Abstract

The invention relates to a grain conveyor chain for a harvesting vehicle, having a chain of standard chain links and a plurality of scoops, wherein the scoops are fastened to the chain and the standard chain links have an inner plate, an outer plate, a pin and/or a sleeve, and wherein each scoop is in direct contact with a standard chain link.

Description

Grain conveying chain
Technical Field
The invention relates to a grain conveyor chain for a harvesting vehicle, comprising a chain of standard chain links and a plurality of scoops, wherein the scoops are fastened to the chain and the standard chain links comprise inner plates, outer plates, pins and/or bushings.
Background
A harvester (e.g., a combine) has a conveyor chain that conveys harvested and threshed material (e.g., grain) from a screw conveyor in a lower region of the harvester into a grain bin (also referred to as a grain conveyor chain or hoist chain) in an upper region of the harvester. For this purpose, an endless chain provided with a bucket, which has an upward section and a return section, runs between two sprockets in the elevator housing. Due to the frequent use of agricultural machinery outdoors, these conveyor chains are exposed to weather-related influences as well as dust and dirt.
Document US 2018/0334329 A1 discloses a grain conveyor chain (hoist chain) having a conveyor bucket. The bucket is fastened by means of two screws on the corner bracket, which in turn is fastened to the outer chain plate of the conveyor chain.
US 10 462 973 B2 also discloses a grain conveyor chain, the conveyor bucket of which is also fastened to the carriage. The brackets are inclined plates which are fastened to the outer chain plates of the conveyor chain. The bucket is fastened using two screws on the tilt plate.
A disadvantage of both grain conveyor chains described here is that, in addition to the conveyor bucket, an additional element (bracket) is required to fasten the conveyor bucket to the chain. The weight and production costs of the conveyor chain are thus increased, and in the event of damage, the conveyor chain is complicated to repair.
Disclosure of Invention
The invention is therefore based on the object of providing a grain conveyor chain for a harvesting vehicle with which a higher conveying capacity of harvested grain per unit time can be achieved, which at the same time is cost-effective and operates reliably in use, can be produced cost-effectively and is easy to repair in the event of damage.
It is also an object of the present invention to provide a grain conveyor chain with which a higher conveying capacity of harvested grain per unit time can be achieved, which is simple and cost-effective to install and at the same time can be operated cost-effectively and reliably in use; and to provide a bucket for mounting on a grain conveyor chain. In addition, it is an object of the invention to provide a method for fastening a bucket on a grain conveyor chain, with which method the bucket can be fastened on the chain quickly and cost-effectively.
This object is achieved by means of a bucket for mounting on a grain conveyor chain as claimed in claim 1. Further advantageous embodiments of the invention are described in the dependent claims 2 to 16.
A bucket according to the present disclosure has a bucket body with a bucket surface. The bucket surface is designed to contain the material to be transported. In addition, the bucket has a fastening element which is provided and suitable for the purpose of fastening directly on a standard chain link. Direct fastening in the sense of this document refers to fastening which can be managed without adapters or additional parts, such as tilting plates, as is commonly used in these applications. The fastening element of the bucket is thus in direct contact with one or more standard links.
In a development of the bucket according to the invention, the bucket additionally has two flanks, the side flaps enclose the chain on the outer plates of the chain. The distance of the side flaps from each other is dimensioned in such a way that the side flaps directly adjoin the chain, in particular the outer plates. Thus, there is no space between the chain and the bucket, and the transported grain does not fall between the chain and the bucket in operation. In addition, the depth of the flank corresponds to the height of the grain conveyor chain, so that a chain line formed by the rear side of the chain facing away from the scoop ends at the edge of the flank of the scoop running in parallel. There is therefore no space behind the chain where grain could fall down the bucket.
In another embodiment of the invention, the bucket is formed as a single piece. The bucket advantageously has only one part, or additional parts are connected to the bucket in a form-fitting manner. Thus, the bucket can be produced in mass production by means of known methods, in particular in the case of buckets made of plastic. The bucket can then be produced cost-effectively, for example by means of an injection molding method. A component is to be understood in the sense of this document as a single piece consisting of only one part or comprising a plurality of parts which cannot be detachably connected (e.g. multi-part injection moulding). In an optional development of the invention, the bucket is formed as a single piece together with the fastening element.
