Description

Groove digging machines for trapping field pests, using rotating knives and plow blades located in several plots and plow dumps, are generally known. In the proposed machine, the arrangement of knives and plows and of the rear inclined circular knife, which is also available, is combined in such a way that the rotating knives running ahead form a ditch, the bottom of which receives in cross section a slope to one side wall (board) of the ditch, but this slope immediately it is leveled with earth, obliquely trimmed from the lower part of the other side wall with a rear inclined disk knife, and then the bottom is smoothed by the next plow behind it.

In FIG. 1 depicts a view of the proposed machine from the side; FIG. 2 shows it from above and FIG. 3 is a cross-section of the machine groove.

The machine, when operated, is driven by a tractor, from which shaft 7 (fig. 2) is moving the whole mechanism. tires located on the frame 2 supported by two wheels 5. The main part of the machine is the drum #, which sits on the movable axle 5 and receives rotation from the shaft / through gear 9-W and

the hinge chain 77, the drum axis 5 is fixed on two, sector-shaped frames 72, 72 integral with the shaft 73, which lies on bearings 14-14 and also serves as an axis for bevel gear W and for one wheel of chain transmission 77. One of the frames 72 is provided with an arc rack 75, with which the gear 16 engages, driven by a worm gear from a shaft 77, rotated by a wheel 75 by a machine driver; Thus, the latter can set the drum 4 to the desired height position.

On the drum 4, the main 7P knives that cut through the soil are fixed, 19 of unequal length, located in different planes (four pieces in four places — sixteen in total) along the length of the drum, i.e. across the width of the ditch, and, moreover, in such a way that their pointed ends (blades) are at different distances from the axis of the drum, on one straight line inclined relative to the side surface or axis of the drum. With this arrangement, the knives 19, digging out the ditch when they rotate, process its bottom with an inclination in the transverse section of the pit towards one wall, as shown by the dotted line in FIG. 3. At the front of the drum 4 with nokhchi there are two guides parallel to the disk 2 (20 with an interval between them equal to the width of the ditch.

To remove the ground dug by the blades 19 behind the drum 4, an inclined auger 2 / is mounted in the box 22, which is pivotally suspended on the axis 23 and can be raised and lowered simultaneously with the drum 4 due to its connection 2 / / with sector-like frames / 2 supporting axis 5 of the drum. In this case, the movement of the box 22 with the auger in a strictly vertical plane is guided by two steep runners 25, between which this box slides. The auger shaft 2 / is reinforced with a small part in the plowshare 26, which is integral with the chuck 22 and placed directly behind the drum 4, and its upper part at the rear upper wall of the chink 22, the auger receives rotation from the tubular shaft 27 worn on the shaft / 3, through two chaining gears 28 and 29 and bevel gears 30 and 37. As the screw rotates, the auger pulls the ground upward with the blades 79, where it rolls down on two sides of the dug ditch along two inclined platforms 32, 32.

As already mentioned, the knives 79 produce a ditch with a sloping bottom (Fig. 3); in order to bring the bottom into a horizontal view, an inclined disk knife 34 and a plow 315 placed in the rear part of the rack 33 are applied to it and a plow 315 placed behind it. When the machine is running, this knife makes an oblique notch at the bottom of the wall opposite to the bottom recess the land is rolled in the direction of the recess and with the plow 35 the bottom of the ditch is finally flattened.

The subject matter of the invention.

Claims (2)

1. A machine for digging grooves for trapping field pests using rotary shears and plow dumps, characterized in that the blades of a number of rotating knives 79 are installed at different distances from their axis of rotation jp, nz to obtain a groove with a sloped sideway the bottom, located at the highest point of the latter, with its bottom edge, the plow 35 with the blade serves for oblique cutting the bottom of the other side of the groove and filling it with the cut soil of the bottom of the groove in order to align it with the horizontal plane STI. 2. In the machine of claim 1, application for facilitating the operation of the plow 35 mounted obliquely before the last of the disk knife 34. FIG. 2
