Abstract

A wheel-type ditcher relates to the earthwork operation machinery, and is characterized in that two sides of a machine base are provided with sliding sleeves, wherein the sliding sleeves are sleeved on guide pipes which are added on two sides of a machine frame in a moveable matching mode, the structure of the machine frame is that the lower ends of the two vertical guide pipes are transversely sleeved with a wheel shaft, two ends of the wheel shaft are sleeved with walking wheels, a framework shaped like the Chinese character 'hui' is further fixed on the lower end of the machine frame, a hollow drill bit threads through the framework, the machine frame is provided with a machine base lifting device, the lifting device comprises two guide pipes whose upper sides are respectively fixed with riser plates, a chain wheel spindle is sleeved in the central holes of the two riser plates in a movable matching mode, a drive sprocket wheel is fixed on the middle portion of the chain wheel spindle, a hand crack is fixed on one end of the chain wheel spindle, the middle portion of the wheel spindle is sleeved with a driven sprocket wheel, two ends of a chain are fixed on a locking seat on the bottom of the machine base after the chain encloses the two sprocket wheels, and the machine frame is further fixed with a machine base locking device. The wheel-type ditcher has the advantages that as the machine base is sleeved on the wheel-type machine frame, the wheel-type ditcher can be pushed with less labor in moving, simultaneously, the wheel-type pushing structure design provides essential conditions for increasing power of the ditcher, which realizes the operation of digging big holes.

Description

The trenching wheel machine

Technical field:

The utility model relates to earthwork machine, is specially adapted to the operation of digging pit.

Background technology:

Existing trench excavator is made up of motor, reducer, screw type bit, support, motor is generally gasoline engine and is installed on the support and is connected with reducer, reducer output shaft is connected with drill bit, support is provided with hand-held, motor drives reducer, drill bit rotation successively, the operator is then grabbing hand-held handle and is opening throttle, drill bit under motor and reducer action of gravity or operator's application of force under lower compression, pierce ground and implement to dig pit.

There is following defective in this structure, and the one, the preceding operator of complete machine construction need firmly lift machine and put in place, and the 2nd, manpower is lifted machine causes complete machine weight limited by manpower, want big drill bit and dig hollow place, complete machine is too heavy can't operation, thereby restriction complete machine power, can't implement the big drill bit operation of big machine.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned defective, and a kind of trenching wheel machine is provided.

Scheme of the present utility model is: comprise motor, reducer, drill bit, support, it is characterized in that the support both sides are provided with slip cap, this slip cap is enclosed within on the guide rail pipe of the frame both sides of setting up movingly; Rack construction is that vertical two horizontal fits in guide rail pipe lower end wheel shaft, wheel shaft two ends fit road wheel, and the frame lower end also is fixed with three-back-shaped framework, and this framework hollow space satisfies drill bit and passes, and base of frame four angles extension down are fixed with bitch; Frame is provided with baseplate hoisting device, lifting gear is that two guide rail pipe tops are fixed with seat board respectively, two seat board medium pores are with sprocket shaft movingly, the sprocket shaft middle part is fixed with drive sprocket, sprocket shaft one end is fixed with hand crank, a cover unification movingly driven sprocket in wheel shaft middle part has a chain its two ends behind two sprocket wheels to be fixed on the locking seat of support bottom; Also be fixed with the support locking device on the frame.

Advantage of the present utility model is: support is linked on the wheel open frame, can carry out laborsavingly when mobile, and simultaneously wheeled implementation structure design strengthens trench excavator power primary condition is provided, and has realized digging the hollow place operation.

Fig. 2 is a support locking device structure schematic diagram.

The specific embodiment:

Structure of the present utility model comprises motor (6), reducer, drill bit (10), support (9), it is characterized in that support (9) both sides are provided with slip cap, and this slip cap is enclosed within on the guide rail pipe (3) of frame (1) both sides of setting up movingly; Frame (1) structure is that the horizontal fit in vertical two guide rail pipes (3) lower end wheel shaft, wheel shaft two ends fit road wheels (5), frame (1) lower end also is fixed with three-back-shaped framework (11), this framework (11) hollow space satisfies drill bit (10) and passes, and framework (11) bottom four angles extension down are fixed with bitch; Frame (1) is provided with support (9) lifting gear, lifting gear is that two guide rail pipes (3) top is fixed with seat board (8) respectively, two seat boards (8) medium pore is with sprocket shaft (2) movingly, sprocket shaft (2) middle part is fixed with drive sprocket, sprocket shaft (2) one ends are fixed with hand crank (7), a cover unification movingly driven sprocket in wheel shaft middle part has a chain (4) its two ends behind two sprocket wheels to be fixed on the locking seat of support (9) bottom; Also be fixed with support (9) locking device on the frame (1).

Support (9) locking device is to be fixed with locking cover (14) on a side rails pipe (3) the top seat board (8), be sheathed with lock shaft (13) in the locking cover (14), lock shaft (13) the rear side fixedly locked cap of bearing pin (17) (16), these lock shaft both ends are linked in the grooves on two sides (15) of locking cover (14) upper edge after protruding locking cap (16), periphery, lock shaft (13) middle part is with the compression spring, this compression spring is pressed between lock shaft (13) convex edge, front side and locking cover (14) the top spacing collar, sprocket shaft (2) one sides are fixed with toothed wheel (12) corresponding to lock shaft (13) orientation, and lock shaft (13) front end is provided with the rectangular boss less than toothed wheel (12) space width.

During the complete machine walking, lock shaft (13) rectangular boss of support (9) locking device is inserted in toothed wheel (12) between cog location, makes support (9) be in positioning states.

When digging pit, hold up frame (1), frame (1) bottom bitch and road wheel (5) four point locations, the locking cap (16) of then outwards pulling out toothed wheel (12) locking device makes bearing pin (17) cover (14) groove (15) that goes out of lock, revolve again and turn 90 degrees screens on locking cover (14) end face, make lock shaft (13) rectangular boss break away from toothed wheel (12) tooth, then support (9) is in free state.

Dig pit finish after, shake the hand crank (7) of lifting gear, sprocket rotation, because chain (4) two ends are positioned on the support (9), then support (9) rises overally, and rises and to put back toothed wheel (12) in place with the locking device locking, and then complete machine is feasible walks to enter the next one operation of digging pit.
