Description

Technical Field

[0001] This utility model relates to the field of impact crusher technology, and in particular to a discharge particle size adjustment device for impact crushers. Background Technology

[0002] An impact crusher is a machine used for crushing stone, utilizing the principle of impact crushing to pulverize materials; it is a crushing machine that uses impact energy to break materials. The impact liner is a wear-resistant plate-like structure installed on the impact plate of the impact crusher, typically located on the side of the crushing chamber; when ore enters the crushing chamber and is impacted, the impact liner absorbs the impact force and transmits it to the ore, causing it to crush.

[0003] During the long-term use of impact crushers, the impact liners are constantly subjected to the impact and wear of ore, which can lead to wear, breakage, or deformation. This results in an increased gap between the impact liners and the hammers, affecting the output particle size and product quality. The existing solution is to replace the worn impact liners periodically, which increases costs and wastes resources.

[0004] Therefore, those skilled in the art urgently need to develop a discharge particle size adjustment device for impact crushers. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a discharge particle size adjustment device for impact crushers.

[0021] Please see Figures 1-5 This utility model provides an embodiment: a discharge particle size adjustment device for an impact crusher, comprising a machine body 1, a turntable rotatably mounted inside the machine body 1, a plurality of rotors 2 fixedly mounted circumferentially on the turntable, a plurality of impact plates 3 inside the machine body 1, each impact plate 3 being located outside the rotors 2, and each impact plate 3 having an impact liner 4 on the side near the rotors 2, each impact plate 3 having a support rod 51 extending through it, and both ends of each support rod 51 extending out of the machine body 1, and sliding grooves 6 being formed on both sides of the machine body 1 near each support rod 51, each sliding groove 6 being slidably connected to the corresponding support rod 51, and both ends of each support rod 51 being connected to the support plate 5, and an adjustment component being provided on the outer side of the machine body 1, the adjustment component being used to control each support plate 5 to drive the support rod 51 to slide on the sliding groove 6, thereby adjusting the distance between the impact plate 3 and the rotor 2.

[0022] Furthermore, a cover plate is provided on the outside of the slide 6. After the distance between the impact plate 3 and the rotor 2 is adjusted, the cover plate covers the slide 6 to prevent the material inside the machine body 1 from running out.

[0023] Furthermore, the adjustment assembly includes support columns 8 disposed on both sides of the body 1, each support column 8 is fitted with a sleeve 10, the sleeve 10 is slidably connected to the support column 8, each support plate 5 is slidably disposed with an adjustment plate 7 on the side near the support column 8, each adjustment plate 7 is hinged with a first hinge rod 9 on the side near the support column 8, each first hinge rod 9 is rotatably connected with a first fixing block 13 on the side away from the adjustment plate 7, each first fixing block 13 is fixedly connected to the support column 8, and each sleeve 10 is provided with a locking screw 12.

[0024] By sliding the sleeve 10, the sleeve 10 drives the first hinge rod 9 to rotate; when the sleeve 10 slides towards the machine body 1, the angle between the first hinge rod 9 and the support column 8 decreases, and at the same time, the first hinge rod 9 drives the adjusting plate 7 to slide away from the machine body 1; since the angle between the first hinge rod 9 and the support column 8 decreases, the adjusting plate 7 drives the support plate 5 to move towards the side closer to the support column 8, thereby driving the support rod 51 to move together. The support rod 51 is connected to the counterattack plate 3, thereby controlling the counterattack plate 3 to move towards the rotor 2, thereby adjusting the distance between the counterattack liner 4 and the rotor 2.

[0025] Furthermore, each of the first hinge rods 9 is hinged to a second hinge rod 11 at its middle position, and each of the second hinge rods 11 is rotatably connected to a second fixing block 14 on the side away from the first hinge rod 9, and each second fixing block 14 is fixedly connected to the sleeve 10.

[0026] When the first hinge 9 rotates, the second hinge 11 rotates in the opposite direction, and the second hinge 11 supports and fixes the first hinge 9.

[0027] Furthermore, the support rod 51 on each counter-attack plate 3 is fixedly connected to the corresponding counter-attack plate 3, and two rod sleeves 15 are fitted on each support rod 51. The rod sleeves 15 are fixedly connected to the corresponding support rod 51, and each rod sleeve 15 is slidably connected to the corresponding slide groove 6.

[0028] The support rod 51 is restricted by the sleeve 15, so that the support rod 51 can only move along the direction of the slide groove 6, thereby improving the overall stability.

[0029] The working principle of this utility model is as follows: When in use, the turntable drives the rotor 2 to rotate, and the rotor 2 drives the impact plate 3 to rotate. After the rotor 2 comes into contact with the stone, it will rebound onto the impact liner 4 and reciprocate to crush the stone. When the impact liner 4 is worn, the sliding sleeve 10 slides towards the machine body 1, the angle between the first hinge rod 9 and the support column 8 decreases, the adjusting plate 7 drives the support plate 5 to move towards the side closer to the support column 8, thereby driving the support rod 51 to move together. The support rod 51 is connected to the impact plate 3, thereby controlling the impact plate 3 to move towards the rotor 2, thereby adjusting the distance between the impact liner 4 and the rotor 2. After adjustment, the sliding sleeve 10 is locked and fixed by the locking screw 12.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
