Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drip irrigation tape, in particular to a kind of anti-insect bite drip irrigation tape coating equipment and anti-insect bite drip irrigation tape production method. BACKGROUND

[0002] In modern agricultural irrigation system, drip irrigation technology with its most water-saving potential characteristics becomes one of the hotspots of irrigation technology research at home and abroad in recent years, and the stability and durability of drip irrigation tape are directly related to water resource utilization efficiency and crop yield. However, the damage of the multi-class harmful organisms (containing 10 orders and 23 species of Coleoptera, Hemiptera, Lepidoptera, etc. in field trapping and field monitoring) commonly existing in field environment to drip irrigation tape has become an important problem restricting system operation. Because of foraging or tooth grinding instinct, these animals often bite drip irrigation tape buried in the surface layer or laid on the ground, resulting in pipe wall damage or even overall rupture.

[0003] At present, the traditional countermeasures mainly have the following two kinds, the first kind relies on artificial patrol repair or sprays insect repellent, but there are three defects: one is hysteresis, passive treatment after damage occurs, which greatly affects irrigation and fertilization uniformity, causing serious waste of water resources; two is poor economy, frequent maintenance will increase labor and material cost; three is ecological risk, large area of chemical agent spraying may destroy soil microbial balance. The second kind is to mix insect repellent (matrine, azadirachtin, synthetic capsaicin, etc.) into the masterbatch to produce drip irrigation tape. However, the insect repellent ingredients in the drip irrigation tape may react with other masterbatch ingredients (such as polyethylene, anti-aging agent, etc.), resulting in significant decrease of drip irrigation tape mechanical strength, easy brittleness or accelerated aging. SUMMARY

[0004] (I) The problem to be solved by the present application is to solve the technical problems raised in the background.

[0005] (II) Technical scheme

[0006] An anti-insect bite drip irrigation tape coating equipment is arranged between a punching equipment and a winding equipment, and comprises a sealed shell, a plurality of liquid storage tanks, a liquid supply mechanism, a mixer, a peristaltic pump, a liquid delivery pipe, at least one coating member and a hot air curing mechanism.

[0007] The sealed shell is provided with an inlet and an outlet at two ends respectively for the drip irrigation tape to pass through, the coating member is arranged inside the sealed shell for coating the drip irrigation tape passing through the coating member with insecticide, and the hot air curing mechanism is installed at the outlet of the sealed shell and communicates with the outlet, and is used for drying and curing the insecticide on the drip irrigation tape.

[0008] The drip irrigation tape passes through the inlet, the coating member, the outlet and the hot air curing mechanism in sequence.

[0009] The liquid supply mechanism corresponds to the liquid storage tank one by one, and is used to transport the liquid medicine in the corresponding liquid storage tank to the mixer, and the mixer is used to stir and mix the liquid medicine inside it;

[0010] One end of the infusion tube extends into the mixer, and the other end thereof is connected to the coating member after passing through the peristaltic pump. The peristaltic pump is used to transport the liquid medicine in the mixer to the coating member through the infusion tube.

[0013] A gap for the drip irrigation tape to pass through is formed between the two sponge blocks, and the distance between the two sponge blocks is less than the thickness of the drip irrigation tape.

[0014] According to one embodiment of the present invention, the liquid supply mechanism includes a metering pump, a first pipeline and a second pipeline. The liquid inlet of the metering pump is connected to the liquid storage tank through the first pipeline, and the liquid outlet of the metering pump is connected to the mixer through the second pipeline.

[0015] According to one embodiment of the present invention, the hot air curing mechanism includes a hot air blower, a curing cylinder and a hot air pipe, the curing cylinder having an inlet and an outlet relative to each other, the inlet of the curing cylinder being connected to the discharge port of the sealing shell, and the outlet of the curing cylinder being connected to the external environment;

[0016] One end of the hot air pipe is connected to the hot air blower, and the other end is connected to the curing cylinder.

[0017] According to one embodiment of the present invention, it includes an exhaust mechanism, which includes an exhaust pipe, an exhaust fan and an activated carbon adsorption tower. One end of the exhaust pipe is connected to the sealed shell, and the other end is connected to the activated carbon adsorption tower. The exhaust fan is installed on the inner wall of the exhaust pipe near one end of the sealed shell.

