Abstract

The utility model discloses a semi-feeding combine harvester. A threshing device is positioned at the front part of the semi-feeding combine harvester and is formed by that a plurality of threshing cylinders are combined side by side. A separation distance is arranged between the edges of each two adjacent threshing cylinders to form tunnels. The cylinders are all sealed by a casing of which the shape is matched with the shapes thereof. The side surface of the rear lower part of the casing is provided with a feeding port and a reeling device. A corn cutter which is arranged on the rear surface of the threshing device adopts the combine harvesting mode that threshing is carried out before the cutting is carried out. The semi-feeding combine harvester is capable of completing the semi-feeding harvesting work without needing a grain fastening and conveying device and has the advantages of wide harvesting applicability, low grain loss rate, etc.

Description

Semi-feeding combine harvester

The utility model relates to a kind of grain combine.

Present known half-feeding combine, comprise cutter, fastening conveying plant, sheller unit, engine etc., its combining mode is cutting on one side, with fastener the cereal bottom of just having cut off is vised on one side, with conveying plant the cereal that vises is sent in the sheller unit to adopt again and partly feed the mode threshing, to obtain grain and complete straw.The shortcoming of this half-feeding combine is: (1) fastening transport conveyor constructions complexity; (2) harvesting bad adaptability; (3) the cereal percent of loss is higher.

The purpose of this utility model, providing does not a kind ofly need fastening conveying plant just can finish half feeding harvesting, harvesting wide adaptability, new head-feed combine harvester that the grain loss rate is low.

For achieving the above object, the utility model adopts the harvesting mode of cutting behind the early threshing, specifically, exactly sheller unit is arranged at the front of grain header, cutter is placed the back of this sheller unit.Sheller unit is combined side by side by several threshing cylinders, drives by a central shaft.Evenly, the edge of adjacent roller leaves certain spacing to each cylinder, constitutes a tunnel at interval.The body seal that each cylinder matches with it by profile has spout in the rear lower side of shell.The next door of each spout all is provided with one and dials the standing grain device, and the standing grain fringe is laterally dialled in spout.The back of each cylinder all is furnished with grain conveyor, and the grain of threshing is transferred out rapidly.The inlet front lower place of each access adit, all corresponding configuration one nearside divider.This machine is to finish combining work like this, nearside divider is along with grain header advances, divide the ridge with the cereal in field, cereal is mobile backward by tunnel inlet separately then, when arriving spout, through dialling laterally stirring of standing grain device, the standing grain fringe is sent into separately threshing cylinder, grain ear under the strike of the bow tooth of arranging in the shape of a spiral by threshing, the grain of taking off is promptly transferred out by grain conveyor, moves after being continued by the straw of threshing, is set at the cutter cuts of sheller unit back, along with constantly advancing of grain header, just can continuously carry out this harvesting work.

Can cereal successfully enter spout in the tunnel, dials the standing grain device and played crucial effects.Simple group standing grain device can adopt a curved baffle, and the more complicated little straw shift wheel that can adopt the band moving tooth is dialled the standing grain effect in order to improve, also can both and usefulness.

Each threshing cylinder can dispose a grain conveyor respectively, but, so just seems too numerous and diverse, therefore, preferably adopts a conveying plant to carry all threshing grain.A kind of comparatively ideal conveying plant is at conveyer belt of the back of each threshing cylinder horizontally set, grain is laterally transported on one side, and then by another conveyer belt that is connected with this conveyer belt it is vertically transported to the rear.These two conveyer belts also can use auger conveyor (screw feeder) to substitute.

This half-feeding combine can be designed to the suspended structure with existing tractor use, also can be designed to self-powered self-propelled structure, if adopt a kind of structure in back, at least need two road wheels and a tail wheel, should be designed to these two road wheels of clutch simultaneously with these two matching used gearboxes of road wheel, also can distinguish these two road wheels of clutch, its main purpose is to be convenient to the field turn to flexibly.

The advantage of the utility model half-feeding combine is: (1) need not be provided with fastening conveying plant, just can finish half feeding combining work; (2) be not subjected to the restriction of grain yield, density, height, the harvesting wide adaptability; (3) percent of loss of harvesting grain is low.

Embodiment to the utility model half-feeding combine is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the mansion TV structure schematic diagram of the utility model half-feeding combine.

Fig. 2 is the side-looking structural representation of the utility model half-feeding combine.

By Fig. 1,2 as can be known, the sheller unit of present embodiment is positioned at the front portion of whole loom, is combined side by side by three threshing cylinders ［ 1 ］, drives with threshing driving wheel ［ 2 ］.Evenly, the edge of adjacent roller leaves a determining deviation to each threshing cylinder, constitutes a tunnel ［ 3 ］ at interval, and the shell that each cylinder matches with it by profile ［ 4 ］ sealing has a spout ［ 5 ］ in the rear lower side of shell.Wherein rightmost shell the right and left all has spout.On the next door of each spout, all be provided with one and dial standing grain baffle plate ［ 6 ］, the standing grain fringe is laterally dialled in spout.In the back lower place of each threshing cylinder, horizontally set the grain conveyer belt ［ 7 ］ of a sealing and another be connected with this conveyer belt, vertically carry the conveyer belt ［ 8 ］ of the sealing of grain.The front lower place of each access adit has all correspondingly disposed a nearside divider ［ 9 ］.Corn cutterbar ［ 10 ］ is arranged on the back of sheller unit, and corresponding configuration have two the shop standing grain pieces ［ 11 ］, the straw that this two boards will have played under will cut is drawn in to central authorities by the right and left respectively, and smooth be layered on the ground effect.The vehicle frame of grain header ［ 12 ］ is combined by hollow Zuo Liang, right beam and the back rest, left lateral travelling wheel ［ 13 ］ and right lateral travelling wheel ［ 14 ］ lay respectively at the middle part of Zuo Liang and right beam, respectively are furnished with a gearbox ［ 15 ］ and ［ 16 ］, these two gearboxes are designed to clutch road wheel separately simultaneously, also clutch road wheel separately separately.Engine is positioned at the left back portion of vehicle frame, by driving wheel ［ 17 ］ power is passed to main drive wheel ［ 18 ］, and then, power is passed to Left Drive axle that passes left beam and the right power transmission shaft that passes right beam respectively by two pairs of bevel gears ［ 19 ］ and ［ 20 ］ passing the power transmission shaft of the back rest and be positioned at these power transmission shaft two ends.Right power transmission shaft is passed to right gearbox by a pair of bevel gear with power, drive the right lateral travelling wheel, by another bevel gear is driven the belt pulley ［ 21 ］ of vertical grain conveyer belt simultaneously, the Left Drive axle is passed to left gearbox by a pair of bevel gear with power, drive the left lateral travelling wheel, directly drive the belt pulley ［ 22 ］ of horizontal grain conveyer belt simultaneously, in addition, also power is passed to the center driven wheel ［ 23 ］ that is positioned at left gearbox side by another bevel gear.Center driven wheel one side drives the threshing driving wheel, and one side drives cutting driving wheel ［ 24 ］, is positioned at eccentric ratio device on the cutting driving wheel and will rotatablely moves and be transformed into the round cutting movement of cutter.The tail wheel of grain header ［ 26 ］ is positioned at the left back, is furnished with an elevating lever ［ 27 ］, in order to regulate the height of sheller unit, is convenient to the different cereal of harvesting height.Driver's seat ［ 28 ］ is positioned at the afterbody of grain header, is convenient to driver's operation.
