[0039] To further illustrate the embodiments, the present application provides accompanying drawings. These drawings are part of the disclosure of the present application, which mainly serve to illustrate the embodiments, and can be used to explain the operating principles of the embodiments in conjunction with the relevant description of the specification. Those of ordinary skill in the art should be able to understand other possible implementations and advantages of the present application in conjunction with these. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0040] In the description of the present application, the terms "upper", "lower", "left", "right", "front", "back", and the like orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0041] The present application will be further described in conjunction with the drawings and specific embodiments.

[0042] Reference is made to Figures 1 to 5As shown, the granular feed hydraulic conveying system provided by the embodiment comprises a floating platform 2, a control system, a weighing and discharging device 600, a feed injection device 1 and a water pump 320. In the specific embodiment, the granular feed hydraulic conveying system is applied to the field of mariculture, and therefore the water pump 320 is a seawater pump suitable for pumping seawater. The bottom of the floating platform 2 is provided with a sealed housing 3, which has a water storage tank 310 and a water inlet pipe 4 connected to the outside of the sealed housing 3. The water inlet pipe 4 is equipped with an on-off valve 410 and a float ball regulating valve 411. In the specific embodiment, the on-off valve 410 is an electromagnetic on-off valve, which is used to control the opening or closing of the water inlet pipe 4. The float ball of the float ball regulating valve 411 is arranged in the water storage tank 310. In this way, the float ball regulating valve 411 can control the water inflow of the water inlet pipe 4 according to the water level of the water storage tank 310. When the water level of the water storage tank 310 is low, the float ball regulating valve 411 opens a larger flow passage (referring to the flow passage of the water inlet pipe 4), and the water inflow of the water inlet pipe 4 is large. When the water level of the water storage tank 310 rises, the float ball rises, and the flow passage of the water inlet pipe 4 is adjusted to be smaller, so as to reduce the water inflow of the water inlet pipe 4. In this way, the water inflow is controllable, and the water level of the water storage tank 310 can be kept stable.

[0043] Specifically, the number of water inlet pipes 4 is multiple, and in the embodiment, there are five water inlet pipes 4. Each water inlet pipe 4 is equipped with an on-off valve 410 and a float ball regulating valve 411. The use of multiple water inlet pipes 4 for water inflow can match the water inflow of the water pump 320 from the water storage tank 310. In order to prevent large debris or fish from entering, a preliminary filtering cover or the like structure can be assembled on the outside of the water inlet pipe 4.

[0044] The feed injection device 1 and the water pump 320 are assembled into the sealed housing 3. The outlet of the weighing and discharging device 600 corresponds to the feed inlet of the feed injection device 1, so as to feed the feed into the feed injection device 1. The water pump 320 is connected to the water storage tank 310 and the feed injection device 1, so as to inject the water in the water storage tank 310 into the feed injection device 1, and discharge the feed in the feed injection device 1 together with seawater to the hydraulic conveying pipe system. The control system is connected to the on-off valve 410, the water pump 320, the weighing and discharging device 600 and the feed injection device 1 respectively, so as to control the coordinated operation of each component.

[0045] In use, the system is applied to water, specifically seawater, and floats on the water surface by virtue of the buoyancy of the floating platform 2, while the sealed shell 3 at the bottom of the floating platform 2 is located underwater, and the sealed shell 3 can well ensure that water cannot penetrate from positions other than the water inlet pipe 4; in operation, the control system controls the opening of the water inlet pipe 4 by the opening and closing valve 410, and external water sources flow into the internal water storage tank 310 through the water inlet pipe 4, and the control system also controls the weighing and discharging device 600, the feed injection device 1 and the water pump 320 to work in coordination; the weighing and discharging device 600 feeds the feed into the feed injection device 1, the water pump 320 injects water in the water storage tank 310 into the feed injection device 1, and the water flow synchronously takes away the feed fed into the feed injection device 1, so as to realize the hydraulic transmission of the feed. The water discharged or leaked from the feed injection device 1 flows back to the water storage tank 310.

