Description

Technical Field

[0001] The invention relates to the technical field of quantitative proportioning devices, in particular to a quantitative proportioning device for forestry pesticide application. Background Art

[0002] Pine wilt disease, a devastating forest disease caused by the pine wood nematode, is known as the "cancer of pine trees." It spreads rapidly, has a high mortality rate, and is difficult to control. Glucohexaose is an oligosaccharide product. Its oligosaccharide chains often serve as recognition sites for receptors and enzymes. They covalently link to proteins to form one or more glycoproteins. The sugar chains within glycoproteins vary widely and contain rich structural information, effectively altering protein structure and potentially changing the activity of some proteins.

[0003] The use of glucan hexaose to control pine wood nematodes works by inhibiting pathogenic proteins, exopolysaccharides, peptides, and other pathogenic factors on the surface of the pine wood nematode through covalent bonding. It also activates the pine tree's immune system to regulate plant life, enhance photosynthesis, and improve disease and stress resistance. This activates and enhances the pine tree's self-immunity, allowing the nematode to survive without the tree dying, forming a symbiotic biological chain.

[0004] In the prior art, dextran and corresponding insecticides are mixed with strong permeation and transport aids to prepare a pine wood nematode control solution. However, there are the following disadvantages in the process of mixing and preparing the solution:

[0005] 1. As an insecticide, avermectin solution is highly volatile at high temperatures. Therefore, in order to ensure that the active ingredients of the drug are fully retained during the dispensing process, a mixer is required to mix the raw materials at low temperatures. Since dextran is a solid particle, the dissolution rate of dextran in purified water during low-temperature mixing is slow, resulting in low efficiency in the preparation of the drug solution.

[0006] 2. In order to improve the efficiency of liquid medicine preparation, the method of increasing the stirring speed of the mixer is often adopted. However, due to the fast stirring speed of the mixer, the liquid medicine easily combines with air to form foam, resulting in more bubbles in the liquid medicine after mixing, affecting the subsequent filling operation.

[0007] 3. After the raw materials are mixed, since dextran is a solid particle, it is necessary to test whether the dextran is fully dissolved. At this time, since the mixer is in a sealed state, it is difficult to sample and test the prepared liquid. Summary of the Invention

[0008] The purpose of the present invention is to provide a quantitative proportioning device for forestry pesticide application to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a quantitative proportioning device for forestry pesticide application, comprising a mixing tank, a sealing cover is provided on the upper end face of the mixing tank, the mixing tank and the sealing cover are fixedly connected by bolts, a blowing and suction pump is provided on the upper end face of the sealing cover, a high-speed stirring head is provided at the bottom of the internal cavity of the mixing tank, a drive shaft is provided below the high-speed stirring head, the high-speed stirring head is welded and fixed to the top end of the drive shaft, a brushless motor is provided below the mixing tank, the drive shaft extends downward out of the internal cavity of the mixing tank and is transmission-connected to the brushless motor.

[0010] As a preferred embodiment of the above technical solution, a shaft end seal is provided at the junction of the drive shaft and the mixing tank, which can achieve a technical sealing effect.

[0011] As a preferred embodiment of the above technical solution, four communicating holes are provided on the inner wall of the bottom of the mixing tank, and the four communicating holes are respectively installed with a purified water pipe, an abamectin solution pipe, a filling pipe and a detection pipe, and the purified water pipe, the abamectin solution pipe, the filling pipe and the detection pipe are respectively provided with a purified water valve, an abamectin solution valve, a filling valve and a detection valve, and the purified water pipe, the abamectin solution pipe, the filling pipe and the detection pipe are respectively connected to the purified water tank, the abamectin solution tank, the filling barrel and the detection warehouse at one end away from the mixing tank; the purified water tank is provided with a purified water one-way air inlet valve, and the abamectin solution tank is provided with an abamectin solution one-way air inlet valve.

[0012] As a preferred embodiment of the above technical solution, the right side of the detection tube extends into the internal cavity of the detection chamber, a transparent observation tube is provided in the detection chamber, a discharge pipe is provided on the right side of the detection chamber, the left and right ends of the transparent observation tube are respectively connected with the detection tube and the discharge pipe, a shooting module is provided on the inner wall of the bottom of the detection chamber, a waste liquid bin is provided on the right side of the discharge pipe, and the discharge pipe is connected to the waste liquid bin.

[0013] As a preferred embodiment of the above technical solution, a limiting groove is provided on the inner wall of the mixing tank, and an air baffle is also provided in the mixing tank. A clamping block is provided on the outer circumferential surface of the air baffle, and the clamping block is installed in the limiting groove for sliding up and down. A plurality of overflow holes are also provided on the upper end surface of the air baffle.

