Background technology
Agricultural straw resource has multifunctionality, can realize stover and appreciate, can be used as fuel, feed, fertilizer, biological base, the raw material of industry etc.But because the harvest season property of stalk is comparatively strong, affect by factors such as lacks of labor, stalk on-site incineration or huddle often leaves about by peasant.Crop straw burning produces toxic gas and contaminated air, constitutes a threat to, there is disaster hidden-trouble, spoiled soil structure, cause farm land quality to decline to civil aviaton, railway, highway traffic safety.Huddle to leave about and affect environmental profile, stalk rots and brings environmental pollution.Just mechanization means must be adopted to realize straw collecting, current domestic main employing semi-mechanization hydraulic pressure beats large square bale equipment, mainly comprise horizontal, vertical hydraulic binder etc., but the major defect of these equipment mainly relies on manual work, need high strength muscle power and high labor cost, the density of bale is high but air permeability is poor in addition, and bale easily goes mouldy, have that disposable input is higher, equipment operating and the high defect of maintenance requirement, to be only suitable for northeastward, Xinjiang Deng great plot operation.So need to develop stalk cutting bundling machine, adopt mechanization means, operation is reclaimed in the mechanization realizing stalk, guarantees that stalk large-scale comprehensive utilizes.
Summary of the invention
The purpose of this utility model is to provide a kind of self-propelled type straw sheaf-binding reaping machine, solves the defect that existing straw harvesting technology exists, realizes stalk mechanized harvest bundling, and than beating the simple small investment of large square bale equipment, towed to beat little square bale mechanical efficiency high than small-sized.
The purpose of this utility model realizes as follows: this self-propelled type straw sheaf-binding reaping machine, comprise self-propelled body, body front end arranges dialing-grain unit, after dialing-grain unit, cutting knife is set, feeding drum is had after cutting knife, the rear outlet of feeding drum connects conveyer belt, the end on of conveyer belt is in being in the feed bin on body, the side of feed bin is the compression bin communicated with feed bin, the poking device being used for stalk being toggled it to compression bin is set on feed bin top, compression bin front portion arranges piston, toggle is connected with between piston and power wheel, compression bin arranges tying device, in compression bin, upper rear end arranges material height detection device, material height detection device associates with the clutch of tying device.During use, self-propelled body drives complete machine to advance, dialing-grain unit rotates and stalk is allocated to cutting knife, by cutting knife by straw cutting, cut-off stalk delivers to conveyer belt by feeding drum, stalk by tape transport to feed bin, stalk in feed bin pushes compression bin by poking device, push the stalk in compression bin to rear end by piston and compress, when stalk reaches certain thickness, touch material height detection device, material height detection device makes the clutch of tying device close, tying device carries out bundling operation, stalk after bundling falls from compression bin rear end, complete a bundling job, complete machine continuous firing, completes straw harvesting, bundling operation.
Poking device is made up of support, wiper arm, connecting axle, swing arm, and there is pusher dog the wiper arm front end of L-type, and rear end and the pedestal upper end of wiper arm are hinged, and swing arm is connected with rotary power, and the front end fixed connection shaft of swing arm, the connecting axle other end is inserted in the axis hole in swing arm.Wiper arm is under the drive of swing arm, and front end pusher dog protracts, fall, dial afterwards, lift and protract, and repetitive operation completes material toggling operation.
Material height detection device is supported on floatable wheel shaft on compression bin two side, and on wheel shaft, fixed test wheel, wheel shaft has the poke rod connecting tying device clutch.After in compression bin, stalk is piled higher and higher, stalk upwardly detects wheel, and detect the wheel belt axis of a movable block and rise, wheel shaft drives poke rod, and poke rod makes tying device clutch close, and tying device work, completes a bundling action.
The utility model and semi-mechanization hydraulic pressure are beaten compared with large square bale equipment, and mechanization degree is high, disposable less investment, equipment operating and maintenance requirement low; Compared with trail-type binder in the past, do not need supporting other power car traction separately, effectively improve operating efficiency.Not only can realize the bundling operation of rice and wheat stalk, harvestry bundling operation can also be carried out to corn, the contour strain crops straw of reed.Can automatic picking stalk, weeds, self-feeding, compression, bundle rope, go out bag, whole process entire roboticized work, easy to operate, efficiency is high.
Embodiment
With reference to Fig. 1, there is a self-propelled body 11, body 11 front end arranges dialing-grain unit 1, dialing-grain unit 1 arranges cutting knife 2 below, cutting knife 2 has feeding drum 3 below, the rear outlet of feeding drum 3 connects conveyer belt 4, the end on of conveyer belt 4 is in the feed bin 6 be on body 11, the side of feed bin 6 is the compression bins communicated with feed bin 6, the poking device 7 being used for stalk being toggled it to compression bin is set on feed bin 6 top, compression bin front portion arranges piston 5, toggle 9 is connected with between piston 5 and power wheel, compression bin is arranged tying device 10, in compression bin, upper rear end arranges material height detection device 8, material height detection device 8 associates with the clutch of tying device 10.Poking device 7 is made up of support, wiper arm, connecting axle, swing arm, and there is pusher dog the wiper arm front end of L-type, and rear end and the pedestal upper end of wiper arm are hinged, and swing arm is connected with rotary power, and the front end fixed connection shaft of swing arm, the connecting axle other end is inserted in the axis hole in swing arm.Material height detection device 8 is supported on floatable wheel shaft on compression bin two side, and on wheel shaft, fixed test wheel, wheel shaft has the poke rod connecting tying device 10 clutch.
