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 produce leaves. When the buds of plum blossoms are seven mature, the adhesion of the buds on the branches will be relatively low. At this time, using the picking device disclosed in the present invention has a better use effect.

At the beginning of picking, lay a layer of plastic bag under the plum tree (that is, the above-mentioned collection bag, of course, a flat film or a flat cloth layer can be used instead) to collect the plum buds; when collecting, the mechanical body of the picking equipment 3 is moved to the side of the plum tree, and the height of the up and down movement of the picking device 1 is manually controlled according to the actual situation. When collecting, the rotating drum 13 at the collecting end is driven by the drive motor 14 to rotate the pulley (the pulley here is arranged). On the rotating drum 13), in order to reduce the wear caused by the residue of tree branches falling on the belt when the belt is collected, there will be a protective casing on the belt for protection.

When the rotating drum 13 is rotating (of course, the rotating drum 13 can also be approached in a stationary state) approaching the branch, the branch will be placed in the area between the two limit rods 1241 inclined at the front end of the picking rod, and the rotating drum 13 will rotate the branches. The flower buds next to it will also fall, and at the same time, when the picking rod on the rotating drum 13 touches the branches, it will also cause the branches to vibrate, which will also cause the flower buds to fall. The picking rod will automatically avoid when it encounters a thick branch, and can also automatically rebound when it is separated from the 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 driving motor 14 is required to control the rotating drum 13 according to the growth of the branches. direction of rotation, so as to better collect flower buds.

Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner, as long as various insubstantial improvements made by adopting the method concept and technical solution of the present invention are all within the protection scope of the present invention.
