Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a regionalized quantitative seedling planting device for planting Chinese medicinal herbs. Background Technology

[0002] As an important sector of agriculture, the planting process of Chinese medicinal herbs has a crucial impact on their growth quality and yield. Traditionally, planting relies heavily on manual labor, which is not only inefficient but also prone to inconsistencies in planting depth and spacing due to human error, thus affecting the growth environment. To improve planting efficiency and consistency, some mechanized planting devices have emerged on the market. However, these devices are mostly single-function and difficult to adapt to the needs of different regional planting areas. Furthermore, existing planting equipment has limitations in quantitative control, often affecting the overall planting effect due to uneven sowing rates or deviations in planting position. Since the planting of Chinese medicinal herbs typically requires adjustments based on terrain and soil conditions, the lack of flexibility and precision in existing devices limits their practical application. Utility Model Content

[0003] The purpose of this utility model is to provide a regionalized quantitative seedling planting device for planting Chinese medicinal herbs, which solves the problems mentioned in the background art.

[0004] This utility model is implemented as follows: a regionalized quantitative seedling planting device for Chinese medicinal herbs includes a frame, a drive box on one side of the top of the frame, and a seedling box with an open top and bottom. A support plate is fixedly installed on the other side of the top of the frame. A series of spaced slide rails are fixed between the drive box and the support plate. The seedling box is located between the slide rails. The output end of the drive box is a crank-connecting rod mechanism connected to the seedling box. The drive box drives the seedling box to reciprocate on the slide rails via the crank-connecting rod mechanism. An inclined guide trough is fixedly connected to the frame and is located at the bottom of the seedling box. A seedling separating component is also included. The seedling separating component is located inside the seedling box and includes a separating disc rotatably installed inside the seedling box. The separating disc has multiple evenly arranged seedlings. The seedling separating hole and the seedling separating assembly also include two arc-shaped baffles and two inclined baffles. The two arc-shaped baffles are spaced apart along the axial direction of the seedling separating tray and fixedly connected to the inner walls of both sides of the seedling box. The two inclined baffles are spaced apart along the radial direction of the seedling separating tray and fixedly connected to the inner walls of both sides of the seedling box. The height of the arc-shaped baffles and the inclined baffles is greater than the height of the axis of the seedling separating tray. The arc-shaped baffles and the inclined baffles are matched with the surface of the seedling separating tray. The arc-shaped baffles, the inclined baffles, the top surface of the seedling separating tray and the inner wall of the seedling box form a seedling storage compartment. The seedling box is provided with main rollers on both sides that match two slide rails. The main rollers are provided with a pawl structure with a one-way rotation function. The main rollers and the seedling separating tray are connected by a reduction gear fixedly set on the outer surface of the seedling box.

[0005] Preferably, an auxiliary box is fixedly connected to the side of the seedling box away from the drive box, and auxiliary rollers that cooperate with the slide rail frame are rotatably arranged on both sides of the auxiliary box. The auxiliary box, auxiliary rollers, main rollers and seedling tray are all in the same plane.

[0006] Preferably, a rectangular opening is provided at the junction of the seedling box and the auxiliary box. A vertically arranged guide column is fixedly connected inside the auxiliary box, and a horizontally arranged slide rod is slidably connected to the guide column. A strip scraper is fixedly connected to one end of the slide rod facing the rectangular opening, and a cleaning brush is provided on the strip scraper. A double-ended bracket is connected to the other end of the slide rod, and pins are fixedly connected to both ends of the double-ended bracket. Turntables connected to auxiliary rollers are provided on both sides of the auxiliary box. Elliptical grooves that cooperate with the pins are provided on the turntables. When the seedling box moves back and forth, the cleaning brush at one end of the slide rod moves back and forth through the cooperation of the turntable and the pins, so that it contacts the surface of the seedling tray.

[0007] Preferably, an elastic sealing layer is fixedly connected to the slide rod, and the elastic sealing layer is sealed to the inner wall of the auxiliary box. The elastic sealing layer is located between the guide column and the strip scraper. The elastic sealing layer isolates the internal space of the auxiliary box into a closed chamber, and the double-end bracket and turntable are both located in the closed chamber.

[0008] Preferably, airflow channels are provided inside the strip scraper and the slide bar. Multiple airflow outlets are provided on the side of the strip scraper located on the cleaning brush. An exhaust pipe connected to the airflow channels is fixedly connected to the double-end bracket. An air inlet pipe is fixedly provided on the top of the auxiliary box. One-way valves are provided on both the exhaust pipe and the air inlet pipe. A dust cover is fixedly connected to the top of the air inlet pipe.

[0009] Preferably, a detection box is fixedly connected to one side of the seedling box opposite to the rectangular opening. An image acquisition module is installed inside the detection box. A transparent observation window is fixedly installed at the joint between the detection box and the seedling box. Electromagnetic clutches for driving the auxiliary rollers and turntables are fixedly connected to both sides of the auxiliary box.

