Specific embodiment
As shown in figure 1, a kind of discharger that can control irregular grains of sand crevice projection angle and speed, including base 1, support
2nd, motor, control cantilever 5, brake bar 6, breaker slot 7, rotating disk 3, graduated disc, transmitting groove 4, rotating disk 3 center fixed rotating shaft, rotating shaft
Supported by support 2, rotating shaft is driven by motor and rotates, rotating disk 3 has isometrical breaker slot 7, the central angle of breaker slot 7 is 90 degree；
Symmetrically arranged control cantilever 5 is socketed in rotating shaft, controls spiral arm to be arranged on the both sides of support, two control connection braking between spiral arm
Bar 6, brake bar 6 passes perpendicularly through breaker slot；There is in rotating disk 3 space accommodating the grains of sand, be provided with emission port in the edge of rotating disk 3
41, it is provided with transmitting groove 4 at emission port 41；Rotate counterclockwise, transmitting groove 4 diameter is slightly larger than grains of sand maximum gauge, launches groove 4 axis
In the middle face of rotating disk and with transmitting trench bottom central point be located circle tangent, therefore when disk is braked suddenly the grains of sand can by send out
Move away in the direction penetrating groove；It is symmetrical perpendicular to rotating disk that the face that brake bar is contacted with breaker slot right side plan is located at brake bar 6
In face；Set the shooting angle controlling the angle of cantilever 5 just can control the grains of sand；Setting switch, brake bar 6 inserts opposite side
When, control bar 6 can press motor switch, motor power-off it is ensured that braking effect and protection motor；After lifting brake bar, handss
Dynamic press switching motor and be again started up.
Described transmitting groove 4 has gap in side roof part.
Described support 2 is ears bearing.
Graduated disc is arranged centered on the rotating shaft center of circle on described support 2.
It is provided with the speed reduction gearing 8 that twin shaft gear engages between described motor and rotating shaft.
1., by the angular velocity of motor control rotating disk, transmitting groove can be calculated according to the distance of transmitting fluted shaft line-spacing rotating shaft
Speed, and then draw the speed of the transmitting trench bottom grains of sand.
2. in rotating disk such as Fig. 1, orientation rotates counterclockwise, and transmitting groove diameter is slightly larger than grains of sand maximum gauge, launches fluted shaft line position
Being located in the middle face of rotating disk and with transmitting trench bottom central point, circle is tangent, and therefore when disk is braked suddenly, the grains of sand can be by transmitting
