Fertilizer or seed distributor

The invention relates to "a distributor for the distribution of particulate material" ζ · Β · τοη fertilizers or · seeds on the ground ·

Ea fertilizer distributors have been proposed which are intended to cover a relatively large area of the soil in one pass of the distributor and which have a transverse bar from which the fertilizer is distributed . One of the difficulties in creating a satisfactory seed distributor of this type is that the bars are particularly cumbersome when the distributor

drives to and from the point where the distribution is to be carried out and when it is controlled. One Another difficulty is to ensure a constant distribution of the mean along the beam. Yet another difficulty is preventing loss of fuel when controlling the manifold and when he is driving, and in getting the desired fertilizer flow .after steering and driving.

The invention has for its object to at least "avoid some of the above disadvantages and one To create a fertilizer distributor capable of the fertilizer over a relatively large area during each pass of the manifold across the floor to distribute.

According to the invention, the distributor for distributing particulate material on the floor consists of a movable frame, a storage device for the material which is carried by the frame, a first conveyor which runs transversely to the direction of movement of the conveyor and the material from the Receives storage device, a second conveyor for receiving the material from the first conveyor and for transporting the material to the storage device, as well as outlet openings through which the material is to be distributed by the first conveyor _y whereby the first conveyor can be pivoted from an operating position to an inoperative position The device can contain a closing device for closing the outlet openings. In this way, material can escape from the conveyor

BADORiQINAL 809851/1349

prevented while driving and while steering a when there is no need to distribute the material. The device can also contain an adjusting device for adjusting the position of the closing device in order to adjust the size of the outlet openings to change. This feature enables the Material distribution amount can be changed easily.

The distributor also expediently contains one Facility to interrupt the flow of material the storage device to the first conveyor when the first conveyor is swiveled into an inoperative position, and the material flow can be automatic be interrupted when the first conveyor is pivoted to an inoperative position, even if the Unintentional pivoting of the conveyor occurs as a result of an obstacle.

The movable channel preferably includes a main frame that supports the storage device and one Subframe that supports the first and second conveyors and which can be pivoted into an external operating position with respect to the main frame. The first and second Conveyors can be cantilevered from the moving frame.

The first conveyor can be pivoted about a vertical axis into an inoperative position, indder the The conveyor is generally parallel to the direction of movement of the distributor.

909851/1349

The movable frame can be arranged so that ·· it carried by a tractor, and this arrangement can eliminate the need for ground wheels on the distributor remove the distributor for carrying. The whole distributor carried on a tractor is generally more maneuverable than the distributor Tractor shape.

The erate conveyor can be arranged so that ·· he is held in an operating position by a releasable ArretiervoDichtung, wherein the locking device is designed in the form of a resilient stop. In this way, the first conveyor can be moved into an inoperative position when the conveyor is against a meets an obstacle away from the swaying axis.

The conveying capacity of the second conveyor can be at least equal to the conveying capacity of the first conveyor be. In this way the conveyors can be operated continuously even if the outlet openings' are closed and the first conveyor can be loaded with material before the start of material distribution will. In addition, the conveyor drives can even operated continuously during the control process when distribution is not required, eliminating the need to stop and start the Conveyor drive is avoided.

The provision of a circulating material handling system enables regular replenishment of the Conveyor is created over the entire length of the conveyor, as long as the amount of material is replenished

909851/1349

the conveyor, the amount discharged from the conveyor and the capacities of the second conveyor are suitably matched to one another. When the capacity of the first Conveyor is larger than the exit line thus the outlet openings over the length of the conveyor from the same amount of material, and the excess material is returned from the second conveyor to the storage device.

The apparatus includes a transit station at the end of the first remote from the storage device Conveyor through which the material passes from the first conveyor to the second conveyor.

The second conveyor can be inclined upwardly from the transit station to the upper part of the storage device.

A strut attached to the movable frame can be connected to the outer ends of the first and second conveyors and directed so that they the Angle between the conveyors halved.

The second conveyor can override the first conveyor a drive transmission are driven, which in the transit station is located

The closing device for the outlet openings can contain a pusher which is axially displaceable to the first conveyor * and the pusher can be of a Sliding device can be operated via a lever.

Near the upper hinge bracket 49, the tubes 48 are one each frame 25 or 26 is attached to an upright bracket 55, which can also be seen in FIG the upper end of the corresponding second conduit 42 carries · To prevent fertilizer leaking from the unloading stations 47 from being spilled

909851/1 349

Each bracket 55 also has a funnel 5 & > to ensure that the fertilizer falls into the corresponding container 21 or 22 «Each pair of pipes 48 is also welded to brackets 57 and 58, which are respectively attached to the first line 4T and the second line 42 are fastened and is additionally welded to clamping brackets 59 , which are connected to the corresponding through-containers 43 by means of a pair of struts 60.

