Description
Technical field
The present invention relates to a kind of mechanized harvesting techniques of beach clam and equipment, belong to beach clam harvesting technique neck
Domain.
Background technique
Clam is also known as clam, belongs to Bivalvia curtain clam mesh Veneridae, is one of the main economic shellfish of China.Its shell
Slightly triangular in shape, ventral margin is rounded, and chitin is hard thick, and two shells are equal in magnitude, and the inner bay that fresh water injects is lived in happiness and river mouth is attached
The areas such as close thin sandy beach and intertidal zone.
Clam is embedded type shellfish, is distributed in the intertidal zone of littoral inner bay near flatter sea (river) mouth, and shallow more
In the fine sand of sea region, silt beach, the drilling effect by abdominal foot has latent husky habit.Depth is inhabited with water temperature and Individual Size and
Different, the latent depth that occupies of 2-3cm clams is 6-8cm when winter, and 4-6cm clams are latent that occupy depth be then 12cm or so.Summer Gao Shui
Wen Qi is inhabited on the beach surface layer less than 1cm depth, and water temperature in winter is low, inhabites depth up to 10-20cm.Weather-stable is warm
When stretch that it makees active operation enough；It is then slipped into sand mud when cold, mud depth of diving is generally at 5-25 centimetres.
Harvesting clam mode has artificial and two kinds of mechanical harvesting in the prior art.
Country clam producing region mostly uses manual work at present, mainly by outside stimulus so that silt layer become to relax it is dilute
It drops down, ensconces clam therein and also just lose sand bed protection, expose the surface, then be collected pickup.Specific collecting method: work as tidewater
After recessing beach face, beach sand ground vibrate by simple self-made sledge or clappers and presses effect of stepping on or is inserted into iron plane or creeper
Creeper is retreated by certain inclination after beach face certain depth, when clam drills out sand bed because jamming on, i.e., is received with three hooks or trawlnet
Collection picks.
The biggish area of small part clam yield then carries out machinery to beach using the bucker-type collecting cart of repacking formula and is turned into
Industry, setting scraper bowl are inserted into sand ground depth, sandy soil are scooped up together with clam, then by internal transport mechanism and sub-sieve mechanism to text
Clam is sieved with silt, clam is uniformly collected into collecting box, silt then device for transferring.For the clam of low tide intertidal zone
Collection mode is salvaged using fishing boat trawl type in harvesting, northern some areas, breaks ground and fishes with principles of hydrodynamics design
Two parts device when fishing, beach silt layer is uniformly removed by high pressure water flow, and mud, shellfish are poured collection shellfish case, then through separator
Silt, young shellfish are isolated, then commodity shellfish is fished by fishing device and is transported on ship.
The above mechanized harvesting job area is wide, production capacity is high (fishing 30~50 times of work efficiency manually to net rake), but spiral shell
Paddle trawling is revolved, since blade can directly hit clam, breakage rate is higher；And a large amount of earthmoving type screenings harvest and high pressure water
Stream easily causes beach earth formation to change beach percussion, and the migration of silt layer not―rationality causes silt layer to be unevenly distributed,
Ecological environment can be seriously affected under long term, need the smooth repair of subsequent progress beach.
Summary of the invention
The technical problem to be solved in the invention is: the mechanized harvesting technique of existing beach clam, and blade can be direct
Clam is hit, breakage rate is higher；And a large amount of earthmoving types screening harvestings and high pressure water flow to beach percussion with easily causing beach
Layer structure change, silt layer not―rationality migration, causes silt layer to be unevenly distributed, ecological ring can be seriously affected under long term
Border needs the smooth repair of subsequent progress beach.

Flood the operating mode of sandy soil layer in tidewater: mechanical oscillation array does not work, and array all occurs by ultrasonic wave and shakes
It starts building to make, ultrasonic wave in varying numbers is opened according to the depth of water, array occurs, can be the longitudinal array in front and back, enhance ultrasonic activation
Effect is also possible to the horizontal array of left and right, increases operation area range；
It is decorporated under the operating mode for exposing sandy soil layer in tidewater, mechanical oscillation are worked at the same time with ultrasonic activation；
In the sandy soil region far from seawater or array can not be occurred into for ultrasonic wave and all removed under the mode of make-up water source condition,
Multiple groups mechanical oscillation array is changed into work.
9. a kind of recovery process of mechanized harvesting equipment as claimed in claim 7, it is characterised in that:
Mudflat operation mode: decorporating completely in tidewater or not before flood tide, during sandy soil layer exposes the surface on beach, tractor is first
Voluntarily to supply water body at seawater into water tank；When harvesting, power buggy is preceding, with 60-90m/min of speed advance, after
Array mechanism occurs for continuous mounting mechanical oscillation array walking mechanism and ultrasonic wave；Vibrating mechanism is operated by camshaft mechanism,
Having a rest property generates down force, carries out continuous shaking hammering to sandy soil ground, changes sandy soil layer density by external force, with
Followed by ultrasonic wave array occur start ultrasonic signal generator, working frequency 20-60KHZ generates high-frequency signal to being changed
High-frequency signal is converted into ultrasonic activation by energy device, energy converter, makes exciting plate that water be pushed to make ultrasonic activation, in double action
Under, the clam under sandy soil drills out in sand rapidly, is exposed to above soil layer；Exciting front edge of board is arranged for rooting out beach protrusion sand
The flat membrane pressure sensor for pushing away husky shovel board and detecting depth of accumulated water on beach of stone, flat membrane pressure sensor are arranged apart from beach
It applies at ground 5-10mm height, when there is ponding on beach, flat membrane pressure sensor immerses in ponding, can be according to pressure signal
Size judges the depth of ponding；Spray pump work is automatically controlled according to the pressure signal value of setting；When flat membrane pressure sensor is surveyed
It obtains and is lower than 10mm without ponding or water level on beach, spray pump startup, spray water body, filled between ultrasonic wave excitation plate and sandy soil layer
Full water medium, realization enter conduct vibrations in sandy soil；Such as measure that water level above sandy soil is continual and steady, and ultrasonic wave excitation plate can be complete
It is immersed in water, then stops spraying；
Underwater work mode: when operation area is flooded by tidewater, and water level is no more than 500mm, and tractor is directly entered operation area, with
90-120m/min of speed advances, and array occurs for mounting ultrasonic wave after vehicle, and working frequency 60-100KHZ is direct by exciting plate
By effect of vibration in underwater.
