Description

A pick device for litchi is planted

Technical Field

The utility model relates to an agricultural utensil technical field especially relates to a pick device for litchi is planted.

Background

Litchi is a fruit widely planted in south China, and is a high-quality fruit variety, and the cultivation area and yield of litchi in China are the top of the whole world.

Litchi fruit trees are tall trees. In the season of abundant litchi production, most fruits of litchi are intensively ripe, and the litchi is relatively dense, so in the prior art, an economical picking mode is still manual picking after manual climbing or branch pulling, and the picking mode is favorable for fruit quality and tree branches.

However, in actual picking, some single fruits are still far away from the dense and productive area, and if the single fruit picking is completed by the above picking mode, the influence on the picking efficiency is very large. At present, aiming at the single fruits, a plastic cylinder with a notch is adopted, the size of the notch is smaller than that of the litchi fruits, a support rod is arranged on the plastic cylinder and serves as an extension rod, the extension rod is held by the lower end of a picker, the litchi fruits are separated from a fruit handle in a pulling mode after being guided into the notch by the notch, and the separated fruits fall into a pocket net connected to the lower end of the plastic cylinder.

Aiming at the above single litchi fruit picking mode, the quality of a single litchi fruit body is very high, but the general fruit peel of the obtained fruit is damaged, and the influence on the quality of the fruit on the market is large.

SUMMERY OF THE UTILITY MODEL

To the further great technical problem of the influence of existing in the current litchi single fruit picking mode to fruit quality on the market that provides, the utility model provides a pick device for litchi is planted. The single litchi picking device is simple in structure, single litchi picking can be conveniently completed, and the quality of fruits is not influenced in the picking process.

To the above problem, the utility model provides a pick device for litchi is planted solves the problem through following technical essential: the picking device for litchi planting comprises a support rod, a plastic cylinder connected to the front end of the support rod, and a pocket net connected to the bottom of the plastic cylinder, wherein the plastic cylinder is further provided with a gap with an opening end starting from the upper end of the plastic cylinder;

the scissors are characterized by further comprising a return spring, wherein one end of the return spring acts on the movable scissors body, the other end of the return spring acts on the fixed scissors body, and in the process that the opening of the scissors is enlarged, the return spring generates elastic deformation with an increasing stretching state;

and the scissors also comprise a pull rope with one end connected with the free end of the movable scissors body.

As mentioned above, when the scheme is used, the stay bar is used as an extension bar, and a user holds the lower end of the stay bar to use the device; the single litchi fruit is introduced into the plastic cylinder from the upper end of the plastic cylinder, and the branch connected with the litchi fruit is embedded into the gap, at the moment, the scissor opening of the scissors is in an open state: the movable scissor body is pulled through the pull rope, and the branches simultaneously pass through the scissor edge. And then, the pull rope is released, the movable scissor body rotates around the hinge shaft under the elastic force of the return spring, and the scissors perform shearing action to shear the branches. The fruit then falls into the net bag and is collected.

In the process, the picking device solves the problems that the fruit peel is damaged and the quality of the fruit on the market is influenced because the litchi is restrained by the inner side of the plastic cylinder with the notch and the litchi fruit is forced to be separated from the branch by the pulling force generated by the pulling action in the traditional picking device.

Preferably, in order to avoid that the branches slide out of the cutting opening under the thrust of the cutting edge of the scissors when the scissors are carried out, the arrangement is that: at least one of the cutting edges of the fixed scissors body and the movable scissors body is arranged to be zigzag.
