Description

Adjustable feeding and feeding equipment and its operation method This disclosure relates to a feeding device and its operating method, and more particularly to an adjustable feeding device and its operating method that can adjust the amount of feed fed according to received instructions, so that farmers can reduce manpower and lower labor costs. Generally, fish farmers manually scatter feed when feeding fish in their aquaculture farms. This allows them to continuously observe the fish's location and feeding behavior, adjusting the amount of feed scattered each time. However, it's clear that this technique of observing the fish's feeding behavior and adjusting the feeding amount requires manual observation and feeding, which not only increases labor costs in aquaculture but also further reduces the efficiency of feeding fish. One of the technical features disclosed herein is an adjustable feeding device that can adjust the amount of aquaculture feed thrown out by the turntable by adjusting the speed of the control motor, replacing the traditional method of manually observing the feeding behavior of the fish and changing the feeding amount. This can reduce the use of manpower, reduce labor costs, and further improve feeding efficiency. This disclosed embodiment provides an adjustable feeding device for discharging aquaculture feed into an aquaculture area. The device includes a feed storage tank, an adjustable feeding device, and a directional discharging device. The feed storage tank stores the aquaculture feed. The adjustable feeding device has a top cover, a turntable, a fixed base, and an adjustable motor disposed within the fixed base. The top cover is positioned above the turntable, which is located within the annular wall of the fixed base and connected to the adjustable motor. The first diameter of the feed inlet of the top cover is smaller than the second diameter of the turntable, and the second diameter of the turntable is smaller than the third diameter of the annular wall. When the aquaculture feed falls through the feed inlet of the top cover onto the turntable, the adjustable motor drives the turntable to rotate, causing the feed to be transferred to the hollow area between the annular wall and the adjustable motor by the centrifugal force generated by the turntable's rotation. The discharge device is located on the side of the adjustable feed device facing away from the feed storage tank, and has a discharge pipe and an exhaust fan located on one side of the discharge pipe. When the aquaculture feed falls through the perforated area into the discharge pipe, the exhaust fan is used to blow the aquaculture feed out of the discharge pipe and deliver it to the aquaculture area. According to one embodiment of this disclosure, the top cover, turntable, and control motor are aligned in the vertical direction, and the top cover and turntable are separated in the vertical direction. According to one embodiment of the present disclosure, the aforementioned fixing seat has a fixing part and four connecting parts located around the fixing part and connected to the annular wall. The regulating motor is locked to the fixing part, and the regulating motor is located at the center of the annular wall via the four connecting parts and the fixing part. According to one embodiment of the present disclosure, the aforementioned control motor has a rotating part, and the fixing part of the fixing member has a rotating hole, with the rotating part extending out of the rotating hole to connect to the turntable. According to one embodiment of this disclosure, the adjustable feeding device has a receiving member disposed on the side of the fixed base opposite to the top cover, and the receiving member is used to receive the aquaculture feed falling from the hollow area and to transfer the aquaculture feed to the discharge pipe of the discharge device. According to one embodiment of the present disclosure, the receiving member has a snap-fit ​​portion, and the bottom of the annular wall of the fixing member abuts against the snap-fit ​​portion to secure the fixing member and the receiving member. According to one embodiment of the present disclosure, the adjustable feeding device has an anti-backflow component, which is disposed in the receiving component and extends into the discharge pipe of the discharging device. According to one embodiment of this disclosure, the aforementioned anti-backflow component has a lateral opening through which the aquaculture feed falls into the discharge pipe of the discharge device. According to one embodiment of the present disclosure, the aforementioned anti-backflow component has a lateral anti-wind portion, which is disposed on the side of the anti-backflow component facing the exhaust fan of the discharge device. The lateral anti-wind portion is used to prevent the air blown out by the exhaust fan from sending the aquaculture feed back into the receiving component. The lateral opening of the anti-backflow component faces the outlet end of the discharge pipe away from the exhaust