Description

Technical Field

[0001] This utility model relates to the field of rapeseed screening technology, and more specifically to a screening device for rapeseed processing. Background Technology

[0002] Rapeseed, also known as rapeseed, is the seed of the cruciferous crop rapeseed. Rapeseed has relatively long pods, produces many pods, and the seeds are plump. Rapeseed is the raw material for rapeseed oil, which is used daily. The oil content varies slightly depending on the type of rapeseed. It is one of the main oil crops and honey crops in our daily lives. Its seeds are one of the main raw materials for extracting oil. Before processing rapeseed, it is necessary to screen it.

[0003] When screening rapeseed, wind separation is used, which involves using wind power to blow away the remaining rapeseed pods. However, in actual screening, wind separation can only blow away the smaller rapeseed pods. It is not very effective in removing some larger rapeseed pods and stones. Utility Model Content

[0004] The purpose of this invention is to provide a screening device for rapeseed processing, in order to solve the problem mentioned in the background art that wind screening can only blow away the smaller rapeseed pods, and the removal effect on some larger rapeseed pods and stones is not ideal.

[0005] To achieve the above objectives, this utility model provides a screening device for rapeseed processing, comprising a housing, a screen cylinder rotatably disposed inside the housing, the screen cylinder having multiple screen holes on its surface, a motor fixedly disposed on the outer wall of the housing, the output end of the motor passing through the side wall of the housing and fixedly disposed on a rotating shaft, one end of the rotating shaft being fixed to the outer wall of the screen cylinder, an L-shaped branch pipe fixedly disposed on the side wall of the housing away from the motor, the bottom end of the L-shaped branch pipe being rotatably connected to the side wall of the screen cylinder, a feeding hopper fixedly disposed at the top end of the L-shaped branch pipe, a fixing plate fixedly disposed on the inner side of the housing above the screen cylinder, multiple sleeves fixedly disposed at the bottom of the fixing plate, each sleeve having a spring fixedly disposed inside, a telescopic column slidably disposed at the bottom end of each sleeve, the bottom end of the spring being fixed to the telescopic column, and multiple protrusions for abutting the telescopic column being fixedly disposed on the outer surface of the screen cylinder.

[0006] By adopting the above scheme, the motor drives the rotating shaft to rotate, which in turn drives the screen cylinder to rotate to screen the rapeseed. The rapeseed passes through the screen holes, while the rapeseed pods and stones are trapped inside the screen cylinder. The rotation of the screen cylinder drives multiple baffles to rotate, which in turn pushes the rapeseed to tumble, thereby preventing the rapeseed from accumulating and causing blockages. This effectively removes impurities such as rapeseed pods and stones, and improves the efficiency of rapeseed screening.

[0007] As a further improvement to this technical solution, an inclined guide plate is fixed on the inner side of the housing below the screen cylinder, and a discharge port for the guide plate to pass through is opened on the side wall of the housing.

[0008] By adopting the above method, the rapeseed that falls off the screen lands on the surface of the guide plate and rolls down the surface of the guide plate before being discharged through the outlet, which facilitates the collection of the screened rapeseed.

[0009] As a further improvement to this technical solution, the side wall of the screen cylinder is provided with a cleaning port, and a baffle is provided at the cleaning port on the side wall of the screen cylinder. The baffle is connected and fixed to the outer side wall of the screen cylinder by bolts, and the side wall of the shell is provided with an opening that matches the cleaning port.

[0010] By adopting the above method, the screen cylinder drives the baffle to rotate to the opening, the bolts on the baffle are removed, the baffle is then removed, and tools such as brushes are used to reach into the screen cylinder to remove the impurities. The impurities fall onto the surface of the guide plate and are finally discharged through the outlet.

[0011] As a further improvement to this technical solution, multiple baffles are fixedly arranged on the inner surface of the screen cylinder, and the multiple baffles are arranged in a ring array.

[0012] By adopting the above scheme, the rotation of the screen cylinder drives the rotation of multiple baffles, which in turn push the rapeseed to tumble, thereby preventing the rapeseed from accumulating and causing blockage.

