Description

  The present invention relates to a transport cart apparatus. More specifically, the present invention relates to a cart apparatus that can transport a back-loading sprayer or the like, which is useful for reducing the burden on agricultural workers when farming.

Conventionally, a back-spray type spray working machine has been used for the work of spraying water and agricultural chemicals in a farm field (hereinafter referred to as “agricultural work”). A back-type spray working machine (hereinafter referred to as a “spray working machine”) is convenient because it makes a small turn when performing a farm work or the like in a place where a vehicle loaded with a large power sprayer cannot enter. In addition, when carrying out a spraying operation of a small amount of agricultural chemicals, etc., it is convenient because the preparation for the work can be done quickly.
However, although it is small, the spray work machine has a liquid storage tank, and in the case of a power spray work machine, it also has a power machine, so it has a considerable weight (about 25 kg to 40 kg). . For this reason, even when a healthy adult boy is farming in the middle of the field under a hillside slope or under the branches of shrubs such as fruit trees, the burden of weight is heavy. This is even more true if the worker is a woman or an elderly person.
Therefore, in order to reduce the burden on the spray work machine, a spray work machine transport device (hereinafter referred to as “transport device”) as shown in Patent Document 1 has been proposed.
JP2003-112089

  If the said conveying apparatus is used, the conveying apparatus which mounted the spray working machine can be moved with little force by pushing or pulling. Further, if necessary, the spray working machine can be removed from the transport device, and the worker can carry it on his / her back.

  However, since the transport device according to Patent Document 1 fixes the spray working machine to the transport device with a belt, a band, a fixing bracket, or the like, it takes time and effort to attach and detach the spray work machine. For this reason, there is a problem that it is difficult to quickly attach and detach the spray working machine according to the work situation. In addition, the transport device according to Patent Document 1 repeatedly applies a load to a specific portion in order to fix the spray working machine by fastening with a belt or a fixing bracket, and the portion, particularly the liquid storage tank, is cracked or damaged due to wear. There was also a problem that it was easy.

  Moreover, since the conveying apparatus which concerns on patent document 1 has an axle, there also existed a subject that an axle shaft received resistance from the undergrowth which grew in agricultural fields, such as an orchard, at the time of a movement.

  Furthermore, since the transport device according to Patent Document 1 does not include a brake on the traveling wheel or the like, there is a problem that the transport device becomes unstable during farm work on slopes, particularly orchards provided in mountainous areas. .

By the way, the capacity of the liquid storage tank provided in the back-type spray working machine is not so large, so the water in the tank may be used up during the work. It was troublesome. The same applies to chemicals and fertilizers mixed in water.
For this reason, it is convenient to be able to load a spare liquid storage tank (hereinafter referred to as “reserved tank”) or the like on the transporting device in combination with the backpack type spray working machine.

When working with the spray working machine loaded on the transport device according to Patent Document 1, it is not necessary to carry the spray working machine on the back, so the physical burden on the operator is small. However, since the length of the hose was short, it was possible to spray agricultural chemicals only within the reach of the hose.
For this reason, there have been some people who devise so that work can be performed in a remote place even if the extension hose is combined with the spray working machine loaded on the transport device.
However, during work, the extension hose that is pulled out often moves around the work place without being stowed every time, so the hose may get caught in the auxiliary leg or tire, but the extension hose is housed every time the place is moved. However, there is a problem that the working efficiency decreases when the hose that is entangled or entangled is removed.
