Description

A LATERAL PROPULSION PLOW APPARATUS

Field of the Invention

The present invention relates to a soil tillage device that reduces the resistance of the soil to plowing by means of lateral thrusting, rather than the resistance of the entire surface to be plowed.

Background of the Invention

Plow is a farm tool for loosening and/or turning the soil before sowing seed or planting so that fresh nutrients are brought to the surface while burying weeds and crop remains to decay.

Plows in the state of the art have a moldboard with a share for digging and cutting the soil plowing by drawing the plow via a tractor while the share is submerged under the soil. Digging, cutting and loosening the soil with moldboard leads to a huge abrasion which eventually wears out parts of the plow contacting with the soil. Moreover, this also load up too much stress to the tractors increasing fuel consumption. Moreover, the high loaded stress can be only managed by expensive, high power tractors.

For reducing the abrasion, modern plows uses damping springs. However, using heavy weight plows and springs leads to a high compression to the soil which results in formation of compressed soil piles. Soil piles generates capillary water ways on the soil after plowing which causes that the water inside the soil is pumped from the bottom to the top of the soil. As a consequence, especially in arid and semi-arid regions, formation of evaporating is increase which leads to shrinking green spaces and deteriorating the environment and accelerating desertification frighteningly. As a consequence, there is a need for a soil tillage apparatus providing low compression to the soil and reducing the load on drawing vehicles in the state of the art.

There are countless numbers of well-known plows that depend in their performance on pulling and sweeping the entire soil surface to be plowed, and the use of spiral spring to protect the plows from deformation and bending, which led to the application of the maximum tension stress on the entire tractor and much fuel consumption , in addition to compacting the soil and activating the force surface tension and the flow of water from the bottom upward in the form of ascending rivers have led to a reduction in green areas and an acceleration to the desertification, especially in arid and semi-arid regions.

For this reason, the designers resorted to increasing the power of the mechanical engine and t consequent huge tractors and very heavy machines to loosen the soil on one side and to resist deformation and bending on the other side, which led to the manufacture of giant mechanical devices that were characterized by slow performance and very high costs that farmers could not afford .

Detailed Description

Embodiments of the present invention relates to a soil tillage apparatus (1) comprising at least three concentrically positioned wheels (2); a drive mechanism (3) for providing a rotational motion to the wheels (2); plurality of drill heads (4) provided on an outer surface of the wheels (2) for digging soil; plurality of scoops (5) provided on an outer surface of the wheels (2) for draining excess soil arising from the digging of drill heads (4) and forming a channel for each wheel (2); at least one plow (6) positioned behind the wheels (2). The plow (6) comprises a carrier bracket (7) wherein at least a part of carrier bracket (7) is for settling inside a formed channel, a horizontal share (8) at an end of the carrier bracket (7) for cutting at least a portion of the soil blocks formed between channels, a lateral push paddle (9) at the lateral edges of the horizontal share (8) for destroying the soil blocks by a lateral push.

Embodiments of the soil tillage apparatus (1) is for drawing by a vehicle such as a tractor. The soil tillage apparatus (1) also needs to couple with a rotary mechanism which is preferably a provided by the drawing vehicle to the drive mechanism (3). The drive mechanism (3) transfers the rotary motion to the wheels (2). Together with the rolling motion of the wheels, the drill heads (4) provided on an outer surface of the wheels (2) dig the soil and the scoops (5) drain the excess soil arising from the digging of drill heads (4). In this way, each wheel (2) forms a channel. The, a plow (6) provided behind the wheels (2), in other word positioned to the wheels at the side other than the drawing vehicle, destroys the soil blocks formed between the channels. The plow (6) comprises a carrier bracket (7) pulling a horizontal share (8) leading part of which is positioned on the channel base. Thus, the carrier bracket (7) extends from the horizontal share (8) along to the soil tillage apparatus (1) such as a chassis (C). That is why at least a part of the carrier bracket (7) is for settling inside a formed channel. When the soil tillage apparatus (1) moves forward, the horizontal share (8) cuts at least a portion of the soil blocks formed between channels such as one over four of the width of the soil blocks. On the other hand, a lateral push paddle (9) positioned at the lateral edges of the horizontal share (8) destroys the soil blocks by applying a lateral push.

