Description

Technical Field

[0002] With increasing domestic consumer demand for seafood, marine aquaculture in coastal areas is moving towards mechanization and automation, with a strong push towards pasture-based marine aquaculture. The continued expansion of aquaculture scale and the resulting increase in labor costs necessitate automated bait delivery equipment to reduce labor intensity and save on aquaculture inputs. Air jet delivery of solid granular bait can cause excessive abrasion of the bait, resulting in fine bait powder that cannot be eaten by fish, leading to waste and increased aquaculture costs. Water pumping also causes excessive abrasion and loss of the bait due to the high-speed agitation of the impeller after solid granular bait enters the pump. The solid bait passing through the pump also causes wear on the high-speed rotating components. Summary of the Invention

[0029] To further illustrate various embodiments, the present invention provides accompanying drawings. These drawings form part of the present disclosure and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will be able to understand other possible implementations and the advantages of the present invention.

[0030] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0031] An embodiment of the present invention provides a solid granular bait delivery device, which comprises a rotor composed of a plurality of cavities located at the vertices of a regular polygon. The rotor is controlled by a servo motor to rotate counterclockwise for a fixed angle (360 degrees divided by the number of cavities) each time the rotor rotates according to the set bait delivery time or the set delivery amount as a signal to trigger the rotor rotation, and the rotor stops rotating after each rotation, and the timing of the next bait delivery or the delivery metering is performed. The cavities should include at least three, and the rotor is rotated intermittently in sequence so that all cavities perform the following tasks in each working cycle: one cavity is in the solid-liquid mixing position of the bait, at which time the solid granular bait in the cavity is continuously discharged and transported along with the seawater and freshwater pumped into the device; one cavity is in the water discharge position, at which time the seawater and freshwater in the cavity are partially discharged to prepare for the filling of solid granular bait; and one cavity is in the feeding position, at which time solid granular bait is added to the cavity.

[0032] Furthermore, a cavity filled with bait can be added and placed in a waiting position, which will be transferred to the solid-liquid mixing position in the next working cycle.

[0033] Furthermore, in order to increase the delivery efficiency, more than one cavity tube can be provided at the solid-liquid mixing position of the bait, and the solid granular bait can be simultaneously delivered to the bait delivery pipeline through the more than one cavity tube.

[0034] In this embodiment, five lumens are used as an example for description. Specifically, the main components of the device include a motor, a shaft, five lumens, an upper sealing plate, a lower sealing plate, an upper cover plate and a lower cover plate.

[0035] One end of the five lumens is fixedly connected to the upper sealing plate, and the other end is fixedly connected to the lower sealing plate. The five lumens are evenly arranged on a circle with the center of the upper sealing plate or the lower sealing plate as the center. Through holes are provided on the upper sealing plate and the lower sealing plate at corresponding positions connecting the five lumens.

[0036] The upper cover plate is arranged on the side of the upper sealing plate away from the cavity tube, and the lower cover plate is arranged on the side of the lower sealing plate away from the cavity tube; the centers of the upper cover plate, the lower cover plate, the upper sealing plate and the lower sealing plate are on the same axis, and the shaft passes through the upper cover plate, the lower cover plate, the upper sealing plate and the lower sealing plate at the same time from the axis, and is fixedly connected to the upper sealing plate and the lower sealing plate, and movably connected to the upper cover plate and the lower cover plate; the motor is used to control the rotation of the shaft.

[0037] The upper cover plate is provided with four through holes at positions corresponding to four of the five through holes of the upper sealing plate, which are, in order: a feeding port, an air vent and two water outlets. The feeding port is used to feed solid granular bait, the air vent is connected to the air, and the water outlet is connected to the bait delivery pipe.

[0038] The lower cover plate is provided with three through holes at positions corresponding to three adjacent through holes of the five through holes of the lower sealing plate, namely: two water inlets and one water drain.

[0039] The upper cover plate is fixedly connected to the lower cover plate, the two water outlets of the upper cover plate correspond to the positions of the two water inlets of the lower cover plate, and the air vent of the upper cover plate corresponds to the position of the drain port of the lower cover plate.

[0040] In this embodiment, the device is first composed of a shaft, five cavities, an upper sealing plate and a lower sealing plate to form a rotor assembly, and then the upper cover plate and the lower cover plate are combined to form a device assembly. The positions of the five cavities and the shaft are arranged as follows: Figure 1 As shown, Figure 1 1-5 are the positions of the five lumens, and 30 is the position of the axis.

[0041] like Figure 2 As shown, the operating principle of this embodiment of the apparatus is as follows: the solid-liquid mixing device uses a servo motor to drive the rotor assembly, which starts and stops rotating according to a set value, causing the five chambers to sequentially occupy different working positions. During intermittent cyclic operation, seawater or freshwater pumps 6 deliver seawater or freshwater from a water source 28 to the solid-liquid mixing device via a water inlet pipe 29. Water enters the rotor assembly's chambers 1 and 2 through the water inlet 8 of the lower cover plate 9, pushing the solid granular bait in these chambers through the water outlet 15 of the upper cover plate 12 and the bait delivery pipe 13 to the aquaculture farm 14. Meanwhile, the water in the rotor assembly's chamber 3 is discharged from the drain hole 26 through the valve 27 to the water source 28. Simultaneously, solid granular bait is added to the chamber 4 through the feeding port 17 via the frustum-shaped orifice 18. The already filled chamber 5 is then placed in a waiting state, awaiting the next operating cycle. The frustum-shaped orifice facilitates the flow and discharge of the solid granular bait.

