Detailed Description
The invention will be further explained with reference to the drawings.
As shown in fig. 1, the adjustable crushing device for coal comprises a crushing box 11, a crushing device and an adjusting device;
the upper end of the crushing box 11 is provided with a feeding hole 12, and the lower end is provided with a discharging hole 13;
the crushing device comprises a first crushing roller 21 and a second crushing roller 4; the first crushing rollers 21 are a pair and are arranged in the crushing box 11 in a bilaterally symmetrical mode, and the second crushing roller 4 is positioned below the pair of first crushing rollers 21;
the adjusting devices are a pair and are arranged at two sides of the second crushing roller 4 in a bilateral symmetry mode, and each group of adjusting devices comprises an adjusting rod 32, an elastic cloth 33 and a supporting plate 35;
the support plate 35 is horizontally arranged in the crushing box 11, a through hole for blanking is formed in the support plate and is positioned below the second crushing roller 4, the adjusting rod 32 is connected to the crushing box 11 in a threaded mode, a third lining plate 34 is rotatably installed at one end of the adjusting rod, the lower end of the third lining plate 34 is arranged on the support plate 35 in a left-right sliding mode, the upper end of the third lining plate is connected with the inner wall of the crushing box 11 through an elastic cloth 33, and the elastic cloth 33, the third lining plate 34, the support plate 35 and the inner wall of the crushing box 11;
