Internal motor driven silo center unloader

Abstract

The invention relates to a silo center discharging machine driven by internal motors. The silo center discharging machine driven by the internal motors comprises a pressure reduction cone arranged inside a silo, the pressure reduction cone is arranged in the center of the bottom of the silo through a supporting beam in an erecting mode, the driving motors and slewing bearings are arranged on a bottom plate inside the pressure reduction cone, and fixed rings of the slewing bearings are fixed to the bottom plate. A through hole is formed in the center of the bottom plate, a main shaft is arranged in the through hole, the end, stretching into the pressure reduction cone, of the main shaft is sleeved with a shaft sleeve, and the end, stretching out of the pressure reduction cone, of the main shaft is provided with a discharging arm. The shaft sleeve on the main shaft is connected with movable rings of the slewing bearings. A silo bottom flange is connected with a bottom tray, a discharge port is designed in the middle of the bottom tray, and a discharge pipe and compensator are arranged in the discharge port. The silo center discharging machine driven by the internal motors can automatically adjust the discharge speed and meet the discharge requirement for first-in first-out; meanwhile, materials are separated from the driving part and the outside completely, absolute advantages are achieved on the onsite environment and equipment protection, the structure is simplified, and all the requirements for the actions and the stress of the equipment can be achieved with lower cost.

Description

technical field [0001] The invention relates to an unloading machine, in particular to a silo center unloading machine driven by an internal motor, which belongs to the technical field of bulk material loading and unloading equipment. Background technique [0002] At present, in most domestic bulk material industries, such as coal power, grain, cement, paper, etc., silos are used more and more. With the development of silos, the demand for silo unloaders is gradually expanding. However, The discharge equipment at the bottom of the silo is far from keeping up with the speed of silo promotion. In many industries, silos still use the original methods such as gravity self-unloading. In this way, the loose material in the silo has serious problems such as clogging, sticking, and knotting, which is time-consuming and cost-effective. It costs materials and money, and some existing structural equipment have their own advantages and disadvantages. For example, the externally driven u...

[0002] At present, in most domestic bulk material industries, such as coal power, grain, cement, paper, etc., silos are used more and more. With the development of silos, the demand for silo unloaders is gradually expanding. However, The discharge equipment at the bottom of the silo is far from keeping up with the speed of silo promotion. In many industries, silos still use the original methods such as gravity self-unloading. In this way, the loose material in the silo has serious problems such as clogging, sticking, and knotting, which is time-consuming and cost-effective. It costs materials and money, and some existing structural equipment have their own advantages and disadvantages. For example, the externally driven unloader has leakage phenomenon, while the cost of the equipment driven by the built-in planetary structure remains high, resulting in the market but An embarrassing situation that is difficult to implement
