Description

Background of the invention

[0001] The invention relates to a dressing device for dressing seed with a dressing chamber in which a dressing agent is to be added to the seed to be fed therein.

[0002] To ensure seed germination with as little loss as possible, it is usually pretreated with protective or preservative agents. For this pretreatment, the seed is fed to a seed dressing device, where it is placed in a dressing chamber. One or more protective or preservative agents, known as seed dressings, are then added to the dressing chamber. The seed is then mixed with the seed dressing, causing it to adhere to the outside of the seed. Such a seed dressing device is known from DE 203 11 120 U1. Underlying task

[0003] The invention is based on the object of creating a dressing device in which even small quantities of seed can be dressed in an advantageous manner, in particular with little manual effort and comparatively low costs. Inventive solution

[0004] This object is achieved according to the invention with a dressing device for dressing seed with a dressing chamber in which a dressing agent is to be added to a seed to be fed there, wherein a plurality of spatially separated dressing chambers are provided and a feed device for the spatially separated feeding of seed to one of the plurality of dressing chambers and a discharge device for the spatially separate discharge of seed from one of the plurality of dressing chambers is provided.

[0005] According to the invention, it is possible to feed seed of the same or different type or variety separately to several dressing chambers and also to remove it separately again. The separation of the respective seed between the dressing chambers is maintained throughout the entire dressing process. This means that even the smallest quantities of seed can be fed, dressed, and then removed in an orderly manner. The allocation of feed and removal is maintained in particular in such a way that the structure of the seed existing before the feed device is also retained after the removal device. The dressed seed therefore has exactly the same structure as the undressed seed when it was previously fed into the dressing device. Advantageous developments of the invention

[0006] In an advantageous development of the invention, the multiple, spatially separated dressing chambers are provided with a blow-out device for blowing the treated seed out of the respective dressing chamber. Using the blow-out device, not only can the seed be blown out of one dressing chamber, but all the dressing chambers can be emptied toward the discharge device. The blow-out device is thus coupled, in particular, to a compressed air supply.

[0007] The multiple, spatially separated dressing chambers are further preferably each designed with a floor surface that slopes downwards toward the discharge device. Seed resting on such a floor surface automatically flows toward the discharge device due to gravity when the dressing chamber is opened.

[0008] The feed device is advantageously designed with a feed coupling for attaching a transfer plate for untreated seed. With the transfer plate, the seed to be fed to the dressing device according to the invention can be prepared in advance in an orderly manner and subsequently introduced into the dressing device with ease.

[0009] Furthermore, the feed device is preferably designed with a feed hose for each dressing chamber for feeding untreated seed to the dressing chamber. The feed hoses thus feed the seed into the dressing chamber in an orderly manner and are at the same time so flexible and compliant that they can easily overcome existing gaps within the dressing device.

[0010] Finally, the feed system is advantageously designed with a common feed opener for all treatment chambers. This feed opener allows for a synchronized and thus structured treatment process, particularly with regard to the treatment and mixing times of seed and treatment agent.

[0011] The discharge device of the dressing device according to the invention is advantageously designed with a discharge coupling for attaching a seed magazine for treated seed. The treated seed can thus be discharged in an orderly manner in the seed magazine according to the invention. The seed magazine is preferably designed to be identical to one of the aforementioned transfer plates, particularly with regard to its external dimensions at its base.

[0012] Furthermore, the discharge device is preferably designed with a discharge hose for each dressing chamber to remove treated seed from the dressing chamber. The discharge hoses thus discharge the seed from the dressing chambers in an orderly manner and are also so flexible and compliant that they can easily overcome existing gaps within the dressing device.

[0013] Furthermore, it is preferred according to the invention that the discharge device be designed with a common discharge opener for all pickling chambers. In particular, in conjunction with the aforementioned feed opener, this creates a clearly defined cycled operation of the pickling device according to the invention.

It shows: Fig. 1 a perspective view of an embodiment of a pickling device according to the invention, Fig. 2 the section 11 - II according to Fig. 1, Fig. 3 a perspective view of an inlet device of the pickling device according to Fig. 1, Fig. 4 the section IV - IV of a transfer plate according to Fig. 5, Fig. 5 a perspective view of a transfer plate of the pickling device according to Fig. 1, Fig. 6 the detail VI of an application device of the pickling device according to Fig. 1. in the open state, Fig. 7 the section VII - VII according to Fig. 6, Fig. 8 the detail VIII according to Fig. 1 and Fig. 9 the view IX according to Fig. 1. Detailed description of the embodiment

[0015] The figures show a pickling device 10 in which a feed device 14, an application device 16 and a discharge device 18 are arranged in a substantially cubic housing structure or a frame 12.

