Abstract
The utility model discloses a rack bar structure of a reel device for a combine harvester. The rack bar structure comprises a plurality of rack bars uniformly distributed in the circumferential direction of the reel device, the two ends of each rack bar are fixedly connected with an end surface plate of the reel device, and a plurality of spring teeth taking the shape of the letter M and perpendicular to the rack bars are arranged side by side on the rack bars. At least one powerful pick tooth is symmetrically arranged at the two ends of each rack bar, and one end of the powerful pick tooth is parallel to a spring tooth and is fixedly and vertically connected with the rack bar. The rack bar structure provided by the utility model has a simple structure, the two ends of the rack bar of the reel device are symmetrically provided with one or two powerful pick teeth with higher intensity, even grains at the two ends of a header are more than that in the middle of the header, when the reel device rotates, grains at the two ends of the header are easily poked into the header through the powerful pick teeth, grain accumulation at the two ends of the header is avoided, the operation of the header is smoother, and the working efficiency of the combine harvester is improved.
Description
Technical field
The utility model relates to a kind of combine straw shift wheel structure, and especially a kind of being convenient to belongs to agricultural machinery technological field with the drag on straw shift wheel ratch structure of the ceding of Taiwan of the inboard a large amount of bread crops piled up of nearside divider.
Background technology
Straw shift wheel is horizontal in the combine front portion, the one end divides the standing grain side for separating of harvesting cereal, other end driving side links to each other with driving mechanism, straw shift wheel is uniform several ratch circumferentially, be arranged side by side many elastic claws perpendicular to ratch on the ratch, by elastic claw in a row cereal harrowed the into ceding of Taiwan during straw shift wheel rotation.During combine harvesting operation, a large amount of cereal have been piled up in the nearside divider inboard at ceding of Taiwan two ends, its weight has surpassed the middle cereal weight of the ceding of Taiwan, existing elastic claw diameter in a row is less, intensity is lower, moulding distortion easily takes place and damages in the elastic claw at ratch two ends when the cereal that pile up at rake ceding of Taiwan two ends, ceding of Taiwan both sides cereal can get lodged in ceding of Taiwan both sides influences operate as normal, even can damage the ceding of Taiwan.
Summary of the invention
The purpose of this utility model provides a kind of ratch structure of combine straw shift wheel, and the moving tooth at the two ends of this ratch structure can be harrowed the into ceding of Taiwan with the inboard cereal of piling up of nearside divider easily.
The utility model is achieved by the following technical programs:
A kind of combine straw shift wheel ratch structure, comprise and be distributed on the circumferential several ratch of straw shift wheel, fixedly connected with the straw shift wheel end plates respectively in described several ratch two ends, many elastic claws perpendicular to ratch have been arranged side by side on the ratch, described elastic claw is M shape, two straight flanges of described M shape vertically pass ratch, and M shape upper end is resisted against on the ratch; Described ratch two ends are symmetrical arranged at least one powerful moving tooth, and described powerful moving tooth one end is connected with the ratch vertical fixing, and described powerful moving tooth is parallel to elastic claw.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid combine straw shift wheel ratch structure, wherein said powerful moving tooth diameter is greater than the elastic claw diameter, and powerful moving tooth length is greater than elastic claw length.
Aforesaid combine straw shift wheel ratch structure, wherein said ratch two ends are symmetrical arranged a powerful moving tooth or two powerful moving teeth.
Aforesaid combine straw shift wheel ratch structure, wherein with several ratch that the end plates at straw shift wheel two ends are connected in, be symmetrical arranged two powerful teeth bar for dial teeth and be symmetrical arranged a powerful teeth bar for dial teeth and be arranged alternately.
The utility model is simple in structure, because the ratch two ends of straw shift wheel are symmetrical arranged one or two intensity higher strength moving teeth, though the cereal at ceding of Taiwan two ends is more than the cereal in the middle of the ceding of Taiwan, the ceding of Taiwan two ends inboard cereal of piling up of nearside divider is pushed in the ceding of Taiwan by powerful moving tooth at an easy rate during the straw shift wheel rotation, cereal can not piled up in ceding of Taiwan two ends, ceding of Taiwan operation is just more smooth and easy, has improved the operating efficiency of combine.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is one of structural representation of the present utility model;
Fig. 2 is two of structural representation of the present utility model;
Fig. 3 is the structural representation that the utility model is installed in straw shift wheel.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 1～shown in Figure 3, the utility model comprises and is distributed on the circumferential several ratch 2 of straw shift wheel 1, fixedly connected with straw shift wheel end plates 11 respectively in several ratch 2 two ends, the many elastic claws 3 that are M shape perpendicular to ratch 2 have been arranged side by side on the ratch 2, two straight flanges of M shape vertically pass ratch 2, and M shape upper end is resisted against on the ratch 2, and such structure is after elastic claw 3 damages, only need extract the elastic claw 3 of damage, the elastic claw 3 that just can more renew.Ratch 2 two ends among Fig. 1 are symmetrical arranged a powerful moving tooth 4, and ratch 2 two ends among Fig. 2 are symmetrical arranged two powerful moving teeth 4, and powerful moving tooth 4 is parallel to elastic claw 3, the one end pass with the weldering of the cross-drilled hole of ratch 2 thereon.Powerful moving tooth 4 diameters are greater than elastic claw 3 diameters, and powerful moving tooth 4 length are greater than elastic claw 3 length.The powerful moving tooth 4 of present embodiment adopts the low-carbon (LC) round steel of Φ 10mm to make, and elastic claw 3 adopts the carbon spring steel wires of Φ 5mm to make, and the strength and stiffness of powerful moving tooth 4 are all greater than elastic claw 3.In several ratch 2 that the end plates 11 at straw shift wheel 1 two ends are connected, the ratch 2 that has been symmetrical arranged the ratch 2 of two powerful moving teeth 4 and has been symmetrical arranged a powerful moving tooth 4 is arranged alternately, and is convenient to stir the inboard cereal of piling up of nearside divider.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
