Abstract

The utility model discloses a beet harvester and belongs to agricultural harvesting machinery. A digger blade of the harvester is arranged at a machine frame arranged in front of a tractor. A grain lifter and a leaf clamping chain are arranged above the digger blade. A pair of leaf cutting rollers with axial ribs and a beet conveyor belt are arranged under the leaf clamping chain. A lift conveyor and a slideway which rises above the top of the tractor are connected at the back of the leaf clamping chain. A separating guide groove is arranged at the rear part of the tractor and under the slideway. A step topping device is arranged under the guide groove. The loading lift conveyor is connected to the back of the guide groove. The harvester divides the beets into a plurality of grades according to the size, and tops different grades of beets with different arc-shaped cutters, with high-quality and quick operation, small loss and high production efficiency.

Description

Sugarbeet harvester

1, technical field: the utility model relates to a kind of harvest machinery, particularly a kind of machinery of gathering in the crops beet.

2, background technology: existing sugarbeet harvester has and simply digs loose machine, cuts beet digger behind the cherry, also has and cut cherry and cut the top and excavate the combined harvester of working continuously.Fairly simple excavator can alleviate the labour intensity of hand digging, but follow-up cuts cherry, cut the top and be still the operation of taking a lot of work very much.The large-scale sugarbeet harvester of import not only costs an arm and a leg, and also is not suitable for the local agriculture requirement and the production scale in rural area, is difficult to promote.

3, summary of the invention: the purpose of this utility model is a kind of sugarbeet harvester of design, and it is according to the agriculture requirement design of locality, and integration of operation has applicability preferably.Its technical scheme is: select the crawler tractor of driver's cabin in the engine front for use.Digger blade is contained on the frame in tractor the place ahead, and there are grain lifter and folder cherry chain in digger blade top, have below the folder cherry chain a pair of tape spool to fin cut cherry roller and beet conveyer belt, elevator that connects later and slideway rise to the tractor top.At the tractor rear portion, separating guide is arranged below the slideway, separating guide divides two-layer up and down, and two-layer up and down have an opposite incline direction.Beet subdivided gap is just arranged at guide groove bottom, upper strata.Be that ejection device is cut in the beet classification below the guide groove, the back connects truck elevator.2-10 clamping chain group of carrying beet backward arranged side by side about the beet classification is cut ejection device and had, each clamping chain group has 2-5 the clamping chain that distributes up and down.Each clamping chain group covers one section different clamping size, and the clamping size of the clamping chain of this group lays respectively at this group with up big and down small order and covers in the size section.There is a unsteady rotation to cut the top cutter above the clamping chain at each.Rotation is cut the top cutter by on the circumference that is installed in the ringwise cutter hub in two ends and the hollow revolving body formed of equally distributed circular arc blade, leaves the gap between adjacent knife blades.On the gap blade at the minimum place of revolving body diameter, a small knife edge vertical with blade is arranged, connect two adjacent blades.

This sugarbeet harvester is divided into a plurality of grades with the beet size, with the curved knife of different curvature the beet of each grade is cut the top, and work quality is good, and speed is fast, lose little, the production efficiency height.

4, description of drawings: Fig. 1 is the overall structure schematic diagram of sugarbeet harvester.Fig. 2 is the structural representation of beet grading plant.Fig. 3 is the structural representation that the top cutter is cut in rotation.

5, embodiment: Fig. 1 has provided the embodiment of a sugarbeet harvester.Select for use driver's cabin to be used as power at the crawler tractor 14 of engine front.There are eight digger blades 2 to be horizontally installed on the frame 15 in tractor the place ahead, can lifting under hydraulic jack control.Each digger blade is aimed at delegation's beet, is used for beet is dug pine.The digger blade top has grain lifter 1 that the beet cherry is propped up by folder cherry chain 3 clampings rising, and beet is extracted from soil.Have a pair of tape spool to the cherry roller 4 of cutting of fin the beet cherry to be cut off below the folder cherry chain, beet drops on the following conveyer belt 5, be transported to connect later about on two elevators 6, rise to again the tractor top about continue in two slideways 7 mobile backward.At the tractor rear portion, separating guide 8 is arranged below each slideway, separating guide has the two-layer up and down of reverse inclination direction, and beet subdivided gap is just arranged at upper strata guide groove bottom, with the first part level of beet., fallen lower floor's guide groove less than the beet of first subdivided gap and be directed to the opposing party by upper strata guide groove guiding one side greater than the beet of first subdivided gap.Be that ejection device is cut in the beet classification below each separating guide.Eight beet clamping chain groups of carrying backward arranged side by side about the beet classification is cut ejection device and had, per four clamping chain groups are facing to a separating guide.Each clamping chain group has 4 clamping chains 10 that distribute up and down.Clamping chain is installed on the sprocket wheel 12 of chain rivet 13.Each clamping chain group covers one section different clamping size, and the clamping size of four clamping chains of this group lays respectively in the size section of this group covering with up big and down small order.As shown in Figure 2, connecing below separating guide coils 16, and the beet of upper strata separating guide landing drops on the two groups of clamping chains in left side, and the beet of lower floor's separating guide landing drops on the two groups of clamping chains in right side, and it is carried backward.There is a rotation that can fluctuate to cut top cutter 9 above the clamping chain at each.Rotation is cut the top cutter by on the circumference that is installed in the ringwise cutter hub 19 in two ends and the hollow revolving body formed of equally distributed circular arc blade 18.Connect support by bearing on the mounting groove 21 of annular cutter hub, annular cutter hub is driven to rotate by belt pulley 20.Leave the gap between adjacent knife blades, cutting on the minimum gap blade of locating of top cutter diameter in rotation has a small knife edge vertical with blade 17, connects two adjacent blades.Beet backward in the moving process rotation cut the top cutter and move to forward position beet top from the back light is cut on the beet top, enter the hollow cavity of cutting the top cutter after the root scurf that is reamed is cut off by small knife edge and discharge from both sides.Cut the hopper of beet below fall the clamping chain rear end on top, the truck elevator 11 that is connected is later sent in the compartment of transport vehicle.Truck elevator can turn round by 180 degree, makes things convenient for never ipsilateral entrucking of transport vehicle.
