Abstract
The utility model relates to a semi-feeding mechanical rice and wheat threshing machine, which belongs to the technical field of agricultural machinery. An enclosed roller with arch-shaped teeth comprises a roller shaft, spoke disks fixed at the two ends f the roller shaft, and circular threshing cylinders with arch-shaped teeth, which are arranged and fixed on the outer circumference of the spokedisks and are formed of a plurality of arc-shaped plates with arch-shaped teeth by assembly. The semi-feeding mechanical rice and wheat threshing machine for rice and wheat threshing operation can solve the problems of the prior semi-feeding mechanical rice and wheat threshing machine adopting an enclosed roller with arch-shaped teeth, including high vibration during operation, high shedding liability of the arch-shaped teeth, poor safety, difficult and troublesome roller installation, maintenance and replacement, and so on.
Description
Technical field
The utility model relates to agricultural machinery technological field, especially a kind of adopt closed arch dental roller partly feed motor-driven rice-wheat thresher.
Background technology
The closed arch dental roller of existing employing partly feed motor-driven rice-wheat thresher; the round bow tooth threshing tube of its closed arch dental roller is to be formed by cylinder and the seam of bow tooth; cylinder is to be formed by steel plate circle system; because the accuracy of circle is difficult to reach designing requirement during the circle system; so carry out relatively difficulty of cylinder static balance work; because the degree of balance is poor, vibration is bigger during the cylinder rotation.And the bow tooth is the surface that is welded in cylinder, cause burn-through easily and produce poor weld, when carrying out rice-wheat threshing work, the bow tooth in work stressed or and when being hit easy sealing-off drop, thereby generation unsafe factor, because round bow tooth threshing tube is monoblock type, making, install adjust, maintenance, when changing all than more complicated and difficulty.
Summary of the invention
Provided by the utility modelly partly feed motor-driven rice-wheat thresher; the cylinder round accuracy when making that mainly solves the round bow tooth threshing tube of existing closed arch dental roller is difficult for reaching requirement and difficult assurance of bow tooth welding quality; and round bow tooth threshing tube making, install adjust, maintenance, when changing than the problem of more complicated and difficulty.
In order to address the above problem; the scheme that the utility model is taked is: thisly partly feed motor-driven rice-wheat thresher; its closed arch dental roller comprises drum shaft; be fixed on the spoke dish and the round bow tooth threshing tube that is fixed on the spoke dish cylindrical at drum shaft two ends, the described round bow tooth threshing tube that is fixed on the spoke dish cylindrical is merged by polylith camber bow tooth plate to be formed.
The above-mentioned polylith camber bow tooth plate that is merged the round bow tooth threshing tube of composition can be two and be merged composition; Three are merged composition; Four are merged composition; Five are merged composition; Six are merged any in the composition.
Above-mentioned camber bow tooth plate is made up of bow tooth and the seam of camber plate, with bolted on the spoke dish cylindrical that is installed in the drum shaft two ends.
Adopted the utility model of such scheme compared with prior art to have following beneficial effect:
1, the camber plate can be used the pressing equipment processing, can guarantee circular arc type shape and each design size more accurately, has reduced degree of unbalancedness, has improved the exchange performance, the cylinder vibration is reduced, and improved production efficiency greatly and reduced production cost.
2, because the camber plate is that intensity height and area are little through punch forming, flexible type does not adopt when surface soldered bow tooth and can strengthen throat depth, because welding is convenient, the camber plate is difficult for by burn-through.Employing can be molten with installing to the whole welderings in the position, bow tooth root end of camber plate bottom surface when camber plate bottom surface welding bow tooth, thereby improved the impact resistance of bow tooth greatly, improved usage safety performance.
3, because the round threshing tube of monoblock type is designed to be merged by polylith camber bow tooth plate forms, then manufacture, install adjust, maintenance, and the user changes voluntarily and is very easy to conveniently saving of work and time.
Description of drawings
Fig. 1 is the front view of closed arch dental roller of the present utility model.
Fig. 2 is the cutaway view at Figure 1A-A place.
Embodiment
In order more to understand design feature of the present utility model and implementation to intuitive and convenient, the utility model is described in further detail below in conjunction with the accompanying drawing example:
Among Fig. 1, the embodiment shown in Figure 2; this partly feeds motor-driven rice-wheat thresher; the drum shaft 1 of its closed arch dental roller, two ends are mounted with 2 spoke dishes 2, and arc plate 4 is merged on the cylindrical that is installed in spoke dish 2 by Luo bolt 6 with the bow tooth plate 3 that 5 seam of bow tooth are formed.
Claims (3)
1, a kind ofly partly feeds motor-driven rice-wheat thresher; its closed arch dental roller comprises drum shaft, be fixed on the spoke dish at drum shaft two ends and be fixed on circle bow tooth threshing tube on the spoke dish cylindrical, and it is characterized in that: the described circle bow tooth threshing tube that is fixed on the spoke dish cylindrical is merged by polylith arc bow tooth plate to be formed.
2, according to claim 1ly partly feed motor-driven rice-wheat thresher, it is characterized in that: the described polylith arc bow tooth plate of forming circular bow tooth threshing tube that is merged is two and is merged composition; Three are merged composition; Four are merged composition; Five are merged composition; Six are merged any in the composition.
3, describedly partly feed motor-driven rice-wheat thresher according to claim 1,2, it is characterized in that: described arc bow tooth plate is made up of bow tooth and arc seam, with bolt on the cylindrical of the spoke dish that is installed in the drum shaft two ends.
