Description

Technical Field

[0001] The present invention relates to the technical field of breeding and planting, and in particular to a pneumatic feeding system for aquaculture. Background Art

[0002] There are many shortcomings in the traditional feeding methods of existing aquaculture technologies on the market. Among them, the inability to accurately and safely control the feeding range of feed at a long distance is an urgent problem to be solved. Feed feeding is an indispensable part of the aquaculture process. Scientific and reasonable feed feeding can significantly improve the conversion rate of feed and reduce waste, thereby reducing feeding costs and improving aquaculture benefits. By accurately controlling the feeding amount and feeding frequency, it can ensure that the aquaculture obtains sufficient nutrition, while avoiding feed waste and water quality deterioration caused by overfeeding.

[0003] In order to solve this problem, many feed feeding machine products have appeared on the market, such as centrifugal feeders, drop feeders, etc. However, there are some problems in the use process. For example, the traditional centrifugal feeder feed is easily affected by wind factors during the feed throwing process, resulting in uneven throwing, resulting in too much feed in one area and insufficient feed in another area. Drop feeders can usually only deliver feed to a short distance and cannot be used in large-scale breeding environments. In addition, their working noise is loud and the types of feeds are limited, making them unable to be used on a large scale.

[0004] Therefore, a new type of feeding system is urgently needed.

[0029] Next, the disclosed concept of the present disclosure will be described in detail with reference to the accompanying drawings. Described here are only preferred embodiments according to the present disclosure, and those skilled in the art may think of other ways to implement the present disclosure on the basis of the preferred embodiments, and the other ways also fall within the scope of the present disclosure. In the following specific description, directional terms such as "upper", "lower", "inner", "outer", "longitudinal", "horizontal", etc. are used with reference to the directions described in the accompanying drawings. The components of the embodiments of the present disclosure can be placed in a variety of different directions, and the directional terms are used for illustrative purposes and are not restrictive.

[0030] In the present disclosure, the feeding system 1 is suitable for occasions where materials (such as feed, seeds, etc.) need to be fed over a large area, and is particularly suitable for aquaculture operations.

[0031] Figure 1 The overall structure of the aquaculture pneumatic feeding system 1 is shown; Figure 2 The overall structure of the feeding mechanism 20 of the aquaculture pneumatic feeding system 1 is shown; Figure 3 The overall structure of the feeding mechanism 30 of the aquaculture pneumatic feeding system 1 is shown.

[0032] See also Figure 1-3 The aquaculture pneumatic feeding system 1 includes a power mechanism 10, a feeding mechanism 20 and a feeding mechanism 30, pipelines between the mechanisms 10, 20, 30, valves 13, 14, 15 on each section of the pipeline, and a control system not shown. The power mechanism 10 of the pneumatic feeding mechanism 30 in the present disclosure includes an air compressor 11 and a diverter 12 located at the outlet end of the air compressor 11. The power mechanism 10 provides high-pressure air to different downstream mechanisms 10, 20, 30 through the diverter 12 to provide power for them. Figure 1 In the example, the diverter 12 is provided with at least three air outlets to divert the high-pressure air into at least three paths. Specifically, the first outlet end of the diverter 12 provides power to the feeding mechanism 20 through the pneumatic motor air supply pipeline P1, the second outlet end provides power to the delivered material through the feeding pipeline P2, and the third outlet end provides power to the control mechanism (specifically the pneumatic cylinder 43, which will be described in detail below) of the feeding mechanism 30 through the pneumatic cylinder air supply pipeline P3.

[0033] Figure 1 , 2 The feeding mechanism 20 shown is configured to deliver materials to the downstream mechanism at a controlled speed. The feeding mechanism 20 is composed of a silo 21, a silo bracket 22, a pneumatic motor 23, a star-shaped discharge valve 24, etc. The silo 21 is a bucket-shaped structure that can hold a large amount of materials to be delivered. If necessary, the aquaculture pneumatic feeding system 1 can be provided with another feed pipeline (not shown) to the entrance of the silo 21 so as to continuously transport materials to the silo 21. The silo bracket 22 supports the silo 21 and other components of the feeding mechanism 20. In the present embodiment, the silo bracket 22 is mainly constructed by a rod-shaped support arm, a support plate, etc. through known methods such as welding and / or threading. It should be noted that the silo bracket 22 can also be any other bracket form that can be used for support, which will not be repeated here.

[0034] The power required by the pneumatic motor 23 is provided by the high-pressure air provided by the air compressor 11 through the pipeline P1. The pneumatic motor 23 drives the star-shaped blanking valve 24. The speed of the pneumatic motor 23 directly determines the amount of material dropped by the star-shaped blanking valve 24 each time. In the present application, the speed of the pneumatic motor 23 is controlled by the opening size of the pneumatic motor control valve 13 on the air supply pipeline of the pneumatic motor 23.

