[0047] The application will be described in further detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related content, and are not a limitation on the application. In addition, it should be noted that only the parts related to the application are shown in the drawings for ease of description.

[0048] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other without conflict. The application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0049] As shown in Figure 1 , Figure 2 The application provides a conical disc type precise variable clam seedling device, which comprises a support frame 1, a material containing device for storing clam seedlings is installed on the support frame 1, a blanking port 6 is arranged on the material containing device, and the clam seedlings stored in the material containing device are discharged through the blanking port 6; a centrifugal disc 8 is also installed on the support frame 1, the centrifugal disc 8 can rotate fully within a certain speed range on the support frame 1, the blanking port 6 on the material containing device is located above the centrifugal disc 8, so that the clam seedlings sent out through the blanking port 6 directly enter the centrifugal disc 8; a plurality of material stirring blades are also installed on the centrifugal disc 8, the inner end of the material stirring blade is close to the center of the centrifugal disc 8, the outer end of the material stirring blade extends to the outside of the centrifugal disc 8, the surface of the material stirring blade is perpendicular to the upper surface of the centrifugal disc 8, and the plurality of material stirring blades are arranged at intervals along the circumferential direction of the centrifugal disc 8.

[0050] When the spat larvae stored in the container device drop through the dropping port 6 onto the centrifugal disc 8, the centrifugal disc 8 is rotated to throw the spat larvae dropped on the centrifugal disc 8 out through the guidance of the stirring vane, so as to realize the seeding of the spat larvae.

[0051] As shown in Figure 6 , the upper surface of the centrifugal disc 8 is not a flat surface, but an inverted conical shape, which is gradually inclined upward from the center of the centrifugal disc 8 to the edge of the centrifugal disc 8. During the rotation of the centrifugal disc 8, the spat larvae on the centrifugal disc 8 are thrown outwards by the centrifugal force, and the spat larvae gradually move upwards through the guidance of the upper surface of the centrifugal disc 8. During the throwing process, the spat larvae first move upwards while moving outwards, and when the spat larvae reach the highest point, the spat larvae move downwards while moving outwards, so that the throwing trajectory of the spat larvae is a downward-opening parabola, thereby increasing the spreading width and avoiding the influence of the height of the device from the beach or the sea surface on the seeding width. In the present application, taking a flat disc (a disc with a flat upper surface) and a conical disc (an inverted conical centrifugal disc 8) with the same diameter as examples, the spreading width of the flat disc is about 10 m, and the spreading width of the conical disc is about 20 m.

[0052] The taper of the centrifugal disc 8 is 6.5°-8.5°, and when the taper of the centrifugal disc 8 is 7.72°, the throwing effect of the centrifugal disc 8 on the spat larvae is better, and at this time, the width of the throwing of the centrifugal disc 8 on the spat larvae reaches the maximum. Of course, without considering the width of the throwing of the spat larvae, the centrifugal disc 8 can directly adopt a disc with a flat upper surface or a centrifugal disc 8 with an arbitrary taper.

[0053] As shown in Figure 1 , Figure 6 , Figure 7 , Figure 8 , the stirring vane includes a long vane 9 and a short vane 10, and the short vane 10 is installed at the outer end of the long vane 9. In order to avoid the installation of the short vane 10 being limited by the centrifugal disc 8, the outer end of the long vane 9 can be extended to the outside of the centrifugal disc 8 before the short vane 10 is installed, so that the short vane 10 has no cooperative relationship with the centrifugal disc 8 during installation. Through the cooperation of the long vane 9 and the short vane 10, the length of the stirring vane can be effectively increased, so that the distance of the guidance of the stirring vane to the spat larvae during the throwing process of the spat larvae outwards in the rotation process of the centrifugal disc 8 is greater, thereby further increasing the spreading width.

[0054] After the short blade 10 is installed on the long blade 9, the short blade 10 can be adjusted to tilt upward or downward on the long blade 9, that is, the central axis of the short blade 10 can be gradually tilted upward or downward relative to the central axis of the long blade 9, and by adjusting the tilt angle of the short blade 10 relative to the long blade 9, the spreading width can be further increased, and the original spreading width of about 20 m can reach about 28 m.

