Abstract
An airflow conveying high-position discharge mechanism of a combine harvester comprises a push packing auger arranged at the bottom of a grain bin of the combine harvester; a delivery outlet of the push packing auger is connected with a lifting jet, the inlet of which is connected with a high pressure positive blower driven by a power system of the combine harvester, and the outlet of which is connected with a conveying pipe; the upper port of the conveying pipe is communicated with the lateral wall of a shell at the upper part of a cyclonical discharging device in a tangential way. The airflow conveying high-position discharge mechanism has the advantages that the airflow high-position discharge not only has high efficiency, but also has less grain damage in the discharging course; at the same time, the airflow also takes away a plurality of light impurities, thereby greatly reducing the workload for grain following processing. The mechanism has simple structure, easy maintenance, convenient operation, and stable and reliable work.
Description
Technical field
The utility model relates to the high-order discharge mechanism of combine.
Background technology
At present, the high-order discharge mechanism of grain combine, generally adopt by pushing screw feeder and promoting the screw feeder device that screw feeder is formed, the propelling movement screw feeder flatly is installed on the bottom of combine tanker, the lower end import that promotes screw feeder is matched with the outlet that pushes screw feeder, follows the connecing on the grain car of combine thereby the cereal in the combine tanker in time is sent to.The shortcoming that this discharge mechanism exists is, easy damaged cereal in the defeated grain process of spiral screw feeder, cause crack rice, brown rice is more, and defeated, unloading speed is slower, functional reliability is not good enough yet.
Summary of the invention
The purpose of this utility model, provide a kind of defeated, unloading speed fast, to the high-order discharge mechanism of the few high efficiency combine of cereal damage.
Technical solution of the present utility model is: it comprises the propelling movement screw feeder that is installed on combine tanker bottom, and be connected with injector at the delivery outlet that pushes screw feeder, the injector import is connected with the high pressure positive blower that is driven by the combine dynamical system, injector outlet is connected with carrier pipe, the tangent connection of top cylinder lateral wall of the upper port of carrier pipe and cyclone feeder.
The beneficial effects of the utility model are: the high-order unloading of air-flow is the efficient height not only, and unloading process cereal is damaged few, and air-flow has also been taken away many light impurities simultaneously, has alleviated cereal subsequent treatment workload greatly.This apparatus structure is simple, and maintenance is easy, and easy to operate, working stability is reliable.

Fig. 2 is a propelling movement screw feeder structural representation of the present utility model.
Fig. 3 is an injector structural representation of the present utility model.
Fig. 4 is the widely different adapter structure schematic diagram of carrier pipe of the present utility model.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
The bottom of combine tanker 4 is equipped with level and pushes screw feeder 3, its delivery outlet flange 10 is connected with the vertical pipeline section 11 upper oral part flanges 16 of the inverted T-shaped pipe injector 2 of its below, the horizontal inlet pipeline section 12 of inverted T-shaped pipe injector 2 is a reducing pipe, its reducing 13 is positioned at the level pipe middle part, be provided with in the vertical section 11 towards horizontal pipeline section Way out, and the lower end is connected in the flow guiding inclined plate 15 of reducing pipe choke top, injector 2 level pipe imports are connected with the high pressure positive blower 1 that is driven by the combine dynamical system, the outlet pipe section 14 of injector 2 connects carrier pipes, and the top cylinder lateral wall is tangent is communicated with for the upper port of carrier pipe and cyclone feeder 9.Carry out unloading for carrier pipe being cooperated better connect the grain car, carrier pipe can be designed to down canned paragraph 5 and last pivoted arm section 7, be connected by widely different adapter 6 between last pivoted arm section 7 and the following canned paragraph 5.The widely different adapter 6 of present embodiment be by rotating disk flange 23, plane promote bearing 18, and pallet flange 22, platen 17 constitute, rotating disk flange 23 is fixed in the lower port of pivoted arm section 7 on the carrier pipe, pallet flange 22 is fixed in the upper port of canned paragraph 5 under the carrier pipe, platen 17 is connected to a fixed by the connecting plate 20 of its connecting plate 19 with the pallet flange, is separately installed with plain thrust bearing 18 between rotating disk flange 23 and platen 17 and the pallet flange 22.In addition, pallet flange 22 inner edges also are fixed with the protection back-up ring 21 of protection plain thrust bearing 18.
During the unloading operation, make the engine of combine drive high pressure positive blower 1 high speed rotating generation high pressure draught, the level that starts the tanker bottom simultaneously pushes screw feeder 3, cereal promptly from push that the screw feeder outlet enters injector 2 and along flow guiding inclined plate 15 landings to reducing 13, the high pressure draught that is blown out from reducing is carried secretly to mix and is blowed to carrier pipe, enter cyclone feeder 9 along canned paragraph under the carrier pipe 5, last pivoted arm section 7, under centrifugal action, grain falls into and connects the grain car, and air-flow is then being carried light impurities secretly and upwards discharged from the center riser 8 of cyclone feeder 9.
