Abstract
The invention relates to a harvester for standing crop: corns. In order to solve the technical problems that the present standing grain-shifting chain of the corn harvester easily looses and drops, and the tightness adjustment of the present standing grain-shifting chain is not easy to master. The invention provides an automatic takeup for the standing grain-shifting chain of the corn harvester. In the takeup, a long notch is arranged at a position below the installation position of a driven sprocket, an upper sliding panel is arranged above the notch, a lower sliding panel is arranged below the notch, a driven sprocket shaft penetrates through the notch and shaft holes in the upper sliding panel and the lower sliding panel, and the upper sliding panel and the lower sliding panel can drive the driven sprocket shaft to move back and forth in the notch. One end of the upper sliding panel, which is far away from the driven sprocket, is bent upwards to form a pressing end, a fixing pressing block is arranged on a position of a header, where the pressing end extends to a drive sprocket, and a supporting spring is arranged between the pressing end and the fixing pressing block. According to the invention, the adjustment is not required to be carried out again after the tightness of the standing grain-shifting chain is debugged in one step during assembly, and the smooth operation of the corn harvester can be ensured.

Technical field
The present invention relates to the harvest machinery of standing crop corn, specifically be meant maize harvesting machine rice-pulling chain automatic takeup.
Background technology
At present, the standing grain device of dialling of maize harvesting machine is fixed on the header of maize harvesting machine, when maize straw is stirred stalk it is entered among the ear-picking unit by dialling the standing grain device.Dialling the standing grain device is at the fixing driven sprocket of the front end of header; Fixing one group of standing grain device drive sprocket in the rear end of header; Adopt chain drive between drive sprocket and the driven sprocket, fixing bat on chain, the power that passes to drive sprocket through the complete machine dynamical system drives the rotation of chain and driven sprocket; When chain rotated, the bat on it was realized stirring of stalk.
But find that in practical application adopt the chain drive pattern, the chain that turns round for a long time can relax, chain can be by coming off on the sprocket wheel when having served as pine, promptly common people's said " chain-taking ".When this thing happens, operating personnel had to shut down adjustment and the installation of carrying out chain, and the elasticity of chain adjustment is difficult for grasping, and crossed loose chain and were prone to come off, and tension then influences the running of chain, sprocket wheel.So not only delayed the production time, also brought certain maintenance task to operating personnel.
Summary of the invention
Be prone to relax, fall chain and the not wield technical problem of elasticity adjustment for overcoming present maize harvesting machine rice-pulling chain, the present invention provides maize harvesting machine rice-pulling chain automatic takeup.
The technical scheme that the present invention adopts is: maize harvesting machine rice-pulling chain automatic takeup, and this device comprises the driven sprocket that is arranged on the header front end, is arranged on the drive sprocket of header rear end; Driven sprocket and drive sprocket adopt rice-pulling chain to realize rotating, fixing bat on rice-pulling chain, and it is characterized in that: described header is provided with microscler notch below the driven sprocket installation site; Notch is parallel with the rice-pulling chain rotation direction; One upper sliding plate is set above notch, sliding panel once is set below notch, slide up and down plate up and down correspondence position be respectively equipped with axis hole; The driven chain wheel shaft runs through notch and slides up and down the axis hole on the plate; Fixed by nut is adopted in its lower end, and driven sprocket is installed in the upper end, slides up and down plate and can drive the driven chain wheel shaft and in notch, move forward and backward; Described upper sliding plate is upwards turned up to form away from an end of driven sprocket and is compressed end, the fixing piece that supports is set compressing end on the header on the position that drive sprocket extends, and compresses end and between the piece support spring is installed with fixing.
Slide up and down plate and can be reposefully slide for making along the notch upper and lower surfaces, described slide up and down plate up and down correspondence position be respectively equipped with stable hole, stable bolt passes notch and stable hole up and down, fixed by nut is adopted at its two ends.
Slide up and down plate and can move forward and backward along the rice-pulling chain rotation direction for making, below the upper sliding plate axis hole, be provided with the axis hole boss, this boss is embedded among the notch.
The below of stable hole is provided with the stable hole boss on the described upper sliding plate, and this boss is embedded among the notch.
Elastic force size for convenient adjustment support spring is provided with screw rod fixing supporting between piece and the support spring, and the fixing piece that supports is provided with the inner chamber that has internal thread, and screw rod passes the fixing inner chamber that supports piece.
Beneficial effect of the present invention: owing to below driven sprocket, be provided with notch; Driven sprocket forms " floating " state; With the variation of rice-pulling chain rotation direction, speed, driven sprocket can move forward and backward under the effect of support spring, thereby has realized the effect of rice-pulling chain auto-tensioning.This utility model is rational in infrastructure, and is easy for installation, and the tightness of rice-pulling chain need not be adjusted after when assembling, once debugging once more, can guarantee the smooth and easy operation of maize harvesting machine, has reduced operating personnel's maintenance task.
