Description

Technical Field

[0001] This utility model relates to the field of silkworm rearing equipment technology, specifically to a silkworm artificial feed feeding and stacking device. Background Technology

[0002] Currently, silkworms are generally fed a combination of natural mulberry leaves and artificial feed. Natural mulberry leaves require manual harvesting, washing, and drying before feeding, which, while low in cost, is relatively cumbersome and heavily influenced by weather, hindering large-scale farming. Artificial feed, on the other hand, is pre-prepared using various ingredients, making it unaffected by weather and suitable for large-scale farming, but at a relatively higher cost.

[0003] With the development of the aquaculture industry, silkworm farming has gradually abandoned the traditional, labor-intensive, family-style farming methods and shifted towards semi-automated or automated farming models. In these semi-automated or automated models, silkworm trays are typically used for rearing to facilitate management and handling. Currently, automatic feeding is largely achieved in these models, as illustrated by patent CN111567487A – a silkworm artificial feed feeding device. In the actual farming process, workers first use a transport device to move the silkworm trays from the silkworm house, then use a stacking device to place the trays one by one onto the feeding line. The feeding line then feeds each tray individually. Finally, the stacking device places the fed trays onto another transport device, which then returns them to the silkworm house for management.

[0004] Currently, automated loading, unloading, and palletizing equipment for silkworm rearing trays generally uses robotic arms. However, the overall cost of robotic arms is relatively high, hindering large-scale application. Furthermore, the weight that robotic arms can grasp is limited, making them unsuitable for handling existing silkworm rearing tray handling and palletizing equipment. To address this issue, patent CN219216789U discloses a grouping device and palletizing system. This palletizing system utilizes a grouping device to improve the neatness of the goods arrangement, ensuring grouping effectiveness and thus increasing the palletizing efficiency. However, this system has a relatively complex structure and high manufacturing cost, hindering large-scale promotion and use. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0025] Reference Figures 1 to 3The illustrated silkworm artificial feed feeding and stacking device includes a frame 10, a conveying mechanism 20, a lifting mechanism 30, and a clamping mechanism 40. The conveying mechanism 20 is mounted on the frame 10. The lifting mechanism 30 is mounted on the frame 10 in the area above the conveying mechanism 20. The clamping mechanism 40 is mounted on the lifting mechanism 30 and is provided with a pair of clamping arms 41 that can open and close in opposite directions. The two clamping arms 41 can cooperate with each other to clamp the material conveyed on the conveying mechanism 20.

[0026] The conveying mechanism 20 can be a traditional belt conveyor or chain conveyor, primarily to adapt to the loading and unloading of existing feeding lines. The lifting mechanism 30 in this application could employ a traditional lifting cylinder, chain drive, or screw drive. However, due to the large weight required for handling the silkworm tray itself, the silkworms attached to it, and any residual feed, the cost of using a lifting cylinder is relatively high, and the requirements for the lifting cylinder are stringent. Therefore, in this application, the lifting mechanism 30 preferably uses a chain drive or screw drive. Furthermore, the clamping mechanism 40 in this application is mainly for driving the two clamping arms 41 to open and close in opposite directions. To control the clamping force, pressure sensors are installed on the opposing sides of both clamping arms 41.

[0027] Furthermore, in one embodiment of this application, for ease of transport, the conveying mechanism 20 includes a rotating shaft 21, a belt 22, and a rotating motor 23. At least two rotating shafts 21 are rotatably mounted on the frame 10. The belts 22 are wound around the rotating shafts 21. The rotating motor 23 is mounted on the frame 10 and connected to one end of any of the rotating shafts 21. Two belts 22 are provided, respectively positioned on both sides of the rotating shaft 21. The silkworm tray rests on both sides of the two belts 22. This arrangement is primarily intended to reduce operating costs.