[0055] In order to make the adjustment of the short blade 10 more convenient, an arc-shaped hole and a screw hole can be formed at the outer end of the long blade 9, the center of the arc-shaped hole coincides with the screw hole, and a through hole corresponding to the arc-shaped hole and the screw hole is formed on the short blade 10, and the through hole and the screw hole and the arc-shaped hole and the through hole are all installed with bolts that jointly lock the long blade 9 and the short blade 10. When it is necessary to adjust the tilt of the short blade 10, loosen the bolts in the through hole and the screw hole and the arc-shaped hole and the through hole, swing the short blade 10, and after the tilt angle of the short blade 10 is fixed, tighten the bolts in the through hole and the screw hole and the arc-shaped hole and the through hole, which is convenient to adjust.

[0056] The material stirring blade can be adjusted to have a biasing angle relative to the radius of the centrifugal disc 8 on both sides, and the outer end of the material stirring blade can be adjusted to tilt on both sides of the radius of the centrifugal disc 8, so that the central axis of the material stirring blade deviates from the radius of the centrifugal disc 8, and the specific biasing angle of the material stirring blade is-0.9°. By adjusting the biasing angle of the material stirring blade relative to the radius of the centrifugal disc 8, the spreading width can be further increased, and the seedling falling area and the seedling spreading uniformity can be adjusted.

[0057] In the present application, the adjustment of the material stirring blade relative to the radius of the centrifugal disc 8 on both sides can also be based on the outer end of the material stirring blade, so that the inner end of the material stirring blade can be adjusted to tilt on both sides of the radius of the centrifugal disc 8.

[0058] As shown in Figure 7 , Figure 8 The long blade 9 and the short blade 10 both include a web plate 91, an upper flange 92 and a lower flange 93, the upper flange 92 and the lower flange 93 are respectively located on both sides of the web plate 91, and the web plate 91, the upper flange 92 and the lower flange 93 are an integral structure, so that the cross section of the long blade 9 and the short blade 10 is U-shaped, and when it is necessary to install the material stirring blade, the lower flange 93 on the long blade 9 can be directly fixed on the centrifugal disc 8, so that the installation of the material stirring blade is more convenient. At the same time, by providing the upper flange 92 on the long blade 9 and the short blade 10, the upper flange 92 on the long blade 9 and the short blade 10 can play a role in containing the material during the process of guiding the seedlings to be thrown outward during the rotation of the centrifugal disc 8, so that the seedlings are prevented from flying directly upward from the upper edge of the long blade 9 and the short blade 10, and the seedling spreading effect is ensured.

[0059] In order to conveniently adjust the bias angle of the stirring vane relative to the centrifugal disc 8, a screw hole is formed at the outer edge of the centrifugal disc 8, an arc-shaped hole is formed at the position close to the center of the centrifugal disc 8, and the center of the arc-shaped hole is coincided with the screw hole; meanwhile, a through hole corresponding to the screw hole is formed at the outer end of the lower wing 93 of the long vane 9, and a through hole corresponding to the arc-shaped hole is formed at the inner end of the lower wing 93 of the long vane 9, and the bolts in the through holes and the screw hole and the through holes and the arc-shaped hole are locked to lock the long vane 9 and the centrifugal disc 8. When the inclination of the stirring vane needs to be adjusted, the bolts in the through holes and the screw hole and the through holes and the arc-shaped hole are loosened, the long vane 9 is swung, and after the inclination angle of the long vane 9 is fixed, the bolts in the through holes and the screw hole and the through holes and the arc-shaped hole are locked, which is convenient to adjust.

