。<Prior art> Coal feeding devices of coal charging cars currently in operation have not been equipped with coal pressurization equipment, and coal feeding systems such as a turntable method, screw feeder method, or dead weight drop method have been used. However, in order to improve coke strength and homogenize the packing density in the coking chamber in the height direction, coal is intermittently fed into the coke oven while the coal is being charged from the coal storage hopper into the coke oven. A method of performing consolidation and charging work (problem to be solved by the invention) However, with this method, the time required to charge coal into a coke oven becomes extremely long due to the intermittent consolidation work, which is the current problem. The working time of the coal charging car is a batch operation of 6 to 7 minutes for each furnace chamber, and considering the time for other work such as attaching/detaching the charging lid, driving, coal receiving, etc., the net coal charging time is approximately 2. Although it is a common tax,
In the above method, the source equipment is an existing coal charging vehicle equipped with a coal compaction device, and the coal compaction time is required in addition to the coal charging time. For example, if this consolidation time is assumed to be 2 minutes, which is the same as the coal charging time, the operation cycle will be 8 to 9 minutes, which means that the current coke oven operation will take a long time, and the efficiency of coke oven operation will be improved. On the contrary, it had the disadvantage of causing harm.

特徴とする。Means for Solving Problems〉 The present invention compresses and consolidates coal in advance before charging it into a coke oven, improves the yield of the amount of coal charged, and improves operational efficiency. The aim is to contribute to improving the strength of the coke produced by increasing the applied density. The diameter of the cutting edge circle of the screw blade of the conical spiral conveyor installed in the hopper is gradually reduced, and the pitch of the screw blade is made constant. The feature is that the coal in the coal storage hopper is compacted and cut into the coke oven.
