Description

Technical Field

[0001] The present invention relates to the technical field of quantitative proportioning devices, and specifically relates to a quantitative proportioning device for forestry medicine application. Background Art

[0002] Pine wilt disease is a devastating forest disease caused by Bursaphelenchus xylophilus, known as the "cancer of pine trees", which is characterized by fast transmission, high lethality, and difficult prevention and control. Glucohexaose is an oligosaccharide product. Its oligosaccharide chain is often the recognition site of receptors and enzymes. By covalently connecting with proteins, one or several glycoproteins are formed. The sugar chains in glycoproteins vary greatly, contain rich structural information, and can effectively change the protein structure and the activity of some proteins.

[0003] When using glucohexaose to control Bursaphelenchus xylophilus, its disease resistance mechanism is, on the one hand, to inhibit some pathogenic proteins, extracellular polysaccharides, peptides and other pathogenic factors on the surface of Bursaphelenchus xylophilus through covalent bond binding, and on the other hand, to activate the immune system of pine trees to regulate plant organisms, enhance photosynthesis ability, and improve disease resistance and stress resistance. Thus, it can activate and improve the self-immunity ability of pine trees, enabling the formation of a symbiotic biological chain where there are nematodes but the trees do not die.

[0004] In the prior art, glucohexaose, the corresponding insecticide, and a strong penetration and strong conduction aid can be mixed and formulated into a pine wilt disease control liquid medicine. However, there are the following disadvantages in the process of mixing and formulating the liquid medicine: 1. As an insecticide, abamectin solution has the characteristic of strong volatility at high temperatures. Therefore, in order to ensure the full retention of the effective components of the medicine during the medicine mixing process, a mixer needs to be used to mix the raw materials under low-temperature conditions. Also, because glucohexaose is a solid particle, the dissolution rate of glucohexaose in purified water is slow during the low-temperature mixing process, resulting in low efficiency of liquid medicine preparation.

[0005] 2. In order to improve the efficiency of liquid medicine preparation, the method of increasing the stirring speed of the mixer is often used. However, due to the relatively fast stirring speed of the mixer, the liquid medicine is prone to combine with air to form foam, resulting in a large number of bubbles in the liquid medicine after mixing, which affects the subsequent filling operation.

[0006] 3. After the raw materials are mixed, since glucohexaose is a solid particle, it is necessary to detect whether glucohexaose is fully dissolved. At this time, since the mixer is in a sealed state, it is relatively difficult to take samples of the prepared liquid medicine for detection. Summary of the Invention

[0007] The purpose of the present invention is to provide a quantitative proportioning device for forestry medicine application to solve the problems raised in the above background art.

[0008] To achieve the above object, the present invention provides the following technical solutions. A quantitative proportioning device for forestry medication application includes a mixing tank. A sealing cover is provided on the upper end surface 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 surface of the sealing cover. A high-speed stirring head is provided at the bottom of the internal cavity of the mixing tank. A driving shaft is provided below the high-speed stirring head. The high-speed stirring head is welded and fixed to the top of the driving shaft. A brushless motor is provided below the mixing tank. The driving shaft extends downward out of the internal cavity of the mixing tank and is in transmission connection with the brushless motor.

[0009] As a preference of the above technical solution, a shaft end seal is provided at the junction of the driving shaft and the mixing tank, which can achieve the technical effect of sealing.

[0010] As a preference of the above technical solution, four communication holes are opened on the bottom inner wall of the mixing tank. A purified water pipe, an avermectin solution pipe, a filling pipe, and a detection pipe are respectively installed and communicated on the four communication holes. A purified water valve, an avermectin solution valve, a filling valve, and a detection valve are respectively provided on the purified water pipe, the avermectin solution pipe, the filling pipe, and the detection pipe. The ends of the purified water pipe, the avermectin solution pipe, the filling pipe, and the detection pipe away from the mixing tank are respectively communicated with a purified water tank, an avermectin solution tank, a filling barrel, and a detection chamber. A purified water one-way intake valve is provided on the purified water tank. An avermectin solution one-way intake valve is provided on the avermectin solution tank.

[0011] As a preference of the above technical solution, the right side of the detection pipe extends into the internal cavity of the detection chamber. A transparent observation pipe 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 pipe are respectively communicated with the detection pipe and the discharge pipe. A shooting module is provided on the bottom inner wall of the detection chamber. A waste liquid chamber is provided on the right side of the discharge pipe. The discharge pipe is communicated with the waste liquid chamber.

