Description

Technical Field

[0001] This utility model relates to the field of feed production technology, and specifically discloses a material lifting device for feed production. Background Technology

[0002] In feed production and processing, it is often necessary to lift powdery, granular, or fragmented materials from lower levels to higher levels, such as cement silos, mixers, or packaging equipment. Currently, the most widely used vertical lifting equipment is the bucket elevator, which uses buckets to carry materials to the top and then throws them out to achieve conveying.

[0003] However, bucket elevators have some obvious drawbacks in practical applications: First, their lifting height is usually fixed, and once installed, the height of the discharge port is difficult to adjust flexibly, failing to adapt to the feeding needs of equipment at different heights, resulting in poor flexibility. Second, during operation, material residue and dust are easily generated when the buckets are thrown out, causing not only material waste but also affecting the cleanliness of the working environment. Therefore, a material lifting device for feed production is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a material lifting device for feed production. Through a multi-stage spiral lifting and linkage lifting structure, it realizes continuous material lifting and flexible height adjustment, and has the advantages of sealing and preventing leakage, stable operation and convenient movement.

[0005] This utility model is implemented as follows: a material lifting device for feed production includes a support frame, inside which are arranged three lifting components with the same structure. Each lifting component includes a movable frame, the inner wall of which is fixedly connected to a cylinder, the inner wall of which is rotatably connected to a rotating shaft, the outer wall of which is fixedly connected to a spiral blade, and a drive motor with its output end extending into the cylinder and fixedly connected to the rotating shaft is installed on the upper end face of the movable frame. The outer wall of the cylinder is provided with a discharge port and a feed port distributed vertically on both sides.

[0006] The bracket has three evenly distributed sliding grooves extending through its front and rear end faces. A threaded rod is rotatably connected to the inner wall of the middle front sliding groove, while limit rods are fixedly connected to the inner walls of the other sliding grooves. A servo motor with its output end fixedly connected to the threaded rod is mounted on the upper end face of the bracket. Slider blocks that slide in the sliding grooves are fixedly connected to the front and rear end faces of the three movable frames. The middle front slider is threadedly connected to the threaded rod, while the other sliders are slidably connected to the limit rods. Spur racks are fixedly connected to the outer walls of the two side sliders, and gears are rotatably connected to the outer wall of the middle slider via a coupling. Both spur racks are meshed with the gears.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Please see Figure 1-3 A material lifting device for feed production includes a support 1. The support 1 has three identical lifting components inside. Each lifting component includes a movable frame 2. A cylinder 3 is fixedly connected to the inner wall of the movable frame 2. A rotating shaft 6 is rotatably connected inside the cylinder 3. A spiral blade 7 is fixedly connected to the outer wall of the rotating shaft 6. A drive motor 8 with its output end extending into the cylinder 3 and fixedly connected to the rotating shaft 6 is installed on the upper end face of the movable frame 2. A discharge port 5 and a feed port 4 are respectively provided on both sides of the outer wall of the cylinder 3.

[0022] The front and rear ends of the bracket 1 are each provided with three evenly distributed sliding grooves 10. The inner wall of the middle sliding groove 10 on the front side is rotatably connected to a threaded rod 11. The inner walls of the other sliding grooves 10 are fixedly connected to limit rods 13. The upper end of the bracket 1 is equipped with a servo motor 12 whose output end is fixedly connected to the threaded rod 11. The front and rear ends of the three movable frames 2 are each fixedly connected to sliders 14 that are slidably connected to the sliding grooves 10. The middle slider 14 on the front side is threadedly connected to the threaded rod 11. The other sliders 14 are slidably connected to the limit rods 13. The outer walls of the sliders 14 on both sides are fixedly connected to racks 15. The outer wall of the middle slider 14 is rotatably connected to a gear 16 via a coupling. The two racks 15 are meshed with the gear 16.

[0023] In this embodiment: the drive motor 8 is started, which drives the rotating shaft 6 to rotate, thereby driving the spiral blades 7 to rotate, conveying the feed at the bottom of the cylinder 3 upward and discharging it from the discharge port 5. The feed then enters the feed inlet 4 of the next cylinder 3 through the telescopic hose 9 and continues to be lifted upward. The feed is continuously lifted by three lifting components. The servo motor 12 is started, which drives the threaded rod 11 to rotate, thereby driving the middle movable frame 2 and cylinder 3 to move upward or downward through the slider 14. At the same time, the middle slider 14 drives the gear 16 to roll upward or downward along the left straight rack 15, thereby driving the right movable frame 2 and cylinder 3 to move upward or downward synchronously through the right straight rack 15. This adjusts the height of the right discharge port 5, allowing the feed lifting height to be adjusted as needed, making it highly practical.

[0024] As a technical optimization of this utility model, the feed inlet 4 and the discharge outlet 5 on adjacent sides are connected by a telescopic hose 9.

[0025] In this embodiment, feed spillage is prevented by connecting the feed inlet 4 and the discharge outlet 5 on adjacent sides with a telescopic hose 9.

[0026] As a technical optimization of this utility model, the movable frame 2 on the left side is fixedly connected to the inner wall of the bracket 1.

[0027] In this embodiment: by fixing the left movable frame 2 to the inner wall of the bracket 1, it is prevented that when the middle movable frame 2 is raised or lowered, the left movable frame 2 will be raised or lowered synchronously.

[0028] As a technical optimization of this utility model, universal brake wheels are provided at the four corners of the lower end face of the bracket 1.

[0029] In this embodiment, universal brake wheels are provided at the four corners of the lower end face of the bracket 1 to facilitate the movement of equipment.

[0030] As a technical optimization of this utility model, the servo motor 12 is configured as a worm gear reducer motor.

[0031] In this embodiment, by setting the servo motor 12 as a worm gear reducer motor, it is convenient to rotate and fix the threaded rod 11, and to prevent the threaded rod 11 from rotating accidentally.

[0032] As a technical optimization of this utility model, a controller is provided on the outer wall of the bracket 1, and the drive motor 8 and the servo motor 12 are both electrically connected to the controller.

[0033] In this embodiment, the controller facilitates the normal operation of the drive motor 8 and the servo motor 12.

[0034] The working principle and usage process of this utility model are as follows: In use, feed is fed into the feed inlet 4 of the left cylinder 3. Multiple drive motors 8 are started, driving the rotating shaft 6 to rotate, which in turn drives the spiral blades 7 to rotate, conveying the feed from the bottom of the cylinder 3 upwards and discharging it from the discharge port 5. The feed then enters the feed inlet 4 of the next cylinder 3 through the telescopic hose 9, continuing to rise. The feed is continuously lifted by three lifting components and finally discharged from the discharge port 5 of the right cylinder 3. When adjusting the discharge height, the servo motor 12 is started, driving the threaded rod 11 to rotate. This, in turn, drives the middle movable frame 2 and cylinder 3 to move upwards or downwards via the slider 14. Simultaneously, the middle slider 14 drives the gear 16 to roll upwards or downwards along the left straight rack 15, which in turn drives the right movable frame 2 and cylinder 3 to move upwards or downwards synchronously via the right straight rack 15, thereby adjusting the height of the right discharge port 5. The feed lifting height can be adjusted as needed, making it highly practical.
