Description

Technical Field

[0001] The present invention relates to the technical field of elevators, in particular to a grain elevator based on modern agricultural machinery and equipment. Background Art

[0002] Grain elevator is a kind of vertical conveying equipment widely used in grain processing, warehousing, transportation and other scenarios. In grain processing plants or grain storage places, a grain elevator is often used to drive the hopper movement through the mechanical transmission of the conveyor belt to lift the bulk or granular grain in a vertical or inclined direction to achieve material transportation with height differences. It is mainly used to lift grain (such as wheat, corn, rice, beans, etc.) from low to high to meet subsequent processing, storage or transportation needs.

[0003] Traditional elevators typically use a conveyor belt to drive a hopper that lifts grain from a low location to a high location. Finally, a discharge hopper at the top of the elevator precisely drops the grain into a storage tank or silo. Because the discharge hopper is often bolted directly to the elevator, operators are required to shut down the machine and adjust the overall direction of the elevator when transferring grain to a different storage tank. This cumbersome operation results in low snack transportation efficiency and is inconvenient to operate.

[0004] During the operation of the elevator, when the position of the elevator discharge port needs to be adjusted or the equipment fails or temporary maintenance is required, some grain will still be transported on the elevator lifting plate or discharge port after the power is turned off. As a result, during transportation or maintenance, it is easy for the grain to flow through the discharge port to the ground, causing grain waste and inconvenience in subsequent cleaning;

[0005] When grain needs to be added to the elevator, the operator usually lifts the bag of grain into the upper hopper and lifts it up by hand. However, since the bag of grain is usually large, it is not convenient for the operator to grab it. Moreover, if all the grain in the bag is poured into the upper hopper at one time, it is easy to cause the grain to accumulate too thickly at the feed port of the elevator, thereby causing the feed channel to be blocked, which is not practical.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] like Figure 1 、 Figure 2 、 Figure 6-Figure 8 As shown, the present invention discloses a grain elevator based on modern agricultural machinery, comprising a base 1, a lifting structure 2 mounted on the base 1, a feeding structure 4 provided on the lifting structure 2, a rotating structure 5 connected to the lifting structure 2, and an opening and closing structure 6 coordinated with the rotating structure 5; the rotating structure 5 comprises a discharge hopper 501 and a connecting pipe 502 fixedly connected to the discharge hopper 501, the lifting structure 2 is provided with a discharge hopper 501, when the grain falling onto the conveyor belt 204 is pushed to the top of the frame 201 by the lifting plate 205, the grain is then The grain flows to the inside of the discharge hopper 501 under the action of gravity, so that the grain can be transported to the granary or storage tank through the discharge pipe 503. When the grain needs to be transported to the grain storage tank in different directions, it is only necessary to adjust the direction of the discharge pipe 503. The bottom of the connecting pipe 502 is rotatably connected to the discharge pipe 503, and the discharge pipe 503 is fixedly connected to the gear ring 504. The outer wall of the discharge hopper 501 is fixedly connected to the mounting plate 505, and the mounting plate 505 is fixedly connected to the second motor 506. The output shaft of the second motor 506 is fixedly connected to the second motor 506. A gear 507, the first gear 507 and the ring gear 504 are meshed with each other; to avoid the change of the overall direction of the elevator, when the sealing cover 602 is turned 90 degrees and closed, the bottom of the limit bar 604 will slide out of the limit groove 609 provided on the limit ring 608, and at this time the limit bar 604 will no longer block the rotation of the discharge pipe 503, and then the second motor 506 installed on the outer wall of the discharge hopper 501 through the mounting plate 505 drives the first gear 507 to rotate, and the first gear 507 drives the ring gear 504 to rotate, and the ring gear 504 drives the discharge pipe 503 to rotate. The end of the connecting pipe 502 rotates until the discharge pipe 503 is rotated to a specified angle, and then the telescopic section of the hydraulic rod 607 contracts, driving the central shaft 601 to rotate in the opposite direction, and the central shaft 601 drives the sealing cover 602 to rotate in the opposite direction by 90 degrees. At this time, the sealing cover 602 is in an open state, which facilitates the flow of grain through the connecting pipe 502 into the grain storage tank. At the same time, during the downward movement of the limit bar 604, the bottom is engaged with the limit groove 609 at the corresponding position, thereby limiting the position of the discharge pipe 503 and avoiding the discharge pipe 503 from rotating under the action of external force, with strong stability.

