Description

Technical Field

[0001] This utility model belongs to the field of grain machinery technology, and specifically relates to a high-speed bulk material spreading device. Background Technology

[0002] Grain warehouses are the most important grain storage facilities. During the processes of grain transfer, leveling, and clearing, the structural characteristics and operational content of grain warehouses, which are large in volume and height and are enclosed environments, pose unique technical challenges because grain is in bulk.

[0003] Existing manual operations suffer from problems such as long processing times, harsh working conditions, low efficiency, high labor intensity, and significant health and safety concerns, facing multiple technical bottlenecks: In terms of efficiency, workers must perform heavy shoveling, leveling, or cleaning operations within confined spaces, which is extremely time-consuming and discontinuous; in terms of working conditions, the dust concentration inside the silo is extremely high (potentially causing explosions and respiratory illnesses), there is a risk of oxygen deficiency, insufficient lighting, and the hazard of falls from heights or suffocation from being trapped in fluidized grain piles; in terms of intensity, continuous heavy physical labor far exceeds the limits of human endurance. Therefore, the leveling, cleaning, and transfer of grain in silos urgently require mechanization and automation to effectively improve operational efficiency and reduce labor intensity. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a high-speed bulk material throwing device. By controlling the speed and rotation angle of the belt conveyor rollers, material can be thrown at different distances and positions. The high-speed conveying of the front and rear rollers generates centrifugal force, which throws the bulk grain particles to designated positions or the next process, realizing the transfer of grain during clearing or leveling operations, improving production efficiency and reducing costs.

[0005] The technical solution of this utility model is as follows: a high-speed bulk material spreading device, including a belt conveyor, a hopper, a rotary support, an upper frame, a lower frame, a drive motor, a rotary drive, and a housing. The belt conveyor includes a front roller and a rear roller, which are respectively mounted on the upper ends of the upper frame through bearing seats. A belt is sleeved between the front roller and the rear roller. The drive motor is located at the lower part of the upper frame. The output end of the drive motor is connected to the rotating shaft of the rear roller through a drive belt. The hopper is located above the upper frame, and the discharge port of the hopper is located above the belt. One end of the rotary drive is fixedly mounted on the lower frame, and the other end is rotatably connected to the rotary support. The upper frame is located on the upper part of the rotary support.

[0006] The belt is also equipped with a tension roller above the discharge port of the hopper. The tension roller is connected to a tension adjuster, which is fixedly connected to the upper frame.

[0007] The tension roller has its two ends pressed against the belt, and the diameter of the middle part of the tension roller is smaller than the diameter of its two ends.

[0008] The upper frame is equipped with casters around its bottom.

[0009] The rotary drive includes a drive gear pair and a rotary bearing, and is used to drive the rotary support to rotate.

[0010] The technical advantages of this utility model are as follows: 1. The belt conveyor of this utility model operates under the drive of a drive motor. By adjusting the speed of the motor, the throwing distance can be adjusted to achieve material throwing at different distances; 2. The slewing support of this utility model rotates under the drive of a slewing drive, and the throwing angle can be adjusted to achieve material throwing at different positions.

The belt conveyor 1 includes a front roller 8 and a rear roller 13, which are respectively mounted on the upper ends of the upper frame 4 via bearing seats. A belt 11 is sleeved between the front roller 8 and the rear roller 13. The drive motor 6 is located at the lower part of the upper frame 4, and the output end of the drive motor 6 is connected to the rotating shaft of the rear roller 13 via a drive belt. The hopper 2 is located above the upper frame 4, and the discharge port of the hopper 2 is located above the belt 11. One end of the rotary drive 7 is fixedly mounted on the lower frame 5, and the other end is rotatably connected to the rotary support 3. The upper frame 4 is located on the upper part of the rotary support 3.

[0015] In actual use, when this invention is working, the drive motor 6 drives the front roller 8 and the rear roller 13 to rotate at high speed. Grain enters the grain bin 2 from the previous process, and the material is distributed on the belt 11. The belt 11 rotates at high speed, and the grain material is scattered to the designated position under the action of high-speed centrifugal force. The belt conveyor 1 operates under the drive motor 6. By adjusting the speed of the motor 6, the scattering distance is adjusted. The slewing support 3 rotates under the drive of the slewing drive 7, adjusting the scattering angle to achieve material scattering at different distances and positions. This invention can achieve material scattering at different distances and positions by controlling the speed and rotation angle of the belt conveyor rollers. The high-speed conveying of the front and rear rollers generates centrifugal force, scattering the loose grain particles to the designated position or the next process, realizing grain transfer in clearing or leveling operations, improving production efficiency and reducing costs.
