Description

Technical Field

[0001] This invention relates to the field of livestock and poultry breeding, and in particular to a metabolic cage for fattening Hu sheep with an automatic manure removal function. Background Technology

[0002] In the fattening experiment of Hu sheep, accurate collection and quantitative analysis of feces and urine are necessary to precisely monitor the nutritional metabolism, feed conversion rate, and growth performance of the sheep. Existing metabolic cages have relatively simple structures, with most having fixed gaps in the bottom plate or poorly designed drainage holes, leading to the mixed collection of feces and urine. This not only affects the accuracy of the test data but also increases the difficulty of subsequent sample processing. Furthermore, the bottom plates of existing cages are mostly fixed structures, making it easy for feces and dirt to remain on the surface. Cleaning requires frequent manual disassembly or washing, which is labor-intensive. The lack of automated cleaning functions also means that human negligence may lead to untimely feces removal, easily breeding bacteria and affecting the health of the sheep.

[0003] Furthermore, the existing breeding cages have unreasonable designs regarding the size of the gaps in the bottom plate and the flatness of the surface, which can easily cause problems such as hooves getting stuck and uneven stress when the sheep stand or move, affecting the fattening effect. Therefore, this plan proposes a metabolic cage for Hu sheep fattening experiments with an automatic manure removal function. Summary of the Invention

[0004] The metabolic cage for fattening Hu sheep with automatic manure removal function proposed in this invention solves the problem of inconvenient manure cleaning and collection in existing metabolic cages.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0014] As a further improvement to the above solution, a connecting hole is provided at the end of the limiting hole away from the mounting plate, which is coaxial with the limiting hole. The connecting hole is cylindrical and its inner diameter is smaller than the center distance of the limiting hole. Two guide grooves are arrayed on the inner wall of the connecting hole. The guide groove consists of a straight groove arranged along the length of the connecting hole and an annular groove arranged around the inner circle of the connecting hole. The straight groove is located at the end of the annular groove away from the limiting hole. The linkage component includes a connecting post fixed at the end of the limiting post away from the mounting plate and guide posts fixed on the outer walls of the connecting post on both sides in the radial direction. One end of each guide post extends into the two guide grooves and slides into them.

[0015] As a further improvement to the above solution, the back of the base is provided with a discharge trough along its length, the conveyor belt is inclined and the surface of the conveyor belt is provided with a plurality of drainage holes for urine to pass through, and the lower end of the conveyor belt extends into the discharge trough.

[0016] As a further improvement to the above solution, the transmission assembly includes two transmission rollers sleeved on the inner side of the conveyor belt for driving its rotation and a transmission motor mounted on the outer wall of the base. The outer circumferences of the two transmission rollers are respectively pressed against the inner walls of both ends of the conveyor belt, and the output shaft of the transmission motor is connected to one of the transmission rollers through a coupling.

[0017] As a further improvement to the above solution, a receiving hopper is installed at the bottom of the discharge trough along its length to catch the feces output from the conveyor belt, and an outlet is opened at one end of the receiving hopper.

[0018] As a further improvement to the above solution, the bottom inner wall of the base is inclined downward toward the side where the discharge trough is provided, and a urination pipe for discharging urine from the base is provided on one side of the base.

[0019] As a further improvement to the above solution, the driving mechanism includes an adjusting screw rotatably connected to the front of the base, a transmission gear fixed to the other end of the adjusting screw, a transmission rack located on the front of the base and meshing with the transmission gear, and a driving component installed on the front of the base for driving the transmission rack to move up and down. The mounting plate is threaded onto the outer periphery of the adjusting screw, and a fixing frame for stabilizing its up and down movement is movably fitted onto the outer periphery of the transmission rack, and the fixing frame is fixedly connected to the front of the base.

[0020] As a further improvement to the above solution, the driving component includes a transmission screw rotatably connected to its front side along the length direction of the base and a driving plate threaded onto the outer periphery of the transmission screw. The front side of the driving plate is provided with a guide groove 1 arranged along its length direction. The guide groove 1 includes a first horizontal groove on top, a second horizontal groove on the bottom, and an inclined groove connecting the end of the first horizontal groove and the beginning of the second horizontal groove. A guide rod is rotatably connected to the outer wall of the transmission rack, and one end of the guide rod extends into the guide groove 1 and slides therewith.

