during picking, a power supply of the wolfberry picking vehicle is started, the vibration generator 334 is started to generate mixed vibration, and the rotating drum is driven to perform reciprocating linear and horizontal transverse motion along a limited direction under the action of the fixed arm 331 and the first spring 332 and the second spring 333;

meanwhile, the picking vehicle body 100 moves under the traction of an engine, when the picking vehicle body 100 walks between the medlar rows, the branch supporting device 200 introduces medlar branches into the picking device 300, the combing and brushing teeth 322 on the rotating shaft continuously vibrate up and down in the axial direction and left and right in the horizontal direction, comb and brush the fruit branches, the amplitude and frequency of the vibration generator 334 are adjusted by a driver, so that the mature medlar fruits are combed and brushed and vibrated to fall onto the collecting plate 400 and are guided by the inclined collecting plate 400, the fruits are temporarily accumulated on the lower side of the collecting plate 400, and the picked medlar fruits further enter the loading box of the picking vehicle body 100 through the guidance of the transmission system 500;

the horizontal transmission section 521 is correspondingly butted with the lower side of the collection plate 400 in the inclined direction, the medlar fruits and impurities on one side of the collection plate 400 enter the hopper 513, the chain 511 drives the hopper 513 to continuously and circularly transmit, the medlar fruits and other impurities loaded in the hopper 513 rise through the lifting transmission section 522, the medlar fruits and other impurities are thrown onto the conveying mesh belt 501 in the discharging section 523, and the medlar, the blades and other impurities are separated by utilizing the wind power action of the air separator 600;

the wolfberry fruits with separated leaves are thrown into a loading box at the moving tail end of the conveying mesh belt 501 under the transmission guide of the conveying mesh belt 501;

thus, the picking and collection of the mature medlar can be completed when the vehicle continuously runs.

The invention has the beneficial effects that:

(4) Conveying device's the section of unloading corresponds and is provided with conveying mesh belt, and conveying mesh belt position correspondence is provided with air separator, and air separator is used for separating impurity such as matrimony vine and blade, adopts the selection by winnowing mode of blowing the updraft ventilator down, reduces the destruction to the fruit when the selection by winnowing, increases the fruit leaf separation effect of selection by winnowing.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
