Description

[0002] With the large-scale development of animal husbandry, the efficient treatment of cattle and sheep manure on farms has become a key issue for environmental protection and resource recycling. Currently, common cleaning equipment and methods for cattle and sheep manure removal on farms focus on removing the manure en bloc, failing to effectively separate it from urine. This mixing of manure and urine not only increases the difficulty and transportation costs of cleaning, but also prevents the separate recycling of useful components in urine, resulting in a waste of resources. Furthermore, mixed manure and urine are prone to bacterial growth, hindering subsequent treatment and environmental protection. Related prior art for farm manure removal is disclosed in the Chinese Patent Library (CN117016433A, CN118120635B).

[0034] In order to clearly understand the technical solution of the present application, a farm manure cleaning device provided by the present application will be described in detail below with reference to specific embodiments and drawings.

[0035] The terms used in the following examples are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and claims of this application, the singular expressions "a," "an," "above," "the," and "this" are intended to include expressions such as "one or more," unless the context clearly indicates otherwise. It should also be understood that in the following examples of this application, "at least one," "one or more" refer to one, two, or more than two.

[0036] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "one embodiment," "some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in 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 "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0037] Example 1: This example provides a farm manure cleaning device, referring to Figure 1 , which shows a schematic diagram of the three-dimensional structure of a manure cleaning device for a farm. As can be seen from the figure, the device includes a body 2, which is the basic bearing structure of the device. The crawler walking mechanism is installed at the bottom of the body 2, which is used to drive the equipment to move. It is the execution component of the body 2 to realize the movement function; the cockpit 3 is arranged in the upper area of ​​the body 2, forming an inclusive connection with the body 2, providing an operating space for the operator; the radar 1 is installed at the front position of the top of the body 2, and is fixedly connected to the body 2 through an adaptive mounting seat and other components for detecting the surrounding environment; the manure liquid separation mechanism is located at the rear of the top of the body 2 to realize the manure liquid separation function; the front shovel is connected to the front of the body 2 through a mechanical connection mechanism, which can realize shoveling, loading and other actions.

[0038] Specifically, refer to Figure 2-3 ,in, Figure 2 The figure shows the installation structure diagram of the manure liquid separation mechanism. Figure 3The figure shows a schematic diagram of the structure of the feces-liquid separation mechanism. As can be seen from the above two figures, the feces-liquid separation mechanism includes a separation box 4. The separation box 4 serves as a basic bearing unit. The material receiving end and the storage end of the separation box 4 are different functional areas integrally formed in the box body. The material receiving end is provided with a slope structure for guiding the material to enter; the storage end is used for temporarily storing feces and urine. The material receiving end and the storage end together constitute the main volume of the separation box 4. The separation box 4 passes through the rear of the vehicle body 2 and is fixedly connected to the vehicle body 2. The top of the separation box 4 is placed above the vehicle body 2, and the bottom of the separation box 4 is placed below the vehicle body 2. The filter frame 10 is installed on the inner side of the separation box 4, and the filter frame 10 relies on its own filter pore structure to achieve the separation function of feces and urine. The servo 5 is mounted on the outside of the separation box 4. The servo 5 is connected to the manure retaining plate 6 via a rotating shaft. The rotating shaft is rotatably connected to the manure outlet, which can be used to discharge manure. After receiving the control signal, the servo 5 can drive the manure retaining plate 6 to flip around the rotating shaft to achieve the blocking or discharge action of the manure outlet. The manure guide plate 7 is mounted on the outer end of the separation box 4 and placed below the manure outlet to guide the separated manure to move along a preset path and assist in transporting the manure to a designated location. The filter rack 10 is sloped, and the bottom of the filter rack 10 is opposite to the manure outlet. The urine outlet 9 is a liquid discharge port opened at the bottom of the separation box 4. The solenoid valve 8 is mounted on the urine outlet 9. The solenoid valve 8 controls the opening and closing of the urine outlet 9 to achieve discharge control of the separated urine. That is, when the solenoid valve 8 is open, the separated urine can be discharged from the separation box 4 through the urine outlet 9. When it is closed, the separated urine is temporarily stored in the separation box 4.

[0039] Combined with the above structure and connection relationship, the working principle of the manure liquid separation mechanism is as follows: In the first step, the material containing liquid manure (cow and sheep manure) is transported to the receiving end of the separation box 4. The slope structure of the receiving end guides the material to slide into the main cavity of the separation box 4 to achieve preliminary convergence of the material.

