A main body hitch (not shown) is provided at the rear portion of the traveling machine body 1, and the first swing nozzle device 6 is directly mounted on the main body hitch. Further, a base 37 is fixed on the roof 32 of the traveling machine body 1, and a second swing nozzle device 36 is erected at a rear position on the base 37.

First, the configuration of the first swing nozzle device 6 will be described.

As shown in FIG. 2, the first swing nozzle device 6 (a piping system for spraying liquid, which is not related to the gist of the present invention, is omitted) has an upper column 7 and a lower column 8 which are vertically arranged. The upper strut 7 is bent above the tank 4 toward the front of the machine body 1 and falls down.

The upper strut 7 and the lower strut 8 are made of metal members having a U-shaped cross section, which are opposed to each other so as to form a space therein. A shaft member 9 is horizontally inserted through the upper portion of the lower support column 8 with both ends thereof projecting to the left and right sides of the machine body 1. The shaft member 9 is held on the upper part of the lower support column 8 via a bearing 10 so as to be freely rotatable (hereinafter, this shaft member 9 is referred to as a "connecting portion rotating shaft"). .

The lower part of the upper support column 7 and the upper part of the lower support column 8 are connected at their corresponding left and right side surfaces with connecting members 11, 11. The connecting members 11 and 11 are fixedly attached to the upper strut 7, while the lower strut 8 is centered on the rotation axis X1 of the connecting portion rotation shaft 9 when a certain amount of force is applied. Is stopped so as to rotate in the front and rear direction of the machine body 1.

In the illustrated embodiment, as shown in FIG. 3, first, covers 12 and 12 are attached to the left and right sides of the upper portion of the lower support column 8. The covers 12 and 12 cover both end portions of the connecting portion rotating shaft 9 protruding left and right. Circular protrusions 13 and 13 are provided on the outer surfaces of the covers 12 and 12, respectively. The centers of the circular protrusions 13, 13 are located on an extension of the rotation axis X1 of the connecting portion rotation shaft 9. A connecting plate is used as the connecting members 11 and 11, and circular holes 14 and 14 that fit into the circular protruding portions 13 and 13 are provided at the lower portions of the connecting plates 11 and 11. Then, after the connecting plates 11 and 11 are fitted to the covers 12 and 12 so that the circular protrusions 13 and 13 and the circular holes 14 and 14 are fitted to each other, the pressing members 15 and 15 are pressed from above. When tightened, the upper portions 11a, 11a of the connecting plates 11, 11 are fixed to the left and right side surfaces of the lower portion of the upper column 7.

Although not shown, an appropriate holding means is provided between the circular protrusions 13 and 13 and the circular holes 14 and 14 so that the upper support column 7 is upright at the time of work. I'm keeping it.

An appropriate number of shaft members 16a, 16b, 17a, 17b, 17c are provided on the upper strut 7 and the lower strut 8 with appropriate intervals between them, respectively. It is provided so as to penetrate horizontally in the left-right direction. Both ends of these shaft members 16a, 16b, 17a, 17b, 17c project to the left and right sides of each of the columns 7 and 8 (see FIG. 3). The shaft members 16a, 16b, 17a, 17b, 17c are supported by the support columns 7, 8 via bearings 18, respectively, and are supported by the support columns 7, 8 so as to freely rotate about the axis X2. (Hereinafter, the shaft members 16a and 16b provided on the upper strut 7 are referred to as "upper strut cam drive shafts", and the shaft members 17a, 17b and 17c provided on the lower strut 8 are referred to as "lower strut cams". Drive axis ").

All of the upper strut cam drive shafts 16a and 16b, the lower strut cam drive shafts 17a, 17b and 17c, and the connecting portion rotating shaft 9 are rotated in cooperation with each other by appropriate transmission means. Are linked together.

That is, for example, for each of the upper strut cam drive shafts 16a and 16b, each of the lower strut cam drive shafts 17a, 17b and 17c, and the connecting portion rotation shaft 9, two sprocket wheels 19 are provided on each side. Are installed side by side. These sprockets 19 are located in each of the columns 7,8. The sprockets 19 mounted on the vertically adjacent rotating shafts are connected by an endless chain 20, respectively. As a result, if a rotational force is applied to any of the rotating shafts, all the cam drive shafts 16a, 16b, 17a, 17b, 17c and the connecting portion rotating shaft 9 will rotate together. .

In the embodiment shown in the drawings, a drive device 21 such as a motor is attached to the lower portion of the lower support column 8 so that a drive shaft 22 thereof projects into the lower support column 8, and transmission of an appropriate chain or sprocket is performed. The rotational force is appropriately decelerated and transmitted from the drive device 21 to the lowermost cam drive shaft 17c of the lower support column 8 via the means.

