Description

Technical Field

[0001] This utility model relates to the field of trenching technology, specifically to a multi-drill trenching machine. Background Technology

[0002] Grooving refers to the process of creating grooves on structural surfaces, such as milling grooves in metal or wood. However, milling is not suitable for larger structural materials that require larger grooves. For example, milling cannot be used to create grooves in soil, food or concrete structures, or large wooden surfaces. In such cases, it is necessary to manually cut, dig, or break up the material in the groove bit by bit, from small to large, to finally create the groove. However, this method is inefficient, takes a long time, and affects the overall processing progress. Utility Model Content

[0003] The purpose of this invention is to provide a multi-drill-bit trenching machine to address the aforementioned shortcomings in the prior art.

[0004] This utility model provides the following technical solution: a multi-drill-bit trenching machine, including a frame, a lifting frame at the bottom of the frame, the lifting frame being connected to the frame via a hydraulic cylinder, multiple sleeve drill bits arranged side-by-side at the bottom of the lifting frame, the sleeve drill bits being rotatably connected to the lifting frame, a reciprocating frame at the top of the lifting frame, the reciprocating frame repeatedly moving along the distribution direction of the sleeve drill bits, and sawing plates fixedly connected to both bottom sides of the reciprocating frame via mounting plates, each sawing plate being located on the outer side of the area between two adjacent sleeve drill bits, the lifting frame being equipped with a driver for rotating the sleeve drill bits and moving the sawing plates. In actual use, the frame is positioned outside the desired trenching area, the hydraulic cylinder is controlled to drive the lifting frame downwards, simultaneously controlling the rotation of the sleeve drill bits and repeatedly moving the sawing plates outside the sleeve drill bits. Thus, during the descent of the lifting frame, each sleeve drill bit... Multiple parallel holes are drilled into the material, and the reciprocating motion of the saw blade simultaneously cuts off the uncut solid parts remaining between adjacent holes. The cutting is also performed along the common tangent line of the holes drilled by the adjacent sleeve drill bits, causing this solid material to detach from the connection. Finally, a long groove is formed between this part and the hole drilled by the sleeve drill bit. After this processing is completed, the lifting frame is lifted, and the solid parts cut off by the sleeve drill bit and saw blade are crushed by impact or removed one by one with a small cutting machine. This material can then be removed to form the required groove. If processing is done on soil, the solid parts can be directly removed. If the shape of the groove is strictly required, further processing can be carried out on the groove. Since the basic shape of the groove has already been processed by this equipment, even if subsequent fine processing is carried out, it is convenient for processing machinery to enter, and there is no need to process too much material, which greatly improves the overall efficiency of groove forming and processing.

[0005] Preferably, the driver is a drive motor, which is fixedly installed above the lifting frame. The output shaft of the drive motor is fixedly connected to the rotating shaft of one of the sleeve drill bits, and the rotating shafts between two adjacent sleeve drill bits are connected by a belt drive assembly. Thus, by controlling the rotation of one sleeve drill bit with only one drive motor, all sleeve drill bits can be driven to rotate.

[0006] Preferably, a rectangular frame is fixedly connected to the middle of the reciprocating moving frame, and an eccentric wheel is fixedly connected to the output shaft of the drive motor. The eccentric wheel is eccentrically set with respect to the output shaft of the drive motor and is located inside the rectangular frame. When the drive motor is working, it drives the eccentric wheel to rotate eccentrically, which in turn drives the rectangular frame and the reciprocating moving frame to reciprocate left and right, thereby driving all the sawing plates to reciprocate and cut synchronously.

[0007] Preferably, the bottom of the sawing plate is provided with a serrated edge, and the two sides of the sawing plate are provided with slits, so that the material can be effectively cut when the sawing plate moves back and forth laterally.

[0008] Preferably, the bottom of the frame is fixedly equipped with support legs, and the bottom of the support legs is rotatably equipped with wheels, which facilitates the movement of the equipment during actual work. At the same time, for relatively compact materials or wood, the equipment can be moved forward a certain distance after each drilling and rising of the sleeve drill bit, so that the sleeve drill bit and the saw blade can gradually move forward and cut repeatedly, forming multiple sets of repeated cutting areas in the material, making the remaining solid structure more dispersed and easier to clean. For longer grooves, this method can also be used to gradually increase the length of the groove, thereby greatly improving the adaptability and practicality of the device.

[0009] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0010] This invention controls the rotation of the sleeve drill bit and the repeated movement of the sawing plate outside the sleeve drill bit. During the descent of the lifting frame, each sleeve drill bit drills multiple parallel holes in the material. At the same time, the reciprocating motion of the sawing plate cuts off the uncut solid parts remaining between adjacent holes. After processing, the lifting frame is lifted, and the remaining solid parts in the groove are removed to form the required groove. Compared with the manual operation of drilling holes one by one and then removing the remaining parts, this device greatly improves the overall efficiency of groove forming and processing.

[0011] This invention, by installing wheels on the frame, moves the equipment forward a certain distance after each drilling stroke of the sleeve drill bit. This allows the sleeve drill bit and the saw blade to gradually move forward and repeatedly cut, forming multiple sets of repeated cutting areas in the material. This makes the remaining solid structure more dispersed and easier to clean. For longer grooves, this method can also be used to gradually increase the length of the groove, thereby greatly improving the adaptability and practicality of the device.

