Description

An electric telescopic torque increasing device

technical field

The utility model relates to the technical field of picking machines, in particular to an electric telescopic twist-increasing device.

Background technique

At present, most of the flower buds and tea fruits are collected manually, and the time is concentrated and the time is short, which requires a lot of manpower and material resources. Especially for the collection of flower buds with medicinal value, manual operations are used. There are some disadvantages in manual collection: First, the efficiency of manual collection is relatively low. Generally, the amount of flower buds collected by one person in one hour is 1 to 2 catties; second, manual collection requires people to use their fingers to pick. After a long picking time, it will cause backache. Painful hands, tired easily.

Other large-scale mechanical vibration picking equipment, by shaking the branches and branches to make the fruit fall off, and collect the fruit at the same time. This method of picking has great damage to the fruit tree itself, and the fruit drop is large, so the implementation is not strong. The other is a small picking equipment, which sucks or rolls the fruit into the picking equipment through negative pressure or pulling teeth, so that it is separated from the branches. In the negative pressure suction picking method, the small suction pressure cannot make the fruit successfully separate from the branches and complete the picking. The large suction pressure will cause damage to the fruit tree and fruit, and at the same time, the leaves and branches will be sucked in and the fruit will be cut. In the picking method of pulling-in teeth, since the catch port of the equipment cannot be adjusted, it is not convenient for the equipment to capture the fruit, and the pulling-in force of the teeth cannot be adjusted, which is easy to damage the branches and fruits.
