Abstract
The utility model discloses a grass-tangling-proof device for driven sprockets of a conveying trough of a harvester. The grass-tangling-proof device comprises a cylinder combination, two driven sprockets, a sprocket support mandrel and grass covers, wherein the driven sprockets are symmetrically disposed at two ends of the sprocket support mandrel and movably connected with the sprocket support mandrel through bearings, the grass covers are arranged at outer ends of short cylinders, the outer ends of the grass covers are fixedly connected with support boards, and two ends of the sprocket support mandrel are respectively fixed to the support boards. A baffle board is disposed between the inner side of each support board and the radial outer side of the corresponding grass cover and positioned on an extension face of a horizontal central radial plane of the grass cover, and the longitudinal outer side and the transverse outer side of each baffle board are respectively fixedly connected with the corresponding support board and the corresponding grass cover. Equivalently, the diameter of each grass cover is enlarged, namely grass tangling circumference is enlarged, the circumference is far larger than the length of higher crops to be harvested, the higher crops cannot be knotted and tangle to a roller end to end, and thereby normal operation of the conveying trough of the harvester is guaranteed.
Description
Technical field
The utility model relates to a kind of grain header delivery chute by movable sprocket, and especially a kind of grain header delivery chute is prevented twining careless device by movable sprocket, belongs to agricultural machinery technological field.
Background technology
The track combine delivery chute adopts the chain-and-harrow type conveying plant usually, drive chain operation by the master who is installed in the delivery chute upper and lower side, follower, the rake teeth bar is installed on the chain, when the ceding of Taiwan is delivered to the delivery chute lower port with the crop that extracts, promptly is transported to threshing chamber and carries out threshing by the rake teeth extracting.The defective of this device is, when crop lodging or crop were higher, two to be twined grass by the movable sprocket outside cylindrical serious, influenced the operate as normal of delivery chute.At the problems referred to above, prior art adopt to strengthen by the drum diameter in the movable sprocket outside, makes its girth lengthening, when crop length less than by the girth of movable sprocket outside cylindrical the time, crop can't be wrapped on the outside cylindrical.But owing to be subjected to the restriction of delivery chute structure, amplitude by movable sprocket outside cylindrical enlarged diameter is limited, the excessive overall weight that increases track combine of drum diameter, increased crawler belt combine grounding pressure, the manufacturing cost height is difficult to satisfy the heavy burden requirement of track combine.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, cost is low, can effectively avoid crop to be wrapped in by the grain header delivery chute follower on the movable sprocket outside cylindrical is anti-twines careless device.
The utility model is achieved by the following technical programs:
A kind of grain header delivery chute is twined careless device by movable sprocket is anti-, comprises that cylinder combination, two supported axle, retaining straw mulch by movable sprocket, sprocket wheel, describedly is symmetricly set on described sprocket wheel by movable sprocket and supports the axle two ends, supports the axle flexible connection by bearing and sprocket wheel; The combination of described cylinder comprises and is supported on two by the long cylinder between the movable sprocket, be set in two by the short cylinder in the movable sprocket outside, described short cylinder outer end is provided with the retaining straw mulch, fixedlys connected with gripper shoe in described retaining straw mulch outer end, and described sprocket wheel supports the axle two ends and is separately fixed on the gripper shoe; Described gripper shoe inboard with retaining straw mulch radial outside between a baffle plate is set, described baffle plate is positioned on the extended surface of sagittal plane, horizontal center of retaining straw mulch, the baffle plate vertically outside is fixedlyed connected with gripper shoe, the baffle plate lateral outer side with keep off straw mulch and fixedly connected.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid grain header delivery chute is prevented twining careless device by movable sprocket, and wherein said baffle plate is made with steel plate.
The utility model is simple in structure, and cost is low.Support the retaining straw mulch outside at axle two ends at sprocket wheel and respectively set up a baffle plate, this baffle plate side is positioned on the extended surface of the central horizontal sagittal plane that keeps off straw mulch, be equivalent to strengthen the diameter of retaining straw mulch, the retaining straw mulch girth that strengthens much larger than harvesting than high crop length, can not tie a knot from beginning to end than high crop is wrapped on the cylinder, thereby has guaranteed the operate as normal of grain header delivery chute.
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 a structural representation of the present utility model;
Fig. 2 is the B-B amplification view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the utility model comprises that cylinder makes up 1, two by movable sprocket 2, sprocket wheel support axle 3, retaining straw mulch 4, be symmetricly set on sprocket wheel by movable sprocket 2 by bearing 7 and support the axle two ends, sprocket wheel supports axle 3 two ends and is separately fixed on the gripper shoe 5; Cylinder combination 1 comprises and is supported on two by the long cylinder between the movable sprocket 2 11, is set in two by the short cylinder 12 in movable sprocket 2 outsides, and short cylinder 12 outer ends are provided with retaining straw mulch 4, and cylinder combination 1 is rotated by movable sprocket 2 with two.Retaining straw mulch 4 is bowls that axial flange is arranged, fixedly connected with gripper shoe 5 in its outer end, between gripper shoe 5 inboards and the retaining straw mulch 4 axial flange baffle plate 6 is set, described baffle plate 6 is positioned on the extended surface of the sagittal plane, horizontal center that keeps off straw mulch 4, and two adjacent vertical outside and lateral outer side of baffle plate are weldingly connected with gripper shoe 5, retaining straw mulch 4 respectively.
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.