[0036] Specifically, such as Figure 2 and Figure 7-Figure 8As shown, the opening and closing structure 6 includes a central axis 601 and a sealing cover 602 fixedly connected to the central axis 601, the central axis 601 is rotatably connected to the connecting tube 502, and the end of the central axis 601 is fixedly connected to the second gear 606, and the hydraulic rod 607 installed inside the mounting frame 603 drives the limit bar 604 to slide upward, and the limit bar 604 drives the rack 605 to move upward, and the rack 605 drives the second gear 606 to rotate, and the second gear 606 drives the central axis 601 to rotate on the connecting tube 502 until the central axis 601 drives the sealing cover 602 to flip 90 degrees. The outer wall of the connecting tube 502 is fixedly connected to the mounting frame 603, and the mounting frame 603 is fixedly connected to the cover plate 610. The mounting frame 603 is slidably connected to the limit bar 604, and the limit bar 604 is an "L"-shaped structure. A rack 605 is fixedly connected, and the rack 605 and the second gear 606 are meshed with each other. A hydraulic rod 607 is fixedly connected to the inside of the mounting frame 603, and the telescopic end of the hydraulic rod 607 is fixedly connected to the limit bar 604. A limit ring 608 is fixedly connected to the discharge pipe 503, and the limit ring 608 is an arc-shaped structure. A plurality of limit grooves 609 are provided on the limit ring 608. The bottom of the limit bar 604 and the limit groove 609 are engaged with each other. At this time, the discharge port of the connecting pipe 502 is in a closed state, avoiding the problem of residual grain inside flowing to the ground during the adjustment of the direction of the connecting pipe 502, and the setting of the sealing cover 602 facilitates the flexible control of the opening and closing of the discharge hopper 501, which can not only flexibly adjust the valve opening according to production needs and accurately control the discharge flow of materials such as grain, but also quickly cut off the discharge, with strong flexibility.

[0037] Specifically, such as Figures 1-6 As shown, the lifting structure 2 includes a frame 201 and two first rotating shafts 202 rotatably connected to the ends of the frame 201. The frame 201 is fixedly connected to the base 1, and the two first rotating shafts 202 are fixedly connected to drive rollers 203. A conveyor belt 204 is wound between the two drive rollers 203. The two drive rollers 203 drive and drive the conveyor belt 204 to move. A plurality of lifting plates 205 are fixedly connected to the conveyor belt 204, and the plurality of lifting plates 205 are equidistantly arranged. A protective cover 206 is fixedly connected to the frame 201. The arrangement of the protective cover 206 on the frame 201 improves the aesthetics. At this time, the lifting plates 205 installed on the surface of the conveyor belt 204 drive the grain that falls into the joint between the upper hopper 401 and the frame 201 to rise, thereby realizing the lifting of grain from a low place to a high place to meet the subsequent processing, storage or transportation needs.

[0038] Specifically, such as Figure 1 and Figure 3-Figure 6As shown, the frame 201 is equipped with a driving structure 3, which includes a mounting frame 301 and a first motor 302 fixedly connected to the mounting frame 301. The mounting frame 301 is fixedly connected to the base 1, and a sprocket 303 is fixedly connected to the output shaft of the first motor 302. Another sprocket 303 is fixedly connected to the first rotating shaft 202 at the bottom of the frame 201, and a chain 304 is wound between the two sprockets 303. A protective cover 305 is fixedly connected to the base 1, and the chain The protective cover 305 on the outside of the strip 304 plays a protective role and improves safety. The end of the protective cover 305 is fixedly connected to the mounting frame 301, and then the power supply of the first motor 302 on the mounting frame 301 is connected. The output shaft of the first motor 302 drives the sprocket 303 to rotate, and the sprocket 303 here drives another sprocket 303 on the first rotating shaft 202 to rotate through the chain 304. At this time, the first rotating shaft 202 drives the transmission roller 203 to rotate on the frame 201, which is convenient for the subsequent operation of the elevator and has high operating efficiency.

