Description

The invention relates to transporting devices and can be used for receiving, transporting, storing with active ventilation and mechanized unloading of grain materials.

Known aerodynamic conveyor [1], containing a conveying channel communicated with a source of compressed air, an air distribution channel and installed between them an air-permeable partition with a device located under it to cover its flow section, made in the form of installed with the ability to move along the last flexible tape, fixed by one the end on the side of the compressed air supply and having a length greater than the length of the air-permeable partition.

Disadvantages of the well-known aerodynamic conveyor:

1. Low functionality, the device is capable of performing only one operation - material unloading.

2. It is impossible to control the speed of movement of the transported material.

Known aerodynamic conveyor [2], containing a fan, an air supply pipe and an air supply channel, a louver partition made of several sequentially connected sections with varying degrees of louvers opening in adjacent sections, a mechanism for changing the angle of inclination of the louvers, setting them to the optimal position autonomously during unloading and interlocked during transportation, as well as a transport channel with an unloading window and a latch.

Disadvantages of the well-known aerodynamic conveyor:

1. The angle of exit of air jets is regulated within narrow limits.

2. Low functionality: serves only for unloading material or transporting it.

3. Due to the impossibility of controlling the speed of material movement, the device is not very suitable for transporting grain.

4. Depending on the angle of rotation of the plates, the distance between them changes, which entails a difference in the parameters of the air flow at the outlet of the air distribution grille, and possibly the ingress of particles of the transported material between the plates, which can lead to clogging.

Known aerodynamic conveyor [3], taken as a prototype, containing a fan, a conveying channel with an unloading window and a valve, an air distribution channel and an air distribution partition installed between the air distribution channel and the unloading window, made of several sections connected in series, controlled by a mechanism for changing the exit angle air jets, and the air distribution partition is made in the form of slot nozzles with the possibility of their rotation within 0 ° -180 °, and the mechanism for changing the angle of inclination of the slots of the nozzles is made in the form of rods rigidly fixed on one side to the axes of the slot nozzles, and on the other - to the leash, with the possibility of rotation, while the rod is made L-shaped, at both ends of it there is a thread, and on the middle rods of each section an arrow is rigidly fixed, combined with a graduated sector rigidly attached to the leash.

Disadvantages of the well-known aerodynamic conveyor:

1. Unloading of the transported grain material between the nozzles.

2. Limitation on the size of the processed grain material.

The objectives of the invention are:

1. Improving the performance of the aerodynamic conveyor.

2. Possibility of processing the processed grain material having different sizes.

The task is achieved by the fact that an aerodynamic conveyor containing a fan communicating through an air inlet pipe with a common casing, in which a conveying channel with an unloading window and a gate valve, an air distribution channel and an air distribution partition installed between the air distribution channel and the conveying channel, made in the form of slot nozzles, are located, an adjusting mechanism that allows you to change the angle of inclination of the casing, where upper and lower sieves touching each other are installed above the air distribution partition with the possibility of moving them relative to each other, while the sizes of the sieve openings change when they move.

The presence of adjoining upper and lower sieves above the nozzles prevents unloading and stagnation of the transported grain material between them, and the ability to adjust the size of the through holes in the adjoining upper and lower sieves allows processing grain material of different crops.

Figure 1 shows an aerodynamic conveyor; in fig. 2 - a fragment of the upper and lower sieves along arrow A in FIG. one; in fig. 3 - view B in Fig. 2.

The aerodynamic conveyor contains a fan 1 communicating through an air supply pipe 2 (for example, made of a corrugated pipe) with a common casing 3, in which a transport channel 4 with an unloading window 5 and a valve 6 are located, an air distribution channel 7 and an air distribution channel installed between the air distribution channel 7 and the transport channel 4 partition 8, made in the form of slotted nozzles 9. Above the air distribution partition 8, the upper 10 and lower 11 sieves touching each other are installed with the possibility of moving them relative to each other, while the sizes of the openings of the sieves change during their movement. The aerodynamic conveyor contains an adjusting mechanism 12 that allows you to change the angle of inclination of the casing 3.

The aerodynamic conveyor works as follows.

When the fan 1 is turned on, the air through the air supply pipe 2 enters the air distribution channel 7 and enters the conveying channel 4 through the air distribution baffle 8 and the holes in the contacting upper 10 and lower 11 sieves, and sets the grain material in motion. With the help of the adjusting mechanism 12, the angle of inclination of the casing 3 is changed, and accordingly the speed of movement and the process of active ventilation of the grain material. Grain material is unloaded at the end of the transport channel 4 into the unloading window 5.

The presence of the upper 10 and lower 11 sieves in contact with each other above the nozzles 9 prevents unloading and stagnation of the transported grain material between them, and the ability to adjust the size of the through holes in the contacting upper 10 and lower 11 sieves allows processing grain material of different crops.