[0040] In the second step, the material enters the separation box 4 and falls onto the filter frame 10 installed inside the box. Due to the filter pore structure of the filter frame 10, urine permeates the filter pores due to gravity and remains at the bottom of the separation box 4; feces is trapped on the filter frame 10, completing the initial separation of feces and liquid.

[0041] In the third step, when the separated urine needs to be discharged, the control system issues a command to trigger the opening of solenoid valve 8 installed at urine outlet 9. The urine temporarily stored at the bottom of separation box 4 is discharged from separation box 4 through urine outlet 9. If discharge is not required, solenoid valve 8 remains closed, and the urine continues to remain in separation box 4.

[0042] Fourth, when the filtered feces need to be discharged, the servo 5 receives a control signal and drives the manure retaining plate 6 to rotate about its axis, opening the manure outlet of the separation box 4. The feces on the filter frame 10 slides down due to gravity and the slope, falling through the manure outlet onto the manure guide plate 7 below. It then follows the guide plate's pre-set path and is transported to a designated processing location (such as a manure truck or fermentation unit). After the feces are discharged, the servo 5 drives the manure retaining plate 6 back to its original position, resealing the manure outlet and preparing for the next round of separation.

[0043] Specifically, refer to Figure 4 , which shows a schematic diagram of the assembly structure of the mechanical connection mechanism. As can be seen from the figure, the mechanical connection mechanism includes an electric telescopic cylinder 15. In this embodiment, there are four electric telescopic cylinders 15. The four electric telescopic cylinders 15 serve as basic support components and are all fixedly installed in the assembly groove at the front of the vehicle body 2. The telescopic ends of the electric telescopic cylinders 15 are connected to the lifting plate 12. Through the synchronous lifting and lowering action of the four electric telescopic cylinders 15, the lifting plate 12 can be driven to achieve up and down displacement. The flip motor 13 is installed on the lifting plate 12 (in this embodiment, there are two flip motors 13). The output shafts of the two flip motors 13 are respectively fixedly connected to the two ends of the pin shaft, and the pin shaft is fixedly connected to the main support arm 11. Through the synchronous rotation of the two flip motors 13, the main support arm 11 can be driven to perform a flipping action, thereby achieving the angle adjustment 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 the front shovel, and transmit the power of the flip motor 13 and the lifting action of the electric telescopic cylinder 15 to the front shovel, thereby realizing the lifting and flipping operations of the front shovel.

[0044] Specifically, refer to Figure 5 The diagram shows the front shovel's individual structure. As can be seen, the front shovel consists of a scraper section 17 and a guide section 16, which are mechanically connected (e.g., welded or bolted) to form a complete front shovel. The scraper section 17, as the end that directly contacts 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 dimensions at the connection between the scraper section 17 and the guide section 16 are designed to taper, decreasing from large to small along the material conveying direction (not shown in the diagram). Once the scraper section 17 contacts and scoops up feces, the overall angle of the front shovel can be adjusted using a mechanical connection mechanism. The purpose of adjusting the angle is to ensure a smooth transition of the feces scooped up by the scraper section 17 to the guide section 16. The guide section 16 then guides the feces into the receiving end of the separation box 4, effectively transitioning from scooping to guiding.

[0045] Specifically, refer to Figure 6, shows a schematic diagram of the three-dimensional structure of the crawler travel mechanism. As can be seen from the figure, the crawler travel 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, which serves to connect and carry other components and transmit force. The first drive wheel 23 and the second drive wheel 19 are transferred to 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. As the power output wheel of the crawler travel mechanism, it engages with the crawler chain 18 to drive the crawler chain 18 to move, thereby driving the entire crawler travel mechanism to move. 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, thereby assisting the vehicle body 2 in maintaining its position under conditions such as slopes or achieving a specific parking function. The crawler chain 18 loops around the first and second drive wheels 23, 19, and the top and bottom tensioning wheels 20, 24. The crawler chain 18 meshes with the first and second drive wheels 23, 19, driving the first and second drive wheels 23, 19 to circulate, enabling the crawler mechanism to travel. The top tensioning wheels 20 (three in this embodiment) are fixed to the top of the beam arm 22, while the bottom tensioning wheels 24 (five in this embodiment) are attached to the bottom of the beam arm 22 via a buffer structure. The top and bottom tensioning wheels 20, 24 support the crawler chain 18, maintaining a certain tension. This ensures effective engagement between the crawler chain 18 and the drive wheels, and stable operation of the crawler mechanism. The buffer structure absorbs and cushions impact forces when the crawler track travels over uneven surfaces, ensuring smooth operation of the crawler mechanism and reducing the impact of vibration on the vehicle body 2 and its components.

