Description

Technical Field

[0001] The utility model relates to agricultural machinery, in particular to a high-speed rice seedling taking device which can take out rice seedlings six times in one rotation of rice seedling pots. Background Art

[0002] The rice seedling pulling mechanism in the rice seedling pot currently under development in China has a rice seedling pulling claw that can easily pull out adjacent seedlings when the rice seedling tray is vertical.

[0003] At present, the rice seedling tray of the rice seedling pulling mechanism under development in China adopts a chain transmission in the longitudinal direction. Because of the polygonal effect of the chain transmission and the easy elongation of the chain, it is not suitable for high-speed longitudinal delivery of the rice seedling tray.

[0004] At present, the longitudinal seedling sending transmission mechanism of the rice seedling pulling mechanism under development in China adopts a longitudinal seedling sending cam to lift the longitudinal seedling sending passive cam shaft. At the same time, the longitudinal seedling sending passive cam shaft drives the ratchet mechanism to intermittently send the seedlings longitudinally. This mechanism has large vibrations and is unstable in manufacturing, installation and maintenance. It is not suitable for the longitudinal seedling sending transmission mechanism of the rice seedling tray with high-speed longitudinal seedling sending.

[0005] The rice seedling pulling mechanism under development in China currently uses a high-pair mechanism for clamping the seedling pulling claws, which has the disadvantages of high wear, low efficiency, and a small friction coefficient for clamping the seedlings, and is not suitable for high-speed longitudinal delivery of rice seedlings in the seedling tray. Summary of the invention

[0006] In view of this, the purpose of the utility model is to provide a high-speed rice seedling taking device which can take out rice seedlings six times in one rotation of rice seedlings in a pot.

The device comprises a high-speed longitudinal seedling sending wheel assembly, an inner guide rail of a seedling tray, an outer guide rail for gathering seedlings on the seedling tray, a longitudinal seedling sending transmission mechanism, a high-speed seedling taking mechanism for pulling out rice seedlings six times with one rotation of a rice seedling tray, a seedling pulling claw assembly, a longitudinal seedling sending transmission mechanism shield, and a box body. The rice seedlings in the rice seedling tray move along the inner guide rail of the seedling tray under the action of the outer guide rail for gathering seedlings on the seedling tray. The high-speed longitudinal seedling sending wheel intermittently pushes the rice seedlings in the rice seedling tray to a pulling position under the action of the longitudinal seedling sending transmission mechanism. The high-speed seedling taking mechanism can pull out rice seedlings six times with one rotation of a rice seedling tray, thereby realizing high-speed seedling taking.

[0009] As a preferred solution, the seedling tray outer guide rail isolates and brings each rice seedling into the seedling pulling claw assembly, and the seedling tray outer guide rail and the seedling tray inner guide rail are arranged at the upper left corner of the box body.

[0010] As a preferred solution, the high-speed longitudinal seedling delivery wheel is arranged in the middle of the guide rail inside the seedling tray.

[0011] As a preferred solution, the longitudinal seedling feeding transmission mechanism is arranged on the right side of the box body.

[0012] As a preferred solution, the high-speed seedling taking mechanism that pulls out the seedlings six times in one rotation is arranged under the box body.

The rice seedlings in the pot move along the inner guide rail of the seedling tray under the action of the seedling gathering outer guide rail of the seedling tray. The high-speed longitudinal seedling sending wheel intermittently pushes the rice seedlings in the pot to the seedling pulling position under the action of the longitudinal seedling sending transmission mechanism. The high-speed seedling taking mechanism can pull out seedlings six times in one rotation, thereby realizing high-speed seedling taking.

[0030] The specific structure of each mechanism is described in detail below with reference to the accompanying drawings.

[0031] 1. Inner guide rail of seedling tray and outer guide rail of seedling tray

[0032] Please refer to Figure 2 The inner guide rail 2 of the seedling tray and the outer guide rail 3 of the seedling tray are arranged at the upper left corner of the box body 8. The inner guide rail 2 of the seedling tray is fixedly connected to the box body 8 with two fixing rods, and the outer guide rail 3 of the seedling tray is fixedly connected to the box body 8 with four fixing rods.

[0033] The inner guide rail 2 of the seedling tray is arranged in the middle of the outer guide rail 3 of the seedling tray.

[0034] The inner guide rail 2 of the seedling tray and the outer guide rail 3 of the seedling tray form a U-shaped rice seedling channel.

[0035] The upper opening of the rice seedling pot passage is the rice seedling pot entrance.

[0036] The lower opening of the rice seedling pot channel is the rice seedling pot tray outlet.

[0037] The rice seedlings in pots and the seedling tray move in a U-shaped groove formed by the inner guide rail 2 of the seedling tray and the outer guide rail 3 of the seedling tray.

[0038] The number of the outer guide rails 3 for gathering the seedlings in the seedling tray is one more than the number of the transverse holes in the seedling tray, and the number of the inner guide rails 2 in the seedling tray is at least two.

[0039] 2. High-speed longitudinal seedling wheel assembly

[0040] Please refer to Figure 3 The high-speed longitudinal seedling sending wheel assembly 1 is composed of a driven gear 1-1, a high-speed longitudinal seedling sending wheel shaft 1-2, a high-speed longitudinal seedling sending wheel 1-3, a high-speed longitudinal seedling sending wheel right side plate 1-4, a high-speed longitudinal seedling sending wheel left side plate 1-5, and a high-speed longitudinal seedling sending pin tooth 1-6.
