Abstract

The utility model relates to a farm machine which is a paddy field oriented driving harrow dedicated to the operation of paddy field harrowing. The utility model has the technical proposal that the output power of a tractor is transmitted to the operating rolling roller composed of a principal axis (10), a rotary table (11) and angle steel (12) through a midpart, a transmission shaft and a lateral transmission box, and the rolling roller breaks up the soil clods and then the harrowed soil is further leveled up by a floor-copying frame arranged on the lateral board (5) through a live axle. Compared with the prior art, the utility model has the advantages that firstly, the utility model has high work efficiency and low fuel consumption. Take the traction of a 65-horsepower tractor as example. The prior spike-tooth harrow can harrow 70 mu land ( roughly 11.55 acres) in 8 hours with a fuel consumption of about 1.1 liters per mu (roughly 0.165 acre), while the paddy field oriented driving harrow of the utility model can harrow 150 mu land ( roughly 24.75 acres) in 8 hours with a fuel consumption of 0.6 liter per mu (roughly 0.165 acre); secondly, the utility model has good operating quality and can save water. The smashing rate of the soil clods and the coverage rate of slurry after a harrowing operation are both over 90 percent and the water in the harrowed field can be maintained for 7 or 8 days and thirdly, thereby the utility model can weed out fresh weeds and thus farm chemicals are saved.

Description

Paddy field driving harrow

Technical field: the utility model relates to a kind of agricultural machinery, is to be exclusively used in the rake the soil level paddy field driving harrow of operation of paddy field.

Background technology: before the utility model, what usefulness was raked the soil level in the paddy field all is spike-tooth harrow, and traction is advanced by the motor vehicle passive type, because the structure of spike-tooth harrow and passive type is dilatory, must repeats twice from longitudinal and transverse two directions and rake the soil level, could be with clods breaking.Even now, the rate that smashes of soil block and the coverage rate of mud also only can reach about 50%.And inefficiency, it is of poor quality to rake the soil level, and fuel consumption is big, and time-consuming, effort is also powerless to the weeds of germinating in addition.

Summary of the invention: for overcoming the deficiency that prior art exists, design of the present utility model is, utilize the outputting power of tractor to give the operation rolling roller that constitutes by main shaft, wheel disc and angle steel with transmission of power, in the process of advancing, soil block is smashed through raising middle flask, power transmission shaft and side biography case; In order further to level land, be the level land plate profiling frame that constitutes by breast boards, soil-suppressing board, control shape pull bar, limit shape pull bar and spring that is connected with the biside plate live axle by a stock behind the operation rolling roller, the ground of harrowing is smooth.Paddy field driving harrow of the present utility model compares with prior art: 1, high efficiency, fuel consumption is few.With 65 horsepowers of tractor-drawns is example, rakes the soil level 70 mu/8 hours about 1.1 liters/mu of oil consumptions with spike-tooth harrow; Rake the soil level with rotating paddy field driving harrow of the present utility model, workload was at 150 mu/8 hours, and fuel consumption is at 0.6 liter/mu.2, operation quality height, and water saving.Because the high speed rotating of operation rolling roller and bump can all smash soil block, the mud scholar in the pasty state, the fragmentation of its soil block and the coverage rate of mud are all more than 90%, reduced water percolating capacity, once can only keep 1-2 days after raking the soil level with prior art, and can remain on about 7-8 days with the ground behind the paddy field driving harrow rake for same water.3, owing to the structure of operation rolling roller and its high speed rotating, it can all be killed germinating weeds bud down on the farm, can save an amount of chemical fertilizer and agricultural chemicals.

Description of drawings: accompanying drawing 1, be the structural representation of paddy field driving harrow of the present utility model.Accompanying drawing 2, be the structural representation of accompanying drawing 1 latus inframedium 5.Accompanying drawing 3, be the structural representation of operation rolling roller.Accompanying drawing 4, be the work schematic diagram of paddy field driving harrow.

Embodiment:, be described below in conjunction with embodiment of the present utility model for further structure and the principle to paddy field driving harrow of the present utility model has detailed understanding:

Embodiment, paddy field driving harrow.

With reference to accompanying drawing 1,2,3,4, the structure of paddy field driving harrow of the present utility model is, the pylon 1 of three-point suspension formula is connected by the hanger of bearing pin with raising middle flask 2, raising middle flask 2 is the raising middle flasks on the commercially available rotovator, in one side of two urceolus that connect in raising middle flask 2 flange both sides, be provided with a power transmission shaft 3 that is connected with raising middle flask 2, both sides at two urceolus are connecting side plate 5 respectively, pass the power transmission shaft 3 that the pressure bearing 4 that is fixed on the side plate 5 and side pass case 6 and be provided with a sprocket wheel 7, chain 8, be fixed on 9 on rolling bearing in two flange holes on the side plate 5, it is the main shaft 10 that is connected by chain 8 with another gear 7 in side passes case 6, by main shaft 10, what be welded with on the main shaft 10 is provided with the operation rolling roller that angle steel 12 that weldering connects constitutes at the wheel disc more than 8 11 with on 11 on two wheel discs by the wheel disc circumference quartering at least, and the angle steel 12 on 11 on adjacent two wheel discs is that a Kongxiang is wrong fixing.In order to prevent the intrusion of dust, be covered with dust cover 13 in its outside to rolling bearing 9.For making the soil behind the rake more smooth, on biside plate 5, connecting breast boards 14 by the 2mm steel plate by a stock live axle, level land plate 15, the control shape pull bar 16 that has spacing catch of Φ 20mm steel pipe, limit shape pull bar 17 and the level land plate profiling frame that the solid spring 18 of cover constitutes on control shape pull bar 16.Breast boards 14, level land plate 15, control shape pull bar 16 and limitting between the shape pull bar 17 connects for live axle.The bolt that is combined as of these other parts of machine is connected and fixed.The mating power 40-50 horsepower of the paddy field driving harrow in the present embodiment, 740 rev/mins of output revolutions, gross weight is 380 kilograms, working width 2400mm, operating efficiency 120 mu/8 hours, fuel consumption is about 0.6 liter/mu.
