Description
Technical field
A kind of shell seafood acquisition equipment belongs to shell seafood conveying technology field.
Background technique
Shell seafood, that is, have conchiferous mollusk, such as clam, razor clam, and this kind of seafood is usually cultivated extensively
On the beach of coastal area, in the season of harvest, usually by the way of hand digging, first loosens or take on beach
Then silt is taken out this kind of seafood.Since beach is than relatively soft, the mode efficiency of manual capture is lower, it is labor-intensive compared with
Greatly.For this problem, in the prior art, also there is corresponding capture device, but due to unreasonable, the Duo Shuocun of its own structure
It is excessively complicated, at high cost in, structure, or it is easy the problem of damage is caused to shell seafood.Influence appearance and survival rate.
Summary of the invention
The technical problems to be solved by the present invention are: overcome the deficiencies of the prior art and provide it is a kind of it is not damaged, without squeeze,
The shell seafood acquisition equipment of high efficiency conveying.
The technical solution adopted by the present invention to solve the technical problems is: a kind of shell seafood acquisition equipment, feature
Be: including capture vehicle, collecting box and spiral pumping device, the top of capture vehicle, spiral pumping device packet is arranged in collecting box
Delivery pipe is included, the top of collecting box is arranged in delivery pipe upper lateral, and lower part is vertically arranged between the rear side of capture vehicle, and delivery pipe side is set
There is the rotary excavator structure for taking silt, the bottom of collecting box is equipped with water flow mud-sand discharger；The delivery pipe is no leaf spiral shell
Pipe is pumped in rotation, and it includes multiple coaxial mounted helical feed rings that no leaf spiral, which pumps pipe, is set with water-supply-pipe outside helical feed ring
Or appendix, the interior spiral stream guidance chamber for being equipped with annular of the helical feed ring, spiral stream guidance chamber side is connected to water-supply-pipe or gas transmission
Pipe.
The present invention changes the structure type of traditional shell seafood capture transhipment, by the way of spiral extraction, benefit
With the concept of " leaf without mixing ", inside is introduced to the structure of material conveying without the helical feed ring of any paddle or stirred tank
, the water ring or compression ring of spiral are formed using helical feed ring, and gradually form and push ahead using multiple helical feed rings
Power, in the case where not needing propeller blade, one can be formed to shell seafood to form the form of screw propulsion
Suction, and due in delivery pipe and there is no the components such as guiding and stirring, so when being extracted to shell seafood, not
The damage that contact can be generated to shell seafood, realizes the conveying of the high quality of marine products such as shell seafood, and defeated
Can guarantee the formalness of shell seafood during sending to the greatest extent, will not to shell seafood have squeeze or product to
It destroys, fully ensures that the fresh and vigor of shell seafood.
Meanwhile being equipped in delivery pipe side and taking the rotary excavator structure of silt, before being extracted, root one step ahead
According to the direction of travel of capture vehicle, first beach is excavated, the silt for burying shell seafood is excavated, formed and continued
Excavation, rear is corresponding to be extracted by delivery pipe, can be in delivery pipe in order to improve the cleannes on shell surface
Spray tube is arranged in exit, carries out spray cleaning to shellfish surface, the bottom that then extra silt and water flow pass through collecting box
Before the water flow mud-sand discharger of setting is discharged, and flows back to beach, while the water flow of this part discharge again can be to direction of travel
The shoal area of side is further moistened, moreover it is possible to be reduced the occupancy volume of the silt and water in collecting box, be improved testacean
Collect quantity.
The rotary excavator structure includes two groups of fixation brackets for being vertically arranged between lower section on rear side of collecting box, two groups of fixed brackets
It is connected between lower part by the short axle being laterally arranged, rotational installation multiple groups have the runner of external tooth, the external tooth in the short axle
