Description

DESCRIPTION

The invention relates to a device as defined in the definition of the first claim. This type of plant is used in cereal farming, namely drying and / or storage of cereals.

The newly harvested grain has a certain amount of moisture which makes fault-free storage impossible. Wet grains cause ever-increasing thermal nests that destroy grains. In addition, there are abundant parasites that contribute to the destruction of the grain.

Thus, before the grain is harvested, it must be sufficiently dried, which usually occurs in dry silos. As a result, the newly harvested grain is continuously or cyclically placed on top from a dry silage, while dry and warm air is blown from the bottom to the dry silage. The dry air extracts a certain amount of moisture from the grain and exits as the performing air from the upper part of the dry silage. In order to speed up the drying process, the grains are inverted and mixed continuously. In addition, there is a widespread knowledge of the need for use of a rotary tipping device that is stored on the top of a dry silo. This tipping device has a number of side-by-side, operable screw conveyors that cling to the stored grain and mix it from the bottom up each time. Rotary swiveling movements and radical positioning of individual screw conveyors reach all locations of stored grain.

After a sufficient drying process, the grain is placed in storage in an appropriate large storage silo or moved to a flat storage shed, which must then be continuously air-ventilated and stirred. This prevents the emergence of thermal jacks.

A corresponding grain rotary storage device for a large storage silo is described, for example, in DE-OS 27 21 782. This grain rotary storage device is positioned in the middle of a storage silo, firmly connected to the storage silo and consisting essentially of a helical cylinder and a driven screw conveyor. The stored grain slides through the conical bottom into the screw conveyor area and is pushed by the screw conveyor through the helical (promotion) cylinder into the upper storage silo area and again placed on the stored grain. This is how the circular helical / stimulating movement occurs.

This grain rotary storage unit is designed as a strong storage silage component and is designed for this single application only. Applications in flat storage hangars are not possible due to the limited area of use, which greatly limits the area of use of this grain storage unit. This grain rotary storage device is very costly due to its screw structure and very expensive to manufacture.

After drying, the grains are usually placed in very large hangars, where they are spread flat. Turning around here is usually done by hand layering, repositioning what is physically demanding and labor intensive. It is also common knowledge that grain rotation uses a heavy inversion technique, which is unfortunately not everywhere and very expensive. DE 35 00 881 A1 discloses a drill auger / screw conveyor for turning and milling grain in storage, which essentially consists of a hand drill and a hand drill tensioned screw conveyor. The screw conveyor, meanwhile, has a position that corresponds to the height of the shaken grain. The auger conveyor has a ball to support the drill auger at the bottom of the silo. This drill screw can be installed in both large silos and flat storage sheds, while the effect is extremely small in storage sheds. Thus, high physical forces are used to overcome the resistance of the grain rotary screw conveyor to keep the drill screw in position during its operation and to move it further to the proper locations. As a result, drilling screws are only used at very short intervals, which in practice prevents them from being used in flat storage.

US-A 4 491 422 discloses a similar device for flushing grain from the lower storage portion to the upper one, which is constructed in the same manner as an additional stop plate, which withstands mass and stimulating forces and prevents the device from immersing in the grain.

US-A 5 980 100 describes a device for treating a liquid, such as mixing and supplying used water. This unit consists of an escalator wheel and a dedicated motor unit. The motor unit and the escalator wheel are interconnected by a clutch / coupling unit. This unit holds the used water in the escalator wheel and, in a special case, supplies air to the water through the line.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a generally suitable device for grain consumption which can operate indefinitely and does not require manual labor.

This problem is solved by the features shown in definition 1. Useful device designs are described in the following definitions 2 to 11.

The new unit, with both forms of construction, eliminates the aforementioned technical disadvantages.

In addition, the special benefit of the device is that the device can be removed from the grain. In this case, all the connections and supports that are needed for a stationary unit are removed in dry or storage silos. The stationary unit becomes independent of the type of silage and this expands its application. A fixed grain ejection / removal device does not require any continuous service personnel to store and operate the equipment. This unambiguously simplifies management.

The field of application is also expanding as the device is designed as a mobile device. Thus, it can also work in large-area cereal pots, such as in flat-grain storage. In addition, the mobile device is driven by backflow forces generated in the filling space / space. As a result, it carries mechanical forces (units) for further movement of the unit. As a particularly positive side, the filling space of the mobile device is relatively easy to close, so the mobile device can also be used during stationary operation. This again expands the scope of application of the device.