[0046] The water storage tank 310 is arranged in the sealed shell 3, and the purpose is to collect the water discharged or leaked from the feed injection device 1 and reuse it, so as to prevent the water discharged or leaked from the feed injection device 1 from affecting the function of the whole system.

[0047] In actual use, the sealed shell 3 is located underwater, which greatly reduces the volume exposed to the water surface, and at the same time, reduces the gravity center of the system, enhances the resistance to the influence of tides and wind, and makes the system more stable.

[0048] The floating platform 2 is provided with an installation opening penetrating upward and downward in the middle portion, the floating platform 2 is provided with an installation shell 5 in the installation opening, the outer side of the upper portion of the installation shell 5 is fixedly provided with a support frame 510 (specifically a triangular support frame), the support frame 510 abuts against the upper surface of the floating platform 2, and the lower portion of the installation shell 5 is in sealed connection with the sealed shell 3; the weighing and discharging device 600 is assembled in the installation shell 5. In this way, the connection is firm, the stress is relatively balanced, and better sealing is achieved.

[0049] The upper end of the installation shell 5 is provided with a sealing cover plate 530 to realize sealing; the sealing cover plate 530 is provided with installation boxes and feeding openings, specifically, the sealing cover plate 530 has two installation boxes and two feeding openings, the bottom of the installation box is only provided with a cable passage opening, and is used for installing other components, such as a control box of a control system; the feeding opening is obtained by forming an opening on the sealing cover plate 530, the feeding opening is in communication with the weighing and discharging device 600, and is used for feeding the feed into the weighing and discharging device 600, and the installation boxes and the feeding openings are provided with plugging covers, which are plugged when not in use. Specifically, the installation boxes and the plugging covers are the same in shape, and from the outer surface, the sealing cover plate 530 has four convex box bodies 7; two of them are installation boxes, and the other two are plugging covers covering the feeding openings.

[0050] Specifically, the mounting shell 5 is further provided with an upwardly extending vertical rod 520, and a lightning rod 521 is arranged at the top of the vertical rod 520, which plays an effective lightning protection role. A ventilation channel is formed in the vertical rod 520 and communicates with the inside of the sealed shell 3, thereby realizing the communication between the sealed shell 3 and the outside air and maintaining the air pressure balance in the sealed shell 3. The upper part of the vertical rod 520 is in a U-shaped structure to prevent seawater from entering.

[0051] The weighing and discharging device 600 comprises a hopper 610, a weighing device and a hopper door driver 620, the hopper is connected in the mounting shell 5 through the weighing device, and the hopper door driver 620 is arranged on the outlet of the hopper 610, so that the weighing device can directly weigh the hopper 610, the hopper door driver 620 and the feed stored in the hopper 610 in real time. The outlet of the hopper 610 corresponds to the feed inlet of the feed injection device 1; the output end of the weighing device is connected to a control system, and the control system is connected to the hopper door driver 620. In use, the feed in the hopper 610 is injected into the feed injection device 1 from the outlet of the hopper 610, the weighing device weighs in real time and transmits information to the control system, and when the single weight decreases to a preset value, it indicates that the single feed injection amount meets the standard, and the control system controls the hopper door driver 620 to close the outlet of the hopper 610; realizing quantitative injection.

[0052] Specifically, the hopper 610 is suspended and only assembled on the weighing device; therefore, in order to prevent the hopper 610 from swinging laterally, a limiting structure is further arranged in the embodiment to limit the hopper 610 to only lift and float but not swing laterally, so as to ensure the stable operation of the weighing and discharging device 600; specifically, the limiting structure can be realized by a limiting frame arranged on the side of the hopper 610.

[0053] More specifically, in the embodiment, the outlet of the weighing and discharging device 600 corresponds to the feed inlet of the feed injection device 1, which means that the feed inlet of the feed injection device 1 is located directly below the outlet of the weighing and discharging device 600, and the two are not directly connected to avoid affecting the weighing of the weighing device. Of course, in other embodiments, when the output flow is stable, the output amount of the feed can also be controlled by controlling the opening degree and discharging time of the outlet of the hopper 610.

