Description

Technical Field

[0001] This utility model is a rice seedling raising machine for raising seedlings, belonging to the field of rice seedling raising. Background Technology

[0002] Seedling raising is a crucial step in the success of machine transplanting, and it has higher requirements than conventional manual transplanting. Seedling raising machines are necessary in the rice seedling raising process. Currently, while seedling raising machines can automatically collect the seedling trays, this can easily cause the stacked trays to tilt or fall over, reducing the safety of the collection process. Furthermore, it requires real-time observation and timely intervention by staff, causing inconvenience to users.

[0003] Therefore, the rice seedling raising machine with patent number CN202323010501.1 can automatically and stably collect stacked seedling trays by setting side plates, feeding ports, baffles, infrared sensor switches, electric telescopic rods and storage plates, which greatly improves the safety of collecting seedling trays. By setting support plates, distance sensor switches and alarms, it can automatically remind the staff to transfer the seedling trays when they are collected to a certain height, and place empty storage plates before continuing to collect the trays, which greatly improves its ease of use.

[0004] The aforementioned patent describes a method for stacking and storing seedling trays without requiring real-time human observation. While the patent describes using side plates to limit the stacked trays on both sides, preventing tilting, the other two sides of the trays are not fully protected by the side plates described in the patent. This makes it difficult to prevent the stacked trays from tilting, and it also presents inconvenience for personnel when moving a large number of stacked trays. Therefore, this invention proposes a rice seedling raising machine that integrates a manual trolley for effectively storing seedling trays with the main machine. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rice seedling raising machine for seedling cultivation.

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

[0007] A rice seedling raising machine includes a seedling raising main unit, which includes a transmission worktable that conveys seedling trays. The discharge end of the transmission worktable is provided with a discharge port, the size of which is larger than that of the seedling trays. A baffle is embedded in the side of the transmission worktable facing the discharge port, and an infrared sensor switch is embedded in the side of the baffle facing the discharge port. A connecting plate is fixedly provided on the transmission worktable, and a support plate is fixedly provided on one side of the connecting plate. A collecting device, which is a manual trolley, is supported on the support plate. A collecting frame is fixedly provided on the manual trolley, and corresponding double-opening doors are opened on both sides of the collecting frame. The bottom of the collecting frame is open, and a storage plate is placed inside the bottom of the collecting frame. A setting plate located below the connecting plate is also fixedly provided on the transmission worktable, and a lifting component for driving the storage plate is provided on the setting plate. A distance sensor switch and an alarm are embedded in the top surface of the connecting plate.

[0008] Furthermore, the transmission workbench is equipped with a soil covering mechanism, a seeding mechanism, and a soil spreading mechanism. The manual trolley includes a frame and a trolley handle mounted on the frame, with rollers installed at the four corners of the bottom of the frame.

[0009] Furthermore, the lifting assembly consists of multiple electric telescopic rods fixed on the mounting plate. The output ends of the electric telescopic rods slide through the support plate and are all fixedly mounted on a lifting plate. The lifting plate extends into the collecting frame and contacts the storage plate.

[0010] Furthermore, the center height of the infrared sensor switch, the lower opening surface of the feed port, and the top surface of the collecting frame are all on the same plane, and the infrared sensor switch is electrically connected to the electric telescopic rod through a wire.

[0011] Furthermore, the alarm is an audible and visual alarm, which is electrically connected to a distance sensing switch via a wire. The distance sensing switch is electrically connected to a conveyor roller switch on the transmission workbench.

[0012] Furthermore, the manual trolley and the support plate are provided with positioning components, the positioning components including a positioning plate fixed on the manual trolley.

[0013] Furthermore, both the positioning plate and the support plate are provided with matching threaded holes, and a threaded rotating rod with a manual turntable is inserted into the threaded holes. The top of the support plate is provided with a pulley groove that matches the roller.

[0014] Furthermore, a conical platform is fixedly provided on the other side of the connecting plate, and a positioning hole is provided at the end of the shelf facing the lifting plate. A positioning rod is fixedly provided on the side of the lifting plate facing the shelf.

[0015] The beneficial effects of this utility model are:

[0016] By extending the lifting assembly, the storage plate inside the collecting frame is raised or lowered, positioning it below the feeding port with its top surface higher than the top surface of the collecting frame. When the conveying rollers on the seedling raising machine transport the seedling tray to the feeding port, one end of the tray contacts the surface of the storage plate. As the conveying rollers continue to transport the tray, the contact area between the tray and the storage plate slides, causing the entire tray to fall onto the surface of the storage plate. At this point, the infrared sensor detects that the upper end of the tray on the storage plate is higher than the bottom of the feeding port. The lifting assembly is then controlled to retract downwards until the upper surface of the tray is lower than the bottom surface of the feeding port. The tray then stops, and the height of the upper surface of the tray is now the same as the initial height of the storage plate. The tray continues to retract, causing the storage plate to move downwards and approach the distance sensor, triggering a sensor. The conveying rollers then stop transporting the tray and alert the operator to move the manual trolley away and replace it with a new one.

