Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of seed metering devices, and more specifically, to an adjustable precision seed metering device suitable for small-grained Chinese herbal medicine seeds. Background Technology

[0002] Traditional Chinese medicine (TCM) herbs are unique medicines used in TCM for the prevention and treatment of diseases. They are mainly composed of plant and mineral medicines. Because plant medicines make up the majority, TCM herbs are also called TCM herbs. When cultivating TCM herbs, small TCM herb seeds are usually placed in the soil using a seed truck, and then cultivated to grow.

[0003] During seeding, workers push the seeding cart forward, and the seeds of Chinese medicinal herbs are discharged from the seed outlet below the cart. However, the opening size of the existing small seeding carts is relatively uniform, and the number of seeds to be discharged into the soil varies greatly for different types of Chinese medicinal herbs. Some Chinese medicinal herbs only require a few seeds to be discharged, while others require more seeds to be discharged into a pit. Therefore, it is difficult to discharge the appropriate number of seeds according to the different types of Chinese medicinal herbs. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide an adjustable precision seed metering device suitable for small-grained Chinese herbal medicine seeds, which solves the technical problem that the discharge port of the seed metering vehicle in the prior art is relatively simple and it is difficult to discharge different numbers of seeds according to different types of Chinese herbal medicines.

[0005] According to one aspect, at least one embodiment of this disclosure provides an adjustable precision seed metering device suitable for small-grained Chinese herbal medicine seeds, including a seed metering cart with a feeding trough at its top, and further including a feeding cylinder, baffle plates, limiting components, and blocking components. The feeding cylinder is fixedly installed at the top of the seed metering cart by a support frame, and its bottom end is installed through and connected in the feeding trough. Three baffle plates are provided, and the three baffle plates are set at the bottom of the seed metering cart by a moving component. A feeding hole is opened at the center of each baffle plate, and a connecting plate is fixedly installed between the three baffle plates. Two limiting components are provided, both of which are set at the top of the seed metering cart for limiting and fixing the baffle plates. Each baffle plate is provided with a blocking component for blocking the feeding hole of the baffle plate.

[0006] Furthermore, the moving component includes a sliding rod, a sliding frame, and a pulling rod. The seeding cart has two through slots, and the sliding rod is fixedly installed in each of the two through slots. Two sliding frames are slidably installed on the sliding rod, and the other end of the sliding frame is fixedly installed on the side of the connecting plate. The pulling rod is fixedly installed between the two sliding frames.

[0007] Furthermore, the limiting component includes a limiting plate, a fixing plate, and a locking component. The limiting plate is fixedly installed on the side of the pulling rod, and a circular limiting groove is provided on the side of the limiting plate. Three fixing plates are provided, and all three limiting plates are fixedly installed on the top of the seed dispensing vehicle. The locking component is provided on each fixing plate.

[0008] Furthermore, the locking assembly includes a threaded rod, a locking block, and a handwheel. The threaded rod is threadedly mounted on each of the three fixing plates. The locking block is fixedly mounted on the side of the threaded rod, and the handwheel is coaxially connected to the threaded rod.

[0009] Furthermore, the material blocking assembly includes a blocking plate, a mounting plate, and an electric cylinder. The blocking plate is slidably mounted on the bottom end of the material blocking plate via a sliding assembly. The mounting plate is fixedly mounted on the side of the material blocking plate. The electric cylinder is mounted on the mounting plate, and the output end of the electric cylinder is fixedly connected to the side of the blocking plate.

[0010] Furthermore, the sliding assembly includes a support frame, a sliding rod, and a slider. There are two support frames, both of which are fixedly installed at the bottom end of the baffle plate. Two sliding rods are fixedly installed on each of the two support frames. There are two sliders, each of which is slidably installed on one of the two sliding rods. The sealing plate is fixedly installed between the two sliders.

[0011] In order to block the discharge hole of the baffle plate when no material is being discharged, the top of the sealing plate is further fitted to the bottom of the baffle plate.

