Stereo fine cultivation technique of shrimp, crab and shellfish in sea water pond

InactiveCN101347106AIncrease profitPrevent each otherClimate change adaptationPisciculture and aquariaPrawnWater quality

An three-dimensional intensive culture technique of shrimps, crabs and shellfish in a seawater pond comprises the following steps: the pond is cleaned up before stocking, the bottom of the pond is solarized, a central canal and a circular canal are excavated, and feed water is disinfected and sterilized with medicines; fresh seawater is fed, the water quality culture, fertilization and algae culture are carried out, a lifting device for a swimming crab breeding cage is prepared, and lines are parallel set up at the two ends of the culture pond with each line spaced 50cm; and 30cm higher than the surface of the water, the cage is suspended every 50cm, the inside of the cage is provided with fine sand, the outside of the cage is sheathed with a plastic netting, benthonic seashells are put into the cage for the first, and the stocking density is 30 benthonic seashells per mu, then the stocking of prawns is carried out, and the stocking density is 5000 prawns per mu. By adopting the three-dimensional multi-species hybrid culture technique of shrimps, crabs and shellfish in a seawater pond, the water layers of the stocking ponds can be fully utilized, the utilization rates of each water layer of the stocking ponds, stocking devices and manpower are further improved, the water purification capacity of the seashell can be fully utilized, and the swimming crabs are suspended in a cage, thus avoiding cannibalism and catching and killing the shrimps and seashells in the same pound; Furthermore, the three-dimensional intensive culture technique provides adhesion and sheltering objects for prawns, and achieves the purposes of improving yield and increasing economic benefits.

Fruit and vegetable classifying and boxing robot and method

InactiveCN106314859APrevent each otherFully automaticSievingScreeningAgricultural engineeringUltimate tensile strength

The invention discloses a fruit and vegetable classifying and boxing robot system. The fruit and vegetable classifying and boxing robot system comprises a feeding mechanism, a classifying mechanism, a fruit and vegetable conveying belt, a double-arm mechanical hand, a box body conveying belt, a lifting type conveying belt, a boxing conveying belt and a fruit and vegetable carrier conveying belt, and spherical fruit and vegetable classifying and double-arm robot boxing processes are mainly completed. According to the classifying mechanism, a pitch limiting screw rod is used for distinguishing a low-level fruit and vegetable treatment area, a middle-level fruit and vegetable treatment area and a high-level fruit and vegetable treatment area through a variable-pitch guiding groove structure. The double-arm mechanical hand comprises an end picker, a motor, a steering device, a horizontal lead screw, a vertical lead screw, a polished rod, a connecting plate, a synchronous belt wheel assembly, a suction cup and the like and is installed on two work stations of a moving seat to achieve automatic layering boxing of fruits and vegetables. According to the fruit and vegetable classifying and boxing robot system, multiple processes of spherical fruit and vegetable feeding, classifying, layering boxing and the like are organically combined, full-automatic production of the fruits and the vegetables is achieved, the production efficiency of the fruit and vegetable sorting and boxing operation is effectively improved, and the labor intensity of manual production is lowered.
