Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a mulch device that covers ridges formed by a ridge shaper with a mulch film.

Conventionally, the ends of the mulch film covering the ridges have been fixed by making the edges of the mulch film adhere to the ridge base using a pressure wheel and then covering the film with soil using a soil covering device.

By the way, when covering a plurality of ridges with mulch film at the same time, a pair of treading wheels and a soil covering device are provided at the bases of the left and right ridges between adjacent ridges, as well as on both sides of adjacent ridges. However, when a rotatably supported soil covering disk is used as a soil covering device, soil becomes clogged between the left and right soil covering disks, which often impedes rotation of the soil covering disk.

The purpose of this invention is to provide a multi-device capable of solving the above-mentioned problems.

This idea consists of mulch films that are pulled out along adjacent ridges and are wound into rolls and held in parallel, with tread wheels that press against both ends of these mulch films and soil covering arranged behind them. A pair of soil covering bodies are provided on the left and right sides, and two soil covering disks rotatably held are used as the soil covering body located at least in the center of adjacent ridges, and the front center of the soil covering disks is located behind the treading wheel. The present invention is characterized in that a soil removal plate is provided that divides the soil between the sections into left and right sides.

In other words, by separating the soil between sections using the soil removal plate, it is possible to prevent soil from clogging between the soil covering disks that are close to each other between sections, and to prevent the rotation of the soil covering disks from being obstructed by this, thereby ensuring the soil covering action on the mulch film. In addition, since some of the soil collected by the earth removal plate passes through the inside of the treadling wheel and is placed on the mulch film, the mulch film is wrapped in the soil by covering with the soil covering disc and the mulch film is securely fixed. It is configured so that it can be done.

An embodiment of this invention will be described with reference to the drawings.

1 is a tractor body, only a part of which is shown, and a tilling device 2 is connected to the rear of the tractor body.

Support frame 3 provided at the rear end of this tilling device 2
Two sets of ridge shapers 4 on the left and right are attached to the ridge shaper 4.

5 is a tail wheel frame pivotally supported on a support shaft 7 fixed to the transmission case 6 of the tilling device 2; and a tilling depth adjustment handle 8.
A hitch bar 11 is attached to the rear end of the tail wheel frame 5, which holds tail wheel support rods 10', which pivotally support the tail wheel 9 at the lower end, at both ends thereof.

Next, holding pipes 12 are provided on both sides of the hitch bar 11.
are held, and a film support 14 that holds a multi-film 13 wound into a roll and a roller support 16 that holds a sponge-like guide roller 15 are attached to these holding pipes 12, respectively.

In addition, the tail wheel support rods 10 attached to both sides of the hitch bar 11 have support frames 17 pivoted at their tips while being urged downward, and these support frames 17 have spongy outer circumferences. A treading wheel 18 and a soil covering disk 19 which is a soil covering body are attached.

Therefore, the ridge 20.2 formed by the ridge shaper
A center support frame 23 is located between two parts 22 of the hitch bar 11 and is pivoted to the lower end of a center pipe 24 attached to the center of the hitch bar 11 so as to be biased downward by a spring 25 and to be movable up and down.

A mounting plate 26 is fixed to the rear end of the center port frame 23, and holding pipes 27 are fixedly fixed to both sides of the mounting plate 26 by fixing bolts 28.

A treading wheel holding frame 29 is fixed to the front surface of these holding pipes 27, and a mounting plate 30 is fixed to the rear surface thereof.

A tread wheel 31 having a spongy outer periphery is pivoted on the tread wheel support frame 29 and is urged downward by a spring 32 so as to be movable up and down.

Next, an outer cylinder 34 is fixed to the mounting plate 30 for rotatably holding the soil covering disk holding pipe 33.

A fixing plate 35 is fixed to the outer cylinder 34, and a fixing screw 38 inserted through a long hole 37 of a rotating plate 36 fixed to the upper end of the soil covering disk holding pipe 33 is screwed into the fixing plate 35.

A soil covering disk 39 is rotatably supported at the lower end of the soil covering disk holding pipe 33.

The rotation axes of the pair of left and right soil covering disks 39 are determined so that they are inclined outward toward the enemy with respect to the vertical plane and expanded toward the rear.

That is, the contact point between the left and right soil covering disks 39 is the front lower part of the outer peripheral surface of the soil covering disk 39.

Further, a soil removal plate 40 is attached to a support rod 41 fixed to the center support frame 23, located at the front center of the two soil covering disks 39 and behind the left and right treading wheels 31.

Reference numeral 42 denotes a groover for forming a groove by scraping a part of the base of the ridge 20.21, and is held by a mounting plate 43 fixed to the center pipe 24.

In such a weeding process, two ridges 20.degree. 21 are simultaneously formed by the ridge forming device 4 after the tillage is done by the tilling device 2.

Subsequently, the mulch film 13 is guided by the guide roller 15 and unwound to cover the ridges 20, 21.

Then, the outer end of the mulch film 13 is covered with soil by the tread wheels 18 and the soil covering disk 19, which are arranged at the outer base of each of the ridges 20, 21.

Therefore, between the parts of the ridge 20.21, a part of the base of the ridge 20.21 is scraped off by the trench excavator 42, and soil is accumulated in the center part, and then in the groove formed by the trench excavator 42. The foot of the mulch film 13 is pressed by the treading wheel 31 running on the treadle.

The soil piled up in the center is moved to the side by the soil removal plate 40 located at the center of the left and right tread wheels 31, and a part of it passes through the inside of the tread wheels 31 and is placed on the mulch film 13. be done.

Thereafter, the soil is covered from above while moving the soil toward the base using the soil covering disk 39.

That is, the inner end of the mulch film 13 is treated by passing a small amount of soil onto the mulch film 13 through the inside of the treading wheel 31 using the earth removal plate 40 at the place pressed down by the treading wheel 31, and temporarily fixing it.

Next, the soil is collected by the soil covering disk 39, and the soil is dropped from above with the temporarily fixed soil contained therein, that is, a small amount of soil is enveloped by the inner edge of the mulch film 13, and the base of the ridge 20° 21 is removed. By wrapping the ends of the mulch film 13 around the soil, complete soil covering is achieved.

Thus, the soil removal plate 40 moves the soil in the center of the space 22 to both sides, thereby preventing soil from entering and clogging the space between the soil covering disks 39 that approach each other on the left and right, thereby inhibiting the rotation of the soil covering disk 39. There is.

Since this idea was stolen as mentioned above, the base of the ridge can be reliably covered with soil by preventing soil from clogging between the left and right soil covering disks, which are close to each other, and by ensuring smooth rotation. At the same time, the soil in the center can be moved to the sides to ensure that the soil is covered by the soil covering disk.
In addition, some of the soil collected by the earth removal plate passes through the inside of the treadling wheel and is placed on the mulch film, so the mulch film is wrapped in the soil by covering with the soil covering disk, and the mulch film can be fixed very reliably. It has the following effects.
