Description
Device for circulating grain products
The invention relates to a device according to the upper part of claim 1. Such devices are used in the grain industry in particular for drying and/or storage of grain products.
Freshly harvested grain product has a moisture content, which does not allow for a harmless storage. In moist grain product progressively growing heat nests are created, which destroy the grain product. In addition vermins settle there, which contribute to the destruction of the grain product.
Prior to the actual storage the freshly harvested grain product therefore has to be dried sufficiently, which as a rule takes place in drying silos. In doing so the freshly harvested grain product is fed continuously or in a cycle from above into the drying silo, while dry and warm air is blown from below into the drying silo. The dry air extracts a particular quantity of moisture from the grain product and escapes as exhaust air from the upper region of the drying silo. For increasing the drying process the grain product is continuously circulated and mixed.
For this it is generally known to apply a circulating device stored and operated in the upper region of the drying silo. This circulating device is provided with several adjacently arranged and driven conveyor worms, which immerse into the stored grain product and circulate it respectively from below to above. Due to the circulating movement of 2s the circulating device and by way of a radial positional change of the individual conveyor worms, the conveyor worms reach all regions of the deposited grain product.
OG Ref: 82626
After a sufficient drying process the grain product is brought into : suitable round storage silos or into flat storage halls, where it furthermore has to be aerated and/or circulated continuously. Thereby the creation of heat nests is to be avoided.
A suitable grain fruit circulation storage arrangement for a round storage silo is, for example, described in the DE-OS 27 21 782. This grain fruit circulating storage arrangement is arranged in the centre of the storage silo, is fixedly joined to the storage silo and consists essentially of a conveyor cylinder and a driven conveyor worm. The stored grain product slides over a conical floor into the region of the conveyor worm and is transported by the conveyor worm through the conveyor cylinder into the upper region of the storage silo and is placed onto the deposited grain product. Thus a circulating conveyor movement is created.
This grain fruit circulating storage arrangement is designed as a fixed constituent part of the storage silo and therefore is only intended for this one individual case. Using it in flat storage halls is completely excluded due to the limited effective space, which severely restricts the application range of this grain fruit circulating storage arrangement.
The grain fruit circulating storage arrangement is, due to the required conveyor cylinder also very expensive in construction and expensive in manufacture.
As a rule the grain product, after drying, is brought into large area storage halls, where it is spread flatly. Here the circulation takes place generally by way of manual rotation, which is physically very strenuous and requires many workers. It is also generally known to apply heavy circulation technology for circulating the grain product, which is not available everywhere and additionally is very expensive. From the
DE 35 00 881 Al a drilling worm for turning and loosening the grain
DrG Ref: 82626 product in storage silos is known, which essentially consists of a hand . drill machine and a conveyor worm fitted to the hand drill machine.
The conveyor worm thereby has a length, which corresponds to the height of the deposited grain product. The tip of the conveyor worm is provided with a sphere for supporting the bore worm relative to the silo floor. This drilling worm generally can be applied both in round storage silos as well as in flat storage halls, whereby, however, the effect in particular in storage halls is relatively low. Considerable body forces have to be applied in order to hold the drilling worm during operation in its operative position and to move it positionally for overcoming the resistance of the conveyor worm turning into the grain product. In doing so these drilling worms thereby can only be operated for a very short time period, which practically rules out the application in flat storage halls.
The invention therefore has as object to develop a device of the type mentioned for circulating grain product, which can be applied without time limit and which requires no manual force for circulation.
This object is solved by the characteristics of claim 1.
Suitable embodiments of the device result from the subsidiary claims 2 to 12.
The new device with its two embodiments eliminate the mentioned disadvantages of the prior art.
Thus the particular advantage of the device lies therein that the device is carried by the grain products. In the case of stationary devices, all connections or supports with a dry or storage silo otherwise required thereby fall away. This renders the stationary device to be independent of the type of the silo and thereby expands its application range. The stationary device, carried by the grain products, thus
OrG Ref: 82626 requires no permanent operator, who has to hold the device and guide . it. This simplifies the handing decisively.
The application range is extended further because the device is designed as a mobile device. It therefore can be applied in grain product heaps with large areas, as for example is the case of flat storage for grain products. The mobile device thereby is driven by the back forces of the conveyed grain product in a filling space. Thus mechanical drive units for forward movements of the device fall away.
It is of particular advantage that the filling space of the mobile device can be easily closed so that the mobile device also can be applied and used in stationary operation. This expands the application range of the device.
