Description

Dislocation formula maize cleaning plant

Technical Field

The invention relates to a staggered corn cleaning device, and belongs to the technical field of agricultural machinery.

Background

The current corn grain cleaning mechanism is mostly plane reciprocating vibration, the motion form is comparatively single, and the sifter is mostly the plane sieve, can only realize the one-dimensional sieve that passes of corn grain, and when cleaning the great or material moisture content of mechanism feeding volume, the material is difficult for the dispersion, adheres at the sifter easily, piles up, blocks up the sieve mesh, leads to the operating efficiency to reduce, cleans the effect and cleans the quality relatively poor.

Disclosure of Invention

The invention aims to provide a novel staggered corn cleaning device, which realizes the movement of a screen surface in 3 degrees of freedom, namely front and back, up and down, left and right, so that materials generate transverse movement on the screen surface, the dispersion degree of the materials on the screen surface is improved, and meanwhile, the transverse movement directions of adjacent screen sheets are opposite, so that the materials are prevented from being adhered and stacked on the screen surface, and the purposes of improving the cleaning efficiency and the cleaning quality of corn grains are achieved.

The purpose of the invention can be realized by the following scheme: a staggered corn cleaning device is characterized in that a front driving crankshaft and a rear driving crankshaft are respectively and rotatably arranged at the front end and the rear end of a frame, the staggered crankshaft is rotatably arranged at the right end of the frame, and the front driving crankshaft, the staggered crankshaft and the rear driving crankshaft are sequentially connected through bevel gears; the screen frame is provided with round holes at two sides, which are respectively sleeved on the front driving crankshaft and the rear driving crankshaft, the screen sheets are 5 in number, and are sequentially and slidably mounted on the screen frame, the slide way is fixedly mounted below the screen sheets, one side of the connecting rod is rotatably mounted on the slippage crankshaft, the other side of the connecting rod is hinged with the slide block, the slide block is slidably mounted on the slide way, and the driving belt wheel is fixedly mounted at the end part of the slippage crankshaft. The dislocation crankshaft is divided into 5 sections, and the adjacent 2 sections of crank throws have the same height and opposite directions. Each screen sheet is provided with 2 disturbance belts, and the height h range of the disturbance belts is 5-30 mm.

The beneficial effects of the invention are as follows: the front and rear driving crankshafts drive the screen surface to move in the front and rear directions and up and down 2 directions, so that the materials are moved backwards and thrown upwards, the 5 screen pieces are respectively driven to move in the left and right directions by the staggering crankshafts, and the materials on the screen are dispersed along the width direction of the screen surface by matching with a disturbance belt arranged on the screen surface, so that the dispersity of the materials on the screen is improved, the adhesion and accumulation of the materials on the screen are avoided, and the corn grain cleaning machine has the characteristics of simple, reliable and reasonable structure, high corn grain cleaning efficiency, good cleaning quality, suitability for cleaning operation aiming at large feeding amount and high-humidity materials and the like.

Description of part numbers in the figures: in the figure, 1 frame, 2 screen frames, 3 screen surfaces, 4 disturbance belts, 5 front driving crankshafts, 6 rear driving crankshafts, 7 connecting rods, 8 driving belt wheels, 9 bevel gears, 10 staggered crankshafts, 11 slide blocks and 12 slide ways are shown.

Detailed Description

The invention will be further described with reference to the accompanying drawings and examples. A staggered corn cleaning device is characterized in that a front driving crankshaft 5 and a rear driving crankshaft 6 are respectively and rotatably arranged at the front end and the rear end of a frame 1, a staggered crankshaft 10 is rotatably arranged at the right end of the frame 1, and the front driving crankshaft 5, the staggered crankshaft 10 and the rear driving crankshaft 6 are sequentially connected through a bevel gear 9; two sides of the screen frame 2 are provided with round holes which are respectively sleeved on the front driving crankshaft 5 and the

rear driving crankshaft

6, 5 screen pieces 3 are sequentially and slidably arranged on the screen frame 2, a slideway 12 is fixedly arranged below the screen pieces 3, one side of a connecting rod 7 is rotatably arranged on the dislocation crankshaft 10, the other side of the connecting rod is hinged with a sliding block 11, the sliding block 11 is slidably arranged on the slideway 12, and a driving belt wheel 8 is fixedly arranged at the end part of the dislocation crankshaft 10. The dislocation crankshaft 10 is divided into 5 sections, and the adjacent 2 sections have the same crank throw height and opposite directions. Each screen plate 3 is provided with 2 disturbance belts 4, and the height h range of the disturbance belts 4 is 5-30 mm.

When cleaning operation is carried out, external power is transmitted through the driving belt wheel 8 to drive the stagger crankshaft 10 to rotate, the stagger crankshaft drives 5 connecting rods 7 to respectively drive 5 sieve sheets 3 to do reciprocating motion along the width direction of the sieve surface when rotating, and simultaneously the stagger crankshaft 10 drives the front driving crankshaft 5 and the rear driving crankshaft 6 to rotate through two groups of bevel gears 9 so as to drive the sieve surface consisting of the

sieve frames

2 and 5 sieve sheets 3 to do reciprocating motion along the upper and lower directions and the front and rear directions of the device; when materials are fed into the device through the threshing device and the shaking plate (not shown in the figure), the materials fall onto the sieve sheet 3 under the action of gravity, the sieve sheet 3 moves up and down along the device in a reciprocating manner to throw up the materials, and the separation of corn grains and impurities is realized by matching with a fan (not shown in the figure); the reciprocating motion of the sieve sheet 3 along the front and back directions of the device enables the material to be transported backwards to the sieve, and the corn kernels are screened in the process; the screen pieces 3 are matched with the disturbance belt along the staggered movement in the left and right directions of the device, so that the materials are quickly dispersed along the width direction of the screen surface, and the utilization rate and the screening efficiency of the screen surface are improved.

The staggered corn cleaning device designed by the invention has the characteristics of simple, reliable and reasonable structure, high corn grain cleaning efficiency, good cleaning quality, suitability for cleaning operation of large feeding amount and high-humidity materials and the like.
