Description

[Detailed description of the invention] [Industrial application field] This invention relates to a self-propelled boom sprayer for disinfecting agricultural products such as fields.

[Conventional technology]

Conventional boom sprayers have performed pest control operations by being mounted on a tractor or being towed.

[Problems that the idea should solve]

These operations involve difficulties in attaching, dismounting, and mounting large tanks, and in practice they take a considerable amount of time.

[Means for solving problems]

This invention solves these problems, and consists of a raised floor type vehicle having a front wheel and a rear wheel, which is larger in diameter and width than the front wheel, mounted on both side edges, and has a ground clearance that is at least larger than the diameter of the front wheel. This is a dedicated trolley, on which the driving engine, pump, etc., driving and working parts, and the control device are installed on the front part of the dedicated trolley, the drug tank is mounted on the center part, and the rear side edge is foldable. The present invention provides a self-propelled boom sprayer that is equipped with a boom device that expands outward.

[Effect]

Next, this idea will be explained with reference to the drawings.

A front wheel 1 and a rear wheel 2 having a larger diameter and width than the front wheel 1 are mounted on both side edges, respectively, and are mounted on the front part of a dedicated raised platform truck 3 having a ground clearance larger than the diameter of the front wheel 1. driving engine,
A driving and working part 4 for a pump etc. and a control device 5 are installed, a drug tank 6 is mounted in the center, and a boom device (long It has a structure in which a spraying device (spraying device) 7 using a spray pipe is disposed, and the boom device 7 sprays the disinfectant onto agricultural crops such as fields while the dedicated trolley 3 is traveling.

[Effect of idea]

This invention produces the following effects. In other words, 1. Since the rear wheel 2 is installed with a larger diameter and width than the front wheel 1, the boom device 7, which is a long spray pipe, can be removed even if the ground is uneven when traveling between the furrows of the field. Even if it is expanded to both wings, safe running spraying is possible.

2 Since it has a special raised platform trolley 3 with a ground clearance larger than the diameter of the front wheels 1, it is possible to reduce the risk of growing crops coming into contact with the floor of the trolley 3 and damage them, and it is possible to prevent running spraying across ridges or crops. It becomes possible.

3 Since the drug tank 6 is mounted in the center,
It is easy to balance the load on the wheels front to back, left and right, and it is possible to load large capacity drug tanks.

4. Since the boom device 7 is disposed on both sides of the rear side, the chemicals to be sprayed are sprayed to the rear of the trolley 3, making it possible to reduce the exposure of the operator due to floating chemicals.
