Description

Technical Field

[0001] The invention belongs to the technical field of transportation, and in particular relates to a transportation device for pig breeding. Background Art

[0002] Pig transportation is an indispensable part of the pig industry chain. With the expansion of pig farming scale and the improvement of modernization, the demand for pig transportation is also increasing.

[0003] In the process of transporting live pigs, a lifting mechanism is usually used to move the live pigs in the up and down directions. For example, the patent publication number is CN113955677B, and the patent name is a transport device for pig farming. The lifting mechanism for hoisting live pigs is disclosed. The lifting mechanism includes two groups of threaded rods longitudinally symmetrically arranged in the lifting frame. The upper end of the lifting frame is fixedly installed with a motor that drives the threaded rods to rotate. The lifting frame has a built-in placement frame, and the upper end of the placement frame is fixedly connected with a movable plate. The movable plate is threadedly sleeved on the outside of the two groups of threaded rods. That is, rigid connections are usually used between the lifting mechanisms in the prior art. In the process of transportation, the dynamic behavior of live pigs in the pig cage is inevitable. On the one hand, it is easy to cause the center of gravity of the pig cage containing live pigs to shift, so that some connection points of the lifting mechanism will bear excessive loads, accelerate fatigue damage of the lifting mechanism, and shorten the service life of the equipment; on the other hand, the movement and struggle of the live pigs in the pig cage cause dynamic changes in the load, and even cause the pig cage to tilt, causing the live pigs to be frightened, further exacerbating the instability of the dynamic load. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a transfer device for pig farming, so as to solve the technical problems in the prior art that the rigid lifting mechanism used in the process of transporting pigs is prone to fatigue damage of the lifting mechanism and the pigs are easily frightened during the transportation process.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the transfer device for pig breeding of the present invention is: A transfer device for pig breeding, comprising: Connecting channel, used for docking with the pig loading platform; The transfer frame has one side connected to the end of the connecting channel away from the pig loading platform, and the other side is used to be arranged opposite to the pig transfer vehicle; The transfer rack includes an upper rack, a middle rack, and a lower rack; It also includes a pig cage for containing live pigs, and a hanging hook is fixedly arranged on the pig cage; The connecting channel is connected to the middle frame; The lower frame is provided with a transmission structure to transport the empty pig cages from the lower frame to the middle frame, so that the live pigs can enter the empty pig cages at the middle frame. The upper frame and the middle frame are arranged corresponding to the carriage of the pig transport vehicle, and a vertical transportation passage connecting the upper frame and the middle frame is arranged between the upper frame and the middle frame; The vertical transport channel is provided with a lifting structure to transport the pig cages containing live pigs to the corresponding height of the carriage; A lifting mechanism is arranged on the upper frame, and is used to lift the pig cage containing the live pigs onto the lifting structure; The lifting mechanism is adjustable in position along the left and right directions, and comprises a lifting assembly, a fixed cylinder arranged below the lifting assembly, and a transition assembly detachably connected to the fixed cylinder; The transition component and the hook of the pig cage can be automatically disconnected and hung; The transition component includes a first working state of rigid connection relative to the fixed cylinder and a second working state of flexible connection relative to the fixed cylinder, so as to realize the rigid-flexible conversion of the pig cage relative to the lifting mechanism.

[0006] Beneficial effect: A lifting mechanism is arranged on the transfer frame of the transfer device in the present invention, and the lifting mechanism includes a lifting component, a fixed cylinder arranged below the lifting component, and a transition component detachably connected to the fixed cylinder. The transition component and the hook of the pig cage can be automatically detached, so as to facilitate the connection and disassembly of the lifting mechanism and the pig cage; the transition component includes a first working state rigidly connected to the fixed cylinder and a second working state flexibly connected to the fixed cylinder, so that the rigid-flexible conversion of the pig cage relative to the lifting mechanism is realized by adjusting the first working state and the second working state of the transition component, and the pig cage can be connected to the lifting mechanism in a flexible manner. When the pig cage is initially lifted, a rigid connection is ensured between the pig cage and the lifting mechanism. After the lifting mechanism lifts the pig cage, a flexible connection is maintained between the pig cage and the lifting mechanism, so as to adjust the center of gravity of the pig cage containing the live pigs, and avoid excessive loads on certain connection points of the lifting mechanism due to the rigid connection, thereby accelerating fatigue damage of the lifting mechanism. It can also avoid the movement and struggle of the live pigs in the pig cage, as the live pigs are easily frightened due to the rigid connection between the live pigs and the pig cage. That is, the transfer device of the present invention can not only make the lifting mechanism have a longer service life, but also reduce the risk of the live pigs being frightened during the transfer process.

