Description

Technical Field

[0001] The utility model relates to shrimp farming, in particular to a feeding device for a farming pond. Background Art

[0002] When shrimp fry are cultured, they are generally cultured in a breeding pond. Compared with the natural growth environment, the density of shrimp fry in the breeding pond is much higher. Therefore, during the breeding process, it is necessary to perform operations such as oxygenation, feeding, and cleaning the bottom of the breeding pond. During the feeding operation, the feed needs to be spread evenly on the surface of the breeding pond. When feeding artificially, the feed can be thrown and spread on the surface of the breeding pond, but it is more laborious. At present, there are also devices for feeding, which generally use mechanisms with conveying functions such as dragon blades and conveyor belts. Through these mechanisms, the feed in the silo outside the breeding pond is conveyed, and the feed finally falls into the breeding pond. Compared with artificial feeding, it can save labor, but this type of device still has the problem that the feed falls on one point and the feeding is not uniform enough. Utility Model Content

[0038] See also Figure 1 and Figure 5 A feeding device for a breeding pond includes a mounting frame 1, a shell 2, a feeding shaft 4, a feed sucker 6, a silo 5, a cover plate 3, a worm gear module 7, a motor 8, a cam 9 and a linkage assembly 10.

[0039] The first side and the second side of the bottom of the mounting frame 1 are provided with rollers 1a. That is, the rollers 1a on the first side and the second side contact the ground on both sides of the culture pond respectively, and the mounting frame 1 can be pushed to move along the culture pond.

[0040] See also Figure 2 and Figure 4 The shell 2 is cylindrical and fixedly connected to the top of the mounting frame 1, with its axis extending from the first side to the second side.

[0041] A first slit 2a for discharging materials is provided at the bottom of the shell 2, and a feed port 2b is provided at the top of the shell 2 near the first side.

[0042] The cover plate 3 is movably connected to the first gap 2a of the housing 2. That is, the cover plate 3 is switched between a state of blocking the first gap 2a and a state of not blocking the first gap 2a by movement of the cover plate 3 relative to the housing 2, such as sliding or rotating.

[0043] See also Figure 4 The feed shaft 4 is rotatably connected to the housing 2. Specifically, bearing seats are provided on the end surfaces of the first side and the second side of the housing 2, and the two shaft ends of the feed shaft 4 are respectively connected to the inner rings of the bearings in the two bearing seats. The feed shaft 4 also has a dragon blade 4a.

[0044] See also Figure 2 The silo 5 is fixedly connected to the mounting frame 1 and is used for placing feed.

[0045] The suction device 6 is an existing device. During the injection molding, the suction device 6 is also used to suck the plastic particles into the injection molding machine. The structure and principle of the suction device 6 will not be described in detail. The suction device 6 in the figure is only a simple illustration. The suction device 6 is fixedly connected to the feed inlet 2b of the housing 2 and is also connected to the silo 5. That is, the pipe on the suction device 6 is inserted into the feed in the silo 5. When the cover plate 3 blocks the first gap 2a, the feed is sucked in through the suction device 6, and the feed then falls from the feed inlet 2b into the housing 2 at a position close to the first side.

[0046] See also Figure 2 and Figure 5 The worm gear module 7 is fixedly connected to the mounting frame 1. Both ends of the worm need to pass through the housing as a connection end, and one end of the shaft corresponding to the worm gear passes through the housing as a connection end. One end of the worm is connected to the feed shaft 4.

[0047] The motor 8 is fixedly connected to the mounting frame 1, and the output shaft is connected to the other end of the worm in the worm gear module 7. That is, the motor 8 drives the feeding rod to rotate, and also drives the worm gear to rotate.

[0048] The cam 9 is connected to the worm wheel in the worm gear module 7, that is, the cam 9 is fixedly connected to the connecting end of the shaft corresponding to the worm wheel, and the cam 9 rotates synchronously with the worm wheel.

