Abstract
Description
Technical Field
[0001] This utility model relates to the field of corn threshing technology, specifically to a corn seed thresher. Background Technology
[0002] Corn threshing is mostly done manually, which is slow, tiring, and can easily injure the hands. Therefore, a corn threshing machine was designed, which can separate the whole corn kernel during use.
[0003] The existing technology has the following problems:
[0004] Existing corn threshers often fail to effectively remove the corn seeds from the surface of corn cobs of varying sizes, leaving some seeds still attached. To facilitate threshing, corn is often sun-dried to harden the seeds, but this process leaves a large amount of dust and impurities on the surface. If not cleaned promptly, this can lead to difficulty in controlling temperature and humidity during storage, resulting in the seeds rotting and spoiling. Utility Model Content
[0005] This invention provides a corn seed thresher to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A corn seed thresher includes a thresher body, a dust removal chamber fixedly connected to the bottom of the thresher body, a feed inlet opened at the top of the thresher body, an electric telescopic rod fixedly connected to the left side of the inner wall of the thresher body, a fixed frame fixedly connected to the output end of the electric telescopic rod, and a thresher mechanism provided on the inner wall of the fixed frame.
[0008] The threshing mechanism includes a first motor fixedly connected to one side of the inner wall of the fixed frame, a reverse gear fixedly connected to the output end of the first motor, a toothed disc meshing on one side of the reverse gear, and a threshing roller fixedly connected to one side of the outer wall of the toothed disc.
[0009] A discharge port is provided at one end of the bottom of the inner wall of the dust removal chamber, and a dust storage chamber is slidably connected to the other end of the bottom of the inner wall of the dust removal chamber away from the discharge port.
[0010] A further improvement of the present invention is that the inner cavity of the threshing roller is provided with a plurality of sliding grooves, and the inner wall of the sliding groove is slidably connected with a threshing top block.
[0011] A further improvement of the present invention is that: a pulley is connected between the first motor and the reverse gear, a fixed rod is connected to one end of the pulley, and an irregularly shaped lever is fixedly connected to the center of the surface of the fixed rod.
[0012] A further improvement of this utility model is that a groove is provided on the side of the threshing body away from the electric telescopic rod, and an electric track is fixedly connected to the inner cavity of the groove.
[0013] A further improvement of this utility model is that: several electric fans are fixedly connected to the middle of the right side of the inner wall of the dust removal chamber, and an elastic screen is fixedly connected to the side of the dust removal chamber away from the electric fans.
[0014] A further improvement of this utility model is that a second motor is fixedly connected to the middle of one side of the inner wall of the dust removal chamber, and a lever is fixedly connected to the output end of the second motor. One end of the lever overlaps with one end of the bottom of the elastic screen.
[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0016] 1. This utility model provides a corn seed thresher. A pulley is installed between a first motor and a reverse gear. The pulley drives a fixed rod at one end. A shaped paddle is located at the center of the fixed rod's surface. This causes the threshing roller and the shaped paddle to rotate in opposite directions under the drive of the reverse gear. During rotation, the protrusion of the shaped paddle contacts the bottom of the threshing top block, pushing the top block out of the threshing roller and allowing its top to contact the corn, thus peeling off the seeds from the corn surface. This solves the problem of traditional corn seed threshing devices often failing to effectively remove seeds from corn cobs of varying sizes, resulting in some seeds remaining on the cob and causing unnecessary waste.
[0017] 2. This utility model provides a corn seed thresher. By feeding the separated corn cobs and seeds onto an elastic screen, a second motor is started, driving a lever at its output end to move the elastic screen, causing it to vibrate at high frequency. This separates the dust and impurities on the surface of the corn cobs and seeds. When the corn cobs and seeds fall from the elastic screen, a fan blows the dust and impurities attached to their surfaces into a dust storage bin, while the corn seeds and cobs are discharged through the discharge port. This solves the problem that traditional corn seed threshing devices cannot separate the dust and impurities attached to the surface of corn seeds and cobs during use, which would otherwise require additional screening of the corn seeds.

