Description

Technical Field

[0001] This application relates to the field of concrete block cutting technology, and more specifically, to a concrete block cutting device. Background Technology

[0002] A concrete block cutting device is a piece of equipment used to cut concrete blocks. This device can accurately cut concrete blocks according to specific size requirements, improve production efficiency and product accuracy, and meet the size requirements of concrete blocks for different construction projects.

[0003] The cutting of concrete blocks generates a large amount of dust. Due to the lack of an effective dust collection and treatment mechanism, this dust flies around in the work area, seriously affecting the working environment of the workers and causing great harm to their health. At the same time, the dust also makes the work area messy, which brings great difficulties to the subsequent cleaning and maintenance work. Moreover, traditional cutting devices have deficiencies in ventilation design and cannot effectively prevent dust from adhering to the filter components, resulting in a gradual deterioration of ventilation. Poor ventilation not only makes it difficult to collect dust, but also makes it difficult to dissipate the heat generated during the cutting process. This seriously affects the normal operation and service life of the equipment, increases the maintenance cost and downtime of the equipment, and reduces production efficiency.

[0004] In view of this, we propose a concrete block cutting device. Utility Model Content

[0005] The purpose of this application is to provide a concrete block cutting device that solves the technical problems mentioned in the background art.

[0006] This application provides a concrete block cutting device, including a fixing plate, a fixing frame fixedly connected to the outer wall of the fixing plate, a fixing bracket provided above the inside of the fixing frame, a blade frame fixedly connected to one end of the fixing bracket, an inclined precision filter plate fixedly connected inside the fixing frame, guide nets fixedly connected to both sides of the upper end of the precision filter plate, multiple extension strips fixedly connected to the upper end face of the precision filter plate, a fixing rod fixedly connected to the lower end face of the fixing bracket, a connecting cylinder fixedly connected to the lower end face of the fixing rod, an extension cylinder slidably inserted into the lower end of the connecting cylinder, and a support spring fixedly connected between the connecting cylinder and the extension cylinder.

[0007] Optionally, a hydraulic cylinder is fixedly connected to the end face of the fixed plate away from the fixed frame, and the telescopic end of the hydraulic cylinder is fixedly connected to the fixed frame. A discharge pipe is fixedly inserted into the lower part of the end face of the fixed plate away from the fixed frame.

[0008] Optionally, a slitting blade is rotatably connected inside the blade frame, and a motor is fixedly connected to the side wall of the blade frame.

[0009] Optionally, grid plates are fixedly connected to both sides of the inner wall of the fixed frame, and the two grid plates are in a gap fit. A limit frame is fixedly connected to the lower end face of the grid plate.

[0010] Optionally, a ventilation plate is fixedly connected to the lower part of the fixed frame, and multiple exhaust fan assemblies are fixedly connected to the inside of the ventilation plate.

[0011] Optionally, the outer wall of the connecting cylinder is symmetrically fixedly connected with limiting blocks, and the limiting blocks extend into the interior of the limiting frame.

[0012] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0013] This application utilizes multiple exhaust fan units to draw in dust, allowing the slitting dust to pass through the mesh plate and fall onto the precision filter plate and guide net, effectively preventing dust from flying around. This significantly improves the working environment for staff, reduces the harm of dust to their health, and also makes the work area cleaner, facilitating subsequent cleaning and maintenance. The moving fixed frame drives the connecting cylinder and extension cylinder to move synchronously. The bottom of the extension cylinder moves along the inclined surface of the precision filter plate, and is lifted when passing through multiple extension strips, causing the support spring to contract. After passing, it impacts the precision filter plate under the elastic force of the support spring, thereby causing the precision filter plate to vibrate. This vibration prevents dust from adhering to the holes in the precision filter plate, ensuring continuous and good ventilation. Good ventilation not only helps with dust collection but also reduces the heat generated during the slitting process, playing a positive role in protecting the normal operation and service life of the equipment.

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1-3 This application provides a concrete block cutting device, including a fixing plate 1, a fixing frame 2 fixedly connected to the outer wall of the fixing plate 1, a fixing bracket 4 provided above the inside of the fixing frame 2, a blade frame 5 fixedly connected to one end of the fixing bracket 4, an inclined precision filter plate 9 fixedly connected inside the fixing frame 2, and guide nets 10 fixedly connected to both sides of the upper end of the precision filter plate 9. Dust will move along the inclined surface of the precision filter plate 9 and the guide net 10, and finally concentrate on one side of the precision filter plate 9. This design makes the collection and treatment of dust very convenient, avoids environmental pollution caused by dust falling randomly, and also improves the recycling rate of resources, which is in line with the concept of environmental protection.

