Description

Technical Field

[0001] This application relates to the field of agricultural machinery, and more particularly to a chili pepper planting machine. Background Technology

[0002] Chili peppers are one of my country's important economic crops, with a wide planting area and high demand. Traditional chili pepper cultivation mainly relies on manual labor, including ditching, seedling placement, and soil covering. This process is not only labor-intensive and inefficient, but also susceptible to human error, making it difficult to standardize plant spacing and planting depth, directly affecting germination rate and later yield. With the improvement of agricultural mechanization, transplanters are gradually being applied to the cultivation of crops such as vegetables, tobacco, and cotton, but many technical bottlenecks still exist in chili pepper cultivation.

[0003] Existing chili transplanters mostly employ chain clamp, flexible disc, or hanging cup structures, which generally suffer from poor seedling adaptability, easy seedling damage, high missed planting rate, and inconsistent planting depth. Especially during the connection between seedling feeding and planting, there is a lack of effective means to detect whether the seedlings are accurately positioned, often resulting in missed planting or seedling jamming due to seedlings not fully entering the planting mechanism, severely affecting the continuity and reliability of operations. Summary of the Invention

[0004] In view of this, this application provides a chili pepper planting machine that significantly increases the effective planting quantity per unit time through an intelligent seedling loss detection and control strategy, while eliminating seedling loss and improving planting efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: A chili pepper planting machine, comprising: Walking frame; The seedling delivery mechanism is mounted on the traveling frame and moves the chili seedlings by rotating. A seedling feeding mechanism is mounted on the traveling frame and includes a gripping component for gripping chili seedlings; The seedling planting mechanism is mounted on the traveling frame and includes a seedling spout for receiving chili seedlings transported by the seedling feeding mechanism. The control system is electrically connected to the traveling frame, the seedling delivery mechanism, the seedling feeding mechanism, and the seedling planting mechanism, and is used to control the actions of the traveling frame, the seedling delivery mechanism, the seedling feeding mechanism, and the seedling planting mechanism; Each of the seedling planting nozzles is equipped with a pressure sensor to detect whether a chili seedling has fallen in. The pressure sensor sends a detection signal to the control system. When the detected pressure value is greater than a preset pressure threshold, the control system controls the corresponding seedling planting nozzle to open. When the pressure value is less than or equal to the preset threshold, it is determined that a seedling is missing. The control system prevents the corresponding seedling planting nozzle from opening and issues an alarm signal to prompt manual replanting. And / or, each of the seedling spouts is equipped with a through-beam infrared laser sensor. The beam of the through-beam infrared laser sensor spans the falling path of the chili seedling. As the chili seedling is released from the seedling spout and falls into the chili pit, if the through-beam infrared laser sensor detects that the beam is blocked, it is determined that the chili seedling has passed normally. If any of the through-beam infrared laser sensors fails to detect a valid blocking signal, the control system issues an alarm signal, prompting manual replanting. Optionally, in the above-mentioned chili planting machine, the seedling feeding mechanism further includes: A seedling conveying assembly, which drives the gripping assembly to move in the vertical and horizontal directions; A guide fitting component is slidably fitted with the seedling delivery component and is used to guide and support the movement of the seedling delivery component.

[0006] Optionally, in the above-mentioned chili pepper planter, the seedling delivery mechanism includes: A rotating assembly includes a chain drive structure and a small drive sprocket, wherein the small drive sprocket is used to drive the chain drive structure to rotate. The first driving component is used to drive the rotation of the transmission sprocket; The seedling feeding rods are spaced apart on the chain drive structure, and the spacing between adjacent seedling feeding rods is adapted to the width of the seedling tray on which the pepper seedlings are placed, so as to be able to clamp the seedling tray. Driven by the first driving component, the transmission sprocket drives the seedling tray to rotate.

[0007] Optionally, in the above-mentioned chili pepper planter, the seedling conveying component includes: Second drive unit; A fixing block is fixedly mounted on the traveling frame; The first cam rotates under the drive of the second driving member; The moving component includes a first connecting component connected to the first cam, a conversion connector and a slider connected to the first connecting component, a portion of the first connecting component being rotatably connected to the first cam, the conversion connector including a bent portion being rotatably connected to the fixed block and forming a bending portion rotation point, and the slider being connected to the gripping component. Driven by the second driving member, the first cam rotates to move the gripping component vertically via the first connecting component, and rotates around the bending point via the conversion connector to move the gripping component horizontally.