[0042] When two of the five lumens are in positions 1 and 2, seawater and freshwater pumped by water pump 6 flow through the water inlet 8 of the lower cover plate 9, the cylindrical opening 25 of the lower sealing plate 10, lumens 1, 2, the frustum-shaped opening 18 of the upper sealing plate 11, and the water outlet 15 of the upper cover plate 12, carrying away the solid granular bait in the lumens and delivering it to the breeding farm 14 through the bait delivery pipe 13. When the lumens are in position 3, the chamber is connected to the air vent 16 of the upper cover plate 12 through the frustum-shaped opening 18 of the upper sealing plate 11, and to the drain hole 26 of the lower cover plate 9 through the cylindrical opening 25 of the lower sealing plate 10. At this time, lumens 3 is draining. When the lumens are in position 4, lumens 4 is connected to the feeding hole 17 of the upper cover plate 12 through the frustum-shaped opening 18 of the upper sealing plate 11, through which the solid granular bait is added. When the lumen is located at position 5, there are no through holes between the upper cover plate 12 and the lower cover plate 9, and the lumen 5 is in a closed waiting state.

[0043] In the sealing between the upper and lower sealing plates and the upper and lower cover plates, this embodiment adopts a special-shaped sealing ring combined with an inner and outer sealing ring to solve the water sealing between the upper and lower sealing plates and the upper and lower cover plates. Figure 3 and Figure 4 As shown, a cylindrical groove is provided on the side of the upper cover plate 12 near the upper sealing plate. The upper sealing plate is placed in the cylindrical groove. The circumferential surface of the upper cover plate 12 and the circumferential surface 121 of the cylindrical groove are sealed by a first sealing ring, and the end surface of the upper cover plate 12 and the bottom surface 122 of the cylindrical groove are sealed by a second sealing ring. In this embodiment, the first sealing ring includes two, an inner sealing ring and an outer sealing ring, respectively. The second sealing ring is a special-shaped sealing ring set based on the shape of the bottom surface of the cylindrical groove. The structure of the special-shaped sealing ring in this embodiment is as shown in FIG. Figure 5 The sealing method between the lower cover plate 9 and the lower sealing plate 10 is the same as that between the upper cover plate 12 and the upper sealing plate 11, and will not be described in detail here. The use of special-shaped sealing rings can achieve independent effective working ranges.

[0044] In order to ensure that the water sealing effect of the upper and lower special-shaped sealing rings is good and the sealing rubber ring is not overly compressed, while at the same time extending the service life of the rubber ring and reducing the torque driving the rotor to rotate, the embodiment adopts a technology that combines the distance tube 22 with the adjustment of the lower bearing positioning to achieve (such as Figure 6 During assembly, the length of the spacer tube 22 ensures proper compression of the profiled seal ring, preventing it from being too tight or too loose. Therefore, adjustment can be made by stacking a thin shim (not shown) over the spacer tube. The position of the bearing adjustment seat is then adjusted by tightening the adjustment bolt 32. This allows the rotor assembly to slightly move upward relative to the device assembly, ensuring proper compression of the upper and lower profiled seal rings. This prevents the lower profiled seal ring from bearing the weight of the rotor assembly and being overly compressed, which could affect its service life and increase the torque required to drive the rotor.

[0045] The sealing blocks 24 are used to seal the upper and lower sealing plates and the cavity tube. The connecting blocks are used to connect the shaft to the upper and lower sealing plates. The upper and lower connecting blocks are fixedly connected to the upper and lower sealing plates respectively and connected to the shaft using a key.

[0046] The upper cover plate 12 is provided with a water distribution groove 123 (such as Figure 3(as shown); a water distribution trough 123 is provided on the side of the lower cover plate 9 near the lower sealing plate 10, connecting the two water inlets 8. The provision of water distribution trough 123 ensures that when one lumen rotates out of the water distribution trough's working area, another lumen rotates into the water distribution trough area, thereby reducing fluctuations in flow and pressure within the pumping piping system. In addition, this embodiment also provides isolation zones 124 on the periphery (on both sides) of water distribution trough 123 to prevent water from leaking from the water distribution trough area to other working areas during the rotation of the rotor assembly.

[0047] In this embodiment, when a servo motor 31 is used to drive the rotor assembly (shaft 30) to rotate, a solid particle bait filling amount setting value or a filling time setting value is used as a starting signal to trigger the rotation of the rotor assembly, and each rotation of 72 degrees is used as a trigger to stop the rotation, which is a control method for intermittently filling and delivering bait.

[0048] The embodiments of the present invention have the following beneficial effects:

[0049] 1. It is a core link in realizing the mechanized delivery of solid granular bait, which is used to realize mechanized operation to replace manual operation, saving labor and labor costs.

[0050] 2. Adding solid granular bait into the pump's output pipe can minimize the waste of bait caused by excessive stirring and friction during the transportation process, which may lead to granular powderization or excessive dissolution.

[0051] 3. It is convenient to carry out various control strategies to realize the control of bait feeding amount and to deliver bait at regular and quantitative times.

[0052] Although the present invention has been particularly shown and described in conjunction with preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims, and all such changes are within the scope of protection of the present invention.
