[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0024] Reference Figure 1-Figure 5 As shown, a hammer head structure of a hammer crusher includes a fixing pin 1, one end of which is fixedly connected to a limit seat 8, the other end of which is provided with a fixing hole 9, the inner thread of which is connected to a fastening bolt 10, and the outer surface of the fixing pin 1 is slidably connected to a plurality of evenly distributed crushing hammer heads 2;

[0025] Among them, the crushing hammer head 2 includes an integrally formed hammer handle 201 and a hammer body 202. The hammer body 202 is fixedly connected to the upper end of the hammer handle 201. The front end of the hammer handle 201 is penetrated by a connecting hole 3 with the same cross-sectional size as the fixing pin 1. The outer surface of the hammer body 202 is provided with a first cutting edge 4, a second cutting edge 5 and a third cutting edge 6 distributed equidistantly from top to bottom. The outer surface of the hammer body 202 is provided with a number of evenly distributed grooves 7.

[0026] Furthermore, the cutting angles of the first cutting edge 4, the second cutting edge 5 and the third cutting edge 6 are 45°, 30° and 60° respectively. By setting the first cutting edge 4, the second cutting edge 5 and the third cutting edge 6 at different angles, flexible crushing capabilities can be provided according to the hardness and properties of different materials, thereby improving the overall crushing efficiency. Different cutting angles can optimize the crushing process under different conditions and increase the adaptability to the material.

[0027] Furthermore, the grooves 7 are diamond-shaped and distributed in an array to form a grid structure. The grid structure formed by the diamond-shaped grooves 7 can increase the friction between the hammer head and the crushed material, enhance the grip, prevent the material from sliding, and improve the crushing effect. At the same time, the evenly distributed grooves 7 help to disperse the impact force on the surface of the hammer head, reduce concentrated wear, and extend the service life of the hammer head.

[0028] Furthermore, the crushing hammer head 2 is made of alloy steel. By manufacturing the hammer head with alloy steel, the wear resistance and impact resistance can be effectively improved, and it can adapt to more severe working environments.

[0029] Furthermore, the outer edges of the first cutting edge 4, the second cutting edge 5 and the third cutting edge 6 are smooth arc edges. The smooth arc edges can reduce the friction between the hammer head and the material, thereby reducing wear and extending the service life of the hammer head.

[0030] Furthermore, the cross-section of the fixing pin 1 is cross-shaped. The cross-shaped design can provide support in multiple directions, which helps to improve the fixing stability of the hammer head and reduce loosening or displacement during operation. At the same time, it can more effectively disperse the impact force acting on the pin, reduce the risk of damage caused by impact, and improve durability.

[0031] The above-mentioned hammer head structure is installed on a hammer breaker, which includes a casing 11. A drive shaft 12 is rotatably connected to the inside of the casing 11. A mounting roller 13 is fixedly connected to the drive shaft 12. A number of evenly distributed limit plates 14 are fixedly connected to the mounting roller 13. Six evenly distributed docking holes 15 are opened at the front end of the limit plate 14. The fixing pin 1 is inserted into the inside of the docking hole 15. The crushing hammer heads 2 are evenly distributed between two adjacent limit plates 14 and are fixed by the fixing pin 1 and the fastening bolt 10.

[0032] Working principle: When in use, align the connecting hole 3 on the hammer handle 201 with the docking hole 15 on the upper end of the limit plate 14, then insert the fixing pin 1 into the docking hole 15 and the connecting hole 3 and install the fastening bolt 10 inside the fixing hole 9, and then install the crushing hammer head 2 on the crusher. When the crusher is running, the driving shaft 12 drives the crushing hammer head 2 to rotate for crushing. When the crushing hammer head 2 contacts the material, the grid structure formed by the diamond-shaped grooves 7 can increase the friction between the hammer head and the crushed material, enhance the grip, and ensure that the material is not easy to slide. At the same time, the first cutting edge 4, the second cutting edge 5 and the third cutting edge 6 at different angles enable the hammer head to contact the material with more cutting surfaces, thereby improving the crushing efficiency.

[0033] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed for the present invention is defined by the appended claims and their equivalents.
