Description

Technical Field

[0001] The invention relates to the technical field of bait conveying equipment, in particular to an aquaculture bait conveyor. Background Art

[0002] Aquaculture refers to the use of seawater and freshwater to cultivate aquatic organisms, using aquaculture techniques and facilities to cultivate aquatic animals and plants in accordance with the ecological habits of the cultured organisms and the requirements for aquatic environmental conditions.

[0003] In particular, my country has rich marine and inland water resources, which has created inherent favorable conditions for the development of the aquaculture industry. In addition, the people's living standards have greatly improved, and the consumption demand for aquatic products has become increasingly higher, providing a good development environment for the aquaculture industry.

[0004] However, despite the good prospects of aquaculture, most aquaculture operations are still completed by the traditional way of carrying and shouldering, and the labor cost is extremely high. Aquatic creatures need to be fed artificially regardless of bad weather or at night. Many migrant workers cannot swim, and drowning safety stories often occur, which poses a great safety hazard. At the same time, manual feeding is to pour the bait into the sea at one time. The fish eat while the bait sinks, and the utilization rate is less than half. On the one hand, this causes a lot of waste, and on the other hand, the bait flows into the sea to mold, rot, pollute the seawater, and destroy the marine ecological environment. Therefore, in order to change the current production status of backward production capacity and reduce the risks of aquaculture operations, to maximize the production efficiency and sustainable development of the aquaculture industry, it is urgently necessary to invent an aquaculture bait conveyor to solve the current situation. Summary of the invention

[0005] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or be understood by implementing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the description and other drawings of the description.

[0006] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide an aquaculture bait conveyor. Through the circulating oil circuit block and the hydraulic oil tank, the first high-pressure oil cylinder and the second oil cylinder form a negative pressure suction high-pressure conveying mode, forming repeated alternating suction and delivery of the aquaculture bait.

Beneficial Effects

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention uses a circulating oil block and a hydraulic oil tank to form a negative pressure suction high pressure delivery mode for the first high pressure oil cylinder and the second oil cylinder, which replaces manual operation, forms repeated alternating work of sucking and delivering aquaculture bait, and at the same time, the bait is sprayed out from the spray pipe under the thrust of the delivered air pressure, and finally guided into the aquaculture frame from the guide pipe, effectively avoiding the potential safety hazards to the operator caused by water operations.

[0019] 2. The present invention can use a conveyor to set a good pressure value to transport bait, and transport and release bait according to the amount and size of fish in the aquaculture fish frame. At the same time, the bait is squeezed out of the pipe under the thrust and the reduction of the diversion pipe, making the bait more viscous and making the bait float on the water surface. While avoiding excessive bait feeding, it prevents the fish bait from sinking to the bottom of the sea and causing marine pollution problems.

[0020] 3. The present invention improves productivity through mechanized operation. Previously, six workers completed the workload, but now only one conveyor is needed. This not only solves the high labor cost and the difficulty of hiring workers, but also reduces production costs. Second, the feeding is controlled by the machine, which saves time, materials and waste. It solves the problem that the bait is poured into the sea at one time by manual feeding. The fish eats while the bait sinks, and the utilization rate is less than half. On the one hand, it causes a lot of waste. On the other hand, the bait flows into the sea to mold, rot, pollute the seawater, and destroy the marine ecological environment. The conveyor can control the feeding on demand, which is wasteful and pollution-free. Third, because it replaces the workers' hand-carrying and shoulder-carrying feeding at night, it can greatly avoid the safety incidents of drowning during manual operation. Fourth, it solves the problem that the majority of farmers have long used small-scale production methods with low technical content, high cost and low benefits. It can be scaled, industrialized and specialized, which greatly promotes the increase in production and income of farmers in the aquaculture industry, and will also greatly drive the development of the coastal economy.

[0036] As attached Figure 1 To Attachment Figure 4 As shown: Figure 1 This is a schematic structural diagram of an aquaculture bait conveyor according to the present invention; Figure 2 It is a schematic diagram of the top view of the structure of a mechanical steering valve in an aquaculture bait conveyor of the present invention; Figure 3 It is a schematic diagram of the three-dimensional structure of a converter in an aquaculture bait conveyor of the present invention; Figure 4 The present invention is a schematic diagram of the internal structure of a converter in an aquaculture bait conveyor.

