Abstract

The utility model relates to a conveying apparatus of a combine harvester, which aims to provide a conveying apparatus of a combine harvester. The conveying apparatus can continuously work for a long time, and a rotary shaft can not wind rice straws when the conveying apparatus works. The utility model comprises a transmission chain, a driving shaft unit and a driven shaft unit, wherein the driving shaft unit and the driven shaft unit are both comprises rotary shafts, bearings, bearing seats and chain wheels. The utility model is characterized in that the driving shaft unit and the driven shaft unit are provided with straw winding preventing sleeves, and free sleeves are sheathed on the rotary shafts between the two chain wheels. Because the rotary shafts of the utility model can not be directly contacted with rice straws, the rotary shafts can not wind the rice straws and the combine harvester can not stop working to clear the wound rice straws. The utility model has the advantages that the combine harvester can continuously work for a long time, the work efficiency is improved, the abnormal wear of components, such as the rotary shafts, the bearings, etc., is reduced and the service life of the parts is extended.

Description

A kind of conveyer of combine

Technical field

The utility model relates to the conveyer of a kind of combine, particularly a kind of combine.

Background technology

Combine is an agricultural machinery comparatively commonly used now.Combine is in when work, and the task that conveyer is responsible for is the next working link that the crops such as rice wheat of cutting off is sent to combine, threshing apparatus for example, the effect after whole harvesting work is played brought forward and connect.The conveyer of existing combine is owing to the reason in the design, have the following disadvantages: the transmission turning cylinder of traditional combine conveyer exposes, just turning cylinder is directly to contact with the rice straw of being cut off when work, because turning cylinder directly contacts with the rice straw, turning cylinder must twine the rice straw when rotating, resistance in the time of can increasing the turning cylinder rotation so greatly, after combine work a period of time, just must quit work, the rice straw that is wrapped on turning cylinder and the bearing is removed, otherwise will be caused the inordinate wear of parts such as bearing.The conveyer of therefore traditional combine can't long time continuous working, has reduced the operating efficiency of combine, also has the shortcoming of part inordinate wears such as bearing simultaneously, the service life of reducing these parts.

Summary of the invention

Turning cylinder can not twine the combine conveyer of rice straw when the purpose of this utility model was a kind of energy long time continuous working, work are provided.

A kind of conveyer of combine, comprise driving-chain, driving shaft group and driven axle group, driving shaft group and driven axle group all comprise turning cylinder, bearing, bearing block and sprocket wheel, it is characterized in that described driving shaft group and driven axle group are provided with the anti-grass cover that twines, and are with freely on the turning cylinder between two sprocket wheels and overlap.

The described anti-grass that twines is socketed on the turning cylinder, and is connected with bearing block.

The described anti-grass that twines is socketed on the turning cylinder, and is connected with casing.

The beneficial effects of the utility model are: because turning cylinder of the present utility model does not directly contact with the rice straw, turning cylinder can not twine the rice straw, can not cause the combine interruption of work to remove the rice straw that twines, combine is worked long hours continuously, improve operating efficiency; And reduce the inordinate wear of parts such as rotating shaft, bearing, increase the service life of part.

Wherein 1. turning cylinders among the figure, 2. sprocket wheel, 3. bearing block, 4. bearing, 5. anti-ly twine that grass overlap, 6. freely overlaps, 7. driving-chain, 8. conveying jaw.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of conveyer of combine, comprise driving-chain 7, driving shaft group and driven axle group, the conveyer of combine is to be used for transmitting the rice straw the cut off next equipment to combine, the threshing apparatus of combine for example, need drive the rice straw of carrying jaw 8 to be cut off by active and passive two axle groups and be sent to threshing apparatus, driving shaft group and driven axle group all comprise turning cylinder 1, bearing 4, bearing block 3 and sprocket wheel 2, driving shaft group and driven axle group all are provided with the anti-grass cover 5 that twines, be with on the turning cylinder 1 between two sprocket wheels 2 and freely overlap 6, the anti-grass cover 5 that twines can be socketed on the turning cylinder 1, and with 3 firm connections of bearing block, the anti-grass cover 5 that twines can also be socketed on the turning cylinder 1, and is connected with casing.

As shown in Figure 1, when the combine conveyer is worked, rotating shaft 1 is rotated, sprocket wheel 2 is connected in the rotating shaft with rotating shaft 1 and rotates, and the anti-grass cover 5 of twining is connected with bearing block 5 or casing, with turning cylinder 1 rotation, freely overlapping 6 is socketed between two sprocket wheels 2, do not fixedly connected, therefore do not rotate yet, do freely to rotate but can relatively rotate axle 1 with turning cylinder 1 with any parts.Such design make turning cylinder 1 and rice straw by anti-twine grass cover 5 and freely overlap 6 separate, the rice straw can not curl on turning cylinder 1, harvesting work energy long-time continuous is carried out, and has increased the service life of bearing, turning cylinder effectively yet.

Claims

1. the conveyer of a combine, comprise driving-chain, driving shaft group and driven axle group, driving shaft group and driven axle group all comprise turning cylinder, bearing, bearing block and sprocket wheel, it is characterized in that described driving shaft group and driven axle group are provided with the anti-grass cover that twines, and are socketed with freely on the turning cylinder between two sprocket wheels and overlap.

2. the conveyer of combine according to claim 1 is characterized in that the anti-grass that twines is socketed on the turning cylinder, and is connected with bearing block.

3. the conveyer of combine according to claim 1 is characterized in that the anti-grass that twines is socketed on the turning cylinder, and is connected with casing.
