Among them, the storage battery 11 can provide power for this device to ensure that the water pump 801 can operate. Through the spraying assembly 2, spraying operations around can be carried out. The spraying range and intensity can be adjusted by using the spraying assembly 2, so that this device effectively solves the problem that when manually spraying, due to the need for personnel to adjust the spraying position by themselves and the spraying range is small during a single spraying, the overall spraying efficiency is not high and the required time also increases accordingly. Then, the spraying effect is greatly enhanced and the spraying duration is reduced. Among them, by cooperating this assembly with the universal wheels 6, the device can move during the continuous spraying process. Therefore, compared with the existing spraying devices in greenhouses, it can carry out rapid spraying operations without additional setting of a site, effectively solving the problem that the spraying efficiency is relatively average in large areas, and then strengthening the adaptability of this device.

[0036] In this embodiment, the spraying assembly 2 includes a component main board 201. Lateral sliding blocks 2012 are respectively arranged on both side surfaces of the component main board 201. A sliding mounting seat 2013 is fixedly installed on the surface of the component main board 201. An I-shaped slider 2021 is fixedly arranged inside the sliding mounting seat 2013. An adjustment housing 202 is slidably arranged inside the sliding mounting seat 2013.

[0037] Among them, a pre-storage tank 2018 is opened inside the adjustment housing 202. T-shaped chutes 2017 are respectively opened on both sides of the inner wall of the pre-storage tank 2018. T-shaped sliders 2015 are respectively slidably arranged in the two T-shaped chutes 2017. A sealing slider 2016 is integrally arranged between the two T-shaped sliders 2015. A through hole penetrates through the middle of the sealing slider 2016.

A water outlet baffle 2027 is integrally arranged on one side inside the pre-storage tank 2018. A plurality of nozzles are arranged on the body of the water outlet baffle 2027. The liquid is transferred to the sealing slider 2016 through the connecting hose 16, and the liquid is transferred to the pre-storage tank 2018 by using the through hole penetrating through the middle of the sealing slider 2016 and then sprayed externally in cooperation with the nozzles. Among them, by using the cooperation between the sealing slider 2016 and the T-shaped slider 2015 and the T-shaped chute 2017, the adjustment of the current spraying intensity can be adjusted, effectively controlling the amount of the internal liquid flowing out from the nozzles arranged on the body of the water outlet baffle 2027, so that it can match different spraying requirements. When adjusting the internal intensity, the adjustment can be achieved by pulling the connecting hose 16.

[0038] It should be noted that a mating slide bar 2022 is integrally provided on the back surface of the adjustment housing 202. Each mating slide bar 2022 is slidably mated with the side of the I-shaped slider 2021. A number of positioning teeth 2023 are integrally provided on the surface of each mating slide bar 2022. A number of derivative through holes 2024 are respectively formed on both sides of the I-shaped slider 2021. A limiting spring 2025 is fixedly installed inside each derivative through hole 2024. A positioning rack 2026 is commonly installed at the end of each limiting spring 2025 on each side. Each positioning rack 2026 is engaged with the positioning teeth 2023 on the corresponding side. Through the support and limitation of the positioning rack 2026 by the limiting spring 2025, each positioning rack 2026 can always be engaged with the positioning teeth 2023 on the corresponding side, so as to realize the positioning operation of the current height when adjusting the height of the adjustment housing 202, ensuring that it is more stable during spraying.

[0039] It can be understood that in the present application, mating through holes 2014 are respectively formed on the lower surface of the component main board 201. An adjusting screw rod 803 and an auxiliary limiting rod 804 are respectively rotatably installed on the inner wall of each side positioning groove 8 near the mating through hole 2014. Each auxiliary limiting rod 804 is sleeved and mated with the mating through hole 2014. Each adjusting screw rod 803 is threadedly mated with the mating through hole 2014. Sliding installation grooves 802 are respectively formed on both sides of the inner wall of each side positioning groove 8. The inside of each sliding installation groove 802 is slidably mated with the corresponding side sliding block 2012. A sealing connection pipe 805 is fixedly installed at the water inlet end of each water pump 801. Each sealing connection pipe 805 is hermetically penetrated inside the medicine storage tank 12. By using the adjusting screw rod 803 and its threaded mating with the mating through hole 2014, the position of the component main board 201 can be adjusted to be pulled out or combined inward under the limitation of the sliding installation groove 802, so as to facilitate the personnel to store the spraying component 2 in the later stage and effectively reduce its occupied space.

