Chain length matching device and matching method

Abstract

The invention discloses a chain length matching device. The chain length matching device comprises a box body; the sidewall of one side of the box body is provided with an upper row of tensioning wheels and a lower row of tensioning wheels; a to-be-measured chain surpasses all tensioning wheels; the chain length matching device further comprises a wall pulley and an adjusting bracket; the wall pulley and the adjusting bracket are fixed to the same side of the sidewall; one end of the chain is connected to the adjusting bracket; and the other end of the chain is connected to the wall pulley. Bypulling the adjusting bracket, the chain can be gradually tightened; this pulling force can be measured via the wall pulley; and when the force measured by the wall pulley is equal to a set value, the corresponding reading of one end of the chain at the position of the adjusting bracket can be recorded to obtain the length of the chain. By measuring the length of all chains of the same batch, thelength of all chains can be obtained; according to the measured readings of the chains, the chains with similar length are found out and are paired two by two; the paired chains are installed insidethe same growth box, thereby greatly reducing the length difference of the chains on the two opposite sidewalls inside the same growth box.

Description

technical field [0001] The invention relates to a plant growth box, in particular to a chain length matching device and matching method. Background technique [0002] The volume of the plant growth box is very large, and many growth tanks are arranged in the plant growth box. In order to allow the plants in the growth tanks to continuously obtain water and light, the growth tanks need to be moved constantly. The growth trough is generally driven by a chain, such as figure 1 As shown, the chain 200 is installed on the two opposite side walls of the growth box 100, and a plurality of tensioning wheels 300 are arranged on the side walls, and the chains respectively bypass all the tensioning wheels and connect end to end. A guide hook 400 is arranged at a certain distance, and the two ends of the growth groove are hung on the guide hook. When in use, the chains on the two side walls move at the same part to drive the growth trough forward. [0003] In this system, the positio...

Problems solved by technology

[0004] There are difficulties in this, one: the length of the chain on each side is very long, and the chains are all assembled parts, there are gaps between the parts, resulting in great differences between the chains, if the random installation method is adopted, there will often be inconsistencies Qualified situation

[0005] Two: When running for a long time, there will be errors in the chains on both sides, so the operation will be out of sync
