Description

TECHNICAL FIELD

[0001] The present application relates to an agricultural mechanical equipment, more particularly to a threshing and cleaning device suitable for irregular grain type beans. BACKGROUND

[0002] In the prior art, the applicant's previous patent number 202210560738.8, named a threshing mechanism, adopts a drum containing structure, after the beans enter the internal space, the beans are threshed by the outer peripheral screen and the inner side threshing assembly, the specific closed threshing assembly is provided with long and short bars, and the space through which the beans pass is formed by the gap between the long and short bars, and the seeds are efficiently threshed during the turning process. The short bar adopts a rotating mechanism to change the relative position state with the screen to avoid damage to the seeds, but the swinging state affects the normal extrusion and threshing of the seeds, and the relative constant spacing state of the long and short bars and the screen limits the application of the threshing mechanism, which cannot adapt to the threshing and cleaning of beans of different specifications, and small beans cannot be normally extruded and threshed by the screen and the threshing assembly, and irregular grain type beans may be damaged by the gap between the screen and the threshing assembly, so it is necessary to design a threshing and cleaning device suitable for more specifications and more irregular grain type beans. SUMMARY

[0003] In view of the deficiencies in the prior art, the purpose of the present application is to provide a threshing and cleaning device suitable for irregular grain type beans, which can adapt to the extrusion and threshing of more specifications and irregular grain type beans, and improve the applicability of the threshing and cleaning device.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a threshing and cleaning device suitable for irregular grain type beans, comprising a rack, a cylindrical screen for carrying materials arranged on the rack, a rotating shaft rotatably arranged in the middle of the rack, and a threshing assembly arranged on the rotating shaft and cooperating with the screen to rotate and thresh, a spiral plate is arranged at the inlet end of the rack for inputting materials into the cylindrical screen, an outlet is arranged at the outlet end of the rack for discharging impurities, the threshing assembly comprises a material guiding cone, a supporting inner cylinder and a threshing piece group, the material guiding cone guides the materials received by the spiral plate, the supporting inner cylinder receives the material guiding cone, the material guiding cone and the supporting inner cylinder are arranged on the rotating shaft to rotate synchronously, the threshing piece group is arranged on the outer circumference of the supporting inner cylinder, and the supporting inner cylinder and the screen form a closed threshing space, and the threshing piece group cooperates with the screen to extrude the materials and thresh in the closed threshing space during rotation;

[0005] The threshing piece group comprises a long bar and a short bar,

[0006] Long grooved rods are arranged in several groups at intervals on the circumference of the inner cylinder. These groups of long grooved rods are arranged with the axial direction of the inner cylinder as a reference, thus covering the entire axial direction of the inner cylinder. The part not covered in the circumferential direction forms the first gap for material passage. Each group of long grooved rods is arranged in several closely arranged sub-modules along the length direction. These sub-modules are reciprocally mounted on a long support and pushed outward by their respective elastic elements, so that the sub-modules maintain the initial distance from the screen. When material passes between the sub-modules and the screen, the large-sized material squeezes the sub-modules to retract and compress the elastic elements, thereby increasing the distance for passage.

[0007] Multiple sets of short grooved rods are set on the circumference of the inner cylinder, and each set has multiple intervals with the axial direction of the inner cylinder as the reference. The intervals form a second gap for material to pass through.

[0008] As an improvement, the elastic elements of adjacent sub-modules are configured to have different elastic forces, so that when large-sized materials squeeze adjacent sub-modules, the force exerted on the materials by the adjacent sub-modules and the screen will be different.

[0009] As an improvement, the elastic forces of the elastic elements in adjacent sub-modules are arranged in an orderly manner with large and small intervals.

[0010] As an improvement, the outer surfaces of several sub-modules that come into contact with the material are inclined toward the material.

[0011] As an improvement, the tilt angles of the outer surfaces of several sub-modules differ.

[0012] As an improvement, the tilt angles of the outer surfaces of adjacent sub-modules are set in an orderly manner with large and small intervals.

[0013] As an improvement, the short grooved rods are reciprocatingly mounted on the short support and pushed outwards by their respective elastic elements, maintaining an initial distance between the short grooved rods and the screen. When material passes between the short grooved rods and the screen, the large material size compresses the short grooved rods, causing them to retract and compress the elastic elements, thereby increasing the distance for passage.

