Description

Technical Field

[0001] This utility model relates to the field of threshing machine technology, specifically to a corn threshing machine. Background Technology

[0002] A corn thresher is a mechanical device used to thresh corn kernels. Corn threshers are characterized by high automation, strong safety, simple operation, and low energy consumption. In existing technology, corn threshers achieve threshing through a combination of "impact + rubbing" actions. Corn ears are fed into the machine through the feed inlet, and the threshing drum (with spikes or grooves) inside the machine rotates at high speed, generating impact and rubbing forces on the ears, causing the kernels to fall off the cob. The fallen kernels, broken cobs, and impurities are first filtered through a screen to separate most of the cob, and then airflow generated by a fan blows away light debris, dust, and other impurities, ultimately yielding clean corn kernels. However, traditional corn threshers only use a single threshing drum to thresh the corn. Multiple ears of corn roll and are rubbed inside the threshing drum. Due to the short rubbing time, unthreshed kernels may still remain on the cob of the thresher, which increases the labor required for subsequent personnel. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this utility model provide a corn threshing machine, which solves the technical problem that in the prior art, a single threshing drum threshes corn, the kneading time is short, and there may still be unthreshed kernels on the ear cob of the threshing machine, which increases the labor of relevant personnel.

[0004] According to one aspect, at least one embodiment of the present invention provides a corn thresher, including a housing, a first threshing chamber, a second threshing chamber, a connecting port, and a threshing mechanism. The first threshing chamber is disposed within the housing, and the second threshing chamber is disposed within the housing. The bottom end of the second threshing chamber has a plurality of discharge holes. The connecting port is disposed within the housing. The bottom of the first threshing chamber and the top of the second threshing chamber are connected through the connecting port. The mechanism is disposed on the housing and is used to knead the corn in the first threshing chamber and drive the corn through the connecting port into the second threshing chamber for further kneading.

[0005] Preferably, the threshing mechanism includes a drive shaft, a threshing drum, extraction teeth, and a drive assembly. The drive shaft is coaxially rotatably disposed in both the first threshing chamber and the second threshing chamber. The threshing drum is mounted on the drive shaft and is coaxially and fixedly connected to the threshing drum. Multiple sets of extraction teeth are arranged circumferentially on the threshing drum. Each set of extraction teeth includes multiple extraction teeth arranged along the axis of the threshing drum. The drive assembly is disposed on the housing and is used to simultaneously drive the two drive shafts to rotate.

[0006] Furthermore, the drive assembly includes a drive motor and a linkage assembly. The drive motor is mounted on the housing, and the output end of the drive motor is coaxially and fixedly connected to one end of the drive shaft that is rotatably connected in the first threshing chamber. The linkage assembly is disposed on the two drive shafts.

[0007] Furthermore, the linkage component includes a pulley and a drive belt, with the other end of the drive shaft coaxially and fixedly connected to the pulley, and the drive belt being tensioned and sleeved on the two pulleys.

[0008] As a further aspect of this application, in order to facilitate the feeding of corn into the first threshing chamber, a feed inlet is connected to the top of the first threshing chamber, and the feed inlet and the connecting inlet are respectively located at both ends of the shell.

[0009] As a further aspect of this application, in order to enable the multiple threshing teeth to knead the corn during rotation and move the corn, the threshing teeth are arranged at an angle, with the threshing teeth in the first threshing chamber tilted towards the connecting opening.

[0010] Based on the aforementioned scheme, in order to transfer the ear cob in the second threshing chamber out of the shell, the shell is provided with a discharge port, which is located below the inlet, and the discharge port is semi-circular and communicates with the second threshing chamber.

[0011] Furthermore, in order to prevent corn kernels from moving out of the shell through the discharge port and to prevent the cob from moving out of the shell, a rotating shaft is fixedly provided at the discharge port. A baffle is sleeved on the outside of the rotating shaft and is coaxially fixedly connected to the baffle. The pulling teeth in the second threshing chamber are inclined towards the discharge port.

[0012] The beneficial effects of this utility model are as follows: In this invention, through the cooperation of the first threshing chamber, the second threshing chamber, the connecting port, and the threshing mechanism, the drive motor drives multiple pulling teeth located in the first and second threshing chambers to rotate. Corn is transferred into the first threshing chamber through the discharge port. Multiple ears of corn entering the first threshing chamber are not only rubbed by the multiple pulling teeth, but also piled up and rolled within the first threshing chamber, squeezing each other to thresh the corn into cobs and kernels. The threshed corn is then pushed by the inclined pulling teeth to the connecting port and into the second threshing chamber. After being rubbed again, the kernels are moved out of the shell through the discharge hole, while the cobs are conveyed towards the discharge port by the pulling teeth. The piled-up cobs push aside the baffle and move out of the shell. By providing the first and second threshing chambers, the corn undergoes a second rubbing, ensuring thorough threshing and preventing the cobs from still having some kernels attached, thus saving on subsequent processing work.

