When the coal mill stone coal is discharged and transported through the manual trolley, a large amount of dust can be caused when the coal mill stone coal is discharged, and the labor is wasted in the discharging process and the discharging is slow.
Disclosure of Invention
The utility model aims to provide a coal mill pebble coal discharging trolley, which mainly solves the technical problems that a large amount of dust is easily caused in the use process of the coal mill pebble coal discharging trolley of a thermal power plant, manpower is wasted in the discharging process, the discharging is slow and the like.
The above object is achieved by the following technical scheme:
the utility model provides a coal pulverizer stone coal discharges dolly, includes, dolly and material case, the dolly with the material case connect, the platform of dolly on be provided with manual hydraulic means, manual hydraulic means with the dolly between pass through bolted connection, manual hydraulic means constitute by hydraulic pump and footboard, the footboard respectively with hydraulic pump and dolly afterbody rotate to be connected, the hydraulic pump pass through the bolt with the material case connect, the platform of dolly on install the otic placode, the otic placode is intraductal to penetrate and is constituteed the revolute pair, revolute pair rotates with the riser of material case below to be connected.
The stone coal discharging trolley of the coal mill is characterized in that a stone coal outlet pipe is arranged above the material box, the diameter of the stone coal outlet pipe is smaller than that of a stone coal inlet on the material box, and the stone coal outlet pipe is in soft connection with the stone coal inlet pipe.
The stone coal discharging trolley of the coal mill is characterized in that a slag discharging door is arranged at the end part of the material box, and the slag discharging door is rotationally connected with the material box.
The utility model has the beneficial effects that:
1. according to the utility model, in the unloading process, one side of a pebble coal box body for storing pebble coal on a pebble coal trolley is jacked up by a manual hydraulic device and kept still, so that a certain included angle is formed, and the pebble coal is poured out from the inner part of the box body by itself under the action of gravity. Saving manpower and time.
2. The upper part of the material box body is provided with the circular pebble coal inlet pipe, the pipe diameter of the circular pebble coal inlet pipe is larger than that of the pebble coal outlet pipe of the coal mill, and when the pebble coal is discharged, the pebble coal outlet pipe is arranged at the lower part of the pebble coal inlet pipe and is in a flexible connection mode, so that a certain seal can be formed, and dust emission is reduced.
3. According to the utility model, the slag discharging door on the material box body is connected with the box body through the bolts, so that the rotation can be realized and the slag discharging door does not fall off. The labor intensity output of workers who discharge stone coal is saved, the working efficiency is improved, and the dust caused by stone coal discharge is reduced. Meanwhile, the manual labor force is reduced, the operation time of the whole discharging process is shortened, and the dust emission of coal dust is reduced.

Detailed Description
Examples
The utility model provides a coal pulverizer stone coal discharges dolly, includes, dolly 1 and material case 2, the dolly with the material case connect, the platform of dolly on be provided with manual hydraulic means, manual hydraulic means with the dolly between pass through bolted connection, manual hydraulic means constitute by hydraulic pump 3 and footboard 4, the footboard rotate with hydraulic pump and dolly afterbody respectively and be connected, the hydraulic pump pass through the bolt with the material case be connected, the platform of dolly on install otic placode 5, the intraductal revolute pair 6 that has constituteed of having the pivot of otic placode, the revolute pair rotates with the riser 7 of material case below and is connected.
Examples
According to the coal pulverizer pebble coal discharging trolley of the embodiment 1, a pebble coal outlet pipe 8 is arranged above the material box, the diameter of the pebble coal outlet pipe is smaller than that of a pebble coal inlet on the material box, and the pebble coal outlet pipe is in soft connection with the pebble coal inlet pipe.
