DETAILED DESCRIPTION OF THE INVENTION

[0084] In this detailed description, preferred embodiments of the twin row seed distributor body group (1) of the invention developed for twin (double row) sowing are described only for the better understanding of the subject in a manner not to pose any limiting effects.

[0085] The invention relates to the innovation carried out in the groups of the seed distributor bodies (1) on the sowing units of the vacuumed-pneumatic based twin sowing machineries used in sowing/planting of fields in the agricultural sector. FIG. 1 and FIG. 2 show groups of twin seed distributor bodies (1) that are the subject matter of the invention and designed to be used in the pneumatic based sowing machineries, and 3-D views of a seed storage and lid (8) in mounted and demounted forms.

[0086] The present invention relates to a novelty in seed distributor body groups (1) on the sowing unit of vacuum precision pneumatic twin sowing machines used in planting on fields in the agricultural industry. 3D assembled and disassembled view of the twin row seed distributor body group (1)developed to be used in pneumatic twin sowing machinesof the invention and seed hopper and seed hopper cover (8) are shown in FIGS. 1 and 2.

[0087] The disassembled view in FIG. 2 shows the shaft bearing assembly (11), motion transmission shaft bearing bushel (12), disc shaft motion gear (13), spring pin (14), seeding disc motion shaft group (15), disc shaft bearing bushel (16), disc motion gear (17), main body inner bearing cover (18), hinged seed discharge gate (20), upper window (right-left) (2.a-2.b), inner seed singulator (right-left) (3.a-3.b), seeding discs (right-left) (4.a-4.b), outer singulator (right-left) (5.a-5.b), rear window (right-left) (6), disc vacuum body covers (right-left) (7.a-7.b), seed hopper container and seed hopper cover (8) provided on the twin row seed distributor body (10).

[0088] FIG. 3 shows one twin row seed distributor body group (1) of the invention, the twin row seed distributor body (10) that enables synchronized sowing on two different sowing rows (double row) at the same time and other mechanism components belonging to the twin row seed distributor body (10) more clearly.

[0089] Accordingly, assembly of the twin row seed distributor body group (1): [0090] Consists of mounting the motion transmission shaft (11.2) of the shaft bearing group (11) enabling the motion of seeding discs (4.a-4.b) on the twin row seed distributor body (10) into the shaft bearing body (11.1) by means of ball bearings (11.3), felt ring (11.4), shim (11.5) and retaining ring (11.6). [0091] The mentioned shaft bearing group (11) is again supported by the shaft bearing bushel (12) and connected with the twin row seed distributor body (10) by means of screws (11.7). [0092] After the mentioned shaft bearing group (11) is connected to the twin row seed distributor body (10), disc shaft motion gear (13) is connected to the part of the motion shaft (11.2) that remains inside the body by means of the spring pin (14). [0093] The seeding discs' motion shaft (15.1) enabling the synchronized movement of seeding discs are connected to the twin row seed distributor body (10) by means of main body inner bearing cover (18), cover connection bolts (19) and disc shaft bearing bushes (16). [0094] Disc motion gear (17) is connected on seeding disc motion shaft (15.1) by means of the wedge (15.5) and gear fixing nut (15.6). [0095] Furthermore, the mentioned seeding disc motion shaft (15.1) is fixed to the twin row seed distributor body (10) by connecting with the disc motion hexagon (15.2), shim (15.3) and the bolt (15.4). [0096] Hinged Seed Discharge Gate (20) is used to easily discharge the seed remaining inside the mentioned seed distributor body (10).

[0097] The operating principle of the twin row seed distributor body group (1) of the invention is described below.

[0098] The basic operation of sowing bodies in pneumatic sowing machines is as follows.

[0099] Vacuum created by an air suction fan of the sowing machine is transferred into one vacuum body cover positioned on the body by means of air suction hoses and air suction vacuum is created for the seed distributor body from one direction. Seeds coming from the seed hopper by this air suction vacuum formed in the seed distributor body adhere to the holes on the seeding discprovided only one for each bodythat operates together with the vacuum body cover. Thus, sowing is performed by enabling seeds to remain on the seeding disc until they reach the sowing components.

