Device and method for spraying bacterial fertilizer

Abstract

The invention discloses a device and method spraying bacterial fertilizer. The device comprises a base plate, a storage box, a pump, a pressure relief and explosion-proof unit and four shock absorption units; the pressure-relief explosion-proof unit is arranged on a spraying pipe and includes a material flow pipe, the top of the material flow pipe is in thread connection with a bolt used for pressure relief, a discharge valve is arranged at the position where the discharge hole in the bottom of the material flow pipe is fixedly connected with the spraying pipe, and a feed inlet used for connecting the spraying pipe is arranged in the position of the feed inlet of the material flow pipe. By the arrangement of the pressure-relief explosion-proof unit, high pressure in the material flow pipemakes the pressure-relief explosion-proof unit swell and burst when the pump fails and pressure of the bacterial fertilizer output to the material flow pipe is too high, high-pressure fluid in the through hole is discharged along the direction of the membrane mouth of the pressure-relief explosion-proof unit to lower the pressure in the material flow pipe, and explosion-proof performance of the device is improved.

Description

technical field [0001] The invention relates to the technical field of microbial application, in particular to a device and method for spraying bacterial fertilizer. Background technique [0002] Bacterial fertilizer, also known as biological fertilizer, biological fertilizer, bacterial fertilizer or inoculant, etc. Bacterial fertilizer, in terms of image, is "bacteria + fertilizer", because on the one hand, bacterial fertilizer contains "organic matter, nitrogen, phosphorus, potassium" and other nutrients necessary for the growth of crops, and at the same time, the product also contains a large number of beneficial microorganisms, beneficial microorganisms Bacteria reproduce in the soil and play the functions of improving soil and preventing diseases. [0003] The traditional bacterial fertilizer spraying method is manual spraying, which has low work efficiency and high labor intensity, and the existing spraying bacterial fertilizer equipment has poor explosion-proof perfo...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem of low working efficiency and high labor intensity of the existing bacterial fertilizer spraying method in the prior art, as well as poor explosion-proof performance and poor shock absorption performance of the existing spraying bacterial fertilizer equipment, the spraying equipment cannot be stably placed on the Defects on the soil surface, the present invention provides a device and method for spraying bacterial fertilizer
