Description

Technical Field

[0001] This utility model relates to the field of ejection device technology, specifically to an ejection device for a crusher bowl-shaped tile with balanced force. Background Technology

[0002] Currently, the #2 HP6 cone crusher uses a fine crushing chamber type with a discharge opening of 13mm-30mm. Since its commissioning, after replacing the new liners, the wear of the moving cone liner is mainly concentrated in the waist area, forming a bag-like shape. In the later stages of liner use, the current becomes too high and fluctuates greatly, causing circuit jumping, which in severe cases leads to frame cracking, hindering the long-term safe operation of the equipment. This results in the current liner having a maximum service life of three months. Initially, to restore the worn areas of the liner to their original shape, an ejector device is typically used. The traditional method uses three bolts for ejection, but these three bolts are prone to uneven stress, causing uneven ejection and deformation of the cup-shaped bearing. This gradually increases the assembly gap, affecting the equipment's service life. Therefore, we propose a crusher cup-shaped bearing ejector device with balanced stress distribution. Utility Model Content

[0003] The purpose of this utility model is to provide a crusher bowl-shaped tile ejection device with balanced force distribution. It has the advantages of convenient use and balanced force distribution, and solves the problem that the traditional method of using three bolts for ejection operation is prone to uneven force distribution and ejection deviation, which causes the bowl-shaped tile to deform, the assembly gap to gradually increase, and affects the service life of the equipment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a crusher bowl-shaped tile ejection device with balanced force distribution, comprising:

[0005] A fixed frame, wherein a rotating rod is movably connected to the middle end of the fixed frame via a bearing, a drive gear is fixedly connected to the right end of the outer surface of the rotating rod, and a sleeve screw head is fixedly connected to the left side of the rotating rod;

[0006] A guide inner threaded sleeve, the inner side of which is threaded with an ejector screw, and the right end of the outer surface of the guide inner threaded sleeve is fixedly connected with a driven gear that meshes with a drive gear.

[0007] A positioning cover, wherein a connecting plate is fixedly connected between the inner wall of the positioning cover and the outer end of the fixing frame.

[0008] Preferably, the number of guide inner threaded sleeves is three, and the guide inner threaded sleeves are movable at the outer end of the fixing frame.

[0009] Preferably, a fixing plate is fixedly connected to all four sides of the outer surface of the positioning cover, and the inner surface of the fixing plate is provided with mounting holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes the meshing and linkage between the driving gear and three driven gears to simultaneously extend the ejector screws connected to the internal threads of the three guide inner thread sleeves, enabling the bowl-shaped tile to quickly return to its original shape and avoiding the phenomenon of uneven top tilting due to uneven force.

[0024] Example 1

[0025] Please see Figures 1-4 As shown, this utility model provides a technical solution: a crusher bowl-shaped tile ejection device with balanced force, comprising:

[0026] A fixed frame 1 is provided. A rotating rod 101 is movably connected to the middle end of the fixed frame 1 via a bearing. A drive gear 103 is fixedly connected to the right end of the outer surface of the rotating rod 101. A sleeve screw head 102 is fixedly connected to the left side of the rotating rod 101.

[0027] The inner threaded sleeve 106 is connected to the inner thread of the inner threaded sleeve 106 with an ejector screw 104, and the right end of the outer surface of the inner threaded sleeve 106 is fixedly connected to a driven gear 105 that meshes with the drive gear 103.

[0028] The positioning cover 3 has a connecting plate 302 fixedly connected between its inner wall and the outer end of the fixing frame 1.

[0029] There are three guide inner threaded sleeves 106, and the guide inner threaded sleeves 106 are movable at the outer end of the fixed frame 1. The positioning cover 3 is fixedly connected to the four sides of the outer surface of the fixed plate 3, and the inner surface of the fixed plate 301 is provided with mounting holes.

[0030] This technical solution: By setting the positioning cover 3, it can provide protection to the outside of the drive gear 103 and the driven gear 105, ensuring safety during use. With the assistance of the fixing plate 301 and the connecting plate 302, the position of the fixing frame 1 can be fixed after the positioning cover 3 is installed. Then, after inserting one end of the tool sleeve into the outside of the matching socket head 102, the tool sleeve drives the rotating rod 101 and the drive gear 103. When the drive gear 103 rotates, it can drive the guide inner thread sleeve 106 to rotate through the meshing driven gear 105. When the guide inner thread sleeve 106 rotates, the ejector screws 104 connected inside the three guide inner thread sleeves 106 can extend simultaneously. After the right side of the ejector screw 104 contacts the worn part, it is ejected, so that the bowl-shaped tile can restore its shape, thereby avoiding the phenomenon of uneven ejection due to uneven force and facilitating the use of the operator.

[0031] Example 2

[0032] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, the outer surface of the guide inner threaded sleeve 106 is provided with a plurality of balls 107.

[0033] This technical solution: By setting the ball bearing 107, the resistance when the guide inner thread sleeve 106 rotates at the outer end of the fixed frame 1 can be reduced, which helps to reduce the physical exertion of the workers.

[0034] Example 3

[0035] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, an arc-shaped connector 2 is fixedly connected between the left ends of two adjacent ejector screws 104.

[0036] This technical solution ensures that the three ejector screws 104 can move forward and backward synchronously by setting the arc-shaped connector 2, and also ensures the stability of the ejector screws 104 during ejection operation.

[0037] Example 4

[0038] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a connecting post 303 is fixedly connected to the left side of the fixing frame 1, and the left side of the connecting post 303 is fixedly connected to the inner wall of the positioning cover 3.

[0039] This technical solution: By setting the connecting column 303, the connection strength and stability between the fixing frame 1 and the positioning cover 3 can be further enhanced.
