Description

Device of discharge port mouth is used in a kind of husk rice

Technical field

The utility model relates to a kind of husk rice and uses device of discharge port mouth, belongs to the grain machinery technical field.

Background technology

In present rice process, paddy is processed into brown rice through hulling machine, and brown rice needs through abrasive type rice whitening machine or iron roll rice polisher the epidermis stone roller to be reamed again.Existing husk rice comprises discharging mouth group welding piece with device of discharge port mouth and is positioned at the pressure door of discharging mouth group welding piece throat that the center of pressure door is equipped with the pressure door bar.The precision of rice is by the control of the pressure door on the rice mill discharging mouth, and the pressure door aperture is more little, and the machine internal pressure of rice mill is big more, and then the precision of rice is high more; Otherwise the pressure door aperture is big more, and the machine internal pressure of rice mill is more little, and then the precision of rice is low more.At present the aperture size of pressure door sticks together and controls through large and small pressure is installed, and presses what that stick together to need artificial adjusting, and operative employee's experience is different with level, and the rice quality that the raw grain that may cause together batch processes has difference.

The utility model content

The purpose of the utility model is, overcomes the problem that exists in the prior art, provides a kind of husk rice to use device of discharge port mouth, can realize the accurate control of pressure door aperture.

For solving above technical problem; Device of discharge port mouth is used in a kind of husk rice that the utility model provided; Comprise discharging mouth group welding piece and be positioned at the pressure door of discharging mouth group welding piece throat, the center of said pressure door is equipped with the pressure door bar, also comprises stepper motor, link, Connection Block and T type screw rod; The output shaft of said stepper motor, T type screw rod and said pressure door bar coaxial line; Said stepper motor is fixed on the said link, and said link is fixed on the said Connection Block, and said Connection Block is fixed on the outer wall of said discharging mouth group welding piece; Said T type screw rod is arranged in said Connection Block and axially limited, and stretch out from Connection Block at the two ends of T type screw rod, and its rear end is fixedly connected with the output shaft of said stepper motor, and front end spins through the rear end of screw thread and said pressure door bar.

With respect to prior art; The utility model has been obtained following beneficial effect: stepper motor drives T type screw rod and rotates under the control of control system; Because T type screw axial is limited; Therefore drive the pressure door bar when T type screw rod rotates and move axially, and then the pulling pressure door moves axially, realize that the aperture of pressure door is regulated.

Improvement as the utility model; Said pressure door is sleeved on the front end of said pressure door bar through self centre bore; Be set with spring on the said pressure door bar, said spring one end is supported on the rear end face of said pressure door, and the other end is supported on the inwall of said discharging mouth group welding piece.When the pressure door external pressure is suitable with rice machine internal pressure, reach stable state, do not need moving of step motor control pressure door bar this moment, the flexible variation among a small circle that can compensate the rice mill internal pressure of spring.

Fig. 4 is the stereogram of Fig. 1.

Among the figure: 1. stepper motor, 2. link, 3.T type screw rod, 4. Connection Block, 5. discharging mouth group welding piece, 6. the pressure door bar, 7. spring, 8. pressure door, 9. stop screw, 10. tablet, 11. is near switch.

The specific embodiment

To shown in Figure 4, device of discharge port mouth is used in the husk rice of the utility model like Fig. 1, comprises discharging mouth group welding piece 5 and is positioned at the pressure door 8 of discharging mouth group welding piece throat; Also comprise stepper motor 1, link 2, Connection Block 4 and T type screw rod 3; The center of pressure door 8 is equipped with pressure door bar 6, the output shaft of stepper motor 1, T type screw rod 3 and pressure door bar 6 coaxial lines, and stepper motor 1 is fixed on the link 2; Link 2 is fixed on the Connection Block 4, and Connection Block 4 is fixed on the outer wall of discharging mouth group welding piece 5.T type screw rod 3 is arranged in Connection Block 4 and axially limited, and stretch out from Connection Block 4 at the two ends of T type screw rod 3, and its rear end is fixedly connected with the output shaft of stepper motor 1, and front end spins through the rear end of screw thread and pressure door bar 6.The back side of pressure door is equipped with signal lever; The rear end of signal lever is equipped with tablet 10; Two extreme positions of pressure door are separately installed with near switch 11, and the extreme position of the minimum aperture of pressure door also is equipped with stop screw 9, guarantee the normal operation of stepper motor 1 near switch 11 with tablet 10, stop screw 9; When detecting tablet 10 near switch 11 and reach the limit of the position, the control system will cut off the power supply of stepper motor 1.

In the work; Stepper motor 1 drives down T type screw rod 3 in the control of control system and rotates because T type screw axial is limited, so T type screw rod 3 when rotating drive pressure door bar 6 move axially; And then pulling pressure door 8 moves axially the aperture adjusting of realization pressure door 8.

Pressure door 8 can be fixedly connected with pressure door bar 6; Also can be sleeved on the front end of pressure door bar 6 through the centre bore of self, at this moment, be set with spring 7 on the pressure door bar 6; Spring 7 one ends are supported on the rear end face of pressure door 8, and the other end is supported on the inwall of discharging mouth group welding piece 5.When pressure door bar 6 forwards stretched out, spring promoted pressure door 8 and moves forward; When the pressure door external pressure is suitable with rice machine internal pressure, reach stable state; Do not need moving of stepper motor 1 controlled pressure door bar 6 this moment; When pressure door 8 runs into moment during bigger machine internal pressure, pressure door 8 will promote spring 7 compressions, return to original position subsequently.

Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
