The present invention relates to a cultivating implement with automatic distance regulation relative to the ground.
Description
DK 2022 00910 A1 1
Cultivating implement with automatic distance regulation relative to the ground
The present invention relates to the field of mechanical weed control of crops.
Normally, seed weed is controlled mechanically by disturbing the seed weed by raking and covering the seed weed with soil. Weed that has already formed roots are removed by raking with tines equipped with cutting tools.
To cover the seed weed, the soil is normally tilled thoroughly without damaging the cultivated crop and spring tines are often used on soil cultivating implements, such as harrows, row cleaners, and cultivators, or the like. A spring tine is normally provided with a curved spring section, where the upper end is designed for the fastening to the implement and the lower end or shank is configured for receiving a tine point, such as a harrow tip, ploughshare, cultivator sweep, cutting tools, or similar.
The tine point on the spring tine enters the soil to loosen the soil and to break down clods into smaller fragments. If a tine point encounters a solid obstacle in the ground, the spring section allows the tine to be elastically deformed, thereby allowing the tine point to move around the obstacle and avoid the application of shock loads to the cultivator.
Mechanical weed control of crops is for example known from EP 3656195 relating to a spring tine harrow. According to EP3656195, each tine section is tiltably attached to a carrying frame, and the spring tine harrow comprises a sensor unit configured to determine the extent of tilt of the tine section relative to the first carrying frame. The tilting of the tine section determines the working depth.
Alternatively, a cultivating implement comprising tine shank units extending into the soil and being dragged across the soil surface during operation may comprise a support wheel determining the working depth for the tine shanks. The working depth for the tine shanks is traditionally adjusted manually before using the cultivating implement.
Object of the Invention
The objective of the present invention is to provide a cultivating implement reducing the risk of damaging the crops and at the same time optimising the tilling of the soil by optimising the working depth of the tine shank units.
DK 2022 00910 A1 2
A first aspect of the present invention relates to a cultivating implement comprising a tine shank unit, a bridge, and a support wheel; wherein the tine shank unit is secured to the bridge, wherein the support wheel is secured to the bridge by extendable fastening means in such a way that the distance between the support wheel and the bridge may be varied; wherein the cultivating implement comprises controlling means configured for controlling, preferably continuously, the distance between the support wheel and the bridge during operation, i.e., in real time.
This configuration gives the advantage that the working depth of the cultivating implement's tine shank unit(s) may be controlled in real time depending on the type of soil, which the cultivating implement passes over.
The term “cultivating implement” as used in herein is a “soil cultivating implement” including soil cultivators, such as harrows, row cleaners, and cultivators, comprising one or more tine shank units. Preferably, the cultivating implement is a row cleaner.
In one or more embodiments, the controlling means receives input from a sensor attached to the cultivating implement, e.g., the sensor is attached to the bridge of the cultivating implement.
In one or more embodiments, controlling means receives input from a sensor that measures the distance between the bridge and the ground surface by emitting waves and converting reflected waves into an electrical signal defining the distance, e.g., the sensor may be an ultrasound sensor emitting ultrasound waves or an optical sensor emitting light.
In one or more embodiments, the extendable fastening means comprises guiding means configured to embed an extending part of the support wheel and lock the position of the support wheel relative to the bridge. A preferred example of an extendable fastening means is one that comprises a hydraulic, pneumatic, or electric cylinder/actuator.
In one or more embodiments, the one or more tine shank units comprise(s) a tine shank comprising a first end and a second end, the tine shank being sickle shaped, wherein the first end of said tine shank is substantially straight, and the second end of said tine shank is substantially curved.

DK 2022 00910 A1 3
In one or more embodiments, the bridge comprises means for flexibly fastening the bridge to a moving unit, such as a tractor, or a mobile robot.
A second aspect relates to a method for operating a cultivating implement according to the present invention, wherein - a set point is set for a desired distance between the bridge and ground surface, and then - a sensor measures the distance between the bridge and the ground surface at defined intervals, such as once per 0.01 seconds, or once per 0.05 seconds, or once per 0.1 seconds, - the measurements are transmitted to a controlling means, either by wired or by wireless means, - the controlling means compare the measured value with the setpoint and determines whether to take action or not, - if action is to be taken, a signal is sent to the extendable fastening means of the cultivating implement and the distance is either increased or reduced according to the instructions, - optionally an average value for a time period such as for 1 second or for 150 ms is calculated to estimate the measured distance between the bridge 2 and the ground surface.
