Description

Row and Seed Drills Matched with Tractors

technical field

The utility model relates to the technical field of agricultural machinery, in particular to the mechanical device technology of straw crushing and returning to the field and row tillage and sowing.

Background technique

In the existing agricultural production, walking tractors and medium-sized tractors are still used to carry out farmland operations. In most areas, straws are burned, and farms with conditions can crush straws. Field and strip plowing and drill sowing are combined operations at the same time, so the labor intensity of farmers is still high, the energy consumption of farming is high, and the cost of planting is high.

Ubiquitous present is: people cultivate first, and farmland is plowed in strips, and the hardened land is loosened, and after a period of maintenance, sowing is carried out. This farming method is both a waste of labor and a waste of time.

Utility model content

The purpose of the utility model is to provide a labor-saving and cost-saving row tillage drill matched with a tractor.

The utility model comprises a frame connected to the suspension frame of the tractor, a tiller shaft is arranged below the frame, a tiller is connected outside the shaft, a seed box is fixed on the upper part of the frame, and the seed box is connected to the seed box through the seed delivery pipe. The sowing head arranged at the lower part of the frame is connected, and the sowing head is arranged behind the strip cultivator.

The utility model uses the strip plow to till the soil in strips, and applies the fertilizer deep into the soil by the fertilizing head to realize one operation of strip tillage and drill sowing. The utility model can complete the two operation procedures at one time, which not only saves labor, but also saves cost. The utility model has a reasonable, simple and compact structure, has little damage to the surface soil, is beneficial to avoiding water and soil loss and sandstorms, greatly saves farming energy consumption, and reduces planting costs. The harvested stalks do not need to be cleaned, and are directly left in the field, and then directly cultivated by the utility model, which can also achieve the purpose of returning all the stalks to the field.

The utility model also arranges the grass cutting knife and the grass-piercing fence below the frame, and the grass-cutting knife and the grass-piercing fence are placed in the place ahead of the plowing knife shaft. With the help of the grass fence, the grass cutter cuts the straw placed in the field before row plowing and row sowing. In this way, three different operations can be completed at one time on one device, which saves manpower and material resources.

The utility model can also be provided with a fertilizer box on the frame, and the fertilizer box is connected with the fertilizing head arranged at the bottom of the frame through the fertilizer delivery pipe, and the fertilizing head is arranged at the rear of the blade. Sowing and fertilization can be completed at one time.

In addition, a pressing wheel can also be arranged under the frame, and the pressing wheel is arranged behind the fertilizing head and the sowing head. The land is flattened by the pressing wheel, and the fertilizer and seeds are covered in the ground.

At least two sets of tiller discs are evenly distributed in the axial direction on the bar tiller shaft, and at least one blade is connected in the circumferential direction of each group of bar tiller discs; The distance ratio between the two strip cultivating cutter discs is 1/2 to 1/10.

At least two groups of blade holders are evenly distributed in the axial direction on the blade shaft, and at least one blade is arranged circumferentially on each group of blade holders; The distance ratio between the two blade holders is 1/2 to 1/10.

The above are the two fixing methods of the blades. The ratio of the distance between the nearest blade distance and the distance between two adjacent strip tillage discs or strip tillage seats is 1/2 to 1/10, which can form strip tillage operations with large spacing. .
