Background

The screen grate is positioned below the tipper and above the coal hopper and is used for screening harmful materials such as woven bags, sleepers, wood bars and the like passing through the grate holes. The coal with the granularity smaller than the grate opening falls into the coal hopper and is conveyed to the next procedure through the belt, and in the process of sieving the grate, the coal is easy to bridge and block the grate, and the condition that large coal blocks, wet coal, frozen coal, coal gangue and the like cannot pass through the grate can be generated. Therefore, the sieve grate needs to be matched with sieve grate dredging equipment for use.

The screen grate dredging equipment is easy to slip in the working process, so that the machine is difficult to move back and forth when staying on the coal grate. Therefore, in some travelling devices of the screen grate dredging equipment, besides the steel wheel driving shaft running on the steel rail pushes the steel wheel to travel on the steel rail, a pin gear coaxial with the steel wheel is also arranged, and the pin gear is also connected with the driving shaft to rotate. The pin teeth of the pin gear are matched with the pin racks beside the steel rail, and the power of the motor can be fully converted into walking thrust by adopting a pin tooth forced transmission mode. However, this type of screen grate dredger is inconvenient to maintain and repair when it is out of order.

Through a large amount of researches, the applicant finds that in the conventional screen grate dredging equipment, a steel wheel and a pin gear are coaxially arranged and are connected with a driving shaft. The steel wheel and the pin gear are small in distance, the whole installation space is small, and maintenance is inconvenient. If the pin gear has problems, the installation space is small, and sufficient operation and maintenance space cannot be provided, so that the pin gear can be maintained and repaired after the steel wheel is disassembled. And steel wheel and pin gear are the action wheel, and in order to guarantee transmission efficiency, the precision requirement of its installation is higher, like tolerance and cooperation degree, therefore a large amount of time are all required in single wheel dismouting process, otherwise the condition that the assembly is not in place appears easily. In addition, the steel wheel and the pin gear are both driving wheels, interference phenomenon is easy to occur, when one driving wheel is clamped and cannot advance, the other driving wheel still continues to operate and drive to advance, and the situation that the driving wheels are broken can be caused, for example, the tooth root of the pin gear is cracked and broken. Therefore, the existing sieve grate dredging equipment has the problem of inconvenient maintenance.

Referring to fig. 1 and 2 together, a screen grate dredging apparatus according to an embodiment of the present application will now be described. The screen grate dredging device comprises a track 100 and a body 200 arranged on the track 100, and a pin rack 110 is arranged beside the track 100. The body 200 is provided with a travel driving mechanism 300, a travel wheel 220 and a pin gear 210, the pin gear 210 is arranged on a transmission shaft 310 connected with the travel driving mechanism 300 and corresponds to the pin rack 110, and the travel wheel 220 is matched with the track 100 and is isolated from the transmission shaft 310.

The body 200 may be a steel frame structure that is supported on the rail 100 by a pin gear 210 and a travel wheel 220. The traveling driving mechanism 300 is disposed on the body 200, and may be a motor, an internal combustion engine, or other power mechanism. A pin rack 110 is disposed beside the track 100, and the pin rack 110 includes a plurality of pins engaged with the tooth grooves of the pin gear 210. The walking driving mechanism 300 drives the pin gear 210 to rotate through the transmission shaft 310 and the connection, and drives the pin gear 210 to travel along the pin rack 110.

The traveling wheel 220 is provided on the body 200 without being connected to the driving shaft 310, and thus is a driven wheel. Even though the traveling wheel 220 and the pin gear 210 are still designed to be coaxial, the traveling wheel 220 and the pin gear 210 have larger space between each other due to the fact that the space between the traveling wheel 220 and the pin gear 210 is not limited by the space of the transmission shaft 310, and larger installation and maintenance space is provided for each. Especially, the traveling wheel 220 and the pin gear 210 are arranged in a staggered manner along the axial direction of the transmission shaft 310, the distance between the traveling wheel and the pin gear is further increased, the traveling wheel and the pin gear have larger installation and maintenance spaces, and meanwhile, the contact position between the body 200 and the rail 100 is more dispersed, the acting force is more dispersed, and the stability is better.

In this case, even when the travel wheel 220 or the pin gear 210 requires maintenance, only the wheel requiring maintenance can be maintained, thereby improving maintenance efficiency. And the travelling wheel 220 is a driven wheel, the installation precision requirement is relatively low, and the efficiency is relatively high when the travelling wheel is maintained. Of the travel wheel 220 and the pin gear 210, only the pin gear 210 is a driving wheel, and interference phenomenon is not easy to occur. Even when the pin gear 210 is caught and cannot travel, the apparatus does not continue to travel by the driving of the travel wheel 220, thereby protecting the pin gear 210.

The application provides a screen grate mediation equipment's beneficial effect lies in: compared with the prior art, the pin gear 210 of the screen grate dredging device is connected with the transmission shaft 310 of the walking driving mechanism 300, and the pin gear 110 runs under the driving of the pin gear. The traveling wheel 220 is provided on the body 200 to be isolated from the transmission shaft 310, and is not directly connected to the traveling driving mechanism 300 to be operated. Therefore, the pin gear 210 and the traveling wheel 220 have large installation and maintenance spaces, and when maintenance is needed, corresponding structures can be maintained respectively, so that the maintenance efficiency is improved.

The two sides of the body 200 are respectively provided with a corresponding travelling wheel 220 and a pin gear 210 to be matched with the travelling wheel and the pin gear, so that the body 200 runs stably.

Preferably, referring to fig. 1 and 2, each pin rack 110 is disposed on a side of the corresponding rail 100 close to the body 200.

The pin rack 110 is relatively weak with respect to the rail 100. The pin and rack structure is arranged on one side of the corresponding track 100 close to the body 200, so that the probability of collision between the pin and rack structure 110 and a foreign object is reduced, and the pin and rack structure 110 can be better protected.

The breaking and cutting driving mechanism 500 may be a power mechanism such as a motor or an internal combustion engine, and may drive the breaking and cutting roller 400 to move through a direct gear transmission, a chain transmission or a belt 510 transmission. The extending direction of the breaking and cutting roller 400 is perpendicular to the track 100, namely the rotating section of the breaking and cutting roller 400 is consistent with the direction of the track 100, when the body 200 moves along the track 100, the breaking and cutting roller 400 rotates to break and clean large coal blocks, wet coal, frozen coal and coal gangue which appear on the screen grate, and the cleaning efficiency is improved.
