Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to a tracked electric leaf transport vehicle for mulberry orchards that prevents slumping. Background Technology

[0002] Mulberry leaves are harvested to provide feed for silkworms. Therefore, a large number of mulberry leaves need to be collected in mulberry orchards during the silkworm rearing period. In order to improve the transportation efficiency of mulberry leaves, modern agriculture often uses electric leaf transport vehicles for mulberry leaf transportation.

[0003] During the transportation of mulberry leaves, the soil in the mulberry orchard is relatively loose, making it difficult for the leaf transport vehicles to move effectively. If it rains, the soil in the mulberry orchard becomes even looser, and even after the rain stops, it takes a long time for the soil to return to its pre-rain state, making it even more difficult for the leaf transport vehicles to move and seriously affecting the efficiency of mulberry leaf collection.

[0004] Therefore, there is a need for a tracked electric leaf transport vehicle for mulberry orchards that can adjust the ground contact area of ​​the leaf transport vehicle according to the softness of the ground to prevent the leaf transport vehicle from sinking. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a tracked electric leaf transport vehicle for mulberry orchards to prevent sinking. The distance between the two wheels B is adjusted by hydraulic cylinder B, and the distance between wheel A and the lifting platform is adjusted by hydraulic cylinder A according to the change in the distance between the two wheels B. This allows for adjustment of the contact area between the track and the ground as needed, preventing the vehicle from sinking.

[0006] This utility model is achieved through the following technical solution: a tracked electric leaf transport vehicle for preventing mulberry orchard sinking is provided, including a vehicle body with several triangular track wheels on the vehicle body; each triangular track wheel includes a base connected to the vehicle body, with a wheel A rotating on top of the base, and a drive mechanism for driving the wheel A to rotate on the vehicle body; a lifting platform is connected to the bottom of the base via a hydraulic cylinder A, and wheels B are connected to both sides of the lifting platform via hydraulic cylinders B respectively, with the two wheels B and wheel A connected by track drive; hydraulic cylinder B is activated and adjusts the distance between the two wheels B, changing the track ground contact length, thereby increasing the contact area between the vehicle body and the ground, reducing the pressure per unit area of ​​the track, and preventing the vehicle body from sinking; hydraulic cylinder A is activated and adjusts the distance between wheel A and the lifting platform according to the change in the distance between the two wheels B.

[0007] As an optimization, hydraulic cylinder A and the lifting platform are hinged together, and the base is hinged to the end of the lifting platform away from hydraulic cylinder A through a shock-absorbing mechanism; the lifting platform rotates on hydraulic cylinder A, and the shock-absorbing mechanism reduces vibration, so that the two wheels B and the track change according to the undulation of the ground, avoiding the track from being suspended in the air.

[0008] As an optimization, the base is hinged to the shock absorption mechanism via hydraulic cylinder C; as hydraulic cylinder C extends and retracts with hydraulic cylinder A, it increases the range of adjustment for the distance between the base and the lifting platform, thereby increasing the range of adjustment for the distance between the two wheel bodies B.

[0009] As an optimization, several wheels C adapted to the tracks are provided between the two wheel bodies B, and the wheels C are mounted on the lifting platform; the tracks between the two wheel bodies B are supported by the wheels C.

[0010] As an optimization, a slide rail is provided on the lifting platform, and wheel B and wheel C slide on the slide rail; wheel B and wheel C are connected to each other, and adjacent wheels C are connected by a return spring A; the return spring A and the slide rail ensure that wheel B and wheel C are arranged evenly in sequence, thereby ensuring that the track is subjected to uniform force.

[0011] As an optimization, a slider is mounted on the slide rail, and a sliding hole is opened on the slider. A guide rod is embedded in the sliding hole, and the guide rod passes through the return spring B and connects to the wheel body C. The return spring B and the guide rod ensure that the wheel body C always provides a certain pressure to the track.

[0012] The beneficial effects of this utility model are as follows: the hydraulic cylinder B starts and adjusts the distance between the two wheel bodies B, the track ground contact length changes, thereby increasing the contact area between the vehicle body and the ground, reducing the pressure per unit area of ​​the track, and preventing the vehicle body from sinking. The hydraulic cylinder A starts and adjusts the distance between the wheel body A and the lifting platform according to the change in the distance between the two wheel bodies B.

[0014] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0015] like Figures 1-3The tracked electric leaf transport vehicle for mulberry orchards, as shown in this utility model, includes a vehicle body 1 with several triangular track wheels 2 mounted on it. Each triangular track wheel 2 includes a base 201 connected to the vehicle body 1, with a wheel A202 rotating above the base 201. The vehicle body 1 is equipped with a drive mechanism 3 for driving the wheel A202 to rotate. A lifting platform 204 is connected to the bottom of the base 201 via a hydraulic cylinder A203. Wheels B206 are connected to both sides of the lifting platform 204 via hydraulic cylinders B205. The two wheels B206 and wheel A202 are connected by a track 207. The vehicle body 1, the connection method between the triangular track wheels 2 and the vehicle body 1, and the drive mechanism 3 are all existing technologies. In this embodiment, the axis of the hydraulic cylinder A203 extends vertically, and the axis of the hydraulic cylinder B205 extends horizontally. The axes of the wheel A202 and the wheel B206 are parallel to each other.

