Description
Technical Field
[0001] This application relates to the field of raw material screening equipment technology, and in particular to a rapeseed sorting machine. Background Technology
[0002] Rapeseed, also known as rapeseed, is the seed of the cruciferous crop rapeseed. Rapeseed produces relatively long pods, yielding many plump seeds. Rapeseed is one of China's major oilseed and honey-producing crops, and its seeds are a primary raw material for oil extraction.
[0003] Before entering the oil extraction device, rapeseed needs to be carefully selected and impurities removed to improve the quality of the oil. A related technology proposes a selection device, including a frame housing and a blower. The frame housing has a feed inlet at the top and a discharge outlet at the bottom; an air inlet is located on one side of the middle of the frame housing, and an air outlet is located on the other side. The blower is connected to the air inlet. The rapeseed enters the frame housing through the feed inlet and falls under gravity, with the blower removing dust from the rapeseed.
[0004] Regarding the aforementioned technologies, although the blower can remove dust mixed in with rapeseed to a certain extent, the removal effect is not ideal because the rapeseed is in a state of accumulation during its fall. Utility Model Content
[0005] To address the issue of unsatisfactory impurity removal due to the rapeseed accumulating during its fall, this application provides a rapeseed sorting machine.
[0006] The rapeseed beating machine provided in this application adopts the following technical solution:
[0007] A rapeseed sorting machine includes a casing, a sieve cylinder, a first rotating rod, fan blades, and a first drive assembly. The casing has a feed inlet at the top and a discharge outlet at the bottom. The sieve cylinder is horizontally positioned within the casing, with a feed notch on its circumferential wall. The circumferential wall of the sieve cylinder divides the inner cavity of the casing into upper and lower layers, and first sieve holes are evenly distributed on its circumferential wall. A support is mounted on the casing, and the first rotating rod is rotatably connected to the support. The first rotating rod passes through the sieve cylinder along its axis and has stirring blades. The fan blades are located at the end of the first rotating rod that extends out of the sieve cylinder. A dust removal hole communicating with the inner cavity of the sieve cylinder is located on the bottom wall of the sieve cylinder near the fan blades. The first drive assembly is mounted on the support and is used to drive the first rotating rod to rotate.
[0008] By adopting the above technical solution, when rapeseed enters the machine casing through the feed inlet, it first falls into the screen cylinder. The first drive assembly drives the first rotating rod to rotate, causing the stirring blades mounted on the first rotating rod to rotate accordingly, thereby uniformly stirring the rapeseed inside the screen cylinder. Simultaneously, the fan blades at the other end of the first rotating rod rotate with it, generating airflow, which helps to blow out light impurities from the screen cylinder and discharge them through the dust removal holes. After stirring and air separation, qualified rapeseed passes through the first screen holes on the screen cylinder's peripheral wall, falls into the lower space, and is finally discharged from the outlet. Throughout the process, the screen cylinder not only serves a screening function but also facilitates the introduction of materials through the feed opening, ensuring a highly efficient and stable screening and impurity removal effect.
[0009] Optionally, the screen cylinder is rotatably connected to the housing around its own axis, and the bracket is provided with a second drive assembly for driving the screen cylinder to reciprocate around its own axis.
[0010] By adopting the above technical solution, the sieve cylinder is rotatably connected to the machine casing around its own axis, and is driven by the second drive component to reciprocate around its own axis, which can effectively improve the screening efficiency and quality of rapeseed. Specifically, the reciprocating oscillation of the sieve cylinder makes the movement of rapeseed within the sieve cylinder more uniform, which helps to reduce clogging and increases the opportunity for rapeseed to contact the first sieve hole, thereby improving screening accuracy. In addition, this design can also enhance the air separation effect, further remove impurities, and improve the purity of the final product.
[0011] Optionally, the second drive assembly includes a rotary motor, a second rotating rod, a first connecting rod, and a second connecting rod. The second rotating rod is rotatably connected to the bracket in a transverse direction and is parallel to the first rotating rod. The rotary motor is mounted on the bracket, and the rotating shaft of the rotary motor is connected to the second rotating rod. One end of the first connecting rod is fixedly connected to the second rotating rod, and the other end of the first connecting rod is rotatably connected to the second connecting rod. The other end of the second connecting rod is rotatably connected to the bottom wall of the screen cylinder.
