Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically to a nut grading and screening drum. Background Technology

[0002] Nut grading and sorting rollers are specialized equipment used in nut processing. They play an important role in the nut processing industry by classifying and sorting nuts of different sizes, shapes, and weights to meet the needs of grading and processing nuts of different qualities. This facilitates different processing and sales requirements and enhances the market competitiveness of nuts of varying qualities.

[0003] When using a drum sorter to grade and screen nuts, some nuts can easily get stuck inside the screen holes when they come into contact with the inside of the sorting drum. This can easily cause blockage of the screen holes, affecting sorting efficiency and accuracy. Furthermore, when nut particles are stuck in the screen holes, the force of the squeezing through the screen holes and the collision with other nuts can easily cause the nuts to break, resulting in nut damage and increasing nut loss during the sorting process. Utility Model Content

[0004] The purpose of this invention is to provide a nut grading and screening roller to solve the problem mentioned in the background art that when using a roller sorter to grade and screen nuts, nut particles are easily stuck in the sieve holes, causing blockage and affecting the efficiency and effect of screening. It also increases the probability of nut collision, which can easily lead to nut breakage and increase nut loss during the screening process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a nut grading and screening roller, including a frame, a screening cylinder is provided inside the frame, and an auxiliary component for retracting stuck nuts is provided on the outer wall of the screening cylinder. The auxiliary component includes a mounting bracket provided on the outer wall of the screening cylinder, and a plurality of slots are provided on one side of the mounting bracket. An infrared sensor is provided inside each of the plurality of slots. The mounting bracket has multiple sliding grooves on one side, and each sliding groove has a slider inside. One end of each slider has a positioning frame, the positioning frame has a fixed shaft inside, the outer wall of the fixed shaft has an extension rod, and the other end of the extension rod has a rubber block.

[0006] Preferably, the screening cylinder is rotatably connected to the inner wall of the frame via a drive shaft, the mounting frame is connected to the frame via bolts, and the mounting frame is located on one side of the screening cylinder, with one side of the mounting frame having an arc angle and corresponding to the screening cylinder.

[0007] Preferably, the plurality of the hole and groove arrays are distributed on one side of the mounting frame, and the angle of the hole and groove corresponds to the sieve holes on the outer wall of the screening cylinder. The infrared sensor is embedded and connected to the inner wall of the hole and groove, and its angle corresponds to the screening cylinder.

[0008] Preferably, the plurality of the chute arrays are distributed on the side of the mounting frame near the screening cylinder, and the distribution interval corresponds to the slot. One end of the chute is an open structure and communicates with the screening hole angle on the outer wall of the screening cylinder.

[0009] Preferably, the slider is located inside the slide groove and is slidably connected to the inner wall of the slide groove. The positioning frame is connected to the outer wall of the slider and has an arc-shaped structure at one end. The fixed shaft is located inside the positioning frame and is rotatably connected to the inner wall of the positioning frame through a spring shaft.

[0010] Preferably, one end of the extension rod is connected to the outer wall of the fixed shaft and moves in conjunction with the fixed shaft, while the other end extends to the outside and is connected to the rubber block. The extension rod and the rubber block slide and extend within the groove via a slider.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting a mounting bracket on one side of the screening cylinder, with the curvature of the mounting bracket corresponding to the angle of the screening cylinder, and by reserving a slot on the side of the mounting bracket close to the screening cylinder, an infrared sensor is installed in the slot. The infrared sensor can detect the external screening holes when the screening cylinder rotates. When a nut is stuck in the screening hole, the infrared sensor can detect it and issue a reminder.

[0012] 2. By setting a chute on one side of the mounting frame, and installing an extension rod and rubber block on the outside of the slider inside the chute, and electrically connecting the slider to the infrared sensor, when a nut is detected, the slider is controlled to drive the extension rod to extend and approach the screening hole, thereby agitating the nuts in the screening hole, causing the stuck nuts to be pushed back into the screening cylinder, thus cleaning the nuts, reducing the time of nut jamming, and ensuring the screening performance of the screening cylinder.