fan, while the lateral anti-wind portion of the anti-backflow component faces the exhaust fan. According to one embodiment of the present disclosure, the top cover is provided with a fixing seat facing the side of the feed storage tank and abuts against the top of the fixing seat and contacts the feed storage tank, and the top cover has an annular portion that tapers toward the feed inlet. According to one embodiment of this disclosure, the aforementioned control motor has a remote controller, which is used to control the speed of the control motor and the start switch. Another embodiment disclosed herein is an operating method for an adjustable feeding device, which can adjust the amount of aquaculture feed thrown out by the turntable by adjusting the speed of the control motor, replacing the traditional method of manually observing the feeding behavior of the fish and changing the feeding amount. This can reduce the use of manpower, reduce labor costs, and further improve feeding efficiency. The disclosed embodiments provide an operating method for an adjustable feeding device used to deliver aquaculture feed to an aquaculture area. The operating method includes: storing aquaculture feed in a feed storage tank; receiving the feed through a top cover of the adjustable feeding device, causing the feed to fall through a feed hole in the top cover onto a turntable of the adjustable feeding device, wherein the top cover is positioned above the turntable, the turntable is disposed within the annular wall of a fixed base of the adjustable feeding device and connected to an adjustable motor, the first diameter of the feed hole in the top cover is smaller than the second diameter of the turntable, and the second diameter of the turntable is smaller than the third diameter of the annular wall; and rotating the turntable using the adjustable motor of the adjustable feeding device, causing the centrifugal force generated by the rotation of the turntable to transfer the feed to a hollow area between the annular wall and the adjustable motor, wherein the adjustable motor is disposed within the fixed base. According to one embodiment of the present disclosure, the above-mentioned operation method further includes: receiving aquaculture feed falling from the hollow area through the discharge pipe of the discharge device; and blowing the aquaculture feed out of the discharge pipe and discharging it into the aquaculture area through the exhaust fan of the discharge device, wherein the exhaust fan is arranged on one side of the discharge pipe. According to one embodiment of the present disclosure, the above-mentioned operating method further includes using the lateral wind-resistant part of the anti-backflow component of the adjustable feeding device to prevent the air blown by the exhaust fan from returning the aquaculture feed to the receiving part of the adjustable feeding device, wherein the receiving part is provided on the side of the fixed base opposite to the top cover, and the lateral wind-resistant part is provided on the side of the anti-backflow component facing the exhaust fan. According to one embodiment of this disclosure, the aforementioned aquaculture feed falls into the discharge pipe of the discharge device through the lateral opening of the anti-backflow component. In summary, in this disclosure, the first diameter of the feed hole on the top cover of the adjustable feeding device of the adjustable feeding equipment is smaller than the second diameter of the turntable. Therefore, the feed can fall precisely above the turntable. The second diameter of the turntable is smaller than the third diameter of the annular wall. Thus, when the feed falls through the feed hole on the top cover above the turntable, the control motor drives the turntable to rotate, allowing the feed to be transferred by the centrifugal force generated by the turntable's rotation into the hollow area between the annular wall and the turntable. After falling through the hollow area into the discharge pipe, the exhaust fan blows the feed out of the discharge pipe and into the aquaculture area. Furthermore, when the adjustable feeding equipment receives a command indicating that the fish are beginning to gather, the speed of the control motor can be increased to increase the amount of feed thrown out by the turntable, thereby increasing the overall feeding amount. When the adjustable feeding equipment receives a command indicating that the fish are beginning to disperse, the speed of the control motor can be decreased to decrease the amount of feed thrown out by the turntable, thereby decreasing the overall feeding amount. In this way, fish farmers who use adjustable feeding equipment can replace the traditional method of manually observing the fish's feeding behavior to adjust the amount of feed, thereby reducing the use of manpower, lowering labor costs, and further improving feeding efficiency. The following disclosure of embodiments provides many different implementations, or examples, for carrying out various features of the provided object.

