Description

[0001] Innovation in Mechanical Pulverizer Attachments with Fixed Lower Jaw

[0002] Technical Field

[0003] The invention relates to a pulverizer, specifically used for breaking solid materials such as stone, concrete, and brick into smaller particles.

[0004] Background of the Invention

[0005] Pulverization refers to the process of breaking solid materials, such as stone, concrete, and brick, into smaller particles. The equipment used for this pulverization process is commonly referred to as pulverizers or concrete crushers. In the current technique, there are two types of mechanical pulverizers: those with a fixed lower jaw and those with a movable lower jaw. In mechanical pulverizers with a fixed lower jaw, the lower jaw is secured to the excavator arm using an additional connection bracket. This fastening process is typically performed by welding.

[0006] During the welding process, the high heat input on the excavator arm can lead to localized strength losses and potential defects, such as cracks, which are costly to repair and may arise from workmanship errors. Moreover, the use of welded connections requires additional labor, time, and costs.

[0007] The welded connection bracket cannot be easily removed when it is no longer needed. If a different attachment is required on the excavator, the welded connection bracket belonging to the mechanical pulverizer must remain on the excavator arm. The bracket can only be removed by cutting, which can cause damage and leave scars on the excavator arm, leading to significant harm.

[0008] In the current technique, the American patent document US2014319254 describes a demolition machine. In this machine, the lower jaw is secured beneath the excavator arm using an additional part and process.

[0009] Similarly, the American patent document US8464972 describes a concrete crusher. In this concrete crusher, both the upper and lower jaws are movable. The lower jaw is also secured beneath the excavator arm using an additional part and process. Purpose of Invention

[0010] The objective of the invention is to develop a pulverizer in which the lower jaw can be secured to the excavator arm without requiring additional processes such as welding.

[0011] Another objective of the invention is to develop a pulverizer that can be easily assembled and disassembled.

[0012] A further objective of the invention is to provide a pulverizer that prevents localized strength reductions on the excavator arm caused by welding processes.

[0013] Another objective of the invention is to develop a pulverizer structure that can be easily removed without requiring cutting or similar processes when the pulverizer is not needed on the excavator arm, as no additional parts are used for fastening. Yet another objective of the invention is to develop a pulverizer in which the opening of the lower jaw can be adjusted.

[0014] To achieve these objectives, the developed pulverizer includes at least one connection arm (40) that prevents the movement of the lower jaw (12) and adjusts the opening angle. The lower jaw (12) is connected to the connection arm fastening hole (72) on the excavator arm (70) to secure the lower jaw (12) without requiring welding, ensuring its stability and adjustability.

[0074] Detailed Explanation of the Invention

[0075] B The invention relates to pulverizers (10), which are specifically used for breaking solid materials such as stone, concrete, and brick into smaller particles. The pulverizer (10) subject to the invention generally consists of a fixed lower jaw (12) and a movable upper jaw (11). The lower jaw (12) and the upper jaw (11) are equipped with teeth (11.3, 12.3) necessary for crushing and fragmenting the material. The force required for the operation of the pulverizer (10) is provided by the hydraulic cylinder (80) located on the excavator arm (70).

[0076] The lower jaw (12) and the upper jaw (11) are attached to the excavator arm (70) via a center pin (20). This connection is achieved by passing the center pin (20) through the center pin hole (11.4) on the upper jaw (11), the pin hole (12.1) on the lower jaw (12), and the center pin fastening hole (71) on the excavator arm (70). This ensures that the upper jaw (11) and the lower jaw (12) are securely fixed to the excavator arm (70).

[0077] The center pin (20) has a bolt hole (23) on it. A bolt (21) is passed through the bolt hole (23) on the center pin (20) and the bolt hole (12.2) on the lower jaw (12). Once the bolt (21) is in place, a nut (22) is used to secure it and prevent it from coming loose.

[0078] The lower jaw (12) is fixed to the excavator arm (70) via a connection arm (40), preventing the movement of the lower jaw (12). The connection between the connection arm (40) and the lower jaw (12) is established through the connection arm fastening hole (12.4) using an adjustment pin (30).

[0079] In the system subject to the invention, there are two connection arms (40) located on the right and left sides of the excavator arm (70). The connection arms (40) are connected at the top to each other, the side connections (90), and the excavator arm (70) via an upper connection pin (50). At the bottom, they are connected to each other and to the lower jaw (12) via an adjustment pin (30).

