Technical Field

[0001] The utility model relates to the technical field of crawler chassis, in particular to a crawler chassis for an intelligent tea harvester for hilly and mountainous areas. Background Art

[0002] Tea, commonly known as tea, generally consists of the leaves and buds of the Camellia sinensis plant. Tea contains ingredients such as catechins, cholestenone, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. Tea leaves are usually harvested by hand or by machine.

[0003] Tea pluckers are harvesting machines that collect young tea leaves from the tops of tea trees. They are classified into two types, selective and non-selective, depending on the method used. When in use, tea pluckers typically use tracks as moving parts.

[0004] When the crawler chassis of the existing tea harvester is in use, it is often difficult for the crawler to move smoothly due to the large amount of soil, sand and mud on the ground during movement, and the soil, sand and mud are easily attached to the crawler, making it inconvenient to clean it; therefore, it does not meet the existing needs. In this regard, we propose a crawler chassis for an intelligent tea harvester for hilly and mountainous areas. Utility Model Content

[0005] The purpose of the present utility model is to provide a crawler chassis for an intelligent tea harvester for hilly and mountainous areas, so as to solve the problems that the crawler chassis of the tea harvester proposed in the above-mentioned background technology often has difficulty in moving the crawler smoothly due to the large amount of soil, sand and mud on the ground during movement, and the soil, sand and mud are easily attached to the crawler, making it inconvenient to clean the crawler.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a crawler chassis for an intelligent tea harvester for hilly and mountainous areas, comprising a top plate, four support plates movably installed on both sides of the bottom end of the top plate, a lifting platform provided under the support plate, two electric push rods fixedly installed on both sides of the top end of the lifting platform, the output ends of the electric push rods fixedly connected to the bottom end of the support plate, a fixed bracket fixedly installed at the bottom end of the lifting platform, connecting plates fixedly installed at both ends of the fixed bracket, and conical baffles rotatably installed on the inner side of the connecting plate.

[0008] Preferably, the outer surface of the lifting platform is provided with an arc-shaped groove, the arc-shaped plates are slidably inserted into the interior of the arc-shaped groove, and a bending spring is movably installed between the arc-shaped plates and the interior of the arc-shaped groove.

[0009] Preferably, a torsion spring is movably installed at the connection position of the conical baffle and the connecting plate, two mounting holes are provided on the surface of the support plate, and the top plate and the support plate are threadedly connected via bolts and the mounting holes.

[0010] Preferably, a crawler track is movably mounted on the bottom end of the fixed bracket, two wheels are rotatably mounted inside the crawler track, side baffles are fixedly mounted on both sides of the fixed bracket, and the crawler track is movably inserted into the position between the two side baffles.

[0011] Preferably, a fixing block is fixedly installed between the two side baffles, and connecting rods are fixedly installed on both sides of the fixing block, and the connecting rods are rotatably connected to the surface of the rotating wheel.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model is provided with a conical baffle. When the device is in use, the conical baffle can be rotated outward so that the bottom end of the conical baffle is close to the ground. At this time, when the device moves, the sharp part of the front end of the conical baffle can push the soil, sand and mud in front, so as to prevent the soil, sand and mud from adhering to the surface of the crawler when it passes, thereby increasing the service life of the crawler and preventing soil, sand and mud from being stuck on the crawler surface, thereby reducing the complexity of crawler cleaning;

[0014] 2. The utility model cooperates with the fixed ring and the arc plate. When the conical baffle is not needed, the conical baffle can be rotated upward to make the fixed ring close to the position of the arc plate. At this time, the arc plate is pressed into the inside of the arc groove. Then, the arc plate will be ejected by the elastic potential energy of the bending spring and stuck into the inside of the fixed ring, thereby fixing the conical baffle above the crawler track, avoiding the situation where the conical baffle interferes with the vehicle's progress on uphill terrain.

[0015] 3.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figures 1 to 5 The utility model provides an embodiment: a crawler chassis for an intelligent tea harvester in hilly and mountainous areas, comprising a top plate 1, four support plates 2 are movably installed on both sides of the bottom end of the top plate 1, a lifting platform 4 is provided under the support plates 2, two electric push rods 3 are fixedly installed on both sides of the top of the lifting platform 4, the output ends of the electric push rods 3 are fixedly connected to the bottom ends of the support plates 2, a fixed bracket 6 is fixedly installed at the bottom end of the lifting platform 4, connecting plates 7 are fixedly installed at both ends of the fixed bracket 6, and conical baffles 8 are rotatably installed on the inner sides of the connecting plates 7.

