Abstract

The utility model relates to a bulldozer blade, particularly the bulldozer blade assembled on a bulldozer. The bulldozer blade is designed mainly for solving the problem that soil is taken back when the bulldozer blade is operated on an upslope or soil humidity is excessively great of the existing bulldozer blade. A method is mainly that elongated holes are arranged on reinforcement ribs on the left and the right sides of the back surface of a bulldozer blade surface. A left bulldozer blade arm is connected with a right bulldozer blade arm by a cross beam. The bulldozer blade arms is connected with the bulldozer blade surface by a pin axle through a short arm on the cross beam. Thus, an angle between a vehicle body and the bulldozer blade surface is changed optionally according to an angle between the vehicle body and a ground. Thus, the problem that soil is taken back when the bulldozer blade is operated on an upslope or soil humidity is excessively great can be solved.

Description

Dozer

The utility model relates to a kind of dozer that is contained on the bulldozer.

Existing dozer comprises parts such as shovel face and shovel arm, and the front end of shovel arm is fixed on the back of shovel face, and the rear end of shovel arm is fixed on the shovel beam of car below.Shortcoming is the shovel face when going up a slope or soil property humidity is carried back native clay when excessive, and operating efficiency is reduced.

The purpose of this utility model be a kind of shovel face of design when going up a slope or soil property humidity do not carry back soil or band soil seldom, the dozer of increasing work efficiency when excessive.

The purpose of this utility model is achieved in that in the back side of shovel face 5 and arranged on left and right sides respectively establishes reinforcing rib one, the per pass reinforcing rib all is made up of two muscle, the corresponding elongated hole 12 of establishing on two muscle, elongated hole has certain lonely degree, and the size of lonely degree adapts with the lonely degree of shovel arm motion; The front portion of left and right two shovel arms 7 has crossbeam to link, and respectively establishes a galianconism about crossbeam the place ahead, establishes pin-and-hole on galianconism, so that be fixed in the elongated hole with bearing pin 11; In the middle of two elongated holes of shovel face back side reinforcing rib, establish pin 3, pin links to each other with pin pull bar 1, the pin pull bar other end leads to driver's cabin, so that the Push And Release of control pin, pin will be inserted in the lower end that the interior bearing pin of galianconism front aperture is fixed on elongated hole at ordinary times; Establish spud pile 9 in existing dozer baffle plate inboard, establish steady brace 8 at shovel on the arm, the front end of steady brace has hook, is hooked on the spud pile at ordinary times, in case incline in face of the shovel when bulldozing; On the steady brace lower crossbeam position corresponding, establish pole 10,, make the disengaging of its hook and spud pile so that the shovel arm boosts steady brace when upwards lifting with it.When the shovel face goes up a slope or soil property is crossed when sticking, can before reversing, spur the pin pull bar, open pin, at this moment lift the shovel arm, steady brace breaks off relations, and shovel inclines in front, and soil is not taken back.

Upper and lower mobile in elongated hole in order to prevent to be inserted in the bearing pin wearing and tearing of galianconism front end and to be convenient to bearing pin, can be at bearing pin peripheral hardware axle sleeve, axle sleeve divides three sections, and go here and there in the hole of galianconism in the stage casing, and left and right two sections strings are in the elongated hole on left and right both sides.

The utility model has the advantages that: can be when operation according to the angle on car body and ground, at any time change the angle of car body and shovel face, solved the shovel face when going up a slope or the soil property humidity problem of carrying back native clay when excessive with regard to emphasis like this, under the situation of equal oil consumption, improve work efficiency 15-30%, can improve work efficiency 1-2 times even more when on dam abutment, bulldozing, use this dozer, must not increase hydraulic means on the bulldozer, flexible operation, firm and durable.

Accompanying drawing is an overall schematic of the present utility model, among the figure: 1, pin pull bar; 2, baffle plate; 3, pin; 4, extension spring; 5, shovel face; 6, pin fulcrum; 7, shovel arm; 8, steady brace; 9, spud pile; 10, pole; 11, bearing pin; 12, elongated hole.

Below in conjunction with accompanying drawing the utility model is further described: at first respectively establish reinforcing rib one in the back side and arranged on left and right sides of shovel face, the per pass reinforcing rib all is made up of two muscle, on two muscle, establish same elongated hole, the lonely degree of elongated hole is the r230 millimeter, the anterior welding of left and right two shovel arms one crossbeam links, left and rightly in crossbeam the place ahead respectively establish a galianconism, on galianconism, establish pin-and-hole; Establish pin in the middle of two elongated holes of shovel face back side reinforcing rib, pin links to each other with the pin pull bar, and the pin pull bar other end leads to driver's cabin; Establish spud pile in dozer baffle plate inboard, establish steady brace on the shovel arm, the steady brace front end is established hook; At bearing pin peripheral hardware axle sleeve, axle sleeve divides three sections.

Claims

1, dozer relates to a kind of dozer that is contained on the bulldozer, comprise shovel face, shovel arm etc., it is characterized in that respectively establishing reinforcing rib one in the back side and arranged on left and right sides of shovel face [5], the per pass reinforcing rib all is made up of two muscle, the corresponding elongated hole [12] of establishing on two muscle, the front portion of left and right two shovel arms [7] has crossbeam to link, about crossbeam the place ahead, respectively establish a galianconism, on galianconism, establish pin-and-hole, in the middle of two elongated holes of shovel face back side reinforcing rib, establish pin [3], pin links to each other with pin pull bar [1], and the pin pull bar other end leads to driver's cabin; Establish spud pile [9] in the baffle plate inboard, establish steady brace [8] on the shovel arm, the front end of steady brace has hook, establishes pole [10] on the position corresponding with it of the crossbeam below the steady brace.

2, according to the said dozer of claim 1, it is characterized in that bearing pin peripheral hardware axle sleeve, axle sleeve divides three sections.
