Description

[Detailed Description of the Invention] This invention relates to a chemical liquid protection device whose purpose is to protect the driver of a chemical spraying vehicle that sprays a chemical while traveling in a field from the sprayed chemical liquid.

Conventional chemical liquid protection devices of this type come in two types: a box type that completely covers the driver, and an air curtain type. It is necessary to equip auxiliary means such as a device, which causes the disadvantage of being expensive, and since the driving part protrudes into a box shape, it is easy to hit trees and the like, causing damage to the trees and the like. In addition, the latter type, that is, the air curtain type, is not very effective because the sprayed chemical solution is sucked in by the air curtain blower, and there are inconveniences such as the need to install a filter or other means to prevent this. It was hot.

This idea was made in view of the above circumstances,
By comprising a foldable skeleton and a flexible protective canopy attached to the top of this skeleton,
It is extended into a shape to protect the driver as needed, protecting the driver from chemical solutions, and the skeleton can be deformed so that it can be folded even if it comes into contact with an obstacle such as a tree in the field. Therefore, it is an object of the present invention to provide a chemical liquid protection device for a chemical spraying vehicle that does not damage trees or the like, does not reduce visibility, and can be manufactured at low cost.

Examples of this invention will be described below based on the drawings.

Figures 1 and 2 show a front view and a side view of the chemical spraying vehicle equipped with the chemical liquid protection device of this invention in use. A chemical liquid tank 3 and a chemical spraying nozzle 4 are equipped at the rear of the chemical liquid tank 2, and the chemical in the chemical liquid tank 3 is sprayed radially outward from the chemical spraying nozzle 4 by a pump (not shown). ing. In this case, the chemical liquid protection device 5 of this invention is installed so as to protect the driver of the driving section 2, that is, the worker A, from the sprayed chemical liquid.

The chemical liquid protection device 5 includes a pair of base frames 6 that protrude upward from the rear of the seat of the driver section 2;
6, a swinging link 8 which is pivotally attached to the intermediate part of each base frame 6 with a pivot pin 7 and protrudes toward the driver side, and a pivot link 8 with a pivot pin 9 at the tip of the swing link 8. A skeleton part 13 is constituted by a support link 10 that is attached to the base frame 6, and a connecting link 12 that is installed with pivot pins 11, 11 above the pivot part of the swing link 8 in the base frame 6 and on the support link 10, respectively. A flexible protective canopy 14 is attached to the upper part of the base frame 6 and the tip of the support link 10 in this skeleton part 13 which is foldably deformed by the swing link 8 and the connecting link 12. , as shown in FIGS. 3 and 4, when in use, the swing link 8 and the support link 10 are straight with respect to the base frame 6 and protrude obliquely upward, so that the protective hood 14
The worker A is protected from the chemical solution when the
By displacing parallel to the base frame 6
The support link 10 can be folded parallel to and close to the support link 10.

As explained above, the chemical liquid protection device of this invention is composed of a foldable skeleton and a flexible protective canopy, so it can be used in the field as well as outside the field in a folded state when not in use. When in use, it protects the driver from sprayed chemicals without impairing the driver's visibility, and even if the driver comes into contact with an obstacle such as a tree, it can be easily removed. Since it is foldable, it will not damage trees, etc. or damage this protective device. Moreover, since it can be manufactured at a lower cost than conventional devices of this type, its utility value is significant.
