Description

Soil loosening device of bulldozer

Technical Field

The utility model relates to a bull-dozer technical field especially relates to a device that loosens soil of bull-dozer.

Background

A bulldozer is an earthwork machine capable of excavating, transporting and discarding rock and soil, and has wide application in open-pit mines. For example, for construction of refuse dumps, levelling of automobile refuse dumps, accumulation of dispersed rock, levelling of work pans, construction sites, etc.

At present, in the work progress on building site, often need push away the construction site through the bull-dozer and tie to be convenient for subsequent construction work, but partial building site's soil is because harden or the comparatively closely knit reason of soil, and the work efficiency who causes the bull-dozer is not high, and the work progress of bulldozing slowly can lead to subsequent construction date to be held off moreover, consequently, we have proposed the device that loosens the soil of a bull-dozer and have solved above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming that the work efficiency of a bulldozer is not high because of hardening or soil compaction reasons existing in the prior art, and providing a soil loosening device of the bulldozer.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a device loosens soil of bull-dozer, includes dozer blade and motor, the motor is installed on one side outer wall of dozer blade, and is fixed with the second sprocket on the output shaft of motor with one heart, the bottom of dozer blade is provided with the portion of loosening the soil, the portion of loosening the soil includes the mounting base, the inside cavity that is provided with of mounting base, and the mounting base keeps away from one side of dozer blade is rotated through the connecting axle and is installed the toper and bore, the connecting axle other end extends to in the cavity, and the inner of connecting axle is fixed with first gear with one heart, rotate between the inner wall of cavity both ends and install the rotation axis, be fixed with second gear and first sprocket on the rotation axis, second gear and first gear engagement.

Preferably, the first chain wheel is connected with the second chain wheel through a chain.

Preferably, the number of the taper drills is three to sixteen, and the number of the taper drills is the same as that of the first gears and that of the second gears.

Preferably, the first gear and the second gear are both helical gears, and the first gear and the second gear correspond to each other one to one.

The utility model has the advantages that:

the motor drives the conical drill to rotate at the front end of the dozer blade, so that in the process of bulldozing, the conical drill drills compact soil to make the soil loose, the operation of the bulldozer is facilitated, and the working efficiency is improved.

Drawings

Fig. 1 is a schematic structural view of a ripping apparatus of a bulldozer according to the present invention;

fig. 2 is a schematic structural view of a soil loosening portion in the soil loosening device of the bulldozer according to the present invention.

In the figure: the device comprises a soil pushing shovel 1, a motor 2, a mounting base 3, a conical drill 4, a connecting shaft 5, a first gear 6, a rotating shaft 7, a second gear 8, a first chain wheel 9, a second chain wheel 10 and a chain 11.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a soil loosening device of a bulldozer comprises a blade 1 and a motor 2, the motor 2 is a servo motor, the blade 1 is installed at the front end of the bulldozer, the motor 2 is installed on the outer wall of one side of the blade 1 through a bolt, a second chain wheel 10 is concentrically fixed on the output shaft of the motor 2, the second chain wheel 10 is located inside the bulldozer, a cavity matched with the blade is formed inside the bulldozer, a soil loosening part is arranged at the bottom end of the blade 1, the soil loosening part comprises a mounting base 3, the mounting base 3 is installed at the front end of the blade 1 through a screw, a cavity is formed inside the mounting base 3, a tapered drill 4 is rotatably installed at one side of the mounting base 3 far away from the blade 1 through a connecting shaft 5, the connecting shaft 5 is rotatably installed on the mounting base 3 through a bearing, the number of the tapered drills 4 is 8, the other end of each connecting shaft 5 extends into the cavity, and the inner of connecting axle 5 is fixed with first gear 6 with one heart, the bearing is rotated between the inner wall of cavity both ends and is installed rotation axis 7, be fixed with second gear 8 and first sprocket 9 on the rotation axis 7, the quantity of second gear 8 is eight, second gear 8 meshes with first gear 6, second gear 8 are helical gears, and first gear 6, second gear 8 one-to-one, first sprocket 9 is located the one side that is close to second sprocket 10, and, connect through chain 11 between first sprocket 9 and the second sprocket 10.
