The present invention relates to the structuring of a cultivator foot system (1), an agricultural implement, which ensures a more efficient performance of the foot system of the cultivator machinery functioning without tipping any soil during processes such as loosening the soil, plowing, and crushing the clods. Return spring hanger (2) included in the cultivator foot system structuring ( provides for equal distribution of the load on the return springs (9) as a result of the tensioning while the piston system (3) ensures absorbs the destroying force on the foot, chassis and foot caps during the resistance against the force exerted on the cultivator foot and the return of the force formed in the springs, thus avoiding breakages and ensuring a more efficient performance.

Description

CULTIVATOR FOOT SYSTEM STRUCTURING

Technical Field

The present invention relates to the structuring of a cultivator foot system, an agricultural implement, which ensures a more efficient performance of the foot system of the cultivator machinery functioning without tipping any soil during processes such as loosening the soil, plowing, and crushing the clods.

Return spring hanger as part of the cultivator foot system structuring provides for equal distribution of the load on springs as a result of their tensioning while the piston system absorbs the destroying force on the foot, chassis and foot caps during the resistance against the force exerted on the cultivator foot and during the return of the force formed in the springs, thus avoiding breakages and ensuring a more efficient performance.

Prior Art

Being an agricultural implement, a cultivator works the soil without tipping it. These are used in processes like loosening the soil, plowing, and crushing the clods. Processing parts of the cultivators consist of the cultivator foot and the plowshare.

The cultivator models that are currently used and produced today cannot accommodate to the current agricultural circumstances. Since fields are not fallowed as in the past, they are cultivated at least twice a year, and this causes the field to be squeezed and hardened during cultivation procedures. In general, cultivators use two springs. When two springs were not enough, four springs have been attached. The shaft was extended to attach the said four springs, causing a rise in the momentum and breakage of the shaft while attaching only two shafts did not apply equal force on four springs as their axis changed. The load always remains on the two springs and causes the springs to be broken. Furthermore, when the foot gets stuck on a hard ground or a stony ground during tillage, the foot rises and is stretched and when this stretching is over, the foot returns to its original position with the accumulated force of the four springs. The entire load produced with these stretching hits the foot, chassis and foot connection caps, damaging and breaking them. As a result, farmers cannot till the hard and stony fields as they desire.

The U.S. Pat. No. US 210 93 85 in the state of the art refers to an automatic cultivator foot. This system teaches a foot returning to its original position through two springs when there is an obstacle. When we examine the working principle of the document no US 2109385, it will be understood that it possesses a different structure than the cultivator foot mentioned in this document.

Another U.S. Pat. No. US 120 71 62 in the state of the art refers to a cultivator foot. When we examine the working principle of the foot system in the document no US 120 71 62, it will be understood that it possesses a different structure than the cultivator foot mentioned in this document.

The cultivator foot system structuring 1 of the invention comprises:

- caps 7 to which the cultivator foot 5, chassis 11 and piston body holder bolster Sc system are connected,

- cultivator foot 5 for tilling the field and plowshare 8 that introduces the cultivator foot 5 into the soil and allows it to work the soil,

- return springs 9 providing power for the cultivator foot system structuring 1,

- piston protection cover 4 that prevents accumulation of dust and earth in the shock-absorbing and sudden stress-blocking piston system 3 and that prevents it from crashing into stones during the tillage,

- attachment and detachment switch 10 for the return spring hanger apparatus

2,

- three rows of chassis 11 for the cultivator foot system structuring 1 to be mounted,

- return spring hanger apparatus 2 that ensures the equal tensioning of the return springs 9, that collects the tensioning in the desired center and that allows more return springs 9 to be mounted over the single shaft

- shock-absorbing and sudden stress-blocking piston system 3 that is connected to the piston shaft holder piece 6 through the foot connection center 3g and to the cap 7 through the piston body holder bolster 3c and that prevents the breakages by absorbing the force created in the springs following the resistance in the cultivator foot during the return of this force. The cultivator foot system structuring 1 with piston of the invention is designed with an extended cultivator foot to prevent the accumulation and blockage of the cultivator feet due to the deep tillage and loosening of the soil or accumulation of the corn and wheat stems and it includes three rows of chassis 11. The cultivator foot system structuring 1 comprises return spring hanger apparatus 2 and shock-absorbing and sudden stress-blocking piston system 3 to ensure a smooth performance on hard and stony soil and to allow deep tillage in the fields.

The return spring hanger apparatus 2 of the invention ensures equal tensioning of the return springs 9, collects the tensioning in the desired center, allows more return springs 9 to be mounted over the single shaft and can be integrated into many machines like this with a wide area of use.

The shock-absorbing and sudden stress-blocking piston system 3 of the invention uses a working system in which the oil inside it is replaced when the piston system shaft 3e is extended due to the rise of the cultivator foot 5 as shown in figure 2 and when the said piston system shaft 3e is contracted due to the lowering of the cultivator foot 5 through the considerably narrow gap created between the piston pipe and the oil chamber 3b and the piston pressure adjustment wedge 3d. This way, when the cultivator foot 5 crashes into a hard ground and stony ground during the tillage, the force first affects the shock absorbing and sudden stress-blocking piston system 3 and the force is minimized; after this, when the foot 5 rises upwards, the return springs 9 are stretched, and after the cultivator foot 5 gets over the stony or hard ground, the force accumulated on the springs 9 pulls down the cultivator foot 9 swiftly and this time, the shock-absorbing and sudden stress-blocking piston system 3 allows the foot 5 to return to its original position slowly by absorbing the force accumulated on the foot 5. However, when these four springs 9 are stretched and when this stretching is over, these springs 9 increase the load together with the foot 5 even more and crash into the cap 7 and this is repeated hundreds or thousands of time. This cycle leads to breakages on the foot 5, cap 7, spring 9, plowshare 8 and chassis 11 of the cultivator. The shock-absorbing and sudden stress-blocking piston system 3 is designed to prevent this and these kinds of failures. Additionally, this shock-absorbing and sudden stress-blocking piston system 3 covers a wide are of use and can be connected to soil processing machines like spring plough and spring chisel.
