Description
Technical Field
The utility model relates to a ditching machine field specifically is a chain ditcher power transmission.
Background
The conventional chain ditcher power transmission device for a chain ditcher with an auxiliary tool for operation of a skid-steer loader is structurally characterized in that a bearing seat is sequentially provided with a double-hole check ring, "bearing 22210C", a driving shaft, "oil seal 60x80x 12" (pre-installed in a gland), the gland is installed on the bearing seat through a bolt and a check washer, a spacer, "bearing 7210C (external dimension 50x90x 20)", a retaining washer and a round nut M50x1.5. The bearing seat is fastened and installed on the motor connecting seat through a sunk screw. The motor connecting seat is arranged on a welding piece consisting of a supporting sleeve and a supporting plate through fasteners such as bolts and the like. The hydraulic motor is mounted on the motor connecting seat through fasteners such as bolts and the like. The right end of the driving shaft is connected and installed with the double key grooves in the hole of the coupler through double keys, and the spline hole at the other end of the coupler is connected with the spline shaft of the hydraulic motor. An oil cup M10x1 is arranged above the middle part of the motor connecting seat so as to be convenient for filling lubricating grease. And the cutter chain driving chain wheel is arranged at the left side of the driving shaft through double-key connection, and the soil separator synchronously and coaxially rotating with the driving shaft is connected with the driving shaft through two driving bolt fasteners. The power transmission device has the disadvantages of complex structure, high manufacturing process cost, low normal service life caused by small bearing 7210C (the outer dimension is 50x90x 20) bearing capacity and complex coupling stress, difficulty in fully filling lubricating grease due to the fact that the position of the oil cup M10x1 is far away from the bearing 22210C and the like.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide a chain type ditcher power transmission device, which reduces parts with higher precision, obviously reduces the matching surface with higher precision and obviously reduces the difficulty of process manufacturing.
The technical scheme of the utility model is that: a power transmission device of a chain type ditcher comprises a hydraulic motor, a motor seat flitch, an oil cup, a driving shaft, a cutter chain driving chain wheel, a bearing supporting seat and an oil duct steel pipe, wherein the bearing supporting seat, the oil duct steel pipe and the motor seat flitch are respectively welded with a supporting plate to form a combined piece, a double-hole check ring, a bearing and a gland with an oil seal are sequentially arranged in the bearing supporting seat and are arranged on the bearing supporting seat through bolts and a check washer, the driving shaft is arranged at the central part, the bearing, the double-hole check ring, a stop washer and a round nut are arranged at the right side part, a spline shaft of the hydraulic motor is inserted into a spline hole at the right end of the driving shaft and is tightly arranged on the motor seat flitch through bolts and a release washer, an O-shaped rubber sealing ring is arranged between the hydraulic motor and the motor seat flitch, the oil cup is arranged on the motor seat flitch above the hydraulic motor, the left side part of the driving shaft, and the cutter chain driving chain wheel are connected and arranged through double bonds, the soil separator which rotates synchronously and coaxially with the driving shaft is connected with the driving shaft through two driving bolt fasteners.
The utility model discloses a theory of operation is: the hydraulic motor is driven to rotate by hydraulic power provided by the skid-steer loader, and through the matching of a spline shaft of the hydraulic motor and an internal spline of a driving shaft, the hydraulic motor is coaxially and synchronously directly driven in the same direction, a cutter chain driving chain wheel for driving the working device is driven to rotate directionally (so that the cutter chain digs soil into a groove) and the soil divider rotates directionally, and meanwhile, soil piles on the ground for ditching operation are timely divided to one side of the groove.
The utility model has the advantages that: compare with a current chain ditcher power transmission, the utility model discloses the part of higher accuracy has been reduced to the fitting surface of higher accuracy also obviously reduces, is showing the degree of difficulty that has reduced the technology and has made.
