Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to an air-transported wheat ridgeless seeding machine. Background Art

[0002] Wheat planting in my country is mainly based on narrow ridge sowing, with a ridge spacing of 12 to 15 cm and a sowing depth of about 2 cm. Some areas now implement wide seedling strip sowing, evenly spreading seeds on a relatively wide sowing belt, increasing the area occupied by a single seed, promoting nutrient absorption by the plant, and thus achieving the goal of high yield. Extending on this technology, ridgeless uniform sowing of wheat has been introduced, changing the original strip sowing to broadcast sowing, without forming ridges on the surface, maximizing the area occupied by a single seed and achieving high grain yields.

[0003] The key technical point of ridgeless uniform sowing is that the seeds can be sown evenly. At present, this technology is realized by discharging the seeds in the seed box from the seed meter and relying on their own gravity to hit a guide plate. The seeds are scattered by the impact force and then fall to the ground. The seeds sown solely by the guide plate have too random particle spacing and are difficult to control, and cannot achieve the ideal uniform sowing state. Utility Model Content

[0004] In order to solve the above problems, the present invention adopts the following technical solutions:

[0005] An air-conveyed wheat ridgeless seeder, comprising:

[0006] A seed box connected to the frame;

[0007] A seed metering device is provided at the outlet of the seed box; the outlet of the seed box is connected to a seed conveying main pipe;

[0008] A fan, wherein the outlet of the fan, the outlet of the seed metering device, and the inlet of the seed conveying main pipe are connected to form a three-way structure;

[0009] A seed distributor, the inlet of the seed distributor is connected to the outlet of the seed delivery main pipe; the outlet of the seed distributor is connected to a seed delivery branch pipe; the outlet of the seed delivery branch pipe is connected to a seed delivery tail pipe, so as to evenly sow the wheat seeds on the seed bed.

[0010] Furthermore, the inlet of the seed delivery tail pipe is connected to the outlet of the seed delivery branch pipe, and the outlet of the seed delivery tail pipe extends toward the seed bed and is suspended above the seed bed.

[0011] Furthermore, the seed distributor is provided with a plurality of outlets; the inlets of the plurality of delivery branch pipes are connected to the outlets of the plurality of seed distributors in a one-to-one correspondence.

[0012] Furthermore, a plurality of seed delivery tail pipes are provided; the inlets of the plurality of seed delivery tail pipes are connected to the outlets of the plurality of seed delivery branch pipes in a one-to-one correspondence.

[0013] Furthermore, the plurality of seed conveying tail pipes are arranged linearly.

[0014] Furthermore, the outlet end of the seed conveying tail pipe is in a flat trumpet shape.

[0015] Beneficial effects:

[0016] The utility model provides an air-conveyed wheat ridgeless uniform seeder, which generates airflow through the rotation of a fan and blows the air into a seed conveying main pipe. The seeds discharged by the seed meter are mixed with pressurized gas in the seed conveying main pipe and are conveyed to the seed distributor under the action of the airflow. The seed distributor can evenly distribute the seeds entrained in the airflow to each seed delivery branch pipe to reach the end of the seed delivery tail pipe. The seeds fill the flat outlet at the end of the seed delivery tail pipe under the action of the airflow, are further dispersed, and are evenly scattered onto the seed bed. Since the seeds are conveyed with pressurized airflow throughout the entire process and are evenly distributed by the seed distributor, more even sowing can be achieved. A number of tail pipes are provided according to the sowing width and are linearly distributed. There is no interval between the seed delivery tail pipes, so as to achieve ridgeless sowing.

[0033] In this embodiment, the inlet of the seed delivery tail pipe 7 is connected to the outlet of the seed delivery branch pipe 6 , and the outlet of the seed delivery tail pipe 7 extends toward the seed bed and is suspended above the seed bed.

[0034] Among them, one end of the seed conveying tail pipe 7 close to the outlet of the seed conveying tail pipe 7 can be rotated at an adjustable angle around the outlet of the seed conveying branch pipe 6. By rotating the outlet end of the seed conveying tail pipe 7, the angle between the horizontal plane where the outlet of the seed conveying tail pipe 7 is located and the ground plane is adjusted to achieve precise control of the seed spacing.

[0035] Through the above technical solution, the connection between the inlet of the seed delivery tail pipe 7 and the outlet of the seed delivery branch pipe 6 is set as the first connection, and the end of the seed delivery tail pipe 7 away from the inlet of the seed delivery tail pipe 7 rotates around the first connection, so that the seed spacing can be accurately controlled by adjusting the angle between the seed delivery tail pipe and the ground plane; the seed spacing is increased by adjusting and increasing the angle between the outlet of the seed delivery tail pipe and the ground plane.

[0036] In this embodiment, a plurality of seed delivery branch pipes 6 are provided; a plurality of seed distributor outlets are provided; and the inlets of the plurality of delivery branch pipes are connected to the outlets of the plurality of seed distributors 5 in a one-to-one correspondence.

[0037] In this embodiment, a plurality of seed delivery tail pipes 7 are provided; the inlets of the plurality of seed delivery tail pipes 7 are connected to the outlets of the plurality of seed delivery branch pipes 6 in a one-to-one correspondence.

[0038] In this embodiment, the plurality of seed delivery tail pipes 7 are arranged linearly.

[0039] Through the above technical solution, several seed delivery tail tubes are provided according to the sowing width and are arranged linearly. Preferably, there is no spacing between the outlet ends of the seed delivery tail tubes, and ridgeless sowing is achieved between the outlet ends of two adjacent seed delivery tail tubes.

[0040] Among them, preferably, there is no spacing between the outlet ends of the seed delivery tail tubes to achieve more precise control of the grain spacing; multiple seed delivery tail tubes are arranged linearly, so that the outlet ends of multiple seed delivery tail tubes are located on the same horizontal line, and there is no spacing between the outlet ends of two adjacent seed delivery tail tubes, and they are fitted together, so that the seed flow flows out evenly from the outlet ends of the seed delivery tail tubes, realizing ridgeless sowing.

[0041] In this embodiment, the outlet end of the seed delivery tail pipe 7 is in a flat bell-mouth shape.

[0045] The seeds in the seed box 1 are discharged from the seed metering device 3 at the outlet of the seed box 1. The seed metering device 3 discharges the seeds in the seed box 1 in a quantitative manner. While discharging the seeds, they are transported to the seed distributor 5 connected to the outlet of the seed conveying main pipe 4 under the action of the airflow blown by the fan 2. After being distributed by the seed distributor 5, the seeds enter each seed distribution branch pipe, and finally flow out from the seed conveying tail pipe 7 and are evenly sown on the seed bed.

[0046] The utility model provides an air-conveyed wheat ridgeless uniform seeder. The fan rotates to generate airflow, which is blown into the seed conveying main pipe. The seeds discharged by the seed meter are mixed with the pressurized gas in the seed conveying main pipe and are conveyed to the seed distributor under the action of the airflow. The seed distributor can evenly distribute the seeds wrapped in the airflow to each seed conveying branch pipe. When the seeds reach the end of the seed conveying tail pipe, they fill the flat outlet at the end of the seed conveying tail pipe under the action of the airflow, are further dispersed, and are evenly scattered on the seed bed. Since the seeds are conveyed with the escort of the pressurized airflow throughout the whole process and are evenly distributed by the seed distributor, more even sowing can be achieved. A number of seed conveying tail pipes are provided according to the sowing width and are linearly distributed. There is no interval between the seed conveying tail pipes, so as to achieve ridgeless sowing.
