Description

Technical Field

[0001] The invention relates to a breeding and feeding system, in particular to a breeding and feeding system for a three-dimensional apartment. Background Art

[0002] Three-dimensional apartment aquaculture is a new aquaculture model that has emerged in the aquaculture industry in recent years. Using a three-dimensional apartment consisting of individual culture boxes, each shrimp, crab, or other aquatic creature is individually raised, effectively avoiding injuries and deaths caused by fighting among the animals. Traditional manual feeding methods are blind and random, easily leading to feed waste and residual feed affecting water quality. Currently, automated feeding systems are increasingly being adopted in three-dimensional apartment aquaculture.

[0003] The existing feeding system includes a controller, a feeding machine, a traveling device, and multiple feeding devices. The traveling device is mounted above the multiple feeding devices. The number of feeding devices is the same as the number of groups of three-dimensional apartments in the three-dimensional apartment breeding farm. Each feeding device corresponds to a group of three-dimensional apartments and is installed above the group of three-dimensional apartments. Each feeding device has multiple feeding hoses. The number of feeding hoses is equal to the number of breeding boxes in the corresponding group of three-dimensional apartments. The multiple feeding hoses correspond one-to-one with the breeding boxes in the corresponding group of three-dimensional apartments. The lower end of each feeding hose extends into a corresponding breeding box. In each feeding device, the upper ends of the multiple feeding hoses are distributed in multiple rows and columns. Driven by a screw rod or a synchronous belt, the feeding machine can travel along the traveling device to the top of the multiple feeding devices to feed multiple groups of three-dimensional apartments. When feeding a group of 3D apartments, the feeding machine moves above the corresponding feeding device. Each time it moves, it moves above a feeding hose and loads the bait into the feeding hose. The bait then falls along the feeding hose into the corresponding breeding box, completing the feeding of the breeding box. When all the feeding hoses of the feeding devices corresponding to a group of 3D apartments are loaded with bait, the feeding machine moves to the next feeding device driven by a screw rod or synchronous belt to feed the next group of 3D apartments.

[0004] The existing three-dimensional apartment feeding system has the following problems: when feeding, the feeding machine needs to move to the top of each feeding device, and then move horizontally and vertically to realize the feeding of each feeding hose in each feeding device. That is, every time the feeding machine completes the feeding of a group of three-dimensional apartments, it needs to complete the vertical and horizontal walking processes. Each group of three-dimensional apartments generally has at least 100 breeding boxes, and the three-dimensional apartment farms have dozens of groups of three-dimensional apartments. Feeding according to this process is extremely cumbersome, the feeding efficiency is low, and it is easy to cause wear of components and reduce the service life. In addition, the feeding machine uses a synchronous belt or screw walking method, which is only suitable for short-distance walking. The length of the breeding site is tens of meters. Over long distances, the synchronous belt or screw is difficult to center and the transmission accuracy is poor, which easily leads to reduced feeding accuracy. Summary of the Invention

A metal sheet for identifying the inductive proximity switch is installed at both ends of the top of each group of three-dimensional apartments along the direction of travel of the track trolley. One of the metal sheets is used to identify whether the track trolley has arrived above the three-dimensional apartment and is referred to as the first metal sheet. The other is used to identify whether the track trolley is about to leave the three-dimensional apartment and is referred to as the second metal sheet. When it is necessary to feed a group of three-dimensional apartments, the track trolley moves along the travel track under the control of the controller. When the first metal sheet on the group of three-dimensional apartments is sensed by the inductive proximity switch, it indicates that the When the rail trolley arrives above the group of three-dimensional apartments, the inductive proximity switch generates a signal and sends it to the controller. The controller controls the rail trolley to move above the group of three-dimensional apartments in turn according to the preset stroke to feed bait at each feeding point. When the feeding of a feeding point is completed, the controller controls the rail trolley to move to the next feeding point to continue feeding bait until the second metal sheet on the group of three-dimensional apartments is sensed by the inductive proximity switch, indicating that the feeding of the group of three-dimensional apartments is completed. At this time, the inductive proximity switch generates a signal and sends it to the controller. The controller controls the rail trolley to move to the next group of three-dimensional apartments to feed bait or return to the initial position.

