[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figures 1-7 As shown, a veterinary drug testing sample preparation device includes a preparation cylinder 1, a cylinder cover 2 is movably installed on the outer side of the preparation cylinder 1 near the upper side, a scalar tube 3 is fixedly connected to the right side of the preparation cylinder 1, a stirring paddle 4 is movably installed on the upper inner side of the cylinder cover 2, a fixing ring 5 is fixedly connected to the lower side of the preparation cylinder 1 near the edge, and a feeding mechanism 6 is movably sleeved on the outer side of the fixing ring 5.

[0029] The feeding mechanism 6 includes a mechanism platform 61. The inner side of the mechanism platform 61 is movably sleeved on the outer side of the fixed ring 5. A sealing plug 62 is movably sleeved on the middle of the inner side of the inner wall of the mechanism platform 61. A first spring 63 is movably installed on the lower side of the sealing plug 62. The outer side of the sealing plug 62 is movably sleeved on the inner side of the bottom wall of the preparation cylinder 1 near the upper side. A water pump 64 is fixedly connected inside the inner wall of the mechanism platform 61. A rotating seat 65 is rotatably connected in the lower groove of the mechanism platform 61 near the left side. A rotating sleeve 68 is rotatably connected in the outer side of the rotating seat 65 near the right side. A rotating tube 66 is fixedly connected to the rear side of the rotating sleeve 68. The rotating tube 66, the mechanism platform 61 and the inner side of the water pump 64 are connected by a hose.

[0030] It should be noted that the scalar tube 3 uses the principle of communicating vessels to indicate the height of the liquid inside the preparation cylinder 1. The cylinder cover 2 contains a motor to drive the stirring paddle 4 to rotate. The first spring 63 pushes the sealing plug 62 up, so that the sealing plug 62 seals the bottom of the preparation cylinder 1 to prevent liquid leakage. The water pump 64 draws the sample from the inside of the preparation cylinder 1 through the hose and discharges it from the rotating tube 66.

[0031] like Figure 7 As shown, a third spring 69 is movably sleeved on the inner side wall of the rotating base 65, and the third spring 69 is located on the left side of the rotating sleeve 68. Several annularly distributed limiting grooves 610 are opened on the right side of the left wall of the rotating sleeve 68. The protrusion on the right side of the inner side wall of the rotating base 65 is movably sleeved on the inner side of the limiting groove 610.

[0032] It should be noted that the third spring 69 pushes the rotating sleeve 68, causing the protrusion to be stuck inside the limiting groove 610, so that the rotating seat 65 and the rotating sleeve 68 cannot rotate relative to each other. Rotating the rotating seat 65 causes the rotating seat 65 and the rotating tube 66 to rotate from the groove under the mechanism table 61. Then, pushing the rotating sleeve 68 causes the protrusion to disengage from the limiting groove 610. Rotating the rotating sleeve 68 ninety degrees causes the rotating tube 66 to stand up, resetting the rotating sleeve 68, so that the rotating sleeve 68 is fixed again.

[0033] like Figure 5 As shown, a rubber pad is fixedly connected to the upper side of the rotator 65.

[0034] It should be noted that the rubber pad is used to make the rotating tube 66 contact the horizontal surface on which the device is placed when the rotating mechanism table 61 is in the groove below the rotating tube 66, thereby fixing the rotating seat 65.

[0035] like Figure 6 As shown, a fixing component 67 is movably sleeved on the inner side wall of the mechanism platform 61 near the right rear side. The fixing component 67 includes a locking block 671. The outer side of the locking block 671 is movably sleeved on the inner side of the inner side wall of the mechanism platform 61 near the right rear side, and the outer side of the locking block 671 is movably sleeved on the inner side of the rotating tube 66 near the left side. A push groove 672 is provided on the inner side of the locking block 671. A push rod 673 is movably sleeved on the inner side of the push groove 672, and the lower surface of the push rod 673 is coplanar with the lower surface of the mechanism platform 61.

[0036] It should be noted that the locking block 671 is locked into the rotating tube 66, which fixes the rotating tube 66 and prevents it from being pulled out of the groove on the lower side of the mechanism table 61. The push rod 673 is pushed up, causing the push rod 673 to slide in the push groove 672, which causes the locking block 671 to disengage from the inside of the rotating tube 66, allowing the rotating tube 66 to be pulled out of the groove on the lower side of the mechanism table 61.

[0037] like Figure 6 As shown, a circular plate 674 is fixedly connected to the outer side of the push rod 673 near the bottom. A second spring 675 is movably installed on the outer side of the push rod 673 and the right side of the latch block 671, with the lower second spring 675 located on the upper side of the circular plate 674.