[0020] Multiple extension strips 11 are fixedly connected to the upper end face of the precision filter plate 9, and a fixed rod 15 is fixedly connected to the lower end face of the fixed frame 4. A connecting cylinder 16 is fixedly connected to the lower end face of the fixed rod 15, and an extension cylinder 18 is slidably inserted into the lower end of the connecting cylinder 16. A support spring 19 is fixedly connected between the connecting cylinder 16 and the extension cylinder 18. When the fixed frame 4 moves, it drives the connecting cylinder 16 and the extension cylinder 18 to move synchronously. The bottom of the extension cylinder 18 moves along the inclined surface of the precision filter plate 9. When it passes through multiple extension strips 11, it will be lifted, and the support spring 19 will contract. After passing through, it will hit the precision filter plate 9 under the elastic force of the support spring 19, thereby causing the precision filter plate 9 to vibrate. This vibration can prevent dust from adsorbing on the holes of the precision filter plate 9, ensuring a continuous and good ventilation effect. Good ventilation not only helps to collect dust, but also reduces the heat generated during the cutting process, which plays a positive role in protecting the normal operation and service life of the equipment.

[0021] Reference Figure 2 A hydraulic cylinder 3 is fixedly connected to the end face of the fixed plate 1 away from the fixed frame 2, and the telescopic end of the hydraulic cylinder 3 is fixedly connected to the fixed frame 4. A discharge pipe 20 is fixedly inserted into the lower part of the end face of the fixed plate 1 away from the fixed frame 2. A ventilation plate 12 is fixedly connected to the lower part inside the fixed frame 2. Multiple exhaust fan groups 13 are fixedly connected inside the ventilation plate 12. The multiple exhaust fan groups 13 exhaust the dust, allowing the slit dust to pass through the mesh plate 7 and fall onto the precision filter plate 9 and the guide net 10, effectively preventing dust from flying around. This greatly improves the working environment of the staff, reduces the harm of dust to the health of the staff, and also makes the working area cleaner, which is convenient for subsequent cleaning and maintenance.

[0022] Reference Figures 1-3The blade frame 5 is rotatably connected to a cutting blade 6. The side wall of the blade frame 5 is fixedly connected to a motor 14. Both sides of the inner wall of the fixed frame 2 are fixedly connected to a grid plate 7, and the two grid plates 7 are in a gap fit. The lower end face of the grid plate 7 is fixedly connected to a limit frame 8. The outer wall of the connecting cylinder 16 is symmetrically fixedly connected to a limit block 17, and the limit block 17 extends into the interior of the limit frame 8, which plays a good limiting role and makes the connecting cylinder 16 move more stably.

[0023] Working principle: During use, the operator places the concrete blocks to be cut onto the grid plate 7 and adjusts their position. First, the motor 14 is started, which drives the output end to rotate, which in turn drives the cutting blade 6. Multiple exhaust fan groups 13 on the ventilation plate 12 are activated to ventilate the area. During cutting, the hydraulic cylinder 3 is activated, which extends the telescopic end. The movement of the telescopic end moves the fixing frame 4 towards the concrete block. The movement of the fixing frame 4 causes the blade frame 5 and the fixing rod 15 to move synchronously. The movement of the blade frame 5 moves the cutting blade 6 until the cutting blade 6 rotates and cuts the concrete block. During the cutting process, a large amount of dust is generated. The exhaust fan group 13 ventilates the area, and the dust passes through the grid plate 7 and falls onto the precision filter plate 9 and the guide net 10, thus preventing dust from flying around and affecting the operator's operation. The movement of the fixing rod 15 drives the connecting cylinder 16 and the extension cylinder 1... 8. Simultaneous movement: The limiting block 17 on the connecting cylinder 16 moves inside the limiting frame 8. The bottom of the extension cylinder 18 moves along the inclined surface of the precision filter plate 9. While the extension cylinder 18 moves, the support spring 19 retracts. At the same time, the extension cylinder 18 passes through multiple extension strips 11. The extension strips 11 lift the extension cylinder 18, and the support spring 19 retracts. After the extension cylinder 18 passes through the extension strips 11, the support spring 19 rebounds. The extension cylinder 18 will hit the precision filter plate 9 under the elastic force of the support spring 19, thereby causing the precision filter plate 9 to vibrate. This prevents dust from adhering to the holes of the precision filter plate 9 and affecting the ventilation effect. Through continuous vibration, the dust will move along the inclined surface of the precision filter plate 9 and the guide net 10 until the dust moves to the discharge pipe 20. After the concrete blocks are cut, all electrical appliances stop working. The workers take out the concrete blocks, rotate to open the sealing cover on the discharge pipe 20, and collect the dust.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
