Description

Technical Field

[0001] This utility model relates to the field of spray device technology, and in particular to an automatic drug supply device and an automatic drug dosing spray system. Background Technology

[0002] Agricultural sprinklers are widely used in greening applications such as lawns and tree spraying in parks, factories, schools, and residential areas, as well as in farmland and orchards. However, current sprinkler systems often only spray water for irrigation based on soil moisture levels. When applying pesticides or liquid fertilizers, people need to carry sprayers to apply them. Obviously, spraying and pesticide application are carried out separately and require manual labor. For large areas of farmland and green spaces, spraying pesticides or applying liquid fertilizers requires a lot of manpower and resources, which is time-consuming and labor-intensive. Utility Model Content

[0003] Therefore, it is necessary to provide an automatic pesticide dispensing equipment and an automatic pesticide spraying system that can improve the spraying efficiency of pesticides and liquid fertilizers and reduce labor and time costs.

[0004] An automatic drug dispensing device, comprising:

[0005] The housing contains an electrical control mounting cavity, a mixing cavity, a reagent containing cavity, and a water pump mounting cavity.

[0006] The water inlet assembly is equipped with a solenoid valve, one end of which is connected to the mixing chamber, and the other end extends to the outside of the housing and is used to connect to the water source.

[0007] A medicine storage container is placed inside the medicine receiving cavity;

[0008] A dosing pipe equipped with a drug pump is connected at both ends to the drug storage container and the drug mixing chamber, respectively.

[0009] A spray pump is installed inside the pump mounting cavity; one end of the spray pump is connected to the mixing chamber, and the other end is used to connect to the spray pipeline set in farmland, green area or orchard.

[0010] A control device is installed inside the electrical control mounting cavity; the control device is electrically connected to the solenoid valve, the drug pump, and the spray water pump respectively; the control device is used to control the spray water pump to work within a preset spray time period, and also to control the solenoid valve and the drug pump to work according to a preset time sequence, so as to add a preset proportion of water and medicine into the mixing chamber.

[0011] An automatic pesticide spraying system includes an automatic pesticide supply device as described above and a spraying pipeline arranged in farmland, green areas or orchards; the outlet of the spraying water pump is connected to the spraying pipeline.

[0012] The aforementioned automatic pesticide supply equipment and automatic pesticide spraying system, through a control device, automatically adds pesticides and water into the mixing chamber and mixes them thoroughly to obtain a mixed pesticide solution. The control device also controls the spray pump to pump the mixed pesticide solution into spray pipes located in farmland, green areas, or orchards at set times, thus achieving timed spraying of these areas. This utilizes the spray pipes to effectively improve the efficiency of pesticide spraying, reduce manual labor input, and lower labor and time costs. Furthermore, integrating all components, including the water inlet assembly, pesticide storage container, pesticide pump, spray pump, and control device, into the casing not only makes the automatic pesticide supply equipment more compact but also facilitates its relocation. This allows the automatic pesticide supply equipment to selectively pump mixed pesticide solution to different locations in the spray pipes as needed, effectively reducing the equipment cost for pesticide spraying.

[0022] Appendix Figure 1 and Figure 2 The diagram illustrates the structure of an automatic drug dispensing device according to one embodiment of the present invention. For ease of explanation, the accompanying drawings only show structures relevant to embodiments of the present invention.

[0023] Please see Figure 1 This utility model provides an automatic pesticide supply device 100 and an automatic pesticide spraying system. The automatic pesticide spraying system includes the automatic pesticide supply device 100 and a spraying pipeline 30 arranged in farmland, green areas, or orchards. The automatic pesticide supply device 100 is connected to the spraying pipeline 30 and is used to pump the pre-mixed pesticide solution into the spraying pipeline 30, so that the spraying pipeline 30 can spray the mixed pesticide solution to one or more locations in the farmland, green areas, or orchards through one or more nozzles.

[0024] Please refer to the following: Figure 2 The automatic drug supply device 100 in the preferred embodiment of this utility model includes a housing 110, a water inlet assembly 120, a drug storage container 130, a drug dosing pipe 140, a spray water pump 150, and a control device 160.

