Spraying device of scraper loader

Abstract

The invention provides a spraying device of a scraper loader. The spraying device of the scraper loader comprises a fixedly mounted liquid injection gun; a linkage pull rod is arranged on the liquid injection gun; the linkage pull rod uses a journey control rod and is connected with a handle switch of the liquid injection gun; the journey control rod comprises a stretchable turnbuckle; and one end of the turnbuckle is connected with the linkage pull rod, and the other end of the turnbuckle is connected with the handle switch. The spraying device of the scraper loader provided by the invention has the advantages of flexible and reliable connection, simplicity and convenience in operation, uniform material, high durability, large water outlet pressure, and enough water flow; the better effect of the dust prevention can be realized; the health of staff operation can be ensured; and the working efficiency of the safe operation can be improved.

Description

technical field [0001] The invention relates to mining equipment, in particular to a rake machine spraying device. Background technique [0002] At present, the current use of the rake machine spray linkage device is to use 10 thick long steel plates with a length of 35 cm and a width of 4 cm. A plurality of connecting wire eyes with unequal distances are drilled on the steel plate, and 10 wire holes fixed on the rake machine beam are used. Two cut-off valves are connected together. Due to the wear of the gate skin during use, the stroke of the cut-off valve is large (the opening and closing strokes are 90 degrees), and the stroke operation gap of the main and auxiliary roller mechanisms is different, resulting in inflexible spray linkage of the rake machine and small water flow. , Insufficient water pressure, can not achieve a good effect of spraying and dust suppression, which will have adverse effects on the health of employees. Contents of the invention [0003] The t...

[0002] At present, the current use of the rake machine spray linkage device is to use 10 thick long steel plates with a length of 35 cm and a width of 4 cm. A plurality of connecting wire eyes with unequal distances are drilled on the steel plate, and 10 wire holes fixed on the cross beam of the rake machine are used. Two cut-off valves are connected together. Due to the wear of the gate skin during use, the stroke of the cut-off valve is large (the opening and closing strokes are 90 degrees), and the stroke operation gap of the main and auxiliary roller mechanisms is different, resulting in inflexible spray linkage of the rake machine and small water flow. , the water pressure is insufficient, and the effect of spraying and dust suppression cannot be achieved, which will adversely affect the health of employees
