Description

Technical Field

[0001] The invention relates to the technical field of feeding equipment, and in particular to a quantitative automatic feeding method and device for underwater emergency power supply. Background Art

[0002] In the existing feeding operation technology field, the feeding method is mostly based on spiral feeding devices, and some of them are done manually. Although the spiral feeding can control the spiral speed and time to achieve quantitative feeding, its feeding accuracy is low and it is difficult to accurately control the feeding amount. In addition, the spiral feeding equipment has high precision requirements, resulting in high processing costs. Manual feeding requires the use of auxiliary weighing tools to achieve quantitative feeding, but manual feeding occupies high labor costs and has low efficiency, and cannot fundamentally realize automatic stirring and quantitative feeding operations.

[0003] Feeding devices are used in various industries, but most of the current underwater automatic feeding devices cannot achieve both good quantitative feeding and continuous effects. Therefore, the present invention provides a quantitative automatic feeding method and device for underwater emergency power supply to solve the above problems. Summary of the invention

[0004] In view of the problems existing in the prior art, the present invention provides a quantitative automatic feeding method and device for underwater emergency power supply with reasonable structural design.

[0005] In order to achieve the above technical purpose, the technical solution of the present invention is as follows: A quantitative automatic feeding device for underwater emergency power supply, characterized in that it includes a conical feeding box, a feeding device, a stepper motor and a feeding pipe with a valve. The stepper motor is connected to the feeding device through a motor shaft, which can drive the internal rotor of the feeding device to rotate synchronously. The stepper motor can realize automatic docking between the feeding bin of the feeding device rotor and the discharge port of the conical feeding box. The stepper motor is provided with an automatic limit device, which can realize automatic locking after the feeding device and the feeding pipe are docked, thereby completing the automatic feeding of the raw materials in the conical feeding box to the feeding pipe through the feeding device.

[0006] The feeding device comprises a stator, a rotor and a feeding bin arranged inside the rotor, the bottom of the feeding bin is provided with an openable end cover and a control device for adjusting the position of the end cover. The stator is the outer shell of the feeding device, and the central axis located at the center of the internal rotor is connected to the bearing at the center of the stator to ensure that the rotor can rotate coaxially in the stator, wherein the gap between the rotor and the inner wall of the stator is controlled to be 0.5-1mm.

[0007] As a further solution of the present invention, the stepper motor also includes a motor mounting cover connecting the motor and the feeding device, and the motor cover uses threaded holes and screws to connect the motor and the feeding device. The motor shaft is a wedge-shaped shaft and is connected to the wedge-shaped hole in the center of the rotor.

[0008] As a further solution of the present invention, a feeding valve is provided at the outlet of the feeding pipeline, and the feeding valve is used to control the opening and closing of the feeding outlet of the feeding pipeline.

[0009] As a further solution of the present invention, the rotor is a thick cylinder with a through hole on its curved surface as a feeding bin; an end cover is provided at the bottom of the feeding bin to seal the through hole to receive the raw materials; the open end of the feeding bin can be connected to the conical material box.

[0010] As a further solution of the present invention, the end cover can be opened downward to connect the two ends of the feeding bin for rapid feeding; the control device is arranged on the inner wall of the feeding bin, can adjust the depth of the end cover, and display the volume of the feeding bin on the system.

[0011] The quantitative automatic feeding method for underwater emergency power supply comprises the following steps: 1) Connect the stator of the feeding device to the discharge port of the conical material box through threads, and connect the rotor of the feeding device to the stepper motor through the motor shaft; 2) Start the stepper motor to make the rotor of the feeding device rotate smoothly. When the feeding bin of the feeding device rotor rotates and docks with the feeding port of the upper material box, the raw materials will be automatically loaded into the feeding bin by gravity; 3) The stepper motor drives the rotor of the feeding device to keep rotating in one direction. After the docking and feeding process, the feeding bin turns away from the material box in the middle and continues to turn to the feeding pipe below. When the feeding bin rotates to dock with the feeding pipe in the vertical direction of 120°, the stepper motor automatically limits and starts the feeding process; 4) After the stepper motor reaches the set position, the control valve opens automatically, and the raw materials fall through the 30° bend pipe horizontally downward under the action of gravity, completing the feeding action; 5) After one feeding action is completed, the stepper motor is controlled to continue rotating in the reverse direction. The feeding bin in the rotor of the feeding device will continue to add materials when passing through the middle position, and then automatically limit the position when docking with the feeding pipe on the other side to enter the next round of feeding work.

[0012] Compared with the existing invention, the beneficial effects of the present invention are: 1) The feeding device is fixed to the conical material box, and the motor can realize the automatic docking of the rotor of the feeding device and the discharge port of the conical material box, ensuring that the raw materials can be automatically loaded into the feeding device without external force; 2) The stepper motor can drive the rotor of the feeding device to perform alternating forward and reverse motion within the vertical range of ±120°. The rotor passes through the middle conical material box to pick up materials and reaches the feeding pipes on both sides to feed materials, thus meeting the continuous feeding process; 3) The bottom cover of the feeding bin on the rotor of the feeding device can be moved up and down to adjust the depth. The volume of the feeding bin can be adjusted according to the required feeding amount each time, and the quantitative feeding requirements can be achieved; 4) The feeding interval can be changed by adjusting the speed of the stepper motor; 5) When the raw materials need to be fed in at one time, the feeding bin can be rotated to the middle position to dock with the feeding port, and the bottom cover of the feeding bin can be opened to form a through hole inside the rotor. The raw materials can be directly fed from the conical feeding box into the feeding pipe below to achieve one-time rapid feeding.

[0013] 6) The automatic feeding device of the present invention can realize functions such as automatic docking, automatic feeding and automatic feeding, and can completely replace manual feeding to further improve efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The stepper motor 3 includes a motor mounting cover 301 connecting the motor 302 and the feeding device 2. The motor cover 301 has two sets of threaded holes, which are respectively connected to the motor 302 and the feeding device 2 using different screws.
