Forage smashing device for breeding herbivorous fishes

Abstract

The invention discloses a forage smashing device for breeding herbivorous fishes. The forage smashing device comprises a machine base, a smashing groove is formed in the upper end of the machine base,a feeding pipe communicated with the smashing groove is arranged at the left end of the machine base, a stepping motor is arranged at the right end of the machine base, a rotating shaft is in keyed joint with an output shaft of the stepping motor, and rotating blades facing the feeding pipe are evenly distributed at the left end of the rotating shaft in the circumferential direction; and two crushing rollers which are matched with each other are symmetrically arranged at the lower end of the smashing groove front and back, the output shaft of the stepping motor is in keyed joint with a firstgear, and one crushing roller is in keyed joint with a second gear connected with the first gear through a tooth-shaped conveying belt. The forage smashing device has the advantages of being reliablein structure, capable of automatically and continuously completing chopping, crushing, pushing out of crushed forage, popping up of the crushed forage and resetting, capable of adjusting the popping-up distance and dispersion degree of the crushed forage, thorough in crushing, time-saving and labor-saving.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a forage crushing device for aquaculture herbivorous fish. Background technique [0002] In the cultivation of herbivorous fish, grass is usually fed to the herbivorous fish, and the grass needs to be chopped before it can be eaten by grass carp. However, it is time-consuming and labor-intensive to process the grass manually, and it is easy to be cut during the cutting process. It is thorough and the debris is splashed, making it difficult for herbivorous fish to eat. Contents of the invention [0003] The main purpose of the present invention is to provide a forage crushing device for cultivating herbivorous fish, which has a reliable structure, can be automatically and continuously chopped and then crushed, and the crushing is thorough without causing fragments to splash, saving time and effort. [0004] In order to achieve the above purpose, the technical solution adopted by the ...
