Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are denoted by the same reference numerals, and overlapping descriptions are omitted.

[System configuration]
A weeding system 1 according to an embodiment is a system for spraying a weeding liquid to a desired location. FIG. 1 is a diagram showing an example of a weeding system 1. As shown in FIG. In this example, the weeding system 1 includes an agitator vehicle 10 that provides a weeding liquid 40, a relay tank 20 that stores the weeding liquid 40 discharged from the agitator vehicle 10, and a spraying tank that sprays the weeding liquid 40 in the relay tank 20. machine 30; A user of the weeding system 1, i.e., an operator, travels to a weeding site with the agitator vehicle 10, installs the relay tank 20 to receive the weeding liquid 40 from the agitator vehicle 10, and sprays the weeding liquid 40 using a sprayer.

The agitator vehicle 10 has a drum 11 for producing the weeding liquid 40, a hopper 12 for receiving the raw material of the weeding liquid 40, a chute 13 for discharging the weeding liquid 40 to the outside, and washing these parts. It is a self-propelled vehicle provided with a water tank 14 that stores water for water. The term “agitator vehicle” in the present disclosure refers to a vehicle equipped with a drum having an agitating function, and in one example, means a concept that includes both generally-called agitator vehicles and mixer vehicles. The drum 11 is a large tank with a stirring function, and can rotate in both forward and reverse directions. The hopper 12 is an inlet that communicates with the rear end of the drum 11 . The chute 13 is a channel provided below the hopper 12 . It should be noted that the water tank 14 is used to store washing water, not to store herbicide solution 40 .

The dimensions of the agitator wheel 10 may be selected in consideration of the amount of herbicide 40 . An agitator wheel with a drum 11 capacity of 1 m ³ to 10 m ³ may be used. For example, a small vehicle with a capacity of 2 ^m3 may be used, a large vehicle with a capacity of 6 ^m3 may be used, or an even larger vehicle with a capacity of 10 ^m3 may be used. good too. In one example, an agitator vehicle for generating or transporting ready-mixed concrete may function as the agitator vehicle 10 to generate and transport the herbicide liquid 40 as needed.

The relay tank 20 is a tank that temporarily stores the weeding liquid 40 discharged from the drum 11 . The relay tank 20 has a bottom surface and side surfaces, but does not have a top surface covering the bottom surface. Therefore, the entire upper portion of the relay tank 20 forms an opening. Although the relay tank 20 has a cylindrical shape in the example of FIG. 1, the relay tank 20 may have another shape such as a prismatic shape. The capacity of the relay tank 20 may be 0.1 m ³ to 3 m ³ or 1 m ³ to 3 m ³ . In one example, the relay tank 20 may be foldable, for example, a foldable tank formed using a resin sheet such as a plastic sheet. A discharge port 21 for discharging the herbicide 40 is provided near the bottom surface of the relay tank 20 . Through the discharge port 21, the residual liquid that has not been sucked up by the pump can be easily discharged, and the relay tank 20 can be efficiently washed.

The sprayer 30 is a device for spraying the weeding liquid 40 in the relay tank 20 to plants to be weeded. In one example, the sprayer 30 includes a pump 31 that sucks up the weeding liquid 40 in the relay tank 20, a hose 32 that passes the sucked weeding liquid 40, and a nozzle 33 that discharges the weeding liquid 40 to the outside. The pump 31 is driven by power obtained from energy such as electricity or gasoline, and supplies the weeding liquid 40 to the nozzle 33 . The discharge amount of the sprayer 30, that is, the amount of the herbicide 40 discharged from the nozzle 33 may be 20 L/min or more, or may be 40 L/min or more. One end of the hose 32 is connected to the pump 31 and the other end of the hose 32 is connected to the nozzle 33 to form a flow path from the pump 31 to the nozzle 33 . The length of hose 32 may be, for example, 5m or longer, 10m or longer, or 30m or longer. The inner diameter of the hose 32 may be 10-50 mm, or may be 15-40 mm. The nozzle 33 may have a structure for switching the injection method. For example, by turning the tip of the nozzle 33 , it may be possible to switch between direct injection and spraying, or the switching may be performed by a switch provided on the nozzle 33 .

