Automatic potato planter

The invention relates to an automatic potato planter with grippers arranged on a revolving link chain, which are connected to the between two guide chain wheels go through the ascending strand of the chain through a space of a potato storage container. This bucket is on the one side through this strand of the chain and on the other side from one extending approximately in the vertical direction of the storage container multi-part partition and under this partition from the bottom of the container, which usually runs obliquely to this strand limited.

In this case, this partition wall is formed in the reservoir a Mllraum on the other side and the upper portion of the multi-part dash usually fixed with respect to the reservoir in relation thereto, can jedooh such relative to this stationary part a movable part that is, a 'NaOH below in a fixed position set part leg and takes the lower end of the movable or adjustable Ttile

different distances from the bottom of the container that allow the Passage cross-section between the ladle chamber and the filling chamber of the storage container.

Two solutions are known for the movable mounting of this lower part of the partition at its upper stationary part, Both solutions serve the task by arbitrarily adjustable movement of the lower part of the partition wall relative to the Bottom of the container to set the passage cross-section between its lower end and the container bottom firmly as required and to be determined in the set position, thus depending on the rolling ability of the different strengths of effort of the potatoes in the storage container behind the partition (on the side away from the link chain) into the to penetrate the front, adjacent to the chain space of the storage container, by the arbitrary adjustment of the movable Part of the partition wall can be taken into account.

In one case of the known potato planting machines, this adjustability is through a relative to the stationary part of the Partition wall different to the preferably inclined bottom of the storage container adjustable and in the set Location embodied remaining rigid slide. In another known embodiment, a rigid plate is attached. The lower end of the fixed upper part of the partition wall is hinged and by means of a snap-in hand lever on different Sohwenklagen relative to the sloping bottom of the storage container adjustable and ascertainable in such a way that the different Sohwenklage different Durohtrittsquerschnittβ between

009828/0392

the lower edge of the flap and the sloping bottom of the storage container determine and during the operation of the potato planter determine.

Compared to these known solutions of the general object of the invention the present invention is based on the knowledge that these solutions are primarily therefore insufficient for practice are because they only have a one-time and in any case not automatically changeable setting of the passage cross-section for the access of the potatoes from the rear or filling space of the storage container to the one adjacent to the link chain Allow pumping space and according to the rigid design of adjustable slide and adjustable pivotable Do not do enough to avoid damaging the potatoes pushing in from the back of the storage container permit; Above all, however, it is not sufficient to meet the practical needs of planting potatoes in the direction of travel different slopes or different inclines a constant passage cross-section for the work step for the potatoes flowing into the link chain under the partition wall only once fixed, the same remains e η d to be set. Rather, every significant change in the slope of the terrain in the direction of Rows of potatoes - i.e. continuously - either a new adjustment of the slide or the flap is laborious with one special operator or by dismounting the tractor driver and interruption of the journey is necessary or inconsistent working and planting of the potatoes must be accepted

be taken. When driving down steeply, the rear space of the storage container too many potatoes per unit of time penetrate into the space adjacent to the link chain, there are too high piling up and double occupancy of the grippers as well as damage to the pent-up potatoes caused by the gripper. Conversely, too few potatoes per unit of time came out of the during a steep upward journey rear space of the storage container into the space adjacent to the chain and were individual grippers instead of one Potatoes, not at all occupied, were thus the rows of potatoes Have flaws. A customary assigned to avoid such defects in the assignment of the gripper However, the device for compensating for defects by scanning the gripper often does not work properly and prevents it not that grippers are assigned twice.

They would also be fixed to a specific one in a known manner Passage cross-section for the potato feed Link chain adjusted sliders or flaps then fail or work inadequately when in the adjustment of small potatoes with large rolling capacity has been assumed, and the rolling capacity or the nature of the Potatoes in the back of the storage container changes while it is being emptied. In any case, with the known devices the decrease in the level of the potato supply in the rear space of the storage container does not

automatically "are taken into account, changing from time to time make a new adjustment of the lower part of the partition necessary.

In other words, the basic disadvantage of the known devices with rigid and permanently adjustable lower partition wall part is that there is no automatic control or sealing of the potato flow from the rear part of the storage tank to the chain, which affects all variable influencing factors such as oil capacity, the remaining stock and in particular the variable slope of the terrain would automatically take into account, but only an occasional fixed control with a mere arbitrary assessment of the respective jiinx'iub factors, so that at least temporarily the above - "^ aids when laying out the potatoes come into play.

The finding creates a remedy and solves the task of a e sealing of the potato zuzizoms to the link chain and the task of not only intermittently and insufficiently, but rather, the 'bad conditions' occurring with the known devices to avoid permanently and automatically.

According to the invention, this object is achieved in a device of the type mentioned at the outset in a very simple manner in that a flexible apron bo extending one of these parts is attached to the upper stationary part or a part of the partition wall that can be fixed downwards, so that Bie as a Pfihler on the level of the potatoes in the Sohöpfraum ,

certain green pressure of these potatoes against those from the Lüllraum penetrate through the passage cross-section to the pumping chamber Potatoes appeals and is free as Independent control link on different turns towards the chain according to the inclination of the The area traveled by the machine in the laying direction and the dependent potato level in the scooping area on one The distance between its lower end and the bottom of the container is set at which the inflowing amount of potatoes is always on average is equal to the amount of potatoes conveyed away by the grippers of only one potato per gripper per unit of time.

