Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, and more specifically relates to an intelligent feeding platform lifting mechanism and its device. Background Technology

[0002] Feeding is one of the key aspects of aquaculture. Feeding meets the nutritional needs of aquatic animals, and proper feeding can provide them with various nutrients necessary for growth, including protein, fat, carbohydrates, vitamins, and minerals. This helps promote the growth and development of aquatic animals, improve the yield and quality of aquaculture, and maintain a good water quality environment.

[0003] Currently, most feeding platforms are used for feeding. By lifting and observing the remaining feed in the platform, the feeding status of the shrimp can be obtained, and the amount of feed can be effectively adjusted to prevent overfeeding or underfeeding. However, during operation, existing equipment is prone to misjudging whether the feeding platform has been lowered to the predetermined position, which can lead to incorrect information for the farmers and economic losses. Therefore, there is an urgent need for an intelligent feeding platform lifting mechanism that can solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide an intelligent feeding platform lifting mechanism and device, which can accurately place the feeding platform as needed to ensure accurate feeding and thus facilitate effective adjustment of feed feeding amount.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A smart material platform lifting mechanism includes a winding assembly, a take-up box, and a sensing assembly. The winding assembly includes a motor, a take-up reel located at the motor output end, and a feeding platform. A traction rope is wound around the take-up reel, and the other end of the traction rope is connected to the top of the feeding platform. The feeding platform includes a base plate, a fixing ring located on the base plate, and a side plate located between the base plate and the fixing ring. The take-up box includes a left housing and a right housing that can be interlocked. The left housing has a mounting post for mounting a steering wheel. The sensing assembly includes a Hall sensor located in the right housing and an encoder magnetic ring fitted on the end of the steering wheel near the Hall sensor. The Hall sensor and the steering wheel are correspondingly arranged.

[0007] According to a first aspect of the present invention, the left housing is provided with a first mounting groove and a second mounting groove for accommodating the take-up reel, and an opening is provided between the first mounting groove and the second mounting groove for one end of the traction rope to pass through.

[0008] According to a first aspect of the present invention, the inner diameter of the second mounting groove is less than or equal to the outer diameter of the take-up reel, and the gap between the contour of the second mounting groove and the maximum contour of the take-up reel is less than the diameter of the traction rope.

[0009] According to a first aspect of the present invention, the left housing is further provided with a guide groove for the extension of the traction rope connection end, the guide groove is connected to the first mounting groove, and the first mounting groove is connected to the second mounting groove through the opening.

[0010] According to a first aspect of the present invention, a spring-loaded component and a positioning component capable of pressing against the spring-loaded component are installed in the guide groove. One end of the traction rope passes through the spring-loaded component and the positioning component and is connected to the feeding platform. A position sensor is provided on one side of the guide groove. The position sensor is used to detect the position of the positioning component to control the working state of the motor.

[0011] According to a first aspect of the present invention, the diameter of the base plate is smaller than the diameter of the fixing ring.

[0012] According to a second aspect of the present invention, an intelligent material platform device further includes a floating device, the floating device including a floating frame, a suspension ball respectively disposed at each support of the floating frame, and a bottom protective plate, wherein the sensing component is located above the bottom protective plate.

[0013] According to a second aspect of the present invention, the bottom protective plate is provided with a through hole through which the traction line can pass, and a cover is provided above the bottom protective plate, and the sensing component is located in the cavity formed by the bottom protective plate and the cover.

