Description

Technical Field

[0001] This utility model relates to the field of corn kernel processing technology, specifically to a corn kernel drying equipment. Background Technology

[0002] Corn kernel drying equipment is specially designed to remove moisture from corn. It adopts hot air circulation and vibration technology, which is highly efficient and energy-saving, ensuring uniform drying and stable quality.

[0003] Traditional corn kernel drying equipment relies on conveyor belts to transport corn kernels into the dryer. During the conveying and drying stages, the corn kernels are mostly in a static, piled-up state. Due to the lack of a turning mechanism, the corn kernels cannot fully contact the heat source, resulting in extremely uneven heating. Some corn kernels may be overheated and damaged, while others may be underheated and fail to achieve the desired drying effect. This not only affects the final quality of the corn but also reduces drying efficiency. Therefore, a new corn kernel drying device is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that traditional corn kernel drying equipment relies on a transmission belt to transport corn kernels into the dryer. During the conveying and drying process, the corn kernels are mostly in a static pile state.

[0008] Furthermore, the transmission mechanism also includes a convex groove. The top of the linkage block has a convex groove, and a convex rod is movably installed inside the convex groove. The convex rod is fixedly connected to the mounting plate. The side wall of the linkage block has a threaded hole that communicates with the convex groove, and a bolt is threadedly connected inside the threaded hole.

[0009] Furthermore, the mesh cover assembly includes a mesh cover, with an inverted U-shaped mesh cover fixedly installed on the top of the two side plates.

[0017] like Figure 1-5 As shown, a corn kernel drying device includes two side plates 1. Two support legs 2 are fixedly installed at the bottom of each side plate 1. A stabilizing rod 3 is installed below each side plate 1, with both ends of each stabilizing rod 3 fixedly connected to the adjacent support leg 2. A mesh belt conveyor 4 for conveying corn kernels is installed between the two side plates 1. Two dryers 5 for drying corn kernels are fixedly installed at the top of the two side plates 1. An airflow jet assembly 6 for turning the corn kernels is installed below the mesh belt conveyor 4. Figure 1-3 As shown, specifically, the airflow jet assembly 6 includes a base plate 601, a base plate 601 is provided below the side of the stabilizer bar 3, an air compressor 602 is fixedly installed on the top of the base plate 601, an air pipe 603 is fixedly connected to the output end of the air compressor 602, an mounting plate 604 is provided below the mesh belt conveyor 4, an mounting hole 605 is opened on the top of the mounting plate 604, a nozzle 606 is fixedly connected to the output end of the air pipe 603, and the nozzle 606 is fixedly installed inside the mounting hole 605.

[0018] More specifically, the pulsed compressed air generated by the air compressor 602 is sent to the nozzle 606 through the air pipe 603. The nozzle 606 passes through the mounting hole 605 of the mounting plate 604 and sprays a high-speed airflow into the gap of the mesh belt conveyor 4, causing the corn kernels to tumble on the surface of the mesh belt conveyor 4.

[0019] Below the mesh belt conveyor 4 is a transmission mechanism 7 for changing the position of the airflow outlet of the airflow injection assembly 6, such as... Figure 1-3 As shown, specifically, the transmission mechanism 7 includes a block 701, with a block 701 fixedly installed on the top of each stabilizer rod 3. A lead screw 702 is movably installed between two blocks 701. A servo motor 703 for rotating the lead screw 702 is fixedly installed on the side wall of the block 701 away from the air compressor 602. A linkage block 704 is threaded onto the servo motor 703. A round rod 705 passing through the linkage block 704 is fixedly installed between the two blocks 701. The mounting plate 604 is located to the side of the linkage block 704.

[0020] The transmission mechanism 7 also includes a convex groove 706. The top of the linkage block 704 is provided with a convex groove 706. A convex rod 707 is movably installed inside the convex groove 706. The convex rod 707 is fixedly connected to the mounting plate 604. A threaded hole 708 communicating with the convex groove 706 is provided on the side wall of the linkage block 704. A bolt 709 is threadedly connected inside the threaded hole 708.

