Problems solved by technology
[0005] The current common seedling delivery device, due to the unstable transmission of the mechanism, the large vibration of the whole machine, the large inertial force, etc., may easily cause the seedlings to vibrate from the pot body, and there are cumulative errors in the longitudinal delivery of the seedlings, resulting in the inability of the seedlings to be accurately delivered to the seedling picking position. affect the success rate of seedling

Embodiment Construction
[0035] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.
[0036] see Figure 1~Figure 9 , a preferred embodiment of the vertical seedling delivery mechanism of the transplanter of the present invention-frame 21, seedling box 1, top seedling mechanism, horizontal seedling delivery device, vertical seedling delivery device and transmission system are set on the frame 21, wherein:
[0037] see figure 1 - Figure 5As shown, the main frame of the seedling box 1 is welded by square steel pipes. A certain number of seedling box partitions 33 are arranged in the main frame to form a plurality of seedling-carrying areas in the seedling box 1. The seedling box partitions Plate 33 sides form a certain angle with the vertical plane of seedling case 1, and this angle is identical with seedling dish 4 pot body si...

A longitudinal seedling sending mechanism of a transplanting machine comprises a seedling box, wherein seedling trays are arranged in the seedling box; a row of feeding holes are formed in each seedling tray, and seedling ejecting rods of a seedling ejection mechanism correspond to the seedling trays. The longitudinal seedling sending device comprises an incomplete second gear mounted on an unlocking cam shaft coaxially with an unlocking cam, the incomplete second gear is connected with a braking hub shaft, a braking hub with a brake pad is mounted on the braking hub shaft, the brake pad is fixedly connected with an unlocking rod mounting sleeve, the unlocking rod mounting sleeve where a tension spring mounting rod and an unlocking rod are welded is mounted on an unlocking rod mounting shaft, a tensioned tension spring is arranged between the tension spring mounting rod and the rack, and the unlocking rod and the unlocking cam are coplanar; the braking hub shaft is connected with a hexagonal shaft through a gear, multiple longitudinal shifting rods are arranged on the hexagonal shaft in a clearance fit manner, the number of the longitudinal shafting rods is matched with the number of the seedling trays in the seedling box and the number of the seedling ejecting rods, and the longitudinal shifting rods are meshed with the feeding holes of the seedling trays, so that the longitudinal shifting rods can shift the seedling trays downwards through the longitudinal shifting rods.
Description
technical field [0001] The invention relates to a transplanter in agricultural machinery, in particular to a vertical seedling delivery mechanism of a transplanter. Background technique [0002] In our country, the planting methods of crops are generally divided into two types: direct seeding and seedling transplanting. Although the man-hours and manpower invested in seedling cultivation and transplanting are much greater than those of direct seeding, compared with the direct seeding cultivation method, seedling cultivation and transplanting is through intensive seedling cultivation of crop seeds during the sowing season. Transplanted to the field for growth, therefore, through the planting method of centralized seedling cultivation and transplanting, the planting season of the crops can be advanced, the contradiction between the stubble in the crop planting season can be alleviated, and the crop planting season can be extended, which is conducive to expanding the planting a...
