Description

[Detailed description of the invention] [Industrial application field] This invention, when dispersing chemicals, fertilizers, etc., installs a memory element at a desired position on a scale plate attached to the side of the fan case. The metering rod setting position of a power spreader is especially suitable for backpack-style power spraying, which allows you to easily identify the type of fertilizer, spray head type, shutter opening depending on the spraying speed, and expect effective and appropriate spraying work. This invention relates to display devices.

[Conventional technology]

When spraying chemicals or fertilizers using a power spreader, especially a backpack-type power spreader, when contributing to improving the spraying effect by setting the type of chemical or fertilizer, the spray speed, and the opening degree of the shutter that corresponds to the spray head.
() Attach a quick reference table to the instruction manual. ()
Attach the quick reference chart to the desired location on the power spreader.
Furthermore, measures such as (2) users recording each time they spray in a pest control calendar are being adopted.

[The problem that the idea aims to solve]

Among the cases mentioned in the prior art section, in the case of (), the instruction manual may be lost for some reason.
For this reason, it is impossible to read the quick reference table at all, which is extremely inconvenient for the worker. In the case of (), the surface becomes gradually contaminated or degraded as time passes, making visual inspection difficult, and there is also a risk of detachment. In addition, in the case of both () and (), the quick reference table is created as a representative example of the type of chemical or fertilizer, etc., and the spraying speed, so the planting of crops in the field from the user's perspective, It is not always applicable to the growing conditions, and the opening degree of the shutter may be different, so from this point of view, the quick reference table can only be used as a guide when spraying, so it is a little difficult for users. It's hard to avoid feeling inconvenienced. In the case of (), it is cumbersome to record in the pest control calendar, and it is easy to forget the records, and when the previous user was absent, the opening degree of the shutter is unknown. There are disadvantages such as it takes time to confirm the proper opening degree during spraying, and it is difficult to expect improvement in work efficiency.

This idea was proposed by focusing on the above-mentioned drawbacks, and its purpose is to use a backpack-style sprayer, in particular, where the setting position of the metering rod can be easily identified and selected, and an effective and appropriate spraying operation can be expected. It is an object of the present invention to provide a metering rod setting position display device for a power spreader suitable for power spreader.

b ₂ is engaged and held, for example, the spraying speed is displayed near the notch V, and the concave portion _{b 3} of the third memory element Q ₃ is engaged with the convex portion g ₂ of the second memory element Q 2. For example, adjust the shutter opening near the notch V.
After completing this preparation, start the engine 27, rotate the fan, and set the metering rod 4 to the notch 2d corresponding to the number displayed immediately in the notch ν of the third memory element _Q3 . A spraying agent such as agrochemicals stored in the chemical tank 6 can be sprayed onto areas to be sprayed, such as rice fields, fields, afforestation areas, etc., based on a desired shutter opening degree. However, during or after the spraying work carried out under these conditions, the shutter opening may be affected by the type of spraying agent used, the shortage of the spraying agent during the spraying due to differences in the spraying speed, the extent of the remaining amount, etc. By determining the appropriateness of the spray and setting it at the appropriate position, it can be used as a mark for the next spraying, thereby reducing wasted effort, time, and
It is possible to eliminate the reduction in the spraying effect due to overspraying or underspraying, and to perform the spraying work efficiently.In addition, it is possible to reliably correct any inadequacies in the previous spraying, regardless of the operator, and to ensure that the stipulated results are met. The first, second, and third memory elements Q ₁ , Q ₂ ,
Since Q ₃ is rotatably supported separately by the pin 10, it is extremely easy to handle, and the notch ν
It is convenient to be able to confirm the desired conditions by visually checking the edge of the structure, and there is no risk that the structure itself will become particularly complicated, so it can be manufactured robustly and inexpensively.

In the second embodiment, for example, the shutter opening degree and the spraying speed are specified in advance using the memory elements R ₁ and R ₂ , and set at appropriate positions in the through holes i ₁ and i ₂ , respectively. Correspondingly, similarly to the first embodiment, the metering rod 28 can be inserted into and held in one of the notches 29d of the adjustment hole 29 to spray a desired chemical or a dispersing agent such as fertilizer. However, during or after the dispersion, a memory may be added depending on the suitability of the dispersion.
By holding or changing R ₁ and R ₂ in the relevant positions, any number of people can perform the spraying work properly without any inconvenience when changing workers, and the structure is also particularly complicated. There is no risk of doing so. In addition, by providing a protruding piece on the metering rod 28 and adjusting the elastic force of the coil spring 26, the metering rod 28 and the memory element _R1 can be interlocked, and it is possible to prevent forgetting the recording operation. It's convenient.

Furthermore, although three and two memory elements are set respectively in the first and second embodiments, the present invention is not limited to this.
Of course, an appropriate number of memory elements can be selected.

〔effect〕

According to this invention, since the memory element is rotatably or slidably attached to a notch or through hole provided at an appropriate location on a scale plate attached to the side of the fan case of the power spreader, the power spreader By setting and displaying the combinations of information necessary for the spraying work in the memory in advance, multiple pieces of information can be appropriately selected and confirmed when necessary throughout the work. Therefore, for example, when a work is interrupted, it is possible to easily restart the work, and by comparing the work result with the set value of the memory, it is possible to provide suitable information for carrying out the next work.
