A quantitative feeding device and a feeding machine using the quantitative feeding device

Abstract

The invention discloses a quantified blanking apparatus and a bait casting machine employing same. The quantified blanking apparatus comprises a first material canister, a second material canister, a first control gate and a second control gate, wherein the first material canister and the second material canister are coaxially arranged, the first control gate closes or opens the opening in the first material canister, the second control gate closes or opens the opening in the second material canister, and the axial relative position of the first material canister and the second material canister are adjustable. The blanking volume is determined according to the proportion of different baits. The axial positions of the first material canister and the second material canister are adjusted to change the volumes of the material canisters for receiving baits and to match with the blanking mass. The adjusting scope of bait blanking volume is large. The quantified blanking apparatus and the bait casting machine are easy to operate, and the blanking quantity can be accurately measured in gram. The automatic level and blanking precision of fishery facilities are improved, the labor intensity is lowered, the utilization rate of baits is improved, and the influence of artificial factors on culture effect is minimized.

Description

technical field [0001] The invention relates to a feeding device, in particular to a quantitative feeding device and a bait feeding machine using the quantitative feeding device. Background technique [0002] Putting feed is an important work in the process of aquaculture. The traditional feeding method is mainly manual spreading, which can only rely on manual rowing, which is labor-intensive and low in efficiency, and the consistency of feeding is poor, and the utilization rate of feed is not high. The bait will aggravate the pollution of water quality, thereby increasing the cost of breeding. At present, the artificial feeding method has been gradually replaced by the bait feeding machine feeding method that uses an automatic bait feeding machine for automatic feeding. [0003] The Chinese patent No. ZL200710054442.4 discloses an automatic quantitative bait feeding machine, which includes a controller, a base, a storage hopper above the base, and a quantitative feeding d...

AI Technical Summary

Problems solved by technology

[0004] But the above-mentioned quantitative feeding device has the following problems: the amount of each feeding is realized by adjusting the quantity of the quantitative holes, the amount of feed that is thrown in each time can only be an integer multiple of the quantitative holes, and the adjustable range of the amount of bait is less. ;In addition, a row of quantitative holes is used at the same time for each feeding. If a row of quantitative holes does not need to be fully used, it is necessary to manually block the extra quantitative holes, which is troublesome to operate.
