Description

Technical Field

[0001] This utility model relates to the field of silkworm breeding technology, specifically to a miniaturized artificial feed dispenser for silkworms. Background Technology

[0002] During the silkworm's growth process, the feed requirements vary significantly at different stages, and the amount of feed given per feeding must be kept uniform within the same stage. Otherwise, it can easily lead to uneven development of silkworms, an increased rate of unfinished silkworms, and feed waste. Currently, in small-scale settings such as laboratory small-batch rearing and home silkworm rearing, manual operation or the use of simple tools such as small spoons and scrapers for rough quantitative dispensing is often relied upon. Not only is it difficult to accurately control the amount of feed, but it is also inconvenient to adjust the amount of feed for different stages. The few existing quantitative feeding devices mostly adopt a fixed volume chamber design, which requires disassembly and replacement of parts or complex adjustments. They cannot quickly and flexibly adapt to the differentiated feeding requirements of silkworms from early to late stages, resulting in cumbersome operation and low efficiency. On the other hand, some devices such as electrically controlled quantitative valves with adjustment functions are large in size due to the need for power components or complex transmission structures, making them unsuitable for the confined spaces of home silkworm rearing, and they are also costly. Therefore, there is an urgent need for a miniaturized artificial feed dispensing device for silkworms. Utility Model Content

[0003] The purpose of this invention is to address the deficiencies and shortcomings of existing technologies by providing a reasonably designed miniaturized artificial feed dispenser for silkworms, thereby solving the aforementioned problems.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] like Figures 1-5 As shown, this specific embodiment adopts the following technical solution: It includes a feeding cylinder 1, a cylinder cover 2, and a buckle 3. The cylinder cover 2 is hinged to the upper part of the feeding cylinder 1. The cylinder cover 2 is provided with a buckle 3 connected to the feeding cylinder 1. An observation window 14 is provided on the front side of the feeding cylinder 1. The observation window 14 is provided with scale lines 15. Through the transparent observation window 14, the user can directly observe the remaining amount of feed in the feeding cylinder 1, which is convenient for timely addition of feed. Combined with the scale lines 15, it can further realize the quantitative management of the remaining feed, which helps the user to make accurate feeding plans and records, and improves the scientificity and convenience of feeding management. It also includes: The discharge cover 4 is screwed to the bottom of the feeding cylinder 1. The screw connection between the discharge cover 4 and the feeding cylinder 1 makes it easy to install and remove the discharge cover 4, and facilitates thorough cleaning and maintenance of the discharge cover 4 and the inside of the feeding cylinder 1. The discharge cover 4 is provided with a sealing ring 13 that abuts against the feeding cylinder 1. The sealing ring 13 can effectively prevent feed from leaking from the connection gap, ensuring cleanliness and hygiene during the feeding process. The discharge cover 4 has several discharge holes 5. A piston 6 is movably abutted inside the feeding cylinder 1. Push rod 7 is fixedly mounted on the upper part of piston 6 and movably passes through cylinder cover 2. Cylinder cover 2 is provided with vent hole 8. Push handle 9 is fixedly mounted on the upper end of push rod 7. Rubber pad 16 is fixedly mounted on feeding cylinder 1 and anti-slip texture 17 is provided on rubber pad 16. Rubber pad 16 increases the friction between human hand and feeding cylinder 1, provides a stable grip, and effectively prevents operation errors or equipment drops caused by hand slippage during push rod 7, thereby improving the safety and comfort of operation. The fixed cylinder 10 is fixedly installed on the upper part of the cylinder cover 2 and is movably sleeved on the push rod 7. The push rod 7 has positioning grooves 11 on both the left and right side walls. The distance between adjacent positioning grooves 11 on the right side is greater than the distance between adjacent positioning grooves 11 on the left side. The fixed cylinder 10 is provided with a quantitative limiting mechanism 12 that cooperates with the positioning grooves 11. A rotating rod 18 is rotatably mounted in a cylindrical groove at the bottom of the discharge cover 4 via a bearing. A cutting blade 19 is fixedly mounted at the lower end of the rotating rod 18 and is movably mounted against the bottom of the discharge cover 4. A torsion spring 20 connected to the cutting blade 19 is fixedly mounted in the cylindrical groove. A rotating ring 21 connected to the cutting blade 19 is rotatably mounted on the discharge cover 4. By rotating the rotating ring 21, the cutting blade 19 can be driven to quickly cut the feed squeezed out from the discharge hole 5, which can cleanly and neatly stop feeding. This completely solves the problem of sticky feed causing tailing and dripping at the discharge port and contaminating the silkworm bed, ensuring the cleanliness of the silkworm bed after feeding, and is easy and efficient to operate. The quantitative limiting mechanism 12 includes: Fixed block 12-1, there are two fixed blocks 12-1, which are respectively fixedly installed on the left and right sides of the fixed cylinder 10. A positioning block 12-2 is movably inserted into the fixed block 12-1. The positioning block 12-2 passes through the opening on the side wall of the fixed cylinder 10 and is matched with the positioning groove 11. Spring 12-3, there are two springs 12-3, which are respectively fixedly installed in two fixed blocks 12-1, and one end of spring 12-3 is fixedly connected to positioning block 12-2. A control rod 12-4 is movably inserted on the fixed block 12-1, and one end of the control rod 12-4 is rotatably connected to the fixed block 12-1 through a bearing. Rotating handle 12-5, there are two rotating handles 12-5, which are respectively fixedly installed at the other end of two control rods 12-4. The control rods 12-4 are provided with spiral patterns 12-6. The fixed block 12-1 is provided with spiral grooves 12-7 that cooperate with the spiral patterns 12-6. The quantitative limiting mechanism 12 can actively control the positioning block 12-2 on one side to retract and lock into the fixed block 12-1 through the cooperation of the spiral patterns 12-6 and the spiral grooves 12-7, so that it is completely disengaged from the push rod 7, or release the positioning block 12-2 so that it is engaged in the positioning groove 11 under the push of the spring 12-3. The working position of the equipment can be clearly switched.