[0025] The interior of the housing 110 has an electrical control mounting cavity 111, a mixing cavity 112, a drug containing cavity 113, and a water pump mounting cavity 114.

[0026] The water inlet assembly 120 is equipped with a solenoid valve (not shown in the figure). One end of the water inlet assembly 120 is connected to the mixing chamber 112, and the other end extends to the outside of the housing 110 and is used to connect to a water source. The water source can be municipal tap water, water stored in a water storage container, or water from nearby rivers, ponds, streams, reservoirs, wells, or other natural sources.

[0027] The medicine storage container 130 is placed inside the medicine receiving cavity 113. The medicine storage container 130 is used to store medicines. In actual use, medicines can be replenished or added to the automatic medicine dispensing device 100 by removing or placing the medicine storage container 130 into the medicine receiving cavity 113.

[0028] A drug pump 170 is installed on the drug dosing pipe 140. The two ends of the drug dosing pipe 140 are connected to the drug storage container 130 and the drug mixing chamber 112, respectively.

[0029] A spray pump 150 is installed inside a pump mounting cavity 114. One end of the spray pump 150 is connected to a mixing chamber 112, and the other end is used to connect to a spray pipe 30 installed in farmland, green areas, or orchards. In an automatic spray system, the other end of the spray pump 150 can be connected to the spray pipe 30 installed in farmland, green areas, or orchards.

[0030] The control device 160 is installed in the electrical control mounting cavity 111. The control device 160 is electrically connected to the solenoid valve, the chemical pump 170, and the spray water pump 150. The control device 160 is used to control the spray water pump 150 to work within a preset spraying time period, and also to control the solenoid valve and the chemical pump 170 to work according to a preset sequence to add a preset ratio of water and chemical agent into the mixing chamber 112.

[0031] In practical applications, when it is necessary to mix the medicine in the mixing chamber 112, the staff connects one end of the water inlet component 120 to the water source, puts the medicine storage container 130 containing sufficient medicine into the medicine receiving chamber 113, and then starts the automatic medicine supply equipment 100. At this time, the control device 160 controls the operation of the solenoid valve and the medicine pump 170 respectively to add water and medicine in a preset ratio into the mixing chamber 112.

[0032] When it is necessary to use an automatic pesticide spraying system to spray pesticides on farmland, green areas, or orchards, the outlet of the spray pump 150 is connected to the spray pipeline 30 arranged in the farmland, green area, or orchard, and the automatic pesticide supply equipment 100 is started. The control device 160 controls the spray pump 150 to operate within a preset time period (e.g., from 6 pm to 8 pm every day, or from 5 pm to 9 pm every day, or a certain time period every few days, etc.) to pump the mixed solution in the mixing chamber 112 to the spray pipeline 30, and spray the mixed pesticide solution onto the farmland, green area, or orchard through the spray pipeline 30 to achieve the purpose of timed pesticide spraying.

[0033] The aforementioned automatic pesticide supply equipment 100 and automatic pesticide spraying system, through the control device 160, automatically add pesticides and water into the mixing chamber 112 and mix them evenly to obtain a mixed pesticide solution. The control device 160 also controls the spraying water pump 150 to pump the mixed pesticide solution into the spraying pipeline 30 arranged in farmland, green areas, or orchards at regular intervals, thereby realizing the timed spraying of farmland, green areas, or orchards. The spraying pipeline 30 is used to spray the pesticide solution, which effectively improves the spraying efficiency of agricultural pesticide solution, reduces the manual input in the spraying process, and reduces labor and time costs. In addition, all components such as the water inlet assembly 120, the pesticide storage container 130, the pesticide pump 170, the spray water pump 150, and the control device 160 are integrated on the housing 110. This not only makes the structure of the automatic pesticide supply equipment 100 more compact, but also facilitates the relocation of the automatic pesticide supply equipment 100. This allows the automatic pesticide supply equipment 100 to select different locations of the spray pipes 30 to pump mixed pesticide solution according to actual needs, effectively reducing the equipment cost of agricultural pesticide spraying.

