Abstract
The invention discloses a symmetric reverse stubble cleaner and relates to field husbandry and straw turnover machinery. An intermediate box directly drives left and right tool shafts to reversely rotate; a small plowshare is arranged below the front of the intermediate box; a vertical distance between a cross beam and the tool shafts is 250-400mm; a hood and the inner side of a fence are 30-80mm away from tool tips; the fence has cells at 50-140mm intervals. The symmetric reverse stubble cleaner is used for dry field plowing and straw turnover; the defects that the tool shafts in the existing side-drive reverse stubble cleaner bend and break easily, the cleaner has high failure rate, the cleaner is not bilaterally balanced and poor in operating quality, soil and straw jamming easily occurs are overcome.
Description
Technical field
The present invention relates to a kind of farming operation machinery, is specifically the symmetrical expression reversed stubble cleaner for glebe straw returning operation.
Background technology
Using reversed stubble cleaner to carry out glebe straw returning and plough whole ground, is a kind of conventional operational method.Current reversed stubble cleaner is all side transmission, by middle housing by transmission of power to side casing, by gear train in side casing, drive a cutter shaft to counter-rotate operation.Because side casing is mounted in a side of facility, thereby both sides weight is uneven, affects in the course of the work operation quality; And it is very large to bear moment of torsion during the farming of rimmer knife axle, easily cause cutter shaft bending, fracture, dependability is poor.In addition, also easily there is the clogging of earth and stalk in current reversed stubble cleaner.So a lot of customer requirements improve reversed stubble cleaner.
Summary of the invention
The technical problem to be solved in the present invention is the weak point that overcomes existing side transmission reversed stubble cleaner, provides a kind of and can improve operation quality and dependability, avoids the symmetrical expression reversed stubble cleaner of earth and straw blockage phenomenon simultaneously.
Technical scheme of the present invention is: symmetrical expression reversed stubble cleaner, comprise middle housing, crossbeam, cutter shaft, hood, fence, its improvements are that described cutter shaft is divided into symmetrically arranged left and right cutter shaft, and middle housing directly drives left and right cutter shaft reversion, and middle housing front lower place is provided with little colter.
The inner of described left and right cutter shaft is connected with middle housing driving member, and outer end is bearing in respectively on the left side plate being connected with crossbeam; The vertical range of described crossbeam and cutter shaft is 250～400mm; Described hood and fence are divided into two of left and right, bend to the circular-arc of center line and cutter shaft coaxial line, have 30～80mm spacing between the point of a knife on its medial surface and cutter shaft; The grid distance of described fence is 50～140mm, and fence lower end is adjacent to ground; The front lower end of described hood is higher than cutter shaft axis 120～220mm.
The invention has the beneficial effects as follows, without side casing, utilize middle housing directly to drive left and right cutter shaft, be about to a cutter shaft and be divided into two of left and right equal in length cutter shaft, left and right cutter shaft is installed in respectively the both sides of middle housing.Effective like this stationarity that increases facility, improves operation quality.Also it should be noted that: general reversed stubble cleaner load is all very large, under equal cultivation width condition, reversion cutter shaft when being rotated in the forward is loaded and is exceeded 1/3rd.Because when cutter shaft is rotated in the forward, tulwar digs out earth directly and dishes out backward from cutter shaft below, and the direction of rotation of cutter shaft is consistent with the direction of rotation of tractor tire, has increased tractor thrust forward; And cutter shaft when reverse rotation, after the earth that tulwar digs out must be thrown to from the top of cutter shaft, the direction of rotation of cutter shaft is contrary with tractor tire direction of rotation, has increased tractor resistance forward.For example the dilatory function of 80 horsepowers drives the rotovator of 2.5 meters of fabric widths, but only can drive the reversed stubble cleaner of 2 meters of fabric widths.The cutter shaft overall length of the reversed stubble cleaner of 2 meters of fabric width sides transmission is 2.2 meters of left and right, if be divided into two cutter shafts in left and right, every cutter shaft length is 1.1 meters of left and right.Short sword axle has improved anti-twisting property, is not prone to bending and phenomenon of rupture, thereby improves dependability.In middle housing front lower place, be provided with little colter, can avoid adopting after two cutter shafts, the operation blind area that casing below occurs.
In the present invention, the spacing of the spacing of crossbeam and cutter shaft crossbeam and cutter shaft when adopting tower structure, thereby cutter shaft is when counter-rotate, the earth of routing up and stalk just can not stop up because being subject to stopping of cruciform bracing.Front portion above the cutter shaft of left and right is provided with hood, rear portion and the cutter shaft rear side of top are provided with fence, hood and fence Dou Cheng garden camber, the cutter shaft of making peace greatly forms a concentric garden, hood and fence medial surface and point of a knife maintain 30 to 80 millimeters of spaces, and the earth that tulwar digs down and stalk fly to fence through this space along hood.Fence grid bends to garden camber with round steel, and the interval of grid and grid is between 50 to 140 millimeters and be evenly fixed on and on cross bar, form fence; Stalk after ploughing and earth are thrown to below and the grid that flies out through hood and point of a knife space, and larger clod and longer stalk are fallen below fence.Because tractor is walked forward, so the earth that can be dished out overrides.The front lower end of hood is higher than 120 to 220 millimeters, cutter shaft central horizontal line, and its effect is that earth and the stalk that tulwar digs down has certain space to enter hood, avoids blocking up of earth and stalk.

Fig. 2 is A-A place cutaway view in Fig. 1.
Embodiment
Referring to accompanying drawing, in symmetrical expression reversed stubble cleaner, middle housing 1 directly drives 4 reversions of left and right cutter shaft, and cutter shaft direction of rotation is contrary with tractor tire direction of rotation, and middle housing front lower place is provided with little colter 7.One end, inner side of left and right cutter shaft is connected with middle housing driving member, and one end, outside is bearing in respectively on the left side plate 6 being connected with crossbeam 2.The vertical range 280mm of crossbeam 2 and cutter shaft 4.Divide the left and right hood 3 and the left and right fence 5 that are located at middle housing both sides to be circular-arc, center line and cutter shaft coaxial line, have 50mm spacing between the point of a knife on its medial surface and cutter shaft, the grid distance of fence is 90mm, fence lower end is adjacent to ground, and the front lower end of hood is higher than cutter shaft axis 160mm.