Water and herbicide, which are raw materials of the herbicide, are put into the hopper 12 and flow into the drum 11 . In one example, forward rotation of drum 11 agitates and mixes the water and herbicide to produce herbicide solution 40 . In one example, the drum 11 rotates in the opposite direction so that the weed killer liquid 40 is discharged from the drum 11 through the chute 13 . The weeding liquid 40 discharged from the drum 11 is temporarily stored in the relay tank 20 . A pump 31 is placed in the relay tank 20 . By operating the pump 31 and operating the nozzle 33 , the weeding liquid 40 in the relay tank 20 reaches the nozzle 33 via the hose 32 from the pump 31 and is discharged to the outside from the tip of the nozzle 33 .

[How to use the system]
The user prepares the agitator vehicle 10, the relay tank 20, the sprayer 30, and the herbicide. A user puts water into the drum 11 from the hopper 12 . The user drives the agitator vehicle 10 and goes to the weeding site. The user may load the relay tank 20 and the applicator 30 on the agitator vehicle 10 and head to the weeding site, or may transport the relay tank 20 and the applicator 30 to the weeding site by a vehicle other than the agitator vehicle 10. . The user further puts a predetermined amount of herbicide into the drum 11 from the hopper 12 and rotates the drum 11 forward. This operation agitates the water and herbicide in the drum 11 to produce the herbicide solution 40 . The user may generate the weeding liquid 40 before heading to the weeding site or after arriving at the weeding site.

The user installs the relay tank 20 under the tip of the chute 13 . Since the entire upper portion of the relay tank 20 is open, the user can flexibly set the positional relationship between the chute 13 and the relay tank 20 as long as the tip of the chute 13 is positioned within the opening of the relay tank 20 . The user reversely rotates the drum 11 , and this operation causes the weeding liquid 40 to be discharged from the chute 13 and stored in the relay tank 20 . The user puts the pump 31 into the relay tank 20 and activates the pump 31 . The user moves the nozzle 33 to a desired location while extending the hose 32 and operates the nozzle 33 to spray the weeding liquid 40 . The user may switch the ejection pattern of the nozzles 33 as needed. The amount of herbicide may be 5 L to 50 L or 10 L to 40 L per 1 m ³ of water. The application amount of the herbicide 40 may be 0.05 to 5 L per 1 m ² or may be 0.1 to 3 L per 1 m ² .

Herbicides refer to agents for eliminating specific plants. Examples of herbicides include non-selective herbicides, selective herbicides, bio-herbicides, hydrogen peroxide, and ozonated water. A non-selective herbicide has, for example, glyphosate as a main component, and inhibits the shikimic acid synthesis pathway (EPSPS inhibition), thereby exhibiting herbicidal effects regardless of the type of plant. Selective herbicides kill broadleaf weeds other than turf by disrupting the hormonal balance using synthetic hormones that are less effective on, for example, grasses. Examples of selective herbicides include phenoxys (MCPP). Selective herbicides may be foliar or stem absorbed to be effective. In this case, unlike herbicides that are absorbed through the roots, only weeds around the trees can be killed without killing tall trees. Bioherbicides are biobased herbicides made from specific microorganisms or insects. Bioherbicides are environmentally friendly and cost less than conventional herbicides. Bioherbicides have less adverse effects on crops and human health than conventional herbicides.

A weeding system according to the present disclosure may be defined as follows.
(Item 1)
an agitator vehicle equipped with a drum that produces a herbicide by means of an agitating function;
a relay tank containing the weeding liquid discharged from the drum;
a sprayer for spraying the herbicide in the relay tank;

Weeding system according to any one of items 1 to 6.

According to item 1, the weeding liquid produced in the drum of the agitator vehicle is temporarily transferred to the relay tank, and the weeding liquid in the relay tank is sprayed by the sprayer. By combining an agitator vehicle, a relay tank, and a sprayer in spraying the herbicide, the herbicide can be sprayed even in places where vehicles cannot enter. As a result, the application range of the herbicide can be expanded. For example, weeding work can be carried out in various places related to civil engineering, construction, and agriculture, even if there is no water source nearby. In addition, since the weeding liquid is generated by the agitation function of the drum, the labor required for preparing the weeding liquid can be reduced, and the weeding liquid can be easily sprayed by using the relay tank and the sprayer. Therefore, it becomes possible to realize labor saving and rationalization of large-scale weeding work.

It is conceivable to suck up the herbicide directly from the pump inserted in the drum of the agitator vehicle without using the relay tank, but in this case, the efficiency of the spraying work cannot be realized. Also, rotating the drum with the pump in it can damage the drum or the pump.

According to item 2, since the upper part of the relay tank that receives the weeding liquid discharged from the drum is not covered, the relay tank can be easily positioned with respect to the agitator vehicle. For example, the relay tank can be easily positioned with respect to the tip of the chute of the agitator car.

