! Locking device for pick-up drums, especially on self-loading wagons for agricultural building forage »

The fire relates to the training and the arrangement the Sasteinrichtung a pick-up! drum or the like. to accommodate Agricultural forage lying on the ground, in particular for the receiving device on agricultural self-loading wagons. Hetierung always refers to one that is as uniform as possible vertical distance of the pick-up drum from the surface of the Floor to achieve a clean and uniform pick-up of the crop from the floor *

It is known that the pick-up drum is evenly spaced from the ground by Sastrader or skids that are coaxially are arranged with the pick-up drum. Sine such arrangement the l'asträder, where the! Easträder and the Piekup-iromiiiel in the same vertical to the longitudinal axis of the pick-up drum parallel levels are effective, offers the advantage an absolutely even working depth for the pick-up sronmel, however, it requires the entire pick to be lengthened up-linearity, because the wheels are outside the working area of the Pick-up drum must be arranged. Are the iasträder to achieve a pick-up drum unit that is not too wide, i.e. including the length of the pick-up drum of the two front wheels, very close arranged at the pick-up iöronffiiel, so the capacity The pick-up drum is lowered by the fact that the load wheels Hold the crop on the ground «For long and tough crops it can easily lead to wrapping or to a

Bending of the prongs of the pick-up frame, causing disruptions in the work flow. If, on the other hand, the seed wheels are arranged farther away from the pick-up drum, then the entire pick-up drum unit is widened in a possibly very disadvantageous manner. In addition, those associated with the pick-up drum run axially 'guide wheels often works too deep in the tractor track, whereby in soft ground conditions, the pick ~ up ~ ^r ürommel. for uniform soil conditions then there is always the possibility by a corresponding Yerstellung the East wheels whose vertical distance from the Pi ck-up "-Ir Ommel can be changed in order to achieve an even, optimal, running motion of the piek-up drum; however, if the soil has an uneven load-bearing capacity on one and the same insert surface, such a compensation is not possible.

Are the asträder other hand, as previously announced, the pick-up - '!' Drum lagging or-even assigned, leading, so the distance between the Piek-up iirommel is off the ground in not entirely flat Qe country very uneven since the 'J-'astrader and the Pick-up-! Erommel operate in two different planes parallel to the longitudinal direction of the Pick-up-Irommel. If the Pmck-iip-ffirommel with trailing wheels, for example under a self-loading wagon, so that it can swing backwards in the vertical plane, the pick-up drum works too deep, "if either the tractor wheels or the running wheels of the self-loading wagon run through a depression in the floor, as the pick-up drum swivels backwards as a result of the reduction in the vertical distance between the piek-up drum and the question frame of the self-loading wagon greater distance from the point of articulation common to both ropes can be raised more than the l-ick-up iromaiel. On the other hand, it increases when the tractor wheels or the over a bump in the ground

Running wheels of the self-loading wagon or the like, the vertical ATd stands between the piek-up drum and the support frame of the self-loading wagon or the like, so the pick-up! Pick-up ^r i! RomHiel trailing fas trader, experienced a greater downward movement than the piek-up drum, causing this to work up. Leading wheels, which are of practically no importance because of the associated risk of winding, show the same effect as described, but in the opposite proportion can be arranged within the pick-up area of the pick-up drum and placed in such a way that they do not run in the tractor track *

The same difficulties inherent in use are also present when skids are arranged instead of Sasträdem.

The control has these disadvantages because the piek-up drum and the (The trader or G-leitkufen in a common Guiding square are arranged, whose Eoppel is expediently a part the! support frame of the. Selbstla.dewagens or the like. is. The change the working depth of the pick-up 2ronmiel can be either by vertically adjusting the 'iiastrader or G-guide runners. . on the rocker arm opposite the paddock or · crying through I-change in length-appropriate to the direction of movement of the recording- ■ Einrichtitag back swing arm with its upper end on the coupling is hinged, can be achieved. Through this novel. The arrangement of the axles or skids becomes the bick-up drum and the! asträder or the like. when using a rectangular G-elbow square raised by the same amount at the same time or lowered so that the distance of the pick-up drum from the ground is always kept constant while by using a

The firing is illustrated in three exemplary embodiments and described in more detail below. Is shows ι Pig. 1 shows the side view of the receiving device with the

Pick-up Iroffliael trailing assigned Sastrsdern, fig. 2 another embodiment in the same view, ! ig. 3 a further embodiment of the inflation.