[0010] The walking track is realized by an I-beam track, including an upper wing plate, a lower wing plate and a web plate. The upper wing plate and the lower wing plate are spaced apart from each other, and the web plate is located between the upper wing plate and the lower wing plate, and is fixedly connected to the upper wing plate and the lower wing plate respectively. The web plate divides the area between the upper wing plate and the lower wing plate into a left area and a right area; the rail trolley includes a frame, two T-type driving wheels, two T-type driven wheels, a driving gear, a second stepping motor, a mounting plate for mounting a feeder, and a And a clamping wheel for preventing the rail trolley from jumping up and down; the frame includes a left side plate, a right side plate and a plurality of connecting shafts, the left side plate and the right side plate are arranged at intervals from left to right, and the plurality of connecting shafts are arranged in parallel and at intervals from front to back, each connecting shaft passes through the left side plate and the right side plate respectively, and a fixing nut is installed at the left and right ends of each connecting shaft respectively, two T-shaped driving wheels and two T-shaped driven wheels are located between the left side plate and the right side plate, wherein the two T-shaped driving wheels are installed on the right side plate at intervals from front to back, and the two T-shaped driven wheels are installed on the right side plate at intervals from front to back. The front and rear plates are installed on the left side plate at intervals, and a circle of teeth is provided on the circumferential surface of the two T-shaped driving wheels. The driving gear is respectively engaged with the two T-shaped driving wheels, and the driving gear is installed on the output shaft of the second stepper motor, and the second stepper motor is installed on the right side plate; the mounting plate is located below the left side plate and the right side plate, and is fixed on multiple connecting shafts. The clamping wheel is located between the left side plate and the right side plate and above the mounting plate, and when mounted on the mounting plate, the axial directions of the two T-shaped driving wheels, the two T-shaped driven wheels and the clamping wheel are all in the horizontal direction. When the rail trolley is located on the walking track, the two T-shaped driving wheels are located in the right area and supported by the lower wing plate, and the two T-shaped driven wheels are located in the left area and supported by the lower wing plate. The clamping wheel, multiple connecting shafts and the mounting plate are all located below the lower wing plate, and the lower end surface of the lower wing plate is tangent to the clamping wheel to prevent the rail trolley from jumping up and down and ensure the stability of the rail trolley.

[0011] The rail trolley further comprises an anti-roll device for preventing the rail trolley from overturning when it is subjected to a roll or lateral force.

[0012] The anti-roll device includes four anti-roll units, which are respectively referred to as a first anti-roll unit, a second anti-roll unit, a third anti-roll unit, and a fourth anti-roll unit. The first anti-roll unit and the second anti-roll unit are installed on the left side of the left side plate, and the third anti-roll unit and the fourth anti-roll unit are installed on the right side of the right side plate. The first anti-roll unit includes a mounting bracket, a sliding rod, a preload spring, a first adjusting nut, a second adjusting nut and a roller, wherein the mounting bracket is mounted on the left side plate and is located on the left side of the left side plate, an inner cavity is provided inside the mounting bracket, the sliding rod passes through the mounting bracket and the left side plate in sequence, the axial direction of the roller is along the vertical direction, the roller is mounted on the right end of the sliding rod and is tangent to the belly plate, the preload spring is located in the inner cavity, the preload spring is sleeved on the sliding rod, the first adjusting nut is located on the left side of the mounting bracket, the first adjusting nut is mounted on the left end of the sliding rod and contacts the mounting bracket, the second adjusting nut is located in the inner cavity, the second adjusting nut is mounted on the sliding rod and contacts the right side wall of the inner cavity. When the trolley is in contact with the first anti-roll unit, one end of the pre-tightening spring contacts the second adjusting nut, and the other end contacts the left side wall of the inner cavity; in the initial state, the pre-tightening spring is in a compressed state, and the roller and the belly plate remain tangent but have no contact force; the second anti-roll unit is symmetrical with the first anti-roll unit front to back, the third anti-roll unit is symmetrical with the first anti-roll unit left to right, and the fourth anti-roll unit is symmetrical with the second anti-roll unit left to right; in the initial state, the pre-tightening springs of the four anti-roll units remain in a compressed state, and the roller and the belly plate are tangent but have no contact force. When the rail trolley is walking on the walking track, if there is a tendency to tip to one side, the sliding rod will slide relative to the mounting frame. At this time, the pre-tightening spring will generate a reverse force to offset the tipping force, thereby ensuring that the rail trolley walks along the original path.

