Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an earthing apparatus for mulching that can mulch a plurality of ridges with a single wide film or sheet.

[0002]

[Technical background]

 In general, mulching is a method of covering each row with a single film or sheet, but there is a tendency to improve the efficiency of work with a single film or sheet for a plurality of rows with a motive machine.

When the wide coating is mulched, a lift is generated in the wide coating as the wind and the internal temperature rise, and in order to prevent this, a weight means is provided even at an intermediate position in the width. Since the lifting force must be suppressed by the action of the weight, it is in the direction of mechanically performing this at the same time as the marching work.

[0004]

[Prior art]

 When mulching the wide cover described above, it is obvious that both ends are at the middle position in the width and the field soil can be applied to the rows to apply the weight effect at the same time as the mulching work. There is a technology disclosed in Japanese Patent No. 220496.

[0005]

[Problems to be solved by the device]

 The disclosed technology scoops up the soil in the field by the action of the mulching device, conveys it by a conveyor to the rear of the device, and drops it from the upper part of the already stretched covering to a row by the device. It is expected to have an ideal effect on the desk, which is to be placed underneath.

However, as a practical matter, the soil in the field to be worked has a wide variety of soil types, and there is also a soil with a high degree of wetness and a high viscosity, and conversely, a dry clod soil or a dry soil soil. There are also fine powders.

In the case of the former high-humidity and high-viscosity soil, it may be stuck between the conveyor and the frame to stop the operation of the equipment.

[0008] The latter has a high degree of dryness, and the granular soil overflows at the time of scooping, the transport amount becomes imbalanced, and it serves as a weight from the time it is dropped on the covering body. In some cases, if the soil is placed in such a state, the soil line will not be scattered due to the wind.

In order to overcome all the above-mentioned bad cases, the present inventor has investigated these defects, and conceived that the earth-mounting form to be applied on the covering body should be changed from row-row earth-mounting to massive earth-mounting. Therefore, it is suitable for all soils mentioned above, does not hinder even high-viscosity soils, and the soil flow that flows continuously even for dry soils is collected by a set amount by a plate. Scattering can be prevented by making a nodule and applying it to the soil.

On the other hand, even for crops, there is no air-blocking phenomenon for adjacent ridges due to row-rowed soil, air can flow freely between each ridge, and temperature changes due to morning and evening irradiation angles, shade, etc. At times, these are averaged so that the difference between superiority and inferiority due to topography can be reduced.

[0011]

[Means for Solving the Problems]

 As a means for achieving the above-mentioned object, this invention is a device capable of mulching a plurality of ridges with a single wide film or sheet, and before and after a transport gutter with a U-shaped cross section having a digging bar at the tip. The front support frame and the rear support frame support the drive shaft with the drive sprocket fixed to them, and the driven shaft with the driven sprocket attached to them, so that the support frame can be pulled by the tractor. It is attached to a main frame equipped with connecting means, and an endless chain is laid on each sprocket so that the forward path is on the transfer gutter and in a parallel position, and is set outside the chain as appropriate. A plate with a shape that conforms to the inner groove shape of the transport gutter is attached through the equal gap so that the outer periphery of the plate can travel closer to the inner surface of the transport gutter. The shaft by fixing the ground wheel, is characterized in that the driven rotating action of traveling of which device was made to rotation drive source of the chain.

[0012]

[Action]

 A wide film is stretched to a set position by means of the equipped means when the device is run by being pulled by the tractor, and even in the earth mounting device of the present invention, this is driven by the rotation of the ground wheel. As a result, the chain rotates, and the plate runs in the transport gutter, pointing toward the rear of the device.

On the other hand, as the device travels, the soil in the field is scooped up by the action of the digging pit at the tip of the transport gutter, and this state is continued without interruption, so that the pushing and compressing action to the rear is received. Be transferred.

[0014] This is because the soil scraped only by the forward action of the transport gutter is forcibly transferred backward in the transport gutter by the plate rotating from the front direction.

During the transfer by the plate, the transferred soil is formed into one nodule and dropped from the rear end of the transport gutter onto the wide film already stretched by the tensioning mechanism.

As described above, the nodule soil dropped from the transport gutter is linearly installed on the wide film at a distance corresponding to the installation gap of each plate attached to the endless chain. Is.

[Effect of device]

 The present invention is configured as described above, and at the same time when mulching a wide film, at the same time, the embankment action of the film retainer provided at the intermediate width position is set in the transport gutter that advances together with the mulching device. The soil is scraped by the advancing action, and it is forcibly transported to the rear of the transport gutter by the rotation of the plate provided intermittently, so that the soil to be transported is completely irrespective of its soil characteristics. It can be dropped on the film under the same conditions.

Since the transporting means is a plate, the soil that has been scraped is gathered in a certain amount and is placed in a line on the stretched film in a line.

The multiple ridges mulched by the film can freely move in and out of parallel ridges due to the scattered soil groups, so the temperature difference between local cooling and heating can be eliminated, and an averaged atmosphere for crops can be obtained. There is an effect that can be managed naturally.