[0012] By adopting the above technical solution, after the rotating motor starts, it drives the second rotating rod to rotate. The rotation of the second rotating rod causes the first connecting rod, which is fixedly connected to it, to rotate as well. The other end of the first connecting rod is rotatably connected to the second connecting rod, thereby pushing the second connecting rod to reciprocate in the vertical direction. Since the other end of the second connecting rod is rotatably connected to the bottom wall of the sieve cylinder, this reciprocating motion is converted into the oscillation of the sieve cylinder around its own axis. This design can not only effectively increase the tumbling frequency of rapeseed in the sieve cylinder, but also enhance the screening efficiency and uniformity, ensuring that the rapeseed is fully separated and screened.
[0013] Optionally, the first drive assembly includes a first gear and a second gear, the first gear being coaxially connected to a second rotating rod, the second gear being coaxially connected to a first rotating rod, and the first gear and the second gear meshing.
[0014] By adopting the above technical solution, the meshing transmission of the first and second gears enables the first rotating rod to rotate synchronously with the rotation of the second rotating rod. This not only simplifies the drive structure and reduces the number of mechanical parts, improving the overall reliability of the equipment, but also ensures the effective operation of the stirring blades inside the sieve cylinder, enhancing the screening efficiency and quality of rapeseed. Simultaneously, this gear transmission method can effectively transmit large torques, ensuring stable operation of the equipment under high loads.
[0015] Optionally, a sliding groove is provided on the side wall of the housing below the screen cylinder, the sliding groove is set at an angle to the horizontal direction, and a second screen plate is slidably inserted in the sliding groove; a first outlet is provided on the side wall of the housing near the lower end of the second screen plate, and a baffle is provided on the first outlet; a third drive assembly for driving the second screen plate to reciprocate is provided on the bracket.
[0016] By adopting the above technical solution, the sliding groove on the side wall of the casing is set at an angle to the horizontal direction, allowing the second screen plate to be placed at an incline under gravity, which is beneficial for the smooth discharge of impurities or unqualified materials during the screening process. A baffle is provided on the first outlet to control the discharge of materials when necessary and avoid unnecessary losses. The third drive component on the support can drive the second screen plate to reciprocate, further enhancing the screening effect and ensuring that impurities are effectively separated and discharged.
[0017] Optionally, the third drive assembly includes a third rotating rod, a cam, a protrusion, and a power component. An elastic element is provided within the slide groove; one end of the elastic element is connected to the second screen plate, and the other end is connected to the inner wall of the slide groove. The elastic element has a tendency to disengage the second screen plate from the slide groove. The third rotating rod is rotatably connected to the bracket about a vertical axis. The cam is located at the bottom of the third rotating rod, and the protrusion is located at one end of the second screen plate extending through the slide groove, abutting against the peripheral wall of the cam. The power component is used to drive the third rotating rod to rotate.
[0018] By adopting the above technical solution, when the power component drives the third rotating rod to rotate, the cam rotates accordingly and periodically pushes the protrusion, thereby driving the second screen plate to reciprocate within the chute. Due to the action of the elastic element, the second screen plate can quickly rebound after being freed from the force of the cam, thus achieving a highly efficient screening effect. This design not only improves the screening efficiency of materials but also effectively avoids clogging.
[0019] Optionally, the power component includes a driving bevel gear and a driven bevel gear, the driving bevel gear being coaxially connected to a first rotating rod, and the driven bevel gear being coaxially connected to a third rotating rod, wherein the driving bevel gear and the driven bevel gear mesh.
[0020] By adopting the above technical solution, the arrangement of the driving and driven bevel gears ensures that the rotation of the first rotating rod is effectively transmitted to the third rotating rod, thereby driving the second screen plate to reciprocate. This improves screening efficiency and accuracy, reduces the power source, and saves costs. The bevel gear structure is compact, and the transmission is smooth and reliable, reducing vibration and noise during equipment operation and extending the equipment's service life.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. The design of the stirring blades and fan blades on the first rotating rod enables uniform stirring and blowing of rapeseed, effectively removing large particles of impurities and dust, significantly improving the quality of rapeseed after screening, and improving the problem that rapeseed is in a state of accumulation when falling, resulting in an unsatisfactory impurity removal effect;
[0023] 2. The design of the screen cylinder reciprocating around its own axis enhances the diversity of material movement trajectories within the screen cylinder, allowing rapeseed of different particle sizes to be more fully dispersed, thus improving screening accuracy and efficiency.
[0024] 3. The combined use of the second screen plate and the third drive assembly enables the second screen plate to move back and forth within the chute, further refining the screening process, enhancing the screening effect, and ensuring that impurities are effectively separated and discharged.