[0025] The present invention will be further described in detail below with reference to embodiments:
[0026] Example 1
[0027] like Figure 1-6 As shown, this utility model provides a corn seed thresher, including a threshing body 1, a dust removal chamber 2 fixedly connected to the bottom of the threshing body 1, a feed inlet 3 opened at the top of the threshing body 1, an electric telescopic rod 4 fixedly connected to the left side of the inner wall of the threshing body 1, a fixed frame 5 fixedly connected to the output end of the electric telescopic rod 4, a threshing mechanism fixedly connected to the inner wall of the fixed frame 5, the threshing mechanism including a first motor 6 fixedly connected to one side of the inner wall of the fixed frame 5, a reverse gear 7 fixedly connected to the output end of the first motor 6, a gear plate 8 meshing on one side of the reverse gear 7, a threshing roller 9 fixedly connected to one side of the outer wall of the gear plate 8, a discharge port 10 opened at one end of the bottom of the inner wall of the dust removal chamber 2, and a dust storage chamber 11 slidably connected to the end of the bottom of the inner wall of the dust removal chamber 2 away from the discharge port 10.
[0028] In this embodiment, corn is fed into the feed inlet 3 at the top of the threshing body 1. The electric telescopic rod 4 is activated, causing the fixed frame 5 at its output end to move to the lower right. Threshing rollers 9 are installed on the inner wall of the fixed frame 5, which block the corn inside the threshing body 1. At this time, the first motor 6 is activated. A reverse gear 7 is installed at the output end of the first motor 6, which drives a toothed disc 8 on one side. As the toothed disc 8 rotates, it drives the threshing rollers 9 on one side of its outer wall. The surface of the corn is uneven, and the corn cob is rubbed against the surface of the corn through the uneven gaps, so that the corn seeds fall into the dust removal chamber 2 through the gap between the threshing roller 9 and the threshing body 1. After the seeds on the surface of the corn are removed, the corn cob falls into the dust removal chamber 2 through the threshing body 1. The electric fan 19 and the elastic screen 20 are used to remove the dust and impurities from the corn seeds. The debris is carried by the airflow into the dust storage chamber 11 for storage, while the corn seeds and corn cob are discharged and collected through the discharge port 10.
[0029] Example 2
[0030] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the inner cavity of the threshing roller 9 is provided with a plurality of sliding grooves 12, the inner wall of the sliding groove 12 is slidably connected to a threshing top block 13, the first motor 6 is driven to be connected to the reverse gear 7 by a pulley 14, one end of the pulley 14 is driven to be connected to a fixed rod 15, and a special-shaped paddle block 16 is fixedly connected to the center of the surface of the fixed rod 15.
[0031] In this embodiment, several grooves 12 are provided in the inner cavity of the threshing roller 9, and a threshing top block 13 is provided on the inner wall of the groove 12. A pulley 14 is provided between the first motor 6 and the reverse gear 7. The pulley 14 drives the fixed rod 15 provided at one end. Since a special-shaped paddle 16 is provided at the center of the surface of the fixed rod 15, the threshing roller 9 and the special-shaped paddle 16 rotate in opposite directions under the drive of the reverse gear 7. At the same time, during the rotation of the special-shaped paddle 16, its protrusion will contact the bottom of the threshing top block 13, thereby pushing the threshing top block 13 out of the threshing roller 9, so that the top of the threshing top block 13 contacts the corn, thereby peeling off the seeds on the surface of the corn. This solves the problem that traditional corn seed threshing devices often cannot effectively peel off the corn seeds on the surface of corn cobs with large differences in size, resulting in some corn seeds still adhering to the corn cob, thus causing unnecessary waste.
[0032] Example 3
[0033] like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a groove 17 is provided on the side of the threshing body 1 away from the electric telescopic rod 4, and an electric track 18 is fixedly connected to the inner cavity of the groove 17.
[0034] In this embodiment, a groove 17 is provided on the side of the threshing body 1 away from the electric telescopic rod 4, and an electric track 18 is provided in the inner cavity of the groove 17. When the corn cob enters the threshing body 1, the electric track 18 drives the corn cob and the threshing roller 9 to rotate in opposite directions, thereby greatly increasing the friction between the corn cob and the threshing roller 9, so that the corn seeds on the surface of the corn cob can be threshed more thoroughly.
