[0045] The present invention is further described in detail below in conjunction with the accompanying drawings and implementations. It is to be understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings.

[0046] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] like Figure 1 , Figure 2 As shown, the utility model provides a conical disc centrifugal shellfish seeding device, comprising a supporting frame 1, on which is mounted a material holding device for storing shellfish seedlings, and the material holding device is provided with a material dropping port 6, through which the shellfish seedlings stored in the material holding device are dropped; a centrifugal turntable 8 is also mounted on the supporting frame 1, and the centrifugal turntable 8 can be fully rotated within a certain speed range on the supporting frame 1, and the material dropping port 6 on the material holding device is located above the centrifugal turntable 8, so that the shellfish seedlings delivered through the material dropping port 6 directly enter the centrifugal turntable 8; a plurality of material dispensing blades are also mounted on the centrifugal turntable 8, the inner end of the material dispensing blade is close to the center of the centrifugal turntable 8, the outer end of the material dispensing blade extends to the outside of the centrifugal turntable 8, and the surface of the material dispensing blade is perpendicular to the upper surface of the centrifugal turntable 8, and the plurality of material dispensing blades are arranged at intervals along the circumferential direction of the centrifugal turntable 8.

[0048] When the shellfish seedlings stored in the material holding device fall onto the centrifugal turntable 8 through the material dropping port 6, the centrifugal turntable 8 rotates so that the shellfish seedlings falling onto the centrifugal turntable 8 are thrown out under the guidance of the material dispensing blades, thereby achieving the sowing of the shellfish seedlings.

[0049] like Figure 6As shown, the upper surface of the centrifugal turntable 8 is not a flat surface, but an inverted cone shape, which gradually tilts upward from the center of the centrifugal turntable 8 to the edge of the centrifugal turntable 8, so that during the rotation of the centrifugal turntable 8, the shellfish seedlings on the centrifugal turntable 8 are thrown outward by the centrifugal force, and the shellfish seedlings will gradually move upward through the guidance of the upper surface of the centrifugal turntable 8, so that during the throwing process, the shellfish seedlings will first move upward while moving outward, and when the shellfish seedlings reach the highest point, the shellfish seedlings will move downward while moving outward, so that the throwing trajectory of the shellfish seedlings is a lower opening parabola, thereby increasing the sowing width and avoiding the influence of the sowing width on the height of the equipment of the centrifugal shellfish seeding device loaded with a cone disk from the beach or the sea surface. In the utility model, taking a flat disk (a disk with a flat upper surface) and a conical disk (a centrifugal turntable 8 in an inverted cone shape) with the same diameter as an example, the sowing width of the flat disk is about 10m, and the sowing width of the conical disk can be about 20m.

[0050] The taper of the centrifugal turntable 8 is 6.5° to 8.5°. When the taper of the centrifugal turntable 8 is 7.72°, the centrifugal turntable 8 has a better effect on scattering the shellfish seedlings. At this time, the width of the centrifugal turntable 8 for scattering the shellfish seedlings reaches the maximum; of course, without considering the width of scattering the shellfish seedlings, the centrifugal turntable 8 can directly adopt a circular disc with a flat upper surface or a centrifugal turntable 8 with an arbitrary taper.

[0051] like Figure 1 , Figure 6 , Figure 7 , Figure 8 As shown, the material-dispensing blade includes a long blade 9 and a short blade 10, and the short blade 10 is installed at the outer end of the long blade 9. In order to avoid the installation of the short blade 10 being restricted by the centrifugal turntable 8, the outer end of the long blade 9 can be extended to the outside of the centrifugal turntable 8 before the short blade 10 is installed, so that the short blade 10 has no matching relationship with the centrifugal turntable 8 during installation. The long blade 9 and the short blade 10 cooperate with each other, which can effectively increase the length of the material-dispensing blade, so that when the centrifugal turntable 8 rotates, the distance that the shellfish seedlings are guided by the material-dispensing blade is larger during the process of throwing outward, thereby further increasing the sowing width.

[0052] After the short blade 10 is installed on the long blade 9, the short blade 10 can be adjusted to be tilted upward or tilted downward on the long blade 9, that is, the central axis of the short blade 10 can be gradually tilted upward or gradually tilted downward relative to the central axis of the long blade 9. By adjusting the inclination angle of the short blade 10 relative to the long blade 9, the sowing width can be further increased, so that the original sowing width of about 20m can reach about 28m.