[0022] like Figures 1-5 As shown, it illustrates a corn thresher in one embodiment of the present invention, including a housing 1, with multiple support legs 2 at the bottom of the housing 1 for stable support of the housing 1, and also including a first threshing chamber 3, a second threshing chamber 4, a connecting port 6, and a threshing mechanism. like Figure 4As shown, a first threshing chamber 3 and a second threshing chamber 4 are provided inside the housing 1. The second threshing chamber 4 is located diagonally below the first threshing chamber 3. To facilitate the feeding of corn into the first threshing chamber 3, multiple discharge holes 5 are provided at the bottom of the second threshing chamber 4. A connecting port 6 is provided inside the housing 1, and the connecting port 6 is inclined. The bottom of the first threshing chamber 3 and the top of the second threshing chamber 4 are connected through the connecting port 6. The top of the first threshing chamber 3 is connected to an inlet 13. The inlet 13 and the connecting port 6 are located at opposite ends of the housing 1. The first threshing chamber 3, the connecting port 6, the second threshing chamber 4, and the discharge port 14 are connected. In order to transfer the ear cob in the second threshing chamber 4 out of the shell 1, the shell 1 is provided with a discharge port 14. The discharge port 14 is located below the feed port 13. The discharge port 14 is semi-circular and connected to the second threshing chamber 4. In order to prevent the corn kernels from moving out of the shell 1 through the discharge port 14 and to prevent the ear cob from moving out of the shell 1, a rotating shaft 15 is fixedly provided on the discharge port 14. A baffle 16 is sleeved on the outside of the rotating shaft 15 and is coaxially fixedly connected to the baffle 16. The pulling teeth 9 in the second threshing chamber 4 are inclined towards the discharge port 14. like Figure 3 , Figure 4 and Figure 5 As shown, the kneading mechanism is installed on the housing 1 and is used to knead the corn in the first threshing chamber 3 and drive the corn through the connecting port 6 into the second threshing chamber 4 for further kneading. The threshing mechanism includes a drive shaft 7, a threshing drum 8, pulling teeth 9 and a drive assembly. The drive shaft 7 is coaxially rotatably installed in both the first threshing chamber 3 and the second threshing chamber 4. The threshing drum 8 is mounted on the drive shaft 7 and is coaxially fixedly connected to the threshing drum 8. Multiple sets of pulling teeth 9 are arranged circumferentially on the threshing drum 8. Each set of pulling teeth 9 includes multiple pulling teeth 9 arranged along the axis of the threshing drum 8. In order to make the multiple pulling teeth 9 knead the corn and drive the corn to move during rotation, the pulling teeth 9 are arranged at an angle. The pulling teeth 9 in the first threshing chamber 3 are inclined towards the connecting port 6, and the multiple pulling teeth 9 in the second threshing chamber 4 are inclined towards the discharge port 14. A drive assembly is mounted on the housing 1 and is used to simultaneously drive two drive shafts 7 to rotate. The drive assembly includes a drive motor 10 and a linkage assembly. The drive motor 10 is mounted on the housing 1, and its output end is coaxially and fixedly connected to one end of the drive shaft 7 rotatably connected in the first threshing chamber 3. The linkage assembly is mounted on the two drive shafts 7 and includes a pulley 11 and a drive belt 12. The other end of the drive shaft 7 is coaxially and fixedly connected to the pulley 11, and the drive belt 12 is tensioned and sleeved on the two pulleys 11. Specifically, by starting the drive motor 10, the output end of the drive motor 10 drives the drive shaft 7 in the first threshing chamber 3 to rotate. The drive shaft 7 drives the pulley 11 connected to it to rotate, and the rotation of the pulley 11 drives the sleeve... Drive belts 12 mounted on two pulleys 11 drive the other pulley 11 and drive shaft 7 to rotate. The other drive shaft 7 drives multiple pulling teeth 9 in the second threshing chamber 4 to rotate, transferring corn into the first threshing chamber 3 through the discharge port 14. Multiple corn kernels entering the first threshing chamber 3 are not only rubbed by multiple pulling teeth 9, but also piled up and rolled in the first threshing chamber 3, squeezing each other, so that the corn kernels are threshed into cobs and corn kernels. The threshed corn is pushed by the inclined pulling teeth 9 to the connecting port 6 and pushed into the second threshing chamber 4. After being rubbed again, the corn kernels are moved out of the shell 1 through the discharge hole 5, while the cobs are conveyed towards the discharge port 14 by the pulling teeth 9. The piled cobs push open the baffle 16 and move the shell 1. It should be added that before the corn thresher threshes the corn, a container for loading corn kernels needs to be placed at the bottom of the second threshing chamber 4, and a container for loading cobs needs to be placed on one side of the discharge port 14, so as to facilitate sorting and easy handling. Working Principle: During operation, the corn thresher 1 is placed on a stable working surface by support legs 2. A container for loading corn kernels is placed at the bottom of the second threshing chamber 4, and a container for loading cobs is placed on one side of the discharge port 14. By starting the drive motor 10, the output of the drive motor 10 drives the drive shaft 7 in the first threshing chamber 3 to rotate. This drive shaft 7 drives the connected pulley 11 to rotate. The rotation of the pulley 11 drives the drive belt 12 mounted on the two pulleys 11. The drive belt 12 drives the other pulley 11 and the drive shaft 7 to rotate. The other drive shaft 7 drives multiple teeth 9 in the second threshing chamber 4 to rotate, thus discharging the corn kernels. Corn is transferred from the opening 14 into the first threshing chamber 3. Multiple ears of corn entering the first threshing chamber 3 are not only rubbed by multiple pulling teeth 9, but also piled up and rolled in the first threshing chamber 3, squeezing each other, so that the corn is threshed into cobs and corn kernels. The threshed corn is pushed by the inclined pulling teeth 9 to the connecting opening 6 and pushed into the second threshing chamber 4. After being rubbed again, the corn kernels are moved out of the shell 1 through the discharge hole 5, while the cobs are conveyed towards the discharge opening 14 by the pulling teeth 9. The piled cobs push open the baffle 16 and move the shell 1. By setting the first threshing chamber 3 and the second threshing chamber 4, the corn is rubbed a second time, so that the corn is fully threshed and the situation where the cob still has some corn kernels is avoided, saving subsequent processing work.