[0010] Preferably, the seedling box has a seedling outlet door on one side of the seedling storage compartment that can be closed or opened.

[0011] The regionalized quantitative seedling planting device for Chinese medicinal herbs provided by this utility model works on the following principle: The drive box moves the planting box back and forth on the slide rail frame via a crank-connecting rod mechanism. Simultaneously, the pawl structure on the main roller cooperates with the reduction mechanism to make the seedling tray rotate slowly within the planting box. During rotation, the seedling holes on the seedling tray pass through different areas of the seedling storage chamber sequentially, completing the seedling separation operation. The design of the arc-shaped baffle and the inclined baffle ensures that the medicinal herbs on the surface of the seedling tray are effectively guided into the seedling holes, preventing accumulation or leakage. The cleaning brush inside the auxiliary box moves back and forth through the cooperation of the turntable and pins, cleaning residues from the surface of the seedling tray and keeping the seedling holes unobstructed. The elastic sealing layer isolates the internal space of the auxiliary box into a closed chamber, preventing dust from entering and affecting the cleaning effect. The airflow channels in the strip scraper and the slide rod form an airflow circulation through the air inlet and exhaust pipes, further enhancing the cleaning effect. The image acquisition module inside the detection box monitors the working status of the seedling tray in real time through a transparent observation window, and combined with the control of the electromagnetic clutch, it achieves precise regional quantitative seedling planting.

[0012] The technical advantages of this invention are reflected in the following aspects: First, the automation and high efficiency of the seedling planting process are achieved through the coordination of the drive housing, crank-connecting rod mechanism, slide rail frame, and seedling tray, solving the problem of low efficiency in traditional manual seedling planting. Second, the seedling holes on the seedling tray, combined with the guiding effect of arc-shaped baffles and inclined baffles, ensure the uniform distribution and precise placement of medicinal materials, solving the problem of insufficient quantitative control in existing devices. Third, the dual cleaning mechanism of cleaning brushes and airflow channels effectively avoids the clogging of seedling holes, reduces the frequency of downtime for cleaning, and improves the continuous operation capability of the device. Finally, the introduction of an image acquisition module and an electromagnetic clutch enhances the intelligence level of the device, enabling it to flexibly adjust seedling planting parameters according to actual needs and meet the requirements of different regional planting. In summary, this invention, through the organic combination of mechanical structure and intelligent control, not only improves seedling planting efficiency but also significantly enhances the accuracy and adaptability of seedling planting, providing reliable technical support for the cultivation of Chinese medicinal materials.

[0018] This utility model provides a regionalized quantitative seedling planting device for planting Chinese medicinal herbs, the structure of which is as follows: Figures 1 to 3As shown in the figure, the device includes a frame 1, a seedling box 2, a drive box 3, a slide rail frame 4, a seedling tray 5, an arc-shaped baffle 6, an inclined baffle 7, a cleaning brush 8, a detection box 9, a transparent observation window 10, an electromagnetic clutch 11, an air inlet pipe 12, an exhaust pipe 13, an auxiliary box 14, a strip scraper 15, a slide rod 16, and an elastic sealing layer 17. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] The frame 1 serves as the main support for the entire device. A drive housing 3 is fixedly mounted on one side of its top, and a support plate is fixedly connected to the other side. Two spaced-apart slide rails 4 are bolted between the drive housing 3 and the support plate. The slide rails 4 are arranged in parallel, and their inner sides have guide grooves for engaging with the main rollers on the seedling box 2 to achieve reciprocating movement. The seedling box 2 is located between the two slide rails 4, with open tops and bottoms. Main rollers are installed on the outer walls of both sides of the seedling box 2, engaging with the guide grooves of the slide rails 4 to allow the seedling box 2 to reciprocate horizontally along the slide rails 4. The main rollers are equipped with pawl structures, which have a unidirectional rotation function, converting the rotational motion of the main rollers into the rotation of the seedling tray 5.

[0020] The output end of the drive housing 3 is connected to the seedling box 2 via a crank-connecting rod mechanism. This mechanism includes a crank and a connecting rod. One end of the crank is fixedly connected to the output shaft of the drive housing 3, and the other end is hinged to the connecting rod via a pin. The other end of the connecting rod is hinged to the side wall of the seedling box 2 via a pin. When the drive housing 3 starts, its output shaft drives the crank to rotate, and the crank, through the connecting rod, pulls the seedling box 2 to reciprocate on the slide rail frame 4. The reciprocating distance of the seedling box 2 is determined by the length of the crank, thus ensuring the accuracy of the seedling position.

