Description

The utility model relates to agricultural tools, namely, hand tools for tillage and digging tubers, and can be used for manually digging, loosening the soil and digging up various root crops, tubers in personal subsidiary plots.

The agricultural hand tool, the pitchfork, is widely known. Known garden forks designed for digging the soil and digging potatoes, beets, carrots and other tubers. The disadvantage is their recession in the soil when digging up various root crops, tubers in personal subsidiary plots.

The closest in purpose and technical essence is a hand tool (GB patent GB 2120511, CL А01В 1/00, 1983), consisting of a working body, in the form of teeth mounted on a bar and a support mounted on the bar at an angle to the teeth , the attachment point of the handle and the handle. The disadvantage of this hand tool is the narrow contact surface of the support, which leads to the drowning of the support in the soil during cultivation and the deterioration of working conditions.

Signs that coincide with the essential features of the declared decision are

 the presence of a working body in the form of teeth fixed on a bar;

 supplying a hand tool with a support;

 the ability to fix the handle on the working body through its attachment point.

The technical problem to which the utility model is directed is to create a reliable hand-held simple tool for soil cultivation and digging up tubers, which will facilitate manual labor and increase labor productivity when digging, loosening the soil and digging up various root crops and tubers.

The technical problem is solved in that the manual tool for tillage and digging up tubers contains a working body in the form of a bar with teeth, a support element, a attachment point for the handle and the handle, while the support element is made in the form of a hollow body consisting of front, rear and side walls , inside of which there is a partition connecting the front and rear walls of the hollow body, the front wall is connected by a bend to the attachment point of the handle and, by means of bends, is connected to the bar of the working body, and s wall support member are further provided with brackets that are fixed to the outer teeth of the working body. Holes may be made on the back wall of the hollow body.

Distinctive features of the claimed technical solution are the following features: the supporting element is made in the form of a hollow body, consisting of front, rear and side walls, inside which a partition is installed connecting the front and rear walls of the hollow body, the front wall is connected with the attachment unit of the handle and the bends by means of a bend welding is connected to the bar of the working body, and the side walls of the supporting element are additionally equipped with brackets that are mounted on the extreme teeth of the working element Ghana. Holes may be made on the back wall of the hollow body

The essence of the utility model is as follows. A hand tool for soil cultivation and digging up tubers, consisting of both a working body, the attachment point of the handle and the handle, is equipped with a support element made in the form of a hollow body consisting of front, rear and side walls, inside of which there is a partition connecting the front and rear walls and on the front the wall is bent. The hollow body, consisting of the front, rear and side walls is made of thin metal, has a small mass and is mounted on the bar of the working body, the attachment point of the handle and the extreme teeth. The area of the support when working with a hand tool is formed by the back wall of the hollow body, which does not sink into the soil when it comes into contact with it when the soil layer is raised or the tubers are dug up. A lever is created relative to the support, where the handle is the lever arm, approximately five times longer than the other lever arm - the teeth of the working body. More force is created on the short arm of the lever with less force on its long arm. This ratio of the lengths of the lever arms reduces the efforts when digging, loosening, digging tubers in proportion to their lengths. The partition connecting the front and rear walls of the hollow body gives it rigidity, which affects the strength of the hollow body, and, in general, the reliability of a hand tool for soil cultivation and digging tubers. The bend made on the front wall of the hollow body, allows you to fix it on the attachment point of the handle. The side walls of the support element are additionally equipped with brackets, which are also fixed on the extreme teeth of the working body to increase the strength of the tool. The brackets do not prevent the tool from entering the soil, as it is made with a bevel. The back wall of the hollow body may have additional holes for attaching additional elements that increase the area of the support, for example, made of plywood.

The design and operation of the utility model is illustrated by examples of its implementation using the following sketches: in FIG. 1 shows a front view of a fork with a support; in FIG. 2 is a side view; in FIG. 3 is a section AA of FIG. 1, in FIG. 4 - support assembly. A hand tool for soil cultivation and digging up tubers consists of the following elements: teeth 1, strap 2, forming a working body, support 3, made in the form of a hollow body, where the front wall 4, rear wall 5, side walls 6, partition 7, brackets 8 , bends of the front wall 9, the bend of the front wall 10, the attachment point of the handle 11, the handle 12, the holes of the rear wall 13.

The operation of the claimed utility model is as follows. The worker immerses the teeth 1 fixed on the bar 2 into the soil at an angle to the soil surface, for example, when digging up potato tubers, under a potato bush. He presses the foot on the top of the support 3 in the form of a hollow metal body, consisting of a front 4, a back 5 and side walls 6 with a partition 7. The support 3 is mounted on a bar with teeth by welding to it of the bends 9 of the front wall, on the extreme teeth using brackets 8, as well as a bend 10 on the attachment point of the handle 11. The hand tool is immersed in the soil to the bar. The hollow body of the support does not prevent the tool from entering the soil, as does not have a bottom. Then, when bending the shank 12 downward by hand, the plank with teeth rotates, and the tool rests on the entire surface of the back wall of the hollow body against the soil, lifting a layer of earth and taking out potato tubers. The partition connecting the front and rear walls of the hollow body increases the strength of the hollow body. On the front wall of the hollow body, a bend 10 is made necessary for fastening the support and the attachment point of the handle. The shoulder of the handle is approximately 1000 mm, the shoulder of the teeth is 180 mm, which reduces force by about 5 times during operation, in proportion to the difference in the lengths of the lever arm. In this case, the tool has a small mass, the supporting surface of the rear wall is 180 × 70 mm with a width of the side walls of 40 mm. In addition, two holes 13 are provided on the back wall of the hollow body of the support for attaching an additional element in order to increase the area of the support when working on loose sandy soil.
