[0002] Wheat seed moisture detection is an important link to ensure seed quality and agricultural production safety.

DETAILED DESCRIPTION

[0035] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described.

[0036] The present invention provides a wheat seed moisture detection device and an evaporation detection method thereof. The technical solution of the present invention is:

The outer peripheral wall of the inner cylinder 17 is provided with a plurality of V-grooves 170. The inner peripheral wall of the inner cylinder 17 is fixed with a plurality of guide plates 16. The number and position of the guide plates 16 and the V-grooves 170 correspond one to one. The bottom of the V-grooves 170 is provided with a plurality of through holes 1700 penetrating the inner cylinder 17. The cavity formed between each guide plate 16 and the inner cylinder 17 and the plurality of through holes on the corresponding V-grooves 170 are connected to the inner cylinder 17. The flow hole 1700 is connected, and a flow ring strip 38 is fixedly connected between the guide plate 16 at the bottom and the inner cylinder 17. The bottom of the flow ring strip 38 is rotatably connected to an actuated ring plate 41, and the actuated ring plate 41 is rotated between the bottom ring strip 39 and the inner cylinder 17. The inner wall of the bottom ring strip 39 is movably connected to the bottom material plate 26. When the bottom material plate 26 and the bottom ring strip 39 are movably misaligned to produce a gap, the material contained in the bottom material plate 26 can leak out through the misaligned gap.

[0038] Regarding the transmission between the supporting groove wheel 36, the vibration motor 23 and the inner cylinder 17, it should be noted that: Figure 2 and Figure 3 As shown, the groove shape of the supporting groove wheel 36 is consistent with the groove pattern of the outer wall of the inner cylinder 17, and its purpose is to drive the inner cylinder 17 to move up and down when it is moved. When the vibration motor 23 drives the vibration plate 25 to vibrate, since the spring can be used to transmit the same frequency vibration, the vibration plate 25 drives each supporting groove wheel 36, thereby driving the inner cylinder 17 to vibrate, thereby driving the wheat seeds at the bottom to vibrate.

[0039] Furthermore, the weighing plate 8 is provided with a display and a weighing indicator line 7. The weighing plate 8 itself can be used as a conventional electronic scale to weigh within the area indicated by the weighing indicator line 7. Basic adjustment buttons are also provided next to the display for conventional peeling and unit conversion. The support column 19 and its connecting parts above the weighing plate 8 are all arranged on the weighing plate 8. The weighing plate 8 can measure the weight of the support column 19 and its connecting parts, so that when the wheat seeds are placed in the inner cylinder 17, the weighing plate 8 can also be used to measure the quality of the seeds contained in the device.

[0040] As an optional option to the above scheme, the inner circumferential wall of the rotating cylinder plate 33 is provided with a plurality of movable grooves 34, and the outer circumferential wall of the bottom ring strip 39 is provided with a plurality of bayonet holes 391, and the movable grooves 34 correspond to the bayonet holes 391 one by one, and a movable block 40 is slidably inserted in the interior of each movable groove 34, and an extension rod 401 is integrally formed on one side of the movable block 40, and an inner groove 43 is also provided in the interior of the movable groove 34, and the extension rod 401 is movably inserted in the inner groove 43, and a spring 2 42 is provided between the extension rod 401 and the inner wall of the inner groove 43, and a plurality of inner linkage grooves 390 are provided in the inner circumferential wall of the bottom ring strip 39, and a connecting cylinder plate 18 is fixedly provided at the bottom of the bottom ring strip 39; a frame plate 2 is fixed on the top of the outer cylinder 5, and both sides of the frame plate 2 A card slot 4 is provided, a central column 13 is movably inserted inside the frame plate 2, and the bottom of the central column 13 is fixed to the bottom plate 26, a support ring 15 is movably sleeved on the outside of the central column 13, a press plate 1 is fixed on the top of the support ring 15, a spring 14 is provided between the support ring 15 and the frame plate 2, and the spring 14 is sleeved on the outside of the central column 13, a removable cover plate 11 is inserted on one side of the frame plate 2, blocks 10 are fixed on both sides of the inner wall of the cover plate 11, the two blocks 10 can be inserted into the card slot 4 so that the cover plate 11 can seal the top of the outer cylinder 5, a stirring plate 27 is fixed on the outer wall of the central column 13, the stirring plate 27 is spiral, and in the absence of external force, the seeds fall on the stirring plate 27 and roll downward.

[0041] When each evaporation operation is completed, stop each motor, pull out the cover plate 11, and press the pressing plate 1 repeatedly to move the bottom plate 26 downward and dislocate it from the bottom ring strip 39, so that the wheat seeds flow out of the gap into the interior of the container 9, making it easier for the seeds to be taken out.