[0049] The linkage assembly 10 is arranged between the cam 9 and the cover plate 3, so that the cover plate 3 can be opened and closed once during the rotation of the cam 9. That is, the cam 9 is provided with a guide groove, which includes a larger first arc portion 9a and a smaller second arc portion 9b.

[0050] Optionally, the cover plate 3 is hinged to the housing 2, and the linkage assembly 10 includes a connecting portion 10a, a connecting rod 10b and a sliding block 10c.

[0051] The connecting portion 10a is connected to the mounting frame 1 by sliding up and down. The lower end of the connecting portion 10a is connected to the cover plate 3 by sliding. That is, during the rotation of the cover plate 3, the connection point between the cover plate 3 and the connecting portion 10a rotates with the cover plate 3. After decomposition, there are both vertical and horizontal movements. The lower end of the connecting portion 10a and the cover plate 3 are set to slide, and the horizontal movement of the connection point is balanced. The cover plate 3 can be driven to rotate by sliding the connecting portion 10a up and down. Specifically, the lower end of the connecting portion 10a is a connecting block 10a1 with a horizontal slide groove. The cover plate 3 is fixedly provided with a first connecting column 3a inserted into the slide groove. The diameter of the first connecting column 3a is equal to the width of the slide groove.

[0052] The slider 10c is horizontally slidably connected to the mounting frame 1. Specifically, a linear guide rail 10c1 can be arranged between the two. The slider 10c is driven by the rotation of the cam 9. That is, the slider 10c is fixedly provided with a second connecting column inserted into the guide groove, and the diameter of the second connecting column is equal to the width of the guide groove.

[0053] The two ends of the connecting rod 10b are respectively hinged to the connecting portion 10a and the slider 10c. That is, through the connecting rod 10b, the horizontal sliding of the slider 10c is converted into the up and down sliding of the connecting portion 10a, so that the cover plate 3 is opened and closed once by the rotation of the cam 9.

[0054] Furthermore, there are two cover plates 3, and the two cover plates 3 are symmetrically hinged at the first slit 2a of the housing 2. Compared with one cover plate 3, when there are two cover plates 3, the distance that the connection portion 10a needs to move downward to open the cover plate 3 is smaller, and accordingly, the distance that the slider 10c needs to slide is also smaller, and it is more convenient to set the guide groove and the cam 9.

[0055] First, the linkage assembly 10 has just passed the second circular arc portion 9b and is in the first circular arc portion 9a, and the cover plate 3 is in a state of blocking the first gap 2a; then, the suction device 6 sucks the feed, and the feed falls into the position close to the first side in the shell 2; then the motor 8 drives the feeding rod to rotate, and the belt cam 9 rotates at the same time, the linkage assembly 10 passes the first circular arc portion 9a, the cover plate 3 remains in a state of blocking the first gap 2a, and the feeding screw gradually transmits the feed to the second end in the shell 2; finally, the linkage assembly 10 enters the second circular arc portion 9b, and the cover plate 3 switches to a state of not blocking the first gap 2a. At this time, the feed has covered the cover plate 3 (the number of teeth on the worm can be determined according to the number of pitches 4b on the dragon blade 4a), and as the cover plate 3 opens, the feed falls from the discharge gap.

[0056] Optionally, a spacing portion 2c is reserved between the end surface of the second side of the shell 2 and the first gap 2a. Compared with not leaving this spacing portion 2c, when the cover plate 3 is switched to a state where the first gap 2a is not blocked, the feed can begin to enter this spacing under the action of the feeding rod, thereby better ensuring that the feed covers the cover plate 3. Correspondingly, the shell 2 is also provided with a discharge port 2c1 corresponding to the spacing portion 2c, and the discharge port 2c1 is used to discharge the feed in this spacing. The discharge port 2c1 is connected to the silo 5, that is, the feed in this spacing is recovered.

[0057] Further, the silo 5 is located at the first side of the mounting frame 1. Accordingly, a material guide pipe may be provided between the discharge port 2c1 and the silo 5.