[0037] The present embodiment provides an aquaculture bait conveyor, an aquaculture bait conveyor, comprising a base 1, an inlet and outlet assembly 2 is installed next to the base 1, a circulating cooler 3 is installed on the base 1, a three-way high-pressure ball valve 4 is installed on the base 1, a hydraulic oil tank 8 is installed on the base 1, a plurality of reversing high-pressure oil pipes 9 are arranged on the hydraulic oil tank 8, a cooling water tank 5 is fixed in the base 1, a circulating oil circuit block 13 is arranged above the cooling water tank 5, a mechanical steering valve 6 is installed on the circulating oil circuit block 13, an oil drain valve 7 is arranged next to the mechanical steering valve 6, and a mechanical cross is installed next to the oil drain valve 7. A pressure gauge 11 is installed on the oil drain valve 7, a one-way valve 12 is arranged on the oil drain valve 7, a first high-pressure oil cylinder 14 is installed in the base 1, a second oil cylinder 15 is arranged next to the first high-pressure oil cylinder 14, a converter 16 is arranged between the first high-pressure oil cylinder 14 and the second oil cylinder 15, and a material injection pipe 17 is connected to the converter 16; a linkage pendulum block 163 is arranged in the converter 16, telescopic push rods 162 are respectively installed on both sides of the linkage pendulum block 163, a connecting block 161 is connected to the end of the telescopic push rod 162, and a plurality of energy supply pipes 164 are installed on the telescopic push rod 162.

[0038] The specific working principle is as follows:

[0039] The equipment is used by an external diesel engine, and the feed inlet and outlet assembly 2 on one side of the base 1 controls the bait. Under the drive of the external equipment, the hydraulic oil tank 8 repeatedly operates the first high-pressure oil cylinder 14 and the second oil cylinder 15 through the reversing high-pressure oil pipe 9, forming a negative pressure suction high-pressure delivery mode working state. When the first high-pressure oil cylinder 14 inhales, the second oil cylinder 15 delivers outwards. The two repeatedly operate to inhale and discharge the bait in the feed inlet and outlet assembly 2. At the same time, the pendulum block 163 is pushed by the telescopic push rod 162 connected to the connecting block 161 under the energy supply of the energy supply pipe 164, so that its spray pipe 17 is in the state of discharging the bait. The docking guidance is carried out, and the mechanical exchange valve 10 mainly changes the position of the first high-pressure oil cylinder 14 and the second oil cylinder 15 during operation. The circulating oil circuit block 13 controls the distribution of the hydraulic oil. The one-way valve 12 prevents oil leakage. The oil in operation will also circulate along the three-way high-pressure ball valve 4 when repeated, and enter the circulating cooler 3 to cool the hydraulic oil. The cooling water tank 5 on the lower base 1 collects the condensed water generated by the circulating cooler 3. In order to ensure that the delivery amount of aquaculture bait is controlled, the installed pressure gauge 11 displays its suction and the pressure during delivery, so that the bait delivery amount can be observed accordingly.

[0040] As attached Figure 5 To Attachment Figure 8 As shown: Figure 5 It is a three-dimensional structural schematic diagram of a feeding and discharging assembly in an aquaculture bait conveyor of the present invention; Figure 6 It is a bottom view structural schematic diagram of a feeding device in an aquaculture bait conveyor of the present invention; Figure 7 It is a schematic diagram of the three-dimensional structure of a discharging device in an aquaculture bait conveyor of the present invention; Figure 8 The present invention is a schematic diagram of the three-dimensional structure of a material storage device in an aquaculture bait conveyor.

[0041] Among them, a discharging device 21 is arranged in the inlet and outlet assembly 2, a storage device 22 is connected below the discharging device 21, a feeding device 23 is connected below the storage device 22, a plurality of sealing devices 24 are arranged between the discharging device 21 and the storage device 22, and the plurality of sealing devices 24 are installed between the storage device 22 and the feeding device 23; a connecting plate 211 is arranged on the discharging device 21, a plurality of material guide barrels 212 are installed on the connecting plate 211, a feeding pipe 213 is connected to the material guide barrel 212, a carrying frame 221 is arranged on the storage device 22, a plurality of material storage barrels 222 are installed on the carrying frame 221, and the material storage barrels 222 are respectively provided with inlet and outlet ports 223; a feeding hopper 231 is arranged in the feeding device 23, a threaded pipe 232 is opened on the feed hopper 231, and a quick-connect locking ring 233 is nested on the threaded pipe 232.

[0042] The specific working principle is as follows:

[0043] The feeding assembly 2 mainly consists of a discharging device 21, a storage device 22, a feeding device 23 and a sealing device 24. The discharging device 21 is installed at the top, and is connected to the storage hopper for storing bait under the connection of the threaded pipe 232 of the feeding device 23 at the bottom, and is quickly connected and fixed by a quick-connect lock ring 233. At the same time, with the cooperation of the negative pressure suction high-pressure conveying method formed by the structure, the bait is sucked from the feeding hopper 231 and enters the storage barrel 222 in the storage device 22. With the help of the inlet and outlet 223, under the guidance of the spraying pipe 17, after the connection is achieved, the bait is sprayed out from the guide barrel 212 above the carrier frame 221 fixed outside the storage barrel 222. The sprayed bait is sprayed out along the feeding pipe 213 in the multi-tube alignment buckle 214 of the pre-connected multi-pipe plate, and is divided into multiple aquaculture frames to realize simultaneous feeding of multiple frames, thus changing the traditional aquaculture method.

