Abstract

This utility model discloses an Angelica sinensis roller seeder, relating to the field of Angelica sinensis planting technology. It includes a sowing component comprising a seed storage trough, which is a hollow cavity structure used to store Angelica sinensis seeds. An adjustment component is installed inside the cavity; the adjustment component includes a support shaft located at the lower end of the seed storage trough. This Angelica sinensis roller seeder, when a small amount of Angelica sinensis seeds are added to the seed storage trough, drives a screw to move a support rod horizontally. The support rod, via a rotating shaft, drives a fixed block to slide along the outside of a push plate. The fixed block then pushes the push plate to rotate along the support shaft, causing the push plate to push the Angelica sinensis seeds closer to the outside of the sowing roller. This ensures that even with a small amount of seeds, the sowing roller can still absorb and sow the seeds into the seedling tray.

Description

Technical Field

[0001] This utility model relates to the field of Angelica sinensis planting technology, and in particular to an Angelica sinensis roller seeder. Background Technology

[0002] Angelica sinensis is a perennial herb belonging to the genus Angelica in the family Apiaceae. Its dried root is a commonly used blood-tonifying and blood-activating medicine in Traditional Chinese Medicine, and is known as the "holy medicine of blood." Sowing is a crucial step in the cultivation of Angelica sinensis, directly affecting the germination rate, quality, and yield of the medicinal material. When sowing Angelica sinensis, a roller seeder is usually used to sow the seeds into seedling trays.

[0003] Currently, when a roller seeder sows angelica seeds into the seedling tray, a relatively large amount of seeds needs to be put into the seed storage trough. When there are few angelica seeds in the seed storage trough, the sowing roller of the roller seeder has difficulty adsorbing the angelica seeds in the seed storage trough and sowing them into the seed storage trough. Utility Model Content

[0004] This utility model discloses an Angelica sinensis roller seeder, which aims to solve the technical problem that when the current roller seeder sows Angelica sinensis seeds into the seedling tray, a large number of seeds need to be put into the seed storage trough of the roller seeder. When there are few Angelica sinensis seeds in the seed storage trough, the sowing roller of the roller seeder is unable to absorb the Angelica sinensis seeds in the seed storage trough and sow them into the seed storage trough.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A angelica roller seeder includes a seeding assembly, which includes a seed storage trough. The seed storage trough is a hollow cavity structure used to store angelica seeds. An adjustment component is provided inside the cavity.

[0007] The adjustment assembly includes a support shaft located at the lower end of the seed storage trough. A push plate is provided on the outer surface of the support shaft, and a fixing block is provided on the outer side of the push plate. The fixing block is U-shaped, and a rotating shaft is provided inside the fixing block. A support rod is provided on the outer surface of the rotating shaft, and a screw is provided at the end of the support rod away from the rotating shaft. A fixing nut is provided on the outer surface of the screw. A support block is also provided at the upper end of the outer side of the seed storage trough.

[0008] In a preferred embodiment, the sowing assembly further includes a base, a conveyor belt at the upper end of the base, a fixing frame at the upper end of the conveyor belt, a sowing roller inside the fixing frame, a seed storage trough at the lower end of the fixing frame, and the sowing roller located inside the seed storage trough.

[0009] In a preferred embodiment, the end of the screw away from the support rod extends outward through the seed storage tank and the support block, the support block having a threaded structure relative to the screw.

[0010] In a preferred embodiment, the push plate is located inside the seed storage trough on one side, and the support rod has a hollow structure that opens relative to the rotation axis.

[0011] In a preferred embodiment, the upper end of the fixed frame is further provided with a toggle assembly. The toggle assembly includes a support frame disposed on one side of the upper end of the fixed frame. A reciprocating motor is disposed on the outside of the support frame. A lead screw is disposed on the output shaft of the reciprocating motor. The lead screw is disposed inside the support frame and one end of the lead screw extends outward through the support frame. A guide rod is also disposed inside the support frame. Movable rods are disposed on both sides of the outer surface of the lead screw. A toggle rake is disposed at the bottom end of the movable rod.

[0012] In a preferred embodiment, the outer surface of the lead screw is provided with opposite thread structures on both sides, and the movable rod is provided in two sets, which are symmetrically distributed along the center line of the lead screw.

[0013] In a preferred embodiment, the lower end of the movable rod is disposed on the outer surface of the guide rod, and the movable rod and the agitator are located on the outer side of the seeding drum.

[0014] As can be seen from the above, the Angelica sinensis roller seeder provided by this utility model has the following technical effects.

[0015] Firstly, when a small amount of Angelica seeds are put into the seed storage tank, the screw is pushed to move the support rod horizontally. The support rod drives the fixed block to slide along the outside of the push plate through the rotating shaft. The fixed block pushes the push plate to rotate along the support shaft, so that the push plate pushes the Angelica seeds to the outside of the sowing drum. This allows the sowing drum to still absorb and sow the Angelica seeds into the seedling tray even when there are few seeds.

