel 24 encounters bumps or vibrations, the second buffer spring 31 can absorb and buffer the impact force through its own elastic deformation, reduce the degree of vibration transmitted to the beam arm 22 and the entire track walking mechanism, and ensure the smooth operation of the device.

[0050] Based on the above structure and connections, the overall working principle of the manure removal device in a livestock farm is as follows:

[0051] Step 1: The drive motor drives the first and second drive wheels 19 to rotate, which mesh with the track chain 18 to drive its cyclical movement, thus enabling the vehicle body 2 to move. The top tension wheel 20 and the bottom tension wheel 24 support the track chain 18 and maintain its tension. The buffer structure absorbs the impact force on uneven road surfaces to ensure smooth movement. In the case of a slope, the drive locking structure can lock the first drive wheel 23 to assist in parking.

[0052] Step 2: The operator operates from the cab 3, and the radar 1 detects the surrounding environment; four electric telescopic cylinders 15 lift and lower synchronously, causing the lifting plate 12 to move, and two tilting motors 13 rotate synchronously, driving the main support arm 11 to tilt. Combined with the main support arm 11 and the auxiliary support arm 14, the front shovel is lifted and the angle is adjusted to prepare for shoveling manure.

[0053] Step 3: The scraper part 17 of the front shovel contacts the feces to complete the shoveling. The angle of the front shovel is adjusted by the mechanical connection mechanism so that the feces are transferred from the scraper part 17 to the guide part 16 and then guided by the guide part 16 to be accurately poured into the receiving end of the separation box 4 of the fecal liquid separation mechanism.

[0054] Step 4: The material containing fecal liquid slides into the cavity through the inclined slope of the receiving end of the separation box 4 and falls onto the filter frame 10; urine permeates through the filter holes and remains at the bottom of the box, while feces are intercepted, completing the initial separation; when urine needs to be discharged, the solenoid valve 8 opens and the urine is discharged through the outlet, otherwise it is temporarily stored; when feces need to be discharged, the servo motor 5 drives the manure baffle 6 to flip and open the manure outlet, and the feces slide down the inclined slope of the filter frame 10 by gravity, and are transported to the designated position by the guide plate, after which the manure baffle 6 is reset.

[0055] This invention enables the device to move via a tracked walking mechanism, with the front shovel working in conjunction with a mechanical connection mechanism to scoop up and guide the manure, and the manure-liquid separation mechanism to automatically separate manure and urine. The overall process reduces manual intervention and improves manure removal efficiency. This invention utilizes the filter hole structure design of the filter frame 10 inside the separation box 4 to allow urine from cattle and sheep manure to permeate through the filter holes and remain at the bottom of the separation box 4 under gravity. The manure is trapped, and the solenoid valve 8 installed at the urine outlet 9 can be precisely controlled by the control system. When discharge is needed, the solenoid valve 8 is opened to allow urine to be discharged through the outlet; when discharge is not needed, it is closed to temporarily store the urine, achieving automated management. At the same time, the urine outlet 9 at the bottom of the separation box 4 is designed so that the urine can be directly connected to the collection device or treatment system, reducing retention time, reducing odor and pollution risks, facilitating subsequent fertilizer or harmless treatment, and improving resource utilization value. Furthermore, the urine separation function is integrated with the main body of the separation box 4, and the filter frame 10, solenoid valve 8, and other components are compactly arranged and independent of the manure discharge path, avoiding manure residue blockage or interference, ensuring continuous and stable operation of the separation process, and reducing maintenance costs. Compared with the prior art, this invention solves the problem of how to separate cattle and sheep manure from urine.

[0056] Example 2: In manure removal operations at a livestock farm, a filtration structure can achieve initial separation of feces and urine. However, compared to the highly viscous manure, the amount of residual urine in the feces increases. How to enhance the separation effect of feces and urine and achieve more thorough solid-liquid separation has become an urgent technical problem to be solved. To address this, this example, based on Example 1, further installs a squeezing mechanism on the separation box 4. This squeezing mechanism is used to squeeze the manure on the filter frame 10. The specific structure of the squeezing mechanism is as follows.

