Description

Technical Field

[0001] This utility model relates to the technical field of indoxacarb screening equipment, and specifically discloses a screening equipment for the production of indoxacarb technical. Background Technology

[0002] Indoxacarb is a broad-spectrum diazinon insecticide, belonging to the sodium ion channel blocking neurotoxin class. It is mainly used for the control of agricultural and sanitary pests. Indoxacarb is effective against a variety of lepidopteran pests, including cabbage caterpillars, diamondback moths, red imported fire ants, and cotton bollworms. Indoxacarb is characterized by its broad-spectrum, high efficacy, and high safety, and is widely used for pest control in vegetables, fruit trees, cotton, rice, and tea trees. During the processing of indoxacarb, screening equipment is usually used to sieve the indoxacarb technical powder to remove large particles and impurities.

[0003] Chinese patent CN221183591U discloses a screening device for the production of indoxacarb technical, relating to the field of screening equipment. The device includes a storage box for storing filtered indoxacarb technical. The top of the storage box is equipped with a screening component, which includes a storage cylinder. A second motor is installed at the top of the storage cylinder. A support plate is provided inside the storage cylinder, and a screw threaded through the support plate. A sleeve is threaded onto the bottom of the storage cylinder. Vertical plates are provided on both sides of the storage box, and an adjusting shaft is installed on the side of each vertical plate facing the screening component via bearings. This invention controls the rotation of the storage cylinder and drives the screw to rotate via a second motor, causing the pallet to approach the opening of the storage cylinder. This reduces the depth of the storage cylinder during the pouring of indoxacarb technical, thus minimizing the drop height of the indoxacarb and preventing dust from being stirred up and harming health. However, in the above-mentioned screening equipment, after the indoxacarb technical in the storage cylinder is screened, the sleeve needs to be separated from the technical before adding new indoxacarb technical to be screened. During the disassembly and reassembly of components such as the sleeve and corrugated pipe, residual indoxacarb powder on these components can easily fall onto the outside of these components, increasing the risk of contact for users and affecting the continuity of indoxacarb screening, thereby reducing the efficiency of indoxacarb screening. Therefore, to solve the above problems, this invention proposes a screening device for indoxacarb technical production. Utility Model Content

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-5 This application will be described in detail with reference to the embodiments.

[0025] This embodiment discloses a screening device for the production of indoxacarb technical grade, including a support mechanism 1 and a screening mechanism 2. The screening mechanism 2 is arranged on the upper inner side of the support mechanism 1. The support mechanism 1 includes a support frame 11. Two mounting blocks 111 are symmetrically arranged at both ends of the lower part of the support frame 11. Telescopic rods 14 are arranged below each of the four mounting blocks 111. The screening mechanism 2 includes a screen box 21. A screen plate 211 is connected to the inner side of the screen box 21. A top plate 22 and a discharge hopper 23 are respectively connected to the upper and lower ends of the screen box 21. A feed pipe 221 and a discharge pipe 231 are respectively connected to the side of the top plate 22 and the discharge hopper 23 away from the screen box 21. Support plates 24 are connected to both ends of the screen box 21. A cam 27 is arranged in the middle of the lower part of each of the two support plates 24. Multiple springs 25 arranged in a linear array are arranged on both sides of the cam 27.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, support legs 12 are symmetrically connected to both ends of the lower part of the support frame 11, which can provide stable support for the support frame 11 and the components above it. A base 13 is provided between the two support legs 12 at the same end. Both ends of the base 13 are connected to baffles 131. The baffles 131 are close to the support legs 12 to facilitate the alignment of the base 13 and the mounting block 111. A mounting plate 15 is connected to the lower part of the telescopic rod 14. The mounting plate 15 is detachably connected to the connecting plate. A connector 141 is provided at the telescopic end of the telescopic rod 14. The connector 141 is detachably connected to the mounting block 111 to facilitate the disassembly and assembly of the mounting plate 15 and the telescopic rod 14 above it.

[0027] like Figure 1 and Figure 4As shown, the feed pipe 221 and discharge pipe 231 are respectively detachably connected to the first corrugated pipe 222 and the second corrugated pipe 232 at the ends away from the screen box 21, which facilitates connection with the original feeding device and receiving device, and ensures that the screen box 21 and its connecting parts squeeze and stretch the first corrugated pipe 222 and the second corrugated pipe 232 during the up and down movement, so as to ensure that the indoxacarb technical material can smoothly enter and exit the screen box 21.

