Description

[Detailed description of the invention] "Industrial application field" This invention continuously delivers a sheet to cover high ridges for potato or tobacco cultivation formed by ridge forming plates, and stretches the sheet over the ridge surface. The present invention also relates to a triple-type mulch work device that embeds both side edges of the sheet into the soil on both sides of the ridge.

``Prior Art'' Among this kind of multi-working devices, there is one described in Japanese Utility Model Publication No. 57-49606, for example, but there is no triple-unit type.

``Problems that the invention aims to solve'' In such a triple-barreled structure, when a long sheet roll is incorporated without interference, there are drawbacks such as the front-to-back length and left-right width of the work equipment. Not only that, but also the front-rear and left-right balance was poor.

``Means for Solving the Problems'' Therefore, the present invention provides a structure with a multi-unit that covers and stretches a sheet over the ridge surface formed by a ridge forming plate via a pressure roll. A multi-unit consisting of three units on the center and left and right sides is installed at the rear, and the seat rolls of the left and right multi-units are offset with respect to the seat roll of the central multi-unit so that they wrap at the same position in the front or rear direction. It is composed of

"Function" According to the present invention, it is possible to incorporate the sheet roll into the working machine compactly and with good left-right balance, thereby making the overall structure of the working machine more compact and improving the workability in multi-tasking operations. Improvements can be made.

19 in the figure is a synthetic resin sheet 20 on the high ridge 15.
It is a multi-working machine that covers the machine, and is equipped with three multi-units 21a, 21b, and 21b in the center and on the left and right sides.

As shown in FIG. 3, an L-shaped main frame 24 is provided, the front end of which is removably and positionally adjustable fixed to the horizontal frame 22 at the upper rear side of the ridge work machine 14 through a mounting member 23. Receiving member 25
A pair of horizontal culms 26 are supported for each unit through the horizontal position adjustment, and each unit 21a, 21
A pair of horizontal culms 2 facing left and right in b, 21b
A sheet roll 20a is suspended between 6 and 26, and a sheet receiving roll 27 is placed below the roll 20a.
is positioned so that the sheet 20 fed out from the sheet roll 20a is guided and supported by the sheet receiving roll 27.

Further, the support rod 29 of the pressure roll 28 attached to the upper surface of each high ridge 15 is connected and supported by the horizontal frame 22 via the vertical rod 30 and the connecting rod 31, and the vertical rod 30 is connected to the connecting rod 31 by an adjusting member. 32
At the same time, the connecting rod 31 is fixedly supported on the horizontal frame 22 via a mounting member 33 so as to be detachable and position adjustable. It is supported at the center via a horizontal rod 34.

Further, a gauge wheel 37 is fixedly supported at both left and right ends of the horizontal frame 22 via a mounting member 35 and a vertical rod 36, and is detachable and adjustable in left and right and height. A pressing wheel 39 that presses both side edges of the sheet 20 against both sides of the ridge 15 and a soil covering wheel 40 that places soil on both side edges of the sheet 20 and embeds it are supported so as to be able to swing up and down.

Furthermore, adjacent soil covering rings 40, 40 in the center
A soil covering plate 41 is provided between the soil covering wheels 40 to assist the soil covering ring 40, so as to eliminate soil left behind in the gap between the soil covering wheels 40, 40.

By the way, the horizontal frame 22 is such that the entire multi-working machine 19 is fixedly supported by the transmission case 18 and the right end side plate 43 of the rotary cover 42 via a mounting plate 44 so as to be detachable and lateral position adjustable.
The mounting plate 44 is fixedly supported by the transmission case 18 and the side plate 43 via bolts 45, and the horizontal frame 22 is fixedly supported by the mounting plate 44 via bolts 46, so as to be compatible with different types of tractors. In addition, each unit 21
By making a, 21b, and 21b individually removable, it is configured to enable multi-work in one to two ridges.

FIG. 4 is an explanatory diagram showing how the rotary claw 17a of the working machine 14 can be attached and detached and the left and right position can be freely adjusted so as to correspond to each unit 21a, 21b, 21b. An outer shaft 48 on which a rotary claw 17a is implanted is attached to the shaft 47 via a bolt 49 so as to be able to adjust the left and right position in correspondence with the formed ridge.

FIG. 5 is an explanatory view showing the horizontal and vertical adjustment of the molded plate 16. A rear cover 51 is connected to the rear side of the rotary cover 42 via bolts 50 so as to be vertically adjustable. The forming plate 16 is connected to the forming plate 16 via bolts 52 so that the left and right positions can be adjusted freely, and the auxiliary forming plate 53 is connected and supported to the forming plate 16 via the bolts 54 so that the protrusion length can be adjusted freely.

By the way, as shown in FIGS. 1 and 3, the central multi-unit 21a is disposed between the left and right rear wheels 5, 5 of the tractor 1, and the center positions of the left and right multi-units 21b, 21b are arranged at the left and right rear wheels. The wheels 5, 5 are disposed outside the locus so that the wheels 5, 5 can safely run through the furrows without stepping on the previously planted seed potatoes during potato work.

Furthermore, with respect to the sheet roll 20a of the central multi-unit 21a, the left and right multi-units 2
The sheet rolls 20a of 1b and 21b are arranged so as to wrap in the same rear direction, and the front and rear space of the sheet rolls 20a in the working machine 19 is minimized, so that the sheet rolls 20a can be stored compactly in the working machine 19 with good left-right balance. The structure is such that these sheet rolls 20a can be assembled.

The present invention is configured as described above, and the tractor 1
The ridge work machine 14 and the multi work machine 19 are pulled by the PTO output of the tractor 1, and the disc rotor 17 is driven by the PTO output of the tractor 1. A high ridge 15 is formed by the forming plate 16, and the sheet 20 fed out from the sheet roll 20a mounted on the horizontal culm 23 is sent to the lower side of the pressing roll 28 and pressing wheel 39 via the rear sheet receiving roll 27. The side edge of the sheet 20 that has been fed and pressed by the pressing wheel 39 is covered with soil by the soil covering wheel 40, and the ridge 15 is
It is covered with

Therefore, during work, each multi-unit 2
The center of 1a, 21b, 21b is the left and right rear wheels 5,
Since it is located outside the locus 5, the inconvenience of trampling on crops such as seed potatoes that have been planted earlier is eliminated, and good mulching work is performed.

Further, since the three-roll sheet roll 20a is incorporated into the multi-work machine 19 with a compact longitudinal length and good left-right balance, overhang of the work machine 19 is prevented.

"Effects of the Invention" As is clear from the above embodiments, the present invention employs the multi-units 21a and 21b to cover and stretch the sheet 20 on the surface of the ridge 15 formed by the ridge forming plate 16 via the pressure roll 39. , 21b, multi-units 21a, 21b, 21b, 21a, 21b, 21b, 21a, 21b,
21b, and the central multi-unit 21a.
Since the sheet rolls 20a of the left and right multi-units 21b, 21b are offset so as to wrap at the same position in the front or rear direction, the sheet rolls 20a are inserted into the work machine 19 in the front and rear direction. By minimizing the space required for compact construction and with good left and right balance, this work machine has remarkable effects such as being able to prevent overhang.