[0019] When using this invention, after opening the cylinder cover 2 and loading the artificial feed into the feeding cylinder 1, close the cylinder cover 2 and fasten the buckle 3. At this time, the piston 6 is located inside the cylinder cover 2. When feeding, first select the working position according to the feeding amount required for the silkworm's age through the quantitative limiting mechanism 12. If a small feeding amount is required, pull the right rotating handle 12-5 to the right, so that the right control lever 12-4 drives the right positioning block 12-2 to disengage from the positioning groove 11. Then rotate the right rotating handle 12-5 so that the right spiral 12-6 screws into the matching spiral groove 12-7, realizing the retraction and locking of the right positioning block 12-2, while ensuring the left positioning. Under the action of spring 12-3, block 12-2 is engaged in the positioning groove 11 on the left side of push rod 7. If a large feeding volume is required, the opposite operation is performed. During operation, the user grips the feeding cylinder 1 and presses down the push handle 9 to drive the piston 6 forward. The feed is evenly squeezed out from multiple discharge holes 5 of the discharge cover 4. During this process, the positioning block 12-2 on the activated side will slide out in sequence and be engaged in the adjacent positioning groove 11 on the corresponding side of push rod 7. By selecting to engage the positioning block 12-2 on the left or right side in the positioning groove 11, the single push stroke determined by the fixed spacing of the positioning groove 11 on that side is selected, thereby realizing precise control and rapid switching of the extruded feed volume.

[0020] Compared with the prior art, the beneficial effects of this utility model are: By using the positioning grooves 11 with different spacings on both sides of the push rod 7 in conjunction with the switchable quantitative limiting mechanism 12, users can quickly select between large and small feeding levels. This structure ensures that the single push stroke remains constant, thereby achieving precise control over the extruded feed volume, effectively meeting the differentiated feed requirements of silkworms from early to late stages, and ensuring uniformity of development. By rotating the rotating ring 21 to drive the cutting blade 19, the viscous feed squeezed out from the discharge hole 5 can be cut quickly and cleanly, which completely solves the problem of feed trailing and dripping after feeding and contaminating the silkworm seat. The quantitative limiting mechanism 12 uses the spiral pattern 12-6 for transmission, which can actively retract and lock the positioning block 12-2 on one side, clearly defining the working position of the equipment; Through the transparent observation window 14, users can directly observe the remaining amount of feed in the feeding hopper 1, which facilitates timely addition of feed. Combined with the scale line 15, it can further realize the quantitative management of the remaining feed, which helps users to make precise feeding plans and records, and improves the scientificity and convenience of feeding management.

[0021] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
