Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco transplanters, in particular to a combined well-pit tobacco seedling transplanter. Background Art
[0002] Guizhou Province in my country has a distinct three-dimensional climate. Most tobacco-growing areas experience low temperatures and limited sunlight during the seedling-raising period from January to March. By the time the optimal transplanting period for flue-cured tobacco arrives, it's difficult to cultivate tall, strong seedlings. Transplanting is often delayed or weak seedlings are transplanted, failing to ensure the tobacco plants receive optimal temperature, light, and water conditions for growth and development. Later in the season, the tobacco plant is susceptible to summer drought, resulting in low yield and quality, and a lack of full expression of its distinctive characteristics. Tobacco production in Guizhou must proceed early, ensuring that transplanting is completed by the end of April. This allows the optimal growing season to occur between May and June, avoiding the effects of the late summer drought. Therefore, the "well-cellar transplanting technology" was invented in this context and has been well promoted. The "well-cellar transplanting technology" is a transplanting method that transplants seedlings into a well-cellar of a certain specification under the ridge body, realizing the cultivation of strong seedlings, timely early planting, and high ridge and deep planting in the well-cellar at the same time, ensuring that the tobacco plants are in the best temperature, light and water in May and June for vigorous growth; for tobacco seedling transplanting, well-cellar transplanting is currently a more advanced tobacco transplanting method, which has many advantages compared to other transplanting methods: such as achieving consistent tobacco growth quality, high survival rate, reducing costs, and increasing production and income.
[0003] The well pits in the traditional "well pit transplanting technology" require a single person to walk and hold a well pit maker to make holes, and other personnel follow to perform operations such as planting seedlings and adding water. This is time-consuming and labor-intensive, increases the workload of workers, and has low work efficiency. Therefore, it is necessary to develop a tobacco transplanter with a continuous tracking well pit digging method, using automated machines to replace manual labor, and only using one transplanter to realize the integration of well pit digging, transplanting and watering, thereby improving work efficiency. However, most of the well pit transplanters currently use a stop-and-go well digging operation. The machine stops when it drives to the well digging position. The well pit digging device and the seedling planting device are separately set as two devices, and the seedling planting device is sometimes divided into an upper seedling planting device and a lower seedling planting device. The structure is relatively complex, which increases production costs. In order to simplify the structure and reduce production costs, a tobacco transplanter is developed to combine the well pit digging device and the seedling planting device to work in conjunction.

[0031] In summary, the working principle of the above embodiment is as follows: the tobacco transplanter of the continuous tracking well-drilling cellar is operated by an operator who places the tobacco seedling hole tray on the seedling tray bracket 4 and starts the machine. The generator 2 provides power for the whole machine, and the transmission motor 1-5 drives the transmission 1-3 to work through the belt 1-4. The transmission 1-3 drives the drive shaft and the crawler drive wheel 1-2 to rotate. With the cooperation of the gear lever, the straight-line driving operation of the chassis of the whole machine is realized, and the speed gear can be adjusted according to different working and driving conditions. When the crawler-type walking chassis 1 of the transplanter moves forward on the ridge surface, the crawler-type walking chassis 1 moves, and the transplanter stops walking every time it passes a distance of 550mm. The well-drilling up and down moving module 8-1 is driven by the servo motor 8-4 up and down when drilling wells. Under the action of the movement, the two drilling bits 8-3 are moved downward by driving the punching movable plate 8-2. At the same time, the two drilling bits 8-3 are rotated by the DC brushless motor 8-5 and contact the ridge surface to complete the well cellar work. After the well cellar is dug, the horizontal moving module 7-4 is driven by the horizontal servo motor 7-9 and moves on the horizontal moving module 7-4 through the left and right horizontal moving plates 7-6. The moving distance is the distance between the guide tube 9-3 and the drilling bit 8-3. The seedling throwing up and down moving module 9-1 is driven by the seedling throwing up and down servo motor 9-4, so that the two guide tubes 9-3 are driven by the seedling throwing movable plate 9-2 to move above the well cellar. The cover under the guide tube 9-3 opens, and the tobacco seedlings fall into the well cellar, completing the seedling throwing work. After the seedling tray is finished, the operator changes the tray to meet the seedling throwing operation and ensure the continuity of the whole machine work process.
