Description

Technical Field

[0001] This invention relates to the field of livestock breeding equipment technology, specifically to a device and method for unloading caged poultry. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] For the poultry slaughtering industry, such as the slaughter of live chickens, the current method of transporting live chickens is mostly by vehicle. Live chickens are loaded into cages from the breeding base, the cages are stacked in layers, and then placed in a regular manner on the transport vehicle and transported to the designated slaughtering plant.

[0004] Currently, chicken cages are typically arranged in multiple rows on vehicles. Some rows are aligned with the length of the vehicle, while the remaining rows are arranged perpendicular to the vehicle's length. There is currently no dedicated unloading equipment for chicken cages, requiring manual labor. This results in a high demand for manpower, high labor intensity for workers, and low work efficiency. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a caged poultry unloading device and method that can realize automatic unloading of cages, reduce the labor intensity of workers, improve work efficiency, and save manpower.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] In a first aspect, embodiments of the present invention provide a caged poultry unloading device, including a cage pushing mechanism and a conveying mechanism respectively disposed on both sides of a vehicle, wherein the cage pushing mechanism is used to push a row of cages into the conveying mechanism.

[0008] The conveying mechanism includes alternating sets of a first fixed roller group, a first lifting roller group, a second fixed roller group, and a second lifting roller group. The first lifting roller group has a first conveying component on both sides, and the second lifting roller group has a second conveying component on both sides. Both the first and second lifting roller groups are connected to the lifting mechanism. The discharge end of the first conveying component has a turning conveying component that turns toward the second conveying component. The discharge end of the second conveying component has a reversing component. The reversing component includes multiple reversing conveying rollers arranged sequentially along the conveying direction. The reversing conveying rollers are conical rollers, and the smaller end is located close to the first conveying component.

[0009] Optionally, both the first fixed roller group and the second fixed roller group include multiple fixed rollers arranged in parallel, and the fixed rollers are rotatably connected to the first fixed frame.

[0010] Optionally, both the first and second lifting roller groups include multiple lifting rollers, the lifting rollers are rotatably connected to the lifting frame, and the lifting frame is connected to the lifting mechanism.

[0011] Optionally, the lifting mechanism includes at least one lifting hydraulic cylinder, which is hinged to a fixed hydraulic cylinder, and the piston rod of the lifting hydraulic cylinder is hinged to the lifting frame. It also includes at least two connecting rods, one end of which is hinged to a fixed connecting rod, and the other end of which is hinged to the lifting frame.

[0012] Optionally, the turning conveyor assembly adopts a conveyor structure that bends 90° toward the second conveyor component, including multiple turning conveyor rollers, with both ends of the turning conveyor rollers rotatably connected to the turning frame, wherein at least one turning conveyor roller is connected to the first rotation drive mechanism, and adjacent turning conveyor rollers are connected through a transmission component.

[0013] Optionally, the outer edge of the turning frame is provided with guardrails distributed along the conveying direction.

[0014] Optionally, at least one reversing conveyor roller is connected to the second rotation drive mechanism, and adjacent reversing conveyor rollers are connected through a transmission component.

[0015] Optionally, both the first conveying component and the second transmission component adopt a chain drive mechanism.

[0016] Optionally, the cage pushing mechanism includes a cage pushing mechanism frame, and at least two cage pushing hydraulic cylinders are provided on the top of the cage pushing mechanism frame, with a pushing component fixed to the end of the piston rod of the cage pushing hydraulic cylinder.

[0017] Secondly, embodiments of the present invention provide a method for unloading caged poultry using the device described in the first aspect:

[0018] The lifting mechanism drives the first lifting roller group to rise to be level with the first fixed roller group. The cage pushing mechanism pushes a row of cages arranged along the length direction of the vehicle to the first lifting roller group. The lifting mechanism drives the first lifting roller group to descend until the cages fall on the first conveying component. The first transmission component sends the cages into the turning conveying component, and the turning conveying component sends them out.

[0019] The lifting mechanism raises the first and second lifting roller groups to be level with the first and second fixed roller groups. The cage pushing mechanism pushes a row of cages, whose length direction is perpendicular to the length direction of the vehicle, to the second lifting roller group. The lifting mechanism lowers the second lifting roller group until the cages fall into the second conveying component. The second conveying component sends the cages into the reversing conveying component. The reversing conveying component changes the cages at a set angle and sends them into the turning conveying component, which then sends them out.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The unloading device of the present invention has a cage pushing mechanism and a conveying mechanism. The cage pushing mechanism can send the cage on the vehicle into the conveying mechanism. The conveying mechanism can send the cage into the lifting roller assembly through the fixed roller assembly. The lifting roller assembly can descend to send the cage into the conveying component. The conveying component can send the cage into the turning conveying component and then send the cage out. The whole unloading process is automated, eliminating the need for manual unloading, saving manpower, improving work efficiency, and reducing the labor intensity of workers.

