Description

FIELD OF THE INVENTION The invention relates to agricultural machinery engineering and is associated primarily with threshing of cereals.

The purpose of the invention is to reduce grain losses when unwinding rolls.

Figure 1 presents the installation, General view; figure 2 is the same, top view; on fig.Z - section aa in figure 1; figure 4 - node I in figure 1; on fig.Z - node II on fig.Z.

The roll unwinding machine consists of a frame 1 with support wheels 2, which are connected to frame 1 by means of cranked pillars 3. The latter have the ability to rotate relative to frame 1. On the frame 1 there is a loading side 4, a rotating device 5, a woofer 6 and a fence 7 .

The loading board 4 is mounted in front of the frame 1 and consists of a tubular arm 8, which is mounted with the possibility of rotation at some angle relative to the frame 1 of the installation, floating fingers 9 fixed to the tubular arm 8 by means of the axes 10 floating fingers 9 of the hydraulic power cylinders 11, which are connected by means of pins 12 to frame 1 and tubular arm 8. Floating pins 9 have the ability to rotate at some angle relative to tubular arm 8.

I

The rotator 5 is mounted in the middle part of the frame 1 of the machine and consists of a conveyor 13. Underneath the conveyor 13 a cleaning beater 14 is installed. Behind the conveyor 13 there is a finger beater 15 which functions as a chopping device.

The rotary conveyor 13 contains the drive shaft 17, the drive shaft 17, the tension roller 18, the support rollers 19 on which the chain-slatted working (supporting) body 20 is mounted. On the slats 21 of the chain-slat conveyor 13, curved teeth are mounted with a certain step 22. Inside under the chain-slatted working body 20, oiiba drums 23, installed sludge poup van 17, and corresponding to the BeTCTBVicuime of the surface of the driven shaft 16, the t of the roller 18 n support

rollers 19, two endless rubber bands are mounted. 24. The braking force of the chain-slat conveyor 13 is transmitted by means of sprockets 25 fixed on the drive shaft 17. The upper branch of the rotary conveyor 13 has a slight inclination inside the machine, ensuring reliable fixation of the roll 26 during its unwinding. Cleaning the beater 14 is installed on the frame 1 of the machine under the lower branch of the rotating conveyor 13 and consists of a shaft 27 and

5 blades 28, which are rigidly fixed on the shaft 27 and, when rotated, pass with a small gap between the curved teeth 22 and the strips 21 of the lower branch of the rotating conveyor. The finger beater 15 is mounted on the frame 1 of the installation and consists of a shaft 29 on which cylindrical fingers 30 are fixed, and a casing 31 mounted also on the frame 1 of the installation. The Qi5 lindrical fingers 30 are placed on the shaft 29 radially in groups and, when moving, pass through the slots of the casing 31, and across the width of the group of fingers are located between the curved teeth 22, Shaft

Q 29 of the finger beater 15 is mounted for movement within certain limits in the vertical and horizontal directions.

Top-mounted device 6 is installed, leno on the frame 1 of the installation under the rotating conveyor 13 with some overlap in length by means of a drive shaft 32, on which the drive sprockets 33 and the drums are mounted

Q 34, and the driven shaft 35, which bends around the chain-slatted working body 36. Under the chain-slatted working body 36, two endless rubber bands 37 are placed on the drums 34 and the corresponding smooth surfaces of the home shaft 35. On the slats 38 of the chain-slider conveyor spring loaded grippers 39 are installed, which consist of figured plates 40 and mounted on slats 38 by means of axes of figured plates 41. Cylindrical springs 42 mounted on axes of figured plates 41, with some effort, press the stops of figured layer n splines 43 to the surface 38.

plates 41 counterclockwise. The magnitude of the deviation depends on the force applied to the figured plates of AO in horizontal direction. An anti-slide shield 44 is mounted above the top-lifting conveyor with a gap decreasing in length.

The fencing 7 of the unwinding machine consists of rollers 45 mounted on the frame 1 of the installation with the possibility of free rotation, the bottom 46 fixed in the lower part of the frame 1, and the rear part 47 of the installation frame 1, with which it is joined to the inclined Chamber 48 combine harvester. In the recess 49 of the bottom there is a device 50 for collecting and transporting the spilled pile, which consists of a screw 51 with one-sided winding, a scraper conveyor 52 and a distribution screw 53.

The installation works as follows.

The combine harvester pushes ahead the machine for unwinding the reels, which with its rear part 47 is rigidly attached to the inclined chamber 48 of the combine. The hydraulic distributor controlling the raising and lowering of the header of the combine harvester is in the Floating position. The support wheels 2 of the machine for unwinding rolls at the same time roll over the soil surface, providing the unit with copying of longitudinal unevenness of the floor and perceived vertical loads from the weight of the machine, the inclined chamber 48 and the roll 26 in the future. Crankshafts 3, turning relative to frame 1 when maneuvering, allow the unit to make small turns, protecting the machine attachment parts to the inclined chamber of the combine harvester from damage. The loading side 4 is in the lower position before the gripping of the rue 26. In so doing, the floating fingers 9 slide along the floor surface. After pushing the floating fingers 9 under the roll 26 from the side of the forming cyindric surface and reaching the front of the frame, the tubular arm 8 together with the fingers 9 fixed on it, on which

roll 26, rotates by some hijacking with hydraulic cylinders 1 1 and roll 26 smoothly rolls onto a slow-moving chain-slat conveyor 13 of the rotator 5. After the rollers 45 touch the fence 7, roll 26 starts rotation. The curved teeth 22 of the chain-slat conveyor 13 are initially pierced to a certain thickness by the roll 26 and are somewhat displaced in the bread mass, contributing to its rotation, and then when they reach the edge of the price-pressed conveyor 13 they turn around and rush down, dragging along layer of a certain thickness. This, in addition, contributes to the counter-movement of the cylindrical fingers 30 of the finger beater 15. The passage into the gap between the slats 21 of the chain-slat conveyor 13 and the casing 31 of the finger beater 15, the layer separated from the roll falls on the chain-slat conveyor of the phragm device 6, the speed of movement is spring-loaded grabs 39 which is higher than the supply of grain mass. The figured plates 40 of the spring-loaded grippers 39, which occupy a vertical position in relation to the slats 38 of the chain-slat conveyor, interact with the incoming flow of grain mass, push it out from under the lower branch of the rotating conveyor 13 and, pressing it against the opposing surface, pull in the direction of the inclined chamber 48 combine harvester. The resulting axial forces constantly vary in magnitude, overcoming the resistance of the coil springs 42, deflect the shaped plates 40 from the vertical position. The flow rate of the grain mass increases on average, and its density in the cross section decreases. This is also facilitated by a decreasing gap between the opposing flap 44 and the chain-slat conveyor of the topping device 6. A certain amount of grain mass despite a significant overlap still remains on the lower branch of the rotating conveyor 13. The cleaning beater 14 has blades 28 which move to the same side then

and the tooth of the lower branch of the rotating conveyor 13, but with greater speed, removes the remnants of the grain mass. The heap spilled as a result of the unwinding of the roll 26 accumulates in the recess of the bottom and is transported by the screw 51, the scraper conveyor 52 and the distribution screw 53. into the inclined chamber 48 of the combine harvester.

The endless rubber bands 24 and 37 transport the main stream of the spilled during the unwinding of the pile roll into the inclined chamber of the combine harvester, thereby preventing overloading of the collection and transportation device 50 of the spilled pile.
