Description

  The present invention relates to a liquid agent spraying device for heavy machinery used for production of compost or the like.

  With the recent large-scale agriculture, the amount of livestock excrement is increasing. Inappropriate treatment such as unloading will cause pollution such as odor and groundwater contamination. On the other hand, livestock excrement is a cause of pollution, and is an excellent biomass resource as a fertilizer and soil conditioner if composted.

  In composting, in addition to animal waste, straw, chaff, bark, and other animal and plant matter organic matter are deposited, stirred, and ripened. Since fermentation for composting requires a certain amount of moisture and oxygen, agitation is important for producing compost of uniform quality. Moreover, by stirring the compost, microorganisms can be activated to promote decomposition and to increase the temperature.

  The organic matter accumulates in the compost house and is stirred there by turning it over. However, in a scale of a certain level or more, a stirring process is performed using a heavy machine (see Patent Document 1). At this time, if a chemical that promotes the composting process, such as a fermentation accelerator, is sprayed, the period until ripeness can be shortened and the quality is improved.

  When producing compost using a fermentation accelerator, it is efficient to perform the operation of spraying the fermentation accelerator and the operation of stirring the compost raw material at the same time. That is, when spraying with stirring, the fermentation accelerator can be mixed evenly into the entire compost raw material.

  However, when agitation is performed using a heavy machine such as a wheel loader, a worker who operates the heavy machine and a worker who sprays the fermentation accelerator are necessary. I can't do it.

  Accordingly, an object of the present invention is to provide a liquid agent spraying device for heavy machinery that allows a single operator to operate the heavy machinery and simultaneously spray the liquid agent.

  In order to solve the above-mentioned problems, a liquid agent spraying device for heavy machinery according to the present invention is a liquid material spraying device for mounting on a heavy machine equipped with a bucket, a liquid agent tank for storing the liquid agent, and a spraying nozzle unit attached to the bucket And a pipe connecting the liquid agent tank and the spray nozzle unit, and transport control means for transporting the liquid agent accommodated in the liquid agent tank through the pipe to the spray nozzle unit.

  By adopting such a configuration, it is possible to spray the liquid agent simultaneously with the operation of the heavy machinery, for example, when the agitation process at the time of composting is performed by the heavy machinery.

  In a preferred embodiment, the solution is an agent that facilitates the composting process. Thereby, the efficiency of composting work can be improved. For example, fulvic acid can be used as the solution. Fulvic acid not only shortens the period required for fermentation, but also has the effect of suppressing odors that are unavoidable during the composting process.

  In a preferred embodiment, a wheel loader can be used as a heavy machine equipped with the bucket. In addition, general heavy machinery such as a back fork can also be used.

  Further, as the transport control means, for example, a pump can be used. As an inexpensive mounting without using a pump, the liquid agent tank may be provided at a position higher than the spray nozzle unit, and a valve provided in the middle of the pipe may be used as the transport control means.

  In the heavy machine equipped with the liquid agent spraying device according to the present invention, the driver of the present invention can simultaneously perform the operation and operation of the heavy machine and simultaneously spray the liquid agent, and the working efficiency is remarkably improved.

  Hereinafter, a liquid agent spraying device according to an embodiment of the present invention will be described with reference to the drawings. Here, an example using a wheel loader as a heavy machine is shown.

  FIG. 1 is an overall view of a wheel loader equipped with a liquid agent spraying device according to Embodiment 1 of the present invention. The wheel loader includes a vehicle body 11, a boom 12 attached to the front of the vehicle body, a bucket 13 attached to the tip of the boom 12, and four wheels that rotate while supporting the vehicle body 11 and run the vehicle body. A tire 14, a cab 15 mounted on the upper portion of the vehicle body 11, and a link mechanism 16 that drives the boom 12 and the bucket 13 are provided.

  FIG. 2 is an enlarged view of a main part including the bucket 13. The liquid agent spraying device includes a spray nozzle unit 21 provided at an upper portion of a bucket 13, a liquid agent tank 22 that stores the liquid agent, a pump 23 that sucks and transports a medicine in the liquid agent tank 22, a spray nozzle unit 21 and a pump. And a pipe 24 for connecting the two.

  As shown in FIG. 2, the spray nozzle unit 21 is a rod-like member that is detachably fixed to the upper edge of the bucket 13, and the three spray nozzles 21 a, 21 b, and 21 c are evenly arranged in the length direction. Has been. The medicine inside the liquid tank 22 is pumped to the spray nozzle unit 21 by an electric drive device (not shown) inside the pump 23 and sprayed from the spray nozzles 21 a, 21 b, 21 c into the bucket 13 in the form of a mist. The driver of the wheel loader controls the electric drive unit by operating the controller 25 connected to the electric drive unit with the cable 25, and freely sprays the medicine from the spray nozzles 21a, 21b, 21c. I can do it.

  A typical application example of the liquid spraying apparatus is a stirring process in composting. A wheel loader equipped with this liquid agent spraying device is used as a heavy machine used in the stirring process. Conventionally, stirring and chemical spraying have been performed as separate operations, but if a wheel loader equipped with the liquid spraying device of the present invention is used, stirring and chemical spraying in composting can be performed simultaneously by one wheel loader driver. Can be done.

  That is, the liquid agent tank 22 stores a chemical that accelerates the composting process. Then, the bucket 13 is operated to agitate organic matter such as livestock excrement as a compost raw material deposited in the compost house. At the same time, the chemical is sprayed from the spray nozzle unit 21 to the compost raw material inside the bucket 13 as appropriate. The timing and amount are adjusted by the operator operating the wheel loader while observing the state of the compost raw material. By doing in this way, a chemical | medical agent can be mixed in an organic substance equally.
