Abstract

The utility model relates to a header frame for a harvester, comprising a left side plate, a right side plate, a front header beam, a rear header plate, an upper beam, a hanging pipe and a header outlet. In the header frame for a harvester, reinforcing ribs are arranged between the front header beam and the rear header plate; the left side plate and the right side plate are of a whole plate structure on which a mounting hole and an installing gap are arranged, and the upper edges of the right and the left side plates are bent and folded outwards by steel plates to form upper folded edges; the upper beam is a trough girder with a downward opening, and the hanging pipe is connected to the rear header plate and the upper beam by a triangular supporting frame. The header frame for a harvester has the advantages of simple process and manufacture, high strength, less material consumption, low cost, etc. The utility model can universally replace the existing header frame for a harvester.

Description

The harvester header frame

The utility model relates to the harvester header technology, is a kind of harvester header frame.

Existing harvester header frame mainly include the left side plate 1 formed by several different components ', ceding of Taiwan front-axle beam 2 ', plate 3 after the ceding of Taiwan ', the upper beam 4 of truss structure ', by angle steel up and down be fixed on the plate and suspended tubes 5 that be used to hang header after the ceding of Taiwan ' and the ceding of Taiwan export 6 ', ceding of Taiwan front-axle beam and back have between the plate reinforcement 7 ' on, about structure sees also Fig. 1 and Fig. 2; In use, since its auger conveyor by bearing etc. be installed in front-axle beam 1 ' with back plate 3 ' between left and right sides plate 1 ' on, power is via the suspended tubes right side and by power-actuated belt pulley, be assemblied in the power transmission shaft in the suspended tubes, suspended tubes left side and the belt pulley that links to each other with power transmission shaft, the belt pulley that is enclosed within belt on the belt pulley and auger conveyor end is passed to auger conveyor and is carried out work, while power is passed to the anterior cutter transmission mechanism of installing of the ceding of Taiwan by relevant connecting gear and is gathered in, the crop that cuts off is delivered to ceding of Taiwan outlet by auger conveyor, export the conveyor of harvester that is delivered to ceding of Taiwan exit by the ceding of Taiwan, finish the harvesting work of the whole ceding of Taiwan, relevant this part technology is the course of work of existing harvester header, and from figure, can imagine yet and draw, thereby do not draw in detail in the drawings; Member is more in the header frame of this structure, as the upper beam of left side plate among the figure and truss structure by several members by the connection of frame modes such as welding, its stiffness effect is bigger, intensity is relatively poor, the processing technology complexity, more its cost of consumptive material is higher.

The purpose of this utility model is to provide the novel harvester header frame that a kind of structural elements is less, mounting structure is simple, intensity is high, consumptive material is few and cost is low according to above-mentioned situation.

Harvester header frame of the present utility model mainly is the improvement to existing harvester header rack construction, it comprises plate after left side plate, ceding of Taiwan front-axle beam, the ceding of Taiwan, puts the beams in place, is used to hang the suspended tubes and the ceding of Taiwan outlet of the ceding of Taiwan, ceding of Taiwan front-axle beam with afterwards have on the reinforcement between the plate; Left side plate wherein is whole plate structure, has the bearing mounting hole and the cutter transmission mechanism assembling breach of auger conveyor thereon, and the top edge of left side plate outwards has been bent into the last bending edge of booster action by steel plate; It is put the beams in place and is the trough girder that Open Side Down; On its suspended tubes connects after the ceding of Taiwan plate by the triangle integral support and puts the beams in place.

That harvester header frame of the present utility model has is simple and reasonable, processing and fabricating is simple, intensity is high, consumptive material reaches characteristics such as cost is low less, can generally replace existing harvester header frame.

Below in conjunction with accompanying drawing technology contents of the present utility model and design feature thereof are further described:

Fig. 1 is the schematic top view (relevant auger conveyor etc. is not drawn) of existing harvester header frame;

Fig. 2 is the schematic side view of Fig. 1;

Fig. 3 is top view structural representation of the present utility model (structure such as auger conveyor is not drawn);

Fig. 4 is the side-looking structural representation sketch of Fig. 3.

Referring to Fig. 3 and Fig. 4, header frame of the present utility model mainly is the improvement to existing harvester header rack construction, suspended tubes 5 and ceding of Taiwan outlet 6 that it comprises plate 3 after left side plate 1, ceding of Taiwan front-axle beam 2, the ceding of Taiwan, put the beams in place 4, be used to hang header, have on the reinforcement 7 between ceding of Taiwan front-axle beam and the back plate, the clear shape of the connection of these members is consistent with existing harvester header frame, and the syndeton between the member mostly adopts Type of Welding to connect; Left side plate 1 wherein is whole plate structure, has the bearing mounting hole 11 and the cutter transmission mechanism assembling breach 12 of auger conveyor thereon, and the top edge of left side plate 1 outwards has been bent into the last bending edge 13 of booster action by steel plate; Its upper beam 4 is the trough girder that Open Side Down; Its suspended tubes 5 is connected after the ceding of Taiwan plate 3 by triangle integral support 8 and puts the beams in place on 4.

According to the shape need of side plate, simple in order to guarantee processing and fabricating, above-mentioned left side plate also can adopt two block plates to connect into whole plate structure (as shown in Figure 4) by weldering.

Above-mentioned reinforcement 7 preferably adopts angle steel, can satisfy its requirement of strength (as shown in Figure 3) when saving material again to reach.

Consistent described in the installation of harvester header frame of the present utility model and auger conveyor and power transport process and the background technology; Assembling as for the cutter transmission mechanism please refer to existing harvester header technology, no longer describes in detail at this.Have simple and reasonable, processing and fabricating is simple, intensity is high, consumption is luxurious reaches characteristics such as cost is low less, can generally replace existing harvester header frame.
