Embodiment Construction

[0019] Such as figure 1 The combined discharge device shown includes a discharge unit 1 , a flow unit 2 , a bracket unit 4 and a notch unit 3 respectively with telescopic functions, and the discharge unit 1 , flow unit 2 and notch unit 3 are connected in sequence from high to low. The discharge unit 1 includes two discharge rods parallel to each other. A concave discharge layer is provided between the two discharge rods. The discharge rod includes a first discharge rod 12 and a second discharge rod 13. The first discharge rod 12 is arranged along the axis. There is an installation hole, and the second discharge rod 13 is slidably connected in the installation hole, and the staff controls the telescopic length of the discharge unit 1 by sliding the second discharge rod 13 . The first discharge rod 12 is also provided with a discharge rod locking device 14, which is locked by the discharge rod locking device 14 when the second discharge rod 13 slides to a proper position.

Abstract

The invention discloses a combined-type releasing device comprising a releasing unit, a flowing unit, a support unit and a notch unit which are all telescopic; the releasing unit, the flowing unit and the notch unit, in the telescopic direction, are respectively provided with sliding chutes which can be used for releasing fries; the releasing unit and the notch unit are detachably connected to two ends of the flowing unit; the sliding chutes of the releasing unit, the flowing unit and the notch unit are successively communicated to form a releasing tank; the support unit is detachably connected to the bottom of the flowing unit. Through splicing the releasing unit, the flowing unit, the support unit and the notch unit to form a releasing device, the releasing device is portable and can be adjusted according to actual releasing water area situations and geography. The telescopic releasing unit, the flowing unit, the support unit and the notch unit make it possible for workers to freely stretch out and draw back the device according to the distance between the fries and the releasing water area. The device of the invention can be applied in enhancement and releasing field.

Description

technical field [0001] The invention relates to a discharge device, in particular to a combined discharge device. Background technique [0002] At present, the enhancement and release of fishery resources is one of the effective measures to restore the declining marine fishery resources, optimize the production structure of fishery resources, and improve the ecological environment of sea areas. The release tank is one of the important tools commonly used for the proliferation and release of fishery resources, and it is used to release seedlings from land to fixed waters. Existing launder device is a kind of semicircular cylinder. The disadvantages of this device are: (1) it is not convenient to carry, the structure is fixed, and it is difficult to make adjustments according to the actual discharge waters and terrain; (2) the single notch, the discharge efficiency is low, it takes a long time, and it is easy to cause operator fatigue; (3) ) can only be used for fixed-point ...