[0028] like Figure 1 and Figure 5 As shown, the two ends of the spring 25 are connected to the support plate 24 and the support frame 11 respectively, which facilitates the installation and maintenance of the spring 25. The spring 25 is provided with a guide rod 26 inside. The guide rod 26 passes through the inside of the support plate 24 and is slidably connected to the support plate 24. It can limit the movement direction of the support plate 24 and the screen box 21, so that the support plate 24 and the screen box 21 can move up and down stably.

[0029] like Figure 1 and Figure 5 As shown, one end of the cam 27 is connected to a motor 28, which enables the motor 28 to drive the cam 27 to rotate during operation. A base 281 is provided on the outside of the motor 28, and the lower end of the base 281 is connected to the support frame 11, which can provide stable support for the motor 28 and facilitate the installation and maintenance of the motor 28.

[0030] like Figure 1 As shown, a controller 3 is provided at one end of the support mechanism 1 to facilitate the control of the operation of the relevant components in the device.

[0031] The sieving equipment for indoxacarb technical production disclosed in this embodiment involves connecting the ends of the first corrugated pipe 222 and the second corrugated pipe 232 away from the sieve box 21 to the existing feeding device and receiving device, respectively, before use. The indoxacarb technical powder to be sieved is injected into the sieve box 21 through the first corrugated pipe 222 and the feed pipe 221. The controller 3 simultaneously starts two motors 28, causing them to drive the cam 27 to rotate. During rotation, the cam 27 repeatedly contacts the support plate 24, pushing the support plate 24 and the sieve box 21 upwards, stretching the spring 25, and causing the guide rod 26 to slide inside the support plate 24. The first bellows 222 is compressed and the second bellows 232 is stretched. When the cam 27 separates from the support plate 24, the support plate 24 and the sieve box 21 and other components move downward due to gravity, squeezing the spring 25. The second bellows 232 is compressed and the first bellows 222 is stretched, thereby realizing the reciprocating movement of the sieve box 21. The indoxacarb technical powder above the sieve plate 211 in the sieve box 21 is sieved. The sieved indoxacarb technical powder falls through the sieve holes in the sieve plate 211 into the hopper 23, and is discharged into the original receiving device through the discharge pipe 231 and the second bellows 232. The user does not need to come into contact with indoxacarb during the whole process.

[0032] After a period of time, separate the first corrugated pipe 222 from the feed pipe 221, remove the top plate 22 from above the sieve box 21, clean the sieve plate 211 and the top plate 22, reset the top plate 22, and restore the connection between the first corrugated pipe 222 and the feed pipe 221. The screening operation of indoxacarb technical can then continue. When it is necessary to adjust the distance between the discharge pipe 231 and the ground, place the two bases 13 with two telescopic rods 14 on them between the two support legs 12 at the same end, so that the baffle 131 is close to the support leg 12. At this time, the connector 141 at the telescopic end of the telescopic rod 14 is aligned with the mounting block 111. Connect the signal line and power line of the telescopic rod 14. Connect to controller 3 and use controller 3 to simultaneously control the extension of four telescopic rods 14. When the connector 141 contacts the mounting block 111, connect the connector 141 to the mounting block 111 together. Continue to control the extension of telescopic rods 14 to lift the support frame 11 and screening mechanism 2 upward, so that the support leg 12 is separated from the ground. The telescopic rods 14 and base 13 provide support for the support frame 11 and its connecting parts, thereby increasing the distance between the discharge pipe 231 and the ground. After the adjustment is completed, use controller 3 to close the four telescopic rods 14 at the same time, so that the user can disassemble and install the second corrugated pipe 232 and connect the lower end of the second corrugated pipe 232 to the original receiving device.

[0033] The components disclosed in this utility model for screening equipment used in the production of indoxacarb technical material, including controller 3, mounting block 111, support leg 12, base 13, telescopic rod 14, connector 141, sieve box 21, sieve plate 211, top plate 22, first corrugated pipe 222, hopper 23, second corrugated pipe 232, support plate 24, spring 25, guide rod 26, cam 27, and motor 28, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