[0017] This utility model features a simple design, specifically a manual trolley adapted to an automated tray collection system. It enables orderly stacking of seedling trays, with the trays positioned within the collection frame during stacking, providing a neat and organized storage space. The double-opening doors on both sides allow for flexible opening and closing, facilitating easy loading and unloading of trays. The bottom opening design, in conjunction with the built-in shelf, ensures precise linkage. When a tray slides from the feed inlet onto the shelf, an infrared sensor triggers the retraction of an electric telescopic rod, lowering the shelf and ensuring new trays always land on a flat, height-appropriate surface, preventing stacking chaos and significantly improving collection efficiency. The design ensures precise and stable positioning, guaranteeing reliable equipment operation. The manual trolley's overall structure is primarily mechanically connected, without complex circuitry, resulting in low manufacturing costs and a low failure rate. Furthermore, the detachable connection between the positioning components and the support plate allows for flexible adaptation to different seedling raising machine models without requiring major modifications to the machine itself, demonstrating strong practicality and compatibility.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figure 1-3 This utility model provides a rice seedling raising machine for seedling cultivation, including a seedling raising main unit 1. The seedling raising main unit 1 includes a transmission worktable 2, on which seedling trays are conveyed. The discharge end of the transmission worktable 2 is provided with a discharge port 3, the size of which is larger than the seedling trays. A baffle 4 is embedded in the side of the transmission worktable 2 facing the discharge port 3. An infrared sensor switch 5 is embedded in the side of the baffle 4 facing the discharge port 3. A connecting plate 6 is fixedly provided on the transmission worktable 2, and a support plate 7 is fixedly provided on one side of the connecting plate 6. A collection device is supported on the plate 7. The collection device is a manual trolley 8. A collection frame 9 is fixedly installed on the manual trolley 8. A corresponding double-opening box door 10 is opened on both sides of the collection frame 9. The bottom of the collection frame 9 is open, and a storage plate 11 is placed inside the bottom of the collection frame 9. A setting plate 12 located below the connecting plate 6 is also fixedly installed on the transmission worktable 2. A lifting component for driving the storage plate 11 is installed on the setting plate 12. A distance sensing switch 13 and an alarm 14 are embedded on the top surface of the connecting plate 6.

[0027] See Figure 2-3 The transmission workbench 2 is equipped with a soil covering mechanism, a sowing mechanism and a soil spreading mechanism. The manual trolley 8 includes a frame and a trolley handle set on the frame. Rollers are installed at the four corners of the bottom of the frame. The manual trolley 8 ensures the subsequent transportation of seedlings.

[0028] See Figure 2-3 The lifting assembly consists of multiple electric telescopic rods 15 fixed on the setting plate 12. The output ends of the electric telescopic rods 15 slide through the support plate 7 and are all fixedly mounted on a lifting plate 16. The lifting plate 16 extends into the collecting frame 9 and contacts the placement plate 11. There are at least two electric telescopic rods 15 to ensure smooth lifting and lowering, directly driving the lifting plate 16 into the collecting frame 9 and contacting the placement plate 11, thus completing the subsequent continuous collection of seedling trays.

[0029] See Figure 2-3 The center height of the infrared sensor switch 5, the lower opening surface of the feed inlet 3, and the top surface of the collection frame 9 are all on the same plane. The infrared sensor switch 5 is electrically connected to the electric telescopic rod 15 via a wire. The alarm is an audible and visual alarm, which is electrically connected to the distance sensor switch via a wire. The distance sensor switch is electrically connected to the conveyor roller switch on the transmission workbench 2. The top surface of the collection frame of the manual trolley is on the same plane as the infrared sensor switch 5 and the lower opening of the feed inlet, ensuring that the initial sliding position of the seedling tray is accurate. At the same time, the distance sensor switch 13 on the connecting plate 6 can monitor the height of the placement plate in real time. When the seedling trays are stacked close to the distance sensor switch, the audible and visual alarm will be triggered, and the conveyor roller of the transmission workbench will be stopped simultaneously, reminding the staff to replace the trolley in time. This not only avoids the seedling trays overflowing the collection frame, but also prevents the equipment from running idle for no reason, thus improving the safety and economy of the equipment operation.