[0024] Through the cooperation of the support plate 2 and the electric push rod 3, when the device is in use, the electric push rod 3 can drive the output end to push out to adjust the height of the support plate 2, and then adjust the height of the top plate 1, so that the device can adjust the distance between the bottom end of the top plate 1 and the ground, thereby adapting to tea trees of different heights for harvesting.

[0025] The outer surface of the conical baffle 8 is fixedly mounted with a fixed ring 9 , and the outer surface of the lifting platform 4 is movably mounted with an arc-shaped plate 5 , which is movably snapped into the interior of the fixed ring 9 .

[0026] Through the setting of the conical baffle 8, when the device is in use, the conical baffle 8 can be rotated outward so that the bottom end of the conical baffle 8 is close to the ground. At this time, when the device moves, the sharp part of the front end of the conical baffle 8 can push the soil, sand and mud in front to avoid the soil, sand and mud adhering to the surface of the crawler 11 when it passes. This makes the crawler 11 move forward more smoothly, while increasing the service life of the crawler 11 and avoiding soil, sand and mud from being stuck on the surface of the crawler 11, thereby reducing the complexity of cleaning the crawler 11.

[0027] The outer surface of the lifting platform 4 is provided with an arc groove 16 , and the arc plate 5 is slidably inserted into the interior of the arc groove 16 . A bending spring 17 is movably installed between the arc plate 5 and the interior of the arc groove 16 .

[0028] Through the cooperation of the fixed ring 9 and the arc plate 5, when the conical baffle 8 is not needed, the conical baffle 8 can be rotated upward to make the fixed ring 9 close to the position of the arc plate 5. At this time, the arc plate 5 is pressed into the inside of the arc groove 16. Then the arc plate 5 will be ejected by the elastic potential energy of the bending spring 17 and stuck into the inside of the fixed ring 9, thereby fixing the conical baffle 8 above the track 11, avoiding the situation where the conical baffle 8 is interfered with and unable to move forward on uphill terrain.

[0029] Torsion springs are movably installed at the connection positions of the conical baffle 8 and the connecting plate 7. Two mounting holes 13 are provided on the surface of the support plate 2. The top plate 1 and the support plate 2 are threadedly connected through bolts and the mounting holes 13.

[0030] A crawler 11 is movably installed at the bottom end of the fixed bracket 6, and two wheels 12 are rotatably installed inside the crawler 11. Side baffles 10 are fixedly installed on both sides of the fixed bracket 6, and the crawler 11 is movably stuck in the position between the two side baffles 10. A servo motor is fixedly installed on the outer side of the side baffle 10 on one side, and the output end of the servo motor is connected to the wheel 12 on one side through a chain.

[0031] A fixing block 14 is fixedly installed between the two side baffles 10 , and connecting rods 15 are fixedly installed on both sides of the fixing block 14 . The connecting rods 15 are rotatably connected to the surface of the rotating wheel 12 .

[0032] When the crawler chassis of the intelligent tea harvester for hilly and mountainous areas is in use, when there is a lot of soil, sand and mud on the ground that affects the movement of the crawler 11, the conical baffle 8 can be rotated outward so that the bottom end of the conical baffle 8 is close to the ground. At this time, when the device moves, the soil, sand and mud in front can be pushed by the sharp part of the front end of the conical baffle 8, so as to prevent the soil, sand and mud from adhering to the surface of the crawler 11 when it passes. At the same time, the crawler 11 is made to move forward more stably, and the service life of the crawler 11 is increased, and soil, sand and mud are prevented from being stuck on the surface of the crawler 11, thereby reducing the complexity of cleaning the crawler 11.

[0033] When going uphill, the conical baffle 8 is not needed. The conical baffle 8 can be rotated upward to make the fixed ring 9 close to the position of the curved plate 5. At this time, the curved plate 5 is pressed into the inside of the arc groove 16. Then, the curved plate 5 is ejected by the elastic potential energy of the bending spring 17 and is stuck in the inside of the fixed ring 9, thereby fixing the conical baffle 8 above the crawler 11, avoiding the situation where the conical baffle 8 is interfered with and cannot move forward on uphill terrain;

[0034] The output end is driven out by the electric push rod 3 to adjust the height of the support plate 2, and then the height of the top plate 1 is adjusted, so that the device can adjust the distance between the bottom end of the top plate 1 and the ground, thereby adapting to tea trees of different heights for harvesting.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
