Description

The device relates to the field of forestry and agriculture, namely to equipment for the formation of planting holes before planting seedlings and seedlings of forest and agricultural crops.

A device for planting plants is known (Description of the utility model to the patent RU 148183, declared on 07/02/2014, published on 11/27/2014), which includes a hollow body open at the upper and lower ends, a funnel and handles mounted on the upper end of the hollow body, rigidly fixed on at the lower end of the housing, a fixed blade and a rotary blade pivotally mounted on the housing, connected to a pedal and a mechanism for fixing the rotary blade, as well as an emphasis for inserting the blades into the ground. The hollow body is made in the form of horizontally oriented shells, located one above the other and rigidly connected by vertical posts.

The disadvantage of the known device for planting is the high complexity of work, due to the need to perform an additional operation to press the pedal to open the rotary blade.

A device for planting plants is known (Description of the utility model to the patent RU 121421, declared 03/11/2012, published 10/27/2012), including a pipe, the lower cone-shaped end of which has a shut-off valve, and handles are fixed on the upper end of the pipe on the semi-axes, and the opening mechanism drive gate valve in the form of a rod connecting the handle to the gate valve lever. The drive of the shutter valve opening mechanism is provided with an additional link connecting the other handle to the shutter valve lever and installed symmetrically with respect to the first link, and both handles are movable.

A disadvantage of the known device for planting plants is the high labor intensity of the work, due to the need to perform an additional operation by pressing the handles connected by a rod to the shutter valve lever to open it.

The closest in essence and taken as a prototype is the Pottiputki landing tube (Pottiputki landing tubes. -Electronic resource.- Access mode: http://pottiputki.com/ru/produkter-ror-rus/ (date of access: 07/05/2022)), including a pipe, in the upper part of which handles are made to hold it, and a shut-off valve is made in the lower part of the pipe. The gate valve is made in the form of one rotary jaw. A pedal for opening the shutter, as well as a rod for releasing the shutter from the open position, are attached to the rotary jaw of the shutter valve. A depth gauge is also installed at the bottom of the pipe.

The disadvantage of the well-known landing pipe "Pottiputki" is the high complexity of work when using it, due to the need to press the pedal to open the valve.

The technical result of the device for the formation of landing holes is to reduce the complexity of work when using it by providing automatic opening and closing of the shutter valve.

The technical result is achieved by the fact that in the device for forming landing holes, including a pipe with a gate valve, the gate valve is made in the form of two rotary jaws forming a wedge in the closed state, each of the rotary jaws is equipped with a side lever, a support platform is mounted at the free end of each lever, wherein each lever is provided with a rotation limiter, and a compression spring is installed between each rotation limiter and the outer surface of the pipe.

In FIG. 1 is a view of the device for forming the landing holes in the initial position before the formation of the landing hole (gate valve closed).

In FIG. 2 is a view of the device for forming the landing holes in the process of forming the landing hole (gate valve open).

The device for the formation of landing holes includes a pipe 1 with a shut-off valve, which is made in the form of two rotary jaws 2, 3. The rotary jaws have such a shape that, in the closed state, the edges of their side surfaces 4, 5 are tightly pressed against each other and form a wedge. Each of the rotary jaws 2, 3 is equipped with a side lever 6, 7 attached near the axis 8, 9 of its rotation. At the free end of each of the side levers 6, 7, a support platform 10, 11 is mounted. Each of the side levers 6, 7 is equipped with a rotation limiter 12, 13. Compression springs 15, 16 are installed between each rotation limiter 12, 13 and the outer surface of the pipe 1.

Works the proposed device for the formation of landing holes as follows. Pipe 1 is installed in a vertical position with the shut-off valve down. In this case, the gate valve is in the closed position - the edges of the side surfaces 4, 5 of the rotary jaws 2, 3 are tightly pressed against each other and form a wedge. Then they press on the pipe, as a result of which the gate valve is introduced into the soil 14. As the gate valve deepens into the soil, the support platforms 10, 11 rest against the upper soil layer with their supporting surfaces and through the side levers 6, 7 ensure the opening of the rotary jaws 2, 3. The opening of the rotary jaws 2, 3 occurs until the limiters of rotation 12, 13 come into contact with the outer surface of the pipe 1. In this case, the elastic deformation of the compression springs 15, 16 occurs. Then the pipe with an open gate valve is removed from the soil. In this case, under the action of elastically deformed compression springs 15, 16, the rotary jaws 2, 3 automatically close and form a wedge. The device is ready for the next cycle of operation.

Due to the fact that the gate valve is made in the form of two swivel jaws forming a wedge in the closed state, the device is easily introduced into the soil, and when the gate valve is opened, the swivel jaws opening will evenly shift the soil layers to the sides, thereby ensuring the vertical position of the device and the formation of a landing wells. Due to the presence of side levers on the swivel jaws with support platforms and rotation limiters, automatic opening of the swivel jaws as the device is deepened into the soil is ensured.

By the distance between the rotation limiters and the outer surface of the pipe, one can judge the degree of opening of the rotary jaws. The presence of compression springs installed between each slewing stop and the outer surface of the pipe will automatically close the swivel jaws into a wedge when the pipe is in a vertical position above the soil surface.

Thus, the totality of the claimed features will contribute to the achievement of the technical result, which consists in reducing the laboriousness of work when using it by providing automatic opening and closing of the shutter valve, depending on the depth of penetration of the device into the soil - operations that are performed manually in the prototype.
