Abstract
The utility model relates to a combined corn harvester which is used for picking corn ears, collecting corn ears, crushing stalks, returning the stalks to field and plowing stubbles. The utility model is composed of a power input assembly, an ear picking device, a stalk crushing and stubble plowing device, etc. The utility model changes the belt transmission mode of the prior art into a transmission mode which uses a speed changing box, so the height and the level inclination angle of a picking roll can be regulated in a large range. When installed on a tractor, the utility model can walk on a highway; the utility model can be matched with a four-wheel tractor with 15 horsepower to 20 horsepower.
Description
The utility model relates to agricultural mechanical field, particularly a kind of small-sized corn combine.
At present, China's vast rural area harvesting corn majority still adopts manual harvesting, and labour intensity is big, and efficient is low.Indivedual local employing reaping corn machineries, straw is pulverized, stubble cleaner but mostly be, and minority has the function of plucking fringe, collection, crushed straw, again can not stubble-cleaning.None example can once be finished full operation operation such as corn picker, spike collecting, stalk crushing and returning, stubble-cleaning according to investigations.Because of not promoting, must move harvesting machinery in the ground to and could use after the installation during each operation.On its transmission system, again take belt or gearbox drive mode more, mechanism's complexity, volume is bigger, can not lifting, can not adjust the inclination angle, make difficulty, the frequency height is installed, required mating power is also bigger.
The purpose of this utility model provides a kind of collection corn picker, spike collecting, and stalk crushing and returning, four kinds of functions of stubble-cleaning are in the small-sized corn combine of one.Because of the gearbox of this machine can promote, so also can on highway, travel even be installed on the tractor.And this machine is simple in structure, and the gearbox lifting is adjustable and left and right horizontal face inclination angle is movable, and mating power is little, is the small-sized corn combine that makes things convenient for the rural area to use.
The utility model is achieved in that imports assembly with power and engine flywheel is fixedly connected, through chain drive power is sent in the operating mechanism, operating mechanism by gearbox with power distribution to plucking working positions such as fringe, fruit ear transmission collection, stalk crushing and returning, stubble-cleaning, make each working position coordination, and rationally mate with the tractor speed of travel, realize disposable harvesting operation.
The utility model has the advantages that: 1. multiple functional, can disposablely finish that corn picker, spike collecting, straw are pulverized, the full operation operation of stubble-cleaning, the efficient height, save time, laborsaving; 2. simple in structure, easy to install; 3. operating mechanism's angle and adjustable height are suitable for travelling on the harvesting of different growing way corns and the face road surface; 4. required mating power scope is wide, and adaptability is strong.The utility model is described in further detail below in conjunction with accompanying drawing;
Fig. 1 is the utility model operating mechanism schematic diagram;
Fig. 2 is the utility model power input assembly structure schematic diagram.
As shown in Figure 1: power input assembly 2 is fixed on the engine flywheel 1, and rotates with speed with flywheel 1, by chain 18 power is sent to sprocket wheel 7 on the gearbox 6, realizes transmission of power.Gearbox 6 links by bracing frame 4 and tractor, and gearbox 6 can move up and down through pulley 3 along the slideway of bracing frame 4 under the drive of tractor hydraulic elevator 19, realizes that the height of operating mechanism is regulated.Gearbox 6 is regulated by leading screw 5 with the inclination angle of horizontal plane, and during rotating threaded shaft 5, gearbox 6 increases with the horizontal plane inclination angle to the right, and when anticlockwise, the inclination angle reduces.Pluck roller 9 for two and place gearbox 6 the place aheads.Pluck and be equipped with the opposite helical form of direction of rotation on the roller 9 and pluck fringe pawl 10, pluck and do rotation relatively under the gear driven of roller 9 in gearbox 6, realize plucking fringe; Corn stalk tilts when preventing to gather in the crops, and plucks roller 9 front ends and is equipped with and draws device 12 in, draws device 12 usefulness bolted on frame 11.Dialing-grain unit 8 is installed on the frame 11.Dialing-grain unit 8 enters in the slit of plucking roller 9 corn stalk through gearbox 6 middle gear driven rotary smoothly.Corncob under the results falls into transport tube 13.Sprocket wheel 14 is installed on the transport tube 13,,, corncob is collected in the container, realize plucking fringe by being installed in the conveyer belt of transport tube inside in sprocket wheel 7 rotation under chain 15 drives.
After corn stalk enters the slit of plucking roller 9, tangentially move down along plucking roller 9 circumference with higher linear speed, the straw reducing mechanism 16 that is placed in the high speed rotating of bracing frame 4 belows is pulverized and is let go, realizes returning crop stocks to the field.Stubble-cleaning cutterhead 17 and the 16 coaxial rotations of straw reducing mechanism screw in the root stubble degree of depth in the soil, with the corn stubble fragmentation, realize stubble-cleaning.
Below in conjunction with Fig. 2 power input assembly of the present utility model is further described.The utility model institute mating power is a 15-20 horsepower four-wheel tractor.Belt pulley 20 usefulness bolts 27 are fixed on the tractor engine flywheel 1, rotate with speed with flywheel 1, drive the tractor walking.The profile of tooth of belt pulley 20 right side system teeth and half a coupler 21 left sides meshes and rotates with speed.Half a coupler 21 right-hand members are made sprocket wheel, and whole sky is enclosed within on the power transmission shaft 24, and can slide vertically.When it rotates, power is input in the gearbox by chain 18.Power transmission shaft 24 adopts thread connection on bent axle 28.Clutch adopts castle wheel 22 and 23, and castle wheel 22,23 contact-making surfaces are spiral camber.22 of castle wheels move axially, and 23 of castle wheels rotate.Castle wheel 22,23 is placed on the power transmission shaft 24, by control crank castle wheel 23 is turned clockwise, and the two-wheeled gap is strengthened, and half a coupler 21 moves right under spring 26 effects, realizes that transmission separates; Be rotated counterclockwise castle wheel 23, under the spiral camber effect, promote half a coupler 21 by castle wheel 22 and be moved to the left, half a coupler 21 and the engagement of belt pulley 20 tooth portions are realized driving coupling.Can regulate the tooth portion back lash of half a coupler 21 and belt pulley 20 by nut 25, and make parts on shaft realize axial location.
