Description

Technical Field

[0001] The invention relates to the technical field of feeding equipment, in particular to a circulating aquaculture feeding device. Background Art

[0002] Aquaculture is the activity of breeding aquatic economic animals and plants by humans using waters available for breeding, according to the ecological habits of the breeding objects and the requirements for the water environment conditions, using aquaculture techniques and facilities. In order to strictly control the temperature and other conditions required for the breeding process, breeders build factories to breed, which saves manpower in the breeding process. Tracks will be built in the breeding ponds, and feeding devices will slide on the tracks. When feeding, the staff will pour the feed into the feeding box, and the feeding box will spread the feed into the breeding pond by sliding on the track.

[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figures 1 to 10 :

[0031] A circulating water aquaculture feeding device, comprising a ground rail 1 installed on both sides of a culture pond, and a mobile gantry 2 slidably installed on the ground rail 1, the ground rail 1 extends along the flow direction of circulating water in the culture pond; the mobile gantry 2 comprises two side brackets 21, the bottom of the side bracket 21 is provided with a first roller 211, and a first rotating driver 212 driving the first roller 211 to rotate, the first roller 211 rolls on the ground rail 1, and a telescopic guide rail 22 extending horizontally perpendicular to the length direction of the ground rail 1 is provided between the two side brackets 21; a sliding base 3 is slidably installed on the telescopic guide rail 22, and a sliding base 3 is fixedly installed on the sliding base 3 There is a feeding box 4, a discharge port 41 is arranged at the bottom of the feeding box 4, side mounting strips 411 extending vertically downward are arranged in the middle of both sides of the discharge port 41, and the side mounting strips 411 are distributed along the length direction of the telescopic guide rail 22. A guide plate 42 is rotatably installed on the discharge port 41, and the guide plate 42 is inserted into the circulating water of the breeding pond and is driven to rotate by the water flow. A detection unit 5 for detecting the rotation direction of the guide plate 42 is arranged on one side of the feeding box 4, and the detection unit 5 is connected to the first rotation driver 212 of the mobile gantry 2 through the controller signal, and the first rotation driver 212 drives the mobile gantry 2 to move in the reverse direction of the circulating water flow.

[0032] When the breeding and feeding device of the present invention is in use, the staff lays the ground rail 1 on the ground on both sides of the breeding pond, the mobile gantry 2 moves along the ground rail 1, and the sliding base 3 drives the feeding box 4 to move along the mobile gantry 2, so as to realize feeding in multiple breeding ponds. The ground rail 1 in this embodiment is installed on the ground, which reduces the difficulty of installation and avoids the potential safety hazards of the mobile gantry 2 and the sliding base 3 being suspended in the air. The ground rail 1 is located on the ground, which can effectively prevent the water vapor in the breeding pond from corroding the ground rail 1 and affecting the service life of the ground rail 1. The mobile gantry 2 in this embodiment is slidably installed on the ground rail 1 on both sides of the breeding pond through two side brackets 21. The mobile gantry 2 and the ground rail 1 are detachable, so that it is convenient for the staff to disassemble the mobile gantry 2 when no feeding is needed. The telescopic guide rail 22 arranged between the two side brackets 21 can be extended according to the width of the breeding pond, so that the sliding base 3 can drive the feeding box 4 to move to various positions along the telescopic guide rail 22 of the mobile gantry 2 for feeding, thereby improving the application range of the equipment. The ground rail 1 in this embodiment is along the circulation in the breeding pond. The mobile gantry 2 can drive the feeding box 4 to move along the direction of the circulating water flow. The feeding box 4 of this embodiment is provided with a discharge port 41 at the bottom, and side mounting strips 411 are provided on both sides of the middle position of the discharge port 41. The guide plate 42 is rotatably mounted on the side mounting strips 411. When the guide plate 42 is inserted into the water of the breeding pond, the resistance of the circulating water to the guide plate 42 will push the guide plate 42 to rotate. The detection unit 5 provided on the feeding box 4 detects the rotation direction of the guide plate 42, thereby sending a signal to the driving mobile gantry through the controller. 2 is rotated on the first rotating driver 212, so that the first rotating driver 212 drives the mobile gantry 2 to move in the reverse direction of the circulating water flow, and drives the feeding box 4 to the upstream of the water flow of the breeding pool for feeding. When the guide plate 42 is attached to the edge of the breeding pool, it tilts, and the feed in the feeding box 4 is discharged to the guide plate 42 through the discharge port 41, and enters the breeding pool along the inclined guide plate 42. Driven by the water flow, it flows evenly into the breeding pool, ensuring that the fed feed is evenly distributed in the breeding pool to avoid accumulation. The first rotating driver 212 in this embodiment can be a servo motor.

