Description

Technical Field

[0001] This utility model relates to the field of nut shell separation technology, and in particular to a photoelectric color sorting device for walnut kernels. Background Technology

[0002] Walnut kernels are the edible part inside the walnut fruit, commonly known as "walnut meat." They are typically light brown, crisp in texture, and have a rich, aromatic flavor. They are rich in various nutrients, such as healthy fats, proteins, vitamins, and minerals. A walnut kernel photoelectric color sorting device is a machine that uses photoelectric technology to screen and sort walnut kernels. It collects information such as the color, shape, and surface defects of the kernels, analyzes the data using optical sensors and a high-resolution camera, and then automatically separates qualified kernels from unqualified kernels according to set standards.

[0003] The photoelectric color sorting device for walnut kernels uses photoelectric technology to automatically classify walnut kernels. The device captures images of walnut kernels through a high-resolution camera, and then uses image processing algorithms to analyze the color, shape, and defects of each walnut kernel. According to the set standards, the sorting system automatically identifies qualified and unqualified walnut kernels and uses mechanical devices to guide them to different collection containers, thereby achieving an efficient and accurate automatic sorting process.

[0004] In existing technologies, some photoelectric color sorting devices have certain limitations in practical applications, which makes walnut kernels prone to clumping at the feed inlet, resulting in the color sorting device being unable to accurately identify and sort them. Therefore, in order to address the above shortcomings, a photoelectric color sorting device for walnut kernels is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a photoelectric color sorting device for walnut kernels, which aims to improve the problem of walnut kernels not being able to prevent clumping in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A photoelectric color sorting and sorting device for walnut kernels includes a base, a support frame fixedly connected to the top of the base, a material distribution mechanism fixedly connected inside the support frame, a connecting column fixedly connected inside the support frame, and an anti-breakage mechanism fixedly connected to the outside of the connecting column.

[0008] The material distribution mechanism includes a feed inlet, the outside of which is fixedly connected to the inside of the support frame. A drive assembly is fixedly connected to the right side of the outside of the feed inlet. A stirring column is rotatably connected inside the feed inlet. Multiple flow dividers are fixedly connected inside the feed inlet. Multiple rotating columns are rotatably connected inside the feed inlet. A baffle plate is fixedly connected to the outside of the rotating columns. A transmission assembly is fixedly connected to the outside of the feed inlet.

[0009] As a further description of the above technical solution:

[0010] The anti-shatter mechanism includes multiple U-shaped plates. The U-shaped plates are fixedly connected to the outside of the connecting column. A placement column is placed inside the U-shaped plate. A guide cloth is sleeved on the outside of the placement column. Pressing components are slidably connected to the left and right sides inside the U-shaped plates.

[0011] As a further description of the above technical solution:

[0012] The drive assembly includes a support plate, the outside of which is fixedly connected to the right side of the base, and a motor is fixedly connected to the top of the support plate. The drive end of the motor is fixedly connected to the outside of the stirring column.

[0013] As a further description of the above technical solution:

[0014] The transmission assembly includes a housing, the outside of which is fixedly connected to the outside of the feed inlet, a second motor fixedly connected inside the housing, a rotating shaft fixedly connected to the drive end of the second motor, a belt assembly fixedly connected to the outside of the rotating shaft, and the inside of the belt assembly fixedly connected to the outside of the rotating column.

[0015] As a further description of the above technical solution:

[0016] The pressing assembly includes a limiting plate, the outside of which is slidably connected to the inside of the U-shaped plate, and springs are fixedly connected to the left and right sides of the bottom of the limiting plate, with the other end of the springs fixedly connected to the inside of the U-shaped plate.

[0017] As a further description of the above technical solution:

[0018] A collection box is fixedly connected to the top of the base, and the interior of the collection box is placed outside the guide cloth;

[0019] As a further description of the above technical solution:

[0020] A color sorting machine is fixedly connected inside the support frame, and an inclined plate is fixedly connected outside the color sorting machine.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the rotating shaft is driven by the starting motor, which in turn drives the multiple rotating columns to rotate the baffle plate under the transmission of multiple belt sets. This allows the walnut kernels to enter the feed inlet and pass through the stirring column and the diverting plate, preventing the walnut kernels from clumping before entering the feed inlet. This effectively prevents the walnut kernels from clumping, ensures that the material is evenly dispersed, thereby improving the photoelectric color sorting accuracy and sorting efficiency, while reducing the risk of blockage.

