Description

Background Technology

[0001] This utility model relates to the field of silkworm breeding technology, and in particular to an automatic silkworm feeding system. Technical Field

[0002] Silkworm production offers economic, social, and ecological benefits, making it a wealth-generating industry that aligns with the national policies of resource conservation and environmental protection. It plays a vital role in boosting foreign trade, agricultural efficiency, farmers' income, and the ecological environment of silkworm farming areas. Achieving intelligent and efficient silkworm farming is of great significance for improving the overall benefits of silkworm production in my country and promoting its sustainable development.

[0003] Silkworm farming uses more than just mulberry leaves as feed; silkworm feed includes other substances. Young silkworms need to be fed wet feed, which is made by mixing powdered feed with water to form a cake-like consistency, then steaming and shaping it, and finally cutting it into pieces. Currently, the wet feed is usually sliced ​​manually before being fed. This manual method is inefficient, labor-intensive, and produces uneven slices of varying thickness and length, making it difficult to ensure consistent feed distribution. This hinders the silkworms' even feeding and negatively impacts their growth and development. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an automatic silkworm feeding system that can automatically feed silkworms and distribute the feed evenly.

[0005] To achieve this objective, the technical solution adopted by this utility model is as follows:

The pusher cylinder is a tubular structure with openings at both ends. One end of the pusher cylinder is connected to the hopper, and the other end is connected to the extrusion cylinder. A spiral pusher rod is rotatably installed inside the pusher cylinder. One end of the spiral pusher rod passes through the pusher cylinder and the hopper in sequence and is driven by a pusher motor.

[0007] The end of the extrusion cylinder away from the pusher cylinder is provided with a cover plate, the cover plate is provided with a discharge port, the discharge port is provided with a discharge plate, the discharge plate is provided with a through discharge hole, and the discharge hole is provided with several evenly spaced discharge holes.

[0008] A connecting plate is fixedly installed on one side of the hopper, and the reciprocating table is connected to the connecting plate to drive the connecting plate to move back and forth.

[0009] Furthermore, the reciprocating table includes a translation table, a sliding frame, and a threaded rod. One side of the translation table is fixedly connected to the connecting plate, and the translation table is slidably disposed within the sliding frame. The threaded rod is threaded through the translation table, and both ends of the threaded rod are rotatably connected to the sliding frame. The threaded rod is driven by a reciprocating motor.

[0010] Furthermore, the sliding frame includes a fixed plate and a sliding rod. Two fixed plates are arranged opposite each other, and two sliding rods are provided. The two sliding rods are respectively located on both sides between the two fixed plates, and the two ends of the sliding rods are respectively fixedly connected to the two fixed plates. The threaded rod is located between the two sliding rods, and the two ends of the threaded rod are respectively rotatably connected to the two fixed plates.

[0011] The translation stage is slidably sleeved on the two sliding rods, the reciprocating motor is fixedly connected to one of the fixed plates, and the output shaft of the reciprocating motor is drivenly connected to the threaded rod.

[0012] Furthermore, a first pulley is fixedly installed at one end of the spiral pusher rod located outside the hopper, the pusher motor is fixedly installed on the fixed plate, and the output shaft of the pusher motor is provided with a second pulley, the second pulley being connected to the first pulley via a transmission belt.

[0013] Furthermore, a cutting mechanism is provided at the end of the extrusion cylinder away from the pusher cylinder. The cutting mechanism includes a fixed frame, a cutting frame and an electric push rod. A frame opening is provided on one side of the fixed frame. The fixed frame is embedded in the end of the extrusion cylinder away from the pusher cylinder through the frame opening, and the fixed frame is fixedly connected to the outer wall of the extrusion cylinder.

[0014] The cutting frame is located on the side of the discharge port away from the frame opening, and both ends of the cutting frame are slidably connected to the fixed frame. The cutting frame is fixedly equipped with a cutting blade, and the cutting blade faces the frame opening.

[0015] The electric push rod is located on the side of the discharge port away from the frame opening, and both ends of the electric push rod are fixedly connected to the cutting frame and the fixed frame, respectively.

[0016] Furthermore, the cutting blade is made of steel wire.

[0017] Furthermore, the extrusion cylinder has a funnel-shaped structure, and the wide end of the extrusion cylinder is electrically connected to the pusher cylinder, while the narrow end of the extrusion cylinder is the discharge port.

[0018] Furthermore, a hopper opening is provided on the top side of the hopper away from the connecting plate, and a hopper cover is rotatably provided on the hopper opening.