[0021] As a further improvement to the above solution, one end of one of the transmission rollers extends to the outside of the base and is fitted with a drive wheel, and one end of the transmission screw is fitted with a driven wheel, and the driven wheel and the drive wheel are connected by a belt drive.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. A base plate assembly is installed. The rotation of the mounting shaft drives the partition to rotate, thus changing the horizontal partition to a vertical one. This facilitates the falling off of any residual manure on the top surface of the partition. After the partition returns to a horizontal position, the gap between adjacent mounting shafts is reduced, thereby increasing the comfort of the sheep living in the cage. When the partition is horizontal, its top surface is flush with the top surface of the mounting shaft, ensuring that the rotation of the mounting shaft does not affect the normal movement of the sheep in the cage.

[0024] 2. By setting a locking mechanism, the partition can be locked when it is in a horizontal state, preventing it from rotating under the trampling of sheep. In conjunction with the linkage component, after the limiting post moves to the outside of the limiting hole, the mounting shaft can be driven to rotate as the mounting plate continues to move outward, thereby laying down the horizontal partition. Conversely, as the limiting post moves into the limiting hole, the mounting shaft can be driven to reverse, thereby turning the laid-down partition back to a horizontal state. And after the limiting post enters the limiting hole, the partition is kept in a horizontal state.

[0025] 3. Excellent fecal-urine separation effect: Through the design of the partition leakage hole, the conveyor belt seepage hole and the inclined inner wall of the base, the feces and urine are effectively separated, ensuring the purity of the test sample and improving the accuracy of the test data. Moreover, in conjunction with the drive mechanism, the transmission motor drives the conveyor belt to clean up the feces and dirt, and the linkage structure drives the partition to flip, so that the residual feces and dirt on the bottom plate can be automatically dropped without manual disassembly and cleaning, reducing labor intensity and improving the automation level of fecal cleaning.

[0037] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0038] Example 1:

[0039] Please combine Figure 1 - Figure 9 The metabolic cage for fattening Hu sheep with automatic manure removal function in this embodiment includes:

[0040] The metabolic cage body includes a base 1 and a cage body 2 mounted on top of the base 1. An inlet / outlet is located on one side of the cage body 2, and a cage door 3 is hinged to the outer side of the inlet / outlet. The cage door 3 is locked to the cage body 2 by a locking mechanism. The locking mechanism includes a fixing plate 8 fixed to the outer wall of the cage door 3 away from the hinge, a fixing plate 10 fixed to the outer wall of the cage body 2 away from the hinge, and a pin 9 for locking the fixing plates 8 and 10. Both fixing plates 8 and 10 have locking holes, through which the pin 9 passes to lock the cage door 3 to the cage body 2. An inclined pedal 4 is installed at the bottom of the inlet / outlet, with an inclination angle of 30-45°. The pedal 4 facilitates the entry and exit of sheep within the cage body 2. The pin 9 allows for easy opening or locking of the cage door 3.

[0041] The base plate assembly, installed inside the base 1, is used to create a feeding space between the cage 2 and the base 1. The base plate assembly includes an installation shaft 18 rotatably connected to the inside of the base 1 along its width direction and a partition 19 fixed to one outer wall of the installation shaft 18. The top surface of the partition 19 is flush with the top surface of the installation shaft 18, and multiple feed leakage holes are provided on the top surface of the partition 19. This ensures that when the partition 19 is in a horizontal state, the top surface of the partition 19 is flush with the installation shaft 18, improving the comfort of the sheep walking on it. The width of the partition 19 is 1cm. When the partition 19 is in a horizontal state, the distance between the partition 19 and the adjacent installation shaft 18 is 0.2-0.5cm. This not only facilitates the flow of feces and urine from the gap between the partition 19 and the installation shaft 18, but also ensures that the partition 19 is not affected by the adjacent installation shaft 18 during rotation. It also prevents the installation shaft 18 from affecting the normal activities of the sheep during rotation and effectively prevents the sheep's hooves from getting stuck in the gap between the adjacent installation shaft 18 after the partition 19 is laid down.