The invention is to be explained in more detail by way of two examples of embodiments. 1s For this there is shown in:
Figure 1: a side view of a stationary device with a support body which is open to above,
Figure 2: a plan view according to Figure 1,
Figure 3: a side view of the stationary device with a support body which is open to below,

DrG Ref; 82626
Figure 7: another side view of the mobile device,
Figure 8: a plan view of the mobile device and
Figure 9: a side view of the mobile device with a special conveyor worm. 5 The stationary device for circulating grain products according to
Figures 1 to 5 consists mainly of a conveyor worm 1 and a drive unit 2 for the conveyor worm 1. The conveyor worm 1 and the drive unit 2 are releasably joined by way of a coupling unit 3, so that, depending on the application, a conveyor worm 1 with a selected length can be applied. The conveyor worm 1 preferably has an inner guide channel 4 with radial exit openings 5, which are in communication with an air or liquid supply unit 7 by way of a supply tube 6. The drive unit 2 preferably is electrically operated and is rigidly joined by means of attachment elements 8 to the support body 9. 1s According to Figures 1 and 2 the support body 9 is designed cup shaped and therefore has a bottom plate 10 and a circumferential wall 11. Thereby the bottom plate 10 can be formed to be round, polygonal or streamlined. The open side of the cup shaped support body 9 is located above. The floor plate 9 is aligned at right angles to the axis of the conveyor worm 1 and has a dimension, which is adjusted to the conveyor output of the conveyor worm 1. Thereby the size of the floor plate 10 is selected thus that the carrying forces of the support body 9 hold the device on the surface of the grain product.
Due to the alignment of the open side of the cup shaped support body 9 to above the drive unit 2 is fitted in the support body 9 and is attached to the floor plate 10.
The floor plate 10 furthermore has a restraining plate 12, which is arranged parallel to the axis of the conveyor worm 1 and radially to the
DIG Ref: 82626 axis of the conveyor worm 1. Thereby the restraining plate 12 has an } area surface, which is adjusted to the size of the torque at the conveyor worm 1. The restraining plate 12 preferably is adjustable in height and arrestable in different positions in the floor plate 10 in order to allow an adjustment relation to the application size of the torque at the conveyor worm 1.
Figure 3 shows a similar device, also with cup shaped support body 9, which, however, is directed with its open side to below. Here the restraining plate 12 is adjustable and lockable.
In Figure 4 a device for circulating grain product is presented, which again consists of a conveyor worm 1, a drive unit 2 and a support body 9, whereby the support body 9 is designed as a closed hollow body. Due to the additionally operating upthrust forces of the air enclosed in the interior of the hollow body, the support body 9 can be designed to be smaller in its radial expansion. The restraining plate 12 is rigidly attached to the underside of the hollow shaped support body 9. Preferably the restraining plate 12 is welded to the support body 9.
According to Figure 5 the support body 9 of the device for circulating grain product is of plate shape design, the restraining plate 12 being welded in turn to its underside.
The manner of operation of the stationary embodiment of the device for circulating grain product is relatively simple and thus is easy to be seen from the drawing representations of Figures 1 to 5.
The device is placed with its conveyor worm 1 horizontally on the grain product, whereby the free end of the conveyor worm 1 receives contact with the grain product. Thereafter the drive unit 2 is switched on, so that the conveyor worm 1 digs into the grain product. Thereby
OrG Ref: 82626 the conveyor worm 1 tends to turn into the vertical. The digging in is completed when the support body 9 abuts fully on the grain product.
Now the circulation of the grain product starts in that the grain product, located in the course of the threads of the conveyor worm 1 is pushed in the course of the threads to above and is placed onto the surface of the grain product. Thereby only new grain product located at the lowest course of the threads is taken up because in the higher course of the threads there is no free space for receiving further grain product. Thereby the lowest grain product is transported continuously to the surface, whereas the intermediate layers merely slide down into the lower and exposed hollow spaces. By way of the removal and the upper deposit of the grain product as well as by subsequent sliding down of the non-displaced grain product, a circulation in the deposited grain product takes place, the warmer grain layers are displaced to 1s above and cooler grain layers to below. Because no radial forces act on the device, the device always remains during operation at the same position, and the device also remains in its resting position, because the circumferential force, proceeding from the rotating movement of the conveyor worm, is taken up by the restraining plate 12 immersed into the grain product. Thus only the conveyor worm 1 rotates and the device remains at the applied location.
In a particular manner in this circulating process warm or cold air or liquids can be added from the air or liquid supply unit 7 by way of the supply tube 6, the guide channel 4 and the radial exit openings 5. The grain product can be additionally dried or cooled by way of air supply and by way of a suitable liquid the insects, which are present in the grain product, can be combated or the durability of, for example, food grain can be improved.
The mobile device for circulating grain product according to Figures 6 to 9 is in particular suitable for flat storage and consists of a support
OrG Ref: 82626 plate 13 on the floor side and the conveyor worm 1' already known } from the first embodiment. This conveyor worm 1' extends centrally through the floor side support plate 13 and thereby is aligned vertically or at such an inclination to the support plate 13, that the support plate 13 aligns in the front region by way of the conveyor worm 1, which tends into the vertical. The inclination can be adjustable.
