Description

  The present invention relates to a lottery method such as forklift using an agitator vehicle in various event venues.

As a lottery method for forklift, a method using an Arai-type rotary lottery machine (commonly called “Garapon”, “Garaga”, etc.) is known. The Arai rotary lottery machine rotatably supports a box such as an octagon having a predetermined thickness, and slowly rotates the box in a predetermined direction with a handle attached to the side wall of the box. Thus, one lottery ball is taken out from the box, and the winning grade is determined by the color of the lottery ball.
On the other hand, an agitator vehicle is known as a vehicle for transporting ready-mixed concrete. The agitator wheel has a rotatable tilt drum for stirring and discharging the ready-mixed concrete and is exclusively used for transporting ready-mixed concrete. Since the agitator vehicle may not operate in a period when demand for ready-mixed concrete is low, it would be advantageous if new applications other than transport of ready-made concrete could be found. In addition, the tilting drum of an agitator wheel is usually manufactured by welding spiral blades to the inner peripheral surface of the drum body (see Patent Document 1).
Japanese Patent Laid-Open No. 10-34444

The above-mentioned Arai-type rotary lottery machine is well known as a lottery lottery means and is widely used in event venues and the like. However, since lottery means such as the Arai-type rotary lottery machine are well-known, they have not attracted much interest from visitors, and only the person who performs the lottery can enjoy it on the spot. Further, in the conventional lottery means, a specific lottery medium such as a colored sphere is often used, and the grade of the prize must be limited to several types such as “1st grade to 4th grade”. Furthermore, in the conventional lottery method, the lottery person usually obtains a lottery medium such as a lottery ball and then exchanges the lottery medium for a prize, which requires time and labor for exchanging the lottery medium and the prize. there were.
Therefore, the present invention allows not only the person who draws the lottery but also the surrounding people to enjoy the lottery, increases the types of prizes, and saves the trouble of exchanging lottery media and prizes. The purpose is to provide a lottery method.

As a result of diligent study to solve the above problems, the present inventor can realize a lottery method that meets the above-described purpose by using an agitator vehicle for transporting ready-mixed concrete as a lottery means, The present invention has been completed by finding that it is possible to open the way to use agitator vehicles during periods of low demand for concrete.
The lottery method using an agitator wheel according to the present invention is a lottery method using an agitator wheel provided with a rotatable tilting drum having an opening for charging and discharging ready-mixed concrete at or near the upper end. (A) inserting a plurality of lottery articles (for example, lottery balls, prizes, etc.) into the drum through the opening; and (B) rotating the drum in the rotating direction when discharging the ready-mixed concrete. And rotating the plurality of lottery articles gradually toward the opening in the drum, and (C) discharging at least one of the plurality of lottery articles from the opening. And the step of determining the lottery result by making the first picked up the winning item.
Here, as an example of the drum, a drum main body that forms the outer shape of the drum and a spiral blade formed from the lower end to the upper end of the inner peripheral surface of the drum main body can be cited.

According to the lottery method of the present invention, by using a special vehicle called an agitator car as the lottery means, it is possible to attract a great deal of interest from visitors such as event venues, and the lottery article from the raw concrete discharge section. By performing an unexpected operation of taking out (for example, lottery balls, prizes, etc.), it is possible to entertain the surrounding spectators.
In addition to the lottery medium such as lottery balls for exchanging with prizes, prizes themselves (for example, candy in a box), and articles containing prizes inside ( For example, it is possible to use a product in which a premium is accommodated in a protective member formed by combining two halves of a polystyrene foam. In the case where the lottery item is a prize itself, etc., in addition to being able to save the trouble of exchanging lottery balls and prizes required when the lottery item is a lottery ball, there are many types of prizes. There are advantages such as being able to arrange.

The present invention will be described in detail below with reference to the drawings.
FIG. 1 is a perspective view showing an example of an agitator wheel used in the lottery method of the present invention, and FIG. 2 is a shape of a spiral blade formed on the inner peripheral surface of a tilting drum mounted on the agitator wheel. FIG. 3 is a cross-sectional view showing a state where the tilt drum shown in FIG. 2 is cut by a vertical plane passing through the line AA, and FIG. 4 is shown in FIG. It is sectional drawing for demonstrating the movement order of the goods for lottery in a tilting drum type drum and its peripheral structure.

