Description

Technical Field

[0001] This utility model relates to the field of grain production technology, specifically to a screening device for grain production with good impurity removal effect. Background Technology

[0002] Grains refer to the seeds of grasses, including rice, wheat, and corn. Grains are a traditional staple food for many Asian people and cover a wide range, mainly including rice, wheat, millet, soybeans, and other miscellaneous grains. Grains can be divided into cereals and legumes. Cereals include rice (indica rice, japonica rice, glutinous rice), wheat (wheat, barley, oats, rye), corn, sorghum, millet, foxtail millet, yellow millet, buckwheat, etc.; legumes include soybeans, broad beans, peas, mung beans, red beans, kidney beans, etc.

[0003] Publication No. CN220004931U discloses a grain seed screening device, which has multiple air plates connected to a rotating shaft. The rotating shaft is connected to the guide roller via a transmission belt, thereby cleaning weeds and fragments from the grain seeds and ensuring the purity of the filtered grain seeds. However, this patent still has the following problems in actual use:

[0004] During grain screening, the grains roll and slide directly out of the device body on the filter plate. However, if there is a large accumulation of grains, some impurities in the grain pile may not be screened out and will be discharged from the device body along with the grain pile. As a result, some impurities will still remain in the screened grains, thus affecting the quality of the grains.

[0005] A screening device for grain production with good impurity removal effect is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a grain screening device with good impurity removal effect, in order to solve the problem mentioned in the background art that when screening grains, the grains will roll and slide directly out of the device body on the filter plate. However, if there is a large accumulation of grains, some impurities in the grain pile may not be screened out and will be discharged from the device body with the grain pile, resulting in some impurities remaining in the screened grains, thus affecting the quality of the grains.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a screening device for grain production with good impurity removal effect, comprising a device body and a feed inlet installed on the top of the device body, and a door is provided on the front of the device body;

[0008] Also includes:

[0009] The device body is equipped with a screening component inside. The screening component includes a connecting piece, which is symmetrically fixed inside the device body. A connecting plate is fixedly connected to the top of one of the connecting pieces, and a motor is installed on the front of the connecting plate. A half tooth is fixedly connected to the output end of the motor.

[0010] The device body has a first spring fixedly connected to one side of its interior, a connecting block fixedly connected to one side of the first spring, and a first telescopic rod fixedly connected between the connecting block and the device body.

[0011] The connecting block has a rack fixedly connected to one side, and the rack meshes with a half tooth. A fixing block is fixedly connected to one side of the rack, and a sliding rod is slidably connected inside the fixing block.

[0012] Preferably, a screening cylinder is fixedly connected to one side of the slide rod, and a screen is installed at the bottom of the screening cylinder.

[0013] Preferably, a connecting shell is fixedly connected to one side of the screening cylinder, and a second spring is fixedly connected inside the connecting shell. A second telescopic rod is fixedly connected to the bottom of the second spring, and the side of the second telescopic rod away from the second spring is fixedly connected to the device body.

[0014] Preferably, a plurality of first triangular blocks are symmetrically fixed to the top of the connecting piece, and second triangular blocks are symmetrically fixed to both sides of the screening cylinder, and the first triangular blocks abut against the second triangular blocks.

[0015] Preferably, the screening cylinder is equipped with a cylinder door on the front side, and a slot is provided on the other side of the device body.

[0016] Preferably, a collection component is provided on one side of the device body, the collection component includes a mounting plate, and a collection shell is placed on the top of the mounting plate. A guide block is fixedly connected inside the device body, and a discharge port is provided on the other side of the device body.

[0017] Preferably, the top of the mounting plate is symmetrically fixed with a connecting frame, and the inner side of the connecting frame can rotate; a threaded rod is connected, and a locking block is threadedly connected to the outside of the threaded rod; a limiting rod is fixedly connected between the connecting frame and the mounting plate, and the locking block slides outside the limiting rod; a block is fixedly connected to one side of the collecting shell, and the locking block and the block engage with each other.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this grain screening device with good impurity removal effect can reciprocate and shake the grain for screening, and can make the screening cylinder vibrate while moving, thereby further improving the screening efficiency of the grain. The specific details are as follows:

[0019] 1. When the motor is started, it drives the half-tooth to rotate, which in turn drives the rack to move. The rack then drives the connecting block to move, stretching the first spring. When the half-tooth rotates to a certain extent, it disengages from the rack, at which point the first spring rebounds, causing the rack to reset. When the half-tooth rotates to a certain extent again, it re-engages with the rack, allowing the rack to reciprocate. The rack then drives the fixed block to reciprocate, causing the sliding rod to reciprocate the screening cylinder. This allows the screening cylinder to reciprocate and slide to screen the grains. As the screening cylinder moves, it drives the second triangular block to move. The second triangular block, in conjunction with the first triangular block, causes the screening cylinder to rise. As the screening cylinder rises, the second spring is stretched. When the second triangular block disengages from the first triangular block, the second spring rebounds directly, causing the screening cylinder to drop and generate secondary vibration, further improving the grain screening efficiency.