[0038] It should be noted that the second spring 675 is used to drive the push rod 673 and the locking block 671 to reset, so as to prevent the push rod 673 from being pushed and the two from failing to reset, which would affect the lower side fixation of the rotating tube 66. At the same time, it is used to stabilize the locking block 671 and prevent the locking block 671 from moving out of the rotating tube 66 on its own.

[0039] like Figure 4As shown, a number of annularly distributed balls 612 are movably sleeved on the inner side of the outer side wall of the mechanism platform 61 near the upper side. The outer side of the balls 612 is movably sleeved in the ball groove opened on the outer side of the fixed ring 5. A limiting sleeve 611 is movably sleeved on the outer side of the mechanism platform 61. A number of annularly distributed dislocation grooves 613 are opened on the inner side of the limiting sleeve 611 near the bottom.

[0040] It should be noted that in the initial state, the dislocation groove 613 and the ball 612 are misaligned, which causes the limiting sleeve 611 to fix the ball 612, making the ball 612 stuck in the ball groove and unable to move. This causes the mechanism table 61 to be fixed on the fixed ring 5. Pushing the limiting sleeve 611 up causes the dislocation groove 613 to align with the ball 612, allowing the mechanism table 61 to be removed from the fixed ring 5.

[0041] like Figure 4 As shown, a number of ring-shaped limiting rods 614 are fixedly connected to the inner side of the outer wall of the mechanism platform 61. The inner side of the limiting sleeve 611 is movably sleeved on the outer side of the limiting rods 614 through a horizontal plate near the bottom. A fourth spring 615 is movably sleeved on the outer side of each of the limiting rods 614, and the fourth spring 615 is located on the upper side of the horizontal plate.

[0042] It should be noted that the fourth spring 615 pushes down the horizontal plate, causing the limiting sleeve 611 to be unable to move upward on its own without human intervention.

[0043] The working principle of this utility model is as follows: First, the first spring 63 pushes the sealing plug 62 upward, so that the sealing plug 62 seals the bottom of the preparation cylinder 1 to prevent liquid leakage. The water pump 64 draws the sample from the inside of the preparation cylinder 1 through the hose and discharges it from the rotating tube 66. In the initial state, the dislocation groove 613 and the ball 612 are misaligned, so that the limiting sleeve 611 fixes the ball 612, causing the ball 612 to be stuck in the ball groove and unable to move, so that the mechanism table 61 is fixed on the fixing ring 5. Pushing the limiting sleeve 611 upward makes the dislocation groove 613 align with the ball 612, so that the mechanism table 61 is fixed on the fixing ring 5. The stage 61 can be removed from the fixing ring 5. By rotating the rotating base 65 and then rotating the rotating tube 66, the right end of the rotating tube 66 can face the left side of the preparation cylinder 1. Then, the water pump 64 uses the hose to draw the sample from the inside of the preparation cylinder 1 and pulls the sample out from the rotating tube 66, which facilitates the device to send the sample into the sample tube. At the same time, the limiting sleeve 611 restricts the ball 612, so that the stage 61 can be quickly installed on the preparation cylinder 1 and is easy to disassemble. This avoids the problem of the rotating base 65 causing the equipment to be difficult to clean. Finally, the third spring 69 pushes the rotating sleeve 68, causing the protrusion to be engaged. The inner side of the limiting groove 610 prevents relative rotation between the rotating seat 65 and the rotating sleeve 68. Rotating the rotating seat 65 causes the rotating seat 65 and the rotating tube 66 to rotate out of the groove on the lower side of the mechanism table 61. Then, pushing the rotating sleeve 68 causes the protrusion to disengage from the limiting groove 610. Rotating the rotating sleeve 68 ninety degrees causes the rotating tube 66 to stand up. Resetting the rotating sleeve 68 causes it to be fixed again. The locking block 671 engages with the rotating tube 66, fixing it so that the rotating tube 66 cannot be pulled out of the groove on the lower side of the mechanism table 61. Pushing the push rod 673 causes the push rod 67 to... 3. Slide within the push groove 672, causing the locking block 671 to disengage from the inner side of the rotating tube 66, allowing the rotating tube 66 to be pulled out from the lower groove of the mechanism platform 61. By rotating the rotating tube 66, the rotating tube 66 is brought to a horizontal position. Then, rotate the rotating seat 65 and use the locking block 671 to fix the rotating tube 66, so that the rotating tube 66 and the rotating seat 65 are fixed in the lower groove of the mechanism platform 61. This allows the rotating seat 65 and the rotating tube 66 to be quickly stored, avoiding the possibility of the rotating seat 65 and the rotating tube 66 being exposed and potentially colliding with other objects when stored.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
