Description
QUICK SET VARIABLE SCRAPER PRESSURE COUNTER ASSEMBLY
Field of the Invention:
This invention relates to a piece of agricultural machinery and more particularly, to a plurality of coulter assemblies attached to a tool bar; the improvement being a scraper which is adjustable to exert varying pressure on a coulter disk.
Background:
Farming in the prairies of North America is quickly moving to working the land with equipment that produces less soil disturbance. Reduced soil disturbance is proven to reduce soil erosion. One method of creating a furrow in the soil is with the use of a coulter disk which is a tool that penetrates the soil with a minimal amount of soil disturbance. The coulter can be used to insert seed, fertilizer and fungicide or any one of the forgoing into the soil.
One of the consequences of reduced tillage or soil disturbance is increased soil moisture because of reduced evaporation of the soil moisture. One of the problems that is encountered when disk coulters are used to penetrate wet soil is debris adhering to the sides of the disk.
A spring-loaded scraper can be used to scrape this debris from the disk. Failure to keep the disk clean increases the size of the furrow and the amount of soil disturbance. The debris also reduces the disk's ability to penetrate the soil.
The scraper also functions as a protection system for delivery tubes that carry seed, fungicide, fertilizer, etc.
Since soil types and moisture conditions vary greatly from area to area and change with the weather, the amount of scraper pressure required to keep the disk clean of debris varies.
During a seeding operation in wet clay soil, the scraper pressure required to peel the clay-laden debris off of the disk is significant. However, in the wet clay soil, there is a great deal of frictional force available between the disk and the soil to keep the disk turning.
If the farmer then moves into dry, sandy soil with the same scraper pressure setting as used in wet clay, the available frictional driving force between the disk and soil, may not be adequate to overcome the resistance between the scraper and the disk. The spring force on the scraper has to be reduced to be below that which is available between the soil and the disk or the disk will simply not rotate.
Experience has shown that if there is less frictional force available between the soil and the disk coulter, less scraper pressure is required to remove the debris from the side of the disk.
Therefore, a need exists to have an adjustment to adjust the amount of pressure of the scraper against the coulter disk.
SiJN~IARY OF INVENTION
Is an object of the present invention to provide a scraper which has the ability to adjust pressure in relation to coulter disk.
The present invention provides a pivoting scraper and a pivoting torque arm. A torsion spring is attached to the torque arm to generate the scraping pressure on the disk. The present invention makes the scraper quickly adjustable for the variable conditions. A slotted receiver is attached to the ~ 72061-104 strut and is appropriately positioned so that it securely holds the end of the torsion spring in its desired position. The receiver is a slotted bracket with slots which are equal to the diameter of the spring wire. When a farmer wants to change the force of pressure that the scraper places on the coulter disk, the farmer relocates the moveable end of the torsion spring into a different slot in the receiver as required. A hollow tubular handle that has an inner diameter slightly larger than that of the spring wire is generally used to move the moveable end of the spring to another slot.
This invention seeks to provide a disk coulter assembly including:
- a mounting bracket which is attached to a tool bar frame member;
- a disk coulter attached to a mounting hub;
- said mounting hub rotatably attached to a strut;
- said strut being pivotally attached to said mounting bracket;
- resilient means;
- a scraper pivotally mounted onto a torque;

- and a receiving element with at least two slots, said element being attached to said strut, and capable of receiving and securing said moveable end of said torsion spring, such that when desired, and operator can quickly and easily increase or decrease the force that said scraper places on said disk coulter by changing the location of the moveable end of said torsion spring in the receiving element.
This invention also seeks to provide a coulter assembly, for use with an agricultural tool bar, adapted to be pulled behind a power source; said assembly including a scraper adapted to remove debris and soil from a side of a coulter disk; said scraper being attached to a torque transmitting arm;
said arm being secured by a torque transmitting arm holder, and being connected at its upper end to a torsion spring; said torsion spring being adapted to urge said scraper against a disk; wherein the improvement is that a lower end of said spring is adapted to fit within a torsion spring receiver at various locations, thereby varying the pressure exerted by said scraper against said disk.
In order to make the scraper quickly adjustable for the variable conditions; a slotted receiver has been attached to the strut and appropriately positioned to securely hold the end of the spring in this desired position. The receiver is a slotted bracket where the slots are matched to the diameter of the spring wire.
When a farmer wants to change the force of pressure that the scraper places on the coulter disk, the farmer relocates the moveable end of the torsion spring into a different position in the receiver or slotted bracket as required. A hollow tubular handle that has an inner diameter slightly larger than the diameter of the spring wire is generally used to make the changing of the moveable end of the spring easier.

