Technical Field

The utility model relates to a mechanical device especially relates to a mechanical device who is applicable to cubic bulk materials such as lump coal, raw coal, waste rock, ore, coke and unloads from belt conveyor.

Background

At present, the main modes of transportation of blocky bulk materials and realization of midway unloading are as follows: 1. a scraper conveyor with a hydraulic inserting plate; 1) the working principle is as follows: an electro-hydraulic inserting plate is arranged below the scraper conveyor at a certain distance according to needs, the process is changed by opening, closing or partially opening the electro-hydraulic inserting plate, and the whole unloading, passing or partial passing of materials is realized. The coal bunker proportioning device is mainly used as a coal bunker proportioning device and a plurality of raw coal classifying screens. 2) The main advantages are that: the multi-point discharging can be carried out, the environment pollution caused by the operation of the materials in the tank box is small, and the use is flexible and convenient. 3) The main disadvantages are that: the transportation distance is not easy to be too long (generally less than 100 m), the transportation power is large (approaching 10 times of a belt conveyor with the same transportation capacity), the manufacturing cost is relatively high, the noise is relatively large, and the production cost is high.

2. The belt conveyor with the discharging trolley 1) has the working principle that a head roller and a guide roller of an upper belt of the discharging trolley form a machine head which can be used for discharging, the machine head travels on a track and simultaneously discharges materials 2) has the main advantages that the machine head is often used for discharging materials of a plurality of coal bunkers or coal storage yards and can realize long-distance multi-point continuous discharging, and the working state is reliable 3) has the main defects that ① and the discharging trolley are high in equipment investment relative to a plow discharger, ② when the belt speed of the belt conveyor is high, the discharging trolley is easy to move along with the belt conveyor, a fixing device with a track is required to be added, and therefore continuous discharging cannot be realized, ③ and the equipment installation space is large, so civil engineering investment is improved, ④, the space and the structural strength of a conventionally designed belt conveyor trestle cannot meet the requirement of increasing the discharging trolley, ⑤ and the belt conveyor must be horizontally arranged.