[0057] refer to Figures 9-10 ,in Figure 9 The diagram shown is a schematic of the installation structure of the extrusion mechanism. Figure 10 The diagram shows the installation structure of the compression mechanism after the separation box 4 has been cut open. As can be seen, a cover plate 32 is installed inside the separation box 4. The cover plate 32 is slidably connected to the inner wall of the separation box 4, and a third buffer spring (not shown in the diagram) connects the cover plate 32 and the separation box 4. When the guide section 16 of the front shovel is opposite the manure inlet 33 (meaning the manure has been discharged), the descent action of the mechanical connection mechanism drives the front shovel to descend, thereby causing the guide section 16 to push the cover plate 32 downward. The descending cover plate 32 forms a compression engagement with the filter frame 10 inside the separation box 4: when the cover plate 32 descends, it compresses the manure falling on the filter frame 10 towards the filter frame 10, using the filter holes of the filter frame 10 to achieve urine permeation separation, while the manure is retained. The compression enhances the manure separation effect, allowing urine to be filtered out more fully and reducing the water content of the manure. The front shovel and the mechanical connection mechanism are linked, so that the guide section 16 of the front shovel can serve as both a manure conveying channel and a driving source for the descent of the cover plate 32.

[0058] During the process of the cover plate 32 squeezing the fecal liquid in the separation box 4, in order to prevent excessive urine from being discharged from the inlet 33 (a small amount of urine being discharged from the inlet 33 is permissible), the following optimization scheme for the squeezing mechanism is proposed: Figure 11 The diagram shows the connection of the blocking block 34. The extrusion mechanism also includes the blocking block 34, which is fixed to the sloping surface of the receiving end. The top of the blocking block 34 is opposite to the manure inlet 33. When the cover plate 32 is pressed down, the blocking block 34 can contact the manure inlet 33 and block it.

[0059] Example 3: In manure removal operations at a livestock farm, to improve the overall efficiency of the process, urine needs to be quickly squeezed out of the feces. To address the problem of how to accelerate the squeezing of urine out of the feces, this example further designs a rapid lifting mechanism, referring to... Figure 12 The schematic diagram of the instantaneous lifting mechanism installation structure shown is based on Embodiment 1. This embodiment also incorporates a squeezing mechanism, but differs slightly from the squeezing mechanism in Embodiment 2 in that the fixed connection between the filter frame 10 and the separation box 4 in Embodiment 2 is replaced with a sliding connection (the other components and connections of the squeezing mechanism are the same as those in Embodiment 2, and will not be repeated here). This instantaneous lifting mechanism is connected to the filter frame 10, causing the filter frame 10 to move upward instantaneously. This sudden displacement change creates an impact and squeeze on the feces, accelerating urine filtration and optimizing fecal-liquid separation efficiency. The specific structure of the instantaneous lifting mechanism is as follows.

[0060] refer to Figures 13-14 and combined Figure 12 ,in Figure 13 The diagram shown is a partial installation structure schematic of the instantaneous lifting mechanism, while Figure 14The diagram shows a partial three-dimensional representation of the instantaneous lifting mechanism. As can be seen, the mechanism includes a threaded rod 35. The top of the threaded rod 35 is threadedly connected to the cover plate 32 (the threaded rod 35 only forms threads at its top), and the bottom of the threaded rod 35 is rotatably connected to the bottom of the separation box 4. When the cover plate 32 moves downward, the threaded joint converts the linear motion into the rotational motion of the threaded rod 35; that is, the downward movement of the cover plate 32 drives the threaded rod 35 to rotate around its own axis. The threaded rod 35 can movably pass through the filter frame 10. A transverse arc-shaped groove 41 is provided on the threaded rod 35, which, together with the vertical groove 36 on the filter frame 10, forms a "guide groove" used to guide the movement of the first arc-shaped block 40 and the second arc-shaped block 39, thereby controlling the instantaneous upward movement of the filter frame 10. The first arc-shaped block 40 is slidably connected to the bottom of the arc-shaped groove 41 and can slide along the arc of the groove 41. The first arc-shaped block 40 and the second arc-shaped block 39 are connected by a fourth buffer spring 38. The second arc-shaped block 39 is installed on the connecting arm 37, which is fixed to the filter frame 10, so that the second arc-shaped block 39 moves synchronously with the filter frame 10; the second arc-shaped block 39 can move within the arc-shaped groove 41 and the vertical groove 36. At the same time, it is limited that when the first arc-shaped block 40 and the second arc-shaped block 39 are placed in the arc-shaped groove 41, the fourth buffer spring 38 is in a compressed state, storing elastic potential energy, and at this time the filter frame 10 is in the initial low position. When the cover plate 32 moves down, it causes the threaded rod 35 to rotate. Guided by the trajectory of the guide groove, the first arc block 40 and the second arc block 39 move to the junction of the arc groove 41 and the vertical groove 36. The second arc block 39 moves upward along the vertical groove 36, causing the filter frame 10 to move upward synchronously and instantaneously. During this process, the fourth buffer spring 38 releases the compressive potential energy, assisting the filter frame 10 to move upward quickly. The sudden displacement change creates an impact and squeeze on the feces, accelerating the filtration of urine. At the same time, when the second arc block 39 is opposite to the vertical groove 36, the block 34 simultaneously seals the inlet 33 to prevent the feces from overflowing during the squeezing process.

