[0002] With the continuous development of society and the continuous advancement of science and technology, the technology related to food processing is also constantly improving. During the production and processing of powdered food, it is necessary to store it in a storage box for a long time. During the storage of food, its water content will change according to the temperature and humidity of the environment. The higher the humidity, the higher the water content, which is easy to cause the powdered food to agglomerate. Therefore, it is necessary to detect the moisture degree of the food in the storage box to ensure the safe storage of the food and avoid the food from being damaged by moisture and mold.

[0028] A rotating shaft 5 is rotatably mounted on the mounting block 1, a collecting frame 4 is fixedly connected to the rotating shaft 5, a partition assembly is arranged on the collecting frame 4, the partition assembly comprises a plurality of inclined plates 3, a surface of each inclined plate 3 is fixedly connected to the inner wall of the collecting frame 4, a collecting groove 30 is provided in the collecting frame 4, a plurality of sensing probe blocks 27 are fixedly arranged on the inner wall of one side of the collecting groove 30, a humidity sensor is installed on the surface of one side of the collecting frame 4 (the humidity sensor is a prior art, and its working principle is not described in detail).

[0029] A sliding rod 22 is fixedly connected to the surface of one side of each push plate 28, and each sliding rod 22 is slidably connected to the sampling tube 12. Multiple sliding rods 22 are connected through a bending plate 23. A threaded rod 24 is threadedly connected to the bracket 9. The threaded rod 24 and the bending plate 23 are rotatably connected. The threaded rod 24 is manually rotated. During the process of the threaded connection between the threaded rod 24 and the bracket 9, the bending plate 23 will rotate relative to the threaded rod 24, and the bending plate 23 moves toward the direction close to the sampling tube 12. At the same time, the sliding rod 22 slides relative to the sampling tube 12. During the movement of the push plate 28, the sample of powdered food inside the sampling slot 16 can be pushed out.

[0030] A second arc-shaped opening is provided on the bracket 9, and a second slider 15 is slidably connected in the second arc-shaped opening. A telescopic rod 20 is fixedly connected to the lower surface of the second slider 15. The telescopic end of the telescopic rod 20 is fixedly connected to the first slider 21. The hydraulic cylinder drives the cross block 10 to move vertically downward. Since the first slider 21 cannot slide relative to the cross block 10 in the vertical direction, the second slider 15 cannot slide relative to the bracket 9 in the vertical direction. The first slider 21 will move downward together with the cross block 10, and the telescopic rod 20 will be stretched and deformed.

[0031] The bracket 9 is rotatably connected with a rotating rod 8 having a T-shaped cross section, a torsion spring 14 is sleeved on the rotating rod 8, one end of the torsion spring 14 is fixedly connected to the rotating rod 8, and the other end of the torsion spring 14 is fixedly connected to the bracket 9, a second slider 15 is fixedly connected to the rotating rod 8, an insertion shaft 17 is slidably connected to the rotating rod 8, a first spring 19 is sleeved on the insertion shaft 17, one end of the first spring 19 is fixedly connected to the insertion shaft 17, and the other end of the first spring 19 is fixedly connected to the rotating rod 8, and a plurality of card slots 18 are provided on one side surface of the mounting block 1, The slots 18 are evenly and equidistantly arranged, and the rotating rod 8 and the bracket 9 are manually rotated relative to each other, and the torsion spring 14 is deformed. When the rubber pad on the surface of the arc cover 11 is in close contact with the outer surface of the sampling tube 12 and multiple sampling slots 16 are sealed and blocked at the same time, the upper end of the plug-in shaft 17 is located directly below a slot 18. Under the elastic force of the first spring 19, the plug-in shaft 17 will move upward and slide relative to the rotating rod 8 until the upper end of the plug-in shaft 17 is engaged with the slot 18, which can prevent the subsequent arc cover 11 from moving at will.

[0032] A saw gear 25 is fixedly connected to the rotating shaft 5, and a sliding groove is provided on one side surface of the mounting block 1. A moving block 13 is slidably connected inside the sliding groove. A fixing sleeve 26 with a U-shaped cross section is fixedly connected to the lower surface of the moving block 13. A second spring 2 is provided inside the sliding groove. One end of the second spring 2 is fixedly connected to the upper inner wall of the sliding groove, and the other end of the second spring 2 is fixedly connected to the moving block 13, pushing the moving block 13 upward. During the upward movement of the moving block 13 in the sliding groove, the second spring 2 will be deformed, and the fixing sleeve 26 will move up at the same time. In the initial state, the U-shaped fixing sleeve 26 is sleeved on the outer side of a saw tooth of the saw gear 25, which can effectively prevent the saw gear 25 from rotating. After the fixing sleeve 26 moves up, it will be disengaged from the saw gear 25, that is, the limit on the saw gear 25 is released.

