[0002] With the gradual promotion of agricultural mechanization technology, farmers are no longer limited to the traditional shoulder-carrying and livestock-dependent farming, but have gradually begun to apply agricultural machinery and equipment to agricultural production. In the actual agricultural production process, as the horsepower of agricultural machinery tractors increases, the corresponding machines (such as rotary tillers, drive tillers, etc.) become wider and longer. Nowadays, the practice is to design agricultural tools larger than 3-4 meters into a folding mode, which is expensive and complex in structure. When the integrated equipment starts from the base, the power machinery moves independently, and the equipment is hoisted to another vehicle for transportation. When it arrives at the land, it is hoisted and unloaded, and then combined with the power machinery to carry out the operation.

DETAILED DESCRIPTION
[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] like Figure 1 to Figure 8 As shown, this embodiment proposes an agricultural machinery and implement transport lifting platform vehicle, including a plate body 1, one end of the top of the plate body 1 is fixedly connected to a fixing frame 2, one end of the fixing frame 2 is provided with a connecting mechanism 3 for connecting to a tractor body 4, the other end of the plate body 1 is provided with a walking mechanism 5, the walking mechanism 5 includes two parallel mounting seats 51, the two mounting seats 51 are fixedly connected to the bottom of the plate body 1, the inner sides of the two mounting seats 51 are rotatably connected to a rotating rod 52, the bottom ends of the two rotating rods 52 are rotatably connected to walking wheels 53, the top of the plate body 1 is hinged with two parallel first hydraulic rods 54, the output ends of the two first hydraulic rods 54 are hinged to the middle parts of the corresponding rotating rods 52, and the bottom of the plate body 1 is provided with a buffer member 55 for shock absorbing the plate body 1 by cooperating with the rotation of the rotating rod 52 and contacting the bottom surface.
[0020] When loading the implement, the two first hydraulic rods 54 are controlled to make the two rotating rods 52 rotate downward, so that the two walking wheels 53 are in contact with the ground and support the board body 1. Then the implement can be placed on the board body 1, and then the tractor body 4 acts on the connecting mechanism 3 and drags the board body 1, so that the walking wheels 53 of the board body 1 move on the road. When driving to the field, the board body 1 is separated from the tractor body 4 by operating the connecting mechanism 3. Then the board body 1 can be manually pulled to transfer the implement to the corresponding working position, and finally the implement is installed on the tractor body 4 for field operation. The entire tool transportation process can be completed by the driver alone, and there is no need to transport the tool by a separate vehicle, which greatly reduces the transportation cost of the tool.
[0021] Furthermore, the buffer member 55 includes two elastic rods 552 arranged in parallel, the top ends of the two elastic rods 552 are rotatably connected to the bottom wall of the plate body 1, the bottom ends of the two elastic rods 552 are rotatably connected to the guide wheel 554, the rotating rod 52 is coaxially fixedly connected to the first gear 551, the elastic rod 552 is coaxially fixedly connected to the second gear 553, the second gear 553 is meshed with the first gear 551, the length of the elastic rod 552 is greater than the length of the rotating rod 52, and the number of teeth of the first gear 551 and the second gear 553 are the same.
[0022] When loading the tool, the two first hydraulic rods 54 are controlled to make the two rotating rods 52 rotate downward, so that the two walking wheels 53 move downward and contact the ground. In this process, the first gear 551 will rotate synchronously with the rotating rod 52, so that the second gear 553 drives the two elastic rods 552 to move downward. Since the length of the elastic rod 552 is greater than the rotating rod 52, the guide wheel 554 first contacts the ground. At the same time, the guide wheel 554 is subjected to the reaction force of the ground, so that the guide wheel 554 applies pressure to the elastic rod 552, so that the elastic rod 552 can be compressed to generate reverse elastic force, thereby buffering the plate body 1, and further avoiding the problem of the plate body 1 vibrating violently and causing the tool to fall when the guide wheel 554 contacts the ground.
[0023] Furthermore, the elastic rod 552 includes a rod sleeve 5521, the top of the rod sleeve 5521 is rotatably connected to the bottom wall of the plate body 1, the bottom end of the rod sleeve 5521 is slidably connected to the insertion rod 5522, the bottom end of the insertion rod 5522 is rotatably connected to the guide wheel 554, the inner side of the rod sleeve 5521 is slidably connected to the slider 5523, the slider 5523 is fixedly connected to the top of the insertion rod 5522, the inner side of the rod sleeve 5521 is sleeved with a first spring 5524, the top of the first spring 5524 is in contact with the top wall inside the rod sleeve 5521, and the bottom end of the first spring 5524 is in contact with the slider 5523. When the guide wheel 554 contacts the ground, the insertion rod 5522 will slide due to the squeezing of the guide wheel 554, causing the slider 5523 to slide and squeeze the first spring 5524. After being squeezed, the first spring 5524 generates a reverse elastic force for buffering, thereby buffering the guide wheel 554 to reduce the impact force on the guide wheel 554 when landing.
