BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a fertilizer conveying system built into a fertilizer channel and to a first conveying section provided with an endless, circumferential drive chain driven, reciprocating impact bar, and to a second conveying section provided with an endless conveyor , circumferential chain, rope or similar means attached to the scraper, tear or similar means, in which a guide wheel for the endless drive chain along with a rear guide wheel for the second transport section is arranged on a horizontal shaft.

Fertilizer transport plants are known, which consist of two transport sections. One of the transport sections includes, among other things, a reciprocating shock bar, at which limited hinged scrapers, rakes 15 or similar means are hinged at certain distances. The thrust bar is generally enclosed on the side of a manure. As the thrust bar moves in the conveying direction, the scrapers or similar means are positioned across the conveying direction and push the manure forward in front of it. At the subsequent return stroke, the scrapers or similar means swing toward the thrust bar and slide in this position past the manure piles, in order to stand back across the thrust bar at the next finishing stroke, and consequently step the manure forward in front of it. The second transport section, which is generally directed obliquely upward from the manure gutter, contains an endless orbital chain, a rope or similar means, to which are also attached scrapers, rakes or similar means moving in the region corresponding to the most inclined part. of the manure gutter. As the scraper, tear 30 or similar means is moved upward by the rope, the scraper, tear or similar means displaces the manure in front of it until the end of the manure gutter, after which the manure at the end of the manure gutter falls. At the subsequent setback, the scraper, tear or similar means slides back down the fertilizer channel to slide in the area corresponding to its lower end position over the manure pile shown there during the step 142012 and again at the following working stroke. the manure pile forward towards the end of the manure gutter. In connection therewith, it is known to operate the endless orbital chain, rope or similar means by means of the drive for the reciprocating thrust bar. It is also known next to the reciprocating thrust bar to place an endless chain in the horizontal position, which is driven by the drive motor, which is provided with abutments which with their orbital abut 10 corresponding abutments on the thrust bar and move it forward. and back. By means of this drive, the endless orbital chain, rope or similar means can also be operated on the inclined second transport section (conveyor). However, since the length of the conveyor path in the endless orbiting conveyor chain does not generally correspond to the stroke of the reciprocating thrust bar, it is necessary to incorporate a corresponding gear so that at each stroke of the forward and backbone reciprocating push-rod also determines the scraper, tear or similar means the total length of the high-lying fertilizer ring.

The known fertilizer conveyor system and its drive gear are convenient, since a gear must be incorporated between the reciprocating push rod drive and the inclined carrier drive. This is costly in manufacturing and susceptible to interference. The fertilizer transport system therefore requires an extra care.

Swiss Patent No. 429,586 also discloses a fertilizer conveying system having a first horizontally conveying conveying section in the form of a conveyor with carriers pivotally mounted on a reciprocating shock bar and with a sloping connection connected to the first conveyor. a second conveying section in the form of an inclined lift conveyor with a tear as the carrier.

35 The thrust bar is arranged on one side of a manure channel 142012 and is pivotally connected to a downwardly extending connecting rod by means of a slot in the bottom of the manure gutter. This is hinged on a first drive chain, which is also carried below the manure gutter in a uncovered grave. The drive chain extends 5 on both sides over also steering wheels located in the tomb, where on the shaft of the steering wheel lying in the transport direction is a drive disk for a drive motor.

The known fertilizer conveyor system may be provided with two different performance liners for a lift conveyor. In the one embodiment, on the shaft of the drive wheel on both sides, outside the side wall of the manure gutter and the sidewall of the inclined lifting conveyor, two guide wheels are mounted for two drive chains for the inclined lifting conveyor. In addition, the shaft is provided with a V-belt pulley which is driven by a V-belt of an engine. The oblique lift conveyor consists of a conveyor ring with side vanes 20. On these, rollers run in a frame, which rollers are mounted on fixed bearing arms. The bearing arms carry the rivers. The arms forming in the conveying direction and connecting rods on the frame are hinged to the two endless chains, which are arranged parallel to and outside the conveyor, by means of pins. The chains are passed at their lower end over the sprockets already mentioned and at their upper end over sprockets. The upper steering wheels sit on a continuous shaft, while the lower steering wheels 25 are not connected to each other by means of a common shaft.

The drive sprockets for the drive chains for both transport sections are dimensioned to the same sprocket numbers per head. unit of time.

First, the known plant has the disadvantage that the drive for the first transport section lies below the fertilizer trench in a covered grave. In addition to donkeys, manure and solid constituents can accumulate in this tomb, so that the drive is not only subjected to great wear but also disrupted. A further disadvantage consists in the fact that in order to operate the inclined lift conveyor two chain strings are needed, which are arranged on both sides outside the inclined lift conveyor side wings. As a result, the plant will fill a lot 14 142012. Furthermore, a cumbersome connection of two connecting rods to these chains, which are connected to the frame to the rivers, is required. This frame is provided with rollers running on the side wings, so that there must be guide rails there.