[0039] Specifically, such as Figure 1 、 Figure 3-Figure 6 and Figure 9As shown, the feeding structure 4 includes a feeding hopper 401 and three guide columns 402 fixedly connected to the interior of the feeding hopper 401, the feeding hopper 401 is fixedly connected to the frame 201, the bottom of the feeding hopper 401 is fixedly connected to the base 1, and a screen 403 is slidably connected between the three guide columns 402. The bag filled with grain is lifted onto the screen 403, and the bag is slowly dragged out with the bag opening facing downward until all the grain in the bag is poured onto the screen 403. During this process, part of the grain will fall into the feeding hopper 401 along the sieve holes on the screen 403, and four springs 404 are fixedly connected between the bottom surface of the screen 403 and the inner wall of the feeding hopper 401. The movable rod 409, the top part of the driving rod 409 and the guide column 402 are both in a "T" shape. The top part of the driving rod 409 conflicts with the top surface of the screen 403. The bottom of the frame 201 is fixedly connected with a mounting cover 405. The top of the mounting cover 405 is rotatably connected to a second rotating shaft 406. A rotating block 407 is fixedly connected to the second rotating shaft 406. A connecting rod 408 is rotatably connected to the rotating block 407. The end of the connecting rod 408 is rotatably connected to the bottom of the driving rod 409. A second pulley 411 is fixedly connected to the second rotating shaft 406, wherein the first pulley is fixedly connected to the first rotating shaft 202 at the bottom of the frame 201. 410, the radius of the first pulley 410 is greater than the radius of the second pulley 411, and a belt 412 is wound between the first pulley 410 and the second pulley 411. When the first motor 302 is running, the first rotating shaft 202 at the bottom of the frame 201 synchronously drives the first pulley 410 at the end to rotate, and the first pulley 410 drives the second pulley 411 to rotate through the belt 412, and then the second pulley 411 drives the second rotating shaft 406 to rotate on the mounting cover 405, and at the same time, the second rotating shaft 406 drives the rotating block 407 at one end of the inner side to rotate. Since the rotating block 407 and the bottom of the driving rod 409 are all rotatably connected with the connecting rod 408, the rotating block 407 During the rotation, the connecting rod 408 drives the driving rod 409 to slide up and down repeatedly along the inner wall of the upper hopper 401. During the rising process of the driving rod 409, the screen 403 moves up under the elastic force of the spring 404, and when the driving rod 409 slides down, its end contacts the upper surface of the screen 403, thereby driving the screen 403 to move down. At this time, the screen 403 repeatedly swings up and down along the guide column 402, which makes it easier for the food accumulated on the screen 403 to fall into the upper hopper 401 through the sieve holes, which not only makes the food distribution more even, but also avoids the problem of too much food being added at one time, which causes the food to accumulate too thickly at the feed port of the elevator, thereby causing the feed channel to be blocked, affecting the normal entry of materials into the elevator.

[0040] When the present invention is in use, the bag filled with grain is lifted onto the screen 403, and the bag is slowly dragged outward with the bag opening facing downward until all the grain in the bag is poured onto the screen 403. During this process, some grain will fall into the upper hopper 401 along the sieve holes on the screen 403. Then, the power supply of the first motor 302 on the mounting frame 301 is connected, and the output shaft of the first motor 302 drives the sprocket 303 to rotate. The sprocket 303 here drives another sprocket 303 on the first rotating shaft 202 to rotate through the chain 304. At this time, the first rotating shaft 202 drives the transmission roller 203 to rotate on the frame 201, which is convenient for the subsequent operation of the elevator. , the operation efficiency is high, because the other end of the frame 201 on the base 1 is equipped with the same transmission roller 203 through another first rotating shaft 202, and then the two transmission rollers 203 drive the conveyor belt 204 to move, and at this time, the lifting plate 205 installed on the surface of the conveyor belt 204 drives the grain that falls into the joint between the upper hopper 401 and the frame 201 to rise, thereby realizing the lifting of the grain from a low place to a high place to meet the subsequent processing, storage or transportation needs, and the setting of the protective cover 206 on the frame 201 improves the aesthetics, and the protective cover 305 on the outside of the chain 304 plays a protective role, thereby improving safety;

