Description

Scraper cleaning device for agricultural land leveler

Technical Field

The utility model relates to an agricultural land leveler technical field especially relates to an agricultural scraper cleaning device for land leveler.

Background

The agricultural land leveller consists of frame, traction (or suspension) device, land leveling shovel and its operation and regulation device and scarification shovel. The anti-profiling device has the anti-profiling performance that the land leveling shovel does not move up and down along with the fluctuation of the ground surface so as to obtain the effect of leveling the farmland. There are 3 types of agricultural graders: the traction type land leveler (shown in the figure) has the advantages of large longitudinal span, larger distance between the dozer blade and the rear wheel of the tractor, good anti-profiling performance, good land leveling quality and reliable work, but has more complex structure and large metal consumption, and is suitable for large-area land leveling operation. The walking device has two types, namely a four-wheel type walking device and a two-wheel type walking device. The front ends of the two wheels are supported by a tractor. The suspended land leveler has the advantages of simple structure, light weight, less steel consumption, flexibility in maneuvering, small longitudinal span, small distance between the land leveling shovel and the rear wheel of the tractor, poor anti-profiling performance and poor land leveling quality, and is suitable for small land operation. The front end of the frame of the semi-suspension type land leveller is articulated with the suspension mechanism of the tractor, and the rear end is provided with a supporting wheel. Compared with a traction type, the structure is simpler, the weight is lighter, the operation is convenient, and the quality of the ground is better in suspension type.

As a general agricultural land leveler, the scraper is used for correcting the earthwork in the operation process, the scraper is positioned between a front wheel and a rear wheel, the scraper has the characteristics of moving left and right, ascending and descending, and working conditions are stable, the land leveling has quite high precision, the scraper is suitable for uneven agricultural land, the side edge of a gap is excavated, accumulated snow on the road surface is swept, most of soil is wet and melted in the agricultural operation, the scraper of the land leveler inevitably accumulates clay on the scraper, the ground is not easy to level, the leveling efficiency of the whole land leveling is affected, the difficulty of the land leveling is increased under the condition, time and oil are wasted, and soil moisture can be soaked into the scraper to gradually rust the scraper, so that the service life of the agricultural scraper is shortened, and the loss rate is increased.