The invention may be further elucidated on the basis of the two construction examples described below.

Stationary plant for grain consumption according to fig. 1 to 5 consisting essentially of a helical conveyor 1 and a motor unit 2 for a helical conveyor 1. The helical conveyor 1 and the motor unit 2 are interconnected separations of the clutch device 3 so that the length of the helical conveyor can be selected depending on the starting case. The screw conveyor has an internal deflection channel 4 with a radial outlet 5 which is connected via a supply / supply hose 6 to a fluid and air supply device 7. The motor device 2 is mainly electrically driven and is rigidly connected by a fastening element 8 to a support / cover housing. 9th

According to Fig. The support / cover housing 9 and 1 are constructed in the form of a pot and therefore have a bottom plane 10 and a rotating / enveloping wall 11. Meanwhile, the bottom plane 10 can be round, rectangular or sleek. The open side of the pot-shaped support body 9 is at the top. The bottom plane 10 is formed rectangularly on the propeller axis 1 and its size is aligned with the propelling / performing power / capacity of the propeller 1. The size of the bottom plane 10 is chosen such that the tensile support body 9 holds the force device against the cereal surface. Based on the fact that the pot-shaped support body 9 has an open side at the top in its design, the motor unit 2 is mounted in the support body 9 and secured to the bottom plane 10.

The bottom plane 10 further has a stop plate 12 which is arranged parallel to the axis 1 of the propeller and formed by a radius of the axis 1 of the propeller. Meanwhile, the size of the plane 12 of the stop plate is matched to that of the propeller 1 at torque. The stopping plane 12 is usually of variable height and is locked in various positions in the bottom plane 10 to determine the amount of use associated with the propeller rotation at 1 moment.

Fig. 3 shows the same device with a support body 9 also constructed in the shape of a pot, but which is constructed with the open side facing down. Here too, the stop plate is formed with a sliding and locking mechanism.

Fig. 4 illustrates a cereal tipping device which again comprises a screw 1, a motor unit 2 and a support body 9 while the support body 9 is constructed as a closed hollow object. Due to the additional action of the enclosed air force inside the hollow object, the support body 9 may be enlarged with respect to its radius. The stop plate 12 is rigidly fixed to the hollow support body 9. Most often, the stop plate 12 is welded to the support body 9.

According to Fig. 5. the cereal support housing 9 is formed in a planar configuration and the lower part is again welded to a stop plate

12th

The mode of operation of the stationary construction of the cereal mixing device is relatively simple and can therefore be easily understood from the drawings in Fig. 1 to 5. The auger unit is placed horizontally on the crop, while the free end of the auger 1 must be in contact with the crop. The motor unit 2 is then connected so that the auger 1 digs into the crop. Meanwhile, the propeller 1 is encouraged to roll up vertically, the cessation being completed when the support body 9 is resting on the crop in its entire plane. Grain promotion / spinning now begins when the grain in the grooves in thread 1 is pushed upward along the grooves and left on the grain surface. Meanwhile, only the lower threads constantly pick up new grains, since the higher threads have no more free space to take in new grain. In this way, the bottom grain is constantly transported to the surface, and the intermediate layers slip into the voids that have become on the ship each time. Due to the lower grain removal and topping, as well as the slippage of the discontinuous grain, the grain is placed in a circulation which raises the warmer layers of the grain upwards and cooler downwards. Since the unit is not subjected to any radial force, the unit remains permanently in the same position during operation, and remains in the same position at rest, since the encircling forces from the motions of the rotary screw 1 are received by the submerged motor unit 2. while the unit stays in its place of installation. In a particular way, warm or cold air or liquids from the air or liquid supply device 7 can be introduced during the feeding process through the supply hose 6, the deflection conduit 4 and the radial outlet radial openings 5. insects can be killed or forage storage improved, for example.

Mobile device for grain consumption according to fig. 6 to 9 are particularly adapted for flat storage and consist of a cover plate on both sides 13 and a screw 1 in the first embodiment. This screw extends centrally through the cover plane on both sides 13 and is formed perpendicularly or with a certain inclination towards the cover plate 13, that the cover plate 13 at the front is perpendicular to the propeller 1. The inclination can be determined.

