Description

Chain bucket excavator

The utility model relates to and a kind ofly being made of digging arm and jacking system etc., and being used to excavate pond, fish pond and river is the main chain bucket excavator that excavates object with sandy soil.

Deposit farming and go out infrastructure especially in the water conservancy construction process, often need to drop into large quantities of human and material resources and excavate pond, fish pond and river.Adopt mechanized can save the man power and material in large quantities.Existing excavation machinery mainly contains various ways such as crowd shovel, backhoe, pulling scraper and grab bucket, and crowd shovel and backhoe excavating machinery serve as to excavate object with loose soil, sandstone generally, are applicable to excavating of bulk cargo.And existing other excavation machineries mainly are suitable for excavating of solid piece formula material, as occasions such as the exploitation of mountain stone, coal minings.Existing these excavation machinery common configuration all compare heavy, own wt is bigger, using and move quite not make, often need to be equipped with powerful mechanically moving or be equipped with truck, is the excavation machinery of excavating object with friable soil and sandstone especially, in the area, low-level bog or when using rainy season, owing to reasons such as structure heavinesses, often can't construct, and because its complex structure, be difficult for grasping immediately so use and operate, generally will after special training, could use.And existing excavation machinery is difficult to popularize in rural area and self-employed worker owing to its complex structure causes its cost height, thereby is unfavorable for that farming goes out the mechanization of infrastructure.

Goal of the invention of the present utility model is to overcome existing excavation machinery and is difficult for the shortcoming promoted the use of in the self-employed worker of rural area, seek to manufacture and design a kind of simple in structure, power is little, use easy to operate, price is low, and is in light weight and what be convenient to move is the chain bucket excavator of excavating object with friable soil and sandstone.

In order to realize the foregoing invention purpose, the utility model adopts the conventional mechanical processing technology to make to one-tenth, and complete machine, drives axle system and gear and rotates, thereby order about digging arm work as power with diesel engine.The rotation of axle system also drives drive shaft turns, thereby makes conveyor running.Manpower pedal's sprocket wheel orbits chassis, finishes complete machine moving and mining process on vertical and horizontal direction.The utility model complete machine is made of digging arm, conveying device, power and transmission mechanism, digging arm lifting gear, frame and walking system six parts.Anistree sprocket wheel is coaxial with its abutment shaft, and driving-chain both sides uniformly-spaced symmetry are shaped on sprocket and chain bucket respectively, forms strand and drives, the effect that twin-bucket is excavated.Be shaped on tensioning spring in the middle of last armed lever and the lower arm rod, the end of digging arm connects with movable guard bar, the upper arm boom end not with anistree sprocket coaxiality, form near with this moveable hinge connection.

The utility model compared with prior art has simple in structure, and is in light weight, applied widely, uses easy to maintenancely, is easy to move, and price is low, less energy consumption, efficient advantages of higher.

Fig. 2 is the digging arm structure front elevational schematic of the utility model.

Fig. 3 is the digging arm structure schematic top plan view of the utility model.

Each several part was constructed as follows when the utility model was implemented: digging arm (1) by anistree sprocket wheel (25), go up armed lever (26), tensioning spring (27), lower arm rod (28), sprocket (29), driving-chain (30), chain bucket (31), sliding way (32), glide path (35), end frame (33), end wheel (34), carriage (36) and form, with the effect of excavating of realization bulk material; Conveying device is made up of conveyer belt (12) and driven roller (13), is excavated the conveying effect of material to finish; Power and transmission mechanism are made up of diesel engine (8), axle system (7), axle system (21) and axle system (22), transmit effect to realize power; The pick arm elevator apparatus is made up of moving counterweight (10), pulley (14), pulley (15), movable pulley (20), manual winding up roller (3), pulley (19), pulley (16) and movable guard bar (2), with the space lifting effect of common realization digging arm (1), reach and regulate the purpose of excavating the degree of depth; Frame and walking system are made up of underframe (11), fixed triangle frame (23), ladder frame (9), steel cable (14), (17), (18) and chassis (6), track (5), pedal sprocket wheel (4), to finish moving and orientation adjusting effect of complete machine.

The anistree sprocket wheel of making after forging and heat treatment (25) has higher scuff resistance, the axle system (22) that it docks with it is coaxial, it is the drive sprocket of digging arm (1), drive (30) both sides uniformly-spaced symmetry are shaped on sprocket (29) and chain bucket (31) respectively, form the effect that strand drives, twin-bucket is excavated.The driving of anistree sprocket wheel (25) makes driving-chain (30) along operation between upper and lower slideway and the end wheel (34), and driving-chain (30) drives sprocket (29) and chain bucket (31) realizes excavating effect.What of driving-chain (30) and chain bucket (31) can be regulated and change the length of digging arm (1).Be shaped on tensioning spring (27) in the middle of last armed lever (26) and the lower arm rod (28), locate the unlikely chain that takes off at end wheel (34) to keep driving-chain (30).The end of digging arm (1) and motion bar (2) connect, to overcome the horizontal moment to last lower arm rod.Last armed lever (26) end is not coaxial with anistree sprocket wheel (25), forms near the moveable hinge with this to connect, and its effect is that the side direction active force that occurs is transferred on the underframe (11), and axle is played a protective role.

The effect of digging arm lifting gear has two, and one makes digging arm (1) according to being round spot with anistree sprocket wheel (25), being that the radius vertical lift excavates with digging arm (1).It two is to (1) fixing trimming moment of digging arm, reduces excavating resistance thereby adjust, and by moving counterweight (10) and manually winding up roller (3) through pulley (15), (16), (19), (20) and (24) jointly cooperation finish.Moving counterweight (10) is along with the lifting of digging arm (1) moves up and down, thereby is called moving counterweight, and it also plays the balanced action of complete machine simultaneously.

Power and drive mechanism are that (7), (21), (22) are formed by diesel engine (8) and axle, adopt three grades of deceleration transmission, and the transmission of power can be used Type B V-belt, TG190 chain, TG254 chain.Diesel engine (8) adopts the jaw clutch transition with axle system (7).Axle system (21) drives driven roller (13), thereby makes the conveying device operation, promptly finishes the process of transporting of being dug material by driven roller (13) scrolling conveyer belt (12) etc.

In frame and walking system, rack section is made up of ladder frame (9), underframe (11), fixed triangle frame (23) and steel cable (14), (17), (18), forms if the tension and compression triangle can alleviate complete machine weight.In running part, chassis (6) is arranged on the track (5), drives chassis (6) by manpower pedal's sprocket wheel (4) and goes up back and forth operation at track (5).Available light rail of track (5) and sleeper are formed, and also can substitute rail by the section bar welding.After the utility model is made, about 2 tons of complete machine weight, when complete machine moved to track one end, the track other end can be dialled with the manpower crowbar and move, to change the job position of complete machine.The length setting on demand of its track length generally is longer than 15 meters and is advisable.
