Abstract
The invention relates to a concave grid. The concave grid comprises a combined concave grid body, which is combined by a punched plate screen and a grid screen, wherein the concave grid body is arranged on a threshing frame, is positioned below a threshing drum and above a vibrating screen, and is matched with a top cover so as to form a cylindrical threshing room. According to the concave grid, the passing ability is improved, the further generation of crushed straws is reduced, and the resistance of the straws to the threshing drum is reduced, so that the energy consumption is reduced; meanwhile, the possibility of falling of the longer crushed straws on the surface of a sorting screen is reduced, and the grain cleaning difficulty is reduced, so that the grain, which is cleaned in a barn, is cleaner.
Description
Technical field:
The present invention relates to a kind of concave grate, particularly a kind of concave grate being used on combine of relevant threshing.
Background technology
The concave grate of combine is the parts in combine threshing chamber, its effect is that the cereal of threshing is screened, grain and tiny cereal leaf bar leak down to fall within the vibratory sieve of below from the mesh of concave grate, thick cereal leaf bar is thrown out of from the grass outlet of concave grate, obtains cereal.
The threshing concave board sieve of combine generally adopts single sieve aperture form at present, uses a kind of (as Fig. 1) in grid screen, stamped sieve or wire gauze sieve.Wherein the sieve aperture of grid screen is that rectangle or side are square, and it is square that sieve aperture be side is shone in braiding, and stamped sieve is circle, rectangle or square, and sideline of rectangle or square opening and cylinder shaft line parallel.Grid screen intensity is high, and working service cost is low, and screen rate is high, applicability is wide, be to use the widest a kind of threshing concave plate, but grid concave plate percentage of damage is higher.Stamped sieve had both had higher threshing ability, have again lower percentage of damage, but sieving capacity was poorer than grid screen.Wire gauze sieve aspect transaction capabilities between two kinds of forms, but service life is low, thus in operation broken grass easily hang over steel wire in length and breadth infall reduce sieving capacity and threshing ability, production cost is relatively high.
If publication number is the patent of CN201733638U (Fig. 2), the present invention is to provide a kind of threshing concave board sieve, comprise sieve plate and dividing plate, described sieve plate is formed by connecting by stamped sieve and grid screen, wherein stamped sieve is located at feeding mouth one side, attempt to improve concave grate by the method for grid screen and stamped sieve is set at notch board different parts, obtained certain useful effect, but cannot overcome the problem that grid screen percentage of damage is high.Though the notch board of lattice structure can well coordinate threshing cylinder to carry out threshing, also can produce a large amount of crushing straws and fall into sorting screen surface, thereby greatly increase the intractability of sorting screen, causes grain loss; Lattice structure makes stalk larger to threshing cylinder resistance simultaneously, and energy consumption is larger.
Summary of the invention
The invention provides a kind of simple in structure, easily manufactured, working service cost is low, and can take into account preferably the conflicting problems in aspect such as solving threshing performance, percentage of damage, separating power, service life and maintenance cost, reduce a large amount of crushing straws and produce and fall into sorting screen surface by concave grate, thereby reduced, clean difficulty; Improved notch board part the hitting power of crop has been made to difficult de-also threshing easily of kind.
Concave grate in the present invention; position is in the top of threshing cylinder below and reciprocating sieve; described concave grate coordinates formation tubular threshing chamber with top cover; it is characterized in that: described concave grate is comprised of with the punched-plate screen that is arranged on below, threshing cylinder rear end the grid screen that is arranged on the porch of feed roller front end below, and described grid screen and punched-plate screen are arranged in threshing frame along axis direction.
Preferably, described punched-plate screen radially inward direction has lug boss and depressed part, and lug boss and depressed part are in smoothing junction, at depressed part, have through hole.
Preferably, described grid screen is an integral body.
Preferably, described grid screen is formed by connecting by downside detachable apparatus by two of broad ways symmetry or multi-disc grid soldering member.
