Abstract

FIELD: agriculture.

SUBSTANCE: mower with flail conditioner comprises a cutting device with rotating discs 2 with hinged blades 3 and vertically mounted drums 4 with beaters-flails fixed in the upper part. The drums 4 are made in the form of removable cylindrical tubes or truncated cones. The drums 4 are rigidly attached to the discs 2 by flanges located in the upper part. The hinged beaters-flails are made of steel of round, hexagonal, square section or from the strip. The beaters-flail links are mounted on the outer surface of the drums 4 with U-shaped brackets 7 located diametrically opposed in parallel or perpendicular to the blades 3 of the discs 2. The length of beaters-flails does not exceed the distance between the U-shaped brackets 7 and the blades 3 of the discs 2.

EFFECT: use of the rotary mower enables to carry out qualitatively processing of grass during mowing and ensures their rapid wilting.

Description

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

Known rotary mower for accelerated drying of herbs [1], including a supporting beam, mounted rotors and the rotor drive mechanism located therein. The rotors are located one above the other, installed in three tiers and are equipped with cutting and beating working elements, the lower and upper rotors are equipped with knives, and the middle rotor is equipped with beams located at a distance of 80 mm from each other vertically. Knives and beats are located in their tiers on rotors in pairs rotating towards each other. The knives and beaters of the rotors of the lower, middle and upper tiers are installed at an angle of 60 ° relative to each other.

The disadvantage of this mower is the design complexity.

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. The concave-shaped beater is installed in the upper part of the drums by means of rectangular cuts made in mutually perpendicular planes at different vertical heights, with a tent or a cup perpendicular or parallel to the lower knives, and the beater is secured from the inside of the drums with cotter-pin fingers.

The disadvantage of this mower is that during the processing of mowed plants, rigidly fixed bats can be damaged when they meet obstacles, such as stones, etc. during mowing.

The purpose of the invention is to simplify the design and increase reliability during operation.

This goal is achieved by the fact that the mower with a chain air conditioner contains a cutting apparatus with rotating disks with hinged knives and vertically mounted drums with saws fixed in their upper part. Drums made in the form of removable cylindrical pipes or truncated cones, rigidly attached by flanges located in their lower part to the disks, in the upper part are equipped with hinged beats - chains made of steel of round, hexagonal, square section or from a strip, the chain links of which are fixed on the outer surface of the drums with U-shaped brackets diametrically opposed parallel to or perpendicular to the blade knives, and the length of the flails does not exceed the distance between the U-shaped brackets ynami knives and discs.

Figure 1 shows a diagram of a rotary mower with a chain air conditioner: figure 2 is a side view in section on a drum of a rotary mower; figure 3 - U-shaped bracket.

A rotary mower with a chain air conditioner contains a supporting beam 1 with rotating disks 2 with knives 3 pivotally mounted on them and vertically mounted drums 4 rigidly mounted on disks 2, which are cylindrical pipes or truncated cones (not shown conditionally) with chains - articulated bills 5 in the upper their parts. Beat 5 flails are made of steel of round, hexagonal, square cross-section or from strip and chains 6. The first link of each chain 6 is welded to the beat 5, and the last is attached externally to the surface of the upper part of the drums 4 by U-shaped brackets 7 through holes 8. Brackets 7 located diametrically opposite in parallel or perpendicular to the knives of the 3 disks 2. For stable operation of the mower, the length of the flails (beat 5 and chains 6) should not exceed the distance between the U-shaped brackets 7 and the knives 3 of the disks 2.

To prevent ingress of drums 4 (cylindrical pipes or truncated cones) of plant mass, in the upper part they are equipped with covers 9, which are attached to the fixing rings 10 with self-tapping screws 11.

In the lower part of the drums 4, flanges 12 are rigidly fixed, by means of which the drums 4 are mounted to the rotating disks 2 of the bearing beam 1.

During operation, due to centrifugal forces, the flails (beat 5 and chain 6) are straightened. When encountering an obstacle while mowing grass, they easily deviate from their working position. Deviation of flails can occur up - down, forward - backward. After contact with an obstacle, they are straightened again due to centrifugal forces.

For ease of operation, the drums 4 are removable.

A mower with a chain air conditioner operates as follows. The field includes the tractor's PTO. Disks 2 with drums 4, located on the bearing beam 1, begin to rotate. Knives 3 disks 2 and flails, consisting of beat 5, made of steel of round, hexagonal, square cross-section or of a strip and chains 6, mounted in the upper part of the drums 4, made in the form of removable cylindrical pipes or truncated cones, are straightened by centrifugal forces and occupy a working position.

The chains consist of beaters 5 and chains 6, the first links of which are welded to the beats 5, and the last through holes 8 are attached to the outer upper part of the reels 4 with U-shaped brackets 7. The brackets 7 are diametrically opposed parallel or perpendicular to the knives 3 of the disks 2.

When a tractor with a mower moves across the field, the hinge knives of 3 disks 2 cut grass, and the hinged beats of 5 flails hit the stems of the plants, injure, bend, partially tear them and lay them on the field in well-aerated rolls, which greatly speeds up the drying of the cut grass.

For stable operation of the mower, the length of the flails (beat 5 and chains 6) should not exceed the distance between the U-shaped brackets 7 and the knives 3 of the disks 2.

Chains when encountering an obstacle while mowing grass easily deviate from their working position. Deviation of flails can occur up and down, back and forth. After overcoming the obstacles, they again straighten due to centrifugal forces. To prevent ingress of cylindrical pipes or truncated cones of drums 4 of plant mass, in the upper part they are equipped with caps 9, which are attached to the rings 10 with self-tapping screws 11. The drums 4 are removable for ease of operation. They are installed on the discs 2 of the mower through the flanges 12.

The use of this technical solution with a simplified design will provide increased reliability during operation, which will result in a high-quality process of processing herbs during mowing and to accelerate their wilting in the field.
