Description

Technical fields:

[0002] This invention relates to the field of agricultural machinery technology, and in particular to a pesticide bottle washer. Background technology:

[0004] In agricultural planting, pesticides need to be used rationally according to the growth status, development stage, and disease situation of crops. Some bottled liquid pesticides need to be diluted with water before use. The bottle openings of the aforementioned bottled medicines are usually heat-sealed with aluminum-plastic film to ensure airtightness. When using them, the aluminum-plastic film needs to be peeled off, which is inconvenient. In addition, some pesticide liquids have high viscosity and cannot be completely poured out, resulting in a large amount of pesticide residue in the bottle. This not only causes waste, but also many pesticides are highly toxic. If they are not handled properly and are accidentally ingested by people or animals, they can easily cause accidental injury.

[0005] Existing solutions, such as the utility model patent with Chinese patent publication number CN218361173U, use a circulating pump to pressurize water and spray it into the empty bottle through a pressurized nozzle for cleaning. The above device uses diluted pesticide solution for cleaning. The advantage is that less water is used and the pesticide solution in the bottle can be cleaned at the same time as the pesticide solution is prepared. However, a certain concentration of pesticide remains in the cleaned bottle, and the cleaning is not thorough, which still poses a risk of waste and contamination of the pesticide solution. Summary of the Invention:

[0007] The purpose of this invention is to provide a pesticide bottle washer to solve the problem of insufficient cleaning of pesticide bottles in the prior art.

[0008] The present invention is implemented by the following technical solution: a pesticide bottle washing device, which includes a support frame, a double-chamber valve, a nozzle, a bottle mouth support and an opening cone. The double-chamber valve is vertically fixedly installed on the support frame. The nozzle is installed at the outlet of the valve core on the top of the double-chamber valve. The bottle mouth support is fixedly sleeved on the nozzle. The opening cone is installed on the bottle mouth support and above the nozzle.

[0009] Furthermore, the dual-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 disposed along the axis in the first inner cavity. The top surface of the first valve core is in movably sealed contact with the inlet of the second inner cavity. The bottom of the first valve core is elastically connected to the first inner cavity. A hollow push-button valve core is slidably sleeved in the second inner cavity. A sealing ring is integrally formed on the inner wall of the push-button valve core. A second valve core is fixedly disposed on the top of the first valve core. The second valve core passes through the sealing ring and is in movably sealed contact with the top surface of the sealing ring. A first spring abuts between the bottom surface of the sealing ring and the top surface of the first valve core. A stop block is integrally formed inside the push-button valve core and above the sealing ring. The stop block is in movably contacting the top surface of the second valve core. A first water inlet is opened on the side wall of the first inner cavity, and a second water inlet is opened on the side wall of the second inner cavity.

[0010] Furthermore, the first valve core is sealed to the inner wall of the first inner cavity through a sealing ring, and a push rod is integrally formed at the bottom of the first valve core. The push rod is slidably placed in the sliding sleeve at the bottom of the first inner cavity, and a second spring abuts between the push rod and the first inner cavity.

[0011] Furthermore, the elastic coefficient of the second spring is greater than that of the first spring.

[0012] Furthermore, the diameter of the second valve core is greater than the inner diameter of the sealing ring but smaller than the inner diameter of the actuated valve core.

[0013] Furthermore, the opening cone is a square pyramid shape, comprising two mutually perpendicular triangular thin plates, the base width of which is 3-5 cm.

[0014] Advantages of this invention: By incorporating a dual-chamber valve, it can switch between circulating water and clean water sources, saving water while thoroughly cleaning pesticide residue from the bottle, reducing pesticide waste and environmental pollution from residual pesticide. Furthermore, the inclusion of an opening cone facilitates pesticide preparation; simply pressing the bottle down twice completes the pouring, dilution, and cleaning of the pesticide, simplifying operation and improving the efficiency of pesticide preparation.

Detailed implementation method:

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

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

[0024] like Figure 1 As shown: A pesticide bottle washer includes a support frame 1, a dual-chamber valve 2, a nozzle 3, a bottle mouth support 4, and an opening cone 5. The dual-chamber valve 2 is vertically fixed on the support frame 1. In use, the support frame 1 is positioned at the edge of the pesticide container for easy operation. The nozzle 3 is installed at the outlet of the valve core 204 on the top of the dual-chamber valve 2. Pressing down on the valve core 204 causes water to spray out from the nozzle 3. The dual-chamber valve 2 is connected to two water sources simultaneously: one is clean water, which can be connected to tap water or other water sources used for pesticide preparation; the other is circulating water, which is connected to a circulating pump. The circulating pump draws pesticide solution from the pesticide container and sends it to the dual-chamber valve 2. The dual-chamber valve 2 can be connected to both water sources. In use, a certain amount of water is first added to the pesticide container to dilute the pesticide. The dual-chamber valve 2 first opens the circulating water to rinse the pesticide bottle, which reduces water consumption. After rinsing with circulating water, the clean water is then turned on for a more thorough rinse, completely cleaning the pesticide bottle.

