Abstract

PROBLEM TO BE SOLVED: To crush and treat branches and trunks into substances to be usable as compost in a short time by cutting thick branches, trunks, and cut trees by a roughly crushing apparatus while crushing the xylem parts and crushing the resultant substances into finely granular state by a finely crushing and granulating apparatus at the time of crushing treatment of branches and trunks generated by pruning trees. SOLUTION: At the time of finely crushing living leaves-bearing branches and trunks generated by pruning trees, a crusher 2 which can finely crush leaves and trunks and branches and not only cuts the trunks and branches but also crushes them while pressing them is used. The obtained crushed substances are accumulated and their surface is covered by laying water sprinkling tube to keep proper water content, prevent diffusion of heat generated by fermentation, and accelerate activation of activity of microbes. The substances are kept in that state for approximately ten days and stirred at proper timing by a turning over apparatus, and in the case the leave parts are found fermented, the resultant substances are sieved by a sieving apparatus, fine substances which drop through the sieving apparatus are turned back to the soil as soil improving materials and rough substances which are left on the sieve are finely pulverized into powder by a compressing pulverizer and fermented again.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for composting branches and leaves that occur during pruning of trunk branches and leaves such as street trees and park trees.

[0002]

2. Description of the Related Art Branches and leaves generated during pruning of trunk branches and leaves are usually incinerated at an incinerator, but they are partially pulverized and composted for soil reduction. Where the method of sedimentation fermentation is used, it is crushed with a chipper etc., accumulated as it is, and after a few months with stirring, when secondary fermentation does not occur in the soil, it becomes compost. in use.

[0003]

Therefore, at the time when decomposition can be achieved by finely pulverizing the leaf portion and the trunk branch which are easily fermented,
This part needs to be separated and taken out, and the remaining one needs to be further processed.

[0004]

[Means for Solving the Problems]

(1) Decomposition of organic matter is carried out by the activity of microorganisms, but the surface of the branches and leaves is protected by a substance that inhibits the activity of microorganisms by a natural phenomenon, so the material is crushed as finely as possible. (2) While adjusting the water content to 70-80%, 1.5
Stack up to ~ 2 meters. (3) Fermented by accumulation, the temperature rises and the wind removes water, so that the surface is prevented from drying and the temperature is used to promote microbial activity. cover. (4) The stirring is repeated once or twice a month, and after one and a half to two months, the stirring is carried out by an air dumping type turning machine. This is 5
It can be used as a soil conditioner by sieving with a mesh of about 6 mm and dropping it under the sieve. The residue left on the sieve is re-fermented into fine powder with a compression grinder and returned to the soil.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION

(1) Use a crusher that can finely crush both leaves and trunk branches, and not only cut the trunk branches but also crush them while crushing. (2) Crushed stems and leaves are accumulated, and a sprinkling tube is laid to cover the surface with a sheet to prevent the retention and drying of suitable water and prevent the dissipation of heat generated by fermentation, thus activating microbial activity. Promote conversion. (3) After about 10 days, stir with a compost turning device. (4) If it is confirmed that the leaves are fermented and decomposed, they are sieved with a sieving machine and the fine particles that fall are returned to the soil as an improving material. (5) The rough material remaining on the sieve is made into a fine powder with a compression crusher, returned to the pile of piled compost and re-fermented. Since this fine powder is made of the trunk branches in the middle of fermentation and contains the fermenting bacteria that are also growing, the effect of promoting fermentation can be expected.

[0006]

EFFECTS OF THE INVENTION According to the above method of the present invention, a fine-grained piece from a stem-and-leaf mixed material generated at the time of felling trees and pruning stems and leaves, having a diameter of about 15 cm to an extremely thin branch with leaves It can be crushed into pieces and crushed to a state where it can be used as compost or the like within a short period of time.
