Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to the structure of a trolley on which a power spreader is mounted and used for spraying work.

(b) Conventional technology Conventionally, when spreading fertilizer, etc. using a backpack-type power spreader, it weighs over 30 kg when the main unit is filled with fuel and fertilizer, and the power spreader must be carried on the back during work. It was very hard work. Therefore, in recent years, power spreaders have been mounted on trolleys to carry out the spraying work. Such carts for power spreaders are well known, and are disclosed in, for example, Japanese Utility Model Application Publication No. 61-139776 and Japanese Utility Model Application No. 139776.
61-195364 had become publicly known.

These were trolleys with one wheel at the front and rollers at the rear, and the handles could be changed from front to back.

(c) Problems that the invention aims to solve When performing spraying work with the above configuration,
It had one front wheel and a rear roller that could rotate left and right, making it unstable and requiring strong support for the handlebars at all times. In addition, the handle could be changed by changing it from front to back, which was a tedious task.

(d) Means for solving the problem In view of the above points, the present invention is constructed as follows.

This is a hand-held trolley on which a power spreader or the like is mounted to carry out spreading work, with three or more wheels provided on each of the front and rear sides of the body frame, with the center wheel being able to rotate upward.

Further, a rotary frame is rotatably mounted on the central portion of the body frame, and a handle protruding from the rotary frame is configured to be able to be moved back and forth.

(E) Embodiment of the invention The purpose of the invention is as described above, and the structure of the invention will be explained based on the structure of the embodiment shown in the attached drawings.

FIG. 1 is an overall side view of the power spreader trolley of the present invention on which the power spreader is mounted. Figure 2 is a side sectional view of the fuselage frame. Figure 3 is a front view of the running wheels. Figure 4 is also a side view. FIG. 5 is a front sectional view of the rotating part. FIG. 6 is a sectional view taken along the line X-X.

Referring to FIG. 1, the overall configuration of a hand-held trolley for mounting the power spreader of the present invention will be explained.A rotary frame 2 is placed on the body frame 1, and the power spreader A is placed. The power spreader A is a backpack-type power spreader that is used as is. A tank 7, a drug tank 8, etc. are installed.

A connecting hose 11 is connected to the discharge port at the tip of the fan case 5, and a powder spray pipe 12 is connected to the tip of the connecting hose 11, so that fertilizer and the like can be spread. Incidentally, if a long jet pipe or the like is connected instead of the dusting jet pipe 11, powder materials etc. can be scattered.

A lower end of a handle 13 is fixed to the rear end of the rotating frame 2, and a stay 15 on which a basket 14 is placed is protruded rearward from the middle of the handle 13, and above the stay 15, a metering lever 16 is mounted. An extension lever 17 is attached so as to be slidable up and down, and a support bracket 19 is provided between the handle 13 to support the connecting hose 11 and to adjust the angle.

As shown in FIG. 2, the rotary frame 2 has a pivot bolt 20 passed through the center of the rotary frame 2 and the fuselage frame 1, and is pivotally fixed with a nut 21, so that the rotary frame 2 is attached to the fuselage frame 1. 2 is rotatable. A locking pin 22 is provided at the rear of the rotating frame 2 and at the rear and front of the fuselage frame 1.
Pin holes 2a, 1a, 1a are opened for inserting the rotating frame 2 on which the power spreader A is placed.
When rotating 180 degrees and switching back and forth, the locking pin 22
It can be fixed in place. Note that the rotating frame 2 may be provided with rollers 20, bearings, etc. to facilitate rotation.

Further, the structure of the running wheels 9, 9...support parts provided at the front and rear ends of the fuselage frame 1 will be explained with reference to FIGS. 3 to 6. Support frames protruding forward and backward from both sides of the fuselage frame 1 A shaft 26 is provided at the tips of 25 and 25, respectively, protruding inwardly,
Outer running wheels 9L and 9R are rotatably fitted into the shaft 26, and disks 27 and 27 made of wear-resistant synthetic resin or the like are fitted inside the wheels. 9a in FIG. 5 is a wheel, 28, 29
is color, and 30 is bushy.

A cam plate 3 is provided at the inner end of the shaft 26.
1 is fixed, and the elongated hole 32 of the arm 32 is formed inside the arm 32.
a is inserted and secured with a nut 33. The cam plate 31 has an arc-shaped elongated hole 31a, both ends of which serve as locking portions, and a pin 34 protruding from the arm 32 is inserted into the elongated hole 31a.

The arm 32 is configured in a U-shape, and has a pin 35 protruding from its tip, and a spring 36 is interposed between the pin 35 and the shaft 26 to tension the arm 32. The wheel shaft 37 is horizontally mounted, and the running wheels 9M, 9M, 9M are rotatably inserted therein.

(F) Effect of the invention In such a configuration, when the locking pin 22 on the rotating frame 2 is removed, the handle 13 can be rotated left and right around the pivot bolt 20, and the rotating frame 2
can be rotated 180 degrees. Then, by inserting the locking pin 22 into the pin hole 2a again, the rotating frame 2 can be fixed.

Further, from the state in which the central running wheel 9M is projected forward or backward as shown in FIG. 1, the arm 32 is pushed toward the main body against the biasing force of the spring 36, and the pin 34 is inserted into the locking part of the elongated hole 32a. If it is released from the position and rotated upward, the center running wheel 9M can be maintained in an upwardly lifted state as shown in FIGS. 3 to 6.
When traveling on a concrete ridge or the like, the vehicle can travel stably by being guided by the disks 27, 27 and the central running wheel 9M. On the other hand, when traveling on a flat area, the arm 32 can be kept at the same height as the running wheels 9L and 9R on both sides by pushing it downward to release it from the locking part of the elongated hole 32a and tilting it forward. Nono.

(g) Effects of the invention With the above configuration, the invention provides the following effects.

First, since the spreader is mounted on the rotary frame 2 so that it can rotate, the handle can be easily changed back and forth, making reciprocating work easier.

Secondly, since the center of the running wheel can be rotated up and down, it can be guided on both sides when running on concrete ridges, etc., allowing stable running, and on flat areas both sides and the center can also touch the ground. This allows the vehicle to run stably without wobbling from side to side.
