Embodiment
As shown in Figure 1, a kind of emitter controlling irregular grains of sand crevice projection angle and speed, comprise base 1, support 2, motor, control cantilever 5, brake rod 6, breaker slot 7, rotating disk 3, index dial, transmitting groove 4, rotating disk 3 center fixed rotating shaft, rotating shaft is supported by support 2, rotating shaft is rotated by driven by motor, rotating disk 3 has isometrical breaker slot 7, and the central angle of breaker slot 7 is 90 degree; Symmetrically arranged control cantilever 5 is socketed in rotating shaft, controls the both sides that spiral arm is arranged on support, and two control to connect brake rod 6 between spiral arm, and brake rod 6 passes perpendicularly through breaker slot; Have the space holding the grains of sand in rotating disk 3, be provided with emission port 41 in the edge of rotating disk 3, emission port 41 place is provided with and launches groove 4; Rotate counterclockwise, launch groove 4 diameter slightly larger than grains of sand maximum gauge, launch groove 4 axis and be arranged in the face of rotating disk and tangent with transmitting trench bottom central point place circle, therefore when disk is braked suddenly, the grains of sand can move away by the direction of transmitting groove; The face that brake rod contacts with breaker slot right side plan is positioned at the plane of symmetry of brake rod 6 perpendicular to rotating disk; Set the shooting angle that the angle controlling cantilever 5 just can control the grains of sand; Arrange switch, when brake rod 6 inserts opposite side, control lever 6 can press motor switch, motor power-off, ensures effect and the protection motor of braking; After lifting brake rod, manually press switching motor and again start.
Described transmitting groove 4 has gap at side roof part.
Described support 2 is ears bearing.
Described support 2 arranges index dial centered by the rotating shaft center of circle.
The speed reduction gearing 8 of twin shaft gears meshing is provided with between described motor and rotating shaft.
1., by the angular velocity of Electric Machine Control rotating disk, the distance according to launching the rotating shaft of fluted shaft line-spacing can calculate the speed of launching groove, and then draws the speed of launching the trench bottom grains of sand.
2. rotating disk such as orientation in Fig. 1 rotates counterclockwise, launch groove diameter slightly larger than grains of sand maximum gauge, launch fluted shaft line be arranged in the face of rotating disk and justify tangent with transmitting trench bottom central point place, therefore when disk is braked suddenly, the grains of sand can move away by the direction of launching groove.The face that brake rod contacts with breaker slot right side plan is positioned at the plane of symmetry of brake rod perpendicular to rotating disk.Set the shooting angle that the angle controlling cantilever just can control the grains of sand.
3. arrange switch, when brake rod inserts opposite side, control lever presses motor switch, motor power-off, ensures effect and the protection motor of braking.After lifting brake rod, manually pressing switching motor can start again.
4., because brake rod and rotating disk are hard brittle material, the collision that can produce between brake rod and rotating disk when pressing brake rod may make rotating disk to opposite direction resilience, also may damage brake rod.Therefore, at breaker slot end, need the materials such as rubber blanket are installed.
5. this device launches the angle between groove outlet and breaker slot end is fixing.
Using method: 1. calculate the control boom angle and the motor speed that make the grains of sand reach special angle and the setting of speed needs; 2. instrument is put into correct position, guarantee to stablize; 3. rotate and control cantilever, make the special angle on the tuning drive gear sensing index dial on control cantilever, fixing control cantilever, extracts control lever out; 4. by turntable rotation to making transmitting channel opening upwards, put into the grains of sand; 5. be energized, starter motor, arranges specific rotating speed; 6. to select a good opportunity after stabilization of speed insertion brake rod, power-off after machine is stable; 7. arrange instrument.
Embodiment described in the utility model does not form the restriction to the application's scope; within every spirit in the utility model design and principle, any amendment that one of skill in the art can make, equivalent to replace and improvement etc. all should be included within protection domain of the present utility model.
