Description

Technical field:

[0001] The invention relates to the technical field of agricultural machinery, in particular to a pesticide bottle washer. Background technology:

[0002] In agricultural planting, pesticides need to be used reasonably according to the growth status, development stage and disease conditions of crops. Some bottled liquid pesticides need to be diluted with water before use; the bottle mouths of the above-mentioned bottled medicines are usually heat-sealed with aluminum-plastic film to ensure sealing. When using, the aluminum-plastic film needs to be peeled off, which is inconvenient; and some pesticide liquids have a high viscosity and cannot be completely poured out, resulting in a large amount of pesticide residue in the bottle. On the one hand, it will cause waste, and on the other hand, many pesticides are highly toxic. If they are not handled properly and are accidentally ingested by humans or animals, it is easy to cause accidental injuries.

[0003] Among the existing solutions, such as the utility model patent with Chinese patent publication number CN218361173U, water is pressurized by a circulation pump and sprayed into the empty bottle through a push-type pressure nozzle for cleaning. The above device uses diluted medicine to circulate for cleaning. The advantage is that less water is used, and the medicine in the bottle can be cleaned while preparing the medicine. However, a certain concentration of pesticides still remains in the cleaned medicine bottle. If the cleaning is not thorough, there is still a risk of waste and pollution of the medicine. Summary of the invention:

[0004] The object of the present invention is to provide a pesticide bottle washer to solve the problem of insufficient cleaning of pesticide bottles in the prior art.

[0005] The present invention is implemented by the following technical scheme: a pesticide bottle washer, which includes a support frame, a double-chamber valve, a spray head, a bottle mouth support and an unsealing cone. The double-chamber valve is vertically fixedly installed on the support frame, the spray head is installed at the outlet of the valve core at the top of the double-chamber valve, the bottle mouth support is fixedly sleeved on the spray head, and the unsealing cone is installed on the bottle mouth support and above the spray head.

[0006] Furthermore, the double-chamber valve includes a first inner cavity and a second inner cavity coaxially connected to the first inner cavity, a first valve core is slidably provided along the axis in the first inner cavity, the top surface of the first valve core is in movably sealing contact with the entrance of the second inner cavity, the bottom of the first valve core is elastically connected to the first inner cavity, a hollow push-type valve core is slidably sleeved in the second inner cavity, a sealing ring is integrally formed on the inner wall of the push-type valve core, a second valve core is fixedly provided on the top of the first valve core, the second valve core passes through the sealing ring and is in movably sealing contact with the top surface of the sealing ring, a first spring is abutted between the bottom surface of the sealing ring and the top surface of the first valve core, a stopper is integrally formed in the push-type valve core and above the sealing ring, the stopper is in movably contact with the top surface of the second valve core, a first water inlet is provided on the side wall of the first inner cavity, and a second water inlet is provided on the side wall of the second inner cavity.

[0007] Furthermore, the first valve core is sealed and connected to the inner wall of the first inner cavity via a sealing ring, a push rod is integrally formed at the bottom of the first valve core, the push rod is slidably placed in a sliding sleeve at the bottom of the first inner cavity, and a second spring is abutted between the push rod and the first inner cavity.

[0008] Furthermore, the elastic coefficient of the second spring is greater than the elastic coefficient of the first spring.

[0009] Furthermore, the diameter of the second valve core is larger than the inner diameter of the sealing ring and smaller than the inner diameter of the push valve core.

[0010] Furthermore, the unsealing cone is in the shape of a quadrangular pyramid, comprising two triangular thin sheets perpendicular to each other, and the width of the bottom side of the triangular thin sheets is 3-5 cm.

