Abstract

The invention relates to agricultural machinery and can be used for mechanization of work in horticulture, in particular for mowing grass between rows with simultaneous mulching of the soil in rows. The mower contains a frame with an attachment that rolls on self-aligning wheels, and two sections of rotors with knives and drives symmetrically mounted at an angle to the direction of movement. The knives are equipped with blades, and the rotors of each section have proportionally decreasing diameters and are mounted with the possibility of one-way rotation by means of a drive, and the direction of rotation of the rotors of these sections is opposite. The invention allows to mow grass in the aisles of the garden in one pass with the simultaneous mulching of the soil in rows. In this case, the sequential movement of the unit along the aisles, regardless of the direction of movement, provides the same mulching of adjacent rows of the garden.

Description

The invention relates to agricultural machinery and can be used for mechanization of work in horticulture, in particular for mowing grass between rows with simultaneous mulching of the soil in rows.

Known mower KIU-2A, designed for mowing and chopping grass and green manure between rows of orchards, vineyards and berry stands for green fertilizer containing a frame with a hitch and a support roller, two rotors with knives and a drive [1]. In operation, the knives cut and chop the grass. The cutting height is regulated by rearranging the track roller, and the grinding quality is controlled by the translational speed of the unit. The beveled and crushed mass remains in place in the aisles, forms a mulching layer, which subsequently turns into a green fertilizer.

The disadvantage of this device is that it leaves the mulching material in the aisles, that is, where there are no roots of fruit trees that need fertilizer.

Known garden mower KRS-2.5A [1], containing a frame with a hitch and a road roller, rotors with knives, a drive and an additional remote rotor for mowing and chopping grass in a row of fruit trees.

The disadvantage of such a mower is that it leaves mowed and shredded grass in the swath and is not able to throw the mulch material in a row and a ramp zone when it is kept under black steam and there is no vegetation there.

The prototype is a garden mower [2], which contains a frame attached to the attachment with the possibility of lateral displacement relative to the longitudinal axis of the tractor and rolling on self-aligning wheels, rotors with knives and rotor drive, in which the line of rotor centers is located at an angle to the direction of movement, rotors

have proportionally decreasing diameters, and the knives are equipped with blades and are mounted with the possibility of one-way rotation by means of a drive.

When the mower moves along the aisle of the garden, the green mass is mowed with rotor knives. Part of the mown mass in the direction of rotation is thrown into a row of trees from blows by the blades of knives. Another part of the cut grass falls into the area of action of the knives of the next rotor and the process repeats. The location of the line of centers of the rotors at an angle to the direction of movement allows you to get the necessary sector of the ejection of the beveled mass. The proportionally decreasing rotor diameters provide a different range of grass casting and the formation of a uniform mulching layer in a row of trees.

The disadvantage of this design is that in narrow aisles of intensive gardens, grass mowing is carried out in one pass by increasing the working width and the asymmetric arrangement of the mower in the unit complicates the pattern of movement between rows. There is a need to break the garden into corners, and inevitably there will be rows with a double dose of mulch material and rows in which the mowed mass is not thrown at all. In addition, with an increase in the width of the mower, the quality indicators of its operation are reduced, namely: there is an increased dispersion of grass in the swath; the uniformity of the distribution of the mulching layer along the width of the near-trunk strip decreases.

A garden mower is proposed, containing a frame with a hitch and support wheels, a section of rotors with knives and a drive, in which the line of centers of the rotors is located at an angle to the direction of movement, the rotors have proportionally decreasing diameters, and the knives are equipped with blades and are installed with the possibility of one-way rotation by means of a drive. The mower is equipped with an additional section of rotors with an independent drive, located symmetrically and mirror

the said section, and the direction of rotation of the rotors with knives of these sections is opposite.

The presence of an additional section of rotors with knives allows you to double the width of the mower's grip without reducing the quality of work and ensure mowing of row-spacings in intensive gardens in one pass of the unit. The symmetrical arrangement of the two sections of the rotating rotors allows you to evenly cast the beveled mass on both sides, both in the right row and in the left row. In this case, the sequential movement of the unit along adjacent row spacings, regardless of the direction of movement, provides the same mulching of all rows of the garden.

Figure 1 shows the device, a top view; figure 2 is a side view of the device, on the right; figure 3 and figure 4 depict the knives of the sections of the rotors in sections aa and bb in figure 1.

The garden mower contains a frame 7 with an attachment 2 and rotor sections 3 and 4 with knives 5, 6 and drives 7, 8, providing one-sided rotation of the rotors in each section. The knives are equipped with blades 9, 10. The sections of the rotors 3 and 4 are mounted in the frame 7 with the possibility of rotation in a horizontal plane relative to the axes of the first rotors 77 and 12 by means of screw mechanisms 13 and 14, and the back part is supported by self-aligning wheels 75 and 16.

Before starting work, the mower is hung on the tractor, the rotor drives are connected, the cutting height is set using the support wheels 75, 16, and the angle of attack of the rotors is set using screw mechanisms 75, 14 in accordance with the width of the tinned part of the garden aisle. Then turn on the rotor drive and begin to move. When the unit moves along the aisle of the garden, the green mass is mowed by the rotating knives of the rotors and thrown into a row of trees. Moreover, the rotors of section 3 discard the mowed grass in the right row, and the rotors of section 4 - in the left row in the direction of movement of the unit.

The effectiveness of the proposed device is achieved by increasing the width of the mower and ensuring grass mowing in the rows of the intensive garden in one pass, as well as by uniformly ejecting the mulch material on both sides of the unit and ensuring the same mulching of all rows of the garden.
