SUBSTANCE: harvesting fiber flax. The puller contains dividers, a crankcase, two direct-flow pulling devices located under the crankcase and consisting of sections with belts that wrap around pulleys and rollers, converging in pairs, doubling-turning-output devices, as well as a draft tongue. The draft tongue is located between two pulling devices above the crankcase, fixed to the crankcase through a rotary gearbox located in the middle of the crankcase. On the other hand, the draft tongue is connected to the power tool through the second traverse gearbox.

Description

Known flax puller [1], containing a frame with a tow hitch, based on two wheels, and mounted on it pulling device, transverse conveyor and output device in the form of spreading table. This puller is not a direct-flow machine, it has low technological reliability and low productivity.

Known flax pullers U - 22, [2, pp. 36-38], containing a pulling apparatus, consisting of sections with belts, enveloping pulleys and rollers, converging in pairs, and placed behind the sections doubling-wrapping and spreading belt-roller devices. This puller is a self-propelled direct-flow machine. The specified puller during operation forms two tapes. These machines have high technological reliability both on normal and laid flax, and high productivity.

The disadvantage of the puller is the complexity of the design, large dimensions, weight and energy intensity, high cost and low efficiency of self-propelled machines in comparison with trailed ones.

The closest in technical essence and set technical tasks to the proposed one is a flax puller [3] containing a frame with a crankcase mounted on it, on which a direct-flow pulling apparatus is placed, consisting of sections with belts that wrap around pulleys and rollers, converging in pairs and an output device placed behind the sections. The puller can work as a trailer through a drawbar, aggregated with a power tool, or as a mounted one directly hung on a power tool. The positive qualities include direct flow, the ability to work both trailed and mounted.

The main drawback of the puller is that the puller is directed upwards at an angle of about 45 degrees to the horizon, and the puller has a straight line with two belts, which are also located at about 80 degrees to the doubler-wrapper. When the tape passes from the wrapper to the spreader, there is a sharp change in the movement of the tape. The stems of the plant at the transition point are not clamped by anything, which leads to clogs, distortions and stretching of the stems in the tape.

The objective of the invention is to improve the performance of the flax puller, to increase the technological reliability and productivity of the direct-flow puller, composed of a power tool (tractor) and this machine.

The problem is solved due to the fact that in the flax puller, containing the crankcase and two pulling devices mounted on it and placed under the crankcase, consisting of sections with belts that go around the pulleys on it according to the direct-flow scheme by technological bodies, the crankcase is connected to a drawbar located in the middle between the two lifting devices above the crankcase, while the drawbar has the ability to turn on the crankcase gearbox from the hydraulic cylinders, and the clutch gearbox breathed with energy.

A positive technical result is achieved due to the fact that the proposed puller will have two direct-flow pulling devices and two doubling wrapping - output devices. This design will provide an increase in the speed of the unit, technological reliability and its performance.

The pulling device used in the proposed machine is similar to the device with converging pairs of belts, the U-22 pulling device, which operates at speeds up to 20 mph [3, p. 55]. The absence of an output device will eliminate clogs, distortions and stretching of the stems in the tape. The ability to turn the drawbar will allow the power tool to work both on the left and on the right in the direction of travel. A trailed double-row puller will be several times lighter and cheaper than a self-propelled puller, and the performance will be the same. Thus, the unit, composed of a power tool (tractor) and the proposed trailed flax puller, will be more economical in comparison with a self-propelled flax puller.

The invention is illustrated in the drawings. In FIG. 1 shows a diagram of a flax puller, side view and in Fig. 2 - the same, view along arrow A in Fig. 1.

The flax puller contains dividers 1, two pulling devices 2, two double-turning-output devices 3 mounted on the crankcase 4 behind the pulling device 2. Pulling devices 2 consist of sections 5, including belts 6, enveloping pulling 7 and driving 8 pulleys, as well as rollers. The doubling turning-out device 3 consists of two belts - the lower 9 and the upper 10. Gears are planted on the shafts in the crankcase 4, which serve to transmit torque to the driving pulleys of the pulling belts 6 and the double turning-out device 3. oh 12, which are placed directly in the drawbar 13. The drawbar 13 consists of two swivel gearboxes incoming 14 and outgoing 15, connected to each other through a connection 16. The turn of the drawbar is carried out by hydraulic cylinders 17, which are connected to the hydraulic system of the power tool. Drawbar rotation is limited by hydraulic cylinders. Along the edges of the crankcase there are support wheels 18, which, due to the hydraulic cylinders 19, move from the transport position to the working position.

The proposed terebilka works as follows. During the execution of the technological process, the puller is transferred to the working position, the drawbar 13 is turned in the required direction, the supporting wheels 18 are transferred to the working position.

When the puller moves across the field, the dividers 1 divide the flax stem into strips and bring the stems of the plant to the pulling devices 2, in which the pulling belts 6 and pulleys 7 clamp the plant stems with their surfaces and pull them out when the machine moves forward. Behind the pulleys 7, the belts 6 converge in pairs and bring the strip of pulled plants into one stream. The belts 6 transport the flax tape to the exit from the section of the pulling apparatus 2. After leaving the pulling apparatus 2, the flow of plants is formed into one stream (tape) of flax by a double-turning-removing device 3. The flow of plants is captured by two belts 9 and 10 and rotates the tape by 90 degrees, the tape from the vertical position passes into the horizontal, then the tape passes along the bars to the soil.