[0033] In order to solve the problem of how the detection unit 5 detects the rotation direction of the guide plate 42 and thus controls the moving direction of the mobile gantry 2, the following features are specifically set:

[0034] The guide plate 42 is provided with shafts 421 on both sides, and the shafts 421 are respectively inserted into the side mounting strips 411, and the shafts 421 are also provided with connecting plates 422, and the connecting plates 422 extend upward along the length direction of the guide plate 42; the detection unit 5 includes a limit frame 51 slidably installed on one side of the feeding box 4, and a linear driver 52 driving the limit frame 51 to move in the vertical direction, and the two ends of the limit frame 51 are respectively provided with first side frame strips 511 extending to both sides of the side mounting strips 411, and the first side frame strips 511 are respectively fixedly installed with sensors 512, and the working of the sensor 512 The end is arranged toward the middle of the limit frame 51; the detection unit 5 also includes two bonding plates 53, the bonding plates 53 are located between the two first side frame strips 511 and extend vertically, a plurality of horizontal insertion rods 531 are arranged on the bonding plates 53, the bonding plates 53 are respectively inserted into the first side frame strips 511 through the insertion rods 531, and springs 532 are sleeved on the insertion rods 531, the springs 532 elastically connect the bonding plates 53 and the first side frame strips 511, the elastic force of the springs 532 causes the bonding plates 53 to move toward the middle of the limit frame 51, and a limiting head 533 is arranged at one end of the insertion rod 531 away from the bonding plates 53.

[0035] The guide plate 42 in this embodiment is inserted on the side mounting strip 411 through the shaft 421, and the shaft 421 can be located at the upper end of the guide plate 42. The connecting plate 422 arranged on the shaft 421 is located inside the limit frame 51 of the detection unit 5 and keeps rotating in the same direction and angle as the guide plate 42. The first side frame strips 511 arranged on both sides of the limit frame 51 are elastically installed with bonding plates 53. When the guide plate 42 is inserted into the water of the breeding pond and pushed by the water flow, the guide plate 42 and the connecting plate 422 rotate synchronously, and the connecting plate 422 rotates to contact the bonding plate 53 on one side and push the bonding plate 53 to move. The sensor 512 on the first side frame strip 511 detects the movement of the bonding plate 53 and generates a signal to the controller, and the controller controls the first rotation driver 212 is started to move the mobile gantry 2 along the moving direction of the bonding plate 53. The sensor 512 in this embodiment can be a photoelectric distance sensor. The staff can set the position of the bonding plate 53 detected by the sensor 512. When the sensor 512 detects that the straight-line distance between the bonding plate 53 and the first side frame bar 511 reaches the minimum vertical, it can be determined that the mobile gantry 2 has driven the guide plate 42 to move to the side of the bonding breeding pool. At this time, the sensor 512 sends a signal again to stop the first rotation driver 212 to maintain the position of the feeding box 4. At this time, the feeding box 4 is located upstream of the water flow in the breeding pool, and the rotation angle of the guide plate 42 can make the feed dropped from the discharge port 41 move along the surface of the guide plate 42 into the breeding pool.

[0036] In order to solve the problem of how to keep the guide plate 42 vertically inserted into the water flow of the breeding pond in the initial state, the following features are specifically set:

[0037] The limiting frame 51 is also provided with a second side frame bar 513 below the first side frame bar 511. The second side frame bar 513 extends vertically. An opening is provided between the two second side frame bars 513 for allowing the top end of the connecting plate 422 to enter the interior of the limiting frame 51. The straight-line distance between the second side frame bars 513 is equal to the width of the connecting plate 422.

