Problems solved by technology
[0004] However, the seedling delivery device on the existing rice transplanter does not meet the precise conveying requirements of the blanket-shaped seedlings: because after detaching from the seedling tray, the strength of each independent bowl body at the bottom of the blanket-shaped seedlings is not strong enough to support the whole blanket seedlings, and they are easily deformed by extrusion. There is no positioning device on the existing seedling platform and the seedling delivery belt, so that the pot seedlings are displaced laterally with the seedling platform and the cumulative error is generated when the seedling delivery belt is longitudinally fed, so that the seedlings cannot be accurately delivered to the seedling door, and the seedling claws cannot The phenomenon of precise seedling picking

Embodiment Construction
[0018] The present invention will be further described below in conjunction with drawings and embodiments.
[0019] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, it includes a seedling delivery platform 1, a seedling delivery belt 9, a driving pulley 7, a driven pulley 11 and a ratchet mechanism; The platform 1 is provided with a fence-like seedling guardrail 3 near the upper part of the slideway 4, and the seedling picking door 5 is set on the slideway 4, and the driving pulley 7 and the driven pulley 11 are installed in the square vacancy at the bottom of the seedling delivery platform 1. Seedling delivery belt 9 on the top, the inner hole wall of driving pulley 7 is provided with ratchet tooth 8, and driving pulley shaft 10, the ratchet 12 that is fixed on it, spring 13 constitute internal ratchet gear mechanism, send seedling platform 1 seedling-putting surface A trapezoidal longitudinal positioning bar 2 is set, and a trapezoidal horizontal positioning...

The invention discloses a seedling planting machine which is used for a sprouts transmission device of bowl-blanket sprouts. A machine body supports an oblique board-shaped sprouts transmission platform through a slide way and a pulley, a sprouts transmission belt that is arranged on a driving belt wheel and a driven belt wheel is arranged in a square nick of the lower part of the sprouts transmission platform, ratchet teeth are arranged in the inner pore walls of the driving belt wheel and the driven belt wheel, and the ratchet teeth, shafts of the driving belt wheel and the driven belt wheel and pawls on the shafts form an inscribed ratchet mechanism. Trapezoidal positioning bars are arranged along the lengthwise direction of a sprouts placing surface of the sprouts transmission platform, as well as in the transverse direction of the sprouts transmission belt. The sprouts transmission device is applicable for the precise sprouts transmission of the bowl-blanket sprouts along the lengthwise and the transverse directions.
Description
technical field [0001] The invention relates to a seedling delivery device of a rice transplanter, in particular to a seedling delivery device of a rice transplanter used for blanket-shaped seedlings. Background technique [0002] Rice seedlings used for mechanized transplanting of rice have two forms of blanket seedlings and bowl-shaped seedlings at present. Blanket seedlings are mainly used for rice transplanters. Usually, the blanket-shaped seedlings are sent to the seedling door by the seedling delivery device of the transplanter, and the seedling claws pass through the seedling door to grab a rectangular-shaped seedling blanket from the whole seedling and insert it into the field. The number determines the number of plants per hole for transplanting. Generally, the seedlings grabbed are 3-5 plants, sometimes more than 6 plants. The pot-shaped seedlings are used in throwing and planting machines, and the pot seedlings are taken out of the pot bowl by means of pulling o...
