Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry and can be used in machines for feed production. The rotary mower with a tiered conditioner comprises a cutting device with rotating discs 2 and knives 3 hingedly mounted on with. On the discs 2 the drums are rigidly vertically fastened representing truncated cones 4 with beater rods 5 in their upper part. The beater rods 5 are tubes of circular section and are mounted at the upper part of the truncated cones 4 in rigidly fixed diametrically opposed sleeves 6. The outer part of the sleeve 6 is made flush with the generators of the truncated cones 4. The symmetry axis of the diametrically opposed sleeves 6 is parallel and/or perpendicular to the knives 3 of the discs 2. The beater rods 5 are attached by the split-pinned fingers 7 located in the openings made in the beater rods 5 and the part of the sleeves 6 which is located inside the truncated cones 4. To avoid entering into the truncated cones 4 of the vegetation mass they are equipped with caps 8 which are mounted at the top of the truncated cones 4.

EFFECT: rotary mower provides high quality processing of mowed plants.

Description

The invention relates to agricultural machinery and can be used in machines for feed production.

Known rotary mower [1], including a supporting beam, mounted on it chamfering rotors and the rotor drive mechanism located in it. Cutting rotors installed in at least two tiers, located one above the other, have cutting elements (knives) placed at a distance of at least 150 mm from each other vertically. The cutting elements (knives) are located in their tiers on rotors pairwise rotating towards each other, and the knives of the lower tier rotors with the knives of the upper tier are mounted in mutually perpendicular planes, symmetrically to each other relative to the axes of the rotors.

The disadvantage of this mower is the complexity of the design, as well as the fact that the rolls after processing with flat bats contain a decent amount of short segments of plant stems that are lost, especially when harvesting hay.

Known rotary mower with air conditioning [2], containing a cutting device with an even number of rotating disks with fixed knives and vertically mounted drums with bills. Concave bills are installed in the upper part of the drums by means of rectangular slots made in mutually perpendicular planes at different vertical heights, with a tent or a cup perpendicular or parallel to the lower knives, and the beats are secured from the inside of the drums with cotter pins.

The disadvantage of this mower is that in the process of processing the mowed stems of the plants, the flat beats form a decent amount of short sections that are lost, especially when hay is harvested.

The purpose of the invention is to improve the quality of processing of mowed plants and reduce losses.

This goal is achieved by the fact that the rotary mower with longline air conditioner contains a cutting apparatus with rotating disks with hinged knives and vertically mounted drums with beats in their upper part, fixed from the inside of the drums. The drums are made in the form of truncated cones rigidly attached with the lower part to the disks and equipped with caps and bushings in the upper part that are rigidly fixed diametrically opposite, the axis of symmetry of which is parallel and (or) perpendicular to the disk knives, and round bends are installed in the bushes and are fastened with splinted fingers through holes made in the bills and that part of the bushings that is inside the truncated cones, while their outer part is flush with the generatrix of the truncated cone sa

Figure 1 shows a front view of a rotary mower with a tiered conditioner, figure 2 is a sectional drum.

A rotary mower with a tiered air conditioner comprises a supporting beam 1 with rotating disks 2 with knives 3 pivotally mounted on them and vertically rigidly fixed drums on disks 2, which are truncated cones 4 with bills 5 in their upper part. Bills 5 are tubes of circular cross-section and are installed in the upper part of the truncated cones 4 in rigidly fixed diametrically opposite bushes 6, the outer part of which is flush with the generators of the truncated cones 4. The axis of symmetry of the paired bushings 6 is parallel and (or) perpendicular to the knives 3 of the disc 2 The bead 5 is fastened with cotter pins 7 through holes made in the beater 5 and that part of the bushings 6, which is inside the truncated cones 4. To prevent the truncated cones 4 from getting inside the plant They are equipped with lids 8, which are mounted on top of truncated cones 4 with self-tapping screws.

Rotary mower with tiered air conditioning operates as follows. When the tractor with the mower moves across the field, the torque from the tractor PTO is transmitted to the discs 2 located on the supporting beam 1 with knives 3 pivotally mounted on them and rigidly mounted vertically fixed drums - truncated cones 4 with bills 5 in their upper part. When the rotary mower is moved to the grass stand, the hinged knives of the 3 discs 2 cut the grass, and the round beater 5 rigidly fixed in the bushings 6 with cotter pins 7 inside the truncated cones 4 hit the stems of the plants, injured, crushed them and laid on the field in well aerated rolls, which significantly speeds up the drying of mowed grass. The outer part of the sleeves 6 is flush with the generators of the truncated cones 4 for a better descent of the treated mass. Covers 8, which are mounted on top of the truncated cones 4 with self-tapping screws, prevent the ingress of truncated cones 4 of plant matter. During operation, the beat 5 can be installed parallel or perpendicular to the knives 3 of the disks 2.

The use of easily installed round beats for mowing allows for intensive processing of plant stems and reduces losses due to the reduction of short stems in a heap.
