[0002] Pesticide spraying is an important technology used to prevent and control pests and diseases in agricultural production. It involves spraying pesticides onto crops or harmful organisms through specific equipment to achieve the purpose of controlling pests and diseases and protecting crop growth. Pesticide spraying is not just a simple spraying of the liquid pesticide, but a complex process involving multiple links and technical points. Correct pesticide spraying can effectively control pests and diseases, while inappropriate use may lead to reduced efficacy, increased costs and environmental pollution.

[0003] In the prior art, when spraying pesticides, operators generally use sprayers to spray manually. Since the sprayed pesticides will fly in the air, in order to protect the operators from the harmful effects of the pesticides, the operators often wear protective masks for protection. However, when spraying pesticides outdoors, the operators will produce a lot of sweat. Due to the high outdoor temperature, sweat or impurities may adhere to the inside of the protective mask, causing the protective mask to become blurred, affecting the operator's observation of the pesticide spraying.

The operator controls the micro-stepping motor 71. At this time, the micro-stepping motor 71 can drive the gear 72 to rotate. Since the gear 72 and the ring gear 73 are meshed with each other, the mounting frame 74 can move along the surface of the ring gear 73. At the same time, the scraper 75 can move along the guide groove 8. When the scraper 75 moves from one side to the other, the scraper 75 can scrape off the sweat and impurities adhered to the protective mask 3, so as to avoid the operator from being affected by the mist or impurities when using the protective mask. The operator can use the card block 4 and the card hole 5 on the elastic adjustment plate 6 to adjust the connection position between the elastic adjustment plate 6, so as to adapt to the head circumference of different users and increase its applicability. When the operator wears the protective mask 3, an elastic sponge pad is arranged in the protective frame 2, which can increase the comfort of the protective mask 3 and avoid long-term wearing, which causes discomfort and affects the user experience.

[0024] A quick disassembly assembly 9 is provided in the middle of the support frame 1. The quick disassembly assembly 9 is used to install the protective mask 3. The quick disassembly assembly 9 includes a plurality of limit blocks 91. The limit blocks 91 are evenly distributed and fixedly installed on the upper part of the protective mask 3 close to the support frame 1. A notch 97 is provided in the middle of the bottom end of the limit block 91. A plurality of evenly distributed cavities 95 are provided in the middle of the support frame 1. A plurality of evenly distributed springs 93 are fixedly installed in each cavity 95. Abutment plates 94 are fixedly installed on the top of the same group of springs 93. A push rod 92 is fixedly installed on the top of the push rod 92 and the push rod 92 passes through the upper part of the support frame 1. A plurality of evenly distributed limit grooves 96 are provided on the side of the support frame 1 close to the protective mask 3 and the limit grooves 96 They are respectively connected to the cavities 95 on the same side, and the upper limit block 91 of the protective mask 3 is inserted into the limit groove 96. At this time, the wedge-shaped surface of the lower part of the limit block 91 can contact the wedge-shaped surface of the abutment plate 94. As the limit block 91 moves, the abutment plate 94 will move downward in the cavity 95, and the spring 93 will be compressed. When the abutment plate 94 moves to the lower part of the notch 97, the spring 93 will clamp the abutment plate 94 in the notch 97, thereby completing the installation of the protective mask 3, and the operator can push the push rod 92 to move downward. At this time, the push rod 92 will push the abutment plate 94 downward, so that the limit block 91 will lose the restriction of the abutment plate 94, making it easy to operate and take it out, so that the support frame 1 can be separated from the protective mask 3, which is convenient for boxing.

[0025] In actual use, the operator inserts the limit block 91 on the protective mask 3 into the limit groove 96. At this time, the abutment plate 94 cooperates with the spring 93 and the notch 97 to limit and fix the limit block 91, that is, the combined installation of the protective mask 3 is completed, and then the protective mask 3 can be worn using the clamping hole 5 and the clamping block 4 on the elastic adjustment plate 6. After wearing, the operator can implement pesticide spraying. Since pesticide spraying is generally carried out outdoors, if the weather is hot, sweat or impurities will adhere to the inside of the protective mask 3. At this time, by controlling the micro-stepping motor 71, the micro-stepping motor 71 cooperates with the ring gear 73, the gear 72, the mounting frame 74 and the guide groove 8, the scraper 75 can be moved, so that the sweat and impurities in the protective mask 3 can be cleaned, thereby ensuring that the operator's vision will not be affected, and it is convenient to observe the pesticide spraying situation.

[0026] Although the above describes the illustrative specific implementation methods of the present application so that technicians in this technical field can understand the present application, the present application is not limited to the scope of the specific implementation methods. For ordinary technicians in this technical field, as long as various changes are within the spirit and scope of the present application defined and determined by the attached claims, all application creations using the concept of the present application are protected.