[0011] The advantages of the present invention are as follows: by providing a double-chamber valve, it is possible to switch between circulating water and clean water. While saving water, the residual liquid medicine in the medicine bottle can be thoroughly cleaned, reducing pesticide waste and environmental pollution caused by residual liquid medicine. Furthermore, an unsealing cone is provided to facilitate drug preparation. The operations of pouring, diluting and cleaning the pesticide can be completed by simply pressing the medicine bottle downwards twice.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0019] like Figure 1 As shown: a pesticide bottle washer, which includes a support frame 1, a double-chamber valve 2, a nozzle 3, a bottle mouth support 4 and an unsealing cone 5. The double-chamber valve 2 is vertically fixedly installed on the support frame 1. When in use, the support frame 1 is clamped on the edge of the medicine dispensing container for easy operation. The nozzle 3 is installed at the outlet of the pressing valve core 204 on the top of the double-chamber valve 2. When the valve core 204 is pressed down, water is sprayed out from the nozzle of the nozzle 3 through the pressing valve core 204. The double-chamber valve 2 is connected to two water sources at the same time, one is clean water, which can be connected to tap water or other water sources for preparing pesticides, and the other is circulating water, that is, it is connected to a circulating pump, and the circulating pump extracts the medicine in the medicine dispensing container and sends it into the double-chamber valve 2. The double-chamber valve 2 can be connected to the above two water sources respectively. When in use, a certain amount of water is first added to the medicine dispensing container for diluting the medicine. The double-chamber valve 2 first turns on the circulating water to rinse the medicine bottle. The circulating water can reduce the water consumption. After the circulating water is rinsed, the clean water is turned on again. The clean water rinse is more thorough and the medicine bottle can be thoroughly cleaned.

[0020] A bottle mouth support 4 is fixedly mounted on the spray head 3, and the bottle mouth support 4 is in contact with the bottle mouth. When in use, the bottle body to be cleaned is downward, and the bottle mouth abuts against the bottle mouth support 4. The bottle body can be pressed down to press the valve core 204 together. An unsealing cone 5 is installed on the bottle mouth support 4 and above the spray head 3. In order to ensure that some pesticides do not leak during transportation, a layer of aluminum-plastic film is usually heat-sealed at the bottle mouth for sealing. The unsealing cone 5 can penetrate the aluminum-plastic film to replace the manual unsealing operation, so that the bottle opening and dispensing can be completed in one go. , press to clean, easy to use; the unsealing cone 5 is a quadrangular pyramid, including two triangular thin sheets perpendicular to each other, usually made of two isosceles triangular metal sheets welded together, the bottom width of the triangular thin sheet is 3-5cm, and the specific width needs to be determined according to the diameter of the mouth of the medicine bottle. The best choice is that the bottom width of the triangular thin sheet is smaller than the diameter of the bottle mouth, which can make the unsealing cone 5 completely pierce the sealing film and make the bottle mouth firmly abut against the bottle mouth support 4, which can prevent the bottle body from sliding and falling off during the downward pressing process.

[0021] like Figure 2 As shown, the double-chamber valve 2 includes a first inner chamber 201 and a second inner chamber 202 coaxially connected to the first inner chamber 201. A first valve core 203 is slidably arranged along the axis in the first inner chamber 201. The first valve core 201 is sealed and connected to the inner wall of the first inner chamber 201 through a sealing ring. The top surface of the first valve core 203 is in active sealing contact with the inlet of the second inner chamber 202. The first valve core 203 is used to control the on-off of the first inner chamber 201 and the second inner chamber 202. The bottom of the first valve core 203 is in contact with the first inner chamber 201. 201 are elastically connected. Specifically, a push rod 211 is integrally formed at the bottom of the first valve core 201. The push rod 211 is slidably placed in a sleeve 212 at the bottom of the first inner cavity 201. A second spring 213 is abutted between the push rod 211 and the first inner cavity 201. When the first valve core 203 is not subject to external force, the first valve core 203 is lifted up by the second spring 213 and abuts against the entrance of the second inner cavity 202. The first valve core 203 separates and closes the first inner cavity 201 and the second inner cavity 202.

