Description

Technical Field

[0001] The utility model relates to the technical field of net throwing devices, in particular to a projectile for a net throwing device. Background Art

[0002] Experiments with net-casting projectiles are usually designed based on the principle of horizontal projection motion. The role of net-casting projectiles usually involves accelerating the projectiles to the required speed for specific operations or experiments. In addition, net-casting devices can also be used in industrial applications, such as road shot blasting machines, which use motor-driven shot blasting wheels to generate centrifugal force and wind force during high-speed rotation to accelerate and throw projectiles for cleaning or strengthening work surfaces.

[0003] When a traditional net-casting device is casting a net, since the net is directly spread out, it takes up a lot of space. At this time, the size of the net-casting device cannot be adjusted according to demand. At the same time, the net-casting is assisted by humans, which is extremely time-consuming and laborious.

[0007] Preferably, the number of the springs is four, and the other sides of the four springs are in contact with the inner wall of the rear end cover. The four springs are used to bounce the four petals of the projectile apart after the exit.

[0008] Preferably, the replacement mechanism includes a fixing plate, the fixing plate is fixedly connected to the left side of the net bin surface, the net surface is fixedly connected with a connecting net plate, the connecting net plate is arranged on the inner side of the net bin, the left side of the connecting net plate close to the fixing plate is fixedly connected with a locking plate, the other side of the locking plate is hinged with a hinged plate, the hinged plate is fixedly connected with a clamping block close to the fixed plate, and a clamping slot is provided on the outer side of the fixed plate.

[0009] Preferably, the slot is opened on one side away from the fixed plate, and the surface of the block is engaged with the inside of the slot. When the block is removed from the slot, the connecting mesh plate can be directly pulled to drive the mesh to be replaced.

[0010] Preferably, the locking plate is arranged on the left side of the net bin, and the number of the locking plates is two.

[0011] Compared with the prior art, the utility model provides a net throwing device projectile, which has the following beneficial effects:

[0012] 1. The projectile of the net-throwing device is an integral part in the barrel by setting a projectile throwing mechanism. The rear end cover constrains the spring and prevents it from opening. When it passes through the barrel, the rear end cover is trapped in the barrel and the spring force is released. Under the action of the spring, the projectile opens into four petals, thereby driving the net to open and be thrown forward.

[0013] 2. The net throwing device projectile is provided with a replacement mechanism. When the net 31 needs to be replaced regularly, the hinged plate can be rotated on one side of the locking plate, so that the hinged plate and the locking plate are in a straight line, so that the hinged plate drives the card block to move out of the card slot. At this time, the connecting net plate can be directly pulled to drive the net to be replaced. BRIEF DESCRIPTION OF THE DRAWINGS