The adjustable feeding device 100 includes a feed storage tank 110, an adjustable feeding device 120, and a discharging device 130. The feed storage tank 110 can store the livestock feed 200 therein. The adjustable feeding device 120 can receive the livestock feed 200 and transfer it to the discharging device 130. The discharging device 130 can deliver the livestock feed 200 into the livestock area 300. Please refer to Figures 4 to 6. Figure 4 shows an exploded view of an adjustable feeding device 120 according to an embodiment of the present disclosure, Figure 5 shows a side view of an adjustable feeding device 120 according to an embodiment of the present disclosure, and Figure 6 shows a cross-sectional view of the adjustable feeding device 120 of Figure 5 along line segment AA. In Figures 4 to 6, the adjustable feeding device 120 includes a top cover 122, a turntable 124, a fixed base 126, and an adjustable motor 128 disposed in the fixed base 126. The top cover 122 is disposed above the turntable 124, which is disposed within the annular wall 127 of the fixed base 126 and connected to the adjustable motor 128. It is worth noting that the first diameter distance R1 of the feed hole H1 of the top cover 122 is smaller than the second diameter distance R2 of the turntable 124, and the second diameter distance R2 of the turntable 124 is smaller than the third diameter distance R3 of the annular wall 127. When the feed 200 falls through the feed hole H1 of the top cover 122 onto the turntable 124, the control motor 128 can drive the turntable 124 to rotate, so that the feed 200 is transferred to the hollow area A between the annular wall 127 and the control motor 128 by the centrifugal force generated by the rotation of the turntable 124. In some embodiments, the fixing seat 126 has a fixing part B1 and four connecting parts B2 located around the fixing part B1 and connected to the annular wall 127. The regulating motor 128 is locked to the fixing part B1. The regulating motor 128, via the four connecting parts B2 and the fixing part B1, is located at the center of the annular wall 127, allowing the feed 200 to fall to the outer perimeter not obstructed by the regulating motor 128, i.e., the open area A. The regulating motor 128 has a rotating part 129, and the fixing part B1 of the fixing seat 126 has a rotating hole H2. The rotating part 129 extends beyond the rotating hole H2 to connect to the turntable 124, thereby driving the turntable 124 to rotate. In some embodiments, the top cover 122 is provided with a fixing seat 126 facing the feed storage tank 110 and abuts against the top of the fixing seat 126 and contacts the feed storage tank 110. The top cover 122 has an annular portion D, which tapers towards the feed inlet H1, allowing the feed inlet H1 of the top cover 122 to collect the livestock feed 200 above the turntable 124. The regulating motor 128 has a remote controller E, which can control the rotation speed of the regulating motor 128 and activate the switch to change the amount of livestock feed 200 thrown out by the turntable 124. The remote controller E can adjust the feeding amount of livestock feed 200 according to the current situation. Please refer to Figures 6 to 8. Figure 7 illustrates a schematic diagram of the transfer of aquaculture feed 200 from an adjustable feeding device 120 to a discharging device 130 according to an embodiment of this disclosure. Figure 8 illustrates a schematic diagram of the discharging of aquaculture feed 200 into an aquaculture area 300 by an adjustable feeding device 100 according to an embodiment of this disclosure. In Figures 6 to 8, the adjustable feeding device 120 has a receiving member 121, which is disposed on the side of the fixed base 126 opposite to the top cover 122. The receiving member 121 is used to receive the aquaculture feed 200 falling from the hollow area A and transfer the aquaculture feed 200 to the discharge pipe 132 of the discharging device 130. The receiving member 121 has a latching part 123, and the bottom of the annular wall 127 of the fixed base 126 abuts against the latching part 123 to secure the fixed base 126 and the receiving member 121. Furthermore, the top cover 122, the turntable 124, and the control motor 128 are aligned in the vertical direction V, and the top cover 122 and the turntable 124 are separated in the vertical direction V. In some embodiments, the adjustable feeding device 120 has an anti-backflow component 125, which is disposed in the receiving device 121 and extends into the discharge pipe 132 of the discharging device 130. The anti-backflow component 125 has a lateral opening O through which the feed 200 falls into the discharge pipe 132 of the discharging device 130. The anti-backflow component 125 also has a lateral wind-resistant portion C, which is disposed on the side of the anti-backflow component 125 facing the exhaust fan 134 of the discharging device 130. The lateral wind-resistant portion C prevents the air blown by the exhaust fan 134 from sending the feed 200 back into the receiving device 121. Specifically, the lateral opening O of the anti-backflow component 125 faces the end of the discharge pipe 132 away from the outlet of the exhaust fan 134, while the lateral wind-resistant portion C of the anti-backflow component 125 faces the exhaust fan 134. When the feed 200 falls into the discharge pipe 132 through the lateral wind-resistant part C and the lateral opening O of the anti-backflow component 125, the exhaust fan 134 blows the feed 200 out of the discharge pipe 132, creating a reverse backflow. The