Novel belt rice seedling conveying mechanism of rice transplanter

Abstract

The invention discloses a novel belt rice seedling conveying mechanism of a rice transplanter, relating to the agricultural machinery equipment. The rice seedling conveying mechanism comprises a rice seedling carrying platform, a rice seedling conveying belt, a rice seedling conveying wheel axel, a driving rice seedling conveying wheel axel, a driven rice seedling conveying wheel axel, a synchronous transmission connecting rod, a roller column clutch assembly and a tensioning spring, wherein an upper row and a lower row of vacancy holes are formed at the lower part of the rice seedling carrying platform; the driving rice seedling conveying wheel axel is positioned on the rice seedling carrying platform through a bracket and transversely penetrates through the rear side of the lower row of vacancy holes; the driven rice seedling conveying wheel axel is positioned on the rice seedling carrying platform through another bracket and transversely penetrates through the rear side of the upper row of vacancy holes; the rice seedling conveying wheel axel is arranged between the driving rice seedling conveying wheel axel and the driven rice seedling conveying wheel axel; the synchronous transmission connecting rod is connected between the rice seedling conveying wheel axel and the driving rice seedling conveying wheel axel; chain wheels are sleeved at the part where the driving rice seedling conveying wheel axel and the driven rice seedling conveying wheel axel correspond to the vacancy holes; the rice seedling conveying belt is installed out of the chain wheels of the upper and lower vacancy holes at corresponding parts; the roller column clutch assembly is installed at one end of the driving rice seedling conveying wheel axle; one end of the tensioning spring is hooked on the driven rice seedling conveying wheel axel; and the other end of the tensioning spring is hooked on the bracket at the upper side of the upper vacancy holes.

Description

technical field [0001] The invention relates to an agricultural mechanical equipment, in particular to a rice seedling delivery mechanism of a rice transplanter. Background technique [0002] The existing seedling delivery mechanisms of rice transplanters include ratchet type, roller type, and single belt type. The ratchet seedling delivery mechanism and the roller seedling delivery mechanism have defects such as unstable seedling delivery, unevenness, damage to the root system of the seedlings, and missing seedlings; The mechanism is more complicated, the failure rate is high, the use and maintenance are inconvenient and the cost is high. At the same time, these seedling delivery mechanisms are mainly used for ordinary blanket-shaped seedlings. Because the bowl-shaped blanket-shaped seedlings have more advantages, the use of bowl-shaped blanket-shaped seedling raising trays for seedling cultivation is rapidly popularized and applied. The bowl-shaped blanket-shaped seedlings...

[0002] The existing seedling delivery mechanisms of rice transplanters include ratchet type, roller type, and single belt type. The ratchet seedling delivery mechanism and the roller seedling delivery mechanism have defects such as unstable seedling delivery, unevenness, damage to the root system of the seedlings, and missing seedlings; The mechanism is more complex, the failure rate is high, the use and maintenance are inconvenient and the cost is high

At the same time, these seedling delivery mechanisms are mainly used for ordinary blanket-shaped seedlings. Because the bowl-shaped blanket-shaped seedlings have more advantages, the use of bowl-shaped blanket-shaped seedling raising trays for seedling cultivation is rapidly popularized and applied. The bowl-shaped blanket-shaped seedlings require accurate and timely seedling delivery. The ratchet, roller, and single-belt seedling feeding mechanisms can no longer meet the requirements of use
