Description

[Detailed description of the invention] [Industrial application field] The present invention relates to the adjustment of ridges mζ;

[Conventional technology]

Conventionally, as this type of ridge leveling machine, as disclosed in Japanese Utility Model Application Publication No. 5790/1987 (a machine frame is connected to a two-travel body, an embankment rotor, a ridge leveling body, etc. are arranged on the machine frame, A method is known in which a back-and-forth flow is excited between a hydraulic power source and a hydraulic operating mechanism via a pressure oil connection pipe to cause the ridge straightening body to perform a reciprocating ridge beating motion.

[Problem that the invention seeks to solve]

However, in this structure, the pressure oil in the connecting pipe flows back and forth, and most of the return flow action is performed by the suction action, so a small amount of pressure in the connecting pipe flows back and forth. Oil leakage is also not allowed, and if oil leakage occurs, the return flow becomes inappropriate immediately, resulting in the inconvenience that □good ridge-leveling action of the ridge-leveling body cannot be obtained.

[Means for solving problems]

The purpose of the present invention is to solve these inconveniences, and its gist is to connect the machine frame to the traveling machine body, arrange the embankment rotor, ridge adjustment body, etc. on the narrow frame, and connect the hydraulic power source mechanism and hydraulic pressure. Pressure oil flows back and forth between the actuating mechanism and the connecting pipe to cause the ridge adjustment body to perform reciprocating ridge-beating motion. The ridge straightening machine is characterized by having two mechanisms installed at the highest part of the oil line.

[For production]

If flowing pressure oil leaks between the hydraulic power source mechanism and the hydraulic operating mechanism, the oil is replenished by the oil replenishment mechanism and air bubbles are removed.

In addition, a rear cover member CD is provided on the rear surface of the cover member (9) so that it can be adjusted up and down with bolts C and long holes C. A mud removal plate (24) is installed vertically.

In addition, in the hydraulic power source mechanism (c), the crank plate (5) is fixed to the rotating narrow 61 in the middle of the rear part of the machine frame (3), and the crank plate CI! ? ), the upper end of the connecting rod ri &
A drive piston (3 pistons) is vertically slidably inserted into the upper part of the drive cylinder cylinder 4, and a connecting pipe (to) is connected to the lower part of the drive cylinder cylinder (to). .

In addition, if the hydraulic actuation mechanism C34) is provided, the cylinder cylindrical member 0'7) and the center hole side are installed to be vertically movable via the mounting plate (G) provided on the vertical movement adjustment mechanism (T). It consists of a piston member 1 having
Four guide rollers KIJ are installed protruding from the guide roller (to).
4]) to make the guide member (4tJ freely slidable, and fix the Y1 stop (22 in the longitudinal section approximately) at the bottom of the guide member f41. A spring hook G13 is protruded from the mounting plate (G). The spring hook is constructed by hanging a return spring (T) between the bottle holder and the spring hook of the ribbed body frame (2).

This oil supply mechanism (four connecting pipes 133 as shown in Figure 3)
It is arranged in the upper "bent part", and the inside of the case body (46) is formed into two compartments with a partition plate (4'O), and the lower chamber (
Put oil (50) in 49, communicate with the lower chamber 4 to form two connection ports 6D, form a communication port 52 in the partition plate (4η), and install an opening/closing bolt (to) on the upper wall of the case body. and form an oil inlet l54), and connect a connecting pipe Q to the connecting port 6υ.
connecting the middle part of the partition plate (47) to form the partition plate (47) in the middle and height;
Air bubbles in the connecting pipe (G) are made to converge at the communication port (position 521).

Further, the ridge adjustment body (8) of the embodiment is formed in a cross-sectional shape, and the upper part of the ridge adjustment body (8) has a removable structure.
By removing 8a) from the base ridge adjustment body (8b), the ridge (4)
The size and shape of the upper surface of the
5) is a return spring.

In addition, a flexible loose box part 6E9 made of rubber, sponge, sheepskin, etc. is attached to the ridged surface of the ridge adjustment body (8).

Since this embodiment has the above configuration, the traveling body (1) is
4), the embankment rotor (5) rotates and heaps mud such as +41 WA onto the ridge, and the crank plate rotates due to the rotation of the rotating shaft (to), driving the drive piston G4. slides up and down, the oil in the drive cylinder cylinder c30) and the cylinder cylinder member (37) flows through the connecting pipe, and as a result, the ridge adjustment body (8) moves, The embankment is pounded and tightened using hydraulic pressure.

At this time, if the oil in the connecting pipe (to) leaks, air bubbles are generated in the connecting pipe (to), and these air bubbles are removed from the case body (4) of the oil supply mechanism 4.
6) When the images gather in the lower chamber 419, stop the machine and open the communication port 6a by turning the opening/closing bolt @.
The air bubbles in the lower chamber (4) rise into the upper chamber (c), and the oil in the upper chamber (4) rises into the lower chamber (491:).

As a result, air bubbles can be removed from the connecting pipe (to) and oil can be replenished, allowing the connecting pipe Q to remain full of oil, thus ensuring smooth and good flow of pressure oil within the connecting pipe. This allows the ridge adjustment body (8) to perform a good ridge beating operation.

In addition, as another embodiment, the embankment rotor may have a structure in which the rotational axis of the embankment rotor is perpendicular or oblique to the ridge creation direction.

〔Effect of the invention〕

As described above, in the present invention, when oil leaks in the connecting pipe, the oil can be replenished by the oil replenishment mechanism, and the connecting pipe can be maintained in a full state of oil, thereby allowing the pressure oil in the connecting pipe to flow smoothly and well. , the ridge-beating action of the ridge-leveling body can be performed well.

゛ , -・ ・In case of oil leakage (from 2), if air bubbles occur, install the oil system path that also serves as a bubble bleed at the highest part (2), which makes it easy to bleed air, and further prevents oil from flowing back in the oil system path. It becomes an excellent ridge leveling machine with good flow and reliable ridge pounding action.