[0018] According to one embodiment of the present invention, two coating members are provided, and the two coating members are arranged along the moving direction of the drip irrigation belt. The peristaltic pump is a multi-channel peristaltic pump, and two infusion tubes are provided.

[0019] According to one embodiment of the present invention, the mixer is provided with an agitator.

[0020] According to one embodiment of the present invention, a propeller stirrer is installed in the liquid storage tank.

[0021] According to one embodiment of the present invention, a method for producing an insect bite-proof drip irrigation tape, using the above-mentioned insect bite-proof drip irrigation tape coating device, includes the following steps:

[0022] S1: Pass the drip irrigation tape through the feed port of the sealing shell, the coating component, the discharge port of the sealing shell and the hot air curing mechanism in sequence, and then connect the end of the drip irrigation tape to the winding device;

[0023] S2: placing three functional liquids of phoxim insect repellent, aldicarb, and synthetic capsaicin into three liquid storage tanks respectively, and then starting the liquid supply mechanism to feed the phoxim insect repellent, synthetic capsaicin rodent repellent, and aldicarb synergist into the mixer in a certain mass fraction ratio for mixing;

[0027] Beneficial effects of the present invention:

[0028] Using this anti-insect bite drip irrigation tape coating equipment to apply anti-insect liquid to the drip irrigation tape has at least the following advantages:

[0029] First, as the drip tape passes through the gap between the two sponge blocks, the sponge blocks gently press down on the tape, evenly coating the synthetic liquid across its surface. Compared to manual spraying of insect repellent, this method ensures a uniform coating of the repellent across the tape, avoiding the potential for uneven distribution of the repellent with manual spraying, resulting in excessive amounts of repellent in some areas, which can cause waste or negatively impact crops, and insufficient amounts in others, leading to ineffective insect control.

[0030] Second, the entire coating process is automated. From the drip irrigation tape feeding, the insecticide mixture and coating to the curing and winding, a series of operations can be carried out continuously. Compared with the traditional way of manual inspection and repair and spraying insecticide, the work efficiency is greatly improved. Manual operation requires a lot of time and manpower to check the damage of drip irrigation tape and repair or spray insecticide, while this device can complete the insecticide coating operation simultaneously during the production or laying of drip irrigation tape.

[0031] Third, although the device itself may have some initial investment, it can save costs in the long run. Compared with frequent manual maintenance and material replacement, this device can effectively reduce the frequency of drip irrigation tape damage caused by pests, prolong the service life of drip irrigation tape, and thus reduce the frequency of drip irrigation system update and maintenance, and reduce the cost of labor and materials.

[0032] Fourth, through precise proportioning and uniform coating, overuse of insecticide can be avoided. Compared with the traditional way of spraying insecticide, this way will not spray a large amount of insecticide into the soil and surrounding environment, reducing the risk of destroying the balance of soil microorganisms and reducing the pollution of chemical agents to the surrounding ecological environment.

[0033] Fifth, the entire mixing, delivery and coating process of the insecticide is carried out in a relatively closed environment inside the device, reducing the opportunity for operators to come into direct contact with the insecticide and reducing the risk of poisoning operators due to contact with toxic chemicals, making it safer than the traditional way of manually spraying insecticide.

[0034] Sixth, the device coats the insecticide on the surface of the drip irrigation tape, which is different from the way of mixing the insecticide into the masterbatch to produce drip irrigation tape, and there is no chemical reaction between the insecticide and the masterbatch components such as polyethylene and anti-aging agents. This can avoid problems such as reduced mechanical strength, brittle or accelerated aging of drip irrigation tape, and ensure the stability and durability of drip irrigation tape.

[0040] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] Example 1:

[0042] like Figures 1-3 As shown, the first embodiment of the present invention provides an insect bite-proof drip irrigation tape coating device, which is arranged between a punching device and a winding device. The insect bite-proof drip irrigation tape coating device includes a sealed shell 3, multiple liquid storage tanks 1, a liquid supply mechanism, a mixer 12, a peristaltic pump, a liquid infusion tube, at least one coating member, and a hot air curing mechanism.

