[0002] There are numerous drug detection items, including drug quality detection, drug ingredient detection, drug defect detection, etc. The purpose of drug detection is to prevent unqualified drugs from entering the market and ensure the safety of drugs. Therefore, the drug detection process is crucial.

[0003] The patent with the patent announcement number CN208654137U discloses a drug detection device, which includes a base. The upper side wall of the base is fixedly connected with a reaction device. The upper side wall of the base is fixedly connected with a fixed block through a support device. The lower side wall of the fixed block is fixedly connected with a liquid dropping device. A crushing cavity is opened in the fixed block, and motor slots are symmetrically opened on the side wall of the crushing cavity. In this patent, the solid drug to be detected is placed in the crushing cavity. The motor is turned on, and the output shaft drives the third bevel gear to rotate, thereby driving a plurality of second bevel gears to rotate, thereby driving a plurality of first bevel gears to rotate, thereby driving a plurality of threaded rods to rotate, so that two toothed plates move relative to each other, and the solid drug between the two toothed plates is crushed into powder, and then enters the dissolution reaction link through the material outlet on the blanking plate. This process enables the solid drug to dissolve more fully after becoming powder, improving the accuracy of the detection result.

[0004] However, this device still has deficiencies: The device conducts subsequent detection by stirring the drug into powder. However, during the drug crushing process, it is difficult for the crushing component to reciprocate up and down to crush the solid drug, resulting in potentially unsatisfactory local crushing of the solid drug, indirectly affecting the subsequent dissolution and detection results.

[0007] The baffle is disengaged from the contact with the inclined surface of the inclined plate, prompting the inclined plate to swing downward, and then the inclined plate is reset by the reset plate, so that the powder produced by the medicine crushed is blocked when the inclined plate swings up and down.

[0008] According to the above technical solution, the anti-mixing device includes an electric telescopic rotating column, a connecting plate and a convex ball rod. The top of the electric telescopic rotating column is rotatably installed at the center of the top inner wall of the separation barrel, and an arc groove is opened on the outer wall of the electric telescopic rotating column. When the electric telescopic rotating column is started, the telescopic end of the electric telescopic rotating column drives the connecting plate to move up and down and rotate. The top of the connecting plate is fixedly installed at the bottom of the telescopic end of the electric telescopic rotating column. The top of the convex ball rod is fixedly installed at the bottom of the connecting plate, and the convex ball on the outer wall of the convex ball rod is rotatably installed. The connecting plate drives the convex ball rod to move synchronously. The convex ball rod stirs the powder to promote uniform combination of the powder and the separation liquid.

[0009] According to the above technical solution, the anti-mixing device also includes a separation plate, a spring piece, a T-shaped slide plate and an arc-shaped knocking rod. The left side of the separation plate is fixedly mounted on the right side of the outer wall of the convex ball rod. The convex ball rod drives the separation plate to move synchronously. The separation plate salvages part of the block powder inside the separation barrel to prevent the block powder from being stored for a long time and difficult to decompose in time. The right side of the spring piece is fixedly mounted on the left side of the outer wall of the convex ball rod. The convex ball rod drives the spring piece to move synchronously. The spring piece is deformed by the rotating centrifugal force and the resistance of the treatment liquid. The left side of the T-shaped slide plate penetrates and is fixed It is installed on the concave surface of the spring piece, and the back of the T-shaped slide is in contact with the back of the inner wall of the separation plate. When the spring piece is deformed and restored, it drives the T-shaped slide to slide left and right along the inner wall of the separation plate.

The arc-shaped knocking rod is fixedly installed between the left side of the T-shaped slide and the right side of the inner wall of the separation plate, and the back of the arc-shaped knocking rod is in contact with the back of the inner wall of the separation plate. The T-shaped slide squeezes the arc-shaped knocking rod to deform synchronously and move away from the separation plate. When the arc-shaped knocking rod is restored, it knocks back and forth on the inner wall of the separation plate to generate vibration, thereby avoiding residual residue after the block powder is crushed.

[0010] According to the above technical solution, the centering device includes a cross bar, a heating ring and a swing plate. The right side of the cross bar is slidably installed inside the arc groove of the electric telescopic rotating column. When the electric telescopic rotating column rotates, the arc groove restricts the cross bar, causing the cross bar to move up and down. The left side of the inner wall of the heating ring is fixedly installed on the left side of the cross bar, and the outer wall of the heating ring is slidably connected to the inner wall of the separation barrel. The cross bar drives the heating ring to slide up and down along the inner wall of the separation barrel, thereby expanding the heating range of the heating ring. The top of the swing plate is hinged at the bottom edge of the heating ring, and the heating ring drives the swing plate to move synchronously. The swing plate causes the liquid to gather in the center, thereby improving the separation effect of the powder.

[0011] According to the above technical solution, the centering device also includes a torsion plate, a through rod, a transmission plate and a rubber wheel. The torsion plate is fixedly installed between the left side of the inner wall of the heating ring and the top inclined surface of the swing plate. When the swing plate swings, the torsion plate is squeezed and deformed synchronously. The through rod passes through and is fixedly installed inside the torsion plate. The deformation of the torsion plate is reset to drive the through rod to move left and right, and the through rod drives the transmission plate to move synchronously. The top back of the transmission plate is hinged to the front face of the through rod. The transmission plate drives the rubber wheel to slide synchronously along the inclined surface of the swing plate. The rubber wheel starts to rotate due to the friction resistance generated when it contacts the swing plate. The front face of the rubber wheel is rotatably installed on the back face of the transmission plate, and the outer wall of the rubber wheel contacts the inclined surface of the swing plate. When the rubber wheel rotates, the lifting efficiency of the attachments on the inclined surface of the swing plate is improved.

