Description

Technical Field

[0001] This application relates to a feeding device, and more particularly to a feed additive feeding device. Background Technology

[0002] Animals are typically fed with feed, but feed alone cannot meet their nutritional needs for growth. Additives are usually added to the feed to improve its nutritional value, enhance animal production performance, and protect animal health. The feed and additives are mixed together before use.

[0003] Chinese Patent Publication No. CN 222664865 U discloses a feeding device for a feed additive, including a support base. The inner wall of the support base has a groove, and two support frames are fixedly connected to the inner wall of the groove. A fixed connection is fixedly connected between the support frames, and a second motor is fixedly connected to the inner wall of the fixed connection. A discharge plate is fixedly connected to the lower output end of the second motor. The surface of the discharge plate has a circular opening, and the inner wall of the fixed connection has a rotating groove. The discharge plate is slidably connected to the inner wall of the rotating groove. A discharge auger is fixedly connected to the inner wall of the discharge plate, and multiple holes are formed on the outer surface of the discharge auger. An outlet is fixedly connected to the upper surface of the feed hopper, and a circular hole is formed on the inner wall of the fixed connection.

[0004] However, the aforementioned patent has the following drawbacks:

[0005] 1. The additives are discharged through the circular opening on the surface of the discharge plate. Although the additives can be discharged in a regular manner, it is limited to a quantitative and constant-speed discharge. When it is necessary to change the discharge volume and discharge speed, it cannot meet the requirements. Furthermore, the additives cannot be discharged continuously, which will lead to a decrease in uniformity when mixed with feed later.

[0006] Second, when additives are administered through the device, it is usually necessary to ensure the dryness and purity of the additives. If the additives are damp, it will affect subsequent administration. Utility Model Content

[0007] The purpose of this invention is to provide a feed additive feeding device that can uniformly add feed additives into a feed additive mixing equipment, control the feed addition speed during the addition process, and pre-dry and filter the additives.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is a feed additive feeding device, including a feeding device and a feeding assembly. The feeding device is connected to the feeding assembly, and the additive is filled in the feeding assembly. The feeding assembly is connected to a drying blower, which transports the additive in the feeding assembly to the feeding device. A control assembly is provided at the bottom of the feeding device, through which the additive can be discharged. The control assembly includes a baffle and a control plate. The baffle is connected to the bottom of the feeding device. The baffle is provided with a plurality of feeding ports arranged in a circular array, with the diameter of the feeding ports arranged from small to large. The control plate is provided with a control port, which aligns with the feeding port when the control plate rotates.

[0009] Furthermore, the control panel is located below the baffle and is connected to the baffle via a shaft. The control panel and the baffle are set parallel to each other and are in close contact. The control panel can rotate via the shaft.

[0010] Furthermore, the size of the control port is consistent with the maximum feed port size on the baffle. By rotating the control plate, the control port is aligned with one of the feed ports on the baffle, and the additive can be discharged from there.

[0011] Furthermore, the feeding device includes an outer shell and a pushing assembly. The outer shell is cylindrical with openings at both ends. A horizontal sealing plate is provided at the top of the outer shell. The pushing assembly is located inside the outer shell and pushes the additive inside the outer shell.

[0012] Furthermore, the feeding assembly includes a rotating rod and a pushing blade. The rotating rod is located inside the housing and coincides with the central axis of the housing. The pushing blade is fixed on the rotating rod and extends spirally along the length of the rotating rod. When the rotating rod rotates, the pushing blade pushes the additive inside the housing, so that the additive is discharged from the lower opening of the housing.

[0013] Furthermore, the feeding assembly includes a feed pipe shell with a feed funnel and a filter screen installed inside the feed funnel. The additive enters the feed pipe shell through the feed funnel, and the filter screen filters the additive.

[0014] Furthermore, the conveying pipe shell is connected to a scraping assembly, which includes a scraping ring located inside the conveying pipe shell. A flat strip opening is provided on the conveying pipe shell. The scraping ring is connected to a connecting rod, which passes through the flat strip opening. The connecting rod is connected to a rotating rod through a transmission assembly. When the rotating rod rotates, it drives the scraping ring to clean the inner wall of the conveying pipe shell.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: the additive is fed into the internal storage space of the feeding component through the feeding funnel, the drying blower is turned on to dry the additive, and then the drive motor is started. The drive motor drives the rotating rod to rotate and at the same time drives the scraping component to make linear reciprocating motion in the feeding component to scrape off the additive attached to the conveying pipe shell. The additive enters the feeding device and is pushed outward by the pushing device. At the same time, the control plate on the rotation control component rotates and the control port on the control plate is adjusted to the appropriate feeding port position to continuously discharge the additive.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. It should be understood that the preferred embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. In the embodiments, the components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application.