[0060] The outer end width of the web 91 of the long vane 9 gradually decreases along the discharging direction, and the upper wing 92 and the lower wing 93 can not be arranged on the web 91 of the long vane 9 at the width-reducing section of the web 91, and when the long vane 9 and the short vane 10 are cooperatively installed, the width-reducing section of the web 91 of the long vane 9 is inserted between the upper wing 92 of the short vane 10 and the lower wing 93 of the short vane 10, and when the short vane 10 and the long vane 9 are fixed, the upper wing 92 of the short vane 10 is butted against the upper wing 92 of the long vane 9, and the lower wing 93 of the short vane 10 is butted against the lower wing 93 of the long vane 9, thereby forming a complete stirring vane. By gradually decreasing the outer end width of the web 91 of the long vane 9 along the discharging direction, when the short vane 10 needs to be adjusted to be inclined upward or downward on the long vane 9, the upper and lower sides of the long vane 9 will not limit the swinging of the short vane 10, thereby ensuring the adjustment of the short vane 10, and the inclination range of the short vane 10 relative to the long vane 9 can be larger.

[0061] The inner end of the upper wing 92 of the long vane 9 and the outer end of the upper wing 92 of the short vane 10 are both provided with chamfers 12, so that when the centrifugal disc 8 rotates, the spatula larvae not only conveniently enter between the upper wing 92 of the long vane 9 and the lower wing 93 of the long vane 9 in the process of being guided outward and scattered by the stirring vane, but also conveniently scatter out through the chamfer 12 on the upper wing 92 of the short vane 10 after being guided by the short vane 10, thereby effectively avoiding the damage of the spatula larvae due to the impact on the right angle of the upper wing 92 of the long vane 9 or the impact on the right angle of the upper wing 92 of the short vane 10, and effectively reducing the damage rate of the spatula larvae.

[0062] The support frame 1 is also provided with an alternating current motor 13 for driving the centrifugal rotating disc 8, the alternating current motor 13 is provided with a speed regulator, the speed regulator can effectively control the rotating speed of the alternating current motor 13, the centrifugal rotating disc 8 is driven by the alternating current motor 13 to rotate at a high speed, so that the spat larvae on the centrifugal rotating disc 8 are subjected to a centrifugal force, the spat larvae on the centrifugal rotating disc 8 are scattered to realize the sowing of the spat larvae. In the application, when it is necessary to adjust the sowing width of the spat larvae, the rotating speed of the alternating current motor 13 can be adjusted by the speed regulator, so as to adjust the rotating speed of the centrifugal rotating disc 8, the centrifugal force acting on the spat larvae on the centrifugal rotating disc 8 is changed, and the sowing distance of the spat larvae is changed. In the application, under the condition of meeting the driving requirement of the centrifugal rotating disc 8, the alternating current motor 13 can also be replaced by a direct current motor.

[0063] In order to avoid that, when the centrifugal rotating disc 8 is installed at the output end of the alternating current motor 13, the part of the output end of the alternating current motor 13 penetrating the centrifugal rotating disc 8 or the screw for fixing the centrifugal rotating disc 8 and the output end of the alternating current motor 13 directly exposes the upper surface of the centrifugal rotating disc 8, so that the spat larvae falling from the material falling port 6 causes damage, therefore, the centrifugal rotating disc 8 is also provided with a cover 11, the output end of the alternating current motor 13 or the screw for fixing the centrifugal rotating disc 8 is covered in the cover, and the material falling port 6 is arranged in a staggered manner with the cover 11, so as to not only avoid the spat larvae falling into the space between the output end of the alternating current motor 13 and the inner end of the material stirring blade to cause blockage, prevent the rotation of the rotating shaft of the alternating current motor 13, but also effectively prevent the spat larvae from piling up at the center position of the centrifugal rotating disc 8.

[0064] When the material stirring blades on the centrifugal rotating disc 8 are four, the four material stirring blades divide the centrifugal rotating disc 8 into four quadrants, and the application is directly loaded at the rear of a ship or a vehicle during use, at this time, the forward direction of the ship or the vehicle is taken as the Y-axis positive direction for quadrant division, the material falling port 6 corresponds to the second quadrant of the centrifugal rotating disc 8, so as to effectively ensure that the sowing direction of the spat larvae is the Y-axis negative direction, that is, the sowing direction is the stern direction.