[0022] 2. In the unloading device of the present invention, since the cages sent out by the first conveying component and the second conveying component are arranged in different directions, if the second conveying component directly sends the cages into the turning conveying component, it cannot continue to convey them. Therefore, a reversing conveying component is provided, which sends the cages into the turning conveying component after reversing their direction by a conical roller, so that the turning conveying component can continue to convey the cages, thus meeting the automatic unloading requirements of the existing cage arrangement on the vehicle.

[0031] Example 1

[0032] This embodiment provides a device for unloading caged poultry, such as... Figures 1-3 As shown, the unloading of chicken cages includes a cage-pushing mechanism and a conveying mechanism used in conjunction. The cage-pushing mechanism is set on one side of the vehicle, and the conveying mechanism is set on the other side of the vehicle. The cage-pushing mechanism can push a row of chicken cages on the vehicle into the conveying mechanism, and the conveying mechanism conveys the pushed-in chicken cages and sends them out.

[0033] The cage pushing mechanism includes a cage pushing mechanism frame, which is a frame structure welded from multiple square steel bars.

[0034] At least two pusher hydraulic cylinders 25 are provided on the top surface of the pusher mechanism frame. In this embodiment, two pusher hydraulic cylinders 25 are provided. The height of the pusher hydraulic cylinders 25 corresponds to the height of the first layer of chicken cages on the vehicle. The piston rod ends of the two pusher hydraulic cylinders 25 are fixed with pusher components 26. The pusher components 26 include push plates fixed to the piston rod ends. The two push plates are fixed together to the side of a pusher frame. The pusher frame adopts a rectangular frame structure, and its length corresponds to the total length of a row of chicken cages.

[0035] The piston rod of the cage-pushing hydraulic cylinder 25 can extend to push the multi-layer chicken cages in the same row off the vehicle via the pusher 26.

[0036] The conveying mechanism includes a first fixed roller group, a first lifting roller group, a second fixed roller group, and a second lifting roller group arranged alternately in sequence. The first lifting roller group has a first conveying component on both sides, and the second lifting roller group has a second conveying component on both sides. A turning conveying component is provided on one side of the discharge end of the first conveying component. The conveying direction of the turning conveying component is bent towards the direction of the second conveying component. A reversing component is provided on one side of the discharge end of the second conveying component. The reversing component can change the angle of the chicken cage and send it into the turning conveying component.

[0037] The top surfaces of the first fixed roller group and the second fixed roller group are at the same height.

[0038] When in use, the first fixed roller group is positioned close to the vehicle.

[0039] The first fixed roller group includes a plurality of parallel first fixed rollers 1. Preferably, two or three first fixed rollers 1 are provided. The axis of the first fixed roller 1 is arranged along the length direction of the vehicle. The two ends of the first fixed roller 1 are rotatably connected to the first fixed frame 2 through bearing seats.

[0040] The first fixing frame 2 adopts a frame structure welded from channel steel and round steel. The top channel steel of the first fixing frame 2 is provided with bearing seats at both ends. The two ends of the first fixing roller 1 are rotatably connected to the first fixing frame 2 through the bearing seats.

[0041] The first lifting roller group includes multiple parallel first lifting rollers 3, which are parallel to the first fixed roller 1. Preferably, two first lifting rollers 3 are provided. The two ends of the first lifting rollers 3 are connected to the first lifting frame 4 through bearing seats. The first lifting frame 4 is connected to the first lifting mechanism, which can drive the first lifting frame 4 to perform lifting and lowering movements.

[0042] The first lifting frame 4 also adopts a frame structure welded from round steel. The two ends of the round steel along the length direction are fixed to the lifting plate, and the first lifting roller 3 is rotatably connected to the lifting plate through bearing seats.

[0043] like Figure 4 As shown, the first lifting mechanism includes at least two connecting rods 5, and multiple connecting rods 5 are arranged in parallel. Both ends of the connecting rod 5 are provided with sleeves 6. The sleeve 6 at the bottom end of the connecting rod 5 is rotatably connected to the connecting rod fixing rod 7. The connecting rod fixing rod 7 is fixed to the bottom end of the second fixing frame 8. The sleeve 6 at the top end of the connecting rod 5 is rotatably connected to the transverse round steel at the bottom end of the first lifting frame 4.

[0044] The second fixed frame 8 is used to place on the ground foundation and adopts a frame structure welded from multiple channel steels and round steels.

[0045] The connecting rod 5 can rotate around the connecting rod fixing rod 7, thereby changing the height of the first lifting frame 4 and thus realizing the lifting and lowering movement of the first lifting frame 4.