[0013] As a further improvement to this technical solution, the longitudinal section of the convex strip is a quarter-circle structure, the bottom end of the telescopic column is provided with an oblique opening for contacting the convex strip, and the arc surface of the convex strip smoothly transitions with the surface of the screen cylinder.

[0014] By adopting the above solution, the contact and compression between the telescopic column and the convex strip are smoother, avoiding greater resistance to the rotation of the screen cylinder.

[0015] As a further improvement to this technical solution, the side wall of the screen cylinder is provided with a bearing, and the L-shaped branch pipe is rotatably engaged with the side wall of the screen cylinder through the bearing. The L-shaped branch pipe penetrates the side wall of the screen cylinder and extends into the screen cylinder.

[0016] By adopting the above solution, the screen cylinder is supported by L-shaped branch pipes, which also facilitates the rotation of the screen cylinder.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a screen cylinder, the motor drives the rotating shaft to rotate, which in turn drives the screen cylinder to rotate and screen the rapeseed. The rapeseed passes through the screen holes, while the rapeseed pods and stones are trapped inside the screen cylinder. The rotation of the screen cylinder drives multiple baffles to rotate, which pushes the rapeseed to tumble, thereby preventing the rapeseed from accumulating and causing blockage. This effectively removes impurities such as rapeseed pods and stones, and improves the efficiency of rapeseed screening.

[0018] 2. By setting a convex strip, the convex strip squeezes the telescopic column and drives the telescopic column to move upward. The telescopic column compresses the spring. As the convex strip rotates, it will separate from the telescopic column. At this time, the restoring force of the spring will drive the telescopic column to move downward quickly. Then, under the action of inertia, the telescopic column will knock the outer surface of the screen cylinder, thereby shaking off the rapeseed pods stuck in the screen holes and reducing the clogging of the screen holes.

[0023] Please see Figures 1-3 As shown, this utility model provides a screening device for rapeseed processing, including a housing 1. A screen cylinder 2 is rotatably mounted inside the housing 1. The screen cylinder 2 is horizontally positioned and closed at both ends. Multiple screen holes 7 are opened on the surface of the screen cylinder 2. The diameter of the screen holes 7 is slightly larger than the diameter of the rapeseed, allowing the rapeseed to pass through the screen holes 7, while the rapeseed pods and stones are trapped inside the screen cylinder 2. A motor 3 is fixedly mounted on the outer wall of the housing 1. The output end of the motor 3 passes through the side wall of the housing 1 and is fixedly mounted on a rotating shaft 4. One end of the rotating shaft 4 is fixed to the outer wall of the screen cylinder 2. The motor 3 drives the rotating shaft 4 to rotate, which in turn drives the screen cylinder 2 to rotate and screen the rapeseed. An L-shaped branch pipe 5 is fixedly mounted on the side wall of the housing 1 away from the motor 3. The bottom end of the L-shaped branch pipe 5 is rotatably connected to the side wall of the screen cylinder 2. A bearing 17 is provided on the side wall of the screen cylinder 2, and the L-shaped branch pipe 5 is rotatably engaged with the side wall of the screen cylinder 2 through the bearing 17. The screen cylinder 2 is supported by an L-shaped branch pipe 5, which facilitates the rotation of the screen cylinder 2. The L-shaped branch pipe 5 passes through the side wall of the screen cylinder 2 and extends into the screen cylinder 2. A feeding hopper 6 is fixedly installed at the top of the L-shaped branch pipe 5. Rapeseed is poured into the feeding hopper 6 and slides into the screen cylinder 2 through the L-shaped branch pipe 5. Multiple partitions 16 are fixedly installed on the inner surface of the screen cylinder 2. The multiple partitions 16 are arranged in a ring array. The rotation of the screen cylinder 2 drives the multiple partitions 16 to rotate, and the multiple partitions 16 push the rapeseed to roll, thereby avoiding the accumulation of rapeseed and blockage. An inclined guide plate 13 is fixedly installed on the inner side of the shell 1 below the screen cylinder 2. The side wall of the shell 1 has an outlet 14 for the guide plate 13 to pass through. The rapeseed that falls off the screen falls on the surface of the guide plate 13 and rolls down the surface of the guide plate 13, and is discharged through the outlet 14 for collection.

