Description

Technical Field

[0001] This utility model relates to the technical field of transmission devices, and in particular to a vibrating and shaking feeding device for spectral detection of red pine nuts. Background Technology

[0002] In the field of quality inspection of nuts such as pine nuts, it is usually necessary to acquire spectral images of a large number of nuts to extract characteristic parameters for analysis. This process requires laying the nuts flat on a platform and arranging them according to a specific pattern, ensuring that adjacent rows of nuts are spaced a certain distance apart and do not overlap, so that the hyperspectral camera or image acquisition device can clearly and accurately acquire image information.

[0003] Chinese utility model patent CN218859665U discloses a conveyor device for preventing nut stacking during nut detection. The device includes a conveyor belt and an anti-stacking mechanism. The anti-stacking mechanism comprises a drive motor, two telescopic supports, a support shaft, N rubber rollers, and N+1 separator blocks. The two telescopic supports are vertically mounted on both sides of the conveyor belt, and the two ends of the support shaft are rotatably mounted on the tops of the two telescopic supports. The drive motor is mounted on one of the telescopic supports, and its drive shaft is connected to one end of the support shaft via a coupling. The N+1 separator blocks and N rubber rollers are alternately fitted onto the support shaft along its axial direction. The maximum outer diameter of each separator block is larger than the outer diameter of the rubber roller. While this device achieves the function of separating nuts, it lacks a continuous and uniform feeding mechanism. In actual operation, relying on manual feeding directly onto the conveyor belt is not only labor-intensive and inefficient, but also makes it difficult to control the uniformity of the feeding amount, and the subsequent anti-stacking mechanism is also difficult to effectively handle.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0028] Please refer to Figures 1 to 8 As shown, a vibrating and shaking feeding device for spectral detection of red pine nuts is illustrated. It includes: a main frame 1, a vibrating plate 2, a vibrating motor 3, a feeding hopper 4, a conveying device 5, and a material-leveling mechanism 6. The vibrating plate 2 and the feeding hopper 4 are both mounted on the main frame 1, with the discharge port of the feeding hopper 4 located above the vibrating plate 2. The vibrating motor 3 is mounted at the bottom of the vibrating plate 2, and each end of the rotor shaft of the vibrating motor 3 has a set of adjustable eccentric blocks installed. The centrifugal force generated by the high-speed rotation of the shaft and the eccentric blocks is used to generate the excitation force. The conveying device 5 is located in front of the main frame 1. The front end of the vibrating plate 2 is located above the rear end of the conveying device 5, and the vibrating plate 2 transfers the material from the feeding hopper 4 to the conveying device 5. The material-leveling mechanism 6 is mounted on the conveying device 5 and is used to level the material on the conveying device 5.

[0029] Furthermore, in a preferred embodiment, a spring 7 is also included, with each corner of the bottom of the feed hopper 4 being mounted on the main frame 1 by a spring 7.

[0030] Furthermore, in a preferred embodiment, the main frame 1 includes four vertically arranged columns 11 and four horizontally arranged crossbars 12. The four columns 11 are arranged in a rectangular shape, and the four crossbars 12 are respectively connected between two adjacent columns 11. The top of any column 11 is connected to the bottom of the vibrating plate 2 through a spring 7. When the vibration motor 3 works, it drives the vibrating plate 2 to vibrate. The spring 7 can buffer the vibration transmitted by the vibration motor 3 through the vibrating plate 2, reduce the resonance of the main frame 1, and thus ensure its stability.

[0031] Furthermore, in a preferred embodiment, it also includes support rods 8, with the left and right sides of the feed hopper 4 respectively connected to the left and right sides of the main frame 1 via two support rods 8; the lower end of the left support rod 8 is welded to the left crossbar 12, and the upper end of the left support rod 8 is welded to the left outer wall of the feed hopper 4; the lower end of the right support rod 8 is welded to the right crossbar 12, and the upper end of the right support rod 8 is welded to the right outer wall of the feed hopper 4.