[0042] A locking mechanism is installed on the front of the base 1 and is used to lock the mounting shaft 18 to maintain the horizontal state of the partition 19. The locking mechanism includes a mounting plate 13 on the front of the base 1 and multiple sets of limiting members fixed to one long side of the mounting plate 13. The limiting members include a limiting post 20 and a support plate 32. The limiting post 20 is a regular polygonal prism. One end of the mounting shaft 18 has a limiting hole 29 for inserting the limiting post 20. The support plate 32 cooperates with the partition 19 and is used to extend into the bottom of the partition 19 and abut against its bottom surface after the partition 19 is in a horizontal position. A linkage component is also installed on the end of the limiting post 20 away from the mounting plate 13 to drive the mounting shaft 18 to rotate during the movement of the limiting post 20 outside the limiting hole 29 and along its length. The end of the limiting hole 29 away from the mounting plate 13 has a connecting hole 30 coaxially arranged with it. The connecting hole 30 is cylindrical and its inner diameter is smaller than the center distance of the limiting hole 29. The inner wall of the connecting hole 30 is arrayed with Two guide grooves 31 are provided. Each guide groove 31 consists of a straight groove along the length of the connecting hole 30 and an annular groove surrounding the inner circle of the connecting hole 30. The straight groove is located at the end of the annular groove away from the limiting hole 29. The linkage component includes a connecting post 27 fixed to the end of the limiting post 20 away from the mounting plate 13 and guide posts 28 fixed to the outer walls of the connecting post 27 on both sides in the radial direction. One end of each guide post 28 extends into the two guide grooves 31 and slides into them. The cooperation between the guide posts 28 and the guide grooves 31 realizes the linkage between the axial movement of the limiting post 20 and the rotation of the mounting shaft 18. When the limiting post 20 moves outward, the guide post 28 slides along the straight groove to the annular groove. If it continues to move, the guide post drives the mounting shaft 18 to rotate along the annular groove, thereby realizing the flipping of the partition. The limiting post 20 with its regular polygonal prism structure cooperates with the limiting hole 29, which can effectively prevent the mounting shaft 18 from rotating in the locked state and improve the locking reliability.

[0043] The implementation principle of this embodiment is as follows: When the sheep are being fed, the partition 19 is in a horizontal state, the limiting post 20 is inserted into the limiting hole 29, and the support plate 32 abuts against the bottom of the partition 19 to achieve double locking of the partition 19. The sheep are fed on the partition 19 in the cage 2, and the feces and urine fall into the base 1 through the feed hole of the partition 19. When cleaning the feces remaining on the partition 19, the mounting plate 13 is driven to move outward, and the limiting post 20 is pulled out from the limiting hole 29. When moving further, the guide post 28 slides along the straight groove of the guide groove 2 31 to the annular groove, driving the mounting shaft 18 to rotate, so that the partition 19 is flipped to a vertical state, so that the feces on the top surface of the partition 19 slides down under the action of gravity, thus facilitating the cleaning of the feces remaining on the partition 19.

[0044] Example 2:

[0045] Combination Figure 4 - Figure 7 This embodiment, based on embodiment 1, further improves upon the following: a cleaning mechanism, installed inside the base 1, is used to collect feces and urine falling from the base plate assembly. The cleaning mechanism includes a conveyor belt 26 installed inside the base 1 and a transmission assembly installed on the base 1 to drive the conveyor belt 26 to rotate. A discharge trough 23 is provided on the back of the base 1 along its length. A receiving hopper 24, also along its length, is installed at the bottom of the discharge trough 23 to receive feces discharged from the conveyor belt 26. One end of the receiving hopper 24 has an outlet 25. A scraper 35, arranged along the width of the conveyor belt 26, is fixed inside the receiving hopper 24. The top of the scraper 35 abuts against the bottom surface of the conveyor belt 26, thereby scraping off the feces remaining on the surface of the conveyor belt 26. The conveyor belt 26 is inclined, and the conveyor belt... Multiple drainage holes are provided on the surface of the conveyor belt 26 to allow urine to pass through. One end of the conveyor belt 26 extends into the discharge trough 23. The transmission assembly includes two transmission rollers sleeved on the inner side of the conveyor belt 26 for driving its rotation and a transmission motor mounted on the outer wall of the base 1. The outer circumferences of the two transmission rollers are respectively pressed against the inner walls of both ends of the conveyor belt 26. The output shaft of the transmission motor is connected to one of the transmission rollers through a coupling. Feces falling in the feeding space land on the surface of the conveyor belt 26, urine falls into the bottom of the base 1 through the drainage holes on the conveyor belt 26, while feces remain on the surface of the conveyor belt 26, thus achieving separate collection of feces and urine. When it is necessary to collect and process the feces on the conveyor belt 26, the transmission motor is started to drive the conveyor rollers to rotate forward, thereby transporting the feces on the conveyor belt 26 into the receiving hopper 24.