[0014] As a preferred embodiment of the above technical solution, the air baffle is made of PVC material and a porous ceramic sheet is fixedly provided on the upper end surface.

[0015] The present invention provides a quantitative proportioning device for forestry pesticide application, which has the following beneficial effects:

[0016] 1. During the mixing process, since the mixing tank is always in a negative pressure state and the raw material liquid level in the mixing tank is always in contact with the lower end surface of the air baffle, the contact area between the raw material and the air is greatly reduced during the mixing and stirring process, and the amount of bubbles generated during stirring is greatly reduced; at the same time, due to the negative pressure state in the mixing tank, the air dissolved in the raw material liquid can be accelerated to overflow, and the air and bubbles generated after the overflow can be discharged from the overflow hole. The discharged air will be sucked away by the suction pump, and the bubbles overflowing from the overflow hole will contact the upper end surface of the air baffle. The upper end surface of the air baffle is fixedly provided with a porous ceramic piece, which can quickly dissolve the foam. After the foam is dissolved, the raw material liquid can flow back to the bottom of the air baffle through the overflow hole; the porous ceramic piece is only fixed on the upper end surface of the air baffle because the service life of the porous ceramic piece is limited. If it is set on the lower end surface of the air baffle and immersed in the raw material liquid for a long time, its porous structure will be quickly blocked and its service life will be greatly shortened.

[0017] 2. When testing the solubility of the medicine, a suction pump is used to increase the pressure in the mixing tank and the test valve is only opened briefly. During the time when the test valve is open, the liquid medicine in the mixing tank will be pressed into the waste liquid bin under the action of pressure. During the process of the liquid medicine being pressed into the waste liquid bin, the camera module in the test bin will take pictures of the medicine passing through the transparent observation tube in the test bin and perform image recognition on the pictures to determine whether there are undissolved glucan hexaose particles in the medicine in the transparent observation tube. Based on this, it is determined whether the glucan hexaose is fully dissolved to distinguish whether the medicine is qualified.

[0018] 3. If the test fails, close the test valve and continue to stir and mix the liquid agent in the mixing tank, and repeat the previous test operation until the test is qualified. Due to the latter test, the liquid agent will flush the discharge pipe, transparent observation tube and test tube, so as to flush away the residual dextran hexaose particles on the tube wall, ensuring the accuracy of each solubility test.

[0019] 4. After filling is completed, open the purified water valve and use the suction pump to reduce the pressure in the mixing tank. At this time, the purified water in the purified water tank enters the mixing tank. Close the purified water valve and start the high-speed stirring head. The purified water can clean the inner wall of the mixing tank. After cleaning, open the detection valve and use the suction pump to increase the pressure in the mixing tank. At this time, the purified water rinses the discharge pipe, transparent observation tube and detection tube and discharges them into the mixing tank. Repeat the above steps to complete the thorough cleaning of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] See also Figure 1 and Figure 5 In this embodiment, a quantitative proportioning device for forestry pesticide application includes a mixing tank 1, a sealing cover 2 is provided on the upper end surface of the mixing tank 1, the mixing tank 1 and the sealing cover 2 are fixedly connected by bolts, a blowing and suction pump 3 is provided on the upper end surface of the sealing cover 2, a high-speed stirring head 4 is provided at the bottom of the internal cavity of the mixing tank 1, a driving shaft 5 is provided below the high-speed stirring head 4, the high-speed stirring head 4 is welded and fixed to the top of the driving shaft 5, a brushless motor 7 is provided below the mixing tank 1, the driving shaft 5 extends downward out of the internal cavity of the mixing tank 1 and is transmission-connected to the brushless motor 7.

[0029] Please continue reading Figure 5 Furthermore, a shaft end seal 6 is provided at the junction of the drive shaft 5 and the mixing tank 1, which can achieve a sealing technical effect.

[0030] In the specific implementation, the high-speed stirring head 4 is driven to rotate by the brushless motor 7, so that the raw materials in the mixing tank 1 are fully mixed and dispersed. The mixing tank 1 is sealed by the sealing cover 2, and the air pressure in the mixing tank 1 can be adjusted by the blowing and suction pump 3, which is convenient for realizing the pre-loading of pharmaceutical raw materials, the solubility detection of pharmaceuticals, the filling of qualified pharmaceuticals, the cleaning of the inner wall of the tank and other functions.