DETAILED DESCRIPTION OF THE INVENTION
Figure 1 shows the prior art type of coulter assembly without the adjustment for the scraper pressure. The coulter assembly is shown generally as 1. At the top of the coulter assembly is the mounting bracket 2. The mounting bracket has a plurality of holes, such that the coulter assembly can be raised or lowered for attachment to a typical agricultural draw bar (not shown). Mounting bracket 2 is attached to tubular frame 3. An extension spring 4 keeps pressure on the coulter disk to maintain it within the soil, in operation. In the particular embodiment shown in figure 1, there is an eccentric element 7 with a lever 8 which is positioned above tab 6 and above eyebolt 5. The latter attaches to the extension spring 4. In this particular prior art coulter assembly, the coulter can be lowered or lifted by use of the eccentric element. At the bottom of extension spring 4, is a scraper tine 9 in which is fitted a scraper tine 10. The scraper tine operates to clean debris from the opposite side of the coulter shown in figure 1.
As typical in all coulter assemblies, there is a coulter disk 11, which generally consists of a flat disk with sharpened circumference. This is used to penetrate the earth generally at an angle and create a furrow. A larger scraper 12, which is torsioned with pressure thereon, is kept in contact with coulter disk 11 by means of scraper torsion spring 15. A scraper shaft or torque transmission shaft 13, is attached to the scraper 12. The scraper spring 15 encompasses the upper portion of the shaft 13. The scraper also serves to protect the granular products depositing tube 14.
In figure 2, which is a side view of the present invention, one sees the scraper 12 torsionally mounted on to the side of coulter disk 11. The surface of the ground 16 is shown. Generally in operation, the coulter disk 11 would penetrate 1 or 2 inches into the ground, depending on the seed being sewn. Coulter disk 11 is secured to a mounting hub 17.
As shown in figure 3, there are bolt holes 18 which attach the mounting hub to the coulter disk. The mounting hub rotates about a spindle 19 which is secured at one end by a seal 20. The spindle 19 is secured to the bottom of strut 21.
As shown in figure 2, strut 21 is pivotally secured to coulter mounting bar 22 which in turn is secured to a horizontal frame member 24 of a tool bar by means of tool bar connecting bracket 26. Bolts 35 secure tool bar connecting bracket 26 to tool bar frame member 24.
As shown more clearly in figure 3, the scraper 12 is attached to right angled scraper shaft or torque transmitting arm 27. The scraper shaft 27 is attached to the scraper by means of a retaining pin 28. A scraper torsion spring 29 which has an upper loop 33 is bolted to scraper shaft 27 at its upper end by means of scraper spring bolt 30.
In the present invention, the lower end of the scraper torsion spring 29 is adapted to fit within the slots of scraper torsion spring bracket or receiving bracket 31.
As shown if figure 5, the lower end of scraper torsion spring 29 is labelled as 32. In figure 5, it is shown in one of the slots of the scraper torsion spring bracket.

Turning back to figure 3, one sees fertilizer connector tube 36. In figure 2, extension spring 37, as well as torque transmitting arm holder 38 can be viewed.
In operation, in order to increase or decrease the pressure of scraper 12 against coulter disk 11, the lower end 32 of scraper torsion spring 29 is moved into different slots of scraper torsion spring receiver bracket 31. The farmer can use a hollow tube tool to lift end 32 out of a slot of the scraper torsion spring receiver bracket and to place the same in another slot with lesser or greater spring pressure.
Figure 5 is a detailed view of figure 4, particularly that of the torsion spring and torsion spring coil receiver;
DETAILED DESCRIPTION OF THE INVENTION
Figure 1 shows the prior art type of coulter assembly without the adjustment for the scraper pressure. The coulter assembly is shown generally as 1. At the top of the coulter assembly is the mounting bracket 2. The mounting bracket has a plurality of holes, such that the coulter assembly can be raised or lowered for attachment to a typical agricultural draw bar (not shown). Mounting bracket 2 is attached to tubular frame 3. An extension spring 4 keeps pressure on the coulter disk to maintain it within the soil, in operation. In the particular embodiment shown in figure 1, there is an eccentric element 7 with a lever 8 which is positioned above tab 6 and above eyebolt 5. The latter attaches to the extension spring 4. In this particular prior art coulter assembly, the coulter can be lowered or lifted by use of the eccentric element. At the bottom of extension spring 4, is a scraper tine 9 in which is fitted a scraper tine 10. The scraper tine operates to clean debris from the opposite side of the coulter shown in figure 1.
As typical in all coulter assemblies, there is a coulter disk 11, which generally consists of a flat disk with sharpened circumference. This is used to penetrate the earth generally at an angle and create a furrow. A larger scraper 12, which is torsioned with pressure thereon, is kept in contact with coulter disk 11 by means of scraper torsion spring 15. A scraper shaft or torque transmission shaft 13, is attached to the scraper 12. The scraper spring 15 encompasses the upper portion of the shaft 13. The scraper also serves to protect the granular products depositing tube 14.
In figure 2, which is a side view of the present invention, one sees the scraper 12 torsionally mounted on to the side of coulter disk 11. The surface of the ground 16 is shown. Generally in operation, the coulter disk 11 would penetrate 1 or 2 inches into the ground, depending on the seed being sewn. Coulter disk 11 is secured to a mounting hub 17.
As shown in figure 3, there are bolt holes 18 which attach the mounting hub to the coulter disk. The mounting hub rotates about a spindle 19 which is secured at one end by a seal 20. The spindle 19 is secured to the bottom of strut 21.

As shown more clearly in figure 3, the scraper 12 is attached to right angled scraper shaft or torque transmitting arm 27. The scraper shaft 27 is attached to the scraper by means of a retaining pin 28. A scraper torsion spring 29 which has an upper loop 33 is bolted to scraper shaft 27 at its upper end by means of scraper spring bolt 30.
In the present invention, the lower end of the scraper torsion spring 29 is adapted to fit within the slots of scraper torsion spring bracket or receiving bracket 31.
As shown if figure 5, the lower end of scraper torsion spring 29 is labelled as 32. In figure 5, it is shown in one of the slots of the scraper torsion spring bracket.
Also shown in figure 5 and nut 34 secures scraper spring bolt 30 to both the upper portion 33 of spring 29 to scraper shaft 27.
Turning back to figure 3, one sees fertilizer connector tube 36. In figure 2, extension spring 37, as well as torque transmitting arm holder 38 can be viewed.
In operation, in order to increase or decrease the pressure of scraper 12 against coulter disk 11, the lower end 32 of scraper torsion spring 29 is moved into different slots of scraper torsion spring receiver bracket 31. The farmer can use a hollow tube tool to lift end 32 out of a slot of the scraper torsion spring receiver bracket and to place the same in another slot with lesser or greater spring pressure.
