Description

[Detailed description of the invention] This invention is a vehicle-mounted type in which a frame equipped with a drug tank and a plurality of nozzles connected to the drug tank via a pump is mounted on the rear of a vehicle such as a tractor. This invention relates to a foldable stand that is used to place a sprayer on the ground when it is not mounted on a vehicle.

As shown in FIG. 1, a conventional stand of this type has a frame 3 equipped with a drug tank 1 and a plurality of nozzles (not shown) connected to the drug tank 1 via a pump (not shown), etc. The stand body 4 is detachably mounted on the rear part of a vehicle such as a tractor that can be driven by a frame 3, and a stand main body 4 is attached below the frame 3. A pair of brackets 5a and 5b are formed at the bottom of the stand body 4, facing each other at a certain distance. On the brackets 5a and 5b, the bases of legs 7a and 7b, which are constructed by framing rod-shaped legs 6a and 6b of different lengths into a substantially H-shape, each pair having the same length, are attached to a support shaft 8a. , 8b, and a folded position (indicated by a two-dot chain line in the same figure) in which both legs 7a and 7b are vertically stacked substantially horizontally, and an assembled position in which they are substantially vertical. (shown by the solid line in the figure).
Furthermore, small holes 9a and 9b are formed at the distal end sides of both leg bodies 7a and 7b, respectively. and both leg bodies 7a,
Small holes 10a, 10b, 11a, and 11b are formed in the brackets 5a and 5b, respectively, and the small holes 10a, 10b, 11a, and 11b communicate with each other in the folded position and the assembled position of the bracket 7b, and the small holes 9a, 10a, and 9b communicate with each other in these positions. 10b, or a fixing pin 12 that passes through 9a and 11a and 9b and 11b, respectively.
a, 12b are provided. Fixed pins 12a, 12
b fixes the legs 7a, 7b in the folded or assembled position, respectively.

However, the conventional stand has both legs 7a and 7b.
In this case, the positional relationship between the support shafts 8a, 8b and the small holes 9a, 9b is such that the support shafts 8a, 8b are connected to both the legs 7a,
The small holes 9a and 9b are located on the base side of the support shaft 8.
It is located on the distal end side of both leg bodies 7a, 7b with respect to a, 8b. Therefore, both leg bodies 7a,
In order to fold the two support shafts 8a, 8b so that they overlap each other as shown by the two-dot chain line in FIG. For this reason, as mentioned above, the length of one leg 7a must be made longer, and both legs 7a and 7b cannot be made in the same shape, but different ones must be made. Costs are rising. In addition, a small hole 9 for fixing
Since both a and 9b are drilled on the distal end side of the support shafts 8a and 8b, they are drilled further downward along with the lower support shaft 8b, and therefore the bracket 5b is extended further downward to form the small hole 9b. Since the lower end of the bracket 5b is projected further downward in the folded position, there is a problem that the minimum ground height when folded is lowered.

This idea was devised in view of the above-mentioned circumstances, and its purpose was to enable a pair of legs of the same length to be swingably supported by support shafts that are disposed vertically offset from each other. A small hole is drilled at the distal end of the upper support shaft of the leg that is pivotally supported by the upper support shaft, and a small hole is bored at the proximal end of the lower support shaft of the leg that is supported by the lower support shaft. A small hole is formed in the side, and a small hole communicating with both the small holes is formed in the stand body in the folded position in which the legs are placed almost horizontally on top of each other, and in the assembled position in which they are in a vertical position relative to each other. By providing a fixing pin that passes through both small holes that communicate with each other in the folded and assembled positions, both legs can be made to have the same shape and common, reducing manufacturing costs. For the legs that are supported by the lower support shaft, the small hole for passing through the fixing pin that is drilled in the body is drilled at the base end of the lower support shaft, so the stand body can be raised higher. An object of the present invention is to provide a stand for a vehicle-mounted sprayer, which can increase the minimum ground height in a folded position.

This invention will be explained in detail below based on the accompanying drawings.

FIG. 2 is a plan view of a boom sprayer that is equipped with a stand for a vehicle-mounted sprayer according to the present invention, and is equipped with a boom that is disposed with a large number of nozzles and is retractable. In the drawing, 20 is a tractor that is a vehicle that can run on wheels 21. At the rear of the tractor 20, a drug tank 22 and a number of nozzles 23 are arranged, as well as a telescopic boom 24, etc. A frame 25 provided with a frame 25 is removably mounted. Note that the large number of nozzles 23 are connected to the drug tank 22 via a pump (not shown).

3 and 4 are side and rear views of the stand according to this invention shown in FIG.
Reference numeral 22 denotes the aforementioned drug tank, and the front and rear surfaces of the drug tank 22 are held by the frame 25, which is formed by substantially opposing torii-shaped members. frame 25
A square frame-shaped stand main body 26, which also forms the lower part, is attached to the lower part of the stand. Brackets 27a and 27b are provided at approximately the four corners of the stand body 26, respectively.
are arranged in parallel and facing each other in the longitudinal direction of the tractor 20. Both brackets 27a and 27b have leg bodies 30a and 30b, each of which has a pair of rod-shaped leg parts 28a and 28b of substantially the same length, each framed in a substantially H-shape by cross members 29a and 29b. The body 30a or 30b is mounted so as to be swingable in the front-rear direction, which is a direction facing each other, by an upper support shaft 31a and a lower support shaft 31b, which have a vertical height difference greater than the thickness of the body 30a or 30b. Note that both support shafts 3
The distance between 1a and 31b is at least the length of leg 30a or 30b. At least one leg 28a of the leg 30a that is pivotally supported by the upper support shaft 31a is provided at a position having a distance A away from the support shaft 31a toward the distal end by at least the thickness of the leg 30a. A small hole 32a is bored. Further, at least one leg portion 28b of the leg body 30b that is supported by the lower support shaft 31b is provided with a small hole 32b at a position closer to the base end by the same distance A as described above from the support shaft 31b. Ru. The bracket 27a has a portion located on the circumference with the distance A as the radius around the support shaft 31a, and located in the direction of the bracket 28b, which faces the support shaft 31a in a substantially vertical downward direction and in a substantially horizontal direction. Small holes 33a and 34a are formed respectively. Further, the bracket 27b has small holes 33b and 34b, respectively, on a circumference having the same distance A as a radius, located substantially vertically above and substantially horizontally to the supporting shaft 31b, and in the opposite direction to the opposing bracket 27a. is drilled. Furthermore, the assembly positions of the legs 30a and 30b shown in solid lines in FIG.
Or, in the folded state in which the legs 30a and 30b shown by two-dot chain lines are placed almost horizontally on top of each other, the small holes 32a and 33a and 32b and 33
b, or small holes 32a and 34a and 32b and 34b
are communicated with each other, but at that time, the legs 30a and 30 are connected in their respective states through both small holes.
Fixing pins 35 that keep b in a fixed state are respectively disposed so as to be freely insertable and removable. Note that a ring-shaped handle 35' is formed on the fixing pin 35.

Since this invention is as described above, the cost of the stand can be reduced by making the lengths and other shapes of the legs 30a and 30b the same and using them in common. In addition, the minimum ground height of both brackets at the bottom of the stand body can be made higher, so when the legs are folded, the minimum ground height is higher than that of conventional stands. This has the effect that even when spraying is performed on the field, the lower part is less likely to come into contact with and damage the crops to be sprayed.
