DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The following is combined with Figure 1-5 To further explain this application in detail,

[0023] The present application embodiment discloses a combined hammer head for a hammer crusher. Figure 1-5 A combined hammer head of a hammer crusher includes a hammer body 1, the hammer body 1 includes a hammer head 101, a handle body 102 is installed on the top of the hammer head 101, a fixing mechanism 2 is installed in the inner cavity of the handle body 102, and locking mechanisms 3 are installed on both sides of the fixing mechanism 2;

[0024] The fixing mechanism 2 includes a base 201 and a tension spring 208. The base 201 is fixedly connected to the top of the hammer head 101. The top of the base 201 is fixedly connected to a fixing column 202. The top of the fixing column 202 is fixedly connected to a sliding column 204. The surface of the sliding column 204 is slidably connected to a movable disk 203. The top of the sliding column 204 is fixedly connected to a chuck 205. One end of the tension spring 208 is fixedly connected to the top of the inner cavity of the base 201. The bottom of the tension spring 208 is movably connected to a movable ring 206. The chuck 205 is slidably connected to the inner cavity of the movable ring 206.

[0025] Reference Figure 5The locking mechanism 3 includes a movable box 305, the inner cavity of the movable box 305 is movably connected with a triangular block 307, the triangular block 307 is clamped at the bottom of the chuck 205, one side of the triangular block 307 is fixedly connected with a spring 306, the other end of the spring 306 is fixedly connected with a positioning plate 304, the positioning plate 304 is fixedly connected to one side of the movable box 305, through the setting of the triangular block 307, the chuck 205 and the movable disk 203 are effectively clamped, the hammer head 101 can be stably fixed to the bottom of the handle body 102 to avoid falling off when crushing materials, and through the setting of the spring 306, when the triangular block 307 is subjected to pressure, the spring 306 is deformed, and when the triangular block 307 is free of pressure, the spring 306 quickly restores the triangular block 307 to its initial position;

[0026] Reference Figure 1 and Figure 5 The cam 304 is provided with a plurality of grooves 306 on both sides of the hammer head 101, and a cylinder 302 is fixedly connected to one side of the positioning plate 304. The cylinder 302 is movably connected to the inner wall of the groove 4. The surface of the cylinder 302 is fixedly connected to the limit block 303. The setting of the groove 4 plays a guiding role for the cylinder 302, so that the cylinder 302 can slide stably inside the groove 4 to prevent the cylinder 302 from being restricted by the groove 4. The setting of the cylinder 302 can drive the triangular block 307 and the movable ring 206 to move up and down, thereby avoiding the effect of being unable to transmit due to the lack of parts, and then being unable to achieve the effect of rapid installation and disassembly. The position of the spring 306 is fixed by the setting of the positioning plate 304. Finally, the setting of the limit block 303 limits the cylinder 302 to prevent the cylinder 302 from falling off from the inner cavity of the handle body 102, and at the same time plays a guiding role, making the movement of the triangular block 307 more stable.

[0027] Reference Figure 5 The inner cavity of the cylinder 302 is fixedly connected with a pull ring 301, and the pull ring 301 is in the shape of a ring. The setting of the pull ring 301 provides a fulcrum for the operator. The hammer head 101 and the handle body 102 can be disassembled by simply pulling the pull ring 301, making the disassembly and assembly more convenient;

[0028] Reference Figure 3 The bottom of the tension spring 208 is fixedly connected to the limiting plate 207, the limiting plate 207 is movably connected to the inner cavity of the hammer head 101, the bottom of the limiting plate 207 is fixedly connected to the top of the movable ring 206, and the movable ring 206 is movably connected to the inner cavity of the handle body 102. The setting of the limiting plate 207 has a stable connection effect on the connection between the tension spring 208 and the movable ring 206, avoiding unstable connection between the movable ring 206 and the tension spring 208;

[0029] Reference Figure 4The edge of the bottom of the movable disk 203 is set with a bevel, and the edge of the top of the chuck 205 is set with a bevel. Through the setting of the bevel on the top of the chuck 205, the bottom of the triangular block 307 can move toward the inside of the movable box 305 while contacting the chuck 205, avoiding the triangular block 307 being stuck on the top of the chuck 205 and being unable to be fixed. Through the bevel setting at the bottom of the movable disk 203, when the triangular block 307 drives the movable disk 203 to move, after the top is subjected to pressure, the triangular block 307 will shrink to the inside of the movable box 305, thereby achieving the effect of separating the hammer head 101 and the handle body 102.

[0030] Working principle: When installation is required, the base 201, the fixed column 202, the movable disk 203, the sliding column 204 and the chuck 205 are inserted into the inner cavity of the handle body 102. When the triangular block 307 contacts the chuck 205, the triangular block 307 begins to move into the movable box 305 under the extrusion force. The movement of the triangular block 307 causes the spring 306 to deform. When the triangular block 307 is completely moved into the movable box 305, the hammer head 101 is pushed upward. When the chuck 205 does not contact the triangular block 307, the hammer head 101 is pushed upward. After the corner block 307 is released, the spring 306 recovers its deformation and firmly clamps the chuck 205 through the triangular block 307. When it needs to be removed, the pull ring 301 is pulled downward, and the movement of the pull ring 301 drives the cylinder 302 to move, and the movement of the cylinder 302 drives the limit block 303 to move downward, and the movement of the limit block 303 drives the positioning plate 304 and the movable box 305 to move, and the movement of the movable box 305 drives the limit plate 207 and the movable ring 206 to move downward, at this time, the tension spring 208 is deformed, and the movable box 305 is in the state of being moved downward. The movement of 05 drives the spring 306 and the triangular block 307 to move until the triangular block 307 contacts the movable disk 203. The triangular block 307 is subjected to pressure, causing the spring 306 to deform and continue to move downward until the triangular block 307 does not contact the movable disk 203. The spring 306 recovers its deformation and pushes the triangular block 307 to move. Then the triangular block 307 is snapped to the bottom of the movable disk 203, and then the handle body 102 is pulled upward. The movement of the handle body 102 drives the triangular block 307 upward. The movement of the triangular block 307 drives the movable disk 203 to move upward until the top of the movable disk 203 contacts the bottom of the chuck 205, and the triangular block 307 is subjected to pressure again, causing the spring 306 to deform, until the triangular block 307 passes through the movable disk 203 and the chuck 205, and the spring 306 recovers its deformation, and finally the triangular block 307 returns to its original position. At the same time, the tension spring 208 recovers its deformation, so that all the following structures return to their original positions, and the hammer head 101 can be replaced at this time.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