[0054] For the design inside the sealed housing 3, one of the preferred solutions in this embodiment is that the bottom layer of the sealed housing 3 has a left cavity and a right cavity, the left cavity is the water storage tank 310, the water pump 320 is assembled in the right cavity, the feed injection device 1 is assembled on the upper layer of the water storage tank 310, and the upper cover of the water storage tank 310 is provided with a water leakage hole; in this way, the water discharged and leaked from the feed injection device 1 directly flows back to the water storage tank 310 below, without affecting other devices. The water leakage hole is provided with a floating ball check valve, which allows the water above to flow freely, but the water below cannot flow back up. In the abnormal situation that the floating ball regulating valve and the on-off valve fail at the same time and the water pump 320 stops working, water can only exist in the water storage tank 310, avoiding the devices below being soaked by water.

[0055] At the same time, because the water storage tank 310 and the feed injection device 1 are both arranged on the left side, it is easy to cause the center of gravity to be unstable, therefore, the upper layer of the right cavity is provided with a counterweight device, specifically, in this embodiment, the counterweight device is a counterweight water tank 330, which realizes counterweight by injecting water in the counterweight water tank 330 to maintain stability, and can be freely adjusted according to actual conditions.

[0056] Specifically, the counterweight water tank 330 is provided with a water pipe 331, which extends through the sealed housing 3 to the upper surface of the floating platform 2, and forms a sealing fit between the water pipe 331 and the sealed housing 3.

[0057] At the same time, the pellet feed hydraulic conveying system is also provided with a power supply device, which includes a generator 341 and a storage battery 342, and the power supply device supplies power to each electrical device to maintain continuous operation. Further, the storage battery 342 is arranged in the sealed housing 3, above the counterweight water tank 330 in this embodiment, with sufficient space and away from the feed injection device 1 and the water storage tank 310, ensuring the storage environment. The generator 341 is placed on the upper surface of the floating platform 2 and fixed on the support frame 510 to realize fixation. When the feed conveying operation is performed, power is supplied by the generator 341, and part of the electricity generated by the generator 341 is stored in the storage battery 342 to charge the storage battery 342; when the feed conveying operation is not performed, the storage battery 342 supplies power to the control system and other devices to meet the minimum power demand. Of course, in other embodiments, power can also be supplied from land, ships or offshore wind power and other occasions through cables.

[0058] Specifically, for the static balance of the entire device, corresponding buoyancy blocks can be added on the side with greater gravity to keep the device in a vertical state in static state. Therefore, an additional floating block 343 is added at the bottom of the floating platform 2 corresponding to the generator 341 side to increase the buoyancy of this side and maintain stability. Of course, the position and size of the floating block can be adjusted according to actual conditions.

[0059] Further, in order to prevent the power supply device from being corroded, an isolation layer can be arranged on the outer layer of the generator 341 and the battery 342 respectively.

[0060] With reference to Figures 6 to 17 As shown in the figure, in the embodiment, the specific structure of the feed injection device 1 for realizing hydraulic transmission is as follows: the feed injection device 1 comprises a stator shell 100, a rotor assembly 200 and a rotary driver 300, the rotor assembly 200 is rotatably assembled in the stator shell 100, and the rotary driver 300 (such as a driving motor) is drivingly connected with the rotor assembly 200 to drive the rotor assembly 200 to rotate in the stator shell 100. The rotor assembly 200 is provided with three accommodating cavities 201, the three accommodating cavities 201 are uniformly distributed along the circumferential direction of the rotor assembly 200, and the stator shell 100 is provided with three groups of inlet and outlet groups, the three groups of inlet and outlet groups are uniformly distributed along the circumferential direction of the stator shell 100 and sequentially arranged along the rotation direction of the rotor assembly 200 as a feed filling group, a feed discharging group and a water discharging group; the rotor assembly 200 rotates by 120° to make the three accommodating cavities 201 correspond to the three groups of inlet and outlet groups respectively, as shown in the figure, wherein, Figures 8 to 10 As shown in the figure, the accommodating cavity 201 corresponding to the feed filling group is used to fill the feed into the accommodating cavity 201 connected therewith; Figure 8 As shown in the figure, the accommodating cavity 201 corresponding to the feed filling group is used to fill the feed into the accommodating cavity 201 connected therewith; Figure 9 As shown in the figure, the accommodating cavity 201 corresponding to the feed filling group is used to fill the feed into the accommodating cavity 201 connected therewith; Figure 10 As shown in the figure, the accommodating cavity 201 corresponding to the feed filling group is used to fill the feed into the accommodating cavity 201 connected therewith;