[0042] As an optional option to the above scheme, a plurality of ring holes 410 are provided on the top of the driven ring plate 41, a plurality of flow guide holes 380 are provided on the flow ring strip 38, and the ring holes 410 correspond to the flow guide holes 380 one by one, and the portion between every two adjacent ring holes 410 can close a flow guide hole 380, and the driven ring plate 41 is integrally formed with an outer ring plate 411, and the outer ring plate 411 is provided with a plurality of through holes 4110.

[0043] Specifically, when the rotating cylinder plate 33 moves upward, due to the squeezing effect of the spring 2 42, the movable block 40 moves out of the movable groove 34 and enters the bayonet 391. If the movable block 40 does not initially enter the bayonet 391, when the rotating motor 47 is started, the movable block 40 will also be driven to rotate into the bayonet 391, thereby driving the bottom ring bar 39 to rotate. The inner linkage groove 390 provided in the bottom ring bar 39 is inserted into the protrusion of the bottom material plate 26 inside it, which can drive the rotation of the bottom material plate 26 and the center column 13, so that the stirring plate 27 rotates to stir the seeds at a low speed, and combines with the airflow to take away the water vapor.

[0044] Among them, the actuating principle of the actuated ring plate 41 is: when the telescopic motor 21 drives the rotating cylinder plate 33 to rise, the top of the rotating cylinder plate 33 squeezes the adjusting ring plate 49, so that the spring three 44 is compressed, and the inclined block 46 moves to the top of the inclined hole 45, prompting the actuated ring plate 41 to rotate, so as to realize the function of opening and closing the flow guide hole 380.

[0045] Based on the principle of closing or opening the flow guide holes 380 by rotating the above-mentioned driven ring plate 41, the present invention also provides an embodiment for isolating seeds to prevent possible outflow during the operation, specifically: the driven ring plate 41 is replaced by a partition mesh plate that is smaller than the seed particle size, the partition mesh plate is arranged at the bottom of the flow ring bar 38, and the partition mesh plate is also arranged between each guide plate 16 and the inner circumferential wall of the inner tube 17. When the gas is always flowing and the vibration operation is performed on the seeds to increase the distance between each other, it is ensured that the seeds will not enter any gas guide space.

[0046] The outer wall of the extended ring plate 411 is also provided with a plurality of inclined holes 45, the outer wall of the bottom ring strip 39 is movably sleeved with an adjusting ring plate 49, the outer wall of the adjusting ring plate 49 is provided with a plurality of inclined blocks 46, each inclined block 46 is inserted into the corresponding inclined hole 45, a plurality of groups of springs 44 are provided between the adjusting ring plate 49 and the vibration plate 25, and each group of springs 44 passes through the corresponding through hole 4110, so that the adjusting ring plate 49 is initially located at the bottom, and the passive ring plate 41 will close the flow guide hole 380 to prevent the seeds from flowing out to the top of the flow ring strip 38 during vibration.

[0047] Furthermore, a telescopic motor 21 is fixed on the support plate 6, and a telescopic rod 20 is fixed to the output shaft of the telescopic motor 21. An extension plate 31 is integrally formed on the outer peripheral wall of the lifting cylinder plate 30, and the telescopic rod 20 is fixed to the extension plate 31. A gear ring strip 51 is fixedly sleeved on the outer wall of the rotating cylinder plate 33, and a rotating motor 47 is fixed to the top of the support plate 6. A transmission tooth 24 is fixed to the output shaft of the rotating motor 47 through a coupling, and the transmission tooth 24 is meshed with the gear ring strip 51. When the telescopic motor 21 drives the rotating cylinder plate 33 to rise, the gear ring strip 51 is also moved and raised by it. The tooth surface height of the gear ring strip 51 in the present invention is much higher than that of the transmission tooth 24 to ensure that the transmission tooth 24 and the gear ring strip 51 can still be in a meshing state, so that the rotating cylinder plate 33 can be driven to rotate when the rotating motor 47 is transmitted.

[0048] As an optional scheme to the above, all the supporting groove wheels 36 are provided with annular plates 56 at the top and bottom, and a plurality of springs 50 are provided between the annular plates 56 at the bottom and the vibration plate 25, and each spring 50 is sleeved on the outside of the corresponding rotating shaft 35, and the outside of the outer tube 5 is plugged with an air inlet pipe 3, the air inlet pipe 3 is connected to the inside of the outer tube 5, and the top of the cover plate 11 is plugged with an air outlet pipe 12.

The gas passes through the flow ring strip 38 and enters the interior of the inner tube 17, contacts the surface of the wheat seeds, evaporates them, and takes away moisture. The mixed gas flows up through the air outlet pipe 12 to achieve the moisture detection effect of the wheat seeds.
