Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of feeding soft granular feed to giant salamanders, in particular to a giant salamander precision feeding and material preparation system and method based on supply and demand linkage. BACKGROUND

[0002] In giant salamander breeding, soft granular feed is widely used due to its suitability for the digestive characteristics of giant salamanders. The feed prepared by the granulator is temporarily stored in a low-temperature storage bin. When feeding is needed, the feed in the low-temperature storage bin is distributed to each pool through an intelligent feeding assembly. However, such feed has high water content and high viscosity, making storage and discharge difficult.

[0003] Existing feed storage bins are mostly single funnel type, which is suitable for hard granular feed but exposes fatal defects when used for soft granular feed, seriously affecting breeding efficiency and the health of giant salamanders.

[0004] Firstly, it is easy to form a "bridge" structure between the particles and the wall under the pressure of gravity, directly blocking the discharge port, causing the driving mechanism to idle, affecting feeding, and possibly damaging equipment and increasing costs. Even if a vibration mechanism is installed outside the storage bin, the vibration will accelerate the compaction of the feed, further exacerbating the blockage.

[0005] Secondly, the feed is prone to accumulation and deterioration. The shelf life of soft granular feed is only 1-2 days, and the "top-down" discharge method of the funnel-type bin will cause the old feed at the bottom to be continuously accumulated and not discharged in time, eventually causing mold and deterioration. Giant salamanders are prone to illness and even death after eating, causing economic losses.

[0006] Therefore, the present application designs a giant salamander precision feeding and material preparation system and method based on supply and demand linkage to solve the above problems. SUMMARY

[0038] Please see Figures 1-12 This invention provides a technical solution: a precision feeding and feed preparation system for giant salamanders based on demand-supply linkage, including a feed pellet mill 101 (used to pellet fish paste or various mixed powder raw materials), a low-temperature storage chamber 1 (the low-temperature storage chamber 1 is a chamber with low-temperature preservation function), and an intelligent feeding component 2. It also includes an intelligent control system, which consists of a video monitoring system and a control center (common knowledge to those skilled in the art, and will not be described in detail or shown in the figures here). The video monitoring system is installed above each breeding pond to monitor the swimming and feeding status of the giant salamanders in real time, and to mark and identify each giant salamander. Based on the monitoring data, combined with the growth stage and past feeding patterns of the giant salamanders, the control center calculates the feeding requirements of each pond and then calculates the amount of feed required for each feeding. The intelligent feeding component 2 responds to the instructions of the control center, obtains a set weight of feed from the low-temperature storage chamber 1, and delivers it to the target breeding pond as needed.

[0039] The intelligent feeding assembly 2 comprises a transfer metering hopper 201 and an intelligent feeding machine 202 for dispensing the feed and feeding (both the transfer metering hopper 201 and the intelligent feeding machine 202 are well known to those skilled in the art and will not be described in detail here);

[0040] The low-temperature storage bin 1 is internally provided with a receiving assembly and a layered vibration discharging assembly. The layered vibration discharging assembly comprises a plurality of discharging units vertically distributed inside the low-temperature storage bin 1, which replaces the traditional single-hopper structure. The discharging unit comprises a receiving table 3, a movable material frame 4, a driving mechanism, and a receiving assembly. The top and side wall of the movable material frame 4 are closed, and the bottom is open. The receiving table 3 is fixedly arranged on the inner wall of the low-temperature storage bin 1, and the bottom of the movable material frame 4 is open and attached to the top end of the receiving table 3, with the side wall being closed. The movable material frame 4 can move horizontally along the surface of the receiving table 3 under the driving of the driving mechanism, so as to push the feed from the end to the intelligent feeding assembly 2 below. The driving mechanism not only provides horizontal driving force, but also integrates a vibration function. In the process of driving the movable material frame 4 to move horizontally, the receiving table 3 and the movable material frame 4 are simultaneously subjected to high-frequency micro-amplitude vibration. The receiving assembly comprises a flow guide pipe 5 and a guide mechanism. The guide mechanism is used to move the flow guide pipe 5 to the side corresponding to each movable material frame 4, and then add the finished feed to the inside of the movable material frame 4.

