Description

Technical Field

[0001] The utility model relates to the field of supporting equipment for spray machines, in particular to an open flame protection cover for a spray machine. Background Art

[0002] Sprayers generally refer to mechanical equipment for agricultural and forestry plant protection, which are widely used in the fields of insecticide, disinfection or fertilization. Existing sprayers are mainly divided into flame mist machines and steam sprayers. Flame mist machines mix the agent and auxiliary agent and then heat them for spraying. However, the agent is easily decomposed when heated at high temperature, which affects the efficacy of the agent. Steam sprayers separate the agent and auxiliary agent and heat the auxiliary agent separately, and then mix the agent at room temperature with the auxiliary agent heated at high temperature and spray them to ensure the medicinal properties of the agent. In addition, steam sprayers have the advantages of smaller size and lighter weight than flame mist machines.

[0003] Existing sprayers will generate exhaust gas and smoke during the heating and combustion process, so the sprayers are required to have a smoke exhaust port. However, when the working time is too long, open flames will appear at the smoke exhaust port of the sprayer. The open flames will produce a lot of noise, which will pose a safety hazard during use and affect the user experience of the staff. If the user touches it by mistake, burns will occur.

[0018] Example: Figures 1 to 4As shown, a flame resistant cover for a sprayer includes a heater 5, the heater 5 is fixedly connected to a heating sleeve 1, a heat dissipation sleeve 2 is sleeved on the outside of the heating sleeve 1, one end of the heat dissipation sleeve 2 is fixedly connected to the outside of the heating sleeve 1, a flame resistant assembly 3 is sleeved on the outside of the heating sleeve 1, the flame resistant assembly 3 includes a top mounting plate 31, an inner sleeve mounting tube 32 and an outer sleeve fire resistant cover 34 are fixedly connected to the lower surface of the top mounting plate 31, and a flame resistant chamber 36 is formed between the inner sleeve mounting tube 32 and the outer sleeve fire resistant cover 34. The flame resistant chamber 36 can be set to reflux and extinguish the flame generated by excessive temperature, which can eliminate the flame on the one hand and prevent the potential safety hazard caused by the flame on the other hand.

[0019] The inner sleeve mounting tube 32 is provided with a plurality of inner sleeve smoke exhaust ports 33, and the outer sleeve fireproof cover 34 is provided with a plurality of outer sleeve smoke exhaust ports 35, and the plurality of inner sleeve smoke exhaust ports 33 are connected with the plurality of outer sleeve smoke exhaust ports 35 through the open flame prevention cavity 36. Through the provided outer sleeve smoke exhaust ports 35, the generated smoke can be effectively discharged without affecting the gas flow of the smoke in the open flame prevention cavity 36, and the influence of the open flame itself can be eliminated under the premise of achieving normal exhaust of the smoke.

[0020] The end of the outer jacket fireproof cover 34 away from the top mounting plate 31 is fixedly connected to a limit stop ring 37, and the limit stop ring 37 is cooperatively connected with the heat dissipation sleeve 2. The limit stop ring 37 can support the open flame protection component 3, and the inner ring of the limit stop ring 37 is arranged in close contact with the heating sleeve 1, thereby preventing smoke from leaking from the limit stop ring 37.

[0021] The top mounting plate 31 is provided with a medicine discharge pipe opening 6 and two heating pipe openings 7 on its upper surface. A heating coil 4 is sleeved in the heating sleeve 1. The heating coil 4 is respectively provided through the medicine discharge pipe opening 6 and the two heating pipe openings 7. The heating coil 4 can be limited and fixed by the medicine discharge pipe opening 6 and the two heating pipe openings 7 to ensure the stability of the heating coil 4.

[0022] The output end of the heating coil 4 is fixedly connected with a spray nozzle 9, and the side of the spray nozzle 9 is fixedly connected with a drug delivery tube 8. The drug delivery tube 8 can deliver the drug liquid to the spray nozzle 9, and then spray the drug liquid during the high-pressure auxiliary agent spraying process to achieve a spray effect.

[0023] Working principle: the exhaust gas generated by the heater 5 during the combustion process is discharged through the inner sleeve exhaust port 33, and the exhaust gas passes through the anti-open flame cavity 36 and then is discharged through the outer sleeve exhaust port 35 to realize the discharge of the exhaust gas. After a long period of continuous operation, an open flame is generated at the inner sleeve exhaust port 33, and the open flame enters the anti-open flame cavity 36 driven by the flow of exhaust gas. The open flame forms a bending track in the anti-open flame cavity 36, causing the open flame to no longer continue to extend outward, so that the open flame will not be discharged from the outer sleeve exhaust port 35, thereby achieving the anti-open flame effect, preventing safety hazards, and ensuring the safety of operators.
