A kind of mudflat ship
Technical field
The present invention relates to a kind of mudflat ship.
Background technology
The Tidal Flat Resources of China enriches, China utilizes tidal land area to carry out sea-farming fairly largely in recent years, aquaculture in tideland industry is developed rapidly, achieved with huge economic benefit, but the instrument of operation and transport is more original on tidal land, the general mode all adopting foot directly to pedal the advance of hand push mudflat ship on beach carries out operation and transport, so relatively more tired, especially not only cold but also dirty and messy in operation in winter, the mudflat ship of existing a kind of improvement, such as the patent No.: 201220682898.1 disclose a kind of mudflat ship, lever is used to transmit principle, hull is made to advance by stepping on pedal, people is without walking in beach, avoid cold and dirty and messy to a certain extent, but its cost is of a relatively high.
Summary of the invention
The technical problem to be solved is to provide one makes hull advance again by pedal pedal, and people is without walking in beach, but the mudflat ship that cost is relatively low.
The present invention provides a kind of mudflat ship, including main support, steering yoke, hull, and drive the driving device of mudflat ship, it is characterized in that described main support is provided with transverse axis, described main support is connected with described hull by described transverse axis, described steering yoke lower end is provided with guiding supporting plate, described driving device includes: a connecting rod, one push rod, one pedal, one push pedal, one elastic threads, its one end of described connecting rod and described main support axle connect, its other end and described push rod shaft connect, its one end of described push rod is connected with described pedal, its other end is connected with described push pedal, its one end of described elastic threads is connected with described main support, its other end is connected with described push rod or connecting rod;
Described guiding supporting plate is provided below convex tendon;
Described big upper end, push pedal lower end is little, and described push pedal upper end is provided with cavity, and described push rod one end is arranged in described cavity, and by string screw is fixed with described push pedal;
Described hull has two, is separately positioned on the both sides of support.
The beneficial effects of the present invention is compared with the prior art: simple in construction, cost is low, hull can be made to advance by pedal pedal equally.

The title of the figures above and sequence number: 1, main support, 2, hull, 5, pedal, 7, connecting rod, 8, push rod, 9, push pedal, 11, elastic threads, 13, steering yoke, 14, guiding supporting plate, 19, transverse axis.
Detailed description of the invention
Below in conjunction with accompanying drawing, to the present invention, above-mentioned and other technical characteristic and advantage are described in more detail.
nullAs shown in the figure: a kind of mudflat ship,Including main support 1、Steering yoke 13、Hull 2、And drive the driving device of mudflat ship,Main support 1 is provided with transverse axis 19,Main support 1 is connected with hull 2 by transverse axis 19,Steering yoke 13 lower end is provided with guiding supporting plate 14,Driving device includes: a connecting rod 7、One push rod 8、One pedal 5、One push pedal 9、One elastic threads 11,Its one end of connecting rod 7 and main support 1 axle connect,Its other end and push rod 8 axle connect,Its one end of push rod 8 is connected with pedal 5,Its other end is connected with push pedal 9,Its one end of elastic threads 11 is connected with main support 1,Its other end is connected with push rod 8 or connecting rod 7,Guiding supporting plate 14 is provided below convex tendon 12,Big upper end, push pedal 9 lower end is little,Push pedal 9 upper end is provided with cavity,Push rod 8 one end is arranged in cavity,And by string screw is fixed with push pedal;When to drive mudflat ship, one feet station of operator aboard ship, another pedal pedal 5, push rod 8 and push pedal 9 are pushed to the back lower place, and push pedal 9 inserted beach makes it cannot continue to retreat, under the pressure effect of foot-plate, the angle between push rod 8 and connecting rod 7 changes, and forces connecting rod to promote hull to advance, when foot is mentioned, elastic threads push rod pull-up, then can be pedaled pedal, so go round and begin again again.
