Description

Technical Field

[0001] The utility model relates to the technical field of tea picking, in particular to a crawler type tea picking machine. Background Art

[0002] The traditional way of picking tea is to pick tea manually. Long-term labor leads to backache and finger pain. Then a semi-automatic tea picking tool appeared. The tea picking tool can automatically cut tea leaves, but it does not have the function of storing tea leaves. When using it, the tea picker uses both hands. The right hand holds the tea picking tool and sweeps the top surface of the tea table horizontally, and the left hand holds the basket to receive the swept tea leaves. In order to solve the problem of tea storage, a tea picking device has appeared. The front end of the tea picking device is provided with a cutting component and an air supply system. The cutting component is used to automatically cut tea leaves, and the air supply system is used to blow the cut tea leaves to the rear end of the device. A cloth bag is provided at the rear end of the device for storing tea leaves. However, this tea picking device requires the cooperation of multiple people when used. Two people lift and control the front end of the tea picking device, and one person lifts the cloth bag. It is inconvenient to use, so this scheme designs an automatic tea picking machine.

[0023] like Figure 1 , Figure 3 As shown, this embodiment provides a crawler type tea picking machine, including a crawler chassis 1, a lifting frame 2, a cutting assembly 3, an air supply system 4, a conveying pipeline 5, and a storage bin 6.

[0024] The crawler chassis 1 is a prior art, has sufficient strength and rigidity, and has good traveling and turning capabilities, and is widely used in field operations such as engineering machinery and agricultural machinery. Figure 1 , Figure 2 As shown, the lifting frame 2 is arranged on the top of the crawler chassis 1, and a platform 21 is arranged on the top of the lifting frame 2. The lifting frame 2 is driven by a hydraulic cylinder to adjust the height of the platform 21. The lifting frame 2 is a prior art, and its structure and principle are not described in detail here.

[0025] like Figure 1 , Figure 3 As shown, the conveying pipe 5 is tilted above the lifting frame 2 through multiple brackets, a conveyor belt is provided in the conveying pipe 5, the cutting component 3 is arranged in the shell 31, the shell 31 is arranged at the lower end of the conveying pipe 5, the shell 31 is connected to the conveying pipe 5, the cutting component 3 is used to cut tea leaves, in order to improve the application scope of the cutting component 3, it is used to cut tea tables of different widths, and a cutting component 3 with adjustable length can be selected, or a cutting component 3 with a fixed length but a length much larger than the width of the tea table can be selected. The cutting component 3 is a prior art, and its structure and principle are not elaborated in detail here. The air supply system 4 is arranged on the top of the shell 31, and the air supply system 4 is used to blow the cut tea leaves into the conveying pipe 5, and the conveyor belt in the conveying pipe 5 is used to transport the tea leaves obliquely upward.

[0026] like Figure 1 As shown, the storage bin 6 is arranged on the top of the platform 21, and the storage bin 6 is used to receive the tea leaves transported by the conveying pipe 5. In order to facilitate the complete collection of the tea leaves into the storage bin 6, the feed port of the storage bin 6 and the conveying pipe 5 are connected through a first cloth bag in this embodiment, and one end of the first cloth bag is put on the conveying pipe 5 and tied with wire, and the other end of the first cloth bag is put on the feed port of the storage bin 6 and also tied with wire.

[0027] When picking tea leaves, the crawler chassis 1 moves along one of the tea tables, and the tea table is located below the crawler chassis 1. During the movement, the ground of the tea garden is rugged and uneven. The height of the cutting assembly 3 and the conveying pipe 5 is adjusted by the lifting frame 2, and then the cutting assembly 3 is used to cut the tea leaves. The air supply system 4 blows the cut tea leaves into the conveying pipe 5. The conveyor belt in the conveying pipe 5 tilts upward to transport the tea leaves, and finally the tea leaves are collected in the storage bin 6. This embodiment realizes automatic picking and collection of tea leaves, which greatly saves manpower.

[0028] like Figure 1 As shown, in order to make the platform 21 have a steering function, the present embodiment adopts the following measures: a support plate 22 is provided on the top of the lifting frame 2, a turntable 23 is provided on the top of the support plate 22, a motor is provided in the turntable 23, an output shaft on the top of the motor is connected to the platform 21, and the motor is used to rotate the platform 21.

[0029] The above scheme can be used to pick young tea leaves on the top of the tea table, and can also be used to pick old tea leaves on the top of the tea table. When picking old tea leaves, the integrity of the tea leaves does not need to be considered. Even the old tea leaves will be crushed after harvesting. The problem is that the picked old tea leaves cannot be crushed at the picking site, but are further crushed after being transported to a processing plant or warehouse. Therefore, in order to solve the problem of picking and crushing old tea leaves, this embodiment takes the following measures:

[0030] like Figure 4 , Figure 5 As shown, the crawler tea picking machine also includes a crushing box 7, which is mounted on the top of the platform 21. The crushing box 7 is located below the higher end of the conveying pipe 5. The feed port of the crushing box 7 is connected to the conveying pipe 5 through a second cloth bag. One end of the second cloth bag is put on the conveying pipe 5 and tied with wire, and the other end of the second cloth bag is put on the feed port of the crushing box 7 and also tied with wire. The storage bin 6 is located below the discharge port of the crushing box 7, and the feed port of the storage bin 6 is completely connected to the discharge port of the crushing box 7.

[0031] With this design, the conveying pipe 5 directly conveys the tea leaves to the crushing box 7 , and the crushing box 7 is used to crush the tea leaves on site, and the crushed tea leaves are collected in the storage bin 6 .

[0032] Considering that the storage space of the storage bin 6 is also limited, in order to facilitate the release of the tea leaves in the storage bin 6 so that the tea picking machine can continue to operate, the present embodiment adopts the following measures: Figure 4 , Figure 5 As shown, two telescopic components 8 are provided at the bottom of the platform 21. The power source of the telescopic components 8 can be driven by an oil cylinder, an air cylinder or a hydraulic cylinder. A clamp 81 is provided at the movable end of each telescopic component 8. A valve and a third cloth bag are provided at the discharge port at the bottom of the storage bin 6. The valve is used to control the opening and closing of the discharge port of the storage bin 6. One end of the third cloth bag is sleeved on the discharge port of the storage bin 6 and tied with wire. The other end of the third cloth bag is the discharge port. Two clamps 81 are respectively located on both sides of the third cloth bag, and the clamps 81 clamp the discharge end of the third cloth bag.

[0033] A tea collecting vehicle is parked at the end of the tea table in advance. When the tea plucking machine moves to the tea collecting vehicle, the two telescopic components 8 are extended at the same time, thereby extending the discharge end of the cloth bag to the outside of the tea plucking machine and above the tea collecting vehicle; then the valve opens, and the storage bin 6 begins to release the tea leaves, which are finally released into the tea collecting vehicle under the guidance of the third cloth bag; after the storage bin 6 is emptied, the valve is closed again, and the two telescopic components 8 are shortened at the same time, and the discharge end of the third cloth bag shrinks to its original position.

[0034] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
