Description

The device that is used for cereal conveying and threshing

The present invention relates to a kind ofly be applicable to that cereal is carried and the device of threshing, particularly the present invention relates to a kind of device that clamps the conveying grain threshing, the invention still further relates to and take off thing and can enter easily and take off separator again.

The threshing main purpose of cereal is that the seed of cereal is separated from cane, is convenient to store and utilize.Day the present invention and use clamping partly feed threshing apparatus, cut off the cereal cane earlier, discharge by the other end again after feeding threshing by clamping device clamping cereal stem by threshing cylinder one end again, the clamping device that is adopted is to be made of toothed chain and grass pressing board, toothed chain clamping cereal slides on the grass pressing board face, to enter sheller unit be not possible to the cereal integral body that is compressed by grass pressing board, this gives to take off again to separate and makes troubles, also have an inconvenience by the length of the thickness of shelling thing layer less than the threshing tooth, the cereal layer thickness surpasses the cereal of threshing tine length will can not taken off seed.In order to solve the existing inconvenience of the said equipment, on threshing apparatus, adopt checkout gear, as patent of invention, 90104403.2 of application numbers are called threshing apparatus, its included cane charging checkout gear that is used to detect threshing cylinder cane inlet amount and one are used for regulating from the separation bubble of the separation bubble flow of blower fan with the variation of cereal cane quantity and reconcile device, and this checkout gear can be controlled the threshing apparatus that is adopted and be in normal operating conditions.Therefore also need further to improve the existing inconvenience of the said equipment.

The object of the invention provides the device of a kind of cereal conveying and threshing, and this device can be controlled cereal integral body effectively and enter threshing chamber.

The object of the invention provides that a kind of cereal is carried and the device of threshing, when this installs normal threshing, and can be by shelling thing layer thickness above several times of threshing tine length.

The object of the invention provides that a kind of cereal is carried and the device of threshing, during this device threshing by shelling thing layer or approach or when thick, threshing performance all is significantly improved.

In order to realize this purpose, the inventive system comprises a conveying plant and a sheller unit, conveying plant places a side of sheller unit, be that a fringe portion by the shelling thing can feed, take off the opening that the cane behind the seed can be discharged on the housing between conveying plant and the sheller unit, conveying plant is by equidistant several grass-trap teeth of arranging on the chain that places carrier chain, places several grass pressing boards that grass-trap tooth one side is rotatably connected from beginning to end and place grass-trap tooth opposite side, and the limiting plate of the feeding end of threshing cylinder constitutes.Described carrier chain is to be made of the chain around drive sprocket and passive sprocket rotation, is the break-in deceleration transmission between drive sprocket and the sheller unit power take-off.One end of the connecting rod of described each grass pressing board and an outer casing spring is rotatably connected, and the other end of connecting rod and framework are for flexibly connecting, and the two ends of described spring contact with the junction respectively.Fringe portion sheller unit that sheller unit is made up of the housing of threshing cylinder, threshing tooth and double as spigot surface and answering of taking off that tooth, hole sizer and housing form by re-threshing roller, are again taken off separator and are constituted.Described threshing cylinder and re-threshing roller place on the same axis, its junction is fixedly connected, and any one the threshing tooth on the threshing cylinder has the minimum diameter of the space that forms together of several threshing teeth and this threshing tooth less than cereal kernel in rotating a circle.Cereal places on the chain of motion between the adjacent two grass-trap teeth, haul the cereal motion by the grass-trap tooth, the stem of cereal is compressed by bending at position of grass-clamping tooth under the resistance control of grass pressing board and limiting plate, grain tassel part moves in the process of opposite side at the threshing zone that tooth top and tooth root by threshing cylinder one side threshing tooth on threshing cylinder form, the threshing tooth that is rotated is taken off seed, takes off thing and is entered by the housing of double as spigot surface guiding and take off separator again.Take off the axial flow impeller on the re-threshing roller in the separator again, the fixedly ring washer on rotating ring washer and being fixed on hole sizer takes off thing with control and separates taking off again to take off again in the separator, take off the long shoot bar of seed and discharged by straw outlet, seed and short and small foreign material enter the separator that air-flow and vibratory sieve are formed by the mouth of putting out cereal.

Below in conjunction with accompanying drawing to the detailed description of the invention.