[0065] As shown in Figure 1 , Figure 2 , Figure 3 The material containing device includes a material hopper body 2, the material hopper body 2 is fixed on the upper part of the support frame 1, the bottom of the material hopper body 2 is provided with a material outlet 4, and the spat larvae in the material hopper body 2 is sent out of the material hopper body 2 through the material outlet 4; meanwhile, the material outlet 4 and the material falling port 6 are connected with a guide slope 5, the high end of the guide slope 5 is connected with the material outlet 4, and the low end of the guide slope 5 is connected with the material falling port 6, so that the spat larvae sent out through the material outlet 4 enters the material falling port 6 after being guided by the guide slope 5, and the guide slope 5 can buffer the spat larvae before falling from the material falling port 6 to the centrifugal rotating disc 8, so as to effectively avoid the damage of the spat larvae.

[0066] In order to avoid the spat larvae falling on the guide slope 5 directly from both sides of the guide slope 5 in the process of moving downward to the discharge port 6, a baffle can be arranged on both sides of the guide slope 5, so that the guide slope 5 is in a channel shape, without affecting the downward movement of the spat larvae after being discharged from the discharge port 4, so that the spat larvae will not be scattered randomly, and the waste or damage to the spat larvae is reduced.

[0067] The inclination angle of the guide slope 5 is greater than the rest angle of the spat larvae, specifically, the inclination angle of the guide slope 5 is greater than 42°, which can buffer and guide the direction of the spat larvae, and reduce the impact force of the falling of the spat larvae.

[0068] The bottom of the hopper body 2 is closed by the 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 flush with the bottom of the hopper body 2, that is, the discharge port 4 is in a ∩ shape, at this time, the spat larvae 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 the spat larvae are guided by the guide slope 5 and the gravity of the spat larvae themselves, so that the spat larvae move downward along the guide slope 5 and pass through the discharge port 4 to enter the discharge port 6, so that the spat larvae in the hopper body 2 can gradually enter the discharge port 6 in turn, which not only effectively reduces the discharge height, but also effectively reduces the damage degree of the spat larvae.

[0069] As shown in Figure 1 , Figure 2 , Figure 3 The hopper body 2 is further provided with a baffle plate 3 for controlling the opening degree of the discharge port 4, the opening degree of the discharge port 4 is controlled by the baffle plate 3, so as to control the amount of the spat larvae discharged through the discharge port 4, which not only avoids affecting the sowing of the spat larvae due to too much accumulation of the spat larvae on the centrifugal disc 8, but also avoids the sowing density of the spat larvae being too large due to too much accumulation of the spat larvae on the centrifugal disc 8.

[0070] The baffle plate 3 is hingedly installed on the hopper body 2, the distance between the lower end of the baffle plate 3 and the upper surface of the guide slope 5 is changed by rotating the baffle plate 3, so that the amount of the spat larvae passing through the distance is changed, thereby adjusting the opening degree of the discharge port 4. In order to ensure that the baffle plate 3 will not reset due to its own gravity after being rotated by a certain angle, an electric push rod can be directly used to drive the overturning of the baffle plate 3, specifically, the electric push rod is hingedly installed 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 with the baffle plate 3 or hinged through a connecting rod, the baffle plate 3 is overturned by the contraction of the electric push rod, and when the baffle plate 3 is overturned to a certain angle and the electric push rod stops driving, the baffle plate 3 is kept fixed at this time, so that the opening degree of the discharge port 4 is kept after being adjusted.

[0071] Of course, in the present application, in order to keep the opening degree of the discharge port 4 after adjustment, other structures can also be used to achieve, for example, a hook 14 is hinged on the baffle plate 3, and a plurality of hanging rings of different heights are arranged on the hopper body 2. When the baffle plate 3 is turned to a certain angle, the hook 14 can be hung on the corresponding height of the hanging ring. This structure can also make the baffle plate 3 unable to automatically reset after being turned to a certain angle.

