Description

Linen belt pick-up

The invention relates to agriculture and can be used for harvesting fiber flax.

Known machine for harvesting fiber flax [1], containing mounted on a rotary frame picking device with a copying wheel, behind which there are a device for straightening the flax tape, a device for separating boxes from stems and other working bodies.

Known pick-up-wrapper of flax belts [2], containing a pick-up device, a 90 ° cross wrapping conveyor, made of two contacting belts to form a wrapping stream, a conveyor located at an angle to it for transferring stems to a spread and a hammer, mounted on the lower side of the latter conveyor. The specified working bodies are assembled on an additional rotary frame, which is connected by means of a hinge to the main frame of a wheel-driven machine. A spreading board serves to spread the stems into a tape on the field. A hydraulic cylinder is used to transfer the technological elements located on the swing frame to the transport position.

A common disadvantage of the known fiber flax harvesting machines and the pick-up-wrapping machine is that the additional frame with the pick-up device installed on it, the wrapping conveyor and other working bodies has a significant mass, the inertial force of which in the working position prevents its angular oscillations relative to the hinge during the process of copying microroughnesses of the surface of the field by the copying wheel. The connection of the hydraulic cylinder with the additional frame has only one degree of freedom, which also complicates this process due to the resistance of the working fluid in the cavities of the hydraulic cylinder. In this case, the indicated inertial force and the resistance of the hydraulic cylinder arising during the operation of the gauge wheel during movement along the microroughness of the field surface cause galloping of the pick-up apparatus without picking up plants or excessive deepening of the fingers of the pick-up drum into the soil with stops of the technological process due to an increase in resistance to the movement of the wrapping conveyor with slipping of his belts. As a result, yield losses in the form of unpicked plants increase, machine productivity decreases, wear increases and the resource of its parts decreases. In addition, excessive penetration of the pick drum fingers into the microroughness of the field causes an increase in the soil content in the wrapped tape of flax stalks, which is unacceptable.

The closest in technical essence and technical tasks to the proposed invention is a pick-up-wrapper [3], containing a pick-up device, a wrapping conveyor, a conveyor for transferring stems to a spread with a knot-hammer and a device for forced spreading of the tape of stems, mounted on a rotary frame, which is attached to the main frame with wheel travel. The swing frame is connected to the main frame with hinges. The pressure of the gauge wheel on the ground is controlled by the tension of the balance spring. A hydraulic cylinder is used to transfer the technological elements mounted on the swing frame to the transport position.

The disadvantage of the known pick-up-turner is that an additional working body is installed on the rotary frame in the form of a device for forced spreading of the tape of stalks, which further increases the mass of the rotary frame and the force of its inertia.

The technical problem of the present invention is to improve the efficiency of the pick-up-turners.

The technical problem posed is solved due to the fact that in the pick-up-wrapper of flax belts, containing a pick-up device, a wrapping conveyor, a conveyor for transferring stems to a spread with a knot-hammer and a device for forced spreading of a tape of stems, according to the proposed invention, a pick-up device with a wrapping conveyor is mounted on a pivot frame, which is hinged to the main frame, and is transferred to the transport position by a hydraulic cylinder connected to the swing frame by a pin and a bracket with a groove, and a conveyor for transferring stalks to the spread with a hammer hammer and a device for forced spreading of the stalk strips are installed on the main frame of the pick-up -turner.

The positive technical result consists in increasing the collection of products, increasing the productivity of the pick-up-wrapper, the resource of its parts and reducing the soil content in the wrapped tape of flax stalks. The result is achieved due to a more accurate copying of the microroughness of the field surface by the pick-up wheel by the pick-up device by reducing the inertia force of the rotary frame of the pick-up-turner and eliminating the resistance of the hydraulic cylinder, which prevents angular oscillations of the said frame in its working position relative to the hinges. The resistance of the hydraulic cylinder is eliminated due to the free movement of its finger along the groove of the swing frame bracket in the working position.

With the proposed version of the pick-up-turner of flax belts, when its pick-up device with a wrapping conveyor is mounted on a swivel frame, which is connected with hinges to the main frame, and is transferred to the transport position by a hydraulic cylinder connected to the swivel frame by a pin and an arm with a groove, and the conveyor for transfer of stalks to the spreading with a hammer hammer and a device for forced spreading of the stalk tapes are installed on the main frame of the pick-up-wrapper, increasing the collection of products, increasing the productivity of the pick-up-wrapping, the resource of its parts and reducing the soil content in the wrapped tape of flax stalks due to the fact that the force of inertia of the swing frame has been significantly reduced and the resistance of the hydraulic cylinder to its angular oscillations in the working position relative to the hinges has been eliminated. Thus, the gage wheel of the pick-up device will more accurately copy all the microroughnesses of the field surface without galloping the rotary frame or excessive deepening of the pick-up drum fingers into the soil, which will lead to an increase in the cleanliness of picking plants from the surface of the field, a reduction in stoppages of the technological process, and an increase in the resource of parts of the pick-turner. and reducing the soil content of the wrapped tape of flax stalks.