[0008] Optionally, in the above-mentioned chili pepper planting machine, the guiding and mating component includes: The second cam rotates under the drive of the second driving member; A vertical structure, connected to the second cam, and including a slide rail; Driven by the second driving member, the sliding member slides in conjunction with the slide rail as the first cam and the second cam rotate.

[0009] Optionally, in the above-mentioned chili planting machine, the seedling beak includes a first part and a second part, the first part and the second part being able to open and close; The seedling planting facility also includes: Third driving component; A pull rope, connected to the seedling beak, is used to separate the first and second parts to allow the chili seedling to pass through; An elastic element is provided on the seedling beak and is used to close the first part and the second part; The pull rope is connected to the third driving member. The third driving member pulls the pull rope by rotating, thereby moving the seedling beak and separating the first part and the second part so that the chili seedling falls into the chili pit. The third driving member releases the pulling force of the pull rope on the seedling beak by reversing, and the first part and the second part of the seedling beak close under the action of the elastic member.

[0010] Optionally, in the above-mentioned chili pepper planter, the seedling planting mechanism further includes a fixed plate fixedly mounted on the walking frame and a connecting plate connected to the seedling planting nozzle. The connecting plate is arranged in a one-to-one correspondence with the seedling planting nozzle, and the connecting plate can slide relative to the fixed plate to adjust the spacing between adjacent seedling planting nozzles.

[0011] Optionally, in the above-mentioned chili pepper planting machine, the vertical structure includes: A support frame is fixedly mounted on the traveling frame; The second cam link is rotatably connected to the second cam, and the end of the second cam link is connected to the support frame and rotates about the crossbar of the support frame; An optical axis passes through the fixed block, the optical axis is connected to the slide rail, and the optical axis slides vertically relative to the fixed block.

[0012] Optionally, the above-mentioned chili planting machine also includes a soil-covering wheel located at the bottom of the walking frame, the soil-covering wheel being used to cover the chili planting pits with soil.

[0013] Optionally, in the above-mentioned chili planter, the walking frame includes triangular track wheels disposed at the bottom of the walking frame to enable the chili planter to move.

[0014] This application provides a chili pepper planting machine, which controls the movement of the walking frame through the activation of the control system, thereby driving the seedling delivery mechanism, seedling feeding mechanism, and seedling planting mechanism to move synchronously. While the planting machine moves, the control system can separately control the seedling delivery mechanism to transport chili pepper seedlings to the seedling feeding mechanism via rotation. The seedling feeding mechanism transports the chili pepper seedlings from the seedling feeding mechanism to the seedling planting mechanism. Each seedling planting nozzle is equipped with a pressure sensor to detect whether a chili pepper seedling has fallen in. The pressure sensor sends a detection signal to the control system. When the detected pressure value exceeds a preset pressure threshold, the control system controls the corresponding seedling planting nozzle to open. When the pressure value is less than or equal to a preset threshold, it is determined that there is a lack of seedlings. The control system prohibits the corresponding seedling spout from opening and issues an alarm signal to prompt manual replanting. And / or, each seedling spout is equipped with a through-beam infrared laser sensor. The beam of the through-beam infrared laser sensor spans the falling path of the chili seedling. When the chili seedling is released from the seedling spout and falls into the chili pit, if the through-beam infrared laser sensor detects that the beam is blocked, it is determined that the chili seedling has passed normally. If any through-beam infrared laser sensor does not detect a valid blocking signal, the control system issues an alarm signal to prompt manual replanting.

[0015] This avoids situations where the machine is idle or jammed, improving the reliability of the planter and the continuity of operations. Attached Figure Description

