Embodiment Construction
[0032] The present invention will be further described below in conjunction with accompanying drawing.
[0033] Such as figure 1 , 2 , shown in , 3a, 3b and 6, rice pot seedling transplanter seedling box includes seedling box casing 10, active seedling tray conveying mechanism, driven seedling tray conveying mechanism, seedling box base 18, seedling tray conveying gear mechanism 8, Horizontal box-moving mechanism, box-moving guide rail support frame 7, longitudinal ratchet toggle mechanism 17, pressure plate assembly, seedling box support rod 19 and seedling box support wheel 26; guide rail 15 is fixed on the top of seedling box base 18, and the box-moving guide rail supports The upper end of frame 7 is fixed on the seedling box casing 10, and the lower end and guide rail 15 of moving box guide rail bracing frame 7 constitute sliding pairs. Seedling box supporting bar 19 is fixed on the seedling box base 18; Seedling box supporting wheel 26 is fixed on the seedling box casin...

The invention discloses a rice seedling tank of a rice block seedling planting machine and a working method of the rice seedling tank. A conventional rice seedling tank is not high in precision. The rice seedling tank comprises a rice seedling tank body, a drive rice seedling tray conveying mechanism, a driven rice seedling tray conveying mechanism, a rice seedling tray conveying gear mechanism, atransverse tank moving mechanism and a longitudinal ratchet wheel shifting mechanism. The rice seedling tray conveying gear mechanism of the rice seedling tank drives feeding of rice seedling trays in a similar pinion and rack movement mode, each tooth of a gear corresponds to each row of seedling holes in a rice seedling tray, and then precise stepper rice seedling feeding is achieved; comparedwith a conventional rice seedling feeding mode of chains and iron wires, the mode is high in stability, and the rice seedling feeding precision can be improved; the driven rice seedling tray conveyingmechanism adopts a combination of gears, ratchet wheels and ratchet pawls, when a phenomenon that a rice seedling tray is neglected to be placed, the rice seedling tray is pushed manually to join ina former tray of rice seedlings, and then the problems that an interval is formed between two trays of rice seedlings since the rice seedling tray is neglected to be placed, and furthermore no seedlings are planted in a section in a field in the planting process can be avoided.
Description
technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a seedling box of a rice pot seedling transplanter and a working method thereof. Background technique [0002] Nowadays, rice pot seedling transplanting machinery continues to develop. With the rapid development of transplanting arms, the rough way of transporting pot seedlings in the past using chains and iron wire seedling boxes can no longer accurately match the movement of the picking and planting mechanism. The seedling box technology is the key technology of the pot seedling transplanter. Compared with the ordinary felt seedling transplanter, the key technical difficulties of the pot seedling transplanter include the precise stepping seedling feeding technology of the pot seedling tray, the return technology of the seedling tray, and the feeding of the seedling tray. Seedling repeat positioning accuracy technology, etc. The existing bowl seedling...
