Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1, fig. 2 and fig. 3, a suspension type single-blade shaft rotary cultivator comprises a frame 1, a speed reducer 2 is fixedly connected to the middle position above the frame 1, the speed reducer 2 is symmetrically connected to a first output shaft 3 and a second output shaft 4, one end of the outer side of the first output shaft 3 and one end of the outer side of the second output shaft 4 are respectively connected to a first chain wheel 5 and a second chain wheel 6, a blade shaft 7 is further arranged below the frame 1, two ends of the blade shaft 7 are respectively and fixedly connected to a third chain wheel 8 and a fourth chain wheel 9, a plurality of stabilizing frames 10 are further uniformly fixed on the blade shaft 7, a plurality of support shafts 11 are arranged on the stabilizing frames 10, and a plurality of rotary. The first chain wheel 5 is connected with the third chain wheel 8 through a chain 13, and the second chain wheel 6 is connected with the fourth chain wheel 9 through the chain 13. The stabilizing frame 10 is in a shape of a double ring, a plurality of round holes are uniformly formed in the large ring 14 along the circumferential direction, and the large ring 14 is connected with the small ring 15 through a plurality of radial plates 16. Frame 1 rear side still is equipped with two pneumatic cylinders 17, and pneumatic cylinder 17 stretches out the end and all articulates on installation axle 18, and installation axle 18 both sides fixed connection first connecting rod 19 and second connecting rod 20, the articulated compacting roller 21 of the one end of first connecting rod 19 and second connecting rod 20, the other end of first connecting rod 19 and second connecting rod 20 articulates in frame 1.

In the above scheme, before use, the three hitching points 22 on the frame 1 are installed on the tractor three-point hitch, the power output shaft of the tractor is connected with the input shaft of the speed reducer 2, then the user outputs the power of the tractor to the speed reducer 2, the speed reducer 2 drives the first chain wheel 5 and the second chain wheel 6 to rotate through the first output shaft 3 and the second output shaft 4, the first chain wheel 5 and the second chain wheel 6 drive the third chain wheel 8 and the fourth chain wheel 9 to rotate through the chain 13 respectively, so that the cutter shaft 7 rotates, thereby driving the rotary blade 12 installed on the supporting shaft 11 to work, during rotary tillage operation, the user adjusts the three-point hitch of the rotary cultivator by adjusting the hitch mechanism of the tractor, so that the rotary blade 12 carries out rotary tillage on soil, the user drives the first connecting rod 19 and the second connecting rod 20 to rotate around the pin joint fixed on the frame, thereby adjusting the lifting of the press roller 21 and realizing the press of soft soil after rotary tillage.
