Description
Technical Field
[0001] The invention relates to the technical field of silkworm breeding, and in particular to a mulberry feeding machine for automated silkworm breeding. Background Art
[0002] Silkworm breeding is an agricultural activity with a long history. It involves the breeding process of silkworm, a domesticated silk-producing insect of the class Insecta, order Lepidoptera, family Bombyx, and genus Bombyx. The silkworm goes through four developmental stages: egg, larva (silkworm), pupa, and moth (adult). The larvae need to molt four times, gradually grow up and eat a lot of mulberry leaves, and finally spin cocoons on the cocoon. During the breeding process, it is necessary to provide a suitable silkworm room environment, including hardened floors and walls for disinfection and cleaning, while maintaining appropriate temperature and humidity in the silkworm room. In addition, it is necessary to prepare sufficient mulberry leaves as feed, and pay attention to the prevention and control of diseases and pests to ensure the healthy growth of silkworms and the high quality of cocoons. Silkworm breeding not only has important economic value, but is also an important part of Chinese traditional culture.
[0003] Mulberry leaves need to be provided during the silkworm breeding process, especially in automated silkworm breeding. Mulberry leaves are crushed, conveyed and fed for silkworms to eat. In the transportation stage, the mulberry leaves are often conveyed from the crushing stage to the feeding stage by a mulberry feeder. However, some existing mulberry feeders have fixed structures and are located at a high position. When they fail or need to be cleaned, workers can only climb to a height with a ladder for processing. This is not only dangerous, but can only process a small range at a time, resulting in the need to constantly move the ladder and climb up and down, which is time-consuming and labor-intensive. For this reason, we propose a mulberry feeder for automated silkworm breeding. Summary of the invention

[0044] Working principle: The mulberry feeder is set between the mulberry leaf crusher and the mulberry leaf feeder. In the initial state, the lifting plate 2 is located at a low position, and each L-shaped safety plate 91 is in an open state. First, according to the height difference between the crusher and the feeder, one hand holds the first handle 79 and pulls it up to drive the tooth plate 74 to lift up. At this time, the two sets of movable rings 75 on the tooth plate 74 will slide on each fixed rod 76 and compress each spring 78 until the tooth plate 74 no longer blocks the corresponding U-shaped sleeve 73. The second handle 711 is held by hand to drive the U-shaped rotating plate 710 to slide up between the two sets of U-shaped clamping sleeves 73 and press against the rectangular frame 4 to tilt it to a certain angle. The two sets of U-shaped clamping sleeves 73 also slide to the corresponding positions in each slide groove 72. Then, the first handle 79 is released. Under the rebound effect of the two sets of springs 78, the tooth plate 74 is reset and clamps the U-shaped clamping sleeve 73 at the corresponding position, thereby fixing the U-shaped rotating plate 710, so that the rectangular frame 4 is tilted and fixed. Then, Then, according to the height of the feeder and the crusher, the handle 63 is rotated first, and the rotating sleeve 64 is driven to rotate through the spiral bevel gear commutator 62. The rotating sleeve 64 drives the transmission screw 65 to move up and down, and then drives the lifting plate 2 to move up and down until one side of the rectangular frame 4 is aligned with the top of the feeder and the other side is located below the crusher. Then, each L-shaped insurance plate 91 is rotated, and each magnet 94 is tightly attached to and adsorbed on each limit plate 3. During operation, the servo motor 82 is controlled to start, and the two sets of transmission rollers 81 are driven to rotate synchronously through the conveyor belt 83, which drives the conveyor belt 83 to operate. After being crushed by the crusher, the mulberry leaves fall onto the conveyor belt 83 and are transported to the feeder for loading through the conveyor belt 83. When the lifting mechanism 6 fails to support the lifting plate 2 and falls, each L-shaped insurance plate 91 can jam the lifting plate 2. When it is necessary to repair or clean the structure on the lifting plate 2, each L-shaped insurance plate 91 is opened again, and then it is lowered by the lifting mechanism 6.
[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
