[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 6 As shown, the present embodiment provides an adjustable seedling box for a wide and narrow row rice transplanter, comprising a frame 1 and a seedling tray adjustment mechanism and a transmission mechanism mounted on the frame 1; wherein the frame 1 is mounted on the rear side of the rice transplanter along the travel direction, the transmission mechanism comprises a conveyor belt 7 for conveying the seedling tray in the direction away from the travel of the rice transplanter, the conveying surface of the conveyor belt 7 as a whole gradually tilts downward from its input end to its output end, and a driving component for driving the conveyor belt 7 is provided on the frame 1; the seedling tray adjustment mechanism comprises at least one first slide rail 3 mounted on the frame 1, and the first slide rail 3 is located at the input end and / or output end of the conveyor belt 7, and is arranged along the conveyor belt 7. The first slide rail 3 extends horizontally perpendicular to the direction of the transplanter's movement. It is equipped with a plurality of second slide rails 4 located above the conveying surface. Each second slide rail 4 extends along the conveying direction of the conveying surface and is movably mounted on the first slide rail 3 in the direction in which the first slide rail 3 extends. The seedling tray is limited to be transmitted between the corresponding two second slide rails 4 to prevent the seedling tray from sliding in the direction perpendicular to the transmission of the conveyor belt 7 during the downward movement. Before transplanting, the corresponding number of second slide rails 4 are installed according to the number of rows to be sown, and then the spacing between the corresponding two second slide rails 4 is determined according to the size of the seedling tray, so as to realize flexible adjustment of the seedling tray slide rail spacing and the number of sowing rows. Preferably, both ends of the first slide rail 3 are connected to a slide rail support plate, and a fixed plate 2 is continuously connected between the slide rail support plate and the frame 1, preferably by bolting to mount the first slide rail 3 on the frame 1.

By energizing the first magnet assembly 13, the attraction between the first magnet assembly 13 and the second magnet assembly is achieved, and by de-energizing the second magnet assembly, the attraction between the first magnet assembly 13 and the second magnet assembly is conveniently disconnected, thereby facilitating the removal and placement of the second slide rail 4.

[0035] In a specific embodiment, a plurality of groups of transmission rollers 10 are supported at the bottom of the conveying surface, and each group of transmission rollers 10 is arranged at equal intervals along the conveying direction of the conveying surface. The transmission rollers 10 extend in a direction perpendicular to the conveying direction of the conveying surface, and both ends thereof are rotatably mounted on the frame 1, so as to support the conveying surface through the transmission rollers 10, thereby completing the supporting and conveying of the seedling tray. Preferably, both ends of the transmission rollers 10 are provided with bearing seats 9 mounted on the frame 1, and each bearing seat 9 is mounted with bearings rotatably matched with the two ends of the transmission rollers 10.

[0036] In a specific embodiment, the driving assembly includes a driving motor 14 installed on the frame 1, and the output shaft 15 of the driving motor 14 is coaxially sleeved with a driving gear 16, and the driving gear 16 is meshingly connected with a driven gear 18, and the driven gear 18 is connected to a transmission gear 17 coaxial with it and synchronously transmitted.

A rack 11 meshing with the transmission gear 17 is provided on the inner peripheral wall of the conveyor belt 7, so that the transmission gear 17 drives the rack 11 and the conveyor belt 7 to move. Specifically, the conveyor belt 7 and the rack 11 are annular structures, and the conveyor belt 7 is sleeved on the transmission gear 17 through the rack 11, so that the conveyor belt 7 can be accurately driven under the drive of the transmission gear 17.

[0037] In one embodiment, the conveyor belt 7 is equipped with two sets of drive components, and the two drive components are located at the input end or output end of the conveyor belt 7 along the conveying direction of the conveyor belt 7.

[0038] Before the rice transplanter starts working, parameters can be set through the controller. After the transplanting mechanism rotates several times, the seedling tray is placed on the conveying surface of the conveyor belt 7, and the rice transplanter starts working. After the transplanting mechanism rotates several times, the driving motor 14 drives the active gear 16 to rotate a certain angle through its output shaft 15, and the active gear 16 drives the driven gear 18 to rotate. The driven gear 18 drives the transmission gear 17 to rotate through the gear transmission rod 20, and the transmission gear 17 drives the conveyor belt 7 to transport the seedling tray, which can avoid problems such as jamming and excessive seedling delivery during the traditional structure.

[0039] In a specific embodiment, the frame 1 is provided with a mudguard located at the bottom of the conveyor belt 7, the driving motor 14 is installed at the bottom position of the mudguard, and a notch is opened on the mudguard for transmission engagement of the driving gear 16 and the driven gear 18, and a protective cover 8 is installed on the mudguard for covering the driving motor 14 and the outer peripheral side of the notch, so that the driving motor 14 and the notch can be covered inside the protective cover 8, and the driving gear 16 is located inside the protective cover 8 and is coaxially fixedly connected with the output shaft 15 of the driving click, and the driven gear 18 is located above the mudguard and is meshed with the driving gear 16 through the notch, thereby realizing protection of the driving assembly and the conveyor belt 7 through the mudguard and the protective cover 8 to prevent mud and sand from entering and affecting the conveyor belt 7 from sending rice seedlings.

[0040] In a specific embodiment, an anti-slip frame 6 is installed on the frame 1. The anti-slip frame 6 is located on the side of the second slide rail 4 away from the conveyor belt 7, and is pressed on the top position of the seedling tray, and slides with the seedling tray.

[0041] In a specific embodiment, the anti-slip frame 6 is provided with a guide frame 5 at a position corresponding to the input end of the conveyor belt 7, and the guide frame 5 gradually extends upward in a direction away from the conveyor belt 7, so that the seedling tray passes through the guide frame 5 and enters between the anti-slip frame 6 and the conveyor belt 7. And preferably, the anti-slip frame 6 includes a plurality of anti-slip bars pressed at the top position of the seedling tray, each anti-slip bar extends along the conveying direction of the conveying surface, and is evenly spaced along the direction perpendicular to the conveying surface, so that the anti-slip bars can be used to cover the seedling tray and avoid blocking the seedling tray during the conveying process.
