Description

Technical Field

[0001] This invention relates to the field of corn threshing technology, and more specifically to a low-damage corn threshing device. Background Technology

[0002] A corn threshing device is a mechanical device for threshing corn ears. During threshing, the corn ears enter the drum through the feeding hopper. Under the impact of the high-speed rotating drum and the interaction between the corn ears, the drum, and the concave plate, the corn kernels are knocked off the corn cob, thus achieving threshing.

[0003] In addition, some corn threshing devices can also clean the threshed kernels. Most of the threshed kernels and small impurities pass through the concave plate holes and are cleaned by airflow from the fan. Light impurities are blown out from the discharge port, kernels slide out of the machine by the kernel slide plate, and the cob moves backward along the drum axis and is discharged out of the machine through the surface of the vibrating screen from the outlet at the end of the cob. Some kernels trapped in the cob fall through the screen holes and enter the kernel slide plate to slide out of the machine.

[0004] In existing corn threshing devices, the corn threshing elements, such as the spikes and the grooves, are usually made of hard materials. If the gaps between the threshing elements are too small, the kernels will be subjected to excessive compression and impact, causing a large number of kernels to be broken. The breakage rate of dry corn with low moisture content can even reach more than 10%. The broken kernels are difficult to store, are prone to mold, and need to be screened out during processing, which increases costs. Summary of the Invention

[0005] This invention proposes a low-breakage corn threshing device, which solves the problems in related technologies where corn threshing elements such as nails and grooved rods are usually made of hard materials, and the gaps between the threshing elements are too small, which leads to excessive compression and impact on the kernels, causing a large number of kernels to be broken. The broken kernels are difficult to store, are prone to mold, and need to be additionally screened out during processing, which increases costs.

[0084] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0085] like Figures 1-15As shown, this embodiment proposes a low-breakage corn threshing device, including a support platform 1, a feeding mechanism, a threshing mechanism, a flexible fixing mechanism, a separating mechanism, and a coordinating mechanism. The feeding mechanism is located above the support platform 1, the threshing mechanism is installed on the support platform 1 and below the feeding mechanism, the flexible fixing mechanism is installed between the threshing mechanism and the feeding mechanism, the separating mechanism is installed at the bottom of the support platform 1, and the coordinating mechanism is installed on the support platform 1. When threshing corn, the corn is first fed into the feeding mechanism manually or with the help of feeding equipment. The corn enters the threshing mechanism, at which time the flexible fixing mechanism is activated first to fix both ends of the corn. The threshing mechanism is activated to thresh the corn, and the threshed kernels fall into the separating mechanism. The separating mechanism separates the kernels from light impurities and stores them separately in different containers through the coordinating mechanism.

[0086] The feeding mechanism includes a support frame 2, a storage pipe 3, a feeding pipe 4, a baffle plate 5, and a motor 6. The support frame 2 is fixedly connected to the support platform 1. There are two storage pipes 3. The feeding pipe 4 passes through the support frame 2 and is connected to the bottom of the support frame 2. The bottom ends of the two storage pipes 3 are connected to the top ends of the feeding pipe 4. There are two baffle plates 5, which are rotatably connected to the inner wall of the feeding pipe 4. There are two motors 6, which are fixedly connected to the outer wall of the feeding pipe 4. The output ends of the two motors 6 are fixedly connected to the top ends of the two baffle plates 5 respectively. When corn enters the storage pipe 3, the baffle plate 5 closes, the motor 6 starts, and drives the baffle plate 5 to open slowly, so that a single ear of corn falls into the threshing mechanism.

[0087] Secondly, the threshing mechanism includes a trough, threshing rollers 7, motor 8, and baffles 9. The trough is located in the center of the support platform 1. There are two threshing rollers 7, both of which are rotatably connected to the side wall of the trough. There are two motors 8, both of which are fixedly connected to the side wall of the support platform 1. The output ends of the two motors 8 are respectively fixedly connected to the two threshing rollers 7. There are two baffles 9, both of which are fixedly connected to the support platform 1. When the motor 8 is started, it drives the two threshing rollers 7 to rotate. The steel spikes on the threshing rollers 7 can quickly thresh the corn. The baffles 9 can prevent the kernels from popping out.

[0088] Furthermore, the flexible fixing mechanism includes a movable plate 10, a fixing ring 11, a mounting frame 12, an electric cylinder 13, a transmission assembly, and a fixing rod assembly. Two movable plates 10 are provided, slidably connected to both sides of the top of the support frame 2. Two fixing rings 11 are provided, rotatably connected to the side walls of the two movable plates 10. Two mounting frames 12 are provided, fixedly connected to the side walls of the two movable plates 10 away from the fixing rings 11. Two electric cylinders 13 are provided, fixedly connected within the two mounting frames 12. The transmission assembly is mounted on the support frame 2 and used to drive the two movable plates 10. Two fixing rod assemblies are provided, fixedly connected to the output ends of the two electric cylinders 13. First, the transmission assembly starts, cooperating with the position sensor to sense the center position of the corn. Then, the movable plate 10 is adjusted until the fixing rod assembly is aligned with the center of the corn. The electric cylinder 13 starts, driving the fixing rod assembly to insert into the corn cob. This mechanism is highly adaptable to corn of various sizes.

