Detailed implementation manners

[0020] The following further describes the detailed implementation manners of the present invention in conjunction with the accompanying drawings. It should be noted here that the description of these implementation manners is used to help understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various implementation manners of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] As shown in the figure, an intelligent and precise feeding and discharging device includes an outer shell 1, a knob switch 2, a motor 3, an auger rod 4, a first main board 6, and a second main board 7. Among them, the outer shell is a hollow structure formed by splicing a left outer shell 11 and a right outer shell 12. One end of the end of the outer shell is provided with a mounting port 13, and the other end is provided with a discharge port. The knob switch 2 is embedded and fixed in the mounting port 13 and partially protrudes from the mounting port 13. The surface of the knob switch 2 near the knob is provided with threads, and a nut is connected to the threads. The nut and the outer edge of the knob switch 2 form a connection position. The edge of the mounting port 13 is embedded in the connection position, and the nut can rotate on the threads. The nut can be connected to the outer shell near the mounting port 13, so as to play a role in fixing the knob switch 2. The side of the knob switch 2 away from the knob is fixed by the mounting bracket 14 inside the outer shell. A concave position for embedding the tail of the knob switch is provided on the fixing bracket, which can further play a role in fixing the knob switch 2 and prevent the entire switch from rotating at the installation part when the knob switch 2 rotates. In order to further strengthen the fixing effect, the mounting brackets 14 can be symmetrically arranged along the axial line of the outer shell. This setting can better avoid excessive pressure on one-sided mounting brackets 14. For the installation of the knob switch 2 in the present invention, both the axial and circumferential directions are fixed, which not only reduces the installation of additional fasteners and to a certain extent reduces the equipment production and assembly process, but also can better ensure the waterproof and dustproof performance of the equipment.

[0022] The first main board 6, the motor 3, the second main board 7, and the auger rod 4 are all fixed inside the housing and are sequentially connected along the axial direction of the housing. The second main board 7 is installed and fixed through the annular card slot 15. The side surface of the annular card slot 15 is connected to the inner surface of the housing. There are recesses on the annular card slot 15, and the second main board 7 is embedded in the recesses, and the second main board 7 is perpendicular to the axial line of the housing. Through the setting of the second main board 7, the feeding area corresponding to the auger rod 4 can be separated from the circuit area of the first main board 6, avoiding the feed and foreign objects in the feeding area from entering the circuit area and causing a short circuit, thus playing an effective role in waterproofing and dustproofing. In the present invention, the second main board 7 adopts a double-cut edge shape, which can make it fixed circumferentially after installation. This structure also reduces the installation of additional fasteners and ensures the waterproof and dustproof performance of the equipment. Of course, the description here only provides one installation form and does not limit that it must be installed in the structure of this form.

[0023] The motor 3 is a DC reduction motor. The motor 3 is located between the second main board 7 and the installation port 13 and is fixedly connected to the second main board 7. The rotation direction of the motor 3 passes through the second main board 7 and is connected to the auger rod 4. The auger rod 4 is a hollow structure, and there are raised locking points at the inner end, so that the rotating shaft of the motor 3 can be connected to the auger rod 4 in a snap-fit manner. The rotation of the rotating shaft of the motor 3 drives the auger rod 4 to rotate. Through this snap-fit installation form, the installation of additional fasteners can be reduced, and the equipment assembly process can be greatly reduced. At the same time, by rotating the auger rod 4 in the reverse direction, it can be removed from the DC reduction motor, achieving the purpose of being able to disassemble and assemble at any time, avoiding the cumbersome operation of having to disassemble the whole machine, and facilitating related operations such as later maintenance and debugging of the equipment. The auger rod 4 is provided with spiral blades in a spiral shape along its length direction, and the materials can be conveyed through the spiral blades.

[0024] Furthermore, in order to enhance the control of the accuracy of the conveyed materials, a plurality of circular grooves 41 are provided on the end surface of the auger rod 4 opposite to the second main board 7. The centers of the circular grooves 41 are evenly distributed on the same circumference. Magnets are fixed in the circular grooves 41, and the magnets are fixed through fasteners. Sensors are provided on the second main board. Through this structure, the working state information such as the rotation angle and rotation speed of the auger rod 4 of the feeding device can be monitored in real time, and it is also convenient to more precisely control the feeding amount of the feed through the control terminal. Of course, the specific number of the circular grooves 41 is not limited here, but it is at least 3. If more precise control is desired, the number of the circular grooves 41 can be appropriately increased, and the magnets located in the circular grooves 41 also need to be increased accordingly.