[0019] This application provides a chili pepper planting machine that significantly increases the effective planting quantity per unit time through an intelligent seedling loss detection and control strategy, while eliminating seedling loss and improving planting efficiency.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Figures 1-5As shown, this application provides a chili pepper planting machine, including a walking frame 1; a seedling feeding mechanism 2, mounted on the walking frame 1, which moves the chili pepper seedlings by rotation; a seedling feeding mechanism 3, mounted on the walking frame 1, including a gripping component for gripping chili pepper seedlings; a seedling planting mechanism 4, mounted on the walking frame 1, including a seedling planting spout 401 for receiving the chili pepper seedlings conveyed by the seedling feeding mechanism 3; and a control system, electrically connected to the walking frame 1, seedling feeding mechanism 2, seedling feeding mechanism 3, and seedling planting mechanism 4, for controlling the actions of the walking frame 1, seedling feeding mechanism 2, seedling feeding mechanism 3, and seedling planting mechanism 4; wherein, each seedling planting spout 401 is provided with a pressure sensor for detecting whether a chili pepper seedling has fallen into it, and the pressure sensor sends the detection signal to the control system. When the detected pressure value is greater than a preset pressure threshold, the control system controls the corresponding seedling spout 401 to open; when the pressure value is less than or equal to the preset threshold, it is determined that there is a lack of seedlings, the control system prohibits the opening of the corresponding seedling spout 401 and issues an alarm signal to prompt manual replanting; and / or, each seedling spout 401 is equipped with a through-beam infrared laser sensor at its outlet. The beam of the through-beam infrared laser sensor spans the falling path of the chili seedling. When the chili seedling is released from the seedling spout 401 and falls into the chili pit, if the through-beam infrared laser sensor detects that the beam is blocked, it is determined that the chili seedling has passed normally. If any through-beam infrared laser sensor does not detect a valid blocking signal, the control system issues an alarm signal to prompt manual replanting.

[0022] It should be noted that the gripping component includes an envelope gripper and a gripper fixing plate 404 for placing the gripper. Multiple grippers are provided to grip multiple chili seedlings. A seedling delivery tube 6 is provided between the gripper and the seedling spout 401, so that the chili seedlings fall into the seedling spout 401 through the seedling delivery tube 6 under their own weight. The seedling delivery tube 6 is provided one-to-one with the gripper. The grippers are electric grippers, and the number of grippers is set according to actual needs.

[0023] Specifically, this application controls the movement of the walking frame 1 by activating the control system, which in turn drives the seedling delivery mechanism 2, the seedling feeding mechanism 3, and the seedling planting mechanism 4 to move synchronously. While the planter is moving, the control system can control the seedling delivery mechanism 2 to transport chili seedlings to the seedling feeding mechanism 3 by rotation. The seedling feeding mechanism 3 is used to transport the chili seedlings from the seedling feeding mechanism 3 to the seedling planting mechanism 4. A pressure sensor is installed in the beak of the seedling planting mechanism 4. When the chili seedling enters the seedling planting beak 401, the pressure sensor detects the pressure on the seedling planting beak 401 and sends the pressure signal to the control system. The control system determines whether the chili seedling has entered the seedling planting beak 401 correctly based on the pressure signal. After confirming that the chili seedling is in place, the control system controls the seedling planting beak 401 to open so that the chili seedling is planted in the chili pit. Then the seedling planting beak 401 closes to complete the transplanting. The control system then controls the walking frame 1 to continue moving forward, while the chili seedlings on the seedling delivery mechanism 2 move forward at the same time.

[0024] This not only enables the semi-automatic setting of the chili pepper planter, improving planting efficiency and practicality.

[0025] It should be noted that, in one example, the control system independently controls each seedling duckbill 401. The pressure sensor sends a detection signal to the control system. When the detected pressure value is greater than a preset threshold, the control system activates the corresponding planting nozzle 401. When the pressure value is less than or equal to the preset threshold, it is determined that there is a shortage of seedlings. The control system then prevents the corresponding planting nozzle 401 from activating and issues an alarm signal, prompting manual replanting. In this way, a pre-planting detection mode is achieved, avoiding the ineffective activation of the planting nozzle 401 and reducing mechanical wear.

[0026] In another example, the control system performs coordinated control of all the seedling beaks 401. That is, the control system controls all the seedling beaks 401. The opening and closing of all the seedling beaks 401 (each seedling beak 401 is equipped with a pull rope 402) is achieved by tying all the pull ropes 402 of the seedling beaks together with a single pull rope 402 (described later), and then connecting it to a third drive unit (described later). The control system controls the third drive unit to start. At this time, driven by the third drive unit, all the seedling beaks 401 open and close simultaneously. Therefore, the seedling beaks 401... A through-beam infrared laser sensor is installed at the seedling outlet of 1. When the seedling falls from the seedling beak 401, the through-beam infrared laser sensor can detect whether the chili seedling has passed by to determine whether there is a missed planting. If the through-beam infrared laser sensor does not detect the falling chili seedling, it will send a missing seedling signal to the control system. The control system will determine the missing seedling and issue an alarm signal, and the seedling will be manually replanted. In this mode, it is not possible to prevent the chili seedling from being unloaded before planting, so it is verified after planting. In this way, the missed planting caused by the chili seedling getting stuck or slipping can be avoided, and the detection coverage rate can be improved.

