Abstract

The utility model discloses a small combine, which comprises a machine frame, a traveling device positioned on the machine frame, a conveyance device, a disengaging and separating device and a barn. Compared with existing small combine, the threshing principle of the utility model is: when the paddy is fed to the threshing cylinder longitudinally via the conveyance device, the convex tooth of the threshing cylinder beats the paddy in fast speed, then the grains separate from the stalk and fall to the barn via a screening net, finally the stalk is conveyed to a stalk propeller and is thrusted out. Different from the existing technology that the stalk moves in high speed with the threshing cylinder, the utility model reduces the energy consumption and realizes the making of smaller and lighter combine.

Description

A kind of baby combine

Technical field

The utility model relates to a kind of grain header, relates in particular to a kind of baby combine that collects harvesting, threshing function.

Background technology

The rice standing grain of being cut by rice cutter when the baby combine that generally use in present rural area is worked is sent into sheller unit by after stirring collection through conveying plant.Sheller unit is by the propeller of the oblique shape biceps of last cornice, and the screen cloth of below and middle threshing cylinder are formed.During threshing, with the cylinder high speed rotating and in screen cloth and tiltedly collision back and forth between the shape muscle rib propeller, grain falls into silo through screen cloth to the rice standing grain under action of centrifugal force in the threshing drum, and straw progressively is extruded into outlet by muscle rib propeller and discharges.This grain header is because working method, the live load of its high-speed stirred formula are big, specified down in identical work, need to consume bigger energy, require to use engine, bring the problems such as restriction that are subjected to the natural conditions in geographical and field when causing the walking of facility heaviness than high-power.

The utility model content

The purpose of this utility model is to provide a kind of energy consumption low, lightweight baby combine.

The technical solution of the utility model is: baby combine comprises frame and rack-mounted running gear, rice cutter, dials standing grain and conveying plant, threshing and separator and silo.Running gear comprises two front-wheels and a trailing wheel, dials standing grain and conveying plant, by two cylinders, cover thereon following conveyer belt and by three cylinders, cover the last force feed band composition that is provided with the triangularity shape of dialling straw thereon.Threshing and separator are by the threshing cylinder that is provided with double wedge in front, and one of back has the cylinder (dogstail propeller) of helical form muscle rib, and the dogstail outlet of following screen cloth, the grain-blocking cover of top and side is formed.Threshing and separator are arranged on the rear, upper end of dialling standing grain and conveying plant.

During the utility model work, dial straw standing grain is dialled behind conveying plant, rice cutter is cut off straw.Rice standing grain quilt group straw is clamped to be sent to following conveyer belt and is broken away from and separator (at this moment the rice standing grain is to be vertical from beginning to end orderly) simultaneously, the threshing roll double wedge that the standing grain fringe is at first run up during threshing hits, grain breaks away from straw, fall into silo through screen cloth, straw continues to be sent to spiral propeller and is extruded outlet.

Compare with existing baby combine, threshing principle of the present utility model is the rice standing grain that the quick strike of threshing roll double wedge is vertically sent into, make grain break away from straw, prior art then is after the rice standing grain is sent into the threshing drum, cylinder runs up the rice standing grain and constantly friction strike collision screen cloth and tiltedly shape propeller with breaking away from, and makes grain break away from straw.Because the utility model is not the working method that adopts sheller unit stirring-type in the prior art, the rice standing grain is again that vertically contact breaks away from the cylinder double wedge, it is quite small breaking away from the double wedge of cylinder and the friction of straw, so little energy that consumes during work, specified down in identical work, can use the engine of less horsepower, make facility associated components size reduce weight saving.
