TECHNICAL AREA

The invention; Square sieve passage cover compression assembly, is developed to keep the passage covers in the passages of the square sieve used in the grain grinding plants closed against the high vibration effect caused by the movement of the sieve.

PREVIOUS TECHNIQUE

Square sieve systems are used in grain mills for sizing the grain. The square sieve provides the classification of the product fed into it through the sieving boxes in different particle sizes. The square sieve moves freely depending on the rotational movement of the weight elements in its center and the sieving process takes place within the sieve passages.

The covers used in the square sieve passages are assembled with insulation so that the fine powder fed into the sieve does not escape. Different types of clamping parts are used for the connection of these covers on the passage body.

The most commonly used compression element in existing square sieve passage covers is usually by means of lugs made of metal material. Since the flat contact surface of the clamping shoe on the sieve passage cover does not stand still during the bolted connection of the shoe to the passage body by the operator, the assembly process is both difficult and the assembly is unhealthy as the desired level of compression cannot be achieved.

BRIEF DESCRIPTION OF THE INVENTION

In order to enable easy and effective assembly of the parts used for the firming of the passage cover in the square sieve passages, the square sieve passage cover compression assembly subjected to the invention has been developed. Thanks to the centering tab (4.1 ) formed on the compression shoe (4) and the pin seating surface (4.2) in the developed square sieve passage cover compression element, the shoe (4) is provided to remain in the desired position during the assembly of the operator. Thus, during the bolted connection of the shoe (4), the torque required to rotate the connection bolt (6) can be easily applied by the operator, and both the assembly time is shortened and the desired level of passage cover mounting tightness is achieved.

DETAILED DESCRIPTION OF THE INVENTION

Square sieve passage cover compression assembly subjected to the invention, developed in order to enable easy and effective assembly of the parts used for firming the passage cover in the square sieve passages; includes parts and sections as the passage cover (3), which is connected on the passage body sheet (2) and contains at least one pin slot (3.1 ) on it for the protection of the inner part of the square sieve passage (1 ) from external effects, at least one centering nail (4.1) on it, compression shoe (4) comprising at least one pin seating surface (4.2) and at least one connection hole (4.3), and at least one centering pin (5) and at least one connection bolt (6).

The passage cover (3) developed in the square sieve passage cover compression assembly subjected to the invention, includes a pin socket (3.1), which provides the connection for the centering pin (5) into which the centering nail (4.1 ) of the compression shoe (4) will be centered inside.

The compression shoe (4) developed in the square sieve passage cover compression assembly of the subject of the invention, includes parts and sections of at least one centering nail (4.1) that provides the centering and fixing of the contact of the shoe (4) to the passage cover (3) by entering into the centering pin (5) connected in the passage cover (3) pin slot (3.1 ), at least one pin seating surface (4.2) providing a large contact surface area with the centering pin (5) head part, and at least one connection hole (4.3) that enables the connection of the shoe (4) to the connection hole (2.1 ) located on the passage body sheet (2) with a bolted connection.

The centering tab (4.1 ) developed in the square sieve passage cover compression assembly of the subject of the invention is the section manufactured in such a way that it protrudes from the body on the compression shoe (4).

The centering pin (5) developed in the square sieve passage cover compression assembly of the subject of the invention is a part with a hollow structure that provides centering within the centering nail (4.1 ) located on the compression shoe (4) by connecting within the pin slot (3.1 ) formed on the passage cover (3).

The compression lug (4) developed in the square sieve passage cover compression assembly of the subject of the invention is connected to the passage body sheet (2) via the connection hole (2.1 ) by means of the connection bolt (6) passing through the connection hole (4.3) located on it. The position of the clamping shoe (4) is also fixed by the centering nail (4.1 ) located on it passing into the centering pin (5) connected to the pin socket (3.1 ) located on the passage cover (3). During the rotation force applied to the connection bolt (6) for mounting, the centering claw (4.1 ) of the clamping shoe (4) is fixed in the pin (5), so that the shoe (4) remains in a fixed position despite the bolt tightening action. Thus, the operator fixes the clamping shoe (4) for the passage cover (3) without any difficulty. The pin seating surface (4.2) formed on the compression shoe (4), on the other hand, creates a wide contact surface by contacting the head part of the centering pin (5) connected in the pin slot (3.1 ) and thus a high-strength compression is achieved with the bolted mounting of the compression shoe (4).
