Detailed Description

The following detailed description of the preferred embodiments will be made with reference to the accompanying drawings.

As shown in figures 1 and 2, the invention provides a dead weight type scraper, which comprises a frame 1 arranged on a conveyor belt, wherein a rotating mechanism is arranged in the frame 1, the rotating mechanism is connected with one end of a pressure rod 2, a scraper 3 at the other end of the pressure rod 2 is connected, the surface of the scraper is connected with the frame through a pressurizing mechanism, the pressurizing mechanism is used for applying downward pressure to the pressure rod 2 and can adjust the size of the pressure rod, the scraper 3 moves downwards under the action of self gravity through the rotating mechanism to drive the pressure rod 2 to rotate around the connection part of the pressure rod and the rotating mechanism, and meanwhile, the pressurizing mechanism is used for applying downward pressure to the pressure rod 2, so that the scraper 3 is always arranged close to the conveyor belt, and the cleaning work of the surface of the conveyor belt in the movement is completed. Like this, along with going on continuously of cleaning, scraper blade 3 can be slowly worn and torn, and with the help of slewing mechanism, scraper blade 3 can continue conveyer belt motion down under the effect of self gravity, utilizes loading system can adjust its size of exerting down force to depression bar 2 simultaneously to both can further ensure scraper blade 3 and hug closely the conveyer belt all the time, provide the guarantee for cleaning, can make full use of scraper blade 3 again, reduce the change number of times, improve work efficiency.

Specifically, this slewing mechanism includes pivot 4, and this pivot 4 is on a parallel with the width direction setting of conveyer belt, and its both ends are connected with frame 1 respectively, and the cover is equipped with sleeve 5 on it, rotates through a plurality of bearings 6 between the two and connects, and the inner circle of this bearing 6 and the external diameter cooperation of pivot 4, and the internal diameter cooperation of its outer lane and sleeve 5 are connected with the one end of depression bar 2 in the central authorities on sleeve 6 surface, can adopt threaded connection. Thus, under the action of the bearing 6, the sleeve 5 can rotate relative to the rotating shaft 4, the pressure lever 2 on the sleeve can rotate relative to the rotating shaft, and other types of rotating mechanisms can be adopted, and the rotating mechanism formed by the rotating shaft 4, the sleeve 5 and the bearing 6 is adopted, so that the structure is simple, the realization is convenient, and the reliability is high.

As shown in fig. 3, the pressurizing mechanism includes a spring 7, a first pressing plate 8 and a second pressing plate 9 are respectively disposed at two ends of the spring 7, a screw 10 is disposed on the first pressing plate 8, the screw 10 is exposed outside through the frame 1 and is in threaded fit with the frame, a fixing pin is disposed on the second pressing plate 9 and is in fit with a positioning hole on the pressing rod 2, and when the spring 7 needs to be replaced, the fixing pin can be pulled out from the positioning hole, and the first pressing plate 8 and the second pressing plate 9 can be replaced integrally. Also can set up left L shape spring catch 11 and right L shape spring catch 12 respectively at spring 7 and first preforming 8 or the hookup location of second preforming 9, it all is L shape, one end is connected with first preforming 8 or second preforming 9, the other end inserts in spring 7, both bilateral symmetry set up, block spring 7 between first preforming 8 or second preforming 9, can take it off from left L shape spring catch 11 and right L shape spring catch 12 through the compressive deformation of spring itself again simultaneously, make things convenient for spring 7's dismantlement.

No matter which kind of above-mentioned loading system, along with the wearing and tearing of scraper blade 3, under its self action of gravity, scraper blade 3 can continue downstream, drive depression bar 2 and second preforming 9 downstream, distance grow between first preforming 8 and the second preforming 9 like this, spring 7 will reduce to the elasticity of depression bar 2, guarantee that it hugs closely the conveyer belt all the time, just need give its bigger holding down force, just can rotate screw rod 10 downwards this moment, make it promote first preforming 8 and press to spring 7, reduce the distance between first preforming 8 and the second preforming 9, make the compressed state before the shorter or recovery of spring 7 compressed, thereby provide enough big holding down force, it provides the guarantee to hug closely the conveyer belt all the time for scraper blade 3.

This frame 1 can adopt to be "[" shape structure, and its two "-" shape lateral walls set up the both sides at the conveyer belt, can adopt welding or bolt fastening's mode, respectively sets up a through-hole in the corresponding position of two "-" shape lateral walls, and this through-hole and pivot 4 cooperation can set up clamp plate 13 on the one side that this frame 1 "|" shape roof is close to the conveyer belt, and this clamp plate 13 can be decided according to actual conditions, like this, all need be provided with on clamp plate 13 and "|" shape roof with screw rod 10 complex screw hole. The other end of the pressure bar 2 penetrates through the frame 1, extends to the outside of the frame 1 and is connected with the scraper 3.

The scraper 3 is of a rectangular structure, the bottom surface of the scraper is matched with the conveying belt, the top surface of the scraper is connected with the connecting plate 14, the connecting plate 14 is provided with a through hole matched with the pressure rod 2, and the scraper and the connecting plate are in threaded connection, so that the scraper 3 is convenient to replace. The material receiving boxes can be arranged on the two sides of the width direction of the conveying belt and close to the scraper 3, and are used for receiving dirt cleaned by the scraper, so that the dirt is prevented from falling off, and the cleaning by an operator is facilitated.

The working process of the scraper for scraping materials is as follows:

firstly, fixing a frame 1 on steel structure frames at two sides of a belt conveyor or a disc edge structure frame of a disc pelletizer, and adopting welding or bolt connection; then the bottom surface of the scraper 3 is fully contacted with the conveyer belt by adjusting the screw 10 above the frame 1, and the scraper 3 can clean the materials on the surface of the scraper and fall into a scraper box or a pelletizing disc in the running process of the conveyer belt or the disc pelletizer.

When meetting hard material, can make 2 lifts of depression bar with the help of slewing mechanism, the spring above that can receive external force automatic compression, plays a cushioning effect, at this moment, just so can effectively avoid leading to the conveyer belt too big and stop or cause the damage to equipment at the operation in-process resistance because of scraper blade 3 and conveyer belt frictional force are too big.

Along with the gradual wearing and tearing that scraper blade 3 used, at the beginning, under the combined action of scraper blade 3 self gravity and loading system, still can hug closely the conveyer belt all the time, but its whole hug closely the power can slowly reduce, when reducing to a certain extent, just need readjust the screw rod 10 of frame 1 top, with its downwardly rotating, further push down first clamp plate 8, reduce the distance between first preforming 8 and the second preforming 9, make the spring 7 compressed shorter or the compression state before resuming to provide sufficient overdraft, make scraper blade 3 hug closely the conveyer belt again.