[0025] The first main board 6 is disposed opposite to the end of the knob switch 2, and at the same time, the first main board 6 is fixedly installed on the tail terminal of the DC reduction motor 3. The knob switch 2, the motor 3, and the sensor 8 are all electrically connected to the first main board 6. The first main board 6 collects the working state information such as the rotation angle and rotation speed of the auger rod 4 through the sensor 8, and at the same time controls the working state of the motor 3 according to the feedback or the setting of the program. In order to ensure the stable operation of the electronic devices and electronic components connected by each circuit, a plurality of heat dissipation holes 19 arranged side by side can be provided on the surfaces of the left housing 11 and the right housing 12 close to the mounting port 13.

[0026] An inlet is provided on the housing corresponding to the position of the auger rod 4 close to the second main board 7, and a feed pipe 16 is further provided on the inlet. The feed pipe 16 is in a horn shape, and this setting is beneficial to prevent the material from falling outside the feed pipe 16 when the material is poured. An outlet is provided at the other end of the housing opposite to the mounting port 13, and a discharge pipe 17 is also provided at the outlet. The discharge pipe 17 is a bent pipe, and the turning point thereof is close to the end of the auger rod 4. In this way, after the material passes through the auger rod 4, it can fall smoothly at the turning point, preventing the material from accumulating at the auger rod 4.

[0027] A marking area 18 is also provided on the housing. By scanning the code with a mobile device for the marking area 18, the first main board 6 can be controlled. The relevant configurations of the corresponding device can be modified and the relevant information of the corresponding device can be obtained, which is convenient for the operator to uniformly manage the equipment in the factory and effectively reduces problems such as the difficult debugging of equipment due to the large number of equipment. The setting of the marking area is beneficial for the staff to perform individual personalized customization on each feeding device in the breeding farm through the Internet of Things, greatly reducing the workload and realizing unmanned and intelligent feeding.

[0028] Furthermore, since the housing is composed of a left housing and a right housing spliced together, in order to facilitate splicing during disassembly, matching positioning grooves and positioning protrusions 121 can be provided in the middle part of the splicing contact surface position or the entire contact surface. In this embodiment, the positioning protrusions are provided at the contact surface close to the mounting port position, and the right housing is provided with positioning protrusions, while the left housing is provided with positioning grooves at the corresponding positions. During splicing, the positioning protrusions can be inserted into the positioning grooves. Of course, there is no limit that the positioning grooves must be on the right housing. They can be at various positions on the contact surface of one of the housings, and the other housing can be correspondingly provided with positioning grooves.

[0029] Through the above structural settings, the knob switch 2 is used to switch the working mode of the blanking device. According to the actual usage situation, the operator can adjust it to manual mode, automatic mode, and off state. The first main board 6 is used to control each component electrically connected to it to complete the specified work tasks. The second main board 7 is provided with sensors to form a detection circuit, detect the position of the magnet and send the signal to the first main board. At the same time, the second main board can isolate the auger rod 4 from the first main board 6 in real time, avoiding material splashing and foreign objects entering the area of the first main board 6, which may cause a short circuit in the circuit, thus ensuring the efficient, stable and safe operation of the equipment of the present invention. It should be noted that compared with other conveying forms, using the auger rod 4 for feed conveying has the characteristics of high stability, easy real-time adjustment of the conveying volume, and high output accuracy. The first main board is provided with an MCU, which can play the role of receiving signals and main control.

[0030] In summary, the intelligent and precise feeding blanking device disclosed in the embodiments of the present invention can switch the working mode of the intelligent feeding blanking device through the knob switch 2 to precisely control the amount of feed conveyed by the auger rod 4, making the conveying amount of the blanking device controllable and highly flexible, while greatly reducing the operation amount of the users.

[0031] The above has described in detail the embodiments of the present invention in conjunction with the drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present invention.
