Description

ENHANCED ADJUSTING MECHANISM FOR PADDLES IN CLEANING CHAMBERS OF PUMPKIN HARVESTING MACHINES

TECHNICAL FIELD

The present invention relates to paddle connected to the inside of two separate cleaning chambers as I and II of pumpkin harvesting machines used in the harvesting process of pumpkin seeds.

In particular, the present invention relates to paddle connected to the inside of two separate cleaning chambers as I and II of pumpkin harvesting machines used in the harvesting process of pumpkin seeds;

- wherein, the paddle comprises an adjusting mechanism that contains tube, pivot, cap, segment, motion nut, multiple paddle arms, spline flange or transmission flange that are contacted with two separate paddles and that performs the adjusting operation of the pressure intensity that will be applied by paddle rubbers positioned on paddle arms to the inner wall of the perforated drum when the user rotates the motion nut and that also allows the adjusting of pressure intensity of paddle rubber that separates the pulp and pumpkin seeds from one another by coming into contact with the inner wall of the perforated drum to be carried out effortlessly and in a short span of time, thus allowing the process of harvesting carried out through the pumpkin harvesting machine to be performed with high efficiency.

STATE OF THE ART

Nowadays, for the production process of pumpkin seeds, pumpkins are planted to agricultural lands for their seeds and harvesting operations are carried out. Pumpkin harvesting machines that does not require man power have been developed for the harvesting operations of pumpkins. In harvesting operations carried out by means of pumpkin harvesting machines, pumpkins ripened on agricultural lands are evenly aligned on the ground. Pursuant to the aligning process, pumpkins are picked up from the ground by means of the spiked ball of the pumpkin harvesting machine and conveyed to the machine's Batur chamber by means of belt conveyor. After pumpkins are crushed inside the Batur chamber, they are transferred to cleaning chamber I and cleaning chamber II respectively. Pumpkin seeds that are cleaned inside cleaning chamber I and cleaning chamber II separately, are then conveyed to seed tank by means of the spiral or grain fan that is connected to the cleaning chamber

Paddles connected inside of perforated drums of cleaning chambers belonging to pumpkin harvesting machines that are used in the state of the art are composed of paddle arms that are fixed on the paddle pivot at certain distances and paddle rubber that is connected to each paddle arm in a dismountable manner. While the cleaning operation is being carried out following the crushing of pumpkins inside the machine, paddle rubbers operating inside the perforated drum discharge the pulp and pumpkin juice out of the holes located on the drum by scraping inner side walls of the perforated drum.

Stated pumpkin harvesting machines are used in the harvesting operations of skinned pumpkins only. The reason is that in the pumpkin harvesting operation carried out by using pumpkin harvesting machine, paddles operating inside of perforated drums of cleaning chamber I and cleaning chamber II of the machine apply a higher intensity of cleaning pressure to different types of skinned pumpkin seeds. Due to the rigidity of paddle operating inside of the perforated drum located in cleaning chambers that are adjusted to seeds of skinned type pumpkins, since seeds coming out of pumpkins without skin are feebler compared to skinned pumpkin seeds, these seeds break which results in yield loss.

Paddle rubbers continuously scraping inner side walls of the perforated drum wear out over time and assume a shape that is curved backwards depending on the direction of rotation. In such a case, since paddle rubber fails to scrape the inner side wall of the perforated drum, an efficient cleaning operation cannot be achieved, and decreased productivity emanates within the machine. For the purpose of eliminating above mentioned problems, patent application bearing the number TR 2016 12742 and title "Adjustable Paddle Used In Cleaning Chambers of Pumpkin Harvesting Machine" has been made in the state of the art by us. In the abstract part of the respective application statements of "The present invention relates to paddles (6) located inside of two different perforated drums (4.1) belonging to the cleaning chamber I (4) and cleaning chamber II (5) of pumpkin harvesting machine (A) used in the process of harvesting of pumpkins that are grown in agricultural lands without utilizing man power, characterized by comprising; a paddle plate (6.2) having a channel (6.2.1) upon and fixed at certain distances and in certain angles around the pivot along the full- length of paddle's (6) pivot (6.1) and adjustment cap (6.3) that performs the distance adjustment in a way that paddle rubbers (6.5) apply pressure to inner side wall of the perforated drum (4.1) by moving on the paddle plate (6.2) in case that paddle rubbers (6.5) wear out, in order to carry out the cleaning via separation process of pumpkin seeds of pumpkins with or without skins in a highly efficient and long-lasting way within the pumpkin harvesting machine (A)."

