[0002] The trench excavation device for water conservancy projects is mainly used in the construction of water conservancy projects. It is a mechanical equipment or device used for excavating trenches. The equipment consists of an engine, a walking mechanism and a transmission system. It has the characteristics of high construction efficiency and minimal surface damage. It is mainly used in farmland, water conservancy, pipeline laying and municipal engineering.

[0003] Patent CN220225502U discloses a trenching machine for water supply and drainage pipeline engineering, belonging to the technical field of water conservancy engineering construction equipment. It consists of a frame, a water spray component, an adjusting frame, a primary excavation mechanism, and a secondary excavation mechanism. The water spray component is mounted on the frame, and an adjusting frame is mounted on one side of the frame. The primary excavation mechanism is mounted on the adjusting frame via an electric lifting rod. The secondary excavation mechanism is mounted on the adjusting frame above the primary excavation mechanism via a screw motor and a transmission screw. The primary and secondary excavation mechanisms are connected by a transmission mechanism. This trenching machine for water supply and drainage pipeline engineering adjusts the relative positions of the primary and secondary excavation mechanisms to adjust the required trench width, accommodating water supply and drainage pipes of different diameters. This trenching machine solves the problems of existing trenching machines' inability to adjust trench width, poor versatility, and low trenching efficiency.

[0004] The above-mentioned device has certain shortcomings when in use: when excavating trenches, the device uses a milling and throwing disc to dig on the ground, but a lot of soil is generated and accumulates in the trench during the excavation process, which requires manual cleaning and results in a lot of inconvenience.

[0005] Therefore, this utility model provides a trench excavation device for water conservancy engineering construction to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a trench excavation device for water conservancy engineering construction, which solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a trench excavation device for water conservancy engineering construction, including a mobile frame, a U-shaped frame fixedly installed in the middle of the top wall of the mobile frame, a grooving component fixedly installed in the top wall of the U-shaped frame, positioning components fixed to the grooving component installed on the outer side wall of the U-shaped frame, buffer components installed at the four corners of the bottom wall of the mobile frame, and a conveying component installed on the bottom wall of the mobile frame at the position of the sludge discharge area of ​​the grooving component;

[0008] The grooving assembly includes a lifting push rod fixedly installed at the center of the top wall of the U-shaped frame. The movable end of the lifting push rod slides through the U-shaped frame and is fixedly installed on a U-shaped seat. A milling and polishing disc is rotatably installed on the inner wall of the U-shaped seat. Several grooving claws are evenly arranged in a circular pattern on the outer wall of the milling and polishing disc. Each of the grooving claws has a storage cavity inside. A drive motor is fixedly installed on the front wall of the U-shaped seat. The power shaft of the drive motor passes through the U-shaped seat and is fixedly connected to the axis of the milling and polishing disc through a bearing.

[0009] The conveying assembly includes a fixed frame that is fixedly installed on the left side of the bottom wall of the mobile frame. A conveying cylinder is fixedly installed on the inner wall of the fixed frame. An auger is rotatably installed on the inner wall of the conveying cylinder. A drive motor is fixedly installed on the side wall of the conveying cylinder. The drive shaft of the drive motor passes through the conveying cylinder and is fixedly connected to the drive shaft of the auger through a bearing.

[0010] Through the above technical solution, the grooving component can meet the diverse grooving depth requirements in water conservancy engineering construction by controlling the working depth of the milling and grooving claws. Excess soil generated during the grooving process can be transported away by the conveying component.

[0011] Furthermore, both sides of the top wall of the U-shaped seat are fixedly connected to the positioning components, and the drive motor is used to drive the milling and polishing disc to rotate counterclockwise.

[0012] The above technical solution uses a high-power motor to drive the milling disc and grooving claw to dig trenches on the ground.

[0013] Furthermore, the top wall of the conveying cylinder, where the corresponding slotted claw rotates and descends to discharge mud through the storage chamber, is connected to a receiving end, and the outer wall of the conveying cylinder, near the drive motor, is connected to a discharge pipe.

[0014] The above technical solution is mainly used to receive the soil stored in the grooving claw and storage cavity, and then transport it to the outside of the trench through the discharge pipe driven by the auger.

[0015] Furthermore, the positioning component includes a positioning block fixedly installed on the outer wall of the U-shaped frame, and a positioning rod fixedly installed on the top wall of the U-shaped seat at the position corresponding to the positioning block. Both positioning blocks have circular cavities inside.

[0016] Through the above technical solution, the positioning block can limit the movement path of the positioning rod and prevent path deviation.

[0017] Furthermore, each of the circular cavities is equipped with an electromagnet ring, and the inner walls of the two electromagnet rings are slidably connected to the outer walls of the corresponding positioning rods.

