[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0030] Please see Figure 1-4 As shown, this utility model is a hydraulic lifting tailgate structure for a fertilizer loading and unloading vehicle, comprising:
[0031] Tailgate 150, the bottom of which is connected to the bottom of the carriage with a hydraulic mechanism;
[0032] The hydraulic mechanism includes a hydraulic rod 110, a corner column 120, a rotating tube 130, and a fixed rod 140;
[0033] One end of the hydraulic rod 110 is rotatably connected to the bottom of the carriage, and the other end of the hydraulic rod 110 is rotatably connected to one end of the corner post 120. The rotating tube 130 is rotatably connected to the outside of the bottom of the carriage, and the other end of the corner post 120 is fixedly connected to the side wall of the rotating tube 130. There are two fixing rods 140. One end of the two fixing rods 140 is fixedly connected to both ends of the side wall of the rotating tube 130, and the other end of the two fixing rods 140 is fixedly connected to the bottom end of the tail plate 150. When the hydraulic rod 110 is extended or shortened, it causes one end of the corner post 120 to move. The other end of the corner post 120 causes the rotating tube 130 to rotate. The rotating tube 130 causes the insertion hole 240 to move. The fixing rod 140 causes one end of the tail plate 150 to move, causing the other end of the tail plate 150 to flip, thus realizing the reciprocating flipping of the tail plate 150.
[0034] Two first lower mounting plates 111 and two second lower mounting plates 114 are fixedly connected to the bottom of the carriage. A first connecting column 112 is fixedly connected between the two first lower mounting plates 111, and a second connecting column 115 is fixedly connected between the two second lower mounting plates 114. A rotating tube 130 is rotatably connected to the second connecting column 115. The corner column 120 rotates under the drive of the hydraulic rod 110, causing the other end of the corner column 120 to drive the rotating tube 130 to rotate on the second connecting column 115.
[0035] The tail plate 150 is fixedly connected to the two sides of the front, and the side posts 161 are fixedly connected to the end and middle of the side wall of the railing 160. The bottom of the side post 161 is provided with a gate 170. The top two ends of the gate 170 are rotatably connected to the top of the side wall of the railing 160. The railing 160 prevents fertilizer from sliding off the sides of the tail plate 150. The side posts 161 connect the two railings 160 into a whole to increase stability. The gate 170 and the railing 160 enclose a fertilizer placement area.
[0036] The hydraulic rod 110 has a first connector 113 and a second connector 116 fixedly connected to both ends. The corner post 120 has a connecting groove 121 at one end, and a third connecting post 122 is fixedly connected in the middle of the connecting groove 121. The first connector 113 is rotatably connected to the first connecting post 112, and the second connector 116 is rotatably connected to the third connecting post 122. The extension and retraction of the hydraulic rod 110 causes the first connector 113 and the second connector 116 at both ends of the hydraulic rod 110 to rotate on the first connecting post 112 and the third connecting post 122, respectively.
[0037] Working principle: When loading and unloading fertilizer, the fertilizer is placed in an area enclosed by the gate 170 and the railing 160. The hydraulic rod 110 is activated to reciprocate and extend. The extension and retraction of the hydraulic rod 110 causes the first connector 113 and the second connector 116 at both ends of the hydraulic rod 110 to rotate on the first connecting column 112 and the third connecting column 122, respectively. At the same time, the end of the hydraulic rod 110 drives one end of the corner column 120 to move. The other end of the corner column 120 rotates the tube 130 on the second connecting column 115. The rotating tube 130 drives one end of the fixed rod 140 to move, causing one end of the tail plate 150 at the other end of the fixed rod 140 to move and flip the other end of the tail plate 150. This allows the tail plate 150 to flip back and forth, so that the fertilizer slides along the tail plate 150 to the carriage or the trolley on the ground, completing the loading and unloading. There is no need for manual pushing of the trolley onto the tail plate 150, avoiding the tail plate 150 from breaking due to overload and causing personal injury.
[0038] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:
[0039] The top of both ends of the gate 170 is fixedly connected with protruding posts 171, which are rotatably connected to the top of the side wall of the railing 160. A locking mechanism is provided in the middle of the front of the gate 170. When loading, the gate 170 at the end of the railing 160 is fixed by the locking mechanism. When unloading, the gate 170 in the middle of the railing 160 is fixed by the locking mechanism.
[0040] The locking mechanism includes a sliding plate 210, a push plate 220, a first spring 230, and a socket 240;
[0041] Two sliding plates 210 are slidably connected to the center of the front of the gate 170. The push plate 220 is fixedly connected to the center of the sliding plate 210 with the two end posts. There are two first springs 230, with the two ends of the first springs 230 fixedly connected to the top end of the tail plate 150 and the bottom surface of the sliding plate 210 respectively. There are multiple insertion holes 240, which are respectively opened at one end and the middle of the bottom surface of the tail plate 150. Pushing the push plate 220 causes the end posts of the push plate 220 to insert into the corresponding insertion holes 240, while simultaneously driving the sliding plate 210 to slide. The sliding of the sliding plate 210 compresses the first springs 230. After the end posts of the push plate 220 are inserted into the insertion holes 240, the gate 170 is fixed and cannot be flipped.
[0042] It also includes a limiting component 250, which includes a square tube 251, a stop post 252, a pull rod 253, a second spring 254, and a pull plate 255;
[0043] The square tube 251 is fixedly connected to the center of the front of the tail plate 150. The stop post 252 is slidably connected inside the square tube 251. One end of the pull rod 253 is fixedly connected to the side wall of the stop post 252. The two ends of the second spring 254 are fixedly connected to the side wall of the stop post 252 and the side wall of the square tube 251, respectively. The pull plate 255 is fixedly connected to the other end of the pull rod 253. Before pushing the push plate 220, the pull plate 255 is pulled to drive the pull rod 253 to pull the stop post 252 into the square tube 251 and compress the second spring 254. After pushing the push plate 220 to insert the pins at both ends of the push plate 220 into the insertion hole 240, the pull plate 255 is released to allow the second spring 254 to rebound and drive the stop post 252 to slide out of the square tube 251 to block the top surface of the push plate 220, so that the pins at both ends of the push plate 220 remain inserted into the insertion hole 240.
[0044] Working principle: During loading, pulling the middle pull plate 255 of the stop gate 170 at the end of the railing 160 drives the pull rod 253 to pull the stop post 252 into the square tube 251, compressing the second spring 254. Then, pushing the middle push plate 220 of the stop gate 170 at the end of the railing 160 causes the pins at both ends of the push plate 220 to insert into the corresponding insertion holes 240, simultaneously causing the sliding plate 210 to slide. The sliding plate 210 compresses the first spring 230, and the pins at both ends of the push plate 220 insert into the insertion holes 240. Releasing the pull plate 255 causes the second spring 254 to... 4. The rebound causes the stop post 252 to slide out of the square tube 251 and block the top surface of the push plate 220, so that the inserts at both ends of the push plate 220 are kept inserted into the insertion hole 240, and the stop gate 170 at the end of the railing 160 is fixed. After the tail plate 150 flips onto the car body, the waste slides down and flips the middle stop gate 170. Similarly, during unloading, the locking mechanism fixes the middle stop gate 170 of the railing 160, so that when the waste slides down the tail plate 150 into the trolley on the ground, the end stop gate 170 flips down, so that the fertilizer can be blocked during loading and unloading to prevent it from sliding down in the opposite direction.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
