(54) ROTARY BATHING FOR COTTON

one

The invention relates to agricultural machinery, in particular, tools for processing row crops, such as cotton.

A rotary hoe is also known, including a frame and hinged on it by means of links and a spring-loaded rod of a section of the working members, made in the form of freely rotating finger discs mounted in series on parallel axes fixed on frames, with the axes of the thumb disks being cranked, mounted in supports and provided with detachable ones, and the spring-loaded shaft is connected by means of hinges and levers with crankshafts, of finger disks 1.

A rotary hoe is also known, which includes the frame of the gun, sections with middle and lateral finger discs mounted in series on parallel axes x 2.

However, the known hoes do not sufficiently effectively ensure the destruction of the soil crust formed after precipitation, especially in areas with uneven sowing rows.

The aim of the invention is to improve the quality of tillage in sowing rows.

The goal is achieved in that the section with the middle finger discs is located behind the section with the side finger discs and is connected with them by means of a spring-loaded bar and a spacer link.

The rotational hoe consists of the main section I. The carrier side finger disks 2, 3 and the additional section 4, which carries the middle finger disks 5. The main section 15 includes section 6, rigidly attached to the frame 7 guns, link 8, spring rod 9 and frame 10 finger discs 2 and 3. On the frame 10, axes 11 and 12 are fixed parallel to each other, carrying freely rotating side finger discs 2 and 3, designed to process the edge plots of sowing fields. The link 8 and the spring-loaded rod 9 with the frame 10 of the lateral finger disks 2, 3 and the pillar 6 are connected pivotally. The additional section 4 is installed with the possibility of oscillations relative to the main section 1 (in a vertical plane) and has an axis 13 with pairs of middle finger disks 5 mounted on it, a spring-loaded rod 14 and a spacer link 15. The spring-loaded rod 14 is connected to the pillar 16 with its other end rigidly mounted on the frame 10. The expansion link 15 is installed pivotally with the rear axle 12 of the main section 1. The hoe works as follows. When the rotational rotation of the hoeing disks 2, 3, and 5 of the main section 1 and the additional 4, destroy the soil crust near the cultivated plants in bands on both sides of the row. When the finger disks 2 and 3 meet with irregularities, under the action of the spring-loaded rod 9, it is transmitted to the frame 10, and through it to the finger disks 2 and 3, which descend to contact with the soil, buried in it. Thus, the areas located laterally from the middle of the row are first treated. With a relatively flat surface, the floor of the main section 1 and an additional 4 operate in the same horizontal plane. In this case, the side surfaces of the row are first treated with finger discs 2 and 3, and then the middle section with finger discs 5 of the additional section. If the relief of sowing rows varies within the lateral dimensions of the hoe section (in length and width), then the additional section 4 operates with a height offset relative to the main section 1 of the hoe within the stroke of the spring-loaded rod 14. The additional section 4 moves relative to the axis 12 by the spacer link 15 and the spring-loaded rod 14, which has reciprocating and oscillating movements with respect to the rack 16 rigidly mounted on the frame 10. The spring of the rod 14 is matched with such a power characteristic ticking and working to ensure this movement. Thus, the design of a rotary hoe allows for better destruction of soil crust with a copying effect on complex reliefs resulting from agricultural practices and precipitation. Claim of the invention Rotational hoe for cotton, comprising a gun frame, sections with middle and lateral finger discs sequentially installed on parallel axes, characterized in that, in order to improve the quality of tillage, the section with middle finger discs is located for sections with lateral finger discs and connected with them by means of a spring-loaded bar and spacer link.
