Abstract

PURPOSE:To fill soil into a groove formed on the top of a ridge with a transmission case by lowly covering the front of the front half part of a tilling tine with the front half part of a cover above a tilling part and highly covering the back of the rear half part of the tilling tine with the rear half part of the cover. CONSTITUTION:The front part of the upper front half part of each tilling tine 3 is lowly covered with the front half part C1 of a cover. Soil collected to the center from the right and left sides is guided with the cover and discharged backward. The rear part of the upper rear half part of each tilling tine 3 is highly covered with the rear half part C2 of the cover. Highly splashed soil is allowed to forcibly drop from the reverse face of the rear part C2 of the cover to fill the groove formed by a transmission case 2 with the soil.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is an improvement on a device that uses rotating tilling claws to heave soil from the left and right toward the center to create ridges.

(Prior Art) Conventionally, this type of ridge-raising device has a mission case 2 attached to the center of a tilling shaft l that rotates orthogonally to the direction of movement of the machine.
The symmetrical tilling claws 3 attached radially to the tilling shaft 1 are used to heave up the "2" toward the center, and then the left and right arc-shaped molding plates 4 provided behind the tilling shaft 1 are used to raise the "2" toward the center. Adjust the form.

However, the upper half of the tiller is raised in the center from the left and right by the tiller and looks in the direction of movement of the tiller. It stagnates in one direction, blocking the aircraft's progress and expending power.

Therefore, conventionally, as shown in Fig. 4, the upper blade of the tilling part is covered with a substantially horizontal covering plate A, and the mound that is thrown off by the tilling claw is reflected onto the lower surface of the covering plate A, and this is transferred to the machine body. There is a part that is moved to the rear of the tilling claws 3 as it progresses, and lowers the height of the top that should be raised at the center shown by the chain line in FIG.

(The invention attempts to solve it! 1B> However, even with this method, the lower part of the transmission case 2 comes into contact with the raised part in the center of the tilling shaft 1, and the semi-cylindrical shape raised by the rear left and right molded plates 4 There is an unavoidable drawback that a kerf is formed at the center of the top of the ridge, which hinders the growth of crops planted on the ridge.

The present invention is to transport the soil moving toward the center from the left and right sides of the tilling shaft 1 backward so that it does not stagnate in front of the front half of the tilling claws 3, and to leave a cut groove formed by the mission case 2 on the middle surface of the top of the ridge. This is to ensure that there are no problems.

(Step F to solve the problem) A transmission case 2 is attached to the center of the tilling shaft 1, and a cover is placed above the tilling part where the tilling claws 3, which are attached radially to the tilling shaft 1 and have one order of magnitude, direct the crabs from the left and right toward the center. The front half C1 of the cover C covers the front half of each tilling claw 3 low, and the rear half C2 of the cover C covers the rear half of each tilling claw 3 high.

(Function) The pilot grasps the handles I (attached to the left and right sides of the aircraft) and moves backward while rotating the drive wheels W attached to the aircraft in the direction of the arrow in FIG. 1.

The tilling claws 3 attached radially to the tilling shaft L are the wheels W.
Rotate in the opposite direction to move the - from the left and right to the center.

The upper part placed in the center should originally be raised in front of each tilling claw 3 as shown by the chain line in Figure 3, but should be the front half of the cover that covers the front of the tilling claw 3 low. Part C1 (
7) It is blocked by the back surface and moves quickly backwards by the tilling claws that rotate as the aircraft advances.

However, the rear part of the rear half of each tilling claw 3 is T part C behind the cover.
2, the soil sent from the front by the tilling claws 3 is well splashed, reflected to the rear part C2, and falls with force, filling the groove formed by the contact with the mission case 2. .

(Embodiment) As for the embodiment shown in the drawings, ``J+'' indicates a tilling shaft perpendicular to the traveling direction of the machine body, and is a center drive type tilling shaft rotated by a mission case 2 attached to the center thereof.

3 is a tilling claw that is attached radially and symmetrically to the tilling axis 1,
Spread the dug up soil from left to right to the center.

A cover 〇 is placed on the I- side of the tilling part consisting of the tilling shaft L and each tilling claw 3. The front half C1 of the cover covers the front half of each tilling claw 3 low, and the rear half C2 covers the front half of each tilling claw 3. The rear part of the rear half of the tilling claws 3 is highly covered.

Arc-shaped molded plates 4 are fixed to the rear left and right sides of the cover C, and the raised lid that appears from the cover C as the aircraft advances is shaped into a semicircular shape.

H is a pair of handles attached to the left and right sides of the aircraft, W is a driving wheel, and the engine mounted on the aircraft is omitted.

The front half C1 of the guide bar 0 is preferably formed into an arc shape as shown in FIG.

(Effects of the Invention) According to the present invention, the front half of the upper half of each tilling claw 3 is covered low by the front half C1 of the cover, so the soil that has been brought to the center from the left and right is guided by the cover and flows backward. Since it does not stop in front of the tiller and impede the aircraft's progress, the aircraft moves forward with light power.

Also, the soil that has flowed out behind the tilling claws 3 is in the rear part C2 of the cover.
Since the soil is covered high, the soil is splashed high by the tiller.
It collides with the back surface of the rear half part C2 of the basket cover and falls down with force, filling the groove formed by the contact with the lower part of the misho case 2, which not only does not hinder the growth of the crops to be planted, but also makes the ridges higher. , this effect is produced.
