An inspection port 5 is provided on the front of the cover body 3, and one end of the inspection port 5 passes through and extends to the front inner wall of the cover body 3. A symmetrically distributed fixed block 6 is fixedly connected to the front of the cover body 3, and a rotating shaft 7 is installed on the inner wall of the two fixed blocks 6 through a bearing. A cover plate 8 is fixedly sleeved on the outer surface of the rotating shaft 7, and a handle 9 is fixedly connected to the upper surface of the cover plate 8. When the reciprocating paint sprayer body 2 is working normally, the cover plate 8 covers the inspection port 5 to prevent the spread of toxic gases and harmful substances in the cover body 3;

[0026] A torsion spring 10 is fixedly connected to one side surface of the fixed block 6, and one end of the torsion spring 10 is fixedly connected to one side surface of the cover plate 8. The setting of the torsion spring 10 makes the lower surface of the cover plate 8 fit tightly with the front surface of the cover body 3, preventing the toxic gas and harmful substances in the cover body 3 from spreading.

[0027] Furthermore, the two side surfaces of the cover plate 8 are fixedly connected with symmetrically distributed support blocks 11, and the lower surface of the support block 11 is provided with a support groove 12. The setting of the support groove 12 enables the cover plate 8 to be supported when the reciprocating paint sprayer body 2 is repaired or maintained.

[0028] Furthermore, the front of the cover body 3 is provided with symmetrically distributed storage grooves 13, and the inner wall of one side of the storage groove 13 is hinged with a support rod 14 through a pin shaft. The outer surface of one end of the support rod 14 contacts the inner wall of the support groove 12. The support rod 14 and the support groove 12 cooperate with each other, so that the cover plate 8 is firmly supported.

[0029] Furthermore, an exhaust port 15 is provided on the back of the cover body 3, one end of the exhaust port 15 passes through and extends to the rear inner wall of the cover body 3, and an exhaust fan 16 is fixedly installed on the inner wall of the exhaust port 15. The air volume of the exhaust fan 16 is controllable, and the harmful gases and harmful substances in the cover body 3 are gathered and discharged through the exhaust port 15 without affecting the normal operation of the compound paint sprayer body.

[0030] Furthermore, a bell tube 17 is fixedly connected to the back of the cover body 3 , and one end of the bell tube 17 is fixedly connected to one end of the exhaust port 15 , and the exhaust port 15 discharges harmful gases and harmful substances into the bell tube 17 .

[0031] Furthermore, the other end of the trumpet tube 17 is fixedly connected to a connecting pipe 18, one end of the connecting pipe 18 is fixedly connected to a recovery and purification box 19, the lower surface of the recovery and purification box 19 is fixedly connected to the upper surface of the base 1, and one side surface of the recovery and purification box 19 is fixedly connected to an exhaust pipe 20. The harmful gases and harmful substances in the cover body 3 are gathered and enter the recovery and purification box 19 through the exhaust port 15 and the connecting pipe 18, and are purified by the purification device in the recovery and purification box 19, and are discharged from the exhaust pipe 20 after being detected and confirmed to be harmless by the detection device.

[0032] Furthermore, the lower surface of the base 1 is fixedly connected to support legs 21 distributed in a rectangular array, and the upper surface of the base 1 is provided with a feeding device 22, which feeds the material to be painted into the reciprocating paint spraying machine body 2 for painting.

[0033] The provision of inspection ports and covers makes it very convenient to repair or maintain the reciprocating paint sprayer. The provision of exhaust ports and exhaust fans can effectively prevent harmful gases and substances from diffusing from the inlets and outlets, thereby reducing the chances of operators inhaling harmful gases and coming into contact with harmful substances and reducing the risk of occupational diseases.

[0034] Working principle: Step 1. When the reciprocating paint sprayer body 2 is working normally, the cover plate 8 is in the state of covering the inspection port 5. The reciprocating paint sprayer body 2 includes a horizontal slide rail, a longitudinal slide rail and a vertical telescopic rod, which can be moved in three-dimensional space. When the reciprocating paint sprayer body starts spraying paint, the exhaust fan 16 is turned on. The air volume of the exhaust fan 16 is controllable. Without affecting the normal operation of the reciprocating paint sprayer body, the harmful gases and harmful substances in the cover body 3 are gathered and enter the recovery purification box 19 through the exhaust port and the connecting pipe 18. After being purified by the purification device in the recovery purification box 19, they are discharged from the exhaust pipe 20 after being detected and confirmed to be harmless by the detection device.

[0035] Step 2: When the reciprocating paint sprayer body 2 fails or needs maintenance, grab the handle 9 and lift it. The handle 9 drives the cover plate 8 to open and expose the inspection port 5. At the same time, the handle 9 drives the rotating shaft 7 to rotate through the cover plate 8. The handle 9 also drives the torsion spring 10 to rotate through the cover plate 8. When the cover plate 8 is lifted to a horizontal state, the support rod 14 in the storage groove 13 is lifted, and the outer surface of one end of the support rod 14 is fitted with the inner wall of the support groove 12, thereby supporting the cover plate 8. At this time, The inspection port 5 is used to repair or maintain the reciprocating paint sprayer body 2. When the repair or maintenance is completed, the handle 9 is slightly lifted upward again. The handle 9 drives the cover plate 8 to slightly lift upward so that the outer surface of one end of the support rod 14 is no longer in contact with the inner wall of the support groove 12. The support rod 14 rotates downward under the action of gravity and enters the storage groove 13. At this time, the handle 9 is released, and the cover plate 8 rotates downward and fits the front of the cover body 3 under the action of the torsion spring 10 to cover the inspection port 5. At this time, normal work can be carried out.