In FIG. 1, an agitator vehicle 1 includes a driver's seat 2, wheels 3, a loading platform 4, a tilt drum 5, a drum support portion 6, a loading portion 7, a discharge portion 8 and the like.
The drum 5 is rotatably supported by a drum support unit 6. In a normal usage method (conventional use for kneading of ready-mixed concrete), the ready-mixed concrete is input into the drum 5 through the input unit 7, and the discharge unit 8. The concrete is discharged from the drum 5 through. Specifically, after putting the ready-mixed concrete manufactured in the ready-mixed concrete factory into the input section 7, the agitator vehicle 1 is driven to the construction site by rotating the drum 5 and stirring the ready-mixed concrete. After arriving at the station, the concrete is discharged by discharging the ready-mixed concrete from the discharge section 8.
In the present invention, the drum 5 is not for containing and stirring ready-mixed concrete, but for storing lottery articles such as lottery balls and stirring (mixing) them as necessary. Used to discharge one by one.

As shown in FIGS. 2 and 3, the drum 5 includes a drum portion 10 that is rotatably supported by a drum support portion 6 (see FIG. 1) about the AA line, and an inner peripheral surface of the drum portion 10. It is comprised from the helical blade | wings 11 and 12 formed by adhering to this internal peripheral surface ranging from a lower end to an upper end. As shown in FIG. 3, the trunk portion 10 has an outer peripheral wall 10a, a bottom wall 10b, and an opening portion 10c, and a plurality of lottery articles such as lottery balls thrown through the opening portion 10c are placed on the trunk portion. It accumulates in the lower part of the internal space of the part 10.
The spiral blade 11 is formed on the circumference of the upper end of the inner peripheral surface of the trunk portion 10 from a predetermined point near or on the circumference of the lower end of the inner peripheral surface (the inner surface of the outer peripheral wall 10a) of the trunk portion 10 or As a plate-like projection piece formed in a spiral shape around the axis (A-A line) of the trunk portion 10 up to a predetermined point in the vicinity thereof, it is fixed on the inner peripheral surface of the trunk portion 10. Yes.
The spiral blade 12 is a point on or near the circumference of the lower end of the inner peripheral surface (the inner surface of the outer peripheral wall 10a) of the trunk portion 10, and the spiral blade 11 is a predetermined point on the circumference. A spiral shape similar to the spiral blade 11 extends from a point shifted by an angle (for example, 180 degrees) to a predetermined point on or near the circumference of the upper end of the inner peripheral surface of the body 10. Are fixed on the inner peripheral surface of the body portion 10 as plate-like projecting pieces formed in the above.
Note that the spiral blades 11 and 12 are not limited to the shape in which the cross-section rises linearly from the outer peripheral wall 10a as shown in FIG. 3, and may have other shapes. For example, the edge of the upper ends of the blades 11 and 12 which are plate-like projection pieces may be bent toward the opening 10c so that the cross-section rises from the outer peripheral wall 10a into a substantially L shape. . A drum provided with a spiral blade having such a configuration is described in, for example, Japanese Patent Application Laid-Open No. 2003-191224.

Since the pair of blades 11 and 12 are formed in a spiral shape on the inner peripheral surface of the body portion 10, when the body portion 10 rotates in a predetermined direction (forward direction), the contents ( It acts to move the lottery article in the direction from the opening 10c toward the bottom wall 10b, and when the barrel 10 rotates in the opposite direction (reverse direction), the contents ( The lottery article) is moved in the direction from the bottom wall 10b toward the opening 10c.
Although the detailed structure of the drum support 6 (see FIG. 1) is omitted, a drum center shaft disposed on the front end (bottom wall 10b side) of the body 10 and the rear of the body 10 It has a three-point support structure consisting of two rollers for receiving a drum tire mounted on (a portion close to the opening 10c).
The throwing part 7 is a guide path for putting a lottery article such as a lottery ball into the trunk part 10, and has openings 7a and 7b at both ends. The opening 7 a is provided along the axis of the body 10 and at a position at an appropriate depth from the opening 10 c in the internal space of the body 10. The opening 7b is provided at a position higher than the opening 7a and spaced outward from the opening 10c of the body 10 (the direction opposite to the direction toward the bottom wall 10b).
The discharge portion 8 is formed integrally with a casing portion 8a that covers the opening 10c of the body portion 10 from the outside and a passage portion 8b that extends downward from the casing portion 8a. A lottery item such as a lottery ball discharged from the body portion 10 falls downward through the passage portion 8b and is taken out by a person who performs the lottery.

