During feed preparation, various feed ingredients need to be added to a mixing tank in specific proportions. Due to the large production volume, the mixing tank is also quite large. To pour the feed ingredients into the mixing tank, it is necessary to manually move the feed ingredients to a high place, then open the packaging and pour the feed into the mixing tank. To be able to stand at a high place to pour the feed ingredients, it is necessary to... A platform is built around the mixing tank, but the top of the mixing tank is exposed to facilitate the placement of raw materials inside. People stand around the mixing tank to pour materials, and if they lose their balance, they may fall into the mixing tank.

[0078] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0079] Example 1, please refer to Figures 1 to 12An automatic feed feeding device includes a mixing tank 1, with a stirring assembly 2 inside. It also includes a feeding hopper 3, a screw conveyor 4, a lifting and lowering feeding rack, a track 5, a bag-retrieving assembly, a positioning assembly, and a bag-breaking assembly. Multiple feeding hoppers 3 are provided and positioned on one side of the mixing tank 1. Different feed ingredients are placed in the feeding hoppers 3 and transported into the mixing tank 1 by the screw conveyor 4. This allows for quantitative feeding of different feed ingredients, reducing the problem of inaccurate feeding caused by pre-mixing. The screw conveyor 4 is positioned between the mixing tank 1 and the feeding hoppers 3. The input end of the screw conveyor 4 is connected to the feeding hopper 3, and the output end of the screw conveyor 4 points to the top of the mixing tank 1. By using the screw conveyor 4 to feed the feed ingredients, the dangers of manual height work are reduced, and the risk of people falling into the mixing tank 1 is avoided, improving feeding safety. The feeding rack is installed on one side of the feeding hopper 3. Bagged feed ingredients can be stacked on the rack. A positioning component determines the height of the rack to suit the bag-retrieving component, improving automation. Tracks 5 are arranged on both sides of the feeding hopper 3 and the feeding rack. The bag-retrieving component is mounted on tracks 5 via a drive mechanism, allowing it to move between the rack and the feeding hopper 3. This facilitates moving feed from the rack to the top of the feeding hopper 3 when it reaches the bag-retrieving component's height. A positioning component is located on one side of track 5 to control the height of the rack. A bag-breaking component is installed in the middle of the inner wall of the feeding hopper 3, near the rack. This component breaks the bottom of the bagged feed as it moves into the feeding hopper 3, releasing the feed into the hopper 3. Finally, the feed is conveyed to the mixing tank 1 via a screw conveyor 4, improving automation and achieving automatic feeding.

[0080] Accordingly, the material rack includes: a material rack 6, a base plate 7, a lower hinge seat 8, an upper hinge seat 9, a lower sliding groove 10, an upper sliding groove 11, a first support rod 12, a second support rod 13, and a hydraulic cylinder 14. The base plate 7 is located below the material rack 6. The lower hinge seat 8 is installed on the base plate 7 on the side away from the feeding hopper 3. The upper hinge seat 9 is located directly above the lower hinge seat 8 and is connected to the bottom end of the material rack 6. The lower sliding groove 10 is installed on the base plate 7 on the side near the feeding hopper 3. The upper sliding groove 11 is located directly above the lower sliding groove 10 and is connected to the bottom end of the material rack 6. One end of the first support rod 12 is rotatably mounted on the lower hinge seat 8 via a lower pivot, and the other end of the first support rod 12 is slidably mounted on the upper sliding shaft. Inside the upper slide groove 11, one end of the second support rod 13 is rotatably mounted on the upper hinge seat 9 via the upper rotating shaft, and the other end of the second support rod 13 is slidably disposed inside the lower slide groove 10 via the lower slide shaft. The middle parts of the first support rod 12 and the second support rod 13 are rotatably connected by a shaft. The hydraulic cylinder 14 is horizontally mounted on the base plate 7, and the output end of the hydraulic cylinder 14 is provided with a drive sleeve, which is sleeved on the outside of the lower slide shaft. There are at least two hydraulic cylinders 14. Through the extension and retraction of the hydraulic cylinders 14, the upper slide shaft and the lower slide shaft can be driven to slide laterally inside the upper slide groove 11 and the lower slide groove 10 respectively, thereby realizing the angle change between the first support rod 12 and the second support rod 13, and realizing the height adjustment of the material plate 6.