[0046] For more specific reference, see Figure 7 , shows a schematic diagram of the installation structure of the drive locking structure. As can be seen from the figure, the drive locking structure includes an electric telescopic cylinder 15, which is installed in the placement groove of the beam arm 22. The telescopic shaft of the electric telescopic cylinder 15 is concentrically fixedly connected to one end of the sliding sleeve 26, providing a power source for the movement of the sliding sleeve 26. The sliding rod 28 is inserted into the sliding sleeve 26, and the two form a sliding connection. The sliding rod 28 can slide axially along the sliding sleeve 26. One end of the sliding rod 28 is fixedly connected to the pressure block 27. As the sliding rod 28 moves, the pressure block 27 can form a locking action on the first drive wheel 23. The first buffer spring 25 is mounted on the sliding rod 28, and the two ends of the first buffer spring 25 are respectively connected to the sliding sleeve 26 and the pressure block 27. The first buffer spring 25 is used to provide a buffering effect and reduce rigid impact during the process of the pressure block 27 locking the first drive wheel 23.

[0047] For more specific reference, see Figure 8, shows a schematic diagram of the installation structure of the buffer structure. As can be seen from the figure, the buffer structure includes a first connecting rod 29, one end of which is connected to the beam arm 22 by a hinged connection and can 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 tensioning wheel 24, transmitting the supporting force of the beam arm 22 to the bottom tensioning wheel 24. One end of the second connecting rod 30 is hinged to the beam arm 22 and can rotate relative to the beam arm 22; the other end of the second connecting rod 30 is hinged to the shaft of the bottom tensioning wheel 24 and can rotate around the shaft of the bottom tensioning wheel 24. The second connecting rod 30 cooperates with the first connecting rod 29 to jointly support and connect the bottom tensioning wheel 24, making the installation of the bottom tensioning wheel 24 more stable. The second buffer spring 31 is mounted outside the second connecting rod 30, and the two ends of the second buffer spring 31 are respectively connected to the beam arm 22 and the second connecting rod 30. When the bottom tensioning wheel 24 encounters bumps and vibrations, the second buffer spring 31 can absorb and buffer the impact force through its own elastic deformation, thereby reducing the degree of vibration transmitted to the beam arm 22 and the entire crawler walking mechanism, thereby ensuring the smooth operation of the device.

[0048] Combined with the above structure and connection relationship, the overall working mode of the farm manure cleaning device is as follows: In step 1, the driving motor drives the first and second driving wheels 19 to rotate, engages with the track chain 18 and drives its circular motion to realize the movement of the vehicle body 2; the top tensioning wheel 20 and the bottom tensioning wheel 24 support the track chain 18 and maintain the tension, and the buffer structure absorbs the impact force on uneven roads to ensure smooth movement; when working on a slope, the drive locking structure can lock the first driving wheel 23 to assist parking.

[0049] Step 2: The operator operates in the cockpit 3, and the radar 1 detects the surrounding environment; the four electric telescopic cylinders 15 rise and fall synchronously to drive the lifting plate 12 to move, and the two flip motors 13 rotate synchronously to drive the main support arm 11 to flip. Combined with the main support arm 11 and the auxiliary support arm 14, the front shovel is raised and lowered and the angle is adjusted to prepare for shoveling manure.

[0050] Step 3: The scraping part 17 of the front shovel contacts the feces and completes the scooping. The angle of the front shovel is adjusted by the mechanical connection mechanism so that the feces transitions from the scraping part 17 to the guide part 16, and is guided by the guide part 16 to be accurately poured into the receiving end of the separation box 4 of the feces-liquid separation mechanism.

[0051] In step 4, the feces-containing liquid material slides into the cavity through the slope of the receiving end of the separation box 4 and falls onto the filter rack 10; the urine permeates the filter holes and remains at the bottom of the box, and the feces are intercepted, completing the preliminary separation; when urine needs to be discharged, the solenoid valve 8 is opened and the urine is discharged through the outlet, otherwise it is temporarily stored; when feces need to be discharged, the steering gear 5 drives the feces retaining plate 6 to flip open the feces outlet, and the feces slides down the slope of the filter rack 10 by gravity and is transported to the designated position through the guide plate, and then the feces retaining plate 6 is reset.

