Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the rotary cultivator convenient for cutting soil and breaking soil comprises a body 1, and a box body 2 with a downward opening is arranged behind the body 1. The horizontal rotation is connected with axis of rotation 3 between the both ends lower extreme lateral wall of box 2, and the interval is provided with a plurality of rolling discs 4 between 3 surfaces of axis of rotation, and 4 fixed connection of rolling discs in axis of rotation 3 to the outer wall equipartition has rotary blade 5 all around for rolling disc 4.

As shown in fig. 2 and 3, one end of the rotary blade 5 away from the rotary disk 4 is bent to form a bent blade 51, and one end of the rotary blade 5 away from the bent blade 51 is connected to the side wall of the rotary disk 4 by a bolt.

When the rotary cultivator is used for rotary tillage of the soil, the lower end face of the box body 2 is close to the soil, the rotary cultivator is started, the rotary shaft 3 drives the rotary blades 5 on the peripheral outer wall of the rotary disc 4 to rotate, and the rotary blades 5 turn up and rub the soil to realize soil crushing. At this time, the rotational force of the rotary shaft 3 is derived from the resistance caused by the contact of the rotary blades 5 with the soil.

Further, the present application may also provide another embodiment, wherein a driving motor (not shown) is disposed at one side of the box 2 and can drive the rotating shaft 3 to rotate.

Further, since the number of the rotary blades 5 is preferably four, the number of the blades 51 is also four. The bending directions of the two bending knives 51 are the directions close to the machine body 1, and the bending directions of the other two bending knives 51 are the directions far away from the machine body 1. By additionally arranging the bent blades 51 with different directions, the contact area between the rotary tillage blades 5 and soil is effectively increased, so that the rotary tillage area of the rotary cultivator is increased, and the working efficiency is improved. Meanwhile, the method has the advantage of more uniform soil crushing.

Because the one end that rotary blade 5 deviates from curved knife 51 can be dismantled and connect in the lateral wall of rolling disc 4, consequently when needs are changed or are maintained single rotary blade 5, only need dismantle rotary blade 5 and rolling disc 4's connecting bolt to install new rotary blade 5 and can realize changing the function of rotary blade 5 alone, effectively improve the speed of changing rotary blade 5, strengthen the maintenance convenience simultaneously, further promote the practicality.

As shown in fig. 2 and 3, a paddle wheel 6 which is perpendicular to the rotating direction of the rotating discs 4 is vertically arranged between two adjacent rotating discs 4, one end of the paddle wheel 6 is rotatably connected to the side wall of the lower end of one side of the box body 2, which is far away from the machine body 1, the other end of the paddle wheel is close to the rotating discs 4, and a plurality of broken pieces 41 are uniformly distributed on the side wall of the rotating discs 4.

Through vertically being provided with between rolling disc 4 with rolling disc 4 rotation direction mutually perpendicular's thick liquid wheel 6, when using above-mentioned rotary cultivator rotary tillage soil, rotary blade 5 turns up soil earlier and rubs, and thick liquid wheel 6 turns up again and the breakage with the soil that has rubbed this moment, realizes hacking many times, has the advantage of abundant hack. It should be noted that the rotation power of the paddle wheel 6 comes from the rotary blade 5 to turn up and grind the soil, the turned-up soil falls on the blade of the paddle wheel 6, and the paddle wheel 6 is forced to rotate. And the rotating paddle wheel 6 can carry out secondary crushing on the turned soil under the action of the rotating inertia.

Through set up a plurality of broken pieces 41 at the rolling disc 4 lateral wall, the thick liquid wheel 6 is turned up soil, and soil strikes the broken piece 41 of rolling disc 4 lateral wall under the effect of centrifugal force, smashes remaining clod in the soil, and the clod is smashed the back, falls on rotatory thick liquid wheel 6, smashes soil once more, has the advantage of many times hacking.

As shown in fig. 2, a plurality of blades 7 are provided at intervals on the outer wall of the casing 2 on the side close to the machine body 1, and the blades 7 are inclined downward and have lower ends lower than the lower end surface of the casing 2. The outer wall of the box body 2 departing from one side of the machine body 1 is hinged with a smoothing plate 8, and the lower end of the smoothing plate 8 is lower than the lower end face of the box body 2.

Through 2 outer walls intervals at the box that are close to organism 1 one side be provided with a plurality of break shovel 7, when using above-mentioned rotary cultivator rotary tillage soil, break shovel 7 earlier with soil turn-up and breakage, then rotary blade 5 and thick liquid wheel 6 are abundant breakage with soil again, and break shovel 7 can effectively reduce the work load of rotary blade 5 and thick liquid wheel 6 to have the more abundant advantage of hack.

Through having the board 8 of pacifying in deviating from 1 one side of organism 2 outer walls of box, after rotary blade 5 and thick liquid wheel 6 fully broken with soil, pacify board 8 and strickle soil, have the advantage of leveling soil, the follow-up operations such as cultivateing of being convenient for further promotes the practicality of rotary cultivator.

The specific embodiments are only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiments without inventive contribution as required after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
