PATENT SPECIFICATION FOR THE INVENTIONENTITLED:

A quickly assembled and disassembled Sucking Disc for the Seed Picker

The invention is described in the following statement:-

A quickly assembled and disassembled Sucking Disc for the Seed Picker

TECHNICAL FIELD

The invention relates to the technical field of agricultural machinery and equipment, in particular to A quickly assembled and disassembled sucking disc for the seed picker.

BACKGROUND

Sowing is an important step in soybean production. Mechanization of soybean planting can not only improve productivity, save labor, but also improve production efficiency and increase production and income. Because the air suction seed picker can accommodate seeds of various sizes, that is, it doesn't need to be selected and graded, and has less damage to seeds, and it is easy to realize single-grain point sowing, which can greatly improve the operation speed of the seeder, so it has been widely studied and applied. Different sowing objects and planting modes have different requirements on the size of seed suction holes, the number of seeds per hole and the distance between holes. The adjustment of the existing air-suction soybean hole sowing machine is generally completed by replacing sucking discs and duckbill components with different numbers of seed suction holes and different apertures. Because the sucking discs are installed inside the hole sowing wheel, it is very troublesome to disassemble the parts to complete the replacement of the sucking discs. In addition, the current air suction hole sowing machine can not change the sowing number per hole, which is a big trouble for operators.

SUMMARY

In order to avoid the shortcomings of the prior art, the invention provides a quickly assembled and disassembled sucking disc for the seed picker, which can adjust the size and spacing of seed suction holes by quickly replacing different sucking discs according to the requirements of planting mode and seeding number, thus effectively realize the change of seeding number per hole and seeding hole spacing in the seeding process.

To solve the technical problems, the invention adopts the following technical scheme:

The invention relates to a quickly assembled and disassembled Sucking Disc for the Seed Picker, which has the following structural characteristics:

A sucking disc bracket (2) and an air chamber (1) are sleeved on a transmission shaft (4) of a seeder. The left side surface of the sucking disc bracket (2) is embedded in the air chamber (1), and the left side surface of which is attached to the concave surface of the air chamber (1), the right side surface is attached and connected with the end face of the arranged sucking disc (3).

Further, the sucking disc bracket (2) is composed of a bracket (21) and positioning pins (22), wherein the bracket (21) is in the shape of a steering wheel and is provided with four ribs, and the two positioning pins (22) are respectively arranged on the upper and lower thick ribs and one positioning pin (22) is respectively arranged on the left and right thin ribs.

Furthermore, the sucking disc (3) consists of a left part of sucking disc (31) and a right part of sucking disc (32), both of which are semicircular, and they are provided with seed sucking holes and positioning pin holes matched with the positioning pins (22), and the semicircular holes are arranged in the middle parts, so as to avoid the transmission shaft (4) during installation.

Beneficial effects:

1. The invention has simple and novel overall structure, simple and convenient operation, with less time and labor cost; It is suitable for precise seed taking of large seeds such as soybean, which can be quickly assembled and disassembled to realize seed taking adjustment. It broadens the application range of the sucking discs, improves the sowing quality, reduces the labor intensity and improves the sowing efficiency.

2. The invention adopts a sucking disc bracket structure, which consists of a bracket and a positioning pin, and the bracket is in the shape of a steering wheel, so that the weight of the sucking disc bracket is effectively reduced; and the positioning pins is matched with holes arranged on the sucking disc, so that the quick replacement of the sucking discs can be realized.

3. The sucking disc adopts a two-half structure, which ensures that the seed taking device can be replaced without detaching from the transmission shaft, thus effectively improving the replacement speed and the operation efficiency of the seeder.

DESCRIPTION OF THE INVENTION

The quick assembly and disassembly of a sucking disc for the seed picker has the following structural characteristics:

As shown in Fig. 1 and Fig. 2, a sucking disc bracket (2) and an air chamber (1) are sleeved on a transmission shaft (4) of a seeder. The left side surface of the sucking disc bracket (2) is embedded in the air chamber (1), and the left side surface of which is attached to the concave surface of the air chamber (1), the right side surface is attached and connected with the end face of the arranged sucking disc (3).

In specific implementation, as shown in Fig. 3, the sucking disc bracket (2) is composed of a bracket (21) and positioning pins (22), wherein the bracket (21) is in the shape of a steering wheel and is provided with four ribs, and the two positioning pins (22) are respectively arranged on the upper and lower thick ribs and one positioning pin (22) is respectively arranged on the left and right thin ribs.

As shown in Fig. 1 and Fig. 4, the sucking disc (3) consists of a left part of sucking disc (31) and a right part of sucking disc (32), both of which are semicircular, and they are provided with seed sucking holes and positioning pin holes matched with the positioning pins (22), and the semicircular holes are arranged in the middle parts, so as to avoid the transmission shaft (4) during installation.

Operation process:

Before sowing, the sucking disc bracket 2 and the air chamber 1 are sleeved on the transmission shaft 4 of the seeder. According to the requirements of planting agronomy and seed size, the selected sucking disc 3 is clamped on the positioning pin on the sucking disc bracket 2 by the positioning pin hole, so that it is attached to and fixed on the surface of the sucking disc bracket 2, and it can rotate along with the sucking disc bracket 2.

During sowing, with the operation of the seeder, negative pressure is formed in the cavity of the air chamber 1, seeds are adsorbed to the seed suction hole of the sucking disc under the action of negative pressure, and the adsorbed seeds are taken out of the seed chamber. When the seeds are transferred to the empty groove area at the lower part of the air chamber 1, the adsorbed seeds fall into the corresponding seed box at the lower end under the action of self-weight, thus realizing the seed taking process. In the operation process, the device can stop the seeder according to the requirements of planting mode and seeding number, pull out the left part of seed suction tray 31 and right part of seed suction tray 32 from the sucking disc bracket 2 in turn. Then select the left part of seed suction tray 31 and right part of seed suction tray 32 corresponding to the operation requirements to be respectively clamped on the positioning pin 22 of the sucking disc bracket 2 by the positioning pin holes, so as to quickly complete the replacement of the sucking discs , thereby realizing the adjustment of the number of sown grains and the distance between holes in the planting and sowing process of different varieties.