[0061] As the three accommodating cavities 201 are defined as a first accommodating cavity, a second accommodating cavity and a third accommodating cavity respectively, at the beginning of the operation, the first accommodating cavity corresponds to the feed filling group, and the feed filling group fills the feed into the first accommodating cavity. Then, the rotor assembly 200 rotates 120° for the first time, at this time, the first accommodating cavity corresponds to the feed discharging group, and the feed discharging group injects water into the first accommodating cavity to discharge the feed in the first accommodating cavity to the hydraulic conveying pipe system; at the same time, the second accommodating cavity corresponds to the feed filling group, and the feed filling group fills the feed into the second accommodating cavity. Then, the rotor assembly 200 rotates 120° for the second time, at this time, the first accommodating cavity corresponds to the water draining group, and the water draining group drains the water remaining in the first accommodating cavity, the second accommodating cavity corresponds to the feed discharging group, and the feed discharging group injects water into the second accommodating cavity to discharge the feed in the second accommodating cavity to the hydraulic conveying pipe system, and the third accommodating cavity corresponds to the feed filling group, and the feed filling group fills the feed into the third accommodating cavity. Then, the rotor assembly rotates 120° for the third time, at this time, the first accommodating cavity corresponds to the feed filling group again, and the feed filling group fills the feed into the first accommodating cavity, the second accommodating cavity corresponds to the water draining group, and the water draining group drains the water remaining in the second accommodating cavity, and the third accommodating cavity corresponds to the feed discharging group, and the feed discharging group injects water into the third accommodating cavity to discharge the feed in the third accommodating cavity to the hydraulic conveying pipe system. In this way, the rotor assembly 200 can synchronously perform the actions of feed filling, water injection and discharge and water draining every 120° of rotation, so as to quickly inject the feed into the hydraulic conveying pipe system, and the feed supply efficiency is high; and the feed is discharged together by the water injection mode, so as to reduce the wear of the feed, and the low-loss discharge of the feed can be realized. The device provided in the application has a simple structure design and good feed supply effect.

[0062] The scheme of the application enables the technology of feeding by using hydraulic conveying to be realized, and further realizes the feeding of a long distance, so as to realize the demand of feeding of a long distance on the sea or feeding of a long distance to the sinking type net cage. The key technical link of automatic hydraulic feeding conveying is solved.

[0063] The three accommodating cavities 201 are the same in structure, and each has an upper opening 202 and a lower opening 203; the accommodating cavity 201 is provided with a filter screen with a mesh smaller than the diameter of the granular feed, and the filter screen is used for supporting the granular feed and preventing the feed from leaking out of the lower opening 203, and meanwhile, the filter screen does not hinder the flow of water.

[0064] Specifically, the rotor assembly 200 comprises a rotor upper part 21, a rotor middle part 22 and a rotor lower part 23 connected in sequence from top to bottom, the upper opening 202 is formed in the rotor upper part 21, the chamber 204 of the containing cavity 201 is formed in the rotor middle part 22, specifically, the chamber 204 of the containing cavity 201 is a vertical through cavity of the rotor middle part 22, and the lower opening 203 is formed in the rotor lower part 23; in this way, the upper opening 202, the chamber 204 and the lower opening 203 are prepared separately, and then the rotor upper part 21, the rotor middle part 22 and the rotor lower part 23 are spliced and fixed to obtain the rotor assembly 200, which is easier to process and assemble.

[0065] The filter screen is assembled on the rotor lower part 23, specifically, the rotor lower part 23 is provided with a mounting port, and the filter screen is fixedly assembled on the mounting port; in this way, the filter screen is assembled on the rotor lower part 23 before the rotor middle part 22 and the rotor lower part 23 are assembled, which facilitates the installation of the filter screen.