[0023] 2. In this utility model, the limiting plate is pushed upward by pulling the spring, and then the placement column covered with the guide cloth is placed into the U-shaped plate. Then the force on the limiting plate is withdrawn, so that the limiting plate restricts the placement column. Thus, the sorted walnut kernels can fall into the inside of the collection box along the guide cloth, preventing the walnut kernels from breaking. This effectively reduces the impact force of the falling walnut kernels and avoids breakage caused by mechanical collision. At the same time, it ensures that the sorted materials slide into the collection box intact and smoothly, ensuring the quality of the finished product. Attached Figure Description

The base 1 has a rectangular frame structure and is rust-proofed, providing good stability and load-bearing capacity. A support frame 2 is fixedly connected to the top of the base 1. The support frame 2 has a rectangular frame structure and is used to support and fix various components. A material distribution mechanism is fixedly connected inside the support frame 2. The material distribution mechanism includes a feed inlet 3, which has a rectangular funnel shape and is used to receive walnut kernel raw materials. The outside of the feed inlet 3 is fixedly connected to the inside of the support frame 2. A drive assembly is fixedly connected to the right side of the outside of the feed inlet 3. The drive assembly includes a support plate 4, which has a rectangular plate shape. The outside of the support plate 4 is fixedly connected to the right side of the outside of the base 1. A motor 5 is fixedly connected to the top of the support plate 4, providing stable power output. The drive end of the motor 5 is fixedly connected to the outside of the stirring column 6.

[0033] A stirring column 6, cylindrical in shape, is rotatably connected inside the feed inlet 3. This column is used to stir and disperse the walnut kernels, ensuring uniform distribution of the raw materials. Multiple diversion plates 7, rectangular in shape, are fixedly connected inside the feed inlet 3 to evenly distribute the walnut kernel raw materials to different areas. Multiple rotating columns 11 are also rotatably connected inside the feed inlet 3. Driven by a motor 9, multiple belt sets 13 rotate the rotating columns 11, achieving quantitative feeding of the walnut kernels. The rotating columns 11 are cylindrical in shape. The cylindrical rotating column 11 is fixedly connected to a baffle plate 12, which rotates and closes to further separate the walnut kernels and prevent the raw materials from accumulating. The feed inlet 3 is fixedly connected to a transfer assembly, which includes a housing 8. The housing 8 is a rectangular box and is fixedly connected to the outside of the feed inlet 3. The housing 8 is fixedly connected to a motor 9, which can provide stable power output. The drive end of the motor 9 is fixedly connected to a rotating shaft 10. The rotating shaft 10 is fixedly connected to a belt assembly 13, and the belt assembly 13 is fixedly connected to the outside of the rotating column 11.

[0034] Reference Figure 1 , Figure 4 and Figure 5The support frame 2 is internally fixedly connected to a connecting column 16, which is cylindrical in shape. An anti-breakage mechanism is externally fixedly connected to the connecting column 16. The anti-breakage mechanism includes multiple U-shaped plates 17, which are U-shaped. The U-shaped plates 17 are externally fixedly connected to the outside of the connecting column 16. A placement column 18 is placed inside the U-shaped plate 17. The placement column 18 is cylindrical in shape. A guide cloth 19 is sleeved on the outside of the placement column 18 to guide the flow of walnut kernels. The guide cloth 19 is used to prevent the walnut kernels from breaking during the sorting process. The support frame 2 is internally fixedly connected to a color sorting machine 14, which can accurately sort walnut kernels according to their color and shape, thereby improving the sorting quality. An inclined plate 15 is externally fixedly connected to the color sorting machine 14 to guide the sorted walnut kernels into the collection box 20.

[0035] The inner left and right sides of the U-shaped plate 17 are slidably connected to pressing components. The pressing components include a limiting plate 22, which is rectangular in shape. The outer side of the limiting plate 22 is slidably connected to the inside of the U-shaped plate 17. The bottom left and right sides of the limiting plate 22 are fixedly connected to springs 21. Due to the elasticity of the springs 21, the limiting plate 22 can move up and down, providing buffering and pressing functions to ensure the stability of the walnut kernels during the sorting process. The other end of the springs 21 is fixedly connected to the inside of the U-shaped plate 17. The top of the base 1 is fixedly connected to a collection box 20, which is rectangular in shape and used to collect the sorted walnut kernels. The inside of the collection box 20 is placed outside the guide cloth 19.

[0036] Working principle: Walnut kernel raw materials first enter the device through the feed inlet 3. Motor 2 9 drives the belt group 13 through the rotating shaft 10, so that multiple rotating columns 11 rotate synchronously. The baffle plate 12 fixed on them forms an intermittent feeding channel to realize quantitative feeding. Then, at this time, motor 1 5 drives the stirring column 6 to rotate, which, together with the diversion plate 7 inside the feed inlet 3, stirs and disperses the material. The dispersed walnut kernels enter the color sorting machine 14 for photoelectric identification and sorting. Qualified materials are guided by the anti-crushing mechanism at the connecting column 16 through the inclined plate 15.

[0037] The walnut kernels slide down the surface of the guide cloth 19 covering the outside of the placement column 18. Pulling the spring 21 pushes the limiting plate 22 upward, and then the placement column 18 covered with the guide cloth 19 is placed into the U-shaped plate 17. Then the force on the limiting plate 22 is withdrawn, so that the limiting plate 22 restricts the placement column 18, realizing quick installation and positioning. Finally, the sorted walnut kernels slide smoothly along the guide cloth 19 into the collection box 20 at the top of the base 1 for collection, realizing a soft landing of the material.
