Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1-4This utility model provides a technical solution: a feeding structure, including a support 110 and a feeding pipe 121 for feeding a screening box 120. The support 110 is L-shaped and a first support frame 130 is rotatably mounted on one side of its inner wall. An adjustment component is installed on one side of the first support frame 130, and feeding boxes 131 are symmetrically fixedly mounted on the other side of the first support frame 130. Feeding pipes 132 and discharge pipes 133 are respectively installed on the side of the two feeding boxes 131 that are relatively close to each other. A sealing cap is threaded on the feeding pipe 132, and a valve is installed on the discharge pipe 133. The screening box 120 is fixedly installed at the bottom of the inner wall of the support 110, and a feeding hole matching the feeding pipe 121 is provided at the top of the screening box 120. The feeding pipe 121 is slidably connected to the inner wall of the feeding hole and is equipped with a lifting component. A conveying pipe 122 is fixedly installed on one side of the feeding pipe 121, and the top end of the conveying pipe 122 is slidably sleeved on the discharge pipe 133.

[0021] In some specific implementations, a second support frame 134 is fixedly installed on one side of each of the two feed boxes 131. A reinforcing frame 135 is symmetrically fixed between the two ends of the first support frame 130 and the second support frame 134. The reinforcing frame 135 is U-shaped, with the first support frame 130 and the second support frame 134 symmetrically arranged on both sides of the feed box 131. The U-shaped reinforcing frame 135 connects the two ends of the first support frame 130 and the second support frame 134, further enhancing the rigidity of the overall structure. This effectively resists the stress generated when the feed box 131 rotates or holds materials, preventing structural deformation and extending the service life of the device.

[0022] In some specific implementations, the conveying pipe 122 is a rigid pipe and is inclined, with the discharge pipe 133 slidably connected to the inner wall of the conveying pipe 122. This ensures that the material can flow smoothly under its own weight during the conveying process, reducing residue and blockage. The slidable connection between the discharge pipe 133 and the inner wall of the conveying pipe 122 ensures the sealing of the connection between the two, preventing material leakage, and also allows for relative displacement when the feed box 131 rotates or the discharge pipe 121 rises or falls, without affecting the connectivity of the material conveying channel and ensuring the continuity of the feeding process.

[0023] In some specific implementations, a limiting ring 136 is fixedly installed on one side of the feed box 131. The cross-section of the limiting ring 136 is T-shaped, and an annular groove matching the limiting ring 136 is provided on one side of the bracket 110. The limiting ring 136 is slidably connected to the inner wall of the annular groove. This serves to limit and guide the rotation of the feed box 131, preventing axial displacement or detachment during rotation. At the same time, the T-shaped structure ensures the stability of the connection, allowing the feed box 131 to maintain a stable posture when filling with materials or rotating, thus improving the safety of the device operation.

[0024] Please see Figure 4The lifting assembly includes a support ring 140 and an electric push rod 141. The support ring 140 is fixedly installed on the top outer side of the pouring pipe 121, and the electric push rod 141 is fixedly installed on the top of the screening box 120. The output end of the electric push rod 141 is fixedly connected to the bottom end of the support ring 140. This enables convenient adjustment of the height of the pouring pipe 121. The structure is simple to operate and precise to control, and can quickly adjust the position of the pouring pipe 121 and the conveying pipe 122 to adapt to the rotation state of the feeding box 131, ensuring that the conveying pipe 122 and the discharge pipe 133 always maintain an effective connection.

[0025] In some specific implementations, guide rods 142 are symmetrically fixedly installed at the top of the screening box 120, and support rings 140 are slidably installed on the guide rods 142. The guide rods 142 are symmetrically arranged on both sides of the pouring pipe 121. This effectively prevents the pouring pipe 121 from shifting or shaking during the lifting process, ensuring that the pouring pipe 121 always moves in a vertical direction. This not only improves the accuracy of the fit between the pouring pipe 121 and the feed hole of the screening box 120, but also reduces frictional wear between components, and improves the stability and reliability of the lifting assembly.

[0026] Please see Figure 5 The adjustment assembly includes a servo motor 150, a rotating shaft 151, and a support shaft 152. The support shaft 152 is rotatably mounted on one side of the bracket 110. A worm gear is fixedly mounted on one end of the support shaft 152. A horizontal plate 153 is fixedly mounted between the two sides of the inner wall of the first support frame 130. The other end of the support shaft 152 passes through the bracket 110 and is fixedly connected to one side of the horizontal plate 153. Side plates 154 are symmetrically fixedly mounted on one side of the bracket 110. A rotating shaft 151 is rotatably mounted between the two side plates 154. The servo motor 150 is mounted on one end of the rotating shaft 151, and a worm gear is fixedly mounted on the rotating shaft 151. The worm gear is connected to the worm gear drive. The servo motor 150 is fixedly mounted on one side of the side plate 154, and the output end of the servo motor 150 passes through the side plate 154 and is fixedly connected to one end of the rotating shaft 151. This ensures the stability of the transmission process, making the rotation operation of the feed box 131 convenient and reliable, and meeting the needs of different feeding positions.

[0027] This utility model embodiment also provides a breeding screening device, including the above-mentioned feeding structure and screening screen. The screening screen is installed in the screening box 120, realizing the integrated operation of feeding and screening, and improving the overall efficiency and automation of breeding screening operations.

[0028] Working principle: The breeding material to be screened is put into the feeding box 131 through the feeding pipe 132. After feeding is completed, the feeding pipe 132 is sealed with a sealing cover. The servo motor 150 is started to drive the rotating shaft 151 to rotate. The rotation of the rotating shaft 151 drives the support shaft 152 to rotate through the cooperation of the worm gear and worm. The rotation of the support shaft 152 drives the feeding box 131 to rotate 180° through the cooperation of the horizontal plate 153 and the first support frame 130. When the feeding box 131 is full of seeds and rotates to the top, the electric push rod 141 is started to drive the support ring 140 to move upward. The upward movement of the support ring 140 drives the conveying pipe 122 through the pouring pipe 121 to connect with the discharge pipe 133 of the upper feeding box 131. At this time, the valve can be opened to start feeding.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