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0030] This application discloses a rapeseed refining machine. (Refer to...) Figure 1-2 The rapeseed beneficiation machine includes a casing 1, a sieve cylinder 2, a first rotating rod 3, a fan blade 4, and a first drive assembly 5. The casing 1 has a feed inlet 11 at the top, a cover plate 12 on the feed inlet 11, a discharge outlet 13 at the bottom, and a bracket 6 welded and fixed to the outer wall of the casing 1.
[0031] Reference Figure 1 The screen cylinder 2 is a cylindrical shape sealed at both ends. It is rotatably connected to the machine housing 1. An inlet 21 is provided on the circumferential wall of the screen cylinder 2, which divides the inner cavity of the machine housing 1 into upper and lower layers. First screen holes 22 are evenly distributed on the circumferential wall of the screen cylinder 2. A second drive assembly 7 is provided on the support 6 to drive the screen cylinder 2 to reciprocate around its own axis. The second drive assembly 7 drives the screen cylinder 2 to reciprocate around its own axis, effectively improving the screening efficiency and quality of rapeseed.
[0032] Reference Figure 2 The first rotating rod 3 is rotatably connected to the support 6 and passes through the screen cylinder 2 along its axis. The portion of the first rotating rod 3 inside the screen cylinder 2 is equipped with stirring blades 31. A first drive assembly 5 is mounted on the support 6 and drives the first rotating rod 3 to rotate. A fan blade 4 is located at the end of the first rotating rod 3 that extends out of the screen cylinder 2. A dust removal hole 23, communicating with the inner cavity of the screen cylinder 2, is opened on the bottom wall of the screen cylinder 2 near the fan blade 4. When the first rotating rod 3 rotates, the fan blade 4 generates airflow, discharging dust and fine impurities from the dust removal hole 23, thereby purifying the material. The stirring blades 31, when the first rotating rod 3 rotates, cause the material inside the screen cylinder 2 to tumble, allowing the release of any light impurities more fully and further improving screening efficiency.
[0033] During operation, rapeseed enters the casing 1 through the feed inlet 11 and falls into the sieve cylinder 2. The first drive assembly 5 drives the first rotating rod 3 to rotate, causing the stirring blades 31 mounted on the first rotating rod 3 to rotate accordingly. This uniformly stirs the rapeseed in the sieve cylinder 2, releasing dust and fine impurities mixed in with the rapeseed. The fan blades 4 at the other end of the first rotating rod 3 rotate together with the first rotating rod 3, generating airflow that blows light impurities out of the sieve cylinder 2 and out through the dust removal holes 23, thereby improving the impurity removal effect of the rapeseed. At the same time, the second drive assembly 7 drives the sieve cylinder 2 to oscillate back and forth around its own axis, increasing the chance of the rapeseed contacting the first sieve holes 22, which helps reduce clogging and effectively improves the screening efficiency and quality of the rapeseed.
[0034] Specifically, refer to Figure 1 The second drive assembly 7 includes a rotary motor 71, a second rotating rod 72, a first connecting rod 73, and a second connecting rod 74. The second rotating rod 72 is rotatably connected to the bracket 6, and is parallel to the first rotating rod 73. The rotary motor 71 is bolted to the bracket 6, and its rotating shaft is coaxially connected to the second rotating rod 72. One end of the first connecting rod 73 is welded to the second rotating rod 72, and the other end is rotatably connected to the second connecting rod 74. A fixing column 24 is welded and fixed to the outer side of the bottom wall of the screen cylinder 2, and the fixing column 24 is parallel to the axis of the screen cylinder 2. The other end of the second connecting rod 74 is rotatably connected to the fixing column 24.
[0035] The rotating motor 71 starts and drives the second rotating rod 72 to rotate, causing the first connecting rod 73, which is fixedly connected to it, to rotate accordingly. The other end of the first connecting rod 73 is rotatably connected to the second connecting rod 74, thereby pushing the second connecting rod 74 to reciprocate in the vertical direction. Since the other end of the second connecting rod 74 is rotatably connected to the fixed column 24 on the bottom wall of the screen cylinder 2, this reciprocating motion is converted into the reciprocating swing of the screen cylinder 2 around its own axis, thereby realizing the functional requirement of the second driving component 7 to drive the screen cylinder 2 to reciprocate around its own axis. The structure is relatively simple and easy to use.
[0036] The first drive assembly 5 includes a first gear 51 and a second gear 52. The first gear 51 is coaxially connected to the second rotating rod 72, and the second gear 52 is coaxially connected to the first rotating rod 3. The first gear 51 and the second gear 52 mesh. When the rotating motor 71 starts and drives the second rotating rod 72 to rotate, the meshing transmission of the first gear 51 and the second gear 52 synchronously drives the first rotating rod 3 to rotate, thereby driving the rotation of the first rotating rod 3. The gear transmission method can effectively transmit a large torque, ensuring the stable operation of the equipment under high load, and also ensuring the effective operation of the stirring blades 31 inside the screen cylinder 2, enhancing the screening efficiency and quality of rapeseed.
