Abstract
The utility model relates to a fan, air classification system and harvester should include the fan casing, and the fan casing is equipped with the air outlet, and air outlet department is equipped with can wobbling air regulation board. According to the actual conditions of grain maturity, the aperture of adjusting the air regulation board, the amount of wind of control air outlet, cereal grain seed that cause is disastrous because the grain maturity is different reaping the in -process can effectively to avoid the harvester, problem that the dirt percentage is high.
Description
Technical field
The utility model relates to a kind of blower fan, aidr bells blast system and harvester.
Background technology
The most a large amount of corn mowing machines used, put in place to disposably gather in, generally arrange aidr bells blast system in corn mowing machine, are used for the cereal grain seed in threshing chamber is carried out removal of impurities process.But during harvester is gathered in the crops, due to reasons such as weather, implantation time there are differences, the maturity of cereal has greatly difference, and the cereal grain seed quality in zones of different, weight are the most different.Existing harvester aidr bells blast system mainly utilizes the wind of air outlet blowout on Blower Housing to carry out selection by winnowing, owing to blower fan does not has air quantity regulatory function, air quantity regulation can not be carried out according to the actual conditions of different regions cereal grain seed from the air quantity of wind air outlet blowout, easily cause the loss of cereal grain seed big, the technical problem that percentage of impurity is high.
Utility model content
The purpose of this utility model is to provide a kind of blower fan, and the cereal grain seed caused owing to grain maturity is different in harvesting process in order to solve harvester loses big, the technical problem that percentage of impurity is high.A kind of aidr bells blast system using above-mentioned blower fan is provided it addition, the purpose of this utility model also resides in and uses the harvester of this aidr bells blast system.
A kind of blower fan of the present utility model adopts the following technical scheme that a kind of blower fan, and including Blower Housing, described Blower Housing is provided with air outlet, is provided with the air-flow plate that can swing at described air outlet.
Described blower fan also includes that rotating shaft, handle, described air-flow plate are fixedly connected in described rotating shaft, and described axis of rotation is connected on Blower Housing, and described handle is placed in the outside of Blower Housing and fixing with one end of described rotating shaft is connected.
Described handle is provided with for the retaining mechanism that its position is fixing.
Described retaining mechanism includes the connecting hole arranged on handle, is installed with bolt in connecting hole, and bolt is connected with nut, and described nut is uniformly fixedly connected on the outside of Blower Housing along the trend of connecting hole.
The novel a kind of aidr bells blast system of this enforcement adopts the following technical scheme that a kind of aidr bells blast system, and including blower fan, described blower fan includes that Blower Housing, described Blower Housing are provided with air outlet, is provided with the air-flow plate that can swing at described air outlet.
Described blower fan also includes that rotating shaft, handle, described air-flow plate are fixedly connected in described rotating shaft, and described axis of rotation is connected on Blower Housing, and described handle is placed in the outside of Blower Housing and fixing with one end of described rotating shaft is connected.
Described handle is provided with for the retaining mechanism that its position is fixing.
Described retaining mechanism includes the connecting hole arranged on handle, is installed with bolt in connecting hole, and bolt is connected with nut, and described nut is uniformly fixedly connected on the outside of Blower Housing along the trend of connecting hole.
A kind of harvester of the present utility model adopts the following technical scheme that a kind of harvester, and including aidr bells blast system, described aidr bells blast system includes above-mentioned blower fan.
The beneficial effects of the utility model: during grain harvest, actual conditions according to grain maturity, the aperture of the air-flow plate at regulation fan outlet, control the air quantity of air outlet, the cereal grain seed loss that harvester causes in harvesting process can be prevented effectively from owing to grain maturity is different big, the problem that percentage of impurity is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of a kind of blower fan of the present utility model.
Detailed description of the invention
The specific embodiment of a kind of blower fan of the present utility model, as shown in Figure 1, described blower fan includes the Blower Housing being provided with air outlet, being provided with air-flow plate 2 at air outlet, in embodiment, air-flow plate 2 is fixedly connected in rotating shaft 1, the two ends of rotating shaft 1 are rotatably connected on Blower Housing, drive the rotation of air-flow plate 2 for the ease of realizing rotating shaft 1, one end of rotating shaft connects has handle 3, handle 3 to be positioned at the outside of Blower Housing.
For the position of fixed handle 3, in embodiment, handle 3 is additionally provided with retaining mechanism, retaining mechanism is the connecting hole that handle 3 is provided with, being installed with bolt in connecting hole, bolt is connected with nut 4, coordinates the position by handle 3 to fix with nut 4 after passing, by bolt, the connecting hole that handle 3 is provided with.
In order to allow handle 3 can play indexing effect, reducing the used time of regulation air-flow plate 2, in embodiment, nut 4 is uniformly fixedly connected on the outside of Blower Housing, and the nut 4 position on Blower Housing is corresponding with the moving line of connecting hole.
Above-described embodiment is in use, actual conditions according to cereal, unclamp being connected of bolts and nuts 4, turning handle 3 regulation is positioned at the aperture of air-flow plate 2 at fan outlet, after the aperture of air-flow plate 2 has adjusted, bolt is utilized to pass the connecting hole of handle 3 one end and tighten the position of handle fixing with nut screw connection.
In other embodiments, air-flow plate can set threaded rotating shaft and be connected with two ends, connection handle can not be fixed in rotating shaft, axis of rotation is connected on Blower Housing, two ends are combined with nut, when regulating the aperture of air-flow plate regulation, directly push or pull on air-flow plate with hand and make to tighten the most afterwards at it nut at rotating shaft two ends.
