Abstract

The utility model discloses a self-walking type harvesting machine of maize, which is hung against the front of the wheat combine harvester. The ear picked by the ear picker which is peeled through pulling the stem, but with no threshing, and is transferred directly to the granary on the truck by three elevating devices of the blade type first time elevator arranged at one side of the snapping roll; the auger is perpendicular to the first time elevator, and the blade type second time elevator is at the side of the harvester. The utility model adapts to the national condition that when harvesting the maize at the planting area of north of the country where planting wheat and maize two times, the moisture content of the ear is so high that the threshing can not be done instantly, and increases the utilization ratio of the wheat combined harvester. In addition, a straw cutter is arranged at the lower part of the harvesting machine, and the straw returning can be done when harvesting the maize.

Description

Self-walking type harvesting machine of maize

The utility model relates to a kind of agricultural harvesting machine, a kind of more precisely maize harvesting machine of being affiliated on the anterior gap bridge of combined wheat harvester.

The northern China the greater part is wheat and two batches of growing areas of corn, be the wheat of beginning sowing in good time, promptly to not gather in the crops in the full maturity as yet at corn mostly, the corn ear of accepting contains moisture more (about 38%), and threshing immediately must be through further drying the ability threshing, otherwise lose bigger, moreover the Ministry of Agriculture advocates the corn stalk mincing and returning to the field after will gathering in the crops, with fertile soil fertility.What China made at present reaches from the combined wheat harvester of U.S.'s introduction; but though harvesting corn after the ceding of Taiwan before more changing planes; promptly corn stalk is dialled in snapping bar by the rice-pulling chain on the maize harvesting machine; fruit ear is taken together with part leaf stalk; after being sent to separating mechanism in the grain header chamber and carrying out threshing and blow off with elevator; by the secondary elevator iblet is thrown in the into accompanying automobile goods bucket again; but this results program can not be used in China; thereby the combined wheat harvester availability is reduced greatly, and in addition, the corn stalk of plucking behind the fringe is still long in the ground; also to manually remove; both waste the labour, easily missed the farming season again, also do not reached the requirement of returning crop stocks to the field.

The purpose of this utility model be the design a kind of maize harvesting machine that tallies with the national condition, it is taken corn ear after, refuse threshing, directly send fruit ear to airborne silo by hoisting equipment, to avoid the threshing loss, simultaneously with the instant mincing and returning to the field of its straw, with fertile soil fertility.

Accompanying drawing has provided specific embodiment of the utility model.

Fig. 1 is the utility model outside drawing;

Fig. 2 is its plan structure transmission system schematic diagram of holding concurrently;

Fig. 3 is snapping bar assembly structure and a transmission system schematic diagram thereof in its harvesting apparatus;

Fig. 4 is that the A of Fig. 3 is to figure.

This maize harvesting machine is by hanging on the anterior gap bridge (5) of combined wheat harvester (7), and rise and fall with oil cylinder (6) control, this machine comprises harvest corn device (1), the fruit cluster delivering device, transmission system and silo (8), the improvement main points are, said fruit cluster delivering device comprises the scraper-type elevator (12) of two fruit cluster deliverings that the harvest corn device can be taken to screw feeder, fruit ear can be put together the screw feeder (17) of shifting the secondary elevator onto and the scraper-type secondary elevator (3) that fruit cluster delivering can be arrived silo (8), wherein screw feeder (17) is contained in the downstream end of an elevator (12), be connected with two elevators and vertical with its traffic direction, secondary elevator (3) is contained in the pusher side of maize harvesting machine, its lower end is connected with screw feeder (17) downstream end, and can in vertical plane, rotate an angle around being located near the sprocket shaft of linking point, its upper end is then by hanging over the upper edge of silo (8), in addition, in the bottom of maize harvesting machine one group of straw chopper (2) is housed also.During work, by provide power walking and results by the combined wheat harvester of hanging, milpa is led device (9) and enters harvesting apparatus along holding up, by the rice-pulling chain that has bat (10) milpa is dragged on up and down between the snapping bar (11), plucking fringe part (33) by it earlier takes fruit ear, after drawing stem portion (34) that the fruit ear crust is left behind together with cane, drop into an elevator (12) again, and be sent to silo (8) through screw feeder (17) and secondary elevator (3), meanwhile, corn stalk is by chopper (2) mincing and returning to the field.

For raising is plucked fringe effect, weight reduction, makes easily and reduced cost, the most handy steel pipe of upper and lower snapping bar (11) in the harvest corn device (1) is made, and is used to the also available reinforcing bar weldering of the helix system of plucking fringe and drawing stem on its periphery.

Pour into effortlessly rapidly in the automobile goods bucket for making the corn ear of filling silo (8), silo (8) can be designed to self-tipping type, for example use the tipping bucket type silo of oil cylinder (27) driving that is contained in the silo bottom, for making secondary elevator (3) not influence the silo tipping bucket by hanging over the silo edge, can adorn an oil cylinder (4) in the bottom of secondary elevator (3), throw off silo around the rotating shaft of its underpart angle of steeving in order to drive the secondary elevator.

The preferred plan of this machine transmission system is seen Fig. 2 and Fig. 3, its power source is from the sprocket wheel (28) on the power output jackshaft of combined wheat harvester (7), it is with the chain drive axle (26) of passing a bridge, be divided into two the tunnel then, lead up to sprocket wheel (25), gap bridge jackshaft (23), straw chopper gearbox (22) and sprocket wheel (21) drive straw chopper (2), it is rotated counterclockwise, another road is by sprocket wheel (24), reverse box (19) and sprocket wheel (20) (16) drive harvesting apparatus transmission system and secondary elevator (3), and drive screw feeder (17) by sprocket wheel.Wherein the harvesting apparatus transmission system is by sprocket wheel (13) snapping bar sprocket wheel (31) in ear-picking gear box (15) drive, single rice-pulling chain sprocket wheel (14) and double seedling chain sprocket wheel (29), and sprocket wheel (31), (14) and (29) can a shared chain drive, and with sprocket wheel (32) be regulating wheel (certainly, above-mentioned three chain gear transmission also can be used gear drive instead, here using sprocket wheel is to be simplified structure), drive snapping bar axle (30) backward rotation down and go up snapping bar axle (31) by gear mesh (35), snapping bar is to win corn ear and to draw stem to the form of rolling up and down.

The utility model is simple and compact for structure, in light weight, low cost of manufacture, use dexterous reliable, particularly be fit to China's national situation, be used for wheat and corn regrowth hair growing area, can enlarge the function of combined wheat harvester, improve its availability, union is held up and is led, plucks fringe, elevator, storage, automatic unloading and returns crop stocks to the field in one, the automaticity height, can effectively improve the Tendency of Agricultural Machinery in China level, in addition, its supporting adaptability is also very strong, for example with 1065, type combined wheat harvester such as Beijing 25, east wind-5 and E514 all can be supporting, and the popularization future is arranged very much.
