Description
Technical field
The utility model relates to a kind of millet straw half feeding unit of feed reaper.
Background technology
At present, the development of grain header differs greatly in China each department.China Plain one band is as northern area, and grain header uses early, now replaces the heavy manual labor of peasant completely.And China mountain region, knob, because physical features is special, does not also realize the mechanization of farm work completely.Existing feed reaper, type is larger, and lays particular stress on, and is mainly suitable for the paddy field that physical features is smooth, become piece, and is difficult to transportation and walking for mountain region, knob, so be unsuitable for gathering in the paddy rice of this landform.
The structure that existing feed reaper is unsuitable in mountain region, the main cause of knob use is exactly semi-feeding type device is more complicated, makes feed reaper build greatly and Heavy Weight.Existing semi-feeding type device comprise be positioned at hold up the paddy rice conveying mechanism of standing grain wheel rear side, for clamping the clamping device of rice straw, for spike of rice being sent into the straw output mechanism after the sending into mechanism and threshing and complete of threshing cylinder threshing.Existing semi-feeding type apparatus structure complexity, the accuracy of manufacture requires high, has restricted the miniaturization of feed reaper.
Summary of the invention
The purpose of this utility model is to provide a kind of half feeding unit of feed reaper, is meeting under the prerequisite of functional requirement, and its structure is comparatively simple, can meet the requirement of the miniaturization of feed reaper.
Half feeding unit of feed reaper described in the utility model, comprise be positioned at hold up the paddy rice conveying mechanism of standing grain wheel rear side, for clamping the clamping device of rice straw, for spike of rice being sent into the straw output mechanism after the sending into mechanism and threshing and complete of threshing bin threshing, described paddy rice conveying mechanism is chain wheel conveyor structure, described clamping device comprises presses careless bar, this pressure grass bar is pressed on by elastic force on the chain of described chain wheel conveyor structure, press one end and the chain of careless bar to form straw arrival end, the other end and chain form straw outlet side; Describedly send into that mechanism comprises and the folding standing grain of engine interlock wheel, this folding standing grain wheel is positioned at the top of straw arrival end, and corresponding with the spike of rice entry position of threshing bin.
Further, described chain wheel conveyor structure comprises single backplate chain and the two backplate chains that are positioned at single backplate chain top; Described single backplate chain is arranged on the first drive sprocket and the first driven sprocket, is provided with spaced the first backplate of polylith at the outer surface of single backplate chain; Described pair of backplate chain is arranged on the second drive sprocket and the second driven sprocket, is provided with spaced the second backplate of polylith in upside and the downside correspondence of the outer surface of two backplate chains.
Further, described clamping device comprises presses careless bar, push rod, guide cylinder and Compress Spring, described push rod one end is fixed on presses on careless bar, the other end is arranged in guide cylinder, described Compress Spring is positioned at guide cylinder, Compress Spring one end is pressed on push rod end face, the other end is pressed on guide cylinder diapire, transmitting spring force by push rod makes to press careless bar to be pressed on the middle part of two backplate chains, press one end of careless bar to form straw arrival end with two backplate chains, the other end forms straw outlet side with two backplate chains.
When use, engine drives the first drive sprocket and the second drive sprocket to rotate by transmission mechanism, the first drive sprocket drives the first driven sprocket and single backplate chain movement, the second drive sprocket drives the second driven sprocket and two backplate chain movement, guarantees that single backplate chain is identical with the linear velocity of two backplate chains.After cutter cuts off rice straw, due to the constraint of the first backplate and the second backplate, rice straw after cutting off is positioned at the front side of single backplate chain and two backplate chains, and along with single backplate chain moves together with two backplate chains, in the time that rice straw moves to straw arrival end, rice straw bottom is clamp-oned and is pressed between careless bar and two backplate chain, under the effect of Compress Spring elastic force, realize the clamping to rice straw bottom, the rice straw being held is now positioned at the rear side of single backplate chain and two backplate chains, and continue motion under the effect of single backplate chain and two backplate chains, now, under the effect of folding standing grain wheel, the bending of rice straw top, spike of rice is stretched into and in threshing barrel, carry out threshing, in the time that rice straw moves to straw outlet side, threshing completes, rice straw is the constraint of pressurized grass bar not, under the effect of inertia, discharge from straw outlet side.
Half feeding unit of feed reaper described in the utility model, owing to thering is said structure, escort by single backplate chain and two backplate chain, press careless bar to realize the clamping to rice straw bottom, folding standing grain wheel has been realized spike of rice and has been stretched into threshing barrel, and single backplate chain and two backplate chain continue motion, after threshing completes, rice straw is the constraint of pressurized grass bar not, discharges from straw outlet side.This half feeding unit, simple in structure, transmission efficiency and functional reliability are higher, are applicable to being applied on the feed reaper of miniaturization.
