Abstract

The utility model relates to a stalk conveying device for a backpack corn combine harvester reaping both spike and stalks. In the stalk conveying device, two driving chain wheels are respectively installed at the left sides of two back feeding roll shafts, two driven chain wheels are respectively installed at the left sides of two front feeding roll shafts, a power output chain wheel is arranged at the right side of a lower back feeding roll shaft, each feeding roll shaft is connected with a corresponding transmission shaft by two flat keys and then installed between a left side board and a right side board, the left side board, the right side board, a bottom board and an upper cover are connected by bolts, an upper back feeding roll shaft and an upper front feeding roll shaft are connected into a group by a bearing seat, one end of a tension spring is installed on a tension spring seat on the left side board by a screw, one end of another tension spring is installed on a tension spring seat on the right side board by a screw, and the other ends of the tension springs are hung on and connected with shaft heads of the bearing seats. The characteristics of the structure is that the corn stalks are forcibly conveyed by the roll shafts and the roll shafts at the upper and lower layers and are completely destroyed so as to realize primary thermal treatment, the interval between the roll shafts and the roll shafts at the upper and lower layers can be automatically adjusted by the tension springs, and the stability and reliability of the stalk conveying device are ensured.

Description

A kind of stem stalk conveying plant that is used for corncob and stalk Backpack-type maize combined harvester

Technical field

The utility model relates to agricultural mechanical field, at a kind of stem stalk conveying plant of corncob and stalk Backpack-type maize combined harvester.

Background technology

Present existing corncob and stalk corn combined harvester great majority are that snapping bar is plucked fringe, and snapping bar is when winning fruit ear, and the stem stalk is dilatory downwards, is cut the chopping of stem cylinder, and intermediate link does not have stem stalk conveying plant; Because the corn stem joint is thick, and the broken joint effect of snapping bar is relatively poor, and do not passed through modifier treatment by the stem stalk of being left behind in the results process, the chopping effect is poor, can't satisfy the requirement as silage fodder.

Summary of the invention

The utility model has adopted double-deck roller to force the mode of force feed, finish stem stalk course of conveying, corn stem is by conveying plant the time, by broken fully joint, realized elementary modified, ready for follow-up chopping work, solved the problem that existing corncob and stalk corn combined harvester shreds weak effect preferably.

Technical solution of the present utility model is, this device is made up of housing and feeding roller two large divisions, after being contained in respectively, go up two drive sprockets on the left side spindle nose of feeding roll shaft under feeding roll shaft and the back, go up on the left side spindle nose of feeding roll shaft and the preceding roll shaft of feeding down before being installed in respectively by movable sprocket for two, power output sprocket is installed in the back right axle head of feeding roll shaft down, the feeding roller is gone up the feeding roll shaft with the back on the back, the feeding roller feeds roll shaft down with the back under the back, preceding feeding roller and the preceding feeding roll shaft of going up gone up, the preceding roller of feeding down is connected by two flat keys respectively with the preceding roll shaft of feeding down, be installed in then in the middle of left plate and the right plate, left plate, right plate, base plate, and loam cake is by bolt, nut connects, feeding roller and the preceding feeding roller of going up are linked as one group by bearing block on the back, extension spring one end is installed on left plate and the right plate extension spring seat, the other end is articulated on the spindle nose of bearing block, the preceding feeding roller and the preceding feeding roller down gone up of this structure, the feeding roller can be regulated by extension spring in the gap of feeding roller down automatically with the back on the back, to adapt to different stem stalk feed quantities, guarantee the reliable and stable and stronger adaptability of stem stalk conveying plant.