[0035] The material in the silo 21 enters the feeding pipeline P2 under the action of the star-shaped drop valve 24 driven by the pneumatic motor 23. The high-pressure air introduced from the diverter 12 pushes the material in the feeding pipeline P2 to the feeding mechanism 30. The feeding speed of the material in the feeding pipeline P2 and the feeding mechanism 30 can be controlled by controlling the valve opening of the feeding valve 14 in the feeding pipeline.

[0036] The feeding mechanism 30 receives the material from the feeding mechanism 20. The feeding mechanism 30 has an adjustable feeding port E. The feeding mechanism 30 adjusts the feeding direction and feeding range of the material through the feeding port E.

[0037] As described above, in the present application, each power unit is driven by high-pressure air. In particular, in the case of aquaculture, the feeding mechanism 30, which is relatively close to the water surface, does not have any electrical unit, which can avoid any electrical accidents and ensure the safety of the staff. In addition, the feeding pipeline P2 in the aquaculture pneumatic feeding system 1 of the present application can be increased or decreased in length as needed, which makes the aquaculture pneumatic feeding system 1 disclosed in the present application suitable for scenes with long feeding distances. The directionally adjustable delivery port E can ensure that the aquaculture pneumatic feeding system 1 accurately projects the delivery direction and range of the material.

[0038] Referring to the relevant drawings of the feeding mechanism 30 of 3-8, the feeding port E of the feeding mechanism 30 is defined by the outer blade group 31 and the inner blade group 32 which can be synchronously adjusted. The outer blade group 31 includes a plurality of outer blades 31A arranged in different circumferential directions and forming a first annular wall S1. The inner blade group 32 includes a plurality of inner blades 32A arranged in different circumferential directions and forming a second annular wall S2. The first annular wall S1 and the second annular wall S2 define the feeding port E into a trumpet shape.

[0039] See also Figure 3 Combined with Figure 4 , 8 The feeding mechanism 30 has a feeding machine housing 38 fixed to the end of the feeding pipeline P2. The feeding machine housing 38 is trumpet-shaped. The inside of the feeding machine housing 38 is provided with Figure 8 , 4 Visible feeder blade 36. Feeder blade 36 has blade shaft 36A. The feeder blade 36 is a spiral blade, and the spiral blade has a conical shape matching the feeder housing 38 in its axial section. The spiral blade 36 uniformly feeds the material to each circumferential inner wall of the feeder housing 38. Preferably, in the axial direction of the feeder blade 36, each outer edge of the spiral feeder blade 36 and the inner surface of the feeder housing 38 are set to have an equal distance, so as to facilitate the uniform distribution of equal amounts of material to be fed to each circumferential location of the feeder housing 38 through the feeder blade 36.

[0040] The feeding mechanism 30 has an independent supporting mechanism 40. Figure 3 In the feeding mechanism 30 shown, the support mechanism 40 is composed of a plurality of rod-shaped or plate-shaped support walls 41 which are overlapped and fixed to each other vertically and horizontally, and a support flat plate 42 located below the support mechanism. The support flat plate 42 is used to strengthen the overall structural strength of the support mechanism. The coverage area of ​​the support flat plate 42 should be staggered with the feeding direction of the feeding port E.

[0041] See also Figure 3-8 The upper end of each outer blade 31A of the outer blade group 31 is hingedly fixed to the feeder housing 38. The outer blade 31A can be optionally configured to be hingedly fixed to the lower end of the feeder housing 38. Figure 3-8 In the example, the upper end of the outer blade 31A is fixed to the lower end of the feeder housing 38 through a bearing. Under the support of only the lower end of the feeder housing 38, the outer blade 31A will naturally rotate around the feeder housing 38 to a vertical state under the action of gravity.

[0042] See also Figure 5 In order to improve the overall rigidity of the feeding mechanism 30, a support plate 37 is provided at the end of the feeding machine housing 38. The two ends of the support plate 37 are respectively fixed to the lower end of the blade shaft 36A of the above-mentioned feeding machine blade 36 and the end of the feeding machine housing 38. Optionally, the two ends of the support plate 37 are fixed by bearings 44 to provide a certain flexibility while ensuring the overall rigidity of the feeding mechanism 30, so as to avoid the vibration of the feeding mechanism 30 and the formation of stress at the two ends of the support plate 37.

