Description

Technical Field

[0001] This utility model relates to a seeder, specifically to a main suspension arm structure for a seeder. Background Technology

[0002] The seeder suspension arm is the component connecting the seeder to the tractor. The tractor drives the seeder (or integrated seeder and fertilizer applicator) to sow crops via the traction of the seeder suspension arm. Currently, one end of the seeder suspension arm has two lugs connected to the tractor's traction part via pins, while the other end is fixed to the seeder with bolts. Because the two lugs are parallel, the seeder tends to sway left and right during operation, causing the seed rows to bend and become crooked. Furthermore, the connection between the seeder suspension arm and the seeder is not flexible enough, and connecting and disconnecting them is time-consuming and laborious. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a main suspension arm structure for a seeder, which prevents the seeder from swaying left and right when driven by the main suspension arm structure, and the connection between the main suspension arm and the suspension frame of the seeder is convenient and firm.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a main suspension arm structure for a seeder, including a main suspension arm, the two sides of the main suspension arm are inclined upward and inward in a trapezoidal structure, the rear half of the two sides of the main suspension arm is connected to the main beam of the seeder, and the front part of the main suspension arm is connected to the three-point suspension of the tractor.

[0005] The upper part of the rear half of both sides of the main suspension arm forms a 45° angle with the upper part of the seeder beam. The lower part of the rear half of both sides of the main suspension arm is a right-angle structure. Bolts are installed on the lower part of the rear half of both sides of the main suspension arm. Each bolt is fixed with a locking block at the end of the seeder beam. The upper part of the locking block is similar to the lower part of the seeder beam. A locking nut is provided on the other end of each bolt.

[0006] The main suspension arm structure of the seeder designed using the above-mentioned technical solution has a trapezoidal structure with its two sides inclined upward and inward. The lower part of the main suspension arm is firmly in contact with the main beam of the seeder, which makes the seeder more stable during operation and prevents it from swaying, thus facilitating sowing. Furthermore, the main suspension arm and the main beam of the seeder can be easily fixed and separated, making operation simple and convenient. Attached Figure Description

[0011] The main suspension arm structure of the seeder of this utility model will be described in detail below with reference to the accompanying drawings.

[0012] This utility model relates to the main suspension arm structure of the seeder. See [reference needed]. Figures 1 to 4 The system includes a main suspension arm 2, which has a trapezoidal structure with both sides inclined upwards and inwards. The front part of the main suspension arm 2 is connected to the tractor's three-point suspension. Specifically, two lugs 3 are provided on the upper front part of the main suspension arm 2, and each lug 3 has a pin hole 4. Pins 5 are respectively provided on both sides of the lower front part of the main suspension arm 2. When connecting the main suspension arm 2 to the tractor's three-point suspension, the two lugs 3 and the two pins 5 are connected to the corresponding parts of the tractor's three-point suspension.

[0013] The rear half of both sides of the main suspension arm 2 is connected to the seeder beam 1. Specifically, the upper part of the rear half of both sides of the main suspension arm 2 forms a 45° angle with the upper part of the seeder beam 1. The lower part of the rear half of both sides of the main suspension arm 2 is a right-angle structure. Bolts 6 are installed on the lower part of the rear half of both sides of the main suspension arm 2. Each bolt 6 is located at the end of the seeder beam 1 and a locking block 7 is fixed thereon. The upper part of the locking block 7 is similar to the lower part of the seeder beam 1. A locking nut is provided on the other end of each bolt 6.

[0014] During connection, place the upper rear half of both sides of the main suspension arm 2 onto the seeder beam 1. Rotate the locking nut on the bolt 6 to make the locking block 7 press against the lower part of the seeder beam 1, thus firmly connecting the main suspension arm 2 and the seeder beam 1 together. Rotate the locking nut on the bolt 6 in the opposite direction to separate the locking block 7 from the seeder beam 1. After removing the bolt 6, the main suspension arm 2 can be separated from the seeder beam 1.

[0015] Because the main suspension arm 2 of the seeder has a trapezoidal structure with its two sides tilted upwards, the distance between the lower part of the main suspension arm 2 and the contact point of the seeder beam 1 is large, which makes the traction of the seeder more stable during operation and prevents the seeder from swaying, thus facilitating sowing.
