Description

Technical Field

[0001] This utility model relates to the field of juvenile fish farming, specifically a device for precise feeding of juvenile catfish. Background Technology

[0002] The term "juvenile Kanglang fish" refers to the larval stage of Kanglang fish, a species endemic to Fuxian Lake. Kanglang fish belongs to the Bagridae family and is a small, bottom-dwelling freshwater fish. Adults typically reach a length of 10-15 centimeters.

[0003] In raising juvenile silver carp, to further improve the survival rate, they are usually raised in indoor artificial ponds. Feeding is typically done manually by scattering feed, which cannot ensure uniform distribution. Furthermore, if the feed is too dense, it can cause overcrowding, leading to oxygen deprivation and injury in some juveniles, thus reducing the survival rate. Therefore, we propose a precision feeding device for juvenile silver carp to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a precise feeding device for juvenile bream to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precise feeding device for juvenile bream, comprising a conveying mechanism, wherein a limiting member is provided on the outer surface of the conveying mechanism, and a feeding mechanism is provided inside the limiting member.

[0006] Preferably, the conveying mechanism includes a support cylinder, the upper surface of which is provided with a groove, a movable block is slidably connected to the inner wall of the groove, a first bearing is embedded inside the groove, a threaded rod is connected to the inner ring of the first bearing, and a first motor is connected inside the groove.

[0007] Preferably, the feeding mechanism includes a housing, a support plate connected to the upper surface of the housing, a second motor connected to the upper surface of the support plate, a second bearing embedded in the outer surface of the support plate, a rotating rod connected to the inner ring of the second bearing, a threaded blade connected to the outer surface of the rotating rod, a conveying pipe connected to the bottom surface of the housing, and two connecting plates connected to the outer surface of the housing.

[0008] Preferably, the limiting component includes two limiting plates, with a limiting rod connected to one side of the two limiting plates that are close to each other. A limiting block is slidably connected to the outer surface of the limiting rod. The upper surface of the limiting block is connected to the bottom surface of one of the connecting plates. The left side of both limiting plates is connected to the right side of the support cylinder.

[0009] Preferably, the interior of the movable block is threadedly connected to the outer surface of the threaded rod, and the end of the threaded rod away from the first bearing is connected to the output end of the first motor.

[0010] Preferably, the end of the rotating rod away from the second bearing passes through the housing and extends into the interior of the conveying pipe, the end of the rotating rod near the second bearing passes through the second bearing and extends above the support plate, the end of the rotating rod near the second bearing is connected to the output end of the second motor, and the outer surface of the other connecting plate is connected to the right side of the moving block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention features a second motor that drives a rotating rod to rotate, which in turn drives a spiral blade to rotate. This causes the feed inside the outer casing to enter the conveying pipe along with the rotating spiral blade, ensuring uniform feeding. A first motor drives the spiral rod to rotate, and the moving block moves the feeding mechanism back and forth in the direction of the spiral rod's rotation. This increases the uniformity of feed distribution during feeding, effectively preventing uneven feeding from causing juvenile fish to squeeze each other and suffer from oxygen deficiency. It also improves feeding efficiency. Attached Figure Description

[0020] The conveying mechanism 1 includes a support cylinder 101, with a groove 102 on its upper surface. A moving block 103 is slidably connected to the inner wall of the groove 102. A first bearing 104 is embedded inside the groove 102, and a threaded rod 105 is connected to the inner ring of the first bearing 104. A first motor 106 is connected inside the groove 102. The feeding mechanism 2 includes a housing 201, with a support plate 202 connected to its upper surface. A second motor 203 is connected to the upper surface of the support plate 202, and a threaded rod 105 is embedded on the outer surface of the support plate 202. The second bearing 204 has a rotating rod 205 connected to its inner ring. The outer surface of the rotating rod 205 is connected to a threaded blade 206. The bottom surface of the outer casing 201 is connected to a conveying pipe 207. The outer surface of the outer casing 201 is connected to two connecting plates 208. The threaded blade 206 ensures that the feed falls evenly and improves the uniformity of the feed during the fall. The support cylinder 101 can be selected according to the diameter of the indoor breeding pond. At the same time, the support cylinder 101 can be installed above the breeding pond by the cooperation of screws, metal parts and external tools.

[0021] The limiting component 3 includes two limiting plates 301. A limiting rod 302 is connected to one side of each limiting plate 301 that is close to the other. A limiting block 303 is slidably connected to the outer surface of the limiting rod 302. The upper surface of the limiting block 303 is connected to the bottom surface of one of the connecting plates 208. The left sides of both limiting plates 301 are connected to the right side of the support cylinder 101. The interior of the moving block 103 is threadedly connected to the outer surface of the threaded rod 105. The end of the threaded rod 105 furthest from the first bearing 104 is connected to the output of the first motor 106. The rotating rod 205 is connected at one end. The end of the rotating rod 205 away from the second bearing 204 passes through the outer shell 201 and extends into the interior of the conveying pipe 207. The end of the rotating rod 205 near the second bearing 204 passes through the second bearing 204 and extends above the support plate 202. The end of the rotating rod 205 near the second bearing 204 is connected to the output end of the second motor 203. The outer surface of the other connecting plate 208 is connected to the right side of the moving block 103. Through the cooperation of the limiting rod 302 and the limiting block 303, the stability of the feeding mechanism 2 during movement can be ensured.

[0022] Working principle: When in use, feed is first put into the outer shell 201, and then the second motor 203 is started. The second motor 203 will drive the rotating rod 205 and the threaded blade 206 to rotate. The feed inside the outer shell 201 will be fed out gradually through the rotation of the threaded blade 206. The feed will fall through the conveying pipe 207. At the same time, the first motor 106 is started. The first motor 106 will drive the threaded rod 105 to rotate. The moving block 103 will move back and forth in the direction of rotation of the threaded rod 206. At the same time, the outer shell 201 will be moved through the connecting plate 208. As the outer shell 201 moves, the limiting block 303 will move on the limiting rod 302, thereby ensuring that the feeding mechanism 2 ensures uniformity in feeding and distribution.
