Conveying-chain stacking device and method for seedling plugs

Abstract

The invention discloses a conveying-chain stacking device and method for the seedling plugs. The device comprises a rack, a plug conveying mechanism, plug lifting mechanisms and a lifting drive mechanism, wherein the plug conveying mechanism is arranged at the middle part of the rack, the plug lifting mechanisms are arranged at the two sides of the plug conveying mechanism separately, and each plug lifting mechanism is connected with the lifting drive mechanism; and in each plug lifting mechanism, a plurality of plug lifting elements are arranged on a rotary conveying assembly, and the distance between each two adjacent plug lifting elements is greater than the height of a single plug. The method comprises the following steps: the planes of the two sides of each plug to be stacked are supported by virtue of the plug lifting mechanisms, the plugs to be stacked are lifted and separated one by one, after the number of the lifted plugs reaches a set number, the plug lifting mechanisms reversely descend by a certain height, and the lifted plugs are sequentially stacked onto a conveying belt and conveyed out by the conveying belt. The conveying-chain stacking device and method for the seedling plugs are capable of effectively increasing the stacking efficiency for the plugs, stable in working, low in impact vibration action on matrixes and seeds in the plugs, and applicable to high-speed sowing working production.

Description

technical field [0001] The invention relates to the technical field of industrial seedling raising and sowing production, in particular to a conveying chain-type seedling raising tray stacking device and method. Background technique [0002] The stacking of seedling trays is the last operation link in the industrial seedling cultivation and sowing production. The seedling trays that have been sown, covered with soil and sprayed with water are stacked into stacks to facilitate subsequent transportation to the nursery room. Domestic industrialized seedling raising and seeding production lines have mature operating equipment in the tray matrix filling, hole pressing, sowing, soil covering, and spraying water operations, but there is still a lack of practical and efficient operating equipment in the tray stacking link. At present, the seedling factories mainly Still rely on manually picking and placing the seedling trays one by one, the frequency of taking and placing actions is...

AI Technical Summary

Problems solved by technology

[0004] However, the automatic stacking devices disclosed in the above-mentioned publications all have the following common disadvantages: during the stacking process, each time a tray is lifted, the lifting mechanism needs to reciprocate once, and the trays to be stacked are stacked one by one to the previous hole. Above or below the plate, the number of lifting trays gradually increases during the stacking process, until the stacked number reaches the set value, and then a group of stacked trays are sent out as a whole

The lifting mechanism needs to be stacked with the reciprocating movement of the trays one by one, which is inefficient and complicated. The multiple reciprocating movements of the lifting mechanism during stacking will cause greater impact and vibration on the matrix and seeds in the trays, affecting the subsequent seedling cultivation. Quality, it is difficult to adapt to the requirements of high-speed sowing operations