[0027] It is also acceptable. The control system independently controls each seedling beak 401 and sets up a pressure sensor inside the seedling beak 401. A through-beam infrared laser sensor is set at the seedling outlet of the seedling beak 401. In this way, the pressure sensor and the through-beam infrared laser sensor can also be used together. One is for pre-planting detection and the other is for post-planting verification, forming a dual detection mechanism for missing seedlings, which effectively reduces the risk of misplanting and missing planting.

[0028] The seedling feeding mechanism 3 further includes: a seedling conveying component, which drives the gripping component to move vertically and horizontally; and a guiding and cooperating component, which slides with the seedling conveying component and is used to guide and support the movement of the seedling conveying component. This can be understood as follows: when the seedling conveying component drives the gripper to grasp the chili seedling, the gripper descends and grasps the seedling. After grasping the seedling, the gripper rises under the drive of the seedling conveying component and begins to move horizontally. When it reaches the position of the seedling conveying tube 6, the gripper descends and releases the seedling, and then rises again under the drive of the seedling conveying component and begins to move horizontally back to the position of grasping the seedling, thus repeating the cycle.

[0029] During this process, the guiding and cooperating components guide the horizontal movement of the seedling delivery components and cooperate with the vertical movement of the seedling delivery components to achieve the clamping, transportation and release of chili seedlings. The cooperation between the two realizes the complete process of automatic clamping-lifting-horizontal transportation-positioning release-resetting of chili seedlings, improving transplanting efficiency and operation accuracy.

[0030] In an optional embodiment, the seedling delivery mechanism 2 includes: a rotating assembly, comprising a chain drive structure 203 and a small transmission sprocket 201, the small transmission sprocket 201 driving the chain drive structure 203 to rotate; a first driving member, for driving the rotation of the small transmission sprocket 201; and seedling delivery rods 202, spaced apart on the chain drive structure 203, the spacing between adjacent seedling delivery rods 202 being adapted to the width of the seedling tray for holding the seedlings; wherein, driven by the first driving member, the small transmission sprocket 201 drives the seedling tray to rotate. A support plate is provided on the outer side of the rotating assembly, and the support plate is fixedly mounted on the traveling frame 1, for example, by bolts. The traveling frame 1 includes multiple layers, with the rotating assembly located on the top layer, and the other layers forming placement areas for placing the seedlings or seedling trays. This allows for the placement of a large number of seedlings at once, enabling the seedlings to move synchronously with the traveling frame 1, avoiding manual handling, saving manpower, and improving the practicality of the planting machine.

[0031] In addition, four bearing bushes are bolted to the outer side of the support plate. The chain drive structure 203 includes two sprocket shafts, four sprockets, and two chains. The two sprockets are mounted on one sprocket shaft, and keyways are provided on the sprocket shaft to fix the sprockets, allowing the sprocket shaft and sprockets to rotate synchronously. Bolts are used to fix the axial movement of the sprockets on the sprocket shaft. It should be noted that both ends of the sprocket shaft pass through the bearing bushes to reduce rotational friction. The keyways fix the circumferential rotation of the sprocket 4, and the bearing bushes support and fix the sprocket shaft. Two sprockets are connected to a chain at the front and rear, and a small transmission sprocket 201 is provided on the outside of the support plate. The small transmission sprocket 201 is connected to one of the sprocket shafts and is driven by a first driving component, such as a motor, to rotate the sprocket shaft connected to it. This, in turn, drives the sprocket connected to the sprocket shaft to rotate. The sprocket then transmits the rotation to other sprockets through the chain to realize the rotation of the rotating component.

[0032] Multiple holes are provided on both chains. The seedling delivery rod 202 passes through the holes on the two chains and is fixed between the two chains. The distance between adjacent seedling delivery rods 202 is adapted to the width of the seedling tray. In the width direction of the seedling tray, the seedling tray has a bending groove formed by bending downwards. The seedling delivery rod 202 extends into the bending groove and has a clamping force on the seedling tray, so that the seedling tray will not detach from the rotating component when rotating downwards, avoiding damage to the seedling tray and saving costs.