[0012] As a preference of the above technical solution, a limiting groove is opened on the inner wall of the mixing tank. An air partition is also provided in the mixing tank. A clamping block is provided on the outer circumferential surface of the air partition. The clamping block is slidably installed up and down in the limiting groove. A plurality of overflow holes are also opened on the upper end surface of the air partition.

[0013] As a preference of the above technical solution, the air partition is made of PVC material and a porous ceramic sheet is fixedly provided on the upper end surface.

[0014] The present invention provides a quantitative proportioning device for forestry medication application, having the following beneficial effects: 1. During the mixing process, since the inside of the mixing tank is always in a negative pressure state and the liquid level of the raw materials in the mixing tank always contacts the lower end surface of the air baffle, 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 generation amount of bubbles 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 medicine can also be accelerated to overflow. The air and bubbles generated after overflow can be discharged from the overflow holes, and the discharged air will be pumped away by the blowing and suction pump. The bubbles overflowing from the overflow holes 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 sheet, and the porous ceramic sheet can quickly dissolve the foam. After the foam is dissolved, the raw material liquid medicine can flow back to the lower part of the air baffle through the overflow holes. Only the porous ceramic sheet is fixedly provided on the upper end surface of the air baffle because the service life of the porous ceramic sheet is limited. If it is set on the lower end surface of the air baffle and soaked in the raw material liquid medicine for a long time, its porous structure will be quickly blocked, and the service life will be greatly shortened.

[0015] 2. When detecting the dissolution degree of the medicine, the blowing and suction pump is used to increase the pressure in the mixing tank, and only the detection valve is briefly opened. During the time when the detection valve is opened, under the action of pressure, the liquid medicine in the mixing tank will be pressed into the waste liquid bin. During the process of the liquid medicine being pressed into the waste liquid bin, the shooting module in the detection bin will shoot the liquid medicine passing through the transparent observation tube in the detection bin, and perform image recognition on the taken pictures to judge whether there are undissolved glucan hexose particles in the medicine in the transparent observation tube, and judge whether the glucan hexose is fully dissolved based on this, so as to distinguish whether the medicine is qualified.

[0016] 3. If the detection is unqualified, after closing the detection valve, continue to stir and mix the liquid medicine in the mixing tank, and then repeat the previous detection operation until the detection is qualified. Due to the subsequent detection, the liquid medicine will wash the discharge pipe, the transparent observation tube and the detection tube, which is convenient for washing away the residual glucan hexose particles on the pipe wall, and ensures the accuracy of each dissolution degree detection.

[0017] 4. After the filling is completed, open the purified water valve, and use the blowing and 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 the cleaning is completed, open the detection valve, and use the blowing and suction pump to increase the pressure in the mixing tank. At this time, the purified water flushes the discharge pipe, the transparent observation tube and the detection tube and discharges them from the mixing tank. Repeating the above steps can complete the thorough cleaning of the equipment. Brief Description of the Drawings

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Please refer to Figure 1 and Figure 5 , in this embodiment, a quantitative ratio device for forestry application includes a mixing tank 1. A sealing cover 2 is arranged on the upper end face 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 arranged on the upper end face of the sealing cover 2. A high-speed stirring head 4 is arranged at the bottom of the inner cavity of the mixing tank 1. A drive shaft 5 is arranged below the high-speed stirring head 4. The high-speed stirring head 4 is fixedly welded to the top of the drive shaft 5. A brushless motor 7 is arranged below the mixing tank 1. The drive shaft 5 extends downward out of the inner cavity of the mixing tank 1 and is in transmission connection with the brushless motor 7.

[0022] Please continue to refer to Figure 5 , further, a shaft end seal 6 is arranged at the junction of the drive shaft 5 and the mixing tank 1, which can achieve the technical effect of sealing.

[0023] In specific implementation, the high-speed stirring head 4 is driven by the brushless motor 7 to rotate, 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. The air pressure in the mixing tank 1 can be adjusted through the blowing and suction pump 3, which is convenient for realizing multiple functions such as preloading of pharmaceutical raw materials, detection of the dissolution degree of pharmaceuticals, filling of qualified pharmaceuticals, and cleaning of the inner wall of the tank.