[0021] The seedling box 2 is equipped with a seedling separating assembly, which includes a separating tray 5, an arc-shaped baffle 6, and an inclined baffle 7. The separating tray 5 is rotatably mounted inside the seedling box 2 via bearings. The surface of the separating tray 5 has multiple evenly arranged separating holes, the diameter and depth of which are designed according to the size of the medicinal herb seedlings to ensure that each hole can accommodate one seedling. The arc-shaped baffle 6 and the inclined baffle 7 are fixed to the inner walls of both sides of the seedling box 2. The arc-shaped baffle 6 is spaced along the axial direction of the separating tray 5, and the inclined baffle 7 is spaced along the radial direction of the separating tray 5. The height of both the arc-shaped baffle 6 and the inclined baffle 7 is greater than the height of the axis of the separating tray 5, and both fit into the surface of the separating tray 5. The arc-shaped baffle 6 and the inclined baffle 7, together with the top surface of the separating tray 5 and the inner wall of the seedling box 2, form a seedling storage chamber for storing the medicinal herb seedlings to be planted. The seedling storage chamber has a seedling outlet door on one side, which can be opened or closed as needed to replenish seedlings or clean up residue.

[0022] The main roller of the seedling box 2 is connected to the seedling tray 5 via a reduction gear mechanism, which is fixedly mounted on the outer surface of the seedling box 2. The reduction gear mechanism includes a gear set and a drive shaft. The rotational motion of the main roller is transmitted to the drive shaft via the gear set, and the drive shaft then transmits power to the seedling tray 5, thereby driving the seedling tray 5 to rotate slowly. The rotational speed of the seedling tray 5 is determined by the transmission ratio of the reduction gear mechanism to ensure that the seedling holes on the seedling tray 5 can sequentially pass through different areas of the seedling storage chamber to complete the seedling separation operation.

[0023] An auxiliary box 14 is fixedly connected to one side of the seedling box 2. Auxiliary rollers are rotatably mounted on both sides of the auxiliary box 14, and these rollers engage with the guide rail grooves of the slide rail frame 4. The auxiliary rollers and the main rollers are on the same plane to enhance the stability of the seedling box 2. A rectangular opening is provided at the junction of the auxiliary box 14 and the seedling box 2. A vertically mounted guide post is fixedly connected inside the auxiliary box 14, and a horizontally mounted slide rod 16 is slidably connected to the guide post. A strip scraper 15 is fixedly connected to one end of the slide rod 16, and a cleaning brush 8 is mounted on the strip scraper 15, which contacts the surface of the seedling tray 5. A double-ended bracket is connected to the other end of the slide rod 16, and pins are fixedly connected to both ends of the double-ended bracket. Two turntables are provided inside the auxiliary box 14, and the turntables are connected to the auxiliary rollers via a transmission belt. Elliptical grooves are provided on the surface of the turntables, and these grooves engage with the pins. When the seedling box 2 moves back and forth on the slide rail frame 4, the auxiliary rollers rotate accordingly, which drives the turntable to rotate through the transmission belt. The elliptical groove of the turntable pushes the pin to move back and forth, thereby driving the slide rod 16 and the strip scraper 15 to move back and forth along the guide column, so that the cleaning brush 8 cleans the surface of the seedling tray 5.

[0024] An elastic sealing layer 17 is fixedly connected to the slide bar 16, and the elastic sealing layer 17 is sealed to the inner wall of the auxiliary box 14. The elastic sealing layer 17 is located between the guide post and the strip scraper 15, isolating the internal space of the auxiliary box 14 into a closed chamber. The double-end bracket and the turntable are both located in the closed chamber. Airflow channels are opened inside the strip scraper 15 and the slide bar 16. Multiple airflow outlets are provided on one side of the cleaning brush 8 of the strip scraper 15. An exhaust pipe 13 connected to the airflow channel is fixedly connected to the double-end bracket. An air inlet pipe 12 is fixedly installed on the top of the auxiliary box 14. One-way valves are provided on both the air inlet pipe 12 and the exhaust pipe 13. A dust cover is fixedly connected to the top of the air inlet pipe 12. When the strip scraper 15 moves back and forth, the air in the airflow channel forms a circulating airflow through the air inlet pipe 12 and the exhaust pipe 13, further enhancing the cleaning effect.

[0025] A detection box 9 is fixedly connected to the side of the seedling box 2 opposite to the rectangular opening. An image acquisition module is installed inside the detection box 9. A transparent observation window 10 is fixedly installed at the junction of the detection box 9 and the seedling box 2. The image acquisition module monitors the working status of the seedling tray 5 in real time through the transparent observation window 10. Electromagnetic clutches 11 are fixedly connected to both sides of the auxiliary box 14. The electromagnetic clutches 11 are used to drive the auxiliary rollers and the turntable. When the image acquisition module detects an abnormal working status of the seedling tray 5, the electromagnetic clutches 11 disconnect the drive connection, stopping the reciprocating movement of the cleaning brush 8, so as to facilitate troubleshooting or maintenance.

