Problems solved by technology

Most of the existing rice transplanter feeding mechanisms are ratchet mechanisms, all of which lack a locking mechanism for sending seedlings. Since the seedlings used in the rice transplanter are blanket-like seedlings, the angle of sending seedlings is fixed each time, but the longitudinal sending distance cannot be guaranteed. Accurate in place, easy to accumulate errors after long-term continuous operation, it can still be used for blanket-shaped seedlings, but because pot seedlings are different from blanket-shaped seedlings, the distance between each pot is fixed, so the vertical delivery distance is required to be accurate, and should not occur Errors accumulate, otherwise the seedling tray will be damaged, and the quality of transplanting will decrease, and the seedlings should not move down on the seedling box due to the inertial force during the working process

Abstract

The invention relates to a longitudinal seedling-feeding mechanism for pot seedling transplanting, belonging to agricultural machinery. A rotating arm shaft seam is rotatably assembled on a side seedling box bracket; a locating rod is rotatably sleeved on the rotating arm shaft seam; a pull rod base is fixedly mounted on the rotating arm shaft seam; a pull rod is hinged on the pull rod base; one end of the pull rod is matched with the locating rod in an engaging or disengaging manner, and the other end of the pull rod is matched with a ratchet wheel in an engaging manner; a tension spring fixing base is arranged on the side seedling box bracket; two ends of a first tension spring are respectively connected to the pull rod and the tension spring fixing base; two ends of a second tension spring are respectively connected to the locating rod and the tension spring fixing base; the locating rod is matched with the ratchet wheel in an engaging or disengaging manner; and a push rod is hinged on the rotating arm shaft seam. As a ratchet wheel and connecting rod combined locking mechanism is adopted, accumulated errors during continuous pot seedling feeding operations are eliminated; and the longitudinal seedling-feeding mechanism has the characteristics of novel and reasonable structure design, good operation quality, no damage to a seedling tray, small operation fault and reliable use.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a vertical seedling delivery mechanism for pot seedling transplanting on a planting machine tool. Background technique [0002] Potted seedling transplanting has become the most direct mechanized planting method to increase grain production, and the corresponding supporting machinery is also gradually developing. The vertical seedling feeding mechanism for potted seedlings has become an important part of the seedling box. Most of the existing rice transplanter feeding mechanisms are ratchet mechanisms, all of which lack a locking mechanism for sending seedlings. Since the seedlings used in the rice transplanter are blanket-like seedlings, the angle of sending seedlings is fixed each time, but the longitudinal sending distance cannot be guaranteed. Accurate in place, easy to accumulate errors after long-term continuous operation, it can still be used for blanket-shaped seedlings, but...
