DETAILED DESCRIPTION

[0023] The specific embodiments of the present disclosure will be described in detail below 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 used to limit the present disclosure.

[0024] In the present disclosure, the orientation words such as "inner" and "outer" used without the opposite description refer to "inner" and "outer" relative to the outline of the corresponding component itself. In addition, the terms "first", "second", and the like used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance. Furthermore, in the following description, the same reference numerals in different drawings represent the same or similar elements unless otherwise explained. The above definition is only used to explain and illustrate the present disclosure, and should not be understood as a limitation on the present disclosure.

[0025] The feeding device in the exemplary embodiment of the present disclosure will be described below in conjunction with the drawings.

[0026] Reference Figures 1 to 4 As shown in the drawings, the present disclosure provides a feeding device applied to a marine ranch, comprising a feeding frame 1, a storage box 2, a driving mechanism 3, a feeding box 4, and a transmission mechanism 5, wherein the storage box 2 can be arranged on the feeding frame 1 to provide bait; the driving mechanism 3 can be arranged on the feeding frame 1; the feeding box 4 is used for feeding bait, and the feeding box 4 is connected to the driving mechanism 3 to approach or move away from the storage box 2, the feeding box 4 comprises a feeding chamber 41 and a pushing mechanism 42, the feeding chamber 41 is used for storing the bait provided by the storage box 2, and the transmission mechanism 5 is arranged on the feeding frame 1 and connected to the pushing mechanism 42 to drive the pushing mechanism 42 to push the bait in the feeding chamber 41 out of the feeding chamber 41 during the process of the feeding box 4 approaching or moving away from the storage box 2.

[0027] Through the above technical solution, when feeding the marine ranch, the driving mechanism can first drive the feeding box 4 to approach the storage box 2 located on the feeding frame 1, and when the feeding box 4 is close enough to the storage box 2 or the two are connected, the storage box 2 can deliver the bait therein to the feeding chamber 41 of the feeding box 4 for temporary storage, and after receiving the bait, the feeding box 4 can move away from the storage box 2 and approach the feeding area of the marine ranch under the action of the driving mechanism, during which the transmission mechanism 5 can drive the pushing mechanism 42 to push the bait in the feeding chamber 41 out, thereby realizing the feeding operation. Based on this, the feeding device of the present disclosure can complete the feeding operation without even the participation of manual labor when performing the feeding operation, saving time and effort, and improving work efficiency.

[0028] Among them, the feeding area of the marine ranch can be located above the sea surface or at the bottom of the sea according to the type of marine organisms to be fed and the on-site environment.

[0029] In some embodiments of the present disclosure, as Figure 1As shown, the storage box 2 can be arranged on the top of the feeding frame 1, and the feeding box 4 can be arranged on the bottom of the feeding frame 1 and opposite to the storage box 2 in the height direction of the feeding frame 1, so that the storage box 2 can conveniently transfer the bait in the storage box 2 to the feeding box 4. For example, the feeding frame 1 can be provided with a through hole, and the storage box 2 can be tilted after being close to the feeding box 4, so that the bait in the storage box 2 can directly enter the feeding chamber 41 of the feeding box 4 through the through hole, and / or the storage box 2 can include a bait storage chamber 21 and a first communication pipe 22 in communication with the bait storage chamber 21, and the feeding box 4 can include a second communication pipe 43 connected with the first communication pipe 22 and in communication with the feeding chamber 41, so as to receive the bait in the bait storage chamber 21. The first communication pipe 22 and the second communication pipe 43 can be connected together by sleeving. For example, during the process that the driving mechanism drives the feeding box 4 to be close to the storage box 2, the second communication pipe 43 can be inserted into the first communication pipe 22, so as to realize the connection between the bait storage chamber 21 and the feeding chamber 41. Then, the staff can open the valve on the first communication pipe 22, so that the bait in the bait storage chamber 21 can enter the feeding chamber 41 through the first communication pipe 22 and the second communication pipe 43, thereby facilitating the subsequent feeding operation.

[0030] In some embodiments, as shown in Figure 3 and Figure 4 The feeding box 4 can include a first baffle 411 and a second baffle 412. The two first baffles 411 are arranged on the same inner side wall of the feeding box 4 having the discharge port 44. The second baffle 412 is movably arranged between the two first baffles 411 by a pushing mechanism 42, and the two ends of the second baffle 412 are respectively abutted with the two first baffles 411, so that the two first baffles 411, the second baffle 412 and the inner side wall of the feeding box 4 together form the feeding chamber 41 having an opening and being in communication with the storage box 2 through the opening. The opening can be located at the top of the feeding chamber 41. After the bait transported from the storage box 2 falls into the feeding chamber 41 from the opening, during the process that the driving mechanism drives the feeding box 4 to be away from the storage box 2, the transmission mechanism 5 can drive the pushing mechanism 42 to push the bait in the feeding chamber 41 out of the discharge port 44, thereby realizing the feeding operation of the bait.

