Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5As shown, the utility model provides a spiral drum of a coal mining machine, comprising a spiral drum 1, a mounting shell 2 is fixedly connected to the outer side of the spiral drum 1, a mounting block 6 is movably sleeved in the inner cavity of the mounting shell 2, a threaded rod 3 is threadedly connected to the middle part of the mounting shell 2, a threaded ring 5 is fixedly connected to the side of the mounting shell 2 away from the mounting block 6, a coal mining cutting head 7 is fixedly connected to the side of the mounting block 6 away from the spiral drum 1, and a rotating plate 4 is fixedly connected to the side of the threaded rod 3 away from the threaded ring 5;

[0021] The spiral drum 1 drives the coal cutting head 7 to rotate and contact with the coal, so as to mine the coal. When a coal cutting head 7 is damaged during long-term use, the rotating plate 4 is rotated to drive the threaded rod 3 to rotate. The threaded rod 3 rotates to move to the outside of the mounting shell 2, so that the threaded rod 3 is pulled out from the inner cavity of the through hole 8, and the mounting block 6 is pulled out from the inner cavity of the mounting shell 2 to replace the coal cutting head 7. When a single coal cutting head 7 is damaged, it is no longer necessary to replace the spiral drum 1 as a whole, but only a single replacement is required, which is quick and convenient.

[0022] A protective sleeve 9 is adhered to the outer side of the spiral drum 1, a reinforcing rod 10 is fixedly connected to the inner cavity of the spiral drum 1, and a leakage groove 11 is opened on the surface of the protective sleeve 9;

[0023] The protective sleeve 9 on the outside of the spiral drum 1 can protect the spiral drum 1, and the reinforcing rod 10 in the inner cavity of the spiral drum 1 can strengthen the supporting strength of the spiral drum 1 to avoid deformation of the spiral drum 1 during long-term use.

[0024] A through hole 8 is formed on one side of the mounting block 6 close to the spiral drum 1, and the threaded rod 3 passes through the through hole 8 and engages with the inner cavity of the threaded ring 5;

[0025] Through the through hole 8 on the side of the mounting block 6 close to the spiral drum 1, the threaded rod 3 can pass through the through hole 8 and engage with the threaded ring 5, so that the threaded rod 3 locks the mounting block 6 to prevent the mounting block 6 from falling out of the inner cavity of the mounting shell 2 due to force during the coal mining process.

[0026] The mounting block 6 is attached to the inner wall of the mounting shell 2, and a cross-shaped groove is provided in the middle of the rotating plate 4;

[0027] The mounting block 6 is fitted to the inner wall of the mounting shell 2 so that the mounting block 6 will not shake in the inner cavity of the mounting shell 2. Through the cross-shaped groove in the middle of the rotating plate 4, the staff can use a tool to rotate the rotating plate 4 to drive the threaded rod 3 to rotate.

[0028] The mounting shell 2 is fixedly connected to the spiral drum 1 through the leakage groove 11, and the leakage groove 11 is in contact with the outer surface of the mounting shell 2;

[0029] The mounting shell 2 is fixedly connected to the spiral drum 1 through the leakage groove 11 , so that the protective sleeve 9 can provide all-round protection to the spiral drum 1 , thereby preventing the spiral drum 1 from being seriously damaged.

[0031] By disposing a plurality of reinforcing rods 10 , the reinforcing rods 10 can strengthen the supporting strength of the spiral drum 1 from different directions, thereby preventing the spiral drum 1 from being deformed due to external forces during use.

[0032] The working principle and use process of the utility model are as follows: the spiral drum 1 is connected to the driving component of the coal mining machine, and then the spiral drum 1 is driven to rotate, and the rotation of the spiral drum 1 drives the coal mining cutting head 7 to operate, so that the coal mining cutting head 7 contacts with the coal to mine the coal;

[0033] When a single coal cutting head 7 is damaged, the rotating plate 4 is rotated to drive the threaded rod 3 to rotate, and the threaded rod 3 is screwed out from the inner cavity of the threaded ring 5 and the through hole 8, so that the mounting block 6 is pulled out from the inner cavity of the mounting shell 2, and then the single coal cutting head 7 is replaced;

[0034] The outside of the spiral drum 1 is protected by the protective sleeve 9 to prevent coal from falling and hitting the outer surface of the spiral drum 1 during mining, thereby damaging the spiral drum 1. The reinforcing rod 10 is used to increase the supporting strength of the spiral drum 1, so that when the spiral drum 1 is hit from the outside, the spiral drum 1 will not be excessively deformed due to the reinforcement of the reinforcing rod 10.
