Description

Miniatur multifunction work vehicle

The utility model relates to and is suitable for multi-purpose small-size multifunction working vehicle, loading, soil-shifting, generating, lifting, roping multi-function operation in municipal administration, the small building engineering construction.

In the small building engineering construction, on the building site with after the concrete place and the cleaning in sandstone place is smooth and the material loading of shovel dress, concrete mixer, the shovel dress of the wasteway lining that digs when the carrying of mini-plant and town road maintenance mostly is manual work, when useless worker is useless, and easy-clear not.The building site that some is provisional will connect power line, illuminating line from far place, both uneconomical, and is also inconvenient.Will satisfy many-sided requirement in the construction of minor works, the machine of simple function is irrealizable on the domestic market at present.

The purpose of this utility model is to provide and can satisfies the many-sided requirement of construction, and desirable suitable multi-purpose multi-function operation car can reduce labor intensity again.

Technical solution of the present utility model is: small-size multifunction working vehicle, constitute by tractor and equipment, on the front power take-off of tractor oil pump is housed, the front and back bridge of tractor chassis is provided with frame, equipment comprises that frame is provided with loading bulldozing device, hanging apparatus, lighting device, roping device, and the chassis of tractor is provided with TRT.

The loading bulldozing device is arranged on the place ahead of tractor, and hanging apparatus is arranged on the rear of tractor.

Load bulldozing device and constitute two four-bar mechanisms by column, elevating ram, swing arm and swing arm, scraper bowl or dozer, dump ram.Hanging apparatus connects the four-bar mechanism that is made of turning arm, amplitude oil cylinder, arm by slew gear, and the arm end is provided with lifting hook, and telescopic outrigger is equipped with on both sides, bottom, frame rear, in the cavity on supporting leg top hydraulic oil is arranged.TRT is connected by belt drive system with the rear-mounted power take-off of tractor by the generator that is located on the tractor chassis.Lighting device is made of the scalable illumination lamp stand and the elevating mechanism that are located on the frame, and elevating mechanism adopts wire rope to connect lamp stand, and wire rope is contained on the capstan winch of crank axle, and the crank axle other end is equipped with ratchet and pawl arrangement.The roping device is to be provided with draw hook at frame rear end.

Describe the utility model in detail below in conjunction with accompanying drawing.

Accompanying drawing 1 is the structural representation of dozer.

Accompanying drawing 2 is a structural representation of the present utility model.

Shown in accompanying drawing 1,2, the utility model mainly is made of dozer 1, tractor 2, swing arm 3, dump ram 4, scraper bowl 5, elevating ram 6, column 7, frame 8, generator 9, belt drive system 10, supporting leg 11, draw hook 12, slew gear 13, crank axle 14, crank 15, illumination lamp stand 16, wire rope 17, amplitude oil cylinder 18, arm 19, hydraulic control system 20 etc.Soil-shifting and loading attachment are arranged on the place ahead of tractor 2, and hanging apparatus is arranged on the rear of tractor 2, and generator 9 is arranged under the driver's seat, like this, makes complete machine guarantee good stability.

Frame 8 is fixed by bolts on the front and back bridge of tractor 2, column 7 is fixed by bolts on the frame 8, swing arm 3 links to each other with column 7 usefulness bearing pins, a crossbeam with bolt in the middle of the swing arm 3 of the motor both sides of tractor 2, guaranteed swing arm 3 synchronization liftings of both sides, elevating ram 6 one ends link in the lower end of column 7, and dump ram 4 one ends are by bearing pin and swing arm 3 hinge joints, other end hinge joint is on scraper bowl 5, and the front end of swing arm 3 links to each other with scraper bowl 5 usefulness bearing pins.On the front power take-off of tractor 2 oil pump is housed, behind the engine running of tractor 2, the oil pump in the hydraulic control system 20 begins fuel feeding, move manual operation valve, elevating ram 6 drives swing arm 3 liftings, and dump ram 4 drives the scraper bowl upset, achieves load function.

Bearing pin on the scraper bowl 5 of swing arm 3 front ends is taken off, change scraper bowl 5 into shown in the accompanying drawing 1 dozer 1, use the same hydraulic control system of loading to realize the function of bulldozing.

Generator 9 is fixedly mounted under the driver's seat, there are four expansion screws at four angles, can adjust the belt degree of tightness, on the axle of generator 9 passive belt wheel is housed, on the rear-mounted power take-off of tractor 2 driving pulley is housed, the rear-mounted power take-off rotation makes belt drive system 10 drive generator 9 running generatings, and generated output power is 8 kilowatts.

Illumination lamp stand 16 is fixedly mounted on the frame trailing flank, and lamp stand 16 connects wire rope 17, and wire rope 17 is contained on the capstan winch of crank axle 14, and the other end of crank axle 14 is equipped with ratchet and pawl arrangement.Shake crank 15 clockwise, end capstan winch on the crank axle 14 makes wire rope 17 will throw light on lamp stand 16 by the joint extraction, the click of the other end on the crank axle 14 can make lamp stand rest on arbitrary height, ratchet is depressed, clockwise direction is pushed down crank 15, shake crank 15 then counterclockwise, lamp stand is promptly collapsible.

Arm 19 is scalable under the drive of telescopic oil cylinder, slew gear 13 has hydraulic motor, hydraulic motor makes hanging apparatus do 360 ° revolution through deceleration system, amplitude oil cylinder 18 is equipped with on the top of arm 19, there is telescopic outrigger 11 on both sides, slew gear 13 bottom, in the cavity on supporting leg 11 tops hydraulic oil is arranged, lifting and dress push away and use same fuel tank, and both sides interconnect, and lifting and dress push away and also use same oil pump, oil pump is installed on the front power take-off of tractor 2, behind the engine running of tractor 2, oil pump feed is moved manual operation valve and is propped supporting leg 11, the separation handle of rear-mounted power take-off is engaged, generator for electricity generation is used in rear-mounted power take-off rotation, drives hoist engine by the lifting hook weight that hoists, and handles hand-operated valve and makes arm 19 flexible, amplitude oil cylinder 18 luffings can carry out lifting operation.