[0024] Furthermore, the connecting mechanism 3 includes a connecting rod 31, one end of the connecting rod 31 is fixedly connected to the fixing frame 2, the other end of the connecting rod 31 is slidably matched with a socket 33, the top of the socket 33 is fixedly connected to a movable arm 32, the end of the movable arm 32 away from the socket 33 is hinged to the tractor body 4, the middle part of the bottom surface of the movable arm 32 is hinged to a second hydraulic rod 34, the end of the second hydraulic rod 34 away from the movable arm 32 is hinged to the tractor body 4, a limiting hole 35 is provided in the middle of the connecting rod 31, and a hole 35 is provided on the outer side of the socket 33 for limiting the connection rod 31 from being separated from the socket 33. The limiting member 36 comprises a fixing plate 361, which is fixedly connected to the outer side of the socket 33; one end of the fixing plate 361 is slidably connected to a limiting rod 362 which passes through the fixing plate 361; the bottom end of the limiting rod 362 is slidably matched with the limiting hole 35; the top end of the limiting rod 362 is fixedly connected to a pulling block 363; the middle part of the limiting rod 362 is fixedly connected to a stopper 364; a second spring 365 is sleeved on the limiting rod 362; the top end of the second spring 365 abuts against the fixing plate 361; the bottom end of the second spring 365 abuts against the stopper 364.
[0025] During installation, the connecting rod 31 is inserted into the socket 33, and then the limiting rod 362 is slidably matched with the limiting hole 35, which can limit the separation of the limiting rod 362 from the socket 33, so that the fixing frame 2 and the tractor body 4 remain relatively fixed, so that the plate body 1 can move synchronously with the tractor body 4; during disassembly, the limiting rod 362 is moved upward by pulling the pull block 363 upward, so that the limiting rod 362 is separated from the limiting hole 35, so that the connecting rod 31 can be directly pulled out of the socket 33, and the plate body 1 can be separated from the tractor body 4. The entire structure can realize the rapid disassembly and assembly of the plate body 1, and the operation is very convenient.
[0026] Furthermore, an extension mechanism 6 is provided at the top of the plate body 1, and the extension mechanism 6 includes two parallel fixed seats 61, the two fixed seats 61 are fixedly connected to the bottom of the plate body 1, an internal threaded sleeve 62 is rotatably connected between the two fixed seats 61, a rotating cap 63 is fixedly connected to the middle of the internal threaded sleeve 62, both ends of the internal threaded sleeve 62 are threadedly connected with screws 64, the thread directions of the two screws 64 are opposite, and one end of the two screws 64 away from the internal threaded sleeve 62 is fixedly connected with a connecting plate 65, and the tops of the two connecting plates 65 are fixedly connected with extension plates 66, and the two extension plates 66 are respectively slidably connected to the two ends of the top of the plate body 1, and mounting grooves 11 are opened at both ends of the top wall of the plate body 1, and the two extension plates 66 are slidably matched with the corresponding mounting grooves 11.
[0027] When the width of the tool is wider, the internal threaded sleeve 62 is rotated by rotating the rotating cap 63, so that the internal threaded sleeve 62 and the two screws 64 rotate relative to each other. Since the spiral directions of the two screws 64 are opposite, the two screws 64 move toward or away from each other, so that the two extension plates 66 can extend outward along the two ends of the plate body 1, thereby extending the width of the plate body 1, and then meeting the loading needs of tools with a larger width, greatly improving the versatility of the overall trailer.
[0028] Working principle: When loading the implement, the movable arm 32 is moved downward by controlling the second hydraulic rod 34, so that the plate body 1 is moved downward and maintained in a horizontal state, and the two first hydraulic rods 54 are controlled to make the two rotating rods 52 rotate downward, so that the two walking wheels 53 are in contact with the ground and support the plate body 1, and then the implement can be placed on the plate body 1, and then the tractor body 4 acts on the fixed frame 2 and drags the plate body 1, so that the walking wheels 53 of the plate body 1 walk on the road, and when driving to the field, the limit rod 362 is moved upward by pulling the pull block 363 upward, so that the limit rod 362 is disengaged from the limit hole 35, so that the connecting rod 31 can be directly pulled out of the socket 33, and the plate body 1 can be disengaged from the tractor body 4, and then the implement can be transported to the corresponding working position by manually pulling the plate body 1, and finally the implement is installed on the tractor body 4 for field operation, and the entire tool transportation process only needs the driver to complete it, and there is no need to transport the implement by a separate vehicle, which greatly reduces the transportation cost of the implement.
[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
