Description
Technical Field
[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a peanut shelling roller device that uses a striking and kneading motion. Background Technology
[0002] Most peanut shelling machines on the market currently use a striking and kneading type. This type of shelling machine mainly consists of a feeding hopper, shelling drum, grid screen, blower, and vibrating screen. The peanut shelling process relies on multiple flat striking rods fixed on the drum to impact and crush the peanut pods, completing the shelling step. The crushed peanut pods pass through the screen, and the cleaning blower blows away the broken outer shells to obtain the kernels, thus separating the peanut kernels from the shells.
[0003] However, existing shelling machines have a flat plate that is tangential to the outer diameter of the drum, meaning the mating surface of the flat plate and the concave screen is perpendicular to the drum diameter. This results in a large clearance between the flat plate and the concave screen, making it impossible to adjust the clearance according to requirements. This leads to problems such as longer shelling times and higher peanut kernel damage rates. The productivity and damage rate of peanut shelling machines differ significantly from the actual needs of peanut production. Furthermore, the shelling radius of existing shelling drums is fixed and cannot be adjusted to suit different shelling machine models, limiting their applicability. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as long shelling time and high peanut kernel damage rate, and to provide a percussion and kneading peanut shelling roller device that can both improve shelling efficiency and reduce peanut kernel damage rate.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A peanut shelling drum device using a striking and kneading motion includes a motor, a drum shaft driven and connected to the motor, a first support plate and a second support plate disposed at both ends of the drum shaft, and at least three sets of striking mechanisms disposed between the first support plate and the second support plate via an adjusting component; the first support plate and the second support plate are both coaxially disposed with the drum shaft.
[0007] The plate-beating mechanism includes a support plate fixedly connected to the adjusting assembly, a scraper fixedly disposed on the support plate, and a plurality of transverse protrusions covering the outer mating surface of the scraper; wherein...
[0008] The top of the transverse ridge away from the scraper is rounded.
[0009] Furthermore, the adjustment assembly includes a docking housing fixedly disposed on the first support plate and / or the second support plate, an adjustment rod fixedly mounted on the support plate, an adjustment elongated hole opened on the docking housing, an adjustment gear shaft installed in the adjustment elongated hole, and an adjustment rack disposed on the side of the adjustment rod;
[0010] The adjustment elongated hole is opened radially along the first support plate and / or the second support plate; the docking housing and the corresponding first support plate or second support plate surround a docking cavity; during installation, the adjustment rod passes through the docking cavity, and the adjustment rack meshes with the corresponding adjustment gear shaft.
[0011] Furthermore, it also includes an opening and closing mechanism for controlling the disengagement / engagement of the adjusting rack and the adjusting gear shaft;
[0012] The opening and closing mechanism includes a groove formed on the inner side of the scraper, a slider slidably disposed in the groove, an opening and closing rod fixedly connected to the slider by screws, and an opening and closing rack disposed on the side of the opening and closing rod.
[0013] Furthermore, during installation, the opening and closing rod passes through the docking cavity, and the opening and closing rack is arranged opposite to the corresponding adjusting gear shaft; the opening and closing rod and the adjusting rod are respectively arranged on both sides of the adjusting elongated hole.
[0014] Furthermore, when it is necessary to adjust the tilt angle of the scraper, slide the slider to disengage the opening and closing rack from the adjusting gear shaft, rotate the adjusting gear shaft, and adjust the position of the support plate in the docking cavity.
[0015] Furthermore, when it is necessary to adjust the working radius of the roller device, the adjusting rack and adjusting gear shaft, and the opening and closing rack and adjusting gear shaft are all in a meshing state. Rotating the adjusting gear shaft drives the support plate and the opening and closing plate to adjust their positions synchronously.
[0016] Furthermore, two adjusting gear shafts are provided in one of the adjusting elongated holes, and both adjusting gear shafts are meshed with the adjusting rack and the opening and closing rack.
[0017] Furthermore, the plate-beating mechanism comprises three sets, which are arranged in a circular array between the first support plate and the second support plate.
[0018] Furthermore, the first support plate and / or the second support plate include a disc portion fixedly mounted to the roller shaft, at least three support portions fixedly disposed on the disc portion, and reinforcing ribs disposed between adjacent support portions.