[0014] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:

[0015] This invention features an encoder magnetic ring mounted on the idler wheel near the Hall sensor, aligning the Hall sensor with the idler wheel. When the motor is started, the traction rope, under the weight of the feeding platform, drives the idler wheel and encoder magnetic ring to rotate. As the feeding platform rises, the traction rope drives the idler wheel and encoder magnetic ring to rotate in the opposite direction. The Hall sensor can then determine the state of the encoder magnetic ring, indicating whether the idler wheel is rotating and in the forward or reverse direction. This allows the operator to accurately determine whether the feeding platform is in the rising, falling, or hovering phase, enabling precise judgment of the platform's position and accurate feeding status. This facilitates timely and effective adjustments to the feed amount. Attached Figure Description

[0028] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0029] See attached document Figure 1 To be continued Figure 6 As shown, an intelligent material platform lifting mechanism and its device include a lifting device 1, a winding assembly 2 disposed on the top of the lifting device 1, a sensing assembly, a limiting mounting assembly, and a central control assembly 7 electrically connected to each assembly.

[0030] In one embodiment of the present invention, the buoyancy device 1 includes a floating frame 11, a suspension ball 12 respectively provided at each support of the floating frame 11, a bottom guard plate 13, and a cover 14 provided on the bottom guard plate 13. The bottom guard plate 13 is provided with a through hole through which the traction rope 24 can pass, and the through hole corresponds to the outlet of the guide groove 6.

[0031] In one embodiment of the present invention, the winding assembly 2 includes a motor 21, a take-up reel 22 disposed at the output end of the motor 21, and a feeding platform located below the floating frame 11. A traction rope 24 is wound on the take-up reel 22, and the other end of the traction rope 24 is connected to the top of the feeding platform.

[0032] In one embodiment of this utility model, the feeding platform includes a base plate 231 made of mesh material, a fixing ring 232 disposed on the base plate 231, and a side plate 233 made of mesh material disposed between the base plate 231 and the fixing ring 232. The diameter of the base plate 231 is smaller than the diameter of the fixing ring 232, so that the base plate 231, the fixing ring 232 and the side plate 233 form a bowl shape, thereby effectively preventing feed spillage during the up-and-down floating process of the feeding platform.

[0033] In one embodiment of this utility model, the sensing component includes a Hall sensor disposed within the right housing 412 and an encoder magnetic ring 32 sleeved on the end of the idler wheel 31 near the Hall sensor. The Hall sensor and the idler wheel 31 are correspondingly arranged. The encoder magnetic ring 32 has thirteen pole pairs. The Hall sensor includes a PCB board and two Hall elements spaced apart on the PCB board. Thus, when the feeding platform moves up and down, the traction rope 24 will drive the idler wheel 31 to rotate in the forward or reverse direction. When the pole pairs on the encoder magnetic ring 32 pass through the two Hall elements spaced apart on the PCB board, the rotation direction of the idler wheel 31 can be determined, thereby determining whether the feeding platform is in the upward or downward movement stage. When the two Hall elements spaced apart on the PCB board cannot detect the passage of the pole pairs on the encoder magnetic ring 32, the feeding platform is in a suspended state. Thus, the operator can accurately determine the position of the feeding platform, thereby obtaining accurate feeding information and facilitating timely and effective adjustment of the feed amount.

[0034] In one embodiment of the present invention, the limiting installation component includes a take-up box 41, which includes a left housing 411 and a right housing 412 that can be interlocked. The left housing 411 is provided with a first mounting groove and a second mounting groove for accommodating the take-up reel 22. An opening 5 is provided between the first mounting groove and the second mounting groove for one end of the traction rope 24 to pass through.

[0035] In one embodiment of this utility model, an opening 5 is provided between the first mounting groove and the second mounting groove for one end of the traction rope 24 to pass through. A guide groove 6 is provided inside the left housing 411 for the connecting end of the traction rope 24 to extend out. The guide groove 6 is connected to the first mounting groove. The first mounting groove and the second mounting groove are connected through the opening 5. A through hole is provided on the bottom guard plate 13 for the traction rope 24 to pass through, so that the traction rope 24 can drive the idler wheel 31 to rotate by lowering the feeding platform.

