Description
Technical Field
[0001] The utility model relates to the technical field of raw coal transportation systems, and specifically refers to a multifunctional raw coal transportation system. Background Art
[0002] During the transportation of raw coal, large pieces of coal gangue or sundries such as ironware frequently cause the belt conveyor to stop, seriously affecting the safe transportation of raw coal, restricting the automation level of raw coal transportation, and at the same time increasing the labor intensity and working hours of workers.
[0003] Specifically, during the transportation of raw coal from the coal mining face, large pieces of coal gangue, support bolts, etc. will be generated at the working face and transported through the belt conveyor in the roadway. The large pieces of coal gangue and support bolts will touch the protection of the belt conveyor, such as deviation prevention, emergency stop by pulling the wire, coal stacking, etc.; or cause blockage at the feeding point. If not stopped and disposed of in time, it will damage the belt, and seriously cause the belt to tear or break, restricting the safe operation of the belt conveyor.
[0004] In order to avoid the occurrence of phenomena such as large pieces of coal gangue and support bolts touching the protection of the belt conveyor, a multifunctional raw coal transportation system is urgently needed to be studied. Content of the Utility Model
[0005] To solve the above technical problems, the technical solution provided by the utility model is: a multifunctional raw coal transportation system, including a belt conveyor, an inclined sieve is arranged at the discharging end of the belt conveyor, a crusher is correspondingly arranged below the sieve, a coal bunker is arranged below the discharging end of the crusher, the sieve is correspondingly installed above the coal bunker, a belt self-unloading iron remover is arranged at the top of the belt conveyor, the belt self-unloading iron remover is used for fixedly installing on the roadway roof, the running direction of the belt of the belt self-unloading iron remover is the same as or the included angle with the transportation direction of the belt conveyor is less than 90°, and the support bolts and other ironware in the raw coal are sucked out and transported away by the belt self-unloading iron remover, and the ironware is transferred away through the cross-heading transportation.
[0006] Further, a discharging roller is arranged at the discharging end of the belt conveyor to facilitate the discharge of the coal of the belt conveyor into the sieve.
[0007] Further, the sieve is inclined with the left end lower and the right end higher, and both ends of the sieve are fixed on the fixed plate in the roadway through fixed rods, and rubber shock-absorbing springs are installed at both ends of the fixed rods extending out of the fixed plate.
[0008] The advantages of the utility model compared with the prior art are as follows:
[0009] The utility model is provided with a belt self-unloading iron remover at the top of the belt conveyor. The belt self-unloading iron remover is used for being fixedly installed on the roadway roof. The running direction of the belt of the belt self-unloading iron remover is the same as or the included angle with the transportation direction of the belt conveyor is less than 90°. Through the belt self-unloading iron remover, ironware such as support bolts in raw coal can be timely sucked out and transported away, and the ironware is transported away through the crossheading transportation, avoiding damage to the belt when the ironware such as support bolts is sucked out.
[0010] The utility model installs a sieve and a crusher at the upper opening of the coal bunker. Large coal gangues are screened out by the sieve and then enter the coal bunker after being crushed by the crusher, avoiding the event of triggering the protection of the belt conveyor during the subsequent transportation process of the belt conveyor for large coal gangues.
[0011] The utility model adds an iron remover at the source and adds a sieve and a crusher at the upper opening of the coal bunker. Through the comprehensive treatment of large coal gangues and ironware, the influence of sundries such as large coal gangues and ironware on the raw coal transportation system is eliminated, ensuring the safe operation of the raw coal transportation system, reducing the manual input, improving the automation level of the raw coal transportation system, reducing the failure rate of the raw coal transportation, ensuring the safe and efficient operation of the raw coal transportation, and meeting the raw coal transportation requirements.

[0016] The utility model is introduced in detail in conjunction with the drawings.
[0017] When the utility model is specifically implemented, a multifunctional raw coal transportation system is provided, including a belt conveyor 1. An inclined sieve 2 is arranged at the discharging end of the belt conveyor 1. A crusher 3 is correspondingly arranged below the sieve 2. A coal bunker 4 is arranged below the discharging end of the crusher 3. The sieve 2 is correspondingly installed above the coal bunker 4. A belt self-unloading iron remover 5 is arranged at the top end of the belt conveyor 1. The belt self-unloading iron remover 5 is used for fixed installation on the roadway roof. The running direction of the belt of the belt self-unloading iron remover 5 is the same as or the included angle with the transportation direction of the belt conveyor 1 is less than 90°. The belt self-unloading iron remover 5 sucks out and transports ironware such as support bolts in the raw coal, and transports the ironware away through the cross-heading transportation.
[0018] Embodiment:
[0019] When the utility model is in use, at the position of the belt conveyor 1 roadway close to the cross-heading, a belt self-unloading iron remover 5 is installed above the belt conveyor 1 (fixed on the roadway roof and installed avoiding the sieve 2). The running direction of the lower part of the belt in the belt self-unloading iron remover 5 is the same as or the included angle with the transportation direction of the belt conveyor 1 is less than 90°, which is convenient for sucking out and transporting ironware such as support bolts in the raw coal, and transporting sundries such as ironware away through the cross-heading transportation. At the same time, it avoids damaging the belt when sucking out support bolts and other ironware. At the upper opening of the coal bunker, a sieve 2 and a crusher 3 are installed. Large coal gangue on the belt conveyor 1 is screened out by the sieve 2 and then enters the coal bunker 4 after being crushed by the crusher 3, avoiding the occurrence of events that trigger the protection of the belt conveyor during the subsequent transportation of the belt conveyor 1. Through the above structural settings, it is possible to avoid the occurrence of phenomena such as large coal gangue and support bolts touching the belt conveyor protection, ensuring the normal operation of the belt conveyor.
[0020] In order to facilitate the discharging of the belt conveyor, a discharging roller 6 is arranged at the discharging end of the belt conveyor 1, so as to facilitate discharging the coal of the belt conveyor 1 into the sieve 2.
[0021] In order to facilitate the screening out of large coal gangue by the sieve, the sieve 2 is inclined with the left end lower and the right end higher. Both ends of the sieve 2 are fixed on the inner fixing plate 8 of the roadway through fixing rods 7. Rubber shock-absorbing springs 9 are installed at both ends of the fixing rods 7 extending out of the fixing plate 8. The rubber shock-absorbing springs can play a shock-absorbing effect during the process of the sieve screening large coal gangue.
[0022] In order to facilitate the height adjustment of the sieve adaptation, a group of fixing rods 7 are rotatably connected to the bottom end of the sieve 2, and a group of fixing plates 7 are rotatably connected to the top end of the sieve 2.
[0023] In order to facilitate the coal to enter the coal bunker, a coal inlet 10 is arranged at the top end of the coal bunker 4, so as to facilitate the coal after being crushed by the crusher 3 to enter the coal bunker 4 from the inlet 10.
[0024] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and without departing from the gist of the creation of the present utility model, without creative design, they create structural manners and embodiments similar to the technical solution, all of which shall fall within the protection scope of the present utility model.
