Description

The invention relates to the field of agriculture, in particular to agricultural equipment and tools, and is intended for digging potatoes and other root crops.

A known tool for the extraction of weeds and / or weeding and a method for extracting weeds and / or weeding [1]. The weed extraction tool contains two teeth fixed on a common handle, immersed in the soil around the weed. One tooth is smooth, and on the other there is at least one hook-shaped protrusion, bent from its free end into the space between the teeth. With this hook-shaped protrusion, the weed is pierced or hooked to the root, and then the tool is simultaneously turned, tilted and pulled out of the soil.

The disadvantages of this technical solution are:

- low efficiency and productivity of collecting potatoes or other root crops;

- great effort is required in the production of work.

The closest technical solution is a device for digging and loosening the earth [2]. The device comprises a lever mechanism, a working body with a handle, a return spring, a movable mechanism consisting of a frame with wheels rotating around an axis.

The disadvantages of this technical solution are:

- low efficiency and productivity of collecting potatoes or other root crops;

- Requires large labor costs in the production of work.

The purpose of the invention is to increase efficiency, reduce physical stress on the operator when digging potatoes or other root crops.

This goal is achieved by the fact that the device for digging potatoes and other root crops (Figs. 1, 2, 3), including a lever mechanism and a working body with a handle, the working body is a truncated rod half-cone, consisting of rods of circular cross section with openings and narrowed truncated part, oriented down to the ground. The working body is connected to a telescopic handle, which is inserted into the pipe. The telescopic handle in the pipe is free and can move along its length and rotate around its axis. A clutch is installed on the telescopic handle, fixing the depth of the working body h. A return spring of length B is installed between the pipe and the coupling. Thus, by pressing the foot on the working body, it is buried in the ground to the depth of installation of the coupling. Next, the operator is using a lever mechanism, that is, a telescopic handle that rests on a supporting and mobile mechanism, raises the ground with potatoes and rotates around the axis. The working body is attached to the telescopic handle by means of a vibration nozzle consisting of a torsion spring and a cylindrical nozzle, so that the end of the telescopic handle is located inside the vibration nozzle and abuts against the working body. Thus, during rotational movements, the working body vibrates strongly, which greatly enhance the efficiency of the work. The earth wakes up through the air, and potatoes or other root crops remain in the working body. Separated potatoes are sprinkled to the side, the process of digging continues. The end of the telescopic handle, placed inside the torsion spring, prevents the vibration nozzle from bending, and it performs only rotational movements.

The telescopic handle can be lengthened by moving the handle and thereby increase its shoulder, which will facilitate the work of the operator. The working body is a truncated rod semi-cone, consisting of rods of circular cross section, with shame, and a narrowed truncated part, oriented down to the ground. To facilitate the pressing of the working body into the ground, the rods are pointed. The width of the working body a depends on the nature of the work performed. The width of the gaps between the rods at the working body is 30 ÷ 80 mm and depends on the size of the potatoes and other root crops being dug up. The diameter of the rods of the working body is 8 ÷ 12 mm.

The length of the vibrator is 80 ÷ 120 mm and depends on the size of the working body. So, for working bodies with a gap width of 60 ÷ 80 mm, the length of the vibration nozzle is 120 mm, with a width of the gap 30 ÷ 50 mm, the length of the vibration nozzle is 80 mm.

Figure 1 shows a device for digging potatoes, General view; figure 2 is the same, a top view; figure 3 shows a device for digging potatoes with a buried shovel in the ground, General view; figure 4 - working body, General view; figure 5 - node A in figure 4.

The device for digging potatoes consists of a working body 1, consisting of rods 2 for digging and loosening the earth 3. The working body 1 is connected to a telescopic handle 4, which is inserted into the pipe 5. A coupling 6 is mounted on the telescopic handle 4, fixing the depth of the working body 1 Between the nozzle 5 and the clutch 6, a return spring is installed 7. The supporting and movable mechanism consists of a frame 8 with wheels 9. The telescopic handle 4 can be extended by moving the handle 10. The working body 1 is connected to the handle 4 with vibration nozzle 11. The vibration nozzle 11 consists of a torsion spring 12, inside of which there is an end of the telescopic handle 13. The torsion spring 12 is rigidly attached to the cylindrical nozzle 14, which is rigidly attached to the handle 4 by means of fasteners 15.

A device for digging potatoes works as follows. The working body 1 is connected to a telescopic handle 4, which is inserted into the pipe 5 (Fig. 1, 2), of the working body 1, consisting of rods 2. The working body 1 is a truncated rod half-cone, consisting of rods of circular cross section with shame and narrowed the truncated part, oriented downward to the ground 3. The telescopic handle 4 in the pipe 5 is free, can move along its length and rotate around its axis. On the telescopic handle 4 mounted clutch 6, fixing the depth h of the depth of the working body 1 (figure 1). A return spring 7 of length B is installed between the nozzle 5 and the clutch. Thus, pressing the working body 1 with his foot, he digs into the ground 3 to the depth of the clutch 6. The operator then uses a lever mechanism, that is, a telescopic handle 4, which is supported by a supporting and movable mechanism, raises the ground with potatoes or root crops and rotates around an axis.

The working body 1 is attached to the telescopic handle 4 using a vibrating nozzle 11, consisting of a torsion spring 12, a cylindrical nozzle 14 and fasteners 15 (figure 5). Thus, during rotational movements, the working body 1 vibrates strongly, which greatly enhance the efficiency of the work. The earth wakes up through the air, and potatoes or other root crops remain in the working body. Separated potatoes are sprinkled to the side, the process of digging continues. The end of the telescopic handle 13 is placed inside the torsion spring 12, which prevents the vibration nozzle 11 from bending, and it performs only rotational movements.

The supporting and mobile mechanism consists of a frame 8 with wheels 9.

The telescopic handle 4 can be lengthened by moving the handle 10 and thereby increase its shoulder, which will facilitate the work of the operator.

To facilitate the pressing of the working body 1 into the ground 3, the rods are pointed. The width of the working body 1 a depends on the nature of the work performed. The width of the gaps between the rods 2 at the working body is 30 ÷ 80 mm and depends on the size of the digged potatoes and other root crops. The diameter of the rods 2 of the working body 8 ÷ 12 mm (figure 4).

The proposed technical solution has a wide range of applications, more efficient than analogues and is more economical.
