Abstract

FIELD OF THE INVENTION The invention relates to agriculture, in particular to implements for the care of sowing of melons and gourds. The purpose of the invention is to improve the quality of embossing lashes. The engraver of whips of melons and gourds contains a cutting knife 2. The working section of the knife 2 is located in the zone of the central angle of circumference of the support-pressure wheel 3. The central angle is 30-40 °, its bisector is located vertically, and the top is directed upwards. Moreover, the knife 2 with horizontal and longitudinally vertical planes passing through the upper point of the blade of the knife 2 forms acute angles, the tops of which are directed in the direction of movement of the unit. During the movement of the chaser, the retention of the scourge is carried out by the support-pressure wheel 3, which presses the scourge to the soil before interacting with the cutting knife 2, which allows the cutting process to be performed without pressing and moving the scourge. 2 Il.

FIELD OF THE INVENTION The invention relates to agriculture, in particular to implements for the care of sowing of melons and gourds.

The purpose of the invention is to improve the quality of embossing lashes.

On / Fig. 1 shows a chaser of lash of melons, side view; in fig. 2 - the same, top view.

The engraver of whips of melon crops contains frame 1 with a cutting knife 2 installed on it and a support-pressure wheel 3. The cutting knife 2 is installed so that its working section (section AB, located in the soil) is located in the zone of the central angle of the support wheel ... 40 °, the bisector of which is located vertically, and the top is directed upwards. In addition, the cutting knife 2 with horizontal and longitudinal-vertical planes passing through the upper point of the knife blade (point C) forms acute angles, respectively, f3 and a, whose vertices are directed in the direction of movement of the unit.

By installing the knife 2 at an acute angle from. to the longitudinal-vertical plane, the gap between the end of the rim of the support-pressure wheel 3 and the knife 2 in the front part is smaller than in the rear. The gap in the front of the selected minimum allowable, so that when moving the unit the knife does not touch the wheel. Cutting knife 2 on the frame I is hinged around each wheel.

The chaser works as follows.

The support-presser wheel 3, moving over the support surface (soil), presses the floss crops, which are in the pressed state within the central angle of 30 ... 40 °, to it.

Due to the mutual positioning of the cutting knife 2 and the support-pressure wheel 3, the cutting part of the knife (section AB) located in the soil begins to interact with the whip only after pressing its support-pressure wheel 3 to the soil.

It is known that the best quality of cutting various materials is achieved

when sliding cutting them. The effect of sliding cutting is most characteristic of cutting knives. Moreover, the smaller the angle p between the horizontal plane passing through the upper point of the knife blade (point C) and the blade itself, the longer the knife slides along the material being cut, as a result, the completeness of the cutting of the lashes increases.

The force P of the cutting knife 2 on the whip is laid out on the horizontal P and vertical P components.

The horizontal component tends to drag the whip along with the knife 2, and vertical to press it into the soil. Both are undesirable, as this leads to tension on the lashes, which leads to their injury. It is desirable that the section of the lash between the knife 2 and the root collar does not move during cutting. The lash is held by the support-pressure wheel 3, which presses the lash to the soil before interacting with the cutting knife 2, which allows the cutting process to be performed without pressing and moving the lash, and therefore guarantees cutting of the melons and gourds without injury to the lash.
