Description
Technical field
The utility model belongs to the tillage equipment in the agricultural machinery, is mainly used in rotary tillage, the hack of the former stub land in paddy field after soaked, stirs slurry, presses a stubble operation pacifically.
Background technology
At present, the ground making of paddyfield of China is normally turned over or the rotovator rotary tillage with uncovering plough earlier, and soaked then (being commonly called as the soaked field) utilizes the water harrowing wheel to roll repeatedly again, finishes hack, the operation of rake slurry of ground making of paddyfield.Its major defect is that drought is turned over, revolved and water two subjobs of raking the soil level, the cost height, and efficient is low.Next is that the water harrowing wheel operation quality of raking the soil level is poor, the shallow inequality of slurry layer depth, and the fertilizer of metalling run out, the water in field temperature is low, influences growing of paddy rice, has hindered the raising of rice yield.
Summary of the invention
The purpose of this utility model is exactly problem and the shortcoming that exists at prior art; design provides a kind of paddy field former stubble ground harrowing and leveling machine; this machine can finish with once advancing the former stub land in paddy field the rotary tillage of band water, hack, stir slurry, press a stubble operation pacifically, reach and improve operation quality and operating efficiency, reduction operating cost, conserve water resource, protection soil aggregate and nutrient component, promotion rice growth, provide qualified whole ground condition, and the purpose of final realization Rice Production increasing both production and income for follow-up mechanized planting.
Basic design of the present utility model is, connection hauling plate pressure regulation assembly on last hanger bracket, and this hauling plate pressure regulation assembly is made of pedestal, locking clamp, locking spring, control lever, swing arm, pressing spring, pull bar; The rubber connecting plate fuses rear cowl and upper cover plate; Large and small sprocket wheel splined hole in the transmission chain cover is measure-alike, and two teeth number of sprocket differ 1 tooth; Even, the symmetrical seam handle of a knife of its cutter shaft tangent to periphery direction trousers in cutter shaft assembly upper edge install the right side, a left side cultivated rake cutter respectively in a pair of handle of a knife trousers; The right side, a left side cultivated rake cutter are on the cutter shaft assembly with the multi-head spiral line structure of middle part symmetry arranges installation, and right, the left rake cutter arranged spaced of ploughing, and so far constitutes the former batch of ground harrowing and leveling machine in paddy field.
The utility model general structure design is reasonable; go to the field and once can finish multinomial associating multiple operation, have the operating efficiency height, operation quality is good, operating cost is low, the characteristics of conserve water resource, the formation that helps soil aggregate and protection, promotion rice growth.