[0018] Through the above technical solution, the electromagnet ring is attracted and fixed to the outer wall of the positioning rod after being energized, which can keep the groove depth consistent.

[0019] Furthermore, the buffer assembly includes a support cylinder fixedly installed on the bottom wall of the mobile frame, a buffer is vertically installed inside the support cylinder, and a support rod is fixedly installed at the bottom end of the buffer.

[0020] Through the above technical solution, the buffer installed inside the support cylinder can buffer and absorb the vibration generated by the entire device when passing through bumpy roads, reduce the amplitude of the bumps and maintain the stability of the entire device.

[0021] Furthermore, the bottom of the support rod is rotatably mounted with casters, and a traction device is fixedly mounted on the side wall of the mobile frame.

[0022] Through the above technical solution, the casters support the entire device and move it after being connected to the traction device via an external traction device.

[0023] Beneficial effects

[0024] This utility model provides a trench excavation device for water conservancy engineering construction. Compared with the prior art, it has the following advantages:

[0025] (1) The trench excavation device for water conservancy construction, through the setting of trenching components and conveying components, can control the trench excavation depth for different engineering constructions during the implementation of water conservancy projects, meet diverse construction needs, and continuously transport the excess soil generated during the trench excavation process to the outside of the trench, avoiding the accumulation in the trench and the need for additional cleaning, reducing the engineering construction process, and also having an auxiliary effect on improving the efficiency of trench excavation.

[0026] (2) The trench excavation device for water conservancy construction, through the setting of positioning components, mainly limits the lifting path of the U-shaped seat and the milling and throwing disc, so that it always moves along the designed route. When it is necessary to fix the construction depth of the milling and throwing disc, the U-shaped seat is kept in place by adsorption and fixation of the positioning rod. When the milling and throwing disc is pulled and moved, the lateral force it receives is distributed to the U-shaped seat and the milling and throwing disc through the setting of the positioning rod, thereby increasing the overall strength and working stability.

[0027] (3) The trench excavation device for water conservancy construction, through the setting of buffer components, when the whole device is moving and excavating, after passing through the bumpy ground, the buffer can buffer and absorb the energy of the bumpy vibration generated, so as to avoid the problem of trench deviation or misalignment caused by the bumpy of the whole device.

[0036] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1:

[0038] Please see Figures 1-7 A trench excavation device for water conservancy engineering construction includes a mobile frame 1, a U-shaped frame 2 fixedly installed in the middle of the top wall of the mobile frame 1, a grooving component 3 fixedly installed in the top wall of the U-shaped frame 2, positioning components 4 fixed to the grooving component 3 installed on the outer side walls of the U-shaped frame 2, buffer components 6 installed at the four corners of the bottom wall of the mobile frame 1, and a conveying component 5 installed on the bottom wall of the mobile frame 1 at the mud discharge area of ​​the grooving component 3.

[0039] The grooving assembly 3 includes a lifting push rod 31 fixedly installed at the center of the top wall of the U-shaped frame 2. The movable end of the lifting push rod 31 slides through the U-shaped frame 2 and is fixedly installed with a U-shaped seat 32. A milling and polishing disc 33 is rotatably installed on the inner wall of the U-shaped seat 32. Several grooving claws 35 are evenly installed in a circular arrangement on the outer wall of the milling and polishing disc 33. Each of the several grooving claws 35 has a storage cavity 36 inside. A drive motor 34 is fixedly installed on the front wall of the U-shaped seat 32. The power shaft of the drive motor 34 passes through the U-shaped seat 32 through a bearing and is fixedly connected to the axis of the milling and polishing disc 33. The two sides of the top wall of the U-shaped seat 32 are fixedly connected to the positioning assembly 4. The drive motor 34 is used to drive the milling and polishing disc 33 to rotate counterclockwise.

[0040] The conveying assembly 5 includes a fixed frame 51 fixedly installed on the left side of the bottom wall of the movable frame 1. A conveying cylinder 52 is fixedly installed on the inner wall of the fixed frame 51. An auger 56 is rotatably installed on the inner wall of the conveying cylinder 52. A drive motor 55 is fixedly installed on the side wall of the conveying cylinder 52. The power shaft of the drive motor 55 passes through the conveying cylinder 52 through a bearing and is fixedly connected to the power shaft of the auger 56. A receiving end 53 is connected to the top wall of the conveying cylinder 52 and the position corresponding to the slotted claw 35 rotating and descending to discharge mud through the storage cavity 36. A discharge pipe 54 is connected to the outer wall of the conveying cylinder 52 and the position near the drive motor 55.

