Description

Technical Field

[0001] This utility model relates to the field of shredder technology, specifically to a detachable and modular shredder fixed blade plate. Background Technology

[0002] A shredder is a machine used for coarse crushing, generally for processing unprocessed raw materials or scraps in the recycling industry, making them smaller in size. Compared with other crushers, it has a lower cutter shaft speed, lower noise, and lower energy consumption.

[0003] Most shredder blades on the market are one-piece designs. Because the blades need to work continuously for a long time, they are prone to wear and dulling and need to be replaced frequently. One-piece blades are also large and heavy, and the space inside the casing is small when installing the whole blade, making it difficult to replace and install. Moreover, replacing the whole blade is costly. Based on years of production experience and customer feedback, since the bottom of the blade is the main wear point during the operation of the shredder, and other parts mainly serve a fixing function, our technical department has improved the shredder blade for easier disassembly and assembly.

[0004] Therefore, we propose a detachable, split-type shredder blade plate. Summary of the Invention

[0005] The purpose of this invention is to provide a detachable, split-type shredder blade plate to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable and split-type shredder fixed blade plate, including a box plate, on the front of which are mounted several evenly arranged fixed blade plate bodies; a replacement component, which is installed below the fixed blade plate bodies and is used to disassemble and replace traditional fixed blade plates; and a disassembly component, which is installed on the right side of the box plate and is used to disassemble and maintain the entire fixed blade plate body.

[0007] Preferably, the replacement component includes a fixed blade head, each fixed blade head is placed in a square groove at the bottom of a fixed blade body that is adapted to it, and two positioning blocks are fixedly connected to the back of each fixed blade head. Each positioning groove is adapted to the size and position of the positioning blocks, and each fixed blade head is connected to the corresponding fixed blade body by screws.

[0008] Preferably, several support brackets are fixedly installed on the lower part of the front side of the box plate, and the contour of the upper surface of each support bracket is adapted to the contour of the bottom surface of the fixed blade plate body.

[0009] Preferably, the front side of the box panel is fixedly connected with a plurality of evenly distributed partition bars.

[0010] Preferably, the disassembly assembly includes three limiting rods that extend from the left side of the box panel to the right side. Each limiting rod is inserted into the fixed blade plate body and the partition rod. The right ends of the three limiting rods are fixedly connected to the same fixing block. A fixing plate is fixedly connected to the right side of the box panel, and two insert rods are engaged on the right side of the fixing plate. The front of the fixing block has two slots, each slot engaging with its corresponding insert rod.

[0011] Preferably, a pull handle is fixedly connected to the right side of the two insertion rods.

[0012] Preferably, two springs are fixedly connected between the pull handle and the side of the fixed plate that is close to it, and the two springs are respectively sleeved with their corresponding plug rods.

[0013] Preferably, the back of the box plate is provided with several slots corresponding to the positions of the fixed blade plate body, and each fixed blade plate body has two slots on its back.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. When the fixed blade of the shredder is damaged, since the bottom of the fixed blade is the main wear point during the operation of the shredder, first remove the entire fixed blade body, including the blade head. Then, loosen the screws on the bottom of the blade head and pull it out to remove the positioning block from the positioning groove. Then, remove the entire blade head and install a new blade head. Finally, reinstall the fixed blade body in its original position to complete the repair of the damaged blade. The matching of the positioning block and the positioning groove can prevent the blade head from being misaligned during installation.

[0016] By setting replacement components, the damaged fixed blade head can be easily disassembled and replaced to complete the repair, without having to replace the entire fixed blade body, which greatly saves costs.

[0017] 2. After replacing the fixed blade head, install the fixed blade body on top of the support frame. The spacers between the fixed blade bodies limit the spacing, and the support frame provides overall support. Next, the operator holds the handle of the fixing block and inserts the limiting rod from the right side of the box panel to the left side. Supported by the three box panels, the fixed blade body is firmly fixed in position. When the fixing block moves to the left, it contacts the inclined surface of the insertion rod. The insertion rod can then be pushed backward. When the insertion rod moves to the slot, it is spring-loaded and engages with the slot. To disassemble the fixed blade body, simply pull the handle backward to remove the insertion rod from the slot, easily removing the three limiting rods.

[0018] By setting up disassembly components, the entire fixed blade plate body can be easily disassembled and replaced, greatly reducing the difficulty of disassembling and assembling the traditional fixed blade plate as a whole, and further improving the overall production efficiency of the device.
