Abstract
The utility model discloses a maize picker threshing concave, including two connecting plates, two install a plurality of arc reinforcing plates between the connecting plate, the reinforcing plate along the extending direction of connecting plate arranges two the tip of connecting plate do not is equipped with one the reinforcing plate, every the both ends difference fixed connection of reinforcing plate is two on the connecting plate, all one side of reinforcing plate indent is equipped with a plurality of grids, the extending direction of grid with the connecting plate is the same, adjacent two it is gapped between the grid, every the grid all with all the reinforcing plate is connected, partly embedding of grid in the reinforcing plate, remaining another part is located outside the reinforcing plate, the grid is located the cross -section of the outer part of reinforcing plate be the arc, and the threshing concave of above -mentioned structure is during with threshing cylinder interact, and it is broken to reduce the seed grain, moreover the use intensity height of product.
Description
Technical field
The utility model relates to maize harvesting machine technical field, particularly relates to the threshing concave plate in maize harvesting machine.
Background technology
Current maize harvesting machine is mainly divided into fruit ear to gather in the crops with grain harvest two kinds, compared with fruit ear reaping machine, corn kernel harvester can save peasant labor force greatly, reduces labour intensity, enhance productivity, higher income can also be provided for grain header user simultaneously.But corn kernel harvester often percentage of damage is higher, be only difficult to produce a desired effect by regulating rotation speed of drum, the frequency of the threshing concave plate of corn stigma blocking is simultaneously high, cleaning difficulty, and the threshing concave plate structure at present for corn kernel mainly contains two types:
One is grid-type concave, and intersecting diameter by the shaping diaphragm plate of band steel is that the round steel of 6-16mm forms, diaphragm plate arranged direction be drum shaft to, round steel arranged direction is that cylinder is tangential.
One is punched holes type notch board, and hole is circular hole or strip hole, and aperture is 15-17mm, and sieve aperture rate is about 32%.
For grid-type concave, be diaphragm plate with threshing cylinder site of action, diaphragm plate has corner angle and protrudes notch board body, and during threshing, the corner angle of notch board impact comparatively large to seed, and then cause percentage of damage higher, more serious when special corn kernel moisture content is higher.The separating mechanism intensity of this structure is poor in addition, and easy deformed damaged causes maintenance cost high.During threshing, corn stigma is easier to block notch board, and cleaning difficulty.For punched holes type notch board, corn kernel is poor by property, and screen rate is low, and whole notch board and miscellaneous part are connected as a single entity, stability and servicing ease poor, use and there is larger limitation.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of Stability Analysis of Structures, the low threshing concave plate of destruction of corn kernel.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of maize harvesting machine threshing concave plate, comprise two connecting plates, between two described connecting plates, some arc stiffeners are installed, described stiffener arranges along the bearing of trend of described connecting plate, the end of two described connecting plates is respectively equipped with a described stiffener, the two ends of stiffener described in every root are fixedly connected on two described connecting plates respectively, the side of all described stiffener indents is provided with some grizzly bars, the bearing of trend of described grizzly bar is identical with described connecting plate, gap is had between two adjacent described grizzly bars, grizzly bar described in every root is all connected with all described stiffeners, a part for described grizzly bar embeds in described stiffener, remaining another part is positioned at outside described stiffener, the cross section that described grizzly bar is positioned at the part outside described stiffener is arc.
As a kind of preferred version, described grizzly bar is the round steel that diameter is greater than 8 millimeters, and the half of described round steel diameter embeds described stiffener.
As a kind of preferred version, described stiffener and connecting plate weld together, and described grizzly bar and stiffener weld together.
Owing to have employed technique scheme, by the grid that grizzly bar and stiffener formation corn kernel pass through, and the cross section that grizzly bar is positioned at the part outside described stiffener is arc, therefore, when using in maize harvesting machine, the part that threshing cylinder is only positioned at the arc outside stiffener with grizzly bar interacts, thus it is more steady to the impact of corn kernel, the destructive power that seed receives is little, percentage of damage reduces thereupon greatly, and the two ends of stiffener are connected with connecting plate, and a part for grizzly bar is embedded in stiffener, can Stability Analysis of Structures be made, there is higher intensity.
Because described grizzly bar is the round steel that diameter is greater than 8 millimeters, and the half of described round steel diameter embeds described stiffener, the diameter of round steel is larger, both the intensity of product can have been ensured, and the probability that corn stigma can be made to be wound around round steel reduces greatly, threshing concave plate blocking probability reduces, and cleaning frequency is well below common notch board, and notch board clearance time reduces greatly.

Embodiment
As shown in Figures 1 to 4, a kind of maize harvesting machine threshing concave plate, comprise two connecting plates 1, between two connecting plates 1, some arc stiffeners 2 are installed, as shown in Figure 3, the bending direction of stiffener 2 matches with cylinder, these stiffeners 2 arrange along the bearing of trend of connecting plate 1, the end of two connecting plates 1 is respectively equipped with a stiffener 2, the two ends of every root stiffener 2 are fixedly connected on two connecting plates 1 respectively, by being welded together between stiffener 2 and connecting plate 1, stiffener 2 and connecting plate 1 constitute the framework of threshing concave plate, the side of all stiffener 2 indents is provided with some grizzly bars 3, the bearing of trend of grizzly bar 3 is identical with connecting plate 1, gap is had between two adjacent grizzly bars 3, grizzly bar 3 can be uniformly distributed on stiffener 2, also can be non-uniform Distribution, every root grizzly bar 3 is all connected with all stiffeners 2, a part for grizzly bar 3 embeds in stiffener 2, remaining another part is positioned at outside stiffener 2, the cross section that grizzly bar 3 is positioned at the part outside stiffener 2 is arc.
In order to manufacture and draw materials conveniently, grizzly bar 3 is greater than the round steel of 8 millimeters for diameter, and the half of round steel diameter embedding stiffener 2, as shown in Figure 4, stiffener 2 is provided with the groove 21 of semicircular arc, and round steel is arranged in groove 21, and welds together with stiffener 2.
Threshing is carried out by grizzly bar 3 and cylinder being interacted, and the cross section of part that grizzly bar 3 is positioned at outside described stiffener 2 is arc, therefore, when using in maize harvesting machine, more steady to the impact of corn kernel, the destructive power that seed receives is little, percentage of damage reduces thereupon greatly, and the two ends of stiffener 2 are connected with connecting plate 1, a part for grizzly bar 3 is embedded in stiffener 2, can make guarantee working strength.