[0046] The first lifting mechanism further includes at least one lifting hydraulic cylinder 9, the cylinder body of the lifting hydraulic cylinder 9 is hinged to the hinge seat, and the hinge seat is fixed to the bottom end of the second fixed frame.

[0047] The piston rod of the lifting hydraulic cylinder 9 is hinged to the connecting channel steel, which is fixed between two round steels at the bottom center of the first lifting frame 4.

[0048] The extension and retraction of the piston rod of the lifting hydraulic cylinder 9 can drive the first lifting frame 4 to perform lifting and lowering movements, while multiple connecting rods 5 ensure the stability of the lifting and lowering movements of the first lifting frame.

[0049] Both sides of the first lifting roller group are provided with a first conveying component 10. In this embodiment, the first conveying component 10 adopts a chain drive mechanism installed on the top of the second fixed frame 8. The conveying direction of the chain drive mechanism is parallel to the axial direction of the first lifting roller 3 and the first fixed roller 1. It includes a driving sprocket, a driven sprocket and a conveying chain wound between the driving sprocket and the driven sprocket. The driving sprocket is connected to the first motor through the chain drive mechanism and the reducer and is driven to rotate by the first motor. The driven sprocket is rotatably connected to the top of the second fixed frame 8 through the bearing seat. The first motor and the reducer are fixed on the second fixed frame 8.

[0050] The second fixed roller group includes a plurality of parallel second fixed rollers 11. In this embodiment, two second fixed rollers 11 are provided. The second fixed rollers 11 are arranged parallel to the first fixed roller 1 and the first lifting roller 3. The two ends of the second fixed rollers 11 are rotatably connected to the top of the third fixed frame 12 through bearing seats. The third fixed frame 12 is used to be placed on the ground foundation. The third fixed frame 12 adopts a frame structure welded from round steel.

[0051] The second lifting roller assembly includes two parallel second lifting rollers 13. In this embodiment, two second lifting rollers 13 are provided. The two ends of the second lifting rollers 13 are rotatably connected to the top of the second lifting frame 14 through bearing seats. The second lifting frame 14 is connected to the second lifting mechanism, which can drive the second lifting frame 14 to perform lifting movements. Second conveying components 15 are provided on both sides of the second lifting rollers 13. The second conveying components 15 adopt a chain drive mechanism driven by a second motor. The top surface of the second conveying component 15 is flush with the top surface of the first transmission component 10. The second motor is connected to the drive sprocket of the second conveying component 15 through a reducer and the chain drive mechanism.

[0052] The second transmission component 15 is mounted on the fourth fixed frame 16, and correspondingly, the second motor and the reducer are mounted on the fourth fixed frame 16.

[0053] In this embodiment, the assembly and setting of the second lifting roller group, the second lifting frame 14, and the second lifting mechanism are the same as those of the first lifting roller group, the first lifting frame 4, and the first lifting mechanism. The only difference is the distance between the two lifting rollers, so it will not be described in detail here.

[0054] The feeding end of the turning conveyor assembly corresponds to the discharging end of the first conveyor component. The turning conveyor assembly includes a turning frame 17. In this embodiment, the turning conveyor assembly is used to turn the chicken cage conveyed on the first conveyor component 90° toward the second conveyor component. Therefore, the turning frame 17 adopts a 1 / 4 arc-shaped structure, which includes two 1 / 4 arc-shaped channel steels. The two channel steels are fixed to the top of multiple vertical round steels, and the bottom of the vertical round steels is used to place them on the ground foundation.

[0055] Multiple turning conveyor rollers 18 are provided between the top surfaces of the two channel steels, and the two ends of the turning conveyor rollers 18 are rotatably connected to the channel steels through bearing seats.

[0056] At least one of the turning conveyor rollers 18 is connected to the first rotation drive mechanism, which can drive the turning conveyor roller 18 connected to it to rotate around its own axis. Adjacent turning conveyor rollers 18 are connected through a transmission component.

[0057] In this embodiment, the transmission component adopts a transmission chain. Accordingly, a sprocket is provided at the outer end of each turning conveyor roller 18, and a transmission chain is wound between the sprockets of two adjacent turning conveyor rollers 18. One turning conveyor roller 18 located at the discharge end of the turning conveyor assembly is connected to the first rotation drive mechanism. The first rotation drive mechanism includes a third motor and a reducer. The third motor and the reducer are fixed on the turning frame 17. The output shaft of the reducer is connected to the sprocket of the turning conveyor roller at the discharge end through a chain transmission mechanism.

[0058] The third motor can drive the turning conveyor roller 18 at the discharge end to rotate, and then drive all the turning conveyor rollers 18 to rotate through the transmission chain.

