Description

Technical Field

[0001] The present application relates to the field of pesticide production, and in particular to a pesticide-fertilizer co-seeding production device and granules for controlling soybean bee stink bugs. Background Art

[0002] Soybean is a leguminous plant rich in oil, high-quality protein, unsaturated fatty acids, and a variety of trace elements. It is most commonly used to make various soy products, press soybean oil, refine soy sauce, and extract protein. Bean dregs or soybeans ground into coarse powder are also commonly used as livestock feed. The bee-sucking stink bug is a common piercing and sucking pest in soybean fields. It often causes damage during the soybean pod-setting period, resulting in yield losses.

[0003] Spreading pesticides and fertilizers into soybean fields is one way to control bee-margin bugs. In related technologies, spreading fertilizers and seeds at the same time is a convenient way to spread granular pesticides. Spreading fertilizers and seeds at the same time means that a certain proportion of fertilizer granules are spread simultaneously during the sowing process, with uniform quantity and density distribution. During the growth cycle of crops, the efficacy of the fertilizer granules is slowly released and takes effect.

[0004] Since the crop growth cycle is long (soybean pod formation usually occurs about 30-45 days after soybean flowering), the required sustained-release time is also long, but the current fertilizer granules have a short release cycle and cannot meet the demand. Summary of the invention

[0005] In order to improve the above problems, the present application provides a co-seeding pesticide and fertilizer production device and granules for controlling soybean bee-margin stink bugs.

[0006] The present application provides a device for producing pesticides and fertilizers for controlling soybean bee stink bugs, which adopts the following technical solution: A co-seeding fertilizer production device for controlling soybean bee-margin bugs comprises a machine chamber and a coating mechanism, wherein the coating mechanism is located in the machine chamber, and an inlet and an outlet are respectively provided on the machine chamber, and the fertilizer particles enter the machine chamber through the inlet and leave the machine chamber through the outlet, and the coating mechanism comprises a plurality of processing units, and the fertilizer particles pass through each processing unit in sequence, and each processing unit comprises a coating module and a drying module, wherein the coating module is used for spraying coating materials onto the surface of the fertilizer particles, and the drying module is used for drying the surface of the fertilizer particles.

[0007] By adopting the above technical scheme, the medicinal fertilizer particles pass through various processing units, and are spray-coated and dried in turn, and finally the medicinal fertilizer particles with multiple coating layer structures formed on the surface are obtained, which have a higher sustained-release effect and better adapt to the growth cycle of soybeans.

[0008] Preferably, the feed inlet is located at the top of the machine bin, the discharge port is located at the bottom of the machine bin, the multiple processing units are arranged vertically, the coating module includes a spray pipe, a guide slope and a friction component, the nozzle of the spray pipe faces the slope of the guide slope, the medicine and fertilizer particles roll obliquely downward along the slope of the guide slope, the friction component includes a resistance member, the resistance member is movably connected to the guide slope, the resistance member contacts the medicine and fertilizer particles and generates a rolling friction force on the medicine and fertilizer particles obliquely upward along the guide slope.

[0009] Preferably, the resistance member is a friction soft belt, and the friction assembly also includes a guide roller, which is rotatably connected to the machine chamber, and the friction soft belt is wound around the roller surface of the guide roller. The friction soft belt moves along the slope of the guide slope, and the moving direction is obliquely upward. The fertilizer particles are located on the side surface of the friction soft belt away from the guide slope.

[0010] By adopting the above technical solution, during the rolling process of the medicinal fertilizer particles, the friction soft belt contacts the medicinal fertilizer particles and generates a rolling friction force on the medicinal fertilizer particles obliquely upward along the guide slope, thereby reducing the overall speed of the medicinal fertilizer particles passing through the guide slope and extending the residence time of the medicinal fertilizer particles on the guide slope, thereby increasing the adhesion amount and uniformity of the coating material on the surface of the medicinal fertilizer particles.

[0011] Preferably, the coating mechanism further includes a flow control component, which is located in the machine bin and below the feed port, and the flow control component includes a slope plate, and a bucket-shaped space for the medicine and fertilizer particles to pass through is formed between the slope plate and the top guide slope, and the width of the bucket-shaped space gradually decreases in the downward direction.

[0012] By adopting the above technical solution, after a large number of fertilizer particles enter the machine chamber from the feed port, the bucket-shaped space can make a large number of fertilizer particles fall on the friction soft belt more orderly, relatively reduce the density of the fertilizer particles rolling on the friction soft belt, and improve the spraying sufficiency of each fertilizer particle.

[0013] Preferably, the flow control component includes an auxiliary roller, which is located at the bottom of the bucket-shaped space and is rotatably connected to the machine chamber, and the movement trend of the auxiliary roller on the side close to the friction soft belt is opposite to the moving direction of the friction soft belt.

