Description

The utility model relates to agricultural machinery and can be used in flax harvesting machines.

Flax harvester cleaning devices are known (USSR AS No. 175769, class A 01 D 45/06, 1962; USSR AS No. 1561880, class 5 A 01 D 45/06, 1988; USSR AS No. 1704679, class 5 A 01 D 45/06, 1990; AS USSR No. 1692349, class 5 A 01 D 45/06, 1990; flax harvesters LKV-4T, LK-4T. Operation manual / Uizd. Red Hill, 1977, pp. 16-24; AS USSR No. 165022, class A 01 D 45/06, 1962, prototype) containing a clamping conveyor, a tow chamber with inlet and outlet windows and a combing drum with ridges, mounted on crank shafts located at an equal distance from each other along the periphery of the drum disks. All of the above combing devices are made of four ridges.

When sowing seed bolls of long-stalked flax and medium-length flax, which occupies the main part of the crops, the layer of carved stems falls simultaneously under the influence of two ridges, one of which has not yet had time to completely comb the tops of the stems, and the other has already entered the layer stretched in front by the leading ridge clamping conveyor. This leads to additional damage and skew of the stems, their cracking and cutting, additional friction against the teeth from the action of the second ridge coming from the back behind the strings stretched by it, which inevitably leads to an increased stalk withdrawal into confusion.

The problem solved by the utility model is to reduce damage to flax stalks and their withdrawal into confusion in the process of stripping seed bolls.

The problem is solved by supplying the drum in a stripper of a flax harvester containing a clamping conveyor, a tow chamber with inlet and outlet windows and a stripping drum with ridges mounted on crank shafts located at equal distance from each other along the periphery of the drum disks with three ridges.

The number of ridges is determined from the condition that only one ridge should be in the stalk layer. In this case, there will be a minimum of effort pulling the stems out of the clamp in the clamping device. Damage to the stems and their retreat into confusion will also be minimal. In a layer of long-stalked flax (not more than 10% of crops), there can be two ridges at the same time; however, in this case, the simultaneous effect of two ridges on the stalk layer is excluded, since the comb included in the layer begins to sap seed bolls only when leaving the layer in front of the moving drum ridge. The utility model is illustrated by drawings.

In Fig.1 shows a stripping device flax harvesting machine, side view; figure 2 is the same, a section aa in figure 1.

The stripping device of the flax harvester comprises a clamping conveyor 1, a towing chamber 2 with an entrance window 3 and a stalk exit window 4, a combing drum installed in the towing chamber 2 in the form of a shaft 5 with two disks 6, at the periphery of which are equally spaced in bearings three crank shafts 7 with Vis ridges 9 and 10 for transporting tow products, and a conveyor belt 11 are placed from each other.

The blade 10, located in the plane of the ridge 8, serves to prevent windings on the ridge 8, and installed at an angle to the blade 10

the blade 9 of the next ridge 8 is designed to pick up tow products and transfer them through the drum to the heap conveyor 11.

The cranks 12 of the shafts 7 of the ridges 8 are pivotally connected to the guide disc 13, the eccentric disc 6 of the drum, due to which the teeth of the combing ridges 8, rotating with the drum, maintain a constant direction. To change the inclination of the ridges 8, an eccentric 14 is placed on the shaft 5 of the stripping drum, connected to the guide disk 13, which is connected through the crank 12 to the axes 7 of the ridges 8. The screw mechanism 15 is pivotally connected to the eccentric 14.

The cleaning device of the flax harvester operates as follows.

Before starting work with the screw mechanism 15, the ridges 8 of the stripping drum are installed in a predetermined position. Depending on the length of the stalks being combed, the teeth of the ridges 8, by turning the eccentric 14, the guide disk 13 and the cranks 12 by the screw mechanism 15, approach or, conversely, move away from the clamping conveyor 1.

The stems clamped by the clamping conveyor 1 are moved through the tow bed 2, where they are affected by the ridges 8 of the stripping drum, as a result of which the seed boxes are separated from the stems. Since the number of ridges is such that there is only one ridge in the combed layer, the force pulling the stems out of the clamp in the clamping conveyor 1 is minimal. Therefore, damage to the stems and their retreat into confusion is also minimal. In the layer of long-stem flax (over 110 cm) there can be two ridges at the same time; however, their location in this case is such that the comb included in the layer begins to act upon it when another comb in front of the flax stalks comes out, as a result of which there is no additional force pulling the stalks out of the clamp in the clamping conveyor 1.

The carved stems by the clamping conveyor 1 are removed from the tow chamber 2, and the tow products are moved by ridges 8 together with the blades 9 and 10 fixed on them to the heap conveyor 11, which are discharged into a container for collecting them (not shown in the diagram).

The scrubber is manufactured and tested. Since the simultaneous effect of two ridges on a layer is excluded with a three-ridged combing drum, damage to the stems and their retreat into the muddle are minimal and fit into the parameters determined by the agrotechnical requirements.
