Abstract

The invention relates to a shearing device for a reverse circulating system of a saw slotting machine. The shearing device comprises an upper motor, wherein a crank is arranged below the motor and is connected to a saw cutter frame through a connecting rod; a cutting board is arranged below the saw cutter frame; a sliding block is arranged on the saw cutter frame; the saw cutter frame is suspended on a support arm rod by the sliding block; the motor is connected to the upper end of the support arm rod; a reverse circulating pump sucking pipe is fixed at the lower end of the support arm rod; an annular tube is arranged at the lower end of the reverse circulating pump sucking pipe; several paths of trapezoidal tool sections A are arranged in the annular tube; a rectangular outer frame is arranged at the lower end of the annular tube; the right end of the rectangular outer frame is fixed on the saw cutter frame; several paths of trapezoidal tool sections B are arranged in the rectangular outer frame; the sections of both the trapezoidal tool sections A and the trapezoidal tool sections B take the shapes of trapezoids; blades are arranged at two base angles of each trapezoid; and the upper sections of the trapezoidal tool sections B slide below the lower sections of the trapezoidal tool sections A for shearing. The shearing device for the reverse circulating system of the saw slotting machine is arranged on a sucking port of a reverse circulating pump; and strip-shaped objects such as tree roots and weeds which are sucked into the sucking port are sheared by using relative motion between the sucking port and the lower end of the saw cutter frame as power, and thus the sheared objects are conveniently discharged from the reverse circulating pump.

Description

The anti-circulating system shear of The trench saw
One, technical field
The present invention relates to a kind of anti-circulating system shear, the anti-circulating system shear of particularly a kind of The trench saw.
Two, background technology:
The operating principle of The trench saw is: the motor-driven crank rotates; Crank is sawed knife rest through the connecting rod push-and-pull in rotation process; The saw knife rest reciprocatingly slides through the slide block orientation on support arm on the saw knife rest; Knife plate on the saw knife rest stirs into mud with geology soil, and mud is made groove by inverse circulation pump outward through the suction inlet suction back drain tank of The trench saw lower end.Inverse circulation pump often runs into long strip shape objects such as tree root, weeds in suction mud process, inverse circulation pump is twined, blocks.
Three, summary of the invention:
The present invention has remedied the shortcoming of above The trench saw, provides a kind of The trench saw anti-circulating system shear.
The present invention realizes through following technical scheme:
The anti-circulating system shear of a kind of The trench saw comprises the motor on top, and motor has crank; Crank is connected in the saw knife rest through connecting rod, and the saw knife rest has knife plate, and the saw knife rest is provided with slide block; Slide block will be sawed knife rest and be hung on the support arm, and the support arm upper end is connected with motor, and the lower end is fixed with the inverse circulation pump suction pipe; The suction pipe lower end is provided with ring pipe, is provided with the trapezoidal tool section A in several roads in the ring pipe, and the rectangle housing places the lower end of ring pipe; Rectangle housing right-hand member is fixed on the saw knife rest, is provided with the trapezoidal tool section B in several roads in the rectangle housing, and trapezoidal tool section A, trapezoidal tool section B cross section are trapezoidal; Two trapezoidal base angles are provided with blade, and the upper edge of trapezoidal tool section B is sheared in the following tangent plane lower slider of trapezoidal tool section A.
The present invention has following characteristics:
The anti-circulating system shear of The trench saw is arranged on the inverse circulation pump suction inlet, utilizes the suction inlet and the relative motion of the lower end of saw knife rest to be power, and long strip shape objects such as the tree root that sucks suction inlet, weeds are sheared, and makes things convenient for inverse circulation pump to discharge smoothly.
Four, description of drawings:
Below in conjunction with accompanying drawing the present invention is further described:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is A-A, B-B view.
Fig. 3 is C-C, D-D view.
Among the figure: 1, motor, 2, crank, 3, slide block, 4, the saw knife rest, 5, knife plate; 6, support arm, 7, the inverse circulation pump suction pipe, 8, ring pipe, 9, the rectangle housing, 10, trapezoidal tool section A; 11, trapezoidal tool section B, 12, blade, 13, tangent plane down, 14, upper edge.
Five, the specific embodiment:
Accompanying drawing is a kind of specific embodiment of the present invention, and this embodiment comprises the motor 1 on top, and motor has crank 2; Crank is connected in saw knife rest 4 through connecting rod, and the saw knife rest has knife plate 5, and the saw knife rest is provided with slide block 3; Slide block will be sawed knife rest and be hung on the support arm 6, and the support arm upper end is connected with motor, and the lower end is fixed with inverse circulation pump suction pipe 7; The suction pipe lower end is provided with ring pipe 8, is provided with the trapezoidal tool section A10 in several roads in the ring pipe, and rectangle housing 9 places the lower end of ring pipe 8; Rectangle housing right-hand member is fixed on the saw knife rest 4, is provided with the trapezoidal tool section B11 in several roads in the rectangle housing, and trapezoidal tool section A10, trapezoidal tool section B11 cross section are trapezoidal; Two trapezoidal base angles are provided with blade 12, and the upper edge 14 of trapezoidal tool section B is sheared in following tangent plane 13 lower slider of trapezoidal tool section A.
When the present invention works; Motor drives the saw knife rest through crank, connecting rod and moves back and forth; The rectangle housing and the trapezoidal tool section B that are fixed on saw knife rest lower end also move back and forth, so trapezoidal tool section A and trapezoidal tool section B will pass through the long strip shape object of suction inlet and shear in relative motion.