[0024] It should be noted that the mixing tank 1 is equipped with a cooling module to ensure that the raw materials are in a low-temperature environment during the mixing process. This is common general knowledge in the art and will not be elaborated further. The working modes of the suction-blowing pump 3 and the brushless motor 7 are programmed by the software of the host computer to send instructions to the lower computer, and then the lower computer realizes the linkage control of the suction-blowing pump 3 and the brushless motor 7. This is common general knowledge in the art and will not be elaborated further.

[0025] As a further implementation scheme of the present invention, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , four communication holes 20 are opened on the bottom inner wall of the mixing tank 1, and a purified water pipe 12, an avermectin solution pipe 14, a filling pipe 16 and a detection pipe 18 are respectively installed and communicated on the four communication holes 20. A purified water valve 13, an avermectin solution valve 15, a filling valve 17 and a detection valve 19 are respectively arranged on the purified water pipe 12, the avermectin solution pipe 14, the filling pipe 16 and the detection pipe 18. One ends of the purified water pipe 12, the avermectin solution pipe 14, the filling pipe 16 and the detection pipe 18 away from the mixing tank 1 are respectively communicated with a purified water tank 8, an avermectin solution tank 9, a filling barrel 10 and a detection chamber 11; a purified water one-way intake valve 81 is arranged on the purified water tank 8, and an avermectin solution one-way intake valve 91 is arranged on the avermectin solution tank 9.

[0026] In specific implementation, the preloading of the pharmaceutical raw materials is realized through the following operations: pre-place the glucooligosaccharide particles in the mixing tank 1, and pre-place the purified water and the avermectin solution in the purified water tank 8 and the avermectin solution tank 9 respectively. When the suction-blowing pump 3 pumps the inside of the mixing tank 1 into a negative pressure state, at this time, open the purified water valve 13 and the avermectin solution valve 15, and the purified water and the avermectin solution in the purified water tank 8 and the avermectin solution tank 9 will be sucked into the mixing tank 1 in a ratio of 1:1 to realize the preloading of the pharmaceutical raw materials.

[0027] The filling of the qualified pharmaceutical is realized through the following operations: for the pharmaceutical that has passed the detection of the dissolution degree of the pharmaceutical, use the suction-blowing pump 3 to pressurize the inside of the mixing tank 1, and open the filling valve 17. Under the action of pressure, the mixed liquid pharmaceutical in the mixing tank 1 will be pressed into the filling barrel 10 to complete the filling of the qualified pharmaceutical.

[0028] It should be noted that the switching of the working modes of the suction-blowing pump 3, the purified water valve 13, the avermectin solution valve 15, the filling valve 17 and the detection valve 19 is to program the software of the host computer to send instructions to the lower computer, and then the lower computer realizes the linkage control of the suction-blowing pump 3, the purified water valve 13, the avermectin solution valve 15, the filling valve 17 and the detection valve 19 to realize multiple functions such as the preloading of the pharmaceutical raw materials, the detection of the dissolution degree of the pharmaceutical, the filling of the qualified pharmaceutical, and the cleaning of the inner wall of the tank. This is common general knowledge in the art and will not be elaborated further.

[0029] Further, it should be noted that the concentration of the avermectin solution is 5%. The purification water tank 8 and the avermectin solution tank 9 are equipped with detachable sealing covers for supplementing the raw materials in the purification water tank 8 and the avermectin solution tank 9, which is common knowledge in the art, so it will not be elaborated here. The connection between the filling pipe 16 and the filling barrel 10 is not in a sealed state. Therefore, the liquid medicine mixed in the mixing tank 1 can be pressed into the filling barrel 10. After filling, the filling valve 17 is closed, and the staff seals the filling barrel 10 and then replaces it with a new filling barrel 10, and repeats the previous filling steps.

[0030] As a further embodiment of the present invention, please refer to Figure 3 and Figure 6 , the right side of the detection pipe 18 extends into the internal cavity of the detection chamber 11. A transparent observation pipe 21 is arranged in the detection chamber 11. An outlet pipe 23 is arranged on the right side of the detection chamber 11. The left and right ends of the transparent observation pipe 21 are respectively communicated with the detection pipe 18 and the outlet pipe 23. A shooting module 22 is arranged on the bottom inner wall of the detection chamber 11. A waste liquid chamber 24 is arranged on the right side of the outlet pipe 23, and the outlet pipe 23 is communicated with the waste liquid chamber 24.