[0013] Compared with the prior art, the advantage of the present invention is that in the initial state, the second feeding baffle of each weighing module closes the discharge port of its storage chamber, and the m bait guide tubes correspond to the m feeding holes in a certain feeding hole group and are connected up and down. The torsion spring at each feeding unit is compressed, and the first feeding baffle closes the upper end opening of the second channel. When it is necessary to feed, the user first sets the single feeding amount in the controller according to the feeding demand, and loads the bait into the m funnel shells, and then turns on the controller. The controller enters the feeding working state, and first drives the track trolley along the walking track according to the preset program to move to a feeding point where feeding is required. At this feeding point, The m feeding hole groups correspond one to one with the m feeding units of the feeding module at the feeding point. In a corresponding feeding hole group and a feeding unit, the m bait guide pipes of the feeding hole group are connected one to one with the m guide pipes of the feeding unit. The controller first controls the feeding drive motors of the m spiral feeding mechanisms to start. At this time, the feeding drive motor in each spiral feeding mechanism rotates, driving the conveying screw connected to it to rotate. The conveying screw will output the bait that falls from the corresponding funnel shell into the feeding pipe to the discharge port of the feeding pipe, and then output it to the storage chamber of the corresponding weighing module through the discharge port of the feeding pipe. The weighing sensor of each weighing module measures the bait in real time. The weight of the bait in its storage chamber is measured, and the real-time weighing weight is fed back to the controller. When the real-time weighing weight fed back by the weighing sensor of a certain weighing module is equal to the single bait feeding amount, the controller first controls the feeding drive motor of the spiral feeding mechanism corresponding to the weighing module to turn off and stop working. At this time, the spiral feeding mechanism corresponding to the weighing module no longer outputs bait, and then controls the baffle driving motor of the weighing module to work, driving the second unloading baffle connected to it to rotate, so that the discharge port of the storage chamber of the weighing module is opened. At this time, the bait in the storage chamber of the weighing module falls into a guide pipe through a bait guide pipe, and the bait in the storage chamber of the weighing module is discharged. After all the bait in the weighing module has fallen, the controller controls the baffle driving motor of the weighing module again to work, drives the second feeding baffle connected thereto to rotate, so that the discharge port of the storage chamber of the weighing module is closed again, and the weighing module completes one feeding. After the feeding of the bait in the storage chambers of the m weighing modules is completed, the controller first controls the first blower of the material receiving unit to start blowing, blows the m first feeding baffles, so that the upper end openings of the m second channels are opened, and the bait falls into the m feeding hoses through the m second channels, and then controls the second blower to start blowing, blows the bait in the m feeding hoses into the m breeding boxes, and completes the feeding of the m breeding boxes;Then control it to control the first stepper motor to work, the first stepper motor drives the rotating disc to rotate so that the m bait guide tubes correspond to the m feeding holes in the next feeding hole group and dock up and down, and then repeat the above action to carry out the next feeding, and repeat it over and over again until all the breeding boxes corresponding to the feeding module at the feeding point are fed. Among them, the feeding device is composed of a rotary feeding device, a stepper motor and a feeding device, which has a simple structure and is easy to operate and install. The rotary feeding device adopts a combination of a rotating disc and a bait guide tube, which can realize efficient and accurate bait delivery. The weight of each packaged bait is the same, which is suitable for large-scale and efficient bait delivery. The feeding device adopts a combination of a guide plate and a feeding hole, which can be adjusted and replaced according to needs, and is suitable for bait delivery of different specifications. The feeding device adopts a stepper motor. The motor drives the rotating disc, enabling precise control and adjustment. The combined use of the bait guide tube and weighing module ensures accurate and stable bait delivery. The feeding device can be manufactured using low-cost materials and components, meeting production needs. Operation is simple, requiring no specialized skills, and reducing both production and labor costs. The present invention boasts a simple and compact overall structure, easy operation, low cost, and wide applicability. Furthermore, the circular arrangement of m receiving units at each feeding point allows for feeding of m*m breeding boxes, simplifying the feeding process and increasing efficiency. The centralized feeding points significantly shorten the length of the travel track, reducing component wear. Furthermore, the high transmission accuracy prevents reduced feeding accuracy.

