Description

Strip laying machine

Technical Field

The utility model relates to a spreader for picking up and collecting root crops, in particular potatoes, comprising: pick-up equipment for picking up root crops; at least one sieving belt supported at the machine frame for transporting the root crop in the direction of the output position for strand laying; and a preferably driverless ground roller supported on the machine frame below the screen belt for levelling and/or re-reinforcing the ground surface, wherein a stripping device of the spreader is assigned to the ground roller.

Background

Such a spreader is known on the market, for example by the company Grimme Landmaschinenfabrik GmbH & co.kg of the grimo agricultural machinery company of germany. A ground roller is disclosed separately, for example, in DE 19 635 493a 1.

What has proven to be disadvantageous in such a spreader is: in the case of heavy, viscous soil which is partially attached to the ground roller, excessive force effort is required for stripping by means of a rigid stripper. Thereby creating variations in the rotation of the ground rollers that result in degraded rolling motion of the rollers on the ground. This causes soil to accumulate in front of the rollers, which further degrades the process and ultimately the soil map. Likewise, the ground roll may be stationary, so that further harvesting is not possible with the aid of the spreader and the ground roll must first be cleaned.

Disclosure of Invention

It is therefore an object of the present utility model to solve the above-mentioned problems of a pipelayer.

According to the utility model, this is achieved by: the stripping device is configured as a rotating body which extends along the ground roller and can be driven by means of a drive.

During the co-operation of the running spreader in operation, in particular of a driverless ground roll, i.e. a ground roll which can be used without a drive acting on the end face or on the shaft end of the ground roll, passively via ground resistance, the rotary body acts as a stripping device as a body which rotates about an axis and which is driven in rotation about a rotational axis in operation in a manner extending longitudinally along the ground roll. The rotating body supports cleaning of the floor roller and thus its operation.

The rotary body is preferably composed of a solid material, wherein the rotary body can also be constructed in multiple layers. Instead of a solid material, the rotating body has a partially hollow region.

In particular, the rotating body is configured as a stripping shaft. Such a stripping shaft has an outer side which faces away from the axis of rotation and which has an envelope which, in operation, is at least substantially cylindrical. Such stripping shafts can be produced simply, can be easily supported beside the respective ground roller on the left-hand and right-hand ends thereof, viewed in the direction of travel, and are an easily drivable and produced construction of the stripping apparatus. The stripping shaft can be actively driven by means of a driving device.

Currently, strand placement is a rear strand placement, in which the root crop is placed on the trailing side of the plant and on the trailing end in operation.

The width of the side surface of the rotating body, which can be used in particular for stripping, is between 90% and 110% of the width of the side surface of the ground roller, which can be used for levelling the ground, viewed in the direction of travel or the main direction of travel. In particular, the outer surface of the rotating body is as wide as the outer surface of the ground roller.

Advantageously, in operation of the spreader, the direction of movement of the side of the rotator directed towards the ground roller (side surface) corresponds to the direction of rotation of the side of the ground roller directed towards the rotator (side surface). Irrespective of the contradictory fact that dirt, which may adhere thereby, is sucked into the region between the rotating body and the ground roller, it surprisingly shows that: in particular in the case of differences in peripheral speed, there is still a peeling action which kicks the stripper aside due to the fact that the body just is in the way. In addition, the rolling process of the ground roller on the ground can be supported.

Typically, the stripping device, i.e. the surface of the rotating body, is arranged closely on the surface of the ground roll, wherein the spacing is particularly less than 15mm, more preferably less than 7mm. In the case of such a spacing, the stripping apparatus is particularly effective. Although the rotating body may abut against the side surface, it is advantageous to arrange the rotating body at a distance of 2mm to 4mm from the ground roller in order to compensate for, for example, manufacturing tolerances.

Advantageously, the rotating body is arranged on the side of the ground roller that is rearward with respect to the main travelling direction, and therefore does not come into contact with the soil that may accumulate before the ground roller. Furthermore, the material which may fall down from the screening belt is peeled off particularly advantageously away from the ground roller into the region behind the spreader due to the direction of rotation.

The rotation body can preferably be driven by means of a drive of the sieving belt. To this end, it is advantageous: the drive of the screening belt is constructed on the rear end of the screening belt and is therefore constructed to be able to pull on the load of the screening belt.

The drive is particularly configured on one side of the spreader and can be formed, for example, by a shaft driven by a drive roller of the sieving belt, via a belt or chain drive, for example, to the stripping shaft. Particularly advantageous space saving is achieved when the drive train to the screening belt is arranged on one side of the spreader and the driven part to the rotation body is arranged on the opposite side of the spreader.

