Abstract
The invention discloses a straw turnover rotary cultivator capable of avoiding straw twining. The straw turnover rotary cultivator capable of avoiding straw twining comprises a gear box fixed to a shell body, a power transmission box body and a supporting arm body. The lower portion of the power transmission box body and the lower portion of the supporting arm body support the two ends of a cutter roll shaft, a plurality of rotary cultivating cutters are fixed to the cutter roller shaft, a plurality of straw stopping transverse strips are arranged on the circumference in the rotary diameter of the rotary cultivating cutters, grooves are formed in the lower portion of the power transmission box body and the lower portion of the supporting arm body with bearing holes supporting the cutter roll shaft serving as centers, the two ends of each straw stopping transverse strip are placed in the grooves, and the straw stopping transverse strips transversely penetrate through the inner side wall of the power transmission box body to the inner side wall of the supporting arm body so that the straw stopping transverse strips can rotate in the grooves along with the cutter roll shaft. In the process of operation, straws are stopped by the straw stopping transverse strips, the phenomenon of twining and hanging of the straws is thoroughly avoided when the rotary cultivator is in operation, and the straw turnover rotary cultivator capable of avoiding straw twining can satisfy the requirement for rotary cultivation of straw turnover.
Description
Technical field
The present invention relates to a kind of agricultural machinery, particularly a kind of grass twisting-free straw returning rotary tiller.
Background technology
China advocates straw-returning energetically in recent years, forbid crop straw burning, because field straw is many, when rotovator rotary tillage process, the phenomenon that stalk weeds are wound around tool roller axis is serious, even cause the rotary blade rotary tillage of can not burying, though the patent No. 200620166370.3 grass twisting-free straw returning rotary tillers have solved the careless phenomenon of twining of tool roller axis, but can find out by the patent No. 200620166370.3 Figure of description, owing to respectively there is a spacing in the medial surface of grass guard and power transmission box and support arm, in these two spacing, can overwork stalk weeds, fail thoroughly to eliminate the stalk lash of power transmission box and support arm inner side, need labor cleaning, affect operation and effect, there is defect.
Summary of the invention
The object of the invention is, for overcoming above-mentioned the deficiencies in the prior art, provides a kind of more perfect grass twisting-free straw returning rotary tiller.
The solution of the present invention is: a kind of grass twisting-free straw returning rotary tiller, comprise the gear-box being fixed on housing, power transmission box body and support arm body, the lower support of power transmission box body and support arm body the two ends of tool roller axis, on tool roller axis, fix several rotary blades, the careless horizontal stripe of several gears is set on the circumference in rotary blade rotating diameter, bottom at power transmission box body and support arm body arranges groove centered by the dead eye that supports tool roller axis, the two ends of the careless horizontal stripe of gear are inserted in groove, keeping off madial wall that careless horizontal stripe traverses power transmission box body to the madial wall of support arm body rotates in groove with tool roller axis.
The madial wall of described power transmission box body and the madial wall of support arm body can be provided with reinforcement and there is no two kinds of forms of reinforcement.
The described bottom at power transmission box body and support arm body arranges groove centered by the dead eye that supports tool roller axis, the actinal surface of groove is equal with the madial wall of support arm body with the madial wall of power transmission box body, and the actinal surface of groove that is provided with reinforcement on madial wall is equal with reinforcement.
The described bottom at power transmission box body and support arm body arranges groove centered by the dead eye that supports tool roller axis, the actinal surface of groove exceeds the madial wall of power transmission box body and the madial wall of support arm body is 1-50mm, and it is 1-50mm that the actinal surface that madial wall is provided with the groove of reinforcement exceeds reinforcement.
Advantage of the present invention is: on power transmission box body and support arm body, groove is set, the actinal surface of groove is equal with the madial wall of the madial wall of power transmission box and support arm, keep off madial wall that careless horizontal stripe traverses power transmission box body to the madial wall of support arm body and rotate in groove with tool roller axis, thoroughly eliminated the stalk lash of power transmission box box inside and support arm body inner side, more adapt to the demand of returning straw into field and rotary cultivation operation, and effect is high, low in energy consumption, energy-conservation, environmental protection, saving of labor, laborsaving.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described with concrete implementation.
Fig. 1 is that one of embodiment of the present invention is the structural representation that the madial wall of power transmission box body and the madial wall of support arm body do not arrange reinforcement.
Fig. 2 is the structural representation that two madial walls for the madial wall of power transmission box body and support arm body of the embodiment of the present invention are provided with reinforcement.
Fig. 3 is the cutaway view of A-A of the power transmission box body of Fig. 2.
Fig. 4 is the cutaway view of B-B of the support arm body of Fig. 2.
