The present invention relates to a barbecue grilling iron skewers for rotating barbecue which allows each skewer to be rotated at the top of the oven while rotating a plurality of skewers of meat stitched for barbecue grilling in multiple stages. It is about.

Since the discovery of fire, various methods of cooking food have been developed. Today, almost all foods except for a few foods such as sashimi and sashimi are usually cooked using fire.

In addition, depending on the type of fire used, that is, firewood, charcoal, gas fire, heat, such as heat, the recipe may vary, in particular, unlike other foods, meat will have a significant difference in taste depending on the heat source.

The above-described fire-based meat recipes can be divided into four methods: large, grilled, fried, boiled, or smoked, and the grilling method includes roasting and cooking meat by directly exposing the meat to the fire. After placing the meat on the roasting plate, it can be divided into indirect roasting, where meat is cooked by the roasting plate heated by fire.

Among the various kinds of meat recipes described above, the oldest recipe for human beings is barbecue grilled, also known as barbecue. In particular, roasted grilled meat can not only taste meat and taste unique to other meat recipes, As the oil contained in it is naturally removed, it has the advantage of giving a lighter and deeper taste.

However, since barbecue cooking is directly cooked on the meat, it is almost impossible to cook indoors because a lot of smoke is generated during the meat roasting process. Today, people living in a common house such as an apartment have barbecue cooking at home. It is almost impossible to do

Therefore, when the barbecue grill is not a resort, etc., most people can taste barbecue grills at barbecue grill specialty stores, etc. Looking at the conventional barbecue grills for such barbecue grilling are as follows.

The most basic barbecue roaster, as shown in Fig. 1, can hang both ends of the meat skewer 13 with meat F on both sides of the oven 12 for holding a heat source 11 such as a wood fire. In the structure provided with the cradle 14, the meat (F) is rotated by the man directly by the iron skewers 13 in accordance with the grilled state to make the meat (F) evenly cooked.

The roaster described above is inconvenient that a person must turn the skewer 13 directly, and the skewer 13 is small in size and can be mounted in a horizontal direction, and is suitable for home use.

In addition, as a large barbecue roaster that can be used in barbecue grill specialty shops, etc., as shown in FIG. 2, in the state where a plurality of barbecues 13 are mounted in the upper and lower stages along the horizontal direction, they are perpendicular to each other. Two pairs of sprockets (S) and a pair of upper and lower pairs, which are rotated by a motor M in an upper and lower pair on each of left and right sides to reciprocate in the up and down directions along the trajectory. It consists of a pair of drive means (21) consisting of a chain (C) moving along a constant closed loop trajectory by the sprocket (S) of the fire and the oven (12) seated directly under the drive means (21) There is roasting.

At this time, the two pairs of chains (C) may be driven in a horizontal direction, that is, left, right, not vertical, but because the planar area becomes wider, a structure that is generally driven in a vertical direction is used.

As described above, the structure of moving the skewer in the vertical direction along the vertical caterpillar has the advantage that the installation plane is not large, while the homogeneity of cooking is lowered because each skewer does not rotate but only rotates. Since the iron skewers are positioned up and down on the same vertical surface, not only the thermal efficiency is lowered, but also the roasting time becomes longer.

Therefore, as shown in FIG. 3, a plurality of rotary rings 31 are coupled to the outer circumferential surface of the motor driving rotary shaft X around the rotary shaft X in multiple stages up and down, and each rotary ring 31 and the rotary shaft are rotated. In the state in which a plurality of iron skewers 13 are radially seated at (X), the iron skewers 13 rotate around the axis of rotation X simultaneously with the rotation of the rotary ring 31, and immediately below the lowest rotary ring. A barbecue roaster with an oven (12) was installed.

However, the above-described roaster has a disadvantage in that the structure for rotating the skewer and at the same time is complicated, not only increases the manufacturing cost but also has a high failure rate.

The present invention was devised to solve various problems of the conventional barbecued skewer skewer rotating device, so that each skewer is rotated with the revolution in a state where a plurality of skewers are mounted in multiple stages. By enabling the driving of the barbecued iron by only one drive gear provided in the motor and the primary gear coupling, the number of parts required for driving can be minimized, thereby reducing manufacturing costs and maintaining the same. It is an object of the present invention to provide a barbecue grilling iron skewers for barbecue roasting, which is easy to repair and prevents or minimizes operational troubles.

The above object of the present invention is coupled to the bottom rim of the driven gear meshed with the drive gear of the motor and extends downward and an outer hook for fastening each outer portion of a plurality of iron skewers in an up and down direction, and directly below the driven gear. It is fixed by upper and lower stages and is achieved by annular fixing plates formed with holes formed at regular intervals along an imaginary circle.

The barbecued iron skewer revolving device of the present invention has a technical feature in that a plurality of barbecues are orbited and rotated using only one driven gear engaged with the drive gear.

That is, in the barbecue grilling iron skewer revolving device of the present invention, when one driven gear is rotated, a plurality of outer hooks coupled to the driven gear revolves together, a plurality of iron skewers mounted on each outer hook It rotates with its outer hook.
