RU2459396C1 - Manual tillage device - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: device comprises a U-shaped bracket, on which the blade and the cutout for the cylinder are made. On the end parts of the cylinder there are holes and slots. Through the holes and slits made in the cylinder and through the cutout made in the U-shaped bracket the pins to secure the U-shaped bracket relative to the cylinder are mounted. The cylinder is made with the ability to move along the cutout of the bracket relative to the pins installed in the cylinder. The guide for mounting the shank is rigidly attached to the cylinder.

EFFECT: device enables to adjust smoothly the depth of the soil tillage and the slope of the blade relative to the shank taking into account the height of a man.

Description

The invention relates to agriculture, in particular to implements for tillage and cutting weeds.

Known manual tool [RU 2315454 C1, A01B 1/00 (2006.01), A01B 1/02 (2006.01), 01/27/2008] containing interchangeable canvases of a shovel or pitchfork with stops for legs and a wooden handle mounted on an arm. The proposed tool allows you to use it in the form of a shovel, pitchfork and grass cutter. However, this implement is not equipped with a depth gauge for tillage.

Known manual tillage implement (plane cutter) [RU 2201047 C2, 7 A01B 1/08, 03/27/2003], which is equipped with a device for adjusting the inclination of its blade relative to the axis of the handle depending on the height of the worker. However, this tool does not have the ability to control the depth of tillage.

Known garden tools [US 134062 A, cl. A01B 1/08, 05/18/1920], having a working body in the form of an elongated cone with a bent end, to which the handle is attached. However, the functionality of this tool is limited by pulling weeds when working with an elongated cone in the horizontal plane and deep loosening of the soil when working in a vertical plane. This device does not allow you to adjust the depth of tillage.

The objective of the invention is the creation of a device that allows you to process the soil with smooth adjustment of the depth of processing and tilt of the blade, taking into account human growth.

To solve this problem, a manual tillage device is proposed, which consists of a U-shaped bracket 1, on which blades 2 and a cutout 3 are made for cylinder 4, on the end parts of which are holes 5 and slots 6 for a stud (or bolt) 7, fastening the cylinder 4 with the bracket 1 through the holes 5. The stud (or bolt) 8 is designed to fix the U-shaped bracket 1 relative to the cylinder 4 through the slots 6. In addition, the guide 9 is rigidly attached to the cylinder 4 for fixing the handle 10 in it by any known method, for example using wines Comrade 11 (see figure 1). For the assembly of the U-shaped bracket 1 and cylinder 4 with pins 7 and 8, nuts are provided that are screwed onto the pins 7 and 8 and washers placed under the nuts.

A manual tillage device is brought into operation as follows. The inclination of the handle 10 (see figure 1) relative to the U-shaped bracket 1 with blades 2 is set taking into account the growth of a person by loosening the nuts on the studs 7 and 8 by smoothly turning the U-shaped bracket 1 in the slots 6 by the required angle so that the blade 2 easily buried, and the load for humans was minimal. The depth of the soil treatment is changed by unscrewing the nuts on the studs 7 and 8 and then moving along the notch 3 brackets 1 relative to the studs 7 and 8 installed in the cylinder 4. After setting the manual tillage device, tighten the nuts on the studs 7 and 8.

When moving the manual tillage device behind the stalk 10, the soil is cut with a blade 2 and passed between the blade 2 and the cylinder 4. When the blade 2 is dull on one side of the U-shaped bracket, the blade 2, located on the other side of the U-shaped bracket 1 by turning U-shaped bracket 1 relative to the cylinder 4 with the handle 10 fixed therein.

The proposed manual tillage device allows you to smoothly adjust the depth of processing, as well as the inclination of the blade 2 relative to the handle 10, which ultimately reduces the cost of physical labor for various types of tillage.
