Description

A socket-type wheat precision metering device

technical field

The utility model relates to a socket-type wheat precision metering device, which belongs to the field of agricultural machinery.

Background technique

Wheat is one of the main rations of the Chinese people, occupies an irreplaceable position in the dietary structure, and is also a very important commodity grain and trade grain. Reasonable and precise sowing can provide good growth conditions for wheat and improve the utilization efficiency of wheat on soil nutrition, water and sunlight, coordinate the relationship between wheat individuals and groups, make wheat earing rate high, grains are more and fuller, and realize wheat's fullness. High quality and high yield.

In actual production, the seed metering device for sowing wheat mostly adopts the outer groove wheel type seed metering device. The outer groove wheel type seed metering device is not a precision seed metering device. There is pulsation in the type seed metering device, which leads to lack of seedlings and broken ridges during the sowing process, or crowding of wheat seedlings, which greatly reduces the utilization rate of land resources.

Contents of the invention

The utility model provides a socket-type wheat precision seed metering device, which is used for realizing precise wheat sowing.

The technical scheme of the utility model is: a socket-type wheat precision metering device, including a seed box 1, a long hole 2, a cleaning brush 3, a socket 4, a seed guide partition 5, and a seed wheel 6. Seed protection board 7;

The seed box 1 is composed of a top surface and two sides. The four corners of the top surface of the seed box 1 are provided with elongated holes 2, and the screws pass through the elongated holes 2 to connect the seed box 1 with the seed box. 1 The middle opening of the top surface is provided with a seed guide partition 5 located directly below the seed box, the seed wheel 6 is inserted into the seed box 1 through the opening on the side of the seed box 1, and the seed wheel 6 wraps the seed protection plate 7 on both sides The surface circumference of the seed wheel 6 is provided with a socket 4 and the socket 4 is located between the seed guide partitions 5, and the top of the seed protection plate 7 on one side of the seed wheel 6 is provided with a cleaning brush 3, which is filled into the socket 4 With the rotation of the seeding wheel 6, the seeds will be cleared out of the socket 4 through the cleaning brush 3.

The shape of the cross-section of the socket 4 is a right-angled trapezoid (as shown in Figure 7), and the oblique waist surface is an open surface. Putting in one seed reduces missed seeding and replaying.

The described seed guide partition 5 is inverted V-shaped (as shown in Figure 5) on the longitudinal section, and the minimum distance n (as shown in Figure 5) between two adjacent seed guide partitions is smaller than the long axis size of the seed, so that the seed can only It can be arranged parallel to the seed guide partition according to its long axis direction, assists in seed filling, improves seed filling speed, and reduces missed sowing of seeds.

The working principle of the utility model is:

The seeds in the seed box fall into the seed box 1, and the seeds are filled into the socket 4 in the specified direction under the guidance of the seed guide partition 5, and the seeds filled in the socket 4 pass through the seed cleaning process with the rotation of the seed wheel 6. Hairbrush 3, seed cleaning brush 3 clears redundant seeds out of socket 4, ensures that only one seed is filled in each socket 4, and the seeds continue to rotate with the seeding wheel 6, under the protection of the seed protection plate 7 , the seeds will not break away from the socket 4, and the seeds will break away from the socket 4 under the action of gravity after the seeds turn away from the area protected by the seed protection plate 7, and fall into the soil to complete the entire seeding process.

The beneficial effects of the utility model are: it solves the phenomenon of uneven seeding, lack of seedlings and broken ridges of the existing wheat seed metering device; it can realize precise sowing of wheat, save seeds, and improve resource utilization; the seed guide partition is designed, Improve the filling speed of seeds and reduce the rate of missed sowing; the sockets are designed in a right-angled trapezoidal shape, which is easy to fill and clear seeds; simple structure, convenient operation, and stable work.