[0081] Furthermore, the track 5 is I-shaped, and the upper width of the top of the track 5 is smaller than the lower width of the track 5. A rack 15 is provided on the outer side of the track 5. The bag-grabbing assembly includes: a sliding plate 16, a drive motor 17, and a bag-clamping structure. The sliding plate 16 is slidably mounted on the track 5, and the bottom end of the sliding plate 16 is provided with a groove that matches the track 5. Through the cooperation between the groove and the track 5, the sliding plate 16 can move along the direction of the track 5. The bottom end of the track 5 is provided with bolt mounting holes, and the track 5 can be fixed to the ground by using collision bolts. The drive motor 17 is located on the outer side of the sliding plate 16, and a drive gear is installed at the output end of the drive motor 17. The drive gear meshes with the rack 15. The bag-clamping structure is located on the top of the sliding plate 16. By controlling the forward and reverse rotation of the drive motor 17, the drive gear rotates in both directions. Under the meshing action of the drive gear and the rack 15, the sliding plate 16 moves along the direction of the track 5.

[0082] As a further technical solution of this application, the bag clamping structure includes: a mounting plate 18, a transmission belt 19, a conveyor shaft 20, an annular cavity 21, springs 22, and a drive motor 23. The mounting plate 18 is located at the top of the sliding plate 16 and is L-shaped. The concave surface of the mounting plate 18 points towards the feeding hopper 3. Two sets of transmission belts 19 are symmetrically arranged on the inner side of the mounting plate 18, and the contact surfaces of the two transmission belts 19 are pressed together. The outer surface of the transmission belts 19 is provided with anti-slip texture. Each transmission belt 19 is connected by two conveyor shafts 20, and the conveyor shafts 20 are rotatably connected to the mounting plate 18. An annular cavity 21 is provided inside the transmission belt 19, and multiple springs 22 are evenly distributed inside the annular cavity 21 to drive the motor 23. The motor 23 is installed on the outside of the mounting plate 18, and the output end of the motor 23 passes through the mounting plate 18 and is connected to one of the transmission shafts 20. By rotating the motor 23, one of the transmission shafts 20 is rotated, thereby driving the corresponding transmission belt 19 to rotate. Since the contact surfaces of the two transmission belts 19 are pressed against each other, and the outer surface of each transmission belt 19 is provided with anti-slip texture, the two transmission belts 19 on the same side can rotate in opposite directions at the same time, thereby achieving the purpose of clamping the edge of the bagged feed. By setting a spring 22 inside the annular cavity 21, the elasticity of the transmission belt 19 is enhanced, that is, the squeezing effect between the two transmission belts 19 is improved, thus improving the clamping effect on the edge of the bagged feed packaging bag.

[0083] Correspondingly, the bag-breaking assembly includes an extension rod 24 and a blade 25. The extension rod 24 is connected to the inner wall of the feeding hopper 3, and the blade 25 is installed on the top of the other end of the extension rod 24. Additionally, the positioning assembly includes a positioning rod 26 and a position sensor 27. The positioning rod 26 is longitudinally installed on the outer end of the track 5, and the position sensor 27 is installed on the upper side of the positioning rod 26, with its probe pointing upwards towards the feeding rack. The height of the position sensor 27 is flush with the contact surface between the two drive belts 19 on the mounting plate 18. The extension rod 24 ensures that the bagged feed begins to contact the blade 25 when it has partially entered the feeding hopper 3, preventing the bagged feed from contacting the blade before reaching the feeding hopper 3. The bag begins to break and leak material. Through the action of the blade 25, as the bagged feed moves along the direction of the track 5, the bottom of the bag is completely cut open, so that the feed falls into the feeding hopper 3 from the bottom, achieving the purpose of automatic material storage. The position sensor 27 is connected to the hydraulic cylinder 14. A signal receiver that can receive the signal emitted by the position sensor 27 is installed on the hydraulic cylinder 14. When the height of the stacked bagged feed reaches the height of the position sensor 27, the hydraulic cylinder 14 is controlled to stop working. At this time, the edge of the bagged feed packaging bag can just reach the contact surface between the two transmission belts 19. Thus, after each bag of feed is used up, the subsequent feed can be positioned, clamped, and broken to store material.

