Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine mechanical equipment, and in particular relates to a head baffle box of a transfer machine. Background Art

[0002] The transfer machine is a crucial component of the transportation system for a comprehensive mechanized coal mining face. In the face's equipment layout, its tail is connected to the scraper conveyor below the shearer, and its nose is attached to the tail section of the belt conveyor. Mined coal is transferred via the scraper conveyor to the transfer machine, where it is lifted by the overhead section of the transfer machine and dropped onto the belt conveyor.

[0003] In the real world of coal transfer, the varying sizes of coal lumps create varying momentum upon leaving the transfer machine. This causes the coal to scatter and fall unconcentrated onto the belt conveyor, leading to additional labor costs and safety hazards. Therefore, the transfer machine's head is equipped with a baffle, which primarily functions to converge the coal flow and cushion the impact of the coal lumps. The baffle's main structure consists of a frame, internal baffles, and tie rods securing the baffles. Adjusting the baffle's opening and closing angle adjusts the coal flow convergence. After the baffle is adjusted to the desired angle, a pin is used to secure the baffle to the baffle, which then connects to holes in the baffle to secure the baffle. However, current fixing methods have two significant issues: first, the holes in the tie rod are machined at 7.5° intervals, preventing fine-grained adjustment. Second, the baffle cannot be adjusted simultaneously while the transfer machine is running; the baffle's opening and closing angle must be adjusted only when the transfer machine is stopped, potentially leading to serious safety hazards. Therefore, it is necessary to solve the above two problems and realize the structural optimization and upgrading of products. Utility Model Content

[0006] Two parallel first connecting ribs are arranged on the outer side of the box body plate, a first connecting shaft is arranged on the first connecting rib, and one end of the driving cylinder is rotatably arranged on the first connecting shaft.

[0007] The first connecting rib is arranged along the horizontal direction, and the first connecting axis is arranged along the vertical direction.

[0008] Two parallel connecting blocks are also fixedly provided on the baffle, and the connecting blocks pass through the box plate and are rotatably connected to the first connecting shaft.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments; based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, an embodiment of the utility model provides a head baffle box of a transfer machine, comprising a baffle box body 1 and baffles 2 rotatably arranged on both sides of the baffle box body 1. Specifically, a driving cylinder 3, a bending plate 4 and a slide plate 5 are respectively provided on the box plates 9 on both sides of the baffle box body 1, and a long slide groove 7 is provided on the slide plate 5; the driving cylinder 3 is arranged on the outside of the baffle box body 1, one end of which is rotatably connected to the box plate 9, and the other end is rotatably connected to one end of the bending plate 4, the middle part of the bending plate 4 is rotatably connected to the box plate 9, and the other end is connected to the slide plate 5 through a sliding pin 8 in the long slide groove 7 provided on the slide plate 5, and the slide plate 5 is fixedly connected to the corresponding baffle 2.

[0022] Specifically, in this embodiment, two parallel first connecting ribs 10 are provided on the outer side of the box plate 9 , a first connecting shaft 11 is provided on the first connecting rib 10 , and one end of the driving cylinder 3 is rotatably provided on the first connecting shaft 11 .

[0023] Furthermore, in this embodiment, the first connecting rib 10 is arranged along the horizontal direction, and the first connecting axis 11 is arranged along the vertical direction.

[0024] Specifically, in this embodiment, two parallel connecting blocks 14 are fixedly provided on the baffle 2 , and the connecting blocks 14 pass through the box plate 9 and are rotatably connected to the first connecting shaft 11 .

[0025] Furthermore, in this embodiment, two parallel second connecting ribs 12 are provided on the outer side of the box plate 9 , a second connecting shaft 13 is provided on the second connecting rib 12 , and the middle portion of the curved plate 4 is rotatably provided on the second connecting shaft 13 .

[0026] Furthermore, in this embodiment, the second connecting rib 12 is arranged along the horizontal direction, and the second connecting axis 13 is arranged along the vertical direction.

[0027] Furthermore, in this embodiment, if Figure 3 As shown, there are two slide plates 5, the other end of the curved plate 4 is arranged between the two slide plates 5, the middle of the sliding pin 8 is passed through the long slide groove 7 in the curved plate 4, and the two ends are respectively arranged in the long slide groove 7 on one of the slide plates 5.