Eccentric cams 23 having circular cross sections are attached to both outer ends of the upper strut cam drive shafts 16a, 16b and the lower strut cam drive shafts 17a, 17b, 17c, respectively. These eccentric cams 23 have a larger outer diameter than the cam drive shafts 16a, 16b, 17a, 17b, 17c and have an appropriate thickness. A rear end portion 25a of the nozzle tube 25 is attached to each of the eccentric cams 23 via a spherical bearing 24 arranged radially outward from the axis X2 of each of the cam drive shafts 16a, 16b, 17a, 17b, 17c. Are attached respectively. As a result, when the cam drive shafts 16a, 16b, 17a, 17b, 17c rotate, the rear end portions 25a of the nozzle pipes 25 correspondingly move the cam drive shafts 16a, 16b, 17a, 17b, A circular motion centered on the axis X2 of 17c is performed.

Each of the nozzle tubes 25 extends to the left and right sides of the machine body 1, respectively. Each nozzle tube 25 is designed to have an appropriate length so that it is not too long. This is because if it is too long, there is a risk that the spray car will be caught by trees when traveling between trees in the orchard. In addition, in order to avoid the same danger, the left and right widths of the upper strut 7 and the lower strut 8 are made as narrow as possible, and the protrusion of the nozzle tube 25 held by the respective strut 7, 8 in the left and right direction is shortened. It is desirable to do.

Each of the nozzle tubes 25 is axially supported by being sandwiched by U-shaped support members 26 in the middle of its length direction. Both ends of each nozzle tube 25 can freely swing up and down around the horizontal pivot shaft 27. The U-shaped support member 26 is attached to the end of the bracket 28 so as to be rotatable about the vertical axis X3. The brackets 28 are attached to the left and right side surfaces of the upper strut 7 and the lower strut 8, respectively, and support the nozzle tube 25 via the U-shaped support member 26.

A liquid-sending solution that sends the spray liquid stored in the tank 4 to each of the nozzle pipes 25, and also applies an appropriate braking force to the swing of the nozzle pipes 25 to smooth the movement. The hose 29 is connected to each, and a nozzle 30 for spraying the spray liquid over a wide range is attached to the tip of each nozzle pipe 25.

In the first oscillating nozzle device 6, the liquid can be simultaneously sprayed to the left and right sides of the traveling direction of the traveling machine body 1, and the liquid can be sprayed only to the left or right direction of the traveling machine body 1. In order to disperse the liquid, the discharge of the left and right nozzles 30 can be switched by a control valve (not shown).

Next, the operation of the first swing nozzle device 6 configured as described above will be described.

When performing the spraying work, the upper support column 7 is erected on the lower support column 8. When the drive device 21 is operated, the lower column cam drive shaft 17c provided at the lowermost side of the lower column 8 rotates. The rotating force of the lower strut cam drive shaft 17c is controlled by the sprockets 19 and the chains 20 so that all the rotating shafts (the lower strut cam drive shafts 17b and 17a, the connecting portion rotating shaft 9 and the upper strut cam). It is transmitted to the drive shafts 16b, 16a).

When the lower strut cam drive shafts 17a, 17b, 17c and the upper strut cam drive shafts 16a, 16b rotate, the eccentric cams 23 provided at both outer ends of the respective cam drive shafts are rotated. By the action, the rear end portion 25a of each nozzle tube 25 makes a circular motion about the axis X2 of each cam drive shaft. Here, each of the nozzle pipes 25 is supported by the U-shaped support members 26 so that both ends thereof can freely swing up and down, and the U-shaped support members 26 are arranged in a vertical direction. The brackets 28 are supported so as to freely rotate around the axis X3. Therefore, when the rear end portion 25a of each nozzle tube 25 makes a circular motion, each nozzle tube 25 swings up and down about the shaft fulcrum 27 and the axis X3 of the U-shaped support member 26. Through the reversing rotation, the tip end portions of the nozzle tubes 25, that is, the nozzles 30 also simultaneously perform the swinging motion.

In this way, each nozzle 30 swings smoothly and surely in conjunction with each other, and the spray liquid stored in the tank 4 can be sprayed over a wide range.

On the other hand, when the spreader vehicle equipped with the rocking nozzle device is stored in a warehouse or the like, the upper support column 7 can be tilted forward of the machine body 1, and the upright support column 7 can be used for the tree. Even if the upper strut 7 collides with a branch or the like, the upper strut 7 is configured so as to fall in the front-rear direction about the rotation axis X1 of the connecting portion rotation shaft 9, so that the mechanism provided inside each strut. Has no effect on.