[0084] Based on the aforementioned scheme, it also includes: a support frame 28, which is disposed inside the transmission belt 19 and contacts the inner wall of the transmission belt 19. The support frame 28 is fixedly connected to the mounting plate 18 and rotates with the transmission shaft 20. The support frame 28 improves the clamping effect between two adjacent transmission belts 19. It also includes a layered plate 34, the top of the feeding hopper 3 is lower than the height of the mounting plate 18, and the layered plate 34 is connected to the side wall of the feeding hopper 3 near the feeding rack through the support plate 35. The layered plate 34 is arranged in parallel, and the end of the layered plate 34 away from the support plate 35 is pointed. The layered plate 34 prevents the bag clamping structure from moving the lower bag of feed under the action of friction after clamping the uppermost bag of feed, thereby improving the accuracy and stability of each bag of feed being clamped.

[0085] Example 2, this example is based on Example 1, please refer to... Figures 11 to 12 It also includes a bag-cutting assembly, which is longitudinally positioned on the inner wall of the feeding hopper 3 on the side opposite to the blade 25. The bag-cutting assembly includes an arc-shaped frame 29, in which an electric heating wire 30 is longitudinally connected. A collection box 31 is provided on the side of the track 5 near the screw conveyor 4. After the feed has basically fallen completely into the feeding hopper 3, the empty bag continues to move backward along the track 5 under the action of the bag clamping structure. At this time, the empty bag touches the electric heating wire 30 and is cut into two halves. Through the rotation of the transmission belt 19, each part of the empty bag is thrown outward and collected by the collection box 31. This system integrates feed bag clamping, storage, and bag collection, improving the on-site environment. To enhance the adaptability of the clamping structure to feed bags of varying widths, the mounting plate 18 and sliding plate 16 are fitted together in a sliding fit in this embodiment. An L-shaped bracket 32 ​​is mounted on the outside of the sliding plate 16, and an electric cylinder 33 is mounted on the L-shaped bracket 32. The output end of the electric cylinder 33 is connected to the outer wall of the mounting plate 18. The extension and retraction of the electric cylinder 33 adjusts the distance between the two mounting plates 18 to accommodate bags of different widths.

[0086] In summary, this automatic feed feeding device, during use, firstly, since the amount of bagged feed used is basically the same, the travel time of the sliding plate 16 on the track 5 is also basically fixed. The opening and closing time of the drive motor 17 can be encoded by the time controller. A position sensor 27 is also installed on the outside of the mounting plate 18 near the feeding rack. This position sensor 27 is flush with the contact surface between the two transmission belts 19 and is signal-connected to the drive motor 23. When the drive motor 17 rotates, moving the sliding plate 16 to the position of the feeding rack, the position sensor 27 on the mounting plate 18 detects the feed. When the bagged feed is removed, its transmission signal is transmitted to the drive motor 23, which then operates, causing the two transmission belts 19 to rotate. As the sliding plate 16 moves, the two transmission belts 19 clamp the bagged feed at its edge through rotation. Once all the bagged feed is clamped (i.e., when the position sensor 27 on the mounting plate 18 no longer detects the bag), the drive motor 23 stops operating. At this time, the drive motor 17 rotates in the opposite direction, moving the bagged feed along the track 5 towards the feeding hopper 3. After some of the bagged feed enters the feeding hopper 3, it begins to contact the blades 25. The blades 25 then... The bottom of the bagged feed is punctured. As it moves, the puncture opening gradually enlarges, and the feed falls into the feeding hopper 3 through the opening. After feeding, the drive motor 17 continues to rotate, and the empty bag is cut in half by contact with the heating wire 30. After cutting, the drive motor 17 stops rotating. A position sensor 27 can be set at the current position of track 5 to identify and control the drive motor 17 to stop. At the same time, the drive motor 23 is controlled to work, moving the cut packaging bag towards the storage box 31. Under the force of the transmission belt 19, the packaging bag is thrown outward and falls into the storage box 31. The material is collected, and then the position sensor 27 on the positioning component controls the hydraulic cylinder 14 to extend outward, raising the feeding rack and lifting the top bagged feed to a position where the bag clamping structure can operate. The above actions are repeated to complete the automatic feeding. During the feeding process, the screw conveyor 4 can be turned on. The signal control of the position sensor 27 is a well-known technology to those skilled in the art. It can be electrically connected and used according to the instruction manual of the purchased position sensor 27. Furthermore, the screw conveyor 4 used in this application is a well-known device. This application has not made any modifications to its internal structure. It can be directly purchased, installed, and used.

[0087] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