[0026] The working process of this utility model is as follows: After the drive box 3 is started, its output shaft drives the seedling box 2 to reciprocate on the slide rail frame 4 through the crank-connecting rod mechanism. At the same time, the pawl structure on the main roller cooperates with the reduction mechanism to convert the rotational motion of the main roller into the slow rotation of the seedling tray 5. During the rotation, the seedling holes on the seedling tray 5 pass through different areas of the seedling storage chamber in sequence. The Chinese medicinal herb seedlings in the seedling storage chamber are guided into the seedling holes by the arc-shaped baffle 6 and the inclined baffle 7 to complete the seedling separation operation. The rotation speed of the seedling tray 5 is controlled by the transmission ratio of the reduction mechanism to ensure that the seedling holes can be evenly distributed with seedlings. When the seedling box 2 reciprocates, the auxiliary roller rotates accordingly, driving the turntable to rotate through the transmission belt. The elliptical groove of the turntable pushes the pin to reciprocate, thereby driving the slide rod 16 and the strip scraper 15 to reciprocate along the guide column, so that the cleaning brush 8 cleans the surface of the seedling tray 5. The elastic sealing layer 17 isolates the internal space of the auxiliary box 14 into a closed chamber to prevent dust from entering and affecting the cleaning effect. The airflow channels within the strip scraper 15 and slide bar 16 form a circulating airflow through the air inlet pipe 12 and exhaust pipe 13, further enhancing the cleaning effect. The image acquisition module within the detection box 9 monitors the working status of the seedling tray 5 in real time through the transparent observation window 10. When an abnormality is detected, the electromagnetic clutch 11 disconnects the transmission connection, stopping the reciprocating movement of the cleaning brush 8 for troubleshooting or maintenance. To better enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0027] In the cultivation of Chinese medicinal herbs, the seedlings to be planted are first placed in the seedling storage chamber. The storage chamber consists of a seedling tray 5, an arc-shaped baffle 6, a sloping baffle 7, and the inner wall of the planting box 2. Its design ensures that the seedlings are evenly distributed and that the seedling separation is not affected by clumping. When the drive unit 3 is started, the output shaft drives the planting box 2 to reciprocate along the slide rail frame 4 via a crank-connecting rod mechanism. During this process, the pawl structure on the main roller cooperates with the reduction mechanism to convert the rotational motion into the slow rotation of the seedling tray 5. Since the surface of the seedling tray 5 has multiple seedling holes, these holes sequentially pass through different areas of the storage chamber. The arc-shaped baffle 6 and the sloping baffle 7 guide the seedlings into the seedling holes, completing the seedling separation operation. The rotational speed of the seedling tray 5 is determined by the gear ratio in the reduction mechanism, thus ensuring that each seedling hole can evenly receive one seedling.

[0028] As the seedling box 2 reciprocates, the auxiliary rollers rotate accordingly, driving the turntable to rotate via a transmission belt. The elliptical grooves on the turntable surface push the pins back and forth, which in turn drives the slide bar 16 and the strip scraper 15 to reciprocate along the guide post. The cleaning brush 8 on the strip scraper 15 contacts the surface of the seedling tray 5, cleaning it and preventing residue from clogging the seedling holes. The elastic sealing layer 17 isolates the internal space of the auxiliary box 14 into a closed chamber, preventing dust from entering and affecting the cleaning effect. Furthermore, the airflow channels within the strip scraper 15 and slide bar 16 form a circulating airflow through the air inlet pipe 12 and the exhaust pipe 13, further enhancing the cleaning effect. This design, combining mechanical cleaning with airflow assistance, effectively solves the problem of seedling hole clogging and improves the continuous operation capability of the device.

[0029] The image acquisition module inside the detection box 9 monitors the working status of the seedling tray 5 in real time through the transparent observation window 10. When the image acquisition module detects an abnormality on the seedling tray 5, the electromagnetic clutch 11 disconnects the transmission connection between the auxiliary roller and the turntable, stopping the reciprocating movement of the cleaning brush 8, so as to facilitate troubleshooting or maintenance. This design not only improves the intelligence level of the device, but also enhances its reliability in practical applications.

[0030] During the planting process, the guide trough guides the seedlings on the seedling tray 5 to the designated position for planting. Since the reciprocating distance of the planting box 2 is determined by the crank length in the crank-connecting rod mechanism, the accuracy of the planting position is ensured. Simultaneously, the seedling holes on the seedling tray 5, combined with the guiding effect of the arc-shaped baffle 6 and the inclined baffle 7, ensure even distribution and precise placement of the seedlings, solving the problem of insufficient quantitative control in existing devices.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