[0031] In specific implementation, the detection of the dissolution degree of the medicine is realized through the following operations: the pressure in the mixing tank 1 is increased by using the blowing and suction pump 3, and the detection valve 19 is briefly opened. During the time when the detection valve 19 is opened, under the action of pressure, the liquid medicine in the mixing tank 1 will be pressed into the waste liquid chamber 24. During the process of pressing the liquid medicine into the waste liquid chamber 24, the shooting module 22 in the detection chamber 11 takes pictures of the liquid medicine passing through the transparent observation pipe 21 in the detection chamber 11, and performs image recognition on the taken pictures to judge whether there are undissolved glucosamine hexasaccharide particles in the medicine in the transparent observation pipe 21, and accordingly judge whether the glucosamine hexasaccharide is fully dissolved to distinguish whether the medicine is qualified.

[0032] If the detection is unqualified, after closing the detection valve 19, continue to stir and mix the liquid medicine in the mixing tank 1, and then repeat the previous detection operation until the detection is qualified. Due to the subsequent detection, the liquid medicine will wash the outlet pipe 23, the transparent observation pipe 21 and the detection pipe 18, which is convenient for washing away the residual glucosamine hexasaccharide particles on the pipe wall and ensures the accuracy of each dissolution degree detection.

[0033] After passing the inspection, the qualified medicament is filled. After the filling is completed, the purified water valve 13 is opened, and the suction pump 3 is used 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. The purified water valve 13 is closed, and the high-speed stirring head 4 is started. The purified water can clean the inner wall of the mixing tank 1. After the cleaning is completed, the inspection valve 19 is opened, and the suction pump 3 is used to increase the pressure in the mixing tank 1. At this time, the purified water flushes the discharge pipe 23, the transparent observation pipe 21 and the inspection pipe 18 and discharges them from the mixing tank 1. Repeating the above steps can complete the thorough cleaning of the equipment.

[0034] It should be noted that the control component of the shooting module 22 is a prior art. The shooting module 22 takes pictures of the liquid medicament in the transparent observation pipe 21 and transmits them to the host computer for analysis. This technology is also a prior art, so it will not be elaborated here.

[0035] As a further implementation 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 partition 26 is further provided in the mixing tank 1. A clamping block 27 is provided on the outer circumferential surface of the air partition 26, and the clamping block 27 is slidably installed up and down in the limiting groove 25. A plurality of overflow holes 28 are further provided on the upper end surface of the air partition 26.

[0036] Furthermore, the air partition 26 is made of PVC material and a porous ceramic sheet is fixedly arranged on the upper end surface.

[0037] In specific implementation, the number of the limiting grooves 25 is four, and the clamping blocks 27 on the air partition plate 26 correspond to the limiting grooves 25 one by one. When the air partition plate 26 is slidably installed in the limiting grooves 25 through the clamping blocks 27, since the bottom of the limiting grooves 25 is higher than the high-speed stirring head 4, the height of the air partition plate 26 can be limited to prevent the potential safety hazard of the air partition plate 26 colliding with the high-speed stirring head 4. During the mixing process, the air partition plate 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 keeps the inside of the mixing tank 1 in a negative pressure state and the liquid level of the raw materials in the mixing tank 1 always contacts the lower end surface of the air partition plate 26. Since the air partition plate 26 is made of PVC material and its density is much smaller than that of the raw material liquid medicine, the air partition plate 26 will rise with the rise of the liquid level, ensuring that the contact area between the raw materials and the air during the mixing and stirring process is greatly reduced, and the generation amount of bubbles 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 medicine can also be accelerated to overflow. The generated air and bubbles after overflow can be discharged from the overflow holes 28, and the discharged air will be pumped away by the blowing and suction pump 3. The bubbles overflowing from the overflow holes 28 will contact the upper end surface of the air partition plate 26. The upper end surface of the air partition plate 26 is fixedly provided with a porous ceramic sheet, and the porous ceramic sheet can quickly eliminate the foam. After the foam is eliminated, the raw material liquid medicine can flow back to the lower part of the air partition plate 26 through the overflow holes 28; only the upper end surface of the air partition plate 26 is fixedly provided with a porous ceramic sheet because the service life of the porous ceramic sheet is limited. If it is set on the lower end surface of the air partition plate 26 and soaked in the raw material liquid medicine for a long time, its porous structure will be quickly blocked and its service life will be greatly shortened.

[0038] It should be noted that the air partition plate 26 is a consumable. After being used for a period of time, the porous structure of the porous ceramic sheet is blocked and the bubble elimination ability is greatly reduced. At this time, the air partition plate 26 needs to be replaced.

