Description

Baby combine

The utility model relates to a kind of agricultural grain header, is specially adapted to the harvesting of mountain area, nearly area, mountain range and splat interplanting crops.

In technique known, usually the grain header that adopts is large-scale combine, this machine high efficiency, but because of type huge, have following some not step: 1, type is huge, be only applicable to the harvesting of Plain forward (FWD) monoculture, and harvested soil by wheel roll very real, be unfavorable for the sowing of autumn crop.2, reaping apparatus complexity needs long conveying plant and the multiple attached parts equipment manufacturing cost height that helps from gathering in threshing, is difficult for popularizing at agricultural material.3, the thresher in the reaping apparatus; the general screw type drum threshing that adopts; be to carry out operation by screw rod and rubbing of recessed grid in the cylinder; because screw rod is to be in parallel position with drum shaft, the cane of crops is easy to be wrapped on the cylinder, makes the stuck commentaries on classics of cylinder motionless; injustice has influenced operating efficiency; face and be prone to the unclean situation of threshing, particularly to moist crops, this phenomenon is even more serious.

The purpose of this utility model be overcome the deficiency of above-mentioned existing technology and provide a kind of simple in structure, in light weight, small and exquisite flexibly, and can realize harvesting, and wide adaptability, economical and practical baby combine with landform and all kinds of interplanting crops.

Realize that the scheme that the purpose of this utility model is taked is: this machine is to be converted by known small hand tractor, with the original position fore-body start and and base move and install to fuselage afterbody, the front portion is provided with frame, is packed on the base by securing member.Additional reaping apparatus is by the function of its each several part; be assembled on the frame successively; by grain lifter, cutter, workbench, grab into device, thresher, carrier pipe, grain collecting bucket and form; wherein; grain lifter is packed on the forebay; the workbench of dovetail groove shape is fixed with gripper and is connected with a cutter and a grain machine respectively, and off line is packed on the frame, and sidepiece connection carrier pipe also leads to and is positioned at the aggregate bin that machine adds the top.

According to the baby combine that said structure is made, it is fast to have the speed of taking off, and the speed of taking off is fast, the effect that threshing performance is high, it is simple in structure, make low, in light weight, volume is little, wide accommodation, be easy to popularize at agricultural material.

Following sharp drawings attached further describes embodiment of the present utility model.

Fig. 1 is the complete machine structure schematic diagram of utility model.

Fig. 2, Fig. 3 are grain lifter structural representations in the utility model.

Fig. 4, Fig. 5 are feed rake structural representations in the utility model.

Fig. 6, Fig. 7, Fig. 8 are cylinder ratch schematic diagrames in the novel middle detachment machine of this reality.

Describe one referring to Fig. 1 and had the baby combine that additional reaping apparatus and engine are installed in fuselage afterbody.Engine 13 has been adorned at the rear portion of fuselage, becomes belt speed case 11, hand steered 12, driving wheel 14, base 15 etc.Additional reaping apparatus comprises holding up and shows device 2, cutter 3, workbench 4, grabs into device 5, thresher 6, carrier pipe 9, grain collecting bucket etc.Connect workbench 4, cutter 3 etc. successively.Cutter 3 adopts known configurations, and different is, cutting blade is set up widened section, is made of two-section, and the junction of two-section is connected with screw with the connecting plate that is easy to dismantle.Be the normal rotation that guarantees these each parts of machine and the requirement of different rotating speeds, the running part of this machine mainly is to utilize the V-belt transmission, has only the drum shaft exception, because drum shaft is vertically settled, the direction of rotation of drum shaft becomes 90 ° with the direction of rotation of engine, so the bevel gear transmission of the type of belt drive of drum shaft, concrete route: an engine 13-clutch 18-gap bridge axle 19-bevel gear 20-drum shaft 61-fan 7 '-flood dragon 8 '; Another route gap bridge axle 19-grabs into device 5 cutters 3.

Hold up and show device 2

The operation principle of this machine: power drives to hold up hold up when showing that device work rotatablely moves through belt pulley and shows that device 2 will pull the crops of holding up and back tilt on the cutter 3, and cutter 3 is cut easily.Crops after cutter 3 cuttings are swung in the dovetail groove of workbench 4 successively; by grabbing of installing on it crops are dragged into device; send in the thresher; separate green hand's cane by outside the drum outlet discharge machine; clean seed is through flood dragon 8, leaf one's duty 8 ' be thrown into grain bucket 10 by carrier pipe 9, by people's frock income bag.

Referring to Fig. 2 Fig. 3, holding up diagrammatic sketch device 2 is two mutually perpendicular cross frameworks 21 being made by steel pipe, is welded on to hold up and shows on the device axle 22, and an end of axle is equipped with belt pulley 22, and two ends are connected on the forebay 16 by bearing 23.(referring to Fig. 1).

In conjunction with Fig. 1, referring to Fig. 4, Fig. 5, Fig. 5 is the end view of Fig. 4.Gripper 5 is made single frame formula rectangular frame 51 by steel pipe, for prolonging the coverage that contacts with crops, reinforcement is to the conveying effect of crops, and the both sides of framework 51 are respectively installed with profile of tooth lever arm 52 and compression spring 53, and wherein compression spring 53 is distributed on 4 angles on framework 51 both sides.Framework 51 is provided with central shaft, be by two semiaxis 55,56 ' weldering built in framework 51 two ends,, be fixed on the workbench 4 label 55,55 ' be belt pulley by bearing 54.

In conjunction with Fig. 1, referring to Fig. 6, Fig. 7, Fig. 8, thresher vertically is placed on the frame 1, and is connected with workbench 4.By ratch type cylinder, fan 7, flood dragon 8 and impeller 8 ' form, be provided with cylinder ratch 61 in the cylinder, drum shaft 62, bearing 65,65 ', cylinder ratch 61 1 ends be the both sides of half garden arc (referring to Fig. 6) arc be provided with fixing hole 64,64 ', the other end is a cuboid, and per two rooted tooth bars match, and has in arms mutually to be fixed on the drum shaft 62.Cylinder ratch 61 is at least 6, be made into 3 pairs in the shape of a spiral line arrange and to be packed in (referring to Fig. 5) on the drum shaft 62, introduce a fine variety arrangement, the one, rotation steadily, torque ratio is more even, the 2nd, can improve grabbing to crops into speed and reliability.In addition, the center out of plumb of the installation site of cylinder ratch 61 and drum shaft 62 has a hypsokinesis angle, and its effect is good to the guidance quality of object, and frictional force is little, makes cylinder when work rotation light, reaches the purpose of saving power.Because the hypsokinesis of cylinder ratch and in the shape of a spiral line be discharged to this specific character, when taking off moist crops, effect is more outstanding, and wide type centrifugal fan 7 also is housed in the thresher 6, shell is provided with the air-flow plate (not shown), to adapt to the needs of different crops.Be positioned at the bottom of thresher 6; On same axis, be equipped with flood dragon 8 and impeller 8 ', flood dragon 8 the seed flood dragon can be gone into impeller 8 ' in, utilize impeller 8 ' centrifugal force with seed through carrier pipe 9, be thrown into grain bucket 10, by people's frock income bag.
