Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing equipment technology, and in particular to a corn thresher for food processing. Background Technology

[0002] Corn is an annual herbaceous plant of the Poaceae family, also known as maize, corncob, and pearl rice. It originated in Central and South America and is an important food crop worldwide, widely distributed in the United States, China, Brazil, and other countries. Compared with traditional food crops such as rice and wheat, corn has strong drought resistance, cold resistance, tolerance to poor soil, and excellent environmental adaptability. Corn has high nutritional value and is an excellent food crop.

[0003] Before corn processing, it is often necessary to separate the corn kernels from the corn cobs for threshing. Most existing corn threshers have threshing mechanisms with a fixed diameter. However, even corn of the same variety from the same field can vary in diameter. Corn with a smaller diameter may not make sufficient contact with the threshing mechanism during threshing, resulting in poor threshing effect. Corn with a larger diameter may cause the corn cob to come into contact with the threshing mechanism, resulting in cob fragments being mixed into the corn kernels.

[0004] Therefore, to address the above problems, a corn thresher for food processing can be designed so that the device can adapt to corn of different diameters, thereby ensuring the threshing effect of corn of different diameters. Utility Model Content

[0005] To overcome the need to separate corn kernels from corn cobs for threshing before corn processing, most existing corn threshers have threshing mechanisms with a fixed diameter. However, even corn of the same variety from the same field can vary in diameter. Corn with a smaller diameter may not make sufficient contact with the threshing mechanism during threshing, resulting in poor threshing results. Corn with a larger diameter may cause the corn cob to come into contact with the threshing mechanism, resulting in the corn kernels being mixed with cob fragments.

A sliding connection is used. A threshing motor 8 is installed above the threshing box 1, and a drive assembly is installed at the output end of the threshing motor 8. The conveyor motor 9 drives the conveyor 2 and the conveyor roller 3 to convey the corn. The conveyor motor 9 drives the mounting ring 4 to rotate through the drive assembly, thereby causing the threshing block 5 to rotate and thresh the moving corn. During the movement of the corn, the movable head 7 will automatically adjust the extension length according to the diameter of the corn, so that the conveyor roller 3 can clamp the thinner corn more forcefully, ensuring the conveying force of the corn. When the movable seat 6 contacts the corn, it will also automatically adjust its position according to the diameter of the corn and drive the threshing block 5 to move together, so that the threshing block 5 is always at the corn kernel part for threshing.

[0024] Please see Figures 1-2 In this embodiment, a guide plate 201 is provided above the conveyor 2, and a grain outlet 101 is provided at the bottom of the threshing box 1. A first transmission belt 301 is provided between the conveyor 2 and the conveying roller 3 on one side of the bottom, and a second transmission belt 302 is provided between the conveying rollers 3 on both sides of the top. A transmission gear 303 is provided at the same end of the conveying roller 3 on the same side, and the transmission gears 303 mesh with each other. The guide plate 201 screens the posture of the corn and conveys the corn axially. The grain outlet 101 serves as the channel for the corn kernels to be discharged. The conveyor motor 9 drives the conveyor 2 to convey the corn. At the same time, the first transmission belt 301 transmits power to the conveying roller 3, and the transmission gear 303 and the second transmission belt 302 drive all the conveying rollers 3 to rotate and convey the corn.

[0025] Please see Figure 3In this embodiment, the drive assembly includes a drive gear 801 and a driven gear ring 802. The output end of the threshing motor 8 is provided with the drive gear 801, and the outer side of the mounting ring 4 is provided with the driven gear ring 802. The driven gear ring 802 meshes with the drive gear 801. Support seats 803 are provided on both sides of the drive gear 801, and the support seats 803 are rotatably connected to the drive gear 801. The support seats 803 support and install the drive gear 801. The threshing motor 8 drives the drive gear 801 to rotate, and drives the driven gear ring 802 and the mounting ring 4 to rotate, thereby causing the threshing block 5 to rotate around the corn for threshing.

[0026] Please see Figure 4 In this embodiment, a ball bearing 606 is provided inside the movable seat 6, and the ball bearing 606 is in rolling connection with the movable seat 6. An mounting plate 601 is provided on the side of the mounting ring 4 near the conveyor 2. A first guide rod 602 is provided on the end of the movable seat 6 away from the ball bearing 606, and the first guide rod 602 is slidably connected to the mounting plate 601. A first spring 603 is provided on the outer side of the first guide rod 602. A second guide rod 605 is provided on one side of the threshing block 5, and the second guide rod 605 is slidably connected to the mounting ring 4. The second guide rod 605 is located away from the threshing block 5. A connecting block 604 is provided at one end, and the connecting block 604 is fixedly connected to the second guide rod 605 and the first guide rod 602. The ball bearing 606 contacts the corn, and at the same time, the axial movement of the corn causes the ball bearing 606 to roll inside the movable seat 6 and push the movable seat 6 to compress the first spring 603, causing the first guide rod 602 to move outward of the mounting ring 4. The connecting block 604 and the second guide rod 605 drive the threshing block 5 to move outward of the mounting ring 4. Corn of different diameters will cause the threshing block 5 to move different distances, so that the threshing block 5 is always located in the corn kernel layer.

[0027] Please see Figure 5 In this embodiment, the conveying roller 3 has multiple sets of movable holes 704, and the movable head 7 is located inside the movable hole 704. One end of the movable head 7 is provided with a second spring 701, the inside of the movable hole 704 is provided with a second limiting block 703, and one end of the movable head 7 is provided with a first limiting block 702. When the conveying roller 3 contacts the corn, the movable head 7 contacts the corn and slides and compresses the second spring 701 within the movable hole 704. Different diameter corn will cause the movable head 7 to move different distances, so that the conveying roller 3 can convey corn of different diameters. The second limiting block 703 and the first limiting block 702 limit the movement stroke of the movable head 7.

[0028] During threshing, the conveyor motor 9 drives the conveyor 2 to transport the corn. Simultaneously, the first transmission belt 301 transmits power to the conveyor rollers 3, which in turn rotate via the transmission gear 303 and the second transmission belt 302 to transport the corn. When the conveyor rollers 3 contact the corn, the movable head 7 contacts the corn and slides within the movable hole 704, compressing the second spring 701. Different diameter corn will cause the movable head 7 to move different distances, allowing the conveyor rollers 3 to transport corn of different diameters. The threshing motor 8 drives the drive gear 80... 1. Rotation causes the driven toothed ring 802 and mounting ring 4 to rotate, thereby causing the threshing block 5 to rotate around the corn for threshing. The ball bearing 606 contacts the corn, and at the same time, the axial movement of the corn causes the ball bearing 606 to roll inside the movable seat 6 and push the movable seat 6 to compress the first spring 603, causing the first guide rod 602 to move outward of the mounting ring 4. The connecting block 604 and the second guide rod 605 drive the threshing block 5 to move outward of the mounting ring 4. Corn of different diameters will cause the threshing block 5 to move different distances, so that the threshing block 5 is always located in the corn kernel layer.
