Description

A DEPTH CONTROLLING BELT ARRANGEMENT FOR A SOIL WORKING IMPLEMENT
The present invention relates to a depth controlling arrangement for a soil working implement, arranged to be able to be mounted to a frame and comprising a depth controller, and wherein the depth controlling arrangement comprises an, in operational state, endless belt forming a contact face against a ground. The invention further relates to the use of a belt arranged on a belt frame as depth controlling arrangement for a soil working implement.
The working depth for a plough is traditionally controlled by a combination of a height adjustable depth wheel in the rear end of the plough as well as hydraulic depth control in lift arms, which connects the plough to a tractor that pulls the plough. On soil with a low bearing capacity, it may be useful to use an extra big depth wheel, possibly a wheel assembly having two depth wheels mounted at a distance from each other. On a reversible plough, a wheel arm carrying the depth wheel will alternately be on the left and right side of the depth wheel.
The disadvantage of the depth wheel(s) as described above is that when ploughing an edge portion, which delimits the field which is ploughed, the depth wheel arrangement may hinder the ploughing of the far edges of the field, because the outwardly protruding wheel arrangement may come in conflict with a fence or a hedge which encircles the field. Therefore there is a need for a depth control arrangement which replaces depth wheel and which builds less in the width of the plough, without reducing the load-carrying capacity. There is also a need for a depth control arrangement, which is more robust with regards to puncturing, which is a well-known problem with depth wheels when ploughing in stubble after growing maize.
GB 191501581 A describes a driving belt arrangement for an automotive soil working implement, typically of the kind where a plough is arranged at each end of a central drive unit, and where the implement alternately works the soil with the one or the other plough, as the one plough is right-turning and the other plough is left-turning. The driving belt arrangement comprises a belt arranged on each side of the drive unit, and they are connected to a driving gear comprising a motor. The working depth of the ploughs is regulated by means of a bar connecting the ploughs to a frame which extends horizontally out from the central drive unit, possibly also by means of a support wheel mounted in the rear ends of the ploughs.
WO 9424842 Al describes a hydraulically operated depth wheel arrangement for a trailed plough where two parallel depth wheels are arranged coaxially at a distance from each other on a frame, which can be displaced vertically in order to contribute to depth controlling of the plough during working, and to act as transport wheels during moving of the plough when it is in raised transport position.
US 4592429 A describes a reversible plough with a front-mounted, single axle turning wheel assembly, wherein the turning function is connected to a rear mounted depth wheel in a master/slave-system, as the rear mounted depth wheel is suspended from the plough such that it is revolving around a vertical axis.
The invention has for its object to remedy or reduce at least one of the drawbacks of the prior art, or at least provide a useful alternative to prior art.
The object is achieved through features, which are specified in the description below and in the claims that follow.
A belt arrangement is provided as a rear depth controlling arrangement for a plough, wherein an endless belt preferably made of a flexible material, for example reinforced rubber, has a contact face against the ground with a certain length which is considerably larger than the width of the belt, typically with a width/length ratio in the range of 1 :4 to 1 : 8. Thereby it is achieved that the support surface of the depth controlling arrangement may be adapted to the actual design conditions by means of simply adjusting the contact face of the length of the belt without influencing on the width of the arrangement. At the same time the overall height of the depth controlling arrangement is limited separately from the desired size of the contact face.
The belt arrangement may preferably be adjusted in order to adapt the contact face to the prevailing working conditions by changing the distance between lower support rollers. For a belt with a given length this change is compensated by moving one or more upper support rollers in order to maintain the tension in the belt. Alternatively a belt with a different length may be inserted.
In a first aspect, the invention more specifically concerns a depth controlling arrange- ment for a soil working implement, arranged to be able to be mounted to a frame and comprising a depth controller, and wherein the depth controlling arrangement comprises an, in operational state, endless belt forming a contact face against a ground, wherein a belt frame is rotatable around a rotation axis substantially congruent with the working direction of the implement.
The belt frame may comprise at least three support rollers arranged to direct the belt in a linear movement in the contact of the belt against the ground.
The belt frame may be connected to the frame of the plough by means of a support arm, which is pivotal around a first rotation axis arranged transversally to the working direction of the soil working implement.
The belt frame may be fastened to a support arm by means of a belt frame bearing, which forms a second rotation axis arranged transversally to the working direction of the soil working implement.
Between the belt frame bearing and the belt frame at least one rotation restraining friction element may be arranged.
In a second aspect, the invention more specifically concerns use of a belt arranged on a belt frame as depth controlling arrangement for a soil working implement.
The soil working implement may be a plough.
In the following is described an example of a preferred embodiment illustrated in the accompanying drawings, wherein :
Fig. 1 shows in perspective, a soil working implement provided with a depth controlling arrangement according to the invention; and
Fig. 2 shows in a larger scale a section of a rear portion of the soil working implement with the depth controlling arrangement according to the invention.
In the drawings the reference numeral 1 denotes a soil working implement, here shown as a reversible plough. In the following description, the term "plough" is used for the soil working implement. The plough 1 comprises multiple working organs 11 in the form of plough bodies arranged on a frame 12. In a rear portion 121 of the frame 12 a depth controlling arrangement 2 is placed, arranged to be able to make sure that the plough 1 in its operational state keeps a constant working depth in a ground 3 (see Figure 1).
Referring to Figure 2, the depth controlling arrangement 2 is provided with a belt frame 21 which via a bearing pedestal 211 and a belt frame bearing 212 is attached to a support arm 23 pivotal about a horizontal rotation axis 2121 arranged transversally relative to the working direction of the plough 1. The belt frame 21 is provided with a front support roller 213, a rear turning roller 214 and a front turning roller 215, which form guiding elements for a belt 22 formed from a suitable material, typically reinforced rubber. The belt 22 is on a support surface 221 preferably provided with not shown ribs, knobs or the similar arranged to increase the friction between the belt 22 and the ground 3 and thereby preventing the belt 22 from sliding on the ground 3. One of the rollers 213, 214, 215, preferably the rear turning roller 214, is formed as a tensioning roller as it is displaceably connected to the belt frame 21. A contact face 222 against the ground 3 is formed from a belt portion, which runs between the front support roller 213 and the rear turning roller 214.
In order to stabilize the belt frame 21 in a normal working position with the contact face 222 substantially parallel to the ground when the plough 1 is lifted from the ground 3, the belt bearing frame 212 is provided with at least one friction element 2122 which restrains the pivotal movement of the belt frame 21 around its transversal rotation axis 2121.
The support arm 23 is connected to a frame connection 231 pivotal around a horizontal axis 2311 transversally placed with regards to the working direction of the plough 1. A depth controller 232, here shown as a crank, forms a second connection between a rear portion of the frame connection 231 and the support arm 23. When the depth controlling arrangement 2 is used on a reversible plough, as shown here, said transversally placed rotation axis 2311 is arranged to be pivotal around a rotation axis substantially congruent with the working direction of the plough 1 in order to attend to the need for readjustment of the depth controlling arrangement 2 when the plough 1 is turned. The frame connection 231 is connected to a rear frame portion 121 of the plough 1.
The vertical and horizontal distance between the front support roller 213 and the front turning roller 215 provides a front tilted path of motion 223, which makes sure the belt 22 passes over uneven parts of the ground 3.
