Abstract

The device relates to agricultural machinery, namely to machines for harvesting feed crops. The mower conditioner is designed for harvesting strong legumes and legume-cereal grass mixtures in order to accelerate the drying process by increasing the degree of conditioning, swelling of the roll and creating a ventilation duct in it. The machine contains a frame on which are installed: a breaking beam, a rotary cutting apparatus, guiding shields, flattening rollers, a beater-activator, swath-forming shields. The beater - activator with a urethane coating is made conical - cylindrical in shape, while the cone is located in the central part; the diameter of the conical part is 1.5 times larger than the cylindrical. The beater is driven from the lower conditioning roller and its rotational speed is 20% higher than the rotational speed of the rollers. Beater-activator increases the degree of conditioning, contributes to the creation of a fluffy roll with a longitudinal lower ventilation duct. The implementation of the claimed model will reduce the drying time of the roll, which will ensure the safety of nutrients in the harvested mass.

Description

The utility model relates to agricultural machinery, namely to machines for harvesting feed crops.

A flaking device [1] is known for the formation of a friable roller by actively influencing the mass of oscillating fingers mounted on an axis located behind the lower roller and provided with brackets with rollers at their ends for interaction with the longitudinal ribs of the lower roller.

The disadvantage of this device is the design complexity. The vibrating type device and its action can lead to the separation of the buds of legumes and their loss. Currently, mainly for flattening legumes and legume-cereal mixtures, flattening rollers with a urethane or rubberized surface are used to reduce damage and loss of inflorescences and leaves. The device in question operates from the interaction of the rollers with the longitudinal steel ribs of the lower roller. This device with steel edges of the rollers and with an additional vibrating device will reduce the quality of flattening and the formation of the roll, which will lead to loss of mowed grass.

A device for a mower - conditioner to reduce the density of the roll [2]. The disadvantage of this device is

increased design complexity. To implement this device, it is necessary to mount an additional frame, a longitudinal conveyor, auger and drive of these working bodies under the mower conditioner. All this leads to an increase in the metal consumption of the machine and the loss of its versatility. The quality of flattening will not improve and the loss of inflorescences and grass leaves will increase due to the active interaction on the mass of the conveyor and the spreading screw.

The aim of the invention is to improve the quality of feed by accelerating the drying process.

This goal is achieved by the fact that the mower - conditioner contains a frame on which are installed (Fig. 1): wringing beam - 1; rotary cutting apparatus - 2; guiding shields - 8; flattening rollers with urethane coating - 3; swath-forming panels - upper spring-loaded - 4 and rear - regulating the width of the roll - 6; it is equipped with a beater - activator 5 with a urethane surface having the same diameter with flattening rollers and with a cone in the central part whose diameter is 1.5 times the diameter of the cylindrical part, i.e. the center of mass flow coming out of the working gap of flatting rollers falls on the upper part of the cone, is divided and accelerated in its movement; the beater activator has a rotational speed of 18 ... 20% higher than the rotational speed of the rollers and is driven into rotation from the pin of the lower roller through a chain gear 9 (for example, with a gear ratio i = 1.18 of the drive sprocket Z ₁ = 26 and the frequency the rotation of the rollers 800 min ^{-1 the} driven sprocket will be Z ₂ = 22 and the rotation speed of the beater will be 946 min ^-1 (figure 3).

The conical part 7 (figure 3) contributes to the tossing and acceleration of the flattened mass, which leads to the discharge structure of the roll - increase its duty cycle and the formation of a longitudinal air channel ded ¹

(figure 2) for venting the lower part of the roll. Roll-forming shields, having rounded lower surfaces 6 (Fig. 3), twist and bend the roll somewhat. In this case, the roll rests as if on two "supports" d and d ¹ (figure 2) and is not subjected to severe wetting in rainy weather.

Beater - activator due to the capture and engagement of the stream of flattened mass produces a soft additional conditioning of bean herbs. There are smooth deformations of stretching, crushing and bending of the stems, leading to an increase in the dried surface of legumes. A beater activator picks up a stream of flattened mass and throws it up, forming a fluffy, easily ventilated roll, which is well blown from the side surfaces of the AV; Sun cd and av ¹ ; in ¹ c ¹ ; c ¹ d ¹ : (figure 2)

Mower - conditioner works as follows (figure 1). The laminating beam 1 tilts the grass with the tops forward, forms bunches of grass for a good cut with a rotary disk apparatus. 2. The cutting apparatus cuts the stems of the grass and feeds them (mainly the butt part) to the flatting rollers.

3. Two guide shields are used to feed the sheared mass from the extreme disks of the cutting apparatus 8. The rollers 3 capture the fed mass, flatten it and feed it to the activator beater 5. On the urethane friction surface of the beater, the mass of the flattened grass is well caught and subjected to additional deformation (stretching, crushing, bending), i.e. the degree of flattening of the grass increases (for example, from 90 to 95 ... 97%). The beater activator also helps toss and stretch the flattened mass and, together with the upper spring-loaded shield 4 and two rear roll forming adjustable shields 6, forms a roll with a easily ventilated structure (Fig. 2).

The claimed mower - conditioner differs from the prototypes in the simplicity and compactness of the design, has a lower metal consumption, provides an increase in the degree of conditioning of the mass and the creation of a fluffy, easily ventilated roll.

As a result of the operation of the claimed machine, the degree of flattening of the herbs increases and a stretched, fluffy aerated, rapidly drying roller is created. The drying time for the roll of strong legumes (yield more than 10 ... 12 t / ha) is reduced, which will ensure the preservation of nutrients in the harvested mass and accelerate all subsequent technological operations.
