Abstract

A plough matched straw returning machine consists of an original plough and a set of straw chopping mechanism added on the original plough. The plough matched straw returning machine is characterized in that the matched straw chopping mechanism is provided with a universal joint at the back of an output shaft of a tractor, a transmission gearbox on a front beam of the plough, an intermediate shaft on a girder, a chopping box in front of a plough share and a main rolling shaft, an auxiliary rolling shaft and a flail in the box. The utility model has the advantages of simple and reasonable structure and convenient use; in addition, the straw chopping, ploughing and straw burying can be completed at one time, the oil is saved, the labor and time are also saved, the burden of farmers is reduced, the utility model also brings benefits to the farmers and is an ideal plough matched straw returning machine.

Description

Plough is joined straw cutting apparatus

One, technical field:

The utility model relates to a kind of straw cutting apparatus, and particularly a kind of plough is joined straw cutting apparatus.

Two, background technology:

At present maize straw large tracts of land field also in rural area is all adopted and is pulverized earlier two links of afterwards plowing, and the pure link of powder exists following shortcoming: the one, and the locomotive resistance of pulverizing is big especially, and oil consumption is many, the cost height, much tractors would rather rotary tillage, the crushing straw of also being unwilling; The 2nd, the crushing straw locomotive walks twice down on the farm, makes loose soil compactionization, and particularly clayed ground completely is not only hard but also big soil block behind the plough, and is very unfavorable to harrowing, broadcasting; The 3rd, most peasants adopt rotary tillage behind the crushing straw, because rotary tillage is too shallow, only are that stalk and the soil of pulverizing mixes, and after planting germination rate is low, and the amount of tillering is little, every mu of multicast wheat seeds 5-10 jin, and a little less than the seedling, this is the deficiency that has straw cutting apparatus now.

Three, summary of the invention:

The purpose of this utility model provides a kind of plough and joins straw cutting apparatus, and this field-returning machine fits over existing going up with plough the corn field of any lodging is directly executed plough, disposable maize straw is imbedded under, for rake, broadcast and bring convenience, in order to overcome the deficiencies in the prior art.

The purpose of this utility model can reach by following embodiment: this field-returning machine is furnished with the stalk shut-off mechanism by former plough and forms, it is characterized in that join the universal joint that has on the stalk shut-off mechanism behind the tractor output shaft, gear-box speed changer on the plough front-axle beam, jackshaft on the plough crossbeam, cut-out case before the ploughshare, two roller bearings in a slice stationary knife and front and back are housed in the case, the front and back roller bearing all is equipped with flail knife, its power transmission relationship is that tractor output shaft is passed to speed changer to power by universal joint, through gear, after the belt secondary speedup, transmission of power is given jackshaft, jackshaft is through sheave, after three grades of speedups of belt, give main roller bearing in the cut-out case before each ploughshare transmission of power, the other end of main roller bearing is the chain gear wheel, drive negative lacquer axle through chain, together with the flail knife high speed rotating, the stalk of retaining before the plough leg cut off, and the mud bar that moment is started by ploughshare is buried action and is finished.

Four, description of drawings:

Fig. 1 is the utility model unitary construction schematic diagram.

Fig. 2 is the side schematic view of Fig. 1.

Fig. 3 is for cutting off case chain one side figure.

Fig. 4 is for cutting off case follower one side figure.

Five, embodiment:

Shown in Fig. 1-4, this field-returning machine is furnished with the stalk shut-off mechanism by former plough and forms, it is characterized in that institute joins and tractor output shaft is arranged through universal joint 1 on the stalk shut-off mechanism, gear-box speed changer 2 on the plough front-axle beam, jackshaft 3 on the plough crossbeam, cut-out case 4 before the ploughshare, main roller bearing 5, negative roller bearing 6, chain 7, flail knife 8, its power transmission relationship is that tractor output shaft passes through universal joint 1, power is passed to speed changer 2, after tooth belt secondary speedup, power is passed to jackshaft 3, jackshaft is through sheave, after three grades of speedups of belt, give main roller bearing 5 in the cut-out case before each ploughshare transmission of power, the other end of main roller bearing is the chain gear wheel, through chain 7, drive negative roller bearing 6, together with flail knife 8 high speed rotating, the stalk of retaining before the plough leg to be cut off, moment is buried by the mud bar that ploughshare starts.

The utility model can be according to what of ploughshare, adjust the wheel number on the jackshaft and cut off the number of case, and belt or chain number be relative set also.

During use, and plow equally at ordinary times, the tractor driver need constantly watch the rear attentively, should reach the requirement of plowing, note the situation of burying of stalk again, according to the thick rare and landlord's of plough method, the speed of a motor vehicle, physical features, soil moisture content, weather, stalk requirement, suitably comprehensively adjust, to guarantee cultivating quality.