[0035] Example 4
[0036] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a plurality of electric fans 19 are fixedly connected to the middle of the right side of the inner wall of the dust removal chamber 2, an elastic screen 20 is fixedly connected to the side of the dust removal chamber 2 away from the electric fans 19, a second motor 21 is fixedly connected to the middle of one side of the inner wall of the dust removal chamber 2, a lever 22 is fixedly connected to the output end of the second motor 21, and one end of the lever 22 overlaps with one end of the bottom of the elastic screen 20.
[0037] In this embodiment, by installing an electric fan 19 in the middle of the right side of the inner wall of the dust removal chamber 2, when the separated corn cobs and corn seeds fall into the elastic screen 20, the second motor 21 is started, driving the lever 22 installed at its output end to move the elastic screen 20, thereby causing the elastic screen 20 to vibrate at high frequency, so that the dust and impurities on the surface of the corn cobs and corn seeds are separated. When the corn cobs and corn seeds fall from the elastic screen 20, the electric fan 19 blows the dust and dirt attached to the surface of the corn cobs and corn seeds into the dust storage chamber 11, while the corn seeds and corn cobs are discharged through the discharge port 10. This solves the problem that traditional corn seed separation devices cannot separate the dust and impurities attached to the surface of corn seeds and corn cobs during use, which leads to the need for additional screening of corn seeds in the future.
[0038] The working principle of this corn seed thresher will be explained in detail below.
[0039] like Figure 1-6As shown, by feeding corn into the feed inlet 3 at the top of the threshing body 1, the electric telescopic rod 4 is activated, causing the fixed frame 5 at its output end to move to the lower right. Threshing rollers 9 are installed on the inner wall of the fixed frame 5, blocking the corn within the threshing body 1. At this time, the first motor 6 is activated, and a reverse gear 7 is installed at the output end of the first motor 6. The reverse gear 7 drives a toothed disc 8 on one side. As the toothed disc 8 rotates, it drives the threshing roller 9 on one side of its outer wall. Simultaneously, several grooves 12 are installed in the inner cavity of the threshing roller 9, and threshing top blocks 13 are installed on the inner wall of the grooves 12. A belt is installed between the first motor 6 and the reverse gear 7. The wheel 14, driven by a pulley 14, pulls a fixed rod 15 at one end. Because a shaped paddle 16 is located at the center of the fixed rod 15, the threshing roller 9 and the shaped paddle 16 rotate in opposite directions under the drive of the reverse gear 7. Simultaneously, during rotation, the protrusion of the shaped paddle 16 contacts the bottom of the threshing top block 13, pushing the threshing top block 13 out of the threshing roller 9. This causes the top of the threshing top block 13 to contact the corn, thus peeling off the seeds from the surface of the corn. This solves the problem that traditional corn threshing devices often cannot effectively peel off the seeds from corn cobs of varying sizes. The separation process can lead to some corn seeds remaining attached to the corn cob, resulting in unnecessary waste. To address this, a groove 17 is provided on the side of the threshing body 1 furthest from the electric telescopic rod 4. An electric track 18 is installed inside the groove 17. When the corn cob enters the threshing body 1, the electric track 18 drives the corn cob and the threshing roller 9 to rotate in opposite directions, greatly increasing the friction between them. This allows the corn seeds on the surface of the corn cob to be threshed more thoroughly. The threshed corn seeds then fall into the dust collection chamber 2 through the gap between the threshing roller 9 and the threshing body 1. An electric fan 19 is installed in the middle of the right side of the inner wall of the dust collection chamber 2. When the separated corn cob and the dust collection chamber 2 are separated, the electric track 18 drives the corn cob and the threshing roller 9 to rotate in opposite directions, greatly increasing the friction between them. This allows the corn seeds on the surface of the corn cob to be threshed more thoroughly. When corn seeds fall into the elastic screen 20, the second motor 21 is started, driving the lever 22 at its output end to move the elastic screen 20, causing it to vibrate at high frequency. This separates the dust and impurities on the surface of the corn cob and corn seeds. When the corn cob and corn seeds fall from the elastic screen 20, the electric fan 19 blows the dust and impurities attached to the surface of the corn cob and corn seeds into the dust storage bin 11, while the corn seeds and corn cob are discharged through the discharge port 10. This solves the problem that traditional corn seed separation devices cannot separate the dust and impurities attached to the surface of corn seeds and corn cobs during use, which would otherwise require additional screening of the corn seeds.
[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
