Multifunctional variable fertilizer distributor for field

Abstract

The invention relates to a multifunctional variable fertilizer distributor for a field. The multifunctional variable fertilizer distributor comprises a fertilizer box mounted above a main transmission shaft, wherein a protective device is fixed at the front end of the fertilizer box; the rear part of the fertilizer box is hinged to a fertilizer striking roller fertilizer throwing mechanism through a connection piece; the fertilizer striking roller fertilizer throwing mechanism comprises baffles mounted on two sides; at least one group of fertilizer striking rollers are fixed in each baffle; a conical disk fertilizer scattering mechanism parallel to the fertilizer box is arranged below the fertilizer striking rollers; a ratchet wheel speed adjustment mechanism is mounted on one side of each baffle; the ratchet wheel speed adjustment mechanisms are connected with a chain plate fertilizer conveying mechanism inside the fertilizer box; hydraulic opening and closing mechanisms are fixed on box plates on two sides of the fertilizer box; and the fertilizer scattering amount is controlled according to the opening and closing degrees of the hydraulic opening and closing mechanisms. The multifunctional variable fertilizer distributor for the field can quantitatively scatter and apply fertilizer with various characters, and can scatter organic fertilizer and precisely scatter chemical fertilizer. Furthermore, the fertilizer conveying amount can be precisely adjusted, the aims of applying fertilizer as required, saving fertilizer and enhancing the effect are fulfilled, and a technical support is supplied to sustainable development of agriculture in China.

Description

technical field [0001] The invention relates to a fertilizer spreader, in particular to a field multifunctional variable fertilizer spreader, which belongs to the technical field of agricultural machinery. Background technique [0002] Excessive application of chemical fertilizers not only causes continuous pollution of water bodies, but also increases the residues of toxic substances in agricultural products, leading to eutrophication of surface water, excessive nitrate nitrogen content in groundwater and vegetables, etc. Structural imbalance, deterioration of physical properties, and excessive levels of harmful metals and harmful bacteria in some plots lead to a decline in fertility and deterioration of soil properties, and also bring great harm to the sustainable development of agriculture. [0003] At present, the average amount of chemical fertilizer per mu of crops in my country is 21.9 kg, far higher than the world average of 8 kg per mu, 2.6 times that of the United ...

AI Technical Summary

Problems solved by technology

However, the amount of organic fertilizer spread per mu is relatively large. At present, it mainly relies on manual fertilizer spreading. The work intensity is high, the environment is harsh, and the efficiency is low, which seriously hinders the development of the organic fertilizer industry. At present, some domestic enterprises and scientific research units use organic fertilizer. The equipment is researched, but there are not many products that have been introduced to the market. The fertilizer spreader on the market has a single function and can only spread fertilizer for one kind of fertilizer, and the fertilizer spread is rough, and the amount of fertilizer spread cannot be precisely controlled, resulting in excessive fertilizer spread. It cannot be fertilized on demand, it cannot meet the market demand, and it cannot meet the on-demand spreading of fertilizers with various properties