[0014] By adopting the above technical solution, after passing through the gap between the auxiliary roller and the friction soft belt, the friction forces generated by the friction soft belt and the auxiliary roller on the fertilizer particles are in opposite directions, so that each fertilizer particle can obtain a certain rolling tendency, and the uniformity of the spraying on its surface can also be improved.

[0015] Preferably, the friction assembly includes a tensioning roller, an extrusion roller and a receiving trough body, the tensioning roller and the extrusion roller are both rotatably connected to the machine chamber, the tensioning roller is located below the guide slope, and the friction soft belt bypasses the tensioning roller, the extrusion roller is located on the side of the friction soft belt away from the tensioning roller, the extrusion roller and the tensioning roller abut against the opposite sides of the friction soft belt, the receiving trough body is located below the extrusion roller, and a collecting trough is provided above the receiving trough body; a water collecting annular groove is provided on the side wall of the extrusion roller, and the water collecting annular groove is spirally arranged around the extrusion roller, a contact soft film is fixedly connected to the groove wall of the collecting trough, and the contact soft film is in contact with the side wall of the extrusion roller.

[0016] By adopting the above technical solution, the friction soft belt has elasticity. When the spray pipe sprays liquid coating material, most of the liquid will adhere to the surface of the friction soft belt. When the tensioning roller and the squeezing roller produce squeezing effect on the friction soft belt, the liquid attached to the friction soft belt will be squeezed out, thereby flowing down along the water collecting ring groove and finally falling into the collecting tank for recovery. The contact soft film contacts the side wall of the squeezing roller to improve the smoothness of the liquid falling from the squeezing roller.

[0017] Preferably, the drying module includes a hot air duct, a hollow baffle and an air pass plate, the hollow baffle and the air pass plate are provided with holes, and the fertilizer particles pass between the hollow baffle and the air pass plate. The hot air duct is located on the side of the hollow baffle away from the air pass plate, and the hot air duct sprays air toward the hollow baffle.

[0018] By adopting the above technical solution, the gaps on the hollow baffle plate and the air pass plate allow air flow to pass smoothly, and at the same time, the fertilizer particles with a diameter larger than the hole diameter will not overflow.

[0019] Preferably, the movement direction of the fertilizer particles between the hollow baffle plate and the air flow plate is vertically downward, the air flow direction applied by the hot air pipe is perpendicular to the movement direction of the fertilizer particles, a plurality of particle-blocking sill bars are provided on the side of the air flow plate facing the hollow baffle plate, the length direction of the particle-blocking sill bars is perpendicular to the movement direction of the fertilizer particles, the arrangement direction of the plurality of particle-blocking sill bars is consistent with the movement direction of the fertilizer particles, an empty frame rod is provided on the air flow plate and reciprocates between two adjacent particle-blocking sill bars, the length direction of the empty frame rod is consistent with the length direction of the particle-blocking sill bars, and the sliding direction is perpendicular to the plate surface of the air flow plate, a push rod is fixedly connected to the empty frame rod, the push rod passes through the air flow plate and slides relative to it, and the drying module also includes a control component for moving the push rod.

[0020] By adopting the above technical solution, when the medicinal fertilizer particles between the hollow baffle plate and the air pass plate are affected by the airflow perpendicular to the moving direction, they will be blown onto the empty frame rod and stuck between two adjacent particle-blocking sills. This arrangement increases the residence time of the medicinal fertilizer particles here and improves the drying effect. When the empty frame rod moves, the medicinal fertilizer particles between the two particle-blocking sills can be pushed out, so that the medicinal fertilizer particles can continue to move forward.

[0021] Preferably, the control component includes a return spring and a transmission belt mechanism, one end of the return spring is connected to the push rod, and the other end is connected to the wind plate, and a toggle block is fixedly connected to the transmission belt of the transmission belt mechanism, and when the toggle block moves vertically upward with the transmission belt, the toggle block abuts against each push rod.

[0022] By adopting the above technical solution, under the action of the toggle block, the empty frame rods from bottom to top move back and forth in sequence to push the fertilizer particles. The fertilizer particles at each height enter the particle-blocking threshold of the next height after one push, and finally all the fertilizer particles are below the lowest particle-blocking threshold.

Through the setting of the friction soft belt, when the fertilizer particles slide down the guide slope, the friction soft belt moves in the opposite direction of the movement of the fertilizer particles, generating resistance to the fertilizer particles, so that the fertilizer particles can stay on the guide slope longer and the surface is sprayed more fully.

