Description

Technical Field

[0001] This utility model belongs to the field of sampling technology, specifically a biological pesticide sampling device. Background Technology

[0002] Biopesticides are preparations that utilize living organisms (fungi, bacteria, insect viruses, genetically modified organisms, natural enemies, etc.) or their metabolites (pheromones, auxins, sodium naphthaleneacetate, 2,4-D, etc.) to kill or inhibit agricultural pests. Also known as natural pesticides, they are non-chemically synthesized, derived from natural chemical substances or living organisms, and possess the effects of fungicides and insecticides. Sampling is required during the production of biopesticides for testing purposes.

[0003] Currently, the operating principle of biopesticide sampling equipment is mainly based on the precise collection, storage, and analysis of biopesticides.

[0004] In existing technologies, most biological pesticides are sampled using syringes. However, a small amount of pesticide residue remains inside the syringe, which can affect subsequent testing or use. Therefore, a biological pesticide sampling device is proposed to address this problem. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a biological pesticide sampling device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A biological pesticide sampling device of this utility model includes a cylindrical body; a push handle is slidably connected to the bottom of the cylindrical body, and a push rod is fixedly connected to the top of the push handle; a valve cylinder is connected to the bottom of the cylindrical body; an inlet is connected to one side of the valve cylinder, and an outlet is connected to the other side of the valve cylinder; a ball valve is rotatably connected to the middle of the valve cylinder; a through hole is opened in the middle of the ball valve, and a waterproof and breathable membrane is fixedly connected to the top of the through hole; during operation, firstly, the push rod is pushed into the cylindrical body, keeping the push handle at the bottom of the cylindrical body; then, the ball valve is rotated to keep the through hole and the valve cylinder horizontal; then, the inlet port is inserted into the biological pesticide storage tank, and the outlet port is placed into the sampling bottle; then, the push rod is pulled out to... Pulling the pusher upwards creates negative pressure inside the cylinder, drawing up the biological pesticide. The pesticide solution passes sequentially through the inlet, valve cylinder, through-hole, and outlet before entering the sampling bottle. During this process, a waterproof and breathable membrane prevents the pesticide solution from entering the cylinder, ensuring smooth passage through the through-hole. Based on the graduations on the outer surface of the cylinder corresponding to the pusher, quantitative pesticide dispensing is achieved. After sampling, pushing the pusher back compresses the air inside the cylinder, expelling any remaining pesticide solution from the valve cylinder, inlet, outlet, and through-hole. By incorporating the through-hole and waterproof and breathable membrane, the system ensures the pesticide solution enters the outlet smoothly without passing through the cylinder, while also allowing for quantitative dispensing based on the pusher's upward movement, reducing pesticide residue and minimizing inaccurate dispensing.

[0007] Preferably, the push handle is fixedly connected to both sides of the page edge, and two telescopic rods are fixedly connected to one end of the page edge. A locking block is fixedly connected to one end of each telescopic rod. During operation, the locking block can be hung on both sides of the biological pesticide storage tank. The telescopic rods can adjust the spacing of the locking blocks according to the size of different storage tanks. This simplifies the sampling operation, eliminates the need to hold the cylinder by hand, and reduces the likelihood of the cylinder shaking, which could lead to accidents during the sampling process.

[0008] Preferably, one end of the liquid inlet is provided with a telescopic needle tube, which is connected to the liquid inlet. During operation, the telescopic needle tube can be extended to facilitate sampling work in storage tanks with small amounts of biological pesticides.

[0009] Preferably, a sealing ring is fixedly connected to the top of the push handle. The sealing ring is correspondingly set to the cylinder body. During operation, the push handle slides inside the cylinder body. In order to ensure more accurate quantitative sampling, the sealing ring fits against the inner side of the cylinder body and fills the gap between the cylinder body and the push handle to ensure airtightness.

[0010] Preferably, a pad is provided on one side of the card block, and the pad is fixedly connected to the card block. During operation, the card block is in direct contact with the biological pesticide storage tank, and collision damage is inevitable. The pad protects the storage tank.

[0011] Preferably, the push rod is provided with multiple abrasive strips on its outer side. The abrasive strips are fixedly connected to the push rod. During operation, the abrasive strips increase the friction of the push rod and reduce the occurrence of slippage.

[0012] The beneficial effects of this utility model are:

[0013] This utility model provides a biological pesticide sampling device. By setting through holes and a waterproof and breathable membrane, it ensures that the pesticide solution does not pass through the cylinder and enters the outlet smoothly. At the same time, it can quantitatively extract the pesticide solution according to the height of the push handle, reducing the phenomenon of inaccurate pesticide solution extraction caused by pesticide residue.

[0014] This invention provides a biological pesticide sampling device. The spacing of the clamps can be adjusted according to the size of different storage tanks using a telescopic rod. This simplifies the sampling operation, eliminates the need to manually hold the cylinder, and reduces cylinder shaking, which could lead to accidents during the sampling process.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific examples are given below.

