である。 Conventionally, backpack-type power sprayers are designed to be worn on the back by placing a belt on the backrest, but the back of the sprayer itself is not very high, and in order for the operator to carry it on his/her back, he/she must first crouch down and then put the belt over his/her shoulders, which places a strain on the lower back when standing up from that position, causing lower back pain, etc. Also, if the sprayer body is placed on a high support stand, it is convenient because there is no need to crouch down, but in this position, it is difficult to perform tasks such as refilling the sprayer body with chemicals,
Even if the medication is refilled at a low level and then lifted onto a support platform, this still places a strain on the lower back.

負式動力散布機における支持台構造を提供せんと
するものである。 In this invention, the support base is formed by a telescopic, bell-shaped air bag, and air can be supplied into the air bag from the air blower of the sprayer main body, so that the height position of the sprayer main body can be changed by expanding the air bag. By configuring the main body to be raised, the main body of the spreader can be raised without putting strain on the lower back, and the present invention aims to provide a support structure for a backpack-type power spreader that can be carried on one's back. .

作業にも何ら支障はないものである。 Also, when carrying this spreader body a on your back, first,
Place the sprayer main body a on the airbag 1 in the contracted state, connect the tip of the air supply pipe 20 to the air supply port 18, close the spraying intermittent shutter 17,
and the air supply intermittent shutter 19 is opened,
Also, the supply amount adjustment shutter 15 is closed,
When the blower fan 10 is driven, the air supply pipe 1
Since air is supplied to the air bag 1 through the air bag 1, the air bag 1 is extended by gradually moving the throttle lever 21 to the high speed side while lightly pressing and supporting the sprayer main body a. If the spreader main body a is raised to a high position and the spreader main body a is carried on one's back in the same state, no strain will be placed on the lower back. Therefore, when replenishing the chemical storage tank 5 of the sprayer body a and performing the spraying work, the sprayer body a is placed on the air bag 1 in the contracted state,
After replenishing the medicine at a low position, it is sufficient to simply extend the airbag 1, and there is no problem in replenishing the medicine.

支障なく行えるという効果を奏する。 According to the present invention, the support base is formed of a telescopic, bell-shaped air bag, and an air supply port is opened in the middle of the chemical spraying pipe that is connected to the air blower floor of the sprayer main body. The air bag is connected to the air bag via an air supply pipe to supply air into the air bag, and the height position of the sprayer body can be changed by expanding the air bag, so the height of the sprayer body can be changed by expanding the air bag. The main body of the spreader can be raised without putting any strain on it or without the help of an assistant.
This can be carried on one's back without causing any problems in the lower back, and it is also effective in replenishing medicines without any problems.