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] The present application embodiment discloses a co-seeding fertilizer production device for controlling soybean bee-margin bugs, such as Figure 1 As shown, it includes a machine chamber 1 and a coating mechanism 13 located in the machine chamber 1; the machine chamber 1 is provided with an inlet 11 at the top and an outlet 12 at the bottom, and the medicine fertilizer particles are added into the machine chamber 1 through the inlet 11, and the coating mechanism 13 coats the medicine fertilizer particles, and the treated medicine fertilizer particles leave the machine chamber 1 through the outlet 12. The coating mechanism 13 includes a plurality of processing units arranged vertically in sequence, and the medicine fertilizer particles pass through each processing unit in sequence, and each processing unit includes a coating module 2 and a drying module 4 along the direction of movement of the medicine fertilizer particles; the coating module 2 is used to spray the coating material on the surface of the medicine fertilizer particles, and the drying module 4 is used to dry the surface of the medicine fertilizer particles. During the use of the equipment, a single processing unit can form a layer of surface coating material on the outside of the medicine fertilizer particles. In this embodiment, the number of processing units is two, that is, it can produce medicine fertilizer particles with a two-layer coating material layer structure.

[0032] like Figure 1As shown, the coating module 2 includes a spray pipe 21, a guide slope 22 and a friction assembly 23. The guide slope 22 and the spray pipe 21 are both fixedly connected to the machine chamber 1. The guide slope 22 of the coating module 2 of the uppermost processing unit is located below the feed port 11, and the slope surface is inclined downward, that is, the drug fertilizer particles falling from the feed port 11 will roll obliquely downward along the guide slope 22; the nozzle of the spray pipe 21 faces the slope surface of the guide slope 22, and the spray pipe 21 sprays liquid coating material toward the drug fertilizer particles on the guide slope 22. The friction assembly 23 includes a resistance member 231, which is movably connected to the guide slope 22. The resistance member 231 is used to increase the resistance of the drug fertilizer particles in the process of rolling along the guide slope 22, so as to prolong the retention time of the drug fertilizer particles on the guide slope 22, thereby increasing the adhesion amount and uniformity of the coating material on the surface of the drug fertilizer particles. The friction assembly 23 also includes a guide roller 232. There are two guide rollers 232, both of which are rotatably connected to the machine chamber 1. The two guide rollers 232 are respectively located at the upper and lower ends of the guide slope 22. The resistance member 231 is a friction soft belt. A power source (not shown in the figure) for driving the guide roller 232 to rotate is provided in the machine chamber 1. The friction soft belt is wound around the roller surface of the guide roller 232. The friction soft belt moves along the slope of the guide slope 22 and the moving direction is obliquely upward. The medicinal fertilizer particles are located on the side surface of the friction soft belt away from the guide slope 22. In the process of the medicinal fertilizer particles rolling down, the friction soft belt contacts the medicinal fertilizer particles and generates a rolling friction force obliquely upward along the guide slope 22 on the medicinal fertilizer particles, thereby reducing the overall speed of the medicinal fertilizer particles passing through the guide slope 22.

[0033] like Figure 1 and 2 As shown, the material of the friction belt in this embodiment is rubber. When the spray pipe 21 sprays the liquid coating material, most of the liquid will adhere to the surface of the friction belt. The friction assembly 23 includes a tensioning roller 233, a squeezing roller 234 and a receiving tank 235. The tensioning roller 233 and the squeezing roller 234 are both rotatably connected to the machine chamber 1. The tensioning roller 233 is located below the guide slope 22, and the friction belt bypasses the tensioning roller 233; the squeezing roller 234 is located on the side of the friction belt away from the tensioning roller 233, and the squeezing roller 234 and the tensioning roller 233 are in contact with the opposite sides of the friction belt. The receiving tank 235 is located below the squeezing roller 234, and a collecting tank 2351 is provided above the receiving tank 235. A water collecting annular groove 2341 is provided on the side wall of the squeezing roller 234, and the water collecting annular groove 2341 is arranged spirally around the squeezing roller 234. When the tension roller 233 and the squeezing roller 234 exert squeezing action on the friction soft belt, the liquid material attached to the friction soft belt will be squeezed out, and then flow down along the water collecting annular groove 2341, and finally fall into the collecting groove 2351 for recovery. A contact soft sheet 2352 is fixedly connected to the groove wall of the collecting groove 2351, and the contact soft sheet 2352 contacts the side wall of the squeezing roller 234 to improve the smoothness of the liquid material falling from the squeezing roller 234.

