Description

VEHICLE FOR PICKUP OF FOOD WASTE}

The present invention relates to a food waste collection vehicle equipped with a hook-type garbage conveying means, and more particularly, a hook-type garbage conveying means capable of maximizing the amount of food waste by distributing food waste uniformly throughout the collection tank. It relates to a food waste collection vehicle provided.

Increasing amounts of waste due to industrial development are emerging as a social problem. Especially, the amount of food waste generated in restaurants and homes is not only gradually increasing, but also polluting the surrounding environment such as decay and odors in a short time. It became the main cause.

In recent years, a lot of means for recycling such food wastes into various fertilizers and feeds have been developed, and a method of collecting food wastes separately is being implemented. However, since development of a dedicated vehicle for collecting such food waste is in its infancy, various problems are exposed.

Such a conventional food waste collection vehicle is equipped with a collection tank having a predetermined size in a loading box of a vehicle, and equipped with a conveying means for moving a baggage containing waste to a collection tank, and moving a baggage containing garbage to a collection tank side. After that, the opening and closing door mounted at the rear of the collection tank is opened and the garbage is loaded into the collection tank.

However, the following food waste collection vehicle has the following problems.

First, since waste is accumulated only at the entrance side through the opening and closing door mounted at the rear of the collection tank, the worker has to continuously move the food waste to the inside, which causes a lot of manpower consumption and delays in working time.

Second, since food waste has a lot of moisture and adhesiveness, it is not evenly distributed in the collection tank and is accumulated in a certain position. Therefore, food waste is concentrated in a part of the collection tank, and the remainder remains empty space. .

In other words, if the baget is moved to the upper side of the collection tank as much as possible and the food waste is put in, the bottom is wide and the upper part is stacked in the form of a mountain, so the upper side remains empty and the loading height of the food waste is increased. When the maximum rise point is reached, it is difficult to add garbage, so the amount of food waste input per unit volume of the collection tank is small.

Recently, the vehicle illustrated in FIG. 1 has been developed to improve the above-mentioned problem.

The food waste collection vehicle is equipped with a food dispersing device for dispersing the food waste so that the inlet of the food waste is installed in the upper center of the collection tank, and the food waste flowing into the inlet is evenly stored in front and rear of the collection tank. It became.

Specifically, the food dispersion device is installed on both ends of the flat pressure plate 20 and the flat pressure plate 20 having a length corresponding to the width of the stacking box 10 to fix the axis of the flat pressure plate 20 to the reference axis The bearing 30 for rotating the flat platen plate, and the hydraulic cylinder 40 is installed in the stacking box 10 to provide power to the flat platen plate 20 so that the flat platen plate 20 is rotated. In addition, the food dispersing device is a flat pressing plate to prevent the hydraulic cylinder 40 from being damaged due to an increase in the load of food applied to the flat pressing plate 20 when the food waste is accommodated to a predetermined level or more into the inside of the loading box 10. A plurality of through grooves 22 are formed inside the 20.

However, the above-mentioned food waste collection vehicle has been formed in the center of the loading port, a variety of problems have arisen because the planar pressure plate is configured to have a rotation radius of about 180 °. For example, the food dispersing device requires a lot of power compared to the food moving means configured to have a rotation radius of 60 to 120 °. In addition, since the food dispersing device rotates from 0 ° to 180 ° of the pressure plate and rotates from 180 ° to 0 ° at a uniform speed, a large load is applied to the hydraulic cylinder 30, thereby causing failure of the hydraulic cylinder 30. There is a problem that occurs frequently. In addition, there is a problem that a separate driving means is required to manually open or close the cover to open or close the inlet or open or close the cover automatically.

Republic of Korea Patent No. 10-0814042 (announced on March 17, 2008) Republic of Korea Patent Publication No. 10-2006-0126072 (Published Dec. 2006) Republic of Korea Patent No. 10-1071957 (October 11, 2011)

Accordingly, an object of the present invention is to distribute food waste with relatively little power inside the collection tank, and to store food waste uniformly so that food waste having a hook-type garbage conveying means capable of storing a large amount of food waste in the collection tank.
