Description

Technical Field

[0001] This utility model relates to the field of seed selection equipment technology, specifically to a seed screening device for Aquilaria sinensis. Background Technology

[0002] Costus root is a commonly used traditional Chinese medicine, mainly derived from the root of the Costus root plant (Aucklandia lappa). It has wide applications in traditional Chinese medicine, primarily for regulating qi and relieving pain, strengthening the spleen and aiding digestion.

[0003] The screening of Aucklandia lappa seeds is a crucial step in the planting process, directly impacting germination rate and subsequent growth. It can save on planting costs and make the planting process smoother. Screening removes defective seeds, thereby improving the overall seed quality. However, existing screening machines cannot control the flow rate and the feeding is not uniform during the seed feeding process, resulting in poor air separation effect. Utility Model Content

[0004] The purpose of this invention is to provide a seed screening device for Aquilaria sinensis, which aims to solve the problem in the above-mentioned background technology that the air separation is insufficient due to the excessive and uneven falling flow rate.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a seed screening device for *Saussurea costus*, comprising an air separator and a feed pipe extending through and connected to one side of the top of the air separator, and further comprising a slow and uniform feeding mechanism disposed at the bottom of the feed pipe. The slow and uniform feeding mechanism includes an adjustment mechanism for adjusting the seed feeding speed and a feeding mechanism for uniform seed feeding. The adjustment mechanism includes a connecting frame, a baffle, and a handle. The connecting frame is disposed on the outer side of the bottom of the feed pipe. The baffle is inserted into the inner side of the connecting frame and extends through the feed pipe to the inside of the feed pipe at one end. The handle is disposed at the other end of the baffle. One end of the baffle has a downwardly bent edge. The feeding mechanism includes a guide plate and a driving mechanism for driving the guide plate to reciprocate. The upper end of the guide plate is rotatably connected to the inner wall of the feed pipe and is disposed opposite to the bent edge of the baffle. A gap for seed feeding is formed between the bottom side of the guide plate and the bent edge of the baffle.

[0006] Furthermore, it also includes a connecting block located outside the feed pipe and at the upper end of the connecting frame, and a positioning rod inserted through the connecting block. The baffle has a positioning hole adapted to the positioning rod. The bottom end of the positioning rod passes through the interior of the connecting frame and is inserted into the corresponding positioning hole. A spring sleeved on the outside of the positioning rod is fixedly connected between the connecting block and the connecting frame.

[0007] Furthermore, the driving mechanism includes a motor and a rotating rod. The rotating rod is rotatably connected between the inner walls of the air separator and two symmetrically distributed cams are fixedly sleeved on the outer wall. The outer edge of the cams abuts against the bottom end of the guide plate. The motor is fixedly installed on the air separator and its output end is fixedly connected to the end of the rotating rod.

[0008] Furthermore, the inner side of the air separator is provided with vertical partitions and L-shaped partitions, which divide the inner cavity of the air separator into a superior seed chamber, a inferior seed chamber and a dust collection chamber from left to right. The top of the vertical partition is provided with a curved partition.

[0009] Furthermore, the left side of the air separator is provided with a first air inlet pipe and a second air inlet pipe from top to bottom. The air inlet direction of the first air inlet pipe acts on the upper part of the L-shaped partition, and the air inlet direction of the second air inlet pipe is along the tangent direction of the curved partition. The ends of the first air inlet pipe and the second air inlet pipe are both connected to a blower box.

[0010] This utility model has the following beneficial effects:

[0011] This utility model provides a screening device for Aquilaria sinensis seeds. The size of the feeding port can be adjusted by a set adjustment mechanism to regulate the feeding flow rate of the seeds and prevent uneven airflow penetration caused by an excessively thick material layer. Due to the reciprocating vibration of the guide plate, the feeding mechanism prevents the seeds from clogging at the feeding port, ensuring uniform feeding of the seeds during the feeding process. This ensures that the material is evenly distributed in the air classifier and fully contacts the airflow, thereby improving the sorting effect and air classifying efficiency.