[0061] Based on the above structure and connection relationships, the working principle of the instantaneous lifting mechanism is as follows:

[0062] First, before the instantaneous lifting mechanism is used, the first arc-shaped block 40 and the second arc-shaped block 39 are located in the arc-shaped groove 41 of the threaded rod 35, the fourth buffer spring 38 is compressed, the filter frame 10 is in the initial low position, and the inlet 33 is not blocked. Then, as the cover plate 32 moves down, the threaded pair converts its linear motion into the rotation of the threaded rod 35, guiding the first arc-shaped block 40 and the second arc-shaped block 39 to slide along the arc-shaped groove 41; once the two arc-shaped blocks move to the junction of the arc-shaped groove 41 and the vertical groove 36, the second arc-shaped block 39 moves up along the vertical groove 36, causing the filter frame 10 to move up instantly. The fourth buffer spring 38 releases potential energy to assist in impacting and squeezing the feces, accelerating the filtration of urine; when the second arc-shaped block 39 moves up, the block 34 simultaneously blocks the inlet 33 to prevent fecal overflow. Finally, before the cover plate 32 moves upward, use external force (such as inserting a wooden stick from the manure inlet 33, etc.) to push the filter frame 10 downward to reset. At this time, the first arc block 40 compresses the fourth spring until the height of the first arc block 40 and the second arc block 39 is the same as the arc groove 41. The cover plate 32 moves upward to reverse the threaded rod 35, and the arc block resets, ready for the next operation.

[0063] The present invention, by setting up an instantaneous lifting mechanism, has the following beneficial effects:

[0064] This invention accelerates the separation efficiency of urine from highly viscous fecal matter by creating an impact compression effect through the instantaneous upward movement of the filter frame 10. The linear motion of the cover plate 32 is converted into the instantaneous lifting action of the filter frame 10 using the cooperation of the threaded rod 35, the arc-shaped groove 41, and the buffer spring, resulting in high kinetic energy conversion efficiency. Simultaneously, the inlet 33 is sealed during compression to prevent fecal matter overflow and ensure a tight seal during the separation process. Compared to simple compression, impact separation results in lower water content in the feces, improving the thoroughness of fecal matter separation.

[0065] Example 4: In a farm operation scenario, existing farm access roads (such as...) Figure 15 This diagram illustrates an existing farm passageway, including two rain shields 42 with a gap 43 between them, surrounded by a mesh panel 44, and equipped with two large doors 45. When the farm manure removal device of this invention passes through, the limited height of the rain shields 42 relative to the ground poses a risk of difficulty in passage. To solve this problem, based on Embodiment 2 or Embodiment 3, this embodiment further designs a linkage mechanism connected to the cover plate 32. When the cover plate 32 descends, the linkage track drive mechanism moves upward relative to the vehicle body 2, reducing the overall height of the farm manure removal device. The specific structure of the linkage mechanism is as follows.

