Abstract

The utility model relates to an improved combine harvester cutting table. Grain dividers are arranged at the front parts of two sides of a stand; a grain pulling wheel is arranged on a rack which is articulated with the stand; a moving blade and a fixed blade are arranged at the front edge of a working table and inside the stand; a feeding spiral conveyer is arranged on the working table; a transmission device which is used for transmitting a spiral conveyer and the grain pulling wheel is arranged at the left side of the stand; movable grain dividers which are separated from the stand is arranged at front part of the right side of the stand; the movable grain dividers are articulated with the right side of the stand; a cylinder body of an oil cylinder is hinged at the right side of the stand; and the front end of a piston of the oil cylinder is articulated with the outer side of the grain dividers. The combine harvester cutting table has simple structure and reliable performance, can reduce the occurrence frequency of lying over crops significantly and avoids blockage of crops when working so that the working efficiency of the combine harvester is further improved.

Description

Improved combine harvester cutting table

Technical field

The utility model relates to the reaping apparatus on the combine, specifically a kind of ceding of Taiwan of combine.

Background technology

The front portion of the various wheat and rice combine harvester ceding of Taiwan upper spiders left and right sides on the existing market is equipped with the nearside divider that front end is taper, but the nearside divider that is provided with all fixes again, and promptly left and right nearside divider is an one with frame all.The nearside divider of frame both sides and frame are that a global existence following deficiency: 1, when grain header is turned right greatly in farm work, fixing nearside divider can overwhelm the crops that a part is not gathered in as yet, and this part crops that strikes the beam then can't be gathered in by grain header again; 2, the swath of grain header is to determine that by the distance between the nearside divider of the left and right sides fixing nearside divider has caused swath to regulate; 3, grain header is in the harvesting of field, and when the lodging of crops, field was serious, the crops of close nearside divider inboard, right side can form the stifled phenomenon of more serious heap soil or fertilizer over and around the roots between nearside divider and straw shift wheel and cutter, can cause when serious and can't continue operation.

The utility model content

The purpose of this utility model is to provide a kind of improved combine harvester cutting table device, when in harvester operation, turning right greatly, its can be the least possible overwhelm the crops, and it can realize swath to a certain extent adjustment and avoid the heap soil or fertilizer over and around the roots of crops between nearside divider and straw shift wheel to block up phenomenon.

For achieving the above object, the utility model adopts following scheme: improved combine harvester cutting table, the front portion of frame both sides is connected with nearside divider respectively, with on the hinged support of frame straw shift wheel is housed, forward position at the workbench of frame inboard is provided with knife section and ledger-plate, on workbench, be provided with screw feeder, the frame left side is provided with and is used for transmission screw feeder and reel drive, front portion, frame right side is connected with the movable nearside divider with its split, movable nearside divider and frame right side are hinged, the cylinder body of one oil cylinder is hinged on the right side of frame, and the piston rod front end of oil cylinder and the outside of movable nearside divider are hinged.Oil cylinder is connected with the hydraulic system of grain header, and will controls that oil cylinder advances, the device of oil return is installed in the driver's cabin of grain header, it is flexible to control the oil cylinder piston bar by the driver, i.e. the rotation of control activity nearside divider.

By such scheme as seen, because the discharge end of combine is in the left side, therefore combine all is to travel along the right side in farm work, and also bend to right when turning, when combine is turned right in the field, the manipulation activities nearside divider also rotates it thereupon to the right, and so movable nearside divider will be the least possible overwhelms the crops; And adjustment activity nearside divider can be adjusted swath to the open angle in the ceding of Taiwan outside; In addition, movable nearside divider is opened to the ceding of Taiwan outside, the space between can increase activity nearside divider inboard and straw shift wheel and the cutter avoids the crops to block up phenomenon in the interior heap soil or fertilizer over and around the roots in this zone.

Simple in structure, the dependable performance of the utility model, it can significantly reduce the phenomenon that the crops strikes the beam, and it the time can avoid the stifled phenomenon of heap soil or fertilizer over and around the roots in crops in work, thereby the operating efficiency of combine is further improved.

Description of drawings

The structural representation of Fig. 1 the utility model one embodiment;

The vertical view of Fig. 2 Fig. 1.

Embodiment

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1, the improved combine harvester cutting table that the utility model provides is equipped with straw shift wheel 4 on the hinged support 2 of its frame 1.Referring to Fig. 2, the front portion in frame 1 left side is connected with nearside divider 7, nearside divider 7 is an one with frame 1, forward position at the workbench 12 of frame 1 inboard is provided with knife section 8 and ledger-plate 9, on workbench 11, be provided with screw feeder 13, be provided with the transmission device 14, the transmission device 15 that are used for transmission screw feeder 13 and straw shift wheel 4 in the left side of frame 1.More than same as the prior art.

Referring to Fig. 1, Fig. 2, front portion, frame 1 right side is connected with the movable nearside divider 5 with its split, and movable nearside divider 5 is hinged with frame 1 right side, and the cylinder body of an oil cylinder 6 is hinged on the right side of frame 1, and the piston rod front end of oil cylinder 6 and the outside of movable nearside divider 5 are hinged.Handle oil cylinder 6, its piston rod is moved back and forth, rotation that can realization activity nearside divider 5.

Be hinged with a sleeve 10 on the inboard of movable nearside divider 5, be hinged with a fork 11 on a ledger-plate 9 of the most close movable nearside divider 5, fork 11 stretches in the sleeve 10.When movable nearside divider 5 rotated, fork 11 and sleeve 10 also can rotate, and fork 11 can relatively move with sleeve 10.Being provided with of fork 11 and sleeve 10 can be played guiding function to the crops.In addition, do not stop up stifled phenomenon for better not occurring the crops between assurance activity nearside divider 5 and the straw shift wheel 4, distance between the medial surface on the framework 4a on straw shift wheel 4 right sides and frame 1 right side is 20～30cm, and promptly the inside sidesway 20～30cm of the framework 4a on straw shift wheel 4 right sides is good.