[0039] The working principle of the present invention is as follows: The glucan hexasaccharide particles are pre-placed in the mixing tank 1, and the purified water and the abamectin solution are respectively pre-placed in the purified water tank 8 and the abamectin solution tank 9.

[0040] Take a new air partition plate 26 and install it in the limiting grooves 25 of the mixing tank 1. Use the sealing cover 2 to seal the mixing tank 1. At this time, the blowing and suction pump 3 pumps the inside of the mixing tank 1 into a negative pressure state. At the same time, open the purified water valve 13 and the abamectin solution valve 15. At this time, the raw materials in the purified water tank 8 and the abamectin solution tank 9 will be sucked into the mixing tank 1 in a ratio of 1:1 to realize the pre-installation of the raw materials; during the pre-installation of the raw materials, when the liquid level of the raw materials contacts the lower end surface of the air partition plate 26, since the density of the air partition plate 26 is less than that of the raw materials, the air partition plate 26 will rise with the rise of the liquid level.

[0041] After the raw materials are pre-loaded, close the purified water valve 13 and the avermectin solution valve 15. At the same time, continue to maintain the negative pressure state in the mixing tank 1 through the suction and blowing pump 3, and then fully mix the raw materials through the stirring of the high-speed stirring head 4. During the mixing process, use the air partition 26 and the suction and blowing pump 3 to eliminate the bubbles generated during the mixing process. Since the inside of the mixing tank 1 is always in a negative pressure state and the liquid level of the raw materials in the mixing tank 1 always contacts the lower end surface of the air partition 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 generation amount of bubbles 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 medicine can also be accelerated to overflow. The air and bubbles generated after overflow can be discharged from the overflow hole 28, and the discharged air will be sucked away by the suction and blowing pump 3. The bubbles overflowing from the overflow hole 28 will contact the upper end surface of the air partition 26. The upper end surface of the air partition 26 is fixedly provided with a porous ceramic sheet, and the porous ceramic sheet can quickly eliminate the foam. After the foam is eliminated, the raw material liquid medicine can flow back to the lower part of the air partition 26 through the overflow hole 28. Only the upper end surface of the air partition 26 is fixedly provided with a porous ceramic sheet because the service life of the porous ceramic sheet is limited. If it is set on the lower end surface of the air partition 26 and soaked in the raw material liquid medicine for a long time, its porous structure will be quickly blocked, and the service life will be greatly shortened.

[0042] After mixing is completed, the detection of the dissolution degree of the medicament is realized through the following operations: Use the suction and blowing pump 3 to increase the pressure in the mixing tank 1, and briefly open the detection valve 19. During the time when the detection valve 19 is open, under the action of pressure, the liquid medicament in the mixing tank 1 will be pressed into the waste liquid bin 24. During the process of the liquid medicament being pressed into the waste liquid bin 24, the shooting module 22 in the detection bin 11 will shoot the liquid medicament passing through the transparent observation tube 21 in the detection bin 11, and perform image recognition on the taken pictures to judge whether there are undissolved glucosamine hexasaccharide particles in the medicament in the transparent observation tube 21, and judge whether the glucosamine hexasaccharide is fully dissolved accordingly to distinguish whether the medicament is qualified.

[0043] If the detection is unqualified, after closing the detection valve 19, continue to stir and mix the liquid medicament in the mixing tank 1, and then repeat the previous detection operation until the detection is qualified. Due to the subsequent detection, the liquid medicament will wash the discharge pipe 23, the transparent observation tube 21 and the detection tube 18, which is convenient for washing away the residual glucosamine hexasaccharide particles on the pipe wall and ensures the accuracy of each dissolution degree detection.

[0044] The filling of the qualified medicament is realized through the following operations: For the medicament that has passed the detection of the dissolution degree of the medicament, use the suction and blowing pump 3 to increase the pressure in the mixing tank 1, and open the filling valve 17. Under the action of pressure, the liquid medicament mixed in the mixing tank 1 will be pressed into the filling barrel 10 to complete the filling of the qualified medicament.

[0045] After filling is completed, open the purified water valve 13, and use the air-blowing and 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 air-blowing and 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 pipe 21, and the detection pipe 18 and discharges them from the mixing tank 1. Repeating the above steps can complete the thorough cleaning of the equipment.

[0046] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
