RU115145U1 - MANUAL DEVICE FOR SOIL TREATMENT - Google Patents

Abstract

A manual device for tillage, containing a pitchfork with a cross member, on which a holder is rigidly fixed, pivotally connected through a horizontal axis to a support rigidly connected to the frame, the front part of which is connected to the rippers and bent upwards, and the rest is located in the same plane with the support, characterized in that the rippers are fixed on the jumper, which is installed on the front of the frame and is removable.

Description

Manual device for tillage.

The utility model relates to garden tools and can be used for digging and loosening the soil while removing weeds.

For manual digging of small plots of land, a shovel and a rake are most often used, which makes labor both inefficient and heavy. In addition, the overturning of the earth, which occurs in this case, reduces the fertility of the soil.

Known manual device for tillage containing forks with a cross member on which a holder is rigidly fixed, pivotally connected through a horizontal axis with a support rigidly connected to a frame equipped with cultivators.

(See certificate RU No. 6965 for the utility model "Shovel" MPK-6 А01В 1/02, decl. 1997.05.06, publ. 1998.07.16).

However, the design of the known manual device does not allow you to remove the rippers if you need to use the device for digging, which does not require loosening, which limits its operational capabilities.

The closest in technical essence and the achieved effect and selected as the closest analogue is a manual soil cultivating device containing forks with a cross member, on which a holder is rigidly fixed, pivotally connected through a horizontal axis with a support rigidly connected to the frame, the front part of which is equipped with cultivators and bent up, and the rest is located in the same plane with the support.

(See RF patent for utility model No. 85289 IPC А01В 1/20, application. 2009.03.23, publ. 2009.08.10 “Hand-held device for tillage”)

However, the design of the known device also has a drawback, which is due to the fact that the rippers are rigidly connected to the side of the frame bent upwards and cannot be removed, which limits the performance of the device.

The objective of this utility model is to increase the performance of the device for tillage, expanding its functionality.

The technical result that allows us to solve the problem is to provide the possibility of removing rippers by attaching them to the jumper, which is removable.

This object is achieved by the fact that in the known manual device for tillage, comprising forks with a cross member, on which a holder is rigidly fixed, pivotally connected through a horizontal axis with a support rigidly connected to the frame, the front part of which is connected with cultivators and bent up, and the rest the part is located in the same plane with the support, according to a useful model, the rippers are mounted on a jumper that is installed on the front of the frame and is removable.

Studies on patent and scientific and technical sources indicate that the proposed manual device for tillage is unknown, and, therefore, meets the criterion of "novelty."

The proposed manual device for tillage can be manufactured at any enterprise specializing in this industry, as this requires well-known materials and standard equipment widely produced by domestic and foreign industry.

Thus, the claimed manual device for tillage meets the criterion of "industrial applicability".

The proposed set of essential features informs the claimed hand-held device for tillage of new properties that can solve the problem, namely, improving the performance of the device for tillage and expanding its functionality.

Fixing the cultivators to the jumper, which is mounted on the front of the frame and is removable, allows you to remove the cultivators without much effort when using a soil cultivation device in which only digging is required and no cultivation is required, and re-install if necessary while simultaneously digging, which increases the performance of the device as a whole and expands its functionality.

The proposed useful is illustrated by drawings:

Figure 1 is a side view of a hand-held device (without a handle)

Figure 2 is a General view of a hand-held device in a perspective view (without a handle).

A manual tillage device comprises forks 1 with a cross member 2, on which a holder 3 is rigidly fixed, pivotally connected through a horizontal axis 4 to a support 5, rigidly connected to a frame 6, the front part of which is connected to the cultivators 7 and bent up, and the rest is located in the same plane with the support 5, the rippers 7 are mounted on the jumper 8, which is installed on the front of the frame 6 and is removable.

The manual device operates as follows:

Option I - for tillage with simultaneous digging and loosening (usually in spring):

A manual tillage device is installed vertically on the cultivated soil with pitchfork 1, then, while pressing with the foot simultaneously on the crosspiece 2 of the pitchfork 1 and on the side of the frame connected to the support 5, while the frame 6 deviates from the vertical position, the forks are immersed in the soil. Further, by the force of the hand applied to the handle (not shown in the drawing), the forks 1 are turned around the axis 4 and the earth is turned out, which is passed through the rippers 7, mounted on the cross-beam 8 and destroy it. Rearrange the device on an untreated soil and repeat the movement. The result is a strip of dug up and loosened soil freed from weeds.

Option II - when cultivating the soil without loosening (more often in the fall): first remove the cross member 8 with cultivators 7 from the front of the frame 6 and then the procedure is as follows:

A manual tillage device is installed vertically on the cultivated soil with pitchfork 1, then, while pressing with the foot simultaneously on the crosspiece 2 of the pitchfork 1 and on the side of the frame connected to the support 5, while the frame 6 deviates from the vertical position, the forks are immersed in the soil. Further, by the force of the hand applied to the handle (not shown in the drawing), the forks 1 are turned around axis 4 and the earth is turned out. Rearrange the device on an untreated soil and repeat the movement. The result is a strip of dug up soil.

If it is necessary to carry out tillage with loosening, the cross member 8 with cultivators 7 is again, without much effort, mounted on the front of the frame 6.

Conventional bolted connections can serve as fasteners for the cross member 8 to the frame 6, or the shape of the cross member 8 itself can secure it to the frame 6, as well as to remove it from the frame.
