[0032] Specifically, it includes a transport system 100, including a gantry main frame 101 and four sleeve inner columns 102, and the four sleeve inner columns 102 are respectively movably sleeved inside the four legs of the gantry main frame 101, and the bottoms of two sleeve inner columns 102 located on the same side of the gantry main frame 101 among the four sleeve inner columns 102 are installed with a crawler chassis 105, the top of the gantry main frame 101 is fixedly connected with a carrying platform 300, the top of the carrying platform 300 is fixedly connected with a seat 200, the top of the carrying platform 300 is provided with a power system 400 and a control system 600, and the back of the gantry main frame 101 is provided with a screening system 800, and the crawler chassis 105 can be set to make the harvester run freely on soft and uneven land, thereby improving the flexibility of the harvester; The collecting system 700 is located at the bottom of the picking system 500. There are two collecting systems 700, two picking systems 500 and two screening systems 800, and they are all symmetrically arranged. The symmetrical arrangement can realize the operation on both sides of the wolfberry tree at the same time, thereby improving the picking efficiency. The four legs of the gantry main frame 101 are all fixedly connected with upper fixing pins 101a, and the outsides of the four upper fixing pins 101a are all rotatably connected with lifting hydraulic cylinders 103. The insides of the four sleeve inner columns 102 are all fixedly connected with lower fixing pins 102a, and the output ends of the four lifting hydraulic cylinders 103 are respectively rotatably connected to the outsides of the corresponding lower fixing pins 102a. The height of the gantry main frame 101 can be adjusted by telescoping the four lifting hydraulic cylinders 103, so that wolfberry trees of different heights can be operated. The picking system 500 includes an outer frame 501 and a first mounting frame 503 located inside the gantry main frame 101. Four slides 510 are fixedly connected to the top of the outer frame 501. A first insertion hydraulic cylinder 507 and two mutually parallel slide rails 104 are fixedly connected to the inner top of the gantry main frame 101. The four slides 510 are respectively slidably connected to the outside of the corresponding slide rails 104. The outer frame 501 is fixedly connected to the output end of the first insertion hydraulic cylinder 507. The distance between the two picking systems 500 can be adjusted by telescoping the first insertion hydraulic cylinder 507, so that wolfberry trees of different widths can be operated. Two transverse vibration guide rails 502 are fixedly connected inside the outer frame 501. The first mounting frame 503 is rotatably connected to one side facing the outside of the gantry main frame 101 with four pulleys 504 distributed in a rectangular shape, and the four pulleys 504 roll on the outside of the corresponding vibration guide rails 502 respectively. The four pulleys 504 can be set to fix the first mounting frame 503 on the outside of the two vibration guide rails 502, and at the same time, the first mounting frame 503 can roll horizontally on the vibration guide rails 502. Both sides of the first mounting frame 503 are fixedly connected with a slide bar 505, and the outer side of the slide bar 505 is slidably sleeved with a second mounting frame 506. The second mounting frame 506 and the first mounting frame 503 are vertically installed with densely matrix-distributed pickers 509 through hollow screws on the inner side of the gantry main frame 101.

By setting the second insertion hydraulic cylinder 506c, the second mounting frame 506 can be separated from the first mounting frame 503 and then inserted into the wolfberry tree with the corresponding picker 509 first, thereby avoiding the pickers 509 being too dense and causing excessive resistance during the insertion process.

[0033] Furthermore, the picker 509 includes a picking bar 509a, one end of which is fixedly connected to a connecting head 509b, and the other end of the picking bar 509a is movably connected to a guide head 509c, and the guide head 509c is a silicone sleeve.
