[0026] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The present invention is further described in detail below in conjunction with the embodiments:

[0028] Example 1

[0029] like Figure 1-5 As shown, the utility model provides a grinding device for drug testing, including a grinding bucket 1, a support frame 2 and an electric push rod 7, the bottom end of the support frame 2 is fixedly connected to a supporting bottom ring 4, the upper surface of the supporting bottom ring 4 is fixedly connected to a buffer spring 3, a feeding hole 10 is opened at the bottom of the inner wall of the grinding bucket 1, a grinding head 5 for grinding is arranged above the grinding bucket 1, and a material receiving box 11 is arranged below the grinding bucket 1.

[0030] The bottom end of the grinding head 5 is fixedly connected to a closed bottom rod 9 for closing the feed hole 10. The upper surface of the grinding head 5 is rotatably connected to a mounting plate 6 via a connecting rod. One end of the connecting rod that passes through the upper surface of the mounting plate 6 is fixedly connected to a driving motor 8.

[0031] The bottom end of the electric push rod 7 is fixedly connected to the upper surface of the mounting plate 6 , and a feeding hopper 14 for feeding is fixedly connected to one side of the grinding hopper 1 .

[0032] Example 2

[0033] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the top of the buffer spring 3 is fixedly connected to the bottom surface of the grinding bucket 1, the outer wall of the closed bottom rod 9 is plugged into the inner wall of the feeding hole 10, the electric push rod 7 is started to drive the grinding head 5 to move up through the mounting plate 6, and the grinding head 5 drives the closed bottom rod 9 to be pulled out from the feeding hole 10 during the upward movement, and the feeding hole 10 is opened. At this time, the ground medicine falls into the sieve 12 through the feeding hole 10, and after being filtered by the sieve 12, it falls into the receiving box 11, and then the medicine with larger particles can be put into the feed hopper 14 again for re-grinding. By using the closed bottom rod 9 at the bottom of the grinding head 5 and the feeding hole 10 on the inner wall of the grinding bucket 1, the ground medicine in the grinding bucket 1 can be directly discharged into the receiving box 11 through the feeding hole 10, thereby facilitating the discharge work of the grinding bucket 1.

[0034] The upper surface of the material receiving box 11 is sleeved with a mounting collar 13 , the bottom surface of the material receiving box 11 overlaps with the upper surface of the supporting bottom ring 4 , and the inner wall of the mounting collar 13 is fixedly connected to the screen 12 .

[0035] The upper surface of the support frame 2 is provided with a placement groove for placing the drive motor 8 .

[0036] The working principle of the grinding device for drug testing will be described in detail below.

[0037] like Figure 1-5 As shown, when in use, the medicine to be ground is put into the grinding bucket 1 through the feed hopper 14, and then the electric push rod 7 starts to push the mounting plate 6 to drive the grinding head 5 to move down to a suitable position, and then the external drive motor 8 is started, so that the drive motor 8 drives the grinding head 5 to rotate to grind the medicine in the grinding bucket 1.

[0038] When the grinding is in place, the electric push rod 7 is started to drive the grinding head 5 to move upward through the mounting plate 6. During the upward movement of the grinding head 5, the closed bottom rod 9 is driven to be withdrawn from the discharge hole 10, and the discharge hole 10 is opened. At this time, the ground medicine falls through the discharge hole 10 into the sieve 12, and after being filtered by the sieve 12, it falls into the receiving box 11, and then the medicine with larger particles can be put into the feed hopper 14 again for re-grinding processing.

[0039] During the grinding process of the grinding head 5, the grinding bucket 1 is impacted by the rotation of the grinding head 5, which compresses the buffer spring 3 at the bottom of the grinding bucket 1. The buffer spring 3 generates a reaction force to put the grinding bucket 1 in a vibrating state, and then the medicine is in a shaking state on the inner wall of the grinding bucket 1, thereby improving the grinding effect of the medicine.

[0040] It should be noted that, in this article, the terms "comprises", "includes" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or still includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements. The above generally describes the utility model in detail, but on the basis of the utility model, some modifications or improvements can be made to it, which is obvious to a general technician in the technical field. Therefore, modifications or improvements that do not deviate from the spirit of the utility model are within the scope of protection of the utility model.
