    The invention relates to a feed conveyor with a movable housing and arranged on a front part of the housing bearing housing, wherein in the bearing housing a screw conveyor with a transversely oriented to the direction of travel of the mobile housing conveying direction is rotatably mounted, which comprises a worm shaft and a screw shaft arranged on the worm shaft comprises, according to the preamble of claim 1.
    Feed conveyors of the type mentioned are used in modern barn technology to bring the loosely provided in the feed gear feed close to the bars again. Devices suitable for this purpose have been described, for example, in DE 3725690 CI and DE 299 13 549 Ul. The livestock is on the other side of the bar but low enough to allow the cattle to feed. However, the feed must be placed sufficiently close to the ingot in the feed passage and loosened and mixed well with the livestock. For this purpose, automatically moving on the stable floor moving feed conveyor are known to complete a preprogrammed route and thereby orient themselves based on arranged in the feed gear marker magnets. The feed conveyor moves along the feed passage close to the ingot and feeds the feed that is scattered in the feed aisle close to the ingot again using the screw conveyor. In the housing of the feed conveyor are the wheel drive for the wheels and / or rollers of the mobile housing, the worm drive for the screw conveyor, sensors for the marking magnets, connected to the sensors control device for the wheel drive and the worm drive and a generally rechargeable running power supply for arranged all the aforementioned components.
    Conventional feed conveyors furthermore have a bearing housing arranged on a front part of the housing, wherein the conveyor worm is rotatably mounted in the bearing housing. The screw conveyor is arranged transversely to the direction of travel of the feed conveyor in the bearing housing, wherein the length of the screw conveyor substantially corresponds to the width of the bearing housing and the screw conveyor runs with its lowermost peripheral region just above the footprint of the mobile housing. If the feed conveyor travels along the billet in the feed passage, the feed is picked up by the feed screw over the width of the bearing housing, offset transversely to the direction of travel in the conveying direction of the feed screw and ejected close to the billet.
    The auger comprises a worm shaft and a worm thread arranged on the worm shaft. The worm shaft is usually tubular and carries the worm thread, the worm shaft and the
    Worm threads are made in a conventional manner from a metallic material. The worm thread is usually designed in the form of a welded to the worm shaft steel strip. This design involves increased risk of injury in practice, if the operator with the foot or the hand gets into the screw thread, or an animal is caught during the feed intake with his head from the screw thread. In addition, the worm thread tends to become increasingly sharper in the course of use at its outermost thread edge by wear of the thread flanks, whereby the risk of injury increases.
    It is thus the object of the invention to provide a feed conveyor which, compared to conventional feed conveyors, has a reduced risk of injury without impairing the conveying capacity, but on the contrary improves the conveying capacity.
    This object is achieved by the features of claim 1. Claim 1 relates to a feed conveyor with a movable housing and a bearing housing arranged on a front part of the housing, wherein in the bearing housing a screw conveyor with a transversely oriented to the direction of travel of the mobile housing conveying direction is rotatably mounted, which comprises a worm shaft and a screw shaft arranged on the worm shaft includes. According to the invention, it is proposed here that the worm thread has a plastic casing which forms a sawtooth-like thread profile.
    The inventive construction of the worm thread has several advantages. First, the risk of injury is reduced, since the plastic structure according to the invention has much less potential to inflict injuries on an operator or an animal than a circumferential steel thread. In addition, with the aid of the plastic construction according to the invention, greater design possibilities with regard to the thread form are made possible, which can thus be more easily optimized for feed conveyance. According to the invention a sawtooth-like thread profile is proposed for this purpose, on the one hand reduces the risk of injury due to its shape, since no radially projecting thread crests occur more, and on the other hand improves the capacity of the screw conveyor. Conventional screw conveyors always overlap the lateral sliding movement of the chuck in the axial direction of the screw conveyor with a circulation movement. The latter, however, affects the delivery of the generic feed conveyor. The sawtooth-like thread profile according to the invention improves the delivery rate in the present application, in which the feed must be picked up by the auger from the ground and moved laterally. The steep, oriented substantially perpendicular to the axis of the worm shaft, front thread flank of a sawtooth-like thread thereby reduces the Umwälzbewegung the recorded feed and improves the lateral sliding movement of the received feed in the axial direction of the worm shaft. As a sawtooth-like thread is understood in the context of the present invention, each thread profile, in which the thread profile extends flat in its by the worm shaft furthest removed sections compared to the front and rear thread flank.
