Description

Technical Field

[0001] The invention relates to agricultural mechanical equipment, and more particularly to a threshing and cleaning device suitable for beans with irregular grains. Background Art

[0002] In the prior art, the applicant's previous patent number is 202210560738.8, and its name is an invention patent for a threshing mechanism, which adopts a drum containing structure. After the beans enter the internal space, the beans are podded through the peripheral screen and the inner threshing assembly. The specific closed threshing assembly is equipped with a long-grained rod and a short-grained rod to cooperate, and the gap between the long-grained rod and the short-grained rod is used to form a space for the beans to pass through, and the grains are efficiently threshed during the flipping process. The short-grained rod adopts a rotating mechanism to change the rotation of the short-grained rod in the specific implementation. The relative position state with the screen avoids damage to the grains, but its swinging state affects the normal extrusion and threshing of the grains, and the relatively unchanged spacing state between the long-grain rod, the short-grain rod and the screen limits the application surface of the threshing mechanism, and it cannot adapt to the threshing and cleaning of beans of different specifications. Small beans cannot be normally squeezed and podded by the screen and the threshing component, and irregular-shaped beans may have difficulty passing through the gap between the screen and the threshing component, causing damage to the beans. Therefore, it is necessary to design a threshing and cleaning device that can be applied to beans of more specifications and more irregular grains. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a threshing and cleaning device suitable for irregular-shaped beans, which can adapt to the extrusion threshing of beans of more specifications and irregular grains, and improve the applicability of the threshing and cleaning device.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a threshing and cleaning device suitable for irregular grain beans, comprising a frame, a cylindrical screen arranged on the frame for carrying materials, a rotating shaft rotatably arranged in the middle of the frame, and a threshing assembly arranged on the rotating shaft for rotating threshing in cooperation with the screen, a spiral plate is arranged at the inlet end of the frame for inputting materials into the cylindrical screen, an outlet is arranged at the outlet end of the frame for discharging impurities, the threshing assembly comprises a material guide cone, a supporting inner cylinder and a threshing component group, the material guide cone receives the spiral plate to guide the materials, the supporting inner cylinder receives the material guide cone, the material guide cone and the supporting inner cylinder are arranged on the rotating shaft for synchronous rotation, the threshing component group is arranged at intervals on the outer circumference of the supporting inner cylinder, the supporting inner cylinder and the screen form a closed threshing space, and the threshing component group cooperates with the screen to squeeze the materials in the closed threshing space for threshing when rotating;

[0005] The threshing unit group includes a long-grain rod and a short-grain rod.

[0006] The long-grained rods are arranged in a plurality of spaced groups on the circumference of the supporting inner cylinder. The plurality of groups of long-grained rods are arranged based on the axial direction of the supporting inner cylinder, thereby covering the entire axial direction of the supporting inner cylinder, and the uncovered part in the circumferential direction forms a first gap for the material to pass through; each group of long-grained rods is arranged in a plurality of closely arranged sub-modules along the length direction, and the plurality of sub-modules are reciprocatingly arranged on the long bracket and pushed outward through their respective elastic members, so that the sub-modules and the screen maintain an initial spacing, and when the material passes between the plurality of sub-modules and the screen, the large-sized material is squeezed to cause the sub-module to retract and compress the elastic member, thereby increasing the spacing for the material to pass through;

[0007] The short-threaded rods are arranged in multiple groups on the circumference of the supporting inner cylinder, and each group is provided with multiple intervals based on the axial direction of the supporting inner cylinder, and the interval positions form a second gap for the material to pass through.

[0008] As an improvement, the elastic members of adjacent submodules are configured to have different elastic forces, so that when large-sized materials squeeze adjacent submodules, the forces exerted by the adjacent submodules and the screen on the materials are different.

[0009] As an improvement, the elastic forces of the elastic members of adjacent submodules are arranged in order with a large and a small interval.

[0010] As an improvement, outer surfaces of several submodules in contact with the material are arranged to be inclined toward the material.

[0011] As an improvement, the outer surfaces of several submodules have different inclination angles.

