Hauni files 1848 - Hamburg 80, August 2, 1984 device for automatic operation Transferring seeds from a seed supply into a container or to planting areas The invention relates to a device for the automatic transfer of seeds from a seed supply into a container or to planting areas with a circumferential Removal conveyor for conveying away isolated seeds from the seed supply to a Delivery point.

The term "seeds" means seeds of all kinds, which need not have the specific shape of grains.

Under "planting areas" are to be understood the containers or trays, which are filled with seedlings, into which the seeds are introduced should be.

The term "singulation" means the transfer of individual seeds or groups of two or more seeds from a seed supply to understand in a certain order.

For the automatic filling of seeds into individual plant containers is according to EP-OS 001 03 83 a defined number of seeds from one The storage container is simultaneously removed by means of pneumatic suction heads and transferred to the Inlets moved by guide tubes. The seeds are released through the inlets, whereupon they slide down at the same time and after leaving the pipes in the Get to the plant container. The simultaneous suction of a defined number of Seeds from a seed supply is not reliable, so that because of the Feeding several or no seeds in a suction cup results in incorrect inseminations can. In addition, must after Stw .: seeds-isolate-multi-rows-I Hauni files 1848 - Hamburg 80, August 2, 1984 Filing of the series of Seeds in a corresponding row of planters and a new one Row of seeds brought up to the tubes as well as those provided with seeds Row of plant containers conveyed away and a new row of plant containers conveyed in which limits the performance of the known device.

A supply of isolated seeds in a state in which them very quickly and in large quantities while maintaining their order in many Plant containers containing recordings can not be transferred.

To avoid these disadvantages, DE patent application P 34 03 719.5 already proposed a rotating removal conveyor for removal Provide isolated seeds from the supply to a delivery point at the synchronous to the movement of the seeds recordings of a movable relative to the delivery point The semen container can be moved past, each successively with a predetermined Number of seeds are verifiable.

These semen containers have receptacles designed as parallel channels on, which can be subdivided into seed chambers by several sliding shelves are.

The seeds stored in layers and sporadically can if necessary, can be transferred to planting areas while maintaining their order, each layer being freed after an intermediate floor of the seed container is drawn of seeds for the insemination of a planting area, d. H.

a container filled with plants is sufficient.

The invention is based on the task = the performance of a Device for the automatic transfer of seeds from a seed supply in a container or to further increase planting areas.

Stw .: seeds-isolate-multiple-rows-I Hauni-files 1848 - Hamburg 80, August 2, 1984 According to the invention this is achieved in that the removal conveyor is designed as a removal drum, which over the drum width a number of rows of recordings for isolating and extending over the drum circumference Has removal of seeds.

Here, according to the invention, the removal drum is a stripping device assigned to remove excess seeds.

For transferring seeds from a seed supply into a seed container the device according to the invention is designed so that between the delivery point the removal drum and the semen container which can be moved relative to the delivery point for the seeds are arranged.

The number of forwarding elements corresponds to the invention the number of rows of recordings of the removal drum and the seed container.

For transferring seeds from a seed supply to planting areas the device according to the invention is designed so that between the delivery point the removal drum and the planting surfaces movable relative to the delivery point Arranged introducing device for introducing the seeds into the planting areas is.

According to the invention, the introduction device consists of a number of plant thorns and pistons movable in cylinders, each cylinder over a forwarding element for the seeds is connected to the delivery point.

By designing the removal conveyor as a multi-row removal drum the insemination performance of the device was increased without a harmful increase in speed. In addition, the device according to the invention can be used to fill seed containers with isolated seeds, i.e. storing them in storage, also direct insemination of planting areas, e.g. 8. of plant stumps located in trays, too.

Stw .: seeds-isolate-multi-rows-I Hauni-files 1848 - Hamburg 80, August 2, 1984 The invention is to be based on two exemplary embodiments are explained in more detail.