[0022] A hollow push valve core 204 is provided in the sliding sleeve in the second inner cavity 202. A part of the push valve core 204 is placed in the second inner cavity 202 and a part of the push valve core 204 is placed outside the second inner cavity. The inner cavity of the push valve core 204 is connected with the second inner cavity 202. A sealing ring 205 is integrally formed on the inner wall of the push valve core 204. Both sides of the sealing ring 205 are connected with the inner cavity of the push valve core 204 and the second inner cavity 202 respectively. A second valve core 206 is fixedly provided on the top of the first valve core 203. The second valve core 206 passes through the sealing ring 205 and is in active sealing contact with the top surface of the sealing ring 205. The diameter of the second valve core 206 is larger than the inner hole diameter of the sealing ring 205 and smaller than the inner diameter of the push valve core 204. At the bottom of the sealing ring 205, a sealing ring 205 is formed on the inner wall of the push valve core 204. A first spring 207 is in contact between the surface and the top surface of the first valve core 203, and the elastic coefficient of the second spring 213 is greater than the elastic coefficient of the first spring 207. When the push valve core 204 is not subjected to external force, the first spring 207 lifts the push valve core 204, and the sealing ring 205 contacts the second valve core 206, separating and sealing the second inner cavity 202 and the inner cavity of the push valve core 204. Since the inner cavity of the push valve core 204 is directly connected to the nozzle 3, the push valve core 204 is in a closed state when it pops up. When the push valve core 204 is pressed down, the push valve core 204 compresses the first spring 207, the sealing ring 205 separates from the second valve core 206, and the second inner cavity 202 is connected to the inner cavity of the push valve core 204.

[0023] A stopper 208 is integrally formed inside the push valve core 204 and above the sealing ring 205. The stopper 208 is four protrusions integrally formed inside the push valve core 204. The stopper 208 is in active contact with the top surface of the second valve core 206. After pressing the push valve core 204 for a distance, it will contact the top surface of the second valve core 206. Continuing to press the push valve core 204 will press down together with the second valve core 206 and the first valve core 203. A first water inlet 209 is provided on the side wall of the first inner cavity 201, and a second water inlet 210 is provided on the side wall of the second inner cavity 202; the first water inlet 209 is connected to a circulation pump to pass circulating water, which is used to perform preliminary cleaning of the medicine bottle with the diluted medicine liquid; the second water inlet 210 is connected to a clean water source, which can be directly connected to tap water or other water sources for configuring medicine liquid, does not contain medicine liquid, and is used for cleaning again with clean water after preliminary cleaning, so that the residual medicine liquid in the medicine bottle can be thoroughly cleaned.

[0024] like Figure 3As shown: during the initial cleaning, the bottle mouth is first aligned downward with the unsealing cone 5, and the unsealing cone 5 penetrates the sealing aluminum film of the bottle mouth, and the liquid medicine is left in the medicine dispensing container below. At this time, the push valve core 204 needs to be fully pressed down, and the first valve core 203 is also pressed down at the same time. When the position of the first valve core 203 is lower than the first water inlet 209, the circulating water enters the first inner cavity 201, the second inner cavity 202 and the inner cavity of the push valve core 204 in sequence, and is sprayed out from the nozzle 3. At this time, the second water inlet 210 on the second inner cavity 202 is blocked by pressing the valve core 204, and the nozzle 3 sprays out the circulating water, which can save water resources and reduce water consumption;

[0025] like Figure 4 As shown: Use circulating water to clean for about 5-10 seconds. Since the medicine bottle is cleaned with circulating water, there is still a certain amount of medicine liquid left. At this time, press the valve core 204 upward and lift it up. Press it halfway again. Since the elastic coefficient of the second spring 213 is greater than the elastic coefficient of the first spring 207, the first spring 207 is compressed first until the stopper 208 just contacts the second valve core 206. The resistance can be felt to increase, which proves that the second valve core 206 has been opened, but the first valve core 203 has not been opened. At this time, the first inner cavity 201 and the second inner cavity 203 are closed. 02 is sealed and blocked by the first valve core 203 and is in a closed state. The second valve core 206 and the sealing ring 205 are separated from the second inner cavity 202 and connected to the inner cavity of the push valve core 204. Clean water passes through the second water inlet 210, the second inner cavity, the sealing ring 205 and the inner cavity of the push valve core 204 in turn, and is sprayed out from the nozzle 3. At this time, clean water is sprayed out, which thoroughly cleans and replaces the medicine bottle. After two cleanings, there is less residual medicine in the medicine bottle, which is convenient for handling. In addition, the overall water consumption is reduced compared to directly flushing with clean water, which has a water-saving effect.
