[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] A transition trough with a replaceable upper edge of a trough rib is provided, wherein a transition trough 1 is provided, wherein the upper end surface of the transition trough 1 is provided with a slope, vertical plates 2 are provided on both sides of the transition trough, and trough ribs 3 are evenly distributed on the transition trough. The trough ribs 3 are placed in pairs on the vertical plates 2, and a plurality of trough ribs 3 form a unit. Within each unit, the trough rib structure is consistent.

[0018] Alternatively, the trough side 3 includes a vertical portion 32 and a horizontal portion 33. The vertical portion 32 abuts against the vertical plate 2 on the transition trough. The vertical portion is provided with a protrusion 32a. The horizontal portion 33 is correspondingly provided with a stopper 33a. The stopper 33a is plugged into the protrusion 32a and fixed together by bolts 4.

The height of the initial positioning protrusion 32b is greater than the height of the positioning protrusion 32c. After positioning with the initial positioning protrusion, fine-tuning is performed, and then the groove side is screwed to the waist hole of the vertical plate 2 by bolts 4 to complete the assembly.

[0022] The working principle of this utility model is:

[0023] Scraper operation process

[0024] Movement of scraper in transition trough

[0025] Driven by the power unit, the scraper moves along the transition trough. Due to the slope on the upper end of the transition trough, the scraper gradually adapts to the transition from one plane to another during operation. During this process, the scraper is in constant contact and friction with the trough side.

[0026] The trough sides are placed in pairs on the vertical plates on both sides of the transition trough. Multiple trough sides form a unit, and the trough side structure is consistent within each unit. The main function of the trough side is to guide the scraper's running direction and prevent it from running off the track.

[0027] The influence of rib structure on scraper operation

[0028] The trough side is an L-shaped structure or a structure consisting of vertical and horizontal sections. It tightly abuts the vertical plates of the transition trough. Whether fixed by pins (L-shaped trough side) or bolted after the protrusions are inserted into the stoppers (vertical and horizontal trough side), the trough side ensures stability during the operation of the scraper. When the scraper passes, the trough side can withstand the lateral force of the scraper, ensuring that the scraper runs along the predetermined track.

[0029] The rounded corners at the edge of the trough serve as a transition, allowing the scraper to pass through the edge of the trough more smoothly, reducing collisions and jams between the scraper and the trough, thereby reducing noise and wear on the scraper and the trough, helping to increase the service life of the scraper and the trough, and ensuring the smooth operation of the scraper.

[0030] The purpose of setting the leveling spacer is to ensure proper fine-tuning during assembly and to ensure the smoothness of the scraper during movement;

[0031] In the transition groove of the replaceable groove upper edge, an initial positioning protrusion is provided in the middle of the vertical portion and its height is greater than the height of the positioning protrusions at both ends of the vertical portion, which has the following functions:

[0032] Initial positioning function: When installing the trough side, the initial positioning protrusion first contacts the transition trough or other related components. Due to its high height, it can quickly guide the trough side into the roughly correct installation position, providing a preliminary positioning reference for subsequent precise installation and facilitating the installation operation.

[0033] Prevent mis-installation: The height difference can prevent the trough side from being installed in the reverse or wrong direction during the installation process, ensuring that the trough side is installed on the transition trough in the correct posture, and ensuring the compatibility and normal operation of the trough side structure with the entire system.

[0034] Improve installation accuracy: After the initial positioning protrusion is initially positioned, the positioning protrusions at both ends further accurately adjust the position of the trough side. The combination of the two helps to improve the overall accuracy of the trough side installation, so that the trough side can better play its function of guiding the scraper operation during use, ensuring the stable operation of the scraper system.

[0035] Principle of groove replacement

[0036] L-shaped groove replacement method

[0037] When the L-shaped channel side needs to be replaced, since it is fixed to the riser by a pin, first remove the pin connecting the channel side and the riser. Then, remove the worn or damaged L-shaped channel side from the riser. Then, align the new L-shaped channel side with the installation position on the riser, insert the pin into the channel side's countersunk hole and the corresponding hole in the riser to complete the installation. This replacement method is simple and convenient, and does not require extensive disassembly or adjustment of other parts of the transition channel.

[0038] Vertical and horizontal structural trough replacement method

[0039] When replacing a trough side with a vertical and horizontal structure, first remove the connecting bolts to release the locking engagement between the stop and the protrusion. Next, remove the trough side to be replaced from the vertical plate. Align the vertical portion of the new trough side with the vertical plate, inserting the protrusion into the stop of the horizontal section, and then secure it with bolts. During this process, horizontal washers are placed on the horizontal working surface to provide adjustment and cushioning. Initial positioning protrusions and positioning protrusions help quickly and accurately position the trough side during installation, improving installation efficiency and accuracy.
