Abstract
Description
Technical Field
[0001] This utility model relates to the field of prickly pear screening technology, and in particular to a grading screening device. Background Technology
[0002] After the prickly pear is harvested, there are usually prickly pears of different sizes, ripeness and quality. Grading and sorting devices can help to classify the prickly pears according to the size, shape, weight and other standards, which can ensure that the subsequent processing is more accurate and efficient.
[0003] A prior art patent document, CN211637348U, discloses a prickly pear grading and sorting device, comprising: a roller conveyor, which is divided into a screening section and a grading section along the transport direction. The rollers in the screening section are close to each other, while the spacing between the rollers in the grading section increases sequentially along the transport direction. Multiple upward-facing receiving grooves are sequentially arranged below the grading section along the transport direction. This utility model provides a prickly pear grading and sorting device composed of a roller conveyor, which not only performs grading and sorting but also transports and transfers the fruit. The screening section is mainly used by workers on both sides to examine the appearance of the prickly pears, thus filtering out bad or rotten fruit. In the grading section, due to the increased spacing between the rollers, smaller-diameter prickly pears fall first into the lower receiving groove, while larger-diameter prickly pears fall last. The spacing between the rollers allows for efficient and convenient sorting of the prickly pears by diameter.
[0004] The existing prickly pear grading and screening devices do not have a mechanism to rotate the prickly pears, which makes the prickly pear screening process inefficient, resulting in missed or incorrect screening and low practicality. Utility Model Content

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0024] Please see Figures 1 to 3 This utility model provides a technical solution: a grading and screening device, including a base plate 1, which is the basic support part of the entire device and its main function is to provide a stable support surface. A support frame 2 is fixedly connected to the top of the base plate 1. The support frame 2 is used to support the motor. A screening mechanism 3 is fixedly connected to the top of the support frame 2. The screening mechanism 3 is used to efficiently turn the prickly pear over and then screen the prickly pear through a variety of screening holes of different sizes on the screening barrel 7. A washing tank 15 is fixedly connected to the top of the base plate 1. The washing tank 15 is used to wash the prickly pear. A washing mechanism 16 is fixedly connected to the front side of the washing tank 15. The washing mechanism 16 is used to efficiently wash the prickly pear and then drain it.
[0025] The screening mechanism 3 includes a drive assembly for rotating the screening barrel 7 and the rotating blades 8. The drive assembly includes a motor 4, the bottom of which is fixedly connected to the top of the support frame 2. The motor 4 is the power source for the screening mechanism 3. Driven by the drive plate 6, it rotates the screening barrel 7, and drives the rotating blades 8 through the output shaft 5. The output end of the motor 4 is fixedly connected to the output shaft 5, with the outer side of the output shaft 5 contacting the inner side of the screening barrel 7. The motor 4 also outputs power through the output shaft 5 to drive... The rotation of the rotating blades 8 flips the prickly pear during the screening process. A drive plate 6 is fixedly connected to the drive assembly, and a screening barrel 7 is fixedly connected to the front of the drive plate 6. The outer side of the screening barrel 7 contacts the top of the collection box 9. The screening barrel 7 is a key component in the entire screening process, used to contain materials and screen them by rotation. The screening barrel 7 has various sizes of screening holes inside, allowing screening according to different hole diameters to screen prickly pears of different sizes. The screened prickly pears are then fed into the collection box 9, which is separated by the sorting plate 10. The drive assembly is fixedly connected to the drive assembly. A rotating blade 8 is fixedly connected to the bottom plate 1. The outer side of the rotating blade 8 contacts the inner side of the screening barrel 7. Driven by the output shaft 5, the rotating blade 8 rotates to flip the prickly pears being screened inside, making the screening more efficient. A collection box 9 is fixedly connected to the top of the bottom plate 1. Two sorting plates 10 are fixedly connected inside the collection box 9. The collection box 9 is used to collect the screened prickly pears. The sorting plates 10 separate the collection box 9 into different sizes of prickly pears. Multiple rotating doors 11 are rotatably connected to the inner side of the collection box 9. The rotating doors 11 can be rotated open to facilitate the removal of the sorted prickly pears. The top of the collection box 9 is fixedly connected to a cleaning component, which includes multiple telescopic columns 12. The bottom of the multiple telescopic columns 12 is fixedly connected to the top of the collection box 9, and the top of the multiple telescopic columns 12 is fixedly connected to a sliding shell 13. The inner side of the sliding shell 13 is fixedly connected to a brush 14. The function of the cleaning component is to clean the screening box 7 after use to prevent material accumulation and blockage. The telescopic columns 12 can adjust the cleaning height, and the brush 14 inside the sliding shell 13 can effectively clean the residual material in the screening box 7 and ensure the normal operation of the equipment.
