specific;

The picking equipment disclosed in the present invention mainly includes a picking device 1 , a mechanical arm assembly 2 and a mechanical vehicle body 3 .

Plum blossoms bloom first and then grow leaves. When the buds of plum blossoms reach seven maturity, the adhesion of the buds on the branches will be relatively low. At this time, the picking equipment disclosed by the invention has a better use effect.

At the beginning of picking, lay a layer of plastic bags under the plum tree (that is, the above-mentioned collection bag, of course, a flat film, a flat cloth layer can also be used to replace) to collect the plum blossom buds; the mechanical car body of the picking equipment 3 is shifted to the side of the plum blossom tree, and the height of the up and down movement of the picking device 1 is manually controlled according to the actual situation. On the rotating drum 13), in order to reduce the wear and tear caused by the residue of branches falling on the belt when the belt is collected, there will be a protective shell on the belt for protection.

In addition, in the actual layout, in order to fit the actual situation of the branches, there are three lengths of picking mechanisms 12 on the rotating drum 13, which are respectively recorded as long, medium and short; long and medium may encounter thick branches, so there is a rotation Institution 123, I can't meet the short ones, so I don't have any.

When the rotating drum 13 rotates (certainly, the rotating drum 13 can also approach in a stationary state) close to the branches, the branches will ride on the area between the two limit rods 1241 inclined at the front end of the picking rod, and the rotating drum 13 rotates the branches. The flower bud next to it also can fall, and also can cause the vibration of branch when the picking bar on the rotating drum 13 hits branch simultaneously, also can cause the drop of flower bud like this, in order not to destroy branch and machinery when running into thick branch, The picking rod will automatically avoid when it encounters a thick branch, and it can also automatically rebound when it breaks away from a thick branch, without affecting the subsequent work;

In addition, some branches will grow obliquely downward. In order to facilitate the removal of flower buds on such branches, the drive motor 14 is required to control the rotating drum 13 in forward and reverse directions according to the growth of the branches. The direction of operation, so as to better collect flower buds.

Apparently, the specific implementation of the present invention is not limited by the above methods, as long as various insubstantial improvements are made by adopting the method concept and technical solutions of the present invention, they all fall within the protection scope of the present invention.