[0038] The straight-line distance between the first side frame strips 511 of the limit frame 51 in this embodiment ensures that the connecting plate 422 can rotate between the first side frame strips 511 and drive the bonding plate 53 to move. The limit frame 51 in this embodiment is located below the first side frame strips 511 and a second side frame strip 513 is also provided. The second side frame strip 513 is connected to the first side frame strip 511. The linear drive 52 drives the limit frame 51 to stay in the initial position. At this time, the connecting plate 422 does not enter the limit frame 51. The guide plate 42 can rotate at any angle. When the mobile gantry 2 moves along the ground rail 1, the guide plate 42 can move between multiple breeding pools. When the guide When the plate 42 remains vertical under the action of gravity, the linear actuator 52 can drive the limit frame 51 to move in the vertical direction, so that the second side frame strip 513 moves down to fit the two sides of the connecting plate 422, fixes the connecting plate 422 to prevent it from rotating, and the connecting plate 422 cannot rotate, so the guide plate 42 cannot rotate, so the guide plate 42 is inserted into the water flow and will not be pushed by the water flow to rotate, when the linear actuator 52 continues to drive the limit frame 51 to move down until the second side frame strip 513 is completely separated from the connecting plate 422, and the connecting plate 422 enters the interior of the limit frame 51, the guide plate 42 can rotate to detect the moving direction of the mobile gantry 2. The linear actuator 52 in this embodiment can be a linear cylinder or an electric push rod, etc.

[0039] In order to solve the problem of how to improve the detection efficiency of the detection unit 5, the following features are specifically set:

[0040] When the elastic force of the spring 532 causes the limiting head 533 to fit one side of the first side frame strip 511 , the straight-line distance between the fitting plates 53 is equal to the straight-line distance between the second side frame strips 513 .

[0041] The bonding plate 53 in this embodiment is moved to the position where the limit head 533 is bonded to the first side frame strip 511 by the elastic force of the spring 532. The position of the bonding plate 53 under the elastic force of the spring 532 is the initial position. At this time, the distance between the bonding plates 53 should be equal to the straight-line distance between the second side frame strips 513. Therefore, when the connecting plate 422 enters the limiting frame 51, the bonding plate 53 is kept in contact with the two sides of the top of the connecting plate 422. At the moment when the second side frame strip 513 is separated from the connecting plate 422, the rotation of the connecting plate 422 can drive the bonding plate 53 to move, so that the detection unit 5 can generate a signal to control the movement of the mobile gantry 2, thereby improving the detection efficiency of the detection unit 5.

[0042] In order to solve the problem of how to control the limit frame 51 to move in the vertical direction and ensure that the limit frame 51 moves to the specified position, the following features are specifically set:

[0043] The feeding box 4 is provided with two positioning blocks 43 on one side of the installation limit frame 51. The positioning block 43 is located in the limit frame 51 and fits against the inner wall of the first side frame strip 511. When the top of the limit frame 51 fits against the upper side of the positioning block 43, the second side frame strip 513 is located below the connecting plate 422. When the top end of the fitting plate 53 fits against the bottom of the positioning block 43, the bottom end of the second side frame strip 513 is located above the connecting plate 422.

[0044] The positioning block 43 provided on the feeding box 4 in this embodiment can fit the inner wall of the first side frame strip 511 to keep the limit frame 51 moving in the vertical direction. When the linear drive 52 drives the top of the limit frame 51 to fit the upper side of the positioning block 43, the second side frame strip 513 is located below the connecting plate 422. At this time, the connecting plate 422 can rotate in the limit frame 51. When the linear drive 52 drives the top of the fitting plate 53 to fit below the positioning block 43, the limit frame 51 cannot continue to move up. At this time, the bottom end of the second side frame strip 513 is located above the connecting plate 422, and the guide plate 42 can be rotated at will to facilitate the movement of the gantry 2 along the ground rail 1.

[0045] In order to realize that the telescopic guide rail 22 can change its length and the sliding base 3 can move along the telescopic guide rail 22, the following features are specifically provided:

[0046] The telescopic guide rail 22 includes two parallel main rails 221 and two parallel auxiliary guide rails 222. One end of the main rail 221 is fixedly connected to one of the side brackets 21, and the auxiliary guide rail 222 is located between the two main rails 221. A limiting groove 223 extending along the length direction of the main rail 221 is arranged on the inner side of the main rail 221, and a limiting block 224 with the same width as the limiting groove 223 is arranged on the outer side of the telescopic guide rail 22. The limiting block 224 moves in a limited position in the limiting groove 223. A limiting baffle 225 for blocking the limiting groove 223 is arranged on the end of the main rail 221 away from the side bracket 21.

