Abstract

The utility model provides a green manure rake for paddy field, having special efficacy. The utility model mainly improves the structure of rake teeth of a rotary rake of a working member. The rotary rake acts on the components of a tooth plate by the method that driving force is penetrated through a partition plate; the tooth plates which are entirely welded on a rake shaft are uniformly distributed on a circumference and are positioned symmetrically along the tooth direction; the tooth plates are orthogonally fixed on the same cross section; tooth direction angles are constant, and tooth plates are raised. The utility model has the advantages of simple structure, flexible operation, compact volume, good slurry rising effect and level paddy field covering areas. The utility model can bury 95% of kibbling grass and stalks into the earth and is particularly favorable for the technical popularization of sprout throwing of paddy rice. The utility model can also provides serial products according to users' requirements.

Description

Paddy-field grass-burying drives rake

The utility model relates to a kind of agricultural operation machinery, and particularly the serial paddy-field grass-burying with tractor drives rake, and the operation that is suitable for returning crop stocks to the field, machine are received the wheatland operation, for planting the use of laying foundation of (throwing) seedling.

According to the knowledge of the applicant: along with the large tracts of land of combine is promoted the use of, a large amount of wheat straw bars has a strong impact on the whole ground quality and the paddy rice of paddy field and plants (throwing) seedling quality, simultaneously most of wheat straws are burned serious environment pollution, influence air traffic, and cause the wasting of resources of fertilizer.And leather driving finishing rake is buried in existing paddy field, because fault of construction, not enough as tooth depth causes and buries not enough, the slurry weak effect of grassiness degree, has influenced and has buried careless also field and rice transplanting quality.

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, designs and manufactures a kind of compact conformation, effective paddy-field grass-burying drives rake.

The purpose of this utility model is that the architecture advances by workpiece realizes: promptly this driving rake comprises from coupling components, power transmission member, workpiece and adjustment component and forming, workpiece rolls rake and is connected as a single entity, receives connecting plate by rotating shaft again and constitute by stay pipe and gear outer case by connector, drive power by spacer function on tooth plate, the tooth plate of integral solder on the rake axle is provided with in the circumference equal intervals, the teeth directional symmetry, tooth plate is mutually orthogonal fixing in same cross section, the tooth angle beta is constant, and the gear piece of increasing is welded on the tooth plate.

Described tooth plate is 30 ° of five equilibrium settings on circumference, the tooth angle beta is with at 100 °--and be advisable between 120 °, gear piece is increased 10--15mm.

Owing to adopt abovementioned technology, make the utlity model has simple in structure, use flexibly, the field table is smooth behind the whole ground, it is effective to play slurry, 95% broken grass and cane can be imbedded in the soil effectively, is particularly conducive to the popularization of rice seedling throwing technology.

Describe in detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model rake axle construction and transmission schematic diagram.

Fig. 2 is tooth plate spare 9 gear pieces 10 angle beta schematic diagrames among Fig. 1.

Fig. 3 is that gear piece 10 is increased the h schematic diagram among Fig. 1, Fig. 2.

Fig. 4 is that schematic diagram is arranged in tooth plate spare 9 cross sections.

Fig. 5 is the position view of tooth plate spare 9 on circumference.

With reference to Fig. 1-Fig. 5, through repeatedly development with improve and mainly the rake teeth structure of workpiece is improved.Connecting plate 1 is connected as a single entity by stay pipe 2 and gear outer case, is received by rotating shaft 8 to constitute the driving rake structure on the connecting plate 1 again.Be welded with dividing plate 11 on the rotating shaft 8, be welded with tooth plate spare 9 between the dividing plate 11, on tooth plate spare 9, be welded with gear piece 10.Workpiece (rake rolls) by drive power by dividing plate 11 act on the tooth plate 9, the be distributed as uniform 30 ° five equilibriums of the tooth plate 9 of integral solder on the rake axle on circumference launch, the teeth directional symmetry, form even plate face layout, make the roll extrusion area cover the pressure effect effectively continuously, stress equalization has kept covering smooth that pressure surface amasss.Tooth plate spare 9 becomes 90 ° to think that with the dividing plate 11 edge degree of depth 65mm is advisable, is that careless effect is pressed in decision in same cross section.After the change, all influential to playing slurry and imbedding grass blade.Prove through test effect: playing the slurry effect behind the tooth depth h increase 10mm obviously increases, and tooth height h increase is limited to 10--15mm.Gear piece 10 angle teeth directional angle β are 100 °--120 ° have determined to divide careless width.But correspondingly influence the consumption size of driving force, the big branch of angle grass is effective and power increases; The β angle reduces, and then power consumption reduces.Variable width to adapt to various types (tractor) requirement, is used more extensive.According to the geology structural property, also can change gear piece 10 height h and teeth directional angle β, guarantee slurry and buried careless effect.The diameter 20--30m that also can add large baffle 11 as required, rotating speed improve 100 right sides of turning left.The utility model can be produced series of products (as 230 types, 160 types etc.) according to user's needs.

Operation and general driving rake are basic identical.Promptly when tractor drives the work of driving rake, hydraulic pressure and suspension arrangement will drive rake and be controlled at the suitable degree of depth, by power transmission power is imported into by power shaft 3, process bevel gear (4,5) drive power transmission shaft 6 passes to gear-box, gear-box reduction gearing 7 passes to spline axle head (rotating shaft) 8, drive tooth plate spare 9 with rolling the rake high speed rotating, wheat straw is pressed in the bottom in paddy field, soil chopped and mud cover wheat straw, the field piece is dragged flat by the pressing plate compacting of back, by the backplate of the side of raking the soil level the field is protected flatly, reached the effect of burying grass, smooth field piece.Cover through practical paddy field that pressure surface is long-pending smoothly to reach 88.3%, coverage rate reaches 85.7%--95%.
