Self-propelled quantitative fertilizer spreading device and working method

Abstract

The invention relates to the field of agricultural machinery, in particular to a self-propelled quantitative fertilizer spreading device and a working method. The self-propelled quantitative fertilizer spreading device comprises a support frame; the support frame is of a U-shaped structure; the self-propelled quantitative fertilizer spreading device further comprises a controller, a self-propelledmechanism and a spreading mechanism; a partition plate is fixedly arranged in the middle of the inner side of the support frame; the self-propelled mechanism is arranged on two side walls of the support frame to support walking of the device; the self-walking mechanism comprises a first motor, a first rotating shaft and two walking assemblies; the spreading mechanism is arranged at the top of thepartition plate and used for spreading fertilizer; the spreading mechanism comprises a discharging pipe, a pushing assembly, a quantifying assembly and a stirring assembly; and the first motor and the stirring assembly are electrically connected with the controller. According to the self-propelled quantitative fertilizer spreading device and the working method, the fertilizer can be spread synchronously when the device advances, the spreading speed is high, the power consumption is low, and meanwhile the spreading amount is uniform.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a self-propelled quantitative fertilizer spreading device and a working method. Background technique [0002] Agricultural machinery refers to various machinery used in crop planting and animal husbandry production, as well as in the primary processing and handling of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc. [0003] In the process of farmland cultivation, it is necessary to spread solid granular fertilizers or chemical fertilizers. The traditional sowing method relies on manual use of material buckets, and then ma...

AI Technical Summary

Problems solved by technology

[0007] 1. The device needs to be pushed manually. At the same time, the walking mechanism and the spreading mechanism of the device operate independently. The device cannot simultaneously realize the fertilizer spreading while walking, resulting in a large power consumption of the device, which is not conducive to saving electric energy and thus is not conducive to reducing The cost of fertilizer spreading, while the spreading speed is slow, the spreading efficiency needs to be improved

[0008] 2. In the process of fertilizer spreading, since there is no structure designed to control the amount of fertilizer spreading, the amount of fertilizer spreading each time is not uniform, which will easily cause uneven cultivation of crops, and crops that are spread too much fertilizer are easy to burn die, while those with less fertilization are prone to die due to lack of nutrients