[0040] When specifically set, the feeding assembly 3 includes a sealing plate 3012. The sealing plate 3012 is integrally arranged on the upper surface of the chemical storage tank 12 located between the two turning plates 7. A through extending branch pipe 3011 is arranged in the middle of the sealing plate 3012. An upper end of the extending branch pipe 3011 is integrally provided with a feeding funnel 301. A bearing seat 302 is fixedly installed at the bottom of the chemical storage tank 12 on one side of the extending branch pipe 3011. A driving rod 3021 is rotatably installed above the bearing seat 302. A plurality of driving vanes 3023 are integrally arranged on the rod body of the driving rod 3021 located inside the extending branch pipe 3011. A stirring fan blade 3022 is integrally arranged on the rod body of the driving rod 3021 located inside the chemical storage tank 12. By using the feeding funnel 301 to receive chemicals, the internal chemicals can be transferred into the extending branch pipe 3011. Among them, the driving vanes 3023 arranged inside the extending branch pipe 3011 cooperate with the falling force when the chemicals fall to realize the rotation of the rod body of the driving rod 3021, so that the stirring fan blade 3022 performs an auxiliary stirring operation on the internal chemicals.

[0041] Among them, two universal wheels 6 are respectively and fixedly installed on the lower surface of the device housing 1 on the side far from the spraying assembly 2. Rotating mounting seats 601 are respectively and fixedly installed on the lower surface of the device housing 1 on the side close to the spraying assembly 2. A rotating mounting rod 602 is rotatably installed between the two rotating mounting seats 601. A pressing roller 603 is fixedly installed on the rod body of the rotating mounting rod 602. A matching slot 15 is penetrated and opened on the surface of the device housing 1 close to the equipment installation slot 10. A protection plug board 13 is inserted into the matching slot 15. By inserting the protection plug board 13 into the matching slot 15, the equipment installation slot 10 can be closed to reduce the influence of the external environment on the internal equipment. And by fixedly installing the pressing roller 603 on the rod body of the rotating mounting rod 602, the current road surface can be assisted in being flattened to avoid tilting during placement due to the unevenness of the current road surface, effectively improving its stability.

[0042] The working principle of the agricultural spraying device for agricultural machinery:

[0043] During use, first fill the chemicals into the feeding funnel 301. Subsequently, the driving vanes 3023 arranged inside the extending branch pipe 3011 cooperate with the falling force when the chemicals fall to realize the rotation of the rod body of the driving rod 3021, so that the stirring fan blade 3022 performs an auxiliary stirring operation on the internal chemicals. After the feeding is completed, start the PCB control board 9 to control the start and stop of the battery 11 for the water pump 801. By starting the water pump 801, the materials inside the chemical storage tank 12 are transferred into the connecting hose 16 through the sealed connecting pipe 805;

[0044] Subsequently, the liquid is transferred to the sealed slider 2016 through the connecting hose 16, and the liquid is transferred into the pre-storage tank 2018 by means of a through hole penetrating through the middle of the sealed slider 2016 and then sprayed externally through a nozzle. During use, the height of the sealed slider 2016 in the pre-storage tank 2018 can be adjusted by pulling the connecting hose 16, thereby adjusting the internal spraying intensity. Among them, by adjusting the height of the adjustment housing 202, the current spraying range can be adjusted.

[0045] It should be noted that the specific model specifications of the storage battery 11, the water pump 801, and the PCB control board 9 are determined according to actual usage requirements.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
