Description

Technical Field

[0001] The utility model relates to the technical field of unloading materials of a raw coal pile, in particular to a unloading chute mechanism of a raw coal pile. Background Art

[0002] Raw coal refers to the product produced by coal mines without washing, screening and processing, but only after manual sorting of gangue and debris. It includes natural coke and low-quality coal, but does not include low calorific value coal (such as stone coal, peat, oil shale, etc.), and raw coal is mostly stored in piles after production.

[0003] After the raw coal is piled up, it is usually discharged through a chute. However, the accumulation of raw coal easily leads to an extrusion structure, and direct discharge will cause pipeline blockage, so it needs to be improved. Utility Model Content

[0004] The utility model aims to provide a material chute mechanism for a raw coal pile to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a material chute mechanism for a raw coal pile, comprising a bearing base, an exhaust pipe, a receiving hopper and a material chute body,

[0012] Preferably, a discharge pipe is embedded and fixed on the side end surface of the material chute body, and the discharge pipe is connected to the material chute body. The discharge pipe is connected to the material chute body, so that the raw coal entering the material chute body can be discharged through the discharge pipe.

[0013] Preferably, a support block is welded to the bottom end surface of the bearing base, and there are four support blocks in total, and the four support blocks are distributed in a rectangular array relative to the bearing base. The bearing base can be supported and installed by installing the four support blocks in the foundation.

[0014] Preferably, a filter is installed in the exhaust pipe, and the exhaust pipe is in gas communication with the material chute body. The filter is installed in the exhaust pipe, so that the gas in the material chute body can be discharged through the exhaust pipe, and the filter is used to prevent the raw coal from entering the exhaust pipe during discharge.

[0015] Preferably, a filter element is fitted on the inner wall of the housing, and the housing is in gas communication with the exhaust pipe. The filter element is fitted on the inner wall of the housing, so that the gas discharged into the housing is discharged through the filter element, thereby preventing particulate matter in the gas from being discharged together and affecting the surrounding environment.

[0016] Preferably, an air outlet pipe is embedded and fixed on the shell, and a fan is arranged in the air outlet pipe. By arranging the fan in the air outlet pipe, a person can turn on the fan to extract the gas in the shell.

[0017] Preferably, a driving motor 1 is installed on the bottom end surface of the material discharge chute body, and a spiral blade is arranged on the output shaft of the driving motor 1 through a connecting shaft.

[0019] 1. The utility model provides a receiving hopper. When personnel discharge raw coal, they can connect the receiving hopper with the bottom end surface of the raw coal pile bin, so that the raw coal can be directly discharged into the receiving hopper. When discharging, the personnel can turn on the driving motor 2 to drive the stirring rod to rotate through the rotating shaft, so that the raw coal entering the receiving hopper can be broken up when the stirring rod rotates, so as to avoid agglomeration of raw coal after accumulation and affect the subsequent discharge. At the same time, the raw coal can be discharged into the discharge chute body.

[0020] 2. The utility model sets a material discharge chute body. When the raw coal is broken up and discharged into the material discharge chute body, the personnel can turn on the driving motor to drive the spiral blade to rotate through the connecting shaft, so that the spiral blade can drive the raw coal to be transported through the material discharge chute body and reach the discharge pipe for discharge when rotating, avoiding blockage during material discharge. In addition, the personnel can install a heating mechanism on the inner wall of the material discharge chute body to heat and dry the raw coal when discharging, avoiding the raw coal from getting damp due to long-term stacking, and the gas generated by heating can be discharged through the exhaust pipe. When discharging, the gas can be discharged by extraction of the fan, and can be discharged after filtering through the filter element, avoiding the exhaust gas from affecting the surrounding environment.
