Description

A self-propelled corn combine harvester with straw pre-cut, laying and returning to the field

technical field

The utility model relates to an agricultural machine.

Background technique

Corn is one of the main crops in my country. The summer sown corn in my country is mainly concentrated in the Huanghuaihai region, which is the most concentrated corn production area in my country. The sown area is about 130 million mu, accounting for more than 40% of the total corn area in the country. This area is generally a two-crop planting mode a year, and most of them are in a state of large-scale contiguous planting, which is relatively easy to realize mechanized combined harvesting operations. However, due to the different planting patterns and harvesting requirements in various places, a variety of corn combine harvesters have been formed on the market. Moreover, corn stalks are an important biological resource with a huge amount of resources. Most regions and users require corn stalks to be chopped and returned to the field as organic fertilizers. It is precisely because of the large area of corn planting in the Huanghuaihai region of our country and the requirement that the straw be chopped and returned to the field as an organic fertilizer, which requires a new type of corn combine harvester to adapt to the planting mode and harvesting requirements of the Huanghuaihai region.

The main technical problems currently existing in my country's corn combine harvester are:

(1) Most of the existing corn combine harvesters in the Chinese market are equipped with a straw chopping and returning device at the rear or middle of the machine. The effect of crushing and returning to the field is poor.

(2) The existing corn combine harvester in the front of the straw chopping and returning device in the Chinese market makes the front part of the machine heavier and the mass distribution is uneven, which affects the flexibility and stability of the machine.

(3) The existing corn harvester does not pre-cut the stalks after ear picking, the power consumption of the stalk cutting and returning device is large, and the returning effect is poor.

Utility model content

The ear collecting device is located on the frame and is used to collect the ears after picking on the ear harvesting platform. Under the table, the straw after ear picking is cut by the straw pre-cutting hob, then discharged by the straw laying auger, and laid on the ground between the two tires, and the straw laid on the ground is then chopped by the straw in the middle of the machine The field returning device returns to the field, which can avoid the phenomenon that the tires are crushed by the straw, the chopping effect is good, and the power consumption of the field returning machine is low.

As a further improvement of the utility model, the straw chopping hob includes a blade and a hob shaft tube, and the straw laying auger includes a left-handed blade, a dial, a right-handed blade and an auger frame, and the left-handed blade, dial , The right-handed blade is fixed on the auger frame, the dial is located between the left-handed blade and the right-handed blade, the auger frame is installed on the ear picking harvesting platform, the straw chopping hob is installed on the auger frame, After the straw is cut by the straw pre-cutting hob, the left-handed and right-handed blades on the straw laying auger are concentrated in the middle, and the paddle in the middle is discharged outwards, and laid on the ground between the two tires. The straw on the ground is returned to the field by the straw chopping and returning device in the middle of the machine, which can avoid the phenomenon that the tires crush the straw, the effect of chopping and returning to the field is good, and the power consumption of the returning machine is low.

The ear harvesting table, the straw pre-cutting hob and the straw laying auger can be lifted together, and the ear picking harvesting table can also be lifted separately through the oil cylinder.

Further, the ear collection device includes a first-level elevator, an ear peeling device, a second-level elevator, and an ear collection box connected in sequence; the ears after picking by the ear harvesting platform enter the ear peeling through the first-level elevator. The device performs peeling, and then enters the ear collection box through the secondary elevator.

The self-propelled corn combine harvester of the straw pre-cut, laying and returning type also includes an engine, and the engine may be located above the rear frame of the ear peeling device.

The ear peeling device is located above the frame at the rear of the cab, and the ear collection box is located above the frame at the rear of the ear peeling device.

The beneficial effect of the utility model is that the adaptability of the corn combine harvester to the needs of users in the Huanghuaihai region is improved, the quality of straw returning to the field is improved, and the power consumption of the straw chopping and returning device is reduced. Large-scale operations provide basic conditions.