In a further embodiment of the invention, the bucket has a fastening element, for example in the form of a fastening opening, through which a pin can be guided for fastening the bucket on a standard link. By means of the pin, the bucket is fastened directly on the standard link, such as a pin or an outer plate of the chain.
In another embodiment of the invention, the fastening elements are arranged on one or both flanks of the bucket. Preferably, the two flanks each have a fastening element, which are aligned with one another in such a way that a pin for fastening the bucket on a standard link of the chain can be guided through the fastening elements.
In a development of the invention, each side flap has two fastening elements, for example in the form of fastening openings. The fastening openings are aligned with one another in pairs in such a way that a pin can be guided through both of the respective fastening openings aligned with one another, with which the bucket can be fastened on a standard link of the chain.
In another embodiment of the invention, the fastening element has a first reinforcement. The first reinforcement reinforces the fastening element in such a way that the pin which can be guided through the fastening element has only little play and, as a result, the bucket can be fastened by means of the pin without play on the standard links of the chain.
In another embodiment of the present invention, the first reinforcement is made of a material different from the bucket surface. The bucket surface is preferably formed of plastic, which can be produced cost-effectively, for example by means of injection moulding. In order to increase the service life of the fastening element, the first reinforcement is made of a material that increases the strength and the breakage resistance of the fastening element.
In a development of the invention, the first reinforcement is made of metal. A first reinforcement made of metal (e.g. aluminum or steel) fulfills this need and can be produced in large quantities cost-effectively.
In another embodiment of the invention, the first reinforcement constitutes only a part of the side flap. In order to reduce the weight and cost of the bucket, only the portion of the side wing that is subjected to the highest stresses in operational operation is reinforced.
In another embodiment of the present invention, the first reinforcement is a sleeve. The bushing reinforces the fastening element in such a way that the pin which can be guided through the fastening element has only little play and, as a result, the bucket can be fastened by means of the pin without play on the standard links of the chain.
In another embodiment of the invention, the first reinforcement has the form of an outer plate. In an optional development of the invention, after fastening the bucket on the chain, the outer plate of the first reinforcement replaces the outer plate of the chain link on which the bucket is fastened.
In another embodiment of the invention, the reinforcement is embedded in the fastening element. The first reinforcement is non-removably attachable to the fastening element. The bucket forms a one-piece component and can be quickly replaced in the event of maintenance.
In an advantageous embodiment of the invention, the bucket has a bucket surface reinforcement. The bucket surface reinforcement reinforces the bucket body against stress under load in such a way that the bucket does not deform under load and, therefore, can convey more material per unit time or even break.
In another embodiment of the present invention, the bucket surface reinforcement is a support structure below the bucket surface. The support structure effectively prevents the bucket body from deforming under load and at the same time has a light weight. For example, the support structure may be formed by support ribs. In addition, a stay made of a material different from the bucket may be provided as the support structure. The bucket surface reinforcement may be designed in such a way that it is integrated, for example, by injection moulding into the bucket during production of the bucket.
In a development of the invention, the bucket surface reinforcement of the bucket is made of a material different from the bucket surface. In order to increase the strength and especially the breakage resistance of the bucket surface, the reinforcement is made of a material that increases the strength and breakage resistance of the bucket surface.
In another embodiment of the present invention, the bucket surface is made of plastic and the bucket surface reinforcement is made of metal. The bucket surface is preferably made of plastic, which can be produced cost-effectively, for example by means of injection moulding. In order to increase the strength and especially the breakage resistance of the bucket surface, the reinforcement is made of a material that increases the strength and the breakage resistance of the bucket surface.
In a development of the invention, the bucket is fastened to the grain conveyor chain according to the invention. The grain conveyor chain has a chain. The chain has standard links with inner plates, outer plates, pins and/or sleeves.