[0046] Furthermore, a PLC control panel 34 connected to the drive motor is installed on the front of the base 1. Through the PLC control panel 34, the start and stop time and forward and reverse rotation duration of the drive motor can be set. After a certain time interval, the PLC control panel 34 controls the drive motor to rotate forward. After rotating forward for a certain period of time, the drive motor is driven to rotate in reverse. After one forward and reverse cycle, the drive motor enters an intermittent stop time, waiting for the next operation. This can achieve the purpose of periodically and automatically cleaning feces, improving the intelligence of feces cleaning.

[0047] A drive mechanism, mounted on the front of the base 1 and connected to the transmission assembly, is used to drive the mounting plate 13 to move along the length of the limiting post 20 when the transmission assembly is running. The drive mechanism includes an adjusting screw 14 rotatably connected to the front of the base 1, a transmission gear 15 fixed to the other end of the adjusting screw 14, a transmission rack 11 located on the front of the base 1 and meshing with the transmission gear 15, and a drive component mounted on the front of the base 1 for driving the transmission rack 11 to move up and down. The mounting plate 13 is threaded onto the outer periphery of the adjusting screw 14. A fixing frame 22 for stabilizing its up and down movement is movably fitted onto the outer periphery of the transmission rack 11, and the fixing frame 22 is fixedly connected to the front of the base 1. The drive component includes a transmission screw 12 rotatably connected to the front of the base 1 along the length of the base 1 and a drive component threaded onto the transmission rack 14. The drive plate 6 on the outer periphery of the screw 12 has a guide groove 7 on its front side, which is arranged along its length. The guide groove 7 includes a first horizontal groove 701 on the upper side, a second horizontal groove 703 on the lower side, and an inclined groove 702 connecting the end of the first horizontal groove 701 and the beginning of the second horizontal groove 703. A guide rod 33 is rotatably connected to the outer wall of the transmission rack 11. One end of the guide rod 33 extends into the guide groove 7 and slides therewith. One end of one of the transmission rollers extends to the outside of the base 1 and is fitted with a drive wheel 16. One end of the transmission screw 12 is fitted with a driven wheel 17, and the driven wheel 17 and the drive wheel 16 are connected by a belt 5. When the conveyor belt 26 rotates, the transmission roller drives the drive wheel 16 to rotate, and the drive wheel 16 is then driven by the belt 5. Driven wheel 17 and drive screw 12 rotate, drive screw 12 drives drive plate 6 to move along length direction, guide rod 33 slides from second horizontal groove 703 through inclined groove 702 to first horizontal groove 701 in guide groove 1 7, thereby driving drive rack 11 to move upward, drive rack 11 to mesh with drive gear 15, drive adjusting screw 14 to rotate forward, thereby causing mounting plate 13 to move outward, limit post 20 is pulled out from limit hole 29, when moving further, guide post 28 slides along straight groove of guide groove 2 31 to annular groove, driving connecting hole 30 and mounting shaft 18 to rotate, causing partition plate 19 to flip to vertical state, thereby causing residual fecal matter on the surface of partition plate 19 to fall onto conveyor belt 26 and be cleaned together with conveyor belt 26. After cleaning, guide rod 33... During the movement within the first horizontal groove 701 and the second horizontal groove 703, the height of the transmission rack 11 remains unchanged. The transmission motor is started in reverse, the transmission roller rotates in reverse, the conveyor belt 26 resets, and simultaneously the transmission screw 12 rotates in reverse, the drive plate 6 moves in reverse, and the guide rod 33 slides from the first horizontal groove 701 through the inclined groove 702 to the second horizontal groove 703. The transmission rack 11 moves upward, driving the adjusting screw 14 to rotate in reverse, the mounting plate 13 moves inward, and the limiting post 20 gradually inserts into the limiting hole 29. The guide post 28 slides in reverse along the annular groove of the guide groove 31 to the straight groove, driving the mounting shaft 18 to rotate in reverse, so that the partition 19 returns to a horizontal state. After the limiting post 20 is fully inserted into the limiting hole 29, the support plate 32 abuts against the bottom of the partition 19, restoring the locked state.The equipment has been returned to its feeding state.

[0048] In this embodiment, the bottom inner wall of the base 1 is inclined downward toward the side where the discharge trough 23 is provided, and a urination pipe 21 for draining urine from the base 1 is provided on one side of the base 1. The inclined bottom wall facilitates the collection of urine, which is finally discharged from the urination pipe 21.
