Problems solved by technology

Moreover, there are still some large-sized stones exposed on the surface after leveling the road surface, which is easy to cause scratches to the tires of the driving equipment.
The main function of the rear ripper configured on the conventional grader is to rake the hard road surface, which has little effect on the cleaning

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0022] Such as figure 1 As shown, a rear moldboard of a motor grader includes a gear holder 6, on which a four-bar linkage mechanism is fixed, the four-bar linkage mechanism is driven by an oil cylinder 4, and the gear holder 6 is fixed by a mounting plate There is a moldboard 12, and the four-bar linkage drives the whole moldboard 12 to move up and down under the telescopic action of the oil cylinder 4.

[0023] The four-bar linkage mechanism includes a mounting seat plate 1, a first connecting rod 2, a second connecting rod 3-1, a third connecting rod 3-2, and a rack 5 connected in sequence by pin shafts. The first connecting rod 2 is an integral weldment; the front of the first connecting r...

Abstract

The invention discloses a rear clean-up scraper for a land leveler. The rear clean-up scraper for the land leveler comprises a mounting seat plate (1) and a four-bar linkage connected with the mounting seat plate (1); the four-bar linkage is driven by an oil cylinder (4) and connected with a gear rack (5); the gear rack (5) is fixed on a gear seat (6), and a clean-up scraper (12) is fixed to the gear seat (6) through a mounting plate; and the four-bar linkage drives the entire clean-up scraper (12) to move up and down under the telescopic action of the oil cylinder (4). According to the rear clean-up scraper for the land leveler, the two-times leveling of the land leveler can be realized through a single trip, the working efficiency is improved, the replacement time of a shovel blade is prolonged and at the same time, larger stones with irregular particle sizes on the surface are cleaned up, the leveling quality is improved, and the scratches on tires of road driving equipment are reduced.

Description

technical field [0001] The invention relates to a rear scraper for a motor grader, which belongs to the technical field of engineering machinery. Background technique [0002] In addition to leveling the soil road surface of conventional roads at all levels, the grader will also level and pave the gravel road surface, especially in open-pit mines, the grader is used for road maintenance to protect the tires of heavy mobile equipment in the mine, reduce tire wear and tear. scratched. The maintenance of gravel pavement does not require high leveling accuracy, but the particle size and medium density of gravel are relatively large, and the leveling area is large, which seriously wears out the blade. The same working surface often needs to go back and forth twice for leveling maintenance. Firstly, large gravel is cleaned, and then the road surface is maintained for the second time. Moreover, there are still some stones with large particle sizes exposed on the surface after lev...
