Abstract

PURPOSE:To enhance running stability at the time of running on a road and to facilitate the storing and keeping in a storehouse by allowing booms to approach the lateral parts of a machine body to make it possible to store and hold the machine body in such a state that the heights of the booms are suppressed low on the leading end side thereof. CONSTITUTION:Booms 11 equipped with chemical solution jet orifices 12 are provided so as to extend in left and right lateral directions and constituted so as to be revolved up and down around axial cores 25 in a before and behind direction to be made holdable to a machine frame 16 in a folded state. Further, the booms 11 are constituted so as to be revolved around lateral shafts 24 in a left and right direction to be allowed to approach the lateral parts of a machine body to be made receivable in and holdable to a machine frame 17. As a result, the center of gravity of the machine body is lowered as a whole and running stability at the time of running on a road is enhanced and the machine body can be easily stored and held in a storehouse.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a chemical liquid filtration system suitable for river field management work. [Prior art] Conventionally, this divine chemical spraying device has a chemical tank mounted on the rear of the self-propelled vehicle body, and a boom for spouting chemical liquid at the front of the machine, and this boom is moved widely to the left and right of the machine during work. The boom is extended and supported, and the chemical liquid is sprayed on crops etc. from the chemical liquid spout provided on the boom, and the movable u5 is rotated around the axis in the front and rear direction and is propped up against the support provided on the aircraft body. It was common for the device to be stored and held. [Problems to be Solved by the Invention] However, when this type of conventional device is driven on the road after finishing work, the boom is supported by a vertically erected bear; There was a problem with running stability, and the tip of this boom got caught on the ceiling of the station and got in the way when storing it in the station RA5.

[? Means for Solving Problem A] This invention was devised by Tsutsumi in view of the problems described in Section 111f, and the following technical measures were taken. That is, in a chemical liquid spraying device in which a boom l1 equipped with a chemical liquid jet 11 is extended in the lateral direction of the left stone, the boom 11 is connected to i;
iMove the machine frame up and down to the axis 25, 25 in the rear direction.
6, 16, the boom 11 is rotated around the horizontal axis 24, 24 in the left and right direction, brought close to the lateral side of the aircraft, and stored and held in the aircraft frames 17, 17. The present invention has a structure of a chemical liquid dispersion device characterized by being constructed in a convenient manner. [Example] Hereinafter, an example of the present invention will be described based on the drawings. First, to explain the configuration, 1 is a self-propelled power vehicle that has an engine 2 and a transmission case 3 that houses a transmission that decelerates the TU1 rolling force of this engine 2 at the front of the body. The transmission is transmitted to the front wheels 5 and 5 and the rear wheels 6 and 6, so that the vehicle can run in four-wheel drive. A tank 8 containing a chemical solution is provided at the rear of the aircraft, and a seat 9 is fixed to the top of this tank. The chemical liquid in the chemical liquid tank 8 is sent out by the pump 10 to the spout L412 side of the boom 11, which will be described later. The pump 10 is driven by a PTO shaft 15 that extends rearward from the mission case 3, and is configured so that the chemical solution is spouted from the spout 12 while the pump 10 is rotating. Reference numerals 16 and 16 designate first support frames erected at the front of the fuselage, and 17 and 17 designate second support frames erected on both left and right sides of the fuselage. Both support frames 16 and 17 are provided above with U-shaped receivers 18 and 19 that are open on one side, so that the boom 11 can be placed against them. 20,

! The boom 11 held by 1f can slide laterally over an appropriate range. Next, to explain the detailed structure of the boom 11, the boom 11 is divided into three parts, with the center boom 11a approximately matching the width of the aircraft, and the booms llb and llb connected to the left and right sides of the boom 11a being longer than the center boom lla. It has a long structure.

In addition, the left and right booms llb and 1lb are supported at their inner ends so as to be able to rotate freely around the fulcrum pins 25 and 25 in the front and back direction, and the tip sides can be moved I+11 towards the rear to maintain the stored state, or to touch the ground. It can be supported in a horizontally extending form that is almost parallel. Boom llb. ll

When the pin 33, 33 is pulled out forward while resisting the springs 34, 34 and inserted into one of the locking holes 35 provided on the outer periphery of the cylindrical shaft portions 24, 24, its movement is locked. In the figure, reference numeral 39 is a hose communicating with the chemical tank 8, and 40 is a control handle. In the above example, when performing chemical spraying work, the boom 11 is held horizontally parallel to the ground, the pump 10 is driven to suck up the chemical from the tank 8, and it is squirted from the spouts 1, 2, and so on. ．． When the work is temporarily interrupted in the II site and the boom 11 is stored, the fulcrum bins 25, 25 j

Pull it out from 35, rotate the cylindrical shaft parts 24, 24 inserted into the round pipes 21, 21 of the central boom lla, keep it in the width state, and tilt the left and right booms llb, llb backward. The intermediate portions are held by the receiving portions 19, 19 of the second support frames 17, 17. Figure 1 shows boom Ilb, 1lb
This shows how the booms are stored, and the height of both ends of booms llb and llb is low, and the booms are supported close to both sides of the fuselage, so the overall center of gravity is high. This not only improves driving stability but also makes it easier to store the vehicle in a barn. [Effects of the Invention] Since the present invention is constructed as described above, the boom 11 can be stored and held close to the sides of the fuselage while keeping the sharpness of the tip side low, thereby lowering the center of gravity of the entire fuselage. It has the characteristics that the vehicle's stability is lowered, improving driving stability when driving on the road, and that it can be easily delivered and stored in warehouses, etc.
