Abstract
The invention, which relates to the technical field of the agricultural machinery, provides a rotary tillage tool capable of being dismounted conveniently. The rotary tillage tool comprises a main shaft and a plurality of tool seats welded to the surface of the main shaft. Inner cavities are arranged in the tool seats; and rotary blades are movably connected inside the inner cavities. Second springs are arranged at the bottoms of the inner cavities; and one end of each second spring is fixedly connected with a flat plate. Blocking teeth are arranged at one sides of the inner cavities and a first spring is arranged at one side of each blocking tooth; and one end of each first spring is fixed to the inner wall of the inner cavity. According to the invention, the rotary blades are inserted into the inner cavities of the tool seats directly and the blocking teeth and protruding teeth are engaged with each other to fix the rotary blades, thereby preventing sliding of the rotary blades. During dismounting, when the rotary blades are pressed with large forces and hands are pulled, the rotary blades can be taken out without any tool for dismounting, so that dismounting becomes convenient. When the rotary blades are repaired, replacement becomes convenient, thereby saving time of the operator and accelerating the working schedule.
Description
Technical field
The present invention relates to technical field of agricultural machinery, particularly a kind of can the rotary tillage cutter of convenient dismounting.
Background technology
Rotovator has a wide range of applications in agricultural plantation, improves agricultural production efficiency, makes people break away from the epoch of manual plantation of ploughing, has also greatly liberated labour.
The main parts of rotovator are rotary blades, and rotary blade is fixed on power transmission shaft, and rotary blade is in the past all adopt to be threadedly connected on power transmission shaft.Rotary blade needs regular maintenance, if do not maintain, is difficult to obtain longer service life, this equally according to higher later stage wear and tear expense, bring economic loss.Face the later stage maintenance will be regular to cutter dismounting, the mode be threaded like this will increase larger workload, needs specific instrument to dismantle, time and effort consuming.Same rotovator in use also can cause the fracture of cutter, so also needs to change cutter timely, and the replacing cutter at substantial time can affect job schedule greatly, affects agricultural planting.The development of problem to rotovator solving cutter dismounting time and effort consuming has huge effect.
Summary of the invention
The technical problem to be solved in the present invention is to provide one can be quick, the rotary tillage cutter of time saving and energy saving dismounting.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of can the rotary tillage cutter of convenient dismounting, comprise main shaft and the some tool rests being welded in described main shaft surface, be provided with inner chamber in described tool rest, be connected with rotary blade in described inner chamber, described intracavity bottom is provided with the second spring, described second spring one end is fixedly connected with flat board, described inner chamber side is provided with obstruct tooth, and described obstruct tooth side is provided with the first spring, and described first spring one end is fixed on interior cavity wall.
As one preferred embodiment, described rotary blade one end facade is provided with double wedge, and described double wedge is snapped at described obstruct tooth.
As another preferred embodiment, described obstruct tooth one end is articulated with on described interior cavity wall, and described obstruct tooth side is provided with the pull bar through described tool rest, and described pull bar one end is provided with handle.
The beneficial effect that the present invention obtains is: the rotary blade in the present invention directly inserts in the inner chamber of tool rest, obstruct tooth and double wedge are engaged fixing rotary blade mutually, ensure that rotary blade can not skid off, firmly press rotary blade during dismounting and pull handle, can rotary blade be taken out, not needing other instruments namely detachable, it is convenient to dismantle, convenient when carrying out maintenance to rotary blade and changing, save operating personnel's time, accelerate job schedule.

Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with embodiment and accompanying drawing, the present invention is further illustrated, and the content that embodiment is mentioned not is limitation of the invention.
As Figure 1-3, a kind of can the rotary tillage cutter of convenient dismounting, comprise main shaft 1 and the some tool rests 2 being welded in described main shaft 1 surface, be provided with inner chamber 5 in described tool rest 2, in described inner chamber 5, be connected with rotary blade 3, bottom described inner chamber 5, be provided with the second spring 10, described second spring 10 one end is fixedly connected with dull and stereotyped 11, described inner chamber 5 side is provided with and intercepts tooth 6, and described obstruct tooth 6 side is provided with the first spring 8, and inner chamber 5 inwall is fixed in described first spring 8 one end.
Further, described rotary blade 3 one end facade is provided with double wedge 4, and described double wedge 4 is snapped at described obstruct tooth 6.Double wedge 4 is engaged obstruct tooth 6 and is pinned by rotary blade 3, prevents rotary blade 3 from skidding off.
Further, described obstruct tooth 6 one end is articulated with on described inner chamber 5 inwall, and described obstruct tooth 6 side is provided with the pull bar 7 through described tool rest 2, and described pull bar 7 one end is provided with handle 9.Obstruct tooth 6 can be made to have certain skew space when dismantling rotary blade 3, making obstruct tooth 6 not hinder rotary blade 3 to move, the setting of handle 9 can make operating personnel lighter when dismantling.
Concrete, during use, rotary blade 3 is inserted inner chamber 5, now the first spring 8 presses down, and the second spring 10 presses down, and rotary blade 3 enters bottom inner chamber 5, first spring 8 recovers, double wedge 4 is engaged with obstruct tooth 6 and pins rotary blade 3, presses down rotary blade 3, the second spring 10 is depressed into lowest part when dismantle, pull handle 9 simultaneously, obstruct tooth 6 is rotated to inner chamber 5 side, does not hinder double wedge 4, now can take off rotary blade 3.
Rotary blade 3 in the present invention directly inserts in the inner chamber 5 of tool rest 2, intercept tooth 6 and the double wedge 4 fixing rotary blade 3 of occlusion mutually, ensure that rotary blade 3 can not skid off, firmly press rotary blade 3 during dismounting and pull handle 9, rotary blade 3 can be taken out, not needing other instruments namely detachable, it is convenient to dismantle, convenient when carrying out maintenance to rotary blade 3 and changing, save operating personnel's time, accelerate job schedule.
Above-described embodiment is the present invention's preferably implementation, and in addition, the present invention can also realize by alternate manner, and under the prerequisite not departing from the technical program design, any apparent replacement is all within protection scope of the present invention.
