Description

Technical Field

[0001] This utility model relates to the technical field of equipment for building construction, specifically to a trenching device for engineering construction. Background Technology

[0002] Trenching is a common task in engineering and construction operations. Currently, the commonly used trenching equipment is generally excavators or chain-driven trenching machines. Excavators can flexibly dig trenches according to depth and width, but their digging efficiency is relatively low. Chain-driven trenching machines have relatively high trenching efficiency, but it is not convenient to adjust the width of the trench during digging.

[0003] To facilitate adjustment of trench depth and width while achieving efficient trenching, we propose a trenching device for engineering construction. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a trenching device for engineering construction, which can easily adjust the depth and width of trenching while efficiently digging trenches.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A trenching device for engineering construction includes:

[0007] The frame is a structure in which the top and bottom of the U-shaped rod are open respectively, and the upper parts of the two side rods are fixedly connected by cylindrical rods, and the middle rod of the side plate is a diagonal rod;

[0008] The hydraulic rod has a bearing seat that is rotatably sleeved on a cylindrical rod at the piston shaft end.

[0009] The pivot is detachably installed between the bottoms of the two side rods;

[0010] The motor is mounted and fixed to the bottom of a side rod and is used to drive the shaft to rotate, while also being rotatably connected to the shaft.

[0011] The trenching disc is detachably mounted on the rotating shaft, and multiple trenching discs are evenly arranged along the axial direction of the rotating shaft, with each trenching disc tightly attached to the other. The trenching disc has a pre-drilled mounting hole in the middle of the disc body, and the side wall is covered with conical spikes. The size of the trenching discs that can be replaced is different.

[0012] As an improvement, each end of the rotating shaft is detachably connected to a splicing shaft, which is rotatably sleeved onto the ends of the two side rods. One of the splicing shafts is connected to a motor drive. Each end of the rotating shaft has a tenon, and the splicing end of the splicing shaft has a mortise. After the tenon and mortise are engaged, they are then fixed together with bolts. This allows for convenient assembly and disassembly of the rotating shaft.

[0013] As an improvement, bushings are also included; the central part of the rotating shaft forms a hexagonal shaft structure. After the trenching discs are movably fitted onto the hexagonal shaft through mounting holes, bushings that are movably fitted onto the hexagonal shaft are respectively attached to both sides of each trenching disc. The bushings are hexagonal cylindrical structures and are fixed to the hexagonal shaft by a positioning structure. The positioning structure is bolt two, and the bushings are fixed to the hexagonal shaft by bolt two. This allows the trenching discs to be easily installed and removed, and thus easily replaced.

[0014] It is worth mentioning that the motors and hydraulic rods used in this technical solution are all existing devices that are common knowledge, and their use and control methods are all existing technologies.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. When in use, this new type of device can dig a hole on the ground by rotating the digging disc on the rotating shaft driven by the motor. Then, the device can be towed by a tractor while digging the hole, which allows the device to dig a ditch efficiently on the ground.

[0017] 2. In use, since both the rotating shaft and the trenching disc can be easily installed and removed, the trenching disc can be easily replaced. By replacing the trenching disc, trenching of different depths and widths can be carried out. Attached Figure Description

[0023] In the description of this utility model, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] A trenching device for engineering construction includes:

[0026] rack, such as Figure 2 As shown, the top and bottom of the convex rod are opened respectively, and the upper parts of the two rods 1 are fixedly connected by cylindrical rods 2. The middle rod of the side plate 1 is a diagonal rod, and three cylindrical rods 2 are provided.

[0027] The hydraulic rod 3 has a bearing seat 4 that is rotatably sleeved on a cylindrical rod 2 at the piston shaft end.

[0028] The rotating shaft 5 has two detachable splicing shafts 7 at its ends. The two splicing shafts 7 are rotatably sleeved on the ends of the two side rods 1, and one of the splicing shafts 7 is driven by a motor 14. The motor 14 is mounted and fixed to the bottom of one side rod 1. The two ends of the rotating shaft 5 have tenons 8, and the splicing ends of the splicing shafts 7 have mortises 9. After the tenons 8 and mortises 9 are fitted together, they are fixed together by bolts 10.

[0029] The trenching disc 6 and bushing 11; the rotating shaft 5 forms a hexagonal shaft 12 structure in the middle. After the trenching disc 6 is movably fitted onto the hexagonal shaft 12 through the mounting holes, the two sides of each trenching disc 6 are respectively tightly fitted with bushings 11 that are movably fitted onto the hexagonal shaft 12. The bushing 11 is a hexagonal cylindrical structure and is fixed onto the hexagonal shaft 12 by bolts 13. Seven trenching discs 6 are evenly arranged along the axial direction of the rotating shaft 5, and each trenching disc 6 is tightly fitted to each other. The trenching disc 6 is a disc body with a pre-reserved mounting hole in the middle and a structure with conical spikes on the side wall.

[0030] In the specific implementation of this embodiment:

[0031] The frame and hydraulic rod 3 are respectively mounted on the tractor, and the top of the frame and the base of the hydraulic rod 3 are hinged to the tractor. The operation of the hydraulic rod 3 drives the frame to rotate up and down, thereby affecting whether the trenching disc 6 contacts the ground and adjusting the trenching depth. After the motor 14 drives the trenching disc 6 to rotate, the tractor pulls the device across the ground, thus enabling trenching operations.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
