[0016] The following describes the special tool for handling blockage at the discharge bin opening of a coal feeder according to the utility model in conjunction with the accompanying drawings.

[0017] In the first embodiment of the present application, Figure 1 and Figure 2As shown, the special tool for handling blockage at the discharge bin of a coal feeder (hereinafter referred to as "this patent") comprises a frame 1, a pulley 2, an extended pneumatic pick assembly 3, an extended frame 3-1, a pneumatic pick 3-2, a manual winch 4, and a control arm 5. The frame 1 is fixedly mounted on the upper part of the coal feeder hopper, the pulley 2 is hoisted in the middle section of the crossbeam of the frame 1, the manual winch 4 is fixedly mounted on the lower side of the frame 1, the steel wire rope on the manual winch 4 passes through the pulley 2 to be connected to the extended pneumatic pick assembly 3, the extended pneumatic pick assembly 3 comprises an extended frame 3-1 and a pneumatic pick 3-2, the steel wire rope of the manual winch 4 passes through the pulley 2 to be connected to the upper end of the extended frame 3-1, the lower end of the extended frame 3-1 is fixedly connected to the pneumatic pick 3-2; the lower end of the pneumatic pick 3-2 is directly opposite to the discharge bin of the coal feeder.

[0018] The utility model number is CN212702389U, which is a coal feeder feeding device that avoids blockage (hereinafter referred to as "the patent"). The patent itself has a complex structure and needs to be produced directly in the factory. It cannot be used for a large number of existing old-style coal feeders. Due to its complex structure and high cost, it is not conducive to rapid promotion. The patent uses a processing device composed of a frame 1, a pulley 2, an extended pneumatic pick assembly 3 and a manual winch 4. It has a simple structure and is easy to produce. It can process large coal blocks (gangue) while ensuring the safety of personnel, and there is no need to modify existing equipment, which is convenient for large-scale promotion.

[0019] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 3 As shown, the middle surface of the extended frame 3-1 is equipped with a control arm 5 through a universal joint. The control arm 5 is retractable, and the length of the retractable arm is controlled by a screw. The retractable control arm 5 enables the worker to more conveniently aim the extended jackhammer assembly 3 at the large charcoal block (gangue) that needs to be broken, which can further improve work efficiency.

[0020] In order to further optimize the working efficiency of the present application and prevent the wire rope from breaking, the extended pneumatic pick assembly 3 has a safety rope connected to the outside of the coal feeder lower bin. In order to further reduce the production cost, the frame 1 is made of I-beam welding.

[0021] When in use, install the special tool to deal with the blockage of the coal feeder discharge bin, and the equipment can be put into use.

[0022] When the utility model is in use, the specific operations are as follows:

[0023] When the discharge port of the coal feeder is blocked, the hand-cranked manual winch 4 is used to lift the extended pneumatic pick assembly 3 above the bin port, and then the manual winch 4 is cranked in the opposite direction to lower the pneumatic pick 3-2 of the extended pneumatic pick assembly 3 to a position where the pneumatic pick tip can touch the large coal block (gangue). The extended pneumatic pick assembly 3 is aimed at the large coal block (gangue), and the pneumatic pick 3-2 of the extended pneumatic pick assembly 3 is started to break or crush the large coal and gangue blocking the discharge port to deal with the blockage of the discharge port. The crushed coal blocks or gangue fall naturally under the action of gravity, and finally the manual winch 4 can be remotely controlled to lift and remove the extended pneumatic pick assembly 3 for next use.

[0024] In summary, the special tool for handling blockages in the coal feeder discharge bin of the embodiment of the utility model is realized by directly hoisting the lengthened pneumatic pick assembly 3 on the original coal feeder through the frame 1 and the pulley 2, and the large pieces of coal or gangue stuck in the coal feeder discharge bin are crushed by the liftable lengthened pneumatic pick assembly 3. The blockage of the coal feeder discharge bin can be safely handled at a relatively low cost, and the transportation efficiency of the coal flow can be effectively improved.

[0025] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
