  However, among the front rotary having a structure in which the nail on the outer side of the rotary is reversed, the ones described in Patent Documents 3 and 4 have the tilling claw exposed only by the rotary cover covering the top, Spattering of the soil due to the rotation of the claws can not be prevented with the rotary cover alone, jumping upward from the front to the side and then falling on the crop, damaging the crop, and the crushing situation of the soil is poor and stirring There were unforeseen issues, such as a large soil mass that was insufficient and could not be crushed and scattered on the crop.

  Therefore, the present invention aims to improve these conventional problems, prevent the soil from being scattered as a lump, and finely pulverize the soil after tillage to increase the agitation and improve the finish. Is.

  The present invention has an engine mounted and a transmission case and a tilling device integrally formed toward the front, and a tilling claw shaft so that the outermost tilling claw rotates in reverse to the forward rotation of the traveling wheel, In the front rotary tiller configured with tilling claws, it is characterized in that a soil cover is provided at the front end of the rotary cover attached to the front of the machine body from the front to the left and right sides to prevent soiling and scattering. This is a front rotary structure.

  According to the present invention, due to the size and shape covered by the rotary cover, an insufficiently crushed soil mass that greatly affects the quality of the crop is prevented from scattering from the front to the side toward the crop etc. Providing anti-soil-scattering rubber spills on the left and right sides from the front of the plant can prevent the soil from scattering into the crop, so that it can produce crops that are not deformed by scratches or fallen objects, and it has been shattered by scattering until now. Insufficient soil mass is blocked by the rubber splatter that prevents splashing of the soil, bounces back into the rotary and is reliably crushed, improves the agitation of the soil, improves the finish, and the rubber slick gently pushes the crops. Damage to crops in contact with the rotary can be minimized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an overall side view of a front rotary cultivator. 1 is an airframe of a front rotary cultivator, and an engine 2 is provided at the upper center of the airframe 1, and the power of the engine 2 is It is transmitted to the mission case 3 and transmitted to the traveling wheels 4 on the left and right, and transmitted to the tilling claw shafts 7 on the left and right of the rotary drive transmission case 5 integrally formed forward from the mission case 3. A plurality of tilling claws 8 constituting the front rotary 6 are attached to the tilling shaft 7, and a soil cover 10 is attached to the rotary cover 9 to perform tilling work in a field or the like. It is configured as follows.

  In the present invention, when the driving force generated by the engine 2 is transmitted from the transmission case 3 to the driving wheel 4 and used as the vehicle driving force, the transmission case 5 and the rotary claw shaft 7, It becomes effective when transmitted to the tilling claw 8.

  In the present invention, a front rotary 6 equipped with a tilling claw shaft n 7b configured such that the left and right outermost tilling claws n 8b of the front rotary rotates in a reverse direction with respect to the forward rotation direction of the traveling wheel 4. In this case, when the tilling claw 8 performs the tilling work while raising the soil 14 forward and sideward, the soil splashing preventing rubber scrap 10 is provided to prevent the soil 12 from scattering, It is the structure which crushes the earth lump 12 finely at the time of tillage.

  First, the front rotary 6 to which the present invention is attached will be described with reference to FIG. 2 front view during front rotary tillage and FIG. 3 side view during front rotary tillage. A tilling claw shaft m 7a having a rotation direction axis on the rotary drive transmission case 5 side, and a tilling having a rotation axis that is coaxial with the tilling claw shaft m 7a and rotating in the reverse direction. It is set as the structure which arrange | positions the nail | claw axis | shaft n7b.

  The tilling claw 8 of the front rotary 6 is composed of a tilling claw m8a that rotates forward to the rotary drive transmission case 5 side and a tilling claw n8b that reverses outward, and splashes forward due to the forward rotation of the tilling claw m8a. There are few, and most of the soil 14 is discharged in the direction of the rear mission case 3.

  In the front rotary tilling work diagram of FIG. 5, the tilling claws n 8 b of the reversing tilling axis n 7 b jump the soil mass 12 from the front to the side and perform the tilling work while being scattered.

  In the present invention, since the rotary cover 9 of the front rotary 6 that implements the device only covers the upper side as shown in FIG. 3, the plurality of tilling claws 8a and 8b cannot be covered, and FIG. As shown in FIG. 2, the soil splattering prevention rubber scrap 10 is attached from the front of the rotary cover 9 to the left and right sides.

  FIG. 4 is an exploded view of the soil scatter prevention rubber slag 10 as viewed obliquely from the front. The soil splattering prevention rubber scrap 10 provided at the left and right side positions from the front of the front rotary 6 is made of an elastic material such as rubber, and is held so as to be in close contact with the rotary cover 9 by a pressing iron plate 11, such as bolts and screws. It is fixed with.

  As shown in FIG. 5, the soil splattering prevention rubber sag 10 is obtained by repelling the lump 12 raised by the reversing tillage n8b as shown in FIG. 5 on the tilling nail n8b as shown in FIG. To change the soil 14 with fine stirring.

  The holding iron plate 11 is configured so as to maintain the shape of the rotary cover 9 along the curved surface at the front end, and to maintain the strength of the rotary cover 9 while maintaining the bending of the anti-scattering rubber scrap 10. 10 is prevented from being easily damaged by the scattered lump 12.

  The present invention has the above-described configuration and structure, and is effective when the tilling claw 8 of the front rotary 6 is rotated to perform the tilling work.

  The soil 14 cultivated by the front rotary 6 equipped with the soil splash prevention rubber scrap 10 can produce a crop 13 that is not deformed by scratches or fallen objects, and has not been sufficiently crushed by scattering until now. The crushed lump 12 bounces back into the front rotary 6 and is reliably crushed, increasing the agitation of the soil 14, and the soil spill prevention rubber scrap 10 gently pushes the crop 13, thereby minimizing the damage of the crop 13 that comes into contact with it. As a result, there is an effect of improving the production of excellent crops and maintaining the fertilizer effect of the soil 14 well.