[0013] This invention uses infrared sensing to detect nuts stuck on the screening cylinder, and controls a lever to move closer to the screening cylinder via the sensing signal, thereby pushing the stuck nuts back into the screening cylinder. This effectively prevents nuts from getting stuck for a long time, ensures the normal use of the screening holes, and guarantees the screening effect. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0018] Please see Figures 1-3 The nut grading and sorting roller includes a frame 1, inside which a sorting cylinder 2 is installed. The sorting holes inside the sorting cylinder 2 are designed for segmented grading. The sorting cylinder 2 can be rotated to sort nuts. The outer wall of the sorting cylinder 2 is provided with an auxiliary component for retracting stuck nuts. The auxiliary component includes a mounting bracket 3 installed on the outer wall of the sorting cylinder 2. The mounting bracket 3 is connected to the frame 1 and is located on one side of the sorting cylinder 2, with one side angle corresponding to the arc of the sorting cylinder 2. One side of the mounting bracket 3 is provided with multiple slots 4 for installing infrared sensors 401. The installation angle of the infrared sensors 401 corresponds to the sorting holes in the sorting cylinder 2. Each of the multiple slots 4 is provided with an infrared sensor 401. The infrared sensors 401 can detect and sense the sorting holes when the sorting cylinder 2 rotates. When there are nuts stuck in the sorting holes, the infrared sensors 401 can detect and sense the nuts stuck in the sorting holes.

[0019] The screening cylinder 2 is rotatably connected to the inner wall of the frame 1 via a drive shaft. The mounting frame 3 is connected to the frame 1 via bolts, and the mounting frame 3 is located on one side of the screening cylinder 2. One side of the mounting frame 3 has an arc angle and corresponds to the screening cylinder 2. Multiple slots 4 are arrayed on one side of the mounting frame 3, and the angle of the slots 4 corresponds to the sieve holes on the outer wall of the screening cylinder 2. The infrared sensor 401 is embedded and connected to the inner wall of the slots 4, and its angle corresponds to the screening cylinder 2.

[0020] Specifically: When using the product, first place the nuts to be screened into the screening cylinder 2, and then drive the screening cylinder 2 to rotate through the drive shaft. With the different sizes of screening holes in the screening cylinder 2, the nuts can be screened into different grades. During the screening process, the infrared sensor 401 in the mounting bracket 3 on one side of the screening cylinder 2 conducts infrared sensing with the inside of the screening holes. When a nut is stuck in the screening hole, the infrared sensor 401 can sense the nut, thereby judging the state inside the screening hole and giving a reminder when the nut is stuck.

[0021] Please see Figure 4 and Figure 5 The mounting frame 3 has multiple sliding grooves 5 on one side. The distribution spacing between the multiple sliding grooves 5 corresponds to the distribution spacing of the holes 4, and the angle between the sliding grooves 5 and the holes 4 corresponds. Each of the multiple sliding grooves 5 has a slider 6 inside. The slider 6 can slide in the sliding groove 5, thereby driving the extension rod 701 to extend and retract in the sliding groove 5. One end of the slider 6 is provided with a positioning frame 601 for supporting the fixed shaft 7. The fixed shaft 7 is provided inside the positioning frame 601. The fixed shaft 7 can rotate through a spring shaft, and the support direction of the spring shaft is opposite to the rotation direction of the screening cylinder 2. The outer wall of the fixed shaft 7 is provided with an extension rod 701. The other end of the extension rod 701 is provided with a rubber block 8. The rubber block 8 is made of flexible material, which can not only ensure support but also deform when it comes into contact with the nuts.

[0022] Multiple chutes 5 are arrayed on the side of the mounting frame 3 near the screening cylinder 2, and their distribution intervals correspond to the slots 4. One end of the chutes 5 is an open structure and communicates with the screening holes on the outer wall of the screening cylinder 2 at an angle. The slider 6 is located inside the chutes 5 and is slidably connected to the inner wall of the chutes 5. The positioning frame 601 is connected to the outer wall of the slider 6 and has an arc-shaped structure at one end. The fixed shaft 7 is located inside the positioning frame 601 and is rotatably connected to the inner wall of the positioning frame 601 through a spring shaft. One end of the extension rod 701 is connected to the outer wall of the fixed shaft 7 and moves in conjunction with the fixed shaft 7. The other end extends to the outside and is connected to the rubber block 8. The extension rod 701 and the rubber block 8 slide and extend within the chutes 5 through the slider 6.

[0023] Specifically: When the infrared sensor 401 detects a stuck nut in the screening hole, the slider 6 is electrically controlled to slide outward in the groove 5. In conjunction with the positioning frame 601, the extension rod 701 and the rubber block 8 extend and approach the screening cylinder 2. When the screening hole with the stuck nut approaches, the rubber block 8 abuts against the stuck nut, thereby pushing the nut back into the screening cylinder 2. This cleans the stuck nut, prevents the nut from being stuck for a long time, ensures the unobstructed screening hole, and ensures the grading and screening effect of the screening cylinder 2 on the nuts.