[0030] See Figure 2-5The manual trolley 8 and the support plate 7 are equipped with positioning components. The positioning components include a positioning plate 17 fixed to the manual trolley 8. Both the positioning plate 17 and the support plate 7 have matching threaded holes 18. A threaded rotating rod 19 with a manual turntable passes through the threaded hole 18. The top of the support plate 7 has a pulley groove 20 that matches the roller. A conical platform 21 is fixed on the other side of the connecting plate 6. A positioning hole 22 is opened on the end of the shelf 11 facing the lifting plate 16. A positioning rod 23 is fixed on the side of the lifting plate 16 facing the shelf 11. The pulley groove 20 at the top of the support plate can match the roller at the bottom of the trolley, guiding the trolley to return to its position quickly and avoiding docking misalignment. The positioning plate 17 on the trolley and the threaded rod 19 on the support plate are aligned. After aligning the perforations 18, insert the threaded rotating rod 19 with the manual turntable to complete the fixation, preventing the trolley from shifting due to vibration during the tray collection process. The positioning rod 23 on the lifting plate cooperates with the positioning hole 22 on the placement plate to further ensure the stability of the placement plate during lifting and lowering, preventing the seedling tray from tipping over. The positioning hole 22 and the positioning rod 23 ensure stable connection between the lifting plate 16 and the placement plate 11. The overall structure of the manual trolley is mainly mechanically connected, resulting in low manufacturing cost and low failure rate. The double-opening box door, rollers, positioning plate and other components are all conventional and easily replaceable parts, making later maintenance convenient. They are all detachable and installable with screws. Through the detachable connection design of the positioning component and the support plate, it can flexibly adapt to different models of seedling raising host without the need for large-scale modification of the seedling raising machine body.

[0031] In use, the extension of the lifting component causes the placement plate 11 inside the collecting frame 9 to rise and fall, positioning the placement plate 11 below the feeding port with its top surface higher than the top surface of the collecting frame. When the conveying rollers on the seedling raising host 1 transport the seedling tray to the feeding port 3, one end of the seedling tray contacts the surface of the placement plate 11. With continued transport by the conveying rollers, the contact area between the seedling tray and the placement plate 11 slides, causing the entire seedling tray to fall onto the surface of the placement plate 11. At this point, the infrared sensor activates. When Guan 5 detects that the upper end of the seedling tray placed on the shelf 11 is higher than the bottom of the feed inlet, it controls the lifting component to retract downwards until the upper surface of the seedling tray is lower than the bottom surface of the feed inlet and then stops. At this time, the height of the upper surface of the seedling tray is consistent with the initial surface height of the shelf 11. The seedling tray continues to retract, causing the shelf to move downwards and approach the distance sensor switch 13, and a sensor is generated. At this time, the conveyor roller stops conveying and reminds the staff to push the manual trolley 8 away and replace it with a new manual trolley 8.

[0032] This utility model is simple to set up. It features a manually operated trolley 8 adapted to an automated tray collection system, enabling orderly stacking of seedling trays. During stacking, the seedling trays are located inside the collection frame 9, providing them with a defined and protective space. The double-opening doors 10 on both sides allow for flexible opening and closing, facilitating the subsequent loading and unloading of seedling trays. The bottom opening design, in conjunction with the built-in shelf 11, ensures precise linkage. When a seedling tray slides from the discharge port 3 onto the shelf, an infrared sensor switch 5 triggers the retraction of the electric telescopic rod, lowering the shelf and ensuring that new seedling trays always land on a flat, height-appropriate surface, preventing stacking chaos and significantly improving collection efficiency. Furthermore, the design ensures precise and stable positioning, guaranteeing reliable equipment linkage. The overall structure of the trolley is mainly mechanically connected, without complex circuit components, resulting in low manufacturing cost and low failure rate. In addition, through the detachable connection design of the positioning components and support plates, it can be flexibly adapted to different models of seedling raising host without the need for large-scale modification of the seedling raising machine body, thus possessing strong practicality and compatibility. The surface of the transmission workbench 2 is also equipped with components such as servo motors and seedling tray placement racks, which can automatically place trays. Its working principle and composition structure are well known to those skilled in the art and will not be described in detail here. The surface of the transmission workbench 2 is equipped with rotatable conveying rollers, which are equipped with drive mechanisms and control switches, and are existing technologies. The soil covering mechanism, sowing mechanism, and soil spreading mechanism are also existing technologies.

[0033] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
