Novel tracked bulldozer

Abstract

The invention discloses a novel tracked bulldozer comprising two tracks, a cab, an engine, a base, a motor, a rotating shovel, connecting arms, a roller, a first lifting arm and a second lifting arm. The tracks are symmetrically mounted on two sides of the base. The cab is disposed at the upper end of the base. The engine is disposed at the rear end of the cab. The rear ends of the connecting arms are arranged on two sides of the tracks. The rotating shovel is disposed between the front ends of the connecting arms. One side of the rotating shovel is connected with the motor and a transmission case. One end of the first lifting arm is connected to the middle of one connecting arm; the other end thereof is connected with the base. The roller is mounted on the connecting arms at the rear end of the rotating shovel; the second lifting arm is disposed between the roller and the connecting arms. At least three crescent shovels arranged in symmetry are arranged on the surface of the rotating shovel. The novel tracked bulldozer with a push shovel unit modified has the advantages that stones on the ground can be easily pushed, work efficiency is improved, the service life of the push shovel is prolonged, and the engine is protected.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, and in particular relates to a novel crawler bulldozer. Background technique [0002] Track-type bulldozer A tractor-driven machine having a broad, blunt horizontal blade used for clearing land, road structures, or similar work. Commonly used in the construction industry, track-type bulldozers have a hydromechanical transmission and are operated Flexible, high work efficiency, but the existing crawler bulldozers have a big disadvantage, the heavier they are pushed, the engine will be seriously damaged, and the working targets of the bulldozers are sand, soil and stones, and the stones in the working targets will hinder the pushing The work of the shovel reduces the work efficiency and damages the push shovel, thereby shortening the service life of the push shovel; and the road surface pushed by the push shovel is uneven, and the road surface pushed by the push shovel needs to b...

[0002] Track-type bulldozer A tractor-driven machine having a broad, blunt horizontal blade used for clearing land, road structures, or similar work. Commonly used in the construction industry, track-type bulldozers have a hydro-mechanical transmission and are operated Flexible and high work efficiency, but the existing crawler bulldozers have a big disadvantage, the heavier they are pushed, the engine will be seriously damaged, and the working targets of the bulldozers are sand, soil and stones, and the stones in the working targets will hinder the pushing The work of the shovel reduces the work efficiency, and also damages the push shovel, thereby shortening the service life of the push shovel; moreover, the road surface pushed by the push shovel is uneven, and the road surface pushed by the push shovel needs to be leveled later, which increases the work intensity