In the drawings: FIG. 1 shows an automatic filling device for a seed container, FIG. 2, the detail "A" according to FIG. 1 in an enlarged manner Representation, Figure 3 shows an automatic locking device for the auxiliary floors in the Seed container in an enlarged view compared to FIG. 1, FIG. 4 the detail "8" according to FIG. 1, which shows the deflector and the blown air nozzle, and FIG. 5 shows another Execution of the automatic filling device according to Figure 1 for direct transfer of seeds from a seed store in plant containers filled with plantlings, Figures the detail "C" according to Figure 4, the 6 and 7 means for introducing the seeds in the plantlings showing in two different positions.

Stw .: seeds-isolate-multiple-rows-I Hauni-files 1848 - Hamburg 80, August 2, 1984 In Figures 1 to 4 is a device for automatic Separating seeds 2 located in a storage container 1 and transferring them of the isolated seeds 2 described in recordings of a seed container 3.

As FIG. 1 shows, a 2 is used to separate seeds revolving removal conveyor 4, which consists essentially of a with receptacles 6 in Form of holes provided removal drum 7 consists of an electrical Drive motor 8 is driven to rotate in the direction of arrow 9. The receptacles 6 are in several rows, which are spaced equally across the width of the drum lie next to each other and each extend over the entire drum circumference, arranged. The interior of the removal drum 7 is in a known manner via a line 11 connected to the suction side of a fan, not shown, which is also is driven by the drive motor 8, so that on the receptacles 6 of the removal drum 7 suction air is present. The removal drum 7 runs through the supply of seeds 2 in the reservoir 1, so that as a result of the suction air at each receptacle 6 a Seed 2 remains adhering and is conveyed to a delivery point 12.

In order to ensure that only one seed 2 is transported per receptacle 6 is, in the direction of rotation of the removal drum 7 after the storage container 1 is a Stripping device 13 extending over the entire drum width is provided, a detail 'BB' of which is shown in FIG.

This stripping device 13 consists of deflectors 14 and blower nozzles 16, with each row of receptacles 6 of the removal drum 7 a deflector 14 and a nozzle 6 are assigned, which with their combined -Abweis- and Blowing effect of the seeds sucked in 6 too much per intake 2 Stw .: Saatgut-isolate-Multireihen-I Hauni files 1848 - Hamburg 80, August 2, 1984 removed and only the seed 2, which is best placed in the receptacle 6, for further transport left.

The blow nozzles 16 are arranged on a common blow air strip 17, which is connected to an air supply 18 by means of a connector 19.

The deflectors 14 are fastened to a bar 21 by means of screws 22. The bar 21 is in turn displaceable and pivotable on a guide rod 23 arranged, so that a precise setting of the deflector 14 to the rows of receptacles the removal drum 7 can perform. The setting is fixed by a screw 24.

The isolated seeds that have now reached the delivery point 12 (FIG. 1) 2 are there by switching off the suction air in this area from the removal drum 7 and fed to the receptacles 27 of the seed container 3 via hoses 26. At the same time, the receptacles 6 released at the delivery point 12 of the removal drum 7 freed of any impurities with the aid of blown air The number the hoses 26 must of course correspond to the number on the removal drum 7 located rows of receptacles, which in turn correspond to the number of longitudinal rows of recordings 27 of the seed container 3 corresponds.

The one at the delivery point 12 according to the row spacing The hoses 26 arranged on the removal drum 7 are in their mouth region 28 in a bar 29 on one of the longitudinal row spacing of the receptacles 27 of the seed container 3 kept a corresponding distance.

FIG. 2 shows the loading of a receptacle 27 as detail “A” of the seed container 3 with a seed 2 Stw .: seeds-isolate-multi-rows-I Hauni file 1848 - Hamburg 80, August 2, 1984 via one held in bar 29 Hose 26.

The semen container 3 (Figures 1 and 2) consists of several superimposed, with receptacles 27 provided plates 31, between which locking elements in the form of Slidable intermediate floors 32 are arranged, and is in the DE patent application P 34 03 719.5 already described in detail.