[0026] like Figure 1 , Figure 4 and Figure 5As shown, a grading and screening device includes a cleaning mechanism 16 comprising a second motor 17. The inner side of the second motor 17 is fixedly connected to the outer side of a cleaning tank 15. An output shaft 18 is fixedly connected to the output end of the second motor 17. The outer side of the output shaft 18 contacts the interior of the cleaning tank 15. The second motor 17 provides power to the cleaning tank 15, driving cams 19 inside the cleaning tank 15 via the output shaft 18. The rotation of the cams 19 causes the cleaning frame 20 to vibrate, resulting in more efficient cleaning. Multiple cams 19 are fixedly connected to the outer side of the output shaft 18. The top of the cams 19 contacts the bottom of the cleaning tank 15. The cams 19 can rotate under the drive of the output shaft 18, causing the cleaning frame 20 to vibrate. A sliding rod 24 is slidably connected inside the cleaning tank 15. The outer side of the sliding rod 24 is fixedly connected to the interior of a drive ring 23. The sliding rod 24 can vibrate the cleaning frame 20. When in motion, it slides inside the washing tank 15 to maintain stability. A washing frame 20 is fixedly connected to the outside of the sliding rod 24. The washing frame 20 contains prickly pears for washing. It can rise under the drive of the cylinder 22 to drain the washed prickly pears. Support blocks 21 are fixedly connected to both sides of the washing tank 15. The support blocks 21 are used to support the cylinder 22. The bottom of the support blocks 21 is fixedly connected to the cylinder 22. The output end of the cylinder 22 is fixedly connected to the drive ring 23. The cylinder 22 drives the sliding rod 24 and the connected washing frame 20 to rise through the drive ring 23 to drain the washed prickly pears. Two suction pipes 25 are fixedly connected to the side of the screening tank 7 away from the drive plate 6. The two suction pipes 25 can suck the washed and drained prickly pears into the screening tank 7 to start screening. The bottom of the two suction pipes 25 is fixedly connected to the support plate 26 to support the suction pipes 25.
[0027] Working principle: Inside the screening mechanism 3, the motor 4 on the support frame 2 is started. The motor 4 drives the screening barrel 7 to rotate through the drive plate 6. At the same time, the output shaft 5 of the motor 4 drives the rotating blade 8 to rotate. The rotating blade 8 rotates inside the screening barrel 7 and flips the prickly pear. Since the screening barrel 7 has a variety of screening holes of different sizes, as the screening barrel 7 rotates, the prickly pears of different sizes pass through the corresponding screening holes in sequence under the action of centrifugal force and other forces, and fall into the collection box 9 separated by the classification plate 10 below, realizing graded collection. After collection, the rotating door 11 can be rotated to easily take out the classified prickly pears. After the screening work is completed, the cleaning component on the top of the collection box 9 is activated, the telescopic column 12 adjusts the height, and the brush 14 in the sliding shell 13 cleans the screening barrel 7 to avoid material accumulation and blockage, and ensure the normal operation of the equipment next time.
[0028] The prickly pears to be processed are placed in the washing tank 15, and the motor 17 is started. The motor 17 serves as the power source for the washing mechanism 16, and the output shaft 18 at the output end rotates accordingly, driving multiple cams 19 fixed on the outside of the output shaft 18 to rotate. When the cams 19 rotate, they contact the bottom of the washing tank 15 and generate force, causing the washing frame 20 to vibrate, thereby achieving a more thorough cleaning of the prickly pears. During the vibration of the washing frame 20, the sliding rod 24 fixed on the outside of the washing frame 20 slides inside the washing tank 15 to keep the washing frame 20 stable. After the cleaning is completed, the cylinder 22 at the bottom of the support block 21 is started, driving the sliding rod 24 and the washing frame 20 to rise through the drive ring 23, so that the cleaned prickly pears are removed from the water surface for draining. The drained prickly pears are sucked into the screening bucket 7 by the suction pipe 25 supported by the support plate 26 for screening.
[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
