The operating section 5 is disposed at the rear of a frame 22 provided to protrude above the loader main body 1, and as shown in FIG. 3, one end thereof is pushed down by hand to rotate. Note that the rotation is a fan-shaped rotation around a pin 23 inserted above the frame 22. As shown in FIG. 3, a guide piece 26 having a concave curved surface is formed on the lower surface of the operating part 5, and this guide piece 26 faces the internal hollow part of the loader main body 1 and is free. As the operating portion 5 rotates in a fan-shaped manner, the first cam 24 whose one end abuts the guide piece 26 is rotated accordingly.

The other end of the first cam 24 is connected to a square shaft 2 rotatably attached to both sides of the upper front part of the loader main body 1.
The round shaft 15 formed at both ends of the square shaft 25 projects from both left and right sides of the loader body 1.

The rear end portions of a pair of left and right first arms 11, 12 are fixedly attached to both sides of this round shaft 15,
A shovel 4 is rotatably supported at the tips of the first arms 11 and 12, and can be rotated up and down by a predetermined angle. That is, there is a rib 4 at the rear of the shovel 4.
a is provided protrudingly, and a square shaft 17 is provided on this rib 4a.
is fixed. Round shafts 17a, 17a are formed at both ends of this square shaft 17, and these round shafts 17a, 1
7a is rotatably attached to the tips of the first arms 11, 12. Further, the first arm 1
A second arm 13 is attached to the side surface of the shovel 4 for providing a snap action to the shovel 4, and a long hole 14 is formed at the rear of the second arm 13 as shown in the figure. The second arm 13 can be slidably moved by inserting the round shaft 15 of the rotating shaft 25 mentioned above into the elongated hole 14. Further, the upper part of a snap member 16 formed into a substantially triangular shape is rotatably attached to the tip of the second arm 13, and the approximate center of the snap member 16 protrudes from the first arm 11. The shovel 4 is fixed to a round shaft 17a.
It is designed to rotate in unison with the Therefore, the above second arm 13 is attached via the snap member 16.
The sliding movement in the direction of the elongated hole is transmitted to the shovel 4.

Further, a guide pin 20 is provided protruding from the rear part of the second arm 13, and the sliding movement of this guide pin 20 is as follows.
Guide groove 1 attached to the side of loader body 1
It is regulated by a second cam 19 having a diameter of 8, and is adapted to move approximately in a crescent shape (indicated by an arrow in the figure). Therefore, the second arm 13
As the arm 11 moves up and down, it slides along the direction of the elongated hole 14, giving the shovel 4 a snap action. Reference numeral 21 designates an elastic contact piece for pressing the guide pin 20 against the cam 19 in order to temporarily stop the link rotation of the second arm 13. 27 is a spring, and the first arm 1
It is wound around a round shaft 15 so as to be sandwiched between the first arm 11 and the second arm 13, thereby reducing the contact resistance between the first arm 11 and the second arm 13.

Next, a method of using the above embodiment will be explained.

Since the front and rear wheels 2 and 3 are attached to the loader body 1 by being supported by single point supports 9 and 10 provided in the slits 7 and 8, for example, when the loader body 1 is tilted left and right, , the axles 6, 6 supporting the wheels 2, 3 are also tilted to enable meandering travel. This allows you to change the way you drive and expand your play. In such a loader main body 1, since the shovel 4 is in contact with the ground with this weight, sand or the like can be put into the shovel 4 simply by moving it forward. When the operating part 5 is pushed down, the guide piece 26 rotates clockwise around the pin 23, so that the first cam 2 comes into contact with the guide piece 26.
4 also rotates clockwise. This first cam 2
4 is transmitted to the first arms 11 and 12 via the square shaft 25 and the round shaft 15, and this first arm 1
1 and 12 also rotate clockwise. first arm 1
Since the second arm 13 is attached to the side of the first arm, the second arm 13 also rotates clockwise. At this time, the shovel 4 and the sand contained therein may cause the second arm 13 to be pushed through the snap member 16.
tries to slide forward along the long hole 14, but
Since the guide pin 20 provided at the rear of the second arm 13 moves in an arc along the second cam 19, the shovel 4 does not rotate counterclockwise and the sand inside the shovel 4 is removed. Move upwards while storing. In this way, when the operating part 5 is pushed down, the guide pin 20 moves downward, but at the lowest position, it is brought into pressure contact with the second cam 19 by the elastic contact piece 21. Arm 1 of
3. It is possible to temporarily stop the rotation of the first arms 11 and 12 and maintain the shovel 4 in an upwardly raised state. If you push down the operation part 5 further, the first
The arms 11 and 12 further rotate clockwise, but the second arm 13 is rotated by its guide pin 2.
0 is removed from the arcuate portion of the second cam 19,
It moves to the shovel 4 side, and the shovel 4 rotates counterclockwise due to its own weight. Therefore, it falls into the shovel 4 into sand or the like.

Next, when the push-down of the operation part 5 is released, the first arms 11, 12 and the second arm 13 rotate counterclockwise due to their own weight with the shovel 4, but the shovel 4 Since the second arm 1 is tilted counterclockwise with respect to
3 is in a state where the shovel is moved in the 4 direction. Therefore, when the shovel 4 touches the ground, the shovel 4 rotates clockwise, and the second arm 13 moves toward the loader main body 1.
The guide pin 20 moves along the guide groove 18 of the second cam 19 and returns to its original state. The shovel 4 is moved up and down via the first cam 24, the square shaft 25, the round shaft 15, and the first arms 11, 12 that are linked to the operating section 5.
Since the snapping movement is performed via the second arm 13 and the snap member 16, the shovel 4
The lifting and lowering movements as well as the snapping movements can be performed reliably. In addition, the mechanisms of each of the above parts have been designed to be simplified, so there are fewer operational errors.
Moreover, since there are few parts clogged with sand, etc., there is almost no breakage or damage. Furthermore, since it is easy to manufacture and assemble, it has various practical effects such as being able to be provided at an extremely low cost.