[0025] A bottle neck support 4 is fixedly fitted onto the nozzle 3, and the bottle neck support 4 contacts the bottle neck. During use, the bottle to be cleaned is placed face down, with the bottle neck resting against the bottle neck support 4. Pressing down on the bottle body will simultaneously press down the push-button valve core 204. An opening cone 5 is installed on the bottle neck support 4, above the nozzle 3. Some pesticides are typically heat-sealed with an aluminum-plastic film at the bottle neck to prevent leakage during transportation. The opening cone 5 can penetrate the aluminum-plastic film, replacing manual opening and allowing for one-time opening and dispensing of the pesticide. Press to clean for easy use; the opening cone 5 is a square pyramid shape, consisting of two mutually perpendicular triangular thin plates, usually made of two isosceles triangular metal plates interlocked and welded together. The width of the base of the triangular thin plate is 3-5cm, and the specific width needs to be determined according to the diameter of the bottle mouth. It is best to choose a base width of the triangular thin plate that is smaller than the diameter of the bottle mouth, so that the opening cone 5 can 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 off during the pressing process.

[0026] like Figure 2 As shown, the dual-chamber valve 2 includes a first inner cavity 201 and a second inner cavity 202 coaxially connected to the first inner cavity 201. A first valve core 203 is slidably disposed along the axis within the first inner cavity 201. The first valve core 203 is sealed to the inner wall of the first inner cavity 201 by a sealing ring. The top surface of the first valve core 203 is in movable sealing contact with the inlet of the second inner cavity 202. The first valve core 203 is used to control the opening and closing of the first inner cavity 201 and the second inner cavity 202. The bottom of the first valve core 203 is in contact with the first inner cavity. The first valve core 203 is elastically connected to the second inner cavity 202. Specifically, the bottom of the first valve core 203 is integrally formed with a push rod 211. The push rod 211 is slidably placed in the sliding 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 subjected to external force, the first valve core 203 is pushed upward by the second spring 213 and abuts against the entrance of the second inner cavity 202. The first valve core 203 separates and seals the first inner cavity 201 and the second inner cavity 202.

[0027] A hollow push-button valve core 204 is slidably sleeved in the second inner cavity 202. Part of the push-button valve core 204 is placed inside the second inner cavity 202, and part is placed outside the second inner cavity. The inner cavity of the push-button valve core 204 communicates with the second inner cavity 202. A sealing ring 205 is integrally formed on the inner wall of the push-button valve core 204. The two sides of the sealing ring 205 respectively connect the inner cavity of the push-button valve core 204 and the second inner cavity 202. A second valve core 206 is fixedly installed on the top of the first valve core 203. The second valve core 206 passes through the sealing ring 205 and makes movable sealing contact with the top surface of the sealing ring 205. The diameter of the second valve core 206 is larger than the inner diameter of the sealing ring 205 and smaller than the inner diameter of the push-button valve core 204. At the bottom of the sealing ring 205... A first spring 207 abuts against the top surface of the first valve core 203. The elastic coefficient of the second spring 213 is greater than that of the first spring 207. When the valve core 204 is not subjected to external force, the first spring 207 lifts the valve core 204, and the sealing ring 205 contacts the second valve core 206, separating and sealing the second inner cavity 202 from the inner cavity of the valve core 204. Since the inner cavity of the valve core 204 is directly connected to the nozzle 3, the valve core 204 is in a closed state when it springs up. When the valve core 204 is pressed down, the valve core 204 compresses the first spring 207, the sealing ring 205 disengages from the second valve core 206, and the second inner cavity 202 is connected to the inner cavity of the valve core 204.

[0028] A stop block 208 is integrally formed inside the push valve core 204 and above the sealing ring 205. The stop block 208 consists of four protrusions integrally formed inside the push valve core 204. The stop block 208 is in contact with the top surface of the second valve core 206. When the push valve core 204 is pressed down a certain distance, it will contact the top surface of the second valve core 206. When the push valve core 204 is pressed down, the second valve core 206 and the first valve core 203 will be pressed down together. 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 the circulation pump and circulates circulating water to perform preliminary cleaning of the medicine bottle with diluted medicine solution. The second water inlet 210 is connected to a clean water source, which can be directly connected to tap water or other water sources used to prepare medicine solution. It does not contain medicine solution and is used to clean the medicine bottle again with clean water after the preliminary cleaning to thoroughly wash away the residual medicine solution in the medicine bottle.

[0029] like Figure 3As shown: During the initial cleaning, first align the bottle opening downwards with the opening cone 5. The opening cone 5 penetrates the sealing aluminum film at the bottle opening, and the medicine flows into the 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 sprays out from the nozzle 3. At this time, the push valve core 204 blocks the second water inlet 210 on the second inner cavity 202. All the water sprayed from the nozzle 3 is circulating water, which can save water and reduce water consumption.

[0030] like Figure 4 As shown: After rinsing with circulating water for about 5-10 seconds, some medicine residue remains in the medicine bottle due to the use of circulating water. At this time, lift the valve core 204 upwards and press it down halfway again. Since the elastic coefficient of the second spring 213 is greater than that of the first spring 207, the first spring 207 is compressed first. Until the stop block 208 just contacts the second valve core 206, you can feel the increased resistance, 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 202 are connected. 02 is sealed and blocked by the first valve core 203 and is in the 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 sequence, and is sprayed out from the nozzle 3. At this time, the sprayed water is clean water, which thoroughly cleans and replaces the medicine bottle. After two cleanings, the medicine bottle has less residual medicine, which is convenient to handle. Moreover, the overall water consumption is reduced compared to rinsing directly with clean water, which has the effect of saving water.