[0028] See Figures 1 to 3 In one embodiment of this application, in order to achieve heavy lifting, the lifting mechanism 30 includes a lifting frame 31, a rotating shaft 32, and a drive motor 33 for driving the rotating shaft 32 to rotate. The drive motor 33 is mounted on the frame 10. The lifting frame 31 is slidably mounted on the frame 10 and located directly above the conveying mechanism 20. The rotating shaft 32 is rotatably mounted on the frame 10. Both ends of the rotating shaft 32 are provided with first sprockets 34. The first sprockets 34 rotate synchronously with the rotating shaft 32. One end of a chain 35 is wound around each first sprocket 34. The other end of the chain 35 passes around the second sprocket 36 at the corresponding end of the lifting frame 31 and is connected to the frame 10.

[0029] In the above embodiments, the height of the end of the chain 35 connected to the frame 10 is determined according to the required lifting height of the lifting frame 31. Furthermore, using the chain 35 for drive upgrades creates a pulley-like structure, which can reduce the driving force of the drive motor 33 to some extent, thus lowering the requirements on the drive motor 33.

[0030] In order to facilitate the lifting and lowering of the lifting frame 31 and avoid swaying during the lifting and lowering process, in the above-mentioned improved embodiment, slide rods 11 are provided on both sides of the frame 10, and the two ends of the lifting frame 31 are respectively slidably mounted on the slide rods 11 at the corresponding ends by linear bearings.

[0031] Furthermore, in one embodiment, in order to facilitate lifting and ensure uniform force distribution during the lifting process, the rotating shaft 32 is located directly above the lifting frame 31, and the rotation center of the rotating shaft 32 and the rotation center of the second sprocket 36 are located on the same vertical plane.

[0032] Furthermore, to facilitate installation and adapt to different installation spaces, the output end of the drive motor 33 is also connected to the third sprocket 37 on the rotating shaft 32 via a chain 35. Compared to the traditional method where the output end of the drive motor 33 is directly connected to the rotating shaft 32, this structurally reduces the width of the frame 10.

[0033] Furthermore, in order to facilitate the installation of the drive motor 33, an adjustment mounting plate 12 is provided on the frame 10, and the drive motor 33 is mounted on the adjustment mounting plate 12.

[0034] See further Figures 1 to 3 To facilitate clamping the silkworm tray while maintaining a compact structure, the clamping mechanism 40 includes a sliding rod 42, a double-ended lead screw 43, and a servo motor 44. The two ends of the sliding rod 42 are respectively mounted on the lifting frame 31. The servo motor 44 is mounted on the lifting frame 31 and connected to one end of the double-ended lead screw 43. The double-ended lead screw 43 is rotatably mounted on the lifting frame 31. Both clamping arms 41 are slidably mounted on the sliding rod 42. The same end of both clamping arms 41 is respectively connected to the two threaded sections of the double-ended lead screw 43 through lead screw nuts. The two threaded sections on the double-ended lead screw 43 have opposite directions of rotation.

[0035] In the above embodiment, the combination of servo motor 44 and double-ended lead screw 43 can be replaced by a combination of two single-ended lead screws and two servo motors 44, with each servo motor 44 driving a clamping arm 41 to slide on the sliding rod 42 via a single-ended lead screw.

[0036] Furthermore, to improve the load-bearing capacity of the two clamping arms 41 and ensure their stability when clamping the silkworm tray, reinforcing ribs 45 are provided on the two clamping arms 41. A sliding end 46 is provided on one end of the reinforcing rib 45 near the double-ended lead screw 43, and the sliding end 46 can be slidably mounted on the lifting frame 31. In some embodiments, the lifting frame 31 is also provided with a sliding rod 42 parallel to the sliding rod 42, using the two sliding rods 42 to improve the load-bearing capacity of the two clamping arms 41.

[0037] This artificial feed stacking device for silkworms utilizes a conveyor mechanism 20 to receive or transport silkworm trays. A lifting mechanism 30 can drive a clamping mechanism 40 to move up and down, allowing for convenient loading and unloading of silkworm trays from the conveyor mechanism 20. It is also compatible with existing feeding lines. Furthermore, the clamping mechanism 40 is equipped with a pair of opposing clamping arms 41, which clamp the sides of the silkworm tray to accommodate trays of different sizes. The design of the clamping arms 41 also allows for some adaptation to the structure of the silkworm tray, effectively ensuring the stability of the clamp and preventing tipping. This stacking device has a simple structure and is compatible with existing feeding lines and silkworm tray clamping operations.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
