Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ridge beating device in a ridge shaping machine that creates ridges.

[Conventional technology]

Conventionally, this type of ridge pounding device was manufactured by Jikosho.
As disclosed in Publication No. 57-10483, etc., a traveling machine, an earth embankment rotor, a ridge pounding plate, etc. are installed, and the mud at the edge of the ridge is heaped up onto the ridge with the earth embankment rotor and compacted by pounding with the ridge pounding plate. It is structured in a ridged manner.

[Problems to be solved by the invention] However, the ridge beating mechanism of the ridge beating board described above uses a lever crank mechanism to repeatedly raise and lower the ridge beating body, and in order to increase the ridge striking force, the lever crank must be made larger. Not only that, but it can also cause inconveniences such as vibration and noise.

For this reason, the applicant also proposed the adoption of a hydraulic mechanism instead of the lever crank mechanism (Utility Model No. 58-167503
However, when a hydraulic mechanism is adopted, a drive cylinder mechanism that pumps oil and an actuation cylinder mechanism that raises and lowers the ridge beating body are installed together, and a piston drive mechanism forces the oil from the drive cylinder mechanism to the actuation cylinder mechanism. However, it is desirable that the ridge beating body is moved up and down by an actuating cylinder mechanism, but the driving cylinder mechanism is provided above the piston drive mechanism, and the ridge beating body is connected to the piston member of the actuating cylinder mechanism to repeat the ridge beating operation. In both cylinders, oil leaks through the piston rod, and oil leakage becomes even worse in the ridge tapping device that continuously applies ridge tapping action accompanied by intense vibration for a long time. There is a drawback that the power is poor.

[Means for solving problems]

The present invention is intended to solve these drawbacks, and its structure will be detailed as follows with reference to the accompanying drawings.

Traveling machine body 1, machine frame 2, rotating rotor 8, ridge beating body 3
0 etc., the ridge leveling machine mounds soil on a ridge 7 with a rotating rotor 8 and compacts it by pounding it with a ridge pounder 30, which includes a drive cylinder mechanism 10 that pumps a working fluid 38 to the machine frame 2, and a ridge pounder. A working cylinder mechanism 20 is provided to raise and lower the working cylinder mechanism 20.
A pump chamber RO is formed at the lower side of the cylinder cylinder member 21 , and the pump chamber RO and the drive cylinder mechanism 10 are communicated with each other through the communication hole 22 of the piston member 23 and the communication pipe 37 , and the piston member of the actuation cylinder mechanism 20 is connected to the drive cylinder mechanism 10 . 23 and attach the cylinder member 21 to the mounting member 2.
5, the cylinder member 21 is provided with a ridge beating body 30.

[Effect]

The traveling machine travels along the ridge, the rotating rotor heaps up the mud near the ridge onto the ridge, the drive cylinder mechanism pumps working fluid to the actuating cylinder mechanism, and the ridge pounder moves up and down in a reciprocating manner to pound the embankment. By pounding it with your body, you will gradually create new ridges on top of the old ridges.

〔Example〕

1 to 3 show a preferred first embodiment to which the present invention is applied, in which a traveling machine body 1 (tractor)
The machine frame 2 is vertically movably connected by a three-point link type coupling mechanism 3, and a rotating main shaft 6 connected to the power take-off shaft 4 of the traveling machine body 1 by a universal joint 5 is horizontally mounted on the machine frame 2. A rotating rotor 8 is horizontally mounted in the ridge forming direction at a position on the ridge 7 side of the machine frame 2, and is rotated by a main shaft 6 and a chain mechanism 9 so as to heap mud into the ridge 7.

In the drive cylinder mechanism 10 of this embodiment, a main shaft 6 and a drive shaft 12 rotated by a chain mechanism 11 are horizontally mounted on the upper part of the machine frame 2, and a crank member 13 is fixed to the rear of the drive shaft 12. Crank member 1
3 and the piston member 14 are connected by a connecting rod 15, and a support rod 17 is suspended from the center of the bottom surface of the cylinder member 16, and the support rod 17 is attached to the mounting plate 18 of the machine frame 2 by a nut 18a. The figure shows a case in which the cylinder tube member 16 is loosely inserted in the piston member 14, and the cylinder tube member 16 is provided so as to be able to escape freely in the moving direction of the piston member 14, and a support spring 19 is interposed between the mounting plate 18 and the bottom surface of the cylinder tube member 16. .

Further, the operating cylinder mechanism 20 includes a cylinder tube member 21 and a piston member 23 having a communication hole 22, and a mounting member 25 is fixed with bolts 26 to a rear position of the rotor cover 24 on the ridge side of the machine frame 2.
The piston member 23 is attached to the mounting member 25 by the fixing member 27.
Support and fix the cylinder member 2 as shown in Figure 3.
A square pipe-shaped guide member 28 is fixed to the outer surface of 1,
Four guide rollers 29 are provided protruding from the mounting member 25,
A guide member 28 is slidably provided by a guide roller 29, and a ridge beating body 30 having a substantially square shape in longitudinal section is fixed to the lower part of the guide member 28.

Further, 31 is a return/return mechanism, and the mounting member 2
A spring hanging pin 32 is provided protruding from the spring hanging pin 3.
2 and a spring hanging piece 33 of the ridge beating body 30, a return spring 34 is suspended.

