DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 10 As shown, a coal quantity adjustable baffle box assembly for a coal mine chute transfer machine includes a head baffle box 1 and an adjusting door 2. The head baffle box 1 is an inverted U-shape, and two adjusting doors 2 are respectively arranged on the left and right sides of the head baffle box 1. The ends of the two adjusting doors 2 that are away from each other are respectively hinged to the head baffle box 1. An adjustable pull rod 4 is arranged between the outer side of the adjusting door 2 and the head baffle box 1. The position of the adjusting door 2 is controlled by the adjustable pull rod 4, thereby controlling the opening between the two adjusting doors 2.

[0029] The adjustable pull rod 4 includes a bent plate 4.1 and a limit ring 4.2. One end of the bent plate 4.1 is hinged to the adjustment door 2. Through holes are provided on both sides of the head stop box 1. The other end of the bent plate 4.1 passes through the through hole and is fixedly connected to the limit ring 4.2. The limit ring 4.2 interferes with the through hole to prevent separation. The bent plate 4.1 is provided with a plurality of limit holes. A positioning pin 4.3 is movably provided on the outer side of the through hole. The positioning pin 4.3 passes through one of the limit holes to achieve relative fixation between the bent plate and the head stop box 1, thereby achieving positioning of the adjustment door 2.

[0030] For the convenience of connection, any adjusting door 2 is provided with two connecting ears, and the head stop box 1 is provided with a hinge shaft 2.1 matching with the connecting ears, and the hinge shaft 2.1 is rotatably arranged on the head stop box 1 and limited by a cotter pin 2.2.

[0031] The left and right sides of the lower end of the head baffle box 1 are respectively provided with a left coal baffle assembly 3 and a right coal baffle assembly 5. The left coal baffle assembly 3 and the right coal baffle assembly 5 both include a coal baffle plate 3.1 and a rubber plate 3.2. The lower end of the coal baffle plate 3.1 is bent to one side. The rubber plate 3.2 is fixedly connected to the lower end of the coal baffle plate 3.1 by bolts and nuts. In order to protect the rubber plate 3.2, a pressure plate 3.6 and a gasket are provided between the nut and the rubber plate 3.2. The upper end of the coal baffle plate 3.1 is provided with a mounting hole 3.3 and an arc hole 3.4. The coal baffle plate 3.1 is hinged to the head baffle box 1 through the mounting hole 3.3. The head baffle box 1 is fixedly connected with a pin shaft 3.5 and is slidably connected with the arc hole 3.4 through the pin shaft 3.5. The coal baffle plate 3.1 and the head baffle box 1 are both connected with an articulated seat. The two ends of the oil cylinder 6 are respectively articulated with two articulated seats. The oil cylinder 6 is connected with an operating valve group 7. By operating the valve group 7 to control the extension or shortening of the oil cylinder 6, the coal baffle plate 3.1 is driven to rotate around the axis of the mounting hole 3.3, and the pin 3.5 and the arc hole 3.4 slide relative to each other to limit the position. When the chute fluctuates, the gap between the head baffle box of the transfer machine and the belt of the belt conveyor is automatically overlapped, solving the problem of coal spillage caused by poor overlap between the head of the transfer machine and the belt due to the fluctuating chute.

[0032] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments.