[0019] The beneficial effects of this utility model are:

[0020] 1. Wet feed is placed into the feed hopper. Under the action of the screw pusher, the feed is discharged through the outlet. Because the discharge plate has through-holes, the feed is compressed into multiple strip-shaped structures and discharged evenly through the outlets, ensuring uniform and consistent feed distribution. By setting up the reciprocating table on the silkworm rearing rows, the extrusion cylinder can be driven to move evenly on the rows, thereby achieving uniform feed distribution, which is beneficial for the silkworms to feed evenly and ensures their normal growth and development.

[0021] 2. Driven by a reciprocating motor, the threaded rod rotates, allowing the translation stage to move along the sliding rod. By controlling the forward and reverse rotation of the reciprocating motor, the translation stage can move back and forth on the sliding frame, thereby evenly distributing several feeds into the silkworm rearing area.

[0022] 3. When the reciprocating table moves to the preset distance, the strip-shaped feed is discharged to the corresponding length. The electric push rod extends, and the cutting blade moves toward the discharge hole, so that the cutting blade cuts the strip-shaped feed, allowing the silkworm rearing row to be fed the required feed.

[0032] Please also see Figures 1 to 5 The automatic silkworm feeding system of this utility model, according to a preferred embodiment, includes a pusher cylinder 1, a feed bin 2, an extrusion cylinder 3, and a reciprocating table 4.

[0033] The pusher cylinder 1 is a tubular structure open at both ends. One end of the pusher cylinder 1 is connected to the hopper 2, and the other end is connected to the extrusion cylinder 3. A spiral pusher rod 11 is rotatably installed inside the pusher cylinder 1. One end of the spiral pusher rod 11 passes through the pusher cylinder 1 and the hopper 2 in sequence and is driven by the pusher motor 12. Figure 2 As shown, bearings are provided at both ends of the spiral push rod 11. The inner ring of the bearing is fixedly connected to the spiral push rod 11, and a support frame is provided on the outer ring of the bearing. The support frame is fixedly connected to the inner wall of the push cylinder 1.

[0034] A cover plate 31 is provided at the end of the extrusion cylinder 3 away from the pusher cylinder 1. A discharge port 311 is provided through the cover plate 31, and a discharge plate 32 is provided at the discharge port. The discharge plate 32 has several through discharge holes 321, which are evenly spaced. In this embodiment, five discharge holes 321 are provided. Figure 3As shown, the extrusion cylinder 3 has a funnel-shaped structure, and the wide end of the extrusion cylinder 3 is electrically connected to the pusher cylinder 1, while the narrow end of the extrusion cylinder 3 is the discharge port 311. The funnel-shaped structure of the extrusion cylinder 3 facilitates the extrusion of feed.

[0035] A connecting plate 21 is fixedly installed on one side of the hopper 2. The reciprocating table 4 is connected to the connecting plate 21 to drive the connecting plate 21 to move back and forth.

[0036] Wet feed is placed into the feed hopper 2. Under the action of the screw pusher 11, the feed is discharged through the discharge port 311. Because the discharge plate 32 is provided with a through discharge hole 321, the feed is pressed into multiple strip-shaped structures and discharged evenly through the discharge hole 321, ensuring the uniformity and consistency of feed distribution. By setting up the reciprocating table 4 on the silkworm rearing row, the extrusion cylinder 3 can be driven to move evenly on the silkworm rearing row, thereby achieving even feed distribution, which is conducive to the uniform feeding of silkworms and ensures that silkworms can grow and develop normally.

[0037] like Figure 4 As shown, the reciprocating table 4 includes a translation table 41, a sliding frame 42, and a threaded rod 43. One side of the translation table 41 is fixedly connected to the connecting plate 21, and the translation table 41 is slidably disposed in the sliding frame 42. The threaded rod 43 is threaded through the translation table 41, and both ends of the threaded rod 43 are rotatably connected to the sliding frame 42. The threaded rod 43 is driven by a reciprocating motor 44.

[0038] The sliding frame 42 includes a fixed plate 421 and a sliding rod 422. Two fixed plates 421 are arranged opposite each other, and two sliding rods 422 are arranged. The two sliding rods 422 are located on both sides between the two fixed plates 421, and the two ends of the sliding rods 422 are fixedly connected to the two fixed plates 421 respectively. A threaded rod 43 is located between the two sliding rods 422, and the two ends of the threaded rod 43 are rotatably connected to the two fixed plates 421 respectively.

