Abstract
The utility model discloses an improved threshing concave plate which shows grid shape. Grid gap of feeding inlet end of the concave plate is smaller than the grid gap of the other parts, thus, when harvester operating, due to the smaller grid gap of the feeding inlet end, the grains and crops threshed are uneasy to pass the grid, which makes the crops threshed fully here, solving the problem of under threshing. Along with the grains moving towards an exhausting grass port, the grid gap of the exhausting grass port is larger, for more grains are gathering at exhausting grass port, therefore, the grains can pass the grid easily, and which makes the grains are uneasy to accumulate or outflow from the exhausting grass port. In order to ensure that the grains do not outflow with the stick and stem from the exhausting grass port, which causes entrainment loss, thus a leakage proof device which is an arc shape separator which is higher than grains layer is arranged at the exhausting grass port, with good separation of the grains and the stems, problem of grain entrainment loss solved, and the economic loss of the users reduced.
Description
Technical field
The utility model relates to a kind of threshing concave plate, relates in particular to a kind of threshing concave plate that is used for combine.
Background technology
Notch board is to finish the device that crop kernel separates with the stem stalk with the threshing cylinder combination of thresher, and the threshing of crop is clean and unclean, largely depends on the lattice structure of notch board, if the unclean problem of threshing appears in the grid excesssive gap of notch board so easily; If the grid gap of notch board is too small, excessive problem can appear carrying secretly so; At present, traditional notch board that domestic crawler type whole-feed rice combine uses, the gap of its grid is identical, can not well solve problems such as the excessive and threshing of entrainment loss is not clean when harvester operation.Cause in the process of using combine, wasted grain, and brought economic loss to the user.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of anti-loss and unclean improved threshing concave plate of threshing carried secretly.
For achieving the above object, the technical solution of the utility model is: improved threshing concave plate, described notch board is lattice-shaped, in the grid gap of the feeding mouth end of described notch board less than the grid gap of other parts.
As a kind of improvement, described notch board straw outlet near the feeding oral-lateral seed leak-proof device is installed;
As a kind of further improvement, described seed leak-proof device is one to be higher than the arc-shaped partition of seed layer.
Owing to adopt technique scheme, improved threshing concave plate, described notch board is lattice-shaped, in the grid gap of the feeding mouth end of described notch board less than the grid gap of other parts, so when harvester operation, because less in the grid gap of feeding mouth end, the seed of disengaging and stalk all are not easy to pass through grid, make crop compare sufficient threshing herein, solved the unclean problem of threshing; Along with seed moves to the straw outlet end, seed leaks down from the other parts of the bigger notch board in grid gap, is not easy accumulation or causes entrainment loss from the straw outlet outflow.In order to guarantee that further seed does not flow away from straw outlet with the bar stem, added leak-proof device at the straw outlet end, i.e. arc-shaped partition that is higher than the seed layer, make the seed that is lower than the seed layer height be blocked in feeding mouth one side of straw outlet, can not enter straw outlet, further solve the problem of seed entrainment loss, reduced economic loss of user.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the left view of Fig. 1.
Embodiment
As Fig. 1 or shown in Figure 2: improved threshing concave plate, described notch board is lattice-shaped, in the grid gap of feeding mouth 1 end of described notch board less than the grid gap of other parts, close feeding mouth 1 side at described notch board straw outlet 3 is equipped with the seed leak-proof device, described seed leak-proof device is an arc-shaped partition 2, and the height of this arc-shaped partition 2 should be greater than the thickness of the seed layer of setting.
Grain header is when operation, crop enters in the described notch board from the feeding mouth 1 of notch board, because little in the grid gap of feeding mouth 1 end, the seed of disengaging and stalk all are not easy to pass through grid, make crop compare sufficient threshing herein, solved the unclean problem of threshing; Along with seed moves to the straw outlet end, seed leaks down from the other parts of the bigger notch board in grid gap, is not easy accumulation or causes entrainment loss from straw outlet 3 outflows.In order to guarantee that further seed does not flow away from straw outlet with the bar stem, added leak-proof device at the straw outlet end, i.e. arc-shaped partition 2 that is higher than the seed layer, make the seed that is lower than the seed layer height be blocked in feeding mouth one side of straw outlet 3, can not enter straw outlet 3, further solve the problem of seed entrainment loss, reduced economic loss of user.
