Technical Field

The invention discloses divisional application of a bulk cargo loading device (application number: 2017114737411), relates to a storage machine, and particularly relates to a bulk cargo loading machine.

Background

In the circulation process of large-scale cargo bins (such as grain bins, mines, ports, pharmaceutical factories, etc.) for storing powdery or granular cargos, in order to accelerate the shipping speed and save the cost, the 'four-bulk' technology, namely bulk, bulk transportation, bulk unloading and bulk storage technology, is generally adopted. When the bulk materials are transferred, the bulk materials are often in two forms, namely bagged bulk materials or vehicle bulk materials, and the latter bulk materials are convenient to unload and are more suitable for large-scale bulk material transportation.

The conventional bulk cargo truck is usually loaded and transported by a grab bucket or a transfer belt, bulk cargo poured into the hopper can automatically flow into a truck below the hopper, the conventional overhead hopper has the defects that ① generates a large amount of dust during the process of unloading the bulk cargo by the overhead hopper, so that the environment is polluted, the dust in the whole loading and unloading area is diffused seriously, the safety and the environment are influenced, ② a discharging port is far away from the truck, the flying dust is easily generated when a door machine unloads the cargo, the distance of a conveyor belt is increased in the case of a cargo delivery cabin with a high position (port cabin unloading and the like), or two layers of platforms of overhead hoppers are adopted, such as a dustproof overhead hopper (201320111464.0), while a mode of a discharging port valve is usually adopted in the case of the double layers of overhead hoppers, the existing discharging port valve has a certain opening distance with the discharging port of a lower layer platform, the bulk cargo is easy to fall and difficult to clean, the loss and waste are caused, the loading quality is influenced by the fact that some cargos fall from the position which is too high, and the hopper can not easily fall to the hopper, and the gravity of the hopper can reduce the dust easily, and the dust can be easily reduced when the cargo falls from the middle of the hopper and the hopper falls, and the hopper and the cargo can not easily fall to the hopper and the hopper can be damaged, and the hopper with the hopper, and the hopper, so that the hopper can be easily fall from the hopper can be easily caused.

In embodiment 5, as shown in fig. 13 and 14, this embodiment includes a hopper assembly, a feed conveyor belt 37, a rope roller assembly 33, and a hopper frame. In the present embodiment, the lifting process of the hopper 38 is realized by using a clockwork spring, and the main structure of the present embodiment is the same as that of embodiment 4, only the technical features that are different between the present embodiment and embodiment 4 will be described, and the same technical features will not be described again.

In the present embodiment, the main shaft 6 and the barrel structure 51 are connected through a spring 52, two ends of the spring 52 are respectively fixed on the main shaft 6 and the barrel structure 51, and the spring 52 is installed in a direction such that the spring 52 can be wound when the rope 4 is pulled out.

Rope 4 on be close to the position of lower extreme and be equipped with fixed block 53, the diameter of fixed block 53 is greater than the width of bar hole 54 to when upwards drawing rope 4, can keep off on bar hole 54 through fixed block 53, prevent that rope 4 from continuing upward movement. The fixed block 53 satisfies the upper position of the rope 4: when the fixed block 53 is stopped at the strip hole 54, the hopper 38 is positioned higher than the hopper frame and lower than the end of the feed conveyor 37.

In the present embodiment, because the spring 52 is used as power, the structure of the first motor 36, the first switch 42, the reel gear 34 and the motor gear 35 is eliminated. The second switch 49 is used only to control the activation of the infeed conveyor belt 37.

When the hopper 38 is full, the hopper 38 falls against the elastic force of the spring 52 by gravity, and when the hopper 38 falls to the bottom end to complete discharging, the weight of the hopper 38 becomes smaller, so that the hopper 38 is pulled upward by the spring 52 until the fixing block 53 is clamped at the strip-shaped hole 54.

Compared with embodiment 4, the present embodiment does not need to use a motor, and saves more energy. In addition, because the length of the spiral spring 52 is limited, the spiral spring is only suitable for small material tanks with not very high height, and is also suitable for small-sized well cellar type storage with smaller inlet caliber and shallower tank volume.

Example 6 is shown in FIG. 15. The present embodiment includes a feeding conveyer belt 37, a rope roller assembly 33, a hopper 38, a hopper frame and a first motor 36, wherein the feeding conveyer belt 37, the rope roller assembly 33, the hopper 38, the first motor 36 and their auxiliary structures are the same as those of embodiment 4, the same technical features are not repeated in the present embodiment, and the present embodiment is different from embodiment 1 mainly in the change of the hopper frame.

Example 6 is also applicable to open-air cone-type stacking of mineral material in ports or in cargo areas, in addition to the loading of trucks under the overhead, in which case the rope roller assembly 33 and the hopper frame can be mounted on a mobile car body or a mobile portal frame.