[0031] It should be noted that the mixing tank 1 has a built-in cooling module for ensuring that the raw materials are in a low-temperature environment during the mixing process. This is common technical knowledge in this field, so it will not be elaborated on. The working mode of the suction and blow pump 3 and the brushless motor 7 is programmed by the software of the upper computer and then the instructions are sent to the lower computer, and then the lower computer realizes the linkage control of the suction and blow pump 3 and the brushless motor 7. This is common technical knowledge in this field, so it will not be elaborated on.

[0032] As a further embodiment of the present invention, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 Four communicating holes 20 are provided on the inner wall of the bottom of the mixing tank 1, and the four communicating holes 20 are respectively installed with a purified water pipe 12, an abamectin solution pipe 14, a filling pipe 16 and a detection pipe 18. The purified water pipe 12, the abamectin solution pipe 14, the filling pipe 16 and the detection pipe 18 are respectively provided with a purified water valve 13, an abamectin solution valve 15, a filling valve 17 and a detection valve 19. The ends of the purified water pipe 12, the abamectin solution pipe 14, the filling pipe 16 and the detection pipe 18 away from the mixing tank 1 are respectively connected with a purified water tank 8, an abamectin solution tank 9, a canning barrel 10 and a detection chamber 11; a purified water one-way air inlet valve 81 is provided on the purified water tank 8, and an abamectin solution one-way air inlet valve 91 is provided on the abamectin solution tank 9.

[0033] In a specific implementation, the pre-loading of the pharmaceutical raw materials is achieved by the following operations: the dextran granules are pre-placed in the mixing tank 1, and the purified water and the abamectin solution are pre-placed in the purified water tank 8 and the abamectin solution tank 9, respectively. When the suction pump 3 pumps the mixing tank 1 into a negative pressure state, the purified water valve 13 and the abamectin solution valve 15 are opened, and the purified water and the abamectin solution in the purified water tank 8 and the abamectin solution tank 9 are sucked into the mixing tank 1 in a 1:1 ratio, thereby achieving the pre-loading of the pharmaceutical raw materials.

[0034] The filling of qualified medicines is achieved through the following operations: after the solubility test of the medicines is completed, the pressure in the mixing tank 1 is increased by the suction pump 3, and the filling valve 17 is opened. Under the action of pressure, the liquid medicine mixed in the mixing tank 1 will be pressed into the filling barrel 10 to complete the filling of the qualified medicines.

[0035] It should be noted that the working mode switching of the suction and blowing pump 3, the purified water valve 13, the avermectin solution valve 15, the filling valve 17 and the detection valve 19 is achieved by sending instructions to the slave computer after software programming of the upper computer, and then the slave computer realizes the linkage control of the suction and blowing pump 3, the purified water valve 13, the avermectin solution valve 15, the filling valve 17 and the detection valve 19 to realize the pre-loading of pharmaceutical raw materials, the solubility detection of the pharmaceutical, the filling of qualified pharmaceuticals, the cleaning of the inner wall of the tank and other functions. This is common knowledge in this field, so it will not be elaborated on.

[0036] It should be further noted that the concentration of the avermectin solution is 5%. The purified water tank 8 and the avermectin solution tank 9 are equipped with removable sealing caps for replenishing the raw materials in the purified water tank 8 and the avermectin solution tank 9. This is common knowledge in the art and will not be further described. The connection between the filling tube 16 and the canning barrel 10 is not sealed, so the liquid agent mixed in the mixing tank 1 can be pressed into the canning barrel 10. After filling is completed, the filling valve 17 is closed, the canning barrel 10 is sealed, and a new canning barrel 10 is replaced, and the previous filling steps are repeated.

[0037] As a further embodiment of the present invention, please refer to Figure 3 and Figure 6 The right side of the detection tube 18 extends into the internal cavity of the detection chamber 11. A transparent observation tube 21 is provided in the detection chamber 11. A discharge pipe 23 is provided on the right side of the detection chamber 11. The left and right ends of the transparent observation tube 21 are connected with the detection tube 18 and the discharge pipe 23 respectively. A shooting module 22 is provided on the inner wall of the bottom of the detection chamber 11. A waste liquid bin 24 is provided on the right side of the discharge pipe 23, and the discharge pipe 23 is connected to the waste liquid bin 24.

