TECHNICAL FIELD OF THE INVENTION
The present invention particularly relates to a wave plate for a liquid tank and a liquid tank structure effective for a backpack-type working machine such as a backpack-type chemical liquid sprayer.
[0002]
[Prior art]
The above-mentioned backpack type chemical sprayer is used while being carried by an operator, but the medicinal solution (liquid) contained in the medicinal solution (liquid) tank undulates as the worker walks, etc. And the center of gravity of the liquid tank is moved, and the shock and the movement of the center of gravity are transmitted to the worker via the liquid tank, whereby the stability of the body is lost. In addition, there is a danger that the worker may fall down on a sloping ground or the like, and the worker may be fatigued and work efficiency may be reduced. Therefore, conventionally, in order to reduce the waving of the contained liquid and the movement of the center of gravity of the liquid tank, a wave canceling plate is provided inside the liquid tank.
[0003]
[Problems to be solved by the invention]
The present invention can effectively reduce the ripples of the liquid in the liquid tank and the movement of the center of gravity of the liquid tank, and can be easily assembled (retrofitted) inside the liquid tank. The present invention relates to a wave plate for a liquid tank and a liquid tank structure that can be assembled into the liquid tank even when the diameter of the mouth is smaller than the inner diameter of the main body.
[0004]
[Means for Solving the Problems]
In order to solve the above problem, the liquid tank wave-breaking plate of the present invention shown in claim 1 is formed in accordance with the vertical cross-section inner contour of the liquid tank, and when assembled into the liquid tank, the wave cross-section plate has A plurality of flexible partition plate members between which liquid passages are formed, and a fixing member connecting the plurality of flexible partition plate members.
[0005]
Note that the expression “formed in accordance with the internal contour of the vertical section” does not mean that the liquid tank is formed in accordance with the internal contour of the complete vertical section. In other words, it means a deformed shape accompanying the cutting off of the upper portion and the liquid passage forming portion in the liquid tank, which do not require the wave canceller, from the complete vertical cross section internal shape of the liquid tank. In addition, the method also includes providing a liquid passage hole in each of the flexible partition plate members together with the formation of the liquid passage.
[0006]
According to the first aspect, when assembling the flexible partition member inside the liquid tank, the flexible partition member can be deformed by freely bending. Therefore, it is easy to assemble the inside of the liquid tank.
[0007]
Furthermore, even in the case of a general liquid tank in which the diameter of the mouth portion is formed smaller than the inner diameter of the main body portion, a flexible partition plate member having a size required inside the main body is removed from the mouth portion. It can be inserted inside and assembled easily.
[0008]
Further, since the plurality of flexible plate members are connected to each other by the fixing member, the plurality of flexible plate members are kept constant inside the liquid tank to reduce waving, and furthermore, the center of gravity of the liquid tank. Movement is reduced.
[0009]
According to an embodiment of the present invention as set forth in claim 2, the plurality of flexible partition members are formed slightly larger than a vertical cross section inner contour of the liquid tank. It is a wave absorber for a tank.
[0010]
According to the embodiment of the second aspect, since the plurality of flexible partition plate members are slightly larger than the internal shape of the liquid tank in the vertical cross section, the flexible partition plate members are assembled inside the liquid tank. In such a case, the flexible partition member is necessarily slightly curved, and is tightly fitted to the inner peripheral surface of the liquid tank. Therefore, the assembled wave canceller is completely and stably fixed, and is not easily deformed or moved by the contained liquid.
[0011]
According to one embodiment of the present invention, an engagement receiving portion is formed on each of opposing side surfaces of the plurality of flexible partition plate members, and the engagement receiving portions are provided at both ends of the fixing member. The wave canceling plate for a liquid tank according to claim 1 or 2, wherein an engaging portion to be adapted and fixed is formed.
[0012]
According to one embodiment shown in the claim 3, a fixing member connecting the plurality of flexible partition plate members is provided between the flexible partition plate members with one touch without using a tool or the like. The plurality of flexible partition plate members can be interposed to fix the flexible partition plate member, and the removal thereof is optional.
[0013]
The liquid tank structure of the present invention according to claim 4 is formed in accordance with the internal contour of the vertical section of the liquid tank, and a liquid passage is formed between the liquid tank and the internal section of the vertical section when the liquid tank is assembled inside the liquid tank. The inside is partitioned into equal left and right volumes by a wave canceling plate composed of a plurality of flexible partition plate members, and a fixing member connecting the plurality of flexible partition plate members. It has a liquid tank structure.
[0014]
According to the liquid tank of the present invention shown in claim 4, the liquid in the liquid tank is equally divided, the center of gravity movement due to the shaking and inclination of the liquid tank and the recoil thereof are reduced, and the safety of the worker is ensured. , Fatigue and work efficiency can be improved.
[0015]