[0026] Please see Figure 1 - Figure 5 This utility model provides a biological pesticide sampling device, including a cylindrical body 1; a push handle 11 is slidably connected to the bottom of the cylindrical body 1, and a push rod 12 is fixedly connected to the top of the push handle 11. A valve cylinder 13 is connected to the bottom of the cylindrical body 1, with an inlet 14 connected to one side of the valve cylinder 13 and an outlet 15 connected to the other side. A ball valve 16 is rotatably connected to the middle of the valve cylinder 13, and a through hole 17 is opened in the middle of the ball valve 16. A waterproof and breathable membrane 18 is fixedly connected to the top of the through hole 17. During operation, the push rod 12 is first pushed into the cylindrical body 1, keeping the push handle 11 at the bottom of the cylindrical body 1. Then, the ball valve 16 is rotated to keep the through hole 17 and the valve cylinder 13 horizontal. The inlet 14 is then inserted into the biological pesticide storage tank, and the outlet 15 is placed into the sampling bottle. Finally, the push rod 12 is pulled out, pushing the push handle 11 upward. Pulling the tube creates negative pressure inside the cylinder 1, drawing up the biological pesticide. The pesticide solution passes sequentially through the inlet 14, valve cylinder 13, through-hole 17, and outlet 15, before entering the sampling bottle. During this process, the waterproof and breathable membrane 18 prevents the pesticide solution from entering the cylinder 1, ensuring that the solution passes smoothly through the through-hole 17. Based on the scale on the outer surface of the cylinder 1 corresponding to the push handle 11, quantitative liquid extraction can be achieved. After sampling, pushing the push rod 12 back compresses the air inside the cylinder 1, expelling any residual pesticide solution from the valve cylinder 13, inlet 14, outlet 15, and through-hole 17. By setting the through-hole 17 and the waterproof and breathable membrane 18, the solution is ensured to enter the outlet 15 smoothly without passing through the cylinder 1, while quantitative liquid extraction can be performed based on the height of the push handle 11, reducing the possibility of inaccurate liquid extraction due to pesticide residue.

[0027] Furthermore, such as Figure 1 and Figure 4 As shown, the push handle 11 is fixedly connected to the two sides of the page edge 2. Two telescopic rods 21 are fixedly connected to one end of the page edge 2. A locking block 22 is fixedly connected to one end of the telescopic rod 21. During operation, the locking block 22 can be hung on both sides of the biological pesticide storage tank. The telescopic rod 21 can adjust the spacing of the locking block 22 according to the size of different storage tanks. This makes the sampling operation simple, eliminates the need to hold the cylinder 1 by hand, and reduces the shaking of the cylinder 1, which could lead to accidents during the sampling process.

[0028] Furthermore, such as Figure 1 As shown, one end of the liquid inlet 14 is provided with a telescopic needle tube 3, which is connected to the liquid inlet 14. During operation, the telescopic needle tube 3 can be stretched and extended to facilitate sampling work in storage tanks with small amounts of biological pesticides.

[0029] Furthermore, such as Figure 5 As shown, a sealing ring 4 is fixedly connected to the top of the push handle 11. The sealing ring 4 is correspondingly set with the cylinder 1. During operation, the push handle 11 slides inside the cylinder 1. In order to ensure more accurate quantitative sampling, the sealing ring 4 fits against the inner side of the cylinder 1 and fills the gap between the cylinder 1 and the push handle 11 to ensure airtightness.

[0030] Furthermore, such as Figure 4 As shown, a pad 5 is provided on one side of the card block 22. The pad 5 is fixedly connected to the card block 22. During operation, the card block 22 is in direct contact with the biological pesticide storage tank, and collision damage is inevitable. The pad 5 protects the storage tank.

[0031] Furthermore, such as Figure 5 As shown, the push rod 12 is provided with multiple abrasive strips 6 on its outer side. The abrasive strips 6 are fixedly connected to the push rod 12. During operation, the abrasive strips 6 increase the friction of the push rod 12 and reduce the occurrence of slippage.

[0032] Working principle: First, push the push rod 12 into the cylinder 1, keeping the push handle 11 at the bottom of the cylinder 1. Then, rotate the ball valve 16 to keep the through hole 17 horizontal with the valve cylinder 13. Next, insert the inlet port 14 into the biological pesticide storage tank and the outlet port 15 into the sampling bottle. Then, pull the push rod 12 to pull the push handle 11 upward, creating a negative pressure inside the cylinder 1, which will draw the biological pesticide up. The pesticide solution passes sequentially through the inlet port 14, the valve cylinder 13, the through hole 17, and the outlet port 15. The sample is then inserted into the sampling bottle. During this process, the waterproof and breathable membrane 18 prevents the liquid from entering the cylinder 1, ensuring that the liquid passes smoothly through the through hole 17. According to the scale on the outer surface of the cylinder 1 corresponding to the push handle 11, a quantitative liquid sampling effect can be achieved. After sampling is completed, the push rod 12 is pushed back to compress the air in the cylinder 1, which can discharge the residual liquid in the valve cylinder 13, the inlet 14, the outlet 15, and the through hole 17. By setting the through hole 17 and the waterproof and breathable membrane 18, the liquid is kept in a safe and stable state. The system ensures that the pesticide solution enters the outlet 15 smoothly without passing through the cylinder 1, while also allowing for quantitative sampling based on the height of the push handle 11. This reduces pesticide residue and inaccurate sampling. The locking blocks 22 can be hung on both sides of the biological pesticide storage tank. The telescopic rod 21 can adjust the spacing of the locking blocks 22 according to the size of different storage tanks, simplifying the sampling operation. It eliminates the need to manually hold the cylinder 1, reducing the likelihood of the cylinder 1 shaking and causing accidents during sampling. The telescopic needle 3 can be extended to handle sampling from storage tanks with smaller biological pesticide reserves. The push handle 11 slides inside the cylinder 1. To ensure more accurate quantitative sampling, the sealing ring 4 fits against the inside of the cylinder 1, filling the gap between the cylinder 1 and the push handle 11 to ensure airtightness. The locking blocks 22 are in direct contact with the biological pesticide storage tank, which may inevitably cause collision damage. The pad 5 protects the storage tank, and the frosted strip 6 increases the friction of the push rod 12, reducing slippage.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