[0053] In order to make the adjustment of the short blade 10 more convenient, an arc hole and a screw hole can be provided at the outer end of the long blade 9, the center of the arc hole coincides with the screw hole, and through holes corresponding to the arc hole and the screw hole are provided on the short blade 10, and bolts for locking the long blade 9 and the short blade 10 are installed in the through hole and the screw hole, and in the arc hole and the through hole. When the inclination of the short blade 10 needs to be adjusted, the bolts in the through hole and the screw hole, and in the arc hole and the through hole are loosened, and the short blade 10 is swung. After the inclination angle of the short blade 10 is fixed, the bolts in the through hole and the screw hole, and in the arc hole and the through hole can be locked, which is convenient for adjustment.

[0054] The material-discharging blade can adjust its offset angle to both sides relative to the radius of the centrifugal turntable 8. Taking the inner end of the material-discharging blade as a reference, the outer end of the material-discharging blade can be tilted and adjusted to both sides of the radius of the centrifugal turntable 8, so that the central axis of the material-discharging blade deviates from the radius of the centrifugal turntable 8, and the specific offset angle of the material-discharging blade is -0.9°. By adjusting the offset angle of the material-discharging blade relative to the radius of the centrifugal turntable 8, not only can the sowing width be further increased, but also the falling area of ​​the shellfish seedlings and the sowing uniformity of the shellfish seedlings can be adjusted.

[0055] In the present invention, the adjustment of the material-dispensing blade to both sides relative to the radius of the centrifugal turntable 8 can also be based on the outer end of the material-dispensing blade, so that the inner end of the material-dispensing blade can be tilted and adjusted to both sides of the radius of the centrifugal turntable 8.

[0056] like Figure 7 , Figure 8 As shown, the long blade 9 and the short blade 10 both include a web 91, an upper flange 92, and a lower flange 93, and the upper flange 92 and the lower flange 93 are respectively located on both sides of the web 91, and the web 91, the upper flange 92, and the lower flange 93 are an integrated structure, so that the cross-section of the long blade 9 and the short blade 10 is U-shaped. When it is necessary to install the material-dispensing blade, the lower flange 93 on the long blade 9 can be directly fixed on the centrifugal turntable 8, so that the installation of the material-dispensing blade is more convenient; at the same time, by providing the long blade 9 and the short blade 10 with an upper flange 92, when the centrifugal turntable 8 is rotating, the upper flange 92 on the long blade 9 and the short blade 10 can play the role of catching the material when the shellfish seedlings are jointly guided and scattered outward by the long blade 9 and the short blade 10, thereby preventing the shellfish seedlings from flying directly upward from the upper edges of the long blade 9 and the short blade 10, thereby ensuring the sowing effect of the shellfish seedlings.

[0057] In order to facilitate the adjustment of the offset angle of the material-dispensing blade relative to the centrifugal turntable 8, a screw hole can be opened at the outer edge of the centrifugal turntable 8, and an arc hole can be opened near the center of the centrifugal turntable 8, and the center of the arc hole can be made to coincide with the screw hole; at the same time, a through hole corresponding to the screw hole is opened at the outer end of the lower flange 93 of the long blade 9, and a through hole corresponding to the arc hole is opened at the inner end of the lower flange 93 of the long blade 9, and bolts for locking the long blade 9 and the centrifugal turntable 8 are installed in the through hole and the screw hole, and in the arc hole and the through hole. When it is necessary to adjust the inclination of the material-dispensing blade, loosen the bolts in the through hole and the screw hole, and in the arc hole and the through hole, swing the long blade 9, and after the inclination angle of the long blade 9 is fixed, lock the bolts in the through hole and the screw hole, and in the arc hole and the through hole, which is convenient for adjustment.