configuration of the lateral wind-resistant part C and the lateral opening O of the anti-backflow component 125 improves the backflow effect, effectively preventing the feed 200 from being blown back into the adjustable feeding device 120. Furthermore, the discharge device 130 is located on the side of the adjustable feeding device 120 opposite to the feed storage tank 110, and the discharge device 130 has a discharge pipe 132 and an exhaust fan 134 located on one side of the discharge pipe 132. After the feed 200 falls into the discharge pipe 132 through the perforated area A, the exhaust fan 134 blows the feed 200 out of the discharge pipe 132 to deliver it to the breeding area 300. The following description will explain the operation of the adjustable feeding device. The connections, materials, and functions of the components already described will not be repeated, but will be stated in advance. Please refer to Figure 9, which illustrates a flowchart of the operation method of an adjustable feeding device according to an embodiment of the present disclosure. The operation method of the adjustable feeding device includes the following steps. The operation method of the adjustable feeding device is used to feed livestock feed into a livestock farm. First, in step S1, livestock feed is stored in a feed storage tank. Next, in step S2, the top cover of the adjustable feeding device receives the livestock feed, causing it to fall through the feed hole of the top cover onto the turntable of the adjustable feeding device. The top cover is positioned above the turntable, which is located within the annular wall of the fixed seat of the adjustable feeding device and connected to an adjustable motor. The first diameter of the feed hole of the top cover is smaller than the second diameter of the turntable, and the second diameter of the turntable is smaller than the third diameter of the annular wall. Next, in step S3, the adjustable motor of the adjustable feeding device drives the turntable to rotate, causing the livestock feed to be transferred to the hollow area between the annular wall and the adjustable motor by the centrifugal force generated by the rotation of the turntable. The adjustable motor is located within the fixed seat. The steps described above will be explained in detail in the following description. Referring to Figures 6 to 8, the feed storage tank 110 can store livestock feed 200 therein. Next, the top cover 122 of the adjustable feeding device 120 receives the livestock feed 200, allowing it to fall through the feed hole H1 of the top cover 122 onto the turntable 124 of the adjustable feeding device 120. Because the first diameter distance R1 of the feed hole H1 of the top cover 122 of the adjustable feeding device 120 is smaller than the second diameter distance R2 of the turntable 124, the livestock feed 200 can fall precisely above the turntable 124. Next, the controllable motor 128 of the adjustable feeding device 120 can be driven to rotate the turntable 124, so that the feed 200 is transferred to the hollow area A between the annular wall 127 and the controllable motor 128 by the centrifugal force generated by the rotation of the turntable 124. Since the second diameter distance R2 of the turntable 124 is smaller than the third diameter distance R3 of the annular wall 127, when the feed 200 falls above the turntable 124 through the feed hole H1 of the top cover 122, the controllable motor 128 can drive the turntable 124 to rotate, so that the feed 200 can be transferred to the hollow area A between the annular wall 127 and the turntable 124 by the centrifugal force generated by the rotation of the turntable 124. Next, the discharge pipe 132 of the discharge device 130 can receive the livestock feed 200 falling from the hollow area A. Furthermore, the exhaust fan 134 of the discharge device 130 can blow the livestock feed 200 out of the discharge pipe 132 for distribution to the breeding area 300. In addition, the lateral wind-resistant portion C of the anti-backflow member 125 of the adjustable feed device 120 can prevent the air blown by the exhaust fan 134 from returning the livestock feed 200 to the receiving member 121 of the adjustable feed device 120. The receiving member 121 is located on the side of the fixed base 126 facing away from the top cover 122, and the lateral wind-resistant portion C is located on the side of the anti-backflow member 125 facing the exhaust fan 134. Furthermore, the livestock feed 200 can fall into the discharge pipe 132 of the discharge device 130 through the lateral opening O of the anti-backflow member 125. Specifically, when the adjustable feeding device 100 receives a command indicating that the fish are beginning to gather, it can increase the speed of the control motor 128 to increase the amount of feed 200 thrown out by the turntable 124, thereby increasing the overall feeding amount. When the adjustable feeding device 100 receives a command indicating that the fish are beginning to disperse, it can decrease the speed of the control motor 128 to decrease the amount of feed 200 thrown out by the turntable 124, thereby decreasing the overall feeding amount. In this way, fish farmers using the adjustable feeding device 100 can replace the traditional method of manually observing the fish's feeding behavior to adjust the feeding amount, reducing manpower, lowering labor costs, and further improving feeding efficiency. The foregoing outlines the features of several embodiments to enable those skilled in the art to better understand the nature of this disclosure.
