Description

[Detailed explanation of the invention] (Field of industrial application) This invention plows the soil in the field before sowing,
This invention relates to a cage-type land leveling roller that crushes the surface of the tilled soil into fine particles, leveling it, and compacting it.

(Prior art) In general, this type of cage-type land leveling roller plows the soil in a field with a plow or the like, crushes the surface part into fine particles with a soil crushing harrow, and then is towed to level and level the topsoil. It is something to suppress.

For this reason, in order to improve leveling and compaction effects and to prevent soil clods from entering the roller, cage-type soil leveling rollers are constructed by placing steel bars horizontally across both side plates at appropriate intervals in the circumferential direction and at an angle. It was formed by hanging.

(Problem to be solved by the invention) However, although large clods do not easily enter the cage-type land leveling roller, small clods do, and these clods grow snowball-like while being towed and leveling the land, and eventually The disadvantage was that the gaps between the steel bars were clogged with these clods, making it impossible to level and compact them as desired.

The present invention has been developed in view of the above-mentioned circumstances, and its purpose is to crush the soil clods inside the cage-type soil leveling roller and discharge them to the outside of the soil leveling roller.

(Means for solving the problem) This invention is intended to achieve the above-mentioned object, and the cage-type leveling roller is made of steel bars placed at appropriate intervals in the circumferential direction across both side plates. These steel bars are suspended horizontally, and are equipped with earth crushing members with a chain hanging from the side plates on both sides with the center slackened inside the steel bars.

(Function) According to the squirrel cage type ground leveling roller of this invention, the ground leveling is carried out by the earth crushing member of the chain which is stretched inside the steel bars of the steel bars suspended at appropriate intervals in the circumferential direction of both side plates. As the roller rotates,
It breaks up the soil clods that have gotten into the soil leveling roller and discharges them out of the soil leveling roller, allowing the soil leveling roller to function normally.

(Example) An embodiment of the present invention will be described based on the drawings.

Fig. 1 shows a cage-type soil leveling roller to which an embodiment of this invention is applied. :Equipped behind the power harrow).

Fig. 2 shows a state in which a cage-type soil leveling roller A is rotatably installed at the rear of a drive-type earth crusher B via a mounting arm. A large number of vertical shaft rotating screw blades c having spiral vertical blades b are equipped in parallel, and the power transmission mechanism and transmission E mounted on the machine frame a are
By connecting to the power source of tractor D via PTOC, each screw blade c moves through the soil while rotating, crushing the top soil finely in the upper part and coarsely crushing the lower part without turning over the soil. .

The cage-type soil leveling roller A finely cuts the surface layer of the soil crushed by the drive-type soil crusher B by rotating under the traction of the tractor D in order to condition the cultivated soil to be suitable for crop germination, rooting, and growth. It is crushed into particles, leveled and compacted to create soil with excellent air permeability and water permeability.

The above-mentioned squirrel-type soil leveling roller A is formed by horizontally suspending steel bars 3 in parallel at appropriate intervals in the circumferential direction across the side panels 2 on both sides, and with a soil crushing member installed inside the soil leveling roller A. Equip 1.

The soil crushing member 1 is used to finely crush the large soil clod that has entered the soil leveling roller A, and also to crush the soil clod that fills the gaps between the steel bars. A chain 4 is stretched between freely provided hooks 2a and 2b with the center part slackened.

As the soil leveling roller A is rotated by the tractor D, the chain 4 is constantly swung, and the soil clods that have entered the soil leveling roller A are broken into small pieces and discharged to the outside of the soil leveling roller A.

In addition, the crushing member 1 is not limited to the chain 4 described above,
Insert into the soil leveling roller A something that can freely rotate and move within the soil leveling roller A as it rotates to break up the clods of soil inside the leveling roller A, such as a spherical iron lump or a steel bar of an appropriate length. This is also optional.

(Effects of the invention) Since the present invention has the above-mentioned configuration, during land leveling work, it is possible to break up large clods of soil that have entered the land leveling roller into small pieces and discharge them to the outside of the land leveling roller, thereby stabilizing the land leveling roller. be able to perform sufficient leveling and compaction work.
