Description

The main frame of the trailed two-row no-tillage planter

technical field

The utility model belongs to the technical field of seeders and relates to a main frame of a traction type two-row no-tillage seeder.

Background technique

At present, the two sowing units of the traction type two-row no-tillage planter are fixed on the front suspension frame. It is easy to cause the body to tilt, so that the sowing depth of the two rows is different. If the seeding is too deep, the emergence will be delayed, the seedlings will be thin, the rhizomes or hypocotyls will be elongated, and the root system will be underdeveloped; if the seeding is too shallow, the topsoil will dry easily, and the seeds will not germinate smoothly, resulting in lack of seedlings and broken ridges. Therefore, whether the sowing depth is appropriate or not directly affects the growth and yield of crops.

Contents of the invention

The technical problem to be solved by the utility model is to provide a main frame of a traction-type two-row no-tillage planter with the same sowing depth so as to ensure the quality and yield of crop growth and development.

In order to solve the above-mentioned technical problems, the main frame of the traction type two-row no-tillage planter of the present invention includes a traction frame, a crossbeam, a rear suspension frame, a fixed bracket, a support shaft, a connecting frame, a support lever, and a driving mechanism; the traction frame The front end of the tractor is hinged with the tractor, and the rear end is fixedly connected with the girder; the rear suspension frame is fixed behind the girder; the two fixed brackets are located under the girder, and the two ends of the support shaft are respectively fixedly connected with the connecting frame, and the connecting frame is connected with the planter The rotating shafts of the walking wheels are connected; the supporting shaft is supported by two fixed brackets and can rotate relative to the two fixed brackets; the supporting shaft is fixed with a supporting lever, and the end of the lever is connected with the driving mechanism installed on the traction frame.

When there is no need for sowing operations, the support lever is positioned above the support shaft under the action of the drive mechanism, and the girder is lifted away from the ground by the support lever, so that the two sowing units fixed on the rear suspension frame are kept away from the ground. The main frame is towed and walked by a tractor. When the sowing operation is required, the driving mechanism removes the force acting on the support lever, and the support lever rotates downward together with the support shaft to make the girder and the traction frame fall, so that the two sowing units fall at the same time for sowing. Since the two sowing units move up and down with the girder for the same distance, the same depth of sowing can be ensured, thereby ensuring the quality and yield of crop growth and development.

The traction frame is composed of an integrated main draw bar and two draw struts, the front end of the main draw bar is hinged to the tractor, the rear end is connected to the front ends of the two draw struts, and the rear end of the two draw struts is connected to the The girder is fixedly connected.

The driving mechanism includes a hydraulic mechanism and a bumper; the hydraulic cylinder of the hydraulic mechanism is movably connected with the traction frame, the piston rod of the hydraulic mechanism is connected with one end of the bumper, and the other end of the bumper is hinged with the end of the support lever.

The utility model may also include a front suspension frame: the front suspension frame is fixedly connected with the girder and the traction frame, and the front suspension frame is fixed with a connecting frame for cutting and fertilizing knives.

The utility model can also include a fertilizer box frame; the fertilizer box frame is fixed on the girder.
