Abstract
Description
Technical Field
[0001] This application relates to the field of agricultural machinery technology, and in particular to a threshing device for corn seed processing. Background Technology
[0002] Agricultural machinery is becoming increasingly common, and small corn threshers for home use are also becoming more prevalent. As the name suggests, a corn thresher removes the kernels from the corn cob. Most corn threshers operate by using a high-speed rotating threshing drum with threshing teeth to rub and impact the corn cob, causing the kernels to fall off. Traditionally, farmers thresh corn by hand, a method that is not only inefficient but also causes hand pain afterward. The advent of corn threshers has effectively solved these problems. However, most current corn threshers perform only one threshing cycle, which cannot guarantee thorough threshing. Therefore, there is a need for an automatic thresher with high threshing efficiency to meet market demand. Utility Model Content
[0003] To address the shortcomings of existing technologies, this application provides a threshing device for corn seed processing, which has a good threshing effect, thorough threshing, and is fully automated, saving time and labor.
[0004] This application provides a threshing device for corn seed processing, which adopts the following technical solution:
[0005] A corn seed threshing device includes a shell, a rotating device disposed inside the shell, and a threshing ramp disposed on the inner side of the shell. The shell is characterized by being hollow, with a feed inlet at the top and a discharge outlet at the bottom. The rotating device includes a rotating shaft, a first rotating roller, a second rotating roller, and a rotating motor. The rotating motor is fixed to the bottom of the shell, and its output shaft is fixedly connected to the rotating shaft. The first and second rotating rollers have threshing teeth on their outer circumferences. The second rotating roller is frustum-shaped. The threshing ramp is located on the side opposite to the rotating device, and its outer surface has several separating teeth. The threshing ramp slopes from the feed inlet towards the discharge outlet.
[0006] By adopting the above technical solution, corn is put into the feed inlet, and the first rotating roller drives the corn to rotate, contacting the separating teeth on the threshing slope to separate the corn kernels. The corn cobs after initial separation enter the second rotating roller. The structure of the second rotating roller gradually reduces the distance between the second rotating roller and the threshing slope, improving the efficiency of corn kernel separation and making the separation more thorough. Then the corn cobs are discharged from the discharge outlet.
[0007] Optionally, the threshing slope is divided into an inclined upper part and an inclined lower part, the inclined upper part and the inclined lower part are elastically connected, and the inclined upper part is fixedly connected to the inner wall.
[0008] By adopting the above technical solution, the cooperation between the inclined upper part and the first rotating roller realizes the initial peeling of the corn cob, and the cooperation between the inclined lower part and the second rotating roller realizes the complete separation. The inclined lower part is elastically set to meet the threshing operation of corn cobs of different thicknesses.
[0009] Optionally, the inclined upper part and the inclined lower part are provided with separation teeth.
[0010] By adopting the above technical solution, the separating teeth mainly serve to cooperate with the rotating device to achieve the separation of corn kernels.
[0011] Optionally, the bottom of the housing is also provided with a through hole.
[0012] By adopting the above technical solution, the through hole is used for discharging the peeled corn kernels, which fall into the storage box below.
[0013] Optionally, a fixing mechanism is provided on the outer wall of the housing, the fixing mechanism including a fixing seat and screws and nuts.
[0014] By adopting the above technical solution, the fixing mechanism uses a fixing seat to fix the detachment device, and can be fixed to desktops, workbenches, etc.
[0015] Optionally, the threshing teeth are arranged in a spiral shape on the outer side of the first rotating roller and the second rotating roller.
[0016] By adopting the above technical solution, the threshing teeth are arranged in a spiral shape, and the spiral arrangement takes advantage of the downward movement of the corn.
[0017] Optionally, a storage box is provided below the discharge port.
[0018] By adopting the above technical solution, the storage box collects the peeled corn kernels and corn cobs.
[0019] In summary, the beneficial technical effects of this application are as follows: the first rotating roller drives the corn to rotate and contact the separating teeth on the threshing slope to achieve the separation of corn kernels. The corn cobs after initial separation enter the second rotating roller. The second rotating roller has a frustum structure, which gradually reduces the distance between the second rotating roller and the threshing slope, thereby improving the efficiency of corn kernel separation and making the separation more thorough.

[0027] Reference Figure 1-3A corn seed threshing device includes a shell 1, a rotating device disposed within the shell 1, and a threshing ramp 2 disposed on the inner side of the shell 1. The shell 1 is hollow, with a feed inlet 3 at the top and a discharge outlet 4 at the bottom. The rotating device includes a rotating shaft, a first rotating roller 5, a second rotating roller 6, and a rotating motor 7. The rotating motor 7 is fixed to the bottom of the shell 1, and its output shaft is fixedly connected to the rotating shaft. The first rotating roller 5 and the second rotating roller 6 have threshing teeth on their outer circumferences. The threshing slope 2 is shaped like a frustum and is located on the side opposite to the rotating device. The outer surface of the threshing slope 2 is provided with several separating teeth 8. The threshing slope 2 is inclined from the feed inlet 3 to the discharge outlet 4. Corn is put into the feed inlet 3 and rotated by the first rotating roller 5. The corn comes into contact with the separating teeth 8 on the threshing slope 2 to separate the corn kernels. The corn cobs after initial separation enter the second rotating roller 6. The structure of the second rotating roller 6 gradually reduces the distance between the second rotating roller 6 and the threshing slope 2, improving the efficiency of corn kernel separation and making the separation more thorough. Then the corn cobs are discharged from the discharge outlet 4.
[0028] Reference Figure 4 The threshing ramp 2 is divided into an upper inclined part 9 and a lower inclined part 10. The upper inclined part 9 and the lower inclined part 10 are elastically connected. The upper inclined part 9 is fixed to the inner wall. The cooperation between the upper inclined part 9 and the first rotating roller 5 realizes the initial peeling of the corn cobs. The cooperation between the lower inclined part 10 and the second rotating roller 6 realizes complete separation. The lower inclined part 10 is elastically set to meet the threshing operation of corn cobs of different thicknesses.
[0029] Separation teeth 8 are provided on the inclined upper part 9 and the inclined lower part 10. The separation teeth 8 mainly serve to cooperate with the rotating device to achieve the separation of corn kernels.
[0030] The bottom of the outer shell 1 is also provided with a through hole 11, which is used for discharging the peeled corn kernels into the storage box below.
[0031] A fixing mechanism 12 is provided on the outer wall of the outer casing 1. The fixing mechanism 12 includes a fixing seat and screws and nuts. The fixing mechanism 12 uses the fixing seat to fix the detachment device and can be fixed to the desktop, workbench, etc.
[0032] The threshing teeth are arranged in a spiral shape on the outside of the first rotating roller 5 and the second rotating roller 6. The spiral arrangement of the threshing teeth takes advantage of the downward movement of the corn.
[0033] A collection box is provided below the discharge port 4 to collect the peeled corn kernels and corn cobs.
[0034] During use, corn is fed into the feed inlet 3. The first rotating roller 5 drives the corn to rotate and contact the separating teeth 8 on the threshing slope 2. The separating teeth 8 are fixed. Under the drive of the first rotating roller 5, the corn kernels are separated. The corn cobs after initial separation enter the second rotating roller 6. The second rotating roller 6 is thinner at the top and thicker at the bottom, so that the distance between the second rotating roller 6 and the threshing slope 2 gradually decreases. With the help of the separating teeth 8 at the inclined lower part 10, the efficiency of corn kernel separation is improved and the separation is more thorough. Then the corn cobs are discharged from the discharge outlet 4.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. The best standard is to achieve the operation of this utility model. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the scope of protection of this application.
