Description

Technical Field

[0001] The utility model relates to the technical field of feed throwing, in particular to a feed throwing device for freshwater sea bass breeding. Background Art

[0002] Sea bass is a popular fish with a variety of varieties and rich nutritional value. In order to meet market demand and support the development of the aquaculture economy, major farms are breeding sea bass on a large scale. During the breeding process, sea bass usually uses feed spreading devices to automatically feed the sea bass in a quantitative manner, helping to maintain optimal breeding conditions, thereby improving the growth rate of the fish and overall production efficiency.

[0003] Chinese patent application number CN218789868U discloses a feed spreading device for fish pond farming. The device comprises a placement plate and a motor housing. The placement plate is provided with a support plate on its surface. An electro-hydraulic push rod is mounted on one side of the support plate. The output end of the electro-hydraulic push rod is connected to a feed drum. A second motor is mounted at the bottom of the motor housing. The output end of the second motor is connected to a second rotating shaft. The second motor drives a curved paddle plate to rotate via the second rotating shaft, causing the curved paddle plate to disperse feed that has fallen onto the placement plate surface, thereby spreading it within the fish pond.

[0004] However, the aforementioned feed spreading device uses a circular spreading method, requiring an electric push rod to position the device in the middle of the pond for spreading. The electric push rod and its control system increase the manufacturing cost of the equipment and increase the complexity and difficulty of installation and movement. In large ponds, each installation and movement can consume a lot of time and manpower. Utility Model Content

DETAILED DESCRIPTION

[0022] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0023] Example 1

[0024] like Figure 1-Figure 3 As shown, the utility model proposes a feed spreading device for freshwater sea bass farming, including a base 1, an air pump 8 and a connecting mechanism. The base 1 is provided with a pillar 2, and a material box 3 is provided on the pillar 2. The bottom of the material box 3 is connected with a feed pipe 4, and a conveying cylinder 5 is provided at the bottom of the feed pipe 4. A conveying assembly is provided inside the conveying cylinder 5, and a feed discharge pipe 6 is rotatably connected to the bottom, and a spreading pipe 7 is connected to the bottom end of the feed discharge pipe 6. An air pump 8 is installed on the base 1, and the air outlet end of the air pump 8 is connected with an air hose 9, and one end of the air hose 9 is connected to the spreading pipe 7. A connecting mechanism is provided at one end of the conveying cylinder 5, which cooperates with the conveying assembly to drive the feed discharge pipe 6 to rotate back and forth to change the feed spreading direction.

[0025] like Figure 2 As shown, the four corners of the bottom of the base 1 are connected to rollers 10, and one end of the top is connected to a handle 11. The cooperation between the handle 11 and the roller 10 improves the convenience of moving the base 1.

[0026] like Figure 2 As shown, the spreading pipe 7 is set obliquely, one end of its top is set as an open structure, and the other end of its bottom is set as a closed structure. The air supply hose 9 runs through the closed end to the inside of the spreading pipe 7. Through the obliquely set spreading pipe 7, the feed is thrown obliquely upward under the action of the airflow.

[0027] like Figure 3 As shown, the conveying assembly includes a motor 12, a conveying shaft 13 and a spiral blade 14. The motor 12 is installed at one end of the conveying cylinder 5, and its output end passes through the conveying cylinder 5 and is connected to the conveying shaft 13. The outer side of the conveying shaft 13 is provided with a spiral blade 14.

[0028] When the device needs to be used, the entire device is moved to the edge of the pond or the feeding platform through the roller 10 and the handle 11, and then the motor 12 is started. The feed box 3 falls into the conveying cylinder 5 along the conveying pipe 4, and the motor 12 drives the conveying shaft 13 and the spiral blade 14 to rotate, thereby evenly conveying the feed to the discharge pipe 6 and falling into the throwing pipe 7, and under the action of the airflow of the air pump 8, it is thrown obliquely upward along the throwing pipe 7.

[0029] Example 2

[0030] like Figure 1-Figure 3 As shown, the present invention proposes a feed spreading device for freshwater sea bass farming. Based on the above embodiment, this embodiment also records in detail the specific components of the connecting mechanism and its effect on the feed pipe 6.

[0031] like Figure 2 As shown, the connecting mechanism includes a horizontal shaft 15, a main bevel gear 16, a slave bevel gear 17, a vertical shaft 18, a connecting plate 19, a cam 20 and a matching piece. The end of the conveying shaft 13 facing away from the motor 12 is connected to the horizontal shaft 15, and one end of the horizontal shaft 15 passes through the conveying cylinder 5 and is connected to the main bevel gear 16, and one side of the main bevel gear 16 is meshed and connected to the slave bevel gear 17; a support plate 24 is provided at one end of the conveying cylinder 5 and is located below the horizontal shaft 15. A vertical shaft 18 is rotated and passes through the support plate 24. The top of the vertical shaft 18 is connected to the slave bevel gear 17, and the bottom end of the vertical shaft 18 is connected to the connecting plate 19. A cam 20 is provided at the eccentric point of the lower end surface of the connecting plate 19. The matching piece is installed on the discharge pipe 6, and it cooperates with the cam 20 to drive the discharge pipe 6.

[0032] like Figure 3 As shown, the fitting includes a connecting ring 21 and a strip plate 22. The connecting ring 21 is arranged on the outside of the discharge pipe 6, and one side of the connecting ring is connected to the strip plate 22. The strip plate 22 is provided with a slot 23 for the cam 20 to pass through.

[0033] When the feed is being transported in the conveying cylinder 5, the conveying shaft 13 will drive the horizontal shaft 15 to rotate synchronously, and the horizontal shaft 15 will drive the main bevel gear 16 at its end to rotate. The main bevel gear 16 is engaged with the slave bevel gear 17. Under the action of the meshing force, the vertical shaft 18 will rotate, thereby driving the connecting disk 19 at its bottom to rotate. When the connecting disk 19 rotates, it will drive the cam 20 below it to move along a circular trajectory. During the movement, the cam 20 pushes the strip plate 22, so that the strip plate 22 drives the discharge pipe 6 to rotate back and forth within a certain range through the connecting ring 21. During the rotation, it drives the spreading pipe 7 to rotate synchronously, thereby expanding the spreading range and improving the uniformity of feeding within the range.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