[0052] The present invention realizes the movement of the device through the crawler walking mechanism, the front shovel cooperates with the mechanical connection mechanism to complete the feces scooping and material guiding, and the feces-liquid separation mechanism automatically realizes feces and urine separation. The overall process reduces manual intervention and improves feces cleaning efficiency. The present invention adopts the filter hole structure design of the filter frame 10 in the separation box 4, and utilizes gravity to make the urine in the cattle and sheep manure penetrate the filter holes and remain at the bottom of the separation box 4, and the feces are intercepted. The solenoid valve 8 installed at the urine outlet 9 can be accurately controlled to be on and off by the control system. When discharge is required, the solenoid valve 8 is opened to discharge the urine through the outlet, and when discharge is not required, it is closed to temporarily store the urine, thereby realizing 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 the retention time, reducing the risk of odor and pollution, facilitating subsequent fertilizer or harmless treatment, and improving the resource utilization value. 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 feces discharge path, avoiding blockage or interference of feces residue, ensuring the continuous and stable operation of the separation process, and reducing maintenance costs. Compared with the prior art, the present invention solves the problem of how to separate cattle and sheep manure from urine.

[0053] In Example 2, during manure cleaning operations on livestock farms, a filtration structure can achieve a preliminary separation of feces and urine. However, with highly viscous manure, the amount of urine remaining in the manure increases. Improving the separation of feces and urine and achieving a more thorough solid-liquid separation has become a pressing technical challenge. To address this issue, this example, based on Example 1, further incorporates a squeezing mechanism on the separation box 4. This mechanism is used to squeeze the manure from the filter rack 10. The specific structure of the squeezing mechanism is as follows.

[0054] refer to Figure 9-10 ,in Figure 9 The figure shows the installation structure diagram of the extrusion mechanism. Figure 10 The diagram shows the installation structure of the extrusion mechanism after a section of the separation box 4. As can be seen, a cover plate 32 is installed within 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 is connected between the cover plate 32 and the separation box 4 (the third buffer spring is not shown in the diagram). When the guide portion 16 of the front shovel is aligned with the manure inlet 33 (at this point, the manure has been discharged), the mechanical connection mechanism lowers the front shovel, causing the guide portion 16 to push the cover plate 32 downward. The downward movement of the cover plate 32 forms a compression fit with the filter frame 10 within the separation box 4. As the cover plate 32 moves downward, it squeezes the manure on the filter frame 10 toward the filter frame 10, achieving urine permeation separation through the filter pores of the filter frame 10 while retaining the feces. This compression enhances the manure separation effect, allowing urine to be filtered more thoroughly and reducing the moisture content of the feces. The front shovel is linked to the mechanical connection mechanism, allowing the guide portion 16 of the front shovel to serve as both a manure conveying channel and a driving force for the cover plate 32 to descend.

[0055] When the cover 32 squeezes the feces in the separation box 4, in order to prevent excessive urine from being discharged from the feces inlet 33 (a small amount of urine is allowed to be discharged from the feces inlet 33); for this reason, as an optimization scheme of the squeezing mechanism, refer to Figure 11 The block 34 is shown in the figure. The extrusion mechanism also includes the block 34, which is fixed to the sloped surface of the receiving end. The top of the block 34 faces the feces inlet 33. When the cover plate 32 is pressed down, the block 34 can contact the feces inlet 33 and form a blockage thereon.

[0056] Example 3: In the feces cleaning operation of the farm, in order to improve the efficiency of the overall feces cleaning process, urine needs to be squeezed out of the feces quickly. In order to solve the problem of how to speed up the squeezing of urine from the feces, this embodiment further designs a sudden rise mechanism. Figure 12 The schematic diagram of the instantaneous lift mechanism installation structure shows a structure that, based on Example 1, also incorporates a squeezing mechanism. However, this embodiment differs slightly from the squeezing mechanism of Example 2 in that the fixed connection between the filter frame 10 and the separation box 4 in Example 2 is replaced with a sliding connection (the other components and connections of the squeezing mechanism are the same as those of Example 2 and will not be further described here). This instantaneous lift mechanism is connected to the filter frame 10 and causes the filter frame 10 to move upward instantaneously. This sudden change in displacement creates an impact squeeze on the feces, accelerating urine filtration and optimizing fecal-liquid separation efficiency. The specific structure of the instantaneous lift mechanism is as follows.

