[0002] The seeds of safflower oil tea are of different sizes, so they need to be classified and screened during processing. Seeds of different sizes must be treated differently. Generally, screening machines are used for screening. The seeds are separated by sieves of different sizes and stored in different locations. After screening, they are manually recovered and processed.

[0003] The screening devices currently used have the following disadvantages:

[0004] 1. Lack of automatic seed screening and separate delivery of seeds of different sizes;

[0005] 2. It is inconvenient to continuously grade and screen different seeds and to carry out continuous processing and screening;

[0006] 3. Lack of conveying structure that does not affect the screening process. Summary of the invention

[0007] In view of this, the present invention provides a safflower camellia seed screening device to address the deficiencies in the above-mentioned prior art.

[0009] Optionally, a screening motor is fixedly arranged outside the side positioning ring on one side of the screening bin, and the screening motor is drivingly connected to a group of positioning shafts; three groups of partition edges are fixedly arranged at the bottom of the screening bin, and the side of the conveyor is located below the partition edges.

[0010] Optionally, a spacer ring for separating seeds is fixedly arranged inside the control gear ring.

[0011] Optionally, a conveyor belt is rotatably arranged in the middle of the conveyor; the right end of the conveyor extends outward, and the right side of the conveyor belt is inclined upward; a discharging motor is fixedly arranged outside the screening bin, and the discharging motor is synchronously connected with the pulley shafts of the three sets of conveyor belts.

[0012] Optionally, an input hopper is integrally provided at the front top of the feed channel; a discharge port is integrally provided at the rear bottom of the feed channel, two sets of side panels are hingedly provided on both sides of the discharge port, and the side panels are limited to rotate 0-70 degrees to both sides.

[0013] Optionally, a flip motor and a feed motor are staggered and fixedly arranged on the top of the motor frame; a drive gear ring is fixedly arranged outside the rearmost side feed channel, and a gear is arranged on the shaft end of the flip motor to mesh with the drive gear ring.

[0014] Optionally, the middle of the feed channel is a hollow structure and a screw propeller is rotatably arranged in cooperation with the bearing, and four groups of screw propellers are fixedly connected; the feed motor is transmission-connected to the screw propeller.

[0016] The beneficial effects are as follows:

[0017] 1. The control gear ring provides an automatic screening function. It can rotate continuously through the drive, and use the three screens between the four sets of control gear rings for graded screening. Seeds of different sizes are screened onto different conveyor belts. The conveyor belt is driven by the discharging motor to rotate, which can transport the seeds outward and raise the seeds. A receiving structure is set under the end of the conveyor belt to accommodate the seeds, which makes screening and collection very convenient.

[0018] 2. A feed channel is set up to provide a continuous screening function. The shape of the feed channel is controlled to cooperate with the spiral propeller to transport the seeds backwards. New seeds can be filled in each time a screening is completed to achieve continuous screening. There is no need to take out all the seeds and put them back in each time the screening is completed, thus achieving continuous and automated screening. In addition, the shape of the V-shaped connecting strip provides a centering guiding effect, which can make the seeds converge to the middle and ensure that the seeds fall into the input bucket.

[0019] 3. Side panels are set to provide a conveying structure that does not affect the screening process. When the input bucket is facing downward and the discharge port is facing upward, the two sets of side panels naturally fall down and close due to gravity, closing the feed channel to prevent seeds from entering the feed channel. After flipping half a circle, the side panels will automatically open by gravity, and then the front seeds can be transported backward using the auxiliary drive of the screw propeller to achieve feeding.

The shape of the V-shaped connecting strip 201 provides a central guiding effect, which can make the seeds converge to the middle and ensure that the seeds fall into the input bucket 401.

[0046] The cross-sectional shape of the V-shaped connecting strip 201 is generally set to be a strip shape, which can be adjusted to a shape more suitable for transportation as needed.

[0047] Embodiment 3: Based on Embodiment 1, the number of screening motors 106 is not limited to one, and the position of the screening motor 106 and the number of screening motors 106 installed can be adjusted according to power requirements, and different forms such as belt drive or chain drive can be used to achieve drive.

[0049] Then, the flip motor 701 is started to drive the driving gear ring 6 to rotate the feed channel 4 half a circle, so that the input bucket 401 faces downward. At this time, the two sets of side plates 403 fall down naturally under the influence of gravity, and the feed channel 4 is closed;

[0050] Then, the screening motor 106 is started to drive the positioning shaft 104 to rotate, and the positioning gear 105 is used to synchronously drive each group of control gear rings 2 to rotate, so as to flip and screen the seeds, and the seeds with particles smaller than the mesh will fall above the front conveyor belt 301;

[0051] The conveyor belt 301 is driven to rotate by the discharge motor 8 to transport the seeds outward and raise the seeds. A receiving structure is provided below the end of the conveyor belt 301 to receive the seeds.

[0052] After completing the first level of screening, the flip motor 701 is started to drive the driving gear ring 6 to rotate another half circle, and the side plate 403 will automatically open by gravity, and then the front side seeds can be transported backward by the auxiliary drive of the screw propeller 5 to achieve feeding, and then the above steps can be repeated to perform secondary screening, and the same steps can be used to perform third level screening; the remaining seeds can be transported to the storage bin 9 by the same steps, and when the storage bin 9 has reached the upper limit of storage, it can be directly used as a cart for transportation;

[0053] In the process of controlling the rotation of the gear ring 2, the V-shaped connecting strip 201 is used to drive the seeds to tilt upward for screening. When the input bucket 401 is facing upward, the V-shaped connecting strip 201 is also used to drive the seeds so that the seeds fall into the input bucket 401 for the effect of backward transportation. The shape of the V-shaped connecting strip 201 provides a central guiding effect, which can make the seeds converge to the middle and ensure that the seeds fall into the input bucket 401.

[0054] Each time feeding is performed, each group of input buckets 401 is set upwards. At this time, new seeds can be poured into the front input bucket 401, thereby realizing continuous screening. There is no need to take out all the seeds and put them back after each screening, thus realizing continuous and automated screening.
