Description

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

Known rotary mower design L.N. Burkova [1], consisting of a beam with rotating rotors and cutting elements pivotally attached to the rotors, and a by-pass board. The rotors of the mower are equipped with one cutting element made in the form of a steel string, at one end of which a metal load of elliptical shape is rigidly attached in two mutually perpendicular sections, and at the other end, the string is pivotally attached to a spiral coil spring, which is rigidly attached to its round end a box-shaped body rigidly connected to the rotor shaft for rotation, while in the idle state, the coil spring sets the load in the tensioned position, being inside round o box-shaped case, and the width of the cargo is larger than the hole for the string in a round box-shaped case and is located outside the specified case, while the loads of all odd rotors rotate in one plane, and the loads of all even rotors - in the other, shifted downward relative to the first one by the thickness of the load plus a tolerance of one tenth of the thickness of the load, while the loads are placed on the rotors with a shift of 90 ° around the circumference of rotation relative to each other, starting from the first, and the end face of the spiral coil spring to which the string is attached and with a load, it is made larger than the hole for the string in a round box-shaped case, and the transmission mechanism is made of a chain.

The disadvantage of this mower is the inability to provide damage to the stems of mowing plants to accelerate their drying.

Known rotary mower with tiered air conditioning [2], containing a cutting apparatus with rotating disks with hinged knives and vertically mounted drums with bills in their upper part, fixed from the inside of the drums. Drums made in the form of truncated cones are rigidly attached to the disks by the lower part and provided 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 circular bends are installed in the bushings, and fastened with forelock 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 generators of the truncated cones mustache drums.

The disadvantage of this mower is that the drums damaged during mowing and the bottom part is rigidly attached to the disks must be replaced with the disks. In addition, the round beater does not damage all the stalks of mowed herbs, and their hard fastening in contact with, for example, stones can lead to their breakage.

The purpose of the invention is to increase the intensity of processing mowed herbs, ease of use.

This goal is achieved by the fact that the rotary mower with spring air conditioning contains a cutting apparatus with rotating disks with hinged knives and vertically mounted drums with bills in their upper part. The hollow cylindrical drums are removable and fastened to the disks by means of flanges located in their lower part, and in the upper there are slots arranged diametrically opposite to the disk knives vertically, as well as horizontally along and against the rotation of the drums, in which two spring fingers are installed beaters placed outside the drums, and their coil springs with eyes are fixed inside the drums by fixing tubes installed on bushings of a smaller diameter, rigidly closed insulated on the flanges of the drums with an offset of 45 ° relative to the mounting holes of the flanges, and plugs are welded to removable covers into the upper one and holders made of strip steel with holders that curvilinearly cover coil springs with fixing tubes inside, and the straight ones are installed without horizontal displacements in the vertical slots of the drums and are bolted to their lateral surface.

In FIG. 1 is a front view of a spring-mounted mower; in FIG. 2 - the same, top view; in FIG. 3 is a side view of the drum spring air conditioner assembly; in FIG. 4 - the same, a top view without a cover; in FIG. 5 is a side view of a spring air conditioning drum; in FIG. 6 is a front view of the beater with two spring fingers; in FIG. 7 is the same side view.

A rotary mower with spring air conditioning contains a supporting beam 1 with rotating disks 2 with hinged knives 3 and vertically hollow drums 4 of a cylindrical shape rigidly fixed on disks 2 with bills with two spring fingers 5 in their upper part located diametrically opposite to the knives 3 of the 2 disks 2 vertical slots 6 with the possibility of deviation in the horizontal slots 7. The drums 4 are removable and are attached to the rotating disks 2 of the supporting beam 1 by means of flanges 8 located in the lower th parts of them. Cylindrical springs 9 beat with eyes 10 and mounting tubes 11 are located inside the drums 4, and their spring fingers 5 are outside. The fixing of coil springs 9 beat with eyes 10 inside the drums 4 is carried out by installing two tubes 11 inside the coil springs 9 on bushings 12 of smaller diameter, rigidly fixed to the flanges 8 located in the lower part of the drums 4. On top of the tube 11 are fixed by bushings 13 welded to removable covers 14 on the inside. Rigid fastening of beats is carried out by holders 15 made of strip steel, which, in one part, curvilinear, cover coil springs 9 with eyes 10, and the second, straight, are installed without horizontal displacement in the vertical slots 6 of the drums 4 between the spring fingers 5, which can be deflected in the horizontal slots 7. The beater is fixed with bolts 16 through the eyes 10 of the springs 9 and holes 17, 18, 19, made in the side surfaces of the drums 4, mounting tubes 11 and holders 15.

Removable covers 14, which prevent ingress of cylindrical hollow drums 4 of plant mass, are fixed with self-tapping screws 20 to four flat brackets 21 located inside the drums 4. For the convenience of attaching the drums 4 to the disks 2 of the load-bearing beam 1 of the sleeve 12 of the flanges 8 are offset relative to the mounting holes 22 45 °.

Rotary mower with spring 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 rotating disks 2 located on the supporting beam 1, with knives 3 pivotally mounted on them and hollow cylindrical drums 4 with cylinders in their upper part vertically fixed vertically by means of flanges 8. Each beat consists of two spring fingers 5 and coil springs 9 with eyes 10. For ease of operation, the hollow drums 4 are removable. When the rotary mower is moved to the grass stand, the hinged knives of the 3 discs 2 cut the grass, and the spring fingers 5 fixed in the upper part of the drums 4 hit the stems of the plants, injure them, crush them and put them on the field in well-aerated rolls, which greatly speeds up the drying of mowed plants. During operation and when encountering obstacles, such as stones, the fingers 5 of the spring beats are able to deflect in the opposite direction of rotation of the drums 4 in the horizontal slots 7 made in their upper part.

To prevent ingress of cylindrical hollow drums 4 of plant mass into the upper part, they are equipped with removable covers 14, which are fastened with self-tapping screws 20 to four flat brackets 21 located inside the drums 4.

In the event of a breakdown, the replacement of damaged spring drills is carried out as follows. First, the covers 14 are removed by first turning the self-tapping screws 20 out of four flat brackets 21. Then, the damaged ones are dismantled and new beats with spring fingers 5 are installed, by means of vertical slots 6 made in the upper part of the drums 4. Slots 6 and 7 are located diametrically opposite to the hinge knives 3 disks 2, as well as along and against the rotation of the drums 4. Thus, the spring fingers 5 are located outside the drums 4, and the coil springs 9 beat with eyes 10 inside the hollow drums 4. Inside the bar bans 4, coil springs 9 are fixed by two tubes 11, mounted on bushings 12 of smaller diameter, rigidly mounted on the flanges 8. Rigid fastening of the springs 9 is carried out by holders 15 made of strip steel, which in one part cover coil springs 9 with eyes 10, and the second are installed without horizontal displacement in the vertical slots 6 of the drums 4. The beater is fixed with bolts 16 through the eyes 10 of the springs 9 and holes 17, 18, 19, made in the side surfaces of the drums 4, fixing pipes sides 11 and holders 15.

For convenience of fastening the drums 4 to the disks 2 of the load-bearing beam 1 of the sleeve 12 are offset relative to the holes 22 of the flanges 8 by an angle of 45 °.

The developed rotary mower with air conditioning, which is a removable hollow drum with spring working elements, is convenient to operate and allows you to actively process plant stems and thereby intensify the process of drying them.
