The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0019] First embodiment:
[0020] See also Figures 1 to 3 ,in Figure 1 1 is a schematic diagram of the disassembled structure of the hammer head of the kiln skin crusher of the first embodiment. Figure 2 is a schematic diagram of the internal structure of the installation cavity in the first embodiment, Figure 3 yes Figure 2 A magnified view of the local structure at A.
[0021] The utility model provides a hammer head of a kiln skin crusher: comprising a hammer body 101, a hammer handle 102 and a connecting mechanism, wherein the connecting mechanism comprises a rotating assembly 103, a rotating shaft 104, a first threaded rod 105, a second threaded rod 106, two ball screw nut pairs 107 and two plug rods 108, and the rotating assembly 103 comprises a rotating disk 109, a rotating shaft 110 and an output gear 111. The above-mentioned solution solves the problem that the hammer heads of existing crushers for crushing kiln skins are often integrally cast, and if the hammer body 101 of the hammer head is severely worn, it needs to be replaced as a whole, resulting in a high replacement cost. It can be understood that the above-mentioned solution can be used on the hammer head structure of a crusher for crushing kiln skins.
[0022] According to this specific embodiment, a hammer shaft hole 112 is provided at one end of the hammer handle 102, and the hammer body 101 is provided at the other end of the hammer handle 102. Both sides of the bottom of the hammer handle 102 are provided with a slot 113, and both sides of the top of the hammer body 101 are provided with a clamping plate 114, and the clamping plate 114 is adapted to the slot 113, and each of the clamping plates 114 is provided with a clamping hole 115. A mounting cavity 116 is provided at the center of the bottom of the hammer handle 102, and the rotating shaft 104 is rotatably connected to the center of the interior of the mounting cavity 116. The first threaded rod 105 and the second threaded rod 106 are respectively provided at both ends of the rotating shaft 104, the thread of the first threaded rod 105 is opposite to the thread of the second threaded rod 106, the first threaded rod 105 and the second threaded rod 106 are both provided with the ball screw nut pair 107, each of the ball screw nut pairs 107 is provided with the insertion rod 108, and the insertion rod 108 is adapted to the clamping hole 115, and the side surface of the bottom of the hammer handle 102 is also rotatably connected to the rotating assembly 103, and the center of the rotating shaft 104 A transmission gear 117 is provided at the end of the rotating assembly 103 located inside the installation cavity 116, and the transmission gear 117 is mechanically transmitted to the rotating assembly 103. When installing the hammer body 101, after the clamping plate 114 is inserted into the clamping groove 113, the rotating assembly 103 is rotated, and the rotating shaft 104 is driven to rotate inside the installation cavity 116 through the transmission gear 117. Since the first threaded rod 105 and the second threaded rod 106 with opposite threads are respectively provided at both ends of the rotating shaft 104, the two ball screws are driven to rotate. The female pair 107 moves in a direction away from the rotating shaft 104, so that the insertion rod 108 is inserted into the clamping hole 115, thereby completing the installation of the hammer body 101. When the hammer body 101 needs to be removed, the rotating member is rotated, and the rotating shaft 104 is driven to reset by the transmission gear 117, so that the insertion rod 108 is disengaged from the clamping hole 115, so that the hammer body 101 is removed from the bottom of the hammer handle 102. With the above structure, when the hammer body 101 is severely worn, there is no need to replace the entire hammer head, thereby reducing the replacement cost.
[0023] Among them, the side surface of the bottom of the hammer handle 102 is rotatably connected with the rotating shaft 110, and the rotating disk 109 is provided at one end of the rotating shaft 110 located outside the hammer handle 102, and the output gear 111 is provided at one end of the rotating shaft 110 located inside the hammer handle 102. The output gear 111 is meshed with the transmission gear 117. The rotating disk 109 is rotated to drive the output gear 111 to rotate through the rotating shaft 110. Since the output gear 111 is meshed with the transmission gear 117, the rotating shaft 104 is driven to rotate inside the mounting cavity 116.
[0024] Secondly, two limiting rings 118 are arranged on the outer wall of the rotating shaft 110, and the two limiting rings 118 are respectively located on the inner and outer sides of the mounting cavity 116. Through the arrangement of the two limiting rings 118, the structure of the rotating shaft 110 is more stable when it rotates on the side wall of the hammer handle 102.
[0025] At the same time, anti-skid patterns 119 are arranged on the outer side wall of the rotating disk 109 . The anti-skid patterns 119 make it more convenient to rotate the rotating disk 109 .
[0026] When using the hammer head of a kiln skin crusher of this embodiment, when installing the hammer body 101, after inserting the clamping plate 114 into the clamping slot 113, the rotating disk 109 is rotated, and the output gear 111 is driven to rotate through the rotating shaft 110. Since the output gear 111 is meshed with the transmission gear 117, the rotating shaft 104 is driven to rotate inside the installation cavity 116. Since the first threaded rod 105 and the second threaded rod 106 with opposite threads are respectively provided at both ends of the rotating shaft 104, the two ball screws are driven to rotate. The lever nut pair 107 moves in the direction away from the rotating shaft 104, so that the insertion rod 108 is inserted into the clamping hole 115, thereby completing the installation of the hammer body 101. When the hammer body 101 needs to be removed, the rotating part is rotated, and the rotating shaft 104 is driven to reset by the transmission gear 117, so that the insertion rod 108 is disengaged from the clamping hole 115, thereby removing the hammer body 101 from the bottom of the hammer handle 102. With the above structure, when the hammer body 101 is severely worn, there is no need to replace the entire hammer head, thereby reducing replacement costs.
[0027] Second embodiment:
