Description

A kind of loader

The utility model relates to a kind of construction machinery and equipment, especially relates to a kind of small sized loader that is used to load and transport material.

At present, people are in the building ground, the Bricks and Tiles Plant, the sandstone field, environmental sanitation, gardens, the material loading that use in places such as harbour, entrucking, heap is high, site clearing machinery, mostly be ZL30 greatly, the heavy construction loader of models such as ZL50, its shoveling and loading device is the general pair shovel arms that adopt on the needs structure that adapts to big carrying capacity, two lifting hydraulic cylinders, join single upset hydraulic actuating cylinder and handle scraper bowl, characteristics are: power is big, the efficient height, it is big to be fit to the operation place, the occasion that working out is many, but hydraulic system structure complexity, cost an arm and a leg, the expense height of operating maintenance need have the professional to operate, what past-sale service inconvenience, influence were used popularizes.

The purpose of this utility model provide a kind of structure and manufacturing process simple, operation army cost is low, uses flexibly, uses small sized loader easy to maintenance.

For achieving the above object, the utility model adopts following technical solution: a kind of loader, comprise driving engine, vehicle frame, front driving axle, rear driving axle, operator's compartment, auxiliary gear box, transmission shaft, Hydraulic Pump and pipeline, preceding pedestal, back basigamy is heavy, scraper bowl, the shovel arm, overturning oil cylinder, elevating ram, turn to oil cylinder etc., adopt articulated structure between preceding pedestal and the vehicle frame, the power of driving engine is delivered to front driving axle and rear driving axle respectively through auxiliary gear box, it is characterized in that: shovel arm front end is forked two point symmetry structures, with the scraper bowl bottom-hinged, its rear end and preceding pedestal medium position are hinged; Overturning oil cylinder is positioned on the shovel arm, its afterbody and preceding pedestal top upper articulation, and its cylinder bar front end and pipe link middle part are hinged; Elevating ram is positioned under the shovel arm, tail end and preceding pedestal lower hinge, and its cylinder bar front end is hinged with shovel arm middle part; The pipe link lower end is hinged with the shovel arm, and upper end and torque arm one end are hinged, and the torque arm other end and scraper bowl rear wall upper edge are hinged, and scraper bowl rear wall, torque arm, pipe link, shovel arm leading portion are formed four-bar linkage; Shovel the longitudinal centerline of arm, elevating ram, overturning oil cylinder, torque arm, pipe link etc., all be positioned at the longitudinal plane of loader.

After adopting said structure, former two shovel arm makes forked single shovel arm into, former pair of elevating ram makes single elevating ram into, material cost significantly reduces, hydraulic efficiency pressure system does not need to consider the stationary problem of twin-tub, simple in structure, adopt small power motor can satisfy operating needs, solve little working out place and used large-duty loader " to break a fly upon a wheel ".Make operating cost improve problem, and, maintenance is more prone to because hydraulic ram reduces, and hydraulic efficiency pressure system is simplified.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of loader of the present utility model.

Loader shown in Figure 1 by driving engine 21, front driving axle 15, rear driving axle 20, operator's compartment 19, transmission shaft 16, auxiliary gear box 18, Hydraulic Pump 23, preceding pedestal 13, back basigamy weigh 24, turn to oil cylinder 17, scraper bowl 6, shovel arm 10, elevating ram 12, overturning oil cylinder 11 etc. form.Driving engine 21 is installed in rear portion on the vehicle frame, operator's compartment 19 is positioned at complete machine middle part on the vehicle frame, and preceding basic Cuo 13 is positioned on the front driving axle 15, is articulated structure with vehicle frame in the middle of it, by about turn to oil cylinder 17 that front driving axle 15 is turned an angle, in order to steer direction.Give front driving axle 15 and rear driving axle 20 by auxiliary gear box 18 and transmission shaft 16 with power distribution from the power of driving engine 21, and by driving Hydraulic Pump 23, through hydraulic tubing, control cock, hydraulic coupling is passed to elevating ram 12, overturning oil cylinder 11, turns to oil cylinder 17.In preceding pedestal 13 middle upper portion from the top down, use bearing pin 1 hinged overturning oil cylinder 11 afterbodys successively, bearing pin 2 hinged shovel arm 10 afterbodys, bearing pin 14 hinged elevating ram 12 afterbodys.Shovel arm 10 front ends become forked hinged with bearing pin 8 with 2 of scraper bowl 6 bottoms, elevating ram 12 cylinder bar front ends are hinged with bearing pin with shovel arm 10 middle parts, on scraper bowl 6 rear walls, continue to use bearing pin 5 and connect arm 7 front ends hinged, torque arm 7 rear ends and pipe link 3 upper ends are hinged with bearing pin 4, pipe link 3 lower ends are hinged with bearing pin 9 with shovel arm 10 middle parts, scraper bowl 6, torque arm 7, pipe link 3, shovel arm 10 are formed four and are linked structure, and overturning oil cylinder 11 cylinder bar front ends and pipe link 3 middle parts are hinged with bearing pin.By handling the flexible of overturning oil cylinder 11 cylinder bars, scraper bowl 6 is turned an angle around bearing pin 8; By handling the flexible of elevating ram 12 cylinder bars, shovel arm 10 is turned an angle around bearing pin 2.Preceding pedestal 13 and back basigamy weigh and all load weight in 24, to keep the balance in the use.

Concrete condition of service is: at first scraper bowl 6 is placed and can shovel the state of going into material, driving loader then makes scraper bowl 6 put into material, control hydraulic system shrinks overturning oil cylinder 11 again, by torque arm 7 scraper bowl 6 is rotated around bearing pin 8, during Deng scraper bowl 6 basic maintenance level suitable for reading, handle elevating ram 12, shovel arm 7 rotates around bearing pin 2, make scraper bowl 6 raise certain height, can drive loader in case of necessity or do suitable turning to, then control hydraulic system makes overturning oil cylinder 11 elongations, and scraper bowl 6 rotates around bearing pin 8 and unloads material, make scraper bowl 6 be in incipient state on the other way around at last, in order to carrying out the next round operation.