The top of the vertical rod is fixedly installed at the bottom of the heating ring. The heating ring drives the vertical rod to move up and down, and the vertical rod drives the screening plate to move up and down. The top edge of the screening plate is fixedly installed at the bottom of the vertical rod. The screening plate screens the powder residue, extracts the remaining efficacy of the medicine while blocking and filtering the residue. The outer wall of the thin circular plate is fixedly installed on the inner side of the outer wall of the vertical rod. The vertical rod drives the thin circular plate to move synchronously, and the thin circular plate blocks the medicine residue.

[0013] According to the above technical solution, the screening and separating device further includes a limiting ring, a lead screw, a rotating plate and a hook-shaped ball. The bottom of the limiting ring is fixedly installed at the center of the top of the screening plate. The screening plate drives the limiting ring to move synchronously. The bottom of the lead screw penetrates and is rotatably installed at the bottom of the inner wall of the separation barrel, and the lead screw is located inside the limiting ring. When the limiting ring slides up and down along the outer wall of the lead screw, the lead screw is forced to rotate by the restriction of the spiral groove on the outer wall of the lead screw. The right side of the rotating plate is fixedly installed on the left side of the outer wall of the lead screw. When the lead screw rotates, it drives the rotating plate to rotate synchronously. The rotating plate drives the hook-shaped ball to rotate synchronously. The bottom of the hook-shaped ball is fixedly installed on the top of the rotating plate, and the inner wall of the screening hole of the screening plate is in contact with the arc surface of the hook-shaped ball. The rotating plate drives the hook-shaped ball to rotate synchronously. When the hook-shaped ball rotates, it cleans the inner wall of the screening hole of the screening plate through the arc surface.

When the hook-shaped ball 77 rotates, the inner wall of the screening hole of the screening plate 72 is cleaned through the arc surface.

[0031] During use, when the electric telescopic rotating column 51 rotates, it restricts the cross bar 61 through the arc groove, enabling the cross bar 61 to move up and down. The cross bar 61 drives the heating ring 62 to slide up and down along the inner wall of the separating barrel 2, thereby expanding the heating range of the heating ring 62, improving the heating uniformity of the heating ring 62 for the material, accelerating the reaction speed of the material in the treatment liquid, and enhancing the detection efficiency. At the same time, the heating ring 62 scrapes off some of the powder adhering to the inner wall of the separating barrel 2 to prevent the powder from adhering and curing for a long time, increasing the possibility of mixing with different varieties of materials in the later stage. The heating ring 62 drives the swing plate 63 to move synchronously. The swing plate 63 swings in the opposite direction to the movement of the heating ring 62 due to the resistance of the separating liquid, and the liquid is centered and aggregated through the swing plate 63, thereby improving the separation effect on the powder and preventing the powder at the edge from being difficult to mix with the separating liquid in time. When the swing plate 63 swings, it squeezes the torsion piece 64 to deform synchronously. The elasticity of the torsion piece 64 enables the swing plate 63 to reset in time. At the same time, the deformation and reset of the torsion piece 64 drive the through rod 65 to move left and right, and the through rod 65 drives the transmission plate 66 to move synchronously. The transmission plate 66 drives the rubber wheel 67 to slide synchronously along the inclined surface of the swing plate 63. The rubber wheel 67 starts to rotate due to the frictional resistance generated when it contacts the swing plate 63. When the rubber wheel 67 rotates, it improves the lifting efficiency of the attachments on the inclined surface of the swing plate 63, avoiding the gravity of the attachments on the swing plate 63 being too large, reducing the swing amplitude of the swing plate 63, and thus reducing the centering effect on the separating liquid.

[0032] The heating ring 62 drives the vertical rod 71 to move up and down, and the vertical rod 71 drives the sieve plate 72 to move up and down. The sieve plate 72 sieves the powder residue, extracts the remaining efficacy of the medicine, and at the same time blocks and filters the residue to prevent the detection liquid dripping out of the drip 21 from carrying the residue; the vertical rod 71 drives the thin circular plate 73 to move synchronously, and the thin circular plate 73 blocks the drug residue to prevent the inner wall of the separation barrel 2 from being eroded by the medicine and shortening its service life; the sieve plate 72 drives the limiting ring 74 to move synchronously, and when the limiting ring 74 slides up and down along the outer wall of the screw rod 75, the screw rod 75 is restricted by the spiral groove on the outer wall of the screw rod 75 to 75 promotes rotational force. When the screw rod 75 rotates, it drives the rotating plate 76 to rotate synchronously. The rotating plate 76 drives the hook ball 77 to rotate synchronously. When the hook ball 77 rotates, it contacts the inner wall of the sieve plate 72 through the arc surface. The resistance force causes the hook ball 77 to deform to avoid affecting the normal rotation of the sieve plate 72. At the same time, the arc surface of the hook ball 77 cleans the inner wall of the sieve hole of the sieve plate 72 to avoid the adhesion of residues when the inner wall of the sieve hole of the sieve plate 72 is sieved when the material is sieved, and the sieve hole of the sieve plate 72 is avoided to be blocked. At the same time, the flow aperture of the dripping 21 is prevented from being blocked, and the speed of dripping out the drug extract from the dripping 21 is prevented from slowing down.
