Description

Technical Field

[0001] This utility model relates to the field of weed seed sorting and processing technology, specifically a slope-feeding weed seed sorting device. Background Technology

[0002] In existing technologies, the collected grain materials usually contain some mixed weed seeds. These weed seeds seriously affect the planting and consumption of the grain materials, so it is necessary to sort out these weed seeds.

[0003] Existing weed seed sorting technology and equipment, such as the "A Vibrating Separator for Tiny Weed Seeds" disclosed in Publication No. CN204276337U, includes a vibrating platform and at least one rolling plate. The rolling plate slopes downwards from one end to the other, has at least one opening, a mixture recovery tank below the opening, and a seed collection tank at the final end of the rolling plate. A vibrating shaft is mounted on the vibrating platform, and the rolling plate is driven to vibrate by the vibrating shaft. This invention has a simple structure and is easy to operate. Through the vibration distance of multiple rolling plates, it can effectively separate and collect tiny weed seeds such as amaranth from impurities such as dust, grain seed coats, and fine broken particles. The separation of tiny weed seeds is clean, fast, and highly automated, making it very suitable for laboratory use in the weed quarantine process of inbound and outbound goods, especially for weed quarantine work on ships carrying large quantities of bulk grain.

[0004] For example, the "Portable Weed Seed Capture and Separation Device" disclosed in Publication No. CN220188036U includes a collection mechanism housed within an outer casing and a collection handle at the rear end of the casing. The collection mechanism comprises a motor, impellers, an air guide hood, an air collecting hood, a collection tank, a cap, and a suction pipe. The air guide hood is coaxially mounted on the rear section of the outer casing via a bracket. An air collecting hood is located in the outer casing in front of the air guide hood. A pressurized air chamber for mounting impellers is formed by the gap between the air guide hood and the air collecting hood. Several impellers are coaxially mounted in the pressurized air chamber. The motor is coaxially mounted within the air guide hood, with its shaft extending through the air guide hood and connecting to each impeller. The collection tank is located in the front section of the outer casing, with an exhaust port at the rear end connecting to the air collecting hood and a suction pipe at the front end. The collection handle contains a control device and a power supply. This invention can quickly capture and classify weed seeds, greatly improving detection and collection efficiency, and is convenient to use.

[0005] In the above technical solutions, one solution uses vibration to separate weed seeds for weed quarantine purposes; the other solution uses wind power to separate weed seeds. However, the efficiency and quality of sorting in both solutions need improvement. For example, the vibration-based sorting method cannot effectively separate mixed weed seeds; and the wind-powered method of blowing materials and weed seeds apart also cannot effectively separate mixed weed seeds.

[0006] Therefore, in order to solve the above problems, it is necessary to develop a slope-feed weed seed sorting device with a reasonable structure that can effectively improve sorting efficiency and quality. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing a slope-feed weed seed sorting device; its technical solution is as follows:

[0008] A slope-feeding weed seed sorting device includes a feeding plate, which is inclined and has several parallel partitions installed inside the feeding plate, thereby dividing the area inside the feeding plate into several inclined feeding ramps. Each feeding ramp contains material, which is fed from top to bottom under the action of gravity.

[0009] The upper end of the feeding plate is also equipped with a camera recognition device corresponding to the number and position of the feeding ramps. The recognition direction of the camera recognition device is aligned with the feeding ramp below, and the weed seeds in the material are identified by taking pictures.

[0010] Furthermore, each feeding ramp of the feeding plate is equipped with a separation base plate, which is located on the lower side of the camera recognition device of each ramp. The upper end of the separation base plate is installed correspondingly to the bottom of the feeding ramp through a hinge. A drive assembly is also provided below each feeding ramp. The drive assembly can drive the separation base plate to flip downward based on the hinge.

[0011] When the camera recognition device on the feeding ramp detects that the material is mixed with weed seeds, the drive component is activated to drive the separation base plate to flip downwards, so that the material mixed with weed seeds falls from the position of the opened separation base plate and is removed; then the separation base plate is reset under the action of the drive component.

[0012] Furthermore, there are three partitions on the feeding plate and four feeding ramps on the feeding plate, with the separation bottom plate in the same position on each feeding ramp.

[0013] Furthermore, a sorting frame is provided below the separating base plate, and the size of the sorting frame is set accordingly so that the sorting frame covers the entire area of ​​the separating base plate, and the material after each separating base plate is opened falls into the sorting frame.

[0014] Furthermore, a mounting frame is provided at the front end of the feeding ramp, and the mounting frame is correspondingly mounted on the partition; the camera recognition device is fixed on the mounting frame, and the camera recognition range of the camera recognition device and the width of the feeding ramp are correspondingly set, so that the camera recognition device on each feeding ramp can recognize all the materials passing on the feeding ramp.

[0015] Furthermore, a spreading plate is provided at the front end of the feeding plate, and the spreading plate is fixed on the partition to spread the material in the feeding ramp accordingly.

[0016] Furthermore, a vibration motor is also installed on the feeding plate to achieve feeding.