The augers 45 and 46 are driven by the tractor power take-off shaft screwed to an energy input flange 61 carried by a support 62 screwed to the beam 27 and ^{carrying a 90 o} angular drive gear that has a transverse shaft and drives a double W-roller 63 as seen in Figures 1-3. Each V-groove of the pulley 63 drives a separate belt 64 which revolves around a corresponding aligned drive pulley 65 which, as shown in Fig. 8, is connected by a key 67 to drive a stub shaft 66 for driving a stub shaft 66. The stub shaft $ 6 is supported a cover 69 of a sealed lubricant ball bearing 68 which is supported by not shown wing screws, which cooperate with not shown pin screws that pass through tabs 70 (Fig. 12 and 13) in an end plate 71 which is welded to the sheet metal container 53. The ball bearing 68 is arranged axially in the cover 69 by means of a snap ring 72,

smolder.

and the stub shaft 66 is axially arranged by means of an integral shoulder which rests against one side of the inner race of the ball bearing 68 and by means of a snap ring 73 which locates the drive roller 65 against the other side of the inner race of the ball bearing 68 via an intermediate ring 74 * A neoprene sealing ring 75 cooperates with the cover 69, among other things, to prevent fertilizer from the container from contaminating the ball bearing 68; the Stunel shaft 66 is on a tubular core 76 of the worm 45 for days

At the opposite end of the worm. 45 is. the core 76 is welded to a pin 77 with a ge lap-shaped tip, which has a forked end and which is stuck in a bore formed in the hub of a bevel gear; the drive connection is a diametrical pin 79 which is fastened to the hub of the bevel gear 78 and which engages in the fork-shaped end of the pin 77. The bevel gear 78 meshes with a corresponding bevel gear 8O ₉ which has fewer teeth and which drives a tubular core 81 of the worm 46 by means of a diametrical pin 82 which is attached to the hub of the bevel gear 80 and which drives into the fork-shaped end of a pin 83 bullet-shaped tip engages, which is welded to the tubular core 81. In this way, the bevel gears 78 and 80 form a drive transmission device in the form of a gear ratio countershaft, whereby

the screw 46 is driven faster than the screw 45 »tu * ensure that the passage housing 43 is not clogged by the build-up of excess fertilizer from the first line 4l is delivered. The bevel gears 78 and 80 are made made of nylon and require no lubrication and are supported by metal bolts 84 in a manner to be described later on from a mounting plate 85 which is welded to the through housing 43 using nylon washers 86 and neoprene sealing rings 87.

The upper end of the screw 46 is carried by a Stumael shaft 88 which is attached to the tubular core 81 is welded on, as shown in FIG. 7, and in a sealed lubricant ball bearing 89 is mounted, which is attached to a cover 90 by means of a snap ring 91 wears a neoprene sealing ring 92 to prevent that the fertilizer contaminates the ball bearing 89, and is arranged axially by means of a snap ring 93. The cover 90 is detachable on the bracket 55 by means of a pair of studs 94 and by means of these cooperating wing screws 95 attached.

The first and second conduits 4i and 42 are preferably made from extruded polyethylene tubing. The one shown in Figure 7 is the top end the second line 42 is arranged in a short metal tube which is welded to the bracket 55; the lower end of the second conduit 42 is the same

909851/1349

Way arranged in a short metal tube 97 which is welded to a surface 98 of the through housing 43. The outermost end of the first line 4i is also in a short metal tube 99 arranged, which is welded to the flange 98 of the through housing 43 and its inner end is arranged in a sheet metal bracket 100 which is welded to an end flange 101 of the container 53 is as shown in Figs. The bracket is arcuate and comprises a part the first line 41, which exceeds 180 of its circumference. It can now be seen that the entire Construction carried by each subframe 25 and 26, only the wing bolts 95 »die hold the cover 90 on the bracket 55, from the wing screws, not shown, which hold the cover 69 on the Hold end plate 71 and held together by the tensile forces in struts 60. The Snails 45 can be removed from their respective first lines 41 together with their lids 69 and their rollers 65 after the wing screws, not shown, holding the lids 69 on the end plates 71 have been removed. In the same way can the snails 46 together with their lids 90 from their respective Second lines 42 are removed after the wing hoods 95 have been removed. The maintenance and cleaning of augers 45 and 46 is accordingly simple; the remaining part of the manifold can be disassembled after the struts 60 by unscrewing their

