Description

Technical Field

[0001] The utility model relates to the technical field of seed moisture detection equipment, in particular to a seed moisture detection device. Background Art

[0002] Seed is a reproductive body unique to gymnosperms and angiosperms. It is formed by ovules through pollination and fertilization. Seeds generally consist of three parts: seed coat, embryo and endosperm. The mature seeds of some plants only have two parts: seed coat and embryo.

[0003] The most common way to test seeds is to record the weight of the seeds, dry the water they contain, and then weigh them again. The difference between the two weights is the moisture content of the seeds.

[0004] The traditional drying method only uses heating to increase the temperature inside the container and then dry the seeds. Some detection devices will also crush the seeds, that is, use blades to crush the seeds. During the direct drying process, due to the limited space inside the container, the seeds cannot directly contact the inner wall of the container, so that they can only be heated by transferring heat through the air. The transfer process is relatively slow, resulting in a slow drying speed. Although it can be dried faster after crushing, seed debris is easy to adhere to the blades and some dead corners, which can easily lead to inaccurate weighing results. Therefore, a seed moisture detection device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] Based on the above description, the utility model provides a seed moisture detection device to solve the problem that the direct drying speed is slow and the seed is easily broken by a blade, which may lead to inaccurate weighing results.

It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0031] See also Figure 1 and Figure 4 , a seed moisture detection device, comprising:

[0032] The device housing comprises a mounting base 1 and a stand 2, wherein the mounting base 1 comprises a hollow base 11, and a protrusion 12 and a positioning block 13 are respectively arranged on the bottom wall and the side wall inside the hollow base 11;

[0033] A stand 2, which is arranged on the outer surface of the mounting seat 1 and includes an internally threaded sleeve 23, the stand 2 includes a main frame body 21, the main frame body 21 is arranged on the outer surface of the hollow base 11, a horizontal plate 22 is arranged inside the main frame body 21, and an internally threaded sleeve 23 extending to the bottom of the horizontal plate 22 is arranged on the top of the horizontal plate 22;

[0034] Based on the above, the protrusion 12 and the positioning block 13 cooperate with each other to limit the drying plate 3, thereby preventing the drying plate 3 from rotating. The protrusion 12 also increases the heat exchange area, so that the heat generated by the heating block 4 can be transferred to the drying plate 3 through the mounting base 1 more quickly. The setting of the internal threaded sleeve 23 enables the pressing block 5 to move vertically under the action of the threaded transmission.

[0035] like Figure 3 , Figure 5 and Figure 6 As shown, a drying tray 3 is arranged inside the mounting base 1, and the drying tray 3 includes a main tray body 31. The upper and lower surfaces of the main tray body 31 are respectively provided with an arc-shaped receiving groove 32 and a groove 34, the protrusion 12 extends to the inside of the groove 34, and the outer surface of the main tray body 31 is provided with a side positioning groove 33, and the positioning block 13 extends to the inside of the side positioning groove 33;

[0036] A heating block 4 is disposed at the bottom end of the mounting base 1 and extends to the inside of the mounting base 1. The heating block 4 includes a base body and an electric heating coil. The electric heating coil is disposed inside the base body.

[0037] Based on the above, the side positioning groove 33 on the side of the drying plate 3 cooperates with the positioning block 13 to position the drying plate 3, and the groove 34 cooperates with the protrusion 12, which on the one hand plays a positioning role, and on the other hand plays an effect of enhancing heat transfer, and the arc-shaped storage groove 32 plays a role in storing seeds, and the electric heating coil inside the heating block 4 plays a role in generating heat after being energized.

[0038] like Figure 1-Figure 3 , Figure 7 and Figure 8 As shown, the pressing block 5 is arranged inside the stand 2 and extends to the inside of the drying tray 3, and includes a metal block 51, a threaded column 52 and a guide block 53. The pressing block 5 includes the metal block 51, the lower surface of the metal block 51 is an arc surface, and the top of the metal block 51 is sequentially provided with a threaded column 52 and a guide block 53 from bottom to top, and the threaded column 52 is threadedly connected with the internal threaded sleeve 23;

[0039] A servo motor 6 is disposed at the top of the stand 2;

[0040] A transmission block 7, which is arranged outside the guide block 53 and connected to the output shaft of the servo motor 6, the transmission block 7 includes a block body 71, and one end of the block body 71 close to the mounting seat 1 is provided with a limiting ring 72 and a guide blind hole 73, the guide blind hole 73 is adapted to the guide block 53, and a support spring 8 is provided between the transmission block 7 and the cross plate 22;

[0041] Based on the above, the servo motor 6 drives the threaded column 52 to rotate by driving the transmission block 7 to rotate, so that the threaded column 52 moves vertically under the action of the internal threaded sleeve 23. During the vertical movement, the guide block 53 moves along the direction of the guide blind hole 73.

[0042] In actual use of this embodiment, the seeds are placed in the arc-shaped receiving groove 32, and the drying plate 3 is placed inside the mounting base 1;

[0043] Heat is generated by energizing the electric heating coil inside the heating block 4, and the heat is transferred to the drying plate 3 through the mounting base 1, so that the seeds inside the drying plate 3 are dried. During this process, the servo motor 6 is energized to drive the transmission block 7 to rotate, and the transmission block 7 drives the threaded column 52 to rotate. At this time, the threaded column 52 moves downward under the action of the internal threaded sleeve 23, and drives the metal block 51 to move downward together;

[0044] During the movement, the seeds are squeezed so that the seeds are spread out under the action of pressure. The spread seeds are in direct contact with the surface of the drying plate 3. Compared with the indirect heat transfer through air, the direct contact heat transfer efficiency is higher. When the metal block 51 continues to press down, on the one hand, the metal block 51 is heated by the heat and heats the other surface of the seeds. On the other hand, the seeds are crushed after being squeezed. The crushed seeds have a larger heating area and are easier to dry.

[0045] After drying, since the lower surface of the metal block 51 is an arc-shaped surface and the inner wall of the arc-shaped receiving groove 32 is also smooth, there is no dead corner, so when the seed debris is cleaned out, it can avoid the situation of residue, thereby ensuring that the weighing data of the seed debris after drying is sufficiently accurate;

[0046] The detection device spreads the seeds and then heats them by arranging a pressing block 5 and a drying plate 3, and crushes the seeds during the heating process, which not only speeds up the drying speed, but also the structure of the drying plate 3 and the pressing block 5 ensures that debris will not adhere to dead corners and be difficult to be removed.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