[0012] As an improvement, the inclination angles of the outer surfaces of adjacent submodules are arranged in order with a large and a small interval.

[0013] As an improvement, the short grooved rods can be reciprocated and set on the short bracket and pushed outward by their respective elastic parts, so that the short grooved rods and the screen maintain an initial distance. When the material passes between the short grooved rods and the screen, the large-sized material is squeezed to cause the short grooved rods to retract and compress the elastic parts, thereby increasing the distance for passing.

[0014] As an improvement, the short-grained rod is swingably mounted on the short bracket through a rotating mechanism, and the short-grained rod cooperates with the screen to dynamically extrude the material at a varying angle through swinging.

[0015] The beneficial effects of the present invention are as follows: on the basis of kneading threshing in the original closed threshing space, the specific structure of the long-grained rod is optimized, that is, the long-grained rod is arranged into a plurality of sub-modules, and the distance with the screen is flexibly adjusted through the floating of the sub-modules, so that beans of more specifications and irregular grains can be adapted to pass through and squeeze threshing can be performed, thereby improving the applicability of the threshing and cleaning device.

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

[0023] like Figure 1-6 As shown in the figure, it is a specific embodiment of the threshing and cleaning device for irregular grain beans of the present invention, which includes a frame 0, a cylindrical screen 1 arranged on the frame 0 for carrying materials, a rotating shaft 2 rotatably arranged in the middle of the frame 0, and a threshing assembly 3 arranged on the rotating shaft 2 for rotating threshing with the screen 1. The inlet end of the frame 0 is provided with a spiral plate 4 for inputting materials into the cylindrical screen 1, and the outlet end of the frame 0 is provided with an outlet for discharging impurities. The threshing assembly 3 includes a guide The material cone 31, the supporting inner cylinder 32 and the threshing component group 33, the material guide cone 31 receives the spiral plate 4 to guide the material, 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 component group 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, and the threshing component group 33 cooperates with the screen 1 to squeeze the material in the closed threshing space for threshing when rotating;

[0024] The threshing component group 33 includes long-grained rods 331 and short-grained rods 332. The long-grained rods 331 are arranged in a plurality of groups at intervals on the circumference of the supporting inner cylinder 32. The plurality of groups of long-grained rods 331 are arranged based on the axial direction of the supporting inner cylinder 32, thereby covering the entire axial direction of the supporting inner cylinder 32, and the uncovered part in the circumferential direction forms a first gap 3310 for the passage of materials; each group of long-grained rods 331 is arranged in a plurality of closely arranged submodules 5 along the length direction, and the plurality of submodules 5 are reciprocatingly arranged on the long bracket 51 and are pushed outward by their respective elastic members 6, so that the submodules 5 and the screen 1 maintain an initial spacing, and when the material passes between the plurality of submodules 5 and the screen 1, the large-sized material squeezes the submodules 5 to retract and compress the elastic members 6, thereby increasing the spacing for the material to pass through; the short-grained rods 332 are arranged in a plurality of groups on the circumference of the supporting inner cylinder 32, and each group is arranged in a plurality of groups at intervals based on the axial direction of the supporting inner cylinder 32, and the interval positions form a second gap 3320 for the passage of materials.

[0025] The specific implementation of the present invention when in use can refer to the applicant's previous patent number 202210560738.8, which is an invention patent for a threshing mechanism. A screen 1 is set on the frame 0 to form a cylindrical space for carrying materials. The rotating shaft 2 can be rotatably set on the frame 0 and is coaxial with the axis of the cylindrical screen 1. The material, that is, 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 cooperates with the spiral plate 4 to first guide and transport the material to the position of the supporting inner cylinder 32, and the material is placed at the bottom of the screen 1, relying on a circle of annular closed threshing space formed by the supporting inner cylinder 32 and the screen 1 (in actual use, because the top of the screen 1 is open, and the material is concentrated in the space below by gravity, the closed threshing space is only the position covered by the lower screen 1). When the material is pushed to the outlet end in an orderly manner, the threshing component group 33 arranged at intervals on the outer circumference of the supporting inner cylinder 32 can cooperate with the screen 1 to rub the material in a small space, thereby rubbing the bean grains out of the bean pods, improving the threshing effect, and the grains completely out of the bean pods can fall downward from the mesh of the screen 1 and continue to be transported to the subsequent workstations; the remaining impurities such as pods, branches and trunks are continued to be pushed to the outlet end for discharge. In the specific implementation, the threshing of the whole edible beans can be realized by the above-mentioned threshing component 3 with a closed threshing space alone (not shown in the drawings), or the threshing component 3 with a closed threshing space can be used to assist the existing open threshing structure with an open threshing space to realize a comprehensive threshing and cleaning function (such as Figure 1 As shown), the front section adopts a closed threshing space, and 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 assist the front section threshing component 3 to complete the final threshing of the grains that have not been completely shredded.