In another embodiment of the invention, the bucket and/or the fastening member have dimensions corresponding to one of the following: chain parts, for example, sleeves, pins, inner and/or outer plates; and/or chains according to the british standard (DIN 8188) or ANSI standard (DIN 8187). These dimensions of the bucket and/or the fastening member may be one or more dimensions of the standard chain from the following group of dimensions: pin and/or sleeve diameter, outer distance of opposing outer plates, inner distance of opposing inner plates, distance between two pins, distance between two sleeves, length of chain link, length of inner plates, length of outer plates, or any other dimension from the dimension of a standard chain or chain component thereof according to british standard (DIN 8188) or ANSI standard (DIN 8187).
This object is also achieved by means of a grain conveyor chain for a harvesting vehicle according to the invention as claimed in claim 17. Advantageous embodiments of the invention are described in the dependent claims 18 to 23.
The grain conveyor chain according to the invention has a chain. The chain has standard links with inner plates, outer plates, pins and/or sleeves. The grain conveyor chain also has a plurality of scoops secured to the chain. According to the invention, the bucket is in direct contact with the standard chain links. In particular, the bucket is fastened on the chain and is in direct contact with a standard link, so that there is no space between the chain and the bucket. This effectively prevents the material carried on the bucket from falling off during operation and the grain conveyor chain according to the invention operates more efficiently.
In a development of the invention, the bucket is fastened directly to the standard chain link. The bucket therefore does not require additional brackets or spacers to secure the bucket to the chain. Since the bucket is fastened directly to the standard chain link, the grain conveyor chain according to the invention can be produced more easily and more labour-effectively than previously known conveyor chains. The grain conveyor chain according to the invention can thus be operated more efficiently.
In another embodiment of the invention, the bucket is fastened directly to the outer plate on the chain by means of a pin. The pin may be designed in such a way that it both secures the bucket and at the same time acts as a chain pin. Thus, no additional components are required to fasten the bucket to the chain, which is lighter than a comparable grain conveyor chain and which in addition can be produced more cost-effectively.
In a further embodiment of the invention, the bucket has a fastening element for fastening the bucket on the standard link. In an optional embodiment, the fastening element is an opening through which a guide pin passes, whereby the bucket is fastened directly to standard links of the chain, such as the outer and/or inner plates and the pin.
In a development of the invention, the pin as a chain pin represents a joint between an inner plate and an outer plate of the chain. The pins are arranged in such a way that the bucket is kept perpendicular to the chain in the upward region (load side) in operational operation by its own weight and the material being carried on the bucket surface.
In another embodiment of the invention, each bucket is fastened to the chain by means of two pins. This makes the chain-bucket connection more stable, said pins simultaneously serving as chain pins of the chain link on which said bucket is fastened. No additional components are required to secure the bucket to the chain.
The object is also achieved by means of a method for fastening a bucket on a grain conveyor chain as claimed in claim 24. Further advantageous embodiments of the invention are described in the dependent claims 25 to 37.
The method for fastening a bucket to a grain conveyor chain according to the invention has two method steps: in a first method step, the bucket is positioned relative to a standard link of the chain. The standard links are inner plates, outer plates, pins and/or sleeves. In a second method step, the bucket is fastened directly to the standard chain link of the chain. The bucket therefore does not require additional brackets or spacers to secure the bucket to the chain. Since the bucket is fastened directly to the standard chain link, the grain conveyor chain according to the invention can be produced more easily and more labour-effectively than previously known conveyor chains. The grain conveyor chain according to the invention can thus be operated more efficiently. In particular, the bucket is fastened on the chain and is in direct contact with a standard link, so that there is no space between the chain and the bucket. This effectively prevents material carried on the bucket from falling off during operation and the grain conveyor chain according to the invention operates more efficiently.
In another embodiment of the invention, the bucket has two side wings, each side wing having a fastening element. The bucket is fastened to the grain conveyor chain by means of the fastening element. The distance between the side flaps is equal to the chain width and is dimensioned in such a way that the side flaps directly adjoin the chain, in particular the outer plate. Thus, there is no space between the chain and the bucket, and the transported grain does not fall between the chain and the bucket in operation.
