Filtering device used for gardening maintenance watering carts

Abstract

The invention belongs to the technical field of filtering, and especially relates to a filtering device used for gardening maintenance watering carts. According to the filtering device, the lower endof an upper housing is arranged on the upper surface of a lower housing through clamping, and pre-fastening is realized using a first bolt; a second filter screen is arranged in the lower part of thelower housing; the two ends of the second filter screen are fixedly provided with position limiting plates; one end of each position limiting plate is designed to penetrate through the lower housing and stretch outside the lower housing; a position limiting mechanism is used for position limiting; sealing rings are arranged on the external surfaces of the position limiting plates; a filtering mechanism is arranged in the lower housing above the second filter screen; an annular blocking plate matching the lower housing is fixedly arranged in the lower housing above the filtering mechanism; a plurality of position limiting columns are arranged on the upper part of the annular blocking plate; a first filter screen is arranged on the annular blocking plate; and the first filter screen is connected with the position limiting columns through clamping. The filtering device can be dismounted for cleaning of the internal part, so that the service life of the filtering device is prolonged.

Description

technical field [0001] The invention relates to the technical field of filtering, in particular to a filtering device for a greening maintenance sprinkler. Background technique [0002] As the saying goes, "Three points of planting, seven points of cultivation", if the maintenance work is not done well, the garden landscape built at a high cost will not be well maintained, and some grasslands will soon degrade, trees will die, and weeds will overgrow. Therefore, landscape maintenance should implement scientific and standardized scientific maintenance management. The so-called green maintenance refers to the management and maintenance of green land, vegetation and other plants. It is still a new industry. Due to the particularity of the industry, it is being recognized by the society, and three levels of maintenance management standards have been established. The main contents of greening maintenance include: watering, fertilizing, pruning, weeding, green space cleaning, pes...

AI Technical Summary

Problems solved by technology

When greening and maintaining, the most important thing is watering. Since the greening water is basically directly extracted from the river, it is necessary to filter the river water. The filtering device in the prior art can only be used for simple filtering. After that, the filter device is easy to block, so the filtration efficiency is low
