[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figures 1-4 This utility model provides a lifting machine for washing wheat grains, including a bottom box 1, a roller 2 with brake connected to the bottom of the bottom box 1, an electric push rod 8 fixedly connected to the outer side of the bottom box 1, a push plate 3 slidably connected to the bottom of the inner cavity of the bottom box 1, and the telescopic end of the electric push rod 8 passing through the bottom box 1 and fixedly connected to the push plate 3. In this embodiment, the brake roller 2 is a product of the prior art. The bottom box 1 can be locked by pressing the brake pad on the brake roller 2, so that the elevator can be placed stably. One side of the push plate 3 is provided with a slope, and the slope surface is in direct contact with the washed wheat grains. When the electric push rod 8 is activated, it will extend and push the push plate 3 to move, and the push plate 3 will push the wheat grains to move.

[0018] An inclined component 5 is fixedly connected to the bottom of the inner cavity of the base box 1 on the side away from the push plate 3. The inclined component 5 is driven by a conveying component 4, which is used to lift the washed wheat grains. A docking component 6 is rotatably connected to the top of the conveying component 4. An abutment component 7 is fixedly connected to the outer wall of the base box 1. The conveying component 4 includes a conveyor belt frame 401 that is slidably connected to the inner wall of the base box 1. Two pulleys are provided on the inner side wall of the conveyor belt frame 401. A conveyor belt 402 is driven by the outer arc surface of the two pulleys. The surface of the conveyor belt 402 is evenly distributed. There are several storage plates 403. A motor bracket 404 is fixedly connected to the outer side of the conveyor belt frame 401. A rotary motor 405 is fixedly connected to the motor bracket 404. The output end of the rotary motor 405 passes through the conveyor belt frame 401 and is fixedly connected to the pulley. A sealing element 406 is mated to the bottom of the conveyor belt frame 401. The sealing element 406 is slidably connected to the bottom of the inner cavity of the base box 1. There is a gap between the top of the sealing element 406 and the outer side of the storage plate 403. The top of the storage plate 403 is provided with a groove. The storage plate 403 is made of rubber.

[0019] In this embodiment, the conveying component 4 can lift the washed wheat grains from a low position to a high position. The combination of the rotating motor 405 and the pulley drives the conveyor belt 402 for transmission. The conveyor belt 402 drives several storage plates 403 to rotate cyclically from the bottom to the top. When the storage plate 403 is at the bottom, the washed wheat grains can be scooped up from the bottom box 1 and stored inside the storage plate 403. Then, the conveyor belt 402 carries the washed wheat grains upward. When it reaches the top, the tilting of the storage plate 403 allows the washed wheat grains inside to be poured out.

[0020] In the above scheme, it should be noted that: since there is a gap between the top of the seal 406 and the outer side of the storage plate 403, and the storage plate 403 is made of rubber, the storage plate 403 moving on the surface of the conveyor belt 402 can undergo elastic deformation near the top and bottom of the conveyor belt 402. At the same time, the storage plate 403 can also pass through the gap, thereby facilitating the continuous conveying of the washed wheat grains by the storage plate 403.

[0021] Please see Figures 1-4The tilting component 5 includes a rotating bracket 501 fixedly connected to the bottom of the inner cavity of the base box 1. An electric telescopic rod 502 is rotatably connected to the top of the rotating bracket 501. A rotating connector 503 is fixedly connected to the telescopic end of the electric telescopic rod 502. A connecting rod 504 is rotatably connected to the rotating connector 503. The connecting rod 504 is U-shaped. Torsion spring assemblies 505 are symmetrically fixedly connected to both ends of the connecting rod 504. The torsion spring assemblies 505 are fixedly connected to the outer side of the conveyor belt frame 401. The docking component 6 includes a rotating component 601 rotatably connected to the outer side of the conveyor belt frame 401. A docking component 602 is fixedly connected to the other end of the rotating component 601. An arc-shaped groove is provided on the side of the docking component 602. There is a gap between the arc-shaped groove and the storage plate 403. A locking knob 603 is provided through the rotating component 601. The locking knob 603 is threadedly connected to the outer side of the conveyor belt frame 401. The locking knob 603 contacts and presses against the outer side of the rotating component 601.

[0022] It should be noted that in the above solution: the torsion spring assembly 505 is existing technology. The torsion spring assembly 505 includes a torsion spring box, which is fixedly connected to the outside of the conveyor belt frame 401. A torsion spring is fixedly connected to the inner arc surface of the torsion spring box. The other end of the torsion spring is fixedly connected to the connecting rod 504. The connecting rod 504 is rotatably connected to the outside of the conveyor belt frame 401. The structure of the torsion spring assembly 505 is used to enable the connecting rod 504 to tilt and rotate relative to the conveyor belt frame 401 to a certain extent. During the subsequent linear sliding process of the bottom of the conveyor belt frame 401 driven by the elastic telescopic rod 701, the elastic rotation of the connecting rod 504 can ensure that the internal parts of the hoist will not jam without the electric telescopic rod 502 changing.

