Description

The utility model relates to agricultural machinery, in particular, to devices for inter-row cultivation of row crops.

Known section of the cultivator [Section seeder-cultivator. Patent RU No. 2268561. - Publ. January 27, 2006, Bull. No. 3.], including a suspension bracket, ridges, a copying wheel, a mechanism for adjusting the copying wheels, holders and working bodies. The copying wheel is mounted on the bed with the possibility of rearrangement along the length of the bed. The section is additionally equipped with paired support wheels with a mechanism for adjusting their position.

However, the known device has a disadvantage, which can be attributed to the unsatisfactory quality of inter-row cultivation of row crops.

The purpose of the utility model is to improve the quality of inter-row cultivation of row crops.

This goal is achieved by the fact that the working bodies are installed in the holders. The working bodies contain a rack, lancet paw, blade and bracket. The bracket is mounted on the rack, with the possibility of its vertical movement along the rack. An additional bracket with an axis is rigidly fixed with a bracket. Loosening disks and a blade are mounted on the axis with the possibility of free rotation. Riping disks perform a larger diameter than the blade, and are located between the blade and the additional bracket at an acute angle to the direction of movement of the lancet paw. The blade is flat and mounted on the inside of the lancet paw. The lower edges of the wings of the lancet paw and the lower point of the blade are in the same horizontal plane and are located at the same level.

Figure 1 shows a section of the cultivator, a side view, figure 2 is the same, a top view, figure 3 is a view A, figure 4 is a working body of the cultivator, top view, figure 5 is a section of the bracket of the worker cultivator organ along the BB line.

The cultivator section contains the suspension 1, the ridges 2, the copy wheel 3, the holders 4 and the working bodies 5. The guides 6 are mounted on the ridges 2. The guides 6 are installed at equal distances from the longitudinal axis of symmetry of the ridges 2, holders 4 are mounted with the possibility of regulating this distance. The working bodies 5 are installed in the holders 4. The required distance between the working bodies is established by moving the holders 4 along the guide brackets 6 in different directions from the longitudinal axis of symmetry of the ridge 2 and fixed in the required position with bolts 7, screwed into the threaded holes of the holders 4.

The working body of the cultivator contains a stand 8, a knife-shaped stand 9, a lancet paw 10. A bracket 11 is mounted on the stand 8 with the possibility of its vertical movement along the stand 8. The required position for the height of the bracket 11 is fixed with a bolt 12 screwed into the threaded hole of the bracket 11. With the bracket 11 an additional bracket 13 with the axis 14 is rigidly fixed. The ripping disks 15 and the blade 16 are mounted on the axis 14 with the possibility of free rotation. The blade 16 is flat and mounted on the inside of the lancet foot 10. e disks 15 are made of a larger diameter than the blade 16, and are located between the blade 16 and the additional bracket 13 at an acute angle to the direction of movement of the lancet foot 10. The lower edges of the wings of the lancet paw 10 and the lower point of the blade 16 are located on the same horizontal plane and are located on one level.

The working bodies 5 are installed in the holders 4 with the possibility of adjusting the distance between the lower edges of the wings of the lancet paws 10 and the lower point of the copying wheel 3. The necessary position of the working bodies 5 in height relative to the lower point of the copying wheel 3 is controlled by moving the rack 8 "up-down" in the holder 4 and fix in the required position by a bolt 17 screwed into the threaded hole of the holder 4.

The cultivator section operates as follows.

Pre sections are hung on the frame of the cultivator. Set the necessary distance between the working bodies 5, depending on the first or second row-spacing processing to regulate the width of the protective zone of the row of plants, for which the holders 4 are moved along the guide brackets 6 in different directions from the longitudinal axis of symmetry of the bed 2 and fixed in the required position by a bolt 7. Set the stroke depth of the lancet paws 10, for which the racks 8 are moved in the holders 4 and fixed with bolts 17, and the stroke depth of the dumps 16 in the soil, depending on the height of the plants.

When moving a cultivator with deepened working bodies, lancet paws 10 loosen the soil and cut weeds. In this case, the soil descending from the wings of the lancet paw 10 enters the working surface of the blade 16, the maximum lower point of which is in the same horizontal plane with the lower edges of the wings of the lancet paw 10 and is located at the same level, and moves towards the row of plants, filling weeds in the protective zone and hilling cultivated plants. At the same time, the ripping discs 15, installed between the blade 16 and the additional bracket 16 on the inside of the wings of the lancet paw 10, loosen the soil below the depth of the lancet paw 10, thereby preventing exposure of the bottom of the furrow. The thickness of the sprinkled soil layers depends on the height of cultivated and weed plants, and is 2 ... 4 cm in the first inter-row cultivation, in the second - 6 ... 8 cm.

The presence of the guide brackets 6 allows the holders 4 to be moved along them in different directions from the longitudinal axis of symmetry of the row 2 to control the width of the protective zone of the row of plants and, accordingly, the necessary distance between the working bodies 5, depending on the first or second row-spacing.

The implementation of the blade 16 flat and installing it from the inside of the lancet paw - allows you to shift the soil into the protective zone of the row of cultivated crops without its turnover.

The implementation of loosening disks 15 of a larger diameter than the blade 16 allows loosening the soil behind the lancet paw 10, thereby preventing exposure of the bottom of the furrow.

The installation of the bracket 11 with the ability to move it together with the additional bracket 13 and the axis 14 in height allows you to adjust not only the depth of loosening of the soil with the loosening disks 15, but also the thickness of the shifted soil layer by the blade 16 in the protective zone of the row of plants. This improves the quality of inter-row cultivation of row crops and improves the temperature, water and air conditions for the development of plants.

Sprinkling weed plants in the protective zones of crops helps to suppress their seedlings, and the hilling of cultivated plants contributes to the formation of subordinate roots in them. At the same time, a soil layer 2 ... 4 cm thick allows you to fill in seedlings of weeds, preventing their germination, without damage to cultivated plants. In the second inter-row cultivation, a soil layer of 6 ... 8 cm thickness also allows you to fill in seedlings of weeds without damage to cultivated plants, while hilling cultivated plants, and create conditions for the development of subordinate roots of cultivated plants in it.

The installation of the working bodies 5 in the holders 4 with the possibility of adjusting the distance between the lower edges of the wings of the lancet paws 10 and the lower point of the copying wheel 3, allows you to adjust the depth of loosening of the soil depending on the first or second row cultivation.

By improving the quality of inter-row cultivation of row crops, by creating favorable temperature, water and air conditions for quick and friendly germination of seeds, the yield of cultivated crops is increased.
