Abstract

The present invention relates to two systems for driving cut material: a trailing system (B1) and a self-cleaning and suspended conveyor system (B2) applied on a cutting platform for grain harvesters, where the material cut by the cutting system is driven from the sides to the center of the platform (14) by element of two chain systems, wherein in the drag system (B1) multiple toes are mounted on a horizontal chain and in the self-cleaning and suspended conveyor system (B2) and multiple cast (perforated) cradles are mounted on the horizontal chain. In this way, both systems, drag and/or drop conveyors, shall be driven by hydraulic or electric motors or a mechanical system and a cutting platform can use one or the other conveyor systems, that is, the drag or suspended systems shall be used.

Description

[0016] In this case one has:

[0017] FIG. 1 shows the system top view proposed with all elements and [0018]

[0018] FIG. 2 shows two new concepts (arrangements) for transporting harvested material mounted on a chain in the horizontal direction, where the first arrangement (B1) refers to the multi-toed drag conveyor system mounted on a horizontal direction chain and base plates and fixed and movable protection. The second arrangement (B2) refers to the suspended and self-cleaning conveyor system with multiple cast (perforated) cradles and mounted on a chain in the horizontal direction of the harvested product.

[0019] FIG. 3 shows how the displacement is enabled (back-and-forth) of the drag conveyor system with back-and-forth chains and plates (PE-UHMW).

[0020] Some preferred form of construction of the proposed conveyor systems employs a cutting platform consisting of some main chassis (1) in which all the elements are connected, wherein said platform discloses the reciprocating cut-off system (2) which cuts the material to be harvested. With the aid of the reel (3) the material is driven through a rotational movement (4) in the direction indicated by the arrows (5).

[0021] In the first arrangement, which features a drag conveyor system, the flow (6) occurs from the side to the center through toe dragging (B1). This chain system can be driven by a hydraulic motor or an electric or mechanical system (7). The displacement velocity of the driven chain shall be variable due to the volume density of the product harvested, speed of the machine displacement and other factors such as straw moisture and crop variety. The entire toe system mentioned above and protected by polymeric material plates (PE-UHMW), which has some low coefficient of friction, allowing the sliding of the harvested material, facilitates the drag work done by the chain and toe system.

[0022] For better understanding, the description of the assembly of the PE-UHMW plates set and of the set of tensile chains shall be provided.

[0023] The plate system consists of three plates, each with their respective functions.

[0024] The base plate (8) forms the base on which the chain system (B1) is mounted and connects the cutting system and the chain system, allowing flexibility between the two.

[0025] The movable protection plate (9) is mounted on the chain system (B1) and has the function of isolating the harvested material so that its drag by the chain system toes is only in the direction of the end towards the center of the platform, avoiding the accumulation of material and maintaining a continuous flow of material to the central part of the platform.

[0026] The fixed protective plate (10) is mounted on the movable plate (9) and set on the platform chassis (1) and is intended to prevent the accumulation of material between the platform chassis (1) and the chain system (B1). It also allows the displacement of the chain system (B1) and the movable plate (9) back-and-forth through the linear actuators (11), producing the back-and-forth movement (12).

[0027] All material moving from the ends to the center through the chain and plate systems upon reaching the center of the platform is driven into the harvester through a conveyor (14) which is driven by a hydraulic motor, an electric or mechanical system with variable speed according to the volumetric density of the material to be harvested, speed of machine displacement and other factors such as straw moisture and crop variety. The belt (14) moves in the direction indicated (16) and the harvested material is moved (15) into the harvester.

[0028] The back-and-forth movement (12) of the movable plates and chain system is made by means of two linear actuators, one at each end (DETAIL C), wherein the linear actuator (11) moves by independently acting and withdrawing, producing the forward or backward (back-and-forth) displacement of the system, according to items 12 and 13. Such displacement shall depend on the volumetric density of the material to be harvested, the speed of the machine displacement and other factors such as straw moisture and crop variety.

[0029] The second arrangement describes a self-cleaning suspended conveyor system consisting of a chain in the horizontal direction and multiple elements folded with suitable degrees (B2), in which are assembled (18) and in which the harvested products shall be transported in a suspended manner, which shall contribute to maintaining the grain quality as there shall be no impact on it. These multiple elements shall be cast (perforated) to allow the soil collected along with the product harvested in the cutting process to be released to the soil before entering the harvester.

[0030] The product cut by the cutting system is driven with the help of the reel (3) to the cradle of the suspended conveyor system (B2). The system is driven with hydraulic, electric or mechanical motors according to (19), which shall move the chain of the suspended conveyor in the direction indicated (20), causing the displacement of the product harvested from the side to the center of the platform. Such displacement shall be variable. All products, when arriving in the center of the platform, shall be taken to the interior of the harvester with the aid of a conveyor belt. The belt displacement (14) follows the direction of the arrows (15) and the product enters the harvester according to the arrows (16).
