Description

Technical Field

[0001] This utility model relates to the field of seeder technology, and more specifically, to a seed guiding device for a Chinese medicinal herb seeder with adjustable row spacing. Background Technology

[0002] As an important part of my country's traditional medicine, the scale of Chinese medicinal herbs cultivation continues to expand with the growth of market demand. In the process of cultivating Chinese medicinal herbs, the sowing stage is crucial. Appropriate row spacing not only ensures that the plants have sufficient growing space to receive sufficient sunlight, nutrients, and water, but also facilitates subsequent field management, such as weeding, fertilization, and irrigation.

[0003] Currently, most of the seed guiding devices equipped with Chinese medicinal herb planters on the market adopt a fixed row spacing design. This fixed row spacing seed guiding device cannot flexibly adjust the row spacing according to the growth characteristics of different Chinese medicinal herb varieties, soil fertility, and planting environment. For example, for Chinese medicinal herb varieties with vigorous plant growth and well-developed root systems, a fixed narrow row spacing will lead to insufficient plant growth space, causing them to compete for resources and affecting yield and quality. On the other hand, for some Chinese medicinal herbs with smaller row spacing requirements, an excessively wide row spacing will result in a waste of land resources.

[0004] Some seed guiding devices with simple row spacing adjustment functions have complex adjustment structures and are cumbersome to operate, requiring a lot of time and manpower for adjustment, which causes inconvenience to users. In view of this, we propose a seed guiding device for Chinese medicinal herb seeders with adjustable row spacing. Utility Model Content

[0005] The purpose of this invention is to provide a seed guiding device for a Chinese medicinal herb planter with adjustable row spacing, so as to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable row spacing herbal medicine planter seed guiding device includes a crossbeam, on which a seed storage cylinder is mounted. A discharge hopper is fixedly installed at the bottom of the seed storage cylinder. The discharge hopper has multiple discharge channels with their bottom ends connected to the outside. Multiple vertical pipes connected to the corresponding discharge channels are fixedly installed at the bottom of the discharge hopper. A discharge hopper is located at the bottom of the vertical pipes at a side position. The discharge hopper moves left and right along a rectangular rod to adjust the discharge position. The vertical pipes are equipped with feeding blades for controlling the discharge amount. The multiple feeding blades are driven by a servo motor and a long shaft.

[0008] Preferably, the seed storage cylinder has a storage chamber inside, and the inner wall of the discharge hopper is inclined downward at 45°~60°.

[0009] This setting makes the seed fall more smoothly.

[0010] Preferably, an adding tube is fixedly installed on the top of the seed storage cylinder, and a sealing cap is threaded onto the adding tube.

[0011] Preferably, a support leg is fixedly installed at the bottom of the seed storage cylinder, and a support base is fixedly installed at the bottom of the support leg, with the support base fixedly installed on the crossbeam.

[0012] Preferably, a central tube is fixedly installed at the bottom end of the vertical tube located at the center, and the central tube is arranged vertically.

[0013] Preferably, the feeding blade is fixedly mounted on the long shaft, and the end of the long shaft is fixedly mounted on the output shaft of the servo motor;

[0014] This setting utilizes a servo motor to drive the long shaft and the feeding blades to rotate, thereby controlling the amount of material fed.

[0015] Preferably, the plane of the inner wall of the unloading hopper is inclined downward at 30° to 60°, and the inner wall of the unloading hopper is provided with a smooth non-stick layer.

[0016] Preferably, a rectangular sliding sleeve is fixedly installed at the bottom of the unloading hopper. The rectangular sliding sleeve is fitted onto the rectangular rod and slidably connected to the rectangular rod. The rectangular sliding sleeve and the rectangular rod are fixed together by fastening bolts.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model achieves flexible adjustment of different discharge positions and discharge amounts by setting up a discharge hopper with multiple discharge channels, a discharge hopper that can move left and right, and a feeding blade driven by a servo motor. Operators can adjust the position of the discharge hopper to change the sowing row spacing according to the variety of Chinese medicinal materials and planting needs. At the same time, the rotation of the feeding blade is precisely controlled by the servo motor to accurately control the discharge amount. This not only avoids the problem of unreasonable growth space or land waste caused by fixed row spacing, but also achieves precise sowing, improves planting quality and land utilization.