[0014] As an improvement, the short grooved bar is oscillatingly mounted on a short support via a rotating mechanism. The short grooved bar dynamically compresses the material at varying angles by oscillating in conjunction with the screen.

[0015] The beneficial effects of this invention are as follows: Based on the original closed threshing space for kneading and threshing, the specific structure of the long-ribbed rod is optimized. That is, the long-ribbed rod is set as several sub-modules. The distance between the long-ribbed rod and the screen can be flexibly adjusted by the floating of the sub-modules. This allows it to accommodate more specifications and irregularly shaped beans and perform extrusion threshing, thereby improving the applicability of the threshing and cleaning device.

[0022] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] like Figures 1-6 The diagram shows a specific embodiment of the threshing and cleaning device for irregularly shaped beans according to the present invention. It includes a frame 0, a cylindrical screen 1 mounted on the frame 0 for carrying material, a rotating shaft 2 rotatably mounted in the middle of the frame 0, and a threshing assembly 3 mounted on the rotating shaft 2 that cooperates with the screen 1 for threshing. A spiral plate 4 is provided at the inlet end of the frame 0 to allow material to be fed into the cylindrical screen 1, and an outlet is provided at the outlet end of the frame 0 for discharging impurities. The threshing assembly 3 includes a guide... The material guide cone 31, the supporting inner cylinder 32, and the threshing assembly 33 are arranged on the outer circumference of the supporting inner cylinder 32. The material guide cone 31 receives the spiral plate 4 to guide the material, and the supporting inner cylinder 32 receives the material guide cone 31. The material guide cone 31 and the supporting inner cylinder 32 are arranged on the rotating shaft 2 to rotate synchronously. The threshing assembly 33 is arranged at intervals on the outer circumference of the supporting inner cylinder 32. The supporting inner cylinder 32 and the screen 1 form a closed threshing space. When rotating, the threshing assembly 33 cooperates with the screen 1 to squeeze the material in the closed threshing space to thresh it.

[0024] The threshing unit 33 includes long grooved rods 331 and short grooved rods 332. The long grooved rods 331 are arranged in several groups at intervals on the circumference of the inner support cylinder 32. The groups of long grooved rods 331 are arranged with the axial direction of the inner support cylinder 32 as the reference, thereby covering the entire axial direction of the inner support cylinder 32. The part not covered in the circumferential direction forms the first gap 3310 for material passage. Each group of long grooved rods 331 is arranged in several closely arranged sub-modules 5 along the length direction. The sub-modules 5 are reciprocally mounted on the long support 51 and pushed outward by their respective elastic elements 6, so that the sub-modules 5 maintain the initial distance between the screen 1 and the screen. When the material passes between the sub-modules 5 and the screen 1, the large-sized material squeezes the sub-modules 5 to retract and compress the elastic elements 6, thereby increasing the distance for passage. The short grooved rods 332 are arranged in multiple groups on the circumference of the inner support cylinder 32, and each group is arranged in multiple intervals with the axial direction of the inner support cylinder 32 as the reference. The intervals form the second gap 3320 for material passage.

[0025] For a detailed description of the specific implementation of this invention, please refer to the applicant's previous patent, number 202210560738.8, entitled "A Threshing Mechanism". A screen 1 is mounted on the frame 0 to form a cylindrical space for carrying materials. A rotating shaft 2 is rotatably mounted on the frame 0 and coaxial with the cylindrical axis of the screen 1. The material, i.e., the unthreshed beans, is rotated into the cylindrical space from the spiral plate 4 at the inlet end. The guide cone 31 of the threshing assembly 3, together with the spiral plate 4, first guides and conveys the material to the position of the supporting inner cylinder 32. The material is placed at the bottom of the screen 1. Relying on the annular closed threshing space formed by the supporting inner cylinder 32 and the screen 1 (in actual use, because the screen 1 is open above and the material is concentrated in the lower space by gravity, the closed threshing space is only the area covered by the lower screen 1), when the material is pushed orderly towards the outlet end, the threshing component group 33, which is arranged at intervals on the outer circumference of the supporting inner cylinder 32, can achieve the kneading effect of the material in a small space by the threshing component group 33 in conjunction with the screen 1, thereby kneading the bean seeds out of the pods and improving the threshing effect. The seeds that are completely removed from the pods can fall down from the mesh of the screen 1 and continue to be conveyed to the subsequent station; the remaining pods, branches and other impurities are pushed to the outlet end for discharge. In practical implementation, the threshing of whole edible beans can be achieved solely by the threshing component 3 with a closed threshing space (not shown in the attached diagram), or the threshing component 3 with a closed threshing space can be supplemented by an existing open threshing structure with an open threshing space to achieve a comprehensive threshing and cleaning function (such as...). Figure 1 As shown), the front section adopts a closed threshing space, while the rear section adopts an existing open threshing structure. The open space of the open threshing structure can accommodate more impurities and transport them to the outlet, and also assist the three grains in the front threshing components that have not yet been completely threshed to complete the final threshing.

