Description

A kind of corn cob stem and harvesting table of corn cob stem and harvesting platform with helper roller type

technical field

The utility model relates to a stand suitable for being installed on a corn harvester, in particular to a corn ear stalk and harvesting platform of a corn ear stalk and harvesting platform with a roller-supporting type for breaking ears, collecting stalks, cutting stubble and returning to the field, belonging to the technical field of corn harvesting machines.

Background technique

The corn harvesting header is the most important working part of the corn harvester. At present, according to the working method, it is mainly divided into a roller-type ear-picking harvesting header and a plate-type ear-picking harvesting header. However, the traditional corn harvester header mainly has the following problems: the problem of misaligned harvesting, the existing corn harvester cannot be matched with agronomy, cannot adapt to different corn planting specifications, and cannot perform cross-regional operations; The platform relies on the stretching and squeezing action of the conveying roller on the corn stalk and ear to complete the ear picking, which produces a squeezing and rubbing force on the root of the ear, which can easily damage the corn ear and cause serious damage to the grain; plate-type ear picking is harvested The platform uses the ear baffle to clamp the root of the corn ear, and the corn stalk is forcibly broken by the stalk roller to achieve ear picking, which is likely to cause problems such as broken stem, blockage, and high power consumption; after picking the ear, the traditional corn harvester will The corn stalks are overwhelmed and difficult to return to the field and smashed. The straw returning machine will be used later, which increases the operating cost. Therefore, in order to solve the above problems, it is urgent to explore new principles and design new devices.

According to the research, the bending and breaking method of artificially breaking the ears will not cause damage to the corn, and the power consumption is small, which has become the basis for the study of new methods for harvesting and picking ears of corn.

Contents of the invention

The purpose of this utility model is to provide a kind of corn cob harvester and harvesting platform of corn cob and stalk harvesting type, which can solve the technical problems existing in the existing corn harvester, avoid the loss of corn kernels, and reduce the corn grain loss. It reduces power consumption, improves row spacing adaptability, and realizes both ears and stems.

The technical solution adopted by the utility model to solve the technical problem is: a corn cob stem and harvesting platform of the corn cob harvesting platform of the corn cob harvesting platform of the corn cob harvesting platform, including the cob cob and cob harvesting device, the cob collection device, Stalk collection device, stubble cutting and returning device, frame, the header adopts a modular design, each group is a single unit, connected with a tractor or a self-propelled harvesting host through the frame, and can be used for 1 to 50 rows of different corn Harvester series. The integrated device for pulling stems and breaking ears consists of a grain divider, a helping roller, a gearbox, a reel, a cutter, a single bracket and a stem pulling and breaking roller, which is located at the front of the header; the stalk collecting device It includes the stalk pulling wheel and the stalk collecting auger, which are placed on the rear and upper part of the integrated device for pulling stems and breaking ears; the ear collecting device includes ear conveying augers, ear collecting buckets and ear conveyors, which are located at the top of the integrated device for pulling stems and breaking ears. Rear bottom: The stubble cutting and returning device is placed under the ear collection device, which is composed of a stubble cutting device and a chopping and returning device, which are used to chop corn stubble and lower stalks.

Further specifically explain the technical solution: the grain divider is connected with the grain-supporting roller and is located at the front of the header, which can pick up corn plants with serious lodging, and expands the adaptability of row spacing and the ability to support various corn plant states, especially for corn plants. Lodging the corn plants; the helping roller is connected with the stem pulling and ear breaking roller through the gearbox, and there is a reel above the helping roller, which is used to overcome the dead point of the connection and feed the corn plants; the cutter is placed It is directly below the entrance end of the stem pulling and ear breaking wheel; the ear collection bucket is behind and below the stem pulling and ear breaking roller, inclined downward, and connected with the ear collecting auger, and the ear collecting auger transports the corn ears to the corn ear through the ear conveyor. The grain collection box at the back of the corn harvester; the stalk pulling wheel is installed above the rear and upper part of the stem pulling and ear breaking roller, and the extracted upper stalk is dialed into the stalk collecting auger; the stalk collecting auger is equipped with a chopping blade, While cutting the stalks, the corn stalks are further chopped; the stubble cutting and returning device is installed at the rear and lower part of the header, which is used for cutting stubble and crushing the lower stalks for returning to the field.

When working, the corn harvester transmits the power to the header through the traditional system, and each part of the header starts to run. The corn plants are picked up and supported by the grain divider and the auger, and are fed to the harvester under the cooperation of the reel. Stem pulling and ear breaking roller; while the corn plants are being fed, the cutter cuts the stalks from the lower part, and the corn plants with ears on the upper part are conveyed and pulled upwards and backwards under the clamping action of the stem pulling and ear breaking rollers moving in opposite directions. The ear of corn hits the stem pulling roller and receives the downward lateral force, the ear of corn is broken off, the ear of corn falls to the ear collection bucket, and slides down to the ear conveying auger, and the ear conveying auger collects in the middle or one side , transported to the grain collection box through the ear conveyor; the corn stalks on the upper part of the ear are pulled up by the stem breaking roller, and the rotating stalk wheel at the same time dials the straw into the stalk collection auger, and the stalk collection auger Equipped with a chopping knife, it can be chopped while being collected, and finally transported to the grass collection box; the corn stalks without ears in the lower part are dug and crushed and returned to the field under the action of the stubble cutting and returning device.

The beneficial effects of the utility model are: 1) the header is compact in structure, reliable in operation, stable in performance, and improves the harvesting efficiency of corn; It improves the ability to pick up and support different corn plant states, especially for corn plants in the lodging state, which is conducive to cross-area operations; Cutting the ear while breaking the ear solves the problem of ear damage; 4) The height of the cutting knife is adjustable and can be adjusted up and down according to requirements to realize the recovery of all corn stalks or partial recovery and partial return to the field; 5) The height of the header can be adjusted, which can Adapt to corn plants with different ear heights, and improve the adaptability to different corn varieties.