[0023] In this embodiment, the tilt angle of the docking component 602 can be adjusted by the rotating component 601 in the docking component 6, and the structure of the locking knob 603 can fix the tilt angle of the docking component 602, ensuring accurate docking of the device. At the same time, the electric telescopic rod 502 with tilt support can provide tilt support for the conveyor belt frame 401, which can adjust the lifting height of the wheat grains.

[0024] Please see Figures 1-4The abutment component 7 includes an elastic telescopic rod 701 fixedly connected to the outer side of the base box 1. A transmission connector 702 is fixedly connected to the elastic telescopic end of the elastic telescopic rod 701. A sealing plate 705 is fixedly connected to the outer arc surface of the transmission connector 702. The sealing plate 705 is slidably connected to the outer side of the base box 1. A through sliding groove 704 is provided on the side of the base box 1 near the elastic telescopic rod 701. The sealing plate 705 covers the outside of the sliding groove 704 and the width of the sealing plate 705 is greater than the width of the sliding groove 704. A sliding member 703 is slidably connected to the inner wall of the sliding groove 704. The side of the sliding member 703 is fixedly connected to the side of the sealing plate 705 away from the transmission connector 702. The other end of the sliding member 703 is rotatably connected to the outer side of the conveyor belt frame 401.

[0025] It should be noted that in the above solution: the elastic telescopic rod 701 is existing technology. The elastic telescopic rod 701 includes a sleeve, a spring is provided inside the sleeve, and a sliding rod is fixedly connected to the other end of the spring. The sliding rod is slidably connected to the inner wall of the sleeve. The elastic telescopic rod 701 can ensure that the bottom feed end of the conveyor belt 402 is always in contact with the washed wheat grains. At the same time, in actual use, when the elastic telescopic rod 701 does not change, existing rubber parts can be used to block the sliding channel 704, which can prevent the wheat grains inside the bottom box 1 from scattering. Alternatively, a receiving box can be placed on the side of the bottom box 1 and below the sliding channel 704 to collect the scattered wheat grains. In this embodiment, the structure of the elastic telescopic rod 701 allows for adaptive adjustment of the bottom end of the conveyor belt 402 during the adjustment of the tilt angle of the conveyor belt 402, further ensuring that the bottom feed end of the conveyor belt 402 is in full contact with the washed wheat grains, thereby further facilitating the transportation of wheat.

[0026] The working principle and usage process of this utility model are as follows: First, the washed wheat grains are poured into the bottom box 1, and then the electric push rod 8 is started to extend. The electric push rod 8 will drive the push plate 3 to move, which can push the wheat grains towards the bottom of the conveyor belt 402 and squeeze the bottom feed end of the conveyor belt 402. At this time, the rotating motor 405 is started, which drives the pulley to rotate, thereby achieving the effect of driving the conveyor belt 402 to transmit power. Next, during the transmission process of the conveyor belt 402, the conveyor belt 402 drives several storage plates 403 to be lifted from the bottom to the top. When the storage plate 403 is at the bottom of the conveyor belt 402, its opening is tilted upwards. The storage plate 403 contacts the washed wheat grains, so that the washed wheat grains can be scooped up and stored inside the storage plate 403. As the conveyor belt 402 is driven and lifted, when the storage plate 403 is driven to the top of the conveyor belt 402, the tilt angle of the storage plate 403 increases, realizing the dumping of the washed wheat grains. Next, when it is necessary to adjust the top height of the conveyor belt 402, the electric telescopic rod 502 is activated first, causing the electric telescopic rod 502 to extend and retract. The electric telescopic rod 502 will drive the connecting rod 504 to move, and the connecting rod 504 will drive the conveyor belt frame 401 to tilt and adjust. In this way, the top height of the conveyor belt 402 will change, thereby realizing the adjustment of the top height of the conveyor belt 402. Finally, as the wheat grain content inside the bottom box 1 decreases, the compressive force on the elastic telescopic rod 701 decreases. Since the rotating bracket 501 and the electric telescopic rod 502 are rotatably connected, and the electric telescopic rod 502 can cooperate to perform telescopic movement, the elastic telescopic rod 701 drives the bottom of the conveyor belt 402 to move closer to the push plate 3. When the bottom of the conveyor belt 402 is blocked by the accumulation of wheat grains again, the elastic telescopic rod 701 stops extending outward elastically. This ensures that the bottom feed end of the conveyor belt 402 is always in contact with the accumulated wheat grains, ensuring the stability of the cleaned wheat grains during the lifting process. When the height of the remaining wheat raw material is lower than the height of the push plate 3, the electric push rod 8 pushes the push plate 3 to slide, thereby pushing the cleaned wheat grain raw material towards the bottom feed end of the conveyor belt 402, thereby reducing the residue of cleaned wheat grains at the bottom of the inner cavity of the bottom box 1.
