[0002] When testing some foods, there is a need to freeze-dry and crush the substance, then add different reagents to the crushed freeze-dried powder, and then detect it through the corresponding detection device. For example, to detect the sodium nitrite content of processed foods such as sausages and ham sausages, it is necessary to crush the food to form particles of a certain particle size and weight, freeze-dry it, and then crush it into powder, then add reagents and shake it for testing. However, when batch testing is required, although some detection devices or shaking devices can achieve multi-test tube addition and shaking, the number of test tubes that can be processed at one time is limited, and freeze-drying requires a certain waiting time. Therefore, the freeze-dried particles after freeze-drying are often temporarily stored in the prior art. When testing, a certain amount of freeze-dried particles are taken according to the dosage, crushed into powder together, and then weighed and added to test tubes and other test containers one by one.

[0022] like Figure 1-6As shown, the present invention provides a food testing device that is convenient for quick mixing, including a shaking testing device and a support structure 8. The shaking testing device includes a testing module 1 and a shaking module 2, which belongs to the existing device structure. The support structure 8 is equipped with a powder box module 6, a feeding mechanism 7, a mixing mechanism 3, a pressing and crushing mechanism 5, a discharging mechanism 4 and a power device 9. The powder box module 6 is provided with a pressed powder molding box 601 for accommodating freeze-dried particles and a powder box bottom plate 602. The pressed powder molding box 601 is slidably arranged on the powder box bottom plate 602 and is in contact with the top surface of the powder box bottom plate 602. The front part of the powder box bottom plate 602 has a front end powder discharge area 603 opposite to the detection test tube 203 in the shaking module 2. The discharge of the feeding mechanism 7 is The material end is arranged at the top of the initial position of the compressed powder molding box 601 and is open forward. The material sparging mechanism 3 includes a material sparging rotating member 301, a material sparging plate 304 and a material sparging connecting rod 303 located above the powder box module 6. One end of the material sparging connecting rod 303 is hinged to the outer edge of the material sparging rotating member 301 and the other end is hinged to the material sparging plate 304. When the bottom of the material sparging plate 304 is attached to the top surface of the compressed powder molding box 601, the material sparging connecting rod 303 pushes the material sparging plate 304 toward the material discharge end. 04 mixes the freeze-dried particles on the top and pushes the excess freeze-dried particles into the opening at the discharge end; the power device 9 is respectively connected to the mixing rotating member 301 and the discharge mechanism 4 through a transmission mechanism, thereby driving the mixing rotating member 301 and the discharge mechanism 4 to operate in coordination, the pressing and crushing mechanism 5 includes a pressing module and a cam plate 502, the pressing module is located above the powder box module 6 and is connected and installed with the support structure 8 through an elastic telescopic frame 508, the cam plate 502 is fixedly connected to the mixing rotating member 301 and a crushing pressure rod 501 is installed on the inner side, the cam plate 502 rotates and squeezes the pressing module horizontally to the pressing position and is located directly above the compressed powder molding box 601 at this position, the crushing pressure rod 501 is used to squeeze the pressing module downward to crush the freeze-dried particles in the compressed powder molding box 601 into powder, and the discharge mechanism 4 is used to drive the compressed powder molding box 601 to move forward to the front powder discharge area 603 to output powder after the pressing module is reset and then reset.

[0023] The compressed powder molding box 601 is provided with a plurality of particle receiving holes that can only accommodate one freeze-dried particle, the horizontal cross-section of the particle receiving hole is larger than the particle size of the freeze-dried particle, the discharge port of the front end powder discharge area 603 corresponds one-to-one with the particle receiving hole and at the same time corresponds one-to-one with the opening of the test tube below, the rear side of the material leveling plate 304 is provided with a plurality of material dividing comb teeth 306, the spacing between adjacent material dividing comb teeth 306 is larger than the freeze-dried particle but smaller than the particle receiving hole, and the gap between the material dividing comb teeth 306 corresponds to the position of the particle receiving hole in the front-to-back direction. When the freeze-dried particles in the particle receiving hole are simultaneously crushed into powder by the material pressing module, the compressed powder molding box 601 is pushed to the front end powder discharge area 603 under the action of the discharge mechanism 4, and when the powder discharge door plate 604 closed below the front end powder discharge area 603 is opened, the freeze-dried powder in the particle receiving hole falls into the corresponding test tube. This means that the solution does not need to grind, weigh and add each freeze-dried particle one by one, but can crush each freeze-dried particle into powder and input it into the corresponding test tube, and the amount added to each test tube is equal to the set mass of the freeze-dried particles.

[0024] The shaking module 2 includes a shaker 201, a test tube rack 202, and detection test tubes 203 correspondingly inserted into the respective sockets of the test tube rack 202. The detection test tubes 203 are inserted into the mounting groove of the shaker 201 along with the test tube rack 202 as a whole, and the shaking base drives the test tube rack 202 to shake as a whole in the mounting groove to achieve the shaking of the substances in the test tubes, and finally the detection module 1 performs sampling and detection on the mixed liquid after the shaking in each test tube.

