Embodiment 1

[0040] like Figure 1-3 As shown, the grabbing device for snails includes a catch box 16 for scooping snails, the catch box 16 is connected to the receiving box 7 through the transmission pipeline 8, and the receiving box 7 is connected to the collection box 1 through the connecting pipe 4, The catch box 16 is provided with a hydrological acquisition device, and the collection box 1 is provided with a capture data acquisition device, and both the hydrological acquisition device and the capture data acquisition device are connected with the computer. During the snail cage fishing process, the fishing box 16 is placed in the snail breeding area to catch the snails, and the snails caught are directly transferred to the suction receiving box 7 through the transmission pipeline 8, so that the snails can be removed from the breeding area. In-house fishing, and finally the collection box 1 collects the capture data of the captured snails. During the whole process, there will be no pr...

Embodiment 2

[0051] refer to Figure 4 , the computer operation process of the grabbing device for snails:

[0052] S1: Input the hydrological parameters of the fishing area into the computer;

[0053] S2: input the snail parameters of fishing into the computer;

[0054] S3: According to the hydrological parameters and snail parameters, the regional catch model is obtained to calculate the regional catch;

[0055] The area catch model used is as follows:

[0056] Minθ,λθ;

[0057] s°t°-y i +Yλ≥0;

[0058]

[0059] λ≥0;

[0060] In the formula, it is a constant vector of N×1, which is the input utilization rate of the i-th decision-making unit, which is between 0 and 1. When it is equal to 1, the corresponding decision-making unit appears on the boundary, and its input utilization rate is 100 %,x i is a vector, y i is a vector;

[0061] s°t°-φ yi +Yλ≥0x i -Xλ≥0;

[0062] λ≥0;

[0063] In the formula, when the input conditions are given, the maximum growth rate of the i-th d...

Abstract

The invention discloses a snail capturing device and belongs to the field of aquaculture devices. The snail capturing device comprises a catching box for shoveling snails, wherein the capturing box isconnected with a receiving box through a delivery pipeline, the receiving box is connected with a collecting box through a connecting pipe, a hydrological acquisition device is arranged on the catching box, a catching data acquisition device is arranged on the collecting box, and the hydrological acquisition device and the catching data acquisition device are both connected with a computer. The hydrological acquisition device and the catching data acquisition device are utilized to acquire hydrological data and snail cage capture data, regional catching amount models are provided, excessive catching in each catching region is judged, sustainable catching is achieved, the problem of the catching mode is effectively avoided that snails are left or damaged in the catching process, and the snail catching quality is improved.

Description

technical field [0001] The invention belongs to the field of aquaculture equipment, and in particular relates to a grabbing device for snails. Background technique [0002] At present, there are many breeding areas and breeding bases for cultivating snail products. The breeding areas of these breeding areas and breeding bases are often very large. After removing the snails in the net bag of the fishing device, put them back into the water. This is not only time-consuming and laborious, but also the fishing is not clean, which is easy to cause omissions, and it is easy to damage the snails during the dragging process, resulting in economic losses. Contents of the invention [0003] The purpose of the present invention is to provide a grabbing device for snails. The invention uses the hydrological acquisition device and the capture data acquisition device to obtain hydrological data and snail cage capture data to propose a regional catch model to judge whether the fishing a...
