Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mixing and adjusting a greening mulch for use in parks, slopes, playgrounds and the like and a mulch for facilities such as general soil and airfields. Concerning how to do it at the same time. 2. Description of the Related Art For various purposes such as prevention of tree planting and soil erosion, and prevention of walking and slipping, multi-materials such as wood chips are scattered on the surface of soil. When using wood chips as the main material and mixing and adjusting flower seeds, fertilizers, insecticides, coloring pigments and other compounding agents according to the purpose, and spraying various mulch materials, conventionally a compounding machine and a spraying machine are used. The work was inconvenient because they were individually prepared, and the setting of the composition was not immediately and easily performed in accordance with the situation of the spraying soil and switching of the construction specifications. [0003] The present invention relates to a mixing method in which the types and proportions of a granular (solid) compounding agent and a liquid compounding material can be changed during spraying in response to the sprinkling soil and construction specifications. A method of dispersing is provided. According to the present invention, a compounding agent is supplied into a pipeline from a granular compounding agent storage hopper provided in a pipeline for transporting wood chips, mixed during transportation, and a plurality of liquids are mixed. The required compounding agents are pressurized and mixed from the compounding agent storage tank to the mixing liquid supply pipes by dedicated pumps, respectively, and the respective mixtures are supplied into the discharge spray nozzle connected to the spraying hose, and the high-speed discharge in the spraying hose is performed. This is a method in which solid-liquid agitation and mixing are caused by an air flow to spray the compounded multi-material. In the present invention, the numbers of the granular compounding agent and the liquid compounding agent are not limited, and the numbers of the granular compounding agent storing hopper and the liquid compound storing tank are also arbitrary. [0005] The method of the present invention is carried out by the apparatus shown in the drawings. In the figure, 1 is a compressor (pressure 0.6)
^{Kg / cm 2 G~1.5Kg / cm 2} G), 2 is the carrier tube (diameter of about 10~16cm), 3 is a chip accommodating chamber, 4 can also be a discharge rotor comprises a cutter. 5
A and 5B are seeds, hoppers of granular compounding agents such as granular fertilizers,
Reference numeral 6 denotes the discharge rotor, which is connected to each of the transport pipes. 7 is a mixed discharge spray nozzle, 8 is a hose coupler, 9 is a discharge spray hose of several tens to 200 m (diameter 8).
１２12 cm). 10A, 10B, 10C, 10D
Are tanks for individually storing liquid compounding agents such as water, liquid insecticide, or flame retardant, and each dedicated pump 11A,
11D are connected to the mixing liquid supply pipe 14, and the mixing liquid supply pipe is connected to the liquid supply port 15 of the injection nozzle. The structure of the injection nozzle is not particularly limited, but for example, a nozzle as shown in FIG. 2 can be used. The chip material, seeds and other solid compounding agents are discharged in a predetermined set amount to the conveying pipe, and are introduced into the nozzle chamber 20 while being mixed and are stirred. The liquid agent is sent out from the pump at a predetermined pressure, is partially mixed while flowing through the mixing liquid supply pipe, and is injected into the nozzle chamber 20 from one or more liquid atomizing nozzles 21. The solid compounding agent adheres to the chip surface while passing through the liquid material curtain 22, and as a result, the chip material is sent out into the hose as a wetting material to which both the solid and liquid compounding agents have adhered. Furthermore, since the inside of the hose is agitated in the tube by a high-speed airflow, mulching can be performed with substantially equal mixing even if the bulk density of the individual compounding agent or the specific gravity of the liquid agent is different. [0007] The multi-chip material is prepared as shown in FIG. That is, the felled timber is turned into chips by a crusher and
It is sorted by a mm mesh, and an oversized one is used as a multi-material, and an undersized one is used as a compost material. Examples of the use of the multi-chip material are shown in FIGS. 4 to 6, and as the granular compounding agent,
Since seeds such as turf, fertilizers and insecticides are required, hoppers 5A and 5B are prepared in such a number. Liquid compounding agents include water, water-based coloring pigments, liquid manure, water-soluble insecticides, liquid flame retardants, and the like. Each requires a dedicated tank, but pesticides that require a small amount of liquid are shown in FIG. For example, by providing the switching valves 12C and 12D and the connecting pipe 13, the pump 11D can be saved. In the case of the greening mulch shown in FIG. 6, it is necessary to previously mix composted chips with soil, sand, and the like. When the mixing ratio of the multi-material is changed, the number of revolutions of the discharge rotor 6 or the pump 11A may be adjusted, and when changing the compound type of the multi-material, the discharge rotor 6 may be changed.
Alternatively, it can be dealt with simply by opening and closing the pump 11A and the like. The apparatus of the above embodiment can be mounted on a large self-propelled vehicle, or installed only on a solid transportation system in a large vehicle, and mounted on a towing vehicle with a tank system to improve mobility. In addition, since the hose length can be set to 200 m or more, mulching in a forest or a slope where vehicles cannot enter can be performed, and greening mulching or color mulching in a large construction site such as an airfield or a park can be performed in a short time.