[0025] See Figures 1 to 7 As shown, a feed additive feeding device includes a support frame, a feeding device, and a feeding assembly. The support frame includes a support leg 1 and a support plate 2. The support leg 1 is vertically arranged, with its bottom end placed on the ground. The support plate 2 is mounted on the support leg 1. The support plate 2 is horizontal, with a certain vertical gap between it and the ground. An opening is provided on the support plate 2. A feeding device is located above the support frame. The bottom end of the feeding device passes through the opening in the support plate 2 and is open. The feeding assembly is connected to one side of the top of the feeding device, and the feeding assembly has a feed inlet. The additive is first fed into the feeding assembly through the feed inlet, then transferred and conveyed by the feeding assembly to the feeding device, and finally discharged through the opening at the bottom end of the feeding device.

[0026] To distribute the feed more evenly, the aforementioned feeding device includes an outer shell 3 and a pushing assembly. The outer shell 3 is cylindrical with openings at both ends, meaning the inside of the feeding device has storage space. The bottom of the outer shell 3 is connected to a support, and the top of the outer shell 3 is equipped with a horizontal sealing plate. The pushing assembly is located inside the outer shell 3 and includes a rotating rod 4 and a pushing blade 5. The pushing blade 5 is fixed to the rotating rod 4 and extends spirally along the length of the rotating rod 4. The rotating rod 4 is located inside the outer shell 3 and coincides with the central axis of the outer shell 3. When the rotating rod 4 rotates, the pushing blade 5 pushes the additive inside the outer shell 3, causing the additive to be discharged from the lower opening of the outer shell 3.

[0027] When controlling the rotation of the rotating rod 4, it needs to be controlled by the drive motor 6. A through hole is provided at the center of the horizontal sealing plate at the top of the outer shell 3. A rolling bearing is provided in the through hole. One end of the rotating rod 4 passes through the rolling bearing in the through hole and is connected to the drive motor 6. The drive motor 6 is mounted on the support rod 7. The support rod 7 is vertically fixed to the support plate 2. At this time, the drive motor 6 is located above the outer shell 3, and the upper end of the rotating rod 4 is connected to the drive motor 6. When the additive enters the interior of the outer shell 3, the rotation of the rotating rod 4 drives the pusher blade 5 to discharge the additive from the bottom opening of the feeding device.

[0028] To ensure uniform additive discharge and control the discharge rate, a control component is installed at the bottom of the feeding device. This component includes a baffle 8 and a control plate 9. Specifically, the baffle 8, a circular plate, is installed at the bottom opening of the feeding device, covering the opening. Several feeding ports are provided on the baffle 8, arranged around its center line. These ports are of varying sizes and can be arranged in ascending order, with a certain interval between adjacent ports. The control plate 9 is located below the baffle 8 and controls... The control plate 9 is provided with a control port 10. The size of the control port 10 is the same as the maximum feed port size on the baffle 8. The control plate 9 is connected to the baffle 8 through a shaft. The size and shape of the control plate 9 are the same as those of the baffle 8. It is set on the same axis as the baffle 8 and is set parallel to the baffle 8. The control plate 9 and the baffle 8 are in close contact. When the additive is discharged, the control component rotates the control plate 9 to align the control port 10 with one of the feed ports on the baffle 8. At this time, the additive can be discharged through this port. When it is necessary to adjust the discharge speed of the additive, the control plate 9 is rotated to rotate the control port 10 to a suitable feed port position.

[0029] A connection hole is provided on the outer shell 3 of the feeding device, and the connection hole is connected to the feeding component. The feeding component includes a conveying pipe shell 11, which is divided into a front end and a rear end. The front end of the conveying pipe shell 11 is vertically connected to the feeding device. The conveying pipe shell 11 is cylindrical, that is, the inside of the conveying pipe shell 11 has a storage space. A feed inlet is provided on the upper outer wall of the conveying pipe shell 11, and a feed funnel 12 is connected to the feed inlet. The upper opening of the feed funnel 12 is larger than the bottom opening. The bottom end of the feed funnel 12 is connected to the feed inlet of the conveying pipe shell 11. A movable cover plate is provided at the connection between the bottom end of the feed funnel 12 and the feed inlet. The bottom dimension of the feed funnel 12 matches the dimensions of the feed inlet and the movable cover plate. The additive can be put into the conveying pipe shell 11 through the feed funnel 12. After the additive is put into the conveying pipe shell 11, the movable cover plate is closed.

[0030] Additives are usually in powder or granule form. When using additives, they need to be screened to remove impurities mixed in with them. A filter screen is installed in the feed hopper 12. The mesh size of the filter screen is set according to the size of the additive used. That is, the additive can be fed into the feeding device through the filter screen, while impurities such as stones and wood chips mixed in with the additive are filtered and blocked by the filter screen.

[0031] When mixing additives with feed, the additives usually need to be in a dry state. To ensure that the discharged additives are relatively dry, a vertical sealing plate 13 is provided at the rear end of the feed pipe shell 11. The vertical sealing plate 13 seals the port at the rear end of the feed pipe shell 11 and has an air outlet. A drying blower 14 is connected to the outside of the air outlet. The drying blower 14 is equipped with an electric heating wire 15, which generates heat when energized. When the additives are fed into the storage space of the feed pipe shell 11 from the feed hopper 12, the drying blower 14 is turned on. The drying blower 14 blows the heat generated by the electric heating wire 15 into the internal storage space of the feed pipe shell 11 and dries the additives. At the same time, the air force of the drying blower 14 can blow the additives into the feeding device.