[0041] The guide mechanism comprises a first screw rod 6 rotatably arranged on the low-temperature storage bin 1 and a closing plate 7 rotatably connected with the inner wall of the movable material frame 4. The first screw rod 6 is threadedly connected with the flow guide pipe 5. The closing plate 7 is rotatably connected with the movable material frame 4. A push rod 8 is slidably connected with the side wall of the flow guide pipe 5, and a spring one 801 is fixedly arranged between the push rod 8 and the side wall of the flow guide pipe 5. When the push rod 8 moves to contact the closing plate 7, the closing plate 7 is pushed from the normally closed state to the open state.

[0042] A gear one 701 is fixedly arranged on the rotating shaft of the closing plate 7. The gear one 701 is engaged with a gear two 702, which is rotatably connected with the inner wall of the movable material frame 4. A torsional spring one 705 is sleeved on the rotating shaft of the gear two 702. The gear two 702 is fixedly arranged with a rotating rod 703, which is rotatably connected with the inner wall of the movable material frame 4. A push plate 704 is slidably arranged at the bottom end of the rotating rod 703 and is slidably connected with the inner wall of the movable material frame 4. When the closing plate 7 changes from the normally closed state to the open state, the gear one 701 is engaged with the gear two 702, and the accumulated feed is leveled by the push plate 704 driven by the rotating rod 703.

[0043] As shown in Figures 1-12 ,

[0044] The feeding process of the movable material frame 4 (as shown in Figure 5 , Figures 9-12 ) is as follows:

[0045] The pelleted soft feed enters the guide tube 5 through the corrugated pipe 501. Then, the first screw 6 rotates, causing the guide tube 5 to move from bottom to top to the corresponding side of each movable feed frame 4. When the push rod 8 has not moved to the position corresponding to the closing plate 7, the side wall of the movable feed frame 4 blocks the push rod 8, keeping the spring 801 in a compressed state. When the push rod 8 moves to the position corresponding to the closing plate 7 (as shown in the image), the push rod 8 moves to the position corresponding to the closing plate 7 (as shown in the image). Figure 11 and Figure 12 As shown), the elastic release of spring 801 pushes the closing plate 7 to rotate into the movable material frame 4 through push rod 8. The closing plate 7 drives gear 702 to rotate through gear 701, thereby compressing torsion spring 705. Meanwhile, the rotating rod 703 rotates along the dial plate 704 towards the closing plate 7 and drives the dial plate 704 to move synchronously.

[0046] Then the pellet mill 101 discharges the feed produced inside into the movable feed frame 4. After the discharge is completed, the guide pipe 5 or the pellet mill 101 first stops discharging, and then the first screw 6 continues to rotate and lifts the guide pipe 5 to one side of the middle movable feed frame 4 to continue discharging. Then the upper movable feed frame 4 is discharged.

[0047] After the push rod 8 disengages from the closing plate 7, the torsion spring 705 drives the rotating rod 703 to reset, while the lever 704 moves to the right to the initial position and smooths out the feed piled up on the side near the closing plate 7 to the right to avoid compaction, which facilitates subsequent vibration discharge.

[0048] Discharge process:

[0049] The drive mechanism first drives the bottommost movable material frame 4. Figure 5 The material feeding channel, located directly above the material receiving platform 3, slowly moves horizontally to the right, and the right side wall of the movable material frame 4 changes from a closed state to an open state with the right end of the material receiving platform 3 (as shown). Figure 7 As shown in point a), during the movement, the left side wall of the movable feed frame 4 pushes the material at the top of the receiving platform 3 to the right, and the receiving platform 3 and the movable feed frame 4 generate high-frequency micro-amplitude vibration. The vibration breaks the adhesion between the soft granular feed particles, and the horizontal thrust forces the material to be discharged, avoiding the clogging problem caused by gravity compaction in the traditional funnel structure.

[0050] The feed falling from the feeding channel gradually falls into the inside of the transfer metering hopper 201 through the V-shaped collecting hopper 203, the transfer metering hopper 201 is provided with a weight detection module and a valve that is opened when triggered (both belong to the common knowledge of those skilled in the art and existing technology) for real-time monitoring of the amount of falling feed, the valve remains closed before the amount of falling feed reaches the required amount of feed for multiple breeding pools, when the amount of falling feed reaches the required amount, the driving mechanism stops driving the movable material frame 4 and drives the movable material frame 4 to reset to the initial position; then the valve opens to make the feed in the inside of the transfer metering hopper 201 fall into the inside of the intelligent feeder 202, and the intelligent feeder 202 distributes the feed to the inside of multiple breeding pools.

