Abstract
The utility model relates to a stalk shredding stubble cleaner of a suspended and front-installation type. A suspended type cleaner frame is provided with two cutter shafts which forwards incline and inwards and oppositely rotate, the cutter shafts and a horizontal plane form an angle of 70 DEG to 85 DEG, and multilayer moveable cutter blades are arranged on the cutter shafts. Stubble breaking cutters and stubble cleaning cutters are arranged at the lower ends of the cutter shafts, two rows of multilayer fixing cutter blades are arranged on the back plate of the cleaner frame, a nearside divider is arranged in front of both sides of the cleaner frame, and two land wheels are arranged at the back sides of the cutter shafts on the cleaner frame. The utility model has the characteristics of high shredding quality, less power consumption, no pretermission of long stalks, stubble cleaning and wide using range, and is especially suitable for the use of baby tractors which have 12 to 15 horsepower and have the maximum using quantity in China.
Description
The utility model relates to pulverizes straw crop conditioner technical field.
In the past, CN2073653U disclosed a kind of " vertical straw-returning cracker ", was used for the field chopping of maize straw, the preposition suspension type of tractor, and its swivel knife shaft is perpendicular to the ground, and cutting knife horizontally rotates cornstalk is shredded.This kind cutter mill, power consumption is big, and stalk has the omission phenomenon, and high rand and ridge ditch root stubble-cleaning weak effect can not carry out breaking, and result of use is not fully up to expectations.
The purpose of this utility model provides a kind of suspension front positioning type straw cutting-up stubble-cutting machine, and it addresses the above problem by measures such as cutter shaft lean forward, and its cutting quality is good, and stalk does not have the omission phenomenon, and power consumption is low, and can breaking, and is easy to use, effective.
The utility model is achieved in that a kind of suspension front positioning type straw cutting-up stubble-cutting machine, it is characterized in that having the suspension type adjustable housing, by bearing block 2 inwardly cutter shafts that turn forward to changeing are housed on the frame, cutter shaft is horizontal by 70 ° of-85 ° of angles, preferably be 75 ° of-80 ° of angles, cutter shaft is provided with the multilayer knife section, stubble breaking knife and stubble-cleaning cutter are equipped with in the cutter shaft lower end, the horizontal ledger-plate of 2 row's multilayers is housed on the plate after the frame, the place ahead, frame both sides is provided with nearside divider, on frame, the back of cutter shaft is provided with 2 land wheels, and is provided with the cutter shaft actuating unit.
In order to make high rand and the broken stubble-cleaning of ridge ditch undercut effective, above-mentioned 2 land wheels can be located at the dead astern of 2 cutter shafts respectively.
In order to make knife section easy to loading and unloading, knife section can be contained in the groove of flute profile cutterhead, flute profile cutterhead one end is equipped with a blade, and center fixed is on cutter shaft.
Above-mentioned frame upper ledge and nearside divider are " U " font forward, purpose is the stalk of standing not to be pushed over firmly, and convenient moving cutting knife cuts off the stalk of standing, in order to make the convenient work of cutting knife, preferably on the frame upper and lower frames 1 crossbeam is housed respectively, the cutter shaft bearing is contained in the place ahead of crossbeam.
Be preferably in two vertical shaft bearing cap positions, be provided with the oil seal type sealing device, to guarantee the service life of bearing under abominable condition of work.
In order to alleviate complete machine weight as far as possible, blade strength is reasonable, and it is top thin that blade is made, and following is thick, as makes and be in top 2/3 knife section and be thin blade, and being in following 1/3 knife section is thick blade.
For making knife section easy to loading and unloading, the location is used reliable, it can be contained in the groove of grooved cutterhead, and grooved cutterhead one end is adorned a blade, and center fixed is on cutter shaft.
In order to guarantee the breaking effect and the service life of stubble breaking knife, stubble breaking knife is preferably made " Ω " type monoblock type, and to increase its intensity, its cutter length should be longer, underground the stalk stubble is shredded so that be deep into.Half cycle buries because the stubble-cleaning cutter leans forward, and reduces resistance, so can save power.As not needing breaking, can make frame lift and get final product.
Because the utility model cutter shaft turns forward, and the frame upper ledge is " U " font opening forward, thus in the chopping process, the stalk of standing can not pushed over, occur pulverizing less than or pulverize long phenomenon.Blade cutting earlier in cutter shaft upper end makes blade painstaking successively during chopping, so consumption of power is few, and chopping rate height.Because 2 land wheels are in the cutter shaft rear, so during the frame lifting, the cutter shaft angle can change, rearmounted land wheel can play the dark effect of limit, thereby can realize not breaking and two kinds of functions of breaking, and does not have stalk omission phenomenon.This machine is suitable for convenient, and purposes is wide, is particularly suitable for using on the small tractor of the 12-15 horsepower of China's owning amount maximum, will welcome by peasants.
Below in conjunction with embodiment and accompanying drawing in detail the utility model is described in detail, but not as to qualification of the present utility model.
Fig. 1 is its structural representation.
Fig. 2 is a land wheel mounting portion vertical view among Fig. 1.
Fig. 3 is Fig. 1 mid frame lower frame header portion vertical view.
Fig. 4 is a grooved cutter head structure schematic diagram.
Among Fig. 1, the upper and lower frame 5 that has the suspension type adjustable housing 1 of quadric chain and pulley stay cord elevating mechanism is " U " font opening forward, be fixed with crossbeam 3 on it, be fixed with two bearing blocks 4 on the crossbeam 3,2 inwardly are contained on the bearing block 4 cutter shaft 6 that changes, fixing 2 gear-box upper ledges for convenience also can increase by a crossbeam, but should not influence the cutting function of " U " opening; Cutter shaft 6 is provided with row's power sheet 7, the lower end is provided with " Ω " type monoblock type stubble breaking knife 9 and stubble-cleaning cutter 10, cutter shaft 6 is 75 °-80 ° with the horizontal tilt angle, frame 1 is provided with two nearside dividers, back (in cutter shaft 6 dead asterns) is provided with 2 land wheels 11, on the frame 1 back plate the horizontal ledger-plate 12 of two row's multilayers is housed, and is convenient to cut off, 13 is 12-15 horsepower tractor, and 2 cutter shafts 6 are respectively driven by belt by the tractor belt wheel by one group of bevel gear, transverse axis and belt pulley on it.
Among Fig. 4,14 for being welded on the flute profile cutterhead on the cutter shaft 6, and knife section 7 places groove, uses bolt.
