Description

A subsoiling rotary tillage seeding unit

technical field

The utility model relates to a subsoiling rotary tillage seeding unit, which belongs to the technical field of agricultural seeding machinery.

Background technique

Wheat and corn are the main crops in northern my country. The traditional farming system is to sow wheat after returning corn stalks to the field for plowing in autumn. With the increasing shortage of water resources and the development of water-saving agricultural technology, the emerging conservation tillage in recent years is an advanced agricultural farming technology that integrates environmental protection, conservation and efficiency. Plowing and sowing are the main content. On the one hand, it avoids the excessive evaporation of soil water caused by bare soil and over-plowing; , At the same time, due to the annual straw returning to the field and stubble rot, the organic matter content of the soil is effectively increased, and the soil fertility is enhanced, thus playing the role of water conservation, soil conservation, fertilizer conservation, and increase in production and income. Conservation tillage mainly includes four aspects, no (less) tillage technology, straw mulching technology, subsoiling technology and chemical weeding. In production practice, because this type of seeder adopts ditches to sow wheat, although various improved sowing ditchers are disclosed on the market, field stalks still often affect the passing rate of the sower.

Contents of the invention

The purpose of the utility model is to provide a protective tillage planting unit which integrates various technologies and completes combined operations such as field corn stalk mulching, strip-shaped less tillage, subsoiling, and deep application of chemical fertilizers at one time.

The technical scheme of the utility model is realized in the following way: the basic structure of this subsoiling rotary tillage seeding unit includes a tractor, a frame connected to the tractor, a seed box and a fertilizer box arranged on the frame, and a row of rowers arranged at the bottom of the frame. The seed pipe, the fertilization pipe, and the cover wheel and the pressure roller are mounted on the back of the frame. It is characterized in that a rotary tiller and a subsoiler are arranged in front of the seeding pipe of the seeder, and the subsoiler is located between two sets of rotary knives and two rows of wheat In the middle of the seed tube.

For the subsoiling rotary tillage and seeding unit, a water storage tank and a water distribution tank are arranged on the frame, and a watering pipe is arranged behind the seeding pipe.

In the rotary tillage ditch fertilization watering and seeding machine, a corn stalk combing machine and a crop divider are arranged in front of the tractor.

In the subsoiling rotary tillage planting unit, the pressing roller is provided with a cantilever that is hinged to the frame, a fixed rod is provided between the frame and the cantilever, and a suspension arm is also provided on the cantilever.

For the subsoiling rotary tillage seeding unit, a fertilization pipe is arranged in front of the seeding pipe of the seeder.

The utility model uses a rotary tiller to carry out belt-shaped rotary tillage and ditching on the sowing belt, which can effectively ensure the coverage rate of the seeds and the passing rate of the seeder, and effectively solve the problem of blockage of the machine tool. At the same time, the power of the tractor is saved, and the integrated operation of subsoiling and less tillage can be realized. Effectively reduce the number of machine operations into the ground. The utility model is also equipped with a water storage tank and a water distribution tank. The water storage tank can carry 1.5 tons of water each time. When the soil moisture is insufficient, it can realize watering and sowing; the water distribution tank is equipped with a water divider to make the amount of water applied in each row as uniform as possible. . The pressing roller of the utility model can be folded upwards, so that the center of gravity of the implement can be moved forward, which is convenient for transportation.

Detailed ways

Fig. 1 is a schematic diagram of the structure of the utility model and the supporting operation of the tractor. Its basic configuration includes: a corn stalk combing machine, a tractor, and a planting unit, which are suitable for sowing 4 rows of wheat with a row spacing of about 700mm in corn, and strip-shaped rotary tillage between rows. 60-65 high-horsepower tractor supporting.

The operation process of rotary tillage and sowing is shown in Figures 1, 2 and 3: a corn divider 1 and a straw comb press 15 are installed in front of the tractor 2 to overwhelm the straw; 12. The seed box 16, the fertilizer box 5, and the water distribution tank 4 are set on the frame, and the rotary tiller blade 6, the subsoiling shovel 19, the fertilization pipe 7, the seeding pipe 8, and the watering pipe 9 are installed on the lower part of the frame. Connected earth covering wheel 10 and pressing roller 14 are made up.

The seeder of the utility model shares the suspension device of the tractor, and the corn stalk combing machine, the water storage tank 3 and the wheat subsoiling rotary tillage planting unit are all mounted on the tractor, which can complete the field corn straw covering, ditching, Fertilization, seeding, watering, soil covering, suppression and many other operations. The utility model uses the rotary tiller 5 to carry out strip-shaped rotary tillage ditching for the sowing belt, and uses the subsoiler shovel 17 to carry out subsoiling of the soil. After the subsoiler shovel, a fertilization pipe 7, a seeding pipe 8, and a watering pipe 9 are arranged to realize Fertilizers are applied deeply, the depth of subsoiling and the distance between fertilization and seeding are adjustable, and the subsoiling shovel is located in the middle of the two rows of seeding tubes. As shown in Figure 5, the depth of subsoiling and fertilization is different from that of the rotary tiller. The depth of subsoiling is about 15cm, and the depth of fertilization is about 8-10cm. The fertilization position is located at the side of the sowing ditch 5cm below the seed and 50mm. In the middle of the rotary tiller, the passability of the machine is good, which effectively solves the problem of machine blockage.

The extended technical solution of the utility model is that the tractor is equipped with a water storage tank 3 and a water distribution tank 4. The water storage tank can carry 1.5 tons of water each time. 18. Make the amount of water applied in each row as uniform as possible.

In order to facilitate the transportation and walking of the planting unit, the technical solution provided by the utility model is to set the cantilever 13 and the suspension arm 1 hinged with the frame on the pressing roller 14, which can be folded up during transportation, so that the center of gravity of the equipment can be moved forward, which is convenient Transport, as shown in Figure 4.
