Technical Field

[0001] The utility model relates to the technical field of slag scrapers, in particular to an ore conveying scraper trough of a slag scraper. Background Art

[0002] Mud scraper has important uses in tunnel excavation, mining projects, water conservancy projects and other projects. It is an important construction machinery. Mud scraper, also known as excavator loader, combines the mucking arm with the conveying device to combine the mucking and conveying and loading functions into one. It has the advantages of safety, environmental protection, low energy consumption and high efficiency.

[0003] In the prior art, when the conveying scraper trough of the scraper is conveying ore, fine crushed stone particles and dust are easily attached to the scraper chain and the scraper. The long-term accumulation of dust can easily cause the chain to jam and affect the service life of the chain. The device is not convenient for cleaning the dust, and the manual cleaning efficiency of the staff is low. In addition, the scraper in the scraper trough will be severely worn after working for a long time, resulting in low ore conveying efficiency. Utility Model Content

[0004] The utility model aims to provide a scraper ore conveying scraper trough, which can timely clean the scraper and chain, timely replace the scraper, and maintain the conveying work efficiency.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a scraper ore conveying scraper trough, including a scraper body, a conveying scraper trough installed on the scraper body, a conveying chain transmitted along the direction of the conveying scraper trough and scrapers fixed on both sides of the conveying chain, a cleaning brush and a driving component for driving the cleaning brush to move up and down are installed on one side of the conveying scraper trough, mounting plates are fixed on both sides of the conveying chain, and the mounting plates are slidably connected with a locking rod inserted between the scraper and the mounting plate.

[0006] By adopting the above technical solution, when the device is used for cleaning, the driving component drives the cleaning brush to move up and down to scrape off the gravel, dust and the like on the scraper and the conveyor chain, thereby avoiding the accumulation of gravel on the scraper and the conveyor chain to affect the conveying work efficiency and improve the service life of the device; the scraper and the mounting plate are relatively fixed or disassembled by the locking rod to replace the worn scraper to maintain the conveying work efficiency.

[0007] The utility model is further configured as follows: the driving assembly includes a fixed frame, a support frame fixed to the fixed frame, a driving motor installed on the support frame and a turntable fixed to the output end of the driving motor, the turntable is eccentrically fixed with a rotating rod, the support frame is slidably connected with a movable rod, the movable rod is provided with a limiting groove for the rotating rod to extend into, and the cleaning brush is installed at the bottom end of the movable rod.

[0008] By adopting the above technical solution, when the device is used for cleaning, the drive motor is started, and the output end of the drive motor drives the turntable to rotate, so that the turntable drives the movable rod and the cleaning brush to move back and forth up and down through the rotating rod and the limit groove to scrape off the gravel, dust, etc. on the scraper and the conveyor chain, and the cleaning efficiency is high.

[0009] The utility model is further configured as follows: the upper and lower ends of the movable rod are inserted and slidably connected between the fixing frame and the supporting frame.

[0010] By adopting the above technical solution, the fixed frame and the support frame jointly limit the movable rod that moves up and down, so that the movable rod drives the cleaning brush to move up and down and the cleaning process is more stable.

[0019] The utility model is further configured as follows: the first through holes are provided in two upper and lower portions.

[0020] By adopting the above technical solution, the relative fixation between the mounting plate and the scraper is made more secure.

[0021] The utility model is further configured as follows: a connecting plate is fixed between the ends of the upper and lower locking rods, and a locking spring sleeved on the outside of the locking rod is fixed between the connecting plate and the mounting plate.

[0022] By adopting the above technical solution, the upper and lower locking rods are pulled together through the connecting plate, so that the end of the locking rod extends out from the second through hole, so that the first through hole is connected to the second through hole after the side connecting block of the scraper is embedded in the connecting groove, and the locking rod is released. The locking rod is sequentially inserted into the second through hole on one side of the connecting groove, the first through hole on the connecting block and the second through hole on the other side of the connecting groove to complete the relative fixation between the mounting plate and the scraper.

[0023] The utility model is further configured as follows: one end of the locking rod away from the connecting plate extends through the mounting plate, and baffles for shielding the two ends of the locking rod are fixed on both sides of the mounting plate.

[0024] By adopting the above technical solution, the baffle shields and protects both ends of the locking rod to prevent the locking rod from being pushed during transportation or under other effects such as ore, making the relative fixation between the mounting plate and the scraper more stable.
