This invention belongs to a seedling separating device based on a rack and pinion drive in the field of transplanting machine in the agricultural automation facility, including a rack, a power unit, a linear drive, a number of seedling cups and a cylinder pushing device. The linear actuator is driven by the power unit to move on the frame; these seedling cups are mounted on the linear drive; the cylinder pushing device is mounted on the frame and is located behind the seedling cups and it drives the lower part of the seedling cup to open and retracts to close. The seedling device has simple structure, controllable program and high reliability. The motor drives the seedlings cups to move left and right; the cylinder pushes the cups to be opened and closed; the trust cup is straight down, the seedling attitude is better and the location of seedling can also be adjusted. The device can not only achieve the exact location in the designated seedling, but also to achieve the seedling movement of separating seedlings to two points from the mouth of the seedling cups.
Description
technical field [0001] The invention belongs to the field of seedling separation by transplanting machines in agricultural automation facilities, and in particular relates to a seedling separation device based on rack and pinion transmission. Background technique [0002] At present, mechanized transplanting has been greatly developed, and there are many kinds of transplanting machines with various functions. But it is generally a general-purpose transplanting machine. Since there are certain differences in the size and physical characteristics of various vegetable seedlings, the planting requirements such as row spacing, plant spacing, and the number of rows planted on the same ridge are also different. The general-purpose transplanting machine is widely used in various types of vegetable fields in my country. Has a certain degree of difficulty. From the initial seedling cultivation to transplanting of plug seedlings, there is a lot of repetitive labor in the middle. Conti...