Detailed Implementation

[0016] like Figures 1 to 3As shown, a seed screening device for *Saussurea costus* includes an air separator 1 and a feed pipe 2 that runs through and connects to one side of the top of the air separator 1. It also includes a slow and uniform feeding mechanism located at the bottom of the feed pipe 2. The slow and uniform feeding mechanism includes an adjustment mechanism for adjusting the seed feeding speed and a feeding mechanism for uniform seed feeding. The adjustment mechanism includes a connecting frame 3, a baffle 4, and a handle 5. The connecting frame 3 is located on the outer side of the bottom of the feed pipe 2. The baffle 4 is inserted inside the connecting frame 3, with one end passing through the feed pipe 2 and extending into the interior of the feed pipe 2. The handle 5 is located at the other end of the baffle 4. One end of the baffle 4 has a downwardly sloping bent edge 6. The device allows for adjustment of the position of the baffle 4. This allows for a thinner seed feed and better air separation. The feeding mechanism includes a guide plate 7 and a drive mechanism for driving the guide plate to reciprocate. The upper end of the guide plate 7 is rotatably connected to the inner wall of the feed pipe 2 and is positioned opposite to the bent edge 6 of the baffle. A gap for seed feeding is formed between the bottom side of the guide plate 7 and the bent edge 6. The guide plate 7 and the bent edge 6 are arranged in a V-shape. The sandalwood seeds slide along the inclined surfaces of the guide plate 7 and the bent edge 6 and fall through the gap between them. When the guide plate 7 reciprocates, it causes relative movement between the material at the bottom of the inner side of the feed pipe 2 and the guide plate 7, thereby ensuring that the sandalwood seeds are fed evenly.

[0017] It also includes a connecting block 8 located outside the feed pipe 2 and at the upper end of the connecting frame 3, and a positioning rod 9 inserted on the connecting block 8. The baffle 4 has a positioning hole 10 that matches the positioning rod 9. The bottom end of the positioning rod 10 passes through the interior of the connecting frame 3 and is inserted into the corresponding positioning hole 10. A spring 11 is fixedly connected between the connecting block 8 and the connecting frame 3 and sleeved on the outside of the positioning rod 9. Through the cooperation of the positioning rod 9 and the positioning hole 10, the baffle 4 is limited and fixed, making the baffle 4 more stable during use. When the baffle 4 is adjusted, the positioning hole 10 located inside the feed pipe 2 can be blocked with a plug to prevent seeds from getting stuck in the hole and causing cleaning trouble. When the positioning rod 9 is pulled, the spring 11 is compressed. When the positioning rod 9 is inserted into different positioning holes 10, the spring 11 is released to complete the positioning.

[0018] The drive mechanism includes a motor 12 and a rotating rod 13. The rotating rod 13 is rotatably connected between the inner walls of the air separator 1 and two symmetrically distributed cams 14 are fixedly sleeved on the outer wall. The outer edge of the cams 14 abuts against the bottom end of the guide plate 7. The motor 12 is fixedly installed on the air separator 1 and its output end is fixedly connected to the end of the rotating rod 13.

[0019] The inner side of the air classifier 1 is provided with vertical partitions 15 and L-shaped partitions 16. The vertical partitions 15 and L-shaped partitions 16 divide the inner cavity of the air classifier 1 into a superior seed chamber, a inferior seed chamber and a dust collection chamber from left to right. The top of the vertical partition 15 is provided with a curved partition 17. The bottom front end of the air classifier 1 is equipped with three hinged doors for removing the materials in the three chambers.

[0020] The left side of the air separator 1 is provided with a first air inlet pipe 18 and a second air inlet pipe 19 from top to bottom. The air inlet direction of the first air inlet pipe 18 is above the L-shaped partition 16, and the air inlet direction of the second air inlet pipe 19 is along the tangent of the curved partition 17. The ends of the first air inlet pipe 18 and the second air inlet pipe 19 are both connected to a blower box 20. Throttling valves are provided on the first air inlet pipe 18 and the second air inlet pipe 19, and the airflow rate and wind speed can be adjusted by the throttling valves.

[0021] The specific operation process of this utility model is as follows:

[0022] Workers pull the positioning rod 9 and handle 5 to insert the positioning rod 9 into the appropriate positioning hole 10, thereby adjusting the position of the baffle 4. The material gap formed between the bent edge 6 of the baffle 4 and the guide plate 7 allows all the sandalwood seeds to be screened to be poured into the feed pipe 2. The motor 12 is started to rotate the rotating rod 13, thereby realizing the reciprocating vibration of the guide plate 7 to ensure that the sandalwood seeds are fed evenly. The material layer of sandalwood seeds falling is relatively thin. Under the action of the blower 20, the first air inlet pipe 18 blows the lightest impurity dust along the upper part of the L-shaped partition 16 into the dust collection chamber on the far right. Under the blowing of the second air inlet pipe 19, the sandalwood seeds tumble on the curved partition 17. The lighter, less plump inferior seeds enter the inferior seed chamber upwards, while the plump, high-quality seeds enter the superior seed chamber below. After screening, the baffle 4 can be pulled to make all the seeds remaining on the baffle 4 fall off.