In another embodiment of the invention, the bucket is fastened directly to the outer plate on the chain by means of pins. The pin may be designed in such a way that it both secures the bucket and at the same time acts as a chain pin. Thus, no additional components are required to fasten the bucket to the chain, which is lighter than a comparable grain conveyor chain and which in addition can be produced more cost-effectively.
In a development of the invention, each bucket is fastened to the chain by means of two pins. This makes the chain-bucket connection more stable, said pins simultaneously serving as chain pins of the chain link on which said bucket is fastened. No additional components are required to secure the bucket to the chain.
In another embodiment of the invention, the bucket has a fastening element, a pin for fastening the bucket on the standard link is guided through the fastening element. The pin may be designed in such a way that it both secures the bucket and at the same time acts as a chain pin. Thus, no additional components are required to secure the bucket to the chain.
In another embodiment of the invention, a first reinforcement is arranged on the fastening element. The first reinforcement reinforces the fastening element in such a way that the pin which can be guided through the fastening element has only little play and, as a result, the bucket can be fastened by means of the pin without play on the standard links of the chain.
In another embodiment of the invention, the first reinforcement is made of a material different from the bucket surface of the bucket. The bucket surface is preferably formed of plastic, which can be produced cost-effectively, for example by means of injection moulding. In order to increase the strength and especially the breakage resistance of the bucket surface, the reinforcement is made of a material that increases the strength and the breakage resistance of the bucket surface.
In a development of the invention, the first reinforcement is made of metal. In order to increase the strength and especially the breakage resistance of the bucket surface, the first reinforcement is made of a material that increases the strength and the breakage resistance of the bucket surface. A first reinforcement made of metal (e.g. aluminum or steel) fulfills this need and can be produced in large quantities cost-effectively.
In another embodiment of the invention, the first reinforcement constitutes only a part of the side flap. In order to reduce the weight and cost of the bucket, only the portion of the side wing that is subjected to the highest stresses in operational operation is reinforced.
In another embodiment of the invention, a sleeve is arranged on the fastening element as the first reinforcement. The bushing reinforces the fastening element in such a way that the pin which can be guided through the fastening element designed as a fastening opening has only little play and, as a result, the bucket can be fastened by means of the pin without play on the standard chain links of the chain.
In a further embodiment of the invention, the first reinforcement is arranged on the fastening element in the form of an outer plate. After the bucket is fastened to the chain, the first reinforcement replaces the outer plate of the chain link on which the bucket is fastened.
In another embodiment of the invention, the reinforcement is embedded in the fastening element. The first reinforcement is connected to the fastening element in a form-fitting manner, the bucket forming a one-piece component and being quickly replaceable in the event of maintenance.

Detailed Description
Fig. 1 shows an exemplary embodiment of a grain conveyor chain 1 according to the invention. The grain conveyor chain 1 is typically an endless circulating chain, in this and the following figures only one area of the grain conveyor chain 1 is shown. The grain conveyor chain 1 has a chain 100. In this and the following exemplary embodiments, the chain 100 is designed as a roller chain with standard links. The standard links are alternating inner plates 110 and outer plates 120, which plates are connected to each other by chain pins 140 guided in chain bushings (not shown). The rotatable roller 130 encloses a chain sleeve and a chain pin 140 and is operatively connected to a drive member, such as a sprocket (not shown).
A plurality of buckets 200 are secured to the chain 100, two of which buckets 200 are shown secured to the chain spaced apart from one another in this figure by way of example. In this exemplary embodiment, the bucket 200 is fastened directly to the outer plate 120 of the chain 100 using a pin 240. For this purpose, the bucket 200 has two flanks 201, 202, each of which has a fastening element 211, 212. The fastening element shown here is a fastening opening having an inner diameter equal to the outer diameter of the pin 240. The wings extend above (201, 202) and below (203, 204) the bucket surface 250. The fastening elements 211, 212 are aligned with each other. The pin 240 has the same diameter as the chain pin 140, but at the same time, the pin has a greater length.