[0012] In order to allow the seeds inside the feeding cylinder to fall onto the baffle plate, the area of ​​the baffle plate is further equal to the area of ​​the bottom end of the feeding cylinder.

[0013] In order to adjust the falling quantity of different Chinese herbal medicine seeds, the areas of the discharge holes of the three baffle plates are all different.

[0014] The beneficial effects of the embodiments disclosed herein are as follows:

[0015] 1. In this disclosure, when it is necessary to change the number of different Chinese herbal medicine seeds, the baffle plate can be moved to the feeding groove by the moving component, and then fixed by the limiting component. Thus, the number of different types of Chinese herbal medicines can be adjusted by moving the baffle plate with feeding holes of different areas to the feeding groove.

[0016] 2. In this disclosure, during seeding, the seeding frequency can be controlled by the baffle assembly, thereby creating a certain gap between the seeds. Furthermore, when seeding is not required, the baffle assembly can block the feeding hole of the baffle plate, preventing the seeds from falling.

[0017] In summary, this device, through the cooperation of the feeding cylinder, baffle plate, limiting component, and blocking component, can drive the movement of the three baffle plates, thereby adjusting the number and frequency of different Chinese herbal medicines to be fed.

[0033] like Figures 1-7As shown, an adjustable precision seed metering device for small-grained Chinese herbal medicine seeds according to an embodiment of this disclosure is illustrated. It includes a seed metering cart 1, with a feeding trough at its top. The cart also includes a feeding cylinder 2, baffle plates 3, a limiting component, and a blocking component. The feeding cylinder 2 is fixedly installed at the top of the seed metering cart 1 via a support frame 16, and its bottom end is connected and installed within the feeding trough. Three baffle plates 3 are provided, positioned at the bottom of the seed metering cart 1 via a moving component. A feeding hole is provided at the center of each baffle plate 3, and a connecting plate 4 is fixedly installed between the three baffle plates 3. Two limiting components are provided, both positioned at the top of the seed metering cart 1, for limiting and fixing the baffle plates 3. Each baffle plate 3 is equipped with a blocking component to block the feeding hole.

[0034] like Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, during sowing, the seed metering cart 1 is first pushed into the soil. Then, the baffle plate 3 is adjusted according to the required amount of medicinal herb seeds to be sown. The corresponding baffle plate 3 can be moved to the feeding trough by the moving component. Because the feeding holes of the three baffle plates 3 are different in area, if multiple seeds need to be sown in one soil area, the baffle plate 3 with the larger feeding hole is moved to the feeding trough. The moving component includes a sliding rod 5, a sliding frame 6, and a pulling rod 7. The seed metering cart 1 has two through slots, and a sliding rod 5 is fixedly installed in each of the two through slots. Two sliding frames 6 are slidably installed on the sliding rod 5, and the other end of the sliding frame 6 is fixedly installed on the side of the connecting plate 4. A pulling rod 7 is fixedly installed between the two sliding frames 6. Specifically, the operator holds the pulling rod 7, thereby driving the sliding frame 6 to move on the sliding rod 5. Under the action of the connecting plate 4, the three baffle plates 3 move synchronously. The position of the baffle plate 3 can be positioned and fixed by the limiting component, which includes a limiting plate 8, a fixing plate 9, and a locking component. The limiting plate 8 is fixedly installed on the side of the pulling rod 7, and a circular limiting groove is opened on the side of the limiting plate 8. Three fixing plates 9 are provided, and all three limiting plates 8 are fixedly installed on the top of the seed dispensing vehicle 1. Each fixing plate 9 is provided with a locking assembly, which includes a threaded rod 10, a locking block 11, and a handwheel 12. The threaded rod 10 is threadedly installed on each of the three fixing plates 9, the locking block 11 is fixedly installed on the side of the threaded rod 10, and the handwheel 12 is coaxially connected to the threaded rod 10. Specifically, because the area of ​​the baffle plate 3 is... With the bottom area of ​​the feeding cylinder 2 being consistent, the three baffle plates 3 move to the bottom of the feeding circular groove and correspond to each other. Then, the three fixed plates 9 correspond to the limiting plates 8 respectively, and the locking block 11 corresponds to the circular limiting groove of the limiting plate 8. It should be noted that the locking block 11 is set as a cylinder and the locking block 11 is adapted to the circular limiting groove. After the movement is completed, the handwheel 12 is turned to drive the threaded rod 10 to move forward on the fixed plate 9 and move the locking block 11 into the circular limiting groove of the limiting plate 8 for fixing.

