Description

[Detailed Description of the Invention] This invention relates to a chemical liquid protection structure for a self-propelled power sprayer, also known as a speed sprayer, for an orchard disinfection machine.

In general, self-propelled power sprayers are installed in this order from the front of the machine: the driver's seat, the chemical tank, and the spraying section. Therefore, if the chemical overflows from the injection port of the chemical tank, it will spill onto the outside of the tank. It may flow to the driver's seat and hit the driver.

This proposal aims to prevent the above situation and protect drivers from extremely toxic chemicals.

The present invention will be explained below based on embodiments shown in the drawings.

A is a self-propelled power sprayer, and the driver's seat 1 is located from the front of the aircraft.
, a chemical solution tank 2, and a spraying section 3 are provided in this order.

In addition, 1' is the control part of the driver's seat 1, 1'' is the seat, 2 is the liquid injection port provided at the top of the chemical tank 2, and 2'1 is the liquid injection port 2.
' is a lid body, 3' is a spray driving part in the spraying part 3, so to speak, a blower, 4 is a spout, and the chemical liquid in the chemical liquid tank 2 is sent to this spout 4 by a jet bong provided in the driving part 3'.
From this nozzle 4, the spray is dispersed over a wide area in the form of mist by the wind from the blower 3''.

Further, reference numeral 5 denotes wheels, and in order to facilitate traveling on uneven ground, slopes, etc., eight or more wheels are used, and a track running device may be used.

Reference numeral 6 denotes a protective wall detachably installed in the chemical solution tank 2 at a position near the driver's seat 1 from the injection port 2'. It is composed of “.

The receivers 7 and 7 provided on both the left and right sides of the chemical tank 2 are made of gold. In the stationary state, a rubber band 6' is stretched from one side of the chemical tank 2 to the other side over the top of the tank 2, and serves as a protective wall 6 to protect the chemical tank 2. It will be formed in a substantially arc shape in the upper half of the .

In addition, the protective wall 6 can be placed at any position near the driver's seat 1 by forming the metal parts 7, 7 as rod-like bodies along the longitudinal direction (front-back direction) of the chemical liquid tank 2 as shown in the drawing. Furthermore, in addition to being provided at a position closer to the driver's seat 1, it is also possible to provide a protective wall from the liquid injection port 2 to the side closer to the spray section 3.

Therefore, when performing spraying work, first, the chemical liquid as a disinfectant is supplied into the chemical liquid tank 2 from the liquid injection port 2', and then while the power sprayer A is running, the chemical liquid that is the disinfectant liquid enters the nuclides of the fruit trees, etc. From step 3, the chemical solution will be dispersed in a mist.

Therefore, when supplying the above chemical solution, from the liquid injection port 2' to the driver's seat 1.
If a protective wall 6 with a rubber band 6' is constructed at the position on the closer side, the chemical solution will spill during this liquid supply, and the liquid injection port 2'
Even if the chemical liquid flows along the outer surface of the tank 2, its flow is blocked by the protective wall 6 and does not flow toward the driver's seat 1.

Also, when driving in the orchard after completing the liquid supply, if the protective wall 6 is removed from the chemical tank 2, the protruding part of the protective wall 6 will be removed, so if the liquid enters the fruit tree's nuclei, etc., this protective wall will be removed. 6 can prevent damage to fruits and trees.

Since the present invention is constructed as described above, it is possible to protect the driver from the highly toxic chemical solution even to a small extent.Also, according to the present invention, the protective wall is removable, so this protective wall can be used during spraying work. By removing it, there is a practical benefit of not damaging the fruit or the tree.