In particular, the drive is configured such that in operation the peripheral speed of the rotating body is smaller or greater than the peripheral speed of the ground roller. This is caused in particular by the corresponding gear ratio in the drive train towards the rotating body and by the selection of the outer diameter of the rotating body in relation to the ground roller. For example, on the drive shaft of the sieving belt, a gear or belt drive disk is present, which, in combination with a corresponding gear or belt drive disk on the side of the rotary body, causes an adapted gear ratio of the drive, so that a circumferential speed difference is obtained which promotes the stripping action given the diameter of the rotary body configured as a stripping shaft. It is particularly preferred that the peripheral speed of the rotating body on its outer side is smaller than the peripheral speed of the ground roller, but greater than zero.

Advantageously, the diameter of the rotation body corresponds at most to half the diameter of the ground roller, preferably wherein the rotation body is arranged at the level of the rotation axis of the ground roller as seen in a side view. This relates to the running position of the spreader. Thus, in operation, the rotator has a sufficient distance from the ground and occupies a small amount of space. Alternatively, the arrangement completely above the axis of rotation further enlarges the gap from the ground.

In general, it is also possible to additionally distribute stripping bodies, in particular strips or plates, preferably made of metal or hard plastic, to the stripping shaft, which strip off the material that has accumulated on the surface of the stripping shaft.

Advantageously, the outer surface of the rotating body is configured to be free of patterns, which reduces adhesion of heavy soil.

Furthermore, according to a further embodiment of the utility model, the rotary body can be supported indirectly on the machine frame via the side plates supporting the floor roller, so that a corresponding stripping device can also be provided subsequently.

Detailed Description

The spreading machine 2 according to the utility model has a pick-up device 4 arranged on its front end. In this case, it is currently a row of planing tools 5 which draw potatoes out of the potato ridges and guide them in the direction of a screening belt 8 arranged at the machine frame 6 (fig. 1). Furthermore, the spreader according to the utility model is equipped with further screening strips 9, wherein both screening strips 8 and 9 guide the root crop onto the ground in the direction of the rear output position. In order to level the ground surface 11 affected by the pick-up device 4, a ground roller 10 is also arranged below the screening belt 8 and below the screening belt 9, which is also supported on the machine frame 6. The stripping apparatus 12 is assigned to the floor roller, which has a rotary body 14 (fig. 3) which runs along the floor roller 10 and can be driven by means of a drive which is described in more detail below. The rotating body is arranged behind the ground roller 10 in the main travelling direction F.

The rotary bodies 14 are rotatably supported at the end sides in respective connecting rods 20 which are fixed to side plates 22 of the machine frame 6. The fastening takes place via screw-like fastening means 24 which engage on the one hand through recesses of the side plates 22 and on the other hand through long holes 26, indicated by broken lines, of the connecting rod 20. Due to the elongated holes 26, the rotating body 14 can be more closely guided to the ground roller 10 or further away therefrom.

The rotary body 14 is driven via a drive element 16 of the drive, which is currently constructed in the form of a chain, which drives a gear wheel 30 located on a drive end 28 of the rotary body 14. Currently, the chain is driven via a gear 34 located on the drive shaft 32 of the screening belt 8 or the screening belt 9.

The central longitudinal central axis of the ground roller 10 and the rotary body 14 configured as a stripping shaft runs parallel to and preferably horizontal to the ground (fig. 3). The width of the side or outer surface 15 of the rotating body 14, seen in the main travelling direction F, is between 90% and 110% of the width of the side surface of the ground roll 10 available for levelling the ground. In particular, both side surfaces of the bodies 10 and 14 are the same width.

The floor roller 10 does not have its own drive. The direction of rotation a of the rotation body 14 corresponds now to the direction of rotation of the drive shaft of the screening belt or the screening belts 8 and 9. Accordingly, the rotating body 14, which is arranged on the side of the ground roller 10 at the rear with respect to the main travel direction, can support the ground roller in its rotation direction B (fig. 4) if necessary when placed on the ground roller. This also applies to the case where a possible accumulation on the rotating body 14 or the floor roller causes a gap between the rotating body 14 and the floor roller 10 which otherwise has a width D to close (fig. 4).

The gear ratios of the sprocket wheels 28 and 34 are chosen such that the peripheral speed of the stripping shaft is preferably lower than the peripheral speed of the ground roll 10, so that due to this difference a stripping action occurs with respect to the material adhering to the ground roll.

Advantageously, the outer surface of the rotating body 14 is configured to be free of patterns, so that uniform stripping is obtained via the correspondingly configured outer surface of the ground roller.

Advantageously, a structural separating means, for example a plate, can be provided between the chain on the drive shafts of the screening belts 8 and 9 and the wedge-shaped belt pulley, which separating means prevent possible lubricating material of the chain from being transferred to the wedge-shaped belt or its belt pulley.
