Description

Technical Field

[0001] The present invention relates to the technical field of seed production and processing, in particular to a drying device for seed production and processing. Background Art

[0002] After being fully screened and packaged, crop seeds need to be stored in warehouses for a long time before being sold for planting. Therefore, the crop seeds must be fully dried and their moisture content must be controlled to avoid mold and fermentation in the warehouse. Crop seeds are generally dried slowly at a low temperature during the drying process, so the production line used for seed drying needs to be of sufficient length to achieve the slow drying method. However, such equipment is large in size during use and occupies a large factory area, which cannot meet the user's needs. There is also a stacked non-automated production drying method in the prior art, that is, multiple hollow partitions are stacked horizontally up and down inside the drying equipment to dry the seeds on the partitions. Although this method reduces the volume of the drying equipment and can meet the effect of drying a large number of seeds at one time, the seeds on the bottom partitions of the drying equipment will generate high-temperature water vapor during the drying process. The rising water vapor will cause erosion and auxiliary effects on the seeds dried on the upper partitions, which will affect the survival rate of the seeds, and the drying time of each layer of seeds will also be different.

[0003] Therefore, a drying device for seed production and processing is proposed. Summary of the Invention

The outer ring of the drum 9 is fixedly connected with several paddles 10 at equal distances, and the paddles 10 are made of hard rubber. The length of the paddles 10 is greater than the gap between the drum 9 and the conveying mesh plate 7. The front and rear ends of the drum 9 are designed as a closed structure with a hollow interior. The front and rear ends of the drum 9 are fixedly connected with a baffle 14 with a disc-shaped structure. The center positions of the front and rear ends of the drum 9 are fixedly connected with a conveying shaft 13. The conveying shaft 13 at the rear end of the drum 9 is fixed to the output end of the drive motor 5. The hollow structure design of the conveying shaft 13 at the front end of the drum 9 is connected to the interior of the drum 9, and the conveying shaft 13 at the front end of the drum 9 extends through the hole 4 to the outside of the drying box 1 and is connected to the external gas filtering equipment.

[0019] Specifically, a seed turning shovel structure is provided between adjacent paddles 10, and the seed turning shovel structure includes a toggle shaft 15 rotatably connected to the baffle 14 at both ends, and a toggle plate 16 is fixedly connected to the outside of the toggle shaft 15 away from the outer wall of the drum 9. The inner walls of the front and rear sides of the drying box 1 are provided with driving grooves of an annular structure at positions corresponding to the toggle shaft 15, and a rack 18 of an annular structure is fixedly connected inside the driving groove. Semicircular gears are meshed with positions corresponding to the toggle shaft 15 on the rack 18, and the semicircular gears are fixedly connected to the toggle shaft 15. The end of the toggle plate 16 away from the toggle shaft 15 does not contact the conveying mesh plate 7, and the rotation range of the toggle shaft 15 is between zero and one hundred and thirty degrees. A torsion spring 19 is provided between the semicircular gear and the baffle 14, and the torsion spring 19 is sleeved on the outside of the toggle shaft 15, one end of the toggle spring 19 is fixed to the toggle shaft 15, and the other end is fixed to the baffle 14.

[0020] Specifically, a nozzle 12 is embedded and connected at equal distances on the inclined surface of the inner wall of the feed hopper 3, and an air pipe 11 connected to the nozzle 12 is fixed in the feed hopper 3. One end of the air pipe 11 extends out of the feed hopper 3 and is connected to the output end of the external gas filtering equipment.

[0021] Working principle: First, this application matches the external automatic seed feeding equipment with the feeding hopper of the device, and feeds the seeds into the feeding hopper through the automatic seed feeding equipment, and then feeds them into the drying box 1 through the feeding hopper, and into the gap between the right side of the drum 9 and the drying box 1, and then the seeds fall to the right side of the drum 9 and the gap between the drying box 1 until the seeds fill the gap between the two paddles 10, and in this process, the driving motor 5 is controlled by the external intelligent controller to slowly drive the drum 9 to rotate clockwise, and the rotation of the drum 9 will drive the two paddles 10 and the seeds between the two paddles 10 to move on the conveying mesh 7. In this process, the heating plate 6 on the lower side of the conveying mesh 7 is in operation to heat the air on the upper side of the heating plate 6, and then the high-temperature air rises and contacts the passing seeds to dry the moisture on the surface of the seeds; In the process of drying seeds, the seed turning and shoveling structure will also operate. Specifically, during the clockwise rotation and displacement of the drum 9, the drum 9 drives the baffle 14 to rotate and displace, and then the semicircular gear on the baffle 14 engages with the rack 18 in the driving groove, thereby driving the semicircular gear to rotate. Due to the semicircular structure of the semicircular gear, it can only drive the semicircular gear to rotate within a specified angle range, and then reset under the action of the torsion spring 19. The semicircular gear drives the toggle shaft 15 to rotate during the rotation, and the rotation of the toggle shaft 15 further drives the toggle plate 16 to flip, and the toggle plate 16 flips to flip the seeds on both sides, thereby realizing the seed turning, so that each seed is turned. The position is in contact with the hot air below to achieve comprehensive drying of the seeds. During the seed drying process, the external gas treatment equipment is connected to the front hollow structure conveying shaft 13 to suck the air inside the drum 9, thereby avoiding the hot air inside the drying box 1 from gathering to form condensed water that drips down on the surface of the drum 9 or the surface of the seeds, thereby avoiding the impact on the seed drying. The sucked out air also contains temperature. In order to improve the utilization rate of heat, the moisture in the sucked high-temperature wet air is filtered and then conveyed to the air pipe 11. It is sprayed on the surface of the seeds falling from the feed hopper 3 through the nozzle 12 to pre-dry the fallen seeds, thereby saving resources, energy saving and environmental protection.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
