Abstract
The utility model discloses a device for enhancement of grains threshing efficiency, comprising mainly of a roller, a top lid at the top of the roller and a concave plate screen at the lower section of the roller. A rippling device for loosening crops is provided along the axial direction of the concave plate screen. The rippling device is provided with rippling gears that penetrated into the space between the roller and the concave plate screen. After the setting of the rippling device, the flow of grains that highly rotates within the roller will be loosened. In this way, convenient threshing of grains can be ensured. Moreover, the rippling gears at the separation concave plate area can also enhance flow separation of grains. Therefore, the cases of under-threshing and clamping of grains in the discharged straws can be effectively reduced. The effect of the utility model is especially significant in harvesting wet crops like rice.
Description
Technical field
The utility model relates to a kind of installed threshing separator of combine, relates in particular to a kind of installed threshing separator that is applicable to the various crop results.
Background technology
The operation principle of the sheller unit of combine is: crop does the axial flow motion vertically under the effect of cylinder, notch board and top cover, in this process, seed is come off, the cauline leaf distortion, taken off seed and partial impurities and short cauline leaf and fallen after separating by notch board under the centrifugal action, the axially-movable of crop is that the rotation by the stock guide of top cover and cylinder realizes.
Because the difference of the different and identical crop maturity of crop causes the threshing difficulty or ease of seed different, crop is difficult to the uniformity that the realization seed separates with straw with identical axially-movable speed; The power of engine has been wasted in the excessive threshing of segregative crop; The crop of more difficult threshing after the motion vertically, can not be realized separating fully of seed and stalk in sheller unit, cause threshing not reach entrainment loss only.
The problems referred to above are the ubiquitous technical problems of all combines, and engineers and technicians adopt various technological means to solve always.Conventional means as shown in Figure 7, threshing concave plate sieve 1 comprises sieve side plate 11, bottom screening plate 12 and adjustable plate 13, sieve side plate and drum cover (not shown) are fixed, bottom screening plate 12 1 sides are hinged with sieve side plate 11, opposite side and adjustable plate 13 are hinged, are fixed with suspension rod moving up and down on the adjustable plate 13; During work, the operator moves up and down suspension rod by manipulation device, drives adjustable plate 13 activities, regulates the gap of threshing concave plate sieve 1 and threshing cylinder (not shown); This gap needs the driver to regulate according to the crop different situations when results, to improve the threshing effect, reduces the threshing loss.
Also has a kind of technical scheme that improves threshing efficiency, the applying date is on November 29th, 2002, the patent No. is that 02255589.7 utility model patent " sheller unit of combine " has detailed record, as accompanying drawing 8, shown in the accompanying drawing 9, the sheller unit of combine comprises cylinder 3, be positioned at the top cover 4 of cylinder 3 tops, be positioned at the concave grate of cylinder 3 belows, described top cover 4 inboards are provided with stock guide 41, described stock guide 41 is articulated on the top cover 4, there is the adjusting device 42 that to regulate stock guide guide angle to be connected with described stock guide 41, regulate the angle of stock guide like this by adjusting device, axially-movable speed with regard to the controlled crop, thereby can be according to the difference of crop and the difference of identical crop maturity, the realization seed separates with straw.
Though above-mentioned several technical scheme has all improved threshing efficiency, but when the relatively moister crop of harvesting paddy rice etc., because the discontinuity of crop feeding makes crop break into bulk easily in sheller unit, the seed fringe is wrapped up by stalk, causes threshing not reach entrainment loss only; Prior art never solves this technical barrier.

As a kind of improvement, described rippling device comprises the some broach that are fixedly mounted on vertically on the concave grate.
As a kind of improvement, described rippling device comprises the some broach seats that are fixedly mounted on vertically on the concave grate, and described broach is installed in the broach seat.
As a kind of further improvement, for being threaded, and being provided with broach is locked at locking device on the broach seat between described broach seat and the broach.
As a kind of further improvement, after comprising the threshing concave plate sieve that is positioned at front end and be positioned at the threshing concave plate sieve, described concave grate separates concave grate, and described rippling device is arranged on the threshing concave plate sieve.
As a kind of further improvement, described threshing concave plate sieve comprises and fixing sieve side plate, bottom screening plate and the adjustable plate of drum cover, bottom screening plate one side is hinged with the sieve side plate, and opposite side and adjustable plate are hinged, and described rippling device is arranged on the sieve side plate of fixing with drum cover.
As a kind of further improvement, also be provided with rippling device on the described separation concave grate.
As a kind of further improvement, described separation concave grate comprises fixed screen deck and active sieve plate, and rippling device is arranged on the fixed screen deck.
Owing to adopt technique scheme, a kind of device that improves separation efficiency for threshing comprises cylinder, be positioned at the top cover of cylinder top, be positioned at the concave grate of cylinder below, described concave grate upper edge is axially arranged with the rippling device of loose crop, and described rippling device is provided with the broach that extend into space between cylinder and the concave grate; After rippling device is provided with, material is curried tooth during the high speed rotating threshing in drum chamber disperses, and loose, threshing easily that material becomes are separating currying tooth and also promoting cereal to separate of notch board zone simultaneously, thereby the situation that can reduce effectively that threshing is clean, carry secretly in the Lysimachia sikokiana reduces field loss; The utility model is very obvious to the results effect of moist crops such as paddy rice.
