Combined jet aerobic cultivator

Abstract

The invention belongs to the technical field of aquiculture technical equipment, in particular to a combined flow-jetting and oxygenation water-plowing machine, which comprises flow-jetting aerators; more than two flow-jetting aerators are circumferentially and uniformly distributed on a rack by taking a center shaft as a rotary center; the central shaft and a bracket are arranged on a float body; a water-plowing board is arranged on the bracket or the float body; the flow-jetting aerators are electrically connected to a computer frequency-converting control system; the water-plowing board is connected to the rack or the float body through an angle spring; and an entry angle for mounting a flow-jetting pump of the flow-jetting aerator and a centre line included angle are all adjustable. The water-plowing machine has oxygenation and water-plowing functions; the flow-jetting aerators can be used for increasing emergency oxygen by rotating around the center shaft at a high speed in the water, and also can be used for performing water-plowing rotation with a low speed of 7-10 r/min under the control of the computer frequency-converting control system; the water-plowing machine is low in manufacturing cost and good in oxygenation and water-plowing performances and is applied to the field of aquiculture.

Description

Technical field: [0001] The invention belongs to the technical field of aquaculture technology equipment, in particular to a combined jet flow aerobic cultivator. Background technique: [0002] The development goal of aerator technology is to use the minimum power consumption to achieve the best aeration and breeding benefits; farming water technology and jet flow high-speed aeration are two representative technological frontiers, and the former is a representative of energy-saving aeration for water exchange. , the latter is a more practical model for rapid oxygenation. [0003] What the patent 200620056046.6 invented is exactly the present common tillage machine. Its technology uses a complex DC motor deceleration mechanism to realize 7-10 rpm to drive the water body to generate motion and three-dimensional circulation, which promotes the replacement and renewal of surface water and bottom water, so that plankton can multiply and provide more fish and shrimp.

Problems solved by technology

[0005] However, the current tillage machines have the following shortcomings: first, the system cost is relatively high, generally 7000-8000 yuan, and nearly 3800-4000 yuan after the national agricultural machinery subsidy, so it limits the purchase of farmers; second, there is no emergency Aerator capacity, the measured oxygenation effect is only 0.1kg02 / (h.kW); when fish floating head occurs, it is necessary to rely on the traditional water wheel or impeller aerator (oxygenation capacity 2.6kg / h)

[0007] However, the current jet-type aerator also has disadvantages in use: it is generally fixed on four columns, and can only jet in one direction, and cannot realize automatic rotation or fan-shaped rotation
