Description

Grain is loaded automatic handling device in bulk

The utility model relates to the technical field of grain mechanism for conveying and loading, and particularly grain is loaded automatic handling device in bulk.

At present, main packed form and the bulk form that adopts of China grain transportation, problem such as packed form exists the loading and unloading charge height, and alongshoreman's labour intensity is big, therefore, packed transportation mode has not met international trend, is replaced by bulk form gradually.The transportation mode in bulk of country's employing at present is: adopt belt transportation machinery to wait other machineries with the Bulk Grain in the silo, in the tank body top hole tank filling of tank car, during unloading, also adopt belt transportation machinery that the grain in the jar is put in storage, the problem that this transportation transportation tank car in bulk exists is: 1., since the cost height that handling equipment drop into can only adapt to large granary and use; 2., the grain loading and unloading time are subjected to weather effect, rainy day, snow day can't load and unload; 3., used air sealer, grain breakage rate height, power consumption increases, and has increased the weight of transport trolley, oil consumption is risen, and install difficult.

The purpose of this utility model provides on the transportation meanss such as a kind of installable automobile, train, and low cost of manufacture, grain breakage rate are low, and grain that can the all-weather operation is loaded automatic handling device in bulk, to solve the weak point that prior art exists.

In order to realize the foregoing invention purpose, the technical scheme that the utility model adopted is: grain is loaded automatic handling device in bulk, comprise that a closed Cargo tank and is contained in closed Cargo tank bottom, the hydraulic efficiency elevation structure that is used for jacking envelope formula container, it also comprises a high pressure positive blower, the air outlet of high pressure positive blower is equipped with threeway, and threeway is leaded up to valve and is connected to and blows the grain flexible pipe, the unloading pipe that is connected in the closed Cargo tank bottom with blow the grain soft pipe connection; Another road of threeway is connected to the equilibrium of pressure blowdown pipe, and the equilibrium of pressure blowdown pipe is communicated with ventilation inlet on the closed Cargo tank, is provided with by-pass valve control in addition on the equilibrium of pressure blowdown pipe; The ventilation inlet of high pressure positive blower is connected with an exhaust column, and exhaust column is communicated with suction opeing on the closed Cargo tank, and is provided with a valve on exhaust column, and is connected with the air intake arm of a band valve; On closed Cargo tank, be connected with one and inhale the grain flexible pipe by valve.

In order to protect environment, the further improved technical scheme of the utility model is: be provided with duct cyclone between the suction opeing on described exhaust column and the closed Cargo tank.

In order to realize goal of the invention of the present utility model better, the further improved technical scheme of the utility model is: the described diameter that blows the grain flexible pipe should be greater than the diameter of equilibrium of pressure blowdown pipe.

Principle of work of the present utility model is: with the utility model integral installation on automobile, the power of high pressure positive blower and hydraulic efficiency elevation structure relies on automotive engine to supply with, when the Bulk Grain entrucking, valve on shutoff pressure balance blowdown pipe and the air intake arm, and close unloading pipe on the closed Cargo tank, open to inhale valve and the valve on the exhaust column on the grain flexible pipe and blow valve on the grain flexible pipe, start high pressure positive blower, at this moment the air in the closed Cargo tank is drawn out of, make and form negative pressure in the closed Cargo tank, like this, inhaling the grain flexible pipe just can inhale the Bulk Grain in the warehouse in people's closed Cargo tank, at this moment, the effect of duct cyclone mainly is to remove that to enter container with material airborne, and with the dust and other impurities of the distinguished and admirable extraction of exhausting.When Bulk Grain is unloaded, start hydraulic efficiency elevation structure, closed Cargo tank is tilted about 35 °, and close the valve inhaled on the grain flexible pipe and the valve on the exhaust column, the valve on response pressure balance blowdown pipe and the air intake arm and blow valve on the grain flexible pipe starts high pressure positive blower, the high velocity air that high pressure positive blower blows out, by threeway, the one tunnel through the supercharging in closed Cargo tank of equilibrium of pressure blowdown pipe, and another road will enter the Bulk Grain that blows in the grain flexible pipe by the unloading pipe and blow out.Or open the container unloading mouth of pipe, utilize the gravity flow angle unloading of Bulk Grain.Because the utility model has adopted technical scheme as above, compares than prior art, has following advantage: 1, improved the handling speed of Bulk Grain, and can realize the loading and unloading of all-weather; 2, simple in structure, low cost of manufacture is installed on the automobile, can carry out loading and unloading operation whenever and wherever possible, has improved plot ratio effectively, has reduced the cost of Bulk Grain transportation per ton.3, reduce breakage rate in the Bulk Grain handling process effectively, improved grain quality.4, do not use packing material, saved the packing material expense.The utility model is applicable to granulate materials such as all kinds of cereal of loading and unloading, corn, soybean, oily bud seed, jowar, is a kind of desirable Bulk Grain handler.