[0033] A servo motor is fixedly mounted on the mounting block 1, and a driving end of the servo motor is fixedly connected to one end of a reciprocating screw rod 6. An opening for horizontal movement of a bracket 9 is provided on the mounting block 1. A mounting frame 7 having an L-shaped cross section is fixedly connected to the back of the mounting block 1. A plurality of mounting holes 29 are provided on the mounting frame 7. A plurality of bolts are passed through the plurality of mounting holes 29 and are threadedly connected to the mounting position, so as to fix the mounting frame 7 at a specific position for stable use of the equipment.

[0034] In the present invention, the equipment is disinfected before use. Then, under the driving action of the servo motor, the reciprocating screw 6 and the mounting block 1 rotate relative to each other, and the bracket 9 moves along the reciprocating screw 6 until the sampling tube 12 moves to the top of the powdered food to be detected. Then, the rotating rod 8 and the bracket 9 are manually rotated relative to each other, the torsion spring 14 is deformed, and the second slider 15 rotates together with the rotating rod 8, which drives the telescopic rod 20 to rotate together. Under the transmission action of the telescopic rod 20, the first slider 21 and the arc-shaped cover plate 11 rotate at the same time. When the rubber pad on the surface of the arc-shaped cover plate 11 is tightly attached to the outer surface of the sampling tube 12 and multiple sampling slots 16 are sealed and blocked at the same time, the upper end of the plug shaft 17 is located directly below a slot 18 at this time. Under the elastic force of the first spring 19, the plug shaft 17 moves upward and slides relative to the rotating rod 8 until the upper end of the plug shaft 17 is engaged with the slot 18, which can prevent the subsequent arc-shaped cover plate 11 from moving at will.

[0035] After that, the hydraulic cylinder drives the cross block 10 to move vertically downward. Since the first slider 21 cannot slide relative to the cross block 10 in the vertical direction, and the second slider 15 cannot slide relative to the bracket 9 in the vertical direction, the first slider 21 will move downward with the cross block 10, and the telescopic rod 20 will be stretched and deformed. After the sampling tube 12 moves downward with the cross block 10, it will be inserted into the interior of the powdered food to be tested directly below. When the sampling tube 12 is inserted into the powdered food to be tested to a sufficient depth, the hydraulic cylinder stops working, and then the insertion shaft 17 is pulled downward, and the first elastic The spring 19 is deformed, and under the elastic force of the torsion spring 14, the rotating rod 8 rotates. Under the transmission action of the second slider 15, the telescopic rod 20 and the first slider 21, the arc cover 11 rotates at the same time and is staggered with each sampling slot 16. At this time, the sampling slot 16 is exposed to the outside, and the powdered food to be tested at each depth will automatically fall into the sampling slot 16 of the corresponding height. Then, the rotating rod 8 is rotated again, and the upper end of the plug shaft 17 is engaged with the card slot 18, so that the arc cover 11 can seal and block multiple sampling slots 16 again.

[0036] Then the hydraulic cylinder drives the cross block 10 to move upward until the sampling tube 12 is completely removed from the powdered food to be tested. Similarly, the plug shaft 17 is disengaged from the card slot 18 again, and the arc cover plate 11 is staggered with multiple sampling slots 16. At this time, the sampling tube 12 is located on the opposite side of the collecting frame 4. Then the servo motor drives the reciprocating screw 6 to rotate, and the bracket 9 moves along the reciprocating screw 6 until the surfaces of each inclined plate 3 are respectively in contact with the surfaces of each sampling tube 12 and the inner walls of each sampling slot 16. Finally, the threaded rod 24 is manually rotated. During the process of threaded connection between the threaded rod 24 and the bracket 9, the bending plate 23 cannot slide relative to the threaded rod 24 along the axial direction of the threaded rod 24. The bending plate 23 will The push plates 28 rotate relative to the threaded rod 24, and the bent plate 23 moves toward the sampling tube 12. The slide bar 22 slides relative to the sampling tube 12 at the same time. In the initial state, the surfaces of each push plate 28 are respectively in contact with the inner walls of the corresponding sampling grooves 16. During the movement of the push plates 28, the samples of powdered food in the sampling grooves 16 can be pushed onto the corresponding inclined plates 3. The samples of powdered food slide along the inclined plates 3 to the inside of the collecting groove 30 and contact the sensor probe block 27. The humidity of each sample can be quickly detected by the humidity sensor, and the humidity of the powdered food at different depths can be detected. The humidity detection effect of the powdered food is better, which is beneficial to the humidity detection of the food.

[0037] The moving block 13 is pushed upward. During the process of the moving block 13 moving upward in the slide groove, the second spring 2 will be deformed, and the fixing sleeve 26 will move upward at the same time. In the initial state, the U-shaped fixing sleeve 26 is sleeved on the outer side of a saw tooth of the saw gear 25, which can effectively prevent the saw gear 25 from rotating. After the fixing sleeve 26 moves upward, it will be disengaged from the saw gear 25, that is, the limit on the saw gear 25 is released, and then the rotating shaft 5 is rotated, and the collecting frame 4 will be deflected together with the rotating shaft 5. After the collecting frame 4 is deflected downward, the various samples inside the collecting groove 30 will automatically fall out under the action of gravity, and the speed of removing the samples is faster, which is beneficial to the use of humidity monitoring equipment.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
