Abstract

FIELD: agricultural engineering, in particular, hand-held tillage tools.

SUBSTANCE: working tool of hand-held furrower is made in the form of conical frame having lower and upper sides equipped with equally sized teeth, said teeth being laterally offset with respect to one another by value equal to half the tooth. Frame upper part is provided with rectangular slots and is movably connected with plate having detachable moldboard and holder formed as conical cylinder. Furrower of such construction allows planting, hilling, thinning and other seedling care operations to be performed by one worker.

EFFECT: simplified construction and reduced labor intensity.

Description

The invention relates to agriculture, in particular to hand tools for tillage.

Known hand tools, including a rectangular collapsible frame, consisting of two parts. The first part is the upper base with a handle in the form of a U-shaped bracket, at the opposite ends of which two cylindrical pins are installed inside. The second part is made in the form of a U-shaped blade with holes at the ends and mounted on the pins of the upper base, and the upper corners of the blade on the handle side have bevels to the centers of the holes. The bevel unit is 12-30 °, and the angle of inclination of the handle to the upper base is 55-60 °. For self-sharpening during operation, the blade is made of bimetal [1].

Also known is a hand tool designed for caring for crops, taken as a prototype, containing a working body fixed in a holder on the handle, made of a strip in the form of a box with sharpened lower and side sides. The holder is made in the form of a sleeve and has arched and rectilinear sections. On arcuate areas there are longitudinal slots. Flats are made on the handle. A longitudinal slot is made in the center between the flats. The wedge-shaped plate through the longitudinal slot of the holder is located in the slot of the end of the handle. At different ends of the handle are fixed working bodies with different working widths. A manual tool when moving away from itself produces idle movements above the soil [2].

However, both the first and second technical solutions require significant physical effort working and quite metal intensive.

The objective of the proposed technical solution is to reduce in relation to the prototype of the metal and the physical efforts of the worker.

The problem is achieved in that in a manual furrow containing a working body mounted on a holder made of a metal plate, the lower and sides of which are sharpened, according to the invention, the working body is made in the form of a cone-shaped frame, the lower and sides of which are sharpened on both sides in the form of equal-sized teeth, laterally displaced by 0.5 teeth relative to each other, and the upper part of the frame, equipped with rectangular cutouts, is movably connected to a plate equipped with a removable tvalnikom holder and formed in the shape of the conical cylinder and otvalnik formed of two equal plates forming an acute angle.

Supply of the proposed manual groove with a working body made in the form of a cone-shaped frame, the lower and lateral sides of which are equipped on two sides with sharpeners in the form of equal-sized teeth offset by 0.5 teeth relative to each other, movable connection of the upper part of the frame with the plate with a dump mounted on it and the holder allows you to declare the presence of such criteria of the invention as "novelty" and "inventive step".

Figure 1 shows a General view of the manual furrow.

Figure 2 shows a section of its horizontal part of the gear frame, made in the form of a removable multi-tooth knife.

Figure 3 shows a side view of the manual furrow.

The manual furrow consists of a cone-shaped frame 1 (Fig. 1), to which the plate 2 is attached. A removable dump 3 and the handle holder 4 are attached to the plate 2. The frame 1 (Fig. 1) has two rectangular grooves 5 (Fig. 3), in which plate 2 is inserted. This connection allows the frame 2 (Fig. 1) to swing when the furrow moves forward and backward, which ensures optimal tilt angles when working with the furrow. The handle holder 4 (FIG. 1) is a conical cylinder, inside of which the handle 6 is placed (FIG. 3). The cone-shaped frame is made with teeth 7 located on two sides of the plate, and the tops of the teeth have a mutual offset equal to 0.5 tooth division. Such a shift relative to each other of the teeth located on opposite sides of the conical frame 1 (figure 1), allows to reduce the physical effort exerted by working with the furrow, achieved due to a more uniform removal of soil layers when it is deepened. Removing part of the metal from the plate in the manufacture of equal-sized teeth on both sides of the plate can reduce the metal consumption of the device. Leader 3 (Fig. 1) is made of two identical metal plates forming an acute angle, which ensures cutting and dumping of the earth layer in different directions during the work of the furrow. Figure 2 shows the lower part of the frame, made in the form of a removable multi-tooth knife.

The operation of the device is as follows.

Prepared soil for planting, for example, potatoes is marked under the beds with a marker. Furrows for planting potato seeds are made a manual furrow. Potato seeds and fertilizers are placed manually into the furrows, after which the furrows are heaped up with earth. Weeding and hilling are subsequently carried out using a furrow, for which, when weeding, a dump with a conical frame equipped with equal teeth is removed from it, weeds are cut to a depth of 10-15 cm from the surface layer of the earth, moving the furrow to and from itself. When hilling the potatoes, they again put on the blade with two screws and make the hilling, making a furrow between the rows to a depth of 10-12 cm.

Thus, the use of the proposed technical solution allows one-person planting, hilling and weeding the cultivated crop with less physical effort, which is so necessary for people with physical disabilities.