[0066] Of course, in other embodiments, the structure of the rotor assembly 200 is not limited to this, for example, the rotor upper part 21, the rotor middle part 22 and the rotor lower part 23 can also be integrally connected.

[0067] Specifically, referring to Figure 8 As shown, the feed filling group comprises a feed injection port 111 arranged above the stator shell 100 and a lower outlet 112 arranged below the feed injection port 111; when the rotor assembly 200 rotates to a containing cavity 201 corresponding to the feed filling group, the feed injection port 111 is communicated with the upper opening 202 of the containing cavity 201, and the lower outlet 112 is communicated with the lower opening 203 of the containing cavity 201; the stator shell 100 is provided with an injection hopper 31 connected with the feed injection port 111; specifically, the injection hopper 31 is the feed inlet of the feed injection device 1. The feed is injected from the injection hopper 31, passes through the feed injection port 111 to the containing cavity 201 corresponding thereto, and is supported by the filter screen in the containing cavity 201.

[0068] Specifically, referring to Figure 9As shown, the feed discharge group includes a feed discharge port 113 opened above the stator shell 100 and a water inlet 114 located below the feed discharge port 113. When the rotor assembly 200 rotates to a position where one of the holding cavities 201 corresponds to the feed discharge group, the feed discharge port 113 communicates with the upper opening 202 of the holding cavity 201, and the water inlet 114 communicates with the lower opening 203 of the holding cavity 201. The stator shell 100 is equipped with a water inlet pipe 32 connected to the water inlet 114 and a discharge pipe 33 connected to the feed discharge port 113. The discharge pipe 33 is used to externally connect a hydraulic conveying pipe system. The water inlet pipe 32 is connected to a water pump 320. The water pump 320 pumps water in the water storage tank 310 into the water inlet pipe 32 and then into the holding cavity 201. The water is injected upward from the lower opening 203 of the holding cavity 201 and finally flows into the discharge pipe 33 from the upper opening 202 of the holding cavity 201, and is discharged to the hydraulic conveying pipe system. Specifically, the discharge pipe 33 penetrates the sealing shell 3 to externally connect the hydraulic conveying pipe system, and the discharge pipe 33 and the sealing shell 3 form a sealing fit.

[0069] With reference to the drawings Figure 10 As shown, the water discharge group includes an air vent 115 opened above the stator shell 100 and a water discharge port 116 located below the air vent 115. When the rotor assembly 200 rotates to a position where one of the holding cavities 201 corresponds to the water discharge group, the air vent 115 communicates with the upper opening 202 of the holding cavity 201, and the water discharge port 116 communicates with the lower opening 203 of the holding cavity 201. The water stored in the holding cavity 201 is quickly discharged in sequence through the lower opening 203 of the holding cavity 201 and the water discharge port 116, so as to be injected with feed next time. Specifically, the stator shell 100 is provided with an air vent pipe 34 connected to the air vent 115.

[0070] The stator housing 100 comprises a cylindrical housing body 11, an upper bushing 12, a lower bushing 13, an upper cover plate 14 and a lower cover plate 15; the upper bushing 12 and the lower bushing 13 are fixed at the upper end position and the lower end position of the inner cavity of the housing body 11 respectively, and the upper bushing 12 and the lower bushing 13 are in static sealing cooperation with the housing body 11. The rotor assembly 200 is assembled in the upper bushing 12 and the lower bushing 13, the upper cover plate 14 is covered on the end opening of the upper bushing 12, and the lower cover plate 15 is covered on the end opening of the lower bushing 13; the upper end of the rotor assembly 200 is in rotary cooperation with the upper cover plate 14 through a bearing (defined as an upper bearing 61), and the lower end of the rotor assembly 200 is in rotary cooperation with the lower cover plate 15 through a bearing (defined as a lower bearing 62). Specifically, the upper end of the rotor assembly 200 is an upper output disc shaft 24, the upper output disc shaft 24 is in rotary cooperation with the upper cover plate 14 through the upper bearing 61, and at the same time, the upper output disc shaft 24 has a driving shaft which extends upwardly beyond the upper cover plate 14 and is used for connecting a rotary driving device. The lower end of the rotor assembly 200 is a lower output disc shaft 26, the lower output disc shaft 26 is in rotary cooperation with the lower cover plate 15 through the lower bearing 62.