[0035] like Figure 4 and Figure 5As shown, after fixing, the material-feeding hole of the baffle plate 3 is blocked and opened by the material-stopping assembly to allow material to be fed. The material-stopping assembly includes a sealing plate 13, a mounting plate 14, and an electric cylinder 15. The sealing plate 13 is slidably mounted on the bottom end of the baffle plate 3 via a sliding assembly. The mounting plate 14 is fixedly mounted on the side of the baffle plate 3. The electric cylinder 15 is mounted on the mounting plate 14, and the output end of the electric cylinder 15 is fixedly connected to the side of the sealing plate 13. The sliding assembly includes a support frame 16, a sliding rod 17, and a slider 18. Two support frames 16 are provided, and both support frames 16 are fixedly mounted on the bottom end of the baffle plate 3. Two sliding rods 17 are fixedly mounted on each of the two support frames 16. Two sliders 18 are provided, and the two sliders 18 are slidably mounted on the two sliding rods 17 respectively, and the sealing plate 16 is fixedly mounted on the baffle plate 3. The blocking plate 13 is fixedly installed between two sliders 18. Specifically, because the top of the blocking plate 13 is in contact with the bottom of the baffle plate 3, the electric cylinder 15 can be activated during material feeding. The output end of the electric cylinder 15 drives the blocking plate 13 to move on the sliding rods 17 on both sides through the sliders 18, thereby opening the feeding hole of the baffle plate 3, allowing a portion of the seeds to fall. After the seeds have fallen, the blocking plate 13 is moved into the feeding hole of the baffle plate 3 by the electric cylinder 15 to seal it. At this time, the operator pushes the seed metering cart 1 to the next position for seeding. It should be noted that the seed metering cart 1 is equipped with a controller that can control the extension and retraction time and distance of the output end of the electric cylinder 15, thereby controlling the closing and opening of the feeding hole of the baffle plate 3 by the blocking plate 13.

[0036] Working principle: When sowing, first push the seed metering cart 1 into the soil, then hold the pull rod 7 according to the amount of Chinese herbal medicine seeds to be sown, thereby driving the sliding frame 6 to move on the sliding rod 5. Under the drive of the connecting plate 4, the three baffle plates 3 move synchronously, moving the corresponding baffle plate 3 to the feeding groove. At this time, one of the fixing plates 9 corresponds to the limiting plate 8. Then, turn the handwheel 12 to drive the threaded rod 10 to move forward on the fixing plate 9, and move the locking block 11 into the circular limiting groove of the limiting plate 8 for fixing. Similarly, if the amount of seeds to be sown is small, the baffle plate 3 with the smaller feeding hole can be moved to the feeding groove, and then the corresponding fixing plate 9 and limiting plate 8 are fixed.

[0037] After the fixing is completed, the electric cylinder 15 is started. The output end of the electric cylinder 15 drives the sealing plate 13 to move on the sliding rods 17 on both sides via the slider 18, thereby opening the discharge hole of the baffle plate 3, so that a part of the seed falls down. After the seed falls down, the sealing plate 13 is moved into the discharge hole of the baffle plate 3 by the electric cylinder 15 to seal it. At this time, the worker pushes the seed metering cart 1 to the next position to plant the seed. Therefore, the seed metering cart 1 can be moved while planting the seed.

[0038] After the seeds of one type of Chinese herbal medicine have been sown, seeds of other types of Chinese herbal medicine can be used, and the positions of different baffles 3 at the feeding trough can be changed accordingly for subsequent sowing.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
