Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a soil raising device used for seeding and fertilization.

[Prior Art] Conventionally, this type of soil lifting device has the following features: [1] A powder supply device for seeding or fertilization is arranged on the rear side of the machine body of a down-cut type rotary tiller for covering soil, and In order to cover the sowing or fertilizing position on the rear side of the rotary tilling device, the tilled flying soil is moved slightly laterally to the side directly in front of the sowing or fertilizing position on the rear side of the rotary tillage device. In addition to providing a guide means, a guide means for moving the tilled flying soil toward the sowing or fertilizing position after sowing or fertilizing has been provided (see, for example, Japanese Utility Model Publication No. 19639/1983).

[2] A granular material supply device for seeding or fertilization is placed on the rear side of the Atsupakat type rotary tillage device for covering soil, and the tilled soil that is about to be scattered toward the front side of the machine is placed on the rear side of the machine. A guide plate for inverting and scattering, and a guide means for guiding the tilled flying soil downward on the rear side of the rotary tillage device immediately before the sowing or fertilizing position, and a guide means for guiding the tilled flying soil downward after sowing or fertilizing. , a guide means was provided for guiding the plant to the rear beyond the sowing or fertilizing position (for example, see Japanese Patent Laid-Open No. 120003/1983).

The techniques described in [1] and [2] above were known.

[The problem that the idea attempts to solve]

However, when the rotary tillage device is disposed in front of the seeding or fertilizing position as in the above-mentioned prior art, the following measures are required to cover the sowing or fertilizing position with the tilled flying soil.

That is, in the prior art described in [1] above, the tilled soil is scattered backwards by the down cut, so that the tilled soil is difficult to scatter upward and laterally, and it is difficult to dissipate the tilled soil at the sowing or fertilizing position. Simply placing the rotary tiller in the front position will not work.
Effective soil covering cannot be performed because seeding or fertilization must be carried out in areas where the tilled flying soil has fallen or is falling. For this reason, a wide tilling device is installed to cultivate a wide area, including a position slightly lateral to the front side of the sowing or fertilizing position, and it is installed both in front of and behind the sowing or fertilizing position. It is necessary to provide a guide means to guide the tilled flying soil, and there is a problem that the weight increases due to the enlargement of the tillage device, and the front and rear length becomes longer due to the space for providing both guide means. It was not possible to mound soil to form ridges at the fertilization location.

In addition, in the prior art described in [2] above, since an upper cut type rotary tilling device is used, the uncultivated soil located on the forward side in the direction of movement of the aircraft acts as a wall and pushes the tilled soil upward. , and can be easily guided laterally, but since this device has a seeding or fertilizing device behind the rotary tiller, it is necessary to scatter the lifted soil to the rear. Therefore, there is an increase in the weight of the tilling device similar to the conventional technology in [1] above,
There was a problem that it was not possible to form ridges using a tillage device.

As a means to solve the problems of the prior art described in [1] and [2] above, for example, a sowing or fertilizing device is arranged in front of an upper cut type rotary tilling device, and the soil is covered after sowing or fertilizing. However, simply placing a seeding or fertilizing device in front of the Atsupakatsu rotary tilling device will not allow the covering soil scattered by the Atsupakatsu rotary tilling device to spread over the seeds sown on the ground. The purpose of this invention is to avoid an increase in the weight and length of the tillage equipment, while avoiding an increase in the weight and length of the tillage equipment. To provide a soil raising device which enables furrow formation by a tillage device and which facilitates accurate sowing or fertilization.

[Means to solve the problem]

The technical means of the present invention for achieving the above object is a soil raising device comprising a powder supply device for seeding or fertilizing, and a rotary tillage device for covering soil, as described in [A] to [D] below. It is equipped with the configuration described in .

[B] The discharge pipe of the powder supply device is located forward of the rotary tiller in the machine traveling direction, and is spaced apart from each other in the left-right direction.

[B] The rotary tillage device is disposed between the sowing or fertilization intervals by the discharge pipe, and is of an upper cut type, and scatters the tilled soil on both the left and right sides of the front side in the direction of movement of the aircraft. It is configured to allow

[C] A tilled flying soil guide plate is provided between the front and back of the conduit and the rotary tilling device.

[d] The guide plate has a resistance surface portion formed by bending the outer end portion near the conduit toward the rotary tilling device, and the resistance surface portion allows the tilled flying soil to be horizontally bent. It is configured to provide resistance to outward scattering and to guide the flying soil so that it falls from above and is supplied to the seeding or fertilizing position.

[Effect]

The effects of taking the above technical measures are as follows.

a) Since the rotary tillage device is installed at the rear of the sowing or fertilizing position, it is possible to cover the soil after sowing or fertilizing without any problem without using any means to restrict the covering of soil before sowing or fertilizing.

b The rotary tilling device is of the upper cut type, and the tilled soil for covering soil scattered by this rotary tilling device is formed by uncultivated soil located at the forward side of the tilling position in the direction of movement of the aircraft, forming a wall. It is easy to be guided upward and laterally, and soil can be raised efficiently to both the left and right sides of the tilling device.

c The tilled flying soil that is thrown up by the rotary tillage device and thrown laterally hits the resistance surface of the flying guide plate and is resisted from moving laterally.
It scatters and falls from above in the vicinity of the sowing or fertilizing position with the lateral movement reduced.

[Effect of idea]

B Due to the effect of ab mentioned above, there is an advantage that the tilling device can efficiently form ridges while avoiding an increase in the weight and longitudinal length of the tilling device.

(b) Due to the effect of c. above, the position of sowing or fertilization is less likely to be changed during soil covering, which has the advantage of preventing any hindrance to various post-growth management operations and growth promotion.