The cover plane on either side of the bottom 13 has a circular surface with an open trapezoidal surface segment. A fill space 14 is formed above the coating plane on either side of the bottom open surface segment. It has a prismatic shape corresponding to the coating surface on either side of the bottom surface 13. The filling space 14 is limited by the front wall 15, the two side walls 16, 16 'and the cover plate on both sides of the lid 17. Meanwhile, both the front wall 15 and the side walls 16, 16' are formed perpendicular to the cover plate on both sides 13 and the cover plate 17 is formed parallel to the cover plate on either side of the bottom 13. The filling space 14 forms, in front of the front wall 15, covered by the cover plane on both sides of the cover 17 and laterally bounding walls 16, 16 '

18. Meanwhile, the sidewalls 16, 16 'are sideways, inclined from the front wall 15 and facing away from the slide region 18 to form a pivot axis. In this way, the side walls 16, 16 'are divided into a stationary and movable part 19, 19'. The movable portions 19, 19 'of the sidewalls 16, 16' form a minimum filling cavity 18 in a mutually oriented position, and the movable portions 19, 19 'of the sidewalls 16, 16' relative to each other form a maximum filling cavity 18. or both moving parts 19, 19 'can be folded to close the filling cavity 14. This prevents the grain ejection path and stops the device from working during rotation. At the side walls 16, 16 ', movable parts 19, 19' are mounted under the horizontal and additional covers 20, 20 'are mounted just above the cover plate on both sides of the bottom. This provides such a size and shape that the filling space 14 closes downwardly, only the movable parts 19, 19 'of the side walls 16, 16' are moved against each other and the filling cavity 14 and the ejection area are reduced and closed. Both the open surface segment on the cover plate on both sides of the bottom 13 and the cover plate on both sides of the cover 17 provide a size defined for the maximum fill volume.

The person skilled in the art may optionally construct a cover plate on either side of the bottom 13 and a cover plate on either side of the cover 17 according to examples of a stationary device support housing and integrate the filling cavity required for the engine / operation there. The cover plate on either side of the bottom 13 also has, on its side, a retractable guide plate 21. Meanwhile, the guide plate 21 is constructed parallel to the working direction of the device. In addition, the baffle plate 21 is of such a size and construction that it can rest on an already thrown grain bed. The size, shape and mounting angle of the guide plate are adjusted accordingly. The practitioner may choose to provide one or more additional guide plates 21.

Two height adjustable stop plates 22, 22 'pass through the cover plate on either side of the bottom 13. These are located on the outside of the filling space 14 on both sides and have a size and shape adapted to prevent rotation of the device. The height adjustment of the stop plates 22, 22 'can be done independently of the crossing either manually or automatically by appropriate parameters, motorized. Inside the filling cavity 14, the filling cavity 18 is divided in half, and a rear grain-shaped control device 23 is mounted on the cover plate on both sides of the lid, which is rotated about a perpendicular axis of rotation. The size of the plane affected by the rear control unit 23 is adapted accordingly to the control of the unit. In the same line with the rear control unit 23, and opposite to it, there is a front as well as grain-like control unit 24 underneath the cover plate on either side of the bottom 13, which is also rotated about a perpendicular axis of rotation. The size of the plane affected by the front control unit 24 corresponds approximately to the rear control unit. Both the front control unit 24 and the rear control unit 23 are mounted for directional control and can be independently adjusted manually or automatically by appropriate parameters, motorized. Both the stop plates 22, 22 ', the rear control unit 23 and the front control unit 24 are optional.

The propeller T is rotationally coupled to the motor unit 2 'and the motor unit 2' is secured to the cover plate on both sides of the cover 17 via a bushing 25. The motor unit 2 'can be driven by both electric power and an internal combustion engine. The rotation speed is 250-750 min ¹ .

The screw T is normal and has a diameter somewhere between 50 and 100 mm. Both the diameter of the propeller T and the pitch of the propeller and the number of rotations of the propeller T are determined by the amount of grain being promoted. The length of the auger T can also be varied and is between 1000 and 4000 mm while its tip reaches the grain pile.

Based on a stationary device according to fig. The propeller 1 to 5 is formed as a hollow line which engages the air and fluid supply unit 7.