[0057] refer to Figure 13-14 Combined with Figure 12 ,in Figure 13 The diagram shows the partial installation structure of the instantaneous rise mechanism. Figure 14A partial perspective schematic diagram of the instantaneous lift mechanism is shown. As can be seen, the instantaneous lift mechanism comprises a threaded rod 35, the top of which is threadedly connected to the cover plate 32 (the threads are formed only at the top), and the bottom of which is pivotally connected to the bottom of the separation chamber 4. When the cover plate 32 moves downward, the threaded pair converts the linear motion of the threaded rod 35 into rotational motion. Specifically, the downward movement of the cover plate 32 drives the threaded rod 35 to rotate about its own axis. The threaded rod 35 is movable through the filter frame 10. A transverse arcuate groove 41 is provided on the threaded rod 35, which, together with the vertical groove 36 on the filter frame 10, forms a "guide chute" to guide the movement of the first and second arcuate blocks 40, 39, thereby controlling the instantaneous upward movement of the filter frame 10. The first arcuate block 40 is slidably connected to the bottom of the arcuate groove 41 and can slide in the arcuate direction of the arcuate groove 41. The first and second arcuate blocks 40, 39 are connected by a fourth buffer spring 38. The second curved block 39 is mounted on the connecting arm 37, which is fixed to the filter frame 10, allowing the second curved block 39 to move synchronously with the filter frame 10. The second curved block 39 can move within the curved groove 41 and the vertical groove 36. Furthermore, it is specified that when the first and second curved blocks 40 and 39 are positioned within the curved groove 41, the fourth buffer spring 38 is compressed, storing elastic potential energy, and the filter frame 10 is initially in a low position. When the cover plate 32 moves downward, the threaded rod 35 rotates. Guided by the trajectory of the guide groove, the first arc block 40 and the second arc block 39 move to the intersection of the arc groove 41 and the vertical groove 36. The second arc block 39 moves upward along the vertical groove 36, driving the filter frame 10 to move upward synchronously and instantly; during this process, the fourth buffer spring 38 releases the compression potential energy, assisting the filter frame 10 to move upward quickly, and using the sudden displacement change to form an impact squeeze on the feces, thereby accelerating the filtration of urine; at the same time, when the second arc block 39 is opposite to the vertical groove 36, the blocking block 34 synchronously blocks the fecal inlet 33 to prevent fecal liquid from overflowing during the squeezing process.

[0058] Combined with the above structure and connection relationship, the working principle of the instantaneous rise mechanism is as follows: First, before the instantaneous lifting mechanism is used, the first arc block 40 and the second arc block 39 are located in the arc 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 feces inlet 33 is unblocked. Then, when the cover plate 32 moves downward, the threaded pair converts its linear motion into rotation of the threaded rod 35, guiding the first arc block 40 and the second arc block 39 to slide along the arc groove 41; once the two arc blocks move to the intersection of the arc groove 41 and the vertical groove 36, the second arc block 39 moves upward along the vertical groove 36, driving the filter frame 10 to move upward instantly, and the fourth buffer spring 38 releases potential energy to assist, impacting and squeezing feces, accelerating urine filtration; when the second arc block 39 moves upward, the blocking block 34 simultaneously blocks the feces inlet 33 to prevent fecal liquid from overflowing. Finally, before the cover plate 32 moves upward, an external force (such as inserting a wooden stick from the feces inlet 33) is first used 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 are the same as the arc groove 41. The cover plate 32 moves upward to reverse the threaded rod 35, and the arc block is reset to prepare for the next operation.

[0059] The present invention provides the instantaneous lifting mechanism, which has the following beneficial effects: The present invention accelerates the separation efficiency of urine from high-viscosity fecal liquid by instantly moving the filter frame 10 upward to form impact extrusion; utilizes the cooperation of the threaded rod 35, the arc groove 41 and the buffer spring to convert the linear motion of the cover plate 32 into an instantaneous rising motion of the filter frame 10, with high kinetic energy conversion efficiency; during extrusion, the fecal inlet 33 is simultaneously blocked to prevent fecal liquid from overflowing and ensure the sealing of the separation process; compared with simple extrusion, impact separation can reduce the moisture content of feces and improve the thoroughness of fecal liquid separation.

[0060] Example 4, in the farm operation scene, the existing farm road (such as Figure 15 The figure shows an existing farm passage, which includes two rain shields 42 with a gap 43 between them, surrounded by mesh 44 on the sides, and equipped with two gates 45). When the farm manure cleaning device of the present invention passes through, it faces the risk of difficulty in passing due to the limited height between the rain shield 42 and the ground. To solve this problem, based on Example 2 or Example 3, this embodiment further designs a linkage mechanism, which is connected to the cover plate 32; when the cover plate 32 descends, the linkage crawler drive mechanism moves upward relative to the vehicle body 2, thereby lowering the overall height of the farm manure cleaning device. The specific structure of the linkage mechanism is as follows.

