Description

Technical Field

[0001] The invention belongs to the field of factory silkworm breeding, and in particular relates to a soaking unit for silkworm breeding equipment. Background Art

[0002] The traditional breeding method is a family-style small workshop breeding method, which generally uses small bamboo baskets for breeding. This small bamboo basket has a simple structure, is easy to manufacture, can be woven by hand, and has low cost. Small workshop breeding is a fully artificial breeding method. From silkworm eggs to adults to cocoon collection, all are achieved through manual operation. It is time-consuming and labor-intensive, and the breeding efficiency is very low. In addition, due to seasonal conditions, silkworms can only be raised at specific times. The annual output of silkworm cocoons is extremely low, which cannot meet the needs of today's society and has been gradually eliminated by society.

[0003] In order to make up for the shortcomings of traditional workshop-style silkworm farming, large-scale and factory-based silkworm farming technology was born. In order to meet the requirements of large-scale silkworm farming, it is necessary to design special silkworm farming equipment, such as shelves, silkworm frames, cocoon cages, etc., based on the equipment to achieve silkworm breeding, silkworm transfer between different ages, feed delivery and other processes, it can be seen that these equipment plays an important role in factory-based silkworm farming technology.

[0004] After raising silkworms, the utensils will inevitably have residues such as feed and silkworm sand, and their surfaces are full of bacteria. They need to be thoroughly cleaned and disinfected before they can be put into use again. Therefore, in factory-based silkworm farming technology, corresponding cleaning equipment or cleaning lines are often required. Existing cleaning equipment often includes two parts: flushing and soaking. Flushing can wash away the residues in the utensils, and then soaking can disinfect the bacteria on the surface of the utensils. However, the current soaking equipment often requires workers to assist in loading and unloading materials or to control the loading and unloading materials in real time, which is very inconvenient and time-consuming. It not only increases the probability of failure, but also affects the efficiency of soaking. Failure to load and unload materials in time and human operating errors will affect the cleaning efficiency. Summary of the invention

The shelves 7 in the present invention are stacked in groups to perform the loading-soaking-unloading process.

[0048] The loading table 1 includes a loading conveyor 11, which is a chain conveyor. Two of them are provided for receiving the shelves 7 to be soaked in sequence. After the shelves 7 are loaded into the soaking tank 2, there will be shelves 7 fed in to fill the position. In this way, the shelves 7 are provided to the robot arm 4 in a reciprocating manner, and then the robot arm 4 delivers them into the soaking tank 2.

[0049] The unloading platform 3 includes a unloading conveyor 31, which is a chain conveyor. Two of them are provided for sequentially receiving the soaked shelves 7 and delivering the soaked shelves 7 in sequence. Whenever the shelf 7 is soaked, it is delivered to the unloading conveyor 31 by the robot arm 4, and the soaked shelf 7 is delivered forward, so that the unloading conveyor 31 is idle, and the soaked shelf 7 is delivered in this way repeatedly.

[0050] The soaking tank 2 is welded with 4 sections of tank body 22.

In addition, the second walking bracket 4545 is also connected to the outside with a second guide roller 4546, which not only plays a guiding role, but also improves the walking stability.

[0056] The first walking component 453 and the second walking component 454 cooperate with each other to walk and move laterally on the corresponding walking tracks with synchronous walking movements, thereby driving the entire robot arm 4 to walk and move laterally. The walking mechanism 45 has a simple structure and strong practicality. By setting two groups of walking components, the walking stability of the robot arm 4 can be enhanced.

[0057] The grabbing mechanism 43 is installed on the lifting frame 425, and includes two groups of clamping components that match each other, namely, a first clamping component 431 on the left and a second clamping component 432 on the right. The two groups of clamping components are arranged opposite to each other, and the shelf 7 is clamped or lowered by coordinated action. The first clamping component 431 includes a first clamping cylinder 4311 and a first clamping plate 4314.