It is preferable that the rocking mechanism portion of each nozzle tube 25 and the bent portion between the upper strut 7 and the lower strut 8 be covered with an appropriate cover to prevent the spray liquid or the like from entering.

Next, the second swing nozzle device 36 will be described.

The second oscillating nozzle device 36 has the same main part as the part of the first oscillating nozzle device 6, and an example of the first oscillating nozzle device 6 is shown. Since it can be easily grasped from FIGS. 2 and 3 showing the above, the detailed internal structure is omitted. Further, for the same reason, only the difference from the first rocking nozzle device 6 will be described and the duplicated description will be omitted.

The second oscillating nozzle device 36, like the first oscillating nozzle device 6, is provided with the nozzles 30 aligned in the vertical direction with respect to the support columns 38, and the nozzles 30 interlock and oscillate. Although the medicine or the like is sprayed on both left and right sides in the traveling direction of the traveling machine body 1 while moving, unlike the first swing nozzle device 6, these are not necessarily divided into an upper strut and a lower strut. Need not be refractively connected to each other.

That is, it suffices that the nozzles 30 are swingably provided on both left and right sides of one support column 38, and the upper support column 7 and the above-mentioned support column 7 as seen in the first swing nozzle device 6 are sufficient. The structure of the connecting portion with the lower column 8 is unnecessary.

The second oscillating nozzle device 36 corresponds to, for example, the first oscillating nozzle device 6 from which the upper support column 7 is removed, and the point at which each nozzle 30 oscillates and each nozzle. The interlocking swing mechanism of 30 is the same as that of the first swing nozzle device 6.

In the second swing nozzle device 36, the nozzles 30 are directed to the left and right sides in the traveling direction of the traveling machine body 1 on the roof 32 of the traveling machine body 1 via the base 37. In this manner, it is erected upright, and when not in use (when the spraying work is not performed), it can be tilted forward from the root of the traveling machine body 1.

Since the second oscillating nozzle device 36 is erected on the roof 32, which is the highest position in the traveling machine body 1, the first oscillating nozzle device 6 is provided. It is also possible to spray chemicals even on trees that are at a high position that cannot be covered with.

Further, when not in use, it can be tilted forward from the root portion of the traveling machine body 1. Therefore, when the spreader is stored in a warehouse or the like, the second swinging nozzle device is used. There is no inconvenience such as 36 getting in the way.

Further, the second oscillating nozzle device 36, like the first oscillating nozzle device 6, is also capable of spraying the liquid only in one of the left and right directions of the traveling machine body 1. The discharge of the left and right nozzles 30 can be switched.

Of course, by providing the nozzle 30 only on one of the left and right sides of the support column 38, and further, by configuring the support column 38 to be rotatable from the root portion around its vertical axis, The spraying direction may be changed in the left-right direction of the traveling machine body 1.

The liquid spraying machine according to this embodiment configured as described above is used, for example, as shown in FIG. 4 according to the topography of the orchard and the height of the trees.

First, in the case where a tree to be sprayed with chemicals or the like is planted on a flat ground, the traveling machine 1 is run along the traveling path 39 between the tree row A and the tree row B while The first rocking nozzle device 6 may be operated to spray chemicals or the like toward the tree rows A and B that are planted on both left and right sides of the traveling path 39.

Further, when there is a steep slope 40 in the orchard, the heights of the trees are significantly different above and below the slope 40. Even in such a case, the liquid dispersion according to the present embodiment is also different. According to the cloth machine, while traveling on the lower traveling path 41, the nozzles on the right side of the first oscillating nozzle device 6 spray the chemicals or the like on the tree row B beside the lower traveling path 41, At the same time, the nozzle 30 on the left side of the second oscillating nozzle device 36 can be operated to spray a chemical agent or the like on the tree row C planted in the upper stage. In this case, needless to say, the first and second oscillating nozzle devices 6 and 36 are used by switching the discharge so that only the nozzles on the side on which the drug or the like should be sprayed are used.

As described above, according to the liquid spraying machine of the present embodiment, the first and second rocking nozzle devices 6 are provided so as to be suitable for the topography of the orchard or the like in which the spraying of chemicals or the like should be performed. , 36, or by properly combining the first and second oscillating nozzle devices 6 and 36, it is possible to efficiently carry out the spraying work of medicines and the like according to the working environment. Becomes

In particular, it is convenient because it is possible to simultaneously spray the chemicals and the like to trees and the like planted in the upper and lower tiers of the slope, which was difficult with the conventional liquid sprayer.

[0058]