[0041] While the first motor 302 is running, the first rotating shaft 202 located at the bottom of the frame 201 synchronously drives the first pulley 410 at the end to rotate, and the first pulley 410 drives the second pulley 411 to rotate through the belt 412, and then the second pulley 411 drives the second rotating shaft 406 to rotate on the mounting cover 405, and at the same time, the second rotating shaft 406 drives the rotating block 407 at one end of the inner side to rotate. Since the rotating block 407 and the bottom of the driving rod 409 are all rotatably connected with the connecting rod 408, during the rotation of the rotating block 407, the connecting rod 408 drives the driving rod 409 along the inner wall of the upper hopper 401. The screen 403 is repeatedly slid up and down. During the rising process of the driving rod 409, the screen 403 moves up under the elastic force of the spring 404. When the driving rod 409 slides down, its end portion contacts the upper surface of the screen 403, thereby driving the screen 403 to move down. At this time, the screen 403 repeatedly shakes up and down along the guide column 402, making it easier for the grain accumulated on the screen 403 to fall into the upper hopper 401 through the sieve holes. This not only makes the grain distribution more even, but also avoids the problem of excessive accumulation of grain at the elevator feed port due to adding too much grain at one time, thereby causing the feed channel to be blocked, affecting the normal entry of the material into the elevator.

[0042] When the grain falling on the conveyor belt 204 is pushed to the top of the frame 201 by the lifting plate 205, the grain flows into the inside of the discharge hopper 501 under the action of gravity, so that the grain can be transported to the granary or storage tank through the discharge pipe 503. When it is necessary to transport the grain to the storage tank in a different direction, it is only necessary to adjust the direction of the discharge pipe 503 to avoid the change of the overall direction of the elevator. First, the hydraulic rod 607 installed in the installation frame 603 drives the limit bar 604 to slide upward, and the limit bar 604 drives the rack 605 to move upward. The rack 605 drives the second gear 606 to rotate, and the second gear 606 drives the central shaft 601 to rotate on the connecting pipe 502 until the central shaft 601 drives the sealing cover 602 to turn 90 degrees. At this time, the discharge port of the connecting pipe 502 is in a closed state, avoiding the problem of residual grain inside flowing to the ground during the adjustment of the direction of the connecting pipe 502. The setting of the sealing cover 602 is convenient for flexible control of the opening and closing of the discharge hopper 501, which can not only flexibly adjust the valve opening according to production needs, accurately control the discharge flow of materials such as grain, but also quickly cut off The discharge is flexible. When the sealing cover 602 is turned 90 degrees and closed, the bottom of the limit bar 604 will slide out of the limit groove 609 provided on the limit ring 608. At this time, the limit bar 604 will no longer block the rotation of the discharge pipe 503. Then, the second motor 506 installed on the outer wall of the discharge hopper 501 through the mounting plate 505 drives the first gear 507 to rotate. The first gear 507 drives the ring gear 504 to rotate. The ring gear 504 drives the discharge pipe 503 to rotate at the end of the connecting pipe 502 until the discharge pipe 503 is rotated to a specified angle. Then the telescopic section of the hydraulic rod 607 contracts, driving the central shaft 601 to rotate in the opposite direction, and the central shaft 601 drives the sealing cover 602 to rotate in the opposite direction by 90 degrees. At this time, the sealing cover 602 is in an open state, which is convenient for the grain to pass through the connecting pipe 502 and flow into the grain storage tank. At the same time, during the downward movement of the limit bar 604, the bottom and the limit groove 609 at the corresponding position are engaged, thereby limiting the position of the discharge pipe 503 and avoiding the discharge pipe 503 from rotating under the action of external force. It has strong stability, and the setting of the cover plate 610 facilitates the inspection and maintenance of the internal parts of the installation frame 603.