[0032] Furthermore, in a preferred embodiment, a connecting rod 9 is also included. The front end of the main frame 1 is connected to the conveying device 5 through two symmetrically arranged connecting rods 9. One end of any connecting rod 9 is welded to the main frame 1, and the other end of any connecting rod 9 is detachably connected to the conveying device 5 by bolts. The connecting rod 9 plays an auxiliary positioning role, accurately determining the relative position between the main frame 1 and the conveying device 5, thereby ensuring that the vibrating plate 2 can maintain an appropriate positional relationship with the conveying device 5, so as to achieve smooth docking between the two and efficiently convey materials.

[0033] Furthermore, in a preferred embodiment, the conveying device 5 includes a left side plate 51, a right side plate 52, a drive roller, a driven roller, a support roller, a conveyor belt 53, support legs 54, and a first motor 55. The bottom end of the left side plate 51 is connected to the bottom end of the right side plate 52 through multiple support legs 54. The drive roller, the driven roller, and multiple support rollers are rotatably connected between the left side plate 51 and the right side plate 52. The drive roller is located at the front end of the conveying device 5, the driven roller is located at the rear end of the conveying device 5, and the multiple support rollers are located between the drive roller and the driven roller. The conveyor belt 53 is sleeved on the drive roller, the driven roller, and the multiple support rollers. The first motor 55 is mounted on the left side plate 51, and the power output end of the first motor 55 is connected to one end of the drive roller through belt drive.

[0034] Furthermore, in a preferred embodiment, the top of the left side plate 51 and the top of the right side plate 52 are both higher than the upper surface of the conveyor belt 53; since the feeding mechanism 6 plays a certain limiting role on the material, the material will move laterally. The design that the top of the left side plate 51 and the top of the right side plate 52 are both higher than the upper surface of the conveyor belt 53 can prevent the material from falling from both sides of the conveying device 5 during the transmission process.

[0035] Furthermore, in a preferred embodiment, the feeding mechanism 6 includes a rotating shaft 61, a second motor 62, partition blocks 63, rubber rollers 64, bearing seats 65, and connecting members 66. Multiple partition blocks 63 and multiple rubber rollers 64 are alternately sleeved on the rotating shaft 61 along its axial direction. The outer diameter of the partition blocks 63 is larger than the outer diameter of the rubber rollers 64. The second motor 62 is mounted on the right side plate 52, and its output shaft is connected to one end of the rotating shaft 61. The bearing seats 65 are detachably mounted on the left side plate 51 by bolts. The other end of the rotating shaft 61 is rotatably mounted on the bearing seats 65 via the connecting members 66. The rotating shaft 61 is located above the upper surface of the conveyor belt 53. The axis of the rotating shaft 61 is set along the left and right. The rotation direction of the rotating shaft 61 is opposite to the rotation direction of the conveyor belt 53. The rotation of the rotating shaft 61 plays a role in assisting the material to pass through. Any two adjacent partition blocks 63, the conveyor belt 53 and the rubber rollers 64 between the two partition blocks 63 together form a channel for material to pass through. This channel is used to guide the material and prevent material stacking and effective arrangement during the transmission process. The partition blocks 63 and the rubber rollers 64 can be set with different specifications to change the size of the channel, so as to adapt to different kinds of nuts.

[0036] Furthermore, in a preferred embodiment, two symmetrically distributed frustum sections 631 are respectively provided at the left and right ends of the separator block 63. The outer diameter of the frustum section 631 gradually decreases from the inside to the outside, and the two frustum sections 631 are connected by a cylindrical section 632. The frustum section 631 has a guiding effect on the transmission of the nuts to be tested, so that the nuts move to the rubber roller 64 between the two separator blocks 63. Under the drive of the rubber roller 64 and the conveyor belt 53, the nuts move from the rear of the rotating shaft 61 to the front of it. And due to the separating effect of the separator block 63, a certain distance is left between the two adjacent rows of nuts to be tested laterally.