[0033] Furthermore, the seedling delivery assembly includes: a second driving member; a fixed block 301, fixedly mounted on the walking frame 1; a first cam 302, connected to the output shaft of the second driving member and rotating synchronously with the output shaft; and a moving assembly, including a first connecting assembly connected to the first cam 302, a conversion connecting member 303 connected to the first connecting assembly, and a sliding member 304. A portion of the first connecting assembly is rotatably connected to the first cam 302. The conversion connecting member 303 includes a bent portion, which is rotatably connected to the fixed block 301 and forms a turning point of the bent portion. The sliding member 304 is connected to the gripping assembly. Under the drive of the second driving member, the first cam 302 rotates to drive the gripping assembly to move vertically through the first connecting assembly, and rotates around the turning point of the bent portion through the conversion connecting member 303 to move the gripping assembly horizontally.

[0034] It should be noted that the second driving component is a motor; the first connecting assembly includes a first cam link 310 rotatably connected to the first cam 302 and a first rod end spherical bearing 311 connected to the end of the first cam link 310.

[0035] Specifically, the vehicle frame 1 is provided with two bearing seats 312, which are arranged opposite to each other and are pierced by a camshaft 313. A first cam 302 is located between the opposite bearing seats 312 and is fitted with the camshaft 313 so as to rotate synchronously with the camshaft 313. The vehicle frame 1 is also provided with a support frame 307, which is arranged opposite to the bearing seats 312. One end of the first cam connecting rod 310 is rotatably connected to the support member, and the other end is connected to a first rod end joint bearing 311. The connection point between the first cam connecting rod 310 and the first cam is located between the two ends of the first cam connecting rod 310. A chain drive assembly is provided at the end of the camshaft 313 (this end is located outside the two opposite bearing seats 312). The chain drive is driven by a second drive member to drive the rotation of the camshaft 313, thereby driving the first cam 302 to rotate.

[0036] by Figure 4 For example, in this state, the gripper is above the seedling tube 6. The second drive unit is activated, the first cam 302 starts to rotate, the end of the first cam connecting rod 310 rotates around the crossbar on the support frame 307, and the other end moves up and down with the rotation of the first cam 302. When the other end of the first cam connecting rod 310 moves upward, the first rod end joint bearing 311 moves upward, the conversion connector 303 rotates counterclockwise on the fixed block 301, and drives the gripper to slide to the left. When the gripper slides above the seedling tray, the gripper grabs the pepper seedlings downward and lifts them up. The first rod end joint bearing 311 rotates counterclockwise and moves downward under the rotation of the first cam 302. The gripping component slides to the right. When it slides above the seedling tube 6, the gripper moves downward and releases the pepper seedlings and then quickly rises back. The pepper seedlings slide along the seedling tube 6 into the pepper pit. This process is repeated to transport pepper seedlings.

[0037] Furthermore, the guiding and cooperating assembly includes: a second cam 305, which rotates under the drive of the second driving member; a vertical structure connected to the second cam 305, and including a slide rail 306; wherein, under the drive of the second driving member, as the first cam 302 and the second cam 305 rotate, the sliding member 304 slides in cooperation with the slide rail 306. The second cam 305 passes through the camshaft 313 and is located between two bearing seats 312, and rotates synchronously with the camshaft 313, thus enabling the first cam 302 and the second cam 305 to rotate synchronously, and the slide rail 306 not only guides the sliding member 304 but also provides support, thereby improving the practicality of the planting machine.

[0038] Furthermore, the seedling-planting spout 401 includes a first part and a second part, which can open and close; the seedling-planting mechanism 4 also includes: a third drive member; a pull rope 402, connected to the seedling-planting spout 401 and used to separate the first part and the second part to allow the chili seedling to pass through; an elastic member 403, disposed on the seedling-planting spout 401 and used to close the first part and the second part; wherein, the pull rope 402 is connected to the third drive member, and the third drive member pulls the pull rope 402 by rotating, thereby planting the spout 401, separating the first part and the second part so that the chili seedling falls into the chili pit; the third drive member releases the pulling force of the pull rope 402 on the seedling-planting spout 401 by reversing, and the first part and the second part of the seedling-planting spout 401 close under the action of the elastic member 403.