[0072] As shown in Figure 1 , Figure 2 , Figure 3 , the hopper body 2 is funnel-shaped, that is, the hopper body 2 has a structure of large upper part and small lower part. In order to increase the capacity of the hopper body 2, a high section can also be added to the upper end of the hopper body 2, and the high section can be a straight cylinder, so that the upper part of the hopper body 2 is a rectangular parallelepiped. The hopper body 2 includes a large slope 21, a small slope 22, and two asymmetric slopes 23. The large slope 21 and the small slope 22 are oppositely arranged, and the two asymmetric slopes 23 are installed between the large slope 21 and the small slope 22. Through the cooperation of the large slope 21, the small slope 22, and the two asymmetric slopes 23, the hopper body 2 forms an inverted four-prism structure with an asymmetric structure. When the spat larvae are stored in the hopper body 2, the spat larvae move downward along the large slope 21 and the small slope 22 by their own gravity, so that the spat larvae can fall from the specified direction in the process of moving downward through the guidance of the large slope 21 and the small slope 22. This not only prevents the spat larvae from being blocked in the hopper body 2 and avoids the spat larvae from arching in the hopper body 2, but also effectively prevents the spat larvae from being damaged in the process of falling. 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 rest angle of the spat larvae.

[0073] As shown in Figure 1 , the support frame 1 is also provided with a cover plate 15, which is horizontally arranged. The height of the cover plate 15 can refer to the height of the present application installed on the ship or vehicle. After the present application is installed on the ship or vehicle, the cover plate 15 needs to be higher than the gunwale of the ship. The centrifugal turntable 8 is installed on the cover plate 15, and the centrifugal turntable 8 can rotate fully on the cover plate 15. A protective cover 7 is also provided on the cover plate 15, and the discharge port 6 extends downward above the centrifugal turntable 8 through the top of the protective cover 7. 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. The longitudinal axis extends from the center of the centrifugal turntable 8 to the front and back of the protective cover 7. At this time, the direction of the ship's travel, the direction of the spat larvae's spreading, and the direction of the longitudinal axis are consistent, and the direction of the spat larvae's spreading is opposite to the direction of the ship's travel. 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 corresponding to the second quadrant of the centrifugal turntable 8 is the second quadrant divided by the longitudinal axis and the transverse axis, as shown in Figure 10 .

[0074] When the application 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. When the centrifugal disc 8 rotates, the spat larvae falling from the centrifugal disc 8 are directly sowed out through the opening of the protective cover 7, so that the spat larvae are sowed out from a fixed direction. Since the dropping port 6 is located in the second quadrant of the centrifugal disc 8, when the spat larvae fall through the dropping port 6 and drop on the centrifugal disc 8, the spat larvae can be immediately sowed out within the opening range of the protective cover 7 in cooperation with the rotation of the centrifugal disc 8, so that the spat larvae will not hit the inner wall of the protective cover 7 after being sowed out through the centrifugal disc 8, that is, the spat larvae will not be damaged.

[0075] Meanwhile, the horizontal straight distance between the center of the dropping port 6 and the center of the centrifugal disc 8 is l, and the angle between the horizontal straight line connecting the center of the dropping port 6 and the center of the centrifugal disc 8 and the horizontal axis is θ. As shown in Figure 11 When θ is 45° and the dropping port 6 is a circular port with a diameter of 18 m, three points with l of 12 cm, 15 m and 18 m are simulated, and it is obtained that the farther the dropping port is from the center of the centrifugal disc, the more the sowing direction is forward, so that the point with l of 18 cm is taken as the optimal center of the dropping port. In addition, as shown in Figure 12 When the point with l of 18 cm is taken as the dropping port, θ is selected from 30° to 75° at an interval of 15°, and it is obtained that with the increase of θ, the position of the dropping port gradually shifts from the left to the right, and the sowing direction is optimal when θ is 60°.

[0076] As shown in Figure 5 The left and right sides of the protective cover 7 are asymmetric structures. It is to be noted that the left and right sides of the protective cover 7 are based on the opening direction of the protective cover 7. The left and right sides of the protective cover 7 are inclined surfaces, and the inclined angles of the left and right sides of the protective cover 7 are different, so that the opening width of the protective cover 7 is greater 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 the sowing of the spat larvae to the front, but also keeps the sowing width of the spat larvae fixed.

[0077] The inclined angles of the left and right sides of the protective cover 7 are 125° and 110° respectively, so that the spat larvae sowed out through the centrifugal disc 8 can be as little blocked as possible in the limited space during the rotation of the centrifugal disc 8, and the spat larvae can be prevented from hitting the rear of the protective cover 7 as much as possible, so that the sowing angle of the spat larvae from the dropping port 6 is about 120°.

