[0068] A plurality of second blocking rods 530, one end of which passes through the second positioning plate 520 and is connected to the first positioning plate 510

[0069] Fixedly connected, the first stopper 410 is located within the range of the soil screening shovel 500;

[0070] Lifting device, including

[0071] The rotating sleeve 620 is rotatably disposed on the frame 100;

[0072] A plurality of connecting frames 630 are evenly fixedly disposed on the rear end wall of the rotating sleeve 620;

[0073] A plurality of limiting rings 640 are respectively fixedly sleeved on the outer walls of the circular rings formed by the plurality of connecting frames 630;

The end of the second connecting rod 550 in the soil screening shovel 500 passes through the rotating sleeve 620 and corresponds to the discharging trough 660, so as to deliver the potatoes after the soil is screened into the discharging trough 660.

[0075] The partition 670 is in an arc shape and is disposed between the two links 650 to prevent the potatoes from falling during the lifting process;

[0076] Two baffles 710 are arranged on the frame 100 in parallel with each other;

[0078] This embodiment is implemented as follows:

[0079] When the present application is in use, the first mounting frame 110 and the second mounting frame 120 on the frame 100 are connected to the tractor head, and the output end of the tractor head is connected to the spline 300, driving the spline 300 to rotate, so that the spline 300 drives the crank 310 to rotate, and then drives the primary rocker 320 to perform an undulating up and down reciprocating motion, and the movement of the primary rocker 320 is transmitted to the secondary rocker 330, so that it also performs an up and down reciprocating motion, and the movement state of the secondary rocker 330 will prompt the rocking plate 340 to move back and forth up and down, thereby driving the front positioning plate 350 of the soil screening shovel to move back and forth up and down, so that the first connecting rod 360 drives the digging plate connecting plate 420 The digging plate 400 reciprocates up and down, and there is a difference in the fixed heights of the front and rear ends. Therefore, when the digging plate connecting plate 420 and the first connecting rod 360 reciprocate up and down, the digging plate 400 will reciprocate in the front and rear directions, so that the potatoes and soil can be dug out and move toward the first blocking rod 410, so as to fall on the second blocking rod 530; similarly, the second positioning plate 520 is connected to the frame 100 through the cooperation of the rear positioning plate 540 of the soil screening shovel and the second connecting rod 550. When the front positioning plate 350 of the soil screening shovel reciprocates up and down, the soil screening shovel 500 will also reciprocate in the front and rear directions, thereby realizing the function of screening soil, and the digging plate 400 realizes the function of digging;

[0080] The forward and backward reciprocating motion of the soil screening shovel 500 will send the potatoes after screening to the discharge trough 660. The rotation of the rotating sleeve 620 will drive the connecting frame 630, the limiting ring 640, the chain 650, and the partition 670 to rotate. The potatoes in the placement trough 660 can rotate with the placement trough 660. Due to the existence of the partition 670, the potatoes will not fall during the upward transportation. The outer wall of the partition 670 corresponds to at least one connecting frame 630. Once the potatoes move to the highest point, they will not be restricted by the partition 670, and will fall from the placement trough 660 onto the conveyor belt 700 and be transported backward through the conveyor belt 700.

[0081] See also Figure 1 , 2 , 3, 4, 9, a plurality of rotating columns 610 are rotatably arranged on the frame 100, a rubber roller 611 is arranged at one end of the plurality of rotating columns 610, the plurality of rubber rollers 611 surround the rotating sleeve 620, a limiting groove 621 is provided on the outer circumferential wall of the rotating sleeve 620, and the plurality of rubber rollers 611 extend into the limiting groove 621 respectively, and one of the rotating columns 610 is a driving column.

[0082] The rubber roller 611 arranged on the plurality of rotating columns 610 on the frame 100 can extend into the limiting groove 621 of the rotating sleeve 620, so as to position the rotating sleeve 620. At the same time, one rotating column 610 can rotate to drive a rubber roller 611 to rotate, so that the rubber roller 611 drives the rotating sleeve 620 to rotate.

[0083] See also Figure 1 , 2 , 3, 4, 9, a transmission rod 920 is rotatably provided on the frame 100, one end of the transmission rod 920 is transmission-connected to the spline 300 through a first transmission chain 910, and the other end of the transmission rod 920 is transmission-connected to a rotating column 610 through a fourth transmission chain 970.

[0084] The first transmission chain 910 is provided so that the spline 300 can drive the transmission rod 920 to rotate, and the transmission rod 920 drives a rotating column 610 to rotate through the fourth transmission chain 970 .
