Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a rice transplanter. Background Technology

[0002] Existing technology, patent CN119422559A, discloses a rice transplanter, which includes a seedling pulling mechanism, a belt conveyor, a seedling tray roller, and a seedling separating grid plate. The seedling tray roller is installed behind the seedling pulling mechanism, with its center plane higher than that of the pulling mechanism. The belt conveyor is installed behind the seedling tray roller, and the seedling separating grid plate is installed between the seedling pulling mechanism and the seedling tray roller, forming an arc-shaped seedling tray channel. The seedling pulling mechanism, belt conveyor, and seedling tray roller rotate in the same direction, with the belt conveyor's conveying speed being lower than that of the seedling tray roller. The belt conveyor transports the seedling tray to the seedling tray roller, which drives the seedling tray along the arc-shaped seedling tray channel and discharges it from below. The seedling pulling mechanism pulls the seedlings from the tray upwards and throws them out from the front of the pulling mechanism to achieve planting. After the seedlings are pulled out, the seedling tray may be rolled upwards due to inertia or the continuous movement of the seedling tray roller, causing deformation and damage to the seedling tray, affecting subsequent use or equipment operation. Utility Model Content

[0003] In view of this, the present invention proposes a rice seedling thrower, which, through the guiding action of the seedling tray guide plate, enables the seedling tray to be discharged horizontally, avoiding the situation of rolling up, protecting the integrity of the seedling tray, and at the same time ensuring the stability and continuity of equipment operation.

[0004] On the one hand, this utility model provides a rice transplanter, including a seedling pulling mechanism, a belt conveyor, a seedling tray roller, and a seedling separating grid plate; the seedling tray roller is installed on the upper rear of the seedling pulling mechanism, the belt conveyor is installed behind the seedling tray roller, and the seedling separating grid plate is installed between the seedling pulling mechanism and the seedling tray roller, forming an arc-shaped seedling tray channel between the seedling tray roller and the seedling separating grid plate; a seedling tray guide plate is installed above and behind the outlet of the arc-shaped seedling tray channel, and the seedling tray guide plate to discharge the seedling tray horizontally.

[0005] To address the issue of coordinating the conveyor belt and the seedling tray, a further technical solution involves installing a connecting platform between the conveyor belt and the seedling tray, with both the conveyor belt and the connecting platform arranged horizontally.

[0006] To solve the problem of seedling tray transportation, a seedling tray input platform is installed behind the belt conveyor in a further technical solution.

[0007] To address the issue of orderly and stable feeding of seedling trays, a further technical solution includes a seedling tray roller cage comprising a transverse rod and a support plate. The support plate is evenly arranged transversely, while the transverse rod is evenly arranged circumferentially. The transverse rod drives the seedling trays to be fed in an orderly manner along the arc-shaped seedling tray channel.

[0008] In order to clean the soil in the seedling pulling trough, a further technical solution is to install a seedling cleaning roller below the seedling pulling mechanism, and install brushes on the seedling cleaning roller. The brushes are located inside the seedling pulling trough of the seedling pulling mechanism and are used to clean the soil in the seedling pulling trough.

[0009] The advantages of this rice transplanter compared to existing technologies are as follows:

[0010] This invention adds a seedling tray guide plate above the rear of the arc-shaped seedling tray channel outlet. The guide plate guides the seedling tray to be discharged horizontally from the equipment, effectively avoiding the phenomenon in traditional structures where the seedling tray rolls upward with the seedling tray cage due to inertia after the seedlings are pulled. This fundamentally reduces problems such as seedling tray breakage and tearing, ensuring the stability and continuity of equipment operation.

[0011] This utility model adopts a combined conveyor belt and seedling tray roller conveyor mode. Firstly, a connecting platform is installed between the conveyor belt and the seedling tray roller conveyor. Both the conveyor belt and the connecting platform are arranged horizontally, which solves the problem of connecting the combined conveyor belt and the seedling tray roller conveyor. Secondly, the seedling tray roller conveyor includes a horizontal rod and a support plate. The support plate is evenly arranged horizontally, and the horizontal rod is evenly arranged circumferentially. The horizontal rod drives the seedling tray to be fed in an orderly manner along the arc-shaped seedling tray channel, which solves the problem of orderly and stable feeding of the seedling tray.

[0012] This invention features a brush installed on a seedling cleaning roller. The brush is located inside the seedling pulling groove of the seedling pulling mechanism and is used to clean the soil inside the seedling pulling groove. Attached Figure Description

The seedling tray roller 4 is installed on the rear of the seedling pulling mechanism 5, the belt conveyor 1 is installed behind the seedling tray roller 4, and the seedling separating grid plate 3 is installed between the seedling pulling mechanism 5 and the seedling tray roller 4, forming an arc-shaped seedling tray channel 9 between the seedling tray roller 4 and the seedling separating grid plate 3. A seedling tray guide plate 7 is installed above and behind the outlet of the arc-shaped seedling tray channel 9, guiding the seedling tray to be discharged horizontally. Through the guiding action of the seedling tray guide plate 7, the seedling tray can be discharged horizontally, avoiding upward rolling, protecting the integrity of the seedling tray, and ensuring the stability and continuity of equipment operation.

[0020] like Figure 3 As shown, a connecting platform 2 is installed between the belt conveyor 1 and the seedling tray 4, both of which are horizontally arranged. A seedling tray input platform 8 is installed behind the belt conveyor 1. This invention employs a combined conveying mode of the belt conveyor 1 and the seedling tray 4, with the connecting platform 2 installed between them, both horizontally arranged, thus solving the problem of connecting the belt conveyor 1 and the seedling tray 4 during combined conveying.

[0021] like Figure 4 As shown, the seedling tray roller 4 includes a transverse rod 41 and a support plate 40. The support plate 40 is evenly arranged in the transverse direction, and the transverse rod 41 is evenly arranged in the circumference. The transverse rod 41 drives the seedling tray to feed in an orderly manner along the arc-shaped seedling tray channel 9, thus solving the problem of orderly and stable feeding of the seedling tray.

[0022] like Figure 1 and Figure 3 As shown, a seedling cleaning roller 6 is installed below the seedling pulling mechanism 5, and a brush 60 is installed on the seedling cleaning roller 6.