[0043] The sealing shell 3 is provided with a feed port 303 and a discharge port for the drip irrigation tape to pass through at both ends. The coating member is arranged inside the sealing shell 3 and is used to apply liquid medicine to the drip irrigation tape passing through the coating member. The hot air curing mechanism is installed at the discharge port of the sealing shell 3 and is connected to the discharge port. The hot air curing mechanism is used to dry and cure the liquid medicine on the drip irrigation tape.

[0044] The drip irrigation tape passes through the feed port 303, the coating component, the discharge port and the hot air curing mechanism in sequence;

[0045] The liquid supply mechanism corresponds to the liquid storage tank 1 one by one. The liquid supply mechanism is used to transport the liquid medicine in the corresponding liquid storage tank 1 to the mixer 12. The mixer 12 is used to stir and mix the liquid medicine therein.

[0046] One end of the infusion tube extends into the mixer 12, and the other end thereof is connected to the coating member after passing through the peristaltic pump. The peristaltic pump is used to transport the liquid medicine in the mixer 12 to the coating member through the infusion tube.

[0047] In this embodiment, phoxim, synthetic capsaicin and aldicarb are respectively placed in three liquid storage tanks 1, and then the liquid supply mechanism is used to send phoxim, synthetic capsaicin and aldicarb into the mixer 12 according to a certain mass fraction ratio for mixing. Subsequently, the peristaltic pump is turned on to pump the synthetic liquid in the mixer 12 to the coating part, and then the hot air curing mechanism and the winding device are turned on. As the winding device is turned on, the drip irrigation tape passes through the coating part during its movement, so that the synthetic liquid is applied to the surface of the drip irrigation tape by the coating part. At the same time, the hot air curing mechanism blows out hot air to surround the drip irrigation tape to achieve rapid curing of the coating.

[0048] In this embodiment, if Figure 1 and Figure 2 As shown, there are three liquid storage tanks 1, each of which stores phoxim, synthetic capsaicin and aldicarb. Three corresponding liquid supply mechanisms are also provided.

[0049] In this embodiment, the liquid supply mechanism includes a metering pump 2, a first pipe, and a second pipe. One end of the first pipe is connected to the liquid inlet of metering pump 2, and the other end extends into the interior of liquid storage tank 1. One end of the second pipe is connected to the liquid outlet of metering pump 2, and the other end is connected to mixer 12. The three metering pumps 2 enable precise control of the mass fraction ratio of phoxim, synthetic capsaicin, and aldicarb.

[0050] In some embodiments, a first agitator 102 is installed on each liquid storage tank 1. The first agitator 102 is a propeller agitator. The liquid medicine inside the liquid storage tank 1 is stirred by the propeller agitator so that the viscosity fluctuation of the liquid medicine is ≤5%.

[0051] In some embodiments, a second stirrer 13 is installed in the mixer 12 to ensure that phoxim, synthetic capsaicin and aldicarb are fully mixed in the mixer 12 .

[0052] In some embodiments, as Figure 1 As shown, each liquid storage tank 1 is connected to an air pressure equalization tube 101, which is connected to the interior of the liquid storage tank 1. Each air pressure equalization tube 101 is installed at the end away from the liquid storage tank 1. An air filter (not shown) is installed. The provision of the air pressure equalization tube 101 can eliminate the resistance of negative pressure liquid suction and ensure the flow stability of the metering pump 2. The purpose of providing the air filter is to prevent dust and other impurities in the external environment from entering the liquid storage tank 1 and damaging the liquid medicine.

[0053] In this embodiment, if Figure 3As shown, the coating part includes a fixed frame 9, a first connecting rod, a second connecting rod, a first loading frame 10, a second loading frame 11 and two sponge blocks. The fixed frame 9 is fixedly installed on the inner wall of the sealing shell 3. One end of the first connecting rod is connected to the fixed frame 9, and the other end thereof is connected to the second connecting rod. The second connecting rod is vertically arranged, and the first connecting rod is horizontally arranged. The first loading frame 10 and the second loading frame 11 are respectively fixed at the upper and lower ends of the second connecting rod, and the first loading frame 10 and the second loading frame 11 are parallel.

