The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides a corn threshing device that is convenient for receiving materials, such as... Figure 1-5As shown, the convenient corn threshing device includes: a threshing box 1, which is used to thresh corn; two threshing rollers 2 rotatably mounted on the threshing box 1, which are used to thresh corn, and each of the two threshing rollers 2 is fixedly fitted with a spur gear 3, which meshes with each other; a motor 4 fixedly mounted at the bottom of the threshing box 1, and two first pulleys 5 fixedly fitted on the output shaft of the motor 4 and one of the threshing rollers 2, respectively, with a first belt 6 fitted on the two first pulleys 5; and a receiving pipe 7 fixedly mounted on the threshing box 1, which is used to receive the threshed corn kernels, and a positioning mechanism 8 is provided on the receiving pipe 7 to fix the bag for receiving the corn kernels.

[0024] In this embodiment, when threshing corn, the bag opening for collecting corn kernels is first placed on the receiving pipe 7, and then the bag opening is fixed on the receiving pipe 7 by the positioning mechanism 8. This facilitates the receiving and bagging of the threshed corn kernels, eliminating the need for workers to process the corn kernels separately afterward. This provides convenience for workers, reduces the overall operational burden, and improves the overall efficiency of corn threshing.

[0025] The motor 4 is started by the controller. Under the interaction of the first pulley 5, the first belt 6, and the spur gear 3, the two threshing rollers 2 are driven to rotate relative to each other. Friction is generated between the rotating threshing rollers 2 and the corn cobs with corn kernels. Through friction and collision, the connection between the corn kernels and the corn cobs is broken, thereby threshing the corn. Most of the threshed corn kernels fall onto the guide mesh plate 10 and are then discharged into the receiving bag through the receiving pipe 7, thus completing the threshing and collection of the corn.

[0026] In a further preferred embodiment of the present invention, the positioning mechanism 8 includes: a mounting bracket 801 fixedly installed on the outside of the receiving pipe 7; a lead screw 802 slidably disposed on the mounting bracket 801; a clamping ring 803 fixedly installed on the lead screw 802, the clamping ring 803 being adapted to the outer wall of the receiving pipe 7; and a nut 804 threadedly sleeved on the lead screw 802.

[0027] In this embodiment, when using the positioning mechanism 8, the bag opening for collecting corn kernels is placed on the receiving pipe 7. Then, the lead screw 802 is moved so that the clamping ring 803 abuts against the outer wall of the receiving pipe 7. After determining the position of the lead screw 802 on the mounting frame 801, the nut 804 is rotated so that one side of the nut 804 abuts against one side wall of the mounting frame 801. This prevents the clamping ring 803 (which has a rubber pad to increase the friction between the clamping ring 803 and the bag) from displacing away from the receiving pipe 7, thus stably connecting the bag opening and the receiving pipe 7. This facilitates the receiving and bagging of the corn kernels, eliminating the need for workers to perform separate processing of the corn kernels afterward, providing convenience for workers and improving the overall efficiency of the corn threshing operation.

[0028] In a further preferred embodiment of this utility model, a sieve plate 9 is fixedly installed on the threshing box 1. The sieve plate 9 is used to screen the threshed corn cobs and some of the corn kernels. A guide mesh plate 10 is fixedly installed on the threshing box 1. The guide mesh plate 10 is used to guide the threshed corn kernels into the receiving pipe 7. The threshing box 1 is provided with a vibration mechanism for vibrating and screening the guide mesh plate 10.

[0029] In this embodiment, after the corn is threshed, the corn cob is discharged by the screen plate 9, and some corn kernels mixed in with the threshed corn cob pass through the screen plate 9 and fall into the receiving pipe 7. At the same time, most of the corn kernels are guided into the receiving pipe 7 by the guide mesh plate 10.

[0030] In a further preferred embodiment of the present invention, the vibration mechanism includes: a mounting shaft 11 rotatably mounted on the threshing box 1; a cam 12 fixedly mounted on the mounting shaft 11, the cam 12 being located below the guide mesh plate 10; and two second pulleys 13 respectively fixedly sleeved on the mounting shaft 11 and the output shaft of the motor 4, with a second belt 14 sleeved on the two second pulleys 13.

[0031] In this embodiment, when the motor 4 is in use, the interaction between the second pulley 13 and the second belt 14 drives the cam 12 on the mounting shaft 11 to rotate and vibrate the guide screen plate 10, thereby pre-screening some small impurities in the corn kernels that have been removed, pre-processing the corn kernels to remove impurities, and improving the cleanliness of the corn kernels.

[0032] In a further preferred embodiment of this utility model, the receiving pipe 7 has two installation ports, and each of the two installation ports is provided with a partition net 701. The threshing box 1 and the receiving pipe 7 are provided with a cleaning mechanism, which is used to remove impurities from the corn kernels fed into the receiving pipe 7.

[0033] In this embodiment, the partition 701 facilitates the removal of impurities from the corn inside the feed pipe 7.

[0034] In a further preferred embodiment of the present invention, the impurity removal mechanism includes: a placement shaft 15 rotatably mounted on the outer wall of one side of the receiving pipe 7; a fan blade 16 fixedly mounted on the placement shaft 15, the fan blade 16 being located on one side of the mounting port; and two third pulleys 17 respectively fixedly sleeved on the placement shaft 15 and one of the threshing rollers 2, with a third belt 18 sleeved on the two third pulleys 17.

[0035] In this embodiment, when the threshing roller 2 rotates, the interaction between the third pulley 17 and the third belt 18 drives the fan blade 16 on the placement shaft 15 to rotate. The rotating fan blade 16 generates wind, thereby performing wind separation and impurity removal operation on some impurities in the corn kernels fed into the receiving pipe 7. The cleaned impurities pass through the partition 701 and move out of the receiving pipe 7, improving the cleanliness of the corn kernels.

[0036] In a further preferred embodiment of this utility model, a guide frame 19 is fixedly installed on the threshing box 1. The guide frame 19 is located on one side of the screen plate 9. The guide frame 19 is used to guide the corn cobs after threshing. A controller is provided on the threshing box 1. The controller is used to perform control operations.

[0037] In this embodiment, the guide frame 19 is used to guide the threshed corn cobs, and the controller facilitates the operation.

[0038] In summary, compared with related technologies, the corn threshing device, which consists of a threshing box 1, a threshing roller 2, a spur gear 3, a motor 4, a first pulley 5, a first belt 6, a receiving pipe 7, a positioning mechanism 8, a vibration mechanism, a partition net 701, a cleaning mechanism, a guide frame 19, and a controller, is designed for convenient receiving of corn kernels. It can thresh corn and facilitate the receiving and bagging of the threshed kernels, eliminating the need for workers to perform separate processing of the kernels afterward. This provides convenience for workers and improves the overall efficiency of corn threshing operations.
