The invention discloses a planting distance speed adjustment mechanism for a rice transplanter. The planting distance speed adjustment mechanism comprises a gear shaft, a gear group mounted on the gear shaft, a gear speed adjustment shaft and a gear shift lock device matched with the gear speed adjustment shaft, wherein a speed adjustment cavity is formed in the gear shaft; the gear speed adjustment shaft is inserted in the speed adjustment cavity; the gear shaft is provided with steel ball mounting holes as many as gears of the gear group and are communicated with the speed adjustment cavity; steel balls are arranged in the steel ball mounting holes; a gear shift working head for pushing the steel balls out of the steel ball mounting holes is fixed at the end part, inserted into the speed adjustment cavity, of the gear speed adjustment shaft; the gears of the gear group are provided with clamping holes matched with the steel balls. The planting distance speed adjustment mechanism is simple in structure, small in size, light in weight and easy to manufacture, process and assemble, and soft in speed change; the gear breakage phenomenon cannot be caused in a using process; the gears cannot be damaged.
Description
technical field [0001] The invention relates to the technical field of rice transplanters, and more specifically relates to a plant-to-plant speed regulating mechanism for rice transplanters. Background technique [0002] Rice is one of the major industries supporting the lifeline of China's agriculture. In recent years, with the rapid development of high-yield and high-quality rice varieties, my country's grain output has continued to increase, and the mechanization level of high-number rice transplanters has made significant progress. Rice transplanters are becoming more and more humanized and intelligent. Determine the plant spacing of seedlings according to actual conditions to obtain better yields. For example, the Chinese utility model patent whose patent publication number is CN201601969U and whose publication date is 2010.10. A component, a tower gear set, a positioning mechanism, a positioning plate and a speed regulating rod; a positioning mechanism is installed on ...