[0054] Furthermore, the first loading frame 10 and the second loading frame 11 are both circular frames, and multiple threaded holes are opened at the four edges of the circular frames. A locking screw is installed in the thread of each threaded hole. The two sponge blocks are respectively placed on the first loading frame 10 and the second loading frame 11, and the edges of the sponge blocks are fixed with the locking screws.

[0055] In this embodiment, if Figure 3 As shown, the infusion tube includes an infusion main pipe 4 and an infusion branch pipe 401, both of which are plastic hoses. One end of the infusion main pipe 4 extends into the mixer 12, and the other end thereof is aligned with the sponge block on the first loading frame 10. One end of the infusion branch pipe 401 is connected to an opening on the side wall of the infusion main pipe, and the other end thereof is fixed to the second loading frame 11 and aligned with the sponge block on the second loading frame 11. It should be noted that the distance between the two sponge blocks is slightly less than the thickness of the drip irrigation tape. In this way, when the drip irrigation tape passes between the two sponge blocks, the sponge blocks will lightly press the drip irrigation tape, thereby fully contacting the surface of the drip irrigation tape.

[0056] It should be clear that the thickness of the flat drip irrigation tape usually has a variety of specifications, the most common ones are 0.2-0.6mm, 0.3-0.9mm, 0.4-1.2mm, etc. In this embodiment, the width of the gap between the two sponge blocks can be adjusted by replacing sponge blocks of different thicknesses to adapt to drip irrigation tapes of different thicknesses.

[0057] In some embodiments, two coating members are provided, arranged along the length of the sealed housing 3. Accordingly, two infusion tubes are also provided. Furthermore, the peristaltic pump is a multi-channel peristaltic pump 14, capable of driving both infusion tubes simultaneously to supply liquid medicine to the sponge blocks on both coating members. This double coating process achieves a better coating effect and increases the thickness of the liquid medicine coating.

[0058] In the embodiment, the hot air curing mechanism comprises a hot air blower 6, a curing cylinder 5 and a hot air pipe 601. The curing cylinder 5 is in a cylindrical shape, has opposite inlets and outlets, and is connected to the outlet of the sealing shell 3. The outlet of the curing cylinder 5 is connected to the outside environment. A circular ring pipe is installed in the curing cylinder 5, and a plurality of air outlets are evenly arranged on the circular ring pipe along the axis of the circular ring pipe. One end of the hot air pipe 601 is connected to the hot air blower 6, and the other end of the hot air pipe 601 is connected to the circular ring pipe in the curing cylinder 5.

[0059] It should be noted that the drip irrigation belt passes through the circular ring pipe. After the hot air blower 6 is started, the hot air blower 6 delivers hot air to the circular ring pipe through the hot air pipe 601, and then the hot air is blown out from the plurality of air outlets on the circular ring pipe at different angles to achieve better curing effect.

[0060] In some embodiments, a temperature sensor is installed in the curing cylinder 5, and the temperature sensor is connected to the control system to detect the temperature in the curing cylinder 5 in real time. In this way, the power of the hot air blower 6 can be adjusted in real time according to the temperature detected by the temperature sensor to adjust the temperature in the curing cylinder 5.

[0061] Optionally, the hot air curing mechanism can be replaced by an ultraviolet curing device.

[0062] In addition, the insect repellent liquid used in the embodiment is preferably selected to have a high boiling point and low volatility, so that the overall evaporation rate of the insect repellent liquid is slowed down. For example, the boiling points of phoxim, aldicarb and synthetic capsaicin are 362.5℃, 306.8℃ and 200-210℃, respectively. In this way, the insect repellent liquid on the drip irrigation belt is not easy to evaporate when the insect repellent liquid is cured.

[0063] In addition, a film-forming aid can be added to the mixer 12. The addition of the film-forming aid can form a tough film on the surface of the drip irrigation belt, increase the adhesion of the insect repellent liquid to the drip irrigation belt, and reduce the evaporation of the active ingredients in the insect repellent liquid. For example, some high-boiling polyhydric alcohol compounds can be added to the insect repellent liquid as a film-forming aid.

