Description

[Detailed description of the invention] Industrial applications The present invention relates to a mulch film laying device.

Conventional technology and problems to be solved by the invention In a mulch film laying device that covers the soil surface, a roll of mulch film such as a vinyl sheet is rotatably supported by a reel, and the back of the mulch film is The mulch film is moved forward while pressing the mulch film surface against the soil surface using a rotating pressing shaft, pressing roll, etc., which rotates while pressing against the soil surface, and the mulch film is pulled out from the reel and laid. Each time this kind of laying work goes back and forth within the field, the mulch film is cut at the edge of the field, and at the beginning of the first step, the mulch film is pulled out in advance and held under pressure by a suppression shaft, etc. After that, move the machine forward and start the laying work. Since such operations are performed with one machine temporarily stopped, it is difficult to manually cut the mulch film, pull it out from the reel, etc., and it is difficult to perform it accurately.

Means for Solving the Problems The present invention provides a feeding device (2) that can feed out the mulch film (1) by sandwiching the film surface of the mulch film (1) to a drawer section of the mulch film (1) laid to cover the soil surface. ), and a cutting device (3) that cuts the mulch film (1) on the side where the mulch film (1) is fed out from the position where it is held by the feeding device (2) after being pinched by the feeding device (2). shall be.

Function and effect of the invention When laying the mulch film (1), use the feeding device (2).
) If the film surface grip of mulch film (1) is released, the leading end of the mulch film (1) is already laid on the soil surface, so as one machine moves forward, the drawer part will be pulled out backwards one after another. . Once the laying is finished at the edge of the field, etc., the forward movement of the machine is stopped and the laying part side is cut off from the mulch film (1) in the drawer part. The film surface of step 1) is clamped, and after this clamping, the cutting device W (3) acts on the feeding side behind the clamping position to cut the film. Stay in this locked state
Because the feeding device (2) feeds out the mulch film (1), the mulch film (1) is less likely to be disturbed at the drawer or cut end, and this feeding is less likely to be inaccurate, and the operator should not be in the cockpit etc. It can be easily operated by remote control.

Embodiment In the illustrated example, the laying device connected to the tractor is
The reel (1) is a roll of multi-film (1) made of vinyl sheet that is supported horizontally on the mounting machine frame (4).
5), Sponge-like pressure shafts (7) that are rotatable in contact with each other and located in the respective soil cultivation grooves (6) in the rear and lower part, between these reels (5) and the contact portions of the pressure shafts (7); A feeding device (2) consisting of a pair of upper and lower feeding rolls (8) (9) provided at the drawing part of the mulch film (1), and cutting this mulch film (1) at the feeding side of the feeding roll (81 (9)). The cutting device (3) is made of nichrome wire.

A feed roll (9) of the feed device (2) that receives and guides the lower surface of the mulch film (1) is rotatable around a horizontal axis and is provided at a fixed position. The upper feed roll (8) facing this is rotated around the horizontal axis a at the tip of the arm OD which is pivoted to the mounting machine frame (4) so as to be movable up and down around the drive shaft 01. The drive shaft (11
is provided to be driven by a motor (+31).

The sprocket (b) provided on the drive shaft 0Ill and the sprocket 09 on the shaft (rotation) are provided so that transmission is transmitted by a chain drive (IQ), and the feed roll (8) is rotated by this motor (1 m electric switch). and then remove the lower feeding roll (9
) The mulch film (1) held between the two is fed out to the rear side. Further, the arm 0υ is constantly tensioned by a spring (171) in a direction to separate the feed roll (8) upward from the upper surface of the mulch film (1).

In addition, the above-mentioned feeding roll (8) has a pressure shaft (
It is also possible to use a belt (to) for transmitting power between the pulley Oa provided on the shaft of 7).

The nichrome wire that is the cutting device (3) is cut into the reel (5).
It is provided laterally in parallel with the feed roll (9) at the lower part of the arm (9) which is rotatable about the axis of the roll, and can be made red hot by applying electricity. A wire 121) is connected to the upper end of this arm (to), and the nichrome wire of arm 12G is rotated up and down by remote control using a control lever near the cockpit of the tractor aδ to heat the multi-film (1). It is configured to disconnect.

In addition to this cutting device (3),

The feed roll (8) is moved downward against the spring (■) to be held in contact with the upper surface of the mulch film (1), and at the same time as the cutting device (3) cuts the feed roll (8), the motor (13 It may be configured so that the multi-film (1) is fed out to the rear side at the same time as the cutting.
Further, each of these parts may be operated by a separate operation interlocking mechanism.

(to) is a tilling device, 124 is a conveyor that scoops up the tilled soil immediately after tilling and supplies it to hopper 4, @ is a compaction shaft (
7) This is a chute that pushes down the laid mulch film (1) to the rear. (5) is a soil cultivator that shapes the tilled soil surface into a soft part (end) and a groove part (6), (21 is a gauge foil). Each of these devices is the laying device (2) at the rear end.
It is also connected to the rear of the tractor (■).

As the tractor moves forward, the mulch film (1) of the reel (5) is placed on the soil surface shaped by the tiller (5).
is pulled out rearward, and each groove part (6
), and is stabilized by being pressed down by the pressing soil flowing down from the upper chute 4. When turning back after the forward stroke, the tractor (stops the advance of 2a and rotates the arm 4 via the wire) will move the feed roll (8).
moves downward to sandwich the mulch film (1) between it and the lower feeding roll (9), and the cutting device (3) cuts the mulch film (1) from the nipping position to the feeding side, and then By driving this feed roll (8), the feed roll (9)
The mulch film (1) sandwiched between the two is fed out to the rear side.

In this way, when the multi-film (1) is sandwiched between the feed rolls (81(9)) and the turn is turned and the work is started on the backward stroke, the feed rolls (8) are driven for an appropriate time while moving forward. When the mulch film (1) is fed out, it is pressed by the pressure shaft (7) on the rear side as it is being laid, and when the laying starts, the feeding roll (8) is separated upward,
The multi-film (1) is pulled out by suppressing the film surface by the suppression wheel (7) and advancing the aircraft.