To secure the bucket 200 on the chain 100, the bucket 200 is positioned in a manner such that the securing openings 211, 212 are aligned with the openings of the respective two opposing outer and inner plates 120, 110 and the chain bushings. The pin 240 is then guided through the fastening elements 211, 212, the outer plate 120 and the inner plate 110 and the chain bushing in such a way that the pin 240 both fastens the bucket 200 on the chain 100 and acts as a chain pin 140. In the fastened state, the bucket 200 can pivot about the pin 240 as a joint axis. In running operation, the bucket 200 in the load side of the chain 100 is pressed against the chain 100 by its own weight and the weight of the material being carried on the bucket surface 250, and thus remains substantially perpendicular to the chain 100.
The chain 100 is a standard chain according to the british standard (DIN 8188). The bucket 200 with the fastening elements 211, 212 is formed in one piece. The inner distance between the fastening elements 211, 212 corresponds to the width of a standard chain (outer distance of the outer plates). The diameter of the holes in the fastening elements 211, 212 corresponds to the outer diameter of the pins. In an alternative embodiment (not shown here), the chain 100 is a standard chain according to the ANSI standard (DIN 8187). The dimensions of the one-piece bucket here therefore correspond to a chain according to the ANSI standard (DIN 8187).
Fig. 2a to 2d show different views of the bucket 200. Each dipper 200 has a rectangular shape and has a dipper surface 250 on an upper side of a dipper body 260 (fig. 2 a) for carrying grain or other material. The bucket surface 250 has a depression 251 to better carry the material.
In the rear region, the bucket 200 has a raised portion 252, which prevents the transported material from falling off. At the same time, raised portion 252 improves the structural integrity of bucket 200. The bucket body 260 is preferably made of a mass producible material, such as a polymer. The recess 205 is also arranged at the middle in the rear region. The recess 205 is dimensioned in such a way that it encloses the chain 100 in the state in which it is mounted on the chain 100. The side wings 201, 202, 203, 204 (each having two fastening elements 211, 212, 213, 214) are arranged on opposite sides of the recess 205. Each two opposing fastening elements 211, 212, 213, 214 are aligned with each other.
The bucket 200 has a bucket surface reinforcement 230 on the underside (fig. 2 c). The bucket surface reinforcement 230 is designed as a support structure and effectively prevents the bucket 200 from deforming or breaking under load. The reinforcement 230 may be made, in whole or in part, of a different material than the bucket body 260; preferably metal is used, for example in the form of aluminium stays.
In this exemplary embodiment (fig. 2 b), the bucket 200 also has flanks 203, 204 on the underside, which, like the flanks 201, 202 on the upper side of the bucket 200, have fastening elements 213, 214 aligned with one another. Fig. 2d shows the bucket in its side view. The fastening elements 211, 213 have first reinforcements 221, 223, respectively. These first reinforcements 221, 223 are preferably metal sleeves which are inserted into the fastening elements 211, 213 by press-fitting and in a form-fitting manner and are connected thereto.
To secure the bucket 200 on the chain 100, the bucket 200 is positioned in a manner such that the fastening elements 211, 212 are aligned with one chain bushing 130 and the fastening elements 213, 214 are aligned with the other chain bushing 130. The first pin 241 is then guided through the fastening elements 211, 212 and the chain sleeve 130, and the second pin 242 is guided through the fastening elements 213, 214. Thus, the two pins 241, 242 fasten the bucket 200 directly to the chain 100, the two pins 241, 242 being at the same time chain pins of the chain 100.
Fig. 3a to 3d show different views of an exemplary embodiment of a bucket 200 with a first reinforcement 225 in the form of an outer plate. Wings 201, 202, 203, 204, each of which has two fastening elements in the form of fastening openings 211, 212, 213, 214, are also arranged on the upper side (fig. 3 a) and the lower side (fig. 3 c) of the bucket 200 around the recess 205.