[0024] Please see Figures 2-4As shown, a fixing plate 8 is fixedly installed on the inner side of the shell 1 above the screen cylinder 2. Multiple sleeves 9 are fixedly installed at the bottom of the fixing plate 8, and springs 10 are fixedly installed inside each sleeve 9. Telescopic columns 11 are slidably fitted onto the bottom ends of each sleeve 9. The bottom ends of the springs 10 are fixed to the telescopic columns 11, and the springs 10 are in a stretched state. A gap is left between the bottom end of the telescopic columns 11 and the outer surface of the screen cylinder 2. Multiple protrusions 12 for abutting the telescopic columns 11 are fixedly installed on the outer surface of the screen cylinder 2. The longitudinal cross-section of the protrusions 12 is a quarter-circle structure. The screen cylinder 2 drives the protrusions 12 to rotate. When the protrusions 12 rotate to the upper end of the screen cylinder 2, they will contact the bottom end of the telescopic columns 11. The protrusions 12 squeeze the telescopic columns 11 and drive the telescopic columns 11 to move upwards. The telescopic columns 11 compress the springs 10. As the protrusions 12 rotate, they will separate from the telescopic columns 11. At this time, the restoring force of the springs 10 drives the telescopic columns 11 to move rapidly downwards. Then, under the action of inertia, the telescopic columns 11 push against the outer surface of the screen cylinder 2. The telescopic column 11 intermittently strikes the outer surface of the sieve cylinder 2 by setting multiple protrusions 12, thereby shaking off the rapeseed pods stuck in the sieve holes 7 and reducing the clogging of the sieve holes 7. The bottom end of the telescopic column 11 is provided with an oblique opening for contacting the protrusions 12. The arc surface of the protrusions 12 smoothly transitions with the surface of the sieve cylinder 2, making the contact and compression between the telescopic column 11 and the protrusions 12 smoother and avoiding greater resistance to the rotation of the sieve cylinder 2. The side wall of the sieve cylinder 2 has a dirt removal port. A baffle 15 is provided on the side wall at the impurity removal port. The baffle 15 is connected and fixed to the outer side wall of the screen cylinder 2 by bolts. The side wall of the housing 1 has an opening 18 that matches the impurity removal port. When it is necessary to clean the impurities in the screen cylinder 2 after use, the screen cylinder 2 drives the baffle 15 to rotate to the opening 18, the bolts on the baffle 15 are removed, and then the baffle 15 is removed. Tools such as brushes are used to reach into the screen cylinder 2 to remove the impurities. The impurities fall on the surface of the guide plate 13 and are finally discharged through the discharge port 14.

[0025] The specific working principle of this utility model is as follows: Rapeseed is poured into the feeding hopper 6, and the rapeseed slides into the screen cylinder 2 through the L-shaped branch pipe 5. The motor 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the screen cylinder 2 to rotate to screen the rapeseed. The rapeseed passes through the screen holes 7, while the rapeseed pods and stones are trapped inside the screen cylinder 2. The rapeseed that falls off the screen falls on the surface of the guide plate 13 and rolls down the surface of the guide plate 13, and is then discharged through the discharge port 14. The screen cylinder 2 drives the convex strip 12 to rotate. When the convex strip 12... When the sieve cylinder 2 rotates to the upper end, it will contact the bottom end of the telescopic column 11. The protrusion 12 squeezes the telescopic column 11 and drives the telescopic column 11 to move upward. The telescopic column 11 compresses the spring 10. As the protrusion 12 rotates, it will separate from the telescopic column 11. At this time, the restoring force of the spring 10 will drive the telescopic column 11 to move downward quickly. Then, the telescopic column 11 will strike the outer surface of the sieve cylinder 2 under the action of inertia, thereby shaking off the rapeseed pods stuck in the sieve holes 7 and reducing the blockage of the sieve holes 7.
