Description

Technical Field

[0001] The present invention relates to the technical field of scraper machines, and in particular to a crawler scraper machine and a conveying trough limiting mechanism thereof. Background Art

[0002] For example, the Chinese patent with the announcement number CN213709682U discloses a tire-type scraper conveying limit structure, including a limit plate and a mounting seat, the limit plate is provided at the top of the mounting seat, an adjustment mechanism is provided inside the limit plate, one end of the mounting seat is fixedly connected to a fixing rod, the top of the fixing rod is provided with a buffer structure, and the mounting seat is provided with a structure for facilitating disassembly inside.

[0003] However, the above scheme has the following shortcomings: in the above patent, the extension plate is pulled out from the storage slot, the adjustment holes are aligned and then the locking bolt is tightened, so that the limit plate and the extension plate can be locked and fixed, thereby increasing the height to prevent sliding, and the slag blocks are less likely to slide. The applicability of this structure is relatively strong, but since the feed end of the feed trough in the scraper is relatively open, this results in only the material close to the conveyor belt position entering the front end each time, and more material is often accumulated on both sides of the feed trough. For the material that is finally accumulated on both sides of the feed trough, the operator can only push the material into the conveyor belt position in the conveyor trough through the scraper hopper, which is not convenient to operate.

When the support plate 9 tilts upward, the second belt 3 will be driven to move, and the tensioning pulley 26 in contact with the second belt 3 will be pushed to move, and the movement of the tensioning pulley 26 drives the T-bar 27 to move synchronously, and the first spring 29 is compressed at this time. When the support plate 9 moves downward, the second belt 3 will be re-tightened by the tensioning pulley 26 under the elastic force of the first spring 29;

When the material is scraped to the upper end of the U-shaped mounting plate 1, under the elastic force of the second spring 4, the T-shaped blocking plate 5 bounces up again to block the material;

[0040] In addition, in order to achieve the above-mentioned purpose, the present invention also provides a crawler scraper, including a conveyor trough limiting mechanism and a scraper body 33. A feed trough 30 is provided in the scraper body 33, and a conveyor belt for conveying materials is provided in the feed trough 30.

After the installation is completed, the telescopic cylinder 15 is opened to drive the jacking rod 18 connected to its output end to move upward. The movement of the jacking rod 18 causes the T-shaped slide block 24 to drive the support plate 9 upward. Since the clamping end of the clamping rod 19 is arranged in an inclined shape, when the jacking rod 18 moves upward, the clamping end of the clamping rod 19 will be disengaged from the clamping hole 16. When the clamping end of the clamping rod 19 moves to the position of the new clamping hole 16, under the elastic force of the reset spring 22, the clamping rod 19 is re-clamped into the clamping clamping hole 16.

[0043] By turning on the transmission motor 8, the transmission pulley 7 connected to its output end starts to rotate, and the transmission pulley 7 drives the second pulley 12 to start rotating through the second belt 3. The rotation of the second pulley 12 drives the first pulley 14 connected to it to start rotating. Driven by the first belt 13, several limiting rollers 10 will start to rotate, and the material will be scraped to the upper end of the U-shaped mounting plate 1 through the mechanical arm scraping mechanism 32. In the process of scraping the material, the T-shaped blocking plate 5 will be squeezed to move into the sliding cavity 2, so that the second spring 4 is compressed. When the material is scraped to the upper end of the U-shaped mounting plate 1, under the elastic force of the second spring 4, the T-shaped blocking plate 5 bounces upward again to block the material, and several rotating limiting rollers 10 guide the material to the conveyor belt of the feed trough 30, thereby achieving guidance and limitation of the material.