[0026] As an innovation of the present invention, the threshing component group 33, when implemented, relies on the gap between the long-grained rod 331, the short-grained rod 332 and the screen 1 to rub the material. The long-grained rod 331 itself is configured as a plurality of reciprocating submodules 5, and is float-limited by respective independent elastic members 6. In the initial position, the plurality of submodules 5 maintain a small distance from the screen 1. When threshing and selecting beans of different sizes or irregular grain shapes, the submodules 5 can collide with each other when they rotate to reach the beans, and the beans push open the submodules 5 that they contact. In the process of the submodule 5 being pushed open while continuously rotating, the beans are fully rubbed by the different submodules 5 and the screen 1, thereby achieving a good threshing effect. Several submodules 5 in a row can be effectively pushed open by beans, pods, branches and other impurities, so as to ensure rubbing and threshing while avoiding the squeezing between materials and impurities, causing transportation jams, or damaging grains; using several submodules 5 arranged closely in the length direction can avoid the problem of materials or impurities getting stuck in the gap, and different positions can independently contact and squeeze with the contacted materials or impurities, improving the flexibility of material conveying and threshing and impurity conveying. The submodule 5 that loses the squeezing of materials or impurities is reset by the elastic force of the elastic member 6, and then contacts the materials again for squeezing, rubbing and threshing. The new long-grained rod 331 structure avoids the situation where beans or impurities are continuously blocked, and there is no need to set a discharge hole as in the prior art, thereby avoiding the problem that the discharge hole in the prior art will get stuck with impurities and is difficult to clean and squeeze the material. At the same time, by setting up several groups of long groove rods 331 and leaving a first gap 3310 for material to pass through in the same way as the prior art, materials or impurities will not accumulate, and when a large amount of material is input, it will be transported backward in an orderly manner, and separated and cleaned by relying on the long groove rods 331 and short groove rods 332 covering the entire length of the supporting inner cylinder 32.

[0027] As a preference, firstly, two groups of spaced-apart long-grained rods 331 are used, such as Figure 2 As shown, they are arranged front and back in the axial direction of the supporting inner cylinder 32, which fully blocks the material in the axial direction. During the entire rotation process, the material can reach the long-grained rod 331, so as to be fully kneaded. The kneaded grains and impurities can continue to be transported through the long-grained rod 331. In order to avoid the obstruction and jamming of the material at the long-grained rod 331, a plurality of groups of short-grained rods 332 are arranged on the outer circumference of the supporting inner cylinder 32, and the beans that have not been threshed or have not been completely threshed are comprehensively kneaded during the axial transportation process, thereby achieving a good threshing effect. The second gap 3320 left between each group of short-grained rods 332 ensures that the material and impurities at the positions not covered by the short-grained rods 332 can pass smoothly, while the covered positions can produce a threshing effect, so that the overall material transportation is smoother and the threshing effect is taken into account. The setting of multiple groups of short-grained rods 332 on the circumference also further improves the threshing efficiency.

