Description

Technical Field

[0001] The utility model relates to the technical field of moisture detection, and more specifically to a seed moisture detection device. Background Art

[0002] Seed moisture determination refers to determining the seed moisture content of a test sample, providing a basis for safe seed storage and transportation. Seed moisture determination must completely remove free water and bound water from the seed moisture, while minimizing the loss of oxidation, decomposition, or other volatile substances as much as possible. Seed moisture, also known as seed water content, refers to the percentage of the weight of water contained in the seed sample to the weight of the seed sample. Existing seed detection devices all select an appropriate amount of seeds and place them into the detection device, close the top cover, weigh them first, start drying them after weighing, weigh them again after drying, and calculate the moisture content of the seeds based on the difference in the weighing results on the front and back sides. However, their drying devices all start drying from the bottom of the seeds. If the drying time is too short, the moisture on the top of the seeds is not safely dried. If the drying time is too long, the bottom part of the seeds is burnt into ash, which in turn causes damage to the seeds, reduces the accuracy of seed moisture detection, and is inconvenient for staff to use. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a seed moisture detection device to solve the problems existing in the above-mentioned background technology.

[0004] The utility model provides the following technical solution: a seed moisture detection device, comprising a control device, a display screen is provided on the top of the control device, a weighing detection device is provided on one side of the control device, a cooling fan is provided at the bottom of the weighing detection device, an electric heating column is provided inside the weighing detection device, a weighing plate is provided inside the control device, a connecting plate located above the weighing plate is provided inside the control device, a drying column is provided at the bottom of the connecting plate, spring columns are provided around the bottom of the weighing plate, a pressure sensor is provided on the top of the spring column, seeds are evenly placed inside the drying column through a plurality of drying columns, and the outer side of the drying column is heated by the electric heating column, so that the seeds inside are surrounded by heating and drying, thereby improving the drying efficiency of the seeds in the drying column, and after the drying measurement is completed, the cooling fan can be started to discharge the hot air in the weighing detection device, thereby reducing the temperature inside the weighing detection device, preventing the temperature inside the weighing detection device from being too high and causing interference with the next group of measurement results, thereby increasing the accuracy of seed moisture detection;

[0005] Furthermore, a guide plate located inside the weighing detection device is provided on the top of the weighing plate, which guides the weighing plate to maintain the balance of the weighing plate, making it convenient for the cooling fan on the top of the spring column to measure the weight of the connecting plate and the seeds inside it.

[0006] Furthermore, handles are provided on both sides of the top of the connecting plate, which make it easier for workers to take out and install the connecting plate, thereby increasing the comfort of use for the workers.

[0007] Furthermore, a top cover is provided on the top of the weighing detection device, a limit plate is provided on the bottom of the top cover, and an observation window is provided on the top of the top cover, through which the drying condition in the weighing detection device can be observed, making it convenient for staff to stop detection at any time.

[0008] Furthermore, there are eight groups of electric heating columns, and the electric heating columns are staggered on the outside of the drying column. The diameter of the drying column is 1 cm. The seeds in the drying column are heated by the eight groups of electric heating columns, so that the seeds inside the drying column are dried more completely and thoroughly.

[0009] Compared with the prior art, the beneficial effect of the present invention is that the seeds are evenly placed inside the drying columns through multiple drying columns, and the electric heating columns are used to heat the outside of the drying columns, so that the seeds inside are surrounded by heating and drying, which improves the drying efficiency of the seeds in the drying columns. After the drying measurement is completed, the cooling fan can be started to discharge the hot air in the weighing detection device, thereby reducing the temperature in the weighing detection device and preventing the temperature in the weighing detection device from being too high, which will interfere with the measurement results of the next group, thereby increasing the accuracy of seed moisture detection.

[0019] The working principle of the present invention is as follows: the seeds to be tested by the staff are placed evenly in the drying column 11, and then the connecting plate 10 is installed in the interior of the weighing detection device 3 through the handle 12. At this time, the weight of the seeds in all the drying columns 11 is measured according to the pressure sensor 7 on the top of the spring column 5. Then the top cover 13 is closed, and the electric heating column 4 is controlled by the control device 1 to make the eight groups of electric heating columns 4 heat the outside of the drying column 11, thereby surrounding the seeds inside the drying column 11 for heating and drying, thereby increasing the drying efficiency of the seeds in the drying column 11. At this time, the difference is calculated again according to the readings on the pressure sensor 7 to calculate the moisture content of the seeds; after the drying measurement is completed, the cooling fan 6 can be started to discharge the hot air in the weighing detection device 3, thereby reducing the temperature in the weighing detection device 3 and preventing the temperature in the weighing detection device 3 from being too high, which will interfere with the measurement results of the next group, thereby increasing the accuracy of seed moisture detection; at the same time, the handle 12 is convenient for the staff to remove and install the connecting plate 10 at any time, and the observation window 15 can observe the drying situation in the weighing detection device 3, making it convenient for the staff to stop the detection at any time, thereby increasing the use comfort of the staff.