[0071] Further, in order to facilitate assembly with the upper bearing 61, a first mounting port 141 is formed in the middle part of the upper cover plate 14 in the embodiment, the outer ring of the upper bearing 61 is sleeved in the first mounting port 141 of the upper cover plate 14, and in order to protect the upper bearing 61, an upper bearing gland 16 is further covered on the top of the upper cover plate 14, the upper bearing gland 16 blocks the first mounting port 141 of the upper cover plate 14 and positions the upper bearing 61.

[0072] Similarly, in order to facilitate assembly with the lower bearing 62, a second mounting port 154 is formed in the middle part of the lower cover plate 15 in the embodiment, the outer ring of the lower bearing 62 is sleeved in the second mounting port 154 of the lower cover plate 15, and in order to protect the lower bearing 62, a lower bearing gland 17 is further covered on the bottom of the lower cover plate 15, the lower bearing gland 17 blocks the second mounting port 154 of the lower cover plate 15 and positions the lower bearing 62.

[0073] The upper bushing 12 and the lower bushing 13 are arranged to cooperate with the upper rotor part 21 and the lower rotor part 23 of the rotor assembly 200, and the middle rotor part 22 of the rotor assembly 200 is spaced apart from the housing body 11. In this way, under the condition that the sizes of the housing body 11 and the rotor assembly 200 are fixed, the optimal size cooperation between the rotor assembly 200 and the stator housing 100 can be achieved by adjusting the thickness of the upper bushing 12 and the lower bushing 13.

[0074] The feed filling group feed inlet 111, the feed discharge group feed outlet 113 and the water discharge group air vent 115 all simultaneously penetrate the upper bushing 12 and the outer shell 11; the feed filling group lower outlet 112, the feed discharge group water inlet 114 and the water discharge group water outlet 116 all simultaneously penetrate the lower bushing 13 and the outer shell 11.

[0075] In order to reduce the friction between the rotor assembly 200 and the stator shell 100 when rotating, the rotor assembly 200 has a large gap with the upper bushing 12 and the lower bushing 13, and for this reason, the rotor assembly 200 is equipped with a sealing ring (defined as a first sealing ring) on both sides of the upper opening 202 and on both sides of the lower opening 203, and the first sealing ring forms an incomplete sealing fit with the stator shell 100; that is, the first sealing ring arranged on both sides of the upper opening 202 of the rotor assembly 200 forms an incomplete sealing fit with the upper bushing 12; the first sealing ring arranged on both sides of the lower opening 203 of the rotor assembly 200 forms an incomplete sealing fit with the lower bushing 13. The first sealing ring forms an incomplete sealing fit with the stator shell 100, which on the one hand effectively reduces the leakage of water from the upper and lower gaps, and only allows a small amount of water to seep out from the first sealing ring, and on the other hand, avoids excessive wear of the first sealing ring, and the water seeping out from the first sealing ring also has a good lubricating effect on the first sealing ring, effectively improving the service life and reducing the maintenance frequency.

[0076] Further, the stator shell 100 is provided with a first water leakage opening 41 on both sides of the upper opening 202 of the accommodating cavity 201 and on both sides of the lower opening 203 of the accommodating cavity 201, which can timely discharge the leaked water and prevent the water from continuing to seep into the rotating bearing.

[0077] Specifically, the rotor middle part 22 of the rotor assembly 200 has a large space with the outer shell 11 to collect water, which is then uniformly discharged from the first water leakage opening 41. The upper side position of the rotor assembly 200 at the upper opening 202 has a small gap with the upper bushing 12, and the lower side position of the rotor assembly 200 at the lower opening 203 has a small gap with the lower bushing 13, and water is not easy to collect at these two positions, therefore, the rotor assembly 200 is provided with a water leakage ring groove 205 at the upper side position of the upper opening 202 and at the lower side position of the lower opening 203, and the first water leakage opening 41 is correspondingly arranged, and the water leakage ring groove 205 can effectively collect water, which is then uniformly discharged from the first water leakage opening 41.

