(5) ELEVATOR TO FEED BULK ROOTS

   . 1 - The invention relates to

mechanization of livestock and fodder production, in particular, to devices for transporting bulk feed.

A grain elevator for conveying bulk materials is known, comprising a driven and driving drum, a drum bending body, a working tool to which buckets are attached without a bottom C O

A disadvantage of the known device is low productivity in the transportation of bulk feed, including flour components: crushed grain, bran, grass flour, sweetmeal flour, micro additives such as crushed shell rock, etc. This is due to the increased adhesion of the flour components to the walls of the buckets, as a result of which the latter do not have time to empty when rounding the upper drum and some parts of the material adhering to the walls are involved in multiple unproductive transportation along a closed contour.

Also known is an elevator for transporting liquid and bulk materials, comprising upper and lower drums, an endless transporting working body, made in the form of a spiral attached to the drum bend envelope of the carrier web 21.

Performance specified

10, the device is low due to the insufficient wrap angle of the upper drum and the difficulty of unloading conditions, as well as insufficient cohesive forces of the transported material with the inner surface of the helix during transportation in the vertical section.

The purpose of the invention is to increase the productivity during the transportation of flour feeds.

The goal is achieved by the fact that the elevator is equipped with a roller mounted under the upper drum to preload

the supporting web, and an additional helix installed inside the main helix.

Figure 1 shows the elevator for feeding bulk feed, side view) in figure 2 - the same, rear view; on fig.Z - section aa in figure 2,

The device contains the leading upper and slave bottom drums 1 and 2, respectively, mounted on frame 3. The drums t and 2 round the continuous supporting web, to which is attached an endless transporting working body, made in the form of the main helix 5 within which an additional one is installed. helix 6. An additional helix increases the adhesion forces of the transported material to the inner surface and helps to keep it in the vertical transport section.

Under the drum 1, a roller 7 is installed, which serves to press the carrier web to the drum, to increase the angle of its circumference and thereby to facilitate the conditions for unloading the material.

Several pairs of spirals 5 and 6 can be fixed on the carrier sheet 4. In this case, it is advisable to install one roller 7 located between them on two pairs of spirals.

To load the bulk feed, the elevator has a receiving bin 8. The discharge chute 9 is installed in the discharge area. To prevent spraying of the feed, the elevator is equipped with a casing 10 with a visor 11 pivotally attached to it. ). The device is driven by a gearmotor 12.

The device works as follows.

Bulk feed is loaded into the hopper 8 and gearmotor 12 is turned on. The coils of the main and auxiliary coils 5 and 6, skirting the BOTTOM drum 2, open and grab the feed. The passage to the straight vertical section of the turns of the spirals is closed and the feed is transported upwards to the discharge zone. Uninterrupted transportation is ensured by a constant feed intake to the working bodies and the creation of a permanent backwater. In the unloading zone of the spiral 5 and 6, the upper drum 1 goes around, the turns re-open and the feed is thrown out by the centrifugal force towards the visor 11 and, reflecting from it,

enters the tray 9, Roller 7, increasing the active unloading zone, allows working at higher speeds of movement of the working body, and the productivity of the material transport process increases. The working body is completely free from flour-like bulk feeds due to the vibration of the turns of the spirals when the device is operating in the discharge zone.

Using the proposed elevator allows to increase the production. the feed flow rate of dry flour type cows, for example, ground grain, grass meal, flour meal, etc., to a level that meets modern requirements for processing and feed preparation lines.