Finally, the passage of the lower drive shaft, which carries the front steering wheel to the first drive chain and one rear steering wheel to the second drive chain, causes difficulties through the walls of the tomb. Disadvantages also arise from the fact that during operation one of the two drive chains in the oblique lift conveyor is passed over the steering wheel shaft located on its upper head end. Thereby, a delay occurs. operation of the second drive chain to the oblique lift conveyor so that the rake trolley driving rods do not accl - 1-5 be accurately operated simultaneously in one or the other direction.

The known fertilizer conveyor system may also be provided with an oblique lift conveyor designed in a different way, the horizontal conveyor being practically the same. On the forward drive shaft of the drive chain, a drive wheel is attached to a chain drive leading to the second transport section. This consists of two chains, which are passed along the inside of the side vanes of the oblique lift conveyor, and which run over two guide roller pairs. The lower guide wheels lie at the inner walls of the oblique lift conveyor and are fixed to the shaft on which also the drive wheel of the drive chain sits. The two upper steering wheels are located outside the inclined upwardly extending conveyor.

A number of rivers are attached to the two drive chains. The lower guide wheels lie in a trough located below the 50-point throwing point in the manure gutter. The operation of this fertilizer conveyor differs from the fertilizer conveyor described above in that it does not need a specific ratio of operation when operating both the horizontal conveyor and the inclined lift conveyor as these conveyors do not intersect.

The disadvantages of the horizontal conveyor mentioned above also apply here. The oblique lift conveyor has the disadvantage that two drive chains are again present, whereby a through shaft is passed through the pick-up area of the oblique lift conveyor, which can lead to accumulation in the fertilizer conveyor. The plant has a complicated construction and is subject to strong wear.

Also known from Austrian patent specification No. 216,416 is a fertilizer conveying plant with a lifting conveyor and a stepwise working conveyor for supplying fertilizers. The latter conveyor is again designed as a thrust conveyor, whereby on both ends of the thrust bar a continuous rope pull which is reciprocated by a reversible motor is engaged. Furthermore, the rope pull is guided over 15 three guide rollers to a rope drum, which wraps the rope pull. The rope drum is located near the side wall of the oblique lift conveyor and is directly connected to the motor. This motor further operates by means of a rope drum an endless rope pull which is guided at both ends of the inclined lift conveyor 20 over vertically mounted guide rollers. On one strand (part) of the rope pull is mounted a forklift carrying a fork. The fork of the fork is pivotally suspended about or together with a shaft. The fork is guided by means of U-shaped guides arranged on both side walls into which the fork carriage rods engage. The connecting strips of these rods carry the bearing for the rotating shaft of the fork. The shaft can also engage in U-shaped guides. The two rods are connected to each other by means of a segment provided with holes for insertion of stops. By changing the bar between these stops, the opening angle of the teeth can be changed. The stops are arranged so that the fork, when transferring fertilizer supplied from the horizontal conveyor to the intersection of the two conveyors, opens in the direction of the second conveyor, so that the fork can slip away over the fertilizer. At the working stroke, the fork is held in the gripping position by means of a stop. This fertilizer transport system has the major disadvantage that the direction of rotation of the drive motor 6 142012 must be changed continuously at the end of each idle stroke or working stroke, respectively. The system requires a corresponding drive motor adjustment device.

The object of the invention is to provide a fertilizer conveying plant of the type initially referred to, which fertilizer transport plant, and in particular its drivetrain, can be designed in a very simple manner and which fertilizer transport plant manufacture, assembly and fitting can be simplified, and which plant's structural parts are greatest possible extent is protected against corrosion. Furthermore, a long transitional stretch between the first transport section (horizontal conveyor) and the second transport section (inclined lift conveyor), which requires a redundant and expensive transport part, must be avoided, and the structural parts of the drive unit must be designed in the simplest possible way.

The fertilizer transport system according to the invention is characterized in that the endless drive chain driving the first transport section is arranged above the thrust bar, and that the guide wheels for the 2Q drive chain lying higher than the second steering wheel of the drive chain are located, and that said steering wheels are located in the area of the fertilizer gutter. Since the endless chain of the first transport section is located above the thrust bar and the manure gutter, the entire manure transport system drive is freely available. This results in 25 easy assembly and fitting of the fertilizer transport system.

In addition, the drivetrain is not exposed to corrosion or wear due to dandruff and manure. By controlling the wheels of the first and second transport sections in the area of the fertilizer trench, it is achieved that the drive chain for the second transport section (lift conveyor) lies in the area of the fertilizer trough and can practically intervene in the middle of the scrapers, rakes or similar means, whereby this part of the fertilizer transport system get a simple and clear structure.

