Description

Technical Field

[0001] The utility model relates to the technical field of agarwood processing, in particular to a screening mechanism for agarwood particles. Background Art

[0002] Agarwood is a medicinal material, which is the resin-containing wood of the white agarwood plant of the Thymelaeaceae family. It has the effects of promoting qi and relieving pain, warming the middle and stopping vomiting, and relieving asthma. It is often used for chest and abdominal distension and pain, stomach cold, vomiting and hiccups, kidney deficiency, qi reversal and shortness of breath. Agarwood granules are a form of agarwood processed into granules.

[0003] The existing patent document with publication number CN219424919U discloses a screening mechanism for agarwood particles, including a screening bin, a front tube hinge of the screening bin being hinged with two bin doors, a collecting bin being slidably connected to the bottom of the inner cavity of the screening bin, a screening assembly being arranged inside the screening bin, the screening assembly including a horizontal plate fixed to the left and right ends of the screening bin, a motor being fixed to the lower end of the horizontal plate, a disc being fixed to the output end of the motor, a connecting rod being fixed to the lower end of the disc, a push-pull rod being fixed to the outer surface of the connecting rod, a connecting plate being hingedly connected to the lower end of the push-pull rod, vertical plates being fixed to the opposite sides of the left and right connecting plates, and a plurality of pressure plates being fixed to the opposite sides of the two vertical plates.

[0004] Although the above equipment can screen agarwood particles of different sizes, after the screening is completed, the screening bins need to be taken out one by one manually in order to collect the agarwood particles; and once too much agarwood accumulates inside the screening bin, the agarwood particles will be spread on the surface of the screening bin, which will affect the screening efficiency. It is necessary to manually unload the material from time to time, affecting the continuity of the screening activity.

[0005] To this end, we propose a screening mechanism for agarwood particles to solve the above problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 5 A screening mechanism for agarwood particles includes a shell 1 and a particle inlet 2, which is embedded and installed on the shell 1. Agarwood particles can be introduced into the shell 1 through the particle inlet 2 to perform the screening activity of the agarwood particles.

[0028] Two mounting plates 7 are fixedly installed inside the housing 1, and vibration enhancement members 12 are fixedly installed on the mounting plates 7 at equal distances and uniformly, and a screening plate 8 is fixedly installed on the other end of the vibration enhancement members 12;

[0029] The vibration enhancement component 12 is composed of a passively retractable rod and a spring. When subjected to external force, the vibration enhancement component 12 can make the screening plate 8 vibrate, thereby performing the screening activity of the agarwood particles.

[0030] The mounting plate 7 and the screening plate 8 are both installed at an angle, so under the action of gravity, the agarwood particles will move to the lowest point, making it convenient for unified collection.

[0031] Blanking plates 9 are fixedly mounted on the two mounting plates 7, and the housing 1 is provided with two upper material outlets 10 and two lower material outlets 11 on both sides of the upper and lower blanking plates 9;

[0032] After screening, the agarwood particles will move to the drop plate 9, and then be discharged through the upper discharge port 10 and the lower discharge port 11. The collection activity is carried out while screening, which can ensure the continuity and durability of the screening activity.

[0033] The housing 1 is provided with a driving motor 4 , a ball screw 14 is fixedly mounted on the shaft output end of the driving motor 4 , a moving frame 15 is fixedly mounted on the nut portion of the ball screw 14 , and two driving plates 16 are fixedly mounted on the moving frame 15 .

[0034] The driving motor 4 is started to rotate the screw rod portion of the ball screw 14, thereby driving the nut to move on the screw rod. The movement of the nut portion of the ball screw 14 causes the moving frame 15 and the two driving plates 16 to move synchronously.

[0035] The two driving plates 16 are in direct contact with the corresponding blanking plates 9 .

[0036] When the moving frame 15 moves, the two driving plates 16 will move synchronously on the blanking plate 9, and then the driving plates 16 can push the agarwood particles accumulated on the blanking plate 9 to move, so that the agarwood particles can fall smoothly through the upper discharge port 10 and the lower discharge port 11 on both sides.

[0037] A slag collecting box 3 is slidably mounted on the bottom of the shell 1 .

[0038] The slag box 3 can be used to store agarwood particles that are small and have no use value. After the screening is completed, the operator can complete the cleaning activity by taking out the slag box 3 as a whole.

[0039] Two upper material delivery pipes 5 and two lower material delivery pipes 6 are mounted on the shell 1 . The upper material delivery pipe 5 corresponds to the upper material outlet 10 , and the lower material delivery pipe 6 corresponds to the lower material outlet 11 .

[0040] Agarwood particles of different particle sizes are transported through the upper conveying pipe 5 and the lower conveying pipe 6 respectively. The larger particles are transported through the upper conveying pipe 5, and the smaller particles are transported through the lower conveying pipe 6. A container is set at the bottom to receive the agarwood particles to complete the collection activity.

[0041] A lifting plate 18 is slidably installed inside the shell 1 , and the lifting plate 18 can directly contact the two screening plates 8 at the same time.

[0042] By moving the lifting plate 18 up and down, the lifting plate 18 can be made to intermittently contact the two screening plates 8, thereby driving the screening plates 8 to vibrate, thereby ensuring the screening effect.

[0043] The ball screw 14 is provided with a synchronization component 13 , a special-shaped block 17 is fixedly mounted on the synchronization component 13 , and a groove adapted to the special-shaped block 17 is formed on the lifting plate 18 .

[0044] The synchronous component 13 can be a conveyor belt. When the screw part of the ball screw 14 rotates, the special-shaped block 17 can be rotated. The rotation of the special-shaped block 17 can make the lifting plate 18 move up and down, thereby completing the screening driving activity.

[0045] The meshes of the upper and lower screening plates 8 are of different sizes, and the mesh diameter of the upper screening plate 8 is larger than that of the bottom screening plate 8 .

[0046] The working process of the utility model is to introduce agarwood particles into the shell 1 through the particle inlet 2, and then perform the screening activity of the agarwood particles.

[0047] The agarwood particles will first fall onto the upper screening plate 8 for screening, and the particles with smaller particle sizes will fall onto the lower screening plate 8, completing the screening activity.

[0048] Start the driving motor 4 to rotate the screw part of the ball screw 14. When the screw part of the ball screw 14 rotates, the special-shaped block 17 can be rotated. The rotation of the special-shaped block 17 can make the lifting plate 18 move up and down, so that the lifting plate 18 can intermittently contact the two screening plates 8, so that the vibration amplitude of the screening plate 8 is larger, further ensuring the screening effect.

[0049] The mounting plate 7 and the screening plate 8 are both installed at an angle, so under the action of gravity, the agarwood particles will move to the lowest point, that is, the agarwood particles after screening will move to the blanking plate 9.

[0050] The movement of the nut part of the ball screw 14 causes the movable frame 15 and the two driving plates 16 to move synchronously, and the two driving plates 16 will move synchronously on the blanking plate 9, so that the driving plate 16 can push the agarwood particles accumulated on the blanking plate 9 to move, so that the agarwood particles can smoothly fall through the upper discharge port 10 and the lower discharge port 11 on both sides.

[0051] Agarwood particles of different particle sizes are transported through the upper conveying pipe 5 and the lower conveying pipe 6 respectively. The larger particles are transported through the upper conveying pipe 5, and the smaller particles are transported through the lower conveying pipe 6. A container is set at the bottom to receive the agarwood particles to complete the collection activity.
