Description

The invention relates to agricultural machinery, in particular, to harvesting and harvesting machines.

The purpose of the invention is to increase reliability by automatically maintaining a predetermined gap between the discharge pipe and the surface of the affinity transport.

The drawing shows the unloading pipeline agricultural harvester.

The discharge pipeline contains a vertical pipe 1 with a transporting element 2 mounted on it. At the end of the transporting element 2, a telescopic extension 3 with an elastic tip 4 is installed in guides. The tip 4 in the form of a flexible shell has an internal 5 and an external 6 wall forming a closed cavity filled with through the nipple 7 by the gaseous medium under the pressure particle, so the latter is lowered under the action of an unbalanced gravity force up to the stop of the end face of the height limiter 11 into the bottom of the transport platform dstva that

5 provides the specified position of the outlet and the maximum safety of products. As the product is unloaded, the level of its surface in the vehicle body increases, which affects the height limiter and raises the extender 3. When considering the interaction of the product surface and the lower part 13 of the height limiter, it is necessary to have that during the unloading process on the go, the mutual changes continuously horizontal position of the harvester and the vehicle. Products located in the vehicle body exert a force on the lower part 13 of the height limiter. This forceful effect is axial and bonium. Telescopic extension 3 install- 20 directions. The first tends to be lined up on the conveying element 2 with the possibility of moving along guides made, for example, in the form of angles 8, along which the rollers 9 roll, to restrain the stopper with the extension 3, and the second tends to bend the lower part 13 of the stopper. The lower part 13 of the restrictor, being filled with a gaseous medium under

tanovlennye on the extension 3 in the notches-pressure, 5 pressure, has elasticity, therefore

means of axles. On the telescopic extension 3 in brackets 10 a height limiter 11 is installed with the possibility of changing position and fixation by means of clamp 12. The lower part 13 of the height limiter is designed as an elastic hollow cylinder closed from the bottom butt with a reinforcing element 14 in the form of a spatial spiral. The lower part 13 of the limiter with an open end is sealed to the open end of the upper part and forms with it a closed cavity filled through the nipple 15 with a gaseous medium under pressure. Most of the force of the telescopic extension 3 is balanced by a counterweight 16 connected to it by means of a flexible link 17, made, for example, in the form of a cable, enveloping the blocks 18. The flexible link 17 is also connected to the control element 19. The counterweight 16 is mounted on the vertical part of the conveying element and can be moved along the guides 20 by means of rollers 21 arranged similarly to the rollers and guides of the extension 3. The telescopic extension 3 can also be balanced in another way, for example by means of a hydraulic actuator containing a hydraulic cylinder and hydraulic accumulators torus

The export pipeline agricultural harvester works as follows.

The discharge pipe is brought into position with the aid of the control member 19 by setting the telescopic extension 3 to the predetermined position. Counterweight 16 balances the strength of the body of the telescopic extension 3 only

when it is bent under the action of a lateral force, an additional axial force arises, also tending to lift the extension 3. As a result of this interaction, the telescopic extension 3 rises

30 moves up along the guides 8 as the level of the material surface increases in the vehicle body, and the counterweight 16 goes down. In the case of vehicle interaction with tip 4, the latter, due to elasticity, is tilted 35 under the action of lateral force, and the resulting axial force ensures the telescopic extension 3 to lift with tip 4 along guide 8. After the vehicle with tip 4 stops interacting, due to elasticity, it acquires the same shape and the extension 3 is returned to its original position by gravity. When relocating the harvesting machine extension 3 with tip 4 and limiter 11

45 heights are raised to the transport position by means of the control element 19. During operation, depending on the operating conditions (type of material, its condition, weather conditions, etc.), the specified height of the outlet opening is possible

50 is changed by moving the height limiter 11 in the brackets 10 and fixing it by means of the clamp 12.

Claims (2)

1. The unloading pipeline of an agricultural harvesting machine containing mounted on a vertical pipe partly, therefore, the latter is lowered under the action of an unbalanced body weight to the stop of the end face of the height limiter 11 into the bottom of the vehicle platform, which 5 provides the specified position of the outlet and the maximum safety of products. As the product is unloaded, the level of its surface in the vehicle body increases, which affects the height limiter and raises the extender 3. When considering the interaction of the product surface and the lower part 13 of the height limiter, it is necessary to have that during the unloading process on the go, the mutual changes continuously horizontal position of the harvester and the vehicle. Products located in the vehicle body exert a force on the lower part 13 of the height limiter. This force effect has axial and lateral directions. The first tends to a horseshoe direction. The first tends to raise the stopper along with the extension 3, and the second tends to bend the lower part 13 of the stopper. The lower part 13 of the restrictor, being filled with a gaseous medium under pressure, has elasticity, therefore -, 5 pressure, has elasticity, therefore when it is bent under the action of a lateral force, an additional axial force arises, also tending to lift the extension 3. As a result of this interaction, the telescopic extension 3 rises 30 moves up along the guides 8 as the level of the material surface increases in the vehicle body, and the counterweight 16 goes down. In the case of vehicle interaction with tip 4, the latter, due to elasticity, is tilted 35 under the action of lateral force, and the resulting axial force ensures the telescopic extension 3 to lift with tip 4 along guide 8. After the vehicle with tip 4 ceases to interact, due to elasticity, the former forms and the extension 3 is returned to its original position by gravity. When relocating the harvesting machine extension 3 with tip 4 and limiter 11 5 heights are raised to the transport position with the aid of the control element 19. During operation, depending on the operating conditions (type of material, its condition, weather conditions, etc.), the specified height of the outlet opening is possible 0 is changed by moving the height limiter 11 in the brackets 10 and locking it by means of the clamp 12. 0 Invention Formula 1.
