Technical Field

[0001] The utility model patent relates to tea tree pruning equipment, specifically to a tea tree branch and leaf cutting machine. Background Art

[0002] Pruning tea tree branches and leaves is one of the important tasks in tea garden management. The purpose of pruning is to adjust the crown, so that the nutrients in the plant can be fully adjusted and distributed, promote the growth of side branches, expand the crown width, and make the crown flat, cultivate a good picking surface, which is conducive to improving the yield and quality of tea.

[0003] There are three main types of mechanical tea branch and leaf cutting equipment currently in use: one is a battery-powered micro tea branch and leaf cutting machine, which has low efficiency, difficult to control the quality of picking, and a short continuous use time after a single charge; the other is a single-person tea branch and leaf cutting machine, which uses a small internal combustion engine powered by gasoline and diesel as raw materials. In order to reduce labor intensity, it is mostly operated by a single person on a backpack, and its work efficiency is higher than that of a micro-electric tea branch and leaf cutting machine; the third is a double-person tea branch and leaf cutting machine, which uses a small gasoline and diesel engine as power and is operated by two people by hand. The labor intensity is lower than that of a single tea branch and leaf cutting machine, and the efficiency is higher, but more labor is required. The above-mentioned branch and leaf cutting equipment generally requires a large amount of manpower to operate. In view of the large workload of tea branch and leaf cutting, the serious shortage of human resources, and the significant seasonal characteristics of tea growth, there is an urgent need for a branch and leaf cutting equipment that can reduce manpower consumption and is highly efficient. Summary of the invention

[0004] The utility model provides a tea tree branch and leaf cutting machine, which replaces the traditional method of cutting branches and leaves by manpower, reduces manpower consumption, and improves the efficiency of cutting branches and leaves.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted is: a tea tree branch and leaf cutting machine, a crawler walking mechanism is arranged at the bottom of the left and right sides of the vehicle body, a driving operation position is arranged above the vehicle body, and a passage A is reserved for tea trees to pass through in the area below the vehicle body and between the crawler walking mechanisms along the travel direction of the vehicle body, and a cutting mechanism is arranged at the front end of the vehicle body, and the cutting mechanism is arranged along the width direction of the vehicle.

[0006] Compared with the prior art, the technical effect of the utility model is as follows: through the arrangement of the vehicle body and the crawler walking mechanism, the personnel can control the whole machine at the driving operation position. The tea branch and leaf cutting machine can pass through the tea tree and use the cutting mechanism at its front end to cut the tea branches and leaves. The whole machine is easy to operate, replacing the traditional backpack or portable equipment cutting method, greatly reducing manpower consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following is combined with Figure 1-5 And related content, the utility model is further described in detail:

[0013] A tea tree branch and leaf cutting machine is provided with crawler-type traveling mechanisms 20 at the bottom of the left and right sides of a vehicle body 10, a driving operating position 14 is provided above the vehicle body 10, a passage A for tea trees to pass through is reserved along the travel direction of the vehicle body 10 in the area below the vehicle body 10 and between the crawler-type traveling mechanisms 20, and a cutting mechanism 40 is provided at the front end of the vehicle body 10, and the cutting mechanism 40 is arranged along the vehicle width direction.

[0014] In the above scheme, through the arrangement of the body 10 and the crawler-type walking mechanism 20, the personnel can control the whole machine at the driving operation position 14, and the tea branch and leaf cutting machine can walk on the ground, and the cutting mechanism 40 at the front end can cut the tea branches and leaves. Figure 3 , 5 As shown, since a passage A for tea trees to pass through is reserved under the body 10 along the direction of travel of the body 10, as the tea branch and leaf cutting machine moves, the pruned tea trees can pass through the passage A from under the body 10, making the whole machine easy to operate, replacing the traditional backpack or portable equipment cutting method, and reducing the manpower consumption of tea branch and leaf cutting operations. The passage A reserved between the left and right crawler walking mechanisms 20 has a suitable spacing, which not only ensures that the tea branch and leaf cutting machine can smoothly pass through the tea tree in a straddling manner, but also ensures driving safety when the body tilts when walking on a slope.

