Description

DESCRIPTION

HOEING MACHINE RUNNING ON SOLAR ENERGY THE RELATED ART

The invention relates to hoeing machines used in the field of agricultural machinery in hoeing and digging in small scale gardens, fields, and lands.

The invention, particularly relates to providing the energy required for operating said hoeing machines from solar energy, instead of fossil fuels.

THE PRIOR ART

Agricultural lands require cultivation, or in or in other words hoeing for the purpose of clearing unwanted weeds, ventilating the soil, and thus obtaining fertile products. Hoeing operation had been done by manpower until technological products and related systems were developed. With the developing technology hoeing machines are manufactured, which allow easier and quicker cultivation of soil.

In the prior art, hoeing machines are available which run on fossil fuel, gasoline, diesel, and electricity. The prior art applications run on gasoline, diesel fuels, and electrical energy. During operation of the hoeing machines that run on gasoline and diesel fuel, the wastes of combusted fossil fuels mix into soil and thus pollute the soil. This pollution directly affects the agricultural product grown in soil and makes the agricultural land infertile. On the other hand, hoeing machines that run on electrical energy are not preferred, since their fuel consumption is too high.

Since the prior art hoeing machines run on gasoline, diesel, and electricity are heavy, they cause deeper digging operations, which leads to the possibility of cutting roots of trees. Moreover, the use and manoeuvrability of the prior art machines may be limited. Another disadvantage of the hoeing machines used in the prior art is not being able to replace blunt special blades, since the cutting special blades are integrated to the special designed rotating table. As a result, either the part of the soil that corresponds to the blunt blade isn't cultivated properly or the special designed rotating table containing the special blades is required to be replaced completely.

In the patent research made about the prior art, a utility model document with No. 2010/00588, entitled: "A suspension embodiment for preventing shocks on a hoeing machine" relates to "A hoeing machine making use of motor power for moving trailers or using the same as a vehicle and mechanisms that prevent shocks and vibrations when the hoeing machine pulls the trailer, and it comprises a suspension mechanism positioned between the wheel axle connection and hoeing motor gearbox in order to prevent breaking, bumps, and vibrations on the hoeing machine that pull the trailer and the connection areas thereof in bumpy and rough roads."

The above mentioned machine according to the invention also runs on fossil fuel. The above said drawbacks and the inadequacy of the prior art solutions about the subject have necessitated an improvement in the related technical field.

PURPOSE OF THE INVENTION The invention relates to a hoeing machine, which meets the above said requirements, eliminates all of the drawbacks, and brings some additional advantages.

The main purpose of the invention is to run hoeing machines on solar energy so as to produce an environmentally friendly hoeing machine by preventing the pollutant gas emission from hoeing machines that run on fossil fuels.

The purpose of the invention is to produce the cutting special blades that cultivate the soil in a modular manner, independent of the special designed rotating table, so that when any of the special blades are required to be replaced, the malfunctioning blade can be replaced locally without interfering with the other special blades. Another purpose of the invention is to produce the special designed rotating table, on which the cutting special blades are mounted, of a strong polymer plastic material, so that prevent it from rusting and ensure that it has high strength against impacts.

Another purpose of the invention is to allow performing machine, seeding, when desired, by means of mounting a seed spreading and plug mechanism thereon.

Another purpose of the invention is to ensure operation without shaking the user during hoeing by means of absorbing the vibrations via the suspension system.

Another purpose of the invention is to allow digging depth is adjustable.

Another purpose of the invention is to allow the hoeing machine to use solar energy during operation as well as storing solar energy in a battery when not in use. The structural and characteristic features of the invention and all of its advantages shall be understood better with the figures and the detailed description given below in reference to the figures, and therefore, the assessment should be made by taking into account the said figures and detailed explanations.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the preferred embodiments of the hoeing machine (A) according to the invention are only disclosed for better understanding of the subject without forming any limiting effect.

Figure-1 , Figure-2, and Figure-3 are perspective views of the hoeing machine (A) running on solar energy according to the present invention. The hoeing machine (A) according to the invention, in general terms, comprises a solar panel (1 ) that converts solar beams into electrical energy and a battery (2) that stores the electricity obtained from said solar panel (1 ) both for use in 12v direct current motor (10) and for storage purposes when not in use. This system comprises suspension, wheels (3) that allow movement of the system, both while in use and not in use, a framework forming the body, and a suspension system (7) integrated into this framework. The height adjustment of said hoeing machine (A) for different users is made by means of a telescopic height adjustment lever (8). Soil cultivation is made by means of the special designed rotating table (5) through the cutting special blades (4) mounted thereon, with the rotating motion originating from the electric motor (9) and gearbox. The speed of the hoeing machine (A) is controlled by the electronic circuit motor speed control arm (9) connected to the electric motor (10).

Figure 4 shows a perspective view of the modular cutting blade (4) that can be replaced in the hoeing machine (A) running on solar energy according to the invention. Said cutting blade (4) is made of sharp edged stainless steel having a 120 degree angle. In general, there are 7 of these special blades on a special designed rotating table. Connection holes (5.2) are found on the cutting blade (4) for bolt coupling.

Figure 5 shows a general view of the special designed rotating table (5) of the hoeing machine (A) running on solar energy and the modular special blades (4) mounted on said special designed rotating table. Said special designed rotating table (5) is the component which allows connection of the cutting special blades (4), on which the rotating motion originating from the electric motor (10) and the gearbox is made, and which makes rotating motion for digging operation of the special blades (4). It is made of hard plastic. It has stainless structure and it is durable up to 260 degree temperature. Blade guards (5.1 ) are found on the plastic special designed rotating table (5) that allow connection of at least 7 special blades. Moreover, blade connection holes (5.2) are found all along the special designed rotating table (5) to allow mounting of said special blades (4). It comprises blade strut (5.4) for physical leaning of special blades (4) against counter forces formed during hoeing operation.

Figure 6 shows a general view of the seed spreading mechanism (12) of the hoeing machine (A) running on solar energy according to the invention. This system is used when desired and can easily be removed from the machine (A) at other times. Said system can be modularly attached to and removed from the hoeing machine (A), when desired, by means of coupling bolts. By means of being driven with the drive component (12.2) positioned thereon, the motion is transferred to the seed spreading disc (12.1 ) via a shaft (12.3). The seeds that fall into seed dropping space (12.1 .1 ) reach the soil through the seed dropping pipe. Afterwards, the seeds are covered with soil via the plough (13). Moreover, since the drive component (12.2) used is an electric motor, the motor speed can be adjusted on the electronic circuit and thus the seed spreading frequency can be increased or reduced. The operating principle of the hoeing machine (A) according to the present invention is as follows:

First of all, electrical energy generated via the solar panels (1 ) reach the battery (2) and converted to direct current by means of the circuit components found therein and then transmitted to the electric motor (10). The drive originating from said electric motor (10) is brought to desired speed by means of the gearbox (14). Said gearbox (14) comprises plastic gears that are durable against rusting and dust formation. The gear has three levels. The gearbox (14) output shaft is connected to the special designed rotating table (5) via coupling and thus the motion is transferred to the special designed rotating table (5) made of plastic. Afterwards, soil is cultivated by means of cutting special blades (4) mounted on the special designed rotating table (5) and having a 120 degree angle. Said cutting special blades (4) are modular and in case of a malfunction, the malfunctioning blade (4) can be removed locally from the special designed rotating table (5) and replaced. Moreover, during operation of the hoeing machine (A), the suspension system (7) absorbs the vibrations and thus the user does not get tired.
