Description

i11

The invention relates to agricultural machinery, in particular, can be used for flax cleaning in flax harvesting machines.

A stripping machine is known for combining, including a flax clamping transporter and a stripping drum angled to it with three ridges, the planes of which, during rotation, always remain parallel to Cl.

The disadvantages of this combing device are the bending of flax stalks when batting relative to the clamping conveyor, which leads to their fracture and increased withdrawal into confusion, as well as a small stripping area, which does not allow to completely remove the seed boxes with various stubs of various lengths.

Closest to the present invention is a flaking device, comprising a clamping conveyor, two Strippers placed one above the other, the crests of one of which are offset relative to the crests of the other, the teeth of the crests in the direction of movement of the stems are increased in height, and the drive mechanism 2.

However, in this device, the upper and lower scraping devices are rigidly fixed to the frame, as a result of which the distance between the bases of the comb ridges of each pair of upper and lower devices during operation remains constant. When the flaking layer is thickened, this leads to damage to the productive part of the stems, breakage and increased their withdrawal into confusion. With a thin layer of combed flax, i.e. of low-yielding flax, part of the stems slips through the gaps between the teeth of the uncombed, which reduces the purity of the tow. The purity of the bat is also reduced due to the small area of the bat of the device when batting a multi-colored flax, i.e. while stripping at the same time, flax of various lengths with a seed box of 60-70 L: m.

The purpose of the invention is to reduce the stems waste in the confusion and increase the purity of flakes of various flax by copying combing constantly changing thickness of flax ribbon and their impact on flax throughout the whole seed pill.

This goal is achieved by the fact that in the device for flaking flax stalks, the combing device is made in the form of a belt comb conveyors, whose frames outside the stripping area are pivotally connected to each other with the possibility of rotation in the longitudinal-vertical plane and spring-loaded.

In this case, the springs have adjustment devices.

FIG. 1 shows a device for stripping flax stems, side view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2

The device for stripping flax stalks contains a clamping conveyor 1, one of the combing devices located one above the other in the form of ridges 2 offset from each other, mounted on sleeve-roller pegs 3, envelopes leading A and driven 5 asterisks fixed on leading 6 and driven 7 shafts . The top frame 8 and the frame 9 bottom scraping devices for copying the thickness of the combed flax are interconnected by means of bows 10 located in a plane passing through the axes of the driving shafts 6. The required force of the stripping ridges 2 on the flax is reached by compression springs 11, worn on The studs 12, one end of which are secured with nuts 13 to the frame 9 of the lower combing device, and the second has the ability to move in the elongated holes of the frame 8 of the upper combing tool. The amount of compression preload of the springs 11 is adjusted by nuts 14. The minimum clearance between the stripping devices is established by nuts 15.

Closed belts 16 are fastened to transport the flax heap to the exit from the stripping devices and prevent the stems from winding on the leading 4 and driven 7 shafts between the chains 3.

The device for stripping flax stems is driven by a sprocket 17 mounted on the drive shaft 6 of the upper combing device. The drive shafts 6 of the upper and lower combing devices are interconnected by chain gear 18 with sprocket spacing 19. The device for stripping flax stalks works as follows. The clamping conveyor 1 moves the stems in the direction shown in FIG. 2 by an arrow. Due to the increasing length of the teeth, the stems freely enter the gap between the upper and lower combing devices and due to the movement of the combing ridges 2 in the direction from the clamping conveyor 1, the seed bursts from the stalks that fall into the gaps between the teeth of the flesh, due to the frame connection “ the upper frame and the lower stripping frame 9 by the hinges 10, when the thickness of the flax layer is increased, the stripping devices, overcoming the resistance of the springs 11, are removed from each other, and when reduced, they are returned to running position. At the same time, the amount of removal of the crests of one device from the crests of the other increases as the hinges 10 move away from the axis. Since the flax ribbon is facing apical part towards the hinges 10 and its thickness increases as the hinges of the hinges of the hinges are removed, automatic copying is permanently provided the thickness of the layer of combed, flax 2 combing, depending on the yield of flax and the translational speed of the aggregate. This eliminates the breakage of the stems by the bases of the combing ridges, and therefore, significantly It lowers the waste them putaninu and generally in the presence of putaniny heap. In addition, the automatic copying of combing ridges 2 of the thickness of the flax layer makes it possible to increase the purity of the low-yield flake by combing the stems in the protuberances between the teeth of the ridges as the combing devices approach each other. The sufficient length of the stripping devices, which ensures that the entire area of the bolls is located, also makes it possible to increase the purity of the multi-colored comb.