[0043] The inner blade set 32 ​​is located inside the outer blade set 31. The synchronous adjustment of the inner blade set 32 ​​and the outer blade set 31 is performed by an adjustment assembly consisting of a telescopic rod 33, a first hinge rod 34, a second hinge rod 35, etc. Figure 4-8 The upper end of each inner blade 32A of the inner blade group 32 is hinged (for example, hinged by a bearing) and fixed to the lower end of the blade shaft 36A of the above-mentioned feeder blade 36. More specifically, the lower end of the blade shaft 36A is provided with a Figure 5-8 The disc-shaped tray 39 shown. The upper end of the inner blade 32A is hingedly fixed to the outer edge of the disc-shaped tray 39 by means of a bearing or the like.

[0044] See also Figure 4-8 The feeding mechanism 30 of each angle of view shows the telescopic rod 33, the first hinge rod 34, the second hinge rod 35, etc. of the above-mentioned direction adjustment component for adjusting the direction of the feeding port E. Among them, the two ends of the first hinge rod 34 are respectively hinged to the outer blade 31A and the telescopic rod 33 (the hinge point of the telescopic rod 33 is Figure 4The second hinge rod 35 is hinged to the outer blade 31A and the inner blade 32A at the same circumferential position. The telescopic rod 33 can actuate the first hinge rod 34 through telescopic movement, thereby synchronously adjusting the directions of the outer blade group 31 and the inner blade group 32.

[0045] The telescopic rod 33 is set below the second annular wall S2 defined by the inner blade set 32 ​​( Figure 5 The first hinge rod 34 passes through the inner blade 32A and hinges against the inner surface of the outer blade 31A ( Figure 7 , Figure 5-6 ). To this end, a clearance hole C is formed on the inner blade 32A for evading the first hinge rod 34. The clearance hole C should be in a long strip shape to ensure that the first hinge rod 34 can rotate freely during the adjustment process of the inner and outer blades 32A and 31A. The position where the first hinge rod 34 abuts against the outer blade 31A can be at a substantially middle position of the outer blade 31A in the blade length direction.

[0046] The hinge points between the two ends of the second hinge rod 35 and the outer blade 31A and the inner blade 32A may be optionally set to the lower end of the outer blade 31A and the lower end of the inner blade 32A, respectively.

[0047] See also Figure 5-8 When the telescopic rod 33 is actuated by the pneumatic cylinder 43 to move up and down, the telescopic rod 33 drives the first hinged rod 34 to move synchronously, thereby driving the outer blade 31A to expand outward or retract inward; the outer blade 31A drives the second hinged rod 35 hinged thereon to drive the inner blade 32A to expand outward or retract inward synchronously, completing the synchronous action.

[0048] The high-pressure air required by the pneumatic cylinder 43 to actuate the telescopic rod 33 is delivered by the pneumatic cylinder air supply pipeline P3 mentioned above. The telescopic length of the telescopic rod 33 is controlled by controlling the valve (pneumatic control valve 15) on the pneumatic cylinder air supply pipeline P3. When the opening of the valve 15 increases, the telescopic rod 33 extends upward, pushing the upper end of the first hinge rod 34 to move upward; conversely, when the valve opening decreases, the outer blade group 31 and the inner blade group 32 automatically fall down under their own gravity, forcing the telescopic rod 33 to retract.

[0049] See also Fig. 9 , which shows Figure 3-8The diagram is a simplified schematic diagram of the relative positional relationship between the blades 31A, 32A, the hinged rods 34, and 35 when the feeding port E in the feeding mechanism 30 is in different orientations. The outer blade 31A, the inner blade 32A, the first hinged rod 34, and the second hinged rod 35 in the same state are represented by the same lines. Point A corresponds to the hinge point on the disc tray 39 below the blade shaft 36A where the inner blade 32A abuts. Point B corresponds to the hinge point on the feeder housing 38 where the outer blade 31A abuts. Point D represents the contact point between the first hinged rod 34 and the telescopic rod 33. Fig. 9 As shown in the simplified diagram, the second hinged rod 35 can directly indicate the outlet position and outlet direction of the feeding port E. In the first state of the feeding mechanism 30 shown by the dotted line, the inner blade group 32 and the outer blade group 31 naturally droop by their own gravity, pressing the telescopic rod 33 to make it at the lowest position in the working stroke, and the feeding port E is closest to the center of the feeding machine housing 38. Fig. 9 In order to simplify and clearly express the positions of the components of the feeding mechanism in each state, and the changes of the components during the transformation of each state, only the hinge rods 34, 35 in the first state, and the inner and outer blades 31A, 32A are marked.

