Embodiment 1

[0030] Refer to attached Figure 1~6 : a shellfish catch device, comprising a catch car 7, a collection box 10 and a screw pumping device, the collection box 10 is arranged on the top of the catch car 7, the conveying pipe 8 top is horizontally arranged on the top of the collection box 10, and the bottom is vertically placed on The rear side of the capture vehicle 7 and the side of the conveying pipe 8 are provided with a rotary excavating mechanism for digging up silt; the conveying pipe 8 is a bladeless spiral pumping pipe, and the bladeless spiral pumping pipe includes a plurality of coaxially installed spiral conveying rings 4. The spiral conveying ring 4 is externally fitted with a water pipe or an air pipe, and the spiral conveying ring 4 is provided with an annular spiral diversion chamber 403, and one side of the spiral diversion chamber 403 is connected to a water pipe or an air pipe.

[0031] The rotary excavation mechanism includes two sets of fixed brackets 11 vert...

Embodiment 2

[0041] The diameters of the plurality of spiral conveying rings 4 gradually increase. A plurality of spiral conveying rings 4 are equipped with stepped tubes, the stepped tubes are double-layered tubes, a water delivery chamber 3 is formed between the double-layered tubes, and the water delivery chamber 3 communicates with the screw conveying ring 4 . A filter screen is provided at the water inlet end or the water outlet port of the spiral conveying ring 4 . Other settings and working process are the same as in Example 1.

Abstract

The invention relates to a device for catching shellfish, and belongs to the technical field of shellfish transport. The device is characterized by comprising a collecting box (10) arranged on the topof a catching vehicle (7), the upper part of a conveying pipe (8) is horizontally arranged above the collecting box (10), the lower part is vertically arranged on the rear side of the catching vehicle (7), and a rotating digging mechanism for digging sediment is arranged on one side of the conveying pipe (8); the conveying pipe (8) is a blade-free spiral pumping pipe, the blade-free spiral pumping pipe comprises a plurality of coaxial spiral conveying rings (4), the spiral conveying rings (4) are externally sleeved with water conveying pipes or gas conveying pipes. According to the invention,the plurality of spiral conveying rings are used to form a forward advancing force, and a suction force to the shellfish can be formed without the need of a propeller blade, and contact damage to theshellfish is not caused, thus fully ensuring the freshness and vitality of the shellfish.

Description

technical field [0001] A shellfish catching device belongs to the technical field of shellfish transportation. Background technique [0002] Shellfish, that is, molluscs with shells, such as clams, razor clams, etc. This type of seafood is usually widely farmed on the tidal flats in coastal areas. During the harvest season, manual excavation is usually used to loosen or dig the tidal flats first The silt on the top, and then remove this type of seafood. Due to the relatively soft tidal flats, manual capture is less efficient and labor intensive. In view of this problem, in the prior art, there are also corresponding capture devices, but due to their unreasonable structure, most of them have the problems of too complicated structure, high cost, or easy damage to shellfish. Affect appearance and survival rate. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a shellf...
