Abstract

The invention discloses a pneumatic control net casting device based on a Laval tube. The pneumatic control network casting device comprises a supporting device, a gas storage device connected with the supporting device and a transmitting device connected with the gas storage device. The pneumatic control net casting device has the benefits that through a lot of experimental screening, an existing traditional human net casting finishing mode is broken through, and the pneumatic control net casting device supported by adopting the advanced Laval nozzle as casting power is provided; the pneumatic control net casting device is safe, stable and effective in pneumatic control, high in performance and precision and convenient to use, the working efficiency can be greatly improved, and the various defects in the prior art are overcome.

Description

technical field [0001] The invention relates to a device for realizing long-distance throwing of nets, in particular to a pneumatically controlled net thrower based on a Laval tube, which can realize long-distance throwing and throwing of fishing nets. Background technique [0002] In the traditional fishing method, the fishing nets are thrown manually, which is not only inefficient, but also labor-intensive, which is increasingly unable to meet the requirements of modern fishery development. However, it is also difficult to find tools or equipment for automatically throwing fishing nets on the market, so it can only be considered to replace manual rope throwing devices. [0003] In the current technical field, the devices for throwing ropes include rifles or pedestal type rope shooting guns and arrows. This type of rope shooting gun still has a relatively large range, but because the gunpowder used as the energy source is consistent with the principle of the guns used in w...