[0089] The transmission assembly includes a second support frame 14, threaded rods 15, and a third motor 16. There are two second support frames 14, which are fixedly connected to the top of the first support frame 2 on both sides. There are two threaded rods 15, which are rotatably connected to the two second support frames 14. The two moving plates 10 are threadedly engaged with the two threaded rods 15. There are two third motors 16, which are fixedly connected to the top of the two second support frames 14. The output ends of the two third motors 16 are fixedly connected to the two threaded rods 15. When the third motor 16 is started, it drives the threaded rods 15 to rotate, thereby driving the moving plates 10 threadedly connected to them to move in the vertical direction.

[0090] Secondly, the fixed rod assembly includes a rod body 17, a rotating rod one 18, a rotating head 19, a rotating rod two 20, a rod head 21, a piercing head 22, a pressing and resetting component, and a limiting component. The rod body 17 is slidably connected to one of the moving plates 10. One end of the rotating rod one 18 is fixedly connected to one end of the rod body 17. The rotating head 19 is fixedly connected to the other end of the rotating rod one 18. One end of the rotating rod two 20 is rotatably connected to the rotating head 19. The rod head 21 is fixedly connected to the other end of the rotating rod two 20. The piercing head 22 is fixedly connected to the rod head 21. The pressing and resetting component is installed between the rod body 17 and the rod head 21. The limiting component is installed on the support frame one 2. The rod body 17 and the rod head 21 can be bent into a certain angle under the action of the rotating rod one 18, the rotating rod two 20, and the rotating head 19. When the force between the corn and the threshing roller 7 is too large, the rotation of the rod body 17 and the rod head 21 can reduce the force borne by the corn.

[0091] Furthermore, the pressing and resetting component includes a damping anti-bending spring 23 and a damping anti-bending spring 24. The damping anti-bending spring 23 is sleeved on the rotating rod 18 and the rotating rod 20. The two ends of the damping anti-bending spring 23 are fixedly connected to the rod body 17 and the rod head 21, respectively. Multiple damping anti-bending springs 24 are provided, and multiple damping anti-bending springs 24 are fixedly connected between the rod body 17 and the rod head 21. When the fixed rod assembly bends, the damping anti-bending spring 23 and the damping anti-bending spring 24 can provide a certain flexible force to the corn, so that a certain pressure is maintained between the corn and the threshing roller 7 to prevent the fixed rod assembly from bending and causing the kernels to fail to fall off. At the same time, after the corn is threshed, the electric cylinder 13 starts to pull out the corn cob, and at the same time, the transmission component starts to move the moving plate 10 near the corn cob discharge port 35 upward to push out the corn cob, thus completing the separation of the corn cob from the kernels.

[0092] The limiting components include mounting plate 25, mounting frame 26, electric cylinder 27, support arm 28, and limiting plate 29. Mounting plate 25 is fixedly connected to one side of support platform 1, mounting frame 26 is fixedly connected to mounting plate 25, electric cylinder 27 is fixedly connected to mounting frame 26, support arm 28 is slidably connected to mounting plate 25, the output end of electric cylinder 27 is fixedly connected to support arm 28, and limiting plate 29 is fixedly connected to the bottom end of support arm 28. After the corn falls into the threshing mechanism, electric cylinder 27 starts, driving support arm 28 and limiting plate 29 to move above the corn, preventing the fixing rod assembly from bending excessively, which would prevent the corn from receiving the force of threshing roller 7 and thus prevent threshing roller 7 from threshing.

[0093] Secondly, the separation mechanism includes a support plate 30, an inclined filter plate 31, support rods 32, and electric push rods 33. The support plate 30 is fixedly connected to the ground and is located below the support platform 1. The inclined filter plate 31 is slidably connected to the support plate 30. There are two support rods 32, which are fixedly connected to the two sides of the bottom of the support platform 1. There are two electric push rods 33, which are fixedly connected to the two support rods 32. The output ends of the two electric push rods 33 are fixedly connected to the two side walls of the inclined filter plate 31. The output direction of the two electric push rods 33 is the same as the sliding direction of the inclined filter plate 31 and the support plate 30. When the electric push rods 33 are activated, they push the inclined filter plate 31 to shake, allowing small and light impurities to fall into the cooperating mechanism. At the same time, the inclined filter plate 31 can make the grains move downwards and fall into the cooperating mechanism during the shaking process.

[0094] Finally, the supporting mechanism includes a waste box 34, a corn cob outlet 35, a first collection box 36, and a second collection box 37. There are two waste boxes 34, both of which are located below the inclined strainer 31. The corn cob outlet 35 is fixedly connected to one side of the support platform 1. The first collection box 36 is fixedly connected to the side wall of the support platform 1 on the same side as the corn cob outlet 35. The second collection box 37 is fixedly connected to the side wall of the support platform 1 on the same side as the downward end of the inclined strainer 31.

[0095] The above are merely preferred embodiments of the present invention and are 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 within the protection scope of the present invention.