[0080] The adjustment pin (30) is passed through the connection arms (40) and the connection arm fastening hole (12.4). After the insertion, the adjustment pin (30) is secured using a washer (31), a nut (32), and a fastening wire (33) to prevent it from coming loose. The connection arm fastening holes (12.4) are located on protrusions (12.5) at the lower part of the lower jaw (12).

[0081] The connection arm (40) includes adjustment holes (41) and a connection pin hole (42). The adjustment holes (41) consist of a first adjustment hole (41.1) and a second adjustment hole (41.2). These adjustment holes (41) determine the opening angle of the lower jaw (12). The connection pin hole (42) is used to secure the connection arm (40) to the connection arm fastening hole (72) on the excavator arm.

[0082] In an alternative embodiment of the invention, the number of connection pin holes (42) can be increased as needed or desired. This allows the adjustment of the lower jaw (12) to be made either via the lower jaw itself or via the connection arm fastening hole (72) on the excavator arm (70).

[0083] When the lower jaw (12) is fixed using the first adjustment hole (41.1), it is in a more open position compared to being fixed using the second adjustment hole (41.2). The number of adjustment holes (41) can be increased or decreased depending on the requirements. In alternative embodiments of the invention, a single adjustment hole (41) can be used, or three or more adjustment holes (41) can be implemented.

[0084] On the inner lower part of the lower jaw (12), connection arm fastening holes (12.4) are located. These fastening holes (12.4) enable the lower jaw (12) to be secured to the connection arm (40). The fastening is achieved using the adjustment pin (30). In alternative embodiments of the invention, the connection arm (40) can be connected to the lower jaw (12) from the outer lower side or without using the protrusion (12.5). The adjustment pin (30) passes through the adjustment hole (41) on the connection arm (40) and the connection arm fastening hole (12.4) on the lower jaw (12). After insertion, the adjustment pin (30) is secured using a washer (31), a nut (32), and a fastening wire (33) to ensure it remains in place.

[0085] The upper end of the excavator arm (70) houses the upper jaw (11). The upper jaw (11) is connected to the excavator arm (70) through the center pin (20) using the center pin hole (11.4) and the center pin fastening hole (71).

[0086] The upper jaw (11) is a movable component, unlike the lower jaw (12). This movement is achieved through the push-pull force generated by hydraulic pressure in the cylinder (80). The cylinder (80) transfers the push-pull force to the rod (83). The rod (83) is connected to the rod connection (130) via the side connection fastening pin (100). The rod connection (130) is further connected to the upper jaw (11) through the rod connection pin hole (131) and the pin hole (11.1). This connection is established using the rod connection pin (60). The rod connection (130) transmits the push-pull force from the rod (83) to the upper jaw (11), imparting rotational motion to the upper jaw (11) around the axis of the center pin fastening hole (71).

[0087] The rod connection pin (60) has a bolt hole (63). A bolt (61) passes through the bolt hole (63) on the rod connection pin (60) and the bolt hole (11.2) on the upper jaw (11). After insertion, the bolt (61) is secured with a nut (62) to prevent it from coming loose.

[0088] The rod connection (130) connects the rod (83) to the upper jaw (11) at the upper end, and to the excavator arm (70) at the lower end. The connection to the excavator arm (70) is established using a side connection (90) and a side connection fastening pin (100).

[0089] There are two side connections (90) located on the right and left sides of the excavator arm (70). The side connections (90) are connected at the top to each other, the rod (83), and the rod connection (130) via the side connection fastening pin (100). At the bottom, they are connected to each other, the connection arm (40), and the connection arm fastening hole (72) via the connection pin (50). The side connections (90) adjust the distance between the rod (83) and cylinder (80) and the excavator arm (70).

[0090] The cylinder (80) is fixed to the excavator arm (70) using a cylinder housing (120) and a cylinder fastening pin (110). The cylinder (80) includes a rod-side oil connection (81) and a piston-side oil connection (82). These connections (81, 82) ensure the supply and discharge of oil necessary for the operation of the cylinder (80). The invention relates to pulverizers, specifically used for breaking solid materials such as stone, concrete, and brick into smaller particles, and is characterized by:

[0091] Enabling the lower jaw (12) to be fixed to the excavator arm (70) without requiring a welding process by connecting the lower jaw (12) to the connection arm fastening hole (72) on the excavator arm (70).

[0092] Preventing the movement of the lower jaw (12) and allowing adjustment of its opening angle through at least one connection arm (40) that includes at least one adjustment hole.
