RU213830U1 - Active field divider combine harvester - Google Patents

Abstract

The utility model relates to agricultural engineering and can be used in combine headers for harvesting lodged and tangled grain.

An active field divider of a combine header, containing a disk cutter with a hydraulic motor and an anti-cutting plate, while the disk cutter is mounted on the sidewall of the header in a vertical plane on the shaft of the hydraulic motor fixed to a bracket welded to the sidewall of the header, and the anti-cutting plate is fixed to the inclined surface of the sidewall of the header with the possibility regulation of the gap between the cutting edges of the teeth of the disk cutter and the counter-cutting plate.

Description

Known active divider, consisting of a passive housing, in the front hinge bearing which is fixed to the rod. The rod is connected to a rotary motion drive, which allows the divider to penetrate into the lower layer of lodged stems and lift them (AS USSR No. 665848 class A. 01D 63/00).

The disadvantage of this active divider is the lack of further movement of the stem mass on the passive surface of the body, which does not allow efficient separation. In addition, a loose and rotted mass, weed stalks are strung on a rotating rod, which worsens the process of separation of the stems located in front.

Active type field dividers are known for harvesting agricultural machines for separating cut stems from those remaining on the field, in particular active field dividers with a segmented cutting device, including movable and fixed knives (AS USSR No. 197334 class A. 01D 63/00, A.S. USSR No. 354803 class A. 01D 63/00).

The disadvantages of these field dividers are the complexity of manufacturing and increased losses as a result of the continuous impact of the knives on the stems.

The closest in technical essence (prototype) is the field divider of the header (AS USSR No. 1007596 class A. 01D 63/02), mounted on the sidewall of the harvester and made in the form of an endless flexible element with grippers for stems, mounted on two pulleys , one of which is driven, and the pulley front in the direction of movement of the header is located below the rear one. In the process of operation of the specified field divider, significant damage to the stems takes place, in addition, the required quality of separating the cut stems from the total mass and supplying them to the cutting device is not ensured.

The claimed utility model is aimed at eliminating these shortcomings and the following technical result is obtained from its implementation: the proposed design of the active field divider makes it possible to improve the quality of separating cut stems from the total mass and reduce losses when harvesting lodged and tangled stems. The technical result is achieved due to the fact that an active field divider is installed on the sidewall of the combine harvester, made in the form of a disk cutter, installed in a vertical plane on the hydraulic motor shaft, and an anti-cutting plate, while the hydraulic motor is fixed to a bracket welded to the sidewall of the combine harvester, and the anti-cutting the plate is fixed to the inclined surface of the sidewall of the combine harvester with the possibility of adjusting the gap between the cutting edges of the teeth of the disk cutter and the counter-cutting plate.

Fig. 1. Scheme of the active field divider of the combine harvester.

An active field divider of a combine harvester containing a disk cutter 1 with a hydraulic motor 2 and an anti-cutting plate 3, while the disk cutter 1 is installed on the sidewall 4 of the harvester in a vertical plane on the shaft of the hydraulic motor 2, fixed to the bracket 5, welded to the sidewall 4 of the header, and the anti-cutting plate 3 fixed to the inclined surface of the sidewall 4 of the harvester with the possibility of adjusting the gap between the cutting edges of the teeth of the disc cutter 1 and the counter-cutting plate 3.

Active field divider works as follows.

When the combine harvester moves, the sidewall 4 enters with its toe into the layer of the lodged tangled mass of stems and lifts it. As the stems rise, they partially unravel. The remaining tangled stems are cut off by a disk cutter 1 mounted on the shaft of the hydraulic motor 3 in a vertical plane.

Thus, the proposed technical solution makes it possible to improve the quality of the separation of cut stems from the total mass and to reduce grain losses when harvesting lodged tangled bread.

Claims (1)

Active field divider of a combine harvester, containing a disk cutter with a hydraulic motor and an anti-cutting plate, characterized in that the disk cutter is mounted on the sidewall of the header in a vertical plane on the shaft of the hydraulic motor, fixed to a bracket welded to the sidewall of the header, and the anti-cutting plate is fixed to the inclined surface of the sidewall of the header with the possibility of adjusting the gap between the cutting edges of the teeth of the disc cutter and the counter-cutting plate.