The invention is illustrated in the drawings.

- In FIG. 1 shows a diagram of the proposed pick-up-wrapper of flax belts, side view;

- in Fig. 2 shows view A in FIG. 1;

- in Fig. 3 shows view B in FIG. 1.

The pick-up-wrapper of flax belts contains a pick-up device 12, a wrapping conveyor 9, a conveyor 7 for transferring the stems to the spread with a knot-hammer, a device 15 for forced spreading of the tape of the stems. In this case, the pick-up device 12 and the wrapping conveyor 9 are mounted on the rotary frame 6, and the conveyor 7 for transferring the stems to the spreading with a knot-hammer and the device 15 for forced spreading of the tape of the stems are installed on the main frame 14 of the pick-up-wrapper having a wheel travel 13.

The pick-up device 12 consists of a pick-up drum 10 and a copying wheel 11.

The wrapping conveyor 9 is represented by belts pressed against one another and crossed by 90 °.

The conveyor 7 for transferring the stems to the spreading with a tamping machine contains conveying 8 and 1 tamping conveyors.

The device 15 for forced spreading includes a shield in which a slot is cut out in the middle part along the radius of the circle. The working edge of the endless belt located under the shield protrudes through the gap above the shield surface. There are projections on the working edge of the endless belt. An endless belt goes around a system of pulleys and rollers under the shield. Above the shield is a system for pressing the stem mass to the edge of the endless belt.

For separate harvesting, the proposed pick-up-wrapper can be installed on the pick-up-stripper. In this case, behind the conveyor 7 for transferring the stems to the spread, an apparatus is installed to separate the seed part of the crop from the stems (not indicated in the drawings).

The swing frame 6 is connected to the main frame 14 by means of hinges 2. The pressure of the gauge wheel 11 on the ground is regulated by the tension of the balancing spring 3. To transfer the technological elements mounted on the swing frame 6 from the working position to the transport position, the hydraulic cylinder 4 is used. The hydraulic cylinder 4 is connected to the swing frame 6 with a pin and bracket 5 with a groove. The groove in the bracket 5 provides freedom of movement of the rotary frame 6 in the working position relative to the pin of the hydraulic cylinder 4.

The pick-up-wrapper of flax belts works as follows. When performing the technological process, the machine operator directs the unit along the flax belt so that the center of the pickup drum 10 coincides with the middle of its width, and the top part of the belt is on the right side of the drum 10 along the tractor travel. The fingers of the drum 10 pick up the tape of the stalks from the surface of the field. The tips of the fingers of the pick-up drum during its operation describe trochoids, the lower points of which touch the surface of the field. The gauge wheel 11 rolls over the irregularities of the surface of the field, imparting its trajectory of movement in the vertical plane to the pick-up drum 10. In this case, the rotary frame 6 with the pick-up device 12 and the wrapping conveyor 9 placed on it makes angular oscillations around the hinges 2, and the hydraulic cylinder finger moves freely along the groove bracket 5. Due to the reduced mass of the swing frame and the freedom of its movement in the working position relative to the hydraulic cylinder pin, the ends of the pick-up fingers at the lower points of their trochoids will more accurately copy the microroughnesses of the field surface without galloping or excessive deepening with the selection of all plants without gaps.

Immediately after picking up the stems fall into the clamp between the belts of the wrapping conveyor 9. In the clamped state, moving from the picking drum 10, the tape is wrapped 90 °. At the exit from the wrapping conveyor 9, the flax belt changes its direction of movement towards the conveyor 7 to transfer the stalks to the spread with a hammer and is captured by the blades of the transporting conveyors 8. During the movement of the conveyors 8, the stalks slide down under the action of gravity in the direction of the inclination of the plane passing through the workers branches of the specified conveyors. And at this time, the working branch of the blocking conveyor 1, which performs oscillatory movements, strikes the butt of the stems, as a result of which their elongation in the belt decreases. After exiting the conveyor 7, the tape of stalks is carried away by the working edge of the moving endless belt of the device 15 for forced spreading and moves to the soil. For separate harvesting, the proposed pick-up-wrapper can be installed on the pick-up-stripper. In this case, the plant tape, after exiting the conveyor 7, will enter the apparatus for separating the seed part of the crop from the stems (not indicated in the drawings).

Thus, an increase in the collection of products, an increase in the productivity of the pick-up-wrapper, the resource of its parts and a decrease in the soil content in the wrapped tape of flax stalks will occur due to the fact that, due to the reduced mass of the rotary frame and the freedom of its movement in the working position relative to the hydraulic cylinder pin, the copying wheel of the pick-up device , and with it the ends of the picking fingers at the lower points of their trochoids, will more accurately copy the microroughness of the field surface without galloping or excessive deepening with the selection of all plants without gaps.
