Description

portable electric tea picker

technical field

The utility model relates to an agricultural machine, in particular to a portable electric tea picking machine for picking tea leaves.

Background technique

In my country, most of the tea picking relies on manual picking. There are very few people who use large imported motorized tea picking machines, and some people use domestic tea picking machines powered by diesel engines. The above machines need two When three people are required to operate, the weight of the model is relatively heavy, the cost is high, the requirement for the flatness of the tea forest is high, and the labor intensity of the operator is relatively high. Some people have invented some relatively small motorized tea-picking machines at present, such as single-person-operated portable operation models. Although the picking efficiency of this type of tea-picking machines has been improved, there are still some problems. One is for tea trees and The tea leaves have a high damage rate and a high fragment rate. The second is that the operating surface is still wide, which makes the picking work inconvenient. smooth. In order to solve these problems, the present inventor has improved the structure of the existing tea picking machine, and applied for a Chinese patent on a portable tea picking machine, patent number: 200720105152.3 publication (announcement) number: CN201115348, abstract: a portable tea picking machine , including a leaf picking box, a tea picker, a power supply, an electric motor, a power switch and a tea collection bag, the front end of the leaf picking box is equipped with a tea picker, the tea picker is equipped with a blade, the blade is fastened on the motor shaft, and the power supply is connected to the motor through a wire. The tea picking device is composed of upper and lower comb-type leaf guide plates and a blade in the middle. The handle is above the leaf picking box. The motor is installed inside the handle. The motor shaft passes through the leaf picking box to reach the tea picking device. The blade is fixed on the motor shaft. The power switch is installed on The outer edge of the handle is connected with the motor and the power supply. There is a tea collection bag behind the leaf picking box. When in use, connect the DC motor to the power supply, start the manual switch, hold the tea picking machine, and let the comb-type leaf guide plate insert In the tea bushes, the blade is aimed at the tea seedlings or tender tea leaves to cut, so that the tea leaves continuously flow into the dense mesh flexible mesh bag, that is, the operation of tea picking can be realized.

But the above-mentioned portable tea-picking machine produced by the inventor is tested in the tea garden, and it is found that there are some shortcomings, 1, because the motor main shaft is directly fixed on the comb-type guide vane plate with nuts, so the comb-type guide vane plate swings after the motor works, The main shaft of the motor shakes, and the vibration of the whole machine is relatively large; 2. The original machine uses ultra-thin blades, which may collapse when picking tea leaves and encountering old tea stems; 3. The rated power of the motor is slightly lower (less than 4 watts) , the terminal voltage is below 6V), which affects the efficiency of work.

Contents of the invention

The purpose of the utility model is to solve the deficiencies of the prior art, and provide a portable electric tea picking machine with light weight, wide adaptability, low debris rate, small vibration during work, smooth tea discharge and higher work efficiency.

In order to solve the above-mentioned technical problems, the solution proposed by the utility model is: the portable electric tea picking machine includes a power supply, a motor, a leaf picking box and a tea picking device, the motor is installed inside the handle, the tea picking box is equipped with a tea picking device at the front end of the leaf picking box, and the leaf picking box There is a tea collection bag at the back of the tea picker. The tea picker is composed of a top plate, a comb-type guide leaf plate and a blade in the middle. The motor shaft passes through the leaf picking box to reach the tea picker. The blade is fastened on the motor shaft. Bearings are installed on the lower end of the lower end and the top of the comb-type guide vane plate, and the motor main shaft passes through the top plate of the leaf picking box, the bearing, and the comb-type guide vane plate and is tightened with nuts. Blades, they are fastened together on the base plate of the leaf picking box with screws and nuts.

The above-mentioned blade adopts a curved blade with good toughness and rigidity, or a rectangular blade, so that there will be no cracking when picking tea leaves and encountering old tea stems.

The above-mentioned power supply can adopt a 6-24V storage battery or storage battery, and the power of the motor can be 4-60W, so that the working time is long and the efficiency is high.

The above-described leaf picking box, comb-type leaf guide plate, and the tea collection bag have the same structure as the inventor's patent (patent number: 200720105152.3), and will not be described in detail here.

Compared with the prior art, the outstanding substantive features and remarkable progress of the utility model are:

1. This device has low fragmentation rate of tea picking, small vibration during operation, smooth tea discharge, high work efficiency, simple structure, low manufacturing precision requirements, and low cost.