[0019] 2. This utility model achieves smooth seed transport from the storage cylinder to the discharge hopper by setting a storage chamber inside the seed storage cylinder and tilting the inner wall of the discharge hopper downwards, while also providing a smooth, non-stick layer on the inner wall of the discharge hopper. The tilted discharge hopper and the smooth inner wall of the discharge hopper reduce resistance during seed descent, prevent seed blockage, ensure the continuity of the sowing process, reduce the frequency of manual cleaning and maintenance, and improve sowing efficiency.

[0020] 3. This utility model achieves structural stability and ease of use by setting an adding tube and a sealing cap at the top of the seed storage cylinder, installing support legs and a support base at the bottom, and using a rectangular sliding sleeve and fastening bolts to connect and fix the unloading hopper to the rectangular rod. The adding tube facilitates seed addition, and the sealing cap prevents the seeds from getting damp. The stable support structure ensures stable operation of the device. The sliding connection and fixing method of the unloading hopper allows operators to quickly adjust the unloading position. The entire device is easy to operate, reduces labor costs and operational difficulty, and enhances practicality. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-3 This utility model provides a technical solution: an adjustable row spacing seed guiding device for Chinese medicinal herbs, including a crossbeam 1 installed on the seeding vehicle, and a seed storage cylinder 10 provided on the crossbeam 1, so that the crossbeam 1 provides a stable installation platform for the entire seed guiding device, ensuring the stability of each component during operation and enabling the device to operate reliably.

[0030] Specifically, a discharge hopper 14 is fixedly installed at the bottom of the seed storage cylinder 10. The discharge hopper 14 is provided with multiple discharge channels 141 whose bottom ends are connected to the outside. Multiple vertical pipes 15 connected to the corresponding discharge channels 141 are fixedly installed at the bottom of the discharge hopper 14. The seed storage cylinder 10 is provided with a storage chamber 11, which allows the seed storage cylinder 10 to store a large number of seeds. The discharge hopper 14 distributes the seeds evenly into the corresponding vertical pipes 15 through multiple discharge channels 141, realizing simultaneous seed supply through multiple channels, and providing a sufficient and stable seed source for subsequent sowing operations.

[0031] Specifically, a discharge hopper 20 is provided at the bottom of the vertical pipe 15 located on the side. The discharge hopper 20 moves left and right along the rectangular rod 2 to adjust the discharge position, thereby adjusting the sowing spacing. The rectangular rod 2 is also fixedly installed on the sowing vehicle. The vertical pipe 15 is provided with a feeding blade 31 for controlling the discharge amount. Multiple feeding blades 31 are driven by a servo motor 3 and a long shaft 30, allowing the operator to flexibly adjust the position of the discharge hopper 20 according to the sowing needs, thereby changing the row spacing and improving the adaptability of the seed guiding device to different planting layouts, meeting the diverse sowing needs of Chinese medicinal materials.

[0032] In this embodiment, the inner wall of the discharge hopper 14 is inclined downward at 45°~60°, which allows the seeds to slide more smoothly from the seed storage cylinder 10 to the discharge channel 141 under the action of gravity, reducing the accumulation and blockage of seeds in the discharge hopper 14, ensuring the continuity and stability of seed delivery, and improving sowing efficiency.

[0033] like Figure 1 As shown, an adding tube 12 is fixedly installed on the top of the seed storage cylinder 10. A sealing cap 121 is threaded onto the adding tube 12, allowing the operator to easily add seeds to the seed storage cylinder 10 through the adding tube 12. The sealing cap 121 can effectively prevent the seeds from getting damp or contaminated, ensuring seed quality, and also preventing seeds from spilling out from the adding tube 12 during the sowing process.

