Description

Technical Field

[0001] The utility model belongs to the technical field of medicine grinding equipment, and particularly relates to an adjustable medicine grinding device. Background Art

[0002] During drug testing, solid drugs need to be ground and crushed using grinding equipment to improve their solubility and uniformity, and to reduce errors in test data. Existing drug grinding equipment often has difficulty adjusting the gap between the grinding head and the inner wall of the mortar. This results in a single particle size of the ground powder particles, making it impossible to adjust the particle size in a targeted manner. Furthermore, drug residue remains on the inner wall of the mortar, making it difficult to clean. Therefore, there is an urgent need to provide an adjustable drug grinding device that can adjust the gap between the grinding head and the inner wall of the mortar to improve its practicality. Utility Model Content

[0003] In response to the deficiencies in the background technology, the utility model provides an adjustable medicine grinding device, which can freely adjust the gap between the grinding head and the inner wall of the mortar, so as to not only make targeted adjustments to the size of the medicine grinding particles, but also facilitate the cleaning of the inner wall of the mortar, thereby greatly improving the practicality of the device.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0024] like Figure 1As shown, an adjustable drug grinding device includes a base 1, with two columns 2 symmetrically arranged on either side of the base's upper end. The tops of the two columns are connected to a crossbeam 3, which is equipped with a motor 4. The motor's output shaft is connected to a grinding ball 5. The grinding ball cooperates with a mortar 6 located below it. During operation, the grinding ball is located inside the mortar and is driven by the motor to rotate, grinding the drug between the grinding ball and the inner wall of the mortar. The mortar is slidably connected to the two columns located on either side. The base is equipped with an adjustment mechanism that drives the mortar to slide up and down along the two columns. The operator adjusts the height of the mortar to adjust the size of the gap between the grinding ball and the inner wall of the mortar. The vertical cross-section of the mortar is U-shaped, and the bottom of its inner wall is hemispherical to match the size of the grinding ball, matching the shape of the grinding ball, effectively improving the drug grinding effect. There are wing plates 7 on the upper ends of both sides of the mortar, and each wing plate is provided with a sliding hole 701. Each column passes through the corresponding sliding hole and is slidably connected with it, effectively ensuring the stability of the lifting movement of the mortar. A limit block 8 is provided on the upper part of each column to limit the rising height of the mortar.

[0025] like Figure 1 As shown, the adjustment mechanism includes a screw 9 and a crank 10. The upper end of the screw is rotatably connected to the bottom of the mortar, while the lower end is threadedly connected to the base and connected to the crank. The operator grasps and rotates the crank to adjust the height of the mortar. The vertical cross-section of the base is a rectangular frame with a cavity 101 in the middle. The crank is located in the cavity in the middle of the base. Placing the crank in the cavity protects it from accidental contact that may affect the quality of the drug grinding.

[0026] Combine Figure 2 As shown, a discharge port 11 is provided at the lower portion of the mortar near one of the columns. A plug 12 is installed at the discharge port. One side of the plug is connected to a first sleeve 14 via a telescopic rod 16 and a spring 13. The spring is mounted on the telescopic rod. The first sleeve is slidably connected to the corresponding column. A first locking rod 15 is threadedly connected to the side wall of the first sleeve. When the first locking rod is tightened, its end contacts the column, thereby securing the position of the first sleeve. When the telescopic rod is shortened, the plug can be removed from the discharge port to discharge the material. The first telescopic rod consists of a hollow tube 1602 and a movable tube 1601, one end of which is located within the hollow tube. To prevent the ground medicine from scattering during discharge, a receiving hopper 17 is located directly below the discharge port. A support rod 18 is connected to one side of the receiving hopper, and a second sleeve 19 is connected to the end of the support rod. The second sleeve is slidably connected to the corresponding column. A second locking rod 20 is threadedly connected to the side wall of the second sleeve. The second sleeve is locked in the same manner as the first sleeve. The discharge port in this embodiment is located slightly below the side of the mortar. This prevents a large amount of medicine from spilling directly out of the discharge port after the plug is opened, and ensures that the ground medicine in the mortar can be cleaned with the help of auxiliary tools.

[0027] The working principle of this utility model is as follows:

[0028] like Figure 1 and Figure 2 As shown, when in use, first pour the solid medicine to be ground into the mortar 6, then rotate the crank 10 to drive the mortar 6 to rise along the two columns 2, and when the mortar 6 reaches the appropriate height (determined by the required drug particle size), stop rotating the crank 10, slide the first sliding sleeve 14 upward along the corresponding column 2, and then insert the plug 12 into the discharge port 11 of the mortar 6, tighten the first locking rod 15, and then start the motor 4 to drive the grinding ball 5 to rotate to grind the medicine. When grinding is complete, the motor 4 stops, the first locking rod 15 is slightly loosened (preferably to prevent the first sleeve from sliding down the column automatically), and the first sleeve 14 is held with one hand while the crank handle 10 is rotated in the opposite direction with the other hand to lower the mortar 6. When it reaches the desired height, the first locking rod 15 is tightened, the second sleeve 19 is adjusted to the desired height, the plug 12 is pulled outward, and the medicine in the mortar 6 is discharged from the discharge port 11 using a brush or scraper, falling into the receiving funnel 17 to complete the discharge of the medicine. After the medicine is discharged, the inner wall of the mortar 6 is cleaned.

[0029] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.
