Description

Technical Field

[0001] The utility model relates to the technical field of seed screening, and more specifically to a grading device for vegetable seed processing. Background Art

[0002] In the actual vegetable planting work, seeds have always played an important role in the emergence rate, especially in rural areas, where many farmers use their own seed-keeping method to plant vegetables, and need to screen the seeds. At this time, a good vegetable seed screening machine is needed. At present, the existing vegetable seed screening machine, such as the utility model patent with application number 2022227060487, discloses a vegetable seed selection device, which includes a screening machine and a hopper. The hopper is fixedly mounted on the end face of the screening machine. The side wall of the screening machine is provided with a cleaning mechanism. The cleaning mechanism includes a speed-regulating fan, an air pipe and two vertical plates. The speed-regulating fan is fixedly mounted on the side wall of the screening machine. The air pipe is connected to one end of the speed-regulating fan. The arc surface of the air pipe is sleeved with a fixed sleeve. The two vertical plates are respectively fixedly mounted on both sides of the hopper. A storage frame is fixedly mounted on the side of the two vertical plates close to each other. The fixed sleeve is fixedly connected to the bottom surface of the storage frame. The side wall of the hopper is fixedly connected with an inclined plate, and the end face of the inclined plate is provided with a collecting frame.

[0003] Although it can be provided with a speed-adjustable fan, an air pipe, and a double-sided sticker, and the speed-adjustable fan can transmit airflow to the air pipe, so that the airflow in the air pipe blows toward the seeds that slip from the storage frame, thereby blowing out the empty shell seeds mixed in the seeds, and under the action of the double-sided sticker, the dust blown between the seeds can be bonded together, which prevents the dust from drifting to a certain extent. However, it is not convenient to achieve graded screening, it is not convenient to screen the leaves in the seeds, it is not convenient to achieve more efficient and labor-saving screening, and the screening efficiency is affected. At the same time, the structure is complex and the cost is high, and it is not suitable for seed screening work with simple requirements. The existing patent is a vegetable seed screening machine, and the patent authorization number CN219356897U can effectively guarantee the overall screening quality, avoid seed spilling, and achieve auxiliary three-level screening.

[0004] However, in patent authorization No. CN219356897U, when screening vegetable seeds, the vegetable seeds to be screened are placed on the inner side of the device, and the vegetable seeds are taken out after screening, and then the next batch of seeds are screened. Continuous screening of vegetable seeds cannot be achieved, which reduces the screening efficiency of vegetable seeds. Therefore, we propose a grading equipment for vegetable seed processing to solve the above-mentioned problems. Utility Model Content

A guide column 17 slidably connected to the guide hole 16 is welded at the root of the outer wall of the screening box 1, and a spring 18 is arranged between the base 14 and the screening box 1.

[0038] It should be noted that when the grading equipment for vegetable seed processing is in use, the vegetable seeds to be graded are continuously added to the inner side of the screening box 1 through the feed port 2, and the vibration motor 12 is turned on at the same time. Under the action of the eccentric vibrator 13, the guide column 17 cooperates with the guide hole 16 set at the bracket 15 to make the screening box 1 vibrate up and down under the elastic force of the spring 18, so that the screen plate 3 set at an angle screens the vegetable seeds and guides them at the same time. The intercepted first-level vegetable seeds are discharged through the first-level discharge port 5, and the screened vegetable seeds fall onto the guide plate 4 set at an angle, and then are discharged through the second-level discharge port 6. While realizing the grading of vegetable seeds, it can also realize continuous screening of vegetable seeds, thereby improving the efficiency of vegetable seed processing.
