Quantitative fertilization device for agricultural production

Abstract

The invention discloses a quantitative fertilization device for agricultural production. The device comprises a lower shell and a feed hopper, the feed hopper is mounted at the top end of the lower shell, the interiors of the feed hopper and the lower shell are communicated, a power mechanism is mounted on the feed hopper, a feed inlet is formed at the position, located at one side of the power mechanism, of in the feed hopper, a discharge shell is mounted on the surface of the lower shell, a main shaft body is installed in the lower shell, and a material distributing mechanism is installed on the surface of the main shaft body. The material distributing mechanism comprises a propelling shaft body and a feeding impeller, the feeding impeller is installed on the main shaft body, the propelling shaft body is installed in the main shaft body, and an adjusting sleeve is installed on the surface of the propelling shaft body. By arranging a series of structures, the quantitative fertilization device for agricultural production can be convenient to disassemble and clean, meanwhile, stirring and directional feeding operation of fertilizer can be facilitated, and by means of the telescopic effect of an electric push rod, the fertilizer feeding rate is changed in a mode of shielding the impeller, and the quantitative fertilization effect is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a quantitative fertilization device for agricultural production. Background technique [0002] Fertilization refers to the agricultural technical measures of applying fertilizers to the soil or spraying them on the plants to provide the nutrients needed by the plants and to maintain and improve soil fertility. With the development of science and technology, the trend of agricultural mechanization is accelerating, and mechanized fertilization is gradually replacing manual fertilization. [0003] General mechanical fertilization often adopts the method of fixing the fertilization device on the external equipment, such as on the agricultural tractor. However, the existing fertilization device has a strong internal structure stability. If it is necessary to change the export rate of the fertilizer, generally It is to change the power components, such as the speed of t...

Problems solved by technology

[0003] General mechanical fertilization often adopts the method of fixing the fertilization device on the external equipment, such as on the agricultural tractor. However, the existing fertilization device has a strong internal structure stability. If it is necessary to change the export rate of the fertilizer, generally It is to change the power components, such as the speed of the motor, or directly change the opening and closing degree of the output components, but this kind of rate change method is relatively simple, and the flexibility is insufficient. In the process of large-scale fertilization, the fertilizer supply rate cannot be controlled. , it may cause a waste of fertilizer, and even some fertilization devices apply too much fertilizer, which is not conducive to the actual agricultural planting operation
