Abstract
Description
Technical Field
[0001] This utility model relates to the field of harvester technology, and in particular to a high-efficiency integrated machine for harvesting and threshing beans. Background Technology
[0002] A bean harvesting and lifting device is a component of an agricultural harvester used for harvesting beans. It mainly completes the harvesting, crushing, threshing, and collection of beans into a storage bin in one go.
[0003] Traditional bean harvesting and threshing machines typically consist of a frame, wheels, a threshing device, a cutting blade, a single-drum threshing device, a simple screen, and a collection box. The working principle is as follows: the machine moves via the wheels, the threshing device gathers the bean plants together, the cutting blade cuts the stems, and the beans are transported to the single-drum threshing device. The rigid teeth on the drum impact the bean plants to thresh them. The threshed mixture is initially filtered through the simple screen, the grains fall into the collection box, and the impurities are discharged.
[0004] However, traditional equipment has poor operational continuity. Harvesting, threshing, and screening require manual material transfer, which is time-consuming and labor-intensive. Multiple transfers can easily lead to grain loss. Furthermore, the threshing effect is poor. Traditional threshing equipment mostly uses single-drum rigid threshing, which either results in a low threshing rate (more residual grains) due to insufficient force or grain damage due to excessive rigid contact. Secondly, the screening efficiency is low. Simple screening or manual winnowing is used to separate impurities, which is difficult to effectively remove stalk debris, fine soil, etc., resulting in poor grain purity.
[0005] Therefore, a high-efficiency integrated machine for harvesting and threshing soybeans is provided to solve the problems mentioned in the background art. Utility Model Content
[0006] To overcome the above shortcomings, this utility model provides a high-efficiency integrated machine for harvesting and threshing beans, aiming to improve the problems of poor continuity, low threshing rate, high seed breakage rate and poor screening effect in the existing technology.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency integrated bean harvester and threshing machine, comprising a frame, a track fixedly connected to the lower side of the frame, a connecting frame fixedly installed on the left side of the frame, a harvesting component disposed inside the connecting frame, a conveying device fixedly installed on the rear side of the connecting frame, a housing inside the frame, the right side of the conveying device connected to the housing, a front roller fixedly installed inside the housing, a rear roller installed on the right side of the front roller, rigid feeding teeth fixedly connected to the outer side of the front roller, elastic feeding teeth fixedly connected to the outer side of the rear roller, and a screening component disposed on the right side of the rear roller.
[0008] Furthermore, the harvesting assembly includes a reel, which is rotatably connected inside the connecting frame. A pulling component is fixedly connected to the reel, and a hinge is fixedly installed on the rear side of the reel.
[0009] Furthermore, the screening component includes a frame disposed inside the housing. A coarse screen and a fine screen are installed inside the frame. A spring is fixedly connected to the right side of the frame, and the side of the spring away from the frame is fixedly connected to the inner wall of the frame. A motor is fixedly installed on the front side of the housing. A rotating shaft is fixedly connected to the output end of the motor, and an eccentric wheel is fixedly connected to the outer side of the rotating shaft.
[0010] Furthermore, a fan is fixedly installed on the upper side of the housing, and a collection box is fixedly installed on the right side of the fan, with the collection box communicating with the housing.
[0011] Furthermore, the eccentric wheel is rotatably connected to the right side of the frame.
[0012] Furthermore, the coarse screen is positioned directly above the fine screen.
[0013] Furthermore, an inclined plate is installed on the lower side of the front roller.
[0014] Furthermore, an operating platform is fixedly installed on the upper side of the frame.
[0015] This utility model has the following beneficial effects:
[0016] In this invention, the rigid feeding teeth of the front roller perform initial threshing, using high-speed impact and tearing to separate most of the pods from the stems. Then, the elastic feeding teeth of the rear roller gently contact the pods to achieve secondary threshing, avoiding the problem of uneven force when threshing with a single roller. This ensures thorough threshing, reduces damage to the grains caused by excessive impact, and improves the overall quality of the threshing process.
