Claims

1. A tail section of a horizontal tubular chain conveyor, comprising a tail section housing (22), wherein the front end wall of the tail section housing (22) is symmetrically provided with two reducing pipes (6) that connect to the tubular chain conveying pipeline, characterized in that: The tail box (22) is equipped with a sprocket shaft system (8). The sprocket (8f) of the sprocket shaft system (8) is fixed to the lower end of the tail shaft (8a). The upper part of the tail shaft (8a) is supported in the bearing seat (8e) by a bearing. The bearing seat (8e) is fixed on the slide plate (13a). The slide plate (13a) is slidably engaged with the slide rod (13b) through the slide block (13c), so that the sprocket shaft system (8) can move back and forth along the chain tension direction. A cylinder (19) is fixed to the rear end wall of the tail box (22). The piston rod of the cylinder (19) is drivenly connected to the slide plate (13a). The tail box (22) has nozzles (7) at its four inner corners for spraying and cleaning the inner cavity of the tail box (22). The bottom of the tail box (22) has a cone (9) and a drain outlet (12) at the lowest point of the cone (9).

2. The tail section of the horizontal tubular chain conveyor according to claim 1, characterized in that: At least one side wall of the tail section (22) is provided with a dry air inlet (3), which is connected to an external clean compressed air or hot air source.

3. The tail section of the horizontal tubular chain conveyor according to claim 1, characterized in that: A proximity switch (15) is fixed on the slide plate (13a), and a sensor plate (14) matching the proximity switch (15) is fixed on the inner wall of the tail box (22). When the chain breaks or derails, the slide plate (13a) moves backward, causing the proximity switch (15) and the sensor plate (14) to become misaligned, and the system will issue an alarm and stop.

4. The tail section of the horizontal tubular chain conveyor according to claim 1, characterized in that: The upper port of the tail box (22) is provided with a detachable maintenance door (1), and a maintenance door sealing gasket (21) is provided between the maintenance door (1) and the flange of the tail box (22); a protective screen (10) is also provided below the maintenance door (1).

5. The tail section of the horizontal tubular chain conveyor according to claim 1, characterized in that: The upper port of the bearing housing (8e) is fitted with a self-aligning roller bearing (8d) and the upper port is fixed with an upper bearing cap (8c). The lower port of the bearing housing (8e) is fitted with a deep groove ball bearing (8j) and the lower port is fixed with a lower bearing cap (8k). The outer ports of the upper bearing cap (8c) and the lower bearing cap (8k) are respectively fitted with skeleton oil seals.

6. The tail section of the horizontal tubular chain conveyor according to claim 1, characterized in that: The tail box (22) is provided with vertical supports at the four outer corners. Each vertical support is fixed with a clamp (5) at both the upper and lower ends. The upper part of the support leg (4) is adjusted and fastened by the clamp (5), so that the tail height can be steplessly adjusted on site.