[0038] In a specific implementation, the solubility degree of the medicine is detected by the following operations: the mixing tank 1 is pressurized by the blowing and suction pump 3, and the detection valve 19 is briefly opened. During the time when the detection valve 19 is open, the liquid medicine in the mixing tank 1 will be pressed into the waste liquid bin 24 under the action of pressure. In the process of the liquid medicine being pressed into the waste liquid bin 24, the shooting module 22 in the detection bin 11 will take pictures of the medicine passing through the transparent observation tube 21 in the detection bin 11, and perform image recognition on the taken pictures to determine whether there are undissolved glucan hexaose particles in the medicine in the transparent observation tube 21, and thereby determine whether the glucan hexaose is fully dissolved to distinguish whether the medicine is qualified.

[0039] If the test fails, the test valve 19 is closed and the liquid medicine in the mixing tank 1 is continued to be stirred and mixed, and the previous test operation is repeated until the test is qualified. Due to the latter test, the liquid medicine will flush the discharge pipe 23, the transparent observation tube 21 and the test tube 18, so as to flush away the residual dextran hexaose particles on the tube wall, thereby ensuring the accuracy of each solubility test.

[0040] After the test is qualified, the qualified medicine is filled. After the filling is completed, the purified water valve 13 is opened, and the pressure in the mixing tank 1 is reduced by the suction pump 3. At this time, the purified water in the purified water tank 8 enters the mixing tank 1, and the purified water valve 13 is closed. The high-speed stirring head 4 is started, and the purified water can clean the inner wall of the mixing tank 1. After the cleaning is completed, the detection valve 19 is opened, and the pressure in the mixing tank 1 is increased by the suction pump 3. At this time, the purified water flushes the discharge pipe 23, the transparent observation tube 21 and the detection tube 18 and is discharged from the mixing tank 1. Repeat the above steps to complete the thorough cleaning of the equipment.

[0041] It should be noted that the control component of the shooting module 22 is an existing technology. The shooting module 22 captures images of the liquid medicine in the transparent observation tube 21 and transmits them to the host computer for analysis. This technology is also an existing technology, so it will not be described in detail.

[0042] As a further embodiment of the present invention, please refer to Figure 4 and Figure 5 A limiting groove 25 is provided on the inner wall of the mixing tank 1, and an air baffle 26 is also provided in the mixing tank 1. A clamping block 27 is provided on the outer circumferential surface of the air baffle 26. The clamping block 27 is slidably installed in the limiting groove 25 up and down, and a plurality of overflow holes 28 are also provided on the upper end surface of the air baffle 26.

[0043] Furthermore, the air baffle 26 is made of PVC and a porous ceramic sheet is fixedly provided on the upper end surface.

[0044] In a specific implementation, there are four limiting grooves 25, and the blocks 27 on the air baffles 26 correspond one to one with the limiting grooves 25. In this way, when the air baffles 26 are installed in the limiting grooves 25 by sliding up and down through the blocks 27, since the bottom of the limiting grooves 25 is higher than the high-speed stirring head 4, the height of the air baffles 26 can be limited to prevent the safety hazard of collision between the air baffles 26 and the high-speed stirring head 4. During the mixing process, the air baffles 26 and the blowing and suction pump 3 are used to eliminate the bubbles generated during the mixing process; during the mixing process, the blowing and suction pump 3 is used to keep the mixing tank 1 in a negative pressure state and the raw material liquid level in the mixing tank 1 is always in contact with the lower end face of the air baffle 26. Since the air baffles 26 are made of PVC, the density is much lower than the density of the raw material liquid. The air baffles 26 will rise with the rise of the liquid level, ensuring that the contact area between the raw material and the air during the mixing and stirring process is greatly reduced, and the amount of bubbles generated during stirring is greatly reduced; at the same time, due to the negative pressure state in the mixing tank 1, the air dissolved in the raw material liquid can also be accelerated to overflow, and the overflow will produce The air and bubbles can be discharged from the overflow hole 28, and the discharged air will be sucked away by the blowing and suction pump 3, and the bubbles overflowing from the overflow hole 28 will contact the upper end surface of the air baffle 26. The upper end surface of the air baffle 26 is fixed with a porous ceramic piece, which can quickly dissolve the foam. After the foam is dissolved, the raw material liquid can flow back to the bottom of the air baffle 26 through the overflow hole 28; the porous ceramic piece is only fixed on the upper end surface of the air baffle 26 because the service life of the porous ceramic piece is limited. If it is set on the lower end surface of the air baffle 26 and immersed in the raw material liquid for a long time, its porous structure will be quickly blocked and its service life will be greatly shortened.

[0045] It should be noted that the air baffle 26 is a consumable material. After a period of use, the porous structure of the porous ceramic sheet is blocked and the bubble dissolving ability is greatly reduced. At this time, the air baffle 26 needs to be replaced.