[0032] During the process of the additive being blown into the feeding device by the drying blower 14, some additives may fail to enter the feeding device, resulting in some additives adhering to the inner wall of the storage space of the conveying pipe shell 11. In this application, a scraping assembly is connected to the conveying pipe shell 11. The scraping assembly includes a scraping ring 16, which is located inside the conveying pipe shell 11. A flat strip-shaped opening is provided on the conveying pipe shell 11, extending along the length of the conveying pipe shell 11. A connecting rod 17 is connected to the scraping ring 16, which passes through the flat strip-shaped opening. The connecting rod 17 is connected to the rotating rod 4 through the transmission assembly 18. When the rotating rod 4 rotates, it will drive the scraping ring 16 to perform linear reciprocating motion inside the conveying pipe shell 11. At this time, the scraping ring 16 cleans the inner wall of the conveying pipe shell 11.

[0033] The aforementioned transmission assembly 18 includes a rotating wheel 19 and a limiting frame 20. The rotating wheel 19 is disposed above the horizontal sealing plate. The rotating wheel 19 is disc-shaped and is parallel to the horizontal sealing plate. A through hole is provided in the center of the rotating wheel 19. The rotating rod 4 passes through the through hole in the center of the rotating wheel 19 and is fixedly connected to the rotating wheel 19. A protruding rod 21 is provided on the upper surface of the rotating wheel 19. The protruding rod 21 is offset from the center of the rotating wheel 19.

[0034] The limiting frame 20 is abutted against the end of the connecting rod 17. The limiting frame 20 is a rectangular frame and is located above the rotating wheel 19. Both the protruding rod 21 and the rotating rod 4 pass through the area enclosed by the limiting frame 20. A limiting tube 22 is provided at the top of the conveying pipe shell 11, with its central axis parallel to the central axis of the conveying pipe shell 11. The connecting rod 17 passes through the limiting tube 22 and extends towards the drying blower 14. The limiting tube 22 limits the connection rod 17. It should be noted that the limiting frame 20 is a rectangular frame. The width of frame 0 is the length of the feed tube shell 11. The width of the limiting frame 20 is less than the diameter of the rotating wheel 19, and the distance between the protruding rod 21 and the rotating rod 4 is greater than 1 / 2 of the width of the limiting frame 20. That is, let the straight distance between the protruding rod 21 and the rotating rod 4 be a, and the width of the limiting frame 20 be b. Then a > b * 1 / 2. In this way, when the rotating wheel 19 rotates, it will drive the protruding rod 21 to make a circular motion. The protruding rod 21 will contact the limiting frame 20 and apply a pushing force to the limiting frame 20, thereby driving the connecting rod to make a linear reciprocating motion above the feeding assembly.

[0035] The initial position of the scraping ring 16 is set between the feed inlet and the drying blower 14, and the outer wall of the scraping ring 16 is in contact with the inner wall of the feed assembly. When the rotating rod 4 rotates, the rotating wheel 19 and the connecting rod 17 drive the scraping ring 16 to make linear reciprocating motion in the feed assembly to scrape off the additives attached to the inner wall of the feed assembly.

[0036] Because the feed tube shell 11 has a flat strip opening, the additive may splash outward from the flat strip opening during the drying process. This application provides a blocking component on the feed tube shell 11 to block the flat strip opening. The blocking component includes a retractor 23 and a sealing strip 24. The sealing strip 24 is made of a thin steel sheet with high strength and wear resistance, the same material as the strip of a measuring tape. There are two retractors 23, each installed on one of the two short sides of the flat strip opening, i.e., the two retractors 23 are installed opposite each other during the winding process. The retractor 23 has an outlet and a reset roller shaft inside. The width of the seal 24 is greater than or equal to the width of the flat strip opening. One end of the seal 24 is installed on the reset roller shaft and the seal 24 is wound around the reset roller shaft. The free end of the seal 24 extends out from the outlet of the retractor 23. The free end of the seal 24 has a through hole. The size of the through hole is adapted to the outer circumference of the connecting rod 17. The connecting rod 17 passes through the through hole. Similarly, the other end of the seal 24 in the other retractor 23 is also installed on the connecting rod 17. At this time, the two seals 24 seal the flat strip opening.

[0037] To better seal the flat strip opening, slots are provided on the two transverse inner walls of the flat strip opening. The two slots are arranged opposite each other and are horizontally arranged along the transverse inner walls. The length of the slots is the same as the length of the flat strip opening. The long sides of the two sealing strips 24 are located in the slots. When the scraping ring 16 moves towards the feeding device, the retractor 23 near the feeding device retracts the sealing strips 24, and the sealing strips 24 in the retractor 23 near the drying blower 14 are brought out. When the scraping ring 16 moves in the opposite direction, the retractor 23 near the drying blower 14 retracts the sealing strips 24, and the sealing strips 24 in the retractor 23 near the feeding device are brought out. At this time, when the scraping ring 16 makes a linear reciprocating motion in the feeding assembly, the sealing strips 24 keep tightly sealing the flat strip opening.