[0059] The top surface of the channel steel located on the outer arc side is equipped with a protective railing, which guides the chicken cage and prevents it from falling off the turning conveyor assembly.

[0060] The reversing assembly includes a reversing frame 19, which adopts a frame structure and is welded from channel steel and round steel. The reversing assembly also includes multiple reversing conveyor rollers 20 arranged along the conveying direction. The two ends of the reversing conveyor rollers 20 are rotatably connected to the channel steel at the top of the reversing clamp through bearing seats. The reversing conveyor rollers 20 are tapered rollers, with their smaller end located close to the first conveying component.

[0061] At least one of the reversing conveyor rollers 20 is connected to the second rotation drive mechanism, and adjacent reversing conveyor rollers 20 are connected by a transmission component. The transmission component is a transmission chain. Accordingly, the inner end of the reversing conveyor roller is provided with a sprocket, and a transmission chain is wound between the sprockets of adjacent reversing conveyor rollers.

[0062] The deflection conveyor roller 20 located at the discharge end is connected to the second rotation drive mechanism. The second rotation drive mechanism includes a fourth motor and a reducer. The fourth motor and the reducer are fixed on the deflection frame 19. The output shaft of the reducer is connected to the sprocket of the deflection conveyor roller 20 at the discharge end through a chain drive mechanism.

[0063] The top surface of the channel steel at the top of the deflector frame 19 is equipped with a guardrail to prevent the chicken cage from falling off the deflector assembly.

[0064] In this embodiment, since the reversing conveyor roller 20 is a conical roller, the linear velocity of its larger end is greater than that of its smaller end, thereby enabling the chicken cage to change its angle during the conveying process.

[0065] Example 2

[0066] This embodiment provides a method for unloading caged poultry using the device described in Embodiment 1, such as... Figure 5 As shown, it is used to unload chicken cages from a vehicle. The vehicle is equipped with four rows of chicken cages, which are arranged in sequence as follows along the direction from the conveying mechanism to the cage pushing mechanism: one row of chicken cages 21, two rows of chicken cages 22, three rows of chicken cages 23 and four rows of chicken cages 24. The length direction of two rows of chicken cages is perpendicular to the length direction of the vehicle, while the length direction of the other rows of chicken cages is along the length direction of the vehicle.

[0067] The specific method is as follows:

[0068] The vehicle travels to the area between the cage pushing mechanism and the conveying mechanism.

[0069] The first lifting mechanism drives the first lifting roller 3 to rise to be flush with the top surface of the first fixed roller 1. The piston rod of the pushing hydraulic cylinder 25 of the pushing mechanism extends and pushes a row of chicken cages 21 through the first fixed roller 1 to the first lifting roller 3. The first lifting mechanism drives the first lifting roller 3 to descend until a row of chicken cages falls to the first conveying component 10. The first conveying component 10 is activated to convey a row of chicken cages 21 and send them into the turning conveying component. The turning conveying component then sends the row of chicken cages 21 out.

[0070] The first conveying component 10 stops working, and the first lifting mechanism drives the first lifting roller 3 to rise and fall until it is flush with the top surface of the first fixed roller 1.

[0071] The second lifting mechanism operates, driving the second lifting roller 13 to rise and fall to be level with the first fixed roller 1 and the second fixed roller 11.

[0072] The piston rod of the hydraulic cylinder 25 continues to extend, pushing the two rows of chicken cages 22. After passing the first fixed roller 1, the first lifting roller 3, and the second fixed roller 11, the two rows of chicken cages 22 are pushed to the second lifting roller 13, and the second lifting roller 13 is used to temporarily store the two rows of chicken cages 22.

[0073] Then, the same method as that used for the first row of chicken cages 21 was used to unload the third row of chicken cages 23 and the fourth row of chicken cages 24.

[0074] After the four rows of chicken cages 24 are unloaded, the second lifting roller 13 drives the two rows of chicken cages 22 to descend until the two rows of chicken cages 22 fall to the second conveying component 15. The second transmission component 15 is then activated, and the second transmission component 15 sends the two rows of chicken cages 22 into the reversing component. Since the reversing component uses a conical conveying roller, the reversing component realizes the rotation of the chicken cages at a set angle. In conjunction with the guiding effect of the guardrail, the chicken cages smoothly enter the turning conveying component and are sent out by the turning conveying component.

[0075] After all the chicken cages are unloaded, the first lifting roller 3, the second lifting roller 13, and the cage-pushing hydraulic cylinder 25 are reset. The vehicle leaves the area between the cage-pushing mechanism and the conveying mechanism, and the unloading device waits for the unloading task of the next vehicle.

[0076] The unloading device and method of this embodiment automate the entire unloading process, eliminating the need for manual unloading, saving manpower, improving work efficiency, and reducing the labor intensity of workers.

[0077] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
