Description

Technical Field

[0001] The utility model relates to the technical field of rice transplanters, in particular to a fully hydraulically driven riding high-speed rice transplanter. Background Art

[0002] With the continuous development of agricultural technology, the planting technology of rice fields has also been greatly improved. Agricultural mechanization has continuously replaced the traditional pure manual work, which has greatly improved production efficiency. For example, the transplanting work that previously required several people to spend half a day to complete can be completed in just a dozen minutes using a transplanter. A transplanter is an agricultural machine that implants rice seedlings into rice fields. The working principle of a transplanter is as follows: when planting rice seedlings, first place the rice seedlings on the transplanting platform. The transplanting platform has a walking mechanism or moves forward under the drive of the drive unit. At the same time, the mechanical claw takes out several rice seedlings from one side of the transplanting platform and inserts them into the soil below. Each time the transplanting platform moves a predetermined distance, the mechanical claw completes a transplanting operation. The transplanter can be divided into a low-speed transplanter and a high-speed transplanter according to the transplanting speed, and can be divided into a walking transplanter and a riding transplanter according to the operation mode of the transplanter. Generally, a transplanter consists of a drive unit and a transplanting unit. The connection between the drive unit and the transplanting unit can be hydraulically driven or electrically driven.

[0003] In the prior art, the rice transplanter has the following problems: when the mechanical claw takes out several seedlings from one side of the transplanting platform and inserts them into the soil, the seedlings are located in the V-shaped groove of the mechanical claw. The force of the seedling pushing plate to push the seedlings out of the V-shaped groove is determined by the size of the spring force. When the soil is uneven, the push stroke of the seedling pushing plate will be inconsistent, resulting in some seedlings not being implanted deep enough in the soil, affecting the transplanting effect.
