Description

[Detailed explanation of the idea] (b) Industrial application fields This invention relates to a land leveling and compacting device for a sub-scrap machine.

(b) Conventional technology When carrying out grading of paddy fields, it is ideal to supply an appropriate amount of water into the rice field over a certain period of time so that the soil contains an appropriate amount of moisture, and then perform grading. Since this is usually difficult due to weather conditions, it is often necessary to supply a large amount of water all at once.

Therefore, the ratio of muddy water in rice fields is larger than that of muddy soil.

Under these circumstances, surrogate soil work is carried out, but
Conventionally, the compacting device of a sub-scraping machine has an elastic rectangular plate-like body (41768 Utility Model Publication No. 48-4176), and a bar-shaped leveling rod that protrudes from the rear side of the compacting plate to form a comb-like shape. A crushing device for a soil crusher (Utility Model Application No. 52-85710) was known.

(c) Problems to be solved by the present invention However, even if it has elasticity, if the pressure plate is rectangular, the muddy water will push up the pressure plate, so the muddy water will not be effectively leveled out. Ta.

In addition, contaminants such as straw and stumps cannot be pushed into the muddy soil and float on the surface of the muddy water, which has the disadvantage that they become entangled with the planting tweezers of the rice transplanter, which is a post-work step.

Furthermore, a large amount of muddy water accumulates on the suppression plate, which places a large load on it and increases traction resistance, which hinders work.In addition, the muddy water pushed by the suppression plate flows out to both ends of the suppression plate, sending out crushed soil and mud. The disadvantage was that it was difficult to level the land because of the unevenness.

In addition, even if the compaction device of a sub-scraping machine has a bar-shaped leveling rod that protrudes from the rear side of the compaction plate and forms a comb-like shape, if the compaction plate has the same thickness, the mud will not flow out smoothly. If the grading rods were not buried and fixed to the suppression board, foreign matter could become entangled.

2) Means for solving the problem This invention consists of a ground leveling plate rotatably attached to the sub-soil crushing machine, a pressure plate connected to the leveling plate and made of an elastic material, and a pressure plate protruding from the rear side of the pressure plate. A compacting device for a sub-scraping earth machine having a bar-shaped soil leveling rod forming a comb-teeth shape, characterized in that the rear side of the compacting plate is thin, and the bar-shaped leveling lever is embedded and fixed in the compacting plate. Provides compaction equipment for soil crushing machines.

(E) When the plowing soil crusher is driven forward and plowing work begins, the crushed soil is pushed by the leveling plate and the pinning plate, leveling the muddy ground.

At this time, the leveling rod guides and buries foreign matter such as rice stumps, weeds, and compost scattered on the surface of the muddy water into the soil without getting tangled. It moderately suppresses the water and flows out easily from the ground leveling breakthrough.

(f) Example Next, the configuration of this invention will be explained based on the drawings of the example. 1 is a substitute soil crusher.

The substitute soil crusher 1 is composed of a machine frame section 2, a soil crushing section 3, and a land leveling section 4, and is connected to the rear part of the tractor body (not shown) by a top link 5 and a pair of lower links 6.

The machine frame section 2 includes a cylindrical machine frame 7 containing a transmission shaft, a transmission case 8 provided at one end of the machine frame 7, a case 9 provided at the other end, and a mission case 10 provided at the center. It consists of

The crushing section 3 includes a rotary type crushing body 11 and a cover 12 that covers the top of the crushing body 11, and the rotating shaft of the crushing body 11 is supported by bearings of the transmission case 8 and the case 9.

The ground leveling and suppressing unit 4 includes a leveling plate 13, a leveling device 14, a support arm 15 that supports and rotates these, a suspension rod 16, an adjustment rod 17,
It consists of a shaft 18.

The ground leveling plate 13 is shaped like a plate with approximately the same width as the cover 12.
It is rotatably connected to the rear side of the cover 12 with several hinges 19.

A pair of support arms 15 are rotatably attached at one end to the machine frame 7,
It is installed almost horizontally towards the rear.

The shaft 18 is installed between the other ends of the pair of support arms 15, and is connected and supported by the top link 5 by an adjustment rod 17.

The suspension rod 16 has an upper end rotatably connected to the other ends of the pair of support arms 15, and a lower end rotatably connected to a connecting protrusion 20 protruding from the rear of the ground leveling plate 13.

21 is a stopper bundle, which is attached to the upper part of the adjustment rod 17.

The suppression device 14 is formed of a suppression plate 22 and a leveling rod 23.

The suppressing plate 22 is made of a strong hard rubber material with an appropriate thickness and is shaped to have approximately the same width as the leveling plate 13, and its front side is fixed to the rear side of the leveling plate 13 with bolts 24.

Reference numeral 25 denotes a connecting auxiliary material such as a washer buried in the front side of the pressing plate 14.

At the rear side of the suppressing plate 22, the back surface of the plate is shaved with a width of less than half the plate radius (approximately one-fourth in this example) to form a thin part 26 consisting of a slope or a cross section.

The thin portion 26 can also form a concave notch 27 between each of the leveling rods 23 in a curved line.

The leveling rods 23 are made of a strong material such as steel and have a rod shape, and the appropriate number of base ends are buried in the pressure plate 22 to approximately the width of the pressure plate 22.The lumbosacral ends are fixed to the thin part of the pressure plate 22. They are formed in a comb-teeth shape by protruding parallel to each other from the slopes or cross sections of 26.

Next, to explain the operation of this device, the stopper bundle 21 is rotated to select either fixing or swinging of the adjustment rod 17, and the length of the adjustment rod 17 is adjusted to allow the leveling plate 13, the pressure plate 14 is tilted at a desired angle, and the sub-soil crusher 1 is placed in the paddy field.

When the substituting soil crusher 1 is driven forward to start the substituting work, the crushing body 11 digs into the soil and crushes the soil, and the crushed soil is rotated by the crushing body 11 and scatters backward. The ground leveling plate 13 hits the leveling plate 13 and becomes an instant embankment, but the leveling plate 13 moves forward.
It is pushed by the crushing device 14, and the muddy ground is leveled.

At this time, the leveling rod 23 guides and buries foreign matter 28 such as rice stumps and weeds scattered on the surface of the muddy water into the soil.
The thin wall portion 26 of No. 2 receives the muddy soil and muddy water and floats up and curves to some extent, thereby suppressing the muddy soil appropriately.

Further, if a concave notch 27 is provided in the thin wall portion 26 as shown in FIG. 3, it is particularly suitable for rice fields with a large amount of muddy water,
Because excess muddy water can be discharged more easily,
To prevent excessive water pressure from being applied to the suppression plate 22,
can be brought into close contact with the mud surface.

(g) Effects of the device Since this device has the above-mentioned configuration and function, the mud and muddy water pushed by the suppression device can flow out easily from between the leveling rods, and it also removes foreign objects such as stumps. It can be reliably embedded in muddy soil, and the muddy soil is well leveled, making it possible to perform very effective grading work.

In addition, since the structure is simple and strong, foreign matter does not become entangled with the suppression device, and the leveling effect of the land does not deteriorate.

Furthermore, since it is easy to manufacture and install, it saves a lot of labor and time and is economically effective.
