technical field

The invention belongs to the field of grain storage, and in particular relates to a combined conveying particle discharger for conveying bulk grains.

Background technique

In recent years, with the continuous progress and development of modern science and technology, bulk grain outbound operations are facing several problems: First, due to the transformation of grain from packaging transportation to bulk storage, bulk transportation, bulk, and bulk unloading "four scattered" transportation The storage capacity of bulk grains is also expanding year by year, which puts a certain pressure on the existing bulk grain equipment; secondly, due to the changes in the market environment, the grain delivery season has undergone fundamental changes, and the grain output in high temperature seasons The situation tends to be frequent, which brings serious safety hazards to the grain preservation work; third, the grain stored in the warehouse is gradually being sold in the form of electronic auctions, so the issue of the timeliness of grain leaving the warehouse after the auction is particularly important; the fourth In order to ensure the safety of their grain, reduce operating costs, and speed up the efficiency of bulk grain delivery; fifth, the current grain picking operations mainly use pneumatic conveying equipment and manual operations. The form, its high energy consumption, low efficiency, high cost of operation, high labor intensity, does not meet the current energy conservation and emission reduction requirements.

At present, bulk grain can be collected by vacuum suction. This method will use a grain suction machine (pneumatic conveyor). other impurities. In addition, in order to provide a good storage environment for grain storage, facilities such as ventilation cages and underground bedding are installed on the warehouse floor, but they become obstacles during the grain collection process. If they are also sucked into the machine, the consequences will be disastrous. Finally, the grain has a certain broken rate requirement during the absorption process and cannot be destroyed too much.

In view of the characteristics of the above bulk grain, bulk grain out of the warehouse is facing a revolution.

The grain particles enter the shovel hopper 7 through the feeding port 77, and the rotating shaft 71 rotates at the same time, driving two sets of helical blade groups 72, 73 to work, and the grain particles fall between the blades and are transmitted along the rotating shaft 71. Because the direction of rotation of the two groups of helical blades is opposite, the conveying direction of the grain particles is to gather from both sides to the middle, and finally arrives at the concentration port 74 in the middle. Conveyor belt 3 is just below gathering mouth 74, and grain grain enters on the conveyer belt 3 subsequently. According to the harsh working environment of the bulk grain warehouse and the characteristics of bulk grain impurities, the present invention adopts a two-way feeding method, and the outlet (that is, the centralized port) is set in the middle. Fall together on the conveyor belt 3. The work requirements of general suction machines are quite high, and it is difficult to adapt to the dusty environment. However, if a one-way feeding method is adopted, since the outlet is located on one side, the impurity will easily block the outlet. Generally, the rotating shaft is covered with hemp rope. If the impurity is wrapped around the hemp rope, it will affect the work and even burn out the motor. Please see the following table in addition, compared with the suction machine and the one-way screw machine, the output of the present invention is greatly improved, and the energy consumption is very low.