With this device, instead of the previous fixed one-time setting of a slide or a flap by hand, an automatic, continuously variable setting is achieved which continuously takes into account the different and changeable influencing factors that occur during operation, in particular the slope of the terrain in the direction of travel of the potato machine, by automatically controlling the apron and causes a momentary misadjustment of this actuator until the desired state is reached ; This state is characterized in that each of the grippers is assigned only one single potato, and there is no double assignment or no idling of a gripper to be loaded, and for this purpose the level of the potatoes in the scoop space, the height required for this mode of operation a? has enough or sioh stops, in which the amount of potatoes conveyed away in the aforementioned manner in the unit of time

The device according to the invention can be used for automatic control of the passage cross section between the apron and the bottom of the Yorrat container approximated as a bowler, in which the horizontal projection of the Apron in the scoop chamber a sensor for indirect measurement of the height of the potatoes in the scoop chamber through the one of them pressure exerted on the apron and at the same time, in a more or less bent state, an actuator for the desired Regulation of the passage cross-section between the lower end of the skirt and the bottom of the storage container is, the manipulated variable by the bend or the angle of the lower end of the skirt in relation to the stationary part of the partition and the servomotor through the interaction of the potato pressure in the scoop chamber with the higher counter pressure of the following potatoes in the pull chamber at the passage cross section under the Apron is given ^ in connection with any reset properties the apron.

009828/039?

With this approach, the level of the potatoes in the scoop chamber is the controlled variable, which is changeable due to the disturbance variable - namely change in the slope of the terrain - and is to receive an optimal constant or almost constant setpoint over time due to the automatic control, due to the fact that the Apron as. • ^ actuator determines the variable manipulated variable, namely the passage cross section below the apron. The setting of any downwardly adjustable part of the partition and the speed of rotation of the link chain are to be considered as so-called predetermined, constant or variable control parameters in the control device. By setting such a part of the partition wall, the rolling capacity of the potato quantities accumulated in the two spaces of the storage container, which is different depending on the size and rounding of the potatoes, and the position of the partition wall in the longitudinal direction of the storage container can be taken into account in advance, with § * $ Ii§eie ^are either part of the partition wall serve as a carrier of the skirt or on the side facing the chain side of the skirt, it can be adjacent in a different setting determined ·

In the given overall context, it can be desirable or undesirable Influences from the arrangement, type and material properties of the apron, e.g. any restoring force and / or their flexibility are appropriately taken into account or eliminated in advance.

Construction O 009828/0392

To cover potatoes, i.e. missing parts and double coverings do not enter; because those at the lower grippers of the chain strand 8 potatoes still lying over a gripper fall off again, and the counterpressure of the potatoes 22 on the passage

middle cross-section of height A, which represents a Mi = fe * el value, ranks just enough to keep the inflow pressure of the potatoes 18 penetrating from the filling chamber 12 into the scoop chamber 11 so far, that this inflow in the scoop space 11 just continuously covers the removal of one potato per gripper.

To be on the safe side, there can be one at 24 at the bottom of the apron 21, in addition to the weight of the apron itself, the setting of its approximate extended position shown in FIG support.

The desired state shown in Fig. 1 of a so-called flow equilibrium of the conveyed away from the Schöpfiaum, and the amount of potatoes flowing into it in the unit of time now undesirable if the machine κ.B. merges into sloping terrain or drives into sloping terrain. In er · * eren The level of the potatoes in the scoop space 11 would be too warm increase and the pressure of which the apron 21 from the in fig. X position shown turn right into a position in the the height A of the Durohlaßquereohnittee would decrease until iae called flow would be re-established.

In the wide case shown in FIG. 2, the low level would be Potatoes in Sohöpfraum 11 removed excessively and as shown

009 82 8/0392

The now increased overpressure of the space 12 pushes through and bends Potato. 18 the apron 21 towards the link chain until the height A of the passage cross-section has increased so far that the flow equilibrium mentioned is restored.

A change similar to that of the case of fig. I after the one 2 also occurs, for example, when the container 12 unexpectedly and in contrast to FIG. I after a certain

The setting of the skirt 21 is also dependent on the flexibility and the dioke of the material and its resilience properties or influenced by their weight in the manner already mentioned, and these factors can be selected accordingly as required or largely 'switched off. So, if necessary, at the lower end of the Schttree both according to Fig. 1 and 2 and in the embodiments of FIGS. 3 and 4, what has already been mentioned Additional weight 24 can be attached, or the apron can be made up of several parts, possibly also made of rigid ones attached to one another Links be composed, and these can be made with the help of elastic Rüoketellglieder, e.g. torsion springs, not shown at the joints on her

strive for a stretched hanging position. However, it is in all cases Advantageously, if at least the lower end 24 of the apron is made of flexible and relatively soft material, around the This is to avoid damage to the potatoes that occurs with the known devices, e.g. stripping off their germs.

In the Pig. 3 is made of an apron 21a flexible and preferably elastic Yferkstoff not on Slide 14 »but directly at the lower end 25 of the stationary Part 13 egg partition 10 attached. The difference-

In the embodiment of FIG. 4 is at the lower end of the fixed part 13 of the partition wall 10 at 26 a rigid flap 15 pivotally attached. The pivot position of this flap can As already mentioned, set variably by means of a hand lever 27 and by means of a ratchet lock 17 in the selected V / inclination can be determined.

009828/0392

Similar to after. ig _e 1 and 2, but in U ¹ Ig. 4 not drawn, an apron 21 could be attached to the lower end of the flap, Me gripping D v / i'rae then through the flap and the G-rö.r'e A through the flap 13 and the more or less f / roiie bend of the apron bastLiimt and - regulated by the latter «
