Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to improvements in cultivators.

Conventional technology and problems 1 There is a leaf protector for seedlings, both ridge type and multi-row type, which is equipped with a disc. However, it is equipped with a soil collecting tool that cuts the ridges up to the vicinity of the crop row and collects soil in the ridges. The structure does not exist (for example, Hidenobu Shoji, April 20, 1964, issued by Yokendo Co., Ltd. 11th edition, Introduction to Agricultural Mechanics, pages 218 to 225.
(See page 9, Chapter 3, Section 3 cultivators).

So when you work from the beginning with a cultivator,
The leaves can overwhelm the crop rows and cause root rot. In order to prevent this root rot, first, the ridges are manually broken down to the nearest row to remove the soil into the ridges, the grass is removed, and then the soil removed to the ridges is cultivated with a cultivator. I'm moving to the side. Therefore, they are forced to perform inefficient agricultural work.

The present invention has been made paying attention to such a problem, and the agricultural work in which the ridges are cut to the nearest row of the crops to collect the soil in the ridges, and then the soil collected in the ridges is brought to the crop row side to some extent. The purpose of the present invention is to provide a cultivator which can be mechanically and efficiently performed, and to raise the soil temperature and promote the growth of crops by such agricultural work.

Means for Solving the Problems The means adopted by the present invention to achieve the above-mentioned object is to collect the soil near the crop row into the ridges at the front end of the mounting handle hung on the main rod. A soil plate is provided, and to the rear of the soil collecting plate on the side of the intermediate portion of the main girder projecting rearward on the mounting handle,
This means that a side blade was provided to bring the soil collected by the soil collecting plate toward the crop row to some extent.

Action If the main rod is advanced toward the front end of the mounting handle, the soil collecting plate will break the ridges to the nearest row of crops and collect soil between the ridges. Then, the side blades arranged behind the soil collecting plate bring the soil collected in the ridges by the soil collecting plate toward the crop row to some extent. Therefore, the ridges are turned upside down to the nearest row of crops.

Example A case of a traction type or riding type multi-joch cultivator (for four ridges) by a tractor or the like will be described with reference to the drawings.

The main rod (1) is equipped with a coupler (not shown) in the case of a towed type so as to be connectable to a tractor, and is equipped with an engine, a cockpit, a control device (not shown) in the case of a riding type. It is self-propelled. The main rod (1) of the illustrated example shows the case of four ridges, and the mounting handles (2) of one number larger than the number of ridges are vertically arranged. The mounting handle (2) is formed in a ∠ shape whose basic shape is a side L-shape, and the upper end is attached to the main rod (1) so that it can be removed with a clamp, bolt, nut, etc. and the mounting position can be changed. In the mounting handle (2), the main girder (4) is attached to the bent portion with bolts and nuts, the main girder is projected rearward, and the earth collecting plate (3) is attached to the front end (the end in the forward direction). ) Is installed. The soil collecting plate (3) cuts the ridges close to the crop row (a), collects soil in the ridges, and weeds, and cooperates with the side blades (5) to raise the soil temperature and grow the crops. It is a member to improve. The earth plate (3) is
It is shaped like a dish (a circular dish in the example shown), and is attached to the first horizontal shaft (6) arranged at the front end of the mounting handle so as to be rotatable in the up-down direction by means of a rotating tube (7), and there is a solid obstacle. When an object is encountered, it is configured so that it can be swung upwards to get over it. The earth collecting plate (3) is rotatable in the front-rear direction on a bearing (9) mounted on a rotating rod (8) projecting downward from the rotating pipe (7) so that the mounting height position and the mounting angle can be adjusted freely. The bearing (9) is constructed so that the soil can be cut down while rotating in one direction as it advances.
The cutting depth to the soil is adjusted by adjusting the mounting height position of the, and the angle with respect to the traveling direction is adjusted by adjusting the mounting angle of the bearing (9). The width of the ridges is adjusted according to the condition of equal growth. Collection board (3)
Is a member for breaking up the ridges to the vicinity of the crop row (a), collecting soil in the ridges, and turning upside down. Therefore, when viewed from the front, the front side (forward direction side) and the lower side are spread. It is provided on the rotating rod (8) so that the ridges can be cut down to the vicinity of the crop row (a), and the soil that has been cut down can be collected in the ridges in combination with the dish-shaped cross-section of itself. . The earth collecting plate (3) has a first
A tension spring (11) is stretched around the horizontal shaft (6) and a second horizontal shaft (10) arranged at the front end of the mounting handle (2) side by side with the horizontal shaft (6) near the bearing mounting portion of the rotating rod (8). The earth collecting plate (3) is always urged downward about the first horizontal axis (6) so that the soil can be immediately cut when overcoming an obstacle. The tension spring (11) is attached to the first horizontal axis (6) and the second horizontal axis (10) in the forward direction (forward direction) and attached to the spring hook (12) on the horizontal axis side end (upper end in the figure). And urge the earth collecting plate (3) downwards at all times.

The main rod (4) projects rearward from the mounting handle (2),
Side girders (13) are laterally projected from the longitudinal middle part, and side blades (5) are hung vertically at the part where the side girders are behind the soil collecting plate (3), and Central blade (1
4) is installed vertically so that the soil collected by the soil collecting plate (3) between the ridges can be moved to the crop row (a) to some extent by the side blades (5), and the soil between the ridges can be centered. Allow some plowing with the blade (14). The side blade (5) is a member that cooperates with the soil collecting plate (3) to bring the soil collected between the ridges by the soil collecting plate (3) to a certain extent to the crop row (a) and turn it upside down. It is a member for raising soil temperature and improving crop growth. The side blade (5) may have a shape known per se, and the mounting means may be a known mounting means such as a detachable type or a movable type, but the number of the side blades (5) arranged behind the soil collecting plate (3) is not limited. Due to the arrangement, the number is the same as that of the earth collecting plate (3).

Next, the experimental results using the cultivator of the present invention will be explained.In the case of potato, it is possible to dispense with herbicide, in the case of beet it is possible to dispense with root preservative, in the case of beans,
Finally, the soil was removed and the growth was good.

Effect of the Invention Since the present invention is configured as described above, if the main rod is advanced toward the front end of the mounting handle, the soil slab breaks down the ridges to the nearest row of crops and collects soil between the ridges. . Then, the side blades arranged at the rear of the soil collecting plate bring the soil collected by the soil collecting plate into the ridges to a certain extent. Therefore, the ridges are turned upside down to the immediate vicinity of the crop, the soil temperature is raised, and the growth of the crop is promoted. Further, there is an advantage that one machine can efficiently perform agricultural work.
