The purpose of summary of the invention the utility model is to provide a kind of straw field pickup reaping machine, and it is without rotary blade, and the harvesting crops stalk is not with soil, and directly the chopping throwing is delivered on the trailer subsequently, and picking and chopping is once accomplished, and is very useful to animal husbandry.
The technical scheme of the utility model is following:
This device is made up of the output of pickup, conveyer, cutting machine and tractor and power thereof, transmission device; 2 wheels are installed on the frame, are welded with draw bar on the frame, this draw bar links to each other with the tractor-drawn ring, and above-mentioned pickup is located at a side of conveyer, and pickup connects the switching-over gearbox of reaping machine through transmission device; Driving lever is arranged on the conveyer, and driving lever connects the switching-over gearbox of this reaping machine through reverse drive gear; Conveyer connects cutting machine, and this machine has shredding mechanism and discharging opening, and this machine main shaft is through transmission device interlock power gearbox, and the switching-over gearbox of above-mentioned reaping machine connects the rear output shaft of tractor through actuating unit.
Two driving levers are arranged on the above-mentioned conveyer, and two driving levers connect the switching-over gearbox of this reaping machine respectively through switching-over travelling gear sprocket wheel.
The advantage of the utility model is: 1, collects stalk on the ground, is not with soil, reduce the disease of domestic animals with pickup, and very favourable to animal husbandry.2, this device is by tractor-drawn, and operation power is provided, and pickup, conveyer, cutting machine combine, make to pick up, carry, cut up with a hay cutter to cut once and accomplish, and throw deliver to trailer on, efficient is high.3, this device is reasonable in design, and compact conformation is reliable, and rubbing the broken hand hay cutter section that changes is the machinery that practical results are spread stalk.
Embodiment is described further the utility model below in conjunction with accompanying drawing.
Among Fig. 1-2: 1, tractor, 2, universal drive shaft, 3, power transmission-gear box, 4, universal drive shaft,
5, cutting machine main shaft, 6, wheel, 7, belt pulley 8, sprocket wheel, 9, sprocket wheel, 10, sprocket wheel, 11, chain, 12, bevel pinion; 13, bevel gear wheel, 14 bevel pinions, 15, bevel gear wheel, 16, driving lever 17, conveyer, 18, pick up pawl; 19, pickup, 20, belt pulley, 21, sprocket wheel, 22, chain; 23, cutting machine, 24, draw bar 25, frame, 26, belt, 27, the switching-over gearbox.
Can see the structure of this device by Fig. 1,2 by pickup (19), conveyer (17), cutting machine (23) and tractor (1); The tractor dynamic power output device is that rear output shaft passes through rotary power universal drive shaft (2), power transmission-gear box (3), reaches universal drive shaft (4), reaches on the main shaft (5) of cutting machine (23); Frame (25) goes up installs 2 wheels (6), is welded with draw bar (24) on the frame (25), and this draw bar (24) links to each other with the tractor-drawn ring; Above-mentioned pickup (19) is located at a side of conveyer, and pickup is that the pawl rotation is picked up in belt pulley 20 drives, and belt pulley (20) connects the switching-over gearbox (27) of reaping machine through transmission device; Two driving levers (16) are arranged on the conveyer, driving lever through switching-over drive bevel gear 12,13 and 14,15 and sprocket wheel (10) connect the switching-over gearbox (27) of this reaping machine; Conveyer connects cutting machine, and this machine has shredding mechanism and discharging opening 28, and above-mentioned reaping machine switching-over gearbox (27) is through main shaft (5) the interlock power gearbox (3) of drive sprocket (8), (9) cutting machine (23).
Operation principle is following: tractor (1) rear output shaft passes through rotary power universal drive shaft (2), power transmission-gear box (3), reaches universal drive shaft (4); Reach on the main shaft (5) of cutting machine (23); Main shaft (5) rotation is cut up with a hay cutter stalk and is cut and through inner transmission system rotary power is reached again on the sprocket wheel (8); Sprocket wheel (8) rotating tee is crossed chain (22) and reached on the sprocket wheel (9), and is as shown in Figure 2, and switching-over goes on sprocket wheel (21) and the belt pulley (7) through switching-over gearbox (27) in sprocket wheel (9) rotation.Sprocket wheel (21) and belt pulley (7) are on same axis.Show that like Fig. 1 belt pulley (7) goes on the belt pulley (20) through belt (26), belt pulley (20) rotation drives to pick up that pawl (18) is picked up and stalk hugged and delivers on the conveyer (17).Sprocket wheel (21) rotates and goes on the sprocket wheel (10) through chain (11); Sprocket wheel (10) rotates on same axis with bevel pinion (12), (14); Bevel pinion (12), (14) and bevel gear wheel (13), (15) engagement; The speed change that commutates rotation, bevel gear wheel (13), (15) drive 2 driving levers (16) motion respectively.Driving lever (16) is done link motion, and stalk is crowded in the cutting machine (23), and cutting machine (23) is delivered to discharging opening with stalks cutting and throwing, accomplishes a complete set of function.
