The water inlet of the oil circuit block is connected to the water outlet of the water pump 50 through a connecting pipe. The liquid outlets of all solenoid valves are connected to the water inlet connection ends of the corresponding three-way connectors through connecting pipes.

[0055] Furthermore, the top surface from the edge to the middle of the bottom plate of the water storage tank 10 is an inclined surface inclined obliquely toward the middle, and a bottom discharge connector 15 is screwed into the screw-through hole in the middle of the bottom plate of the water storage tank 10, and the bottom end of the bottom discharge connector 15 extends out of the bottom surface of the bottom plate of the water storage tank 10. The bottom discharge connector 15 is usually a screw plug, and after a certain period of use, it can be disassembled to directly discharge the water and sediment at the bottom of the water storage tank 10. When discharging, the filter screen plate 13 can be taken out, and the sediment adhering to the bottom plate of the water storage tank 10 can be manually washed to achieve discharge and cleaning, which is very convenient.

[0056] Furthermore, side vertical baffles 131 are fixed to the bottom surfaces of the left and right sides of the filter screen plate 13, and the outer side walls of the side vertical baffles 131 are close to the inner side walls of the corresponding side baffles 12;

All drainage connectors 61 are connected to one end of the corresponding drainage connecting pipes, and the other ends of all drainage connecting pipes are connected to the corresponding water inlet of the water collector and distributor. The water outlet of the water collector and distributor is connected to the water inlet of the second delivery pump 2 through a connecting pipe, and the water outlet of the second delivery pump 2 is connected to the second water inlet connector 16 through a connecting pipe ( Figure 1 In the figure, the water collector and the second delivery pump are shown as simple diagrams. Figure 1 Only the internal material trough body 60 is shown, so only two inlets of the manifold are connected. In actual use, all inlets are connected to corresponding connecting pipes connected to the drainage connector 61 of the internal material trough body 60).

[0060] A stepped through hole 62 extending downward is formed on the top middle surface of the bottom plate of the inner material receiving trough body 60, and a drainage connector 61 is welded and fixed to the middle of the bottom surface of the bottom plate of the inner material receiving trough body 60, and the drainage connector 61 is communicated with the stepped through hole 62;

The filter sleeve 64 is stuck in the small diameter hole section.

[0062] The above structure allows part of the water sprayed from the water spray hole 1 or the water during rain to enter the inner material receiving tank body 60 to store water. After the water is filtered by the filter sleeve 64, it is operated by the second delivery pump to enter the water storage tank 10 through the second water inlet connector 16. During the long-term spraying state, the second delivery pump is operated to ensure continuous delivery. It is necessary to ensure that the water in the inner material receiving tank body 60 during spraying is basically in a balanced state, that is, the water in the inner material receiving tank body 60 cannot be too low to cause the second delivery pump to run idle. After 15 minutes of operation, this embodiment can basically ensure that the water in the inner material receiving tank body 60 is in a normal state. Of course, a liquid level sensor can also be installed in the inner material receiving tank body 60, which can be electrically connected to the control host through an electrical connection line. The control host always obtains the sensing signal of the liquid level sensor. When it senses that the water level is lower than the lowest water level, the control host controls the second delivery pump to stop running. When there is no spraying, the second delivery pump does not run either.

[0063] Furthermore, a slot portion 21 is fixed to the bottom of the outer wall of each adjacent side of two protective enclosures 20, and a vertical baffle 22 is inserted into the two slot portions 21 and covers the gap between the two adjacent protective enclosures 20.

The left end of the internal cavity of the protective shell 70 extends out of the left side wall of the protective shell 70 and communicates with the corresponding side through hole.

[0070] The protective shell 70 can perform secondary filtration on the water entering the middle water outlet connector 11 to improve the filtering effect, and it only needs to pull out the middle blocking bar 74 (which is a metal part, the surface of which is coated with anti-rust paint and other materials, and it is placed by its own weight) to remove the protective shell 70 for cleaning, maintenance and repair, which is very convenient.
