JP3049153U - Hydraulic motor-driven mower that can move logging - Google Patents

Abstract

(57) [Summary] (Corrected) [Problem] To provide a device that makes it easy and safe to cut down high places and depressions, and that can move cut and piled cuts without removing the present device. SOLUTION: A pressure oil is sent to a hydraulic motor 1 to rotate the hydraulic motor to rotate the chain tension adjusting pulley 2 and a shaft 3 for rotating the disk to transmit the rotation by driving the chain 5, and the sickle is generated by the centrifugal force generated in the disk. Blade 11 jumps out,
The cut and piled cut material is held by the curved band iron plate 6 fixed to the mower main body, and the cut material can be sandwiched, moved, and loaded by moving the curved band iron plate that is connected and driven. This device is mounted on the tip of a power shovel and near the tip, and can be operated from the driver's seat.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 In this invention, by rotating the hydraulic motor, the pulley for adjusting the chain tension and the disk shaft connected by the chain also rotate at the same time. This rotation generates a centrifugal force on the disk, causing the sickle-shaped blade to pop out.The curved cut-out plate is fixed to the rear of the mower and is connected to the curved iron plate by a hydraulic cylinder. It moves while being sandwiched between striped steel plates.

[0002]

[Prior art]

 Conventionally, there have been fixed disc-shaped saw blades, fixed bar-shaped blades, centrifugal plate-shaped blades, and those capable of moving an object as a single unit.

[0003]

[Issues to be solved by the invention]

 (A) Fixed disk-shaped saw blades and fixed bar-shaped blades are very dangerous because if the blade hits a hard object such as a stump or pebble, the impact may damage the device body or cause the broken blade to fly. Met. (B) The plate-shaped two-blade protruding due to the centrifugal force was made smaller, so that it was difficult to work on slopes and was only available on flat ground. With a plate-shaped two-blade, cutting the bamboo or tree was difficult due to the small shape of the blade. (C) The machines used to cut and move the felled material were only single items, and when moving a large volume of felled material or loading them into a car, they required a great deal of labor and a large number of people. When using a machine that moves logging, there is a drawback in that it takes time to replace the logging machine after removing the logging machine, and then replacing it, which reduces the logging capacity.

[0004]

[Problem to solve the problem]

 This will now be described with reference to the drawings. (1) Pressurized oil is sent to the hydraulic motor (1) to rotate the hydraulic motor (1). (2) The rotational force of the hydraulic motor (1) is transmitted to the pulley (2) for adjusting the chain tension and the shaft (3) for rotating the disk (4) by connecting the chain (5). (3) The rotation of the disk (4) generates centrifugal force, and the sickle-shaped blade (11) attached to the disk (4) pops out. (4) Curved strip-shaped iron plate fixed to the rear part of the body of the mower, and the mower body is attached to the tip of the arm of the power shovel. When) is operated, the mower itself moves according to the amount of movement of the cylinder. Due to this movement, the felled material is held by the curved iron plate (6) fixed to the rear of the mower body, and the hydraulic cylinder (8) attached to the bracket (7) near the tip of the arm of the power shovel. By actuating, the curved strip-shaped iron plate (9) that is connected and driven to the hydraulic cylinder (8) is operated. With this operation, the felled material is pinched and moved by moving the curved banded iron plate (9) connected and driven to the curved banded iron plate (6) fixed to the rear part of the mower main body.

[0005]

[Embodiment of the invention]

 With the above configuration, if a rotational force is applied to the hydraulic motor, a sickle-shaped blade protrudes from the disk, cutting weeds, bamboos, and trees, and moving the cut logging by operating the hydraulic cylinder. . This device is installed on the extremity of the excavator arm and near the extremity and can be operated from the driver's seat.

[0006]

[Effect of the invention]

 This model has the structure described above.When this is used, it can be attached to the extremity of the excavator arm and near the extremity. Easy. Since the sickle-shaped blade is not fixed, even if it hits an object that cannot be cut, it escapes to the inside of the disk, so the blade does not break and fly. Since the blade has a sickle shape, the cutting time is long and the cutting efficiency is good. Even if a shock is applied to the disk, the relief valve is installed inside the hydraulic motor, so if a reverse pressure exceeding the set pressure is generated, pressure oil will not be sent to the hydraulic motor and pressure will be sent directly from the relief valve to the return circuit. To release oil, the rotational force on the disk is stopped, and there is little damage to the equipment. It is possible to move and load the harvested material while cutting without removing the equipment.
