Description

{Device of Compressing and Binding Logging Residues}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a harvesting by-product compression binding apparatus, and more particularly, to a harvesting apparatus for harvesting by-products by compressing harvesting by-products into bundles.

As is well known, with the rise of global environmental problems and the growing interest in environmentally friendly energy sources, we are focusing on alternative energy development along with reduction of energy consumption through high efficiency equipment.

Therefore, it is urgent to identify and utilize the most advantageous energy source among alternative energy sources. Korea is expected to utilize forest biomass energy as alternative energy under the climate change response system based on high oil price and carbon emission reduction, and it is increasingly commercializing forest biomass energy. .

Most of the energy use of woody raw materials utilizing forest biomass was to convert solid fuel into direct energy by burning it. However, recently, it has been converted into gas or liquid type fuel through pyrolysis, fermentation, etc., Researches are being actively conducted.

However, in the case of wood-based raw materials, there has been a raw material competition for wood-based raw materials as the raw material that has been introduced to the existing wood industry has increased in energy demand due to the spread of wood pellet boilers and the like.

In order to secure additional wood-based raw materials that are lacking in this respect, bio-recycling forests will be created, waste by-products will be recycled, and wood-based energy forests will be built around the number of properties. Among them, harvesting by-products at the current timber production site is advantageous in that they can be collected on-site at the moment, unlike bio-circulation forests or wood energy forests. Especially, in the case of domestic, 9 million m3 / year is cut down and 54% of them are left in forests.

In the case of pelmis, 77% is abandoned simply because it is not economical. In order to utilize these unused forest resources for energy use, there is a growing interest in building an efficient system that can reduce harvesting costs, and there is a great expectation for improvement in environmental aspect and profitability.

In addition, in order to utilize forest biomass as an energy resource in mountain regions, it is important to estimate available forest biomass resources and to estimate the costs incurred in harvesting and transportation, and approach them from an economic point of view. In particular, harvested by-products can not be used economically if they are harvested and transported at a low density, unlike wood harvesting.

Most of the timber harvesting systems in Korea are mainly made by chain saws in the mountains, and then they are harvested and sorted in a certain size. In this case, collecting and harvesting the harvested waste by-products separately is not an economical method from a cost point of view. Even if they are collected separately, they are very difficult to be stored or treated in the field due to their too large volume by weight, and transportation and transportation costs are high in transportation.

Therefore, in order to collect by-products from the field, it is applied as a method of collecting waste materials from the inside of the building to prevent them from collecting them separately.

However, in this case, it is often costly to transport the harvested harvesting byproducts directly to the customer. Therefore, the wood crusher, which is mainly supplied to the domestic market, can enter the site but it is very inefficient to break down the by- Most of the type of crusher.

Therefore, the separate crusher of the top-loading grinder system is effective, but the work on the side of the crusher is very limited because there is not enough space to produce the crusher product. In this case, most of the work must be done in a heavy-duty workspace, and the harvesting by-products collected at the site have a disadvantage that they must be sowed from the collection site to the place where the large grinder is located. In this case, small pallet trucks or trucks are needed, but there is a limit in economically transporting waste by-products that are bulky by weight.

In 2010, 1,500 tons of wood and 670 tons of harvested by-products were produced for the pilot sites in Yeoju as a result of the production of wood and harvested by-products. The production of raw timber was 71,000 won per ton, and the by-product of shredding costs 99,000 won per ton to the customer. The cost of producing more byproducts was higher than the cost of wood production, and the transportation cost was 422,000 won out of the 99,000 won per trillion by-product production cost. Therefore, it is required to carry or transport the dense by-products at a high density because the proportion of the transportation cost increases.

Therefore, it is very difficult to recycle waste by-products as an energy source because of the cost of disposal. In the case of leaving forests in forests as in the case of forest leavings, there is a risk of spreading forest fires in the event of forest fires, and ecological disadvantages due to reduced forest area in the reforestation for renewal and costly disadvantages due to additional disposal or disposal operations. There were many cases. To solve these problems and to use the waste by-product as a substitute for the woody raw material, it is necessary to transport the waste by increasing the density of the bulky waste by-products.
