The invention relates to a conveyor machine with a steeply rising support (1), on which a chain (51-55) fastened as the forward and return strands (2) is displaced with buckets (50), on which the chain wheel (4) is attached at the loading point, the chain wheel 3 at the discharge point and a chain wheel (5) at each intermediate stage. Such a conveyor system has several advantages. I'd like to mention a few of them: 1. Due to the series connection, the conveyor has only one loading and unloading process and therefore a much higher efficiency, since there is no friction between the material being conveyed and the conveying element (vane pumps, centrifugal pumps, Archimedes screws, etc.). 2. The conveying direction can be reversed by making minor changes to the discharge unit (5) and the feed unit (4). 3. This feature also allows the hoisting machine to be used in storage power plants. It's not always necessary to pump water up and down (using pumped storage). (A storage power plant always requires a hoisting system.)

The invention discloses a fishing vaccine continuous soaking inoculation method based on the Archimedes screw principle. The fishing vaccine continuous soaking inoculation method comprises the steps that fish schools and vaccine soaking liquid are synchronously conveyed to a cavity formed between a soaking cylinder and an oxygen pumping shaft pipe through a sliding way; the oxygen pumping shaft pipe and the soaking cylinder are divided by the spiral blades to form independent cavities, so that fish schools with proper density are continuously propelled and uniformly soaked in compartments according to a set propelling speed; the oxygen dissolving level of the vaccine soaking solution is dynamically maintained through the oxygen pumping shaft tube; the fish school state is monitored in real time based on an image acquisition device, and abnormal individuals are marked; the vaccine soak solution is recycled through the separation grid plate and the recovery system. The problems that traditional artificial inoculation is large in batch difference, low in inoculation efficiency, unstable in dissolved oxygen and large in fish school stress are solved.

This addition concerns a sequential slide-type device on an Archimedes screw with a flexible-bottom hopper. Its purpose is to control the volume and weight of grain to be processed, as well as the corresponding volume of liquid. The control system can be electric, hydraulic, or pneumatic, the objective remaining the same: counting pulses related to a predetermined quantity of grain to be processed, in conjunction with a liquid metering device that dispenses the corresponding quantity. This addition consists of a grain receiving hopper 1 with its safety grid 2. The cylinder 3 pushes the piston and the hopper's closing plate, emptying the grain contained in the slide into the receiving chamber of the hopper screw, and then immediately returns to its starting position. The slide capacity is adjustable via the gate 5, and the pulse frequency (piston strokes) is also adjustable by setting a timer located in the control cabinet 7 with a counter 8.A remote control device located near the piston will allow the descent of a predetermined quantity of liquid 9.
