Description

Technical Field

[0001] This utility model relates to the field of crushing machinery technology, specifically to an easily replaceable hammer assembly for a vertical crusher. Background Technology

[0002] During the crushing process, the stone falls from the feed hopper onto the throwing disc. After being impacted by the high-speed rotating throwing disc ribs, the material is thrown at high speed towards the cylinder liner and impacted by centrifugal force, achieving the first stage of crushing. The crushed material falls and is subjected to the impact, grinding, and squeezing action of multiple layers of hammers with different gaps, eventually reaching the finished product and being discharged from the crushing chamber. In this crushing process, the material is crushed and ground within the crushing chamber formed by the cylinder liner and hammers. As the main crushing part of the crusher, the hammers wear out the fastest. If the worn hammers are not replaced in time, the output particle size will not meet the standards, and the production capacity will be reduced. If the hammer design is unreasonable, the material may also cause wear to the rotor body during the crushing process. The existing crushing structure of most crushers adopts a one-piece molding structure, and the whole structure must be replaced when replacing parts, which is time-consuming, labor-intensive, and increases the operating cost.

[0017] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures and features in one embodiment may be advantageously incorporated into other embodiments.

[0018] To more clearly describe an easily replaceable hammer assembly for a vertical crusher, combined with the attached... Figure 1-4 Detailed description is as follows: like Figure 1-4 As shown, a replaceable hammer assembly for a vertical crusher includes a hammer 1, an adjusting base plate 2, and a base plate mounting plate 7. The base plate mounting plate 7 is fixed on the rotor body. The base plate mounting plate 7 has a U-shaped through hole that penetrates the base plate mounting plate 7 and is used to install bolts 5. The bolts 5 can move along the length of the U-shaped through hole to achieve position adjustment within the range of the U-shaped through hole. A limiting groove is provided on one side of the base plate mounting plate 7. The limiting groove intersects the U-shaped through hole perpendicularly, and the lower end of the U-shaped through hole is located in the limiting groove.

[0019] Furthermore, the adjusting seat plate 2 is installed on the side of the seat plate mounting plate 7 that has a limiting groove. The adjusting seat plate 2 has a positioning groove on the side close to the seat plate mounting plate 7. The positioning groove has a trapezoidal cross-section and a through hole. The adjusting seat plate 2 has a groove on the side away from the seat plate mounting plate 7.

[0020] Furthermore, an adjustment part is provided between the adjusting base plate 2 and the base plate mounting plate 7. The adjustment part includes a positioning block 4 and several adjusting pads 3. The positioning block 4 has a circular through hole, and the lower part of the positioning block 4 has a trapezoidal structure. The lower trapezoidal structure of the positioning block 4 is adapted to the positioning groove of the adjusting base plate 2. During assembly, the lower trapezoidal structure of the positioning block 4 is embedded in the positioning groove, and the circular through hole on the positioning block 4 is coaxially aligned with the through hole on the adjusting base plate 2. The several adjusting pads 3 are respectively located in the positioning... On both sides of block 4, the upper part of the positioning block 4 and the adjusting pads 3 on both sides are located in the limiting groove of the seat plate mounting plate 7 and are adapted to the limiting groove. The bolt 5 passes through the through hole of the adjusting seat plate 2, the circular through hole of the positioning block 4 and the U-shaped through hole of the seat plate mounting plate 7, and firmly fixes the adjusting seat plate 2, the adjusting pads 3 and the positioning block 4 on the seat plate mounting plate 7. By adjusting the installation position of the adjusting pads 3 on both sides of the positioning block 4, the positioning block 4 can be moved left and right, thereby driving the adjusting seat plate 2 to move left and right synchronously.

[0021] Furthermore, in this embodiment, there are two hammerheads 1, which are symmetrically installed on the side of the adjusting base plate 2 away from the base plate mounting plate 7. The hammerheads 1 are fixed to the adjusting base plate 2 by screws. The screws are countersunk to prevent damage to the screws when crushing materials. A protrusion is provided on the side of the hammerhead 1 near the adjusting base plate 2. The protrusion is adapted to the groove of the adjusting base plate 2. The protrusion is located in the groove of the adjusting base plate 2, and one side of the protrusion is connected to the side of the groove by a snap-fit ​​method, thereby enhancing the connection strength between the hammerhead 1 and the adjusting base plate 2.

[0022] Furthermore, the hammerhead 1 is equipped with a high-hardness impact-resistant alloy block 6, which is located at the impact leading edge of the hammerhead 1. When the two hammerheads 1 are fixed on the adjusting seat plate 2, the high-hardness impact-resistant alloy blocks 6 on the two hammerheads 1 face the rotor body and the impact plate 8 respectively. When the position of the adjusting seat plate 2 is adjusted by the above-mentioned adjusting part, the hammerhead 1 is driven to move closer to or away from the impact plate 8 to adjust the gap between the hammerhead 1 and the impact plate 8, thereby adapting to the crushing requirements of different materials. When the hammerhead assembly is worn, the adjusting seat plate 2 or the hammerhead 1 can be replaced according to the actual situation. The hammerhead 1 is equipped with a high-hardness impact-resistant alloy block 6, which has the characteristics of strong impact resistance, small size, and easy replacement. The adjusting seat plate 2 can not only adjust the gap between the hammerhead 1 and the impact plate 8, but also protect the rotor body and prevent the crushed material from directly damaging the rotor body.

[0023] The parts not described in detail in this embodiment are existing technologies.

[0024] It should be noted that although the present invention has been described through the above embodiments, the present invention may have other various embodiments. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and modifications to the present invention, but these changes and modifications should all fall within the scope of protection of the appended claims and their equivalents.