[0026] As an innovation of this invention, the threshing assembly 33, in its specific implementation, relies on the gap between the long grooved rod 331, the short grooved rod 332 and the screen 1 to knead the material. The long grooved rod 331 itself is set as several reciprocating sub-modules 5, and each is floated and limited by its own independent elastic element 6. In the initial position, the several sub-modules 5 maintain a small distance from the screen 1. When threshing and cleaning beans of different sizes or irregular shapes, the sub-modules 5 can collide with each other when they rotate to reach the beans, and the beans push the contacting sub-modules 5 away. In the process of the sub-modules 5 being pushed away while rotating continuously, the beans are fully kneaded by the different sub-modules 5 and the screen 1, achieving a good threshing effect. Several sub-modules 5 in a row can be effectively pushed open by beans, pods, branches, and other impurities, thus ensuring threshing while avoiding compression between materials and impurities, preventing conveying blockages, or damaging the grains. The closely arranged sub-modules 5 along their length prevent materials or impurities from getting stuck in the gaps, and allow different positions to independently contact and compress the materials or impurities, improving the flexibility of material conveying and threshing, as well as impurity transport. Sub-modules 5 that lose pressure from materials or impurities are reset by the elastic force of the elastic element 6, waiting to contact the materials again for compression and threshing. The new long-ribbed rod 331 structure avoids the continuous obstruction of beans or impurities and eliminates the need for discharge holes as in existing technologies, thus avoiding the problem of impurities getting stuck in the discharge holes and making material compression difficult. Meanwhile, by setting up several sets of long grooved rods 331 in the same way as existing technology and leaving a first gap 3310 for material to pass through, the material or impurities will not accumulate. When there is a large amount of material input, it is conveyed backward in an orderly manner and separated and cleaned by the long grooved rods 331 and short grooved rods 332 that cover the entire length of the inner support cylinder 32.

[0027] Preferably, two sets of spaced-apart long threaded rods 331 are used, such as Figure 2 As shown, the material is arranged axially back and forth in the inner cylinder 32, effectively blocking the material in the axial direction. During the entire rotation process, the material is guaranteed to reach the long grooved rod 331 for thorough kneading. The kneaded grains and impurities can continue to be conveyed through the long grooved rod 331. To avoid the material getting stuck at the long grooved rod 331, several sets of short grooved rods 332 are set on the outer circumference of the inner cylinder 32 to comprehensively knead the beans that have not been threshed or have not been completely threshed during the axial conveying process, thereby achieving a good threshing effect. The second gap 3320 left between each set of short grooved rods 332 ensures that the material and impurities in the areas not covered by the short grooved rods 332 can pass smoothly, while the covered areas can produce a threshing effect, making the overall material conveying smoother and taking into account the threshing effect. The multiple sets of short grooved rods 332 on the circumference further improve the threshing efficiency.

[0028] As an improved specific implementation, the elastic element 6 of adjacent sub-modules 5 is configured to have different elastic forces, so that when large-sized materials squeeze adjacent sub-modules 5, the force exerted on the materials by adjacent sub-modules 5 and screen 1 is different.

