Abstract

A plough matched straw returning machine is composed of an original plough matching with a straw cutting mechanism. The utility model is characterized in that the matching straw cutting mechanism is provided with a universal joint positioned behind an output shaft of a tractor, a middle shaft positioned at front beam of the plough and a wheel shaft positioned in front of a plough share. The blade arranged on the wheel shaft and one side of the front wheel shaft of the plough share are provided with a fixed blade that can up and down move and a straw pressing plate. The utility model has the advantages of simple and reasonable structure, convenient usage, and can combine the plough, straw cutting and straw burying together, save the oil, save the labor and time, thus the utility model 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:

Present rural area maize straw large tracts of land is the field also, all adopts and pulverizes earlier two links of afterwards plowing, and pulverizes link and exists following shortcoming: the one, and the locomotive resistance of crushing straw is big especially, oil consumption is many, the cost height, a lot of tractor masters 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 pears 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 corn stalk 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 stationary knife moving up and down that a side of jackshaft, wheel shaft, the saw cutter on the wheel shaft and the ploughshare front axle before the ploughshare of the universal joint that has on the stalk shut-off mechanism behind the tractor output shaft, the gear-box speed changer on the plough front-axle beam, plough crossbeam is provided with, sheath is housed on the stationary knife, stationary knife is near the saw cutter, a plurality of holddown grooves are arranged on the stationary knife, the stalk pressing plate is housed before the ploughshare; Its power transmission relationship be tractor output shaft by universal joint power pass to speed changer, speed changer is given jackshaft transmission of power through break-in and speed change by chain, jackshaft is passed to saw cutter on the ploughshare front axle to power by chain, drive the saw cutter and rotate, the cooperation of the stalk pressing plate that the saw cutter is equipped with before by stationary knife and ploughshare is finished the cut-out of stalk and is buried action.

Chain drive on the utility model speed changer and the jackshaft can change belt transmission into.。

The utility model is according to what of ploughshare, and the drive on the jackshaft, wheel shaft, saw cutter, stationary knife, sheath, pressing plate are established corresponding some; Belt or chain number be relative set also.

Advantage of the present utility model is simple and reasonable for structure, easy to use, can overcome the shortcoming that former crushing straw brings, and can shorten the farming time in autumn, sow when helping robbing, and every mu can be saved wheat seeds 5-10 jin; Can economize on oil, with regard to the crushing straw and two links of plowing, remove this link of crushing straw from, save diesel oil 5-7 jin for every mu; Can follow traditional method of cultivating, improve seeding quality, reduce damage by disease and insect and agricultural chemicals usage amount, the protection environment is for the good harvest of following season of wheat lays the first stone.

Five, embodiment:

Shown in Fig. 1-6, this field-returning machine is furnished with the stalk shut-off mechanism by former plough and forms, it is characterized in that join the stationary knife moving up and down 4 that a side of jackshaft 3, wheel shaft 8, the saw cutter 6 on the wheel shaft 8 and the ploughshare front axle before the ploughshare of the universal joint 1 that has on the stalk shut-off mechanism behind the tractor output shaft, the gear-box speed changer 2 on the plough front-axle beam, plough crossbeam is provided with, sheath 5 is housed on the stationary knife 4, stationary knife 4 is near saw cutter 6, a plurality of holddown grooves are arranged on the stationary knife 4, stalk pressing plate 7 is housed before the ploughshare; Its power transmission relationship be tractor output shaft by universal joint 1 power pass to speed changer 2, speed changer 2 is given jackshaft 3 transmission of power through break-ins and speed change by chain, jackshaft is passed to saw cutter 6 on the ploughshare front axle to power by chain, drive saw cutter 6 and rotate, the cooperation of the stalk pressing plate 7 that saw cutter 6 is equipped with before by stationary knife 4 and ploughshare is finished the cut-out of stalk and is buried action.

All chain drives of the utility model can substitute with belt transmission.

The utility model is according to what of ploughshare, and the drive on the jackshaft 3, wheel shaft 8, saw cutter 6, stationary knife 4, sheath 5, pressing plate 7 are established corresponding some; 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.
