The present invention has been devised to solve the problems of the prior art, and it effectively distributes the load of water applied to the bottom surface of the water tank, is easy to attach to and detach from the vehicle, and has excellent vibration absorption effect due to the movement of the vehicle. An object of the present invention is to provide a method of assembling a water tank and a watering vehicle for the assembly structure of the tank and the watering vehicle.

A method of assembling a water tank, a water tank, and a water spraying vehicle according to the present invention includes the steps of installing a load distribution unit and a support unit in the water tank (S100); Installing the base frame to be fixed to the chassis frame of the watering vehicle (S200); seating the water tank at a designated position on the upper side of the base frame (S300); connecting the water tank and the base frame to each other using a fastening part (S400); fixing the water tank to the base frame by tightening the fastening part (S500); and a step (S700) of sealing the watertight part by fitting the watertight lid to the watertight body so that one end of the fastening part located inside the watertight body does not come into contact with the mixed liquid inside the water tank (S700). In the water tank, a liquid mixed with water or chemicals (hereinafter referred to as “mixed liquid”) is stored therein, and the load distributing part rises convexly as it goes from both ends to the center, and the cross section at the center is the highest point. arch-shaped body; One end is integrally connected to both ends of the body in a round shape and is inclined upward toward the outside, and the other end is a pair of wings connected to the side of the water tank by resin welding; a plurality of convex portions formed to protrude convexly; and a connecting portion extending outwardly from both ends of each of the plurality of convex portions to connect the convex portions to each other, wherein the size of each of the plurality of convex portions is at the height of the space between the load distributing portion and the floor surface. It is determined correspondingly, and an upper portion of each of the plurality of convex portions is in contact with the load distribution unit in a shape corresponding to the shape of the load distribution unit, and the watertight portion is formed with an open portion on the upper side, and the lower surface is integral with the load distribution unit Watertight body connected to; and a watertight lid fitted to the upper portion of the watertight body to close the opening, thereby closing the watertight part so that the space inside the watertight part is watertight from the mixed liquid inside the water tank. At least one protrusion is provided on the upper side, and at both ends of one surface of the watertight lid facing the watertight body, at least one depression to be fitted to the protrusion in a shape corresponding to the shape of the protrusion is formed.

In addition, the watertight lid has an arcuate cross section and protrudes roundly and is convex while inclining upward from both ends to the center.

In addition, the step S100 may include connecting the load distribution unit and the support unit to each other (S110); and installing the load distribution unit to which the support unit is connected on the bottom surface of the water tank (S130), and the point at which the main body and each of the pair of wings are connected is the lowest point of the load distribution unit in step S130. As a result, in a state in contact with the bottom surface, the bottom surface and the lowest point of the load distribution part are fastened and fixed by resin welding or screws, and installed on the bottom surface of the water tank.

In addition, in step S400, each of a pair of fastening parts connecting the water tank and the base frame at both ends of the load distributing part among the plurality of the fastening parts passes through the base frame, the bottom surface, and the load distributing part in turn. In the above, one end of the body of the fastening part passes through the center of the lower surface of the watertight body and is located in the space inside the watertight part, and connects the water tank and the base frame to each other at both ends of the load distribution part among the plurality of fastening parts. Each of the other fastening parts except for the pair of fastening parts passes through the base frame, the bottom surface, the support part, and the load distribution part in turn, and then, one end of the body of the fastening part penetrates the center of the lower surface of the watertight part to the inside of the watertight part. of the plurality of fastening parts, each of the plurality of fastening parts is fixed by screwing a nut to one end of the body of the fastening part to fix the water tank to the base frame.

The method of claim 1, wherein the step S100 further comprises a step (S120) of seating a first rubber member on both ends of the bottom surface inside the water tank between the S110 and the S130 (S120). In step, each of a pair of fastening parts connecting the water tank and the base frame at both ends of the load distributing part among the plurality of fastening parts penetrates through the base frame, the bottom surface, the first rubber member, and the load distributing part in turn. Next, one end of the body of the fastening part passes through the center of the lower surface of the watertight body and is located in the space inside the watertight part, and connects the water tank and the base frame to each other at both ends of the load distribution part among the plurality of fastening parts Each of the other fastening parts except for the pair of fastening parts passes through the base frame, the bottom surface, the support part, and the load distribution part in sequence, and then, one end of the body of the fastening part penetrates the center of the lower surface of the watertight part to pass through the watertight part Located in the inner space, each of the plurality of fastening parts is fixed by screwing a nut to one end of the body of the fastening part in step S500 to fix the water tank to the base frame.

In addition, between steps S500 and S700, a step (S600) of accommodating the second rubber member inside the watertight body may be further included.

The method of assembling a water tank and a sprinkler vehicle according to the present invention can be largely divided into a step of installing a load distribution unit and a support unit in the water tank and a step of installing the water tank on the upper side of the base frame of the watering vehicle. After completing the installation of the load distributing part and the support part in advance, the water tank can be installed on the watering vehicle through the fastening unit in another space, which has the advantage of simplifying the process of assembling the water tank to the watering vehicle.

In addition, the load distribution part having a parabolic cross section and a support part having a plurality of arcuate convex parts are provided at the bottom of the water tank, so that the load is transferred to the bottom of the water tank and the bottom surface of the water tank compared to the conventional method in which the load of the water tank is concentrated at the corners. It can be evenly distributed on the base frame connected to the vehicle's chassis frame.

In addition, since the first rubber member is provided between the load distribution unit and both ends of the inner bottom surface of the water tank, vibration generated during driving can be absorbed.

In addition, since the second rubber member is provided inside the watertight body, it is possible to prevent damage to the watertight part due to the load of the water tank.

In addition, since the cross section of the watertight lid is manufactured in an arcuate shape, the load of the water tank applied to the watertight part can be dispersed, thereby preventing the watertight part from being damaged, and thus the durability of the watertight part can be improved.