[0100] The twin seed distributor body group (1) of the invention is provided with two disc vacuum body covers (7.a-7.b) unlike standard sowing bodies and these covers are simultaneously connected to the cover connection housings on the right and left sides of the seed distributor body (10). Vacuum created by the air suction fan of the sowing machine is respectively transferred to each cover by two different air hoses. Therefore, air suction vacuum inside the twin row seed distributor body (10) required for the twin sowing method is created on both sides of the body simultaneously. Due to the air suction vacuum formed on both sides of the body, seeds going from the seed hopper (8) to the twin row seed distributor body (10) divide into two inside the body, adhere to the holes on two separate seeding discs (4.a-4.b) and remain on these discs (4.a-4.b) until seeds reach the sowing components.

[0101] In twin sowing performed by state of the art seed distributor bodies, seeding discs (4.a-4.b) receive motion from two different motion mechanisms or they receive motion from a single motion mechanism and try to transfer this motion to the other body by means of various systems.

[0102] Unlike its counterparts, in twin row seed distributor body group (1) of the invention, shaft bearing group (11) enabling the movement of seeding discs (4.a-4.b) positioned on one twin row seed distributor body (10) transmits the motion it receives from the motion mechanism to the seeding disc motion shaft (15.1) on which wedge (15.5), gear fixing nut (15.6) and disc motion gear (17) is connected. Disc motion shaft provides motion to two different seeding discs (4.a-4.b) and enables seeding discs (4.a-4.b) to run in synchronism without any extra connection components in between.

[0103] Essential components of the mechanism that enables twin seed sowing by one seed distributor body of the twin row seed distributor body group (1) are; one twin row seed distributor body (10) and shaft bearing group (11) connected on this body (10) by means of bolts, gears transmitting motion (13-17), disc motion shaft group (15) from which seed spreading disc receives motion, bushes (12-16) that enable bearing the motion transmission shaft (11.2) and disc motion shaft group (15) and main body inner bearing cover (18). Covers (7.a-7.b) manufactured in the form of a disc are mounted on side surfaces of the twin row seed distributor body (10) in a folding (can be opened and closed) manner. Seeding disc(4.a-4.b) are mounted on both sides of the body (10) in a detachable manner.

[0104] In a preferred embodiment of the invention, spacing between two discs (distance A in FIG. 6) of twin row seed distributor body (10) can be adjusted to any desired distance and automatically controlled by a button by changing the dimensions of twin row seed distributor body (10) to a telescopic mechanism.

[0105] In a preferred embodiment of the invention, spacing (distance A in FIG. 6) between two seeding disc(4.a-4.b) can be adjusted by a spring mechanism.

[0106] In a preferred embodiment of the invention, twin row seed distributor body (10) can be manufactured in two pieces and combined by means of various fasteners in order to obtain one seed distributor body.

[0107] In a preferred embodiment of the invention, shaft bearing group (11) can be supported by bushes without using ball bearing (11.3).

[0108] In a preferred embodiment of the invention, seeding disc motion shaft group (15) can be manufactured in one piece.

[0109] In a preferred embodiment of the invention, besides air suction vacuum formed on both sides of the body, due to the air blowing system also formed on both sides of the body, seeds going from the seed hopper to the seed distributor body divide into two inside the body, adhere to the holes on two separate seeding disc and remain on these discs (4.a-4.b) until seeds reach the sowing components.

[0110] The seeds coming from the seed storage and its lid (8) to the twin seed distributor bodies (10) by means of the air-suction vacuum designed on both parts of the body are split in half within the body. Afterwards, it is allowed the seeds to stay on the seed distributor discs (4a-4b) through sticking to holes on the separate two seed distributor discs (4a-4b) until the seeds reach the sower member. Functions of the inner trigger (3a-3b) and the outer trigger (5a-5b) here is to perform the process of making, i.e. singling, the seeds that are on the sower seed distributor discs (4a-4b) and stuck into holes single through the seed distributor discs (4a-4b). Thus, it is ensured that a single seed remains on holes of the sower discs (4a-4b) to which dual seeds stuck.