[0038] The plug-in portion 43 includes a guide column 44 at the upper end and a connecting column 45 fixed at the lower part of the guide column 44. The connecting column 45 is coaxially arranged with the guide column 44. The diameter of the connecting column 45 is smaller than that of the guide column 44. The guide column 44 is adapted to slide with the fixed cylinder 41. A first support plate 46 is fixed to the lower end of the fixed cylinder 41. The clamping structure is a first electric telescopic rod 47 arranged on the first support plate 46. The first electric telescopic rod 47 can be extended and retracted in the horizontal direction. A hoop is fixed to the end of the first electric telescopic rod 47. The fixed cylinder is provided with an avoidance The first through hole 48 of the clamp on the first electric telescopic rod 47, when the first electric telescopic rod 47 is extended horizontally, the clamp passes through the first through hole 48 and clamps the connecting column 45 of the plug-in part 43 to realize the rigid connection between the fixed cylinder 41 and the transition assembly; when the first electric telescopic rod 47 is retracted horizontally, the clamp releases the connecting column 45 of the plug-in part 43, the second plate body 37 moves upward relative to the first plate body 36, the plug-in part 43 is moved out of the fixed cylinder body 41 and connected to the lifting assembly through the flexible rope 55 to realize the flexible connection between the fixed cylinder body 41 and the transition assembly.

[0039] In this embodiment, the hook on the pig cage 8 is arranged corresponding to the transition component, and the hook includes an upper cylindrical section 52, a middle cylindrical section 53, and a lower cylindrical section 54 which are coaxially arranged above and below. The diameter of the upper cylindrical section 52 is equal to the diameter of the lower cylindrical section 54, and the diameter of the middle cylindrical section 53 is smaller than the diameter of the upper cylindrical section 52; the lower cylindrical section 54 is fixedly connected to the pig cage 8; the transition component includes a connecting tube 49 fixed at the lower part of the plug-in portion 43 and a clamping structure capable of clamping the hook, the upper cylindrical section 52 is guided and matched with the connecting tube 49, and a second support plate 50 is fixed to the lower end of the connecting tube 49, and the clamping structure is a second electric telescopic rod 51 arranged on the second support plate 50, and a clamping hoop is fixed to the end of the second electric telescopic rod 51, and a second through hole is opened on the connecting tube 49 to avoid the clamping hoop on the second electric telescopic rod 51. When the second electric telescopic rod 51 is extended, the clamping hoop can clamp the middle cylindrical section 53 of the hook to realize the fixed connection between the lifting mechanism 7 and the pig cage 8.

[0040] In this embodiment, a cover body that can be opened and closed automatically is arranged on the front side of the pig cage 8. The arrangement of the cover body relative to the pig cage 8 and the closing of the cover body relative to the pig cage 8 belong to the prior art and will not be described in detail here.

[0041] In this embodiment, after the live pigs enter the empty pig cage 8, the telescopic structure 38 of the lifting assembly of the lifting mechanism 7 extends, and the second plate body 37 moves downward relative to the first plate body 36. During the movement, the transition assembly of the lifting mechanism 7 moves downward relative to the pig cage 8, and the connecting tube 49 of the transition assembly moves downward relative to the hook of the pig cage 8, and the upper cylindrical section 52 and the middle cylindrical section 53 of the hook are inserted into the connecting tube 49. A first pressure sensor is provided on the top of the connecting tube 49, and the first pressure sensor is connected to the controller control. When the hook is pressed on the top of the connecting tube 49, the first pressure sensor gives a signal to the controller, and the controller controls the telescopic structure 38 to stop extending, and then the controller controls the second electric telescopic rod 51 to extend, and the second electric telescopic rod 51 passes through the second through hole and causes the clamp to clamp the middle cylindrical section 53 of the hook, thereby realizing the automatic connection between the lifting mechanism 7 and the hook of the pig cage 8.

[0042] When the pig cage 8 is connected to the lifting mechanism 7, the controller controls the telescopic structure 38 of the lifting assembly to retract, so that the lifting mechanism 7 can lift the pig cage 8. After lifting to a certain height, the telescopic structure 38 extends again, and the first electric telescopic rod 47 on the first support plate 46 retracts. At the same time, the hoisting mechanism 39 unwinds the flexible rope 55, so that the plug-in part 43 on the transition assembly is disengaged from the fixed cylinder 41.
