DETAILED DESCRIPTION
[0018] 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.
[0019] like Figures 1 to 4 As shown:
[0020] Embodiment 1: The utility model provides a laboratory medicine grinder, comprising: a lifting mechanism 1, including a base assembly 11, an upper support assembly 12 slidably embedded on the base assembly 11, an electric push rod 13 for driving the upper support assembly 12 to rise, and a grinding bowl 14 embedded on the base assembly 11; a grinding mechanism 2, including a rotating assembly 21 installed on the upper support assembly 12, a driving assembly 22 for driving the rotating assembly 21 to rotate, and a group of grinding rod assemblies 23 embedded at the bottom of the rotating assembly 21; a group of grinding rod assemblies 23 can be placed in the grinding bowl 14;
[0021] Among them, by controlling the operation of the electric push rod 13, the upper support assembly 12 can be raised or lowered, and the medicine is placed in the grinding bowl 14. The electric push rod 13 is controlled to lower the upper support assembly 12. The lowering of the upper support assembly 12 causes the grinding mechanism 2 to lower. The lowering of the grinding mechanism 2 causes a group of grinding rod assemblies 23 to extend into the grinding bowl 14. Turning on the drive assembly 22 can cause the rotating assembly 21 to rotate. The rotation of the rotating assembly 21 causes a group of grinding rod assemblies 23 to rotate. The rotation of a group of grinding rod assemblies 23 can grind the medicine. When the grinding is completed, the electric push rod 13 is controlled to raise the upper support assembly 12, and the grinding mechanism 2 follows the rise. The staff can easily remove the grinding bowl 14 from the base assembly 11.
[0022] Specifically, the base assembly 11 includes a base body 111 . A positioning groove 112 is formed on the upper side of the base body 111 . A group of guide rods 113 are fixedly connected to the upper side of the base body 111 .
[0023] Specifically, the upper support assembly 12 includes a connecting frame 121 , a slider 122 is fixedly connected to the bottom of the connecting frame 121 , and a bracket 123 and a bracket 2 124 are fixedly connected to one side of the connecting frame 121 in parallel.
[0024] Specifically, the slider 122 is slidably embedded in the guide rod 113 , the lower end of the electric push rod 13 is fixedly connected to the base body 111 , the upper end of the electric push rod 13 is fixedly connected to the slider 122 , and the grinding bowl 14 is limitedly embedded in the positioning groove 112 .
[0025] As can be seen from the above, turning on the electric push rod 13 can make the connecting frame 121 rise or fall along the guide rod 113 through the slider 122. When the connecting frame 121 rises or falls, the grinding mechanism 2 can follow it to rise or fall. The grinding bowl 14 is placed in the positioning groove 112 to play a limiting role, avoiding the grinding bowl 14 from moving during grinding.
[0026] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the rotating assembly 21 includes a rotating rod 211, the outer side of the rotating rod 211 is fixedly connected to a gear 1 212, the lower end of the rotating rod 211 is fixedly connected to a positioning frame 213, and a limiting groove 214 is provided inside the positioning frame 213; the driving assembly 22 includes a motor 221, the upper end of the motor 221 is fixedly connected to a gear 2 222; the rotating rod 211 is fixedly mounted on the bracket 1 123 and the bracket 2 124 through bearings, the motor 221 is fixedly mounted on the bracket 2 124, and the gear 2 222 and the gear 1 212 are meshed with each other.
[0027] Specifically, the grinding rod assembly 23 includes a grinding rod body 231, the lower end of the grinding rod body 231 is fixedly connected to a grinding head 232, the upper end of the grinding rod body 231 is fixedly connected to a limiting block 233, and the upper side of the limiting block 233 is fixedly connected to a spring 234; the limiting block 233 and the spring 234 are limitedly embedded in the limiting groove 214, and the grinding head 232 can be placed in the positioning groove 112.
[0028] As can be seen from the above, turning on the motor 221 can make the gear 222 drive the gear 1 212 to rotate, and the rotation of the gear 1 212 drives the rotating rod 211 to rotate, and the rotation of the rotating rod 211 makes the positioning frame 213 drive the grinding rod body 231 to rotate, and the rotation of the grinding rod body 231 drives the grinding head 232 to rotate in the grinding bowl 14, thereby playing a grinding role. When the connecting frame 121 drives the bracket 1 123 and the bracket 2 124 to descend, the rotating rod 211 and the positioning frame 213 follow and descend. When the grinding head 232 contacts the bottom of the grinding bowl 14, the rotating rod 211 and the positioning frame 213 continue to descend, so that the spring 234 is partially compressed in the limiting groove 214. At this time, the pressure generated by the grinding head 232 in the grinding bowl 14 is greater. At the same time, since the spring 234 still has room for further compression, the grinding head 232 will not cause damage to the grinding bowl 14 under the buffering of the spring 234.
[0029] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
