Description
Technical field
The present invention relates to a kind of grain machine of feeding, especially relate to a kind of semi-feeding type thresher.
Background technology
Common half-feeding combine threshing concave plate is that grid type, cross section are circular shapes; Notch board is made up of horizontal Turbogrid plates and vertical steel wire; Be fixed on the threshing body; Easy blocking when threshing, because the unusual difficulty of the cleaning that receives the spatial constraints notch board, notch board easy blocking more when taking off moist crop especially.Like publication number is that the Chinese patent of CN101940109 discloses a kind of novel threshing concave plate sieve that partly feeds; Constitute by sieve plate and the dividing plate that is used to separate sieve plate; It is characterized in that described sieve plate is formed by connecting stamped sieve and grid screen; Wherein stamped sieve is located at feeding mouth one side, and described sieve plate total length is 1/2 to 3/5 of a corresponding threshing cylinder girth, and described stamped sieve is 2/3 to 3/2 with the area ratio of grid screen.This notch board plug is easy to occur blocking problem, and once appearance is stopped up, can only stop operation, the labor cleaning, and this scale removal process not only bothers, but also exists very big potential safety hazard.Publication number is that the Chinese patent of CN201919356 discloses a kind of thresher with anti-clogging function; Comprise frame, threshing case, actuating unit, be provided with threshing cylinder in the threshing case, the downside of threshing cylinder is provided with concave grate; It is characterized in that described concave grate is made up of preceding notch board and back notch board; Forward and backward notch board is hinged, and preceding notch board and frame fix, and back notch board links to each other with frame through elastic mechanism.This structure can play the effect of stopping up of preventing to a certain extent, and still, it is a kind of passive anticlogging device; Only after it stops up to a certain degree; This anticlogging device just works, and it is big to work as the amount of stopping up, when the obstruction process is rapid; When the effect meeting very little, almost do not reach the effect that prevents or clear up obstruction.
Summary of the invention
The present invention solves existing in prior technology to prevent that the functional effect that stops up is bad; Can not in time initiatively clear up the technical problem of tamper; Provide a kind of and can initiatively clear up stalk, and can promote the threshing concave plate that partly feeds sheller unit of the rapid separation of grain.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: a kind of threshing concave plate that partly feeds sheller unit; Constitute by the cylinder grid; It is characterized in that described cylinder grid comprises along several arc tracks of the axially-aligned of threshing cylinder; The downside at arc track two ends is respectively equipped with a corresponding each other sprocket wheel, and two corresponding each other sprocket wheels are linked to each other by an adaptive with it chain, the adaptive and corresponding arc track downside of described chain; Be in series through some connecting rods between chain and the chain; The same side sprocket wheel is in series through a rotating shaft, and wherein the rotating shaft of a side is power input rotating shaft, and the rotating shaft of opposite side is a driven spindle.In the course of work of this head-feed threshing unit; Power input rotating shaft is rotated under the driving of drive unit; Drive each drive sprocket and rotate or back and forth rotate, and then drive each chain movement, chain is in motion process; Its side sections is moved along arc track, goes into the notch board grid in the continuous motion.It has quickened grain on the one hand and has dropped from the notch board grid, has improved the percentage of thresh and threshing efficiency; Also drive the crushing straw motion on the other hand, it can be blocked between threshing concave plate and the grain threshing roller.
As preferably, the two ends of described arc track are provided with the circular arc guided way, and this circular arc guided way and described sprocket wheel are suitable, are provided with described chain between itself and the sprocket wheel.The effect of circular arc guided way is in order to improve the guidance quality of chain on the one hand; Also be for chain and sprocket wheel are protected on the other hand; Prevent that grain, broken grass etc. from entering between chain and the sprocket wheel, it is damaged, influence its operate as normal and service life.
As preferably, described arc track interconnects through several dead levers, and the arc track that is in the rear and front end links to each other with threshing bin.
As preferably, be rotationally connected between described connecting rod and the described chain.In use, understand owing to operating error, mismachining tolerance between each chain, and the reasons such as twisting of rotating shaft; Cause the deviation of the position between connecting rod and the chain, can find out, under above-mentioned this situation by work characteristics of the present invention; Connecting rod can be found certain twisting; This twisting more greatly, the burden of more frequent then driving mechanism is big more, and energy consumption is big more, and also the infringement to itself is big more simultaneously.After employing between connecting rod and the chain was rotationally connected, its twisting did not almost have.Therefore this programme effectively raises energy utilization ratio, has protected connecting rod and driving mechanism.
As preferably, described power input rotating shaft links to each other with a turbine, and this turbine and a scroll bar are suitable, and scroll bar passes through belt wheel and links to each other with power set.
The beneficial effect that brings of the present invention is; Solved existing in prior technology and prevented that the functional effect that stops up is bad; Can not in time initiatively clear up the technical problem of tamper; Realized a kind ofly can initiatively clearing up stalk, and can promote the threshing concave plate that partly feeds sheller unit of the rapid separation of grain.
