Embodiment one

The taro double-shaking soil harvester of the present embodiment is shown in Figures 1 to 4, wherein the frame 2 is supported on the ground wheels, and is mainly composed of a horizontal U-shaped frame and an approximate large-shaped support frame fixed on the top. The earth scraper 25 is installed below the front part of the frame 2, and the soil shaking mechanism is installed after the earth scraper 25. The soil shaking mechanism contains a front soil shaking shovel 21 and a rear soil shaking shovel 17 connected to each other.

The bottom of the front end of the front soil shaking shovel 21 is hinged on the lower end of the T-shaped connecting plate 24 fixed on the frame, and the upper end of the swing arm 21-1 extending upward on both sides of the front end is hinged with the front end of the short connecting rod 21-2. The rear end of the short connecting rod 21-2 is hinged with the middle part of the door-shaped swing link 6-1 of the main swing frame 6. Both sides of the upper part of the swing rod 6-1 of the main swing frame 6 are hinged and supported on the upper part of the connecting plate 24 by hinge bolts 6-2; thus the front soil shaking shovel essentially becomes a double swing frame composed of a frame, a short connecting rod and a main swing frame. One of the connecting frame rockers of the rod mechanism, when working, its rear part does a reciprocating swing with the hinge fulcrum at the lower end of the connecting plate as the swing center, so as to realize the bumping and shaking of the soil.

In this way, the rear soil shaking shovel essentially becomes the connecting rod in the double rocker mechanism composed of the frame, the main swing frame, and the vertical rocker arm. When working, it makes a planar movement that approximates the horizontal long axis elliptical trajectory to realize sieving and shaking soil. Moreover, by adjusting the distance between the upper and lower lockable inserting positions of the adjusting rod, not only can the fixed position of the horizontal support arm relative to the frame be changed, but also the hinged position of the upper end of the vertical rocker arm of the soil shaking shovel relative to the frame can be adjusted. , to achieve the purpose of changing the approximate elliptical motion trajectory of the soil shaking shovel, and can adjust the inclination angle of the long axis of the approximate elliptical motion trajectory relative to the horizontal line, so that the effects of sieving, shaking soil and bumping transportation are ideal.

In this embodiment, a triangular suspension traction mechanism is used to articulate at the rear of the tractor. The power source of the tractor is connected to the tractor by the universal joint 1 through the sprocket combination 33 respectively through the same direction chain transmission 45, chain transmission 46 and bevel gear transmission 47 and supported on the tractor. The rotating shaft of the crank 41 on the frame is connected with the transmission of the vertical cutter drive shaft 48.