[0066] refer to Figures 16-18 ,in Figure 16 The diagram shown is a schematic of the installation structure of the linkage mechanism. Figure 17 The diagram shown is a partial installation structure schematic of the linkage mechanism, while Figure 18The diagram shows an exploded view of the linkage mechanism and the vehicle body 2. As can be seen from the diagram, the linkage mechanism includes a boom 46, the side of which is fixed to the cover plate 32. The top of the first toothed plate 47 is fixed to the boom 46, together forming a rigid connection structure of "cover plate 32, boom 46, and first toothed plate 47". The displacement of the cover plate 32 can be transmitted to the first toothed plate 47 through the boom 46, causing the first toothed plate 47 to move synchronously with the cover plate 32. A transmission gear 50 is rotatably connected to a support frame 48, which is fixed to the vehicle body 2, providing rotational support for the transmission gear 50. One end of the transmission gear 50 meshes with the first toothed plate 47, and the other end meshes with the second toothed plate 52, forming a "gear and toothed plate" transmission structure. The second toothed plate 52 is fixed to the suspension frame 21 of the track drive mechanism. The lifting groove 49 is provided on the vehicle body 2. The protrusion 54 on the limiting frame 51 is embedded in the adjacent slide rail 53 in the lifting groove 49. The protrusion 54 and the slide rail 53 are slidably engaged. The limiting frame 51 is fixed on the suspension frame 21. When the first toothed plate 47 moves due to the downward movement of the cover plate 32, it can drive the transmission gear 50 to rotate, thereby linking the second toothed plate 52 and the suspension frame 21 to move upward. When the suspension frame 21 is driven by the second toothed plate 52, the limiting frame 51 can slide along the slide rail 53, while constraining the suspension frame 21 to move upward relative to the vehicle body 2, ensuring the stability of the track drive mechanism's upward movement (i.e., the upward movement of the suspension frame 21 relative to the vehicle body 2 needs to be simultaneously constrained by the "gear and toothed plate" transmission structure and the sliding fit of the limiting frame 51 and the slide rail 53).

[0067] Based on the above structure and connection relationships, the working principle of the linkage mechanism is as follows:

[0068] First, when the cover plate 32 begins to descend under the push of the front shovel guide part 16, the displacement of the cover plate 32 is transmitted through the boom 46, causing the first toothed plate 47 to move down synchronously.

[0069] Then, the first toothed plate 47 rotates in sequence with the transmission gear 50, and the second toothed plate 52 moves upward synchronously (because the second toothed plate 52 is fixed to the suspension frame 21 of the track drive mechanism, the track drive mechanism moves upward synchronously); when the suspension frame 21 moves upward, the limiting frame 51 fixed to the suspension frame 21 moves upward accordingly, and the protrusion 54 slides along the slide rail 53 in the lifting groove 49 of the vehicle body 2; the track drive mechanism moves upward relative to the vehicle body 2, reducing the overall height of the manure removal device and meeting the height restriction requirements for passing through the farm road.

[0070] Finally, when the cover plate 32 moves upward (such as after the manure squeezing action is completed or after passing through the farm passage), the first toothed plate 47 moves upward with the cover plate 32, driving the transmission gear 50 to rotate in the opposite direction, causing the second toothed plate 52 and the suspension frame 21 to fall back; the protrusion 54 of the limit frame 51 slides down along the slide rail 53, and the track drive mechanism gradually resets to the initial height, waiting for the next linkage trigger.

[0071] The present invention, by setting up a linkage mechanism, has the following beneficial effects:

[0072] This invention lowers the overall height of the manure removal device by lowering the cover plate 32 in conjunction with the upward movement of the track drive mechanism, allowing it to pass smoothly through the farm passageway. Utilizing the transmission of gears and toothed plates, as well as the cooperation between the limiting frame 51 and the slide rail 53, the displacement of the cover plate 32 is converted into the upward movement of the track drive mechanism, resulting in a compact structure and reliable linkage. Furthermore, in conjunction with the squeezing mechanism, the device height is adjusted synchronously when the cover plate 32 lowers to squeeze the manure, without affecting the manure removal process and improving overall operational efficiency.