[0058] The width of the outer end of the web 91 of the long blade 9 gradually decreases along the discharge direction, and the upper flange 92 and the lower flange 93 are not required to be set on the width-reducing section of the web 91 of the long blade 9, and when the long blade 9 and the short blade 10 are installed in cooperation, the width-reducing section of the web 91 of the long blade 9 is inserted between the upper flange 92 of the short blade 10 and the lower flange 93 of the short blade 10. When the short blade 10 and the long blade 9 are fixed, the upper flange 92 on the short blade 10 is butted against the upper flange 92 on the long blade 9, and the lower flange 93 on the short blade 10 is butted against the lower flange 93 on the long blade 9, thereby forming a complete material-discharging blade. By gradually reducing the width of the outer end of the web 91 of the long blade 9 along the discharge direction, when the short blade 10 needs to be adjusted on the long blade 9 to tilt upward or downward, the upper and lower sides of the long blade 9 will not restrict the swing of the short blade 10, thereby ensuring the adjustment of the short blade 10, so that the short blade 10 can tilt upward or downward relative to the long blade 9 to a greater extent.

[0059] The inner end of the upper flange 92 of the long blade 9 and the outer end of the upper flange 92 of the short blade 10 are both provided with chamfers 12, so that when the centrifugal turntable 8 is rotating, the shellfish seedlings are guided by the material-dispensing blades to be spread outward, which not only facilitates the shellfish seedlings to enter between the upper flange 92 on the long blade 9 and the lower flange 93 of the long blade 9, but also facilitates the shellfish seedlings to be spread out through the chamfers 12 on the upper flange 92 of the short blade 10 after being guided by the short blade 10, effectively avoiding the shellfish seedlings from being damaged by colliding with the right angle of the upper flange 92 of the long blade 9, or being damaged by colliding with the right angle of the upper flange 92 of the short blade 10, thereby effectively reducing the damage rate of the shellfish seedlings.

[0060] The support frame 1 is also equipped with an AC motor 13 for driving the centrifugal turntable 8. The AC motor 13 is equipped with a speed regulator, which can effectively control the speed of the AC motor 13. The centrifugal turntable 8 is driven by the AC motor 13 to rotate at a high speed, so that the shellfish seedlings on the centrifugal turntable 8 are subjected to a centrifugal force, so that the shellfish seedlings on the centrifugal turntable 8 are thrown out to achieve the sowing of the shellfish seedlings. In the utility model, when it is necessary to adjust the sowing width of the shellfish seedlings, the speed of the AC motor 13 can also be adjusted by the speed regulator to adjust the speed of the centrifugal turntable 8, so that the centrifugal force on the shellfish seedlings on the centrifugal turntable 8 changes, and the sowing distance of the shellfish seedlings changes. In the utility model, under the condition of meeting the driving requirements of the centrifugal turntable 8, the AC motor 13 can also be replaced by a DC motor.

[0061] In order to avoid the shellfish seedlings falling from the drop port 6 being damaged when the centrifugal turntable 8 is installed at the output end of the AC motor 13 because the output end of the AC motor 13 passes through the part of the centrifugal turntable 8, or because the screws used to fix the centrifugal turntable 8 to the output end of the AC motor 13 directly expose the upper surface of the centrifugal turntable 8, a protective cover 11 is also installed in the center of the centrifugal turntable 8, and the output end of the AC motor 13 or the screws fixing the centrifugal turntable 8 are covered in the protective cover, and the drop port 6 and the protective cover 11 are staggered. This can not only prevent the shellfish seedlings from falling into the gap between the output end of the AC motor 13 and the inner end of the material-dispensing blade to form a blockage, prevent the rotation of the AC motor 13 from causing the rotation of the rotating shaft, but also effectively prevent the shellfish seedlings from accumulating in the center of the centrifugal turntable 8.

[0062] When there are four material-discharging blades on the centrifugal turntable 8, the four material-discharging blades divide the centrifugal turntable 8 into four quadrants. The utility model is directly loaded at the rear of a ship or a vehicle when in use. At this time, the quadrants are divided with the forward direction of the ship or the vehicle as the positive direction of the Y-axis, and the material-dropping port 6 corresponds to the second quadrant of the centrifugal turntable 8, which can effectively ensure that the sowing direction of the shellfish seedlings is the negative direction of the Y-axis, that is, sowing toward the stern.

[0063] like Figure 1 , Figure 2 , Figure 3 As shown, the material holding device includes a hopper body 2, which is fixed on the upper part of the supporting frame 1. A discharge port 4 is opened at the bottom of the hopper body 2, and the shellfish seedlings in the hopper body 2 are sent out of the hopper body 2 through the discharge port 4; at the same time, a guiding slope 5 is connected between the discharge port 4 and the drop port 6, and the high end of the guiding slope 5 is connected to the discharge port 4, and the low end of the guiding slope 5 is connected to the drop port 6, so that the shellfish seedlings sent out through the discharge port 4 are guided by the guiding slope 5 and then enter the drop port 6. The guiding slope 5 can buffer the shellfish seedlings before they fall from the drop port 6 onto the centrifugal turntable 8, thereby effectively preventing the shellfish seedlings from being damaged.