[0051] If the lower movable material frame 4 is completely moved to the rightmost side, i.e. the feed stored on the lower material supporting table 3 does not reach the total requirement, the transfer metering hopper 201 does not detect a change in weight, and the lower movable material frame 4 is reset to the initial position, then the middle movable material frame 4 is driven to the right until the required amount is reached.

[0052] The present application realizes synchronization of vibration and discharge by layered vibration and discharge, generates continuous and moderate vibration of the material supporting table 3 and the movable material frame 4, and the vibration mode is different from the traditional external vibration mechanism, which does not speed up the compaction of the feed, but can destroy the adhesion between soft pellet feed, improve the flowability of the feed, avoid the formation of arch structure from the root, avoid the problem of blockage, and ensure smooth discharge.

[0053] The multi-layer vertically distributed discharge unit realizes layered storage of the feed, cooperates with the logic of bottom priority discharge and upper layer replenishment, avoids the long-term accumulation of bottom feed caused by the "from top to bottom" discharge of the traditional funnel type bin from the structure; the closed structure of the movable material frame 4 reduces the excessive contact of the feed with cold air, cooperates with the fresh keeping function of the low-temperature storage bin 1, further prolongs the fresh period of the feed, adapts to the short shelf life requirement of 1-2 days of soft pellet feed, avoids the influence of feed mildewing and deterioration on the health of giant salamanders, at the same time, the flattening effect of the push plate 704 and the end cleaning effect of the warped plate 301 in the material receiving assembly ensure uniform distribution of the feed without local accumulation, further improving the freshness of the feed used; the design of the structure of the movable material frame 4 "top and side wall closed, bottom open" not only prevents feed leakage, but also avoids moisture loss and hardening of the feed, and adapts to the demand of giant salamanders for soft and cohesive feed.

[0054] The intelligent control system combines the swimming and feeding data of giant salamanders obtained through video monitoring to accurately calculate the feeding amount, realizes the demand-supply linkage of "on-demand feed preparation-accurate storage-quantitative feeding", avoids feed waste, reduces breeding cost, and the accurate feeding can adapt to the feeding characteristics of giant salamanders, improve their growth state and artificial labor efficiency.

[0055] The driving mechanism includes a vibration unit and a linear drive unit:

[0056] The linear drive unit includes a second lead screw 9, which is rotatably mounted on the inner wall of the low-temperature storage chamber 1. A drive component 901 is threaded onto the second lead screw 9 and is slidably connected to the inner wall of the low-temperature storage chamber 1. The drive component 901 is used to drive the movable material frame 4 to move.

[0057] The vibration unit includes a drive block 10, several protrusions 1001 distributed along the length of the support platform 3, and a fixing plate 1002 located below the support platform 3. The fixing plate 1002 is slidably connected to the support platform 3. The drive block 10 is elastically rotatably mounted on the drive member 901 and the drive block 10 can only rotate in the reset direction of the movable material frame 4.

[0058] A limiting rod 902 is provided on one side of the driving component 901. The limiting rod 902 is elastically slidably connected to the inner wall of the low temperature storage chamber 1 through a return spring 905. The driving component 901 is used to push the limiting rod 902 to move. The limiting rod 902 is slidably connected to the side wall of the movable material frame 4.

[0059] like Figures 2-4 as well as Figure 6 As shown:

[0060] There is a certain distance between the driving component 901 and the limiting rod 902. When the second lead screw 9 (both the first lead screw 6 and the second lead screw 9 are driven by a motor) rotates, it drives the driving component 901 to slide to the right on the guide rod 903 set on the inner wall of the low-temperature storage chamber 1, thereby driving the movable material frame 4 to move and discharge material. When the driving component 901 moves to contact the contact component 302, it will push the contact component 302 to rotate to the right around the rotation axis and rotate to make way under the driving component 901 (e.g., Figure 6 As shown in the figure, for ease of understanding, the part where the driving member 901 contacts the contact member 302 is shown in the figure. Figure 4 The lower pressing edge 904 is marked as shown;

[0061] Before contacting the limiting rod 902, the drive block 10 will first contact the protrusion 1001 on the side near the protrusion 1101 and push the material receiving platform 3 upward (the drive block 10 cannot rotate due to the obstruction of the side wall of the drive component 901 during discharge). After passing the protrusion 1001, it will vibrate, which will pre-vibrate the feed before the movable material frame 4 moves, thus breaking the adhesion of the feed. When the drive component 901 moves a distance L to the right, it will contact the limiting rod 902 and drive the limiting rod 902 and the movable material frame 4 to move synchronously for discharge. During this process, the material receiving platform 3 and the movable material frame 4 will both rise relative to the fixed plate 1002 while vibrating, and the movable material frame 4 will slide repeatedly along the limiting rod 902, thus vibrating while discharging.

