[0002] In greenhouse cultivation, spraying, fertilizing or watering crops (vegetables, fruits or flowers, etc.) is an important daily greenhouse management operation, which is labor-intensive. If spraying, the operator's skin will directly contact the liquid medicine, causing damage to human health. Therefore, an automatic sprayer is used to transport the liquid medicine to the sprayer for spraying. However, after conventional equipment sprays, liquid medicine often remains in the pipeline between the sprayer and the sprayer. In order to avoid corrosion of the pipeline and hinder the effect of the liquid medicine in subsequent use, farmers need to manually empty it, and the degree of automation is low. For this reason, this application provides an automatic sprayer that can solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the protection scope of the present invention.
[0019] like Figure 1 and Figure 2As shown together, the automatic pesticide sprayer includes an air compressor 21, a water pump 32 and a distribution box 12 electrically connected to the air compressor 21 and the water pump 32 installed in a casing 10. The inlet of the water pump 32 is connected to the liquid outlet of the medicine barrel 31 through a pipeline. An operating system 11 electrically connected to the distribution box 12 is provided on the surface of the casing 10. The outlets of the air compressor 21 and the water pump 32 are respectively connected to an air circuit 20 and a water circuit 30 for conveying high-pressure air and liquid medicine to the sprayer 40.
[0020] A bypass pipeline 24 is connected between the gas circuit 20 and the water circuit 30. A first solenoid valve 25 for controlling the opening and closing of the pipeline is arranged on the bypass pipeline 24. The first solenoid valve 25 is electrically connected to the control unit of the operating system 11. During the spraying process, the first solenoid valve 25 is closed, and the air and the liquid medicine are respectively delivered to the sprayer 40 through the gas circuit 20 and the water circuit 30; after the spraying is completed, the water pump 32 is closed and no longer delivers the liquid medicine, the first solenoid valve 25 is opened, and the air compressor 21 continues to work, delivering the air to the water circuit 30 through the bypass pipeline 24, so that the liquid medicine is discharged through the sprayer 40.
[0021] The operating system 11 also includes a panel with knobs and buttons, which can be used to input various control values such as spraying height and time. The control unit controls the start and stop of the air compressor 21 and the water pump 32 and the switch of the solenoid valve on the pipeline according to the state of the sprayer 40.
[0022] The bypass pipe 24 is connected to one end of the water channel 30 close to the outlet of the water pump 32 to ensure that as much liquid medicine in the water channel 30 as possible can be discharged.
[0023] like Figure 2 As shown, when the liquid medicine in the medicine barrel 31 is a mixture of medicine powder and water, the powder precipitation is prone to stratification after standing still. Therefore, in order to ensure the uniformity of the sprayed liquid medicine, in this application, it is preferred to connect a recoil pipe 26 to the outlet of the air compressor 21, and the other end of the recoil pipe 26 extends into the medicine barrel 31. The end of the recoil pipe 26 needs to extend into the bottom of the medicine barrel 31. The high-pressure air keeps the liquid medicine in motion, thereby avoiding stratification. Among them, the medicine barrel 31 is a non-sealed structure to avoid the danger of excessive air pressure in the medicine barrel 31.
[0024] The backflushing pipeline 26 is provided with a second solenoid valve 27, which is electrically connected to the control unit. When the liquid medicine in the medicine barrel 31 is a mixture of medicine powder and water, the second solenoid valve 27 is opened. When the liquid medicine in the medicine barrel 31 is a mixture of liquid medicine and water, stirring is no longer required to avoid stratification, so the second solenoid valve 27 is closed.
[0025] like Figure 1 and Figure 2As shown in the figure, an air storage tank 22 is provided between the outlet of the air compressor 21 and the gas circuit 20 to store air, reduce air flow fluctuations in the pipeline, preliminarily cool the air, and meet the need for a sudden increase in gas consumption when the sprayer 40 is started. A barometer 23 is provided on the air storage tank 22, and the barometer 23 is electrically connected to the control unit. When the gas pressure in the air storage tank 22 exceeds the limit value, the control unit cuts off the power to the air compressor 21 through the distribution box 12 to avoid danger of pipeline blockage.
[0026] like Figure 2 As shown, a pressure switch 33 is provided on the water pump 32. When the water channel 30 is blocked, resulting in excessive pressure at the outlet of the water pump 32, the pressure switch 33 controls the water pump 21 to automatically cut off the power supply, thereby ensuring the safe use of the equipment.
[0027] like Figure 1 As shown, walking wheels 13 are installed at the bottom of the housing 10 to facilitate farmers to move it.
[0028] The utility model discloses an automatic pesticide sprayer which sets a bypass pipeline between the air circuit and the water circuit, and a first solenoid valve for controlling the opening and closing of the pipeline is set on the bypass pipeline. During the pesticide spraying process, the first solenoid valve is closed. After the pesticide spraying is completed, the water pump is closed and no longer delivers liquid medicine. The first solenoid valve is opened, and the air compressor continues to work to deliver air to the water circuit through the bypass pipeline, so that the liquid medicine is discharged through the sprayer, thereby avoiding the corrosion of the pipeline by the residual liquid medicine and the influence on the subsequent use. The utility model has high autonomy and reduces the labor of farmers.
[0029] In the description of this specification, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Unless otherwise clearly defined, the terms "set", "install", "connect" and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in this utility model in combination with the specific content of the technical solution.
[0030] Although the specific implementation methods of the utility model are described above, those skilled in the art should understand that the described embodiments are only part of the implementation methods of the utility model, rather than all the implementation methods, which are only examples, and the protection scope of the utility model is defined by the claims. Those skilled in the art can make various changes or modifications to these implementation methods without departing from the principle and essence of the utility model and without any creative work, but these changes and modifications fall within the protection scope of the utility model.
