Plug seedling plantation driving mechanism

Abstract

The invention discloses a plug seedling plantation driving mechanism, which comprises a frame and a crank. The crank is connected to one end of a first connecting rod to form a rotation pair. The first connecting rod is connected to a rocking bar to form a rotation pair. The tail end of the rocking bar is connected to a slide block through a second connecting rod. The slide block is arranged in aslide rail, which is hinged to the frame. At the same time, the slide block, a third connecting rod, and a fourth connecting rod are connected to each other to form a rotation pair. The third connecting rod and the fourth connecting rod are respectively connected to a first arm rod and a first elbow rod to form a rotation pair. One end of the first arm rod, one end of the first elbow rod, and oneend of a fifth connecting rod are connected to each other. The other end of the fifth connecting rod, a second arm rod, and a second elbow rod are connected to each other. The tail ends of the first arm rod and the second arm rod are connected to a suspended cup. Through the arm rods parallel to each other, elbow rods parallel to each other, and swinging slide rail, the suspended cup is erected, and the size of punched holes is reduced. Based on the quick-return characteristics of the crank-rocking bar structure, the plantation and cup-pulling speed is reasonably set, and high speed plantationis realized.

Description

technical field [0001] The present invention relates to agricultural machinery, in particular to a plug seedling planting mechanism; specifically, it is suitable for single-hanging cup operation and meets the needs of fully automatic single-row plug seedling film transplanting operations with small holes and reduced film tearing. A plug seedling planting driving mechanism according to the requirements of the utility model. Background technique [0002] With the continuous improvement of living standards, people's demand for vegetables continues to increase. Vegetable transplanting takes a long time and is labor-intensive. The biggest problem at present is the shortage of labor force and low production efficiency. Therefore, under the urgent need of insufficient and aging manpower, improving operating efficiency and reducing production and marketing costs, mechanization of vegetable planting has become an urgent need, and mechanization of vegetable production has become an i...

Problems solved by technology

Plastic film technology is widely used in my country, but the planting effect on the film of the existing transplanting machinery is generally not good, mainly because the track of the planting mechanism is composed of the forward movement of the transplanting machine and the movement of the planting mechanism itself. When the forward speed of the planter and the distance between plants change, the trajectory of the hole-making seedlings will change accordingly, and the horizontal speed cannot be guaranteed to be zero during the hole-making stage.

Many experts and scholars at home and abroad have done a lot of research work in the field of automatic vegetable transplanting, but there has been no effective breakthrough in the problems of low planting efficiency on film and duckbill stripping.