[0020] 2. The screened grains will fall onto the guide block through the screen, and then into the collection shell. When it is necessary to remove the grains inside the collection shell, the threaded rod can be rotated. The threaded rod will cause the locking block to rise, and the locking block will disengage from the inside of the block, thereby releasing the block's restriction and the collection shell's restriction, making it possible to disassemble the collection shell and easily remove the collected grains.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a grain screening device with good impurity removal effect, comprising a device body 1 and a feed inlet 2 installed on the top of the device body 1, and a door 3 opened on the front of the device body 1; a screening assembly 4 is provided inside the device body 1, the screening assembly 4 includes connecting pieces 401, and the connecting pieces 401 are symmetrically fixed inside the device body 1, and a connecting plate 402 is fixedly connected to the top of one side of the connecting piece 401, and a motor 403 is installed on the front of the connecting plate 402, and the motor 403... The output end is fixedly connected to a half tooth 404; wherein, a first spring 405 is fixedly connected to one side of the inner side of the device body 1, and a connecting block 406 is fixedly connected to one side of the first spring 405, and a first telescopic rod 407 is fixedly connected between the connecting block 406 and the device body 1; wherein, a rack 408 is fixedly connected to one side of the connecting block 406, and the rack 408 meshes with the half tooth 404, a fixing block 409 is fixedly connected to one side of the rack 408, and a slide rod 410 is slidably connected inside the fixing block 409, such as Figure 3As shown, when the motor 403 is started, the motor 403 will drive the half tooth 404 to rotate, the half tooth 404 will drive the rack 408 to move, the rack 408 will drive the connecting block 406 to move, and the connecting block 406 will stretch the first spring 405. When the half tooth 404 rotates to a certain extent, it will disengage from the rack 408. At this time, the first spring 405 will rebound, causing the rack 408 to reset. When the half tooth 404 rotates to a certain extent again, it will re-engage with the rack 408. This process is repeated, allowing the rack 408 to move back and forth. Then the rack 408 drives the fixed block 409 to move back and forth, and then the fixed block 409 drives the slide rod 410 to move back and forth.

[0030] A screening cylinder 411 is fixedly connected to one side of the slide rod 410, and a screen 412 is installed at the bottom of the screening cylinder 411. A connecting shell 414 is fixedly connected to one side of the screening cylinder 411, and a second spring 415 is fixedly connected inside the connecting shell 414. A second telescopic rod 413 is fixedly connected to the bottom of the second spring 415, and the side of the second telescopic rod 413 away from the second spring 415 is fixedly connected to the device body 1. Multiple first triangular blocks 417 are symmetrically fixed to the top of the connecting piece 401, and second triangular blocks 416 are symmetrically fixed to both sides of the screening cylinder 411. Figure 3 , 4 As shown, the slide bar 410 causes the screening cylinder 411 to move back and forth, enabling the screening cylinder 411 to perform reciprocating sliding screening of grains. When the screening cylinder 411 moves, it drives the second triangular block 416 to move. Then, the second triangular block 416, in cooperation with the first triangular block 417, causes the screening cylinder 411 to rise. When the screening cylinder 411 rises, it stretches the second spring 415. When the second triangular block 416 disengages from the first triangular block 417, the second spring 415 will rebound directly, causing the screening cylinder 411 to fall and generate secondary vibration, thereby further improving the screening efficiency of grains. Moreover, the first triangular block 417 and the second triangular block 416 abut against each other. A cylinder door 418 is installed on the front of the screening cylinder 411. The function of the cylinder door 418 is to facilitate opening the screening cylinder 411, thereby facilitating the removal and cleaning of impurities on the screen 412. A slot 419 is provided on the other side of the device body 1.

[0031] A collection component 5 is provided on one side of the device body 1. The collection component 5 includes a mounting plate 501, and a collection shell 502 is placed on the top of the mounting plate 501. A guide block 503 is fixedly connected inside the device body 1. A discharge port 504 is provided on the other side of the device body 1. A connecting frame 505 is symmetrically fixed on the top of the mounting plate 501. The inner side of the connecting frame 505 can rotate. A threaded rod 506 is connected. A locking block 507 is threadedly connected to the outer side of the threaded rod 506. A limiting rod 508 is fixedly connected between the connecting frame 505 and the mounting plate 501. The locking block 507 slides outside the limiting rod 508. A square block 509 is fixedly connected to one side of the collection shell 502. The locking block 507 and the square block 509 are engaged.

[0032] Working principle: Before using this grain screening device with good impurity removal effect, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6 As shown, firstly, grains are fed into the screening cylinder 411 through the feed inlet 2. Then, the motor 403 is started, which drives the half-tooth 404 to rotate. The half-tooth 404 drives the rack 408 to move, which in turn drives the connecting block 406 to move. The connecting block 406 stretches the first spring 405. When the half-tooth 404 rotates to a certain extent, it disengages from the rack 408. At this point, the first spring 405 rebounds, causing the rack 408 to reset. When the half-tooth 404 rotates to a certain extent again, it re-engages with the rack 408, thus repeating the above process, allowing the rack 408 to reciprocate. Then, the rack 408 drives the fixing block 409 to reciprocate. The fixed block 409 drives the slide bar 410 to move back and forth, and the slide bar 410 causes the screening cylinder 411 to move back and forth, so that the screening cylinder 411 can perform reciprocating sliding screening of grains. When the screening cylinder 411 moves, it drives the second triangular block 416 to move. Then, the second triangular block 416, in cooperation with the first triangular block 417, drives the screening cylinder 411 to rise. When the screening cylinder 411 rises, it stretches the second spring 415. When the second triangular block 416 disengages from the first triangular block 417, the second spring 415 will rebound directly, thereby causing the screening cylinder 411 to fall and generate secondary vibration, thereby further improving the screening efficiency of grains.

[0033] The screened grains will fall onto the guide block 503 through the screen 412, and then into the collection shell 502 through the guide block 503. When it is necessary to remove the grains inside the collection shell 502, the threaded rod 506 can be rotated. The threaded rod 506 will drive the locking block 507 to rise, and the locking block 507 will disengage from the inside of the block 509, thereby releasing the restriction on the block 509, and thus releasing the restriction on the collection shell 502, so that the collection shell 502 can be disassembled, making it easier to remove the collected grains.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