[0050] Continue to see Fig. 9 After the first state, with the pressurization of high-pressure air, the telescopic rod 33 moves upward for a certain distance, pushing one end of the first hinged rod 34 upward, and the feeding mechanism 30 changes to the second state shown by the dotted line composed of equal-length line segments. In the process of changing from the first state to the second state, the delivery port E gradually turns outward to ensure that the material is delivered to a more peripheral area. After the high-pressure air continues to drive the telescopic rod 33 to continue to extend upward through the pneumatic cylinder, one end of the first hinged rod 34 continues to move upward, and the feeding mechanism 30 changes to the third state shown by the solid line. In the third state, the delivery port E is oriented toward the outermost side, and the material is delivered to the outermost side.

[0051] It should be understood that the description of the movement process from the first state to the third state is only used to illustrate the mechanism of the delivery direction and delivery range of the delivery port E of the present application, and it does not mean that the state of the feeding mechanism 30 can only be adjusted in this order. Those skilled in the art can understand based on the disclosure of the present application that the state of the feeding mechanism 30 can be adjusted arbitrarily.

[0052] See also Figure 4As a preferred manner, during the adjustment process of the outer blade group 31, the adjacent outer blades 31A are always partially in contact with each other in the circumferential direction. In particular, the outer blades 31A of the outer blade group 31 are arranged in a manner of partially overlapping each other step by step in the circumferential direction. That is, one circumferential side of any outer blade 31A is partially covered by the outer blade 31A in front, and at the same time, the other circumferential side partially covers the adjacent outer blade 31A behind. In the above-mentioned "arranged in a manner of partially overlapping each other step by step in the circumferential direction" manner, fewer first hinge rods 34, or even only 1-2 first hinge rods 34, can actuate all outer blades 31A to unfold.

[0053] Similar to the case of the outer blade set 31, during the adjustment process of the inner blade set 32, the adjacent inner blades 32A always partially fit each other in the circumferential direction. In particular, the inner blades 32A of the inner blade set 32 ​​are arranged in a manner of partially overlapping each other step by step in the circumferential direction. In this case, even 1-2 second hinge rods 35 may be provided.

[0054] Preferably, the inner blades 32A and the outer blades 31A are arranged in pairs in the circumferential direction. The first hinged rods 34 and the second hinged rods 35 corresponding to the same pair of inner blades 32A and outer blades 31A are located at the same circumferential position. The plane defined by the paired first hinged rods 34 and the second hinged rods 35 and the axis of the blade shaft 36A and the central axis of the telescopic rod 33 can be defined to be coplanar with each other, which will facilitate the feeding system 1 to perform the expansion and contraction of the blades in a long-term and stable manner. At this time, the above-mentioned support plates 37 and the corresponding paired first hinged rods 34 and the second hinged rods 35 can be arranged on the same plane.

[0055] It should be noted that despite the above Figure 3-9 A specific form of the feeding mechanism 30 is described. However, according to the concept of the present application, those skilled in the art can make other forms of substitutions for the various components of the feeding mechanism 30. For example, the pneumatic cylinder 43 that drives the first hinged rod 34 is integrated into the blade shaft 36A. In addition, the hinge points of each hinged rod and the corresponding outer blade 31A and inner blade 32A can be adaptively adjusted according to the needs of different feeding ranges and feeding directions. In addition, each hinged rod 34, 35 can be fixed to the corresponding outer blade 31A and inner blade 32A through a slider mechanism. The hinged method in the form of a slider can ensure that while adjusting the feeding direction of the feeding port E, the opening size of the feeding port E is adjusted, and thus the material speed during feeding.

[0056] exist Figure 3-8 In the example, the upper end of the outer blade 31A is fixed to the feeder housing 38 to simplify the system. In addition, it can also be replaced by being fixed on other independent supporting structures.

[0057] According to the above contents of the present application, it can be known that the feeding mechanism 30 provided in the present application has a specific form of feeding port E, which allows the operator to adjust the feeding direction and feeding range of the feeding port E. Moreover, the direction adjustment control mechanism of the feeding port E used in the present application performs actions through high-pressure air, which ensures that the system involved in the present application is particularly suitable for occasions such as aquaculture where electrical accidents are prone to occur. In addition, the power source in the other main feeding system 1 of the disclosed system is high-pressure air, which is particularly suitable for occasions such as aquaculture where electrical accidents are prone to occur. In addition, the other main mechanisms in the feeding system 1 of the present application - the feeding mechanism 20, etc. are also controlled by high-pressure air, which reduces the use of the electrical system and ensures the safety of the system to the greatest extent.

[0058] The protection scope of the present disclosure is limited only by the claims. Thanks to the teachings of the present disclosure, those skilled in the art will easily recognize that alternative structures of the structures disclosed in the present disclosure can be used as feasible alternative embodiments, and the embodiments disclosed in the present disclosure can be combined to produce new embodiments, which also fall within the scope of the appended claims.