[0031] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented under the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a slope-feeding weed seed sorting device includes a feeding plate 1, which is inclined and has several parallel partitions 2 installed inside the feeding plate 1, thereby dividing the area inside the feeding plate 1 into several inclined feeding ramps 3. Each feeding ramp 3 contains material, which is fed from top to bottom in the feeding ramp 3 under the action of gravity.

[0033] The upper end of the feeding plate 1 is also equipped with a camera recognition device 4 corresponding to the number and position of the feeding ramp 3. The recognition direction of the camera recognition device 4 is aligned with the feeding ramp 3 below, and the weed seeds in the material are identified by taking pictures.

[0034] Furthermore, each feeding ramp 3 of the feeding plate 1 is equipped with a separation base plate 5. The separation base plate 5 is located on the lower side of the camera recognition device 4 of each ramp. The upper end of the separation base plate 5 is installed correspondingly to the bottom of the feeding ramp 3 through the hinge 6. A drive assembly is also provided below each feeding ramp 3. The drive assembly can drive the separation base plate 5 to flip downward based on the hinge 6.

[0035] When the camera recognition device 4 on the feeding ramp 3 detects that the material is mixed with weed seeds, the drive component is activated to drive the separation base plate 5 to flip downwards, so that the material mixed with weed seeds falls from the position of the opened separation base plate 5 and is removed; then the separation base plate 5 is reset under the action of the drive component.

[0036] There are three partitions 2 on the feeding plate 1, and four feeding ramps 3 on the feeding plate 1. The separation bottom plate 5 on each feeding ramp 3 is in the same position.

[0037] A sorting frame 7 is also provided below the separating base plate 5, and the size of the sorting frame 7 is set accordingly so that the sorting frame 7 covers the entire area of ​​the separating base plate 5, and the material after each separating base plate 5 is opened falls into the sorting frame 7.

[0038] The front end of the feeding ramp 3 is also provided with a mounting frame 8, which is correspondingly set on the partition plate 2; and the camera recognition device 4 is fixed on the mounting frame 8, and the camera recognition range of the camera recognition device 4 and the width of the feeding ramp 3 are set accordingly, so that the camera recognition device 4 on each feeding ramp 3 can recognize all the materials passing on the feeding ramp 3.

[0039] The front end of the feeding plate 1 is also provided with a slab plate 9, which is fixed on the partition plate 2 to flatten the material in the feeding ramp 3.

[0040] A vibration motor 10 is also installed on the feeding plate 1, and the feeding is achieved by the vibration motor 10.

[0041] like Figure 4 and Figure 5As shown, the drive assembly includes a horizontally arranged drive mechanism 11, and a slider 13 is mounted on the main shaft 12 of the drive mechanism 11 via a hinge 6; while the separation base plate 5 is provided with a corresponding slide groove 14, and the slider 13 is correspondingly embedded in the slide groove 14; the main shaft 12 of the drive mechanism 11 can drive the separation base plate 5 to open and close on the feeding ramp 3 accordingly.

[0042] Each feeding ramp 3 has a corresponding set of drive components on its separation base plate 5, and each set of drive components is a separate control mechanism.

[0043] The end of the separating base plate 5 is set as an inclined ramp structure 15, which is correspondingly fixed to the feeding ramp 3 by the ramp structure 15.

[0044] The specific working process of the technical solution of this device is as follows: First, the technical solution of this device is a slope feeding structure. Multiple partitions are set on the feeding plate, thus forming multiple feeding slopes. The material is fed downward on the feeding slope by gravity and vibration motor.

[0045] Furthermore, during the downward feeding process, the material first encounters a spreading plate. After passing through the spreading plate, the material on the feeding ramp is spread into a thinner layer and then continues to be fed downwards. When the material passes through the camera recognition device, it will be photographed and identified by the camera recognition device. Usually, the material is of the same color and relatively uniform size, while the color and size of the weed seeds are different from those of the material. Therefore, weed seeds can be identified based on their different colors and sizes.

[0046] Once the camera detection device identifies weed seeds, the drive mechanism is activated, causing the main shaft to move and the separating plate to flip downwards. The material mixed with weed seeds then falls from the opened position of the separating plate into the sorting box below. Afterwards, the drive mechanism drives the separating plate to reset, and the material continues to be fed on the feeding ramp.

[0047] The weed seeds that fall into the sorting box can be picked out by workers. All four feeding ramps of this device can open and close the separation bottom plate, and can be used to sort weed seeds. The structure is reasonable.

[0048] Furthermore, the device features a well-designed structure for the separation base plate. The separation base plate is moved by a drive mechanism, with a slider mounted on the end of the drive mechanism's main shaft via a hinge. Correspondingly, a groove is provided at the lower end of the separation base plate, corresponding to the slider's position. The slider is embedded in the groove, allowing it to move and thus rotate the separation base plate. The end of the separation base plate is also designed as a ramp, making it easier to mount the separation base plate onto the feeding ramp. The structure is therefore well-designed.

[0049] The above-described specific embodiments are merely preferred embodiments of this utility model and are not intended to limit the implementation of this utility model or the scope of the claims. All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
