Description

Dosing Unit For Seed Coating Machines Description Technical Area

The invention is about seed coating machines which provide for coating the seeds with various materials, to be able to store them and increase their productivity. The invention is especially about coating material dosing units, which provide for a long term usage by their helix conveyors with shaft bearing structure, and by their single reductors, in seed coating machines.

Current State of the Technique As Known

In today's agricultural practices, before the seeds contact the soil, they are coated with various materials. This brings certain advantages in planting, storing and shipment. This operation can be carried out by manually mixing the coating material with the seeds in containers, and by using auxiliary elements such as rotating drums. With the current technique, machines were developed such as the one in the utility model document numbered 2006/06179 (A01 C 1/06), titled 'Seed coating machine'.

Machines developed by using the known technique include seed weighing cabin, mixing pot, coating material tank and a dosing unit which transfer the coating material to the mixing pot. Generally, in the dosing units, the transfer channel and the helix conveyor in it is connected to the mixing pot at the side. Therefore the helix conveyor moves only on one bearing, resulting in the non-existence of a shaft structure. For this reason, the economic life of the conveyor mentioned is very short, and it requires modification or replacement frequently. As a result, because there is a need for coating material dosing units for seed coating machines, which would have helix conveyors having shaft structure and single reductor with a long economic life, and because the current solutions are not sufficient, there is a requirement for a technical development in the related area. Purpose Of The Invention

The current invention is about a dosing unit which would make up for the above mentioned requirements, which would eliminate all disadvantages and which would bring some additional advantages.

The main purpose of the dosing unit which is the subject of the invention is; thanks to the helix conveyor being positioned on the bearings in the transfer channel, it can be designed as a shaft structure, therefore having a more robust structure. Discharging the dosed material through the transfer channel is made from the area created at its side walls. The connection between the mixing pot and the transfer channel is carried out through the area mentioned, preferably from the top section. Because the helix conveyor is positioned on the bearings at both ends of the transfer channel as a shaft structure, it will not be shaken during running, therefore usage period will be extended. This will cause less maintenance expenses.

Another purpose of the invention is; by using the mixing container which would be created at the bottom of the dosing tank, at the point it is connected to the transfer channel and by using the mixer, the coating material would be quickly sent to the transfer channel. This affects the productivity of the system positively.

Another purpose of the invention is, thanks to the mixer and the helix conveyor being activated by a single reductor from the same propulsion element, energy is saved, and the new structure includes active parts of a small quantity. Active parts of a small quantity means the number of parts that can break would be less, costs would be less.

To achieve the purposes mentioned above in broad terms, a coating material dosing unit is developed, which includes a shaft structured helix conveyor and a single reductor, which enables a long economic life, to be used in seed coating machines which provide for coating the seeds that are fed through the weighing pot, by mixing them in the mixing pot with the materials taken from the dosing pot. The developed dosing unit includes; at least one propulsion element which drives action, at least one transfer channel that is transferring the materials from the dosing pot, at least one transition container which intermediates the materials transfer between the dosing pot and the transfer channel, at least one helix conveyor with shaft which is positioned in the transfer channel and transferring the materials received from the dosing pot in the transfer channel, with a rotating action driven by the force received from the propulsion element, at least one bearing which keeps the helix conveyor in the transfer channel while bearing its action, at least one exit orifice which enables the discharge of the transferred material, created at the side wall of the transfer channel. The structural features and characteristics of the invention and all of its advantages will be better understood with the figures provided below, and with the explanations referring to the figures. Therefore, the evaluation is required to be made considering the figures and detailed explanations.

Detailed Description of the Invention In the seeding machine (10) of the previous technique which is shown as a profile in Figure 1 , similar dosing systems (50) with the one shown as a profile in Figure 2 are used. In these structures mentioned, because the weighing pot (11) is positioned above the mixing pot (13), for the transfer channel (32) in the dosing system (50) which carries the coating material from the dosing pot (12) to the mixing pot (13), the exit orifice (33) created at the end (35) of the transfer channel (32) has to be positioned at the side of the mixing pot (13). Therefore, there is a requirement to use a helix conveyor without shaft (14) as the element providing transfer in the transfer channel (32). And, because there is the exit orifice (33) at the end (35) of the transfer channel (32), any bearing cannot be applied. This causes a decrease in the durability of the helix conveyor without shaft (14), then causing malfunction frequently.

With the invention, a dosing unit (30) is developed to be used in seed coating machines (10), which provides that the seeds fed from the weighing pot (11) are mixed and coated in the mixing pot (13) with the materials taken from the dosing pot (12). In the dosing unit (30) developed, as it is the case with known applications, there is at least one propulsion element (31) driving action, at least one transfer channel (32) providing the transfer of the materials received from the dosing pot (12), and a transition container (39) which intermediates the materials transfer between the dosing pot (12) and the transfer channel (32). The new elements of the invention are; at least one helix conveyor with shaft (43) which is positioned in the transfer channel (32) and transferring the materials received from the dosing pot in the transfer channel (32), with a rotating action driven by the force received from the propulsion element, at least one bearing (36) which keeps the helix conveyor (43) in the transfer channel (32) while bearing its action, and at least one exit orifice (33) which enables the discharge of the transferred material, created at the side wall (34) of the transfer channel (32).

In figures 3,4 and 5 the visuals of the seeding machine (10) including the dosing unit (30) which is the subject of the invention are provided, as overall, profile and front, respectively. Thanks to the exit orifice (33) being created at the side wall (34) of the transfer channel (32), transfer channel (32) can be connected to the mixing pot (13) from top, bottom or side positions, as desired. This brings options and advantages with regards to the design of the seeding machine (10). Additionally, because the end (35) of the transfer channel (32) is vacant, preferably a bearing (36) can be created here, strengthening the helix conveyor (43). This extends the economic life.

Visuals of the dosing unit (30) are shown in Figure 6 as profile, in Figure 7 as exploded. The coating material in the dosing pot (12) in the upper position fills in the transition container (39) with a downward action, by the gravity effect. In the preferred structure, a mixing container (37) is created between the dosing pot (12) and the transition container (39). In this mixing container (37), there is the mixer (41) which facilitates the transfer of the dosed material, by mixing it. In this design, firstly, coating material fills in the mixing container (37), and then, with the action of the mixer (41), is quickly transferred to the transition container (39). Transfer channel (32) and the transition container (39) are connected to each other, and the coating material entering the transition container (39) directly flows to the transfer channel (32). Throughout the transfer channel (32), helix conveyor with shaft (43) which is rotating with the propulsion received from the propulsion element (31) transfers the coating material first to the exit orifice (33), then to the mixing pot (13). The bearing at the end (35) of the transfer channel (32) enables the helix conveyor with shaft (43) to rotate freely, and prevents it from diverting from the axis. Assembly plate (42) intermediates the connection of the dosing unit (30) with the surfaces.

In the preferred structure, the reductor (38) which is positioned between the propulsion element (31) and the helix conveyor with shaft (43), includes gears (40) which transfer the action received from the propulsion element (31) to the helix conveyor with shaft (43) and/or mixer (41). This way, with the use of the helix conveyor with shaft (43) and with using a single reductor while adjusting the rotation speed of the mixer (41), costs are decreased, and maintenance expenses are decreased because of using fewer active parts. And the risk of malfunction is decreased as well.