According to Fig. The auger 6 has an eccentric weight in the region of the filling cavity 14, resulting in additional linear (repetitive moving) pulses with the rotation of the auger 1. In addition, the corresponding imbalance 28 is fixed to the propeller T such that linear pulses perpendicularly affect both the front wall 15 and the ejection region 18. FIG. Fig. 9 shows a propeller T, which has a gradually increasing step towards the motor side. This results in different promotional cavities between the serrated wings, which increase towards the motor direction 2 '. As a result, the grain is taken not only from the lower regions, but also from all the void layers of the grain stack comprising the propeller T. Removing the grain across the entire length of the auger T reduces the lateral grain resistance of the auger. This facilitates propeller transport movements through the grain. The device is typically provided with a side, front and rear clutch / coupling device 26 in the area of the cover plate on both sides of the cover 17, which engages a plurality of mobile devices through a respective spacer. In this way, the structure can be formed from several devices and thus cover a larger area of grain. Such a structure may consist of two or more rows of adjacent devices which are oriented in relation to each other. In addition, the design change is controlled by disabling or reducing the propulsion activity of the propeller T and thereby reducing the engine / operating speed of one or more of the exterior units so that disengaged or reduced units become the axis of rotation of the overall design of the units.

The mobile unit is further provided with a temperature sensor 27 at its rear which measures the temperature of the grain expelled and then determines the engine speed of the unit through the appropriate control units. If the ejected grain is at a higher temperature, then the engine speed is reduced, if the ejected grain is at a lower temperature, then the operating / engine speed is increased. In this way, the heat sockets can be processed more efficiently.

The following describes the operation of a mobile device during continuous operation in a grain-filled hangar / storage facility to combat heat sockets. To do this, the unit is placed on a cereal surface on a pre-designated location, which is a thermal outlet at a depth of 1-2 meters from the surface. It is also expedient to transport the unit and the screw T separately due to its length. The upper end of the screw T is then screwed firmly with the operating side of the motor unit 2 'and placed flat on the grain. The motor unit 2 'is then actuated, which causes the propeller T to self-dig into the crop and lower from horizontal to vertical. The screw propels the grain into the filling cavity in accordance with the number of rotations, diameter, and increments 14. When the maximum filling volume of the filling cavity 14 is reached, the corresponding filling pressure is exerted to the front wall 15 and sidewalls 16, 16 '. and in the event of subsequent pushing, the grain is pushed out of the ejection part. The ejection of the grain from the filling cavity 14 into the ejection portion 18 causes a backward force which acts on the front wall of the filling cavity 14 and pushes the entire device towards the working direction. As a result, the device moves while lying on the grain in the working direction, while the grain promoted from the heat socket area is pushed out of the filling cavity 14 and left on the emerging grain embankment to be influenced by the propeller T length and the 2 'pulse type vibrations in the device. their movements are driven towards the direction of work. The unit may be further actuated by pushing or rotating one of the service personnel to one or the other direction in the direction of its movement towards the control units 23 and 24.

The mobile unit can be used for continuous operation in a grain filled storage facility for mixing grain during the drying process. Here, the unit in the first passage can be constructed by the service person so that the grain thrown forms a barrage in the middle of the storage. Finally, the device is configured to guide the guide plate 21 for positioning the flush embankment. In further circulations, the device rests on the deflection plate 21, utilizing a torque in the direction of the deflection plate 21, respectively, for the final grain embankment and guided along the discarded embankment. At the end of each section, the machine is moved in the opposite direction to the operator. In this way the entire storage area is continuously processed.

The continued operation of the mobile device is realized automatically. For this purpose, the unit is equipped with appropriate sensors, sensors, control actuators and linked to a tuned data processing machine. The device sends the actual room χ-, y- and sometimes z- coordinates to the data machine at appropriate time intervals and the coordinates are processed by the respective program. The data processing machine again sends the parameters to the device on the basis of which the stop plates 22, 22 ', the rear control unit 23 and / or the front control unit are changed.

24. The automatic operation / control of the device according to the invention is optimized so that the respective installed sensors detect a heat socket inside the grain gap, the x-, y- and z- coordinates of the heat socket are sent to a data processing machine and then the unit is purposefully guided towards the outlet. Sensors for transmitting a heat socket can measure temperature, density, oxygen, or carbon dioxide.
