Compression straw collecting transport vehicle
The mechanization that the present invention relates to agricultural crop straw is collected and transportation, is specifically related to compression straw collecting transport vehicle.
Agricultural recycling economy is a kind of new economic development theory, also is the new growth engines in rural area.On the developing agricultural recycling economy, stalk has become indispensable valuable source.China has 700,000,000 tons of various straws every year approximately, at aspect stalks such as straw burning generating, production construction material, straw silage, stalk marsh gas the field that utilizes is widely arranged.Stalk is made the rural economy flourish promoting agricultural development, and more and more important effect is just being brought into play in the aspect of increasing farmers' income.
But the collection problem of stalk has but become a bottleneck of above these application.
At present external straw collecting uses large-scale straw collecting binder more, and this type of machinery is applicable to the land for growing field crops operation, and expensive.Present stage national conditions from China, the straw collecting binder mainly is divided into two kinds in circle bundle and square bundle machine, machine for forming cylindrical bale since intermittence bundling, pick up during bundling and stop, productivity ratio is not high, the density of tying up is lower, occurs obstruction or disconnected rope phenomenon in the bundling operation easily, and its advantage is that its structure is wanted simply relatively, volume is also less, thereby cost is lower, and price is more cheap, and operating maintenance is simple; The bale density that side's bundle machine is beaten is bigger than machine for forming cylindrical bale, transportation and storage are comparatively convenient, can work continuously, efficient is higher, but its complex structure, the manufacturing cost height, price is also high, and also needs the cooperation of other haulage vehicle during farm work, needs manually loading and unloading, its efficient does not still reach the agricultural operation requirement, and density does not reach the specification requirement of straw electric generation plant yet.The collection of most regional stalks at present can only be adopted manual work, and peasant's enthusiasm is not high, and stalk still adopts on-site incineration or abandons in rivers and canals, has wasted this valuable resource, has also polluted environment simultaneously.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of compression straw collecting transport vehicle, and simple in structure, compactness is suitable for, operating efficiency is high.
The present invention is achieved through the following technical solutions:
Compression straw collecting transport vehicle comprises transport vehicle, and the gathering machine that is connected with transport vehicle, described gathering machine comprise cabinet, are arranged at the compression set in the cabinet, be arranged at the gathering unit of cabinet front end, and the stalk after will collecting are sent into the conveyer belt of cabinet;
Described compression set comprises compacting oil cylinder, squeeze board, and described compacting oil cylinder promotes squeeze board by shrinking connecting-rod and moves, and the stalk in the cabinet is compressed;
Described gathering unit comprises Grass pickup attachment, also comprises being positioned at Grass pickup attachment top, shifting stalk onto on the conveyer belt helix transporting device.
The further improvement project of the present invention is, the two ends of described shrinking connecting-rod are connected to cabinet end plate and described squeeze board, and the compacting oil cylinder is parallel to squeeze board, and its two ends are connected with the pin of shrinking connecting-rod up and down respectively.
Be provided with sensor in cabinet, cabinet is provided with back pullout (BPO).
The further improvement project of the present invention is, the compression set top is provided with cover plate, and described cover plate has two formations at least, and wherein one is connected with limit, squeeze board upper end, and cooperates with the cabinet side board activity.When compression set is worked, can prevent that stalk from falling in the compression set.
The further improvement project of the present invention is, described Grass pickup attachment comprises toothed rotor, and described toothed rotor is provided with the case I, and described helix transporting device comprises screw rod, and described screw rod is provided with the case II.Described screw rod is the bar (being commonly called as auger) that is provided with helical blade.
The further improvement project of the present invention is that the front side edge of case I and the periphery of toothed rotor are matched in clearance, which is provided with the notch that passes through of tooth.The effect of the set notch of front side edge of case I is that the stalk on the cylinder tooth is pushed away gear hobbing.The case II covers in described screw rod, and back side edge is connected in the case I, and extend downwards the front side, covers in toothed rotor the place ahead, its limit portion perk forwards.
The further improvement project of the present invention is, screw rod is respectively equipped with connecting axle in the cylinder in the Grass pickup attachment and the helix transporting device, and flexibly connects by the set cantilever of connecting axle and cabinet; Described cantilever is movably connected on cabinet, and is provided with the pull-up oil cylinder.Be respectively equipped with drive on the described connecting axle, described drive is connected transmission by the drive on the set power set output shaft of belt and gathering machine.The output shaft of described power set is movably connected on cabinet.
The present invention compared with prior art has following obvious advantage:
One, the gathering machine among the present invention is equipped with the power set of collecting stalk, compression stalk and stalk being released, be beneficial to traction locomotive (in the use, generally gathering machine is installed and connected in hand tractor) with the separating of compression straw collector, and can alleviate power requirement to traction locomotive.
Two, the present invention collects stalk by the Grass pickup attachment that is arranged on before the cabinet, by conveyer belt stalk is delivered in the cabinet simultaneously, when stalk is stacked into to a certain degree, will touch the pressure sensor in the cabinet, this moment, compaction apparatus was namely started working, stalk squeezed backward push away, to increase the space that stalk continues to enter, after straw collecting case receipts completely arrive certain degree of packing, pressure sensor sends signal, can stop straw collecting work, to the stalk bundling in the compression box or directly be transported to the appointed place and stack.From the above-mentioned course of work as can be known, the present invention is high efficiency (compacting while collecting) not only, and simple in structure, low cost of manufacture.
Three, hydraulic system is made up of the connection cantilever pull-up oil cylinder control section of overflow valve, unidirectional constant displacement pump, accumulator, compacting oil cylinder control section, gathering unit, and overflow valve can prevent system overload, and accumulator can guarantee that system works is steady.Wherein the connection cantilever pull-up oil cylinder control section of gathering unit is made up of manual reverse of direction choke valve, hydraulic control one-way valve, one-way throttle valve, can reduce the Grass pickup attachment pull-up and impulsive force when putting down, and guarantees stable working.
