In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0029] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0030] See also Figure 1-5 The utility model provides a technical solution: a drug sieve for particle size inspection, comprising a casing 1 with an open top and a filter 3, the filter 3 can move vertically in the casing 1, and a plurality of guide rods 2 are vertically arranged in the casing 1, the plurality of guide rods 2 penetrate the filter 3 up and down, and slideably cooperate with the filter 3;

[0031] A pushing mechanism for driving the filter element 3 to move vertically in the housing 1 is also provided in the housing 1 .

[0032] In this solution, four guide rods 2 are provided and are respectively located at four corners in the housing 1 , and the four guide rods 2 pass through the four corners of the filter element 3 correspondingly.

[0033] According to the need of drug particle screening, a suitable filter element 3 is placed on the guide rod 2, and the filter element 3 is penetrated by the guide rod 2, so that the filter element 3 moves downward along the length direction of the guide rod 2 until the bottom of the filter element 3 contacts the pushing mechanism; and then before use, the drug particles to be screened are guided on the filter element 3, and the filter element 3 is driven to move up and down by the pushing assembly. As the filter element 3 moves, the drug particles on the filter element 3 are screened through the filter holes on the filter element 3;

[0034] When the filter element 3 in the housing 1 needs to be removed, the user directly lifts the filter element 3 and moves it upward along the guide rod 2 until the filter element 3 is separated from the through connection with the guide rod 2; the replaced filter element 3 is placed in the housing 1 so that it is penetrated by the guide rod 2 and the bottom is in contact with the pushing mechanism. This installation method allows the user to directly lift the filter element 3 out of the housing 1 when the filter element 3 needs to be removed, effectively reducing the time consumed by the staff to remove and replace the filter element 3.

[0035] In this embodiment, the driving mechanism includes a motor 701 and a rotating disk 7. The motor 701 is installed on one side of the casing 1, and the output end passes through the side wall of the casing 1 and is fixedly connected to the rotating disk 7. A plurality of contact points protruding outward are arranged on the outer edge of the top surface of the rotating disk 7. The distances between adjacent contact points and the axis of the rotating disk 7 are not equal, and any contact point protrudes outside the line connecting the two adjacent contact points.

[0036] When in use, the motor 701 is started to drive the rotating disk 7 to rotate. During the rotation process, the irregular contact points on the rotating disk 7 successively contact and lift the bottom of the filter 3. Since the distance between each contact point and the axis of the rotating disk 7 is not equal, the height of the filter 3 lifted by each contact point is also inconsistent. Therefore, when the rotating disk 7 rotates at a high speed, the filter 3 is quickly lifted by each contact point. Since the lifting height is not consistent, the filter 3 is bumped up and down, and then the medicine particles on the filter 3 are shaken and screened, and the amplitude of the bumping and shaking is irregular, which is convenient for promoting the medicine particles to pass through the filter holes.

[0037] Among them, the model of motor 701 is 1LE0001-1CB0.

[0038] In this embodiment, the side wall between two adjacent contact points is in an inwardly curved shape.

[0039] Because the side wall between the two contact points is curved inwardly, the filter element 3 will not contact the side wall of the rotating disk 7 during the rotation of the rotating disk 7, and the filter element 3 will not be buffered by the side wall of the rotating disk 7 during the up and down bumping process, thereby reducing the bumping effect.

[0040] In this embodiment, mounting frames 5 are provided on both sides of the housing 1 opposite to the opening. One end of the mounting frame 5 is rotatably matched with the housing 1, and a roller 6 is rotatably provided on the other end.

[0041] When not in use, the two mounting frames 5 are respectively located on both sides of the casing 1. When in use, one end of the mounting frame 5 is rotated to place the roller 6 arranged on the other end on the filter element 3. When the filter element 3 moves upward or downward, the two rollers 6 are affected by the length of the mounting frame 5, so that the two rollers 6 roll in a direction of relative proximity or relative distance. During the rolling process, the stacked medicine particles are collided with by the rollers 6 to break them up, so that the medicine particles are not easily reduced in screening efficiency due to stacking.

[0042] Wherein, the surface of the drum 6 is provided with a sponge layer.

[0043] In this embodiment, a plurality of protrusions 601 are provided on the surface of the drum 6 .

[0044] During the rolling process, the drum 6 penetrates the filter holes on the filter element 3 through the protrusions 601 to clear the filter holes, so that the filter holes are not easily blocked by medicine particles to reduce the screening efficiency.

[0045] Among them, a plurality of protrusions 601 are arranged along the circumference and length direction of the drum 6 .

[0046] In this embodiment, the mounting frame 5 includes an axle rod 501 and two connecting rods 502. The roller 6 is rotatably mounted on the axle rod 501. The axle rod 501 is connected to the lower ends of the two connecting rods 502. Insertion rods 503 are relatively arranged at the upper ends of the two connecting rods 502. Both mounting shells 4 are provided with slots 401 for inserting the insertion rods 503. The two connecting rods 502 are rotatably connected with the slots 401 through the two insertion rods 503.

[0047] By squeezing the two connecting rods 502 in the direction in which they are to be brought closer, the inserting rods 503 on the two connecting rods 502 are respectively disengaged from the two slots 401 , thereby disassembling the mounting frame 5 and the roller 6 , making it easier to replace or clean the roller 6 .

[0048] In this embodiment, the filter element 3 includes a filter plate 301, a frame 302 and two handles 303, the upper end of the guide rod 2 passes through the filter plate 301, the frame 302 is fixed on the top of the filter plate 301, and the two handles 303 are respectively arranged on opposite sides of the filter plate 301.

[0049] The frame 302 surrounds and protects the medicine particles on the filter plate 301 , so that it is not easy for them to slide out and fall from the side of the filter plate 301 .

[0050] In this embodiment, a supporting leg 8 is provided at the bottom of the casing 1, a base 9 is provided at the bottom of the supporting leg 8, the lower end of the supporting leg 8 passes through the top and is provided with a limiting plate 801, a buffer spring 901 is provided in the base 9, and the two ends of the buffer spring 901 are respectively abutted against the limiting plate 801 and the inner wall of the base 9.

[0051] When in use, the vibration generated by the operation of the rotating disk 7 and the filter element 3 is transmitted into the base 9 through the supporting legs 8, and the vibration is effectively buffered by the buffer spring 901 in the base 9, thereby reducing the vibration of the device.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