[0064] In order to prevent the shellfish seedlings that fall on the guide slope 5 from falling directly out from the two sides of the guide slope 5 when moving downward to the discharge port 6, a baffle can also be set on both sides of the guide slope 5 to make the guide slope 5 into a ditch shape. Without affecting the downward inclined movement of the shellfish seedlings after being discharged from the discharge port 4, the shellfish seedlings will not be scattered at will, thereby reducing the waste or damage to the shellfish seedlings.

[0065] The inclination angle of the guiding slope 5 is greater than the repose angle of the shellfish seedlings. Specifically, the inclination angle of the guiding slope 5 is greater than 42°, which can provide buffering and direction guidance for the shellfish seedlings and reduce the impact force of the falling shellfish seedlings.

[0066] The bottom of the hopper body 2 is closed by a guide slope 5, and the discharge port 4 is located on the side of the hopper, and the lower end of the discharge port 4 is directly flush with the bottom of the hopper body 2, that is, the discharge port 4 is ∩-shaped. At this time, the shellfish seedlings in the hopper body 2 are located at the high end of the guide slope 5 when entering the bottom of the hopper body 2, and through the guidance of the guide slope 5 and the gravity of the shellfish seedlings themselves, the shellfish seedlings move downward along the guide slope 5 and pass through the discharge port 4 into the drop port 6, so that the shellfish seedlings in the hopper body 2 can gradually enter the drop port 6 in turn, which not only effectively reduces the drop height, but also effectively reduces the degree of damage to the shellfish seedlings.

[0067] like Figure 1 , Figure 2 , Figure 3 As shown, a baffle plate 3 for controlling the opening of the discharge port 4 is also installed on the hopper body 2. The opening of the discharge port 4 is controlled by the baffle plate 3, thereby controlling the amount of shellfish seedlings discharged through the discharge port 4, which not only avoids the sowing of shellfish seedlings being affected by excessive accumulation of shellfish seedlings on the centrifugal turntable 8, but also avoids excessive sowing density of shellfish seedlings caused by excessive accumulation of shellfish seedlings on the centrifugal turntable 8.

[0068] The baffle plate 3 is hingedly mounted on the hopper body 2. By rotating the baffle plate 3, the spacing between the lower end of the baffle plate 3 and the upper surface of the guide slope 5 changes, thereby changing the amount of shellfish seedlings passing through the spacing, thereby adjusting the opening of the discharge port 4. In order to ensure that the baffle plate 3 will not be reset due to its own gravity after rotating to a certain angle, an electric push rod can be directly used to drive the baffle plate 3 to flip. Specifically, the electric push rod is hingedly mounted in front of the baffle plate 3 or behind the baffle plate 3, and the output end of the electric push rod is directly hinged to the baffle plate 3 or hinged through a connecting rod. The baffle plate 3 is flipped by the contraction of the electric push rod. When the baffle plate 3 flips to a certain angle, the electric push rod stops driving. At this time, the baffle plate 3 remains fixed, so that the opening of the discharge port 4 is maintained after adjustment.

[0069] Of course, in the present invention, in order to maintain the opening of the discharge port 4 after adjustment, other structures can also be used. For example, a hook 14 is hinged on the baffle plate 3, and a plurality of hanging rings of different heights are provided on the hopper body 2. When the baffle plate 3 is rotated to a certain angle, the hook 14 can be hung on the hanging ring of the corresponding height. This structure can also prevent the baffle plate 3 from automatically resetting after being rotated to a certain angle.

