At this time, from the viewpoint of the sealing property for preventing the contents in the tank from leaking outside during work or the like, especially when the contents are liquid, the space between the tank and the main body of the machine is required. It is preferable that the tightening force for fixing the tank is large. In particular, when a powerful medicine such as a pesticide is used in the case of a backpack power spreader or the like, the necessity is great from the viewpoint of ensuring safety for workers. However, if the tightening force is too large, a rubber or other packing usually provided between the tank and the body of the machine is likely to be worn or deteriorated, and as a result, the life of the packing may be shortened. In addition, with the deformation of the packing, the tightening force may weaken over time. Also, from the viewpoint of sealing performance, it may not be sufficient to fasten and fix a tank having a fixed width and length by tightening one point on each side of the tank. In particular, in a configuration in which the tank is located above and the support main body is located below, the weight of the contents in the tank makes it easy to apply a separating force to the tank tightening device, for example, when the tank is inclined during work. Under such circumstances, it is troublesome to adjust the screwing amount of the hook bolt and to appropriately adjust the tightening force every time the tank is replaced, for example, every time the tank is replaced from a powder tank to a liquid tank. Furthermore, in order to change the tightening position together with the tightening force, it is necessary to replace the hook bolt with a bifurcated or more branched hook bolt extending along the width direction of the tank each time, and it still requires work man-hours and requires small parts. Certain unused hook bolt storage problems arise. Such storage is cumbersome and generally results in losing unused hook bolts.

The method of using the tank tightening device 16 having the above configuration will be described below. First, after the hook portion 44 is hooked on the locking shaft 48 from the fastening release state as shown in FIG. 7, the fastening lever 28 is pushed down in the direction of arrow A, and the fastening state in FIG. Become. Looking at the positional relationship between the three shafts 40, 42, 48 in such a tightened state, the pivot 42 that supports the intermediate member 30 is located between the locking shaft 48 of the upper mounting base projection 20 and the lower mounting shaft 48. Base 2
2 is not on the line Y connecting the two pivots 40, in other words, the pivot 42 of the intermediate member 30 is inward beyond the dead point on the line Y, so that the tank 12 is over dead point. The tightened and fixed state is maintained. At this time, the concave portions 50a, 5a of the branch portions 44a, 44b, 44c
0b and 50c are engaged with the locking shaft 48, and the tightening force of the concave portions 50a and 50c on both sides increases the central concave portion 50b.
As compared with the tightening force of the upper tank 12, the tightening position in the front-rear width direction of the upper tank 12 is secured with a relatively large distance. Even when a force is applied not only in the width direction but also in an oblique direction, the fastening can be reliably maintained even in a heavy tank weighing about 30 kg at the time of setting the liquid agent. From this point of view, it is more advantageous that the length of the locking shaft 48 is larger in accordance with the distance between the recesses 50a and 50c on both sides in the front-rear width direction of the tank 12.

Conversely, in order to release the tightening device 16, the operating portion 38 at the lower end of the tightening lever 28 is pinched and pulled in the direction opposite to the arrow A, that is, upwards, so that the pivot 4
The hook 2 is moved outward through the dead point, and the hook portion 44 can be detached from the locking shaft 48 of the upper mounting base projection 20. Next, a case in which the above-described liquid material tank setting is changed to a powder material tank setting with a lighter working weight will be described below. First, the liquid agent tank 1
2 is released and removed, and the lower support body 14 is removed.
Then, the tank bottom plate 19 is removed, and the metering valve device 60 with the packing 18 is attached. Next, after positioning the powder tank 12 having the short locking shaft 48 'which does not protrude forward and backward on the lower support body 14, the tank 12 is tightened by the above-described method.

At this time, unlike the case of the liquid material tank,
As described above, since only the central concave portion 50b formed deep by the predetermined dimension d is engaged with the locking shaft 48 ', the tightening force for the predetermined dimension d can be obtained without adjusting the screwing amount of the hook bolt 32. Is automatically reduced, so that the tank 12 can be tightened and fixed to the support body 14 without applying an excessively large compressive force to the packing 18. In the case of a powder, unlike a liquid, the required tightening force for preventing leakage to the outside is reduced. In addition, as is apparent from FIG. 6 in particular, the central recess 50b is positioned so as to be hooked on the longitudinal center axis X of the tank 12, so that one point is tightened on each of the left and right sides of the tank 12. However, even with the oblique force on the tank 12, the fastening can be sufficiently maintained. While the preferred embodiments of the present invention have been described above, various changes can be made without departing from the scope or spirit of the present invention, within the scope of the technical matters described in the claims. For example, the tank tightening device 16 is not only installed at two positions on the left and right sides of the tank, but also appropriately according to the tank shape, the amount of the medicine, and the like.
More than one may be installed around the lower part of the tank.
