Description

A seed and fertilizer spreading device based on double disc covering soil

technical field

The invention relates to a tillage machine, in particular to a seed and fertilizer spreading device based on double-disc soil covering, and belongs to the field of agricultural machinery.

Background technique

Seeding and fertilization are essential operations in agricultural production. In order to reduce the operating procedures and improve the utilization efficiency of chemical fertilizers, most of the existing planters use seed fertilizer distributing devices to complete the sowing and fertilization operations at one time. Most of the existing sowing and fertilizing machines rely on natural return to the soil to realize the separation of seed and fertilizer. However, the natural return method is easily affected by the soil moisture content, the degree of looseness of the soil block, and the operating speed of the machine. It is prone to insufficient return soil, resulting in mixed application of seed and fertilizer, and then burning seedlings. In order to solve this problem, the patent document with the invention patent No. 201710290628.3 discloses a sowing and fertilizing device for actively covering soil, which is characterized in that it includes a fertilization shovel, a shovel handle, a fertilizer feeding pipe, a fertilizer discharge pipe, a seed meter, and a seed pipe , fertilization plate, soil retaining plate, soil pressure plate, fixed plate, wherein, the fertilization shovel is located at the front and lower part of the shovel handle, the fertilizer feeding pipe is located at the front and upper part of the shovel handle, the fixed plate is located at the rear of the shovel handle, and the fixed plate is provided with a soil entry The soil retaining plate passes through the soil inlet, the fertilizer pressure plate is welded behind the shovel handle, the soil pressure plate is installed between the two fixed plates, the seed meter is located above the fixed plate, and the fertilizer discharge pipe and the seed discharge pipe are in the same ditch Fertilization and seeding are applied successively in the trough, and soil pressing boards, soil retaining boards, and fertilizer pressing boards are used to actively cover the soil to realize the separation of seeds and fertilizers and complete high-quality sowing and fertilization work. Although the invention can realize the separation of seed and manure by actively covering the soil with the soil retaining plate, when working under the condition of no-tillage or poor soil moisture, there will be a phenomenon of blockage of the soil inlet, resulting in the mixed application of fertilizer and seeds, which not only reduces the yield of seeds. Survival rate, but also reduce the utilization rate of fertilizer. Therefore, by designing a seed fertilizer spreading device based on double disk covering soil, it can effectively prevent clogging, increase the amount of soil returned, ensure sufficient soil covering between seed fertilizers, and meet the agronomic requirements of crop growth for seed fertilizer spacing.

Contents of the invention

In order to solve the above-mentioned technical problems, the present invention provides a seed and fertilizer spreading device based on double-disc soil covering.

The technical solution adopted in the present invention is: a kind of fertilizer spreading device based on double-disc covering soil, comprising four parts: a fertilization ditch opener, a fixed plate, a double-disc soil-covering device and a sowing ditch opener; The furrow device is composed of a fertilizing shovel and a shovel handle, wherein the fertilizing shovel is located at the front and lower part of the shovel handle, the fixed plate is located at the rear of the shovel handle, and the fixed plate is opened with a chute, and the double-disc soil covering device is located at the bottom of the fertilization ditch opener. It is installed on the two fixed plates through bolts. The double-disc soil-covering device is composed of a soil-covering disc, a connecting bracket, a soil-covering disc shaft and a set screw. The sowing opener is located on the side of the double-disc soil-covering device. At the rear, it is installed between two fixed plates through bolts. The sowing opener is composed of a sowing shovel, a seed pipe, and a connecting plate. The soil-covering disc is used to actively cover the soil to ensure sufficient soil coverage between the seed and fertilizer, and realize the separation of the seed and fertilizer. , and then create conditions for sowing operations.

The double-disc soil covering device is located between the fertilizing ditch opener and the sowing ditch opener, and is installed on two fixed plates. During the rotation of the soil covering disc, the soil on both sides of the fertilizing ditch opener is covered back after the ditching operation. In the shallow fertilizer ditch, it can meet the requirements of the amount of covering soil between the seed and fertilizer. By adjusting the opening angle and installation height of the covering disc, the amount of covering soil between the seed and the fertilizer can be changed to meet the agronomic requirements of different crops for the distance between the seed and fertilizer. The direction of the opening angle of the disc is the same as the forward direction of the implement.

The beneficial effect of the present invention is that: by adjusting the opening angle and installation height of the soil-covering disk, the amount of returned soil can be changed to ensure a sufficient amount of soil-covered space between seed fertilizers and meet the agronomic requirements of different crops for the space between seed fertilizers.