[0044] As attached Figure 5 , Fig. 9 As shown: Figure 5 It is a three-dimensional structural schematic diagram of a feeding and discharging assembly in an aquaculture bait conveyor of the present invention; Fig. 9 The present invention is a schematic diagram of the three-dimensional structure of a sealing device in an aquaculture bait conveyor.

[0045] Among them, a discharging device 21 is provided in the inlet and outlet assembly 2, a storage device 22 is connected below the discharging device 21, a feeding device 23 is connected below the storage device 22, a plurality of sealing devices 24 are provided between the discharging device 21 and the storage device 22, and a plurality of sealing devices 24 are installed between the storage device 22 and the feeding device 23; a valve seat 242 is provided in the sealing device 24, and a steel ball 241 is provided on the valve seat 242.

[0046] The specific working principle is as follows:

[0047] Two sets of sealing devices 24 are installed between the feeding device 23 and the storage device 22. Similarly, two sets of sealing devices 24 are also provided between the discharging device 21 and the storage device 22. A total of four steel balls and four valve seats 242 form a pressure valve. When the first high-pressure oil cylinder and the second oil cylinder work repeatedly, when the oil cylinder sucks the material backward, the steel balls 241 of the feeding device 23 and the storage device 22 are sucked upward by the suction force to realize the entry of bait. At the same time, the steel balls 241 between the discharging device 21 and the storage device 22 are engaged on the valve seats 242 under the suction force to realize automatic closure. When the oil cylinder pushes the bait, on the contrary, the oil cylinder works back and forth in a cycle to continuously suck in and push out the bait, and integrates the bait in the pipeline into viscous bait. When it is subsequently placed in the breeding frame, due to the viscosity and density of the bait, it will float on the water surface and is not easy to disperse. It will slowly oxidize on the water surface so that the cultured organisms can eat it up, and it will not directly sink to the bottom of the sea, causing unnecessary pollution to the ocean.

Fig. 9 The present invention is a schematic diagram of the three-dimensional structure of a sealing device in an aquaculture bait conveyor.

[0049] The specific working principle is as follows:

[0050] The equipment is driven by an external diesel engine. In the inlet and outlet assembly 2 next to the base 1, the threaded tube 232 in the feeding device 23 is first connected to the bin for storing bait, and then quickly fixed with a quick-connect lock ring 233. When the equipment is in operation, the pressure gauge 11 shows the internal pressure and can also derive the amount of bait released. Under the distribution of hydraulic oil in the hydraulic oil tank 8 and the circulating oil circuit block 13, the first high-pressure oil cylinder 14 and the second oil cylinder 15 are triggered to form a negative pressure suction high-pressure conveying mode. The mechanical steering valve 6 controls the conversion of the first high-pressure oil cylinder 14 and the second oil cylinder 15. The working hydraulic oil enters the circulating cooler 3 along the three-way high-pressure ball valve 4 to control the temperature of the hydraulic oil. The one-way valve 12 prevents oil leakage and backflow. The condensed water formed in the cooler is discharged into the cooling water tank 5 for collection. Driven by the reversing high-pressure oil pipe 9, the converter 16 drives the spray pipe 17 to connect with the first high-pressure oil cylinder 14 and the second oil cylinder 15. During suction, the bait is sucked from the feed hopper. 231 enters, and the pressure causes the steel ball 241 nested on the valve seat 242 above the feed hopper to move upward, and the ball valves directly connected to the guide barrel 212 and the storage barrel 222 are sucked downward under pressure to close the discharge port. When the oil cylinder is pushed out, on the contrary, the steel balls 241 on the discharge device 21 and the storage device 22 are pushed upward, and the steel ball on the feed device 23 is clamped on the valve seat 242 and closed. When the root oil cylinder is output, the energy supply pipe 164 is energized, driving the connection on the connecting block 161 The telescopic push rod 162 is pushed by the linked swing block 163 and connected to the corresponding cylinder outlet, and the bait is output along the guide barrel 212 on the connecting plate 221 fixed on the outer frame 221 of the storage barrel 222. Under the guidance of the feed pipe 213, the bait is output from the connected multi-tube alignment buckle 214 and distributed to multiple aquaculture frames for feeding the bait. When the first high-pressure cylinder 14 and the second cylinder 15 need to be repaired or maintained, the oil drain valve 7 can be used to discharge the oil in advance.