[0031] As shown in Figures 1 to 3 The discharge port 44 can be configured with a plurality of discharge ports 44 arranged at intervals on the side wall of the feeding box 4. The plurality of discharge ports 44 can simultaneously discharge the bait in the feeding chamber 41, thereby improving the efficiency of bait feeding.

[0032] In addition, it should be noted that the discharge port 44 can be provided with a discharge pipe (not shown in the figure) with a valve. The valve on the discharge pipe can be opened when the bait feeding device feeds the bait, so that the bait can be discharged from the discharge pipe.

[0033] In addition, the second baffle 412 can abut against the two first baffles 411 at the movable limit positions, thereby ensuring that the bait in the bait delivery chamber 41 cannot leak out.

[0034] In some embodiments of the present disclosure, as shown in Figure 3 The pushing mechanism 42 can include a cam structure 421 and a pushing piece 422. The transmission mechanism 5 is connected to the cam structure 421 and can drive the cam structure 421 to rotate to directly or indirectly abut against the second baffle 412. The pushing piece 422 includes a first push rod 4221, one end of which is connected to the second baffle 412 and the other end of which is used to abut against the cam structure 421. In addition, the pushing piece 422 includes a second push rod 4222, which is arranged in the bait delivery chamber 41 in a telescopic manner, one end of the second push rod 4222 is connected to the inner side wall of the bait delivery box 4, and the other end of the second push rod 4222 abuts against the second baffle 412. That is, the pushing mechanism 42 can be connected to the bait delivery chamber 41 in various ways. For example, the pushing mechanism 42 can include the cam structure 421 and the first push rod 4221. The cam structure 421 can include a base circle region and a convex region that protrudes outward. In this way, the cam structure 421 can indirectly abut against the second baffle 412 through the first push rod 4221. Specifically, during the process in which the bait delivery box 4 receives the bait in the bait storage box 2 and moves away from the bait storage box 2, the transmission mechanism 5 drives the cam structure 421 to rotate, so that the convex region of the cam structure 421 can abut against the first push rod 4221. The first push rod 4221 is connected to the second baffle 412, so the convex region pushes the first push rod 4221 to one side of the bait delivery chamber 41, thereby driving the second baffle 412 to push the bait in the bait delivery chamber 41, so as to push the bait out of the bait delivery chamber 41. Since the bait cannot be completely discharged from the bait delivery chamber 41 at one time, when the base circle region of the cam structure 421 is located on the side of the first push rod 4221, the second baffle 412 can abut against the base circle region under the counter-pressing action of the bait remaining in the bait delivery chamber 41. Until the convex region again abuts against the first push rod 4221, the above-mentioned pushing step is repeated, so as to discharge the bait in the bait delivery chamber 41 as much as possible, thereby achieving the bait feeding operation. In addition, when a new round of bait feeding operation is performed, after the bait storage box 2 inputs the bait into the bait delivery chamber 41, the bait can also push the second baffle 412 to move to the side of the cam structure 421, so as to facilitate the subsequent bait feeding operation. In this arrangement, in order to facilitate the transmission of force between the cam structure 421 and the first push rod 4221, the first push rod 4221 can be configured as a spring rod.

[0035] Alternatively, the pushing mechanism 42 may include a cam structure 421 and a second push rod 4222. In this case, the cam structure 421 can directly abut against the second baffle 412, and the retractable second push rod 4222 can be configured as a spring rod. Specifically, during the process of the feeding box 4 receiving bait from the storage box 2 and moving away from the storage box 2, the transmission mechanism 5 will drive the cam structure 421 to rotate, so that the protruding area of ​​the cam structure can abut against the second baffle 412, thereby pushing the second baffle 412 to push the bait in the feeding chamber 41. The bait is fed out of the feeding chamber 41. During this process, the second push rod 4222 is compressed. When the base circle area of ​​the cam structure 421 faces the second baffle 412, the second push rod 4222 will return to its initial state under the action of the spring, thereby pushing the second baffle 412 towards the cam structure 421 so that the protruding area of ​​the cam structure 421 abuts against the second baffle 412 again. The above pushing steps are repeated to discharge as much bait as possible from the feeding chamber 41, thus realizing the feeding operation.

[0036] Or, for example Figure 4 As shown, the pushing mechanism 42 may include a cam structure 421, a first push rod 4221, and a second push rod 4222. Specifically, during the process of the feeding box 4 receiving bait from the storage box 2 and moving away from the storage box 2, the transmission mechanism 5 will drive the cam structure 421 to rotate, so that the protruding area of ​​the cam structure 421 can abut against the first push rod 4221. The first push rod 4221 will push the second baffle 412 to push the bait in the feeding chamber 41. During this process, the second push rod 4222 will be compressed. When the base circle area of ​​the cam structure 421 faces the second baffle 412, the second push rod 4222 will return to its initial state under the action of the spring, thereby pushing the second baffle 412 to move towards the cam structure 421, so that the protruding area of ​​the cam structure 421 abuts against the first push rod 4221 again, thereby discharging the bait in the feeding chamber 41 as much as possible and realizing the feeding operation.