[0078] At the same time, at the same level as the water inlet 114, the gap between the rotor assembly 200 and the lower bushing 13 will also seep water, in order to avoid the high-pressure water entering from the water inlet 114 from seeping into the other two groups (i.e. the feed filling group and the water discharge group) and affecting the operation, such as Figure 13As shown, in the embodiment, the stator housing 100 is provided with a second water leakage opening 42 at the same level as the lower opening 203 of the accommodating cavity 201, which is arranged between the feed discharging group and the feed filling group and between the feed discharging group and the water draining group; in this way, the water leaked from the fitting gap will first leak out from the second water leakage opening 42 before reaching the feed filling group and the water draining group.

[0079] Similarly, the high-pressure water discharged from the feed discharging port 113 of the feed discharging group will also seep out from the fitting gap at this level, therefore, as shown in Figure 12 As shown, the stator housing 100 is provided with a third water leakage opening 43 at the same level as the upper opening 202 of the accommodating cavity 201, which is arranged between the feed discharging group and the feed filling group and between the feed discharging group and the water draining group; in this way, the water leaked from the fitting gap will first leak out from the third water leakage opening 43 before reaching the feed filling group and the water draining group.

[0080] Specifically, the fitting mode of the rotor assembly 200 and the stator housing 100 enables the device to operate better, and the water seeped from the fitting gap is in a small amount, which basically does not affect the operation of the device.

[0081] Further, the water inlet pipe 32 is connected to the water pump, which is continuously operated during operation. When the lower opening 203 of the accommodating cavity 201 is staggered with the water inlet port 114, the water in the water inlet pipe 32 will be blocked, which will affect the water pump and even damage it. Therefore, in the embodiment, the rotor assembly 200 is provided with an auxiliary passage 501, and the stator housing 100 is provided with an auxiliary water inlet port 121 and an auxiliary water outlet port 122, as shown in Figure 14 and Figure 15 As shown, the number of auxiliary water inlet ports 121 is one, and the number of auxiliary water outlet ports 122 is two, forming a one-in and two-out structure; of course, the number of auxiliary water inlet ports 121 and auxiliary water outlet ports 122 is not limited to this. When the rotor assembly 200 rotates to the position where the accommodating cavity 201 is staggered with the inlet and outlet groups, as shown in Figure 15 As shown, the auxiliary water inlet port 121 and the auxiliary water outlet port 122 are connected to the auxiliary passage 501 of the rotor assembly 200, and the auxiliary water inlet port 121 shares the water inlet pipe 32 with the water inlet port 114. In this way, when the water inlet port 114 is blocked, the water in the water inlet pipe 32 can enter the auxiliary passage 501 from the auxiliary water inlet port 121 and then flow out from the auxiliary water outlet port 122, avoiding the influence of the water pump caused by the blocking of the water inlet pipe 32. When the lower opening 203 of the accommodating cavity 201 corresponds to the water inlet port 114, as shown in Figure 14 As shown, the auxiliary water inlet port 121 and the auxiliary passage 501 are staggered, and the water flows in from the water inlet port 114.

[0082] Furthermore, the rotor assembly 200 also includes an auxiliary part 25, which is spliced ​​to the lower end of the rotor lower part 23. The auxiliary channel 501 is formed on the auxiliary part 25. Specifically, the auxiliary part 25 also forms an incomplete sealing fit with the lower bushing 13 through the first sealing ring. A water leakage ring groove 205 is also provided below the auxiliary channel 501, and a first water leakage port 41 corresponding to the water leakage ring groove 205 below the auxiliary channel 501 is also provided on the stator housing 100 to realize water collection and unified discharge.

