Through lateral movement, the pushing plate pushes out sunflower seeds suspended in the designated area, which are then discharged and collected by the guide plate.

Description

Technical Field

[0001] This utility model relates to the field of sunflower seed screening technology, specifically a sunflower seed processing and screening device. Background Technology

[0002] When processing sunflower seeds, in order to avoid empty and broken seeds, a sunflower seed screening device is usually used for screening. When using wind power for separation, the airflow speed and the ratio of particle mass / volume determine the suspension state when the wind acts on the sunflower seeds. Light particles (such as empty sunflower seeds or dust) are more affected by the drag force of the airflow due to their small mass, and are more easily lifted by the airflow and kept in suspension.

[0003] Chinese Patent Publication No. CN216937098U discloses a "Sunflower Seed Processing and Screening Device," which includes a riser pipe. A storage bin is fixedly connected to the bottom surface of the riser pipe, and a screen plate is movably connected to the inner wall of the bottom of the storage bin. A vibrating element is installed below the screen plate. A screening device is installed in the middle of the riser pipe, and the top of the riser pipe is set as an opening. A waste removal device is installed at the opening of the riser pipe. A feed pipe connected to the inside of the riser pipe is also fixedly connected to the surface of the riser pipe. The height of the feed pipe is lower than the height of the screening device. Through the setting of the vibrating element, the screening device, and the waste removal device, when the device is in use, it can first remove dust under the vibration of the screen plate, and then the sunflower seeds are vibrated and suspended in the air by the vibrating element. Due to the difference in size and weight, the height of sunflower seeds of different masses suspended is different. The sunflower seeds are screened by the screening device, and the empty sunflower seeds are very light.

[0004] In existing technologies, suspended sunflower seeds are blown out through a horizontal pipe using an intermittent air blower. However, the airflow blown out by the air blower can cause disturbances, which can easily lead to the mixing of the sunflower seeds after they have separated. Utility Model Content

[0005] The purpose of this utility model is to provide a sieving device for sunflower seed processing, in order to solve the problem in the above-mentioned background technology where suspended sunflower seeds are blown out through a horizontal pipe using an intermittent blower, but the airflow blown out by the blower will cause disturbance, which will easily lead to the mixing of the stratified sunflower seeds.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a sieving device for processing melon seeds, including a central cylinder, with lifting and adjusting components on both sides of the upper end of the central cylinder, which are used to adjust the height according to the needs; and a movable pushing component is provided on the inner side of the upper end of the central cylinder, which is used to push out the suspended melon seeds.

[0007] The lifting and adjusting assembly includes a movable frame, and movable sleeves are installed at the top and bottom of the movable frame. The movable sleeves are located inside the central cylinder. The lifting and adjusting assembly includes two sets of telescopic push rods, and the telescopic push rods are located on both sides of the upper end of the central cylinder. A movable plate is installed at the top of the output end of the telescopic push rod, and the movable plate is connected to both sides of the lower end of the movable frame.

[0008] The movable pusher assembly includes two sets of welding plates, which are located on the front and back of the movable frame. A drive shaft is provided in the middle of the welding plate and runs through the middle of the movable frame. Large gear plates are installed on the outer sides of both ends of the drive shaft, and C-shaped brackets are meshed on the top and bottom of the large gear plates. A fixed bracket is installed at the end of the C-shaped bracket, and a connecting plate is installed on the side of the fixed bracket near the movable frame. Connecting guide plates are installed on the front and back of the connecting plate, and a push plate is provided on the inner side of the end of the connecting guide plate. The connecting plate is located inside the movable frame.

[0009] Preferably, a feed inlet is provided on the right side of the central cylinder, and a separator is embedded in the bottom of the central cylinder. A guide air duct is installed at the bottom of the separator, and an industrial fan is provided at the input end of the guide air duct. A fan drive is provided on the front of the industrial fan.

[0010] Preferably, connecting brackets are installed on the front and back of the upper end of the central cylinder, and the connecting brackets are fixed to the external frame. An exhaust duct is installed on the inner side of the upper end of the connecting bracket, and an exhaust pipe is provided on the top of the exhaust duct.

[0011] Preferably, guide plates are installed on the upper left and lower right sides of the movable frame, and the guide plates are located below the connecting plate.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] First, this utility model has a movable pushing component installed. The welding plate can provide an installation position for the inner structure. The drive motor controls the rotation of the drive shaft, which in turn drives the C-shaped bracket to make lateral adjustments through two sets of large gear plates. During the adjustment, the connecting plate will drive the push plate to move laterally through the connecting guide plate. Since the push plate is in a vertical state, it will not have a significant impact on the airflow. By moving laterally, the push plate can push out the melon seeds suspended in the area and discharge them through the guide plate for collection.

[0017] Secondly, this utility model, by installing a lifting and adjusting component, addresses the issue that, due to the varying quality of melon seeds caused by different growing environments, the existing structure cannot adjust and control the height of the suspended melon seeds. By installing a telescopic push rod, the fixed block and the movable frame connected to the inner side can be vertically adjusted. During the adjustment process, the movable sleeve will slide stably along the inner side of the movable frame, thereby adjusting the position of the discharge port to a certain extent to adapt to the different qualities of melon seeds.

The industrial fan 104 at the bottom blows the seeds up and keeps them suspended. An external PLC controller controls the drive motor 502 to rotate, and the drive shaft 503 drives the large gear 504 to rotate. During rotation, the C-shaped bracket 5 is engaged and slides laterally along the limit sleeve 507. During adjustment, the C-shaped bracket 5 moves the connecting plate 6 laterally, thereby controlling the push plate 602 to push the suspended sunflower seeds to separate from the movable frame 3. After the airflow is lost, the seeds will automatically fall and be discharged along the guide plate 302. After discharge, the separation is repeated. When adjustment is needed, the PLC controller controls the telescopic push rod 402 to adjust the height of the movable frame 3 using the fixed block 401 to adapt to different needs.
