Abstract

The utility model discloses a thresher for spike seed, which comprises a threshing chamber and a fan cleaning and selecting system. A motor shaft, a roller and a fan are driven by a strap, and spike heads of seed are fed in the threshing chamber through a feeding groove plate and are threshed by the roller. The utility model is characterized in that the roller is arranged in a saw tooth concave plate and a sieve which can be opened or a concave plate for forming a sealing threshing chamber; bow teeth which are arrayed in an N shape are fixed on the outer wall of the roller; a sieve type concave plate is communicated with a front lower slide plate; the side surface of the sieve type concave plate is a seed leaking plate; a blowing fan which can separate sundries and seed is arranged on a machine frame; a funnel is connected to the lower slide plate. The utility model has the advantages of strong threshing, better awn peeling effect, better cleaning and selecting effect, no mixed seed, etc. Besides, the utility model can accurately reflect experimental results of seed breeding.

Description

Fringe strain seed thresher

Technical field:

The utility model relates to a kind of fringe strain seed thresher, is specially adapted to agri-scientific research, to crops crossbreeding test, and the threshing and cleaning facility that the multiple shape of super original seed purification is used.

Background technology:

Last century the eighties; the single-strain seed thresher of introducing from world-renowned Austrian Ao Yuete company by the Chinese Academy of Agricultural Sciences; it comprises the threshing cleaning unit of motor, frame, sealing; with seed box etc.; its feeding mouth is at the top; in the threshing chamber of sealing, board-like threshing roller, ripple type notch board and the able to turn on or off board-like notch board of arc are housed, slide plate and seed-leaking port are installed below the threshing chamber, take out the side that assorted blower fan is contained in casing.The threshing roller is board-like, flexible material is equipped with in the plate outer end, corrugated notch board is housed in the threshing chamber, when using, this machine must cut the fringe head from straw, the feeding program is many, time-consuming, this machine can perfectly be finished the threshing and cleaning task, and do not mix wherein shortcoming be because of the threshing original paper be plate, the threshing ability, cut fringe again,, per hour can only take off more than 100 individual plant so efficient is low, cleaning loss is more, this machine the eighties in last century is introduced by the Chinese Academy of Agricultural Sciences, 1700 dollars every, costs an arm and a leg.

The invention task:

Task of the present utility model be propose a kind of powerful threshing to be arranged, to take off the awns ability strong and minimum to the seed damage, cleans effectively, seed does not mix; percentage of damage is low, and total losses is few, high efficiency; can accurately reflect the seed breeding result of the test, and the low fringe strain seed thresher of cost.Task of the present utility model is finished like this; fringe strain seed thresher; it comprises threshing chamber and fan cleaning and sorting system; between motor shaft and cylinder, the blower fan by belt transmission; seed fringe head feeds threshing chamber through the feeding frid; by drum threshing; it is characterized in that: cylinder is contained in the sawtooth notch board and opens to form the sealing threshing chamber in the sieve that can open or the notch board; cylinder outer wall is fixed with the bow tooth that N shape is arranged; cylinder greate communicates with preceding lower skateboard; its side is to leak kind of a plate, and the blowing fan that foreign material and seed are separated is installed on frame, is connected with funnel on the lower skateboard.The shape of leaking kind of plate is the plate face that is interrupted, and seed flows into funnel along discontinuities and advances seed box.The horizontal sextant angle that leaks kind of plate and lower skateboard is 53 °, and leaking kind of plate is slype with the sliding closure plate formed shape in back.The utlity model has following effect: it is zero that fringe strain seed thresher has the residual quantity of crop kernel in machine; in the threshing and cleaning operation; variety rotation is frequent; but all keep kind not mix; the result of the test that can accurately reflect seed breeding; under wheat seed water content 15～23% complete ripeness conditions, its performance indications are as follows:
