Description

Technical Field

[0001] The utility model relates to the technical field of corn thresher accessories, and specifically relates to a threshing bin for a corn thresher. Background Technique

[0002] A corn thresher refers to a mechanical device for threshing corn ears. The corn thresher has the characteristics of high automation, strong safety, simple operation, low energy consumption, etc. As the name implies, the threshing bin for a corn thresher is a threshing bin chamber used on a corn thresher to realize the corn threshing work.

[0003] However, the commonly seen threshing bins for corn threshers on the market still have some deficiencies in the actual use process. For example: Although the commonly seen threshing bins for corn threshers on the market can quickly thresh corn during the actual use process, the threshed corn kernels are not easy to collect, and the corn cobs are placed randomly on the ground, causing great trouble to the subsequent work. The internal structures of some threshers are relatively simple, and are prone to damage of the internal structures under the interference of dust for a long time. Once damaged, the whole needs to be replaced. Content of the Utility Model

[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: a threshing bin for a corn thresher, including a threshing bin main body 1, a transmission shaft 2 is rotatably installed inside the threshing bin main body 1, a first roller component 3 and a second roller component 4 are fixedly installed on the surface of the transmission shaft 2, and first dust-proof sealing components 5 and second dust-proof sealing components 6 are fixedly installed at both ends of the first roller component 3 and the second roller component 4 respectively. Both the first dust-proof sealing component 5 and the second dust-proof sealing component 6 include a metal connecting ring 51. The metal connecting ring 51 is fixedly connected to the end faces of the first roller component 3 and the second roller component 4 through long-neck connecting bolts 52. One side of the metal connecting ring 51 is fixedly connected with a bearing component 53. One end of the bearing component 53 is fixedly connected with a dust-proof sleeve 54. A dust-proof brush ring 55 is arranged inside one end of the dust-proof sleeve 54. During daily use, the first dust-proof sealing component 5 and the second dust-proof sealing component 6 arranged at both ends of the transmission shaft 2 can effectively achieve dust-proofing of structures such as the transmission shaft 2, and can effectively avoid damage to bearings and shaft-like structures caused by dust. Moreover, by assembling the transmission shaft 2, the first roller component 3, and the second roller component 4 with bolts, it is convenient for staff to maintain and repair some damaged parts, avoiding the problem that the traditional such devices need to be replaced as a whole once damaged.

[0020] Among them, the first roller component 3 and the second roller component 4 are combined into a cylindrical shape, and the threshing teeth 9 are fixedly welded at the middle position of the surface of the first roller component 3 and the second roller component 4. The surfaces of the first roller component 3 and the second roller component 4 on both sides of the threshing teeth 9 are respectively welded with core plates 10 and spiral feeding blades 11. The spiral feeding blades 11 are responsible for transporting the corn that falls into the threshing bin. The threshing teeth 9 can facilitate the threshing of the corn, and the core plates 10 continuously put the threshed corn cobs into the inside of the core through holes 18.

[0021] Among them, a connecting component 7 is fixedly installed on the surface of the transmission shaft 2 on one side of the spiral feeding blade 11, and a pulley mechanism 8 is fixedly connected to the connecting component 7. One end of the pulley mechanism 8 is fixedly connected to the output end of the external motor. The external motor and one end of the transmission shaft 2 are connected through the pulley mechanism 8 to achieve efficient mechanical transmission.

[0022] Among them, the surfaces of the first roller component 3 and the second roller component 4 are provided with mounting holes 13 at equal intervals, and fastening bolts 14 are arranged at the mounting holes 13, and the surface of the transmission shaft 2 is provided with threaded connection holes 12 that cooperate with the mounting holes 13 and the fastening bolts 14 at equal intervals. The transmission shaft 2, the first roller component 3, and the second roller component 4 are installed by bolt assembly, which makes it convenient for the staff to maintain and repair some damaged parts, avoiding the problem that traditional devices of this type need to be replaced as a whole once they are damaged.

[0023] Among them, a grid plate 17 is arranged inside the threshing bin main body 1 outside the transmission shaft 2, and a feed hopper 19 is arranged at the top of the threshing bin main body 1 above the spiral feeding blade 11. The setting of the feed hopper 19 is mainly used to facilitate the user to feed the corn cobs to be threshed into the threshing bin.

[0024] Among them, a feed shell 15 is fixedly arranged at the bottom of the threshing bin main body 1, and one side of the feed shell 15 is interconnected with the core row plate 10 through the core row through hole 18. A discharge through hole 16 is arranged at the bottom of the feed shell 15, and the bottom of the grid plate 17 is connected to the feed shell 15. By automatically classifying and collecting corn kernels and corn cobs after threshing, efficient threshing is achieved and subsequent processing is more convenient, thereby greatly improving work efficiency.

[0025] Working principle: Before use, first check the safety of the various components inside the threshing bin, then fix the threshing bin on the thresher, connect one end of the pulley mechanism 8 to the connecting component 7, and the other end to the external motor, and then start using the threshing bin;

[0026] When the thresher is working, the user first starts the external motor, so that the motor drives the transmission shaft 2 to rotate at a high speed through the pulley mechanism 8, and then puts the corn cobs to be threshed into the threshing chamber main body 1 through the feed hopper 19. At this time, the corn cobs move towards the threshing teeth 9 under the drive of the spiral feeding paddle 11 and carry out the threshing work. The threshed corn kernels fall into the inside of the material conveying housing 15 through the gaps of the grid plate 17 and are discharged and collected through the outlet on one side of the discharge through hole 16. The threshed corn cobs are driven to the core discharge plate 10 again, and are discharged into the core discharge through hole 18 through the core discharge plate 10, and fall into the material conveying housing 15 through the core discharge through hole 18, and finally are discharged through the outlet on the other side of the material conveying housing 15;

[0027] During daily use, the first dust-proof sealing assembly 5 and the second dust-proof sealing assembly 6 provided at both ends of the transmission shaft 2 can effectively achieve dust-proofing of structures such as the transmission shaft 2, and can effectively avoid damage to bearings and shaft-like structures caused by dust. Moreover, by assembling the transmission shaft 2, the first drum component 3, and the second drum component 4 with bolts, it is convenient for the staff to maintain and repair some damaged parts, and avoid the problem that the whole device needs to be replaced once it is damaged in the traditional such devices.