[0064] In the embodiment, the sealing shell 3 comprises a bottom shell 301 and a top cover 302. The top cover 302 and the bottom shell 301 are detachably connected, for example, by bolt connection. The bottom shell 301 of the sealing shell 3 is fixedly installed on the support frame 8.

[0065] In some embodiments, the anti-bite drip irrigation belt coating device further comprises an exhaust mechanism, which comprises an exhaust pipe 7, an air extractor and an activated carbon adsorption tower. An air outlet is formed on the top cover 302. One end of the exhaust pipe 7 is attached to the top cover 302 and covers the air outlet of the top cover 302. An air extractor is installed inside the end of the exhaust pipe 7 close to the top cover 302. The other end of the exhaust pipe 7 is connected to the activated carbon adsorption tower. The exhaust mechanism is used to treat a small amount of volatile organic compounds in the sealed shell 3, and the emission concentration is less than 20 mg / m 3 , which meets the atmospheric pollutant comprehensive emission standard.

[0066] In some embodiments, an online thickness measuring instrument is installed above the top cover 302. The online thickness measuring instrument uses a 650 nm laser line scanning with a resolution of 0.1 μm and collects 1000 points of data per second. The online thickness measuring instrument is used to measure the thickness of the anti-bite liquid on the drip irrigation belt in real time.

[0067] In summary, in this embodiment, when the anti-bite drip irrigation belt coating device is used to coat the drip irrigation belt with anti-bite liquid, the drip irrigation belt at the punching device is first pulled into the anti-bite drip irrigation belt coating device, and one end of the drip irrigation belt passes through the feed port 303, the gap between the two sponge blocks in the coating member, the discharge port and the curing cylinder 5 in turn, and then the one end of the drip irrigation belt is pulled into the winding device.

[0068] The phoxim, synthetic capsaicin and fenhexamid are respectively put into the three liquid storage tanks 1, and then the propeller stirrers on the liquid storage tanks 1 are started. Then the three metering pumps 2 are turned on, and the phoxim, synthetic capsaicin and fenhexamid are sent into the mixer 12 according to a certain mass fraction ratio. Then the second stirrer 13 on the mixer 12 is turned on, and after stirring for a period of time, the peristaltic pump is turned on to pump the synthetic liquid in the mixer 12 into the liquid delivery pipe. The synthetic liquid flows into the two sponge blocks through the liquid delivery main pipe 4 and the liquid delivery branch pipe 401. Then the air heater 6 and the winding device are turned on. With the opening of the winding device, the drip irrigation belt passes through the gap between the two sponge blocks during the movement, and the sponge blocks lightly press the drip irrigation belt to coat the synthetic liquid on the surface of the drip irrigation belt. At the same time, the hot air blown by the air heater 6 surrounds the drip irrigation belt to achieve rapid curing of the coating.

[0069] It can be seen that the use of the anti-bite drip irrigation belt coating device has at least the following advantages:

[0070] First, as the drip tape passes through the gap between the two sponge blocks, the sponge blocks gently press down on the tape, evenly coating the synthetic liquid across its surface. Compared to manual spraying of insect repellent, this method ensures a uniform coating of the repellent across the tape, avoiding the potential for uneven distribution of the repellent with manual spraying, resulting in excessive amounts of repellent in some areas, which can cause waste or negatively impact crops, and insufficient amounts in others, leading to ineffective insect control.

[0071] Second, the entire coating process is automated. From feeding the drip tape, mixing and applying the insect repellent, to curing and winding, a series of operations can be performed continuously. This greatly improves work efficiency compared to the traditional method of manual inspection, repair, and spraying. Manual operations require a lot of time and manpower to inspect the drip tape for damage and perform repairs or spraying. This equipment can complete the insect repellent coating process simultaneously during the production or installation of the drip tape.

[0072] Third, while the equipment itself may require a certain initial investment, it can save costs in the long run. Compared with frequent manual repairs and material replacement, this equipment can effectively reduce the frequency of damage to drip irrigation tape due to pests, extending the service life of the drip irrigation tape, thereby reducing the frequency of drip irrigation system updates and maintenance, and reducing labor and material costs.

