Description

Detailed Description of the Invention (a) Industrial Application Field The present invention is a composite mulcher that forms ridges for crop cultivation, covers the ridges after sowing seeds, and promotes the growth of crops. It is related to.

(b) Conventional technology It is generally known that ridges are formed by using earthenware that slopes from the left and right toward the center, and a composite mulcher that covers the surface of these ridges by laying a vinyl sheet is known as It exists in Publication No. 41617.

(c) Problems to be Solved by the Invention In the conventionally known composite mulcher, the ridges are formed using a molding machine, and then a vinyl sheet supported by a support member is placed on the surface of the ridges using a guide roll and a feed roll. After laying the vinyl sheet and covering the ridges with this vinyl sheet, the seeds are sown by manually punching holes in the sheet, but as mentioned above, because the sheet is laid only by guide rolls and feed rolls, the sheet may become loose during laying. There is a problem that gaps are created between the surface of the ridges and the sheet, which reduces the effectiveness of the sheet covering by half, and there is also the hassle of having to sow the seeds manually after laying the sheet.

(d) Means for Solving the Problems In order to eliminate such problems in the conventional art, the present invention provides a method for forming ridges by using a ridge former equipped with a sloughing means and a leveling means when the vehicle is being towed by a tractor or the like. At the same time, the seeds are sown using a guide tube that guides the seeder tape, which supports the seeds on the tape, from the reel into the ground at the top of the ridge, and the sheet of the winding member that supports the raw vinyl sheet with holes drilled to match the seeds is placed in the center. An invention in which the sheet is bent through an expansion frame that extends in the traction direction, is laid under sufficient tension to avoid wrinkles, is pressed with a pressure roll, and is pressed down on both sides with a sheet presser ring while being rolled by a rotating disk. The purpose is to improve workability and tension the vinyl sheet.

(E) Operation The machine frame moves forward while being towed by a tractor, etc., and as it moves, the seeder tape from the reel supported by the reel holder provided on the tractor connecting member of the machine frame passes through the guide tube and the mulch plate. It sinks into the soil of the ridge formed by a ridge shaper made of a soil leveling board, etc., and continuously feeds and sows seeds while scraping the soil. A vinyl sheet with holes made to fit the seeds held in the cone is passed through an expansion rod under tension, and the sheet is laid on the ridge where the seeds were sown using seeder tape, and the sheet is pressed down by a pressure roll that presses the seed into the soil using the force of a spring. This vinyl sheet is press-fitted into the sides of the ridge formed by the subsequent left and right presser wheels so as to cover the ridge, and the edges are covered with the soil by a rotating disk, and the covered vinyl sheet is To increase the soil temperature while keeping the temperature constant, and to prevent fertilizer applied to the soil from flowing out, thereby contributing to the growth of crops.

(F) Embodiment Next, an embodiment of the composite mulcher according to the present invention will be specifically described with reference to the accompanying drawings.

Reference numeral 1 denotes a machine frame, and a towing vehicle T is connected to a towing connecting member 3 protruding from the hollow horizontal frame 2 so that the machine can be towed. The hollow horizontal frame 2 has telescopic members 2a, 2 extending left and right.
a is inserted, expands and contracts, and is fixed at a predetermined position with a bolt or the like.

At the ends of the telescopic members 2a, 2a, cones 4b, 4b for holding the original vinyl sheet +-p are provided opposite to the tips, and the proximal ends of digit arms 4.4 are attached. cone 4b,
4b is fitted into pins 4a, 4a attached to arm 4.4, and biases spring 5.5 in the clamping direction. Further, a holding cylinder 6 is attached to the horizontal frame 2 in the vertical direction, and a reel holder 7 is attached to the connecting piece 3 inside the holding cylinder 6 of 2.
A guide cylinder 1o for guiding the seeder tape 9 from the reel 8 held by the holder is dammed and fixed with a knob bolt 11.

The tip of the guide tube 10 is bent, and the tip is made to look through so as to sink down onto the surface of a ridge formed by a ridge former 12, which will be described later.

Further, on the left and right side frames 13 and I3 of the machine frame 1, a seat expansion rod 14 whose center is curved and extends in the direction of travel is attached to a support piece 15.
Cone 4b of arm 4.4 attached via.

The vinyl sheet (P) held for 4 hours was guided and laid while being tensioned and stretched in the left and right direction. Support pieces 16.16 are attached to the expansion rod 14 with gaps left and right, and the middle part of the bearing member 18 that supports the pressure roll 17 is supported on this support piece 16.16. A spring 19 interposed between the end portion and the branch piece 16 is used to press down the seeds of the seeder tape 9 and the vinyl seed +-p from above toward the ridge using a pressure roll 17. Further, the ridge forming device 12 is provided on the front end side of the machine frame 1. The ridge forming machine has the front and lower parts open, and the upper surface and left and right sides are gradually sloped to form a groin plate 12a and a facing plate 12b, and the front of the upper facing plate 12b is extended to form a cover plate 12C. The cover plate 12C of the holder 2 is configured to have a notch 20 sandwiching the connecting piece 3 therebetween so as to be guided by the connecting piece 3, and furthermore, this forming device 12 has a notch at the rear and a notch 20 is inserted into the notch. The tip of the guide tube 10 is positioned and suspended by a spring 22.22 between a support piece 2121 from the side frame 13.13 of the machine frame 1. Also, side frame 1 of machine frame 1
3.13, the middle part of the bearing member 24 which has the seat push ring 23 supported at its tip end thereof is supported, and a spring 25 is interposed between the other end of the bearing member 24 and the side frame 13.13. This spring 25 acts on the presser ring 23 in the pressing direction. Furthermore, an inclined rotating disk 26, 26 is attached to the rear end of the side frame 13, 13 so as to be adjustable on a screw shaft 27.

(g) Effects The present invention is provided with a ridge forming device which is open at the front and bottom of the machine frame and is composed of a mulching board and a leveling board, and the machine frame is advanced by a compound ratio such as a tractor. At the same time, the ridges can be formed easily, and furthermore, after the ridges are formed, the seeder tape held by the seeder reel holder installed on the machine frame is guided onto the ridge through the guide tube to sow seeds and to make the ridges longer in the lateral direction. A vinyl sheet (with continuous openings) P is laid on top of the sown seeds by stretching it from side to side using an expansion rod, and this is pressed down with a pressing roll to cover it, and then both ends of this sheet are held down with pressing rings. Since the soil layer is applied to the edge using a rotating disc, the work can be done continuously while the vehicle is traveling, and since the sheet is laid in close contact with the surface of the ridge, the effect of laying the sheet can be thickened (increased). can.