[0019] The beneficial effects of this invention's percussion and kneading peanut shelling roller device are:
[0020] In this invention, the beating mechanism is connected to the first or second support plate via an adjusting component. This component allows for position adjustment of the scraper within the beating mechanism, thereby adjusting the drum's striking diameter and improving its versatility. Driven by a motor, the drum shaft has several transverse ridges covering the mating surface between the scraper and the screen. These ridges increase friction between the scraper and the screen, squeezing and kneading the peanut pods to break their shells. Compared to a flat beating mechanism, the ridges create uneven force on the peanut pod surface, making them more prone to breakage and shortening the shelling time, significantly improving shelling efficiency. Furthermore, the ridges are positioned away from the top of the scraper, featuring rounded corners. This rounded corner design effectively prevents damage to the peanut kernel skin, solving the problems of low shelling efficiency and high kernel damage rate in existing technologies.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0033] like Figures 1-9 The present invention provides a specific embodiment of a percussion and kneading peanut shelling roller device, comprising a motor, a roller shaft 1 driven by the motor, a first support plate 2 and a second support plate 3 disposed at both ends of the roller shaft 1, and at least three sets of striking mechanisms 5 disposed between the first support plate 2 and the second support plate 3 via an adjusting component 4; the first support plate 2 and the second support plate 3 are both coaxially disposed with the roller shaft 1. The striking mechanism 5 includes a support plate 51 fixedly connected to the adjusting component 4, a scraper 52 fixedly disposed with the support plate 51, and a plurality of transverse protrusions 53 covering the outer mating surface of the scraper 52; wherein the top of the transverse protrusions 53 away from the scraper 52 is rounded. In one embodiment, the scraper 52 is 370 mm long, 40 mm wide, and 8 mm thick; the protrusions of the transverse protrusions 53 have a height undulation of 0.97 mm, and the sides of the transverse protrusions 53 are isosceles triangles with a tooth peak angle of 90° between the undulations. The top of each transverse protrusion 53 is rounded by 0.3 mm to prevent sharp corners from damaging the surface of the peanut kernels.
[0034] like Figure 7 and Figure 8 As shown, in this embodiment, the striking mechanism 5 is connected to the first support plate 2 or the second support plate 3 through an adjusting component 4. The adjusting component 4 can adjust the position of the scraper 52 in the striking mechanism 5, thereby adjusting the striking diameter of the roller and improving the versatility of the roller. The roller shaft 1 is driven by a motor. Several transverse convex strips 53 are provided on the mating surface between the scraper 52 and the screen. The transverse convex strips 53 increase the friction between the scraper 52 and the screen in the shelling machine, squeezing and kneading the peanut pods to break the shells, shortening the shelling time and improving the shelling efficiency.
[0035] Meanwhile, compared to a flat scraper, the transverse convex strip 53 causes uneven force on the peanut pod surface, making it more prone to breakage and shortening the shelling time, thus significantly improving the efficiency of peanut shelling. Furthermore, the transverse convex strip 53 of this invention is located away from the top of the scraper 52 and has a rounded corner design. This rounded corner design effectively prevents damage to the peanut kernel skin, solving the problems of low peanut shelling efficiency and high peanut kernel damage rate in existing technologies.
[0036] The adjustment component 4 in this embodiment includes a docking housing 41 fixedly mounted on the first support plate 2 and / or the second support plate 3, an adjustment rod 42 fixedly mounted on the support plate 51, an adjustment elongated hole 43 opened on the docking housing 41, an adjustment gear shaft 44 installed in the adjustment elongated hole 43, and an adjustment rack 45 disposed on the side of the adjustment rod 42.
[0037] The adjusting elongated hole 43 is opened radially along the first support plate 2 and / or the second support plate 3. The adjusting elongated hole 43 penetrates the first support plate 2 and the second support plate 3, which facilitates the installation and movement of the adjusting gear shaft 44. The docking housing 41 and the corresponding first support plate 2 or second support plate 3 form a docking cavity. During installation, the adjusting rod 42 passes through the docking cavity, and the adjusting rack 45 meshes with the corresponding adjusting gear shaft 44.