As used in the specification and the appended claims, the singular forms "a", "an", and "the" include plural referents unless the context clearly dictates otherwise. Ranges may be expressed herein as from "about" or "approximately" one particular value and/or to "about" or "approximately" another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value.
Similarly, when values are expressed as approximations, by use of the antecedent "about", it will be understood that the particular value forms another embodiment.
It should be noted that embodiments and features described in the context of one of the aspects of the present invention also apply to the other aspects of the invention. Especially, when the expression "in general” is applied according to a feature, it means that the feature may be used with all embodiments of the invention.
Figure 1 shows a side view of a cultivating implement according to the present invention in a first state where the tine shank units are sunk into the soil.
DK 2022 00910 A1 4
Figure 2 shows a side view of a cultivating implement according to the present invention in a second state where the tine shank units are raised above the soil.
Figure 3 shows an embodiment of a tine shank unit which may be used with the invention.
The invention relates to a cultivating implement comprising a tine shank unit 1. Normally, a cultivating implement comprises a plurality of tine shank units 1. The tine shank unit 1 or each tine shank unit 1 is secured to a bridge 2. The bridge 2 is during operation flexible attached to a moving unit or part of a moving unit 3, such as a tractor or a mobile robot.
According to the illustrating embodiment of figs. 1 and 2, the flexible attachment to the moving unit 3 comprises a lower arm 5, and an upper arm 6. Both the upper and the lower arms 5, 6 are pivotably mounted to the moving unit 3, and to the bridge 2, thereby allowing the cultivating implement to move up and down relative to the moving unit 3. A dampening and/or lifting unit 10, which may comprise a hydraulic or electric cylinder/actuator dampens the movement of the cultivating implement relative to the moving unit 3 but may also be used to lift the tine shank unit 1 relative to the moving unit 3, e.g., to be positioned in a retracted position relative to the ground when being transported.
A support wheel 4 is fastened by fastening means to the bridge 2 in such a way that the distance between the support wheel 4 and the bridge 2 may be varied. A cultivating implement according to the invention may comprise a plurality of bridges 2 secured to each other and fastened to the same moving unit 3 during operation. Each bridge 2 may comprise a plurality of tine shank units 1, and a support wheel 4. A bridge 2 comprising one or more tine shanks units 1 and supported by a single support wheel 4 may be referred to as “a section”.
The fastening means securing the support wheel 4 to the bridge 2 are extendable and may comprise guiding means 7 being part of the bridge 2 or being secured immovably to the bridge 2. The guiding means 7 are configured to embed an extending part 8 of the support wheel 4. Corresponding means of the guiding means 7 and the extending part 8 may lock the position of the support wheel 4 relative to the bridge 2. The positions at which the support wheel 4 is locked relative to the bridge may either be at intervals with a pre-defined distance, or the support wheel 4 may be locked at any distance relative to the bridge 2.
Whether the positions at which the support wheel 4 may be locked are distributed at intervals or continuously will depend on the locking mechanism.
The fastening means may be a hydraulic, electric, or pneumatic cylinder/actuator, or similar extendable device.
DK 2022 00910 A1
Controlling means control the distance between the support wheel 4 and the bridge 2 during operation by determining the extension of the extendable fastening means. The controlling means receives input from either an operator or from a sensor, i.e., the distance between the support wheel 4 and the bridge may be controlled either manually and/or automatically 5 during operation.
The controlling means may be a PLC (Programmable Logic Controller) or a similar programmable device.
The advantage of a cultivating implement according to the invention is that the working depth of the tine shank units 1 of the cultivating implement may be controlled in real time depending on the type of soil, which the cultivating implement passes over. According to the invention, the distance between the bridge 2, which determines the position of the upper end of the tine shank unit, may be varied up to e.g., 10-20 cm. If the soil is soft or sandy the tine shank units 1 may sink down into the soil and may thereby damage the roots of the crops instead of just removing weeds between the crops. If soft soil or small distance between bridge 2 and ground surface is registered, then the controlling means transmit an input to the extendable fastening means between the bridge 2 and the support wheel 4 to increase the distance and thereby reduce the working depth.
The set point for the controlling means is set by the operator and is primarily defined by the optimized working depth for the specific crop in question.
The controlling means receives input from a sensor 9, which sensor 9 is normally attached to the cultivating implement. Alternatively, the controlling means could receive input from a map defining the different type of soils in the field to be worked on and the input to the controller would then be a location, or the controlling means could receive input from a drone or the like measuring one or more variables relating to the soil which variables may define the expected working depth of the tine shank units of the cultivating implement.
