If the homestead be conveyed by the claimant, or sold for the satisfaction of any lien mentioned in section 40-103, the proceeds of such sale, beyond the amount necessary to the satisfaction of such lien, and not exceeding the amount of the homestead exemption, shall be entitled, for the period of six months thereafter, to the same protection against legal process and the voluntary disposition of the claimant which the law gives to the homestead. The sale and disposition of one homestead shall not be held to prevent the selection or purchase of another, as provided in sections 40-101 to 40-116.
