Abstract
The utility model discloses a rotary threshing plate thresher, which carries out structure improvement on the basis of the existing thresher. Such as, the top cover of the utility model is provided with a windshield; the feeding end of a cylinder of the utility model is additionally provided with a spiral threshing plate; a wedge-shaped gap is formed between a concave plate sieve and the cylinder at the feeding inlet. The structure improve of the utility model makes the production efficiency of the thresher be improved. Besides, the utility model has the advantages of thorough threshing and low broken rate; the environment for operators at the feeding inlet is improved. Each index of the utility model is superior to similar threshers by testing.
Description
The utility model belongs to a kind of thresher of agricultural machinery.
Along with the development thresher machine degree of agricultural production is also improving constantly; at present more advanced is motor-driven cylinder sheller; although this thresher is than the original manual foot pedal threshing machine advanced person who uses; but still need further to improve indexs such as threshing speed and threshing performance, to satisfy the demands.
The utility model is in order to improve the production efficiency of thresher better, the threshing performance of cereal, and reduce its percentage of damage and improve operating personnel's working environment, thereby a kind of spiral threshing board thresher has been proposed.
Spiral threshing board thresher is to carry out structural improvement and realize goal of the invention on existing machine props up the basis of thresher.
Accompanying drawing 1 is the utility model structural representation sketch
Accompanying drawing 2 is the threshing cereal turnover route schematic diagram of the utility model accompanying drawing 1A-A section
Accompanying drawing 3 is the utility model threshing roller structure schematic diagram
Among the figure: 1 is grass outlet; 2 is top cover assembly; 3 is threshing board; 4 is roller assembly; 5 is the concave grate assembly; 6 is barge board; 7 is main feeding platform assembly; 8 is " wedge shape " gap; 9 is fan assembly; 10 is the screw feeder assembly; 11 is road wheel; 12 is support assembly; 13 is the seed slide plate; 14 for supporting iron; 15 for paying feeding platform assembly; 16 is drum pulley; 17 is main bearing seat; 18 is the spoke dish; 19 are the threshing toothholder; 20 are the threshing tooth; 21 are the awl circle; 22 is main shaft; 23 is fan; 24 is guide plate.
It is total that the utility model includes top cover assembly 2, the cylinder of former thresing machine One-tenth 4, concave grate assembly 5, master pay feeding table assembly 7, fan assembly 9, stir Dragon assembly 10 component parts such as grade. And top cover assembly removes original grass outlet 1, leads Outside plate 24, also newly established barge board 6 and be positioned at top cover import department, And be " △ " shape; Roller assembly is except this belt wheel 16 of original cylinder, main shaft Bearing 17, spoke dish 18, threshing toothholder 19, threshing tooth 20, cone circle 21, main Axle 22 outer also at the feeding end of cylinder, be that threshing tooth is three helixes and arranges it First position is provided with three rotary threshing plates 3; The concave grate assembly is to notch board A feeding mouth end place, sieve position changes and is arranged as tangent line former garden week and arranges, and makes this position Concave grate and cylinder between have one " wedge shape " feeding gap; And recessed The sieve aperture of plate sieve is changed into from the feeding end by former unified aperture and pursuing to the grass-feeding end aperture Cumulative big. All the other are main pay feeding table assemblies, screw feeder assembly, fan assembly, Screw feeder assembly and frame combination are all same as the prior art.
The utility model embodiment:
Crop on the feeding platform; being pushed into feeding mouth by the feeding operator advances; enter sheller unit under the air-flow suction in thresher; crop is subjected to the spiral threshing board and the spike-tooth radiation of high speed rotating and beats and hit, and simultaneously for the helical movement under the guide plate effect, and crop is hit repeatedly, throwing; grain just splits away off and falls from the notch board sieve aperture; selection by winnowing is blown away clever shell, and grain is sent outside the machine by the screw feeder device, and cane then spues from the grass outlet of cylinder end.The utility model makes this machine have original effect in the course of the work to the structural improvement of former thresher.One, three spiral threshing boards also produce the axial advance speed that axial flow is accelerated crop except that playing equally the flailing action, and produce suction at the feeding mouth place, have improved feeding speed.Its two, designed " wedge shape " gap can make crop more successfully enter sheller unit.They are three years old, " △ " barge board of setting up in top cover import department, the top-down high velocity air that shelves have produced when having lived the threshing cylinder rotation blows to feeding mouth, can make the feeding mouth place keep negative pressure, not only help the crop feeding, and improved operator's environment, the fragment of cereal, dust can not fly out from feeding mouth, pollutes human body.
The utility model after tested, every indexs such as its production efficiency, threshing performance, cleannes, percentage of damage all are better than domestic similar type, are the thresher of rice wheat dual-purpose.
Claims (4)
1, a kind of by top cover assembly 2, roller assembly 4, concave grate assembly 5, the main pair of spiral thresher that feeding platform assembly 7, fan assembly 9, screw feeder assembly 10 are formed, it is characterized in that: its top cover assembly includes barge board 6; Roller assembly includes spiral threshing board 3; The concave grate of concave grate assembly changes at feeding mouth end place and is arranged as tangent line former garden week and arranges, and makes to exist one " wedge is opened " to feed gap 8 between this part concave grate and the cylinder.
2, spiral threshing board thresher according to claim 1, it is characterized in that: barge board 6 is positioned at the import department of top cover, and is " △ " shape.
