Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further. The utility model is not limited to the following examples.

As shown in Fig. 1, Fig. 2 and Fig. 4, Fig. 1 and Fig. 4 are respectively the structural representation and the three-dimensional schematic diagram of the potato harvester of the present utility model, and Fig. 2 is the top view of the mainframe of the potato harvester of the present utility model. The potato harvester of the present utility model comprises a main frame 2, the main frame 2 is a rectangular frame, and the forward direction of the implement is the front, and the main frame 2 has a first crossbeam 12 positioned at the front and a second crossbeam 13 positioned at the middle ; On the two corners of the rear of the main frame 2, two rectangular tubes can also be equipped as support rods, so that the machine tool can be placed stably when not working; the main frame 2 can be welded by rectangular tubes.

In the middle of the front of the main frame 2 is arranged a three-point suspension device 1 articulated with the peripheral tractor; the working frame 3 is connected to the first beam 12 through a pin shaft, and can swing within a certain range with the pin shaft as an end point.

The potato harvester of the utility model also includes a working unit, wherein the working unit includes a transmission system, a profiling depth limiting device and a digging shovel assembly.

In the transmission system, the gearbox 7 is arranged in the middle of the second beam 13 of the main frame 2, and the front part of the gearbox 7 is connected with a rotating shaft 9, which is connected with the tractor output shaft of the tractor; the gearbox The two sides of 7 are connected with the transmission output shaft through the universal joint, and the bearing seats on both sides of the transmission output shaft are fixed on the two sides of the second beam 13 of the main frame 2, and can move freely within a certain range; the connecting rod 8 One end of is connected on this gearbox output shaft, and the other end is connected with the middle part of working frame 3 by crankshaft.
