Detailed Description

In order that the present disclosure may be more clearly and readily understood, reference will now be made in detail to the present disclosure as illustrated in the accompanying drawings.

The first embodiment is as follows: as shown in fig. 1 to 4, the particulate drug grinding machine for hepatobiliary surgery of this embodiment includes a machine base 2 having a grinding chamber 1 and a grinding disc 3 located in the grinding chamber 1, the grinding chamber 1 is cylindrical, the grinding disc 3 is disc-shaped and is adapted to the shape of the grinding chamber 1, when the grinding disc 3 is pressed down, the particulate drug in the grinding chamber 1 can be ground into powder, a bottom plate 4 and a connecting plate 5 are disposed on one side of the machine base 2, the bottom plate 4 is located below the connecting plate 5, a fixing frame 6 is fixed on the bottom plate 4, a driving gear 7 and a rocking handle 8 are disposed on the fixing frame 6, the driving gear 7 is rotatably connected to the fixing frame 6 through the rocking handle 8, the connecting plate 5 is fixed with a connecting cylinder 9, a fixing cylinder 10 is connected to the connecting cylinder 9, the fixing cylinder 10 is fixedly connected to the connecting cylinder 9 by being inserted and inserted up and down, a screw 11 is disposed in the fixing cylinder 10, a driven gear 12, driven gear 12 passes through bearing or axle sleeve and is connected with connecting cylinder 9 rotation, and screw rod 11 can rotate relative fixed cylinder 10 like this, and driven gear 12 sets up with drive gear 7 meshing moreover, and when rotating rocking handle 8, drive gear 7 can drive screw rod 11 internal rotation at fixed cylinder 10 through driven gear 12. A movable barrel 13 is arranged outside the fixed barrel 10, the outer wall of the movable barrel 13 is connected with the grinding disc 3 through a rocker 14, a threaded sleeve 15 is connected on the screw rod 11 in a threaded manner, part of the threaded sleeve 15 extends out of the fixed barrel 10 and then is fixedly connected with the inner wall of the movable barrel 13, specifically, a guide groove 16 is arranged on the fixed barrel 10, a guide block 17 is fixedly connected on the threaded sleeve 15, the guide block 17 is matched and connected with the guide groove 16 and is fixedly connected with the inner wall of the movable barrel 13, so that when the screw rod 11 rotates in the fixed barrel 10, the screw rod 11 can drive the movable barrel 13 to ascend or descend along the fixed barrel 10 through the threaded sleeve 15, so that the driving gear 7 is driven to rotate and the driven gear 12 is driven to rotate by rotating the rocking handle 8, the threaded sleeve 15 moves on the screw rod 11, and finally the grinding disc 3 ascends or descends to grind the granular medicines in the grinding cavity 1, the structure is simple, and the medicine grinding can be realized manually, so that the operation of a user is convenient.

The top of abrasive disc 3 of this embodiment is equipped with connecting axle 18, connecting axle 18 passes through adjust knob 19 and is connected with rocker 14, can adjust the effective connection length of connecting axle 18 through revolving wrong adjust knob 19, and then realize that abrasive disc 3 is installed on rocker 14 height-adjustably, in order to satisfy the granule medicine grinding of different volumes, because movable cylinder 13 is limited along the distance that fixed cylinder 10 descends, also the distance that abrasive disc 3 descends is limited, if the granule medicine in grinding chamber 1 is too little, if not adjust the height of abrasive disc 3 on rocker 14, then can't realize the grinding function. Specifically, a sleeve 20 is fixed on one side of the rocker 14 close to the connecting shaft 18, the connecting shaft 18 penetrates through the sleeve 20 and then is in threaded connection with an adjusting knob 19, an adjusting spring 21 is arranged between the sleeve 20 and the top of the grinding disc 3, the adjusting spring 21 is sleeved on the connecting shaft 18, a threaded section is arranged on the top of the connecting shaft 18, when the adjusting knob 19 is screwed, the adjusting spring 21 is compressed, the top of the connecting shaft 18 gradually extends out of the sleeve 20, the height of the grinding disc 3 is raised, and therefore the grinding disc 3 is mounted on the rocker 14 in a height-adjustable mode.

In order to facilitate getting the material after the grinding, this embodiment sets up guide way 16 into vertical groove 22 and arc wall 23, arc wall 23 sets up with the top intercommunication in vertical groove 22, when guide block 17 removes along vertical groove 22, can realize that movable section of thick bamboo 13 goes up and down along fixed cylinder 10, and then realize abrasive disc 3 goes up and down in vertical direction, when guide block 17 removes along arc wall 23, can realize that movable section of thick bamboo 13 rotates along fixed cylinder 10, and then realize abrasive disc 3 and rotate in the horizontal direction. After the grinding is finished, the rocking handle 8 is rotated anticlockwise, so that the guide block 17 moves upwards in the vertical groove 22 firstly, and then moves in the arc-shaped groove 23, so that the grinding disc 3 ascends along the fixed cylinder 10 firstly to leave the grinding cavity 1, and then rotates along the fixed cylinder 10 to rotate out of the grinding cavity 1 as shown in fig. 2, and at the moment, the material taking of a user cannot be blocked.

Example two: different from the first embodiment, the present embodiment further includes a grinding cover 24 capable of replacing the grinding disc 3 as shown in fig. 5, a motor 25 is disposed in the grinding cover 24, and a grinding blade 27 is connected to a motor shaft 26 of the motor 25 after penetrating through the bottom of the grinding cover 24. Can realize manual grinding when adopting abrasive disc 3, can realize electronic the grinding when adopting grinding lid 24, this embodiment has two kinds of grinding modes like this, can adopt different grinding modes to the medicine of different hardness, so can a tractor serves two-purpose, and user experience feels good. That is, the grinder of the present embodiment has a first grinding mode in which the grinding plate 3 is coupled in the grinding chamber 1 and ascends and descends in the grinding chamber 1 to grind the medicine, and a second grinding mode in which the grinding cover 24 is coupled in the grinding chamber 1 and drives the grinding blade 27 to rotate by the motor 25 to grind the medicine.

The grinding chamber 1 of this embodiment is the tube-shape, grind lid 24 for discoid and with grinding chamber 1 shape adaptation and can seal grinding chamber 1, should grind lid 24 and include upper cover 28 and lower cover 29, upper cover 28 and lower cover 29 surround and form the installation cavity 30 of installation motor 25, motor shaft 26 runs through the bottom center setting of lower cover 29, this installation cavity 30 sets up in upper cover 28 bottom center, lower cover 29 bottom center is equipped with ascending sealed arch 31, for example, lock joint formula installation after lower cover 29 is installed to put in place on upper cover 28, sealed arch 31 covers installation cavity 30, motor shaft 26 runs through behind the bottom center of sealed arch 31 and grinds sword 27 fixed connection. The top of the upper cover 28 is provided with a connecting shaft 18, the connecting shaft 18 is connected with the rocker 14 through an adjusting knob 19, that is, the mounting structure of the upper cover 28 and the rocker 14 is the same as that of the grinding disc 3 and the rocker 14 in the first embodiment, which is not described herein again, so that the grinding cover 24 is also height-adjustably coupled in the grinding chamber 1.