DETAILED DESCRIPTION OF THE INVENTION

In the harvesting operation of pumpkins that are grown for theirs seeds in agricultural lands without requiring man power pumpkin harvesting machines are utilized.

In harvesting operations carried out by means of pumpkin harvesting machines, pumpkins ripened on agricultural lands are evenly aligned on the ground. Pursuant to the aligning process, pumpkins are picked up from the ground by means of the spiked ball of the pumpkin harvesting machine and conveyed to the machine's Batur chamber by means of belt conveyor. After pumpkins are crushed inside the Batur chamber, they are transferred to cleaning chamber (T) I and II respectively. Pumpkin seeds that are cleaned inside cleaning chamber (T) I and II separately, are then conveyed to seed tank by means of the spiral or grain fan that is connected to the cleaning chamber (T) II.

- tube (100) that comprises multiple running clearances (110) placed at certain distances around and along the tube's full-length and that has auxiliary holes (120) placed in such a way that they will come in between running clearances (110) as it can be seen in Figure 7,

- pivot (200) that is passed through the inner section of the tube (100) and that comprises restriction pin (230) that is connected with assembly holes (220) and towards its front section in such a way that it will be in alignment with running clearances located on the tube (100) along with its full-length and that it will correspond to assembly grooves (210) along with auxiliary holes (120) as it can be seen in Figure 8,

- cap (300) comprising restriction groove (320) that is connected to the tube (100) in such a way that it coincides with the front section of the pivot (200), that has segment groove (310) on the outer front section, and through which the restriction (230) located on pivot (200) passes as it can be seen in Figure 12,

- segment (400) that consists of two parts and that is passed through the segment groove (310) positioned on the cap (300) as it can be seen in Figures 2, 3 and 4,

- motion nut (500) that moves the pivot (200) inside the tube (100) by being fixed to the segment (400) by means of the bolt (510) and that is connected on the pivot (200) through the screw path (240) in a way that it will coincide with the front part of the segment (400) as it can be seen in Figures 2, 3 and 4,

- multiple paddle arms (600) having paddle rubber (640) that comes into contact with the inner wall of the perforated drum and that is connected to each assembly grooves (210) located on the pivot (200) as it can be seen in Figure 10,

- spline flange (700) that is connected to the tube (100) in a way that it will coincide with the rear section of the adjustment mechanism (A) located on the paddle (P) that is positioned inside the cleaning chamber I (T) as it can be seen in Figures 1 and 13, - and transmission flange (800) that is connected to the tube (100) in a way that it will coincide with the rear section of the adjustment mechanism (A) located on the paddle (P) that is positioned inside the cleaning chamber II (T) as it can be seen in Figures 1 and 14.

As it can be seen in Figures 10 and 11 , paddle arm (600) of the adjustment mechanism (A) comprises of;

- vertical plate (610) having assembly holes (220) on the down side, sloping groove (611) on the upper side and sloping outer surface (612) and that is connected to assembly groove (210) that is positioned on the pivot (200) by means of fixing bolts (660) that are engaged to assembly holes (220),

- tee piece (620) that is connected to the vertical plate (610) and that has vertical groove (621), engagement hole (622), sloping inner surface (623) and bolt holes (624) thereon,

Fixing plates (630) that are connected to front and back sections of tee piece (620) by means of fixing bolts (660) and fixing nuts (670),

Paddle rubber (640) that is connected to the upper section of the tee part (620) by means of sheet bar (650), fixing bolts (660) and fixing nuts (670),

- bushings (680) that are engaged to the outer section of fixing bolts (660) that are connected to sloping groove (611) and vertical groove (621) in order to ensure that vertical plate (610) and tee piece (620) function properly with each other.

In the assembly operation of the subject matter invention adjustment mechanism (A), pivot (200) is connected to the front section by means of running the pivot (200) through the tube (100), while cap (300) is connected to the tube (100) in a way that it will run through the pivot (200). Segment (400) is engaged to the segment groove (310) positioned on the front section of the cap (300). Subsequently, motion nut (500) is connected to the front section of the pivot (200) through the screw path (240) and segment (400) is fixed to the motion nut (500) by means of the bolt (510). As a consequence of this operation, once the motion nut (500) is rotated on the pivot (200), while segment (400), cap (300) rotate fixedly, pivot (200) is moved within the tube (100) in a reciprocating manner according to the direction of rotation by means of the screw path (240). Restriction pin (230) that limits the reciprocating motion of the pivot (200) inside the inner section of restriction groove (320) positioned on the cap (300) is connected to the pivot (200).