[0039] The translation stage 41 is slidably sleeved on the outside of the two sliding rods 422. The reciprocating motor 44 is fixedly connected to one of the fixed plates 421, and the output shaft of the reciprocating motor 44 is connected to the threaded rod 43 for transmission.

[0040] In this embodiment, the fixing plate 421 is fixedly mounted above the silkworm rearing row. Driven by the reciprocating motor 44, the threaded rod 43 rotates, allowing the translation platform 41 to move along the sliding rod 422. By controlling the forward and reverse rotation of the reciprocating motor 44, the translation platform 41 can move back and forth on the sliding frame 42, thereby evenly distributing several feeds into the silkworm rearing row.

[0041] like Figure 1 and Figure 4As shown, a first pulley 111 is fixedly installed at one end of the spiral pusher rod 11 outside the hopper 2. The pusher motor 12 is fixedly mounted on the fixed plate 421 via a motor frame, and a second pulley 121 is installed on the output shaft of the pusher motor 12. The second pulley 121 is connected to the first pulley 111 via a transmission belt 122. Driven by the pusher motor 12, the second pulley 121 drives the first pulley 111 to rotate via the transmission belt 122, thereby realizing the rotation of the spiral pusher rod 11.

[0042] like Figure 2 and Figure 5 As shown, a cutting mechanism is provided at the end of the extrusion cylinder 3 away from the push cylinder 1. The cutting mechanism includes a fixed frame 5, a cutting frame 51 and an electric push rod 52. A frame opening 501 is provided on one side of the fixed frame 5. The fixed frame 5 is embedded in the end of the extrusion cylinder 3 away from the push cylinder 1 through the frame opening 501, and the fixed frame 5 is fixedly connected to the outer wall of the extrusion cylinder 3.

[0043] The cutting frame 51 is located on the side of the discharge port 311 away from the frame opening 501, and both ends of the cutting frame 51 are slidably connected to the fixed frame 5. The cutting frame 51 is fixedly equipped with a cutting blade 511, and the cutting blade 511 faces the frame opening 501. In this embodiment, the cutting blade 511 is a steel wire, which is a high-hardness steel wire with a size of 0.1mm.

[0044] The electric push rod 52 is located on the side of the discharge port 311 away from the frame port 501, and both ends of the electric push rod 52 are fixedly connected to the cutting frame 51 and the fixed frame 5, respectively.

[0045] When the reciprocating table 4 moves to the preset distance, the strip-shaped feed is discharged to the corresponding length. The electric push rod 52 extends, and the cutting blade 511 moves toward the discharge hole 321, so that the cutting blade 511 cuts the strip-shaped feed, allowing the required feed to be fed into the silkworm rearing row. After the feed is cut, the electric push rod 52 retracts and returns to its original position.

[0046] Preferably, the top of the hopper 2 is provided with an opening on the side away from the connecting plate 21, and the opening is rotatably fitted with a hopper cover 22. By opening the hopper cover 22, feed can be placed into the hopper 2.

[0047] The automatic silkworm feeding system of this embodiment can be configured with an appropriate number of feeders based on the width of the silkworm rearing rows, and its operation can be controlled by a PLC controller. The operation process of this embodiment is as follows:

[0048] Wet feed is placed into the feed hopper 2. Under the action of the screw pusher 11, the feed is discharged through the discharge port 311. Since the discharge plate 32 is provided with a through discharge hole 321, the feed is pressed into multiple strip-shaped structures and discharged evenly through the discharge hole 321.

[0049] At the same time, the reciprocating motor 44 drives the threaded rod 43 to rotate in the forward direction, and the translation table 41 moves along the sliding rod 422, so that the extrusion cylinder 3 moves along the length of the silkworm rearing row, and the feed is evenly distributed into the silkworm rearing row.

[0050] When the reciprocating table 4 moves to the preset distance, the strip-shaped feed is discharged to the corresponding length. The PLC controller controls the pusher motor 12 to stop according to the signal of the reciprocating motor 44, and at the same time controls the electric push rod 52 to extend. The cutting blade 511 moves toward the discharge hole 321, so that the cutting blade 511 cuts the strip-shaped feed. After the feed is cut, the electric push rod 52 shortens and resets.

[0051] The PLC controller controls the reciprocating motor 44 to reverse according to the reset signal of the electric push rod 52, so that the translation stage 41 moves to the initial position.