[0037] To further improve feeding efficiency, such as Figure 3 As shown, the feeding box can be equipped with multiple feeding chambers 41 and multiple pushing members 422, and the multiple feeding chambers 41 are arranged in a one-to-one correspondence with the multiple pushing members 422. Specifically, when the feeding box 4 is constructed as a rectangular box, the feeding chambers 41 and the pushing members 422 can both be configured with four. The four feeding chambers 41 can be located on the four sides of the feeding box 4, and the four pushing members 422 are arranged in a one-to-one correspondence with the four feeding chambers 41. The cam structure 421 can be set in the central area inside the feeding box 4, so that the cam structure 421 can abut against the second baffles 412 of the four pushing members 422 or the four feeding chambers 41 in sequence during the rotation process, thereby enabling the feeding box 4 to feed more bait and improve feeding efficiency.

[0038] In some embodiments of the present disclosure, as shown in Figure 1 and Figure 2 The transmission mechanism can include a transmission part 51, a first matching part 52 and a second matching part 53. The first matching part 52 is arranged on the feeding frame 1 and extends along the moving direction of the feeding box 4. The second matching part 53 is arranged in the feeding box 4 and connected with the cam structure 421. One end of the transmission part 51 is engaged with the second matching part 53, and the other end can be engaged with at least part of the first matching part 52 during the movement of the feeding box 4 to drive the cam structure 421 to rotate. That is, during the movement of the feeding box 4, the transmission mechanism 5 and the feeding box 4 can drive the pushing mechanism 42 in the feeding box 4 to work through mechanical transmission, without the need to set other electric structures to achieve the effect of pushing the bait out of the feeding box 4, saving the cost of the feeding device.

[0039] Specifically, as shown in Figure 1 and Figure 2 The first matching part 52 can include a connecting rod 521 arranged on the feeding frame 1 and a rack 522 arranged on the connecting rod 521. The transmission part 51 includes a transmission rod 511 and a gear 512 and a first bevel gear 513 arranged at both ends of the transmission rod 511 respectively. The gear 512 can be engaged with the rack 522. The second matching part 53 includes a second bevel gear 531 connected with the cam structure 421 and engaged with the first bevel gear 513. The rack 522 can be engaged with the gear 512 during the approach or departure of the feeding box 4 to the bait storage box 2, or the rack 522 can be engaged with the gear 512 during the departure of the feeding box 4 from the bait storage box 2.

[0040] For example, the rack 522 can be arranged on the part of the connecting rod 521 away from the feeding frame 1. In this way, the gear 512 on the feeding box 4 can be between the rack 522 and the feeding frame 1 in the non-working state, and the gear 512 and the rack 522 are not engaged. When the feeding operation is needed, the driving mechanism first drives the feeding box 4 to move towards the side of the bait storage box 2, i.e. the gear 512 moves towards the side of the feeding frame 1. At this time, the gear 512 and the rack 522 are still not engaged, and the feeding box 4 will not feed the bait outward. After the feeding box 4 receives the bait, the driving mechanism drives the feeding box 4 to move reversely, i.e. the gear 512 moves towards the side of the rack 522, until the gear 512 and the rack 522 are engaged. The gear 512 rotates, thereby driving the transmission rod 511 and the first bevel gear 513 connected therewith to rotate. Since the first bevel gear 513 and the second bevel gear 531 are engaged, the second bevel gear 531 also drives the cam structure 421 to rotate under the driving of the first bevel gear 513, so as to realize the feeding operation.

[0041] In some unillustrated embodiments, the driving mechanism can also be configured as a pneumatic cylinder, which can be connected with the bottom of the feeding frame 1 and the output end of which is connected with the feeding box 4, so that the position of the feeding box 4 can be adjusted.

[0042] In the embodiments of the present disclosure, as shown in Figures 1 to 3 The outer side wall of the feeding box 4 can be provided with a camera 6, which can monitor the situation in the marine ranching when the feeding box 4 is feeding. In addition, the camera 6 can be provided with a plurality of cameras 6, which are respectively arranged on different outer side walls of the feeding box 4, so that the camera can monitor the marine ranching in all directions.

[0043] The preferred embodiments of the present disclosure are described in detail above in combination with the drawings, but the present disclosure is not limited to the specific details in the above-described embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0044] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, various possible combinations are not described again in the present disclosure.

[0045] In addition, various different embodiments of the present disclosure can also be combined in any manner, as long as it does not deviate from the idea of the present disclosure, and it should also be considered as disclosed in the present disclosure.
