A rear throw type grass and soil separation shallow loosening shovel

Abstract

The invention belongs to the technical field of agricultural machinery and particularly relates to a back-throwing type topsoil cultivation shovel for separating grass and soil. The grass and the soil are shoveled by topsoil cultivation shovel wings and pushed backward. Soil smashing rollers on the back side of the topsoil cultivation shovel are driven by a driving wheel to quickly rotate clockwise. Harrow teeth on the soil smashing rollers are stirred to smash soil blocks to separate the grass and the soil, the grass and the soil are thrown backward quickly to be separated further and enable weeds to be buried in the soil, the weeds can return to the field easily, and humus of weed rot can improve the nutrient in the soil, loosen the soil and increase the content of air and water in the soil. Compared with the existing topsoil cultivation shovel, the weeding rate is high, the effect of the loosening of the topsoil is remarkable, the grass and the soil separation effect after topsoil cultivation is good, and the back-throwing type topsoil cultivation shovel is favorable for improving the breathability of a seedbed and enables crop roots to be developed.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a rear-throwing shallow loosening shovel for separating grass and soil. Background technique [0002] Shallow loosening machine is a kind of surface soil tillage equipment commonly used in the promotion of conservation tillage technology, and it is mainly suitable for pre-sowing soil preparation of dryland conservation tillage. The effect of soil loosening, weeding and soil preparation of the shallow loosening machine mainly depends on the shallow loosening shovel. Therefore, the shallow loosening shovel is the core working part of the shallow loosening machine. [0003] In order to improve the loosening, weeding and soil preparation effects of shallow loosening machines, researchers have developed a series of shallow loosening machines and shallow loosening shovels. For example, the utility model patent 200420112778. The shovel achieves the purpose of...

Problems solved by technology

[0003] In order to improve the loosening, weeding and soil preparation effects of shallow loosening machines, researchers have developed a series of shallow loosening machines and shallow loosening shovels. For example, the utility model patent 200420112778. The shovel achieves the purpose of weeding and loosening the soil, but the grass-soil separation effect is poor after shallow loosening, and the weed killing rate is low

Another example is the utility model patent 200820122769.0 which discloses a ridge farming cover type spraying shallow pine weeder. After using the wing type shallow pine weeding and eradicating weeds, the weeding effect is enhanced by installing a chemical spraying device. The pollution of the environment, the cost of farming, will also increase the counterweight of the machine

Although these shallow loosening machines have achieved the purpose of loosening soil, weeding, and site preparation to a certain extent, there are still poor grass-soil separation effects after shallow loosening, most of the weed root system is still combined with the soil after weeding, and the weed killing rate is low. question
