RU2369060C2 - Rotor weeding unit for row cucurbitaceous crops - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: unit comprises a frame, an automatic hitch bracket, carrier wheels. The frame is equipped by a set of rotor discs on the horizontal axis and an additional set of rotor discs with its shoulder mounted forward to the main set. The rotor discs of the main set are fitted with the blades in the form of a flat polygon with a cutting edge. The driven discs are equipped by cutting blades which are bent in the direction of movement with the cutting angle of γ = 40…60° and sharpening angle of α = 20…30°. The unit is equipped with a rod for the discs coupling, a pole, a draw bar and a pneumatic cylinder for lifting and lowering of the driven discs when they approach a plant.

EFFECT: unit allows for the improvement of tillage quality in the cucurbitaceous crops rows.

Description

The invention relates to agricultural machinery, in particular to a device for weeding gourds in a row.

A device for thinning plants is known, including section frames with rotary working bodies and support wheels with a drive mechanism mounted on a frame by means of parallelogram linkage mechanisms and their brackets, each section is made with two-sided installation of rotary working bodies relative to support-drive wheels pivotally attached using a common for them, the framework for the bracket of the linkage mechanism (RU patent No. 392896, M. CL A01b 41/04, published on 08/10/1973, Bulletin No. 33).

The disadvantages of this tool include significant damage to cultivated plants.

A rotary tillage implement for surface tillage with weedy vegetation on the surface is known comprising a frame, an automatic coupling bracket, support wheels and a disk unit with knives mounted by leashes on a horizontal axis. Knives have the shape of a flat polygon with a cutting edge around the perimeter. The gun is equipped with additional blocks. They are installed to the main unit with ledges forward and sideways (RU patent No. 2289897, M. cl. A01B 21/08, published December 27, 2006, bulletin No. 36).

The disadvantages of this tool include the sticking of moist soil to the spring harrow and the fact that the loosening working body does not completely cut the weed in the protective zone of the row. We adopted this type of tool as the closest analogue.

The essence of the claimed invention is as follows.

The problem to which the invention is directed is the destruction of weed vegetation in a row.

The technical result is the complete destruction of weeds due to processing in a row of gourds.

A rotary tillage implement containing a frame, an automatic coupling bracket, support wheels, a rotor disc unit with knives having the shape of a flat polygon with a cutting edge mounted on a horizontal axis, and an additional rotor disc unit mounted with a step forward to the main unit, characterized in that the driven discs equipped with bent toward the movement cutting blades with a cutting angle γ = 40 ... 60 ° and a sharpening angle α = 20 ... 30 °, while the gun has a bar connecting the discs, as well as a stand, rod and pneumatic cylinder lifting and lowering of the clutch disc when approaching them to the plant.

The invention is illustrated by drawings.

Figure 1 shows a top view of this gun.

Figure 2 shows a side view of the gun.

Figure 3 presents the rotary disk.

Figure 4 presents the knife of the leading rotor disk.

The cultivator for weeding gourds has a frame 1, a linkage mechanism 2, an upper adjustable link of a parallelogram suspension mechanism of the sections of the working bodies 3, a pneumatic cylinder for raising and lowering the rotor disks 4, support wheels 5, driven rotor disks, equipped with bent side cutting blades at an angle of cutting γ and sharpening angle α, the cutting edge is bent parallel to the plane of rotation of the disk 6, the joining bar of the lifting and non-lifting rotor disks 7, the lifting rack of the lifting rotor disks 8, the drive sprocket lifting th rotary disks 9, the axis of fastening elevating rotary discs 10, prohibitive rotary drive axis 11, traction hoist lifting the rotor disks 12, leading the rotor disk 13.

The gun works as follows.

When driving, the leading rotor discs 13 destroy the weed near the row, and the driven rotor discs 6 destroy the weed in the row of gourds. When the rotor disk approaches the cultivated plant, the pneumatic cylinder 4 is triggered and the driven rotor discs rise up and do not cut off the cultivated plant, then the pneumatic cylinder releases the lift traction and the driven rotor discs fall in a row and continue to destroy the weed vegetation. The drive of the leading rotor disks is carried out through interaction with the soil, and the drive of the driven rotor disks is carried out using a chain transmission. The teeth of the driven rotor disks are bent in the opposite direction relative to the leading rotor disks and due to the different number of teeth on the sprocket, the driven rotor disks rotate at a higher speed than the leading rotor disks. When the cutting angle is less than 40 ° and the grinding angle is less than 20 °, insufficient resistance arises and both pairs of rotor discs simply roll without destroying weed vegetation, and when the cutting angle is more than 60 ° and the grinding angle less than 20 °, a large resistance arises and the drive rotor disc cannot turn slave and both drives stop.

The use of this tool provides a more efficient way of processing gourds with the least damage.
