Abstract
A kind of longitudinal axial flow all feeding-in combine threshing stalk smashing apparatus with broken careless function, the threshing cylinder of device is the cylindricality full-open type ratch cylinder of two sections, front and back series connection, leading portion diameter of cylinder is less than back segment diameter of cylinder, and 2 or 3 pieces of spiral deflectors are housed, on back segment drum ratch except being welded with threshing tooth, Lysimachia sikokiana tooth, also cutting grass knife can be installed.The notch board matched with cylinder is steel plate two sections of combined type concave plates welded after front grid, and the steel plate section of notch board can install the U-shaped stationary knife matched with cutting grass knife.Through the present invention of above-mentioned improvement, due to just add before roller forage discharging dynamic, determine cutting grass knife, stalk spin backward motion in repeatedly shredded, even if device not only has threshing function and also has powerful broken careless function outward, because cutting grass knife is directly installed on ratch, therefore linear velocity is identical with threshing tooth, far below tradition, plug-in or lower hanging straw millstone, greatly reduces vibration and namely adds reliability.
Description
Technical field
The present invention relates to a kind of longitudinal axial flow all feeding-in combine sheller unit with broken careless function.
Background technology
Along with the appearance of national environmental protection policy, peasant's direct-fire is not allowed to burn the rear remaining straw in the ground of harvesting, and the sheller unit of existing longitudinal axial flow all feeding-in combine does not have broken careless function, so each manufacturing enterprise is the plug-in or lower straw millstone having hung a High Rotation Speed with regard to the numerous and confused straw outlet at product, but because this device rotary speed is high, vibrations are large, big energy-consuming, efficiency are low, transmission is complicated and it is always not ideal enough also to there is many unsafe factors etc.
Summary of the invention
Object of the present invention, is to provide a kind of longitudinal axial flow all feeding-in combine sheller unit with broken careless function, and device not only has threshing function to also have broken careless function, and device rotary speed is far below traditional plug-in or lower hanging straw millstone.
Technical solution of the present invention is: comprise and be installed on horizontal threshing cylinder in threshing room of combine and concave grate, threshing roller structure is cylindricality full-open type and two sections of point tandem, leading portion is short in feeding, rear segment length is used for threshing, broken grass and Lysimachia sikokiana, two Length Ratios are 1: 4 ~ 5, and leading portion diameter is less than back segment 10 to 35 millimeters; Concave sieve structure be leading portion adopt steel wire interval equal or front dredge after close full lattice structure and back segment adopt the combined type of punching steel plate structure, combining structure length ratio is 6 ~ 8: 1.
The leading portion ratch number of described threshing cylinder is 4 or 6 and back segment ratch number is 3,4 or 6, and can be arranged on respectively on the discs of front and back cylinder, connection is circumferentially symmetrical, uniform.
Described leading portion ratch be welded with feeding tooth and back segment ratch be also welded with except being welded with threshing tooth chaffcutter tool rest and Lysimachia sikokiana tooth, chaffcutter tool rest having 1 ~ 3 through hole or screw can installing cutting grass knife or threshing board tooth.
The feeding tooth of described leading portion ratch is plate toothing, plate tooth plane torsion certain angle, lower plane has a hole for ratch through rear welding, and after seam, upper plane becomes certain inclination angle with ratch axis, through hole or screw that upper plane has 1 to 3 to be convenient to select to install spiral deflector.
Apart from outside the installing hole corresponding with chaffcutter tool rest in the middle of described cutting grass knife, below also has one to be stuck in breach on ratch, strong turning moment suffered during to alleviate chaffcutter.
On described back segment punching notch board, there are elongated slot and circular hole in the hole rushed, circular hole be used for seed through and elongated slot for installing some stationary knifes to coordinate the broken grass of threshing cylinder.
The invention has the beneficial effects as follows: crop grabs into threshing limit, limit for the helical movement backward by cylinder leading portion by force that be welded with feeding tooth, crop seed after abundant threshing falls into cleaning plant through notch board and stalk is repeatedly shredded under the threshing toothed bar being provided with cutting grass knife coordinates with the notch board being provided with some stationary knifes, after overcoming classical joint harvester threshing drum straw outlet, the stalk smashing apparatus single of extension or lower hexagram shreds and necessary disadvantage at a high speed, both reduce power consumption and again saved space, also greatly increases the reliability of device, safety.
