Front-installed vegetable and oilseed rape transplanter

Abstract

The invention discloses a front-installed vegetable and oilseed rape transplanter. According to the front-installed vegetable and oilseed rape transplanter, a transplanting mechanism is installed at the front part, while an engine is installed at the rear part. The transplanter is driven in a riding way, and a steering machine is controlled by a steering wheel to steer. Both the steering wheel and a seedling feeding cup are arranged at the front end of the transplanter; since seedling feeding and driving can be performed by only one person, the production efficiency is enhanced. The transplanter is provided with a hydraulic automatic profiling mechanism; when the change of ridge height or transplanter sinking depth causes the change of transplanting depth, the profiling mechanism performs correction automatically, so that a transplanter body or transplanting clamps can automatically ascend or descend and consequently the condition that the seedling transplanting depth is always the same can be ensured. Due to the design of a special gear and tooth column structure, the steering of front wheels of the transplanter and the automatic ascending or descending adjustment on a transplanter body can be performed simultaneously. The transplanting mechanism is composed of a cleverly evolved crank-rocker mechanism and an eccentric wheel compensation mechanism by which the transplanting clamps are jointly controlled to move, so that the work of seedling transplanting is finished.

Description

technical field [0001] The invention relates to a vegetable and rapeseed transplanting machine with a transplanting mechanism in front. technical background [0002] At present, in vegetable and rapeseed seedling transplanting machines, there are mainly two structural forms of the machine: one is the trailer type, the transplanting machine itself has no power, and it is matched with a tractor, and the tractor carries out the hanging and towing operation; It is a walk-behind transplanting machine with its own power. Although this kind of transplanting machine has its own power, it is operated by the handle, and the working people walk randomly to carry out the driving operation. The first type of trailer-mounted transplanter is generally used in conjunction with large and medium-sized tractors. It has high efficiency, but it also consumes a lot of manpower. The driving and seedling operations are completed by different personnel, one person drives full-time, and the other per...

Problems solved by technology

However, the rear transplanting mechanism of the hand-held transplanter on the market still has two defects: one is that the labor intensity is too high, one person walks hand-held, people walk randomly, the labor intensity is high, and at the same time, the machine must be operated while driving. After completing the seedling setting operation, you can’t take care of it if you don’t pay attention, so it is easy to miss planting; second, when the machine is turned, because it is operated by the handle, it is necessary to manually lift the front body and front wheels of the machine to make the body turn, and the operation intensity is very high.

The transplanting mechanism is placed at the rear, and it is impossible to realize that the driving on the machine and the work of putting seedlings can be completed by one person at the same time, because the driver faces the front, while the work of putting seedlings is at the rear of the machine, and the two cannot be taken care of at the same time
