Filtering device in water and fertilizer all-in-one machine

Abstract

The invention provides a filtering device in a water and fertilizer all-in-one machine. The device comprises an outer cylinder and a locking sleeve arranged at one end of the outer cylinder, a filtering assembly is arranged in the outer cylinder, and the filtering assembly is pressed and fixed on a positioning table on the inner wall of the outer cylinder by the locking sleeve. The end, different from the end connected with the outer cylinder, of the locking sleeve and the end, different from the end connected with the locking sleeve, of the outer cylinder are each provided with a connecting flange. The filtering assembly comprises a mounting frame and a filter screen which is detachably mounted on the mounting frame. The filtering device is reasonable in structural design, the filtering assembly is pressed and fixed in the outer cylinder through the locking sleeve, the fixing firmness is high, the stability is good, and the filtering assembly can be conveniently detached and cleaned. A sediment collecting hopper is arranged on the liquid flow coming side, impurities filtered in the pipeline can be removed by detaching and cleaning the sediment collecting hopper, and the pipeline is prevented from being blocked.

Description

technical field [0001] The invention belongs to the technical field of crop watering equipment, and in particular relates to a filter device in a water and fertilizer integrated machine. Background technique [0002] Water and fertilizer integration technology refers to a new agricultural technology that integrates irrigation and fertilization. The water and fertilizer integrated machine mainly uses the pressure system or the natural drop of the terrain to mix the soluble solid or liquid fertilizer according to the soil nutrient content and the law and characteristics of the fertilizer requirements of the crop species, and the fertilizer solution is mixed with the irrigation water, and the water is supplied through the pipeline system. Fertilizer is evenly and accurately delivered to the root zone of the crop. Since the flow path of the pipeline for fertilizer liquid transportation is generally small, and the fertilizer liquid usually contains impurities, biogas residues an...

AI Technical Summary

Problems solved by technology

Although there is a pipeline structure that utilizes a filter screen to filter in the prior art, the filtering effect is not good enough, the filter screen is easily blocked, and there is also the case of pipeline blockage. In this case, the filter screen needs to be cleaned frequently, and When cleaning the filter screen, it is necessary to disassemble the pipeline and take out the filter screen. The operation is cumbersome, time-consuming and laborious, and also affects the efficiency of irrigation operations.