[0016] Hydraulic cylinder B205 is activated, causing the two wheels B206 to move in opposite directions on both sides of the lifting platform 204 under the action of hydraulic cylinder B205. The distance between the two wheels B206 changes, the ground contact length of track 207 changes, and the contact area between the vehicle body 1 and the ground changes, thus changing the pressure per unit area of ​​track 207. At the same time, hydraulic cylinder A203 is activated, and hydraulic cylinder A203 adjusts the distance between wheel A202 and lifting platform 204 according to the change in the distance between the two wheels B206. Until the pressure per unit area of ​​track 207 is less than the supporting force of the bottom surface, drive mechanism 3 is activated. Drive mechanism 3 drives wheel A202 to rotate, and wheel A202 drives wheel B206 to rotate through track 207. Track 207 rotates on wheel A202 and wheel B206 and drives vehicle 1 to move on the ground.

[0017] like Figures 1-3 The hydraulic cylinder A203 and the lifting platform 204 are hinged together. The base 201 is hinged to the end of the lifting platform 204 away from the hydraulic cylinder A203 through the shock absorption mechanism 208. The shock absorption mechanism 208 is existing technology and can be a vibration damper.

[0018] When the triangular track wheel 2 passes over undulating ground, the wheel body B206 on one side of the lifting platform 204 rises or falls and drives the lifting platform 204 to rotate, and the shock absorber extends and retracts to reduce shock.

[0019] like Figures 1-3 The base 201 shown is hinged to the hydraulic cylinder C209 and the shock absorption mechanism 208.

[0020] Hydraulic cylinder C209 extends and retracts along with hydraulic cylinder A203.

[0021] like Figures 1-3 Several wheels C210 adapted to the track 207 are provided between the two wheel bodies B206 shown. The wheel bodies C210 are mounted on the lifting platform 204.

[0022] Wheel C210 supports track 207.

[0023] like Figures 1-3 The lifting platform 204 shown is equipped with a slide rail 211, and wheels B206 and C210 slide on the slide rail 211; wheels B206 and C210, and adjacent wheels C210 are connected by a return spring A212; a sleeve slides on the slide rail 211, and the sleeve is fixed on the telescopic rod of the hydraulic cylinder B205. The sleeve is connected to the wheel C210 by the return spring A212.

[0024] Start hydraulic cylinder B205, and the two wheels B206 move in opposite directions on both sides of the lifting platform 204 under the action of hydraulic cylinder B205. The distance between the two wheels B206 changes, the return spring A212 extends and retracts, and the wheel C210 slides on the slide rail 211, thus changing the distance between wheel B206 and wheel C210, as well as the distance between adjacent wheels C210.

[0025] like Figures 1-3 The slide rail 211 shown has a slider 213 sliding on it. The slider 213 has a sliding hole and a guide rod 214 is provided inside the sliding hole. The guide rod 214 passes through the return spring B215 and connects to the wheel C210.

[0026] When the triangular track wheel 2 passes over undulating ground, the return spring B215 extends or retracts, the wheel body C210 rises or falls, and the track 207 always keeps in contact with the ground.

[0027] In actual production, hydraulic cylinder B205 is activated, and the two wheels B206 move in opposite directions on both sides of the lifting platform 204 under the action of hydraulic cylinder B205. The distance between the two wheels B206 changes, the ground contact length of track 207 changes, and the contact area between the vehicle body 1 and the ground changes, thus changing the pressure per unit area of ​​track 207. At the same time, return spring A212 extends and retracts, and wheel C210 slides on slide rail 211, maintaining the change in the distance between wheel B206 and wheel C210, as well as the distance between adjacent wheels C210. ​​Wheel C210 rises and falls, constantly exerting pressure on track 207. Support; simultaneously, hydraulic cylinders A203 and C209 are activated. Hydraulic cylinder A203 adjusts the distance between wheel A202 and lifting platform 204 according to the change in the distance between the two wheels B206. Hydraulic cylinder C209 extends and retracts with the extension and retraction of hydraulic cylinder A203. Until the pressure per unit area of ​​track 207 is less than the supporting force of the bottom surface, drive mechanism 3 is activated. Drive mechanism 3 drives wheel A202 to rotate. Wheel A202 drives wheel B206 to rotate through track 207. Track 207 rotates on wheel A202 and wheel B206 and drives vehicle 1 to move on the ground.

[0028] When the triangular track wheel 2 passes over undulating ground, the wheel body B206 on one side of the lifting platform 204 rises or falls and drives the lifting platform 204 to rotate. The shock absorber extends and retracts to absorb shock. At the same time, the return spring B215 extends and retracts, the wheel body C210 rises and falls and always supports the track 207, and the track 207 always keeps in contact with the ground.
