Detailed Description

It should be noted that the description and sequence of descriptions of specific structures in this section are merely illustrative of specific embodiments and should not be construed as limiting the scope of the invention in any way. Furthermore, the embodiments in this section and the features in the embodiments may be combined with each other without conflict.

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the novel earthworm sucking device comprises a cover body 3 and a measuring cup 1 which are sleeved with each other and can form a sealed cavity, wherein a plurality of through holes 2 are formed in the surface of the measuring cup 1, a gas connecting hole 4 is formed in the cover body 3, and the gas connecting hole 4 is connected with an external negative pressure device 5.

Specifically, the graduated flask 1 inlays and locates in the cover body 3, both openings are towards same direction, and opening junction accessible integrative stamping forming, perhaps reach sealing connection's purpose through sealing member etc.. When earthworms need to be sucked, the negative pressure device 5 sucks air, vacuum negative pressure is formed in the cavity between the cover body 3 and the measuring cup 1 connected with the negative pressure device, the air in the measuring cup 1 is sucked along the through hole 2, the aim of safely sucking the earthworms is further achieved, and when the measuring cup 1 is filled with the earthworms, the aim of sucking the earthworms with the preset weight parts is achieved. According to the formula: m (earthworm mass) = p (earthworm density) V (earthworm volume), the earthworm volume is the volume of the measuring cup, so the weight of the earthworm can be sucked by using negative pressure only by defining the volume of the measuring cup 1.

As the optimization of the device, the measuring cup 1 and the cover body 3 form a hemisphere with a downward opening, and the measuring cup 1 and the opening of the cover body 3 are integrally formed by punching; or the measuring cup 1 is hemispherical, the outer wall of the opening is provided with a convex thread 6, the cover body 3 is hemispherical, the inner wall of the opening is provided with a concave thread 7, and the convex thread 6 and the concave thread 7 can be screwed mutually to form a sealed cavity between the cover body 3 and the measuring cup 1. Specifically, the spherical shape is arranged, and because the stress of the spherical surface is uniform, the suction force generated by negative pressure can be uniformly applied to the whole measuring cup 1, so that the earthworm sucking effect is better.

As another optimization of the device, the measuring cup 1 and the cover body 3 form a cylinder with a downward opening, and the measuring cup and the opening of the cover body are integrally formed by punching; or the measuring cup 1 is cylindrical, and a convex thread 6 is arranged along the outer wall of the opening; the cover body 3 is cylindrical, the inner wall of the opening is provided with a concave thread 7, and the convex thread 6 and the concave thread 7 can be mutually screwed to form a sealed cavity between the cover body 3 and the measuring cup 1. In particular, this configuration also makes the action of the negative pressure more uniform by virtue of the arched outer faces of the cylinders themselves.

In addition to the above two forms, the measuring cup 1 in the device can be set to different volume specifications according to different use requirements or environments. In addition, because the earthworms have different sizes, the through hole 2 in the device is preferably a through hole which is not easy to penetrate through by the earthworms and has the aperture of 0.5 mm-1 mm.

The negative pressure device 5 in the device is a manually operated needle cylinder, and the head of the needle cylinder is connected with the gas connecting hole 4 through a gas pipe. Or, the negative pressure device 5 is an air pump, the air pump is connected with the air connecting hole 4 through an air pipe, and the needle cylinder or the air pump can realize intelligent operation.