End flights have been released so that the

909851/1349

Pipes defining the first conduit 4i and the second conduit 42 can be drawn from the remainder of the manifold. Ea is beaohten that the lids 69 and 90 when they are removed _r "enable that its screw 45 or 46 by suitable owned opening in the end plate 71 and the bracket 55 may be removed. This type of construction and the materials used make it easier to maintain the distributor. The bevel gears 78 and 80 are easily accessible when a gear cover 102 is removed and can easily be replaced when the worms 45 and 46 are pulled out sufficiently that they no longer engage with the respective pins 77 and 83. Please note that the screws (not shown) that secure the gear cover ·! 102 on the mounting plate 85 de ». Hold passage housing 43, also extending through a pair of plates 10] J and 104, and arrange and hold these, to which the metal bolts 84 are respectively welded; since the plates 103 and 104 are easily detachable, it will be seen that there can be no difficulty in removing the bevel gears 78 and 80 from their respective metal studs 84.

Apart from the opening that the unloading station 47 limited, the polyethylene pipe that delimits the second line 42 is completely flat, but it is also Löefcar by means of the bracket 58 with the pipes 48 connected.

K The polyethylene pipe, which tfie the first line h ~ \ limited, let releasably by means of the bracket 57 with the tubes 48 and being pierced at its bottom by a regular series of equally spaced opening 105 in the figures and 5 can be seen is. An axially displaceable screen 16 is displaceable on the underside of the line 41 and is designed in cross section as shown in FIG. 5 in order to seal off the line 4t tightly. The transverse curvature of the

k aperture 106 also effects a reasonable degree of longitudinal stiffness and there are only a few in the axial Spaced bracket 107 used, which consist of a pair of sheet metal strips 108, which together on a Screw clamp connection 109 are attached to one another and their lower ends by means of respective screws. 110 are attached to a nylon block 111, which the Orifice 106 presses sealingly against the line 4i and with lateral 'lips 112 of the aperture 106 for the purpose the arrangement cooperates. Each strip 108 has elevations 113 »which fit into a corresponding recess 113 »Intervene in line 41 to get a precise arrangement of each strip 108

f put.

After the transition point of the line 41 to the container 53 is the series of openings 105 as openings 114 in FIG continued down the bottom of the container as in the figures 8 and 13 is shown. The aperture 106 has a row of evenly spaced openings 115 » as shown in Fig. 13, which extends over the full

9 0 9 8 5 1/13 4 9

composite lengths of the container 53 and the first Line 4i extend so that each opening 115 coincides with a corresponding opening 105 in the first line * H or an opening 1iA in the container 53 can be brought to the ceiling. A couple Extension springs 1i6 shown in Fig. 11 act between the flaps 112 of the bezel 106 and the hinge bracket 50, around the inner end of the bezel 106 in to draw the position where all openings are $ 10 and open. As shown in Figures 4 and 6, the outer end of the screen 106 is connected by means of an arm 117 to a unit mechanism, the includes an unthreaded bushing 118 which is passed through a Welded bracket 119 at the end of arm 117 is attached and along a threaded adjustment pin

120 is displaceable, which cooperates with a nut 121 which is welded to a tab 122 which is seated on the mounting plate 85. On the opposite side of the nut from the socket 118

121 runs "in pivot pin 123 through a diametrical Hole in the adjustment pin 120 to adjust the position of the bush 118. The bracket 119 is by means of a toggle linkage brought into the closed position, which is shown in Fig. 13 and which the Cover 106 pushes against the action of the springs 1i6 into the closed position, the original The size of the opening through the left end of the socket length of the threaded pin 120 is determined. The two Articulated lever linkage 124 are preferably of the

909851/1349

Tractor driver operated using cords attached to eyelets 125) the preset degree the opening can be accessed from the tractor driver's seat using a scale 126 on the through housing 23 and a corresponding pointer 127 can be estimated, the position of which depends on the respective setting of the socket 118 depends.