[0034] like Figure 1 As shown, a support leg 13 is fixedly installed at the bottom of the seed storage cylinder 10, and a support base 131 is fixedly installed at the bottom of the support leg 13. The support base 131 is fixedly installed on the crossbeam 1, so that the support leg 13 and the support base 131 together form a stable support structure, which enhances the stability of the seed storage cylinder 10 and prevents it from shaking or shifting due to seed weight or mechanical vibration during sowing, thus ensuring the safety of seed storage and transportation.

[0035] like Figure 1As shown, a central tube 16 is fixedly installed at the bottom of the vertical tube 15 located at the center position. The central tube 16 is set vertically so that the seeds in the middle position can fall down along the central tube 16.

[0036] like Figure 1 and Figure 2 As shown, the feeding blade 31 is fixedly mounted on the long shaft 30, and the end of the long shaft 30 is fixedly mounted on the output shaft of the servo motor 3, so that the servo motor 3 can precisely control the rotation speed of the long shaft 30, thereby driving the feeding blade 31 to rotate at a suitable speed. By adjusting the rotation speed and angle of the feeding blade 31, the precise control of the unloading amount is achieved, ensuring the uniformity of the sowing density and improving the sowing quality.

[0037] It is worth noting that the inner wall of the unloading hopper 20 is inclined downward at a angle of 30° to 60°. A smooth non-stick layer 201 is provided on the inner wall of the unloading hopper 20, which allows the seeds in the unloading hopper 20 to slide down quickly and smoothly under the action of gravity. The smooth non-stick layer 201 further reduces the friction and adhesion between the seeds and the inner wall of the unloading hopper 20, prevents seed residue, ensures clean and thorough unloading, and also facilitates the cleaning and maintenance of the unloading hopper 20.

[0038] like Figure 1 As shown, a rectangular sliding sleeve 21 is fixedly installed at the bottom of the unloading hopper 20. The rectangular sliding sleeve 21 is fitted onto the rectangular rod 2 and slidably connected to the rectangular rod 2. The rectangular sliding sleeve 21 and the rectangular rod 2 are fixed together by fastening bolts 22, so that the unloading hopper 20 can slide flexibly on the rectangular rod 2. This allows the operator to adjust the position of the unloading hopper 20 as needed. After adjustment, the unloading hopper 20 can be firmly fixed by fastening bolts 22 to ensure that the unloading hopper 20 will not shift during the sowing process and to ensure the accuracy of the sowing row spacing.

[0039] Finally, it should be noted that the servo motor 3, the corresponding servo system, and the external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the adapted controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0040] When using the adjustable row spacing herbal medicine planter seed guiding device of this utility model, rotate the fastening bolt 22, loosen the rectangular sliding sleeve 21, move the unloading hopper 20 left and right along the rectangular rod 2 according to the planting needs, and after adjusting the sowing spacing, tighten the fastening bolt 22 to fix it.

[0041] Open the sealing cap 121, pour the Chinese medicinal herb seeds into the storage chamber 11 of the seed storage cylinder 10 through the adding tube 12, tighten the sealing cap 121, start the sowing vehicle, and drive to the field to be sown. At this time, under the action of gravity, the seeds pass through the inner wall of the discharge hopper 14 and enter the vertical pipe 15 evenly through the discharge channel 141.

[0042] According to the seeding requirements, the servo motor 3 drives the long shaft 30 and the feeding blade 31 to rotate at a suitable speed to precisely control the unloading amount. Seeds fall from the vertical pipe 15, side seeds are sown through the unloading hopper 20, and middle seeds fall through the central pipe 16. The inner wall of the unloading hopper 20 is inclined and has a smooth non-stick layer 201 to ensure that the seeds are unloaded quickly and cleanly, thus completing the seeding operation.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
