Description

The invention relates to agricultural machinery.

Known agromost with snap-in for snow retention according to the patent of the Russian Federation 2099912, A 01 B, 49/00, containing a drag for the formation of snow shafts, which stretches a rope along a multi-span farm agromost working in start-stop mode. The disadvantages of this agromost are low productivity and small functionality that limit its use for other agricultural work.

The agromost also has the same drawbacks according to the patent of the Russian Federation No. 2055458, A 01 B 49/00 - for adjusting the surface of the farmland with the help of mounted implements moving along the farm of the agromost operating in stop-start mode.

The agromost is known according to the patent of the Russian Federation No. 2175175, A 01 B 49/00, on the side walls of the movable platforms of which systems are mounted for hitching removable agricultural units. The agromost also has jacks for lifting self-propelled carts and a control system for turntables, on which caterpillar movers are fixed.

The disadvantage of this agromost is that its self-propelled carts are very long, because beneath them, in addition to jacks and caterpillar movers, it is necessary to have a place to place agricultural units with their mounted systems. The large length of self-propelled carts leads to an increase in metal consumption, cost and bulkiness of the agromost.

The closest in design and capabilities aggro-bridge adopted by the author for the prototype is agro-bridge according to the patent of the Russian Federation 2163428, А 01 В 49/00, each platform of which is suspended on pull-out pins, with pull-out pins installed with the possibility of vertical movement by one gearmotor through the chain. The disadvantage of this device is that it is impossible to hang two agricultural equipment on its platform at once, for example, one agricultural equipment for preparing the soil before sowing, and the second is a planting machine or seeder. The device is not very suitable for forming a soil surface with high productivity, the same applies to the formation of snow rolls. The disadvantage is that the tangential loads that occur during agricultural work are more perceived by the retractable pins, which can damage them.

The goal is to increase productivity and expand the functionality of the agromost.

The goal can be realized because hanging boards are pivotally mounted on the lower surface of the frames with the possibility of their deviations up to 90 ° in both directions, and on the lower sides of the boards there are double-sided linings with holes for attaching removable agricultural equipment, while the frames have reversible gear motors fixed to them which, through a gear-chain transmission, deflect pendant shields with agricultural equipment attached to them or fasten the shields in an upright position, while the interchangeable agricultural equipment is fixed and the plates, the thickness of which is equal to the gap between the double-sided plates of the hanging boards, and they have holes for mounting bolts, and the location of the holes in the plates corresponds to the location of the holes in the double-sided plates, while the farm of the agromost has fixed power pins on it, which enter the corresponding holes in each frame.

Agromost has a farm 1, moving on self-propelled carts 2 with tracks 3, mounted on turntables 4, retractable pins 5 for gripping and moving frames 6 vertically, jacks 7, control cabs 8, auxiliary power and technological equipment (not indicated). On the lower side of the frames 6, hanging boards 9 are pivotally fixed with the possibility of their deflection up to 90 ° in both directions, and on the lower edges of the boards 9 there are fixed double-sided plates 10, 11 with holes for attaching removable agricultural equipment, while reversible gear motors 12 are fixed on the frames 6, which, through cardans 13, chains 14 and support rollers 15, deflect the suspension boards 9 with the agricultural equipment 16 fixed to them or fasten the boards in an upright position, while the interchangeable agricultural equipment is fixed to the plates 17, the thickness of which is equal to the gap between in bilateral plates 10 suspended panels, the plates are provided with holes 18 for fixing bolts, corresponding bilateral location holes in cover plates 10, 11, the farm has agromosta power pins fixedly mounted thereon 19 entering into corresponding openings 20 in each frame 6.

The hinged shields are mounted on hinges 21, the chains 14 have turnbuckles 22. The horizontal segments of the chains are supported by supporting rollers 23.

Retractable pins 5 are located in the tubular casing 24 and are moved vertically by means of a thread located on the body of the pins and in the sprockets 25. reversible gear motors 26 through the chain 27 move four retractable pins at once, the lower ends of which enter the holes 28 on the frames 6 and are automatically fixed electrical latches 29.

In Fig.7 shows agricultural equipment in the form of a steel plate 17 with holes 18 - used to form snow shafts, as shown in Fig.3, 4.

Figure 5 shows agricultural equipment 30 for loosening the soil, mounted on the plate 17. Loosening teeth can be in the form of flat knives, and also be round, square or elliptical in cross section; may be disk.

On Fig shows agricultural equipment for leveling the soil surface of agricultural lands. Steel plates 31 are fixed on the plate 17.

Figure 9 - agricultural equipment for loosening the soil with spring teeth 32.

Figure 10 shows agricultural equipment for the cultivation of rows of plants. On the rods 33, on both sides, two cultivating legs 34, 35 are symmetrically fixed.

Figure 11 shows two 36, 37 agricultural equipment for various purposes, mounted on a plate 17. When moving in the direction shown by arrow E, agricultural equipment 36, for example, agricultural equipment for soil preparation, works. The desired inclination of the shield 9 creates tension on the left ends of the chains 14. Agricultural equipment 37, for example, a seeder, is used when the agromost moves in the opposite direction along the same constant tracks 38. In this case, the desired inclination of the shield 9 is created by tensioning the other end of the chain 14. Caterpillars 4 are driven gearmotors 39.

Agromost works as follows.

To perform work on the ends of the shields 9 hang, for example, only the plate 17 for snow retention, while the shields 9 are fixed in a vertical position. The gap between the soil and the lower surface of the strip 17 is regulated by turning on the reversible gear motor 26, and the movement of the agromost along the snowy agro-year begins. When the snow shaft in front of the plate 17 and the shield 9 reaches a predetermined value, then using a reversible gear motor 12, the shield 9 is rejected, leaving the snow shaft behind, as shown in Fig. 4, then again put the shield in a vertical position to accumulate the next shaft.

When the agromost reaches the edge of the agricultural land, then, if necessary, the frames 6 are lifted to remove the working bodies of agricultural equipment from the soil, deploy the tracks 90 °, move to new tracks and, moving to another control cabin, lead the agromost in the opposite direction. If two agricultural equipment of various purposes are hung on plate 17, then along the same tracks they move back and forth, and only after that the agromost is transferred to new tracks.

The positive effect of the device is as follows.

- The design and cost of agricultural equipment hung on an agromost through standard plates 17 can be much simpler and cheaper than traditional ones.

- On the shield 9 of one frame 6, many agricultural equipment can be hung. Steel plates 17 are standard and may differ from one another only in height.

- Continuous frontal movement of the agromost from edge to edge of agricultural land, for example, during snow retention, leveling of the soil surface, loosening of the soil, occurs without a 180 ° turn of the farm and without a 180 ° turn of removable agricultural equipment, which significantly increases the productivity of the agricultural bridge.

- Unused agricultural equipment temporarily removed from the agro-bridge, hung on a suspension board 9, when stored for temporary storage, takes up significantly less space than traditional wheeled ones.

- Two different agricultural machines can be mounted simultaneously on the shield 9 of the agromost.