[0034] like Figure 1As shown, the coating mechanism 13 also includes a flow control component 3, which is located in the machine chamber 1 and below the feed port 11. The flow control component 3 includes a ramp plate 31 and an auxiliary roller 32. A bucket-shaped space for the drug fertilizer particles to pass through is formed between the ramp plate 31 and the uppermost guide slope 22. The width of the bucket-shaped space gradually decreases in the downward direction. After a large number of drug fertilizer particles enter the machine chamber 1 from the feed port 11, the bucket-shaped space can make a large number of drug fertilizer particles fall on the friction soft belt more orderly, relatively reduce the density of the drug fertilizer particles rolling on the friction soft belt, and improve the spraying sufficiency of each drug fertilizer particle. The flow control component 3 includes an auxiliary roller 32, which is located at the bottom of the bucket-shaped space and is rotatably connected to the machine chamber 1. The movement trend of the auxiliary roller 32 on the side close to the friction soft belt is opposite to the moving direction of the friction soft belt (a driving power source for driving the auxiliary roller 32 to rotate is provided inside the machine chamber 1). The diameter of the fertilizer particles entering the feed port 11 is in the range of 4-6 mm, and the minimum spacing between the auxiliary roller 32 and the friction soft belt surface is 6 mm. After passing through the gap between the auxiliary roller 32 and the friction soft belt, each fertilizer particle can obtain a certain rolling tendency, and the uniformity of the spraying on its surface can also be improved.

[0035] like Figure 1 and 3As shown, the drying module 4 includes a hot air duct 41, a hollow baffle 42 and an air plate 43, all of which are fixedly connected to the machine room 1. The hot air duct 41 is located on the side of the hollow baffle 42 away from the air plate 43, and the hot air duct 41 sprays air toward the hollow baffle 42. Holes are densely distributed on the hollow baffle 42 and the air plate 43. The size of these holes is less than 3mm, allowing the airflow to pass fully without causing the fertilizer particles to overflow. A gap is formed between the hollow baffle 42 and the air plate 43 for the fertilizer particles to pass through, and the movement direction of the fertilizer particles between the two is vertically downward. The airflow direction is horizontal. A plurality of particle-blocking sills 431 are integrally formed on one side of the air-passing plate 43 facing the hollow baffle plate 42. The length direction of the particle-blocking sills 431 is perpendicular to the moving direction of the fertilizer particles. The arrangement direction of the plurality of particle-blocking sills 431 is consistent with the moving direction of the fertilizer particles. An empty frame rod 44 is provided on the air-passing plate 43 and reciprocates and slides between two adjacent particle-blocking sills 431. The empty frame rod itself is a hollow rod-shaped structure. The length direction of the empty frame rod 44 is consistent with the length direction of the particle-blocking sills 431. The sliding direction is perpendicular to the plate surface of the air-passing plate 43. A push rod 441 is fixedly connected to the empty frame rod 44. The push rod 441 passes through the air-passing plate 43 and slides relative to it. When the fertilizer particles between the hollow baffle plate 42 and the air-passing plate 43 are affected by the horizontal airflow, they will be blown to the empty frame rod 44 by the airflow and stuck between two adjacent particle-blocking sills 431. Such a setting increases the retention time of the fertilizer particles here and improves the drying effect. The drying module 4 also includes a control component 45 for moving the push rod 441. The side of the empty frame rod 44 and the particle-blocking sill 431 facing the hollow baffle 42 are both inclined profiles. The empty frame rod 44 moves away from the air plate 43 to push the fertilizer particles out from between two adjacent particle-blocking sills 431.

[0036] like Figure 3 As shown, the control assembly 45 includes a reset spring 451 and a transmission belt mechanism 452. One end of the reset spring 451 is connected to the push rod 441, and the other end is connected to the air plate 43. In the natural state, the empty frame rod 44 abuts against the air plate 43. The transmission belt of the transmission belt mechanism 452 is fixedly connected with a toggle block 453. During the process of the toggle block 453 moving vertically upward with the transmission belt, the toggle block 453 abuts against each push rod 441, that is, each empty frame rod 44 from bottom to top moves back and forth horizontally in turn to push the fertilizer particles. After one push, the fertilizer particles at each height enter the next height of the particle barrier 431. Finally, all the fertilizer particles are lower than the lowest particle barrier 431. There is no airflow here, and the fertilizer particles naturally fall to the coating module 2 of the next processing unit.

[0037] The present application also discloses a co-seeding drug-fertilizer granule for controlling soybean bee-edge bugs produced by the above production device, such as Figure 4As shown, it includes a core particle 5 and a coating layer. The core particle 5 is cyfluthrin•clothianidin, that is, the drug fertilizer particle directly enters the machine chamber 1 through the feed port 11 is the core particle 5, and the ratio of cyfluthrin and clothianidin is 1:3. The coating layer has two layers, namely, a polymer layer 52 and a plant extract active layer 51, and the polymer layer 52 is located outside the plant extract active layer 51. The diameter of the final granule product obtained is 6-8mm.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
