Efficient precision fertilizer distributing and seed sowing machine

Abstract

The invention discloses an efficient precision fertilizer distributing and seed sowing machine. The machine comprises an umbrella-type fertilizer distributing device, a fertilizer stirrer, a fertilizer can and a chassis, wherein the fertilizer stirrer is arranged at the lower end of the fertilizer can; the umbrella-type fertilizer distributing device capable of flexibly adjusting the working size of a fertilizer distributing plate is arranged on the chassis and below the fertilizer stirrer; the umbrella-type fertilizer distributing device is connected with a fertilizer distributing driving device; the fertilizer stirrer is connected with a fertilizer stirrer driving device; a column is arranged on the chassis; a support frame and a suspension strut beam are arranged on the column; and the fertilizer can with height adjustable is arranged on the column via the support frame and the suspension strut beam. The machine has the following advantages: the machine is suitable for distributing and applying granular and powdery fertilizers and can sow crop seeds; the distributing and sowing precision is controllable; and the distributing and sowing width is efficient, continuous and adjustable.

Description

technical field [0001] The invention relates to a centrifugal disc type fertilizer spreader and seeder, in particular to a high-efficiency precision fertilizer spreader and seeder used for spreading fertilizer and crop seeds in paddy and dry fields. Background technique [0002] Rice, wheat and other crops have many fertilization operations during the growth period, and the workload of manual fertilization and sowing is large, which occupies a large amount of agricultural labor, and the efficiency is low, the labor intensity is high, and the human body is directly in contact with chemical fertilizers, which will also affect the health of the body. Artificial fertilization and seeding, uneven spreading, excessive use of chemical fertilizers, causing environmental pollution, compacting the soil, and reducing soil quality. Mechanized precision fertilization and seeding can double the efficiency, spread evenly, control the amount of spreading, reduce the loss and volatilization ...

AI Technical Summary

Problems solved by technology

[0004] 1) The fertilizer spreader of the fertilizer spreading device is generally designed as a single fixed diameter, and the adjustment of the fertilizer spread width is mainly realized by the change of the speed of the fertilizer spreader, and the range of the fertilizer spread speed is limited, and the adjustment range of the fertilizer spread width is not large. Unsuitable for continuous and efficient fertilizer spreading

[0005] 2) It is generally used with agricultural tractors. Once the fertilizer spreader is mounted and positioned, it is difficult to adjust the working height of the fertilizer spreader and the fertilizer box, which cannot adapt to the paddy and dry field operation conditions with large fluctuations in terrain.

[0006] 3) When the viscosity or humidity of the fertilizer particles is high, the fertilizer particles are easy to agglomerate, and relying solely on the gravity of the material is not enough to overcome the resistance, causing the material to block the bottom of the fertilizer tank and cannot fall continuously and stably

[0007] 4) The fertilizer mixer generally rotates coaxially with the fertilizer spreader, and the speed adjustment range is limited. When the speed is high, the impact force is too large, and the fertilizer particles are broken too finely, resulting in fertilizer atomization drift and large losses

[0008] 5) The fertilizer mixer and fertilizer spreading device adopt mechanical variable speed, the speed range is small, and cannot be adjusted continuously, it is difficult to adapt to the requirements of different fertilizers and crop seeds mixing and precision variable spreading