[0037] Furthermore, in a preferred embodiment, a groove 511 is provided on the left side plate 51, and the bearing seat 65 is installed in the groove 511 by bolts; the other end of the rotating shaft 61 is detachably connected to the connector 66.

[0038] Furthermore, in a preferred embodiment, the right side wall of the bearing seat 65 and the right side wall of the left side plate 51 are located on the same plane; the bearing seat 65 seals the groove 511, which can prevent material from falling out of the groove 511.

[0039] Furthermore, in a preferred embodiment, the connector 66 includes an inner ring, an outer ring, balls, and a cage. A plurality of balls are disposed between the inner ring and the outer ring, and the plurality of balls are evenly spaced along the circumference of the inner ring. The cage is mounted on the plurality of balls for limiting the movement of the plurality of balls.

[0040] Furthermore, in a preferred embodiment, the connector 66 is a bearing. The outer ring of the bearing is interference-fitted with the bearing housing 65, and the inner ring of the bearing is clearance-fitted with the rotating shaft 61. The clearance-fit of the rotating shaft 61 is for the purpose of facilitating disassembly and assembly. When disassembly and assembly are required, the bolts connecting the bearing housing 65 and the groove 511 are removed, and the bearing housing 65 is pulled to the left. The bearing housing 65 drives the bearing to move axially along the rotating shaft 61. After complete disassembly, the separator 63 and the rubber roller 64 can be removed one by one after passing through the groove 511. Then, the separator 63 and the rubber roller 64 of new size are replaced, and then the bearing housing 65 and the bearing are reinstalled.

[0041] Furthermore, in a preferred embodiment, the feeding mechanism 6 further includes a limiting nut 67, which is screwed to the other end of the rotating shaft 61. The limiting nut 67 is located on the right side of the bearing seat 65 and is lower than the leftmost partition block 63. A limiting block 68 is provided at one end of the rotating shaft 61 near the right side plate 52. Multiple partition blocks 63 and rubber rollers 64 are arranged between the limiting block 68 and the limiting nut 67. The limiting nut 67 and the limiting block 68 clamp the partition blocks 63 and the rubber rollers 64 to prevent them from moving.

[0042] Furthermore, in a preferred embodiment, the vibrating plate 2 is inclined to the horizontal plane, and the rear end of the vibrating plate 2 is higher than its front end. During the vibration process, the vibrating plate 2 assists the material to slide freely onto the conveying device 5. Furthermore, the angle between the vibrating plate 2 and the horizontal plane is less than or equal to 5°. The inclination angle of the vibrating plate 2 is controlled within a reasonable range to prevent the material flow rate from being too fast and causing material accumulation. The left end, right end and rear end of the vibrating plate 2 are all provided with baffles 21, which play a role in limiting the material falling from the feed hopper 4.

[0043] Working principle:

[0044] Nuts, such as whole pine nuts in their shells or pine kernels, are fed into the feed hopper 4. The nuts slide down through the discharge port at the bottom of the feed hopper 4 onto the vibrating plate 2. The vibrating motor 3 drives the vibrating plate 2 to vibrate. The nuts on the vibrating plate 2 are dispersed after being shaken and shaken, and continue to slide down onto the conveyor device 5. As the conveyor belt 53 rotates, the nuts are conveyed forward. When they pass through the feeding mechanism 6, the nuts are moved and separated by the combined action of the separator 63, the rubber roller 64, and the conveyor belt 53. The rubber roller 64 limits the height to prevent stacking, and the separator 63 guides the nuts to be arranged. There is a certain space between adjacent rows of nuts, making the nuts in the image captured by the spectral camera clearer and more distinguishable.

[0045] In summary, this utility model provides a uniform and continuous feeding function, which provides a more uniform material transfer for subsequent material feeding operations and can effectively prevent material jamming.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
