Description

A device for catching water clams

technical field

The utility model relates to a device for catching water clams. The water clam is a kind of aquatic shellfish, which mainly lives on the surface or in the mud of the bottom of the water. the

Background technique

Clam fishing is a production activity of fishery producers, and fishing tools are particularly important in the production process. It involves the quality and quantity of water clams caught, as well as production costs. In the past, before the 1980s, wooden hoods or human diving were used to catch water clams, and the output was very low; in the mid-1980s, due to technological progress, a mechanization called a power pump appeared in the industry of fishing water clams. Fishing tools, its output is more than 1000 times that of artificial fishing. During the use of the power pump, although the output is high, the water clams caught are often damaged, and there are many impurities in the meat of the water clam, which affects the quality; in addition, the use of the power pump seriously pollutes the water body and destroys the natural aquatic ecological environment. It was explicitly banned by the relevant state departments in the 1980s. In the long-term production practice, through continuous exploration and summarization, I have created a new type of device for catching water clams. the

Utility model content

The purpose of this utility model is to provide a device for catching water clams. The device is small and exquisite, convenient and practical. the

In order to achieve the above object, the utility model adopts the following technical solutions:

A device for catching water clams, characterized in that a rectangular frame (1) is connected to a net pocket (2), the upper part of the rectangular frame is provided with a middle frame (3), the middle frame is connected with a stable frame (8), and the upper part of the middle frame is The rotating shaft (12) is connected with the elevating rod (4), and the end of the elevating rod is also provided with a rotating wheel (6); the lower part of the intermediate frame is provided with an adjusting rod (5), and holes (13) are respectively provided on the elevating rod and the adjusting rod , lifting rod and adjustment rod are regulated lifting with screw (7) by hole; The bottom of rectangular frame is provided with dog tooth (11). A stay rope (10) is arranged on the frame, and a buoy (9) is arranged on the middle frame. The above-mentioned components: frame, dog teeth, intermediate frame, stabilizer, elevating rod, and adjusting rod are made of steel, net pockets are made of plastic mesh, and pull ropes are made of steel wire or plastic rope. In order to improve the applicability and fishing effect, the thickness of the dog teeth is 2-4 mm, the length is 3-6 cm, and the distance between dog teeth is 6-10 mm; the mesh of the net pocket is 0.8*0.8 cm-1.5 *Between 1.5cm, the thickness of the netting bag is 9-24 plastic strands. the

The working principle of the utility model: a device for catching clams is placed in the water area to be caught, the pull rope is tied to the motor sailboat, the motor sailboat is driven to drag the device for catching clams, and the dog teeth filter out the clams above the silt. When the motor sailing boat is dragged, a current is formed, which rushes the clams to the net pocket, where the clams are washed away by the current. When a certain amount is caught, use a small boat to find the buoy and pull out the fishing device to pour out the water clams inside. In use, due to the different thickness of the underwater silt, if the silt is thick, the lifting rod needs to be adjusted downward, and if the silt is shallow, the lifting rod needs to be adjusted upward, which can be flexibly adjusted according to the actual situation during specific operations. the

The utility model has the advantages that the device for catching water clams is simple to manufacture, convenient and practical, has high fishing efficiency, and the caught water clams are fresh and alive without damage. the

Detailed ways

As shown in Figure 1, Figure 2, Figure 3, Figure 4, and Figure 5, a device for catching water clams is connected to the net pocket (2) by a rectangular frame (1), and the upper part of the rectangular frame is provided with a middle frame (3) , the intermediate frame is connected with the stabilizing frame (8), the upper part of the intermediate frame is connected with the elevating rod (4) through the rotating shaft (12), and the end of the elevating rod is also provided with a rotating wheel (6); the lower part of the intermediate frame is provided with an adjusting rod (5), Hole (13) is respectively provided with on elevating rod and regulating rod, and elevating rod and regulating rod are regulated lifting with screw (7) by hole; The bottom of rectangular frame is provided with dog tooth (11). A stay rope (10) is arranged on the frame, and a buoy (9) is arranged on the middle frame. The above-mentioned components: frame, dog teeth, intermediate frame, stabilizer, elevating rod, and adjusting rod are made of steel, net pockets are made of plastic mesh, and pull ropes are made of steel wire or plastic rope. In order to improve the applicability and fishing effect, the thickness of the dog teeth is 2-4 mm, the length is 3-6 cm, and the distance between dog teeth is 6-10 mm; the mesh of the net pocket is 0.8*0.8 cm-1.5 * Between 1.5 cm, the thickness of the mesh line of the mesh pocket is between 9-24 strands. In practical applications, it is better to make the rectangular frame with 3*5 cm steel pipes, and it is better to make the middle frame and stabilizer with 2*2 steel pipes. the
