Description

Bulk grain funnel for grain wharf Technical Field The invention relates to a device for supplying bulk materials to a conveyor, in particular to a bulk grain hopper for a grain wharf. Background Bulk grain funnels for grain terminals are key devices for handling and transferring bulk grains, seeds and other dry bulk materials. Bulk grain funnels play a central role in grain storage and logistics chains, particularly in the link of unloading grains from a transport ship to a warehouse or loading grains from a warehouse to a transport. However, a significant disadvantage of the conventional bulk grain hopper design is that its top opening is too large (e.g., 7 meters by 7 meters), which, while facilitating rapid bulk grain flow, also exposes the hopper to rain attack during open air operation. Once the rainwater enters the funnel, the moisture content of the grains can be increased, so that mildew or decay can be initiated, and a serious threat is formed to the quality of the grains and the food safety. In order to overcome the challenge, measures of adding a fixed or movable iron cover plate or awning above a bulk grain hopper are commonly adopted in the industry, so that a waterproof effect is achieved. While these covers or canopies can largely prevent rain from directly entering the funnel, they themselves introduce new problems. First, the broad plane formed by the canopy after deployment is prone to collecting rain water, resulting in a pool of rain water that accumulates on the canopy surface. Secondly, after severe weather, when the awning needs to be retracted, accumulated rainwater can suddenly pour down and directly flow into the bulk grain hopper, so that the probability of grain wetting can be increased accidentally, and the risk of grain quality damage can be aggravated. Disclosure of Invention In view of the above, the invention provides a bulk grain funnel for a grain wharf, which can overcome the defects that when a awning is arranged above the existing bulk grain funnel for blocking rain, rainwater is easy to accumulate on the surface of the awning to form a pool, and when the awning is retracted, the accumulated water can suddenly pour down and directly flow into the bulk grain funnel, so that the grain quality is damaged. The bulk grain funnel for the grain wharf comprises a bulk grain funnel body, a placing seat, a fixing seat, a driving motor I, a rotating seat, telescopic pipes, an air cylinder, an inserting rod, a supporting component and a rain shielding mechanism, wherein the placing seat and the fixing seat are symmetrically connected to the bulk grain funnel body, the driving motor I is connected to the fixing seat, the rotating seat is rotationally connected to the fixing seat, a rotating shaft of the rotating seat is connected with an output shaft of the driving motor I, two telescopic pipes are respectively placed on the two placing seats, the end parts of the telescopic pipes are rotationally connected with the rotating seat, the air cylinder is rotationally connected to the rotating seat, a telescopic rod of the air cylinder is rotationally connected with the bottom surface of the telescopic pipe, the inserting rod is connected to the end part of one telescopic pipe, a round hole matched with the inserting rod is formed in the end part of the other telescopic pipe, and the supporting component and the rain shielding mechanism are arranged on the bulk grain funnel body.
