the third mounting rack 4c3, the third mounting rack 4c3 and the third frame 4c1 are fixedly mounted, the third mounting rack 4c3 is fixedly mounted at the side of the third frame 4c1, the middle part of the third mounting rack 4c3 is also fixedly mounted with a fourth filter screen 4c4, a rectangular cavity is formed between the third filter screen 4c2 and the fourth filter screen 4c4 through the third mounting rack 4c3, and an active filter bag is placed in the rectangular cavity and used for filtering impurities, heavy metals and the like in water;

a plurality of fourth sliding chutes 4c6, wherein the fourth sliding chutes 4c6 are provided, the fourth sliding chutes 4c6 are respectively arranged in the rack 1 in a vertical state, and two sides of the third frame 4c1 are slidably connected with the fourth sliding chutes 4c 6;

the third handle 4c5, the third handle 4c5 and the second frame 4b1 are fixedly arranged, and the third handle 4c5 is fixedly arranged at the top end of the second frame 4b 1.

The irrigation water filtered by the first filtering device 4a in the working state has no foreign matters basically, and finally impurities in the water are filtered and removed by an activated carbon bag arranged between the third filter screen 4c2 and the fourth filter screen 4c4 through a rectangular cavity formed by the third mounting rack 4c3 and then are transmitted towards the adsorption and removal device 5.

Referring to fig. 9, the adsorption cleaning device 5 includes:

the pesticide adsorption device comprises a water flow tank 5a, wherein the water flow tank 5a is horizontally arranged inside the rack 1 along the long side direction of the rack 1, the water flow tank 5a is arranged at the outlet end of the rack 1, a snake-shaped groove 5b is further formed in the surface of the water flow tank 5a from top to bottom, and a pesticide adsorption component 5e which is vertically arranged is further fixedly arranged at each corner of the snake-shaped groove 5 b;

the first opening 5c is formed in one end of the snake-shaped groove 5b, and the first opening 5c is used for water inflow;

and the second opening 5d is arranged at the other end far away from the first opening 5c, and the second opening 5d is used for discharging water.

Inside irrigation water after filter device 4 filters got into snakelike recess 5b by first opening 5c under operating condition, the water source transmits to second opening 5d along with snakelike recess 5b, carry out final absorption in the farmland of discharging through the pesticide adsorption component 5e that sets up in every corner of snakelike recess 5b to the pesticide residue in the aquatic etc. at the in-process of transmission, inside snakelike recess 5b can make its water source stop to flow water tank 5a with longer time, filtering through a plurality of pesticide adsorption component 5 e.

Referring to fig. 10, the pesticide adsorption assembly 5e includes:

the placing barrel 5e1 is arranged, the placing barrel 5e1 is arranged in a vertical state, and the placing barrel 5e1 is fixedly arranged at a plurality of corners of the snake-shaped groove 5 b;

cartridge 5e2, cartridge 5e2 being placed inside the containment tub 5e 1;

a fixing cover 5e3, a fixing cover 5e3 is detachably mounted on the top end of the placing barrel 5e 1.

When the filter element 5e2 needs to be replaced in the working state, a worker unscrews the fixing cover 5e3, takes out the filter element 5e2 placed in the placing barrel 5e1, and replaces the filter element, and screws the filter element 5e2 after replacement is finished.

The working principle of the invention is as follows:

the method comprises the following steps: in the working state, a worker firstly places the equipment to a water source access port of a farmland to be irrigated, the inlet end of the rack 1 is arranged towards the water source access port, the outlet end of the rack 1 is arranged towards the farmland, the rack 1 is fixed through the fixing device 2, and then the flow blocking device 3 is started to enable the irrigation water source to flow into the rack 1;

step two: the filtering device 4 is used for carrying out multi-stage filtration on the irrigation water source which is flooded, filtering foreign matters such as residual branches, plastic bags, weeds, films and the like in the water and outputting the filtered foreign matters to the adsorption and removal device 5;

step three: the adsorption and removal device 5 is used for adsorbing and filtering pesticide residues, heavy metals and the like in the filtered irrigation water and finally discharging the pesticide residues, the heavy metals and the like into a farmland.

The foregoing has described the general principles, principal features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
