Abstract
The utility model relates to a corn harvester with threshing ability, which comprises the components of an original wheat harvester. The utility model is characterized in that the discharge end of a separating mechanism of the original wheat harvester is connected with an upper sieve through a small tossing board, a lower sieve is fixed below the upper sieve, a rear seed plate and a front seed plate are arranged under the lower sieve, one end of the front seed plate is connected with the upper end of a down wind tunnel opening and fixed on a fan spiral casing, and the front seed plate forms an angle with the level surface; the front seed plate has a ventilating window net, which not only can be used for ventilating, but also can be used for flowing seeds; the rear end of the rear seed plate is fixed on a sieve casing body, and the front end is fixed on the upper part of a fixed drop point plate, to make the seed drop off from the fixed drop point; the fixed drop point plate is fixed on the sieve casing; a wind adjusting plate is connected in the inlet of the down wind tunnel.
Description
Affiliated field: the utility model belongs to a kind of farm machinery, particularly a kind of corn picker with threshing ability.
Background technology: existing combined wheat harvester, can only getting wheat, paddy rice, soybean etc., but machine is really powerless for corn, though Chinese patent once disclosed the patent of multiple corn picker, but not finding can harvesting corn, the grain header that corn can be separated from corn stalk again, or can only harvesting corn, can not getting wheat.
Summary of the invention: the purpose of this utility model is a kind of corn picker with threshing ability of design, it can harvesting corn, again can getting wheat, paddy rice, soybean etc., also corn particle can be separated from corn stalk, it is simple in structure, and use value is expensive low.
The purpose of this utility model is to realize like this, design a kind of corn picker with threshing ability, it comprises the parts of former little wheat harvester, it is characterized in that: the discharge end in former wheat harvester threshing mechanism is connected with top sieve by little shuttle board, below top sieve, be fixed with sieve down, under sieve underneath and be equipped with back seed plate and preceding seed plate, preceding seed plate one end is connected with the upper end at leeward road junction and is fixed on the fan spiral case, preceding seed plate and horizontal plane are angled; On the preceding seed plate vent window net is arranged, both can ventilate, can flow seed again; The rear end of back seed plate is fixed on the screen box body, and its front end is drop point plate top fixedly, and seed is fallen from fixing drop point; Fixedly the drop point plate is fixed on the housing; Inlet at lower air duct is connected with air regulating board.
The rhombus net is arranged on the described top sieve, on the following sieve square hole silk screen is arranged.
Be connected with branch water plate on the described watershed, divide water plate highest point to exceed watershed highest point 60-80mm, optimum value is at 75mm.
The course of work of the present utility model is, it utilizes the ceding of Taiwan of original little wheat harvester, and rice pulling wheel pulls out the into ceding of Taiwan to corn straw and fringe and stirs, and moving knife is cut straw from root, delivers to the plate dental roller by delivery chute, delivers to axial-flow type drum again, i.e. thresher.Straw is smashed by grass outlet and is discharged, and enters cleaning room and cleans from the isolated seed of thresher, broken careless mixture.Adopt twice selection by winnowing in two air channels of the utility model setting and the sieve up and down of special construction, the corn seed that is difficult to clean, broken careless mixture are effectively separated.
The effect of its each parts is as follows:
1, upper air duct: the wind of (being collectively referred to as by vent window and the top thereof on the preceding seed plate), is discharged big impurity the thick selection by winnowing of the mixture that gets off from thresher through sieving up and down, and fine impurities is taken away with the wind; There is the square hole silk screen that the impurity of the thick selection by winnowing of warp of getting off from top sieve is taken away fine impurities with the wind through the thin selection by winnowing of sieve down on the following sieve.
2, be fixed with preceding seed plate and back seed plate below sieving down, preceding seed plate is divided into two former air channel, two air channels Reasonable Orientation; In the middle of the preceding seed plate vent window net is arranged, not only can ventilate but also can flow seed.
3, the back stream seed plate to former grain header raise (putting back to original position when receiving wheat) allow the wind of lower air duct through fixing drop point plate below, under the effect of quantitative wind-force, reach and clean effect more completely.
The utility model has the advantages that: because it is changed a social system on former wheat grain header basis, so cost is low, it can harvesting corn, corn particle is separated from corn stalk, again can getting wheat, paddy rice, soybean etc., the parts that only need dismantle increase when making the wheat grain header get final product, but and a tractor serves several purposes, the use value height, function simple in structure is strong.
Below in conjunction with the embodiment accompanying drawing the utility model is described further:
Description of drawings: Fig. 1 is an embodiment schematic diagram of the present utility model;
Among the figure, 1, separating mechanism; 2, little flitch; 3, top sieve; 4, sieve down; 5, back seed plate; 6, preceding seed plate; 7, fan spiral case; 8, divide the water plate; 9, fixing drop point plate; 10, watershed; 11, lower air duct; 12, air regulating board; 13, upper air duct; 14, the screw feeder of putting out cereal.
Embodiment: separating mechanism 1 discharging opening 2 in former little wheat harvester is connected with top sieve 3 by little shuttle board 2, below top sieve 3, be fixed with sieve 4 down, under sieve 4 underneath and be equipped with back seed plate 5 and preceding seed plate 6, before seed plate 6 angled with horizontal plane, and former air channel be divided into two form upper air duct 13 and lower air duct 11; Preceding seed plate 6 one ends are connected with the upper end at leeward road junction and are fixed on (preceding seed plate does not participate in vibration) on the fan spiral case 7, on the preceding seed plate 6 the vent window net are arranged, and both can ventilate, and can flow seed again; The rear end of back seed plate 5 is fixed on the former screen box body, and its front end is drop point plate 9 tops fixedly, and seed is fallen from fixing drop point plate 9; Fixedly drop point plate 9 is fixed on the housing; Inlet at lower air duct 11 is connected with air regulating board 12, and air regulating board 12 can change the ratio that goes up lower air duct.Reasonably air flow rate proportioning helps cleaning corn seed and impurity.The corn of cleaning is at last discharged from the screw feeder 14 of putting out cereal.Have the rhombus net on the top sieve 3, have the square hole silk screen on the following sieve 4.Be connected with branch water plate 8 on the watershed 10, divide water plate 8 highest points to exceed watershed 10 highest point 60-80mm, optimum value is at 75mm.