The seed container 3 is filled in layers from the bottom up to the top plate 31, after filling each plate 31 the overlying Intermediate bottom 32 is inserted. To move the intermediate floors 32 is a automatic displacement device 33 is provided, as can be seen in FIG is.

For filling the seed container 3 in layers, it is necessary that this relative to the transfer point, d. H. for holding the supply hoses 26 Bar 29 can be moved back and forth in the longitudinal direction (FIG. 1).

For this purpose, the semen container 3 is on a table 36 by means of brackets 37 attached. The table 36 is on a table guide 38 in the direction of the double arrow 34 movable to and fro. An electric stepper motor 39 is used for driving The direction of rotation can be switched and its rotary movement is via a spindle drive, consisting of threaded spindle 41 and threaded nut 42, in a translatory movement is converted according to the double arrow 34.

The table guide 38 is attached to a machine stand 43. on the table guide 38 are electrical limit switches 44, 46, which reverse the direction of rotation of Stw.: Seeds-isolate-multi-rows-I Hauni-Act 1848 - Hamburg 80, on August 2, 1984 stepping motor 39 is triggered when the table 36 has reached the end positions reached and thus in each case a plate 31 of the seed container 3 with seeds 2 is filled. At the same time, the drive motor 47 becomes the displacement device 33 controlled and the corresponding intermediate floor 32 inserted so that the through the recordings 27 formed seed chambers of this location are complete.

The steps of the stepping motor 39 are self-evident here the pitch of the recordings 27 adapted. The seeds are also released 2 at the delivery point 12 synchronous with the step movement of the carriage 36 and thus of the semen container 3. The motor 47 for the displacement device 33 is overdriving Gears 48 and 49 connected to the gear 49 multi-groove hub 51, the outside is stored in the camp 52. In the multi-groove hub 51 there is a multi-spline profile 53 in the longitudinal direction movable. The splined profile 53 forms the lower end of a threaded spindle 54, which has no thread in the area of the splined profile 53. The thread begins only above the area in which a relative movement between the multi-groove hub 51 and splined profile 53 takes place. The threaded spindle 54 is fixed by a Threaded nut 56 out and carries an actuating cam 57 at the upper end Roller 58. When activated, the motor 47 executes a rotary movement in which the threaded spindle 54 is raised a distance in the direction of arrow 59, which corresponds to the distance between two adjacent intermediate floors 32. When lifting the threaded spindle 54 rotates so that the actuating cam 57 with roller 58 a Can bring intermediate floor 32 in the closed position. The motor 47 is then deactivated and stays there until the next layer is filled.

St ".: Seeds-isolate-multi-rows-I Hauni-act 1848 - Hamburg 80, August 2, 1984 In this way, with increasing filling of the semen container 3 successively brought all the intermediate floors 32 into the closed position. After reaching the uppermost position and removing the seed container 3 from the table 36 becomes the actuating cam 57 with roller 58 by reversing the polarity of the motor 47 back down into its end position emotional.

The drive for the intermediate floors 32 moves with the table 36. Instead of The mechanical solution shown can also be rapidly electromagnetically controlled Actuators, e.g. B. Magnets or air driven slides, use of one or more can be assigned to each intermediate floor 32. As engines 39, 47 electric or electrohydraulic stepper motors can be used, which can be easily controlled and synchronized using predetermined pulse sequences. With Such motors can also be used to quickly reverse the direction of rotation.

The one in the manner described above with a certain number of seeds 2 filled semen container 3 can be detached from the holders 37 and initially stored until the seeds 2 contained in the | container 3 for the insemination of planting areas, z. B. plant pots, honeycombs in honeycomb trays or plant stumps arranged in containers, are needed.

The insemination of such planting areas from these filled seed containers can in the manner described in DE patent application P 34 03 719.5 with the The device shown there happen and will not be explained again here.
