It is about a block demoulding device.

Generally, ridges are formed between rice fields, made by piling mud high up. These ridges not only serve as boundaries between rice fields, but are also used as passageways for farmers to move to their rice fields or perform agricultural work such as spraying pesticides.

However, these conventional rice field ridges constructed with mud have the problem of being easily lost due to heavy rain during the rainy season, and in order to clear farmland and mechanize cultivation, rice field ridges are formed by connecting ridge blocks made of concrete in unit lengths. It has been suggested that

As an example of such a rice field ridge block, Korean Patent Registration No. 10-1057172 (registration date August 9, 2011) includes a boundary wall installed upright in the center of the base buried underground, a walkway formed at the top of the boundary wall, and the walkway. Accordingly, a rice field ridge block is disclosed that includes tracks installed spaced apart on both sides of a walking path so that casters installed on the lower side of agricultural equipment can freely move and run in a seated state.

However, these rice field ridge blocks have an "I" shape with the lower part wider than the upper part for stability, but to prevent defects due to air bubbles being trapped inside when pouring concrete into the formwork, the upper and lower parts of the formwork are separated. It is formed to correspond to the lower and upper parts of the rice field ridge block.

Performing the work of opening the upper part of the form, demolding the cured rice field block, and reversing the rice field block to its normal position by manpower has the problem that the work efficiency is very low because the rice field block is very heavy, and there is a risk of injury to workers. A demoulding device for these concrete ridge blocks was required.
