The embodiment of the utility model provides a milk quality analysis device which can be used for carrying out quality analysis on milk such as goat milk, horse milk, camel milk and the like.

As shown in fig. 1 and 2, the kit comprises a driving box 100, a bearing plate 200, a kit 300 and a control system (not shown in the drawings), wherein the driving box 100 is provided with a driving motor 120, driving can be realized, the bearing plate 200 is used for bearing milk sample slides or test papers, reagents for analysis are contained in the kit 300, and the control system can realize automatic control of each component.

As shown in fig. 1 and 2, the driving case 100 has a case structure and may be formed in a substantially rectangular parallelepiped shape. The driving box 100 is rotatably connected with the screw rod 110 and is driven by the driving motor 120, that is, one end of the screw rod 110 may extend out of the driving box 100 to be in transmission connection with the driving motor 120.

As shown in fig. 1 and 2, the top wall of the driving box 100 is provided with a guide hole 130, the guide hole 130 and the screw 110 both extend along the length direction of the driving box 100, and the screw 110 is located right under the guide hole 130. When the screw 110 rotates with the driving motor 120, movement of the screw-engaging part thereon in the length direction of the driving case 100 can be achieved.

As shown in fig. 1, 2 and 3, the loading plate 200 extends along the length direction of the driving box 100, the mounting plate 210 is provided under the loading plate 200, the mounting plate 210 is provided with a screw hole 211, the mounting plate 210 passes through the guide hole 130 and is screwed with the screw rod 110 through the screw hole 211, and thus the entire loading plate 200 can move along the length direction of the driving box 100 under the rotation of the screw rod 110.

As shown in fig. 1 and 3, the upper surface of the carrying plate 200 is provided with a plurality of placement positions 220, the plurality of placement positions 220 are uniformly spaced along the length direction of the driving box 100, the placement positions 220 are used for placing milk samples, and when the carrying plate 200 moves along the length direction of the driving box 100, each placement position 220 also moves along the length direction of the driving box 100.

As shown in fig. 1 and 2, the kit 300 is disposed above the carrier plate 200, and the kit 300 may be mounted above the carrier plate 200 by a bracket structure. A dropper 310 is arranged below the kit 300, the dropper 310 is arranged above the placement position 220, and the dropper 310 is provided with a pulse valve (not shown in the figure), when the pulse valve is opened, reagents in the kit 300 can drop out of the dropper 310 and fall onto a milk sample at the placement position 220, so that the reaction of the reagents and the milk sample is realized.

The driving motor 120 and the pulse valve are electrically connected with a control system, so that the driving motor 120 and the pulse valve are automatically controlled. When the driving motor 120 drives the milk sample on the carrying plate 200 to move to the lower part of the dropper 310, the control system opens the one-time pulse valve, and the reagent can be dripped on the milk sample.

It should be noted that, each time the driving motor 120 is started, the distance that the placement bit 220 can move is determined by the number of turns of the driving motor 120, so the moving distance of the placement bit 220 can be controlled by controlling the number of turns of the driving motor 120. For example, assuming that the spacing between two adjacent placements 220 is achieved by one revolution of the drive motor 120, the control system may set the drive motor 120 to rotate one revolution after each start (typically with a frequency converter), and then stop, such that the distance traveled by the placements 220 (i.e., the spacing between the two placements 220) is equal each time the drive motor 120 is started. Thus, when the previous place 220 is located below the drip tube 310, the drive motor 120 is started once, and the next place 220 can be moved below the drip tube 310 to drop the reagent onto the milk sample. Such settings for the drive motor 120 are well known to those skilled in the art and will not be described in detail herein.

When the device is used, an operator places a plurality of milk sample slides or test papers on the placing positions 220, turns on the driving motor 120 to enable the placing positions 220 to move to the lower side of the dropper 310 one by one, the control system can control the pulse valve of the dropper 310 to be opened once, and the reagent is dripped from the dropper 310 to the milk sample slides or test papers, so that the reagent reacts with the milk samples, and then the quality analysis result of the milk samples can be obtained by observing the color change after the reaction.

Compared with the prior art, the milk quality analysis device can be used for placing a plurality of milk samples, so that the quality analysis of the milk samples is realized, repeated operation of operators is reduced, and the analysis efficiency of the milk samples is improved.

In some embodiments, as shown in fig. 3, the carrier plate 200 includes a support plate 230 and a moving plate 240, the mounting plate 210 is mounted below the support plate 230, the moving plate 240 is detachably connected above the support plate 230, and a plurality of placement sites 220 are disposed on the moving plate 240. That is, the movable plate 240 may be removable from the support plate 230 to facilitate placement of the milk sample on the movable plate 240 by an operator. After the milk sample is placed, the moving plate 240 is placed on the support plate 230. This configuration also facilitates the overall movement of multiple milk samples (e.g., some milk samples may need to be placed in the culture chamber for analysis), facilitates the overall operation, and avoids a single operation.

In some embodiments, as shown in fig. 3, the upper surface of the support plate 230 is provided with a limiting hole 231, the lower surface of the moving plate 240 is provided with a limiting shaft 241, and the limiting shaft 241 is inserted into the limiting hole 231 in a matched manner, so that the moving plate 240 and the support plate 230 are kept fixed in the horizontal direction, and the moving plate 240 and the support plate 230 are prevented from being misplaced in the starting process of the driving motor 120. Generally, the number of the limiting holes 231 and the limiting shafts 241 is two.

In some embodiments, sample clamping plates (not shown) are arranged on two sides of the placement position 220, and the sample clamping plates can be rotatably connected to the placement position 220 through torsion springs, so that milk sample slides or milk sample test papers can be firmly clamped.

In some embodiments, the number of the drip tubes 310 is plural, and the plurality of drip tubes 310 are arranged at intervals in the width direction of the drive cassette 100, so that the reagent can be dripped at plural positions at one time. As shown in fig. 4, a plurality of sets of placement positions 220 are disposed on the carrier 200, the sets of placement positions 220 are disposed at intervals along the width direction of the driving box 100 and correspond to the plurality of droppers 310 one by one, and the plurality of placement positions 220 in each set of placement positions 220 are disposed at intervals along the length direction of the driving box 100. In this configuration, there are more places 220 on the carrier plate 200, more milk samples are analyzed at a time, and the analysis efficiency is higher.

In some embodiments, the height difference between the lower end of the dropper 310 and the placement position 220 is 8mm to 12mm, which is convenient for placing the milk sample slide or test paper, and prevents the milk sample slide or test paper from colliding with the dropper 310, so as to ensure that the analysis work is performed normally.

In some embodiments, the kit 300 is provided with a level gauge, which can display how much reagent is in the kit 300, so that an operator can add reagent into the kit 300 in time.

In some embodiments, the driving motor 120 is a servo motor, which has the advantage of accurate position control, and is convenient to start and stop and convenient to control.
