[0001] This utility model relates to an auxiliary material dispersing device for underground hoppers to prevent material accumulation and blockage. Background Technology

[0002] When loading and unloading materials such as coal, crushed ore, and non-ferrous metal sand and gravel, tippers are used to unload materials into underground hoppers. When there are many vehicles being unloaded and continuous and rapid unloading is required, the material in the hopper will compress or slow down the conveyor belt, which can easily cause material accumulation and blockage. The conveyor belt may stop while the drive drum continues to rotate, resulting in wear or breakage of the conveyor belt. Utility Model Content

[0011] 1. This utility model, by setting up a propulsion and walking device, can be activated to move forward when materials need to be loosened, so that the spiral loosening device is gradually inserted into the hopper. When unloading begins, the material enters the material head and is agitated by the spiral blades, which facilitates the conveyor belt to transport the material, thereby enabling rapid unloading of materials, reducing costs and improving economy.

[0017] Reference Figures 1-4 An underground hopper auxiliary material dispersing device for preventing material accumulation and blockage includes: a hopper 11, a support 2 fixed on the side of the hopper, a propulsion and walking device placed on the support, and a spiral loosening device fixed on the propulsion and walking device.

[0018] By setting up a propulsion and walking device, the device can be activated to move forward when materials need to be loosened, so that the spiral loosening device is gradually inserted into the hopper 11. When unloading begins, the material enters the material head and is agitated by the spiral blades, which facilitates the conveyor belt to transport the material, thereby enabling rapid unloading of materials, reducing costs and improving economic efficiency.

[0019] The propulsion and walking device includes a frame 3, on which a drive reduction motor 13 is fixed. The output shaft of the drive reduction motor is fixed to a drive gear 14. A sleeper 20 is fixed on the bracket. The drive gear meshes with the side rack 15 of the sleeper.

[0020] The bottom of the frame is connected to a travel gear 4, which meshes with the upper rack 1.

[0021] The walking principle of the propulsion and walking device: By starting the drive reduction motor, the drive reduction motor drives the drive gear to rotate. The drive gear meshes with the side rack on the sleeper, which drives the entire device to move.

[0022] The spiral loosening device includes a loosening reduction motor 5, the output shaft of which is connected to the stirring rod 10 via a coupling, a spiral blade 16 is fixed on the stirring rod, and a cone head 19 is fixed at the end of the stirring rod.

[0023] A baffle is fixed on the frame, and a bushing is fixed on the baffle. The bushing is connected to the agitator through a bearing.

[0024] The top of the bracket is fixed with two parallel sleepers, and each sleeper is fixed with an upper rack 1. The bottom of the frame is connected with a traveling gear 4, which meshes with the upper rack.

[0025] The hopper described above has a sleeve 9 on its side, and the stirring rod is inserted into the sleeve.

[0026] The bracket has two bases 8 fixed on it. One base is fixed with a front limit sensor 7 and the other base is fixed with a rear limit sensor 12.

[0027] Working principle: During use, the drive reduction motor is started, which drives the drive gear to rotate. The drive gear meshes with the side rack on the sleeper, causing the entire device to move. After moving, the stirring rod gradually inserts into the sleeve. When the device moves to the limit stop and contacts the front limit sensor, it stops. At this time, the loosening reduction motor is started, which drives the stirring rod to rotate. When unloading begins, the material enters the material head and is agitated by the spiral blades, which facilitates the conveyor belt to transport the material. This allows for rapid unloading of materials, reduces costs, and improves economic efficiency.

[0028] Both the front and rear limit sensors are microswitches. Their normally closed contacts are connected to the secondary circuit that drives the geared motor to start. They serve as a switch signal to stop the geared motor. The working principle is that when the microswitch contacts the limit stop, its normally closed contact will open, thus disconnecting the geared motor drive circuit and stopping the geared motor. The front and rear limit switches are commonly used in the market as limits for the running position of equipment. Their specific structure and working method have not been improved. This application simply applies them here as limits for the movement of the propulsion and walking device. When the propulsion and walking device moves forward to the limit stop and contacts the front limit sensor, the normally closed contact of the front limit sensor switch opens, causing the geared motor to stop. The propulsion and walking device does not move, indicating that the movement is in place.

[0029] When material loosening is not required, start the drive gear motor to reverse it, and the propulsion walking device will then retract. When the movement reaches the limit stop and the limit sensor contacts the normally closed point of the limit sensor, the drive gear motor will stop, and the propulsion walking device will stop moving, indicating that the retraction is complete.

[0030] The end of the stirring rod is equipped with a cone. After the propulsion and walking device retracts, the cone is placed inside the sleeve. At this time, the cone can block the sleeve and prevent material leakage.

[0031] The baffle is fixed to the bushing, and the bushing is connected to the stirring rod through a bearing. By setting the bushing, after the propulsion and walking device moves forward to the position, the bushing is inserted into the sleeve to achieve the sealing of the sleeve and prevent material from leaking through the sleeve.
