For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] See attached Figure 1-4 , a rice moisture detection device, comprising:

[0032] A base 1 is provided with two slide grooves 2 on its upper surface; a slide seat 3 is provided on the slide groove 2 to slide with the slide groove 2, and a weighing device 4 is provided on the slide seat 3;

[0033] Two n-shaped support frames 5 are arranged on the base 1; the tops of the two n-shaped support frames 5 are connected by a connecting plate 6, and a bearing plate 7 is arranged below the connecting plate 6; the bearing plate 7 is welded to the vertical rods of the two n-shaped support frames 5, and an avoidance hole is arranged in the middle thereof;

[0034] The motor 8 is fixed on the lower surface of the connecting plate 6, and its output shaft is arranged downward and connected to a transmission shaft through a coupling;

[0035] The crushing drum 9 is located on the bearing plate 7, and its bottom plate passes through the avoidance hole and is provided with a plurality of filter holes; a stirring shaft 10 connected to the bottom of the transmission shaft is provided in the middle of the bottom of the crushing drum, and three inclined stirring blades 11 are provided on the stirring shaft 10, which can quickly crush the rice when rotating; a flange plate 26 is provided below the outer wall of the crushing drum 9, and the flange plate 26 is fixed to the bearing plate 7 by bolts, which can keep the crushing drum 9 stable during the crushing process;

[0036] The weighing frame 12 is placed on the weighing device 4 and is located below the crushing cylinder 9;

[0037] The air chamber 13 is located between the two n-shaped support frames 5 and below the load-bearing plate 7; one end of the air chamber 13 is connected to the blower and the heating box through a pipeline, and the other end is provided with multiple air outlets 14; the air outlets 14 face the weighing frame 12 and are higher than the weighing frame 12.

[0038] In this embodiment, the weighing device 4 can be an existing device for weighing, such as an electronic scale. The transmission shaft is a reciprocating screw 15, on which a truncated cone-shaped baffle plate 16 is provided; the inner wall of the crushing cylinder 9 is provided with two symmetrical limit plates 17; the edge of the baffle plate 16 is provided with a limit groove 18 corresponding to the position of the limit plate 17. When the motor 8 drives the reciprocating screw 15 to rotate, the baffle plate 16 can move up and down along the limit plate 17, repeatedly compressing and expanding the activity space of the rice crushing process, which is conducive to improving the crushing efficiency.

[0039] In addition, the weighing frame 12 is provided with a stepped groove 19 and a conical guide plate 20 located below the stepped groove 19; a filter plate 21 is provided in the stepped groove 19, and discharge grooves 22 are left on both sides of the guide plate 20 and the inner wall of the weighing frame 12; a vertical limit screw 23 is provided at each of the four corners of the weighing frame 12, and a compression spring 24 is sleeved on the limit screw 23; a pressure plate 25 that cooperates with the rotation of the screw is provided at the bottom of the compression spring 24, and the compression spring 24 presses the pressure plate 25 against the side wall of the weighing frame 12, and the filter plate 21 can be limited by moving the pressure plate 25.

[0040] It should be noted that there is a gap between the baffle 16 and the inner wall of the crushing tube 9, which is convenient for putting the rice to be crushed into the crushing tube 9. In actual use, the starter motor 8 drives the reciprocating screw 15 to rotate; the bottom of the reciprocating screw 15 is provided with a limit block that cooperates with the slot on the top of the stirring shaft 10, and the stirring shaft 10 is rotatably connected to the middle position of the bottom of the crushing tube 9. When the reciprocating screw 15 rotates, it can drive the stirring shaft 10 to rotate, and then crush the rice entering the crushing tube 9; the crushed rice will fall from the filter hole of the bottom plate of the crushing tube 9 to the filter plate 21 of the weighing frame 12. During the crushing process, some rice may run out from the gap between the baffle 16 and the inner wall of the crushing tube 9. Since the baffle 16 is truncated, the rice that runs out will fall on the baffle 16 and eventually slide into the crushing tube 9 again to continue to be crushed.

[0041] When the crushed rice falls on the filter plate 21, the blower starts, and the air outlet 14 of the air chamber 13 starts to blow air toward the rice on the filter plate 21. The airflow will take away the fine powder produced during the rice crushing process; at the same time, the airflow will blow the fine rice particles, causing them to fall from the holes on the filter plate 21 to the guide plate 20, and slide down from both sides of the guide plate 20, and fall onto the base 1 through the discharge trough 22, so as to avoid affecting the weighing count before drying. When no more rice falls from the crushing cylinder 9 and the indication on the weighing device 4 no longer changes, the weight of the rice at this time is recorded.

[0042] When the weight of the rice before drying no longer changes, the heating box is started, and the air outlet 14 of the air chamber 13 blows out hot air to dry the rice on the filter plate 21. After a period of hot air drying, the moisture of the rice on the filter plate 21 is dried, and its weight will change, and the reading of the weighing device 4 will also change accordingly. When the reading of the weighing device 4 gradually stabilizes and no longer changes, the weight of the rice at this time is recorded and compared with the weight of the rice before hot air drying. The moisture content of the rice can be calculated by the weight change before and after.

[0043] The rice moisture detection device of the utility model performs a rice crushing process before the rice is weighed, and starts a blower to blow away fine powder before weighing, thereby eliminating the influence of fine powder on the rice moisture determination, being beneficial to improving the accuracy of the final rice moisture determination, being very practical, and having a good market application prospect.

[0044] The foregoing description of specific exemplary embodiments of the utility model is for the purpose of illustration and illustration. These descriptions are not intended to limit the utility model to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the utility model and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the utility model and various different options and changes. The scope of the utility model is intended to be defined by the claims and their equivalents.