[0083] Furthermore, the auxiliary water outlet 122 is connected to the auxiliary water outlet pipe 37, and the auxiliary water outlet pipe 37 is connected to the discharge pipe 33. The water flowing out of the auxiliary water outlet 122 is also discharged into the hydraulic conveying system through the discharge pipe 33, which simplifies the structure and at the same time can further clean up any feed that may remain in the discharge pipe 33.

[0084] Meanwhile, in order to ensure that the upper bearing 61 at the upper end and the lower bearing 62 at the lower end of the rotor assembly 200 are not easily affected by water seeping out from the gap, in this embodiment, at the upper end of the rotor assembly 200, the upper output disc shaft 24 is provided with an upwardly protruding first annular wall 241 around the upper bearing 61. The first annular wall 241 cooperates with the upper cover plate 14 through a sealing ring (defined as the second sealing ring). At the same time, on the outside of the first annular wall 241, the upper bushing 12 is also provided with a fourth water outlet 44. With this configuration, the high-pressure water discharged from the feed outlet 113 of the feed discharge group seeps upward through the upper water leakage ring groove 205 and is discharged from the first water outlet 41. If the water in the water leakage ring groove 205 seeps upward to the upper output disc shaft 24, then this part of the water will also be discharged from the fourth water outlet 44. Furthermore, the first annular wall 241 provided around the upper bearing 61 and the structure in which the first annular wall 241 and the upper cover plate 14 are fitted by the second sealing ring can further ensure that the water will not cross the first annular wall 241 and come into contact with the upper bearing 61.

[0085] At the lower end of the rotor assembly 200, such as Figure 17 As shown, the lower cover plate 15 has an upwardly protruding second annular wall 151 around the lower bearing 62. The outer ring of the lower bearing 62 is fitted onto the inner annular wall of the second annular wall 151. The outer annular wall of the second annular wall 151 is engaged with the lower output disc shaft 26 through a third sealing ring. The outer periphery of the second annular wall 151 forms an annular groove 153. The lower cover plate 15 also has a water leakage hole 152 that runs vertically through the groove 153. When water seeps into the lower cover plate 15 from the gap between the lower output disc shaft 26 and the lower bushing 13, the water will collect in the groove 153 and then leak out in time from the water leakage hole 152. In this way, water is effectively prevented from contacting the lower bearing 62.

[0086] Specifically, the above control system can use the existing structure, such as the control system can use PLC control system, to realize the coordinated operation of each component control, control system and weighing device 600, feed injection device 1 and the connection and control principle of water pump 320 and so on are all prior art, has been mastered and implemented, will not be described here.

[0087] Further, the above-mentioned pellet feed hydraulic delivery system is the preferred scheme in this application, of course, in other embodiments, not limited to this, such as the layout of each component in the sealed shell 3 can be redesigned, such as the heavier water storage tank 310 and the feed injection device 1 can be set in the middle position, to keep the center of gravity in the middle, other lighter components are distributed in the periphery, so that the structure of the counterweight water tank 330 can be saved, but it may cause the storage of too many accessories and may make other components (such as batteries) too close to the water source and cause the impact; or, the feed injection device 1 can use two sets of inlet and outlet groups and two containing cavities (i.e. eliminate the structure of the water outlet group), or use four or more inlet and outlet groups and containing cavities, etc.

[0088] Example two

[0089] The pellet feed hydraulic delivery system provided in this embodiment is basically the same as the pellet feed hydraulic delivery system provided in example one, the difference is that: referring to Figure 18 As shown in the figure, in this embodiment, the counterweight device arranged in the right side of the sealed shell 3 is a generator 341; such arrangement not only saves the components of the counterweight increase (such as the counterweight water tank 330 in example one), but also can make the generator 341 get good isolation protection, prevent the generator 341 from being corroded by external water vapor. The generator 341 has an air inlet, a smoke outlet and an oil inlet. The three ports are connected with corresponding pipelines to realize the functions of air inlet, smoke exhaust and oiling.

[0090] Although the present application is specifically shown and introduced in combination with the preferred embodiments, those skilled in the art should understand that various changes can be made in form and detail without departing from the spirit and scope of the present application defined in the appended claims, and all such changes are within the protection scope of the present application.