[0020] Example

[0021] This utility model provides, for example Figure 1-4The multi-bit trenching machine shown includes a frame 1, a lifting frame 2 at the bottom of the frame 1, the lifting frame 2 being connected to the frame 1 via a hydraulic cylinder 11, multiple sleeve drill bits 3 arranged side-by-side at the bottom of the lifting frame 2, the sleeve drill bits 3 being rotatably connected to the lifting frame 2, a reciprocating moving frame 6 at the top of the lifting frame 2, the reciprocating moving frame 6 repeatedly moving along the distribution direction of the sleeve drill bits 3, and sawing plates 5 fixedly connected to both sides of the bottom of the reciprocating moving frame 6 via mounting plates 51, each sawing plate 5 being located on the outer side of the area between two adjacent sleeve drill bits 3, and the lifting frame 2 being equipped with a mechanism for rotating the sleeve drill bits 3 and for cutting the sawing plates. 5. A drive unit for moving the machine is used. In actual use, the frame 1 is set outside the desired grooving area. The hydraulic cylinder 11 drives the lifting frame 2 to descend, while the sleeve drill bit 3 rotates. The sawing plate 5 moves repeatedly outside the sleeve drill bit 3. During the descent of the lifting frame 2, each sleeve drill bit 3 drills multiple parallel holes in the material. At the same time, the reciprocating motion of the sawing plate 5 cuts off the uncut solid parts remaining between adjacent holes and cuts along the common tangent of the holes drilled by adjacent sleeve drill bits 3. This causes the solid material to detach from the connection and ultimately form a groove between it and the holes drilled by the sleeve drill bit 3. Figure 4 The long groove shown is processed here. After the lifting frame 2 is lifted, the solid parts cut off by the sleeve drill bit 3 and sawing plate 5 are broken by impact or cut off one by one with the help of a small cutting machine. This material can be removed to form the required groove. If it is processed on soil, the solid parts can be directly removed. If the shape of the groove is required to be strict, it can be further processed on the above-mentioned groove. Since the equipment has already processed the general shape of the groove, it is convenient for processing machinery to enter even for subsequent fine processing, and there is no need to process too much material. This greatly improves the overall efficiency of the groove forming process.

[0022] Furthermore, in the above technical solution, the driver is a drive motor 4, which is fixedly installed above the lifting frame 2. The output shaft of the drive motor 4 is fixedly connected to the rotating shaft of one of the sleeve drill bits 3, and the rotating shafts between two adjacent sleeve drill bits 3 are connected by a belt drive assembly 7. Thus, by controlling the rotation of one sleeve drill bit 3 with only one drive motor 4, all sleeve drill bits 3 can be driven to rotate, which greatly improves the processing efficiency of the device.

[0023] Furthermore, in the above technical solution, a rectangular frame 61 is fixedly connected to the middle of the reciprocating moving frame 6, and an eccentric wheel 41 is fixedly connected to the output shaft of the drive motor 4. The eccentric wheel 41 is eccentrically set with the output shaft of the drive motor 4 and is located inside the rectangular frame 61. When the drive motor 4 is working, it drives the eccentric wheel 41 to rotate eccentrically, which drives the rectangular frame 61 and the reciprocating moving frame 6 to produce left and right reciprocating motion, thereby driving all the sawing plates 5 to reciprocate cutting motion synchronously.

[0024] Furthermore, in the above technical solution, the bottom of the sawing plate 5 is provided with a saw tooth 53, and the two sides of the sawing plate 5 are provided with slits 52, so that the material can be effectively cut when the sawing plate 5 moves back and forth.

[0025] Furthermore, in the above technical solution, the bottom of the frame 1 is fixedly equipped with support legs 12, and the bottom of the support legs 12 is rotatably equipped with traveling wheels 13, which facilitates the movement of the equipment during actual work. At the same time, for relatively compact materials or wood, the equipment can be moved forward a certain distance after each drilling and rising of the sleeve drill bit 3, so that the sleeve drill bit 3 and the sawing plate 5 can gradually move forward and repeatedly cut, forming multiple sets of repeated cutting areas in the material, making the remaining solid structure more dispersed and easier to clean. For longer grooves, this method can also be used to gradually increase the length of the groove, thereby greatly improving the adaptability and practicality of the device.

[0026] Working principle: Multiple sets of sleeve drill bits 3 are installed below the lifting frame 2, and a sawing plate 5 is installed on the outside of the sleeve drill bits 3. In actual use, the frame 1 is set outside the required grooving area. The hydraulic cylinder 11 drives the lifting frame 2 to descend, while the sleeve drill bits 3 rotate and the sawing plate 5 moves repeatedly on the outside of the sleeve drill bits 3. During the descent of the lifting frame 2, each sleeve drill bit 3 drills multiple parallel holes in the material. At the same time, the reciprocating motion of the sawing plate 5 cuts off the uncut solid parts remaining between two adjacent holes, and cuts along the common tangent line of the holes drilled by two adjacent sleeve drill bits 3, causing this part of the solid material to detach from the connection and finally form a groove between it and the holes drilled by the sleeve drill bits 3. Figure 4The long groove shown is processed as follows. After the processing is completed, the lifting frame 2 is lifted, and the solid parts cut off by the sleeve drill bit 3 and the sawing plate 5 are broken by impact or removed one by one with the help of a small cutting machine. This material can be removed to form the required groove. If the processing is done on soil, the solid parts can be directly removed. If the shape of the groove is required to be strict, further processing can be carried out on the above-mentioned groove. Since the equipment has already processed the general shape of the groove, it is convenient for processing machinery to enter even for subsequent fine processing, and there is no need to process too much material. This greatly improves the overall efficiency of the groove forming process. At the same time, after each drilling and rising of the sleeve drill bit 3, the equipment can be moved forward a certain distance, so that the sleeve drill bit 3 and the sawing plate 5 can gradually move forward and cut repeatedly, forming multiple sets of repeated cutting areas in the material, making the remaining solid structure more dispersed and easier to clean. For longer grooves, this method can also be used to gradually increase the length of the groove, thereby greatly improving the adaptability and practicality of the device.