[0025] The material leveling connecting rod 303 is hinged to the material leveling rotating member 301 through a reset shaft 305. When the reset shaft 305 is in a natural state, the angle between the line from the rotation center of the material leveling rotating member 301 to the reset shaft and the material leveling connecting rod 303 is not less than ninety degrees. When the material leveling plate 304 contacts the top surface of the powder molding box 601, one end of the material leveling connecting rod 303 is downwardly connected to the front side of the material leveling plate 304 through a reset shaft 307. When the reset shaft 307 is in a natural state, the bottom surface of the material leveling plate 304 is consistent with the direction of the line from the rotation center of the material leveling rotating member 301 to the reset shaft. In this way, when the material mixing rotating member 301 located in front of the material mixing plate 304 rotates counterclockwise from back to front, the bottom surface of the material mixing plate 304 can be in contact with the top surface of the compressed powder molding box 601, and then the excess freeze-dried particles can be pushed to the discharge end of the rear feeding mechanism 7 through the material mixing connecting rod 303. When the reset shaft 1 305 passes the position closest to the discharge end, the material mixing connecting rod 303 will slide forward with the material mixing rotating member 301, and finally detach from the front side of the compressed powder molding box 601, and the reset shaft 1 305 and the reset shaft 2 307 will return to their natural state under the action of their respective torsion springs.

[0026] The reset shaft 1 305 includes a connecting shaft 1 and a torsion spring 1 sleeved on the connecting shaft 1.

The connecting shaft 2 is fixedly connected to the front side of the material leveling plate 304, and the material leveling connecting rod 303 is connected to the connecting shaft through the torsion spring 1. Therefore, the two parts connected by the reset shaft will rotate when receiving a sufficiently large force, but the two parts will return to the initial relative position after the force is lost.

[0027] The feeding mechanism 7 includes a storage hopper 701, in which a number of freeze-dried particles are stored. The bottom of the storage hopper 701 extends to the powder box module 6 through a feeding channel 702 that discharges materials downwardly in an inclined manner. The lower end of the feeding channel 702 is provided with a material mixing and receiving section 703 extending horizontally. The front side of the material mixing and receiving section 703 is provided with an opening for feeding. The end where the opening is located is the discharge end of the feeding mechanism 7, and allows the material mixing plate 304 to push the freeze-dried particles in. A feeding door 705 is provided at the opening of the material mixing and receiving section 703. The support structure 8 is provided with side baffles located on the left and right sides of the discharge end to prevent the freeze-dried particles that enter the top of the compressed powder molding box 601 from falling from the side. A servo for opening the feeding door 705 is installed on the side baffle. The feeding door 705 is hinged in the opening through a rotating shaft at the top and can only be opened to the inside of the opening. After the servo opens the feed door 705 inward, the freeze-dried particles in the storage hopper 701 can be released to the top of the compressed powder molding box 601. After the release stops, the mixing plate 304 can push the freeze-dried particles into the mixing storage section 703 during the mixing stage. When the mixing plate 304 is pulled out, the feed door 705 that is reset downward inward will block the excess freeze-dried particles and prevent the latter from rolling out to the top of the compressed powder molding box 601 again.

[0029] The pressing module includes a pressing module shell 503, the top of which is open and provided with a pressing module top plate 504 located in the middle, the pressing module top plate 504 is connected to a pressing head 506 slidably arranged inside the pressing module shell 503 through a tension spring 505, the left and right sides of the top opening are not covered by the pressing module top plate 504, a pressure rod groove 507 is provided on the front side of the uncovered top opening part, the protruding end of the crushing pressure rod 501 enters from the uncovered top opening part to press down the pressure head 506, the pressure rod groove 507 is used to allow the crushing pressure rod 501 to be pressed down with the rotation of the material leveling rotating member 301 and to disengage through the pressure rod groove 507, after the crushing pressure rod 501 is disengaged, the tension spring 505 drives the pressure head 506 to reset. The pressing head 506 is provided with a punch head which corresponds to each particle receiving hole below and has clearance fit.

The intermittent transmission mechanism includes an incomplete gear 401, a driven gear 402 and a limit turntable structure 406. The limit turntable structure 406 includes a notched disc and a fan-shaped structure. The notched disc is coaxially fixedly connected to the driven gear 402, and the fan-shaped structure is coaxially fixedly connected to the incomplete gear 401. The incomplete gear 401 can mesh with the driven gear 402 in the discharging stage, and the arc-shaped notch portion of the notch disk fits with the outer arc section 5022 of the fan-shaped structure outside the discharging stage. In this way, except for the discharging stage, the discharging mechanism 4 is not driven by the power device 9, and in the discharging stage, the discharging mechanism 4 runs with the power device 9 to push the powder pressing box 601 to push the crushed freeze-dried powder to the front powder discharging area 603 to discharge from the discharging port.

When the pressed powder molding box 601 moves forward to allow the cylindrical heads 607 to be embedded in the grooves, the cylindrical heads 607 push the door opening drive rods 605, and then open the powder discharge door plate 604, so that the powder discharge door plate 604 can be opened to discharge the material only when the particle receiving hole is close to the discharge port, so as to avoid premature leakage of freeze-dried powder. When there are two rows of test tubes, the powder outlet door plates 604 also have two and are arranged front and back. The door opening drive rod 605 is arranged on the front powder outlet door plate 604. The left and right sides of the front and rear powder outlet door plates 604 are connected by a horizontal connecting rod. The horizontal connecting rod, the two powder outlet door plates 604 and the front powder outlet area 603 as a frame form a parallelogram connecting rod mechanism. In this way, the front and rear powder outlet door plates 604 can be opened at the same time by the door opening drive rod 605, and the problem of the particle receiving hole on the front side leaking the freeze-dried powder from the discharge port on the rear side in advance can be avoided. A limit baffle plate 606 is also fixed at the front end of the front powder outlet area 603 to prevent the powder pressing molding box 601 from exceeding the limit and scattering part of the powder to the outside.