The controlling means may receive input from a sensor 9 that measures the distance between the bridge 2 of the cultivating implement and the ground surface by emitting waves and converting reflected waves into an electrical signal defining the distance. The sensor 9 may be an ultrasound sensor emitting ultrasound waves or an optical sensor emitting light.
The extendable fastening means used for varying the distance between the bridge 2 and the support wheel 4 may comprise corresponding parts allowing for positioning the support wheel 4 relative to the bridge 2. The bridge 2 may comprise guiding means 7 configured to embed an extending part 8 of the support wheel (4) and lock the position of the support wheel 4 relative to the bridge 2. An example of such extendable fastening means is a
DK 2022 00910 A1 6 hydraulic cylinder/actuator, which at one end is attached to the bridge 2 and at another end is attached to the support wheel 4.
Fig. 1 and fig. 2 illustrates the same embodiment of a cultivating implement in different states. The line “a” indicates the ground surface on which the support wheel 4 rests, while the line “b” indicates the level at which the tine shank units 1 pass through the soil. In fig. 1, the distance between the bridge 2 and the support wheel 4 is at a minimum, the extending part 8 of the support wheel 4 is fully retracted into the guiding means 7.
In fig. 2 the extendable fastening means has been extended to the fullest and the line “b” is positioned above the line “a”, which indicates that either the tine shank units 1 are positioned above ground surface i.e., lifted free of the soil, or the soil is so soft that even the support wheel 4 is pushed below the ground surface.
Method
The invention also relates to a method for operating a cultivating implement as defined above. According to this method, the below steps are continuously repeated, or repeated for a period defined by an operator:
Before operation, a set point is set for a desired distance between the bridge 2 and the ground surface. The set point may e.g., depend on the actual cultivating implement, expected softness of the soil, the type of crops to be cultivated and the type of tine shank units 1 used by the cultivating implement. 1. A sensor 9, e.g., a sensor fastened to one bridge 2 of a plurality of bridges, measures the distance between the bridge 2 and the ground surface e.g., once per 0.01 seconds. The measurements are transmitted to a controlling means either by wired means or by wireless means. The controlling means may be a PLC (Programmable Logic Controller). 2. An average value for e.g., 1 second or for 150 ms (milliseconds) is calculated for the measured distance between the bridge 2 and the ground surface. It is appropriate to calculate an average of the measured values, as the cultivating implement may jump and shake when moved across a field due to stones, roots, and varying structures in the soil. 3. Optionally, the operational status of the cultivating implement may be given the following values depending on the measured average:
Range of status
More than 20 mm above setpoint
DK 2022 00910 A1 7 ja [WenEsmobom 4. If the controller registers a deviation from the setpoint, which is outside desired range and significant enough to correct, then the controlling means will transmit a signal to the extendable fastening means and change the distance between the bridge 2 and the support wheel 4, thereby also changing the distance between the bridge 2 and the ground surface.
That the deviation is significant enough to correct may e.g., be defined by the above table where values of 2, 1, -1, -2 may be considered significant enough to correct.
Tine shank units
The cultivating implement may use all types of tine shank units 1. The tine shank units shown in figs. 1 and 2 are particularly useful for row cleaners. Each tine shank unit 200 comprises a tine shank 210, a housing 220, a coil spring 230, a spring resistance regulation unit 240, and a working depth regulator mechanism 250.
The tine shank 210 is tiltably mounted to the housing 220 by a pin joint. The first end 212 of the tine shank 210 is mounted to an end 234 of the spring 230, and the other end 232 of the spring 230 is indirectly mounted to the housing 220 via a spring resistance regulation unit 240, here embodied as a treaded bolt operably connected to the spring 230, and a treaded nut operably connected to the bolt for adjustment thereof (Easier seen in Figure 2). In this way, the spring is extended as the nut is turned in one way and relaxed as the nut is turned the opposite way.
The housing 220 comprises a working depth regulator mechanism 250 adapted for regulating the working depth of the tine shank 210 by regulating the tilt angle of the tine shank 210. In this specific embodiment, the working depth regulator mechanism 250 comprises three pin holes formed the upper part of the housing 220, and a single pin hole formed in the lower part of the housing 220. The insertion of a working depth regulator pin (not shown) into one of the pin holes allows a user to regulate the tilt angle of said tine shank 210 as the movement of the tine shank around the pin joint is restricted.
The tine shank unit 200 further comprising a tine point (see Figures 1 and 2) adapted for loosening soil, such as a cultivator sweep. The tine point is adapted for releasably fastening to the second end 214 of the tine shank 210.