[0070] The hopper body 2 is funnel-shaped, that is, the hopper body 2 is a structure with a large upper part and a small lower part. In order to increase the capacity of the hopper body 2, a heightened section can be added to the upper end of the hopper body 2, and the heightened section can be directly in the shape of a straight cylinder, so that the upper part of the hopper body 2 is a rectangular parallelepiped; the hopper body 2 includes a large inclined surface 21, a small inclined surface 22 and two asymmetric inclined surfaces 23, the large inclined surface 21 and the small inclined surface 22 are arranged relatively, and the two asymmetric inclined surfaces 23 are installed between the large inclined surface 21 and the small inclined surface 22. Through the cooperation of the large inclined surface 21, the small inclined surface 22 and the two asymmetric inclined surfaces 23, the hopper body 2 forms an inverted quadrangular pyramid structure with an asymmetric structure. After the mussels are stored in the hopper body 2, the mussels gradually move downward along the large slope 21 and the small slope 22 by their own gravity, so that the mussels can fall from the specified direction under the guidance of the large slope 21 and the small slope 22 during the downward movement, which can not only prevent the mussels from being blocked in the hopper body 2, but also prevent the mussels from being arched in the hopper body 2, and effectively prevent the mussels from being damaged during the falling process. At the same time, the discharge port 4 and the large slope 21 are located on the same side of the hopper body 2, and the inclination angles of the large slope 21 and the small slope 22 are greater than the repose angle of the mussels.

[0071] like Figure 1 As shown, a cover plate 15 is also installed on the support frame 1, and the cover plate 15 is arranged horizontally. The height of the cover plate 15 can refer to the height of the utility model installed on a ship or a vehicle. After the utility model is installed on a ship or a vehicle, the cover plate 15 needs to be higher than the edge of the ship. The centrifugal turntable 8 is installed on the cover plate 15, and the centrifugal turntable 8 can fully rotate on the cover plate 15. The cover plate 15 is also covered with a protective cover 7, and the discharge port 6 penetrates through the top of the protective cover 7 and extends downward to the top of the centrifugal turntable 8; one side of the protective cover 7 is open, and the open side of the protective cover 7 is the front of the protective cover 7, and the longitudinal axis extends from the center of the centrifugal turntable 8 to the front and rear sides of the protective cover 7. At this time, the travel direction of the ship and the sowing direction of the shellfish seedlings are consistent with the longitudinal axis direction, and the sowing direction of the shellfish seedlings is opposite to the travel direction of the ship. In addition, the transverse axis extends from the center of the centrifugal turntable 8 to the left and right sides of the protective cover 7. The second quadrant referred to in the correspondence between the discharge port 6 and the second quadrant of the centrifugal turntable 8 is the second quadrant divided by the longitudinal axis and the transverse axis. Fig.10 shown.

[0072] When the utility model is installed on a ship or a vehicle, the open side of the protective cover 7 faces the outside of the ship or the vehicle, and when the centrifugal turntable 8 is rotating, the mussels scattered from the centrifugal turntable 8 are directly scattered through the opening of the protective cover 7, so that the mussels are scattered from a fixed direction. Since the drop opening 6 is located in the second quadrant of the centrifugal turntable 8, when the mussels drop onto the centrifugal turntable 8 through the drop opening 6, the mussels dropped onto the centrifugal turntable 8 can be scattered immediately within the opening range of the protective cover 7 in coordination with the rotation of the centrifugal turntable 8, so that the mussels will not hit the inner wall of the protective cover 7 after being scattered through the centrifugal turntable 8, that is, the mussels will not be damaged.

[0073] like Figure 5 As shown, the two sides of the protective cover 7 are asymmetrical structures. It should be noted here that the two sides of the protective cover 7 are the left and right sides based on the opening direction of the protective cover 7; the left and right sides of the protective cover 7 are both inclined surfaces, and the inclination angles of the left and right sides of the protective cover 7 are inconsistent, so that the opening width of the protective cover 7 is larger than the rear end width of the protective cover 7, that is, the opening of the protective cover 7 is trumpet-shaped, which not only ensures that the shellfish seedlings are sown forward, but also keeps the sowing width of the shellfish seedlings fixed.

[0074] The inclination angles on both sides of the protective cover 7 are 125° and 110° respectively, so that during the rotation of the centrifugal turntable 8, the shellfish seedlings spread by the centrifugal turntable 8 can be as unobstructed as possible in the limited space, and the shellfish seedlings can be prevented from hitting the rear of the protective cover 7 as much as possible, so that the spreading angle of the shellfish seedlings starting from the drop port 6 is about 120°.