[0034] Please refer to the following: Figure 3 and Figure 4 In some embodiments, the housing 110 includes a housing 115. A first partition 116, a second partition 117, and a third partition 118 are arranged crosswise inside the housing 115 to divide the space inside the housing 115 into an electrical control mounting cavity 111, a mixing cavity 112, a drug containing cavity 113, a component mounting cavity 119, and a water pump mounting cavity 114.

[0035] The water inlet assembly 120 includes an inlet pipe 121 and a filter 122 disposed on the inlet pipe 121. One end of the inlet pipe 121 communicates with the mixing chamber 112, and the other end extends to the outside of the housing 115 and is used to connect to a water source. The filter 122 and the pump 170 are both installed in the component mounting cavity 119. Thus, a solenoid valve is disposed on the inlet pipe 121 to control the opening and closing of the inlet pipe 121.

[0036] Thus, by setting the first partition 116, the second partition 117 and the third partition 118 in a cross pattern within the housing 115, independent electrical control mounting chamber 111, mixing chamber 112, drug containing chamber 113, component mounting chamber 119 and water pump mounting chamber 114 are formed within the housing 115, so as to separate the control device 160, the mixed drug solution, the drug storage container 130, the drug pump 170, the filter 122 and the spray water pump 150, and avoid affecting their respective working performance.

[0037] The filter 122 is installed to filter and purify the water in the inlet pipe 121 to ensure that clean water is added to the mixing chamber 112, thereby extending the service life of the spray pump 150 and the spray pipeline 30 and reducing maintenance costs.

[0038] Furthermore, in some embodiments, the sidewalls of the housing 115 are respectively formed with a first opening (not shown) communicating with the electrical control mounting cavity 111, a second opening (not shown) communicating with the agent containing cavity 113, a third opening (not shown) communicating with the component mounting cavity 119, and a fourth opening (not shown) communicating with the water pump mounting cavity 114.

[0039] The housing 110 also includes a first door 1101, a second door 1102, a third door 1103, and a fourth door 1104. The first door 1101 is installed at the first opening and is capable of opening or closing the first opening. The second door 1102 is installed at the second opening and is capable of opening or closing the second opening. The third door 1103 is installed at the third opening and is capable of opening or closing the third opening. The fourth door 1104 is installed at the fourth opening and is capable of opening or closing the fourth opening.

[0040] The first door 1101 allows staff to easily check the operating parameters of the automatic drug dispensing equipment 100 by opening the first switch, and to interact with the control device 160 to modify or adjust certain parameters. For example, by changing the opening time of the drug pump 170 and the solenoid valve, the ratio of water to medicine added to the mixing chamber 112 can be adjusted. The second door 1102 allows staff to easily access the storage container 130 through the second opening, facilitating the addition and replenishment of medicine. The third door 1103 and the fourth door 1104 allow staff to easily check the status of the drug pump 170, filter 122, and spray pump 150 through the third and fourth openings, improving maintenance convenience.

[0041] When the first door 1101, the second door 1102, the third door 1103, and the fourth door 1104 are closed, it can prevent external mud, sand, water, debris, dust in the air, etc. from entering the electrical control installation cavity 111, the medicine container cavity 113, the component installation cavity 119, and the water pump installation cavity 114. This can protect the control device 160, the medicine storage container 130, the medicine pump 170, the filter 122, and the spray water pump 150, and further extend their service life.

[0042] Of course, in other embodiments, only one or more of the first door body 1101, the second door body 1102, the third door body 1103 and the fourth door body 1104 may be set, or none of the doors may be set.

[0043] Furthermore, in some embodiments, the first partition 116 is arranged laterally, such that the electrical control mounting cavity 111, the mixing cavity 112, and the component mounting cavity 119 are all located on the upper side of the first partition 116, while the water pump mounting cavity 114 and the agent storage cavity 113 are all located on the lower side of the first partition 116. The first partition 116 has an outlet (not shown) connecting the mixing cavity 112 and the water pump mounting cavity 114. One end of the spray pump 150 is connected to the outlet.

