Description

 Refers to agricultural machinery.

 Known devices in which the conduit is used simultaneously and as a guide rail along which wheels or tracks of the agromost move, for example, according to the patent of the Russian Federation 2087085, 2134937, 12134938 - all classes A 01 B 48/00.

 Aggregates are known whose wheel hubs have supports on both sides, for example, according to the patents of the Russian Federation 2075271, 2134939 - A 01 B 49/00.

Aggregates are known on the farm of which various agricultural machines can be mounted, for example, combine harvesters that do not have circles for turning them through 180 ^o to perform work when the agromost goes in the opposite direction, for example, according to RF patent 2161387 A 01 B 49/00.

 The agromost is known, which with the help of vertically moving rods can capture frames with agricultural equipment fixed to them, while the height of the agricultural equipment relative to the cultivated soil is regulated by the same rods - according to the patent of the Russian Federation 2161386, A 01 B 49/00.

 A known method for the automatic movement of the agromost with leveling the front of its spans along a system of reference frames fixed, for example, on wires and interacting with sensors fixed on supporting carts, for example, according to RF patent 2128414, A 01 B 49/00.

The closest agromosts to the claimed are the agromost according to the patent of the Russian Federation 2097954, which can be rotated 180 ^o at the end of the farm using an auxiliary rod, the end of which is fixed to the head of the bench mounted on the soil, as well as the second prototype, a close analogue of the patent RF 2160517, A 01 B 49/00. This aggro-bridge is characterized in that its self-propelled carts have rubber-metal tracks with each track drive with two chains connecting the sprockets at the ends of the axles of the track drive rollers with a gear motor with two sprockets at the output. Caterpillars are fixed on reversal circles and can turn in both directions after two jacks fixed on each trolley lift the caterpillars above the ground. The agromost can move from one farmland to another, having previously turned all the tracks 90 ^o .

The disadvantage of both agro-bridge prototypes is that they rotate 180 ^o with the subsequent installation of the wheels or tracks of the head trolleys on a rigid support pipe in order to perform work, going in the opposite direction on the other side relative to the support pipe, it takes a lot of time, which reduces performance of aggro-bridges.

The goal is to reduce the time required to rotate the agromost 180 ^o , in order to continue to perform work while moving the head cart of the agromost along the support pipe in the opposite direction; increase productivity agromosta.

 The possibility of achieving the goal is ensured by the fact that the wheeled or tracked agromost has a jack fixed on the head self-propelled cart, above the guide rail, with possible support on the rail, for example, above the supporting water supply pipe fixed on agricultural land.

 Figure 1 - diagram of low-span agromost on wheeled or tracked traction moving along a guide made in the form of a water supply pipe.

In FIG. 2 is an end view of the simplest wheeled agromost with agricultural equipment fixed on the farm without 180 ^o rotation circle of agricultural equipment.

 Figure 3 is a front view of the wheel of the head self-propelled cart of the agromost, equipped with an additional disk with a guide rim.

 Figure 4 is a view of the agromost with self-propelled carts on rubber-metal tracks equipped with an additional jack for turning the farm of the agromost with support on the water supply pipe.

 5 is a view of a rubber track on a support pipe.

 Figure 6 is a view of the support plate of the jack on the support pipe.

 In Fig.7 is a diagram of the turns of the agricultural bridge on farmland.

 The agromost has a farm 1 with implements mounted on it 2 / shown by a dotted line /, self-propelled carts with wheels 3 or tracks 4 moving along the constant tracks 5, and one 6 permanent track, located under the head cart of the agromost, is a pair guide and at the same time water supply time.

 Wheel agromost / Fig. 1, 2, 3 / has a jack 7 fixed above the support pipe 6. The jack has a support plate with a thrust bearing 8 and a steering wheel 9. The drive of the wheels 3 is made from the micro gear 10 through the universal joints 11, 12 and wheel gears 15.

 Caterpillar agromost - Figures 4, 5, 6 - has a gear motor 14 for each caterpillar, each of which has two output sprockets 15 that rotate drive rollers 17 through two chains 16.

 Each caterpillar agro-bridge trolley has a common gear motor 18, which through the chains 19, 20 can deploy the tracks in both directions. The track reversal occurs after the common gear motor 21 lifts the carriage with jacks 22, 23 through chains 24, 25. The track reversal allows the agromost to be moved to other agricultural lands.

In order to be able to quickly rotate the aggro bridge 180 ^{o, the} head carriage of the caterpillar agro bridge has an additional jack 26 fixed in the middle between the tracks above the pipe 6 and acting from the gear motor 27. The aggro bridge has a water distribution pipe 28 with sprinkler nozzles 29, a cab 30, a gear motor 31, which through the chain 32 and sprockets 33 moves vertically the rods 34 with grippers 35 at the ends.

 All track rollers are mounted on frames 36. The rubber protectors 37 of the tracks of the head self-propelled carts have a longitudinal channel according to the width of the support pipe 6, the channel being reinforced with U-shaped brackets 38 open at the bottom, the crossbeams of which are fastened with rivets 40 to plates 41 through the reinforcing cord layer 39, 41 the teeth of which interact with the drive rollers 17.

 On the pipe 6, vertical plates 42 are welded at equal intervals, the edges of which are fixed in the vertical slots of the short sleepers 43, which prevents the possibility of longitudinal and transverse shear of the pipe from the loads of the moving agromost.

 44 marks a double drum for rolling and winding a water supply hose, the end of which is connected to valves that take water from the pipe 6, and an electric supply cable, the drum of which is frictionally connected to the water supply hose drum and rotated by a reversible gear motor 45. An additional disk is marked with a number 46 wheels 3 with a guide rim 47.

 Agromost is used as follows.

It moves along the farmland, as shown by the arrows in Fig. 7, performing the planned work, reaching the edge of the farmland, the agromost stops, raises the agricultural machinery buried in the soil, lowers the jack 7 or 26 onto the pipe 6, lifts the head trolley and, turning on the gear motors 14 on the other bogies, on its own moves to the other side of the pipe 6, relying on the thrust bearings of the jacks and deploying the farm 1 at 180 ^o . After this, the agromost can return back, performing work fixed on the farm by agricultural equipment that does not have circles for their 180 ^o turns.

The positive effect of the device is as follows:
- relying on the thrust bearing of the jack of the head trolley, the agromost can quickly move to the other side of the support pipe, thereby doubling the processing area, increasing productivity;
- agromost can perform all seasonal work in the presence of only one span and the minimum number of plumes of agricultural equipment; as far as possible, the user can add the number of spans and accordingly add the number of agricultural equipment;
- the absence of the need to have reversal circles under each mounted implement significantly simplifies the design and reduces the cost of agromost; the presence of a support pipe eliminates lateral displacements of the agro-bridge, which, if there is an appropriate electrical circuit, allows you to turn it into an agro-bridge when performing many agricultural operations;
- caterpillar agromost, unlike a light, but at the same time cheaper agromost, can perform all seasonal agricultural work, moving frontally; the turn of the tracks allows him to independently switch from one farmland to a remote second.
