Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a mulch work machine that forms ridges in cultivated land and stretches a film on the ridge surface. To provide a mulch work machine that can easily adjust the interval between mulch members in accordance with changes in the mulch members, and can pressurize the ridge surface using a lightweight leveling plate.

[Prior art and its problems]

Conventional mulch work machines have side rods fixed to both ends of a frame pipe and a pressure roller and mulch member mounted thereon, and the pressure roller presses the ridge surface and stretches the film on top of it, which reduces the ridge width. If you try to adjust the spacing between the mulch members due to changes, you will have to replace the pressure rollers, making it troublesome to adjust the spacing between the mulch members, and using a heavy pressure roller, which will result in a large load. become.

[Structure of the idea]

The multi-purpose work machine according to the present invention has a frame pipe connected to the hitch fittings of the machine body, a main pipe in the center, and sub pipes that are inserted into both sides of the frame pipe and fixed in an adjustable manner. Grooving plates to be placed on the auxiliary pipe are removably attached near both ends of the auxiliary pipe, and a core bar, a tension wheel, and a cover plate for holding the film roll are mounted on the side rods fixed to both ends of the auxiliary pipe. A leveling plate is installed on the front side of the frame pipe with a downward slope at the rear, and the support arm of the leveling plate is connected with a pin to a suspension rod protruding from the main pipe, and the leveling plate is detachably suspended. The spring that presses the trailing edge against the ridge surface is hooked onto an adjustment rod that passes through a protrusion on the main pipe.

In this invention, the groove cutting plate can be attached and removed depending on the soil, and by simply inserting and removing the sub pipe from the main pipe and replacing the leveling plate and film roll, ridges can be created according to the desired ridge width. Since a lightweight flat plate is used, the load can be reduced, and the strength of the spring acting on the flat plate can be easily adjusted. Furthermore, in this invention, the leveling plate is made of stainless steel to prevent soil from adhering to it, and both ends of the trailing edge are bent diagonally downward, thereby forming slopes at both ends of the ridge surface to allow rainwater to drain away. This made it flow better.

The embodiment of the present invention has the above-mentioned configuration, and when the operator drives the tailor with the operating handle 4 pushed out diagonally rearward, the groove cutting plates 16, 16 move along the wheel marks A, A, cut the side ditch, and cut the tilled soil. is removed outward to form a ridge B, and the rear edge of the leveling plate 40 advances while applying pressure to the upper surface of the ridge B to flatten it. Next, film F has ridges B
The wheels 32, 32 roll on both sides of the wheel. The tension wheel has an eight-figure shape that opens backwards, so
Gives film F a tendency to spread outward,
Therefore, the film covers the ridges without wrinkles. Subsequently, the soil covering plates 38, 38 roll to cover both sides of the film F with soil to prevent the film from turning over. Since the tension wheel 32 can swing around the support shaft 30, if the bottom surface of the side gutter is uneven, it will escape upwards and prevent the film from being broken. If the soil is soft, the groove cutting plates 16, 16 are removed and the film is stretched using the side grooves dug by the drive wheels 3, 3.

In this example, when the ridge width changes, bolt 1
3, 13, insert and remove the sub pipes 12, 12 from the main pipe 11, adjust the interval between the groove plates 16, 16 to the desired ridge width, and adjust the pin 46 accordingly.
is removed and the leveling plate 40 is replaced, and since the interval between the side rods 21, 21 also changes, the film winding product 28 is replaced. In this way, the sub pipe 1 is connected to the main pipe 11.
2 and replacing the leveling plate 40 and the film roll 28, it is possible to create ridges and stretch the film according to the desired ridge width. In this embodiment, a rectangular leveling plate 40 is provided on the front side of the frame pipe 10 with a downward slope at the rear, this leveling plate is suspended from suspension rods 45, 45 protruding from the main pipe 11, and a spring 50 is attached to the leveling plate 40. The rear edge is brought into pressure contact with the ridge surface by applying pressure to the ridge surface, and the ridge surface can be pressurized and leveled with a member that is extremely lightweight compared to conventional pressure rollers. Furthermore, since the leveling plate 40 is made of stainless steel, it is difficult for soil to adhere to it, and therefore, a beautiful ridge surface can be formed.

Next, in this embodiment, a spring 50 acting on the leveling plate 40 is attached to an adjusting rod 47 that passes through a protrusion 48 on the main pipe.
This adjusting rod is adjustable with a snap pin 51, and when the snap pin 51 is inserted into one of the small holes 49, the strength of the spring 50 changes, so that the leveling plate 40 can be lowered against the ridge surface. The force can be adjusted very easily. Moreover, the corner end of the rear edge of this flat plate is bent diagonally downward to form a triangular inclined piece 41,
41, and this inclined piece presses down and inclines the outer ends C, C of the ridge surface, so that rainwater flows better and water does not accumulate on the ridge surface.

The above describes one embodiment of the present invention, and the present invention is not limited to this embodiment, and the design can be changed within the gist of the invention. For example, the frame pipe 10 may be connected to a tractor instead of a tailor. Good too.

In this invention, the frame pipe connected to the hitch fittings of the fuselage is composed of a main pipe in the center and sub pipes that are adjustable and fixed on both sides of the main pipe. It is detachably attached to both ends of the pipe, and the core bar, tension wheel, and soil cover plate for holding the film roll are mounted on the side rods fixed to both ends of the sub-pipe, and the rectangular leveling plate is attached to the side rods that are attached to the side rods that are fixed to both ends of the sub-pipe. The support arm of the leveling plate is installed on the front side of the frame pipe at an angle, and the support arm of the leveling plate is connected with a pin to a suspension rod protruding from the main pipe, and the leveling plate is removably suspended, and the rear edge of the leveling plate is pressed against the ridge surface. A spring is hooked onto an adjustment rod that passes through a protrusion on the main pipe, and this configuration allows the groove cutting plate to be attached and removed depending on the soil, allowing the sub pipe to be moved in and out of the main pipe and evenly removed. By simply replacing the flat plate and the film roll, you can create ridges according to the desired ridge width and stretch the film, making it extremely easy to adjust the spacing between mulch members, which can be troublesome during mulching work, and making it lightweight and even. Since a flat plate is used, no extra load is applied, and the strength of the spring acting on the flat plate can be easily adjusted. In addition, if the leveling plate is made of stainless steel and both ends of the trailing edge are bent diagonally downward, soil will not stick to the leveling plate, and slopes can be formed at both ends of the ridge, allowing rainwater to flow better. It has the advantage that water does not accumulate on the ridged surface.
