The end cover assembly comprises a guide rod, the guide rod freely penetrates through a hole in the connecting rod, a limiting plate is in threaded connection with one side, located on the connecting rod, of the guide rod, a spring is sleeved on the other side, located on the connecting rod, of the guide rod, and the spring tightly pushes a cover plate at the end of the guide rod against a furnace material opening.
And a baffle is arranged on one side of the cover plate, which is far away from the furnace charge opening.
The utility model relates to a steel ball heat treatment furnace charge door adjustment mechanism capable of improving quenching quality, which has the following technical effects: by adopting the connecting rod capable of horizontally rotating, the connecting rod is driven to rotate by the gear rack mechanism, and then the cover plate is tightly pressed on the furnace opening, so that the caliber of the furnace opening is reduced, small flow of steel balls falls down during discharging, each steel ball can be uniformly quenched, and the quality is ensured. When feeding, the connecting rod can be driven reversely, so that the cover plate is far away from the furnace charge opening, and the furnace charge opening is kept in a normal larger state, thereby facilitating feeding. In addition, the cover plate is ensured to be tightly attached to the furnace material port by adopting a spring to compress and maintain pressure.

Detailed Description
As shown in figure 1, the adjusting mechanism for the furnace charge opening of the steel ball heat treatment capable of improving quenching quality comprises a support 1, wherein the support 1 is fixed on a furnace body and is positioned on one side of a furnace charge opening 6. The rotating shaft 2 is rotatably arranged on the support 1 through a bearing, the lower end of the rotating shaft 2 is coaxially connected with the gear 3.1, the gear 3.1 is meshed with the rack 3.2, one side of the rack 3.2 is arranged on the sliding rail 3.3 in a sliding mode through the sliding block, and the sliding rail 3.3 is fixed on the support 1. One end of the rack 3.2 is connected with the cylinder 3.4 through an ear plate, and the cylinder body of the cylinder 3.4 is fixed on the furnace body. The rack 3.2 is driven to move back and forth by the cylinder 3.4, the rack 3.2 drives the gear 3.1 to rotate, and the gear 3.1 rotates to drive the rotating shaft 2 to rotate.
One side of the rotating shaft 2 is fixedly welded with the connecting rod 4, the other end of the connecting rod 4 is provided with a through hole, and the guide rod 5.1 freely penetrates through the through hole in the connecting rod 4. The guide rod 5.1 is located that one side of connecting rod 4 is threaded connection with limiting plate 5.2, the guide rod 5.1 is located that the other side of connecting rod 4 is overlapped and is equipped with spring 5.3, the end of guide rod 5.1 on one side of spring 5.3 is fixed with apron 5.4, the external diameter size of apron 5.4 matches with the diameter of charge door 6, be equipped with the turn-ups on the apron 5.4, when apron 5.4 presses on charge door 6, the turn-ups of apron 5.4 laminates the outer wall of charge door 6, the body of apron 5.4 covers the region of three fourths of charge door 6, the region of one of remaining four in the lower part of charge door 6 is used for the ejection of compact.