[0021] More specifically, the servo motor 703 drives the lead screw 702 to rotate according to the forward and reverse rhythm set by the PLC. The linkage block 704 reciprocates at a uniform speed along the axial direction due to the circumferential limitation of the round rod 705. The mounting plate 604 moves synchronously with the linkage block 704, so that the spray position of the nozzle 606 periodically scans in the width direction of the mesh belt conveyor 4, ensuring that the corn kernels on the mesh belt conveyor 4 can be fully turned over.

[0022] First, loosen bolt 709. The convex rod 707 can slide up and down in the convex groove 706 to adjust the blowing position of the nozzle 606. After adjustment, tighten bolt 709 to lock it in place.

[0023] A mesh cover assembly 8 is installed above the mesh belt conveyor 4 to prevent corn kernels from falling off, such as... Figure 1 , 4 As shown, specifically, the mesh cover assembly 8 includes a mesh cover 801. The tops of the two side plates 1 are jointly and fixedly installed with an inverted U-shaped mesh cover 801. The top of each side plate 1 is fixedly installed with a side rod 802. The two side rods 802 are provided with a sliding groove 803 on the side that is close to each other. A sealing plate 804 is provided above the mesh belt conveyor 4. The two ends of the sealing plate 804 are respectively movably installed inside the two sliding grooves 803. The side wall of each side rod 802 is provided with a tapping hole 805 that communicates with the corresponding sliding groove 803. Each tapping hole 805 is threaded with a bolt 806.

[0024] More specifically, the inverted U-shaped mesh cover 801 blocks particles from flying out, and after the sealing plate 804 is inserted along the slide groove 803, its lower edge maintains a suitable gap with the mesh belt surface of the mesh belt conveyor 4. The bolt 806 tightens the sealing plate 804 through the tapping hole 805 to fix the current height of the sealing plate 804.

[0025] Above the mesh belt conveyor 4 is a turning mechanism 9 for spreading corn kernels evenly. Both the mesh cover assembly 8 and the turning mechanism 9 are located between the two dryers 5. Figure 1 , 5As shown, specifically, the flipping mechanism 9 includes a second block 901. A second block 901 is fixedly installed on the top of each side plate 1. A threaded rod 902 is movably installed between two second blocks 901. A servo motor 903 for rotating the threaded rod 902 is fixedly installed on the side wall of the second block 901 away from the air compressor 602. A moving block 904 is threadedly connected to the threaded rod 902. A limiting rod 905 that passes through the moving block 904 is fixedly installed between two second blocks 901. A connecting block 906 is fixedly installed at the bottom of the moving block 904. A strip plate 907 is fixedly installed at the bottom of the connecting block 906. Several evenly distributed diverting rods 908 are fixedly installed at the bottom of the strip plate 907.

[0026] More specifically, the servo motor 903 drives the threaded rod 902 to periodically rotate forward and backward. Under the guidance of the limit rod 905, the moving block 904 drives the strip plate 907 to reciprocate at a uniform speed above the mesh belt of the mesh belt conveyor 4. The diverting rod 908 promptly flattens out any local piles that might have reappeared.

[0027] In summary: First, the corn kernels are spread evenly on the mesh belt conveyor 4. After the equipment is started, the mesh belt conveyor 4 continuously feeds the corn kernels into the two dryers 5. After the corn kernels come out of the first dryer 5, the output end of the air jet component 6 moves back and forth under the drive of the transmission mechanism 7, spraying air upward from below the mesh belt conveyor 4. The sprayed air jet tumbles and throws the corn kernels up. The mesh cover component 8 limits the throwing height to prevent splashing. After the corn kernels fall back and come out of the mesh cover component 8, the tumbling mechanism 9 continues to spread the corn kernels evenly, so that the corn kernels are evenly tumbled and then enter the second dryer 5 for further drying. This allows the corn kernels to be evenly heated and dehydrated simultaneously. Finally, the finished product is discharged from the end of the mesh belt conveyor 4.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