The feeding drive motor 24 is used to drive the conveying screw 25 to rotate or not under the control of the controller 1. A feed port 26 connected to the interior of the feeding pipe 23 is provided. The feed port 26 of the feeding pipe 23 is used to connect and pass through the discharge port of the funnel shell 17. The other end of the feeding pipe 23 is provided with a discharge port 27 for outputting the bait downward. The discharge port 27 of the feeding pipe 23 is used to output the bait.

[0031] In this embodiment, as shown in Figures 10 (a) and 10 (b), each weighing module 14 includes a storage chamber 28 for storing bait, a second unloading baffle 29, a baffle drive motor 30 and a weighing sensor 31. The baffle drive motor 30 and the weighing sensor 31 are respectively connected to the controller 1. The weighing sensor 31 is used to weigh the weight of the bait in the storage chamber 28, obtain the real-time weighing weight and output it to the controller 1. The storage chamber 28 has a receiving port and a discharge port. The receiving port of the storage chamber 28 is used to receive the bait output by the spiral feeding mechanism 16. The second unloading baffle 29 is installed on the motor shaft of the baffle drive motor 30. The second unloading baffle 29 is located below the discharge port of the storage chamber 28. The baffle drive motor 30 is used to drive the second unloading baffle 29 to rotate to open or close the discharge port of the storage chamber 28.

