Abstract

A no-smashing plough-equipped straw returning machine consists of an original plough and a set of straw chopping and fertilizer sowing mechanism added on the original plough. The straw returning machine is characterized in that the equipped straw chopping and fertilizer sowing 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 of the plough, a hub in front of a plough share, a saw blade on the hub, replaceable tool noses welded with alloy on the saw blade, a straw pressing wheel, a fertilizer hopper on a plough rack, a discharging box and a chain. The straw returning machine has the advantages of simple and reasonable structure and convenience in use; in addition, the straw chopping, fertilizer sowing, 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, benefits are brought to the farmers, and the straw returning machine is an ideal no-smashing plough-equipped straw returning machine.

Description

Exempt to pulverize plough and join straw cutting apparatus

One, technical field:

The present invention relates to a kind of crushing straw field-returning machine of exempting from, particularly a kind of pulverizing plough of exempting from is joined straw cutting apparatus.

Two, background technology

Present rural area maize straw large tracts of land is the field also, all adopts to pulverize first and plows afterwards or two links of rotary tillage, pulverizes link and exists following shortcoming: the one, and the locomotive resistance is large especially during crushing straw, oil consumption is many, cost is high, and much dilatory owner 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 compaction, particularly clayed ground, completely is not only hard but also large soil block behind the plough, and is very unfavorable to raking the soil level, sowing; The 3rd, most farmers adopts rotary tillage behind the first crushing straw, because rotary tillage is too shallow, only is 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 kind 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 invention is to provide a kind of fitting over and exempt from also field and sow the agricultural machinery of chemical fertilizer of crushing straw on original plough, this machine is exactly to sow chemical fertilizer, straw-returning, arable land and agricultural machinery all over the body, its can be disposable with stalk need not pulverize imbed underground, bring convenience for raking the soil level, sowing, in order to overcome the deficiencies in the prior art.

Purpose of the present invention can reach by following embodiment, this field-returning machine is furnished with straw cutting mechanism by former plough and forms, it is characterized in that join the universal joint that has in the straw cutting mechanism behind the tractor output shaft, gear-box speed changer on the plough front-axle beam, jackshaft on the plough crossbeam, wheel shaft before the ploughshare, saw cutter on the wheel shaft, the point of a knife of saw cutter is removable, be welded with alloy block on the point of a knife, the saw cutter outside is the stalk pinch roller, fertiliser bucket is arranged on the plow frame, blanking box, chain, its power transmission relationship is that tractor output shaft is passed to speed changer to power by universal joint, through sheave, after the belt secondary speedup, transmission of power is to jackshaft; Jackshaft is through sheave, and after three grades of speedups of belt, to the wheel shaft before each ploughshare, the saw knife up speed on the wheel shaft is rotated transmission of power.Plough is at the plough wheel of middle drive plow frame one side that moves ahead, the chain gear wheel is equipped with in plough wheel inboard, through chain transmission of power to the fertiliser bucket on the plow frame, through blanking box, fertilizer is sowed uniformly before each ploughshare, along with the straw cutting of saw hilt gear before the plough leg, the mud bar that moment is started by ploughshare is buried action to stalk and chemical fertilizer and is finished.

Four, description of drawings

Fig. 1 is unitary construction schematic diagram of the present invention.

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

Fig. 3 is the saw cutter schematic diagram of Fig. 1 of the present invention.

Five, embodiment:

As Figure 1-3, this field-returning machine is furnished with straw cutting mechanism by former plough and forms, and it is characterized in that institute joins and tractor output shaft is arranged through universal joint 1 in the straw cutting mechanism, the gear-box speed changer 2 on the plough front-axle beam, jackshaft 3 on the plough crossbeam, wheel shaft 4 before the ploughshare, the saw cutter 5 on the wheel shaft, removable point of a knife 6 on the saw cutter, the stalk pinch roller 7 in the saw cutter outside, fertiliser bucket 8 on the plow frame, chain 9, blanking box 10; Its power transmission relationship is that tractor output shaft passes through universal joint 1, transmission of power to speed changer 2, after tooth belt secondary speedup, transmission of power is to jackshaft 3, jackshaft is through sheave, after three grades of speedups of belt, give wheel shaft 4 before each ploughshare transmission of power, the saw cutter 5 of High Rotation Speed on the wheel shaft, plough is at the plough of middle drive plow frame one side that moves ahead wheel, and the chain gear wheel is equipped with in plough wheel inboard, through chain 9 transmission of power to the fertiliser bucket 8 on the plow frame, through blanking box 10, fertilizer is sowed uniformly before each ploughshare, and along with the straw cutting of saw hilt gear before the plough leg, the mud bar that moment is started by ploughshare is buried action to stalk and chemical fertilizer and is finished.

Advantage of the present invention is: it is to sow chemical fertilizer; straw-returning; the disposable agricultural machinery of finishing of the three-phase work of plowing; simple in structure; rationally; easy to use; can overcome the shortcoming that former crushing straw brings; can shorten the farming time in autumn; sowing when being conducive to rob; and every mu can be saved wheat seeds 5-10 jin; can Energy Saving; with regard to crushing straw and two links of plowing, remove this link of crushing straw from, every 0.07 hectare can be saved diesel oil 5-7 jin; can follow traditional method of cultivating; improve seeding quality, protection of the environment is the regeneration product of desirable existing straw-returning.

Claims
