Description

Technical Field

[0001] This invention relates to the field of scraper conveyor technology, and in particular to a novel adjustable scraper conveyor center trough. Background Technology

[0002] Coal in my country is widely distributed across different regions, and even within the same mining area, coal seam conditions are highly complex. Different mining conditions require different fully mechanized mining equipment. Therefore, to meet the actual needs of different mining operations, different models of coal mining machines are needed, and correspondingly, different sizes of scraper conveyors are required. Among these, the most important dimensions are the distance from the center of the toothed rail to the center of the scraper conveyor trough and the height of the toothed rail seat. As a crucial component of the scraper conveyor, the toothed rail seat is the track on which the coal mining machine travels. The toothed rail is fixed to the toothed rail seat by pins; therefore, the ultimate influencing factors are the distance D from the center of the toothed rail seat to the center of the scraper conveyor trough and the height H.

[0003] Existing scraper conveyor toothed rail seats are fixed to the trough side by welding. Therefore, scraper conveyors of the same model cannot achieve universal interchangeability due to differences in center distance and height. This results in a significant increase in mining costs and waste of resources. Furthermore, once the tongue plate of the central trough structure wears to a certain extent, it requires major repairs and replacement of the entire central plate or even the entire trough section, which is very costly and time-consuming. Therefore, we propose a new type of adjustable scraper conveyor central trough to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel adjustable scraper conveyor trough.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel adjustable scraper conveyor with a central trough includes a machine body, a central plate on the machine body, a tongue plate mounted on the central plate via a detachable structure, a baffle groove fixedly mounted on one side of the machine body, an adjustment plate placed on top of the machine body and the baffle groove, a pad placed on top of the adjustment plate, and a toothed rail seat slidably mounted on the pad.

[0007] A T-shaped rail is fixedly installed on the top of the pad, and a T-shaped groove adapted to the T-shaped rail is opened on the toothed rail seat. A vertical plate is fixedly installed on the top of the pad, and a hydraulic cylinder is fixedly installed on one side of the vertical plate. The output shaft of the hydraulic cylinder is fixedly connected to the toothed rail seat.

[0008] Mounting plates are fixedly installed on both sides of the toothed rail seat. The mounting plates have elongated holes in which locking bolts are placed. The pads have bolt grooves, and the locking bolts are matched with the bolt grooves.

[0009] The top of the body and the baffle groove are both provided with threaded grooves. The adjustment plate is provided with a first mounting hole and the pad is provided with a second mounting hole. Fixing bolts are placed in the first and second mounting holes, and the fixing bolts are compatible with the threaded grooves.

[0010] Preferably, the top of the T-shaped track is provided with a movable groove, a movable seat is slidably installed in the movable groove, and a wedge is installed on the top of the movable seat through a detachable structure, and the wedge is adapted to the T-shaped groove.

[0011] Preferably, a threaded hole is provided on one side of the inner wall of the movable groove, and an adjusting screw is installed in the threaded hole. One end of the adjusting screw is rotatably mounted on the movable seat, and the other end of the adjusting screw is fixedly mounted with a handle.

[0012] Preferably, the movable groove has a rotating groove, the inner wall of the rotating groove has an annular groove, and an annular seat is fixedly installed on the adjusting screw, and the annular seat is rotatably connected to the corresponding annular groove.

[0013] Preferably, a rectangular seat is fixedly installed on the top of the baffle groove, and a lifting mechanism is provided between the rectangular seat and the pad.

[0014] Preferably, the lifting mechanism includes a slot, a lifting groove, and a lifting plate. The slot is formed on a pad, the lifting groove is formed on a rectangular base, and the lifting plate is slidably installed in the lifting groove, with the lifting plate being adapted to the slot.

[0015] Preferably, the same threaded rod is rotatably installed on the top and bottom inner walls of the lifting groove, and the lifting plate is threaded onto the threaded rod. One of the two threaded rods extends to the top of the rectangular seat and is fixedly installed with a knob.

[0016] Preferably, a pulley is fixedly installed on the threaded rod, and the two pulleys are driven by the same belt.

[0017] Preferably, limit grooves are provided on the inner walls of the front and rear sides of the lifting groove, and limit seats are fixedly installed on the front and rear sides of the lifting plate, with the limit seats slidably connected to the corresponding limit grooves.

[0018] Preferably, the top of the lifting groove is provided with a rotating hole, and the threaded rod is rotatably connected to the corresponding rotating hole.

[0019] The beneficial effects of this invention are:

[0020] 1. When adjusting the distance between the toothed rail seat and the center position of the scraper conveyor groove, the hydraulic cylinder is activated. The hydraulic cylinder can drive the toothed rail seat to move through the output shaft, thereby adjusting the position of the toothed rail seat and the center position of the scraper conveyor groove. After the adjustment is completed, the wedge can be inserted into the T-slot by the cooperation of the handle, adjusting screw, threaded hole, moving seat and wedge, thus initially fixing the toothed rail seat.

[0021] 2. When the gear rail seat moves the mounting plate, the position of the locking bolt in the elongated hole changes. By rotating the locking bolt, the locking bolt can be screwed into the bolt groove, and the locking bolt can press the mounting plate, thereby achieving the purpose of reinforcing the gear rail seat.

[0022] 3. When adjusting the height of the gear rack seat, the screw rod, pulley, belt, and screw rod work together to move the lifting plate upwards. The lifting plate then moves the pad upwards, allowing the adjusting plate to be replaced. When different thickness adjusting plates are used, the pad and adjusting plate are fixed by the fixing bolts and threaded grooves, thus achieving the purpose of adjusting the height of the gear rack seat.
