Description
Technical field
The utility model belongs to corn threshing technical field, relates in particular to a kind of harvesting corn seed separating mechanism.
Background technology
China's corn machine is received the two kinds of modes that mainly contain: the one, and adopt harvesting debarker to take fruit ear and peel off bract, fruit ear is by husker sheller threshing after airing, and this mode functional reliability is better, but all swivel links are many, grain loss is larger, has increased cost and has been unfavorable for large-scale production; Be with grain combine by the direct harvesting corn seed of the corn annexes such as separating mechanism that changes the outfit, this mode efficiency is high, and has improved the availability of grain header, therefore, directly harvesting corn seed more and more becomes a kind of trend that corn machine is received.
At present the threshing concave plate mechanism for corn kernel mainly contains two types: a kind of is to take patent: 201320875300.5 grid-type concaves that are representative, by the diaphragm plate of band steel moulding, intersecting the round steel that diameter is 6-16mm forms, sieve aperture is rectangle, sieve aperture rate is 40%-70% left and right (the sieve aperture gross area accounts for the ratio of the notch board gross area), threshing performance is high, screen rate is high, wide adaptability, but diaphragm plate has corner angle and protrudes notch board body, and then cause percentage of damage higher, when in receiving especially for kernel direct, corn kernel moisture content is higher, and the separating mechanism intensity of this structure is poor, easy deformed damaged, cause maintenance cost high, to take patent: the 201120234108.9 punched holes type notch boards that are representative, hole is circular hole or strip hole, aperture is 15-17mm, sieve aperture rate is 32% left and right, manufacturing process is simple, and threshing performance is high, and percentage of damage is low, but corn kernel trafficability characteristic is poor, screen rate is low, and whole notch board and miscellaneous part be connected as a single entity, and stability and servicing ease are poor, and cylinder-concave clearance is non-adjustable, in use, there is larger limitation.
Utility model content
The purpose of this utility model is to provide a kind of harvesting corn seed separating mechanism, is guaranteeing under the prerequisite that threshing performance is high and corn kernel percentage of damage is low, realizes the object that improves separating mechanism stability, seed trafficability characteristic and be convenient to maintenance.
For solving the problems of the technologies described above, the technical solution of the utility model is: harvesting corn seed separating mechanism, comprise installing rack, described installing rack is provided with the notch board suitable with threshing cylinder, on described notch board, horizontal array has the elliptical aperture that some row vertically arrange and supply corn kernel to pass through, and the described elliptical aperture of adjacent every row is crisscross arranged; Be positioned at the described installing rack that crop flows to a side and be provided with rebound, described rebound is connected setting with described notch board.
As a kind of improvement, described installing rack comprises suitable with described threshing cylinder profile and is arranged on the side plate at described notch board two ends, described in two, between side plate, be provided with the gripper shoe be arrangeding in parallel, described in two, between gripper shoe, be provided with some midfeathers and some diaphragm plates arranged in a crossed manner and for carrying, described midfeather and described diaphragm plate are arranged on the below of described notch board.
As further improvement, described rebound is arranged on wherein described in one in gripper shoe; Described notch board is arranged on described installing rack by coupling assembling.
As further improving, described in two, the two ends of side plate are equipped with for regulating the installing hole of cylinder-concave clearance between described notch board and described threshing cylinder.
Owing to having adopted technique scheme, the beneficial effects of the utility model are:
Because installing rack is provided with notch board, and notch board is provided with elliptical aperture, thereby utilize the characteristic of punching hole type notch board, guaranteed that corn kernel percentage of damage is low, under the condition of the high effect of threshing performance, by installing rack, promoted working strength, dependability and the stability of this releasing mechanism, and be easy for installation and maintenance, safeguard; Because the elliptical aperture of adjacent every row is crisscross arranged, thereby utilized fully the space on notch board, optimized the arrangement mode of elliptical aperture (being sieve aperture), improved sieve aperture rate, and then guaranteed the trafficability characteristic of sieve performance and corn kernel; Because installing rack is provided with rebound, thereby be convenient to crop by rebound, flow to next parts, improved the fluency of equipment work.
Because installing rack comprises side plate and gripper shoe, and be provided with midfeather and diaphragm plate between two gripper shoes, thereby further improved support strength and dependability, and then improved service life, reduced production and application cost.
Because side plate is provided with installing hole, thereby be convenient to regulate cylinder-concave clearance between notch board and threshing cylinder, solved traditional threshing concave plate and there is in the use circumscribed problem.