[0061] refer to Figure 16-18 ,in Figure 16 The figure shows the installation structure diagram of the linkage mechanism. Figure 17 The diagram shows the partial installation structure of the linkage mechanism. Figure 18What is shown is a schematic diagram of the exploded structure of the linkage mechanism and the vehicle body 2. As can be seen from the above figure, the linkage mechanism includes a boom 46, the side of the boom 46 is fixed to the cover plate 32, and the top of the first tooth plate 47 is fixed to the boom 46, together forming a rigid connection structure of "cover plate 32, boom 46, first tooth plate 47". The displacement of the cover plate 32 can be transmitted to the first tooth plate 47 through the boom 46, so that the first tooth plate 47 moves synchronously with the cover plate 32. The transmission gear 50 is rotatably connected to the carrier frame 48, and the carrier frame 48 is fixed to the vehicle body 2 to provide rotational support for the transmission gear 50. One end of the transmission gear 50 is meshed with the first tooth plate 47, and the other end is meshed with the second tooth plate 52, together forming a "gear, tooth plate" transmission structure. The second tooth plate 52 is fixed to the suspension frame 21 of the crawler drive mechanism. A lifting slot 49 is formed in the vehicle body 2. A protrusion 54 on the limit frame 51 engages with an adjacent slideway 53 within the lifting slot 49. The protrusion 54 and the slideway 53 slide together, securing the limit frame 51 to the suspension bracket 21. When the first toothed plate 47 moves due to the downward movement of the cover plate 32, it drives the transmission gear 50 to rotate, thereby causing the second toothed plate 52 and the suspension bracket 21 to move upward. When the suspension bracket 21 is driven by the second toothed plate 52, the limit frame 51 slides along the slideway 53, simultaneously restraining the suspension bracket 21 from moving upward relative to the vehicle body 2 and ensuring the stability of the upward movement of the track drive mechanism (i.e., the upward movement of the suspension bracket 21 relative to the vehicle body 2 is simultaneously constrained by the "gear and toothed plate" transmission structure and the sliding adaptation of the limit frame 51 and the slideway 53).

[0062] Combined with the above structure and connection relationship, the working principle of the linkage mechanism is as follows: First, when the cover plate 32 is pushed by the front shovel guide part 16 and starts to descend, the displacement of the cover plate 32 is transmitted through the suspension arm 46, driving the first tooth plate 47 to move downward synchronously.

[0063] Then, the first tooth plate 47 sequentially links the transmission gear 50 to rotate, and the second tooth plate 52 moves up synchronously (because the second tooth plate 52 is fixed to the suspension frame 21 of the track drive mechanism, it moves up synchronously with the track drive mechanism); when the suspension frame 21 moves up, the limit frame 51 fixed to the suspension frame 21 moves up accordingly, and the protrusion 54 slides along the slide 53 in the lifting groove 49 of the vehicle body 2; the track drive mechanism moves up relative to the vehicle body 2, lowering the overall height of the manure cleaning device to meet the height limit requirement for passing through the farm road.

[0064] Finally, when the cover plate 32 moves up (for example, after the manure extrusion action is completed or after passing through the farm road), the first tooth plate 47 moves up with the cover plate 32, driving the transmission gear 50 to rotate in the opposite direction, driving the second tooth plate 52 and the suspension frame 21 to fall back; the protrusion 54 of the limit frame 51 slides down along the slide 53, and the crawler drive mechanism gradually returns to the initial height, waiting for the next linkage trigger.

[0065] The present invention has the following beneficial effects by setting a linkage mechanism: The present invention lowers the cover plate 32 to link the crawler drive mechanism upward, thereby lowering the overall height of the manure cleaning device so that it can pass through the farm road smoothly; utilizes the transmission of the gear and the tooth plate and the cooperation of the limit frame 51 and the slide 53 to convert the displacement of the cover plate 32 into the upward movement of the crawler drive mechanism, with a compact structure and reliable linkage; and links with the extrusion mechanism to synchronously adjust the height of the device when the cover plate 32 descends to squeeze the manure liquid, without affecting the manure cleaning process and improving the overall operation efficiency.
