Coating machine for the production of special biological fertilizer for rice weeding

Abstract

The invention relates to a chemical fertilizer production equipment, in particular to a coating machine for the production of special biological bacterial fertilizer for rice weeding. It includes a bracket, an upper roller rotatably installed on the upper end of the bracket and a drive motor. A track ring and a gear ring are fixedly installed on the outer wall of the upper drum. The gear ring is connected to the drive motor through a drive gear. On the roller, the inner cavity of the upper drum is a conical structure with a small diameter at the front end and a large diameter at the rear end. The rear end of the upper drum is provided with a transfer hopper, the upper end of the transfer hopper is provided with ventilation holes, and the lower end is provided with a discharge pipe. The side wall is connected to the upper roller; the lower roller is rotatably installed below the bracket, the inner cavity of the lower roller is a tapered structure with a large front diameter and a small rear diameter, and the rear end of the lower roller is docked with the discharge pipe. The bio-organic fertilizer production device has reasonable structure and high production efficiency, and can complete granulation, screening, drying and other processes at one time, and at the same time, it can clean the wall material without stopping the machine.

Description

technical field [0001] The invention relates to a chemical fertilizer production equipment, in particular to a coating machine for the production of special biological bacterial fertilizer for rice weeding. Background technique [0002] Biological fertilizer for rice weeding is a multi-functional environment-friendly fertilizer that integrates biological, organic, inorganic, quick-acting and slow-acting fertilizers. The fertilizer has both biological, organic and inorganic components suitable for plant growth, and The quick-acting and slow-acting fertilizers that meet the different growth cycles of plants have the special effect of weeding and soil improvement. It has complete nutrients and long-lasting and stable fertilizer supply, which can improve the utilization rate of chemical fertilizers and reduce the pollution of chemical fertilizers to soil and water systems. However, in the process of production, storage and transportation of this fertilizer, the survival rate of ...

Problems solved by technology

Because ungranulated powder will inevitably be produced during the granulation process, after granulation, it is necessary to use a sieving machine to separate the finished granules from the powder, and the finished granules are sent to the dryer for drying, and the ungranulated powder is recovered and sent to granulation again Machine granulation, such a screening process increases the transportation and turnover of a lot of materials, occupies a large space and has low production efficiency

In addition, in actual use, due to the high humidity of bio-organic fertilizers, it is easy to stick to the inner wall of the drum. If these wall-bound substances are not cleaned in time, they will accumulate more and more, which will seriously affect the quality of granulation.

However, it is necessary to stop the machine to clean up the wall material, and frequent parking will affect the smooth progress of production and reduce production efficiency