[0075] The support frame 1 is also provided with a hook 14. Since the utility model is installed on a ship or a vehicle when in use, rather than being hung on the outside of the edge of the ship or the outside of the vehicle, after the utility model is installed, the hook 14 faces outward, that is, the direction of the hook 14 on the support frame 1 is consistent with the opening direction of the protective cover 7. After the utility model is installed on the edge of the ship or the edge of the vehicle, the support frame 1 can be hung on the edge of the ship or on the vehicle through the hook 14, making the installation of the utility model more stable.

[0076] In the present invention, in order to make the appearance more concise, a cover can be provided on three or four sides of the support frame 1. When the cover only seals three sides of the support frame 1, the three sides of the support frame 1 are the three sides corresponding to the left and right rear sides of the protective cover 7; when the cover only seals four sides of the support frame 1, in order to ensure that the mussels can be spread out normally from the opening on the protective cover 7, a hole corresponding to the opening on the protective cover 7 should be provided on the cover that encapsulates the support frame 1 to avoid affecting the spreading of the mussels.

[0077] In order to facilitate the delivery of the shellfish seedlings into the hopper body 2, the utility model can also be equipped with an elevator for lifting the shellfish seedlings. The elevator can be a bucket elevator, creepers, conveyor belts, etc., so that the shellfish seedlings can be automatically delivered into the hopper body 2, which can greatly reduce manual labor.

[0078] In order to reduce the damage to the mussels as much as possible, the parts in contact with the mussels in the utility model can be directly made of EVA material or coated with a layer of EVA shock-absorbing material layer on the outside of the parts, such as: the inner wall of the hopper body 2, the guide slope 5, the material baffle plate 3, the centrifugal turntable 8, the material blade, the protective cover 11, the protective cover 7, etc. By using EVA material to treat the parts in contact with the mussels, the breakage rate of the mussels can be reduced as much as possible. The damage rate of the mussels is tested in combination with different materials and different heights. The results are shown in Table 1:

[0079] Table 1 shows the damage rate of mussel seedlings under different materials and different heights

[0080]

[0081] Through the test, it was found that the damage rate of the fry on the parts made of EVA material or on the parts wrapped with EVA shock absorbing material layer was 0 within the drop height of 1000mm. After the test measurement, the repose angle of the fry on the EVA shock absorbing material layer was 15°.

[0082] At the same time, after calculation, the relationship between the quality of the shellfish seedlings and the opening of the drop opening is:

[0083] y=89.91x 2 +18.91x-9.70

[0084] Among them, y is the mass of material dropped in one hour, in tons, and x is the opening of the drop port (0 is the minimum opening, indicating a closed state, and 1 is the maximum opening of 100%. Since blockage will occur at an opening of 0-0.25, the opening range of the drop port of this device is 0.25-1.).

[0085] When it is necessary to use the utility model to sow shellfish, the utility model is installed at the rear end of a shallow-sea vessel or a rear end of a tidal flat vehicle, and is hung on the edge of the vessel or on the vehicle through a hook 14. The shellfish are lifted and sent into the hopper body 2 by the hoist, and the baffle plate 3 is rotated to open the discharge port 4 on the hopper body 2. The shellfish in the hopper body 2 enter the guide slope 5 through the discharge port 4, and move downward along the guide slope 5, and finally fall onto the centrifugal turntable 8 through the drop port 6. At the same time, in the process of the hoist lifting the shellfish, the AC motor 13 is started, and the AC motor 13 drives the centrifugal turntable 8 to rotate. When the shellfish fall on the centrifugal turntable 8, the shellfish are quickly spread out through the opening on the protective cover 7 by the rotation of the centrifugal turntable 8, thereby achieving seeding. In the utility model, when sowing shellfish, the walking path of the shallow-sea vessel or the tidal flat vehicle is as follows: Fig. 9 shown.

[0086] The utility model can be applicable to the sowing of various shellfish; at the same time, the utility model can also be equipped with electrical components such as a controller, a power meter, a display screen, etc. At this time, the input end of the power meter is connected to the output end of the AC motor, the power meter can display the power of the AC motor, the controller and the display screen are bidirectionally connected, the input end of the electric push rod and the input end of the AC motor are connected to the output end of the controller, the display screen can not only display the rotation speed of the AC motor, the opening of the discharge port, the state of the electric push rod, the power of the AC motor and other parameters, but the staff can also input the rotation speed of the AC motor, the opening of the discharge port and other parameters to the controller through the display screen.