[0036] In one embodiment of this utility model, the inner diameter of the mounting hole of the idler wheel 31 is larger than the outer diameter of the mounting column, and an arc-shaped boss 8 is provided at the opening 5. When the motor 21 is working, the feeding platform descends. Under the gravity of the feeding platform, the idler wheel 31 can be rotated by the traction rope 24. The arc-shaped boss 8 avoids interfering with the rotation of the idler wheel 31.

[0037] In one embodiment of this utility model, the inner diameter of the second mounting groove is set to be less than or equal to the outer diameter of the take-up reel 22, and the gap between the outline of the second mounting groove and the maximum outline of the take-up reel 22 is less than the diameter of the traction rope 24. Thus, the connecting end of the traction rope 24 can pass through the opening 5, the guide groove 6, and the through hole in sequence and connect to the feeding platform. Then, the traction rope 24 can drive the idler wheel 31 to rotate by lowering the feeding platform, and the Hall sensor records the action of the idler wheel 31.

[0038] In one embodiment of this utility model, a pin is provided on the top of the feeding platform, and a spring-loaded component and a positioning component that can press against the spring-loaded component are installed in the guide groove 6. A magnet is provided inside the positioning component. One end of the traction rope 24 passes through the spring-loaded component and the positioning component and is connected to the feeding platform. The guide groove 6 is located in the left housing 411. A position sensor is provided on one side of the guide groove 6. The position sensor is a Hall sensor and is connected to the motor 21. When the feeding platform rises to the highest position, the pin will press against the positioning component and move it upward. Then, the position sensor can determine the position of the feeding platform by sensing the position of the magnet inside the positioning component, and then control the working state of the motor 21.

[0039] When the feeding platform descends, the spring-loaded component is in an extended state, and the push-position component is always at the bottom of the guide groove 6. When the feeding platform rises to the maximum distance, the push-position component will compress the spring-loaded component to move its position upward. At this time, the position sensor on one side can detect the position change of the component in time through the magnet, thereby controlling the motor 21 to stop working.

[0040] In one embodiment of this utility model, the method for lifting control via the intelligent material platform lifting mechanism and device includes the following steps:

[0041] 1. Start motor 21, the feeding platform descends, and under the action of gravity and friction, the traction rope 24 will drive the idler wheel 31 and the encoder magnetic ring 32 to rotate. Reverse motor 21, the feeding platform rises, and the traction rope 24 will drive the idler wheel 31 and the encoder magnetic ring 32 to rotate in the opposite direction.

[0042] 2. When the pole pairs set on the encoder magnetic ring 32 pass through the two Hall elements set at intervals on the PCB board, the rotation direction of the idler wheel 31 can be determined, thereby determining whether the feeding platform is in the upward or downward movement stage.

[0043] 3. When the two Hall elements spaced apart on the PCB fail to detect the passing of the upper pole pair of the encoder magnetic ring 32, the feeding platform is in a hovering state.

[0044] In one embodiment of this utility model, when determining whether the feeding platform has reached the top, it can be determined whether the current is continuously high. That is, after maintaining a high current for a period of time, it can be ensured that the feeding platform reaches the highest point. At this time, the motor 21 stops working and pulls the feeding platform to avoid burning out the machine.

[0045] This intelligent feeding platform lifting mechanism and device uses an encoder magnetic ring 32 installed at the end of the idler wheel 31 near the Hall sensor to correspond the Hall sensor to the idler wheel 31. When the motor 21 is started, the traction rope 24 will drive the idler wheel 31 and the encoder magnetic ring 32 to rotate under the gravity of the feeding platform. When the feeding platform rises, the traction rope 24 will drive the idler wheel 31 and the encoder magnetic ring 32 to rotate in the opposite direction. The Hall sensor can then determine whether the idler wheel 31 is rotating and whether the rotation direction is forward or reverse, so as to determine whether the feeding platform is in the rising stage, the falling stage, or the hovering state. In this way, the operator can accurately determine the position of the feeding platform and obtain accurate feeding information, which can facilitate timely and effective adjustment of the feed amount.

[0046] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