The floor side support plate 13 has a circular surface with an open trapezium shaped flat segment. A filling space 14 is formed above the open flat segment of the floor side support plate 1. This has a prismatic form corresponding to the open trapezium shaped flat segment of the floor side support plate 13. The filling space 14 is limited by a face wall 15, two side walls 16, 16' and a lid side support plate 17. Both the face wall 15 as well as the side walls 16, 16' thereby are directed vertically to the floor side support plate 13 as well as the lid side support plate 17 parallel to the floor side support plate 13. The filling space 14 forms an ejection region 18 open in horizontal direction opposite to the face wall 15, covered by the left side support plate 17 and the side walls 16, 16'. Thereby the side wall 16, 16' on the side, which faces away from the face wall 15 and faces towards the ejection region 18, is designed to be pivotable about a vertical rotational axis. Thereby the side walls 16, 16' are sub- divided into a fixed and a pivotable region 19, 19'. In a position orientated to each other the pivotable regions 19, 19' of the side walls 16, 16' provide a minimum ejection region 18 and in a position orientated away from each other the pivotable regions 19, 19' provide a maximum ejection region 18. Thereby one or both pivotable regions 19, 19' can be designed such that they close the filling space 14. Thereby an ejection of grain product is avoided and driving the device during circulation is stopped. An additional support 20, 20 is attached horizontally and directly above the floor side support plate
OrG Ref: 82626 at the pivotable regions 19, 19' of the side walls 16, 16'. These ) respectively have such a size and form that they close the filling
Space 14 to below, so that the pivotable regions 19, 19' of the side walls 16, 16' can be pivoted against each other and reduce or close the filling spaces 14 and the ejection region 18. Both the open flat segment of the floor side support plate 13 as well as the lid side support plate 17 have a size corresponding to the maximum filling volume.
The person skilled in the art is free to design the floor side support plate 13 and the lid side support plate 17 according to the examples of the support body 9 of the stationary device and to integrate therein the filling space required for the drive. On one side the floor side support plate 13 additionally has a raised guide plate 21. Thereby the guide plate 21 is aligned parallel to the working direction of the device. The guide plate 21 is designed such in its size and in its alignment that it can support itself against a grain product wall, which already has been thrown. The size, the form and the attack angle of the guide plate 21 are calculated correspondingly. The person skilled in the art thereby is free to provide one or more additional guide plates 21.
The floor side support plate 13 passes through two height adjustable restraining plates 22, 22'. These are respectively fitted on the side outside of the filling space 14 and have a size and shape adapted to restrain the rotation of the device. The height adjustment of the restraining plates 22, 22' can take place manually or automatically independent of each other in accordance with particular parameters.
Inside the filling space 14, a rear control arrangement 23 dipping into the grain product is applied on the lid side support plate 17, dividing the ejection region 18 centrally, which is pivotable about a vertical rotational axis. The size of the effective area of the rear control arrangement 23 is suitably adjusted in accordance with the control of
DrG Ref: 82626 the device. In the same line with the rear control arrangement 22, and opposite thereto, below the floor side support plate 13, a front control arrangement 24, also dipping into the grain product is applied, which also is pivotable about a vertical rotational axis. The size of the effective area of the front control arrangement 24 corresponds substantially to that of the rear control arrangement 23. Both the front control arrangement 24 as well as also the rear control arrangement 23 are applied for directional control and can be adjusted manually, or also motorized automatically independently of each other within particular parameters. Both the application of the restraining plates 22, 22’, the application of the rear control arrangement 23 as well as the front control arrangement 24, are optimal.
The feed worm 1' is joined rotationally fixed to the drive unit 2’, whereby the drive unit 2' is attached by a reception 25 to the lid side support plate 17. The drive unit 2' can be designed to be both drivable by means of electrical energy or by a combustion machine. On the output side the revolutions amount to about 250 to 750 per minute.
The feed worm 1' is commercially available and has a worm diameter of about 50 to 100 mm. Both the diameter and the inclination of the feed worm 1' as well as the revolutions of the feed worm 1' can be adjusted according to the quantity of the grain product to be transported. The length of the feed worm 1' is also variable and amounts to about between 1 000 and 4 000 mm, whereby its lower end projects into a stack of grain product.
Following on the stationary device according to Figures 1 to 5 the feed worm 1' can be designed as a hollow shaft, which is in communication with the air or liquid feed unit 7.
