Abstract
The utility model discloses a combined soil working machine, which is mainly composed of a hanging frame, a mountain plate, a land wheel assembly, a gear case, a stubble-cleaning device, a rotary cultivator device, a ridging device, a pressing device and a transmission mechanism. The utility model is characterized in that a bidirectional power take-off spline shaft which is arranged in a gear box is connected with a transmission shaft via a universal shaft coupling joint, a telescopic sleeve and a telescopic shaft, consequently improving durability, and eliminating damaging internal stress generated by angular deviation and axial displacement due to the unbalanced farmland operations of manufacture and installation, and thus workpieces have normal operation. The original transmission with a chain wheel and a chain is replaced by the transmission with a triangular belt wheel and a triangular belt, reducing load, and extending the service life of parts. A plurality of stubble-cleaning knives are evenly arranged on a stubble-cleaning shaft of the utility model, improving work efficiency and quality. The utility model has the advantages of good flexibility, high durability and low cost, and can finish the matched operations of soil working of stubble cleaning, rotary tillage, ridging and press.
Description
Technical field
The utility model belongs to agricultural mechanical field, is specifically related to a kind of combined soil preparing machine.
Background technology
The kind of combined soil preparing machine is a lot, and more advanced have 210 type combined soil preparing machines, finishes the tillage operation of stubble-cleaning, rotary tillage, making ridge, suppression simultaneously by 80 horsepowers of tractor-drawns, and efficient is than higher.But also exist than important disadvantages: (1) unreasonable structure, gear-box unidirectional power output, load concentration is on a power transmission shaft, and torsion is crossed big drive shaft and is easily produced torsional deformation and scrap; (2) transmission is selected inappropriately, and sprocket wheel, chain drive part do not have buffering leeway in transmission, easy generation wear and rupture and scrapping under the heavy load effect of alternation; (3) part can not be eliminated the destruction internal stress that is caused by shape and position deviation, power transmission shaft is taked to be rigidly connected, owing in manufacturing, installation and Working motion, easily produce very big shape, position deviation between the mating parts, produce bursting stress in the inside of counterpart unavoidably, make part gross distortion or fracture influence normal moving commentaries on classics of complete machine; (4) arrangement of stubble-cleaning cutterhead not exclusively adapts to farmland operation, and at location arrangements two row's stubble-cleaning cutterheads of ridge platform, the position of ridge ditch is a neutral gear, and actual ridge distance changes, and also has the crop of flat planting, is to produce residual stubble in operation is advanced.
Summary of the invention
The purpose of this utility model is to provide a kind of improved combined soil preparing machine, has improved durability, whole ground efficient and the quality of driving member, so that be applicable to the farmland tillage operation.
The technical solution adopted in the utility model is: combined soil preparing machine is by hanger bracket, the mountain plate, the ground wheel assembly, gear-box, stubble-clearing device, rotary cultivator attachment, the ridging device, suppression device and transmission mechanism are formed, land wheel is arranged on the mountain front edge of board, on the plate central sill of mountain gear-box is set, on the plate of mountain by the bearings paring shaft, rotary tillage shaft and two-way power take-off, plate rear end, mountain is provided with twin beams, ridging assembly and suppression assembly are set in the overarm of twin beams, transmission mechanism is by two-way power take-off, power transmission shaft and driving member are formed, the gear-box both sides are provided with two-way power take-off, power take-off is connected with telescopic by universal coupling, telescopic shaft is movably arranged in the telescopic, telescopic shaft is connected with power transmission shaft by universal coupling, belt pulley is set on the power transmission shaft is connected with the paring shaft upper belt pulley by the V-belt.
The a plurality of stubble-cleaning cutterheads of equidistant layout on the described paring shaft, stubble-cleaning cutterhead bilateral symmetry is provided with the stubble-cleaning blade.
The utility model combined soil preparing machine advantage is:
(1) improved the durability of driving member.
Unidirectional power output spline gear-box is designed to axis, becomes two-way power output spline, owing to be two-way transmission, the load of part reduces, because parts depreciation, fatigue rupture and load are directly proportional, load has alleviated, and has improved durability.Adopted universal coupling to be connected, eliminated the destruction internal stress that is produced owing to manufacturing, installation, caused angular deviation and the axial displacement of unbalanced farmland operation, parts are run well with telescopic.Adopt V-belt output and V-belt to move in the body bilateral symmetry.Alternation with the very big situation of load under can play cushioning effect, be unlikely part of damage.
(2) whole ground efficient and quality have been improved.
On paring shaft, equidistantly distribute the stubble-cleaning cutterhead, adapt to the tillage operation of any ridge distance and flat planting crop.This novel transmission left-right symmetry, stressed about evenly, can improve gait of march or strengthen the operation width, thereby enhance productivity.
(3) reduce manufacturing cost.
Adopt vee-pulley technology simple, easily processing, price is low, adopts universal joint telescopic and telescopic shaft, and part can be located voluntarily, and is easy for installation, reduced assembly fee usefulness.
(4) safety work.
Running balance during operation, part is reliability and durability, has realized safety work.
