Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a battery mounting device of a self-propelled sprayer that irrigates, fertilizes, and disinfects vegetables while automatically traveling in the furrows between crops inside a garden house or the like.

[0002]

[Prior Art]

 Conventionally, the technology related to the self-propelled sprayer is known. However, in the prior art, the self-propelled sprayer is often driven by the engine, and the battery is used only at the time of starting, so the possibility of discharging is low.

[0003]

[Issues to be solved by the device]

 However, the number of self-propelled atomizers equipped with a battery in recent years that drive while driving wheels with a motor is increasing, and the battery will be discharged soon after a day or so. In the next work, it will be necessary to charge the battery. However, in order to charge the battery, it is necessary to have a commercial power source close to it, but in gardening houses, there are many cases where there is no commercial power source. is there. In such a case, since the battery 1 was completely covered inside the bonnet, it was necessary to remove the bonnet and take out the battery, which could not be taken out easily.

[0004]

[Means for Solving the Problems]

 The problems to be solved by the present invention are as described above. Next, the means for solving the problems will be described. That is, the hose take-up reel 6, the spray rod 8 and the battery 1 are placed on the upper part of the machine frame, and the hose is automatically taken up and pulled out from the hose take-up reel 6 and the space between the crop ridges. In the self-propelled sprayer traveling on the vehicle, the spray rod 8 is exposed, the hose take-up reel 6 and the battery 1 are housed in the bonnet, and the hose take-up reel 6 is covered with respect to the main bonnet 9. The battery bonnet 2 that covers the battery 1 can be easily removed.

[0005]

[Action]

 Next, the operation will be described. This will be described with reference to FIG. When the self-propelled sprayer sprays a horticultural house or the like, the drive motor M is driven during the spraying operation, so that the battery 1 is discharged quickly. By the end of the day's spraying, most of the battery 1 is in a discharged state, and it is necessary to charge the battery 1 throughout the night to enable the spraying work on the next day. .. At this time, when the commercial power source is not nearby in the part of the gardening house where the self-propelled sprayer is used, such as a nursery facility, the entire self-propelled sprayer is transferred or the battery 1 is removed each time. It needs to be transferred. Conventionally, the battery bonnet 2 and the main bonnet 9 were integrally configured, so that it was not possible to remove only the battery 1. On the other hand, in the case of the present invention, only the battery 1 can be easily removed by removing only the battery bonnet 2 portion with the bolts and nuts without removing the main bonnet 9. .. Since the battery 1 can be removed upward, only the battery 1 can be removed without removing the spray rod 8.

[0006]

【Example】

 Next, an embodiment of the present invention will be described. FIG. 1 is a view showing a state where the battery 1 of the battery mounting device of the self-propelled sprayer of the present invention is removed, FIG. 2 is an overall side view of the self-propelled sprayer, and FIG. 3 is a mounting part of the battery 1. It is a side sectional view. The overall structure will be described with reference to FIG. The frame F is supported by the front and rear four wheels 18. A contact sensor 11 is arranged on the front part of the frame F, and a contact sensor 20 is arranged on the rear part thereof. The contact sensor 11 and the contact sensor 20 are used to switch from the forward / backward states. An abutment column with which the contact sensor 11 and the contact sensor 20 contact each other is erected in the field.

A drive motor M arranged in the front part of the frame F is a power source, drives the front and rear wheels 18, 18 and rotates the hose take-up reel 6 to return the hose when the self-propelled sprayer returns. Wind up. A steering handle 12 is provided at the rear of the machine body for manual steering. Further, a spray rod 8 is erected at the front end of the machine body, and sprays the chemical liquid sent from outside the horticultural house through a hose. The front and rear wheels 18 are supported by a spray rod support mechanism 16. The arrangement on the frame F includes the spray rod 8 from the front end, the battery 1, the hose take-up reel 6 and the steering handle 12. The spray rod 8 and the steering handle 12 are exposed, and the battery 1 and the hose take-up reel 6 are covered with a bonnet.

In the conventional technique, the hood that covers the battery hood 2 and the hose take-up reel 6 is integrally configured, so that even when only the battery 1 is removed, it is necessary to remove the entire hood. It was. In the present invention, in order to eliminate such a problem, the main hood 9 and the battery hood 2 are separately configured. The portion of the battery bonnet 2 covers only the upper portion of the battery 1, which is located between the spray rod 8 and the hose take-up reel 6. Further, a transparent dome bonnet 17 capable of monitoring the winding state of the hose of the internal hose winding reel 6 is attached to the upper part of the main bonnet 9.

Next, a description will be given with reference to FIG. The spray rod support mechanism 16 is supported by the support 10. The support 10 projects from the frame F. Further, the chemical connector 22 is projected by cutting out a part of the battery bonnet 2. The chemical solution connector 22 is connected to the hose wound on the hose take-up reel 6 and is connected to the hose of the spray rod 8. Since the battery mounting bases 4 and 4 are provided on the frame F, and the battery 1 mounted on the battery mounting bases 4 and 4 is fastened by the fastening bolts 5 via the locking metal fittings 3. is there.

A fitting guide 23 is projected from the main bonnet 9 side, and the battery bonnet 2 is fitted to the fitting guide 23 and fixed by bolts and nuts. With this configuration, it is possible to easily attach and detach as shown in FIG. In this case, if the battery 1 cannot be removed without removing the entire main bonnet 9, the spray rod 8 must be removed inevitably. On the other hand, in the battery mounting device of this self-propelled atomizer, the main bonnet 9 and the battery bonnet 2 are separately configured, and the battery bonnet 2 can be removed upward. Therefore, it is not necessary to remove the spray rod 8 and the main bonnet 9.

[0011]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. That is, even when there is no commercial power source nearby such as a gardening house or a nursery facility, the battery 1 can be easily detached by removing the battery bonnet 2 from the battery 1. , You can easily prepare for charging for the next day. Also, when removing the battery bonnet 2 to remove the battery 1, the battery bonnet 2 can be removed in the direction directly above, so it is not necessary to attach and detach the portion of the spray rod 8. The battery 1 can be removed by removing the battery bonnet 2 with the spray port still attached.