[0032] The working process of the three-dimensional apartment farming model feeding system of this embodiment is as follows: in the initial state, the second feed baffle 29 of each weighing module 14 closes the discharge port of its storage chamber 28, the m feed guide tubes 19 are connected to the m feed holes 22 in a certain feed hole group 21 in a one-to-one correspondence, the torsion spring 84 at each feed receiving unit 5 is compressed, and the first feed baffle 82 closes the upper end opening of the second channel 81;When feeding is needed, the user first sets the single feeding amount in the controller 1 according to the feeding demand, and loads the bait into the m funnel shells 17, and then turns on the controller 1. The controller 1 enters the feeding working state, and first drives the track trolley 10 to walk along the walking track 11 to a feeding point where bait needs to be fed according to the preset program. At the feeding point, the m feeding hole groups 21 correspond one-to-one with the m feeding units 5 of the feeding module 3 at the feeding point. In a corresponding feeding hole group 21 and a feeding unit 5, the m bait guide pipes 19 of the feeding hole group 21 are connected one-to-one with the m guide pipes 7 of the feeding unit 5. The controller 1 first controls the m screws The feeding drive motor 24 of the spiral feeding mechanism 16 is started. At this time, in each spiral feeding mechanism 16, the feeding drive motor 24 rotates, driving the conveying screw 25 connected thereto to rotate. The conveying screw 25 will drop the bait from the corresponding funnel shell 17 into the feeding tube 23 and output it to the discharge port of the feeding tube 23, and then output it to the storage chamber 28 of the corresponding weighing module 14 through the discharge port of the feeding tube 23. The weighing sensor 31 of each weighing module 14 measures the weight of the bait in its storage chamber 28 in real time, obtains the real-time weighing weight and feeds it back to the controller 1. When the real-time weighing weight fed back by the weighing sensor 31 of a certain weighing module 14 is equal to the single bait feeding amount, , the controller 1 first controls the feeding drive motor 24 of the spiral feeding mechanism 16 corresponding to the weighing module 14 to turn off and stop working. At this time, the spiral feeding mechanism 16 corresponding to the weighing module 14 no longer outputs bait. Then, the baffle driving motor 30 of the weighing module 14 is controlled to work, driving the second unloading baffle 29 connected thereto to rotate, so that the discharge port of the storage chamber 28 of the weighing module 14 is opened. At this time, the bait in the storage chamber 28 of the weighing module 14 falls into a guide pipe 7 through a bait guide pipe 19. After all the bait in the storage chamber 28 of the weighing module 14 falls, the controller 1 controls the baffle driving motor 30 of the weighing module 14 again. The plate drive motor 30 works, driving the second unloading baffle 29 connected thereto to rotate, so that the discharge port of the storage chamber 28 of the weighing module 14 is closed again, and the weighing module 14 completes one feeding. After the bait in the storage chamber 28 of the m weighing modules 14 is fed, the controller 1 first controls the first blower of the material receiving unit 5 to start blowing, blows the m first unloading baffles 82, opens the upper end openings of the m second channels 81, and the bait falls into the m unloading hoses 9 through the m second channels 81, and then controls the second blower to start blowing, blows the bait in the m unloading hoses 9 into the m breeding boxes 4, and completes the feeding of the m breeding boxes 4;Then, the first stepper motor 17 is controlled to work, and the first stepper motor 17 drives the rotating disc 18 to rotate so that the m bait guide tubes 19 are connected to the m feeding holes 22 in the next feeding hole group 21 in a one-to-one correspondence. Then, the above action is repeated to carry out the next feeding, and the cycle repeats until all the breeding boxes 4 corresponding to the feeding module at the feeding point are fully fed. Therefore, the m feeding units 5 are distributed in a circular pattern at each feeding point of the present invention, and m*m breeding boxes 4 can be fed at one feeding point. The feeding process is simple and the feeding efficiency is high. At the same time, due to the concentration of feeding points, the length of the walking track 11 can be greatly shortened, which is not easy to cause component wear. The transmission accuracy is high and will not cause a decrease in feeding accuracy.

The other is used to identify whether the rail trolley 10 is about to leave the three-dimensional apartment, and is referred to as the second metal sheet. When it is necessary to feed a group of three-dimensional apartments, the rail trolley 10 moves along the travel track 11 under the control of the controller 1. When the first metal sheet on the group of three-dimensional apartments is When sensed by the inductive proximity switch, it indicates that the rail trolley 10 has arrived above the group of three-dimensional apartments. At this time, the inductive proximity switch generates a signal and sends it to the controller 1. The controller 1 controls the rail trolley 10 to move above the group of three-dimensional apartments in turn according to the preset stroke to feed bait at each feeding point. When the feeding of a feeding point is completed, the controller 1 controls the rail trolley 10 to move to the next feeding point to continue feeding bait until the second metal sheet on the group of three-dimensional apartments is sensed by the inductive proximity switch, indicating that the feeding of the group of three-dimensional apartments is completed. At this time, the inductive proximity switch generates a signal and sends it to the controller 1. The controller 1 controls the rail trolley 10 to move to the next group of three-dimensional apartments to feed bait or return to the initial position.
