[0002] Crops are the product of agriculture, which is an industry that uses the growth and development patterns of plants and animals to produce products through artificial cultivation. After harvesting, crops need to be further processed using equipment. Corn and wheat, as common crops, need to be threshed after harvesting, which requires the use of threshing machines.

[0003] A search revealed a double-drum thresher for easy collection, with application number 202421752718.1. This thresher uses a collection bag at the bottom of the discharge port to collect the kernels. The threshed kernels can be discharged from the outlet, and the corn kernels can enter the collection box. When collecting the material, the collection bag is removed from below the discharge port, and then the collection box is removed from the frame to achieve centralized collection, thus solving the problem of inconvenient collection.

[0004] However, the aforementioned thresher lacks a function for removing impurities from the corn kernels during actual use. This results in a significant amount of fine impurities mixed in with the corn kernels collected in the collection box, severely affecting the collection quality. Therefore, it is necessary to improve the thresher. Utility Model Content

[0005] To address the technical problem that existing double-drum threshers, which facilitate collection, lack the function of removing impurities from corn kernels, resulting in a large number of fine impurities mixed in with the collected corn, this utility model provides a double-drum thresher for easy collection.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification and the foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification or the foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] 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.

[0021] This utility model embodiment provides a threshing machine with dual drums for easy collection, such as... Figure 1-3 As shown, the double-drum thresher for easy collection includes: a double-drum thresher body comprising a frame 1, a thresher cylinder 2, a feed hopper 3, and a discharge port 4; a base plate 5 fixedly installed at the bottom of the frame 1, on which a fan 6 is fixedly installed; and a blower mechanism mounted on the fan 6 for removing impurities from the corn.

[0022] In the solution, the threshing machine body, which includes a frame 1, a threshing cylinder 2, a feed hopper 3, and a discharge port 4, is a prior art and its working principle is a publicly available technology. When in use, corn is first put into the feed hopper. The guide plates distributed inside the feed pipe can prevent all the corn from entering the threshing cylinder and causing blockage. The drive motor drives the drive wheel to rotate, and the drive wheel drives the driven wheel and the first drum to rotate through the belt. The first gear on the first drum meshes with the second gear, which can drive the second drum to rotate. The rotation of the first drum and the second drum can improve the threshing efficiency. The guide plates can achieve uniform feeding of corn. The corn cobs can be discharged from the cob discharge port. The collection bag at the bottom of the cob discharge port can collect the cobs. The threshed kernels can be discharged from the discharge port and the corn kernels can enter the collection box. When picking up the material, the collection bag is removed from below the cob discharge port, and then the collection box is removed from the frame to achieve centralized collection.

[0023] After the improvement of this solution, when the threshed corn kernels are discharged from the discharge port 4 during the working process, the blower 6 needs to be started at the same time. The wind force generated by the blower 6 acts on the corn kernels discharged from the discharge port 4 through the blowing mechanism. Since the weight of the corn kernels and the fine impurities mixed in them are different, the lighter fine impurities will be blown away from the corn kernels under the action of the wind force, thereby realizing the function of removing impurities from the corn kernels and effectively improving the collection quality of corn kernels.

[0024] In a further preferred embodiment of the present invention, the blower mechanism includes: a connecting pipe 7 fixedly installed on the exhaust end of the blower 6, a through pipe 8 fixedly installed on the connecting pipe 7, and an air diffuser 9 for blowing air fixedly installed at one end of the through pipe 8.

[0025] In this embodiment, the blower is used to remove impurities from the corn. During operation, when the corn kernels are discharged from the outlet 4, the blower 6 is started. The air force generated by the blower 6 enters the through pipe 8 through the connecting pipe 7, and is then diffused and blown out after passing through the air diffuser 9. The air diffuser 9 allows the air force to act more evenly and more widely on the corn kernels discharged from the outlet 4, thereby more effectively blowing away the fine impurities mixed in the corn kernels and improving the impurity removal effect.

[0026] In a further preferred embodiment of this utility model, the double-drum thresher for easy collection also includes a conveying mechanism installed on the base plate 5 for conveying corn.

[0027] In this embodiment, the use of a conveying mechanism allows corn to be fed into the feed hopper 3 from a low position, eliminating the need for people to drop corn from a high position and saving physical effort.

[0028] In a further preferred embodiment of the present invention, the conveying mechanism includes: a conveying cylinder 10 fixedly installed on the top of the base plate 5, a rotating shaft 13 rotatably installed on the inner wall of the conveying cylinder 10, the top end of the rotating shaft 13 extending to the outside of the conveying cylinder 10; a feeding hopper 11 fixedly installed on the conveying cylinder 10; a discharge pipe 12 fixedly installed on the conveying cylinder 10, the discharge pipe 12 being located above the feeding hopper 3; a spiral blade 14 fixedly sleeved on the rotating shaft 13, the spiral blade 14 being located inside the conveying cylinder 10; and a servo motor 15 fixedly installed on the top of the conveying cylinder 10, the output shaft of the servo motor 15 being fixedly connected to the top end of the rotating shaft 13.

[0029] In this embodiment, during operation, corn is placed into the feeding hopper 11, the servo motor 15 is started, the servo motor 15 drives the rotating shaft 13 to rotate, and the spiral blades 14 on the rotating shaft 13 rotate accordingly, lifting the corn from the feeding hopper 11 and conveying it to the discharge pipe 12, and finally falling into the feeding hopper 3 through the discharge pipe 12, thereby realizing the function of automatic feeding from low to high, reducing the intensity of manual labor.

[0030] In a further preferred embodiment of the present invention, a support frame 16 is fixedly installed on the outer wall of the threshing drum 2, and the bottom of the support frame 16 is fixedly connected to the connecting pipe 7.

[0031] In this embodiment, the use of the support frame 16 can improve the stability of the connecting pipe 7 during use, so as to prevent excessive shaking.

[0032] In a further preferred embodiment of this utility model, a wire mesh 17 is fixedly installed on the air diffuser 9, and the wire mesh 17 is used to block corn.

[0033] In this embodiment, the use of wire mesh 17 can prevent corn kernels discharged from the discharge port 4 from entering the ventilation hood 9.

[0034] In a further preferred embodiment of the present invention, a filter screen is fixedly installed on the air inlet end of the fan 6, and the filter screen is used to block impurities.

[0035] In this embodiment, the use of a filter screen can prevent larger impurities such as larger leaves and pebbles from entering the fan 6, thus providing good protection.

[0036] In summary, compared with related technologies, this solution, consisting of a frame 1, a threshing drum 2, a feed hopper 3, and a discharge port 4, constitutes the main body of a double-drum threshing machine that facilitates collection in the prior art. After improvement, when the threshed corn kernels are discharged from the discharge port 4, the blower 6 can be started. The wind generated by the blower 6 acts on the corn kernels discharged from the discharge port 4 through the blowing mechanism. Since the corn kernels and the small impurities mixed in them have different weights, the lighter small impurities will be blown away from the corn kernels under the action of the wind, thereby achieving the function of removing impurities from the corn kernels and effectively improving the collection quality of corn kernels. Through the use of the conveying mechanism, the corn to be threshed can be fed from a low position to a high position into the feed hopper 3, which can reduce the intensity of manual labor.
