Abstract
The utility model discloses a multifunctional ditching and pit-digging device which comprises a fixing frame, a power shaft driven by a power source is arranged on the fixing frame, and a drill bit body or mill head body is arranged on the power shaft. The utility model has the advantages that the power shaft driven by the power source is arranged on the fixing frame, the drill bit body or mill head body is arranged on the power shaft, so that the power shaft drives the drill bit body or the mill head body to rotate; and the drill bit body or the mill head body is movably connected with the power shaft, and can be arbitrarily replaced as required. The utility model can be connected with the actuating arm of the small and medium-sized excavator, and also can be driven by the small machinery to work such as tractors, small loading machines, and the like; and meanwhile, the utility model can achieve the multifunctional purpose by replacing the drill bit body or the mill head body (the pits with different sizes can be dug by using the drill heads with different sizes, and the groove in width of 200mm and depth of 1m can be dug by replacing the mill head), and has simple a structure and convenient use.
Description
Technical field
The utility model relates to excavating gear, especially relates to the multi-functional trench digging device of digging pit.
Background technology
Ditching when tree well or laying pipe cable are dug in afforestation of city at present, all be manually to excavate with instruments such as spades, because the condition restriction of hand digging itself, very narrow ditch also needs to dig very wide, so just need and operating efficiency be reduced, destroy the road surface, and then influence normal road traffic with great amount of manpower.
The utility model content
The purpose of this utility model be to provide a kind of fast, efficient and can conveniently adjust ditching or the multi-functional trench digging of the width of the digging pit device of digging pit.
For achieving the above object, the utility model can be taked following technical proposals:
The multi-functional trench digging described in the utility model device of digging pit comprises fixed mount, and described fixed mount is provided with the line shaft by drive power source, and described line shaft is provided with bit body or body of milling head.
Flexibly connect between described bit body or body of milling head and the line shaft, according to using replaceable corresponding bit body of needs or body of milling head.
Described bit body is for being arranged on helical blade and the drill bit on the described line shaft from top to bottom; The setting of drill bit is the position of positioning pit accurately.
Advantage of the present utility model is described fixed mount is provided with line shaft by drive power source, and described line shaft is provided with bit body or body of milling head, makes line shaft drive bit body or body of milling head rotates;
To flexibly connect between described bit body or body of milling head and the line shaft, can arbitrarily change bit body or body of milling head as required; Described bit body makes the operation of digging pit more accurate for being arranged on helical blade and the drill bit on the described line shaft from top to bottom; While helical blade low cost of manufacture and easy to process.During ditching, bit body is replaced by body of milling head, the multi-functional trench digging design factors of digging pit is tilted,, just can dig out the accurate ditch of width by using suitable milling head.The utility model can be connected with the working arm of medium and small excavator, also can use small-sized machine such as tractor, and small sized loader drives its work; Just can realize a tractor serves several purposes by changing bit body or body of milling head (drill bit that varies in size can dig the hole that varies in size, and changes milling head and can excavate 1 meter dark groove of 200 mm wides), and simple in structure, easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, the multi-functional trench digging described in the utility model device of digging pit, comprise by bearing pin and the joining fixed mount 1 of excavator power wall, be set with helical blade 3, drill bit 4 on the line shaft 2 of hydraulic electric motor 5 at hydraulic electric motor 5 from top to bottom and fix being fixed with on the fixed mount 1 by bearing pin; With the operation of can digging pit that is connected with the vehicle-mounted pumping plant of excavator of the liquid inlet and outlet 6,7 of hydraulic electric motor 5.When needing ditching, bit body is taken off the body of milling head of loading onto and needing the ditching width to adapt, body of milling head axis and ground are tilted, can dig out the groove that needs width by the rotation and the moving of excavator of body of milling head.
