Abstract
The utility model provides a small loader, basically comprising a bucket, a bucket bracket, a counterweight, a hydraulic transmission device, and a small four-wheel tractor. The utility model is characterized in that a steering device of the small four-wheel tractor is a hydraulic steering device. In order to prevent vehicle wheels from skidding when working, the rear wheels at two sides of the small loader are dual rear wheels structure. By adopting the hydraulic steering, the small loader of the utility model has flexible steering, and effort-saving driving; the vehicle wheels of the machine adopting the dual rear wheels are not skidded or hardly skidded when working. The small loader is in particular suitable for the fields such as farmland water conservancy construction, building construction, cement workshops, coal factories, etc. with simple structure and convenient generalization.
Description
Affiliated technical field
The utility model relates to a kind of small sized loader, is the modified product of small four-wheel tractor, belongs to the loading machine technical field.
Background technology
The small sized loader of existing multiple in the market small four-wheel tractor repacking comes out, its advantage is a low cost of manufacture, and is of many uses, as is used for construction of water conservancy works, building operation, cement products factory, coal works etc., its weak point are that this loader makes the small four-wheel tractor as main frame increase counterweight, scraper bowl, support arm, the heavy burden of parts such as hydraulic actuator also needs to increase the load-carrying load when work, chaufeur is driven when work turned to special effort.
Summary of the invention
The purpose of this utility model is to provide a kind of driving to turn to the labour-saving small sized loader flexibly.
The technical solution of the utility model is achieved in that this small sized loader, and its basic structure comprises scraper bowl, dipper frame, and counterweight, hydraulic actuator and small four-wheel tractor, its feature is that the deflector of described small four-wheel tractor is a hydraulic steering gear.
The tyre skidding of small sized loader when preventing work, the both sides trailing wheel of described small sized loader is the double rear wheel structure.
The rectangular recess of the hydraulic steering gear of described small sized loader turns to the rectangle coupling end of interface and steering wheel shaft lower end to join, be connected with fuel feed pipe between the former plunger pump of hydraulic steering gear and small four-wheel tractor rear cover assembly or gear type pump, it is hinged that cylinder bar that turns to oil cylinder that links to each other with the hydraulic steering gear pipeline and small four-wheel tractor former turns to, and turns to the rear end of the cylinder block of oil cylinder and vehicle frame hinged.
The dipper frame of described small sized loader comprises principal post and lifting arm again, the vehicle frame of principal post lower end and small four-wheel tractor is fixed, the two ends of lifting arm are hinged with principal post and scraper bowl respectively, the cylinder bar of the hoist cylinder in the middle and described hydraulic efficiency gear is hinged, the cylinder body lower end and the vehicle frame of hoist cylinder are hinged, the cylinder body of the bucket cylinder of hydraulic efficiency gear and to be fixed in two crossbeams between lifting arm hinged, cylinder bar and scraper bowl swivel arm are hinged.
Be provided with pad between the spoke of the double rear wheel of the both sides trailing wheel of the small four-wheel tractor of described small sized loader.
The small sized loader that the utility model provides has been because adopted fluid-link steering, so turn to flexibly, drives laborsavingly, and the employing double rear wheel can make this machine wheel when working non-slip or skid less.This small sized loader is particularly useful for construction of water conservancy works, building operation, and cement products factory, fields such as coal works, simple in structure, be convenient to promote.