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

[0029] In the specific implementation, in order to further improve the kneading effect of beans of different sizes and irregular grains, the elastic member 6 is set to have different elastic forces. Then, when the long-grained rod 331 rotates to reach the beans, if the volume of the beans can contact the adjacent sub-modules 5, the kneading and squeezing state of the beans will be different due to the different degrees to which the adjacent sub-modules 5 are pushed open. That is, on the one hand, the irregular grains of beans push the sub-modules 5 open to different degrees, and on the other hand, the different elastic forces bring different resistance pressures on the beans, which will drive the beans to perform irregular movements and irregular force kneading, thereby achieving a more sufficient kneading and threshing effect on the beans by the sub-modules 5 and the screen 1, promoting a more efficient separation of the grains and pods, and ultimately bringing a better threshing effect.

[0030] As an improved specific implementation manner, the elastic forces of the elastic members 6 of adjacent submodules 5 are arranged in order with a large and a small interval.

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

[0032] As an improved specific implementation manner, the outer surfaces of the plurality of submodules 5 that are in contact with the material are arranged to be inclined toward the material.

[0033] like Figure 3 , 4 As shown, several sub-modules 5 with outer surfaces inclined toward the direction of the material can first contact the material with the outer surface after rotating to reach the material, and then drive the sub-modules 5 to retract during squeezing and kneading, thereby ensuring smooth movement of the sub-modules 5 and the material can be smoothly kneaded and threshed during the whole process.

[0034] As an improved specific implementation manner, the outer surface inclination angles of several submodules 5 are different.

[0035] like Figure 3 , 4As shown, in order to further improve the kneading effect of beans of different sizes and irregular grain shapes, the outer surface of the submodule 5 is set to have different inclination angles. When the long-grained rod 331 rotates to reach the beans, if the volume of the beans can contact the adjacent submodule 5, the two submodules 5 with different inclination angles will promote the beans to be more flexibly turned over, contacted and kneaded. The steps caused by the height difference between the two adjacent submodules 5 also make the kneading and separation of the pods and grains more complete.

[0036] As an improved specific implementation manner, the inclination angles of the outer surfaces of adjacent submodules 5 are arranged in order with a large and a small interval.

[0037] like Figure 3 , 4 As shown, the inclination angles of the outer surfaces of adjacent submodules 5 can be set to two specifications, one large and one small, and then installed at intervals during installation, so as to achieve the angle difference between adjacent submodules 5, achieve the technical effects mentioned above, and reduce the types of components, manufacturing costs and assembly difficulty.

[0038] As an improved specific implementation method, the short groove rod 332 is reciprocatably arranged on the short bracket 71 and is pushed outward by the respective elastic members 6, so that the short groove rod 332 and the screen 1 maintain an initial distance. When the material passes between the short groove rod 332 and the screen 1, the large-sized material is squeezed to cause the short groove rod 332 to retract and compress the elastic member 6, thereby increasing the distance for passing.

[0039] like Figure 5 As shown, the submodule 5 has the same function as the long-grained rod 331, and the short-grained rod 332 is limited by the elastic member 6. In the initial position, the short-grained rod 332 maintains a small distance from the screen 1. When threshing and cleaning beans of different sizes or irregular grains, the short-grained rod 332 can interfere with each other when it rotates to reach the beans, and the beans push the short-grained rod 332 that it contacts away. In the process of the short-grained rod 332 being pushed away while rotating continuously, the beans are fully kneaded by the short-grained rod 332 and the screen 1, thereby achieving a good threshing effect, and there is no need to set a discharge hole as in the prior art, thereby avoiding the problem in the prior art that impurities are stuck in the discharge hole and it is difficult to clean and squeeze the material.

[0040] As an improved specific implementation manner, the short groove rod 332 is swingably mounted on the short bracket 71 via a rotating mechanism 8, and the short groove rod 332 cooperates with the screen 1 to dynamically extrude the material at a varying angle by swinging.

[0041] like Figure 6As shown, the implementation of the specific rotating mechanism 8 can be realized by referring to the applicant's previous patent number 202210560738.8, which is named an invention patent for a threshing mechanism. By setting the rotating mechanism 8, the short grain rods 332 and the screen 1 produce a dynamic extrusion and kneading effect when kneading the beans. On the one hand, the kneading quality is improved, and on the other hand, the structure can also be used to adapt to the kneading and threshing work of different beans without the need to adjust the spacing.

[0042] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
