Abstract
Description
Technical Field
[0001] This utility model relates to the field of seeder technology, and in particular to a compact fertilizer box for a precision grain seeder. Background Technology
[0002] like Figure 1 As shown, the fertilizer box structure of most precision grain seeders currently used in the market is a double crossbeam support frame 1 at the bottom, which occupies a large space at the front and back. This results in the overall center of gravity of the seeder being at the rear. In addition, the seeder becomes quite heavy when it is full of seeds and fertilizer, which increases the horsepower of the tractor or makes it impossible for the tractor to carry the seeder. This makes the seeder less adaptable and is not conducive to its promotion and application.
[0003] Therefore, there is a need for a compact fertilizer box for precision grain seeders that solves the above problems. Utility Model Content
[0004] This utility model proposes a compact fertilizer box for a precision grain seeder, which shortens the distance between the fertilizer box and the seeder and the traction frame, thereby making the overall structure of the seeder more compact and the center of gravity closer to the traction frame, making the seeder easier to carry, and thus improving the applicability and operating efficiency of the precision grain seeder.
[0005] The technical solution of this utility model is implemented as follows:
[0006] A compact fertilizer box for a precision grain seeder includes two symmetrically arranged single crossbeam mounting frames. Each single crossbeam mounting frame has a fertilizer box mounted on it. Each single crossbeam mounting frame includes a first support crossbeam and a second support crossbeam. The seeder has a main beam, which is positioned between the first and second support crossbeams. Each first and second support crossbeam is positioned above the main beam. A pair of first support arms are provided between each first support crossbeam and the main beam. A second support arm is provided between the beam and the main beam of the seeder. A traction frame for suspending the drive device is installed on the main beam of the seeder. The traction frame includes a horizontally arranged traction beam. Two second support beams are arranged between the main beam of the seeder and the traction beam. The main beam of the seeder, the two first support beams, the two second support beams and the traction beam are arranged in parallel. A fertilizer box is installed on the corresponding first support beam, the corresponding second support beam and the traction beam. The two fertilizer boxes are symmetrically arranged above the main beam of the seeder.
[0007] As a preferred technical solution, a first support side plate is fixedly installed on the outer side wall of each fertilizer box near the seeder, and the free end of each first support side plate is installed on the corresponding first support crossbeam.
[0008] As a preferred technical solution, a second support side plate is fixedly installed on the outer side wall of each fertilizer box near the traction beam, and the free end of each second support side plate is installed on the traction beam.
[0009] As a preferred technical solution, a first support end plate is fixedly installed on the outer side wall of each fertilizer box away from the other fertilizer box, and the free end of each first support end plate is installed on the corresponding first support beam and the corresponding second support beam.
[0010] As a preferred technical solution, a second support end plate is fixedly installed on the outer side wall of each fertilizer box near the other fertilizer box, and the free end of each second support end plate is installed on the corresponding first support beam and the traction beam.
[0011] By adopting the above technical solution, the beneficial effects of this utility model are as follows:
[0012] Because the compact fertilizer box used in the precision grain seeder includes a single crossbeam mounting frame, one end of the fertilizer box forms a stable triangular connection through the seeder main beam, first support arm, first crossbeam, first support end plate, second crossbeam, and second support arm. The other end of the fertilizer box forms a stable triangular connection through the seeder main beam, first support arm, first support crossbeam, second support side plate, and traction frame. The two sides of the fertilizer box are respectively installed on the first support crossbeam and traction crossbeam through the first support side plate and the second support side plate, thus making the installation of the fertilizer box more stable. At the same time, compared with the double crossbeam support used in traditional seeders, the first crossbeam, second crossbeam, and traction crossbeam used to support the fertilizer box in this utility model are all compactly installed on the seeder main beam, thus completing the installation of the fertilizer box in a smaller space, shortening the distance between the fertilizer box and the seeder and traction frame, making the overall structure of the seeder more compact, and the center of gravity closer to the traction frame, making the seeder easier to carry during use, making the precision grain seeder more versatile, and improving the working efficiency of the seeder while ensuring the seeding quality.
