Abstract
The utility model relates to a corn threshing machine which comprises a frame, a hopper, a feeding inlet, a power drive mechanism, a threshing roller, a mesh screen structure arranged below the roller, a discharging hopper positioned below the mesh screen structure and a corncob outlet connected with the rear part of the mesh screen structure; the mesh screen structure is a rib screen presenting arc-shaped; the front part of the mesh screen structure is hinged with both sides of the frame, and the back part of the mesh screen structure is connected with an elastic piece; the elastic piece is fixed on the frame. The utility model has the advantages of reasonable structure, simple operation, low energy consumption, high efficiency and high threshing rate; the corn threshing machine is suitable for the threshing of corncobs.
Description
One, technical field
The utility model relates to agricultural thresher, is small-sized corn thresher specifically.
Two, background technology
Existing small-sized corn thresher has vertical, horizontal two kinds, and vertical corn thresher can only feed by hand one by one, and efficient is low.Horizontal shortage is effectively regulated, and reliable operation is bad.
That Chinese patent literature discloses is a kind of " husker sheller " (ZL02221817), the corn ear charging aperture is arranged on its frame, grain export, the knockout mouth mainly adopts threshing cylinder to make corn rod threshing, adopts mesh structure to separate seed and corncob.It structurally has following defective: the first, and the size of closing on the charging aperture of cylinder immobilizes, and can not change with the thickness of corn ear, influences threshing efficiency; It two is, the clearance constant of mesh structure and cylinder is constant, if the external diameter of corncob is bigger than normal, then can result in blockage, and corncob can not normally be discharged, and the influence operation is carried out continuously.
Three, utility model content
The purpose of this utility model is at prior art problems and weak point and a kind of husker sheller is provided, and the gap of mesh structure can be adjusted.This novel purpose is realized by following design: a kind of husker sheller; comprise frame, hopper, charging aperture, power-driven mechanism; threshing cylinder; place the mesh structure of cylinder below, be positioned at the mesh structure below go out the grain bucket and with the corncob outlet that the mesh structure rear portion joins, it is characterized in that; described mesh structure is curved rib sieve; its anterior and frame both sides hinge, the rear portion is crimped on the elastic component, and elastic component is fixed on the frame.
Described rib sieve rear portion is fixedly connected with otic placode, and described elastic component is a spring; Also have screw and nut on the frame of being fixed on, otic placode and spring are worn and are hung on the screw, and nut is positioned at the spring below.
Also be provided with rib type feeding adjustable plate on the anterior position of described threshing cylinder, its both sides, top and frame hinge, its underpart is fixed with two adjusting rods, this adjusting rod through the nut clamping on frame.
From technique scheme, this novel corn ear charging aperture governor motion that is provided with is because feeding adjustable plate top and frame are hinged, unclamp the nut on the adjusting rod, the level interval between itself and cylinder can be regulated, like this, the corn ear and the feed quantity adjustment of different sizes can be adapted to; Secondly, this novel employing rib sieve, and rib sieve front portion is hinged with frame, the rear portion is supported on the frame through spring, so, first can adjusting nut, change the spring height, thereby reach the size that changes the corncob outlet, to adapt to the variation of corncob size, second, the rib sieve supports through spring, spring self floats, and the corncob passage is blocked or stuck phenomenon can not take place again.
The utility model is compared with existing similar machine, has light, little, simple, honest and clean, firm characteristics, and the corn ear charging aperture can be regulated, and feeding speed improves, and the rib sieve has adaptivity and self-adjustment capability to the size of corncob.Regulatory function is rationally effective, can enhance productivity, and improves functional reliability.
Four, description of drawings
Fig. 1 is the stereogram of this novel embodiment;
Fig. 2 is the front view of threshing cylinder shown in Figure 1, feeding adjustable plate and rib sieve;
Fig. 3 is the vertical views of two threshing diagonal bars shown in Figure 1 on threshing cylinder.
Five, embodiment
Fig. 1 illustrates, and frame 9 is provided with hopper 1, and charging aperture (corn ear import) is arranged on the hopper, and the hopper end face has a platform (should be rectangle among the figure, because map format is big, remove an angle so dissect), to stack corn ear.Threshing cylinder 3 is located on the frame through bearing bracket stand, referring to Fig. 3, be welded with two straight muscle 3a of threshing on axial cross section of cylinder surface, its length equals drum length, on another axial cross section of 90 °, be welded with two threshing diagonal bar 3b that are angle (15-40 degree) with axis, charging aperture on the hopper extends downwards, the plate face is positioned on the anterior position of threshing cylinder by the rib type feeding adjustable plate 2 of round steel weldering system, feeding both sides, adjustable plate top and frame are hinged, its underpart is fixed with two adjusting rod 2a, this adjusting rod through the nut clamping on frame.Curved rib sieve 4 places cylinder below (not getting rid of other conventional mesh structure), and its front portion is hinged through axle 11 and frame both sides, and the rear portion is crimped on (as rubber, spring etc.) on the elastic component, and elastic component is fixed on the frame.Referring to Fig. 2, during this was novel, rib sieve rear portion was fixedly connected with otic placode 4a, and screw 10 is fixed on the frame, and otic placode and spring 5 (two groups) are worn and hung on the screw, and nut 10A is positioned at the spring below.There is grain bucket 7 rib sieve below, and rib sieve rear portion connects corncob outlet 6.The power-equipment of power-driven mechanism adopts motor (also available compact internal combustion engine), is fixed with motor bearing frame 8 on the frame, has the vertical and horizontal cylindrical void on it, so that regulate the rate of tension of driving belt.The rib sieve camber of threshing cylinder below, and gap, the place ahead is big between cylinder, and the gap, rear is little, and its gap is that (entering successively with material is preface) progressively dwindles from front to back.
Claims (6)
1, a kind of husker sheller; comprise frame, hopper, charging aperture, power-driven mechanism; threshing cylinder; place the mesh structure of cylinder below, be positioned at the mesh structure below go out the grain bucket and with the corncob outlet that the mesh structure rear portion joins, it is characterized in that; described mesh structure is curved rib sieve (4); its anterior and frame (9) both sides hinge, the rear portion is crimped on the elastic component, and elastic component is fixed on the frame (9).
