Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain processing, specifically a grain lifting device for grain processing. Background Technology
[0002] Grains are an important type of crop, serving as one of the main energy sources in the human diet. Grains generally refer to herbaceous plants whose seeds or fruits are edible, and they are widely cultivated around the world. Grain processing is an industry that involves transforming grain raw materials into food and other products through a series of processes. Before grains can be processed, they need to be lifted for feeding.
[0003] However, most traditional lifting devices rely on manual labor to bag the grain and transport it to the processing equipment at a higher level. This process is time-consuming, labor-intensive, and poses certain safety hazards. Some conveyors use double doors to load and unload the grain, but this method requires manual closing or opening, and the gap between the two doors can easily cause some grain to leak out, affecting the efficiency of grain lifting. Therefore, a grain lifting device for grain processing is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a grain lifting device for grain processing. It features the ability to lift grain to a high height and rotate and flip the grain loading frame for easy grain feeding. This solves the problem that traditional lifting devices mostly rely on manual bagging of grain and transporting it to higher processing equipment, a time-consuming and labor-intensive process with potential safety hazards. Some conveyors use double-door panels for loading and unloading grain, but this method requires manual opening and closing, and the gap between the two doors can easily allow some grain to leak out, affecting the efficiency of grain lifting.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0027] In the embodiments, by Figure 1-4The present invention discloses a grain lifting device for grain processing. The present invention includes a base 1, casters 2 at the bottom of the base 1, and four support feet 3 symmetrically distributed in pairs at the bottom of the base 1. Each of the four support feet 3 has a mounting hole inside. A support frame 4 is fixedly connected to the top of the base 1. A lifting device 5 is installed inside the support frame 4. A connecting frame 6 is fixedly connected to the outside of the lifting device 5 and slidably connected to the support frame 4. A protective box 7 is fixedly connected to the outside of the connecting frame 6. A rotating device 8 is installed inside the protective box 7. A fixed shaft 9 is fixedly connected inside the rotating device 8, penetrating and extending into the connecting frame 6. A receiving frame 10 is fixedly connected to the outside of the fixed shaft 9 and rotatably connected to the inside of the connecting frame 6.
[0028] The base 1 has four threaded rods 11 that are symmetrically distributed in pairs on the left and right sides. The bottom of the four threaded rods 11 is rotatably connected to the top of the four support feet 3. The top of each of the four threaded rods 11 is fixedly connected to a knob 12.
[0029] In this embodiment, during actual use, when the knob 12 is turned, the first threaded rod 11 will rotate, thereby causing the support foot 3 under the base 1 to move. After the support foot 3 moves to the ground, the position of the base 1 can be fixed by fasteners such as screws and bolts passing through the mounting holes. When the support foot 3 is raised, the base 1 can be moved by the casters 2.
[0030] The lifting device 5 includes a first motor 51 fixedly connected to the outside of the support frame 4. The output shaft of the first motor 51 is fixedly connected to a second threaded rod 52 rotatably connected to the inside of the support frame 4. The outside of the second threaded rod 52 is connected to a transmission block 53 fixedly connected to the connecting frame 6 via a threaded transmission.
[0031] In this embodiment, during actual use, the start of the first motor 51 will drive the second threaded rod 52 to rotate, thereby causing the transmission block 53 outside the second threaded rod 52 to move in the direction of the second threaded rod 52, and driving the connecting frame 6 outside it to move.
[0032] The support frame 4 has two sliding grooves inside, and the front and rear sides of the connecting frame 6 are fixedly connected with limiting frames 13 that are slidably connected to the two sliding grooves respectively.
[0033] In this embodiment, during actual use, when the connecting frame 6 moves, it will drive the limiting frame 13 in front and behind it to move up and down. The limiting frame 13 stabilizes the moving direction of the connecting frame 6 by sliding with the slide groove, and provides auxiliary support for the movement of the connecting frame 6.
[0034] The rotating device 8 includes a second motor 81 fixedly connected to the outside of the protective box 7. The output shaft of the second motor 81 is fixedly connected to a worm gear 82 rotatably connected to the inside of the protective box 7. The inside of the protective box 7 is rotatably connected to a worm wheel 83 that meshes with the worm gear 82. The inside of the worm wheel 83 is fixedly connected to the outside of the fixed shaft 9.
[0035] In this embodiment, during actual use, the start of the second motor 81 will drive the worm gear 82 to rotate, and drive the worm wheel 83 meshing with it in the protective box 7 to rotate, thereby driving the receiving frame 10 inside the connecting frame 6 to rotate. Since the receiving frame 10 is heavy after being loaded with grain, the cooperation between the worm wheel 83 and the worm gear 82 can prevent the receiving frame 10 from rotating naturally under the action of gravity. The worm wheel 83 cannot drive the worm gear 82 to rotate.
[0036] The connecting frame 6 is arranged in an L-shape facing downwards, and the base 1 has a clearance groove located below the receiving frame 10 inside.
[0037] In this embodiment, during actual use, when the receiving frame 10 is lowered, when the connecting frame 6 descends to the bottom of the support frame 4, the bottom surface of the receiving frame 10 is below the ground of the base 1, leaving space for the receiving frame 10 to descend, which facilitates the collection and loading of grains by the receiving frame 10.
[0038] Working principle:
[0039] When lifting the grain, the device is first stabilized by turning the knob 12 and fixing the support foot 3. Then, the receiving frame 10 is lowered by the first motor 51. After the grain is loaded into the receiving frame 10, the receiving frame 10 can be raised by the lifting device 5. After the receiving frame 10 reaches the appropriate position, the second motor 81 can be started to rotate the receiving frame 10, and then the grain in the receiving frame 10 is poured out at a certain height. The poured grain enters the next process for processing.