    An advantageous embodiment provides that the sawtooth-like thread profile has a front thread flank facing the conveying direction, a rear thread flank facing away from the conveying direction, and an outer boundary surface extending in a helical manner around the worm shaft between the front and rear thread flanks, wherein the boundary surface is the front thread flank in the conveying direction. Due to the front thread flank superior boundary surface a nose-like projecting projection of the thread profile is created, which improves the absorption of the feed from the ground and thus the delivery rate. Preferably, it is proposed that the generatrix of the outer boundary surface extends obliquely to the worm shaft and opens in particular in the conveying direction of the screw conveyor. The inclination of the generatrix of the boundary surface relative to the screw shaft axis is preferably selected at a slightly acute angle, for example 20 °. There are different possibilities for the realization of a plastic casing provided according to the invention. An advantageous embodiment provides, for example, that the plastic sheath encloses a thread inner, which is designed as a plastic core, wherein the plastic core has a lower density than the plastic sheath. Such an embodiment is easy to manufacture, for example via an injection molding process. The worm shaft can be made in a conventional manner from a metallic material and be designed as a sheet metal drum. The plastic core of the screw thread can be injection-molded in the course of production of the screw conveyor to the sheet-metal drum, wherein it proves advantageous before roughening roughen the surface of the plate drum by sandblasting method to achieve a better connection of the screw thread to the plate drum. The plastic core is preferably formed from a foamed plastic, such as a foamed polyethylene. The plastic coating can be made subsequently in a spraying process by a suitable plastic, such as polyurethane, is sprayed onto the plastic core. The plastic coating is more resistant than the plastic core due to its higher density, but still has a higher elasticity compared to conventional steel threads.
    In order to increase the strength in such a construction, it is further proposed that a plastic strip arranged between the plastic casing and the plastic core extends below the boundary surface formed by the plastic casing. This plastic tape can be designed as a polyurethane strip and is placed on a production via an injection molding process before spraying with a plastic coating for the production of plastic coating on the plastic core. As an alternative to injection molding, it is also conceivable to glue a prefabricated plastic core onto the worm shaft and then to spray it with or without the use of an applied plastic tape with a sprayable and hardening plastic for producing the plastic coating.
    It is also conceivable to manufacture the screw thread according to the invention also by casting, in particular by means of a melt-core method in which a cavity remains inside the screw thread. Therefore, it is also proposed that the plastic sheath envelopes a thread inside, which is designed as a cavity. Instead of the cavity but also a suitably suitable casting core could be used.
    The invention will be explained in more detail below with reference to an embodiment with reference to the accompanying drawings. It show here the

    Reference is first made to Figs. 1 and 2, which show perspective views of an embodiment of a feed conveyor according to the invention as seen from above and below. The feed conveyor has a housing 1 with a front part 2 and a rear part 3. Inside the housing 1 are the wheel drive for the wheels 5 and / or rollers 6 of the mobile housing 1, the worm drive for the screw conveyor 4, and a generally rechargeable designed power supply for all the aforementioned components, in Fig. 2 are the two wheels 5a, 5b visible and the steering roller 6, with which the housing 1 can move about driving on a stable floor. Of course, other versions of the wheel drive are conceivable. The steering roller 6 is arranged in the rear part 3 and secured by a rotatable suspension 7. By different rotational positions of the suspension 7 and thus the steering roller 6 different directions of travel of the housing 1 can be realized. The rotational position of the steering roller 6 and the rotational speed of the wheels 5 are set via a control device (not visible in FIGS. 1 to 6), which in turn is connected to sensors which arranged the position of the housing 1 relative to external signal generators, such as in the stable floor Magnets, determine, compare with a given route and put appropriate control signals to the wheels 5 and the castor 6 to maintain the predetermined route.
    The operating voltage required for the power supply of the aforementioned components is provided by preferably rechargeable batteries. The controller recognizes the state of charge of the battery via a charge control and controls a charging station in good time. As soon as the feed conveyor has reached the charging station, it automatically connects to the charging station and starts the charging cycle. After a sufficient state of charge of the battery has been reached, the feed conveyor is available again for further trips. The control device is preferably connected via a wireless data connection with an external input device, via which a user-friendly programming and monitoring of the control device can be made.
    At a front part 2 of the housing 1, a bearing housing 8 is arranged, in which the screw conveyor 4 is received. The bearing housing 8 comprises a lateral frame part 9 as well as a cover 10 concentrically surrounding the conveyor screw 4 over a predetermined circumferential area. The cover 10 forms, with the lateral frame part 9, a receiving and conveying space for the feed captured by the conveyor screw 4, wherein in the exemplary embodiment shown lateral
    Frame part 9, the receiving and conveying space in the axial direction of the screw conveyor 4 bounded on one side. This side of the screw conveyor 4 is hereinafter referred to as the drive end. The opposite end of the screw conveyor 4 is not limited by a lateral frame part and thus designed as a free discharge end. The direction of rotation of the screw conveyor 4 is chosen so that the feed is transported in the direction of the free discharge end of the screw conveyor and ejected there.
    The drive motor for the screw conveyor 4 is located in the housing 1 and is connected via drive means with a drive shaft of the screw conveyor 4, wherein the drive means extend in the lateral frame part 9.