[0016] The feeding device 14 serves to feed untreated seed, usually in the form of a small quantity of individual grains, while the application device 16 serves to apply one or more dressing agents to the seed and the discharge device 18 finally serves to discharge the dressed seed.

[0017] For this purpose, a feed coupling 20 is designed on the upper side of the frame 12 for the feed device 14, onto which a transfer plate 22 is to be placed. For this purpose, untreated seed can be manually fed into the transfer plate 22 or - as is usually the case - from Fig. 10 illustrated seed magazines 50 into the respective transfer plate 22.

[0018] As in the Fig. 4, Fig. 5 and 11, the transfer plate 22 is essentially rectangular in shape and has, within this rectangular shape, several circular-cylindrical plate chambers 24 arranged in rows. On two opposite sides of the rectangular shape, a cover groove 26 is located on the underside of the transfer plate 22, with a cover 28, also rectangular, being inserted into each of these two cover grooves 26. The cover 28 is designed to be large enough to accommodate several transfer plates 22.

[0019] The seed magazines 50 are in their related to Fig. 11 upper area is also provided with two opposite cover grooves 26, so that a cover 28 can also be inserted there over several seed magazines 50.

[0020] At the related to the Fig. 4 and Fig. 5 top page and related to Fig. 11 lower side of the transfer plates 22 there are two mutually opposite cover webs 58 on each side. These cover webs 58 are designed with regard to their external dimensions equal to or similar to the lateral dimensions of the cover 28. In this way, the cover 28, as shown in Fig. 10, from the seed magazines 50 there, which are filled with untreated seed, and instead a transfer plate 22 with its cover webs 58 is pushed onto each of the seed magazines 50. The cover 28 can then be pushed back onto the combination of seed magazines 50 and transfer plates 22. After that, the combination of seed magazines 50, transfer plates 22, and cover 28 can be turned over, whereby the untreated seed from the seed magazines 50 enters the transfer plates 22 and is held there by the cover 28 lying underneath, which acts like a floor.

[0021] The transfer plates 22 filled with untreated seeds are then removed together with the lid 28, as shown in Fig. 1 and Fig. 2, placed on the feed coupling 20. Alternatively, a seed magazine 50 can also be placed there.

[0022] Below the feed coupling 20 is an inlet device 30 with several individual hoppers. By moving the transfer plates 22 on the feed coupling 20 and by retracting the cover 28, untreated seed is transferred from the transfer plates 22 into this inlet device 30. Alternatively, seed can also be fed individually and manually to the inlet device 30. The inlet device 30 further comprises a Fig. 3 invisible, central feed openers.

[0023] Below the inlet device 30 are several inlet hoses 32, through which the untreated seed fed into the inlet device 30 is fed to the applicator 16. The feed hoses 32 carry the untreated seed from above to the applicator 16. This device has a housing 34 in which several dressing chambers 36, in particular six, are arranged side by side in a row. The dressing chambers 36 are essentially circular-cylindrical in shape and have a bottom surface 38 inclined to the horizontal on their downward-facing end face. A dressing agent inlet 40 leads to each of the dressing chambers 36 for selectively introducing one or more dressing agents into the respective dressing chamber 36.A central discharge opener 42 is located to the side of the dressing chambers 36, and a blow-out device 44 is also provided on the dressing chambers 36, so that the finished dressed seed in the dressing chambers 36 can be discharged into the discharge device 18. Furthermore, an associated seed sensor 60 is advantageously located on the application device 16 above each of the dressing chambers 36, by means of which it can be detected whether there is undressed seed in the dressing chamber 36. If this is not the case, no dressing agent is applied to the associated dressing chamber 36, as will be explained below.

[0024] For this purpose, the discharge device 18 has discharge hoses 46, which individually end in front of the dressing chambers 36 and convey the treated seed downwards to a discharge coupling 48. Several seed magazines 50 are then arranged on the discharge coupling 48, which, as mentioned, are designed in their cover area similar to the base area of ​​the transfer plates 22.

[0025] The seed magazines 50, which are already filled with treated seed, can be lifted upwards by means of a lifting device 52, which is arranged in the form of a lift laterally next to the application device 16, so that the filled seed magazines 50 can be advantageously removed from the treatment device 10 by a user of the treatment device 10 and empty seed magazines 50 can also be inserted into the treatment device 10 particularly easily.

[0026] For the aforementioned movement functions on the feed device 14, the application device 16, the inlet device 30, the discharge opener 42, the discharge device 18 and the lifting device 52, actuators 54 are provided, the movement of which is to be controlled by means of an electrical or pneumatic control 56.

[0027] Finally, it should be noted that all features mentioned in the application documents and in particular in the dependent claims, despite the formal reference to one or more specific claims, are to be granted independent protection, even individually or in any combination.
