Description

Technical Field

[0001] The utility model relates to the technical field of hammer crushers, in particular to a cleaning device for a hammer crusher and the hammer crusher. Background Art

[0002] The traditional hammer crusher consists of a feed port, a crushing chamber, a rotor and hammer assembly, a screen plate, and a discharge port. Its working principle is that the rotor and hammer head impact, hit, shear, and crush the material poured into the crushing chamber through high-speed rotation, and the material passing through the screen plate is discharged from the discharge port to complete the primary crushing process. In the field of coal and mineral sampling, when the poured material has high viscosity and high moisture content, the crushing chamber is close to the feed port, and a large amount of sample will adhere to the impact surface of the material, and excessive accumulation will block the feed port.

[0003] In the prior art, a cleaning rod is provided in front of the material receiving disc, and a gap of a certain width is left between the cleaning rod and the material receiving disc. The cleaning rod can scrape the coal sample adhered to the front side of the material receiving disc (i.e., the material receiving surface) and drop it into the crushing chamber. However, relative rotational motion is required between the cleaning rod and the front side of the material receiving disc to scrape off the coal sample adhered to the material receiving disc. The cleaning rod is semicircular or triangular in shape, and the surface of the cleaning rod relative to the material receiving disc is parallel to the front side of the material receiving disc. The contact surface with the coal sample is large, and a wedge-shaped structure is easily formed during the process of scraping the coal sample. The scraper resistance is extremely large, and the larger the contact area, the greater the scraping resistance, which causes the automatic cleaning device to get stuck or trip.

[0035] like Figures 1 to 6 As shown, the utility model provides a cleaning device for a hammer crusher, which is installed on the hammer crusher to facilitate the removal of adhered materials on one side of the material receiving surface at the feed inlet 10 of the hammer crusher; the cleaning device for the hammer crusher comprises a mounting seat 1, a material receiving plate 2, a driving assembly 3, a blocking member 4 and an elastic member 5; the first end of the material receiving plate 2 is hinged to the mounting seat 1; the blocking member 4 is arranged on the mounting seat 1, and the material receiving plate 2 abuts against the blocking member 4; the output end of the driving assembly 3 can abut against or move away from the material receiving plate 2, and when the driving assembly 3 abuts against the material receiving plate 2, the second end of the material receiving plate 2 can rotate with the first end of the material receiving plate 2 as the axis, so that the second end of the material receiving plate 2 moves away from the blocking member 4; the first end of the elastic member 5 is connected to the material receiving plate 2, and the second end of the elastic member 5 is connected to the blocking member 4 or the mounting seat 1, so that the material receiving plate 2 maintains a tendency to abut against the blocking member 4.

[0036] With the above structure, after the cleaning device for the hammer crusher is installed on the hammer crusher, the side of the material receiving plate 2 facing away from the blocking member 4 is used as the material receiving surface. When the material is adhered to the material, the output end of the driving component 3 presses against the second end of the material receiving plate 2 and moves away from the blocking member 4, during which the elastic member 5 is stretched; then the output end of the driving component 3 moves away from the material receiving plate 2, and at this time, the material receiving plate 2 moves toward the blocking member 4 under the action of the restoring force of the elastic member 5, so that the material adhered to the material receiving plate 2 is detached under the action of the reciprocating movement of the material receiving plate 2 and the impact vibration between the material receiving plate 2 and the blocking member 4, making cleaning more convenient; in addition, this method does not set a cleaning component on the side of the material receiving plate 2 that receives the material, which can avoid blockage and tripping.
