Portable electric tea-leaf picking device

Abstract

The invention discloses a portable electric tea-picking machine, comprising a tea collecting bucket with handle, a DC micro motor that is mounted in the tea collecting bucket, has a downwards mounted rotor and passes through the bottom plate of the tea collecting bucket, a storage cell connected with the DC micro motor through lead, an eccentric mechanism sleeved on the DC micro motor rotor, a comb-shaped fixing blade, and a swinging blade that cuts off tea by cooperating with the fixing blade. The fixing blade is mounted below the bottom plate of the opening of the tea collecting bucket, with outward cutter tooth. The swinging blade is mounted below the fixing blade, with outward cutter tooth. The fixing blade is moveably connected together with the swinging blade through a connecting component. The cutter teeth of two blades are overlapped The rear end of the swinging blade is slidably connected to the eccentric mechanism so as to slide in reciprocating and linear, such that the cutter teeth of two blades are mutually and alternately overlapped. The tea entering the cutter tooth is cut off and falls into the tea collecting bucket. The tea-picking machine has advantages of legerity, portability, flexible operation, and high speed of picking tea.

Description

technical field [0001] The invention relates to an electric tea-picking tool, especially a portable electric tea-picking machine which is powered by a storage battery and driven by a DC micro-motor to drive blades to cut and collect tea leaves. Background technique [0002] As we all know, there is a very long history of growing and drinking tea in our country. For a long time, drinking tea has become a habit and an indispensable part of life. However, there is not much improvement in the harvesting of tea at present. Most of the tea farmers still use the ancient method of manual picking. Manual picking is not only labor-intensive, but also slow, and the picking is not clean, causing old tea to remain on the tea tree, thereby reducing the quality of the next season's tea and wasting tea resources. . With the continuous expansion of tea planting area, many tea farmers have to pay high tea picking costs due to the shortage of tea pickers during the harvest season. [0003] A...

Problems solved by technology

[0003] At present, a large-scale gasoline tea picking machine has appeared on the market. The tea picking speed of this tea picking machine is high and the efficiency is high, which greatly alleviates the problem of "difficult tea picking" for tea farmers. However, this tea picking machine also has its own problems. Some defects; firstly; most of the tea trees grow in mountainous areas, where the mountains are high and the roads are steep, and the tea farmers have to carry the entire gasoline engine on their backs. It is more difficult for tea workers to operate. Secondly, there are many mechanical failures, difficult maintenance, manual starting, etc. The engine is often difficult or impossible to start due to carbon deposits in spark plugs, blockage of oil passages, or excessive oil, which causes "choking" oil, etc. Again; it cannot be operated by a single person. In addition to the operator, several people need to drag the large cloth bag behind the tea picking machine to collect the cut tea leaves. In addition, the exhaust gas from the engine not only pollutes the environment but also pollutes the tea itself, reducing the quality of the tea.

[0004] In order to overcome the defects of the gasoline tea picking machine; many people are researching more practical and lighter electric tea picking machines; as the patent of CN2321204 discloses a low-power electric tea picking machine, which adopts The battery powers the small-power motor to drive the horizontally rotating cutting blade to pick tea, which makes the tea picking machine much lighter and more flexible. Because the blade is used to pick and cut tea at high speed, but high-speed operation requires a certain period of time after the motor is started. The rated speed can only be reached, and the picking operation can only be carried out after the speed is stable. It is difficult for the tea picking machine to achieve effective control of picking and opening, stopping and closing. It is consumed in a large amount in a short period of time, and the blades running at high speed will cause a large number of whisker-like fragments to appear in the picked tea leaves, and the tea leaves will not be collected completely, thereby reducing the yield and quality of the tea leaves; A DC electric tea picking machine, which is connected to the motor rotor through an eccentric part and then connected to the upper blade to slide back and forth in a straight line, so that the teeth of the upper and lower blades overlap each other alternately, so that the tea leaves that enter the blade teeth are cut off And it is collected by the collection basket, and the running speed of the blade is controlled by such a structure. The disadvantage of this design is that the tea leaves or tea in the collection frame are more likely to block the sliding of the upper blade, and the friction between the blades increases, making the sliding If the tea leaves or tea are more blocked, it will cause jamming and the upper blade cannot swing. In addition, because the upper blade slides back and forth, it is easy to scratch the tea leaves in the frame, so it is necessary to further improve the existing tea picking machine. , making it more practical and more conducive to popularization
