Detailed Description
For the purpose of making apparent the objects, technical solutions and advantages of the present utility model, the present utility model will be further described in detail with reference to the following examples and the accompanying drawings, wherein the exemplary embodiments of the present utility model and the descriptions thereof are for illustrating the present utility model only and are not to be construed as limiting the present utility model. It should be noted that the present utility model is already in a practical development and use stage.
The present utility model will be described in further detail with reference to examples.
Example 1
As shown in fig. 1 to 4, the utility model provides a sewage sucking head for a sewage sucking device of a fry rearing pond, which comprises a sucking head 1, wherein the sucking head 1 is hollow and tubular, the upper end of the sucking head 1 is provided with a connecting part 3, and the outer wall of the sucking head 1 is fixedly connected with an isolation cover 2 for isolating a fry group. The cultivation of the fries is generally carried out in a circular cultivation pond with the depth of 0.4 meter and the diameter of 2 meters or a rectangular cultivation pond with the side length of 2 meters, broken tubificidae are usually used as an initial bait 3 to 7 days after the fries are subjected to film emergence (namely from an opening to a feeding period), tubificidae is mainly used in the early feeding period, compound feed is used as an auxiliary material, during the period, the water flow in the cultivation pond cannot be too large due to the weak constitution of the fries, and residual tubificidae baits and excrement at the bottom of the pond cannot be timely discharged through water flow, so that the fries can be cleaned manually. The dirt absorbing equipment in the prior art does not have the effect that the fish fry is sucked out in the dirt absorbing process, and the fish fry, the residual bait and the excrement are easily sucked out together, so that the fish fry is injured or even die. Accordingly, the applicant has proposed a soil pick-up head of a soil pick-up device capable of avoiding sucking out fish fries during soil pick-up.
The specific operation process is as follows: firstly, the suction head 1 of the utility model is connected with a sewage sucking device through the connecting part 3 at the upper end, and can also be connected with a siphon, then the area to be cleaned is determined, the suction head 1 is put into a pool, the fish shoal can avoid the suction head 1 because of habit, at the moment, the residual bait or the excrement is covered by the isolation cover 2, the suction head 1 is tightly attached to the bottom of the pool, the fish shoal is isolated, and the fish fry can not be sucked out by starting the switch of the sewage sucking device to clean. Preferably, the shielding cover 2 is made of transparent soft foam material, the soft foam material can not hurt fish shoals even though the soft foam material is carelessly collided with the fish shoals, and the transparent material can more clearly observe the situation in the shielding cover 2, so that the situation that the fish fry restarting switch does not exist in the shielding cover 2 is ensured. The horizontal section of the isolation cover 2 is circular, so that the side wall area of the circular cultivation pond is conveniently cleaned, and if the isolation cover 2 is a rectangular cultivation pond, the horizontal section of the isolation cover 2 can be also set to be triangular or rectangular, so that the corners of the cultivation pond are conveniently cleaned.
The connecting portion 3 includes a first connector 31 and a second connector 32, threads are provided on outer peripheral walls of the first connector 31 and the second connector 32, and the first connector 31 and the second connector 32 are fixedly connected. Preferably, the diameter of the first connector 31 is 8mm, and the diameter of the second connector 32 is 10mm. The connecting portion 3 includes a plurality of connectors, and every connector sets up to different diameters for connecting portion 3 has better application scope, in this embodiment, dirt absorbing equipment is the connecting pipe homoenergetic of 8mm or 10mm diameter with this dirt absorbing head adaptation. Meanwhile, the outer peripheral walls of the first connector 31 and the second connector 32 are provided with threads, and the first connector and the second connector can be connected in a buckling manner, so that the first connector and the second connector are convenient to detach and replace.
As shown in fig. 3, the projection line of the lower end surface of the suction head 1 forms an angle α with the central axis of the suction head 1, and α is not equal to 90 degrees. According to the scheme, the dirt sucking port on the lower end face of the suction head is arranged to be an inclined face, so that the cross-sectional area is increased, and the dirt sucking efficiency is greatly improved.
As shown in fig. 3, the lower end surface of the isolation cover 2 is fixedly connected with bristles 5, and the bristles 5 are perpendicular to the ground. It should be noted that, the bristles 5 are preferably rubber bristles 5, and the overall vertical cross-section of the free end with the movable bottom is provided with a wavy shape. The structure can enable the excrement or residual bait outside the isolation cover 2 but near the isolation cover 2 to enter the isolation cover 2 through the gaps of the wavy bristles 5, so that the dirt absorbing efficiency is further improved. The length of the brush hair 5 is preferably 1cm, and the rubber soft brush hair 5 is convenient to move underwater and can ensure that the fish fry is not injured. In addition, the isolation cover 2 provided with the brush hairs 5 has an active cleaning function, can brush dirt at the bottom of the pool, and then sucks the dirt away through the suction head 1.
Example 2
The bottom of the isolation cover 2 is provided with a bump 21, the bump 21 is sleeved with a sucker 4, and the side wall of the sucker 4 is provided with an air inlet 41. The sucking disc 4 is sleeved on the convex block 21, and the sucking disc and the convex block can slide relatively while keeping a certain friction resistance state. As shown in fig. 4, the suction cup 4 is forced downwards, at this time, water and air in the suction cup 4 are squeezed out, the air inlet holes 41 are completely blocked by the downward sliding lugs 21, and negative pressure is formed in the suction cup 4, so that the suction cup 4 is tightly adsorbed on the bottom of the pool, and the suction head 1 is more stable in the dirt sucking process. When the dirt sucking area needs to be replaced, the upward force is applied, as shown in fig. 5, at the moment, the lug 21 slides upwards until the air inlet hole 41 is opened, water outside the sucking disc 4 enters the sucking disc 4 through the air inlet hole 41 due to the internal and external pressure difference of the sucking disc 4, and when the pressure balance sucking disc 4 loses the adsorption capacity, the suction head 1 is taken down, and the dirt sucking area is reselected.
The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the utility model, and is not meant to limit the scope of the utility model, but to limit the utility model to the particular embodiments, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the utility model are intended to be included within the scope of the utility model.