[0044] Thus, the electrical control mounting cavity 111, the mixing cavity 112, and the component mounting cavity 119 form one group, and the agent containing cavity 113 and the water pump mounting cavity 114 form another group. The two groups are distributed vertically within the housing 115. This not only facilitates operation of the control device 160 by the staff, but also makes it easier for the staff to put the agent containing container 130 into the agent containing cavity 113, as the agent containing container 130 is relatively heavy. At the same time, the mixed liquid in the mixing cavity 112 can enter the spray water pump 150 under its own gravity, which facilitates the start-up of the spray water pump 150.

[0045] Furthermore, in some embodiments, the second partition 117 is vertically arranged, such that the electrical control mounting cavity 111 and the reagent receiving cavity 113 are located on one side of the second partition 117, and the mixing cavity 112, the component mounting cavity 119, and the water pump mounting cavity 114 are located on the other side of the second partition 117. The third partition 118 is located above the first partition 116 and is vertically arranged between the mixing cavity 112 and the component mounting cavity 119. The end of the third partition 118 away from the first partition 116 has a water inlet mounting hole (not shown) and a dosing mounting hole (not shown). The water inlet pipe 121 passes through the water inlet mounting hole, and one end extends into the top of the mixing cavity 112. The dosing pipe 140 passes through the dosing mounting hole, one end is equipped with a check valve 180 and extends into the bottom of the mixing cavity 112.

[0046] Thus, the electrical control mounting cavity 111 and the reagent containing cavity 113 form one group, while the mixing cavity 112, the component mounting cavity 119, and the water pump mounting cavity 114 form another group. These two groups are located on the left and right sides of the second partition 117, respectively. The third partition 118 is located above the water pump mounting cavity 114. Therefore, both the mixing cavity 112 and the component mounting cavity 119 are located above the water pump mounting cavity 114. This not only facilitates the entry of the mixed liquid in the mixing cavity 112 into the spray pump 150, but also shortens the length of the inlet pipe 121 while protecting the filter 122 and the pump 170, making the automatic drug supply device 100 more compact. Furthermore, an inlet mounting hole and a dosing mounting hole are provided at the top of the third partition 118 to prevent leakage of liquid from the mixing cavity 112 through these holes. In addition, the opening of the water inlet pipe 121 in the mixing chamber 112 is set at the top of the mixing chamber 112, and the end of the dosing pipe 140 equipped with the check valve 180 is set at the bottom of the mixing chamber 112 to improve the mixing effect of the medicine and water in the mixing chamber 112.

[0047] Specifically, the opening of one end of the water inlet pipe 121 inside the mixing chamber 112 faces the direction of the first partition 116. That is, the opening of one end of the water inlet pipe 121 inside the mixing chamber 112 faces downward, so as to avoid the water flowing out of the water inlet pipe 121 impacting the inner wall of the mixing chamber 112, which helps to extend the service life of the housing 110 and improve the operational stability of the automatic drug supply equipment 100.

[0048] In some embodiments, the bottom end of the mixing chamber 112 is provided with a drain port (not shown) communicating with the outside. A drain pipe 190 is installed at the drain port. A control valve 201 is provided on the drain pipe 190. In actual use, it is inevitable that different liquids will be sprayed or that spraying will not be required for a long time. At this time, simply opening the control valve 201 will allow the residual mixed liquid in the mixing chamber 112 to be discharged through the drain port and the drain pipe 190. When it is necessary to clean the mixing chamber 112, the wastewater can also be discharged from the mixing chamber 112 through the drain port by opening the control valve 201. Therefore, the provision of the drain port, the drain pipe 190, and the control valve 201 further improves the ease of use of the automatic drug dispensing equipment 100 and effectively extends the service life of the automatic drug dispensing equipment 100.

[0049] Specifically, the first partition 116 has a first outlet (not shown) communicating with the mixing chamber 112. The side wall of the housing 115 has a second outlet (not shown) serving as a drain. A drain pipe 190 passes through the second outlet, with one end communicating with the first outlet and the other end located outside the housing 115 and equipped with a control valve 201. Thus, the first outlet is located on the bottom wall inside the mixing chamber 112, and the section of the drain pipe 190 between the first and second outlets is a bend, ensuring that residual liquid or wastewater from cleaning in the mixing chamber 112 can be completely drained through the drain pipe, effectively reducing the residue of medicine or cleaning solution in the mixing chamber 112.