[0073] Fourth, through precise mixing and uniform application, excessive use of insect repellent can be avoided. Compared with traditional spraying methods, this method does not spray large amounts of insect repellent into the soil and surrounding environment, reducing the risk of disrupting the balance of soil microorganisms and reducing chemical pollution to the surrounding ecological environment.

[0074] Fifth, the entire process of mixing, conveying, and applying the insect repellent is carried out in a relatively closed environment inside the equipment, reducing the chance of direct contact between operators and the insect repellent and the risk of poisoning due to exposure to toxic chemicals. It is safer than traditional manual spraying methods.

[0075] Sixth, this equipment applies the insect repellent liquid to the surface of the drip irrigation tape. Unlike the production method of drip irrigation tape that mixes the insect repellent liquid into the masterbatch, there is no chemical reaction between the insect repellent liquid and the masterbatch ingredients such as polyethylene and anti-aging agents. This can avoid problems such as loss of mechanical strength, brittleness, and accelerated aging of the drip irrigation tape, thereby ensuring the stability and durability of the drip irrigation tape.

[0076] Example 2:

[0077] A second embodiment of the present invention provides a method for producing an insect bite-proof drip irrigation tape, using the insect bite-proof drip irrigation tape coating device of the first embodiment, including the following steps:

[0078] First step: pull the drip irrigation tape at the punching device into the insect bite-proof drip irrigation tape coating device, and make one end of the drip irrigation tape pass through the inlet 303, the gap between the two sponge blocks in the coating member, the outlet, and the curing cylinder 5 in turn, and then pull one end of the drip irrigation tape into the winding device.

[0079] Second step: put phoxim, synthetic capsaicin and aldicarb into the three liquid storage tanks 1 respectively, and then start the propeller stirrers on the liquid storage tanks 1.

[0080] Third step: start the three metering pumps 2, which respectively send phoxim, synthetic capsaicin and aldicarb into the mixer 12 according to a certain mass fraction ratio, and then start the first stirrer 102 on the mixer 12 to stir for a set time.

[0081] Fourth step: start the peristaltic pump to pump the synthetic liquid in the mixer 12 into the infusion pipe, and the synthetic liquid flows into the two sponge blocks through the infusion main pipe 4 and the infusion branch pipe 401 respectively.

[0082] Fifth step: start the air heater 6, the winding device and the air extractor.

[0083] It should be noted that the ratio of phoxim, synthetic capsaicin and aldicarb is different for different crops. The underground pests of wheat planting include wireworms, beetles and mice; the underground pests of corn planting include wireworms (seedling stage damage rate > 5%) and two-point night moths (3rd instar larvae > 1 head / m 2 ). The underground pests of soybean planting include grubs: density exceeding 3 heads / m 2 need to be controlled, wireworms: density exceeding 5 heads / m 2 need to be controlled. When planting cotton, cotton bollworm larvae eat cotton bolls, although they do not directly damage the drip irrigation tape, but when the pest outbreak is high, frequent field management may increase the risk of mechanical damage to the drip irrigation tape (hundred plants egg amount > 15 grains need to be controlled), and stink bugs (hundred plants insect amount > 5 heads need to be controlled).

[0084] After a large number of experimental demonstrations, when coating the drip irrigation tape special for wheat planting, the liquid ratio is controlled at: phoxim (0.8%) + aldicarb (0.2%) + synthetic capsaicin (1.2%), the damage rate of the drip irrigation tape is the lowest.

[0085] When coating the drip irrigation tape special for corn planting, the liquid ratio is controlled at: phoxim (1.2%) + aldicarb (0.4%) + synthetic capsaicin (1.5%), the damage rate of the drip irrigation tape is the lowest.

[0086] When coating the drip irrigation tape special for soybean planting, the liquid ratio is controlled at: phoxim (0.9%) + aldicarb (0.4%) + synthetic capsaicin (1.1%), the damage rate of the drip irrigation tape is the lowest.

[0087] When applying the drip irrigation tape specially used for cotton planting, the liquid ratio is: phoxim (1.3%) + aldicarb (0.3%) + synthetic capsaicin (1.4%).