The cantilever frame 1, for example a self-loading wagon, which is moved in the direction of the arrow A by a pulling force, preferably by a tractor, is provided with two pivot points 2 and 3 for receiving the lateral rockers 4 and 5, 5 * . The - rockers 4 are the iräger for the pick-tip-Irommel 6, which according to the embodiments are assigned the seed wheels 7 trailing. The pick-up drum 6, which is known per se and therefore not shown Ifeise by a chain, a V-belt or the like. is driven to rotate in the direction of the arrow 'is mounted in the lower end of the rocker 4 marked with, these rockers being connected to one another in such a way that they form an inherently rigid support frame for the pick-up drum. The Sas trader 7 are arranged on the rockers 9, which connect the rockers 4 and 5, 5 * with each other, so that they run behind, ie in the working area of the pick-up machine. The rockers "5, 5 ^# are adjustable in length ^ according to the Atis guide sb example lig. 1 and Pig. 2 by a spindle nut 1ο. This can change the distance of the pick-up drum from the ground, on the one hand, and optionally a rectangular barren on the other A trapezoidal G-elbow can be achieved, optionally a rectangular or trapezoidal one

- 5 -

The quadrangle can also be achieved by moving the Swing arm 5 'on the swing arm 9 ″ or 13 and / or by moving it the rocker § "or 13 on the rocker 5 *. To connect the mentioned swing in the respective position are used according to the Guide examples! Ig. 2 and 3 holes or the like, 14 »

! Furthermore, vertical8 bending of the! Rearward index the rocker 9 according to Fig. 1 is basically a trapezoidal one G-elbow square, provided the articulation point for. the Bchwinge on the rocker arm 4 is not arranged higher in the same way is, line offers trapezoidal design of the quadrangle joint the advantage that this means that vertical relative movements can be seen the pick-up 'Iroiimel and the support wheels or the like. be achieved, which in turn offer the advantage when used on uneven floors, that when approaching an elevation through the Aufnähmevorrichtung the pick-up drum is raised more than the Ϊastrader, when approaching a depression, however, is lowered more than the 'Hastrader. This increases the distance between the pick-up drum and the Ground more evenly maintained for 3.1s with parallel guidance by a rectangular joint.

According to FIG. 2, the rockers 9 can also be angle levers, on one leg 12 of which the jockey wheels 7 are articulated and on the other leg 13 of which the rockers 5, 5 ' are articulated. , -. '■

According to Pig. 3 too by vertical adjustment of the feeler wheels or the like on the. Swing arm 9 can be changed, Hach-serve the embodiment to this end, elongated holes 11 arranged in or on the swing arm 9, or other known "guides, in or on which the seed wheels or the like. are fixed but can be adjusted in height »These Adjustment can of course also be added

to the Verstellmögliehkeit according to the 'fig. 1 and 2 intended to be ¹ «

The mode of operation of the implementation of the pick-up drum according to the invention is as follows: As FIGS. 1 and 2 show, the pick-up drum 6 is suspended swinging freely backwards around the articulation point 3. The distance of the pick-up drum 6 from the floor is according to the Pig. 1 and 2 to a fixed pivot point acting by change in length v ^r of the rockers 5, 5 * means ¹ of the spindle nut 1o changed, since extension of the rocker 5, 5 'the rear' End.e the rocker arm 9 bz?, Of the leg 13 Storage of the Sastr & der 7, which is supported against the ground, is pressed downwards and the pick-up drum 6 is raised. When the rocker 5 is shortened, on the other hand, the pick-up drum 6 is lowered »

When changing the vertical distance between coupling 1 and the soil surface, 'for example' when driving through a narrow depression with the tractor wheels or the running wheels 15 of the self-loading agent or the like, inevitably takes place. vertical relative movement of the seed wheels 7 in sighting on the Coupling 1 closed, the pick-up drum 6 being raised with it. When driving over a bump in the ground by the tractor wheels or the running wheels 15 of the self-loading truck or the like. takes place the same process in reverse lease, since here the vertical distance between the Eastwheels 7 and the paddock 1 is enlarged «, ■■

The picked up by the pick-up cargo from the ground'Trommel is in a known per se and therefore not shown manner a IPördervorrichtung, bei8pielsi ^r else a conveyor drum od "like. supplied through which the cargo is conveyed through a loading channel into the loading space of the self-loading truck.

The firing described here can except for a receiving device for self-loading wagons also for other pick-up scaffolding with a piek-up drum or with one conveyor belt, which picks up the load directly from the floor, "The coupling T" is used in the execution shown Examples'! Part of the support frame of the self-loading truck, isf then It is advisable to use a rope from the door frame of the device in question *
