Spraying device applicable to installation of plastic runway

Abstract

The invention discloses a spraying device applicable to installation of a plastic runway. The spraying device comprises a bottom plate, wherein four sleeves are uniformly arranged at the upper part ofthe outer side of a hopper; an inserting rod is arranged in each sleeve; a fixed block is arranged at the upper end of each inserting rod; a dustproof net is commonly arranged among the four fixed blocks; mounting grooves are symmetrically arranged at the outer side of each inserting rod; a resetting spring is arranged in each mounting groove; a limiting block matched with each mounting groove isarranged at one end of each resetting spring; a discharging pipe connected with an air compressor is arranged at the bottom end of the hopper; a solenoid valve and an adjusting valve are arranged atthe outer side of the discharging pipe respectively. According to the spraying device disclosed by the invention, the outer side of the dustproof net is connected with the inserting rods through the fixed blocks, and the resetting springs and the limiting blocks are arranged at the outer sides of the inserting rods, so that the inserting rods inserted into the sleeves are convenient to fix and thespraying device is convenient to mount and dismount and is convenient to clean.

Description

technical field [0001] The invention belongs to the technical field of spraying equipment, and in particular relates to a spraying device suitable for installing a plastic runway. Background technique [0002] Plastic track, also known as all-weather track and field track, is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to athletes' speed and technical performance, effectively improving sports performance and reducing the rate of falls. The plastic runway is composed of polyurethane rubber and other materials. It has certain elasticity and color, and has certain anti-ultraviolet ability and aging resistance. It is internationally recognized as the best all-weather outdoor sports floor material. Now the cou...

Problems solved by technology

[0004] The purpose of the present invention is to provide a spraying device suitable for the installation of plastic runway, to solve the above-mentioned background technology, the hopper of the existing sprayer for plastic runway is generally open, so it is necessary to set a dust-proof net to prevent dust from polluting the spraying material , but it is inconvenient to disassemble and clean the dust-proof net; in addition, during the long-term spraying process, the sprayed material will continue to settle at the bottom of the hopper, resulting in uneven spraying and poor spraying effect; and the sprayed material will be in the discharge of the hopper Accumulation occurs at the mouth, which affects the discharge of the sprayer; in addition, the push rod structure of the sprayer is relatively fixed, and the height cannot be adjusted according to the height of the user, which is difficult to meet the comfort of different people