[0047] A plurality of drive shafts 31 are arranged at the bottom of the sliding base 3. The drive shafts 31 extend in a horizontal direction perpendicular to the telescopic guide rail 22. Four second rollers 32 are coaxially arranged on the drive shaft 31. The second rollers 32 roll along the main guide rail 221 and the auxiliary guide rail 222 respectively. A second rotating driver 33 for driving the drive shaft 31 to rotate is also arranged on the sliding base 3.

[0048] The telescopic guide rail 22 in this embodiment includes two main guide rails 221 and two auxiliary guide rails 222. The auxiliary guide rail 222 is located between the two main guide rails 221, and the limit block 224 on each auxiliary guide rail 222 is slidably installed in the limit groove 223 on the main rail 221. Therefore, the auxiliary guide rail 222 can move in the length direction of the main rail 221 and keep the overall level of the telescopic guide rail 22. In this embodiment, a plurality of driving shafts 31 are arranged at the bottom of the sliding base 3, and four second rollers are arranged on each driving shaft 31. The first roller 32 and the second roller 32 are respectively located on the main rail 221 and the auxiliary rail 222. When the sliding base 3 moves to the main rail 221, the second roller 32 rolls on the main rail 221, and the second roller 32 located on the auxiliary rail 222 is suspended. When the sliding base 3 moves to the auxiliary rail 222, the second roller 32 rolls on the auxiliary rail 222, and the second roller 32 located on the main rail 221 is suspended, thereby ensuring that the sliding base 3 can drive the feeding box 4 to move to various positions on the telescopic rail 22. In this embodiment, the second rotation driver 33 that drives the drive shaft 31 to rotate can be a servo motor.

[0049] In order to solve the problem of how to prevent the telescopic guide rail 22 from bending due to excessive force, the following features are specifically set:

[0050] One of the side brackets 21 is provided with at least two guide sleeves 23 extending horizontally perpendicular to the ground rail 1, and the other side bracket 21 is provided with a guide rod 24 inserted in the guide sleeve 23; a support base plate 231 is provided at the bottom of the end of the guide sleeve 23 away from the side bracket 21, and the support base plate 231 is used to support the main rail 221.

[0051] In this embodiment, a guide sleeve 23 and a guide rod 24 are further provided between the two side brackets 21. The guide rod 24 is inserted in the guide sleeve 23. When the width between the side brackets 21 changes, the guide rod 24 can move in the guide sleeve 23. The guide sleeve 23 and the guide rod 24 can support the gravity of the sliding base 3 and the feeding box 4, thereby preventing the telescopic guide rail 22 from being bent due to excessive force, and protecting the telescopic guide rail 22.

[0052] Working principle: The staff lays the ground rail 1 on the ground on both sides of the breeding pond, and the ground rail 1 extends along the flow direction of the circulating water in the breeding pond. The mobile gantry 2 moves along the ground rail 1, and the sliding base 3 drives the feeding box 4 to move along the mobile gantry 2. The feeding box 4 is provided with a discharge port 41 at the bottom, and the guide plate 42 is rotatably mounted on the side mounting strip 411 at the bottom of the discharge port 41. When the guide plate 42 is inserted into the water of the breeding pond, the resistance of the circulating water to the guide plate 42 will push the guide plate 42 to rotate, and the detection unit 5 set on the feeding box 4 detects the guide plate 41. The guide plate 42 rotates in the opposite direction of the circulating water flow direction, thereby sending a signal to the first rotary driver 212 through the controller, so that the first rotary driver 212 drives the mobile gantry 2 to move in the opposite direction of the circulating water flow direction, and drives the feeding box 4 to the upstream of the water flow of the breeding pond for feeding. When the guide plate 42 is attached to the edge of the breeding pond, it tilts, and the feed in the feeding box 4 is discharged onto the guide plate 42 through the discharge port 41, and enters the breeding pond along the inclined guide plate 42, and flows evenly into the breeding pond driven by the water flow, thereby ensuring that the fed feed is evenly distributed in the breeding pond.

[0053] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