[0017] In this invention, the frame vibrates under the action of an eccentric wheel and a spring, which, together with the graded filtration of coarse and fine screens and the blower to remove light impurities, forms a multi-level impurity separation mechanism. This solves the limitation of traditional screening that can only remove large impurities, effectively separates impurities of different particle sizes, and significantly improves the purity of the final collected grains.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figures 1-2 This utility model provides an embodiment of a high-efficiency bean harvesting and threshing integrated machine, including a frame 1, a track 2 fixedly connected to the lower side of the frame 1, a connecting frame 6 fixedly installed on the left side of the frame 1, an operating platform 3 fixedly installed on the upper side of the frame 1, a harvesting component 4 inside the connecting frame 6, the harvesting component 4 including a pulling reel 41, the pulling reel 41 being rotatably connected to the inside of the connecting frame 6, a pulling component 42 fixedly connected to the pulling reel 41, a hinge 43 fixedly installed on the rear side of the pulling reel 41, a conveying device 5 fixedly installed on the rear side of the connecting frame 6, a housing 16 inside the frame 1, the right side of the conveying device 5 being connected to the housing 16, a front roller 7 fixedly installed inside the housing 16, an inclined plate 17 installed on the lower side of the front roller 7, a rear roller 8 installed on the right side of the front roller 7, rigid feeding teeth 9 fixedly connected to the outer side of the front roller 7, elastic feeding teeth 10 fixedly connected to the outer side of the rear roller 8, and a screening component 11 provided on the right side of the rear roller 8;
[0026] Specifically, the track 2 on the underside of the frame 1 contacts the ground, and the rotation of the track 2 enables the machine to move smoothly in the field. The operator sets the operating parameters and controls the start and stop of the whole machine through the control panel 3 on the frame 1. During operation, the reel 41 on the left side of the connecting frame 6 rotates, and its reeling parts 42 move synchronously with the reel 41, lifting and gathering the scattered and tilted bean plants in the field to the cutting area. After being cut, the bean plants are spirally pushed by the hinge 43 to the conveying device 5 on the rear side of the connecting frame 6. The conveying device 5 continuously feeds the bean plants into the housing 16, realizing a continuous operation from grabbing and cutting the bean plants in the field to orderly conveying them, which is conducive to subsequent threshing. Providing a stable source of material, the bean stalks entering the shell 16 first come into contact with the front roller 7. The front roller 7 rotates at high speed, and its outer rigid feeding teeth 9 move synchronously with the roller, impacting and tearing the bean stalks, causing most of the pods to separate from the stems, thus achieving preliminary threshing. The material after preliminary threshing falls onto the inclined plate 17 on the lower side of the front roller 7 under its own gravity, and slides along the inclined plate 17 to the rear roller 8. When the rear roller 8 rotates, its outer elastic feeding teeth 10 come into contact with the remaining unthreshed pods, and gently separate the residual seeds through elastic force, completing secondary threshing. This achieves graded threshing of the bean stalks, improving threshing efficiency and threshing rate.
[0027] Reference Figures 3-4 The screening component 11 includes a frame 111, which is located inside the housing 16. A coarse screen 112 and a fine screen 113 are installed inside the frame 111. The coarse screen 112 is located directly above the fine screen 113. A spring 115 is fixedly connected to the right side of the frame 111. The side of the spring 115 away from the frame 111 is fixedly connected to the inner wall of the frame 111. A motor 114 is fixedly installed on the front side of the housing 16. A rotating shaft 117 is fixedly connected to the output end of the motor 114. An eccentric wheel 116 is fixedly connected to the outer side of the rotating shaft 117. A fan 14 is fixedly installed on the upper side of the housing 16. A collection box 15 is fixedly installed on the right side of the fan 14. The collection box 15 is connected to the housing 16. The eccentric wheel 116 is rotatably connected to the right side of the frame 111.
[0028] Specifically, the threshed mixture, containing seeds, stalk fragments, and pod shells, enters frame 111. Motor 114 drives shaft 117 to rotate, which in turn drives eccentric wheel 116 to rotate synchronously. The eccentric structure of eccentric wheel 116 causes frame 111 to vibrate at high frequency under the elastic support of spring 115. The coarse screen 112 inside frame 111 vibrates with the frame, filtering and separating larger stalk fragments and pod shells. The fine screen 113 separates the seeds from smaller impurities. Simultaneously, fan 14 is activated, and the airflow generated by fan 14 blows away lighter impurities in the mixture. Finally, the pure seeds fall into collection box 15 for collection. This achieves efficient separation of seeds and impurities, improving the purity of the seeds.
[0029] Working principle: When using this device, the machine moves smoothly in the field via the track 2. The operator controls the operation of the whole machine through the control panel 3 on the frame 1. During operation, when the reel 41 rotates, its reeling parts 42 lift and gather the bean plants. After being cut, the reel 43 conveys the bean plants to the conveying device 5 on the rear side of the connecting frame 6. The conveying device 5 sends the bean plants into the shell 16. The bean plants entering the shell 16 are first processed by the front roller 7. The rigid feeding teeth 9 on the outer side of the front roller 7 impact and tear at high speed to achieve preliminary threshing. The material is guided to the rear roller 8 by the inclined plate 17 on the lower side of the front roller 7. The elastic feeding teeth 10 on the outer side of the rear roller 8 make gentle contact for secondary threshing.
[0030] The threshed mixture enters the frame 111. The motor 114 drives the rotating shaft 117 to rotate the eccentric wheel 116, causing the frame 111 to vibrate under the action of the spring 115. The coarse screen 112 in the frame 111 filters out large impurities, and the fine screen 113 separates the grains from the small impurities. At the same time, the blower 14 is started to blow away the light impurities. Finally, the pure grains enter the collection box 15 to complete the collection.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