[0029] In practical implementation, in order to further improve the kneading effect on beans of different sizes and irregular shapes, the elastic element 6 is set to have different elastic forces. When the long grooved rod 331 rotates to the beans, if the volume of the beans can contact the adjacent sub-module 5, the kneading and squeezing state of the beans will vary depending on the degree to which the adjacent sub-module 5 is pushed open. That is, on the one hand, the irregular beans push the sub-module 5 open to different degrees, and on the other hand, the different elastic forces bring different resistance pressures to the beans. This will cause the beans to move irregularly and be kneaded irregularly, thereby achieving a more thorough kneading and threshing effect of the sub-module 5 and the screen 1 on the beans, promoting more efficient separation of the seeds and pods, and ultimately bringing a better threshing effect.

[0030] As an improved specific implementation, the elastic forces of the elastic elements 6 of adjacent sub-modules 5 are arranged in an orderly manner with large and small intervals.

[0031] In practical implementation, the elastic force of the elastic element 6 can be set to two specifications, one large and one small, and then installed at intervals during installation, so as to achieve the difference in elastic force between adjacent elastic elements 6, achieve the technical effect mentioned above, and reduce the types of components, manufacturing costs and assembly difficulty.

[0032] As an improved specific implementation, the outer surfaces of several sub-modules 5 that come into contact with the material are inclined toward the material.

[0033] like Figure 3 , 4 As shown, several sub-modules 5 with their outer surfaces inclined toward the material can first contact the material after rotating and reaching it. Then, during the squeezing and kneading process, the sub-modules 5 are driven to retract, ensuring smooth movement of the sub-modules 5. The material can be smoothly kneaded and granulated throughout the process.

[0034] As an improved specific implementation, the outer surface tilt angles of several sub-modules 5 are different.

[0035] like Figure 3 , 4As shown, in order to further improve the kneading effect on beans of different sizes and irregular shapes, the outer surface of the sub-module 5 is set with different tilt angles. When the long-ribbed rod 331 rotates to the beans, if the volume of the beans can contact the adjacent sub-module 5, the two sub-modules 5 with different tilt angles will promote the beans to make more flexible turning contact and kneading. The step caused by the height difference between the two adjacent sub-modules 5 also makes the kneading and separation of the pods and seeds more thorough.

[0036] As an improved specific implementation, the tilt angles of the outer surfaces of adjacent sub-modules 5 are set in an orderly manner with large and small intervals.

[0037] like Figure 3 , 4 As shown, the tilt angle of the outer surface of adjacent sub-modules 5 can be set to two specifications, one large and one small. Then, they are installed at intervals during installation to achieve the angle difference between adjacent sub-modules 5, thereby achieving the technical effect mentioned above, and reducing the types of components, manufacturing costs and assembly difficulty.

[0038] As an improved specific implementation, the short grooved rod 332 is reciprocally mounted on the short support 71 and pushed outward by its respective elastic element 6, so that the short grooved rod 332 and the screen 1 maintain the initial distance. When the material passes between the short grooved rod 332 and the screen 1, the large material size squeezes the short grooved rod 332 to retract and compress the elastic element 6, thereby increasing the distance for passage.

[0039] like Figure 5 As shown, the submodule 5 of the long grooved rod 331 has the same function. The short grooved rod 332 is limited by the elastic element 6. In the initial position, the short grooved rod 332 maintains a small distance from the screen 1. When threshing and cleaning beans of different sizes or irregular shapes, the short grooved rod 332 can collide with the beans when it rotates to the beans. The beans push the short grooved rod 332 away from the contact. During the continuous rotation and being pushed away, the beans are fully rubbed by the short grooved rod 332 and the screen 1, achieving a good threshing effect. Moreover, it does not require setting a discharge hole as in the prior art, thus avoiding the problem of impurities getting stuck in the discharge hole and the material being squeezed in the prior art.

[0040] As an improved specific implementation, the short grooved rod 332 is oscillatingly mounted on the short bracket 71 via a rotating mechanism 8. The short grooved rod 332, through oscillation, works in conjunction with the screen 1 to dynamically compress the material at varying angles.

[0041] like Figure 6As shown, the specific implementation of the rotating mechanism 8 can be achieved by referring to the applicant's previous patent number 202210560738.8, entitled "A Threshing Mechanism". By setting the rotating mechanism 8, a dynamic squeezing and kneading effect is generated between the short grooved rod 332 and the screen 1 when kneading the beans. On the one hand, the kneading quality is improved, and on the other hand, the structure can be adapted to the kneading and threshing work of different beans without the need to adjust the spacing.

[0042] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