According to Item 3, a lightweight and foldable relay tank is provided, so that the relay tank can be easily carried. For example, the relay tank can be loaded and transported on an agitator car.

According to item 4, the agitator vehicle and the relay tank are provided according to the expected required amount of weeding liquid, so that the convenience of the weeding system can be improved.

According to item 5, the length of the hose is 5 m or more, so the herbicide can be sprayed even in areas relatively distant from the agitator vehicle and the relay tank. Therefore, the herbicide can be sprayed more flexibly in various places.

According to item 6, since the discharge amount of the sprayer is high, it is possible to spread the weeding liquid more easily over a wide area.

According to item 7, an agitator truck carrying ready-mixed concrete is used for the weeding system. Thus, for example, ready-mixed concrete contractors can be provided with the opportunity to use agitator vehicles for weeding services. The ready-mixed concrete supplier will be able to run his agitator truck more efficiently, or run a weeding service as a side business to generate more sales.

Examples will be specifically described below, but the present disclosure is not limited to them.

Using the weeding system corresponding to the above embodiment, three types of slopes with areas of 1000 m ² , 2000 m ² and 5000 m ² were weeded as Examples 1 to 3, respectively. In these examples, the drum of the agitator vehicle contained the water and was transported to the weeding site. At the weeding site, the glyphosate-based herbicide was put into the drum of an agitator vehicle at a rate of 30 L per 1 m ³ of water, and the drum was agitated to form a herbicide solution. After that, the weeding solution is transferred to a relay tank, and the weeding solution is applied to the slope at a rate of 1 L per 1 m ² with a sprayer having a discharge rate of 20 L / min, a hose inner diameter of 25 mm, and a hose length of 5 m. was sprayed. The nozzle used was one capable of switching between direct injection and spraying, and capable of ejecting the herbicidal liquid up to 3 m from the ejection port. In Examples 1 and 2, an agitator wheel with a drum capacity of 2 m ³ was used, and in Example 3, an agitator wheel with a drum capacity of 6 m ³ was used.

As comparative examples, a weeding operation using a mower (conventional method 1) and a weeding operation (conventional method 2) in which a weeding liquid is sprayed using a backpack type small sprinkler with a capacity of 20 L were performed. Both conventional methods 1 and 2 were performed on three types of slopes with areas of 1000 m ² , 2000 m ² and 5000 m ² . In conventional method 2, glyphosate-based herbicide was added to 1 m ³ of water at a rate of 30 L, and the herbicide was sprayed at a rate of 1 L per 1 m ² in the same manner as in Examples.

Table 1 shows the man-hours (man-days) required for weeding and the weeding effect (period) representing the duration of the effect of the herbicide in each example and each comparative example. As can be seen from Table 1, the examples exhibited a high herbicidal effect while significantly reducing the number of steps compared to any of the comparative examples.

[Modification]
The present disclosure has been described in detail above based on its embodiments. However, the present disclosure is not limited to the above embodiments. Various modifications can be made to the present disclosure without departing from the gist thereof.

FIG. 2 is a diagram showing a modification of the weeding system. In this example, the relay tank 50 temporarily stores the weeding liquid discharged from the drum of the agitator vehicle, and the sprayer 60 sprays the weeding liquid in the relay tank 50 . The relay tank 50 has a bottom surface, a side surface, and a top surface, and has an openable/closable lid substantially in the center of the top surface. The weeding liquid discharged from the drum of the agitator wheel flows into the relay tank 50 through the opening exposed when the lid is opened. Similar to the relay tank 20, a discharge port 51 for discharging the remaining herbicide is provided near the bottom surface of the relay tank 50. As shown in FIG. The relay tank 50 may be made of resin such as plastic. The sprayer 60 includes a pump 61 for sucking up the weeding liquid in the relay tank 50, a hose 62 for passing the sucked weeding liquid, and a nozzle 63 for discharging the weeding liquid to the outside. The discharge rate of spreader 60 may be selected similarly to spreader 30 . The length of hose 62 may be selected similarly to hose 32 . The nozzle 63, like the nozzle 33, may have a structure for switching the injection method.

Although in the above examples the herbicide is produced in the drum of the agitator vehicle, the herbicide may also be produced in the relay tank. In this example, the user agitates the water and herbicide in the relay tank either by himself or with an agitator to produce the herbicide solution. In this case, water is loaded in the drum of the agitator car and transferred from the drum to the relay tank.
