Description

The claimed technical solution relates to agricultural tools and is intended for agricultural work using walk-behind tractors with various mounted implements.

Known self-propelled means of small-scale mechanization (RU 31356U1, 08/10/2003, [1]). As in the claimed technical solution, the analogue [1] contains a connecting bracket for connecting to a walk-behind tractor. The connecting bracket is rigidly fixed to the longitudinal link.

At the analogue [1], the longitudinal link is equipped with plan washers and is made in the form of a ridge. A central holder, as well as a transverse beam with the ability to move in the longitudinal and transverse directions, are fixed on the longitudinal rod. Various agricultural working bodies join the mount holders.

Known layout module (RU 150902 U1, 03/10/2015, [2]). As in the claimed technical solution, the analogue [2] contains a frame on which the seat is fixed, slewing wheels and a brake device. The frame contains a bracket for attaching the module to the walk-behind tractor.

The brake device includes two friction elements and a pedal. The bracket for attaching the module to the walk-behind tractor is located in the rear of the frame. The frame also includes a hitch for using attachments.

Also known is the adapter AM-2 LLC Manufacturing Firm Means of Small Mechanization LLC (online resource https://pfsmm.ru/adapter/, 04/20/2019). As in the claimed technical solution, the analogue [3] contains a frame on which the seat, wheels, brake pedal with a braking mechanism and a trailed assembly are mounted. The adapter [3] can be attached to the bracket of the rotary mower by means of a trailer assembly.

The adapter [3] also contains a mechanism for mounting tools, a pedal for fixing the mounted mechanism, a lever for raising or lowering the mounted mechanism, and a footboard.

The specified analogue [3] is the combination of essential features the closest analogue of the same purpose to the claimed technical solution. Therefore, it is adopted as a prototype.

The technical problem, the solution of which is provided during the implementation of the technical solution, is the need to ensure the universality of the adapter for the walk-behind tractor.

At the analogue [1], the bracket is rigidly connected to the rod. In the analogue [2], the bracket is rigidly connected to the rear of the frame. The prototype [3] trailed node is made integral with the frame and has a complex structure.

The technical result provided by the claimed technical solution is to provide aggregation of a universal adapter with any type of walk-behind tractor.

The essence of the claimed technical solution lies in the fact that the adapter for a walk-behind tractor contains a frame on which a riding module is mounted, comprising a seat, wheels and a brake assembly. At the same time, the first coupling device is fixed on the front of the frame. It differs in that the first coupling device is removable in the form of a bracket with round and oblong holes.

The above essence is a set of essential features of the claimed technical solution, ensuring the achievement of the claimed technical result.

In special cases, it is permissible to carry out the technical solution as follows.

Oblong holes have different lengths and are made on the upper and lower shelves of the bracket.

The adapter preferably comprises a grass mowing unit with a second coupling device that encompasses the first coupling device and is fixed by a rod passing through the aligned openings of the first and second coupling devices.

Bearing blocks are predominantly mounted at the ends of the grass mowing unit.

The author of the claimed technical solution made a prototype of this solution, the tests of which confirmed the achievement of the technical result.

In FIG. 1 shows an adapter for a walk-behind tractor; in FIG. 2 - brake unit; in FIG. 3 - the first coupling device; in FIG. 4 - node for mowing grass; in FIG. 5 - connection of the first coupling device and node for mowing grass; in FIG. 6 - site for tillage; in FIG. 7 - the position of the springs on the site for tillage.

The adapter for the walk-behind tractor (Fig. 1) contains a driving module (2) mounted on the frame (1), a unit for mowing grass (3) and a unit for cultivating the land (4).

The frame (1) is made in the form of a metal bent channel (channel-shaped profile).

The ride module (2) contains a seat (5), wheels (6), a wheel support (25) and a brake assembly (Fig. 2). The brake assembly comprises a spring (7) connected to the pedal (8) and a horizontal rod (9). The rod (9) is fixed in the holes of the pedal (8) with the possibility of pressing against the wheels (6).

On the front of the frame (1), a first coupling device (10) is fixed (Fig. 3). The first coupling device (10) is removable in the form of a bracket containing round (11) and oblong (12) holes. In this case, the oblong holes (12) have different lengths and are made on the upper (23) and lower (24) shelves of the bracket. The position of the first coupling device (10) relative to the frame (1) is adjusted by fasteners (13). Unlike the prototype [3], this design allows you to replace the first coupling device (10) on the frame (1) or change its position.

The knot for mowing grass (3) (Fig. 4) has a U-shape and is intended for connection with a walk-behind tractor. The mowing unit (3) contains a second coupling device (14), which covers the first coupling device (10) and is fixed by a rod (15) (Fig. 5), passed through the combined holes of the coupling devices (10, 14). Bearing blocks (16) are installed at the ends of the grass mowing unit (3).

The unit for cultivating the land (4) (Fig. 6) is mounted on the rear of the frame (1) and is designed for coupling with a plow, hillers, potato diggers and other mounted equipment for cultivating and cultivating the soil. Said assembly (4) comprises a third coupling device (17), a rod (18) and a lever (19). The third coupling device (17) is provided with springs (20) (Fig. 7), designed to create traction in the direction of the earth.

Examples of specific performance.

Example 1. On the frame (1) mounted leg rests (21) (Fig. 2).

Example 2. Behind the seat (5) there is a trunk (22) for transporting small loads (Fig. 1).

Example 3. The oblong hole (12) of the upper flange (23) of the bracket has a shorter length than the oblong hole (12) of the lower flange (24).

The implementation of the proposed technical solution is not limited to the above examples.

Description of work and order of use.

The details of the driving module (2) are mounted on the frame (1). In this case, the wheels (6) are installed in the axles located on the wheel support (25), which is mounted on the frame (1) (Fig. 1).

A first coupling device (10) is attached to the front of the frame (1). The position of the first coupling device (10) is fixed with fasteners (13) (Fig. 3).

To the first coupling device (10) attach the node for mowing grass (3) (Fig. 3, 4). At the same time, the second coupling device (14) is placed on the first coupling device (10) and they are fixed between them by the rod (15).

To the rear of the frame (1) attach the unit for cultivating the earth (4). Using the rod (18), the lever (19) and the third coupling device (17) are connected to each other. On the third coupling device (17), the required implement for cultivating the soil is hung. Lowering and raising the mounted implements for tillage occurs by means of a lever (19).

The unit for mowing grass (3) (Fig. 4) is connected to the walk-behind tractor using bearing blocks (16). A mower (not shown) is installed on the walk-behind tractor.

The operator starts the engine of the walk-behind tractor and drives the device along the terrain, cultivating the soil. Braking is carried out by pressing the pedal (8). In this case, the rod (9) is pressed against the wheels (6) and brakes the adapter.

Industrial applicability.

The claimed technical solution is implemented using industrially produced devices and materials and can be applied at any agricultural enterprise and in personal subsidiary plots.
