[0040] The laboratory single mineral crusher provided by the utility model is described in detail below with reference to the embodiments.

[0041] Example

[0042] like Figures 1 to 4 As shown, this embodiment provides a laboratory single mineral crusher, including: a structural support frame 1, a striking device connected to the top of the structural support frame 1, a processing tank used in conjunction with the striking device, and a control device 4 for controlling the striking device.

[0043] The structural support frame 1 includes a top structure 11 , a bottom structure 12 , and a vertical structure 13 for connecting the top structure 11 and the bottom structure 12 .

[0044] The striking device includes a power device 21 and a striking member connected to the power device 21. The power device 21 includes a metal sleeve 211 connected to the top of the striking member, a first piston 212 and a second piston 213 movably disposed in the inner cavity of the metal sleeve 211, an eccentric wheel 215 connected to the second piston 213 via a transmission rod 214, and a motor 217 connected to the eccentric wheel 215 via a transmission shaft 216. The first piston 212, the second piston 213, and the metal sleeve 211 form a sealed pressure chamber. The second piston 213 is in the shape of a semi-convex character. The striking member includes a metal rod 221 connected to the top of the first piston 212, a chuck 222 connected to the bottom of the metal rod 221, a hammer rod 223 connected to the chuck of the chuck 222, and a hammer head 224 connected to the bottom of the hammer rod 223.

[0045] The processing tank includes a tank body 31 for containing materials, an upper cover 32 threadedly connected to the tank body 31, and a base 33 connected to the bottom end of the tank body 31. The upper cover 32 is provided with a hole for passing the hammer rod 223; the upper cover 32 is arc-shaped.

[0046] The power device 21 is disposed within the top frame 11 of the structural support frame 1. The base 33 is embedded within the bottom frame 12 of the structural support frame 1. A shock-absorbing spring 5 is disposed between the top of the power device 21 and the top of the top frame 11. A detachable counterweight 6 is disposed on the top frame 11.

[0047] The control device 4 includes a central control system for controlling the working time and striking frequency of the striking device, an input system 41 for realizing human-computer exchange, a display screen 42 for displaying the set time and striking frequency, and a power switch 43 for controlling the on state of the striking device.

[0048] The following is an explanation of the working process of a laboratory single mineral crusher provided by the utility model:

[0049] like Figures 1 to 4As shown, the base 33 of the processing tank is inserted into the groove of the bottom frame 12 of the structural support frame 1. The tank body 31 is filled with a suitable amount of single-mineral ore. The hammer rod 223 is then passed through the hole in the upper cover 32 of the processing tank. The chuck 222 grips the top of the hammer rod 223. The hammer head 224 is then placed in the tank body 31. The upper cover 32 and the tank body 31 are threaded together, and the processing tank is closed. A low striking frequency and time are then set on the input system 41. The power switch 43 is turned on to start the motor 217. The sample is initially rough-processed. After the set time is reached, the motor 217 stops. The chuck 222 is then separated from the hammer rod 223. After opening the upper cover 32, the hammer rod 223 and hammer head 224 are removed, along with the processing tank. The sample is then removed for impurity removal. Repeat the above operation for the cleaned samples and re-set the appropriate (higher) beating frequency and (longer) time on the input system 41 to further crush and remove impurities until all samples are cleaned. Finally, the cleaned samples are sieved to obtain samples of appropriate particle size, and unqualified samples are returned to the processing tank for further crushing until all samples have the acceptable particle size. The working principle of the striking device is as follows: the motor 217 drives the eccentric wheel 215 to perform circular motion, thereby driving the transmission rod 214 to perform linear reciprocating motion (this is not a completely linear motion, and this motion mode is a prior art); when the transmission rod 214 moves in the direction close to the first piston 212, the second piston 213 connected to the transmission rod 214 performs linear motion in the metal sleeve 211 in the direction close to the first piston 212, and when the second piston 213 moves in the direction close to the first piston 212, the pressure in the pressure chamber increases, which pushes the first piston 212 to move in the direction away from the second piston 213. Under the action of the first piston 212, the metal rod 22 connected to the first piston 212 1 will move downward; and when the transmission rod 214 moves in the direction away from the first piston 212, the second piston 213 connected to the transmission rod 214 also performs a linear motion in the direction away from the first piston 212 in the metal sleeve 211. When the second piston 213 moves in the direction away from the first piston 212, the pressure in the pressure chamber becomes smaller, which will push the first piston 212 to move in the direction close to the second piston 213. Under the action of the first piston 212, the metal rod 221 connected to the first piston 212 will move upward; in this reciprocating motion, the metal rod 221 is pushed to perform a linear telescopic reciprocating motion, thereby providing power to the striking component, thereby driving the hammer head 224 to continuously strike the sample.

[0050] In summary, the utility model provides a laboratory single mineral crusher, which comprises a striking device arranged at the top of a structural support frame, a processing tank used in conjunction with the striking device, and a control device for controlling the striking device; wherein the power device in the striking device is provided by movably arranging a first piston and a second piston in the inner cavity of a metal sleeve, an eccentric wheel connected to the second piston through a transmission rod, and a motor connected to the eccentric wheel through a transmission shaft; thus, the striking device is driven to perform reciprocating linear motion by the motor and the eccentric wheel structure, thereby realizing the crushing operation of the sample, thereby replacing manual crushing, greatly improving work efficiency, and saving a lot of manpower and material resources. In addition, the control device is provided with a central control system for controlling the working time and striking frequency of the striking device, an input system for realizing human-machine exchange, and a display screen for displaying the set time and striking frequency, that is, the striking frequency and time of the striking device can be controlled by the central control system, and the appropriate striking frequency and time can be selected according to different crushing requirements.
