Description

2. The engraver according to claim 3, about the t. And that the drive for moving the cutting knives is made

in the form of a winch; the ends of the cables are connected to the ends of the brackets.

The invention relates to agriculture and can be used in machines for striking plants, preferably cotton. A chaser operating an apparatus hinged on a tractor by means of a hinged linkage with a hydraulic control cylinder is known, the hydraulic cylinder being controlled by the tractor driver from the tractor cab ij. However, due to the tractor driver's workload associated with controlling the tractor, his fatigue is rapid and he is not able to additionally monitor and control the height of the cutting unit. The closest in technical essence to the invention is a cotton chaser containing a minting machine mounted on a tractor, horizontal cutting knives of which are mounted on vertical shafts with driving pulleys, and a bushes height sensor mounted on the apparatus, made in the form of two vertically arranged photodetectors and an illuminator It is associated with the mechanism for controlling the positioning of the cutting knives, which are driven by the movement I. However, in the well-known chaser, the change in the installation height of the knives is accomplished by moving the entire cutting apparatus up to 250 kg in vertical direction, as a result of which the automatic tracking of the height of the cotton bushes being processed does not productively consume energy to change the installation height of the chaser's knives. The purpose of the invention is to increase the economy and speed of installation of horizontal chaser cutting knives to the required height. The goal is achieved by the fact that in a cotton chaser, containing a minting machine mounted on a tractor, horizontal cutting knives of which are mounted on vertical shafts with driving pulleys, and a bush height sensor installed on the machine. two vertical photo receivers and an illuminator connected to the cutting knife position control mechanism, having a displacement drive; vertical shafts of horizontal cutting knives are mounted for movement in the drive pulleys by means of a splined connection, and the cutting blade position control mechanism is connected to the upper and the lower parts of the vertical shafts are the brackets interconnected in the middle part of the thrust located in the guide. The drive for moving the cutting blades is designed as a winch, the ends of the cables of which are connected to the ends of the brackets. FIG. 1 shows the functional scheme of the cotton chaser; in fig. 2 is a view A of FIG. 1j in FIG. 3 is a section BB in FIG. one; Fig. 4 is a kinematic diagram of a knife lifting drive; in fig. 5 is a sectional view BB in FIG. 3 .. The cotton finder contains a crossbar 2, which is attached to the base tractor 1 in front, to which bracket 3 is attached, ending with cup 4 with two bearings. 5 and b, fixed by a cover 7 and bolts 8. A hollow shank of a driving pulley 11, having a keyway with an installed key 12, protected from falling out by a bar 13 and a screw 14, is fitted and secured to the inner ring of bearings 5 and b by a washer 9 and a nut 10 and secured from a strap 13 and a screw 14 through a hollow shank of the driving. also with a groove floor key. Thus, the vertical shaft 15 can only axially move relative to the drive pulley 11 through a splined connection, and the rotation transmitted by the belt 16 to the drive pulley 11 is transmitted through the vertical shaft 15 to a stamping machine having horizontal cutting knives 17. To the ends of the vertical shaft 15 the upper 18 and lower 19 brackets are hinged, attached to the opposite ends. the ends of the cable 20, the thrust of the 21 in a rigid structure in the form of a bracket that can move along a fixed guide 22. The cable 20 is wound on 6ap.ciban electric winch 23. To the brackets 18 and 19 is mounted a bushes height sensor, consisting from the upper 24 and lower 25 photodetectors, the illuminator 26 and the frame 27, functionally connected via the control knob control unit control unit 28, having a displacement drive, made in the form of an electric winch 23.

The cotton maker works as follows.

When the base tractor 1 moves, the tops of the plants will periodically overlap the photodetectors 24 and 25 of the illuminator 26. The resulting pulses are fed to the control unit 28, which produces commands (to raise the horizontal knives 17 when the pulses are received from both the photodetectors 24 and 25, to stop pulses come only from the lower photodetector 25, lowering - no pulses), which are supplied to the electric winch 23, acting through the cable 20 on the brackets 18 and 19, which leads to movement of the rod 21 along the guide her

22, while the vertical shaft 15 also moves vertically in the direction corresponding to the command. At the same time, it rotates under the action of a pulley 11, which in turn is driven into rotation by the belt 16. As a result, the horizontal knives 17 attached to the vertical shaft 15 cut off the tops of the plants at the desired height.

The ability to manipulate the level of horizontal knives with a considerably smaller mass (as determined in the proposed chaser, mainly with a relatively small mass of the vertical shaft) allows the use of low-power electric mechanisms for this purpose. The reduction of the overall dimensions of the unit due to the exclusion from the design of the ball of the low weight of the cutting unit also positively rolls on its maneuverability.

Thus, the use of the proposed cotton chaser will increase the economy and speed of installation of horizontal cutting knives of the first chaser to the required height.