[0016] Secondly, when there are Angelica seeds in the seed storage trough, in order to ensure that the number of Angelica seeds on both sides of the seed storage trough is the same, a reciprocating motor drives the lead screw to rotate. The lead screw converts the circular motion into linear motion, so that the movable rod moves horizontally along the guide rod. The movement of the movable rod drives the agitator to move horizontally. The agitator moves the Angelica seeds in the seed storage trough, so that the Angelica seeds in the seed storage trough are evenly distributed. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0024] Reference Figure 1 , Figure 2 , Figure 3 A type of angelica roller seeder includes a sowing component, which includes a seed storage trough 14. The seed storage trough 14 is a hollow cavity structure used to store angelica seeds. An adjustment component is provided inside the cavity. The adjustment component includes a support shaft 21 located at the lower end of the seed storage trough 14. A push plate 22 is provided on the outer surface of the support shaft 21. A fixing block 23 is provided on the outer side of the push plate 22. The fixing block 23 is U-shaped. A rotating shaft 24 is provided inside the fixing block 23. A support rod 25 is provided on the outer surface of the rotating shaft 24. A screw 26 is provided at the end of the support rod 25 away from the rotating shaft 24. A fixing nut 28 is provided on the outer surface of the screw 26. A support block 27 is also provided at the upper outer end of the seed storage trough 14.

[0025] In this embodiment, by adjusting the component, the push plate 22 can rotate inside the seed storage tank 14. During the rotation of the push plate 22, the angelica seeds in the seed storage tank 14 can be pushed by the push plate 22 to the outside of the sowing roller 15. Thus, when a small number of angelica seeds are placed, the sowing roller 15 can still effectively adsorb the angelica seeds.

[0026] Reference Figure 3 In a preferred embodiment, the sowing assembly further includes a base 11, a conveyor belt 12 is provided at the upper end of the base 11, a fixing frame 13 is provided at the upper end of the conveyor belt 12, a sowing roller 15 is provided inside the fixing frame 13, a seed storage trough 14 is provided at the lower end inside the fixing frame 13, the sowing roller 15 is located inside the seed storage trough 14, one end of the screw 26 away from the support rod 25 extends outward through the seed storage trough 14 and the support block 27, the support block 27 has a threaded structure relative to the screw 26, the push plate 22 is located on one side inside the seed storage trough 14, and the support rod 25 has a hollow structure relative to the rotation shaft 24.

[0027] In this embodiment, the seedling tray (not shown in the figure) is transported by the conveyor belt 12. The seedling tray can be moved to the bottom of the sowing roller 15. The sowing roller 15 rolls to absorb the Angelica seeds from the seed storage tank 14 and sow them into the seedling tray.

[0028] Reference Figure 4 In a preferred embodiment, the upper end of the fixed frame 13 is further provided with a toggle assembly. The toggle assembly includes a support frame 31 disposed on one side of the upper end of the fixed frame 13, a reciprocating motor 32 disposed on the outside of the support frame 31, a lead screw 33 disposed on the output shaft of the reciprocating motor 32, the lead screw 33 being disposed inside the support frame 31 and one end of the lead screw 33 extending outward through the support frame 31, a guide rod 34 being disposed inside the support frame 31, movable rods 35 being disposed on both sides of the outer surface of the lead screw 33, a toggle rake 36 being disposed at the bottom end of the movable rod 35, and opposite thread structures being opened on both sides of the outer surface of the lead screw 33. Two sets of movable rods 35 are disposed, and the two sets of movable rods 35 are symmetrically distributed along the center line of the lead screw 33. The lower end of the movable rod 35 is disposed on the outer surface of the guide rod 34, and the movable rod 35 and the toggle rake 36 are located outside the seeding roller 15.

[0029] In this embodiment, the agitator component drives the agitator rake 36 to move back and forth inside the seed storage trough 14 via the movable rod 35, so that the Angelica seeds in the seed storage trough 14 can be agitated horizontally back and forth under the action of the agitator rake 36. When a large number of Angelica seeds can move to the position of a smaller number of Angelica seeds, the Angelica seeds can be evenly spread inside the seed storage trough 14.

[0030] Working principle: When sowing Angelica seeds into the seedling tray, the seedling tray (not shown in the figure) is placed on the upper end of the conveyor belt 12 and transported to the area below the sowing drum 15. Then, the Angelica seeds are placed into the seed storage trough 14. The sowing drum 15 rolls, adsorbing and sowing the Angelica seeds into the seedling tray. When the number of Angelica seeds in the seed storage trough 14 is small, the operator pushes the screw 26, which moves inwards towards the seed storage trough 14. The movement of the screw 26 moves the support rod 25, which, through the rotating shaft 24, drives the fixed block 23 to slide along the outside of the push plate 22. This causes the push plate 22 to rotate around the support shaft 21 towards the sowing drum 15. During this rotation, the push plate 22 sows the Angelica seeds into the seedling tray. The roller 15 is pushed in the direction of the seeding roller, so that the seeding roller 15 can still adsorb and sow the angelica seeds into the seedling tray. At the same time, in order to avoid uneven distribution of angelica seeds in the seed storage trough 14, which would cause uneven adsorption and sowing of angelica seeds by the seeding roller 15, the reciprocating motor 32 is started. The reciprocating motor 32 drives the lead screw 33 to rotate. The rotation of the lead screw 33 converts the circular motion into linear motion. The lead screw 33 drives the two sets of movable rods 35 to move in opposite directions. The movable rods 35 then drive the agitator 36 to move in opposite directions. During the movement of the agitator 36, the angelica seeds are agitated, so that the more angelica seeds are moved to the position of the fewer angelica seeds, so that the angelica seeds in the seed storage trough 14 are evenly distributed inside the seed storage trough 14.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