[0078] The support frame 1 is further provided with a hook 14. Since the present application is installed on a ship or a vehicle in use, and is not hung on the outside of the ship or the vehicle, the hook 14 is directed outward after installation, 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 present application is installed on the edge of the ship or the vehicle, the support frame 1 can be hung on the ship rail or the vehicle through the hook 14, so that the installation of the present application is more stable.

[0079] In the present application, in order to make the appearance more simple, a cover can also be arranged on three sides of the support frame 1 or four sides of the support frame 1. When the cover only closes 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 closes four sides of the support frame 1, in order to ensure that the spat larvae can be normally sowed out of the opening on the protective cover 7, a hole corresponding to the opening on the protective cover 7 should also be arranged on the cover of the support frame 1 to avoid affecting the sowing of the spat larvae.

[0080] In order to conveniently send the spat larvae into the hopper body 2, a lifting machine for lifting the spat larvae can also be arranged, which can be a bucket elevator, a Boston ivy, a conveyor belt, etc., so that the spat larvae can be automatically sent into the hopper body 2, and the manual labor can be greatly reduced.

[0081] In order to reduce the damage to the spat larvae as much as possible, the parts in contact with the spat larvae in the present application can be directly made of EVA material or coated with an EVA shock-absorbing material layer, such as the inner wall of the hopper body 2, the guide slope 5, the baffle plate 3, the centrifugal disc 8, the material stirring blade, the cover 11, and the protective cover 7. After the parts in contact with the spat larvae are treated by using the EVA material, the breakage rate of the spat larvae can be reduced as much as possible. The damage rate of the spat larvae under different materials and different heights is tested as shown in Table 1.

[0082] Table 1 is the damage rate of the spat larvae under different materials and different heights Through the test, the damage rate of the spat larvae on each part made of EVA material or coated with an EVA shock-absorbing material layer is 0 when the material falling height is within 1000 mm. Through the test, the rest angle of the spat larvae on the EVA shock-absorbing material layer is 15°.

[0083] At the same time, through calculation, the relationship between the material falling quality and the opening degree of the material falling port of the spat larvae is:

[0084] y = 89.91x + 18.91x - 9.70 2

[0085] ​Wherein, y is the material quality in an hour, unit is ton, x is the opening of the material outlet (0 is the minimum opening, indicating the closed state, 1 is the maximum opening 100%, because the 0-0.25 opening will form a blockage, so the opening range of the material outlet of the device is 0.25-1.

[0086] When it is needed to use the application to seed the shellfish, the application is installed at the rear end of the shallow sea ship or the rear end of the beach vehicle, and is hung on the ship rail of the ship or the vehicle through the hook 14, the shellfish is lifted and sent into the hopper body 2 through the elevator, the material outlet 4 on the hopper body 2 is opened by rotating the material blocking plate 3, the shellfish in the hopper body 2 enters the guide slope 5 through the material outlet 4, and moves downward along the guide slope 5, and finally falls on the centrifugal disc 8 through the material outlet 6; at the same time, the AC motor 13 is started in the process that the shellfish is lifted by the elevator, the centrifugal disc 8 is driven to rotate by the AC motor 13, and when the shellfish falls on the centrifugal disc 8, the shellfish is quickly scattered out through the opening on the protective cover 7 by the rotation of the centrifugal disc 8, so that the seeding is realized. In the application, the running path of the shallow sea ship or the beach vehicle when the shellfish is seeded is as shown in the figure. Figure 9

[0087] The application can be applied to the seeding of various shellfish; meanwhile, the controller, the power meter, the display screen and other electrical elements can be arranged in the application, at this time, the power meter input end is connected with the AC motor output end, the power meter can display the power of the AC motor, the controller and the display screen are bidirectionally connected, the electric push rod input end and the AC motor input end are connected with the controller output end, and the display screen can not only display the parameters such as the rotation speed of the AC motor, the opening of the material outlet, the state of the electric push rod and the power of the AC motor, but also input the parameters such as the rotation speed of the AC motor and the opening of the material outlet to the controller through the display screen.