Next, the procedure of the lottery method of the present invention will be described with reference to FIG.
First, a plurality of lottery articles 13 are loaded into the drum 5 through the opening 7 b of the loading unit 7.
Examples of the lottery article include a lottery medium such as a lottery ball, a prize itself, a thing that contains a prize inside, and the like.
Here, examples of the lottery balls include spheres having predetermined diameters that are color-coded into a plurality of types such as white balls, blue balls, yellow balls, and red balls. The shape of the lottery balls is not limited to a sphere, and may be a rugby ball shape, a dice shape (substantially cubic shape), a disk shape, or the like. Also, the size of the lottery balls can be changed variously. Various lottery balls having different shapes and sizes can be used at the same time.
Examples of giveaways include boxed sweets, stuffed animals, boxed tissue paper, cupped instant noodles, and the like. When the prize itself is used as a lottery article, it is necessary to select a prize that does not collide with each other in the drum 5 and is not deformed. For example, a soft drink in an aluminum can is not suitable as a prize in this example because it may be deformed when thrown.
Examples of items containing premiums are small electrical products such as transistor radios, food products such as canned foods, etc., in the internal space of a protective member made by combining two halves of polystyrene foam. The ones that house the prizes are listed. In this case, the two molded articles made of polystyrene foam are fastened with a string or the like when put into the drum 5, and after being discharged from the drum 5, the string or the like is unwound to take out the contents premium. do it.

After putting a plurality of lottery articles 13 into the drum 5, the drum 5 is rotated in the forward direction (the direction of rotation when the ready-mixed concrete is kneaded) as necessary. Thereby, the plurality of lottery articles 13 in the drum 5 are agitated, and the positional relationship with each other varies. That is, by performing this rotation operation, the positional relationship between the plurality of lottery articles 13 accumulated in the lower part in the drum 5 is independent of the order of insertion between the articles constituting the plurality of lottery articles 13. It will be chaotic and the fairness of the lottery will be ensured.
In the present invention, the operation of rotating the drum 5 in the forward direction and the operation of rotating the drum 5 in the reverse direction may be alternately repeated a predetermined number of times. In this case, the disorder of the positional relationship among the plurality of lottery articles 13 in the drum 5 is further increased.

  Next, in order to move the plurality of lottery articles 13 in the drum 5 toward the opening 10c, the drum 5 is rotated in the reverse direction (the rotation direction when the ready-mixed concrete is discharged). The plurality of lottery articles 13 are placed one by one on either the spiral blade 11 or the spiral blade 12, and gradually move toward the opening 10c. In addition, when the lottery article 13 is a spherical lottery ball, an appropriate number (for example, about 4 to 5) of lottery articles 13 are arranged in series on the spiral blades 11 and 12 in a dango shape. In this state, it moves toward the opening 10c.

The lottery article 13 that has been moved to the opening 10c while being placed on the spiral blades 11 and 12 is discharged from the opening 10c and then dropped downward through the passage portion 8b of the discharge unit 8. And is taken out from the discharge port 8c.
The result of the lottery is determined, for example, by an agreement such that the lottery article 13 taken out first from the discharge port 8c is selected as the winning item.
When the lottery article 13 is a lottery ball, the lottery is completed by exchanging the lottery ball and the corresponding prize. In the present invention, different lottery balls having different shapes and sizes are used at the same time, unlike a lottery ball of a conventional Arai type rotary lottery machine that has a predetermined diameter determined by the size of a discharge port (round hole). Therefore, various types of prizes corresponding to these various types of lottery balls can be prepared.
When the lottery article 13 is a prize itself or a thing containing a prize, the lottery article 13 taken out from the discharge port 8c is provided as a prize as it is. In this case, the labor for exchanging the lottery article 13 and the prize is saved, so that it is possible to simultaneously reduce labor on the side providing the prize and to quickly obtain the prize on the side receiving the prize. Also, the same number of prizes as the number of prizes can be prepared.

It is a perspective view which shows an example of the agitator vehicle used for the lottery method of this invention. It is a perspective view which shows an example of the shape and attachment position of the spiral blade | wing currently formed in the inner peripheral surface of the tilting drum type drum mounted in the agitator wheel. It is sectional drawing which shows the state which cut | disconnected the tilting drum type drum shown in FIG. 2 by the vertical plane which passes along AA. FIG. 4 is a cross-sectional view for explaining a moving order of lottery articles in the tilt drum type drum and its peripheral structure shown in FIG. 3.