Although the openings 105 in the first conduit 41 and the openings 1 ^ k in the container 53 together with the

W. Openings 115 in the bezel 106 cooperate to

Outlet openings with variable cross-section to limit through which the fertilizer flows onto the soil in a controlled amount, the actual distribution of the fertilizer on the soil depends on the height of the openings 115 above the ground, the transverse spacing of the openings 115 and the angle of divergence of the falling fertilizer. In the illustrated manifold, each opening 115 stores a particular strip of fertilizer along the ground. away. Accordingly, the distributor supports parallel rows the same strip of fertilizer on the ground, over which the distributor is moved. Each strip of fertilizer is substantially uniform along its length and is consistent with the other strips of fertilizer comparable. For all practical purposes, however, the strip-like layer deposited by the manifold is essentially uniform provided that the spacing of the individual strips is not is too big * Gaps of up to 15.24 cm (6 inches)

909851/1349

are feasible, as experiments have shown, so that a crop is affected by the fertilizer placed at a distance of 15> 24 cm (6 inches) is »Nonetheless, the actual distance between the outlet openings should be formed to be suitable for the intended use and any suitable spacing of the Openings 105 and 114 can be between 2.24 cm (1 inch) up to 15.24 ent (6 inches) can be used. If desired, larger distances of up to 71 cm (28 in.) Or 6 cm (30 in.) Between openings used for special purposes. However, it should be noted that the minimum distance to the transverse dimensions of the openings T05 and 1i4 due to the function of the aperture 106 is related. Another way to get the distance between to decrease the streak consists in adding two or more staggered rows of openings 115 in the bezel 106 to train.

The two circulating material transport systems 23 and are usually held in the position shown in FIG. T by means of respective locking levers 128, which can best be seen in FIGS . Each locking lever 128 is connected to a horizontal joint 129 with a shoulder of the corresponding bracket 29 and is pressed down by an end position tension spring 130 which is between a pin 131 on the lever 128 and a pin 132 which is attached to the bracket 29, so that another lever 128 arranged stop 133 locking onto a stop

attacks, which is limited by the surface of the bracket 57. If, however, one of the levers 128 is moved upwards, the stop 133 is released from the stop 134 and is held in the released position by the end position spring 130, so that the corresponding subframe 25 or 26 together with the associated circulating material transport system 23 or 24 can be swung about the corresponding axes XX or YY into an inoperative position, which lies longitudinally behind the frame. The oscillating movement can be achieved by manual actuation of the lever 128, for example when the distributor is pulled along the road or through a gate or when one of the augers 45 is to be pulled out; it can also be reached »if one of the lines 41 ttn hits an obstacle; the impact of a collision causes the inclined surfaces of the stops 133 and 13 ^ * * to work together "to expose the part in question and minimize damage". The position of the lever 128 between the tubes 48 in its locking position prevents it from being accidentally actuated will. It should be noted that as soon as a part has swung into the towing position, the corresponding drive belt j4 is slackened in order to interrupt the drive «

¥ ie shown in Fig. 11, the container 53 is im placed in the immediate vicinity of the container 21 in order to take up a constant amount of e-ingredients! However, when a part is swung into the towing position

-i -: 1 P ■ ■: ■ r,

is, the corresponding container 53 is moved away from the bottom of its container 21 or 22 and the remaining contents of the container 21 or 22 could be lost. Accordingly, as shown in FIG. 9, the locking levers 128 are provided with a slot 135 which cooperates with a pin 1j6 belonging to an interrupting device between the container 21 or 22 and the corresponding container 53. This interruption device is in the form of a slide 137 shown in FIG. 11 and which has lips 138 which are carried by longitudinal guides 139 which are fastened to the bottom of the container 21 by means of rivets IkO. The slide 137 runs through a small operating clearance between the bottom of the container 21 and the flanges 141 at the top of the container 53 and has a series of openings 142 which are aligned with corresponding openings 143 when the locking lever 128 is in its closed position. However, as soon as the locking lever 128 is moved enough to release its stop 133 from the corresponding stop 134, the slot 135 actuates the pin 136 for the slide 137 to close the openings 1 ^ 3 in the bottom of the container 21 and the loss of fertilizer when this part is swung into the out of service division.

Another construction for the outer end of one each agitating material handling system is shown in FIG shown, from which it can be seen that the first and second lines 4i and 42 are in a substantially

Cross union vertical plane before reaching the through housing 43. In this way, the excess fertilizer that reaches the transit station 43 falls, on the screw 46 and is transported up to the second line 42. This arrangement avoids any contamination of the fertilizer in the passage housing 43 «Although the fertilizer discharge device not shown, it is the same as that already described and extends extending over the entire length of the first conduit 41 and further along the underside of the passage housing 43f due to the arrangement of the lines 4i and 42 is unbalanced. Instead of the gears 78 and 80 is a pair of U-shaped rollers 178 and ISO by means of a V-shaped belt 181 which runs over a pair of guide rollers 182, used to carry a Adaptation to the inclinations of the screws 45 and reach 46. Have roles 178 and I80 different diameters, so that the worm is driven faster than the worm 45 and are held by respective bolts 84 welded to a single plate I83, the on the mounting plate 85 by means of not shown Bolt is attached, which also holds the belt cover.