[0038] like Figures 4 to 7 As shown, this embodiment also includes an opening and closing mechanism 6 for controlling the disengagement / engagement of the adjusting rack 45 and the adjusting gear shaft 44. The opening and closing mechanism 6 includes a groove 61 formed on the inner side of the scraper 52, a slider 62 slidably disposed in the groove 61, an opening and closing rod 63 fixedly connected to the slider 62 by screws, and an opening and closing rack 64 disposed on the side of the opening and closing rod 63. During installation, the opening and closing rod 63 passes through the docking cavity, and the opening and closing rack 64 is disposed opposite to the corresponding adjusting gear shaft 44; the opening and closing rod 63 and the adjusting rod 42 are respectively disposed on both sides of the adjusting elongated hole 43. As a specific embodiment, two adjusting gear shafts 44 are disposed in one adjusting elongated hole 43, and both adjusting gear shafts 44 are engaged with the adjusting rack 45 and the opening and closing rack 64.
[0039] In use, rotating the adjusting gear shaft 44 simultaneously moves the opening / closing rod 63 and the adjusting rod 42 within the docking cavity, thereby adjusting the vertical position of the opening / closing rod 63 and the adjusting rod 42 relative to the first support plate 2 or the second support plate 3, thus adjusting the working radius of the shelling drum. In one specific embodiment, both the adjusting rod 42 and the opening / closing rod 63 are 90 mm long, 11 mm wide, and 8 mm thick, with an additional 11 mm thickening at the connection point with the scraper 52. The adjusting rack 45 is located in the lower half of the adjusting rod 42 and meshes with the adjusting gear. When the adjusting gear does not mesh synchronously with the adjusting rod 42 and the opening / closing rod 63, rotating the adjusting gear can adjust the tilt angle of the scraper 52 relative to the working circle tangent of the drum.
[0040] Specifically, when it is necessary to adjust the tilt angle of the scraper 52, the sliding slider 62 disengages the opening and closing rack 64 from the adjusting gear shaft 44, and the adjusting gear shaft 44 is rotated to adjust the position of the support plate 51 in the docking cavity. When it is necessary to adjust the working radius of the roller device, the adjusting rack 45 and the adjusting gear shaft 44, and the opening and closing rack 64 and the adjusting gear shaft 44 are all in a meshing state. Rotating the adjusting gear shaft 44 drives the support plate 51 and the opening and closing plate to adjust their positions synchronously.
[0041] like Figure 9 As shown, in this embodiment, the striking mechanism 5 includes three sets, arranged in a circular array between the first support plate 2 and the second support plate 3. Three 8mm wide adjustment holes 43 are evenly distributed on the shaft plate connected to the adjusting rod 42 for vertical adjustment of the adjusting rod 42. Both the first support plate 2 and the second support plate 3 are made of 45# steel, which has high rigidity, ensuring that the shelling roller will not deform during high-intensity shelling operations. In this embodiment, the first support plate 2 and / or the second support plate 3 include a disc portion 21 fixedly mounted to the roller shaft 1, at least three support portions 22 fixedly disposed on the disc portion 21, and reinforcing ribs 23 disposed between adjacent support portions 22. The reinforcing ribs 23 further ensure the strength and load-bearing capacity of the support plate.
[0042] The peanut shelling roller device in this embodiment is as follows: Figure 1 As shown, three scrapers 52 are evenly distributed between the first support plate 2 and the second support plate 3. The scrapers 52 and the support plates are bolted together by an adjustment mechanism, and the scrapers 52 are tilted at an angle according to the size of the peanut pods. Figure 5As shown, the scraper 52 is 370 mm long, 40 mm wide, and 8 mm thick, with a thickness varying by 0.97 mm depending on the surface characteristics. The spacing between the horizontal stripes is 2 mm, and the tops of the stripes have a 0.3 mm rounded corner. During operation, the peanut shelling drum uses the scraper 52 and the screen to shell the peanut pods. As the scraper 52 rotates, it pulls the peanut pods to the part in contact with the screen, where they are squeezed and rubbed to remove the shells. Several transverse ridges 53 on the surface of the scraper 52 increase the friction with the peanut pod surface, preventing the pods from slipping during crushing. Simultaneously, the rounded corners above the transverse ridges 53 prevent damage to the outer skin of the remaining peanut kernels after shelling. This process is repeated until all peanut pods are successfully shelled and fall through the gaps in the screen. Throughout the peanut shelling process, the scraper 52 with transverse convex strips 53 improves the net shelling rate of peanut pods. At the same time, the rounded corner structure at the top of the transverse convex strips 53 effectively reduces damage to the peanut kernel skin, greatly improving the shelling quality of peanut pods.
[0043] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