[0037] In addition, refer to Figure 1-2To further optimize the screening effect, a sliding groove 14 is provided on one side wall of the housing 1 below the screen cylinder 2. The sliding groove 14 is set at a certain angle with the horizontal direction; in this embodiment, the angle is 10°. A second screen plate 8 is slidably inserted into the sliding groove 14. The diameter of the screen holes on the second screen plate 8 is set to be smaller than the diameter of the first screen hole 22. A first outlet is provided on the other side wall of the housing 1 near the lower end of the second screen plate 8, and a rotatable baffle 9 is provided on the first outlet. A third drive assembly 10 is provided on the bracket 6 for driving the second screen plate 8 to reciprocate.
[0038] The third drive assembly 10 includes a third rotating rod 101, a cam 102, a protrusion 103, and a power component. An elastic element 104, specifically a spring, is provided within the slide groove 14. One end of the elastic element 104 is connected to the second sieve plate 8, and the other end is connected to the inner wall of the slide groove 14. The elastic element 104 has a tendency to disengage the second sieve plate 8 from the slide groove 14. The third rotating rod 101 is rotatably connected to the bracket 6. The cam 102 is located at the bottom of the third rotating rod 101. The protrusion 103 is located on the second sieve plate 8, extending through the slide groove 14, and abuts against the peripheral wall of the cam 102. The power component drives the third rotating rod 101 to rotate. When the third rotating rod 101 is driven to rotate by the power component, the cam 102 pushes the protrusion 103, thereby causing the second sieve plate 8 to reciprocate within the slide groove 14, achieving secondary screening of the rapeseed and further improving the screening effect.
[0039] The power unit includes a driving bevel gear 105 and a driven bevel gear 106. The driving bevel gear 105 is coaxially connected to the first rotating rod 3, and the driven bevel gear 106 is coaxially connected to the third rotating rod 101. The driving bevel gear 105 and the driven bevel gear 106 mesh. When the first rotating rod 3 rotates, it drives the driving bevel gear 105 to rotate, which in turn drives the driven bevel gear 106 to rotate, thereby driving the third rotating rod 101 to rotate. This reduces the power source and saves on power costs.
[0040] The implementation principle of the rapeseed sorting machine in this embodiment is as follows: During use, rapeseed is fed into the machine casing 1 through the feed inlet 11. After the rapeseed falls into the sieve cylinder 2, the rotating motor 71 is started, driving the second rotating rod 72 to rotate. This causes the first connecting rod 73 to rotate around the axis of the second rotating rod 72. The other end of the first connecting rod 73 is rotatably connected to the second connecting rod 74, thus pushing the second connecting rod 74 to reciprocate vertically. Since the other end of the second connecting rod 74 is rotatably connected to the fixed column 24 on the bottom wall of the sieve cylinder 2, this reciprocating motion is converted into the reciprocating oscillation of the sieve cylinder 2 around its own axis, thereby filtering and sorting the rapeseed. Simultaneously, when the second rotating rod 72 rotates, under the meshing transmission of the first gear 51 and the second gear 52, it drives the first rotating rod 3 to rotate, thereby driving the stirring blades 31 to rotate, ensuring that the rapeseed inside the sieve cylinder 2 is fully stirred, thus releasing light impurities such as dust mixed in with the rapeseed. Furthermore, the rotation of the first rotating rod 3 will drive the fan blade 4 to rotate and generate airflow, thereby blowing light impurities out of the sieve cylinder 2 and discharging them through the dust removal hole 23, improving the problem that the rapeseed is in a state of accumulation when it falls and the impurity removal effect is not ideal.
[0041] In addition, qualified rapeseed after stirring and air separation will fall through the first screen hole 22 on the circumferential wall of the screen cylinder into the second screen plate 8 in the lower space. Through the meshing transmission of the active bevel gear 105 and the driven bevel gear 106, the third rotating rod 101 is driven to rotate, which in turn drives the cam 102 to periodically push the protrusion 103, realizing the reciprocating movement of the second screen plate 8 in the slide 14, thereby performing secondary screening of rapeseed and achieving a high-efficiency screening effect. Rapeseed of different particle sizes are discharged through the first outlet and the discharge port 13 respectively, realizing the screening of rapeseed of different grades.
[0042] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