[0062] After the discharging is completed, the feed is pushed by the movable material frame 4 to the right side of the material receiving table 3 close to the discharging channel (i.e. the position of point a), and forms a pile, at this time the second lead screw 9 is reversely rotated, and the driving part 901 is reset to the initial position by the elastic reset of the reset spring 905, in this process, the driving block one 10 is blocked by the protrusion one 1001 and rotates to the right and compresses the torsion spring two 1003, and will not continue to vibrate, so as to prevent the vibration from causing the feed piled on the right side to fall due to vibration when the movable material frame 4 is not reset to the initial position (i.e. the discharging channel a is closed), resulting in the problem of increased feed amount.

[0063] The side of the driving block one 10 away from the protrusion one 1001 is provided with a driving block two 11, the driving block two 11 is rotationally arranged on the driving part 901, the rotation shaft sleeve of the driving block two 11 is provided with a torsion spring three 1102, a plurality of protrusions two 1101 are arranged above the driving block two 11, the top end height of the driving block two 11 is lower than that of the protrusion one 1001, and the bottom height of the protrusion two 1101 is lower than that of the protrusion one 1001.

[0064] As shown in Figure 3 , Figure 4 and Figure 6 ,

[0065] When discharging (the movable material frame 4 moves to the right), and before the driving part 901 contacts the limiting rod 902, the driving block two 11 moves to the right and compresses the torsion spring three 1102 when contacting the protrusion two 1101, and the top end of the driving block two 11 is lower than the bottom end of the protrusion one 1001 and will not contact during the whole discharging process;

[0066] When the discharging is completed and the movable material frame 4 is reset to the initial position by the reset spring 905, the driving part 901 gradually moves away from the limiting rod 902, at this time the driving block two 11 moves to contact the protrusion two 1101, then the material receiving table 3 is lifted and vibrated to reduce the height of the feed piled on the right side of the material receiving table 3 under the action of vibration, thereby avoiding compaction.

[0067] The material receiving table 3 is rotationally connected with a flap 301, the rotation shaft of the flap 301 is located between the driving part 901 and the limiting rod 902 and is away from both the driving part 901 and the limiting rod 902, the rotation shaft of the flap 301 is rotationally arranged outside with a contact part 302, the rotation shaft sleeve of the contact part 302 is provided with a torsion spring four 303, and the contact part 302 can only rotate when the movable material frame 4 is pushing material; when the driving part 901 is about to reset to the initial state, it will contact the contact part 302 and forcibly drive the flap 301 to rotate, so that the feed particles piled at the end are flowed to one side through the rotation of the flap 301 when the movable material frame 4 is pushing material.

[0068] As shown in Figure 8 ​

[0069] When the movable material frame 4 is reset, the lower pressing edge 904 will contact the contact piece 302 after the movable material frame 4 is reset to the initial position and before the driving member 901 is reset to the initial position, but the contact piece 302 cannot rotate around the rotating shaft at this time, so it forcibly drives the flap 301 to rotate inside the movable material frame 4 and on the material supporting table 3, and then the right side accumulated feed body (identified as A1 in the middle) flows to the left under the lifting of the flap 301, is evenly distributed, and is reduced and compacted under the auxiliary action of the vibration generated by the second driving block 11 and the second protrusion 1101. Figure 7 When the movable material frame 4 is reset, the lower pressing edge 904 will contact the contact piece 302 after the movable material frame 4 is reset to the initial position and before the driving member 901 is reset to the initial position, but the contact piece 302 cannot rotate around the rotating shaft at this time, so it forcibly drives the flap 301 to rotate inside the movable material frame 4 and on the material supporting table 3, and then the right side accumulated feed body (identified as A1 in the middle) flows to the left under the lifting of the flap 301, is evenly distributed, and is reduced and compacted under the auxiliary action of the vibration generated by the second driving block 11 and the second protrusion 1101.
