Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, specifically to a quick-release cutting machine with adjustable spacing for arch breaking. Background Technology

[0002] Existing horizontal cutting machines, while capable of both cutting and pushing materials, suffer from drawbacks such as complex equipment structure and large size; long process cycle time and limited efficiency; complex collaborative control; low space utilization; potential material jamming risk; and numerous maintenance points.

[0003] The existing configuration has a cutting effect (or the formation of cutting blind zones) on the side walls of the cutting cavity, the lower corner area where the side walls intersect with the bottom wall, and the upper corner area where the side walls intersect with the top wall (i.e., the peripheral corner area of ​​the cutting cavity).

[0004] In view of this, there is an urgent need for a quick-release cutting machine with adjustable spacing to break up arches, in order to solve the above problems. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-release cutting machine with adjustable spacing for arch breaking includes: a base, the base including a front mounting seat and a rear mounting seat, the front mounting seat being vertically and detachably mounted on the upper front side of the rear mounting seat;

[0008] Two cutting blade sets are horizontally rotatably mounted inside the cavity formed by the rear mounting seat and the front mounting seat. The two cutting blade sets are arranged in parallel. Each cutting blade set includes a drive shaft rotatably mounted inside the rear mounting seat, an adjusting bushing sleeve sleeved on the outside of the drive shaft, and multiple blades equidistantly mounted on the axial outside of the adjusting bushing sleeve.

[0009] The blades of two adjacent cutting blade groups are staggered, and the blades are provided with protruding inward-pushing blade heads;

[0010] A drive component is provided on the rear side of the rear mounting base, and a transmission mechanism is jointly installed between the drive component and multiple drive shafts.

[0011] The transmission mechanism includes a transmission box and two spur gears built into the transmission box. The two spur gears mesh with each other, and the ends of the two transmission shafts extend to the inside of the transmission box and are respectively fixed coaxially with the two spur gears.

[0012] The drive shafts are all connected to the rear mounting base and the front mounting base via spherical roller bearings.

[0013] An oil seal is installed on the drive shaft near the spherical roller bearing.

[0014] A locking nut is threaded onto the outer side of the end of the drive shaft away from the transmission mechanism. The locking nut presses against the blade and adjusting sleeve on the drive shaft, and the locking nut has a thread that rotates in the opposite direction to that of the drive shaft.

[0015] The rear mounting base, at the end furthest from the transmission mechanism, is fitted with a shaft end cap that covers the outside of the locking nut.

[0016] The blade is higher than the top surface of the rear mounting base in the height direction.

[0017] The blade has a toothed cutting edge.

[0018] The blade has a bent cutting edge.

[0019] The blade has a claw-shaped cutting edge.

[0020] The above-described structure of this utility model can achieve the following beneficial effects:

[0021] This solution features three different types of blades, each with a specially shaped design tailored to the material. These blades possess both cutting strength and the ability to generate a directional thrust on the material. The blades are toothed, bent, and claw-shaped. The toothed blade is suitable for handling hard, sticky, and lumpy materials, offering strong cutting power and producing a more granular texture. The bent blade provides excellent balance in cutting and pushing materials; its bending design significantly improves material pushing efficiency, prevents accumulation, and provides a smooth, low-resistance cut, producing uniform block-shaped materials. It is a high-performance blade design overall. The claw-shaped blade has strong gripping, tearing, and active pushing capabilities, specifically designed for handling the most difficult, slippery, or accumulating materials, powerfully crushing and pushing them.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0036] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0037] The following is in conjunction with the appendix Figures 1-12 This application will be described in further detail.

[0038] Example 1: As Figures 1-3As shown, an adjustable quick-release cutting machine with an arch-breaking spacing includes: a base, which is divided into two parts, including a front mounting base 3 and a rear mounting base 4. The front mounting base 3 is vertically and detachably installed on the upper front side of the rear mounting base 4. Specifically, it can be connected by screws for easy disassembly and assembly.

[0039] Two cutting blade sets are horizontally rotatably mounted inside the cavity formed by the rear mounting base 4 and the front mounting base 3. The two cutting blade sets are arranged in parallel. Each cutting blade set includes a drive shaft rotatably mounted inside the rear mounting base 4, an adjusting sleeve 6 detachably sleeved on the outside of the drive shaft, and multiple blades 1 equidistantly mounted on the axial outside of the adjusting sleeve 6 (the multiple blades 1 are coaxially arranged with the adjusting sleeve 6, and the blades 1 and the adjusting sleeve 6 are detachably connected, for example, by screws, so as to facilitate the adjustment of the distance between two adjacent blades 1). The blades 1 of two adjacent cutting blade sets are arranged in parallel. The blades are staggered (the blade 1 is higher than the top surface of the rear mounting base 4 in the height direction). The blade 1 is provided with a protruding inward-deflecting blade head. The rear side of the rear mounting base 4 is provided with a drive component 2 (the drive component 2 can be a conventional model, such as a reducer of model RV75). The drive component 2 and multiple drive shafts are connected by a transmission mechanism 21. Specifically, the transmission mechanism 21 includes a transmission box and two spur gears 5 built into the transmission box. The two spur gears 5 mesh with each other. The ends of the two drive shafts extend to the inside of the transmission box and are coaxially fixed with the two spur gears 5 respectively.

[0040] Based on the above structural configuration, the drive component 2 drives two drive shafts to rotate synchronously in opposite directions through the transmission mechanism 21. The drive shafts drive multiple blades 1 to rotate synchronously, thereby using the protruding inner-pry cutter heads of the multiple blades 1 to pull and convey the material downwards, improving conveying efficiency and breaking arches.

[0041] The drive shafts are connected to the rear mounting base 4 and the front mounting base 3 via spherical roller bearings 8, which makes the drive shaft rotation more stable and smooth and less prone to jamming. An oil seal 7 is installed on the drive shaft near the spherical roller bearing 8 to improve the sealing performance of the spherical roller bearing 8 and play a role in dust protection.

[0042] The drive shaft, away from the transmission mechanism 21, has a locking nut 9 threaded onto its outer side, facilitating quick disassembly and replacement of the blade 1. Specifically, the locking nut 9 is used to press the blade 1 on the drive shaft against the adjusting bushing 6, and the thread between the locking nut 9 and the drive shaft is the opposite of the rotation direction of the drive shaft, ensuring the overall quick insertion convenience and the looseness and stability of the overall structure. The rear mounting base 4, away from the transmission mechanism 21, has a shaft end cap 10 installed on the outside of the locking nut 9, which serves as a dustproof protection.

[0043] In this embodiment, as Figures 4-6As shown, the blade 1 has a toothed cutting edge, which is suitable for processing materials that are hard and sticky, has strong cutting ability, and can produce materials with a more granular texture.

[0044] Example 2: As Figures 7-9 As shown, in this embodiment, the blade 1 has a bent cutting edge. The bent cutting edge has good balance performance in cutting and pushing materials. Its bending design significantly improves the material pushing efficiency, prevents accumulation, and provides smooth cutting with low resistance. It can produce uniform block materials and is a blade disc design with excellent comprehensive performance.

[0045] Example 3: As Figures 10-12 As shown, in this embodiment, the blade 1 has a claw-shaped cutting edge. The claw-shaped cutting edge has strong gripping, tearing and active pushing capabilities. It is designed to handle the most difficult, slippery or accumulating materials and can powerfully crush and push materials.

[0046] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
