JPH0484833A - Whole face-coated mulcher applied by rolling both end of film inside soil - Google Patents

Abstract

PURPOSE:To obtain a whole face-covering mulcher capable of enhancing sterilizing effect of soil and preventing scattering of poisonous gas and weatherproofing by wholly covering a film while rolling both ends of fed film inside. CONSTITUTION:Film is lightly pressed with it's weight without strongly pressing the film covered on a groove by a film reversing lever 4 fixed to a supporting lever 14. Then the soil is moved using a soil moving plate 5 inside the film reversing lever 4 while pulling out the film with a film reversing assistant lever 6 and the film is rolled in on upper side of the film reversing lever 4 and reversed. The soil moving amount is controlled with a soil cutting blade 7 fixed in the lower part of soil moving plate 5. A soil feed screw conveyer 10 is attached in the rear part of soil moving plate in order to improve soil- moving performance. Thereby stabilized film covering is made possible regardless of soil conditions such as drying of soil or much moisture.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mulcher that covers the entire surface with a film for the purpose of preventing the scattering of toxic gases, improving the disinfection effect, and providing a film coating that is difficult to peel off even in wind and rain.

[Conventional technology]

As shown in Figure 5, in the conventional mulcher, after soil disinfection, the side edges of the film are covered with soil by ±33°, so the covered soil has no disinfecting effect, and the distance between the covered films is 20 to 30°.
This creates a gap of n, which not only reduces the disinfection effect in that area, but also
Toxic gas scatters and causes pollution. In addition, the covered film has serious problems in agricultural work, as the soil covered on the side edges of the film is washed away by wind and rain, and the film is easily peeled off.

[Problem to be solved by the invention]

In conventional mulchers, the covered film 34 is easily peeled off by wind and rain as described above, and gaps are created between the covered films, so the films, which have poor soil disinfection effects, are stuck together, making it possible to cover the entire surface with the film. The aim is to provide a fully covered mulch that is resistant to wind and rain while increasing the soil disinfection effect and preventing the scattering of toxic gases.

[Means to solve the problem]

In order to achieve the above object, when both ends of the film of the present invention are rolled inside the soil to cover it, the amount of soil to be rolled in is ensured, and at the same time, the tread pressure of the film at the time of covering is improved, and the film is spread from side to side. To eliminate misalignment, create grooves at the bottom of both ends of the film. The groove star has a shape where the soil is pushed to one side,
The soil that has been made is raised to the inside of the mulcher to secure the amount of soil that can be wrapped in the film, and the tip 28 of the groove pear is designed to prevent the side surface of the groove star 1 from coming into contact with the existing film 32 during the back-and-forth work of covering the film. It is effective to curve the tip of the pear inward to prevent the film from catching and tearing.

This can be done by pressing down the film coated on the grooves that have been made, but it is also better to add a film reversal assisting rod 6 and a cutting front blade 7. Under adverse conditions such as dry soil or overhumidity,
In order to improve the reversal winding of the film, it is preferable to install a soil feeding screw conveyor 10.

[Function] The full-coverage mulcher configured as described above, which wraps both ends of the film inside the soil to cover the soil, uses a small portion of the roll-shaped film 18 supported by the holder 17 to make it easier to roll both ends of the film into the soil. When making grooves on flat ground, the groove pears 1 installed on the lower front are designed to prevent the soil raised inward from collapsing into the grooves that have been made. It has been extended. Immediately after making grooves with groove making star 1, film 18 is fed out and the grooves on the side edges of the film spread over the ridges are pressed down with tread pressure width 2. The large tread pressure width 2 is configured to be freely transferable, and is constantly pressed down by the ring 15 provided on the large tread width support rod 13 to hold down the film on the groove, and is further transferred to the small tread width support rod J2j. The provided spring 16 presses the film 31 while constantly moving the small tread pressure width 3 downward (see FIG. 4). Since the film is pressed by these two pressing wheels 2.3, the film 31 is prevented from shifting from side to side.

And the film reversing rod 4 fixed to the treadle wheel small support rod 14
The film covered on the groove is not pressed too hard, but is held down lightly by its own weight. Next, while pulling it out with the film reversing auxiliary rod 6, the soil is moved with the soil moving plate 5 inside the film reversing rod 4, and the soil is moved by the film reversing rod 4. Roll the film onto the upper side of 4 and turn it over.

Further, the amount of soil movement is adjusted by the front soil cutting blade 7 fixed to the lower part of the soil moving plate 5. Furthermore, in order to improve the performance of soil movement, a soil feeding screw conveyor 10 is attached to the rear of the soil moving plate, which works to provide a stable film coating regardless of the soil conditions, whether it is dry or humid.

〔Example〕

A horizontal rod 22 is provided behind the mounting rod 27, and a treading wheel arm 19 and a groove pear adjustment arm 26 are fixed to the horizontal rod 22 to a sliding tube 2o that can be inserted and removed, and the sliding tube 2° is slidable. It can be installed in a fixed manner. A groove star adjusting arm 26 is fixed to the sliding tube 2o, and a groove star l is fixed to the groove pear adjusting arm 26 so as to be vertically adjustable. Large tread width support rod 13 and small tread width support rod 14
springs 15 and 16 were installed. Treading wheel small support rod 1
Fix the L-shaped film reversing rod 4 near the grounding part of 4,
The film reversing rod 4 is provided with a joint 9 that moves up and down.

Furthermore, a pipe 3o is fixed to the soil moving arm sliding pipe 21 to attach the soil moving plate arm, and the soil moving arm 12 is vertically adjustable.
It is fixed so that it can be adjusted up and down. The soil moving plate arm 12
As shown in FIGS. 1 and 2, a semicircular arc-shaped film reversal auxiliary rod 6 and an earth moving plate 5 are fixed, and a soil cutting front blade 7 is vertically adjustable at the bottom of the earth moving plate 5. It stopped. There is also work to move and cover the earth. The method of coating the film is shown in FIG. 4, in which the film is driven via a power transmission cable 23 from a transmission 24 fixed to a five-row machine 25 such as a tiller. A ruler wheel 8 and a film covering width adjusting rod 11 are fixed to the rear of the soil moving arm 12, and the ruler wheel 8 is attached so that its height can be freely adjusted.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

Since the entire surface can be covered with the film, there is no scattering of toxic gas after soil disinfection, and the amount of chemicals required is small, resulting in a large soil disinfection effect.

Sakumousei 1 has a one-sided shape that pushes the soil inward, and at the same time,
Since the tip of the groove star 1 is curved inward (see Figure 2), it is possible to cover the entire surface of the film by performing back and forth operations, and even if the groove star 1 comes into contact with the existing film 32, the film will not be damaged. It cannot be broken. Furthermore, when covering the film, the large tread pressure width 2 and the small tread pressure wheel 3 are used to press and cover the film, thereby preventing the film from peeling off due to wind and rain.