    With reference to FIGS. 3 to 6, the construction of the screw conveyor 4 according to the invention will be explained in a further consequence. The screw conveyor 4 comprises a screw shaft 4a and a screw thread 4b arranged on the screw shaft 4a. The worm shaft 4a is constructed drum-shaped and made approximately from a metal sheet. At the drive end of the screw conveyor 4, the worm shaft 4a is provided with a race 17, which can be pushed onto a journal or tubular bearing. The drive shaft (not visible in FIGS. 1 to 6) extends from the drive end of the screw conveyor 4 inside the worm shaft 4a to the hub 18 (see FIG. 6) held by a bearing cover 19 within the worm shaft 4a. The drive shaft is inserted into the hub 18 and sets the screw conveyor 4 in rotation. The drive shaft is driven by the running in the lateral frame part 9 drive means.
    At the free discharge end of the screw conveyor 4, the screw shaft 4a is provided with a safety cover 11. Within the worm shaft 4a extend in the illustrated embodiment push rods 12 which rest at one end on the safety cover 11 and are secured at its other end by means of bearing bushes 13 to a pressure ring 14, wherein the pressure ring 14 by means of a tension spring 15 in the direction of the safety cover 11 stretched becomes. On the inner shell of the worm shaft 4a stabilizing plates 16 may also be arranged for the push rods 12, which are welded to the push rods 12 and form a basket-like structure with them. In lateral loads on the screw conveyor 4, which are exerted approximately by the cattle, the pressure ring 14 is moved against the restoring force of the tension spring 15 and thereby triggers an electrical impulse, which switches off the drive immediately. The safety cover 11 is executed in the illustrated embodiment with a raised executed central region and a recessed relative to the central region edge region, wherein the
    Free space between the edge region and the screw shaft 4a is provided with a plastic filling 20.
    Along the outer circumferential surface of the screw shaft 4a extends the screw thread 4b, which has a layer structure with a plastic core 21 and a plastic sheath 22 in the illustrated embodiment, wherein the plastic core 21 has a lower density than the plastic sheath 22. The plastic core 21 is preferably made of a foamed plastic formed, such as a foamed polyethylene or a foamed polyurethane. The plastic sheath 22 is wear-resistant and elastic and can be made of polyurethane. Preferably, it also has food suitability because it comes into contact with the feed for the livestock. The worm thread 4b can be injection-molded in the course of the production of the screw conveyor 4 to the metallic worm shaft 4a, wherein it proves advantageous in this case to roughen the shell surface of the worm shaft 4a by sandblasting before injection molding, for a better connection of the worm thread 4b to reach the worm shaft 4a. In casting process this procedure is unnecessary.
    The sawtooth-like thread profile has a forward thread flank 24 facing the conveying direction R, a rear thread flank 25 facing away from the conveying direction R, and an outer boundary surface F extending in a helical manner around the worm shaft 4a between the front and rear thread flanks 24, 25, wherein the boundary surface F the front thread flank 24 projects beyond in the conveying direction R. Due to the front thread flank 24 projecting boundary surface F a nose-like protruding projection 26 of the thread profile is created, as mentioned, the inclusion of the feed from the ground and thus improves the capacity of the screw conveyor 4. It is advantageous if the generatrix of the outer boundary surface F extends obliquely to the screw shaft 4a and opens in particular in the conveying direction R of the screw conveyor 4. The inclination of the generatrix of the boundary surface F relative to the screw shaft axis is preferably selected at a slightly acute angle, for example 20 °. In Fig. 6, however, no inclination of the generatrix of the boundary surface F is apparent, which thus runs parallel to the axis of the worm shaft 4a.
    The worm thread 4b does not have the injury potential of a steel thread due to its structure according to the invention, since the hardness and the torque of the rotating worm thread 4b are lower. The inventive
    Plastic construction also allows greater design options in terms of thread shape, without significantly increasing the cost and weight of the structure. For example, it is easily possible to design the flank shape of the worm thread 4b such that the plastic casing 22 forms a sawtooth-like thread profile. Radially projecting edges and their sharpening in the course of use are avoided in such an embodiment. In order to increase the strength in such a construction, a plastic strip 23 arranged between the plastic casing 22 and the plastic core 21 is inserted below the boundary surface F extending in the outermost peripheral section of the screw thread 4b as part of production by means of injection molding. This plastic strip 23 may be designed as a polyurethane strip.
    The inventive construction of the worm thread 4b has several advantages. First, the risk of injury is reduced, since the plastic structure according to the invention has much less potential to inflict injuries on an operator or an animal than a circumferential steel thread. In addition, the conveying performance of the screw conveyor 4 is improved by means of the sawtooth-like thread profile. The feed conveyor according to the invention throws the food loosened to the feed table, wherein the feed is mixed at the same time, and leaves a clean feed passage.
