Description

The invention relates to agricultural engineering, in particular to devices for intrasoil application of liquid when watering plants and feeding plants, as well as for making holes when planting plants in nurseries, orchards and vineyards.

A device for hydrodrilling containing supply communications, a barrel with a nozzle, a sectional seal, radially arranged knife feathers (Author's certificate SU 1165253, A 01 C 5/04, 1985).

A disadvantage of the known device is the destruction of the walls of the hole in the process of drilling, accompanied by leakage of water through the gaps formed between the walls of the hole and the body of the hydraulic drill shaft, which led to low efficiency of making holes, reducing the effective pressure of the water head during operation.

Known hydrodrill containing a barrel and a handle connected to it with hoses for supplying water and compressed air. The barrel is equipped with a tip, in which holes are made for the subsoil supply of water and air (RF Patent, RU 2740805, A 01 C 23/02, 2021).

A disadvantage of the known device is the reverse ejection of water and air through the gaps between the walls of the hole and the shaft of the pneumohydraulic drill due to the destruction of the system of capillary pores in the walls of the well during its drilling in the insufficient efficiency of the devices in the irrigation mode, resulting in a decrease in the volume of moistened soil in the zone of plant roots. .

The technical task of the proposed invention is to improve the quality and efficiency of the process of making holes for planting, local irrigation or fertilization of the root layer of plants in arid conditions.

The stated technical problem is solved by the fact that the hydropneumatic drill, which includes a barrel with a handle to which hoses from water and air sources are connected, is equipped with a special stop in the form of a disk with a side, a ring of their dense elastic material, through which the disk is attached to the sleeve with a latch, which makes it possible the disk to fit snugly against the soil surface at different angles of inclination of the pneumatic hydrodrill shaft and at the same time act as a depth limiter.

The technical result is expressed in the fact that the pneumatic hydrodrill with a protective device, including a shaft with a handle to which hoses from sources of liquid and air are connected, according to the invention, is equipped with a protective device containing a sleeve with a lever mounted on the shaft of the pneumatic hydrodrill with the possibility of moving along it and rigid fixation on the barrel, a disk with a rim directed downwards, located on the outside, and a washer made of dense elastic material connecting the disk and the sleeve.

The invention is illustrated by drawings.

Figure 1 shows a diagram of a General view of pneumohydraulic with a protective device, where pneumohydraulic introduced into the soil perpendicular to its surface; in fig. 2 - the same, - the hydropneumatic drill is introduced into the soil at an angle to its surface; in fig. 3 shows a sectional view of the safety device.

The pneumatic hydrodrill with a protective device contains a barrel 1 with a tip, a handle 2, connecting fittings 3 and a protective device 4.

The pneumatic hydrodrill contains a barrel 1, a handle 2, a fitting 3 for connecting hoses from sources of liquid and air (hoses are not shown in Fig.) and a protective device 4.

The protective device 4 consists of a metal outer disk 5 with a side 6 located on the outside and directed downwards, bushings 7 with a lever 8 mounted on the shaft 1 of the hydrodrill with the possibility of moving along it and rigid fixation on the shaft 1, a wide washer 9 made of dense elastic material using a bolted connection 10 connecting the outer disk 5 with the sleeve 7. The sleeve 7 with the lever 8 is fixed on the trunk 1, for example, the bolt 11, at the desired height, limiting the degree of penetration. The use of washers 9 made of a dense elastic material, such as rubber, allows you to change the angle of inclination of the pneumohydraulic drill when it is introduced into the soil and firmly press the disk 5 with a side 6 to the soil surface. To facilitate the introduction of the pneumohydraulic drill into the soil, the operator can press the lever 8 with his foot, increasing the pressure on it and deepening the sides 6 of the disk 5.

The tight fit of the disc 5 with the side 6 to the soil does not allow liquids and air to escape from the treatment area.

The device works as follows.

Before starting work, the protective device 4 is fixed with a bolt 11 on the shaft 1 of the pneumatic gyroburr, thereby adjusting the depth of the hole.

For example, to feed trees at a distance of 20-25 cm from the trunk of a tree, the trunk 1 of a pneumohydraulic drill is inserted into the ground at an angle. After deepening it to the required depth, make sure that the disk 5 with the shoulder 6 of the protective device 4 fits snugly against the soil surface and water or liquid fertilizers or a water-air mixture are supplied into the hole, depending on the purpose. Due to the washer 9, the disc 5 with the rim 6 are positioned horizontally relative to the soil surface and tightly closed to the hole.

If necessary, together with the liquid, air is supplied for additional loosening and saturation of the root layer with oxygen.

In the case of using a hydropneumatic drill for making landing holes, the shaft of the hydropneumatic drill is inserted into the soil vertically down.

The use of a pneumohydraulic drill with a protective device in the operations of root feeding of garden plants will increase the pressure in the working area by 25-28%, improve the penetration of the working fluid or water-air mixture into the root layer. During hole making operations, liquid consumption is reduced by 25-37%, the quality and efficiency of hole making for planting, local watering or fertilizing the root layer of plants in arid conditions is increased.
