Seashell digger

Abstract

The invention discloses a seashell digger which is an automatic ship type digging machine widely applicable to digging seashell products such as razor clams, clams and sea cucumbers on intertidal zones of coastal areas. The seashell digger structurally mainly comprises a ship, a driving machine, a crane, a mud filter wheel, a hydro-extracting wheel, a conveyor and the like. The mud filter wheel comprises a mud axle, rowed claws, claw nails and the like, the ship can be pushed to forwardly run under the rotation action of the mud filter wheel, an elbow is further arranged at the tail end of each claw nail of the rowed claws, and working clearance is reserved between the elbows of each two adjacent claw nails, so that seashells can be automatically dug when the mud filter wheel rolls forwardly. The seashell digger has the advantages that the digger is low in manufacturing cost and is effectively adaptive to severe working environments; the seashell digger only needs to mechanically run forwardly, so that the seashells can be quickly, accurately and efficiently dug on a large scale, and the labor intensity of manual operation can be greatly relieved.

Description

technical field [0001] The invention relates to a mining machine for collecting seashell products such as razor clams, clams, sea melon seeds and the like, that is, a seashell mining machine. Background technique [0002] Seashell products such as razor clams, clams, and sea melon seeds are widely cultivated on the tidal flats in coastal areas. Because of their delicious taste, rich nutrition, and moderate price, they have also become seafood that is often eaten on people's tables. Whenever the harvest season comes, the farmers will pick up baskets, bamboo baskets and other tools, and step barefoot on the tidal flats to dig out seashells one by one by hand. On the Internet, not only the collection speed is slow and the efficiency is low, but also the collection process has high labor intensity, great physical exertion, and the human body is prone to fatigue. The published Chinese patent No. 201320080386.2 is "a clam collector", which discloses a mechanical device suitable f...

Problems solved by technology

However, in the actual use process, there are still many defects in this mechanical equipment. First, the structural design of the whole machine is relatively complicated and precise, which is not only expensive to purchase, but also easily damaged after long-term use in harsh tidal flat environments; It is easy to break in the dragging state, and the size of the collected clams cannot be controlled, and it is very easy to collect mud or stones of equal size together, causing troubles in later removal and cleaning
