Description

The multifunctional rotary tillage combine

The utility model relates to a kind of agricultural rotovator, relates to a kind of multifunctional rotary tillage combine in particular, belongs to a kind of improvement of rotovator.

Usually, before the sowing of farmland, all need the soil is carried out several farm works such as rotary tillage, stubble-cleaning, when carrying out the rotary tillage operation,, make the soil, field obtain sufficient scarifying by being installed in the rotary blade on the rotary tillage shaft.When carrying out the stubble-cleaning operation, rotary blade on the rotary tillage shaft is changed the stubble-cleaning cutter, just can carry out field stubble-cleaning operation, the patent No. is that 96238992.7 rotovator just belongs to this series products, and the rotating speed of this rotovator is single, can not speed change, though changed the stubble-cleaning cutter on rotary tillage shaft, but it is slow because of the rotary tillage shaft rotary speed of rotovator eventually, can only smash the partly loose root stubble of quality, the harder root stubble of some quality is still stayed influences normal farming in the ground, makes troubles to farm work.

The purpose of this utility model provides a kind of multifunctional rotary tillage combine, and it can not only carry out the rotary tillage operation to the field, and can also smash the harder root stubble in field easily, and the realization stubble-cleaning is resigned from office and return home.

The purpose of this utility model is to realize like this, it includes transmission case, rotary tillage shaft, rotary blade, stubble-cleaning cutter and tie ridger, it is characterized in that on transmission case, being provided with former and later two power shafts, there is a conical tooth inner end of each power shaft, the rotating ratio of two conical tooths does not wait, and power shaft connects by two corresponding with the transmission case front and back respectively power shaft axis holes of bearing; Also have a splined shaft in transmission case, splined shaft is connected with two symmetrical axis holes about transmission case top by bearing, has a spur gear, two ends also to connect a bevel gear that differs in size respectively at the middle part of splined shaft; The awl tooth of two power shafts respectively with the engagement of the bevel gear at splined shaft two ends, the spur gear at splined shaft middle part meshes with the carrier gear that the transmission case middle part is provided with.

Owing to adopted such scheme, make the power shaft that has increased a high rotating ratio in the transmission case, at this moment drive rotary tillage shaft with the power shaft of high rotating ratio and rotate, by the stubble-cleaning cutter just can be easily with stay the field, comprise that harder root stubble thoroughly smashes, realized that stubble-cleaning resigns from office and return home.And can also carry out rotary tillage, dark pine, ridging or stubble-cleaning, dark pine, the synchronous farming of ridging.Having characteristics simple in structure, a tractor serves several purposes, is a kind of novelty and the rotary tillage machine tool that shows unique characteristics.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the concrete structure schematic diagram of multifunctional rotary tillage combine;
