Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of power pulverizer of smooth effective and high efficiency.
The utility model is achieved through the following technical solutions: a kind of power pulverizer, comprise hitch frame, gearbox and hack rotor casing, hitch frame be fixed on hack rotor casing above, gearbox be connected hack rotor casing above, the back of hack rotor casing is connected with soil-suppressing board, many group vertical rotors are set in the lower end of hack rotor casing, many group vertical rotors are arranged side by side, every group of vertical rotor has two rake cuttves, two rake cuttves are " door " shape and are provided with, and the radially angle of every two adjacent groups rake cutter is 15 °～30 °.
In the such scheme, overlap for the operating area that makes per two adjacent rake cuttves produces, can not leak rake during the arable land, the radius of turn of every group of rake cutter is greater than 1/2nd two adjacent groups hack centre of rotor distances.
In the such scheme, do not throw to ground surface for making wet soil too much in the process of smooth field, the blade of described rake cutter recedes with rake cutter direction of rotation, with vertical direction angle is arranged.
A kind of power pulverizer of the utility model compared with prior art, its beneficial effect is:
1, this power pulverizer operation time rake cutter is to horizontally rotate, and blade recedes, and so just can not make too much wet soil throwing to ground, so the degradation rate height of soil block, land readjustment is effective, levels land and finishes a high efficiency;
2, there is certain lap the operating area of per two adjacent rake cuttves, can not leak rake, and the adjacent rotor direction of rotation is opposite, the unit stable working.