[0041] In this embodiment of the utility model, the purpose of this arrangement is that, with the cooperation of the grooving component 3 and the conveying component 5, the trenching depth can be controlled during the excavation of trenches in the construction of water conservancy projects, and the excavation can be adapted to different design specifications. The excess soil generated during the trenching process is transported to the outside of the trench through the auger 56 in the conveying component 5, so as to avoid the problem of soil accumulation.

[0042] Example 2:

[0043] Please see Figures 1-7 This embodiment provides a technical solution based on embodiment one: the positioning component 4 includes a positioning block 41 fixedly installed on the outer wall of the U-shaped frame 2, and a positioning rod 44 fixedly installed on the top wall of the U-shaped seat 32 at the position corresponding to the positioning block 41. Both positioning blocks 41 have a circular cavity 42 inside, and an electromagnet ring 43 is installed inside the circular cavity 42. The inner walls of the two electromagnet rings 43 are slidably connected to the outer wall of the corresponding positioning rod 44.

[0044] In this embodiment of the utility model, the purpose of this setting is that the positioning component 4 is mainly to limit the lifting path of the U-shaped seat 32. When it is necessary to keep the position of the U-shaped seat 32 unchanged, the positioning rod 44 is attracted and fixed to the outer wall by energizing the electromagnet ring 43, so as to prevent the positioning rod 44 from moving down. When the whole device is moving, the milling and polishing disc 33 will generate a lateral force by digging the groove, and the positioning rod 44 will provide additional linear support and strength.

[0045] Example 3:

[0046] Please see Figures 1-7 This embodiment provides a technical solution based on embodiment one: the buffer assembly 6 includes a support cylinder 61 fixedly installed on the bottom wall of the mobile frame 1, a buffer 62 is vertically installed inside the support cylinder 61, a support rod 63 is fixedly installed at the bottom end of the buffer 62, a universal wheel 64 is rotatably installed at the bottom end of the support rod 63, and a traction device 7 is fixedly installed on the side wall of the mobile frame 1.

[0047] In this embodiment of the utility model, the purpose of this arrangement is that the buffer component 6, when the entire device is moving, can buffer and absorb the vibration caused by passing through the bumpy road surface through the support cylinder 61 and the buffer 62, reduce the amplitude of the entire device's swaying, and improve the stability of the equipment during the engineering construction process.

[0048] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0049] The working principle of this device is as follows: It is connected to the traction device 7 through an external traction device, and is electrically connected to the lifting push rod 31, drive motor 34, electromagnet ring 43, and transmission motor 55 through the power supply and controller of the external traction device. When it starts working, the external traction device drives the entire device to move. When the moving frame 1 moves, it drives the buffer assembly 6 to move. When the caster wheel 64 rolls along the ground over a bumpy road, it will cause the support rod 63 and the buffer 62 to extend and retract. Since the buffer 62 is assembled from a shock-absorbing spring and a damper, the vibration problem caused by the caster wheel 64 over a bumpy road can be buffered and absorbed by the buffer 62, reducing the shaking problem of the entire device.

[0050] The milling and polishing disc 33 and the grooving claw 35 are driven by the drive motor 34 to rotate inside the U-shaped seat 32. The lifting push rod 31 pushes the U-shaped seat 32, the milling and polishing disc 33 and the grooving claw 35 to descend. As the milling and polishing disc 33 and the grooving claw 35 rotate counterclockwise inside the U-shaped seat 32, the grooving claw 35 performs grooving and excavation along the ground at the location.

[0051] When the U-shaped seat 32 descends, it drives the positioning rod 44 to descend inside the electromagnet ring 43 and the positioning block 41, which limits the descent path of the U-shaped seat 32 and the milling and polishing disc 33, prevents positional deviation, and provides support strength for the pressure on the U-shaped seat 32 and the milling and polishing disc 33.

[0052] After the U-shaped seat 32 drives the milling and polishing disc 33 to descend to the predetermined depth, the position of the positioning rod 44 is limited after the electromagnet ring 43 is energized. As the entire device moves slowly and the milling and polishing disc 33 and the grooving claw 35 rotate continuously, the groove is opened. The storage cavity 36 opened inside the grooving claw 35 can store the soil produced by excavation.

[0053] As it rotates to the top of the receiving end 53, the soil inside the storage chamber 36 will pour down into the receiving end 53. The auger 56 is driven to rotate by the drive motor 55, and the soil that has entered the receiving end 53 and the conveying cylinder 52 is transported by the auger 56 and discharged to the outside of the trench through the discharge pipe 54. This allows the entire device to control the trenching depth during trenching and to transport the soil generated during the excavation process out without the need for additional manual excavation.

[0054] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