On the contrary to the conventional plows, in embodiments of the soil tillage apparatus (1) digging and destroying the soil progress with different means. Digging the soil is done by the wheels (2) with the drill heads (4) and the scoops (5) which is specified for this task and thus very efficient for the digging activity. Moreover, since the plow (6) is not responsible for digging and only responsible for the partial cutting and lateral pushing of the soil blocks, resistance applied to the plow from the soil and total weight of the plows is significantly reduced. As a consequence of reduced resistance, deformation on the plow and the high power drawing vehicle requirements and fuel consumption of the drawing vehicles are decreased. Since the plow (6) only face with the soil blocks and provide a lateral thrust rather than work against the resistance of the entire cross-section of the soil surface as in conventional plows, stress applied to the plow (6) is significantly reduced (o = y. e (o: tensile stress, y: Young's modulus, s: strain modulus or deformation modulus)). Moreover, our experiment shows that the stress on the drawing vehicle is dramatically reduced such that for 190cm wide soil the tillage apparatus ( 1 ) with five wheels (2) reduces the load on the drawing vehicle by in between 87-90%. Furthermore, as a consequence of reduced weight of the plows, formation of compressed soil piles generating capillary water ways is prevented which saves water up to %80 especially in dry seasons. Thus, a sustainable irrigation without depleting natural resources and groundwater reserves is provided. In one embodiment of a soil tillage apparatus (1) which is applicable for all embodiments, the plow (6) preferably are made from mixture of low carbon steel with low manganese steel.

In all models of cultivation (1) everyone can use it drill heads (4) and scoops (5) are installed on the outside surface of the wheels (2) one after the other. Except for two consecutive drill heads (4) for step correction; Because if the scoops (5) start to drill, they only work for one turn, then the correction is done automatically so that the drill heads (4) continue to work)

In one embodiment of a soil tillage apparatus (1) which is applicable for all embodiments, scoops (5) comprises a serrated edge (5.3) to facilitate collecting the excess soil. The scoops (5) preferably are made from mixture of low carbon steel with low manganese steel.

In one embodiment of a soil tillage apparatus (1) which is applicable for all embodiments, the drive mechanism (3) comprises a transmission (3.1) for coupling with a drawing vehicle, a gear assembly (3.2), a shaft (3.3) laying inside the center of the wheels (2) to transfer a rotational motion to the wheels (2). In one embodiment of a soil tillage apparatus (1), the drive mechanism (3) is adapted to rotate the wheels (2) towards opposite of the pulling direction of the soil tillage apparatus (1) (opposite direction of the drawing vehicle). In other words, the drive mechanism (3) is adapted to rotate the wheels (2) towards the plow (6). In other words, the wheels (2) move rotationally and direction of rotational movement is other side the direction of movement of the plow (6). Thus, channel forming (digging and emptying the soil by the wheels (2) with drill heads (4) and the scoops (5)) performance is significantly increased.

In one embodiment of a soil tillage apparatus (1) which is applicable for all embodiments, the drill heads (4) are in the form of a conical teeth.

Deformation modulus in the tractor which is located in the rail of plow, wherein the higher the resistance of plow rail the greater the tensile stress. Therefore, they applied springs to reduce bending of the plow rail, but the tensile stress remained on the entire tractor. So, the present invention relates to locating the deformation modulus in the practical aspect of the stress law tp reduced the deformation modulus (plow rail here) by reducing soil resistance.

The location of the deformation modulus is determined in the practical aspect for the stress law (c = y. s)

G: tensile stress, R: youth coefficient, s: compression modulus or deformation modulus.

As a result, tensile stress was reduced by (70-80) % through designs that work a crevice in the soil followed by lateral thrusting to reduce the tillage resistance
