[0002] With the improvement of people's living standards and health awareness, how to improve food quality, reduce the residue of harmful substances in food, and ensure the quality and safety of food is an important task in the current food production and processing industry. During the testing process, food needs to be fully crushed and stirred to make samples for easy testing.

[0003] The publication number is CN220194535U, which discloses a special sample preparation and stirring device for food inspection and testing, and relates to the technical field of stirring equipment. The sample preparation and stirring device includes a device body, a servo motor is arranged on the top of the device body, a stirring barrel is arranged inside the device body, and an oscillation component is arranged inside the stirring barrel; the oscillation component includes a transmission rod, and the transmission rod is connected to the output shaft of the servo motor. The sample preparation and stirring device places the stirring barrel inside the device body, starts the servo motor, and makes the transmission rod rotate under the action of the servo motor, so that the bevel gear 1 rotates, cooperates with the fixed rod, and makes the stirring plate rotate. When the bevel gear 1 rotates, the bevel gear 2 rotates, cooperates with the rotating rod, so that the rotating rod drives the cam 1 to rotate, so that the cam 1 squeezes the force block, so that the pressure rod moves, so that the pressure block moves, so that the possibility of upper and lower stratification during food stirring is reduced, and the stirring effect of the device is improved.

[0004] In the above patent, a rotating rod is used to drive a cam to rotate, so that the cam squeezes the force-bearing block, so that the pressure rod moves, and the pressure block moves up and down into layers. However, structures such as the bevel gear in the device are exposed in the mixing barrel. During the mixing process, the gear contacts the food, which can easily cause the food to block the gear tooth operation and affect the rotation and linkage effect. In addition, the mixing device needs to be compatible with the mixing barrel and cannot be used in other containers for mixing operations. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a sample preparation and stirring device specifically for food inspection and testing, which solves the problems raised in the above-mentioned background technology.

[0007] Furthermore, side grooves are provided on the left and right sides of the outer surface of the rotating shaft, a screw rod is rotatably connected inside the side groove, a gear is fixed at the bottom of the outer surface of the screw rod, a screw block is threadedly connected to the outer surface of the screw rod, and the two screw blocks are both in contact with the inner surface of the lifting cylinder, and a plurality of tooth grooves are provided on the outer surface of the middle column, and the middle column is meshed and connected with two gears through the tooth grooves.

[0008] Furthermore, handles are fixed on the left and right sides of the casing.

[0009] Furthermore, the inner upper surface of the inner cavity is in contact with the upper surface of the turntable.

[0010] Furthermore, the outer surface of the stop block and the lower surface of the chassis are both provided with a rubber layer.

[0011] The beneficial effects of the special sample preparation and stirring device for food inspection and detection of the present invention are:

[0012] The present invention controls the operation of the motor to drive the rotating shaft and the lifting cylinder to rotate outside the middle column. The middle column will not rotate with the rotation of the rotating shaft. Therefore, when the lifting cylinder and the stirring blade rotate to stir the food sample, the gear is meshed with the tooth groove on the outer surface of the middle column to rotate the gear and the screw.

The bottom end of the output shaft of the motor 4 passes through the bottom of the housing 3 and is fixed with a rotating shaft 5. A lifting cylinder 6 is sleeved on the outer surface of the rotating shaft 5. A plurality of stirring blades 7 are fixed below the outer surface of the lifting cylinder 6. An inner cavity 8 is opened at the bottom of the rotating shaft 5. A turntable 9 is movably connected inside the inner cavity 8. The bottom of the rotating shaft 5 A chassis 15 is rotatably connected, and a middle column 10 is rotatably connected at the center of the lower surface of the turntable 9. The bottom end of the middle column 10 penetrates into the inside of the chassis 15 and is rotatably connected to two connecting rods 16. The opposite ends of the two connecting rods 16 are rotatably connected to telescopic strips 17. The telescopic strip 17 is internally threadedly connected with a second screw 18. The end of the second screw 18 away from the telescopic strip 17 is rotatably connected to a stop block 19. The distance between the stop block 19 and the chassis 15 can be adjusted by rotating the second screw 18. When the mixer body 1 is used for stirring in other containers, it is adapted to the container to improve the adaptability.

[0021] like Figure 3 As shown, the left and right sides of the outer surface of the rotating shaft 5 are provided with side grooves 11, a screw 12 is rotatably connected inside the side groove 11, a gear 13 is fixed at the bottom of the outer surface of the screw 12, a screw block 14 is threadedly connected to the outer surface of the screw 12, and the two screw blocks 14 are both in contact with the inner surface of the lifting cylinder 6, and a plurality of tooth grooves 20 are provided on the outer surface of the middle column 10, and the middle column 10 is meshed and connected with the two gears 13 through the tooth grooves 20;

[0022] The left and right sides of the housing 3 are both fixed with handles 21, and the mixer body 1 can be moved and stirred conveniently by holding the handles 21;

[0023] The inner upper surface of the inner cavity 8 fits with the upper surface of the turntable 9, and the rotating shaft 5 presses the turntable 9 through the inner cavity 8, so that the middle column 10 descends, and the extension bar 17 screw 2 18 and the stop block 19 move through the push connecting rod 16, and the stop block 19 contacts and fits with the inner wall of the mixing barrel 2;

[0024] The outer surface of the stopper 19 and the lower surface of the chassis 15 are both provided with a rubber layer to increase the friction between the stopper 19, the chassis 15 and the inner wall of the mixing barrel 2, so that when the motor 4 drives the rotating shaft 5 and the lifting cylinder 6 to rotate outside the middle column 10, the middle column 10 will not rotate with the rotation of the rotating shaft 5. Therefore, when the lifting cylinder 6 and the stirring blade 7 rotate to stir the food sample, the gear 13 is meshed with the tooth groove 20 on the outer surface of the middle column 10, so that the gear 13 and the screw 12 rotate. After the screw 12 rotates, the screw block 14 drives the lifting cylinder 6 and the stirring blade 7 to move up and down, thereby reducing the possibility of upper and lower stratification during food stirring, thereby improving the stirring effect of the device.