Spline flange (700) is connected to the tube (100) in a manner that it will coincide with the rear section of the paddle (P) located inside the cleaning chamber I (T). Transmission flange (800) is connected to the tube (100) in such a manner that it will coincide with the rear section of the other paddle (P) located inside the cleaning chamber II (T).

Following the engagement of the tube (100) and the pivot (200), assembly operation of paddle arms (600) to the pivot (200) is performed. Prior to this operation, paddle arms (600) are assembled as shown in Figure 10.

Accordingly, the Tee piece (620) is run through the engagement hole (622) over the vertical plate (610), thereby allowing the sloping inner surface (623) to come into contact with the sloping outer surface (612). Bushing (680) is positioned to the sloping groove (611) and connected to the bolt hole (624) located under the Tee piece (620) by means of the fixing bolt (660). In this operation, fixing bolt (660) passes through the bushing (680) also and it is ensured that it moves smoothly on the sloping surface (611) of the bushing (680).

In order to allow the reciprocating motion of the Tee piece (620) that is being connected to the vertical plate (610) in a vertical manner correctly, two bushings (680) are engaged to the vertical groove (621) and fixing plates (630) are positioned to both front and rear sections of the Tee piece (620). Fixing bolts (660) that are engaged to fixing plates (630) are also engaged to bushings (680) and fixing nut (670) is tightened with fixing bolts (660). Paddle rubber (640) is connected to the upper section of the Tee piece (620) by means of the sheet bar (650), fixing bolts (660) and fixing nuts (670).

Pursuant to the assembly operation of paddle arms (600) as stated, they are initially positioned in the running clearance (110) that is located on the tube (100) for the purpose of engaging to assembly grooves (210) located on the pivot (200). At this stage, assembly holes (220) which are positioned on the lower section of the vertical plate (610) and assembly holes (220) which are positioned on the pivot (200) are aligned. By means of fixing bolts (660) that are passed through auxiliary holes (120) located on the tube (100) which is positioned on the rear section of assembly holes (220), assembling operation of the paddle arm (600) is completed. This aforementioned operation is repeated for the purpose of mounting a paddle arm (600) to each assembly groove (210) located on the pivot (200) and assembling is completed.

The adjustment of pressure intensity to be applied by the paddle rubbers (640) to the inner wall of the perforated drum (T1) during the operation of the pumpkin harvesting machine is performed as it is shown in Figures 5 and 6. In this operation;

In cases where the pressure intensity is desired to be low, motion nut (500) is rotated to right/left according to the direction of rotation as it can be seen in Figure 5. While the motion nut (500) rotates around its own axis on the front section of the cap (300) by means of the segment (400), screw path (240) located between the motion nut (500) and the pivot (200) allows the forward movement of the pivot inside the tube (100), i.e. enables the rearward movement, as a result of this rotating motion. The distance of the movement is allowed to be as much as the contact distance of the restriction pin (230) to the restriction groove (320). Therefore, the bushing (680) located inside the sloping groove (611) forces the Tee piece (620) to move downwards, i.e. towards the tube (100). At this stage, paddle rubber (640) moves away from the perforated drum (T1) and pressure intensity is reduced. In the stated operation, i.e. through the rotating of motion nut (500), all paddle arms (600) are moved synchronously.

In cases where the pressure intensity is desired to be high, motion nut (500) is rotated to right/left according to the direction of rotation as it can be seen in Figure 6. While the motion nut (500) rotates around its own axis on the front section of the cap (300) by means of the segment (400), screw path (240) located between the motion nut (500) and the pivot (200) allows the backward movement of the pivot inside the tube (100), i.e. enables the forward movement, as a result of this rotating motion. The distance of the movement is allowed to be as much as the contact distance of the restriction pin (230) to the restriction groove (320). Therefore, the bushing (680) located inside the sloping groove (611) forces the Tee piece (620) to move upwards, i.e. towards the inner wall of the perforated drum (T1). At this stage, paddle rubber (640) moves closer to the inner wall of the perforated drum (T1) and pressure intensity is increased. In the stated operation, i.e. through the rotating of motion nut (500), all paddle arms (600) are moved synchronously.
