Description

Technical Field

[0001] The utility model relates to the field of reversible crusher hammers, in particular to a reversible crusher hammer. Background Art

[0002] As the main equipment for mining, crusher equipment is mainly used to crush stones of different sizes. You can choose multiple models of crushers according to the requirements of the discharge. The stone falls directly from the upper part of the machine into the high-speed rotating hammer head. Under the action of high-speed centrifugal force, it hits, rubs and crushes with the hammer head. In the process of hitting and crushing, it collides with the flying stones around the hammer head in an umbrella-shaped manner, and produces high-speed collision and high-density crushing. After hitting each other, the stones are discharged directly from the bottom, forming a closed circuit with multiple cycles, and the screening equipment controls them to reach the required particle size.

[0003] Reversible hammer crusher is a kind of crusher which is widely used at present. The hammer heads of existing reversible hammer crushers are mostly one-piece cast hammer heads. When the speed of the crusher is constant, the impact force of this kind of hammer head on the stone cannot be changed. However, in the actual process, we need to adjust the impact force of the crusher in time for stones of different materials. The impact force caused by the hammer head can be adjusted by changing the weight of the hammer head when its speed is constant. Utility Model Content

[0006] A protrusion is provided inside the mounting groove, a groove is provided on the outside of the weight-increasing piece, the protrusion and the groove correspond to each other, a slot is provided inside the main hammer body, one end of the inner side of the slot is fixedly connected with a spring, the other end of the spring is fixedly connected with a limiting plate, the other end of the limiting plate penetrates outward and is fixedly connected with the protrusion, sliding grooves are provided at both ends of the inner side of the slot, and sliders are fixedly connected at both ends of the limiting plate, and the slider is slidably connected to the inside of the sliding groove.

[0007] As a further description of the above technical solution: a crushing zone is arranged on the outer side of the main hammer body, and a crushing zone is correspondingly arranged at one end of the crushing zone.

[0008] The utility model has the following beneficial effects:

[0009] 1. Compared with the prior art, the hammer head of this reversible crusher can adjust the weight of the weight-adding piece in the installation groove according to different stones to adjust the overall weight of the hammer head, thereby adjusting the impact force of the hammer head on the stone to crush stones of different materials and different particles, and fixation is achieved through the clamping connection between the protrusion and the groove. This fixing method is conducive to the quick disassembly and installation of the weight-adding block.

[0018] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0019] Reference Figure 1-4The utility model provides an embodiment: a reversible crusher hammer head, including a main hammer body 3, the upper end of the main hammer body 3 is fixedly connected to a hammer handle 2, the inside of the hammer handle 2 is provided with a mounting hole 1, the main hammer body 3 can be installed on the drive shaft by setting the mounting hole 1, so that it can perform a rotating crushing operation, the main hammer body 3 is provided with a mounting groove 5, the inside of the mounting groove 5 is correspondingly provided with a weight-increasing member 8, and the mounting groove 5 can correspond to the weight-increasing member 8 by setting the mounting groove 5;

[0020] A protrusion 6 is provided inside the installation groove 5, and a groove 7 is provided on the outside of the weight-increasing member 8. The protrusion 6 and the groove 7 correspond to each other. A slot 4 is provided inside the main hammer body 3. One end of the inner side of the slot 4 is fixedly connected to a spring 9. The other end of the spring 9 is fixedly connected to a limiting plate 12. The other end of the limiting plate 12 penetrates outward and is fixedly connected to the protrusion 6. Pulling the limiting plate 12 inward can drive the protrusion 6 to retract inward. At this time, the weight-increasing member 8 is installed inside the installation groove 5, and the groove 7 corresponds to the protrusion 6. Then, the limiting plate 12 is loosened. Under the action of the spring 9, the protrusion 6 can be reset, so that it can be clamped with the groove 7. This fixing method is helpful for quickly disassembling and installing the weight-increasing block 8, thereby adjusting the impact force of the hammer head on the crusher.

[0021] Slide grooves 10 are provided at both ends of the inner side of the slot 4, and sliders 11 are fixedly connected to both ends of the limit plate 12.