It is also obtained that it is possible to connect the horizontal transport section (lift conveyor) side walls with above the endless, circular drive chain connected connecting lugs, thereby increasing the stability of the second transport section (lift conveyor). Since the driving wheel lying in the direction of the second transport section is positioned higher than the second driving wheel of the drive chain, a shortening of the construction of the system is obtained, since the guide path of the second transport section (the lift conveyor) under its rear steering wheel can extend into an arc and be connected to it. first transport section (the horizontal conveyor).

According to the invention, the drive chain for the first transport section may be provided with stops which alternately abut the upper and lower abutment surfaces of a carrier when rotating the drive chain, soot. is arranged on a carriage parallel to the drive chain, and which is provided on its underside with a protruding part, wherein on both sides of the protruding part and partly the thrust rod is hinged a pull and thrust rod. In this embodiment, the advantage is obtained by using a robust drivetrain which, in the position according to the invention above the manure gutter, is corrosion protected and practically indefinitely durable.

Furthermore, the manure transport system according to the invention can be designed such that a drive motor engages with the second steering wheel of the drive chain. This positioning of the drive motor enables easy monitoring and care of the fertilizer transport system. Said location of the drive motor is also convenient with respect to the center of gravity of the fertilizer transport system.

The invention is explained in more detail below with reference to the drawing, in which: FIG. 1 is a side view of an embodiment of a fertilizer transport system according to the invention; and FIG. 2 the fertilizer transport system seen from above.

8 142012 In the drawing, one end 1 of a fertilizer channel is shown, which is placed at the bottom of a stable not shown. On the bottom and side of the manure gutter is a reciprocating thrust bar 2, on which are hung scrapers 3 or similar 5 members. At a working layer in the direction of arrow P1, scrapers 3 will move across the transport direction and push fertilizer forward in front of them. As the thrust bar 2 moves in the opposite direction, the scraper 3 swings in towards the thrust bar 2 until it abuts against it and in this position slides forwards in fertilizer piles.

To the manure gutter that ends outside the barn is connected by means of a curved piece 4 an inclined upwardly extending manure channel 5. U-shaped guide rails 6 are arranged on the upper side of the manure gutter, which are arcuate at their lower part 7. In the guide rails 6 are guided wheels, slides or similar means 8 on a guide part, such as a trolley 9, which can be a tear truck.

On the carriage 9, in the illustrated embodiment, a plurality of loose rakes or teeth 10 are pivotally mounted, the pivoting movement 20 being limited such that the rakes or teeth cannot pivot downwardly past that of FIG. 1, but may well swing upward in the direction of arrow P2. When the rake 9 has reached its upper end position (not shown), the rakes or teeth 10 can slide over the fertilizer piles lying there, and then move back to their normal downward position.

The carriage 9 is connected by means of a drawbar 11 in a manner not shown in detail to a chain 12. This carries a pin over which a sleeve fixed to the drawbar 11 engages.

The chain 12 is passed at its upper end over a steering wheel 13 and at its lower end over a rear steering wheel 14. The steering wheel 13 is slidably mounted in the direction of the chain 12, so that an extension of the chain 12 by displacement of the steering wheel 13 can be offset. The steering wheel 13 is further arranged so that the carriage 9 can reach such a high level that the fertilizer included with the 10 is thrown out at the place 15.

The rear steering wheel 14, together with a steering wheel 16, is mounted on a drive shaft described below on a shaft 14a, which is mounted above the parts 1, 4 and 5 of the fertilizer trough so that the tear trolley 9 can move freely.

A drive chain 17 is passed over the steering wheel 16 and at the other end over another steering wheel 18 with which a drive motor 19 engages. The drive motor 19, together with the steering wheel 18, can also be slidably mounted in the direction of the drive chain 17 so that extensions in the longitudinal direction of the drive chain 17 can be offset. The drive chain 17 is provided on each side with a stop 20.

The abutments 20 abut the abutment of the drive chain 17 against abutment surfaces of a carrier 21 which is secured to a carriage 22.

This is mounted on both sides by means of rollers 23 in U-shaped guide rails 24 which are parallel to the drive chain 17. The carriage 22 is provided on its underside with a protruding part 25 on which a pull and push rod 26 is hinged. which is hinged at its other end on the first transport-2Q sectional thrust bar 2.

The guide rails 24 and the drive chain 17 are inclined, whereby the second steering wheel 18 or the driving motor 19 is deeper than the steering wheel 16. This simplifies the structure of the fertilizer transport system.

The ratio of the diameters of the steering wheels 14 to 16 is determined such that the fertilizer supplied during one or an integer multiple of the working stroke of the thrust bar 2 is moved in a working stroke by means of a row 10 from the point of delivery to the point of departure 15.
