Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.The utility model is not limited to following examples.
As shown in Figure 1, Figure 2 and Figure 4, Fig. 1 and Fig. 4 are respectively structural representation and the schematic three dimensional views of potato harvester of the present utility model, the mainframe vertical view that Fig. 2 is potato harvester of the present utility model.Potato harvester of the present utility model comprises mainframe 2, and mainframe 2 is a rectangular frame, and the direction of advance of facility of take is the place ahead, and this mainframe 2 is with being positioned at anterior first crossbeam 12 and being positioned at the second cross beam 13 at middle part; On Liang Ge angle, the rear of mainframe 2, can also be equipped with two rectangular tubes as support bar, so that facility are steadily placed when not working; Described mainframe 2 can be welded by rectangular tube.
Middle part, the place ahead at mainframe 2 is furnished with the three point linkage 1 articulated with the peripheral hardware tractor; Falsework 3 is connected on first crossbeam 12 by bearing pin, and can take bearing pin and swing within the specific limits as end points.
Potato harvester of the present utility model also comprises working cell, and wherein, described working cell comprises transmission system, profiling depth stop device and digger blade assembly.
In described transmission system, gearbox 7 is arranged in the middle part of the second cross beam 13 of mainframe 2, and the front portion of described gearbox 7 is connected with rotating shaft 9, and this rotating shaft 9 is connected with the tractor output shaft of tractor; The both sides of described gearbox 7 are connected with output shaft of gear-box by universal joint, and the bearing block of these output shaft of gear-box both sides is fixed on the both sides of the second cross beam 13 of mainframe 2, can move freely within the specific limits; One end of connecting rod 8 is connected on this output shaft of gear-box, and the other end is connected with the middle part of falsework 3 by bent axle.Like this, the outputting power of tractor is sent to gearbox 7 by rotating shaft 9, be sent to the output shaft of gear-box of gearbox both sides after the break-in of bevel gear in gearbox 7 and speed change, output shaft of gear-box drivening rod 8, connecting rod 8 drives falsework 3 and swings up and down under the effect of bent axle; Therefore, falsework 3 can swing within the specific limits around the first crossbeam 12 of mainframe 2.