[0015] As a preferred solution, the front and rear columns 12A and 12B are respectively arranged on the lower end surfaces of the left and right sides of the vehicle body frame 11 along the front and rear ends of the vehicle body 10 in the traveling direction. The lower ends of the front and rear columns 12A and 12B are connected to a groove seat 13 with a groove opening downward and the through direction of the groove cavity is the traveling direction of the vehicle. The crawler track 23 is inserted into the groove cavity of the groove seat 13 and wound on the crawler wheel 22. The crawler wheel bracket 21 connected to the crawler wheel 22 is connected to the groove edge of the groove wall of the groove seat 13. The front and rear columns 12A and 12B are used to raise the vehicle body frame 11 as a whole, so that there is enough space under the vehicle body frame 11 for tea trees to pass through. The vehicle body 10 travels by means of the crawler track 23, which can be applied to tea fields with complex terrain.

[0016] Furthermore, there is a power wheel 24 on the track wheel bracket 21, and the track 23 is wound around the power wheel 24. The shaft end of the power output shaft 50 on the body frame 11 extends to the left and right sides of the body frame 11, and the left and right shaft ends of the power output shaft 50 and the corresponding wheel axles of the power wheel 24 form a transmission match through a belt or a chain. The power output shaft 50 drives the power wheel 24 to rotate through a belt or a chain, so that the track 23 is transmitted. In this scheme, the power output shaft 50 includes two half shafts, and the shaft ends of the two half shafts extend to the sides of the body frame 11 respectively and are connected to a driving wheel 51 to transmit with a driven wheel 241 on the wheel axle of the power wheel 24. The driving wheel 51 and the driven wheel 241 are driven by a belt or a chain to transmit torque. The driving wheel 51, the driven wheel 241 and the transmission chain or belt therebetween are located outside the left and right sides of the body frame 11, which further ensures the space in the vehicle width direction of the passage A. In addition, if there is a problem with the transmission mechanism, it is also easy to repair. Among them, under the setting of the transfer case, differential and other structures, the independent operation of the two half-axles can be realized, thereby realizing the steering operation of the vehicle body 10.

[0017] As a preferred solution, the front and rear columns 12A, 12B are connected to the middle of the upper end surface of the groove seat 13, and the upper belt of the track 23 is worn in the groove cavity of the front and rear corresponding groove seats 13, so that the track 23 and the groove seat 13 are located directly below the front and rear columns 12A, 12B as a whole, avoiding uneven stress distribution between the front and rear columns 12A, 12B and the groove seat 13 in the vehicle width direction, which may cause the structural connection position to be easily damaged.

[0018] Combination Figure 1 , 2As shown in , 3, considering that the cutting height requirements of tea tree branches and leaves are often different, in order to facilitate the adjustment of the cutting height of the cutting mechanism 40, the front end of the body 10 is connected with a vertically arranged fixed frame 30, a movable frame 31 is arranged on the fixed frame 30, and a driving unit 32 is arranged between the two to drive the movable frame 31 to move up and down, and the cutting mechanism 40 is connected to the lower end of the movable frame 31. The driving unit 32 can be composed of an oil cylinder. When the driving unit 32 drives the movable frame 31 to move up and down, the cutting mechanism 40 at its lower end can move up and down synchronously with the movable frame 31, thereby changing the height position of the cutting mechanism 40, so that its cutting height can be adjusted.

[0019] As a preferred solution, the cutting mechanism 40 includes a front baffle plate 41 with a vertical plate surface and arranged along the vehicle width direction. A cutting tool 43 extending along the vehicle width direction is arranged immediately in front of the bottom of the front baffle plate 41. The front baffle plate 41 is provided with a conveying tooth 42. The conveying tooth 42 protrudes from the plate surface of the front baffle plate 41 to the front of the plate surface. The conveying tooth 42 moves from one side of the front baffle plate 41 to the other side along the vehicle width direction. When the vehicle body 10 is moving, the cutting tool 43 can cut the branches and leaves of the tea tree. The cut branches and leaves are accumulated on the front side of the front baffle plate 41. The conveying tooth 42 pushes the cut branches and leaves, and the branches and leaves can be transported to one side of the front baffle plate 41 for centralized collection.
