Description

[Detailed Description of the Invention] Technical Field of the Invention This invention relates to a soil-entering device for a power tiller that applies soil to the roots of crops grown on ridges.

Technical background of the invention and its problems Conventionally, for crops such as tobacco, the ridges are covered with vinyl or the like, holes are formed in the vinyl, and seedlings are transplanted onto the upper part of the ridges. Then, when the seedlings have grown to a certain size, soil is poured into the base of the plants to prevent weeds from growing and to prevent the ridges from drying out. Methods for this soil filling include manual work using a hoe and mechanical work using a tiller. Manual work is extremely inefficient and causes worker fatigue. Mechanical work using a tiller improves work efficiency and reduces worker fatigue, but leaves may be damaged or buried in the soil, reducing yields.

Purpose of the invention This invention was devised in view of the above points, and the purpose is to obtain a soil-entering device for a tiller that can improve work efficiency and prevent damage to leaves and burying of leaves in the soil. shall be.

Summary of the device This device is equipped with tilling shafts that rotate with left and right axes in front of the machine body of the tiller that runs between furrows in the direction of travel. A claw is fixedly provided, and a pair of left and right guide covers are provided that cover the top of the tilling shaft and the flip-up claw and have outer ends extending outward from the tilling shaft, and these guide covers are connected to the outer end of the tilling shaft. is rotatable within a predetermined range so as to move up and down, and the guide cover is provided with a guide roller that contacts the ridge shoulder surface and rotates as the aircraft advances, and the guide cover is provided with an upper part of the guide roller. A lifting cover part is provided that extends forward in a covering state and has a distal end edge close to the shoulder surface of the ridge. As a result, during soil digging work, the guide roller contacts the ridge shoulder surface and rotates as the machine advances, and the guide cover rotates up and down according to the unevenness of the ridge shoulder surface, so that the tip edge of the lifting cover part is always Keep the leaves close to the ridge shoulder surface, use this lifting cover to lift the leaves close to the ridge shoulder surface, and while lifting the leaves, put soil at the base of the plant and damage the leaves or remove soil. This structure is designed to prevent the work from being buried in the work area, and to improve work efficiency.

Embodiment of the invention An embodiment of the invention will be described based on the drawings. Although only a portion is shown, a frame 3 is connected to the front of the body 1 of the power tiller in the direction of travel through a hitch 2. A chain case 4 is held vertically approximately at the center of the frame 3.
A pair of left and right tilling shafts 5 having left and right axes are provided at the lower part of the tiller. A plurality of flip-up claws 6 are fixed to the tilling shaft 5 for flipping up soil outward.

Extension plates 7 extending in the left and right directions are fixed to the left and right sides of the frame 3, and a guide cover 9 is connected to the left and right ends of these extension plates 7 by hinges 8 so as to be rotatable in the vertical direction. There is. The frame 3 also has a center metal fitting 10 extending upward.
is fixed. A hanging fitting 11 is provided, one end of which is rotatably connected to the guide cover 9, and an elongated hole 12 is formed in the other end of the hanging fitting 11, and the elongated hole 12 is inserted through the elongated hole 12. A bolt 13 is attached to the center metal fitting 10.

The guide cover 9 covers above the tilling shaft 5 and flip-up claws 6, and has a width dimension extending further outward from the tilling shaft 5, and has a front end and a rear end bent downward. There is. Front bend 1
A guide roller 15 having a left-right axis is rotatably held on the front surface of the roller 4. Further, a lifting cover part 16 is fixed to the front end of the guide cover 9 and extends forward while covering the upper part of the guide roller 15. It is located slightly above.

A grounding wheel arm 18 extending in the vertical direction is attached to the tip of the frame 3 so as to be movable in the vertical direction and fixable at any position by tightening bolts 19. 20 is attached. Furthermore, the front guide 2 is attached to the ground wheel arm 18 by a bolt 21.
2 is attached so that it can be moved vertically and fixed at any position. Furthermore, a front cover 23 is fixed to the front end of the extension plate 7 together with the front guide 22 to prevent soil from scattering forward.

In such a configuration, first the tail wheel arm 18
is moved up and down, and the tail wheel 20 is flipped up and fixed with bolts 19 at a position where the pawl 6 is at an appropriate depth. Next, move the front guide 22 up and down,
It is fixed with bolts 21 at a position where the lower end does not catch on the ground. Then, the bolts 13 are loosened, and the guide cover 9 and guide roller 15 are made rotatable about the hinge 8.

Here, the machine body 1 is positioned between the furrows and the guide rollers 15 are brought into contact with the shoulder surfaces of the furrows, and the machine body 1 is moved forward. At this time, the flip-up claws 6, which are rotated by driving force from an engine (not shown), flip up the soil outward. As the machine body 1 advances, the guide roller 15 rotates while coming into contact with the ridge shoulder surface, and when the ridge shoulder surface is uneven, it rotates vertically together with the guide cover 9 around the hinge 8, and the ridge shoulder surface is rotated. The state of contact with the shoulder surface is maintained. Therefore, the tip edge 17 of the lifting cover part 16 is always maintained in a state close to the ridge shoulder surface, and the lifting cover part 16 touches the ridge shoulder surface or lifts up a leaf that is close to the ridge shoulder surface. In this way, soil is poured into the base of the plant while the leaves are being lifted by the lifting cover part 16 and the guide cover 9 continuous thereto, so that there is no possibility that the leaves may be damaged or buried in the soil. is prevented. In addition, since the guide cover 9 is freely rotatable in the vertical direction, even if the height of the ridge or the slope of the ridge shoulder surface is different, it is possible to prevent the leaves from being damaged or buried in the soil without making any special adjustments. You can put soil back into the original location.

Note that the thrown up soil is guided by the guide cover 9, and a certain amount of soil is poured into a predetermined plant base.

Effects of the device Since this device is configured as described above, soil can be placed at the base of crop plants without damaging the leaves or burying them in the soil. Even if the slope of the surface is different, soil filling work can be carried out without making special adjustments accordingly.Furthermore, it is only necessary to move the machine by bringing the guide roller into contact with the ridge shoulder surface, which improves work efficiency. It has the effect of being able to improve performance and reduce labor.