[0046] The working principle of the present invention is as follows:

[0047] The dextran granules are pre-placed in a mixing tank 1, and the purified water and the avermectin solution are pre-placed in a purified water tank 8 and an avermectin solution tank 9, respectively.

[0048] Take a new air baffle 26 and install it in the limit groove 25 of the mixing tank 1, use the sealing cover 2 to seal the mixing tank 1, at this time the suction and blowing pump 3 will pump the mixing tank 1 into a negative pressure state, and at the same time open the purified water valve 13 and the avermectin solution valve 15. At this time, the raw materials in the purified water tank 8 and the avermectin solution tank 9 will be sucked into the mixing tank 1 in a 1:1 ratio, realizing the pre-loading of the raw materials; during the raw material pre-loading process, when the liquid level of the raw materials contacts the lower end surface of the air baffle 26, since the density of the air baffle 26 is less than the density of the raw materials, the air baffle 26 will rise with the rise of the liquid level.

[0049] After the raw materials are pre-loaded, the purified water valve 13 and the avermectin solution valve 15 are closed, and the negative pressure state in the mixing tank 1 is continued to be maintained by the suction pump 3, and then the raw materials are fully mixed by stirring with the high-speed stirring head 4; during the mixing process, the air baffle 26 and the suction pump 3 are used to eliminate the bubbles generated during the mixing process; since the mixing tank 1 is always in a negative pressure state and the raw material liquid level in the mixing tank 1 is always in contact with the lower end surface of the air baffle 26, it is ensured that the contact area between the raw materials and the air during the mixing and stirring process is greatly reduced, and the amount of bubbles generated during stirring is greatly reduced; at the same time, the negative pressure state in the mixing tank 1 can also make the air dissolved in the raw material liquid Accelerate overflow. The air and bubbles generated after overflow can be discharged from the overflow hole 28. The discharged air will be sucked away by the suction pump 3, and the bubbles overflowing from the overflow hole 28 will contact the upper end surface of the air baffle 26. The upper end surface of the air baffle 26 is fixed with a porous ceramic piece. The porous ceramic piece can quickly dissolve the foam. After the foam is dissolved, the raw material liquid can flow back to the bottom of the air baffle 26 through the overflow hole 28; the porous ceramic piece is only fixed on the upper end surface of the air baffle 26 because the service life of the porous ceramic piece is limited. If it is set on the lower end surface of the air baffle 26 and immersed in the raw material liquid for a long time, its porous structure will be quickly blocked and its service life will be greatly shortened.

[0050] After the mixing is completed, the solubility degree of the medicine is detected by the following operations: the pressure in the mixing tank 1 is increased by the suction pump 3, and the detection valve 19 is briefly opened. During the time when the detection valve 19 is open, the liquid medicine in the mixing tank 1 will be pressed into the waste liquid bin 24 under the action of pressure. In the process of the liquid medicine being pressed into the waste liquid bin 24, the shooting module 22 in the detection bin 11 will take pictures of the medicine passing through the transparent observation tube 21 in the detection bin 11, and perform image recognition on the taken pictures to determine whether there are undissolved dextran hexaose particles in the medicine in the transparent observation tube 21, and thereby determine whether the dextran hexaose is fully dissolved to distinguish whether the medicine is qualified.

[0051] If the test fails, the test valve 19 is closed and the liquid medicine in the mixing tank 1 is continued to be stirred and mixed, and the previous test operation is repeated until the test is qualified. Due to the latter test, the liquid medicine will flush the discharge pipe 23, the transparent observation tube 21 and the test tube 18, so as to flush away the residual dextran hexaose particles on the tube wall, thereby ensuring the accuracy of each solubility test.

[0052] The filling of qualified medicines is achieved through the following operations: after the solubility test of the medicines is completed, the pressure in the mixing tank 1 is increased by the suction pump 3, and the filling valve 17 is opened. Under the action of pressure, the liquid medicine mixed in the mixing tank 1 will be pressed into the filling barrel 10 to complete the filling of the qualified medicines.

[0053] After the filling is completed, open the purified water valve 13 and use the suction pump 3 to reduce the pressure in the mixing tank 1. At this time, the purified water in the purified water tank 8 enters the mixing tank 1. Close the purified water valve 13 and start the high-speed stirring head 4. The purified water can clean the inner wall of the mixing tank 1. After the cleaning is completed, open the detection valve 19 and use the suction pump 3 to increase the pressure in the mixing tank 1. At this time, the purified water flushes the discharge pipe 23, the transparent observation tube 21 and the detection tube 18 and is discharged from the mixing tank 1. Repeat the above steps to complete the thorough cleaning of the equipment.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