DIG Ref: 82626
According to Figure 6 the feed worm 1' can have an excentrically : attached weight in the region of the filling space 14, so that with the revolutions of the feed worm 1' this produces additional translatory impulses. Thereby a suitable off-balance 28 can be attached such on the feed worm 1' that the translatory impulses act vertically both onto the face wall 15 as well as onto the ejection region 18. In Figure 9 a conveyor worm 1' is shown, which has a continuously increasing inclination towards the drive side. Therewith different transportation spaces are formed between the teeth flanks, which increase in the direction to the drive unit 2'. As a result thereof the grain product is received not only from the lower regions but also from all level layers of the grain product, surrounding the conveyor worm 1'. The resistance of the grain product, acting on the side onto the conveyor worm 1°, is reduced due to the withdrawal of the grain product over 1s the total length of the conveyor worm 1'. This relieves the transportation movement to the conveyor worm 1' through the grain product. The device preferably is provided in the region of the lid side support plate 17 with side, front and rear coupling units 26, which allow a coupling of several mobile devices by means of suitable spaced apart switches. Therewith a formation of several devices can be combined, which include a larger area of the grain product. Such a formation can consist, for example, of two or more rows of adjacently arranged devices, which on top of that orientate with gaps to each other. Thereby a directional change of the formation can be controlled such that the output of the conveyor worm 1' and therewith the drive speed of one or several outer devices is switched off or reduced so that the switched off or reduced devices become the rotational axis for the overall formation of the devices.
The mobile device furthermore is provided in its rear region with a temperature sensor 27, which measures the temperatures of the
DrG Ref: 82626 ejected grain product and, depending thereon, by way of suitable i control elements determines the drive speed of the device. If the transported grain product shows a higher temperature, then the drive speed is reduced, if the temperature of the transported grain product is lower, then the drive speed is increased. Thereby heat nests can be processed more effectively.
Hereafter the manner of operation of the mobile device in a discontinuous operation in flat storage filled with grain product by attacking a heat nest is to be described. For this purpose the device is placed on the surface of the grain product at the position detected before, at which the heat nest can be located in 1 to 2 metre depth below the surface. Thereby it is useful if the device itself and the conveyor worm 1' are separately transported due to their length.
Thereafter the upper end of the conveyor worm 1' is joined non- rotatably to the take-off side of the drive unit 2' and is placed flatly onto the grain product. Then the drive unit 2' is switched on, whereby the conveyor worm 1' digs independently into the grain product and thereby lowers itself from the horizontal into the vertical position. The conveyor worm 1' transports, corresponding to the revolutions, the diameter and the inclination, grain product into the filling space 14.
After reaching the maximum filling volume in the filling space 14 a suitable filling pressure is created, which, supported at the face wall 15 and the side wall 16, 16', ejects in the direction of the ejection region 18, so that by further transportation the grain product is pushed out of the ejection space 18. The out flow of the grain product from the filling space 14 into the direction of the ejection space 18 produces a counter directed force, which acts onto the face wall of the filling space 14 and which displaces the overall device in a working direction.
Thereby the device, located on the grain product, moves in the working direction, whereby simultaneously the grain product, transported from
OrG Ref: 82626 the region of the heat nest, is pushed out of the filling space 14 and is placed into a grain product wall. Depending on the length of the transportation worm 1' this guides and also the drive unit 2 itself impulse type vibrations into the device, which can assist their movement in the working direction. In addition to the control arrangements 23 and 24, the device can be influenced easily regarding its working direction by an operator by pushing or turning into the one or other direction.
The mobile device can also be applied for mixing grain product during the drying process in a continuous operation in a flat storage filled with a grain product. Thereby the device is aligned by an operator in a first runthrough such that the ejected grain product produces a straight wall directed in the centre of the storage surface. Subsequently the device is aligned such that it comes by way of its guide plate 21 to rest against the thrown wall. In the following circulations the device supports itself under utilisation of the rotational moment in the direction of the guide plate 21 to the last produced grain product wall and is guided thus along the thrown wall. At the end of each stretch the device is returned by an operator into the opposite direction. Thus the overall surface of the storage wall is continuously processed.
The continuous operation of the mobile device can also be achieved automatically. For this purpose the device is provided with suitable emitters, sensors and adjustment drives and is joined to a particular data processing machine. The device emits in suitable time intervals its actual spatial x, y and, if necessary, z coordinates to the data processing machine, which processes the coordinates in a useful program. Then the data processing machine emits parameters to the device, by means of which, for example, the restraining plates 22, 22, the rear control arrangement 23 and/or the front control arrangement 24 are adjusted. The automatic operation of the device
OrG Ref: 82626 in accordance with the invention can be optimised such that by suitably installed sensors a heat nest within the grain stack is detected, which sends the x, y and z coordinates of the heat nest to the data processing machine, thereby this guides the device intentionally through the flat storage to the heat nest. The sensors for determining heat nests also can be temperature measuring, density measuring, oxygen content measuring or carbon dioxide measuring sensors.