In addition, in this embodiment, the connection port 35 of the cylinder cylinder member 16 of the drive cylinder mechanism 10 and the communication hole 22 of the piston member 23 of the actuation cylinder mechanism 20 are connected to each other.
The connecting port 35 is connected through a communication pipe 37, and a working fluid 38, in this case oil, is sealed inside.

39 is a lubricant such as rubber, sponge, leather, hair, etc.
40 is a piston drive mechanism.

Since this embodiment has the above configuration, when the traveling body 1 travels along the ridge 7 and the rotating rotor 8 is rotated via the power take-off shaft 4, the main shaft 6, etc., mud is scraped up onto the ridge 7. It will be filled with earth. On the other hand, due to the rotation of the drive shaft 12 of the drive cylinder mechanism 10, the piston member 14 reciprocates within the cylinder cylinder member 16 due to the action of the crank member 13 and the connecting rod 15.
4 moves downward, the working fluid 38 flows into the cylinder tube member 21 through the communication pipe 37 and the communication hole 22 due to the discharge action of the piston member 14, and the cylinder tube member 21 flows into the cylinder tube member 21 due to the action of the guide roller 29. , overcomes the return spring 34 of the return/return mechanism 31 and makes a protruding action, and the ridge beating body 30 protrudes toward the ridge, hits and compacts the ridge 7, and then the piston member 1
4 moves upward, due to the spring pressure of the return spring 34 and/or the suction action of the piston member 14,
The working fluid 38 inside the cylinder tube member 16 is connected to the communication hole 2
2. The working fluid 38 flows into the cylinder member 16 through the communicating pipe 37, and due to the reciprocating movement of the piston member 14, the working fluid 38 flows between the driving cylinder mechanism 10 and the working cylinder mechanism 20 through the communicating pipe 37. The ridge beating body 30 moves up and down repeatedly due to the inflow and outflow action of the working fluid 38 to perform the ridge beating movement, and the return and return mechanism 31 smoothly moves the ridge beating body 30 back, The ridge 7 can be struck and tightened with a smooth beating motion.

During this ridge-pounding operation, if a high load is applied to the ridge-pounding body 30 due to embankment conditions, such as the height of the embankment and the hardness or softness of the embankment, making it difficult to project the ridge-pounding body 30, the cylinder cylinder of the working fluid 38 It becomes difficult to discharge to the member 21, and the protruding operation of the piston member 14 becomes difficult, but at this time, the cylinder member 16 escapes against the support spring 19 in the piston movement direction,
The protruding and retracting movement of the piston member 14 can be performed smoothly,
The tapping force of the ridge beating body 30 can also be adjusted by the spring pressure of the support spring 19, and a more accurate ridge tapping action can be obtained.

In addition, since a hydraulic pump, flow path switching valve, etc. are not used, it is possible to reduce costs, and the difficulty of high-speed switching that occurs when using a flow path switching valve is eliminated, and the ridge beating body 30 can be moved at high speed. It can make reciprocating movements, and it can make small reciprocating movements, allowing for good ridge tapping.

Furthermore, in the case of this embodiment, since it is a combination of a mechanical structure and a hydraulic structure, and both mechanisms 10 and 20 are communicated with each other through a communication pipe 37, the arrangement of each component, especially the actuating cylinder mechanism 20, can be flexible. Therefore, the ridge beating body 30 can be easily placed at an appropriate position.

In the above embodiments, the structure of the rotating rotor 8 is designed with appropriate changes such as arranging the rotational axis of the rotating rotor 8 in a direction intersecting the ridge forming direction.

Further, it is also possible to arrange a plurality of ridge beating bodies 30 to form a structure with multiple stages of beating.

The drawings show a case where the pump chamber A on the drive cylinder mechanism 10 side is also provided on the lower side of the cylinder cylinder member 16 to prevent oil leakage.

[Effect of idea]

As described above, the present invention forms a pump chamber in the lower part of the cylinder member of the actuating cylinder mechanism, communicates this pump chamber and the driving cylinder mechanism through the communication hole of the piston member and the communication pipe, and connects the actuating cylinder mechanism with the pump chamber. The piston member is fixed and the cylinder member is provided so as to be able to move up and down with respect to the mounting member.Since the cylinder member is provided with a ridged body, the working fluid pumped by the drive cylinder mechanism is actuated through the communication hole of the piston member. The piston member is introduced into the pump chamber provided at the lower side of the cylinder member of the cylinder mechanism, and the piston member is fixed to the mounting part, but the cylinder member with the ridge-beating body is connected to the inflow and return flow of the working fluid. It will move up and down depending on the action.

Therefore, the pump chamber on the operating cylinder mechanism side is not of the type in which the piston rod is fitted into the bottom wall, and the bottom of the cylinder cylinder member is in a sealed state, so there is no fear of oil leakage.

In this way, it is a high-performance ridge pounding device that uses a hydraulic mechanism to perform fast ridge pounding operations with little vibration, yet there is no oil leakage through the piston rod, and it can be used continuously for long periods of time. This is an excellent ridge-pounding device for a ridge-setting machine that always performs the ridge-pounding operation accurately.