[0050] Of course, in other embodiments, the drain outlet can be located on the side wall at the bottom of the mixing chamber 112, as long as the function of draining the liquid in the mixing chamber 112 can be achieved.

[0051] In some embodiments, the inner wall of the mixing chamber 112 is provided with an overflow port 1105 communicating with the outside. The overflow port 1105 is located at the top of the mixing chamber 112. The overflow port 1105 is provided so that when the automatic drug supply device 100 malfunctions and cannot close the solenoid valve and the drug pump 170 in time, the liquid in the mixing chamber 112 can be discharged through the overflow port 1105, thereby reducing the probability of the automatic drug supply device 100 malfunctioning.

[0052] In some embodiments, the automatic drug dispensing device 100 further includes a first liquid level detection element 202 and a second liquid level detection element 203. The first liquid level detection element 202 is communicatively connected to the control device 160 and is used to trigger a switch signal when the liquid level in the mixing chamber 112 reaches a preset high liquid level. The second liquid level detection element 203 is communicatively connected to the control device 160 and is used to trigger a switch signal when the liquid level in the mixing chamber 112 reaches a preset low liquid level. The control device 160 is used to control the solenoid valve and the drug pump 170 to close when it receives the switch signal from the first liquid level detection element 202, and is also used to control the spray water pump 150 to close when it receives the switch signal from the second liquid level detection element 203.

[0053] Thus, during the mixing process, the first liquid level detector 202 detects the liquid level in the mixing chamber 112 and immediately sends a trigger signal to the control device 160 when the liquid level reaches the preset high level. At this time, the control device 160 immediately controls the solenoid valve and the drug pump 170 to close, thereby stopping the addition of water and drugs to the mixing chamber 112 and improving the safety of the automatic drug supply equipment 100. During the drug spraying process, when the second liquid level detector 203 detects that the liquid level of the mixed drug in the mixing chamber 112 has dropped to the preset low level, it immediately sends a trigger signal to the control device 160. At this time, the control device 160 immediately controls the spray pump 150 to stop working, thereby stopping the drug spraying operation and preventing damage to the spray pump 150 due to dry running, effectively extending the service life of the spray pump 150.

[0054] In some embodiments, the bottom of the housing 110 is provided with a plurality of movable and fixed casters 204. The movable and fixed casters 204 are used to facilitate the automatic drug dispensing device 100's flexible movement on the travel surface during short-distance transfers, and also to prevent the automatic drug dispensing device 100 from continuing to move when it stops, ensuring the safety of the automatic drug dispensing device 100. Therefore, the aforementioned movable and fixed casters 204 facilitate convenient short-distance movement of the automatic drug dispensing device 100 while also ensuring its safety.

[0055] Specifically, the movable fixed caster 204 includes a wheel frame 2041 mounted on the bottom of the housing 115, a roller 2042 mounted on the wheel frame 2041, and a support foot 2043 mounted on the wheel frame 2041. The support foot 2043 is operably extendable and retractable relative to the wheel frame 2041 in the vertical direction. More specifically, one end of the support foot 2043 is provided with an external thread, and the wheel frame 2041 has a threaded hole. The threaded end of the support foot 2043 is screwed into the threaded hole. In actual use, the extension and retraction of the support foot 2043 relative to the wheel frame 2041 can be achieved by rotating the caster. Of course, in other embodiments, the extension and retraction of the support foot 2043 relative to the wheel frame 2041 can also be achieved by setting multiple connection points and a locking structure.

[0056] When the automatic drug dispensing device 100 needs to move a short distance, the support foot 2043 can be raised to facilitate the movement of the automatic drug dispensing device 100 by the roller 2042; after the automatic drug dispensing device 100 has moved into place, the support foot 2043 can be lowered to abut against the ground to support the housing 110 and prevent the roller 2042 from continuing to move the housing 110.

[0057] In other embodiments, the movable fixed casters may also be movable casters with brakes, or other structures that can ensure both flexible movement and continued movement of the organization after the automatic drug dispensing equipment has been moved into place.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
