Abstract

The utility model discloses a multifunctional bulldozer with an adjustable shovel surface, being suitable for carrying out fine and smooth construction for ground. The angle between the shovel surface and the ground can be flexibly adjusted through a hydraulic mechanism, so that the multifunctional bulldozer with adjustable shovel surface has the miscellaneous functions of shoveling, pushing and scratching. In addition, vehicles do useful work at the time of advance and retreat, so that the construction quality and efficiency is improved. The utility model is particularly suitable for the leveling construction of large-area grounds which have high requirements for flatness.

Description

Multifunctional bulldozer with adjustable ladle

The utility model relates to a kind of bulldozer, particularly a kind of adjustable shovel face multifunctional bulldozer.

In earth and rock works, the construction in smooth place generally can be finished by bulldozer.But, after the bulldozer construction, still need do further smooth to the demanding large tracts of land of planeness place.Therefore, just need a kind of new machinery, can carry out this finer smooth work, to improve the construction quality and the efficient of engineering.

The purpose of this utility model, a kind of multi-functional bulldozer that can carry out meticulous smooth construction to the place will be provided exactly, it regulates the angle on perching knife and ground by hydraulic mechanism, make it to have and push away, shovel, scrape multiple function, to remedy original bulldozer the deficiency of soil-shifting function is only arranged, finish the work in smooth place fast and efficiently.

The utility model is achieved in that on fluid pressure type soil-shifting machine, shed former dozer blade after, the native cutter of shovel is installed on the position of dozer blade, but considers that being fixedly connected between dozer blade and the push rod connects with activity between the push rod for shoveling native cutter.On the push rod of former bulldozer, load onto a group oil cylinder respectively, be used for adjusting angle and height between native cutter of shovel and the ground with body structure top.Wherein be movable the connection between hue angle oil cylinder group and shovel native cutter and the push rod.Connect that cross bar is movable to be connected between degree of heightening oil cylinder group one end and two push rods, the other end and vehicle body are fixedly connected.During work,, can regulate the angle and height on native cutter of shovel and ground by the action of two group oil cylinders of the HYDRAULIC CONTROL SYSTEM in the former bulldozer, make it to have shovel, push away, scrape multiple function, thereby the adaptation different situations, the different needs of work that require are finished construction task fast and efficiently.

The utility model can adapt to the needs of various earth and rock workses construction, compares with general bulldozer, can carry out the construction of more meticulous levelling of the land, and the car forward and back all does useful work, has improved construction quality and efficient greatly.Be particularly suitable for the smooth construction in large tracts of land place that levelling of the land is had relatively high expectations.

Below in conjunction with accompanying drawing the utility model is described in further details.

Fig. 1 is the utility model schematic perspective view.

Fig. 2 is that the utility model shovels native knife back face schematic diagram.

Fig. 3 is that the utility model shovels native cutter A-A face sectional view.

With reference to Fig. 1, Fig. 2, Fig. 3.The utility model is by vehicle body (1), degree of heightening oil cylinder (2), (3), and native cutter (6) is shoveled in hue angle oil cylinder (4), (5), push rod (7), (8), push rod connects cross bar (9) and forms.

Vehicle body (1) is identical with former bulldozer vehicle body.The cylinder body of degree of heightening oil cylinder (2), (3) is fixedly connected with the upper front end both sides of vehicle body (1) respectively, and their piston rod connects with push rod respectively that cross bar (9) is movable to be connected.The cylinder body end of hue angle oil cylinder (4), (5) is actively connected on respectively on push rod (7), (8), and their tailpiece of the piston rod connects with top connecting ring (10), (11) activity of the native cutter of shovel (6) respectively.The setting of hue angle cylinder block and piston rod length should make the angle theta between native cutter of shovel and the ground, is between 120 °-160 ° when advancing car shovel soil, and optimum value is 150 ° altogether.Reversing is that optimum value is 30 ° between 20 °-60 ° during scraping.Shoveling native cutter (6) is a broken line type steel plate, and there is the edge of shovel lower end, and its back has connecting ring (10), (11), (12), (13) to connect with hue angle oil cylinder (4), (5) and push rod (7), (8) activity respectively.Scraping locating piece (14), (15) are fixedly connected with the native cutter of shovel (6), the angle of formation is to the resistance of native face between the effect of angle theta when they promptly have stable shovel native cutter (6) scraping and between ground, push rod in the time of can alleviating scraping again (7), (8) and the native cutter of shovel (6).Two ends and push rod (7), (8) that push rod connects cross bar (9) are fixedly connected.

During work, the action by the control of the hydraulic control system in original soil bulldozer degree of heightening oil cylinder (2), (3) and hue angle oil cylinder (4), (5) can make it to have shovel, push away, scrapes multiple function.When advancing car shovel soil, the angle theta optimum value of shoveling native cutter (6) and ground is 150 °, best angle θ when advancing the car soil-shifting=95 °-100 °; Best angle θ=30 ° when scraping when moveing backward back.

Claims

1, a kind of adjustable shovel and multi-functional bulldozer is by vehicle body (1), degree of heightening oil cylinder (2), (3), native cutter (6) is shoveled in hue angle oil cylinder (4), (5), push rod (7), (8), push rod connects cross bar (9) and forms.It is characterized in that:

A. the cylinder body of degree of heightening oil cylinder (2), (3) is fixedly connected with the upper front end both sides of vehicle body (1) respectively; Their piston rod connects the movable connection of cross bar (9) respectively with push rod.
