Description

Connecting device of forest planting seeder Technical Field The utility model relates to the field of seeders, in particular to a connecting device of a forest planting seeder. Background The forest planting seeder is a special agricultural machine for forestry, has the main functions of seeding operation in a forest land for sowing tree seeds, is designed to improve the seeding efficiency, ensure the seeding quality, and reducing the manual labor intensity, the connection device of the forest planting seeder generally refers to a part for connecting the seeder with a traction vehicle (such as a tractor) so that the seeder can work in the field. While conventional forest seeder connection devices are typically of a fixed length, for different models or sizes of tractors, the connection devices need to be customized or replaced, adding to the inconvenience and cost of use. Accordingly, a person skilled in the art provides a connection device for a forest planting machine to solve the above-mentioned problems in the background art. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides a connecting device of a forest planting machine, which is characterized in that a first bolt is rotated to leave a first threaded hole, the position of a telescopic plate is adjusted, the first bolt is screwed down again to be fixed after positioning, so that the height of a device is adjusted, and then the device is firmly installed on a tractor by a fixing mechanism, so that the device can adapt to the tractors with different heights, ensure stable connection, reduce jolt operation and improve stability and comfort level. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a forest planting seeder connecting device, includes connecting block and fixed establishment, and flexible connecting block front end is provided with telescopic machanism, fixed establishment is located telescopic machanism front end, telescopic machanism includes the mounting panel, the mounting panel inner wall is provided with the expansion plate, a plurality of first screw holes have all been seted up to mounting panel and expansion plate upper end, and a plurality of first screw hole inner wall is provided with first bolt, connecting block front end fixedly connected with a plurality of first articulated blocks, both sides first articulated block front end rotates and is connected with the telescopic link, expansion plate and two telescopic link front ends all rotate and are connected with the second articulated block; Through above-mentioned technical scheme, rotatory first bolt makes it break away from first screw hole, adjusts the position of expansion plate at the mounting panel inner wall, adjusts to suitable position, just screws in first screw hole again with first bolt, fixes to this adjusting device height, the tractor of device adaptable not co-altitude.
