Abstract

The utility model discloses a secondary separating mechanism of a harvester, which comprises a roller, a vibrating screen, a grass feeding plate, a supporting plate, a separating cylinder and a feed inlet, wherein the vibrating screen is arranged on the outer wall of the bottom end of the roller, the roller is arranged on the outer wall of the vibrating screen and is provided with the grass feeding plate, the supporting plate is connected on the outer wall of the bottom end of the grass feeding plate through a bolt, the separating cylinder is rotatably arranged on the outer wall of one side of the roller, the feed inlet is arranged on the outer wall of the bottom end of the separating cylinder, one end of the grass feeding plate is inserted into the feed inlet, the roller and the separating cylinder are cylindrical in shape, the secondary separating mechanism of the harvester is used for secondarily separating grain particles and grass when the harvester harvests rice or wheat, so that the grain particles and the grass are more cleanly separated, the retention rate is improved, the entrainment loss of the grain is reduced, the structure is simple, thus reducing the waste of grains and improving the economic benefit of farmers.

Description

Secondary separating mechanism of harvester

Technical Field

The invention relates to the technical field of auxiliary equipment of harvesters, in particular to a secondary separating mechanism of a harvester.

Background

The harvester was invented by selece mackovick; the harvester is a machine for integrally harvesting crops; harvesting and threshing are completed at one time, grains are collected to a storage bin, then grains are conveyed to a transport vehicle through a conveying belt, or manual harvesting is used, straws of crops such as rice, wheat and the like are laid in a field, and then a grain harvesting machine is used for picking up and threshing; a crop harvesting machine for harvesting grain crop seeds and straws of rice, wheat and the like; comprises a harvester, a windrower, a reaper-binder, a grain combine harvester, a grain thresher and the like; cereal harvesting machine develops on the basis of various reaping, threshing tool, and at the in-process that reaps, needs separating mechanism to separate the corn, but when current harvester reaped rice wheat, can't carry out the secondary separation to the corn after through the cylinder separation and millet grass part, this makes still have a small part of corn on the millet grass, and unable clean separation wastes a lot of grain, can't improve cereal and reserves the rate.

Disclosure of Invention

The invention aims to provide a secondary separating mechanism of a harvester, which aims to solve the problems in the prior art.

In order to solve the technical problems, the invention provides the following technical scheme: the utility model provides a harvester secondary separating mechanism, includes cylinder, shale shaker, send grass board, backup pad, cylinder and feed inlet, install the shale shaker on the bottom outer wall of cylinder, the cylinder is located and installs on the outer wall of shale shaker and send the grass board, bolted connection has the backup pad on sending the bottom outer wall of grass board, rotate on one side outer wall of cylinder and install the cylinder, the feed inlet has been seted up on the bottom outer wall of cylinder, and the one end of sending the grass board is pegged graft in the inside of feed inlet.

Further, the roller and the separating drum are cylindrical in shape.

Further, the grass feeding plate is in a gear shape.

Compared with the prior art, the invention has the following beneficial effects: the grain and straw separating device has the advantages that grain particles and straw are separated for the second time when the harvester harvests rice or wheat, so that the grain and straw are separated more cleanly, the retention rate is improved, the entrainment loss of the grain is reduced, the structure is simple, the operation efficiency is high, the grain and straw separating effect is good, the waste of the grain is reduced, and the economic benefit of farmers is improved.

Drawings

The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention and not to limit the invention. In the drawings:

FIG. 1 is a front view cut-away schematic view of the present invention;

FIG. 2 is a side sectional view of the separator bowl of the present invention;

in the figure: 1. a drum; 2. vibrating screen; 3. a grass feeding plate; 4. a support plate; 5. a separation cylinder; 6. and (4) feeding a material inlet.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a secondary separation mechanism of a harvester comprises a roller 1, a vibrating screen 2, a grass feeding plate 3, a supporting plate 4, a separation cylinder 5 and a feeding hole 6, wherein the vibrating screen 2 is installed on the outer wall of the bottom end of the roller 1, the grass feeding plate 3 is installed on the outer wall, located on the vibrating screen 2, of the roller 1, the supporting plate 4 is connected to the outer wall of the bottom end of the grass feeding plate 3 through bolts, the separation cylinder 5 is installed on the outer wall of one side of the roller 1 in a rotating mode, the feeding hole 6 is formed in the outer wall of the bottom end of the separation cylinder 5, and one end of the grass feeding plate 3 is; the roller 1 and the separating cylinder 5 are cylindrical, so that the secondary separation of the rough grass and the cereals is facilitated; the grass feeding plate 3 is in a gear shape, so that the rough grass can be conveniently fed into the separating cylinder 5; the secondary separation mechanism of the harvester firstly harvests rice or wheat and then sends the harvested rice or wheat into the interior of the roller 1 by the conveying device for threshing, grains and weeds are separated by the vibrating screen 2 after threshing, and the separated grains are separated by the vibrating screen 2 and then are sent by the conveying device after being sorted and leaked; the grains and the rough grass which are not well sorted are conveyed to a separating cylinder 5 through a grass conveying plate 3, then enter the separating cylinder 5 through a feeding hole 6, and then the grains and the rough grass after threshing are subjected to secondary separation through the separating cylinder 5; the rough grass is thrown to the separating cylinder 5 through the centrifugal force generated by the rotation of the separating cylinder 5, and then is discharged by the subsequent grass-passing device, and the grains are leaked to the conveying device through the grass conveying plate 3, so that the secondary separation is completed.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
