Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of agricultural engineering, in particular to a large-diameter air suction seed metering device cast steel monomer. Background Art
[0002] An air suction seed meter is an agricultural mechanical device that uses airflow to sow seeds. It absorbs seeds through negative pressure air and accurately controls the discharge of seeds through a specific seeding disc structure. It is suitable for sowing operations of various crops. In traditional air suction monomers, there are cases where the seeding disc diameter is small or the monomer is a frame welded structure. These structural designs bring many defects. Taking the small seeding disc diameter as an example, due to the small seeding disc diameter, the number of seed suction holes must be small, which requires a higher number of revolutions to meet the sowing requirements during sowing operations. The high number of revolutions brings a series of side effects. First, the sowing accuracy is low, and it is difficult to accurately perform sowing operations according to the predetermined requirements. Secondly, the high number of revolutions will cause accelerated wear of various components, thereby reducing the service life. This not only increases the maintenance cost of the equipment, but also affects the continuity and stability of the sowing operation. For welded monomers, it is a one-time molding structure. This structure results in poor accuracy, and it is difficult to accurately control parameters such as sowing amount and sowing position during the sowing process. Utility Model Content
[0003] In order to overcome the above-mentioned defects, the utility model provides a large-diameter air suction seed metering device cast steel unit, which solves the problem that in traditional air suction units, due to the small diameter of the seeding disc, a higher number of revolutions is required to meet the seeding requirements during seeding operations, and then the high number of revolutions has low seeding accuracy. At the same time, the high number of revolutions will cause accelerated wear of various components, thereby reducing the service life.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a large-diameter air suction seed metering device cast steel body, including a body bracket, one side of the body bracket is rotatably connected to a sowing disc, the outer wall of the sowing disc is provided with a V-shaped groove, the end of the body bracket is fixedly connected to a guide piece, the position of the guide piece is located on one side of the sowing disc, the other side of the sowing disc is provided with a paddle, one end of the paddle is fixed to one side of the sowing disc, a slot is provided on the top of the body bracket, the end of the body bracket is fixedly connected to a traction frame, and one side of the traction frame is rotatably connected to a rotating gear.
[0005] As a further solution of the present invention: a sowing box is provided above the single-body bracket, a supporting bracket is fixedly connected below the sowing box, and the supporting bracket is fixedly connected to the top of the single-body bracket by bolts.
[0006] As a further solution of the present invention: a vertical bar is fixedly connected to one side of the support bracket below the seeding box, and the position of the vertical bar corresponds to the position of the card slot.
[0007] As a further solution of the present invention: a negative pressure fan is provided below the seeding box, and the negative pressure fan is located between the supporting bracket and the vertical bar.
[0008] As a further solution of the present invention: two protective shells are respectively provided on both sides of the seeding box, and the two protective shells are fixedly connected to the two sides of the seeding box by bolts, and one of the protective shells is fixedly connected to the negative pressure fan by bolts.
[0009] As a further solution of the present invention: a fertilizer box is provided on one side of the sowing box, the fertilizer box is fixedly connected between the two protective shells by bolts, and a discharge port is provided below the fertilizer box.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] 1. The large-diameter air-suction seed metering device is a cast steel monomer. By setting a monomer bracket, a traction frame and a sowing disc, during use, the monomer bracket is driven by the traction frame to move for sowing. During the sowing process, due to the large diameter of the sowing disc and the large number of seed suction holes on the sowing disc, the rotation speed of the sowing disc is reduced during the sowing process, which reduces the wear of the sowing disc during the sowing process. At the same time, due to the large number of seed suction holes on the sowing disc, the sowing accuracy is improved, and the sowing requirements can be accurately met with high efficiency, thereby achieving the effect of increasing production and income.
[0012] 2. The large-diameter air suction seed metering device is a cast steel monomer. By setting a support bracket, a vertical bar, a monomer bracket and a slot, the vertical bar is inserted into the slot above the monomer bracket, and the support bracket is fixedly connected to the top of the monomer bracket by bolts. It abandons the traditional monomer forming method of one-time welding. Through high-precision casting and high-precision processing, it is not easy to deform, thereby improving the structural strength of the monomer and ensuring the service life.

The negative pressure fan 12 is located between the support bracket 10 and the vertical bar 11. Two protective shells 13 are provided on both sides of the sowing box 9. Because of the protective shell 13, the protective shell 13 can prevent external debris from entering the sowing box 9 and the negative pressure fan 12, which helps to maintain the normal working state of the negative pressure fan 12 and ensure the stability of the suction of the negative pressure fan 12, thereby improving the sowing efficiency.
