Description

Backpack Three Ridge Corn Combine Harvester

technical field

The utility model belongs to agricultural machinery, and mainly relates to a corn harvesting machine tool.

Background technique

At present, the corn harvesting equipment used in my country's agricultural production for 18-28 horsepower small-horsepower four-wheel tractors mostly adopts traditional structures such as horizontally configured equal-diameter ear-picking rollers and single-side reeling of a single reel. Corn harvesting needs to be equipped with a pair of horizontal equal-diameter ear picking rollers on the machine tool, which not only complicates the structure of the machine tool, increases the manufacturing cost, but also increases the power consumption of the operation, so that the small horsepower tractor with 18-28 horsepower can only be equipped with 1- 2 Ridge corn harvesting equipment is used, but the peeling operation of corn ears cannot be completed, the operation function is not complete, the operation efficiency is reduced, and the operation cost is increased. In addition, after the ear is picked by the horizontal equal-diameter ear picking roller, the falling direction of the corn ear is uncertain, and it is not easy to fall into the elevator, which affects the recovery rate of the corn ear and increases the amount of manual auxiliary labor; More, it also affects the operation effect of the machine tool.

Contents of the invention

The purpose of this utility model is to aim at the problems existing in the above-mentioned prior art, and to design and provide a new structure of a piggyback three-ridge corn combine harvester, so as to simplify the ear picking structure of the equipment, reduce the power consumption of the ear picking operation, improve the operating efficiency, increase the Operation items and the purpose of ensuring the quality of the operation.

The basic design of the utility model is that the three-row harvesting head assembly is suspended on the front end of the small-horsepower four-wheel tractor, and an unequal-diameter ear-picking roller assembly is vertically configured and installed on the stem of the three-ridge harvesting head assembly. On the outside of the output end, the ear peeling device and the secondary elevator are integrally installed on the rear side of the small-horsepower four-wheel tractor, and the primary elevator is equipped on the side of the small-horsepower four-wheel tractor. The parts are respectively communicated and cooperated with the unequal-diameter ear-picking roller assembly and the ear peeling device, so far to form a backpack-type three-ridge corn combine harvester.

The utility model adopts the three-ridge harvesting table assembly which is suspended on the front end of the small-horsepower four-wheel tractor and connected to the double-sided reel, and a vertically arranged unequal-diameter fringe-picking roller assembly and a back mounted on the small-horsepower tractor. The overall structure of the ear peeling device and the secondary elevator on the rear side of the wheel tractor can complete the ear picking, peeling, lifting and loading operations of three ridge corn ears in one operation, and keep the corn stalks intact. It has the characteristics of low power consumption, good operation quality, high efficiency, complete functions and low cost.

Detailed ways

The best implementation of the utility model will be described in detail below in conjunction with the accompanying drawings. A backpack-type three-row corn combine harvester, which is mounted on the front end of a small-horsepower four-wheel tractor 1 and equipped with a three-row header assembly 2, and a unequal-diameter ear-picking roller assembly 3 is vertically configured and installed on the three-row The outer side of the stem output end of the harvesting head assembly 2, the ear peeling device 5 and the secondary elevator 6 are integrally mounted on the rear side of the small-horsepower four-wheel tractor 1, and the primary elevator 4 is assembled on the small-horsepower four-wheel tractor 1. On the wheel tractor 1 side, its front end and rear side are respectively communicated with unequal diameter picking roller assembly 3 and fruit ear peeling device 5 and cooperate. The unequal diameter ear picking roller assembly 3 is composed of a front spiral ear picking roller 8 and a rear side spiral ear picking roller 7 vertically and parallel to each other, and the outer diameter of the front side spiral ear picking roller 8 is larger than that of the rear side Spiral plucking ear roller 7 outer diameter dimensions, the helical direction of front and back side spiral plucking ear roller 8,7 is left-handed and right-handed respectively. The three-ridge harvesting head assembly 2 includes a header conveyor belt 12, two central grain divider assemblies 13, a beginning end grain divider assembly 9, an end grain divider assembly 10 and the main reel 14. The auxiliary grain reel 11 of elastic structure is respectively equipped on the starting end grain divider assembly 9 and the central grain divider assembly 13 of the three-ridge harvesting header assembly 2, and the auxiliary grain reel of the central grain divider assembly 13 11 and the main reel 14 are equipped with driven gear or driven sprocket 16 and driving gear or driving sprocket 15 respectively, and communicate with each other, auxiliary reel 11 is opposite to main reel 14 directions of rotation; driving gear 17 and The driven gear 18 is respectively installed on the main reel 14 and the auxiliary reel 11 of the grain divider assembly 9 at the starting end, and directly meshes.

During operation, the small-horsepower four-wheel tractor 1 drives the machine forward, and drives the three-ridge harvesting header assembly 2, the unequal-diameter ear picking roller assembly 3, the primary elevator 4, the ear peeling device 5 and the secondary The elevator 6 rotates, and the corn stalks with corn ears enter the three-ridge harvesting head assembly 2 under the guidance of each grain divider assembly 9, 13, 10, and the main and auxiliary reels 14, 11 cooperate with each other The corn stalks are dialed in so that the corn stalks are in contact with the header conveyor belt 12, and are sent horizontally to the vertically configured unequal-diameter ear-picking roller assembly 3 to complete corn ear picking. Carrier 4 enters in ear peeling device 5 and carries out peeling operation, and the ear of corn without skin is sent in the accompanying trailer bucket through secondary elevator 6.
