Technical Field

[0001] The utility model relates to the technical field of hammer crushers, in particular to an anti-wear composite hammer head for hammer crushers. Background Art

[0002] Hammer crushers primarily rely on high-speed rotating hammers to impact materials. The core component of a hammer crusher is the hammer. After entering the crusher, materials are impacted by the high-speed rotating hammers, causing them to break. The crushed materials gain kinetic energy from the hammers, driving them toward the baffles and screen bars within the crusher. Simultaneously, the materials collide with each other, undergoing multiple crushing cycles.

[0003] Patent publication number "CN211487935U" discloses an "anti-wear composite hammer head for a hammer crusher" that includes a hammer body and a hammer handle. The center of the lower end of the hammer handle has an 8-shaped process through hole, and a barb is provided on both side walls of the hammer handle on both sides of the process through hole. The hammer body is made of high-carbon chromium iron, and the hammer handle is made of carbon steel. The hammer body and the hammer handle are connected together by pouring through a negative pressure solid casting process.

[0004] The device extends its service life by connecting the hammer body and the hammer handle together through a negative pressure solid casting process. However, the device will still be damaged, and the damaged part cannot be conveniently replaced after damage, resulting in increased cost of use and waste of resources. In addition, the friction of the hammer head of the device is low, and the stone cannot be crushed more effectively, affecting the stone crushing efficiency of the device.

[0005] Therefore, the utility model provides an anti-wear composite hammer head for a hammer crusher to solve the above problems. Utility Model Content

[0021] The utility model provides a wear-resistant composite hammer head for a hammer crusher. Compared with the prior art, it has the following advantages:

[0022] 1. The wear-resistant composite hammer head used in the hammer crusher is manufactured by placing the hammer handle into the reinforcement cylinder and then placing the screw hole above the screw column. The hammer handle and the screw hole are completely tightened by rotating the cross bar. The screw cover is then screwed to the thread and installed on the crusher. This device avoids the cost increase and resource waste caused by the inability to replace parts due to component damage. The easy-to-replace hammer head design can reduce downtime and quickly resume production, thereby improving overall production efficiency. The easy-to-replace design can reduce maintenance costs because the replacement process is faster and simpler.

[0023] 2. The wear-resistant composite hammer head used in the hammer crusher has circular grooves on the side surface of the hammer head, so that the contact surface between the hammer head and the stone is rougher when the device is crushing the stone, avoiding the hammer head surface being too smooth, which may reduce the friction with the material, making the material difficult to be grasped and crushed during the crushing process, thereby reducing the crushing efficiency. The rough hammer head surface may increase the friction with the material to a certain extent, which helps to better grasp and crush the material. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present application will be further described in detail below through the accompanying drawings and examples.

[0032] Reference Figures 1 to 4 The embodiment of the present application provides an anti-wear composite hammer head for a hammer crusher, including a connection assembly 1 for installation. The connection assembly 1 includes a hammer handle 102, a reinforcement tube 101 movably connected to the side surface of the hammer handle 102, a square hole 106 defined on the underside of the reinforcement tube 101, a rotating rod 108 fixedly connected to the inner wall of the square hole 106, a friction plate 107 rotatably connected to the side surface of the rotating rod 108, and a ramp plate 109 fixedly connected to the inner side of the friction plate 107. The top side surface of the reinforcement tube 101 defines a thread 110, a screw cap 111 screwed to the side surface of the thread 110, and a mounting ring 112 fixedly connected to the upper surface of the screw cap 111.

[0033] In this embodiment, when the hammer handle 102 is inserted from the inside of the reinforcement tube 101, the hammer handle 102 will squeeze the ramp plate 109 to be vertical, causing the friction plate 107 to flip outward from the reinforcement tube 101, thereby increasing the friction between the hammer handle 102 and the reinforcement tube 101 and making the two more secure.

[0034] Reference Figures 1 to 4 In one aspect of this embodiment, there are two friction plates 107, two ramp plates 109, and two rotating rods 108, each positioned correspondingly. The inclined surfaces of the two ramp plates 109 face the inside of the reinforcement tube 101. A recess 103 is defined at the top of the hammer handle 102, with a crossbar 104 fixedly connected to the inner wall of the recess 103. A screw hole 105 is defined at the bottom of the hammer handle 102.

[0035] In this embodiment, after the hammer handle 102 is placed in the reinforcement tube 101 and the screw hole 105 is placed above the screw column 203, the hammer handle 102 and the screw hole 105 are completely tightened by rotating the cross bar 104, and then the screw cover 111 and the thread 110 are screwed together and installed on the crusher. This allows the device to avoid the increase in cost and waste of resources caused by the inability to replace parts due to damaged components. The hammer head design that is easy to replace can reduce downtime and quickly resume production, thereby improving overall production efficiency.