[0039] It should be noted that the third driving component is a motor; the seedling beak 401 and the pull rope 402 are set in a one-to-one correspondence; the elastic component 403 is a spring.

[0040] The above settings improve the intelligence of the Duckbill 401 seedling planting system.

[0041] Furthermore, the seedling planting mechanism 4 also includes a fixed plate 404 fixedly mounted on the traveling frame 1 and a connecting plate 405 connected to the seedling spouts 401. The connecting plate 405 corresponds one-to-one with the seedling spouts 401, and can slide relative to the fixed plate 404 to adjust the distance between adjacent seedling spouts 401. The connecting plate 405 and the fixed plate 404 are fixedly connected by bolts. Multiple adjustment holes are provided on the fixed plate 404, allowing the bolts to pass through different adjustment holes to adjust the distance between adjacent seedling spouts 401, thus adapting to different planting needs and improving the practicality of the planting machine.

[0042] The vertical structure includes: a support frame 307, fixedly mounted on the vehicle frame 1; a second cam link 308, rotatably connected to a second cam 305, with the end of the second cam link 308 connected to the support frame 307 and rotating around the crossbar of the support frame 307; an optical axis 309, through which a fixing block 301 passes, connected to a slide rail 306, and sliding vertically relative to the fixing block 301; a connector for connecting the opposing optical axes 309 and located at the bottom of the optical axes 309; and a vertical link, one end connected to the second cam link 308 and the other end connected to the connector.

[0043] Specifically, the second driving component drives the camshaft 313 to rotate through a chain and sprocket transmission structure. The second cam 305 passes through the camshaft 313 and rotates synchronously with the camshaft 313. As the second cam 305 rotates, the end of the second cam connecting rod 308 rotates around the crossbar of the support frame 307, and the other end connected to the second rod end joint bearing 314 moves up and down. At the same time, the optical axis 309 slides along the fixed block 301 to realize the vertical movement of the structure.

[0044] It should be noted that the optical axis 309 is connected to the second rod end joint bearing 314 through the optical axis 309 connecting plate 405 and the connecting shaft. In this way, when the second rod end joint bearing 314 moves, the optical axis 309 can drive the slide rail 306 to move up and down.

[0045] The vertical structure's motion principle is simple and reliable.

[0046] In an optional embodiment, the chili planter also includes a soil-covering wheel 5 located at the bottom of the walking frame 1, which is used to cover the chili planting holes with soil. This avoids manual soil covering, saves manpower, and improves the intelligence of the planter.

[0047] In an optional embodiment, the walking frame 1 includes triangular track wheels 101 disposed at the bottom of the walking frame 1 to enable the chili pepper planter to move. The triangular track wheels 101 are suitable not only for plains but also for hilly areas, improving the practicality of the planter.

A seedling feeding mechanism is mounted on the traveling frame and includes a gripping component for gripping chili seedlings; The seedling planting mechanism is mounted on the traveling frame and includes a seedling spout for receiving chili seedlings transported by the seedling feeding mechanism. The control system is electrically connected to the traveling frame, the seedling delivery mechanism, the seedling feeding mechanism, and the seedling planting mechanism, and is used to control the actions of the traveling frame, the seedling delivery mechanism, the seedling feeding mechanism, and the seedling planting mechanism; Each of the seedling planting nozzles is equipped with a pressure sensor to detect whether a chili seedling has fallen in. The pressure sensor sends a detection signal to the control system. When the detected pressure value is greater than a preset pressure threshold, the control system controls the corresponding seedling planting nozzle to open. When the pressure value is less than or equal to the preset threshold, it is determined that a seedling is missing. The control system prevents the corresponding seedling planting nozzle from opening and issues an alarm signal to prompt manual replanting. And / or, each of the seedling spouts is equipped with a through-beam infrared laser sensor. The beam of the through-beam infrared laser sensor spans the falling path of the chili seedling. When the chili seedling is released from the seedling spout and falls into the chili pit, if the through-beam infrared laser sensor detects that the beam is blocked, it is determined that the chili seedling has passed normally. If any of the through-beam infrared laser sensors does not detect a valid blocking signal, the control system issues an alarm signal to prompt manual replanting.
