Technical Field

[0001] The invention relates to the technical field of trench backfilling, in particular to fertilizer trench backfilling construction equipment used in building backfilling engineering. Background Art

[0002] In construction projects, a trench is a long trench dug for laying underground facilities (such as pipelines, cables, etc.). It is not only an important part of infrastructure construction, but also plays a key role in ensuring the quality and safety of the project.

[0003] Fertilizer trough backfilling is the process of refilling the excavated soil or other filling materials into the trench. The purpose is to ensure safety, restore function, comply with regulations and promote environmental protection. Through scientific and reasonable backfilling methods and technical means, the overall quality and long-term benefits of the project can be effectively improved. Therefore, fertilizer trough backfilling is not only an indispensable part of construction projects.

[0004] However, the existing fertilizer tank backfill construction equipment used for building backfill engineering has the following shortcomings:

[0005] During the backfilling process of the fertilizer trough, corresponding auxiliary substances need to be added to the original soil according to the different landfill objects. This is mainly to overcome the various limitations of the original soil and optimize the physical, chemical and biological properties of the backfill layer to meet the specific needs of different engineering projects. However, the existing equipment is limited by its own structure, and the addition of auxiliary substances is mostly completed through manual assistance. It is also impossible to effectively measure the amount of auxiliary substances added, which not only results in low backfill efficiency, but also cannot guarantee the quality of the backfill soil, resulting in an unsatisfactory constructed environment and affecting the subsequent service life of the objects in the trough.

[0040] The effect achieved by the entire embodiment 1 is as follows: by presetting the above-mentioned components, the mechanism is provided with the same two processing parts, the purpose of which is to complete the storage, weighing and transfer of soil and auxiliary materials, so that the equipment can uniformly discharge and meter when running, and at the same time do not interfere with each other, and use the coordination of system-related modules to accurately control the release amount of soil and auxiliary materials each time, and ensure the adaptability of pre-added auxiliary materials.

[0042] The effect achieved by the entire embodiment 2 is: by presetting the above-mentioned components, the mechanism adopts a traditional mechanical method to quickly complete the preparation of the soil mixture. After the processing is completed, the auxiliary materials can be fully mixed into the soil to avoid the floating temperature, increase the combination of the two, set a reasonable lowering channel, ensure that the soil mixture can be injected into the fertilizer trough on a large scale, and reduce the difficulty of manual secondary correction.

[0043] Embodiment 3, as Figure 1 , Figure 2 and Figure 3 As shown, a load-bearing plate 5 is fixedly installed on the outer wall of each first external frame 2, connecting seats 6 are fixedly installed on both sides of the outer wall of each load-bearing plate 5, a metal rod 7 is movably inserted inside each connecting seat 6, a roller 8 is fixedly sleeved on the outer wall of each metal rod 7, a flange seat 9 is fixedly installed on the outer walls of the two connecting seats 6, a driving motor 10 is fixedly inserted inside each flange seat 9, and the output end of each driving motor 10 is respectively connected to a corresponding metal rod 7.

[0044] The effect achieved by the entire embodiment 3 is: by presetting the above-mentioned components, the main body of the equipment has the ability to move freely. Since the fertilizer trough is used to place objects, most of which are lines or pipes, the longitudinal length of the fertilizer trough is greater than the lateral width. The equipment spans both sides of the fertilizer trough, which can achieve the effect of intermittent backfilling, while increasing the flexibility of the equipment and further improving the backfilling efficiency of the equipment.

[0045] The working principle of the whole equipment is as follows: start the driving motor 10, utilize the movable connection of the connecting seat 6 and the metal rod 7 to make some rollers 8 obtain power, slowly move in the field until it moves to the beginning of the fertilizer tank, reasonably control the opening of the two driving motors 10, make the equipment turn at a small angle, ensure that the equipment can accurately cross to the two ends of the fertilizer tank, use manual assistance or mechanical coordination to fill the two storage tanks 303 with appropriate amounts of soil and auxiliary materials, synchronously open the two first electric valves 305, open the channel in the first hollow joint 304, and store the materials. The soil and auxiliary materials in the tank 303 can be continuously lowered into the transfer box 311 from a corresponding inclined conduit 306. When the two are fully in contact with the weighing component 312, the weight changes. As the weight increases, the data measured by the weighing component 312 in real time can be imported into the receiving module 313 through the information line 314 and shared with the equipment system module. The two real-time increasing values ​​can be monitored by related modules. When the two data are about to reach the set range, the first electric valve 305 is controlled to open, and the size of the channel in the first hollow joint 304 is adjusted. The lowering rate of soil and auxiliary materials is adjusted, and finally the two are closed and released. The electric telescopic component 320 is further turned on to retract its inner axis into the cavity, driving the docking block 321 to gradually detach from the corresponding limit groove 319, and the driving component 310 is turned on. The physical properties of the roller bearing 316 are used to drive the two transfer boxes 311 to turn synchronously relative to each other, and start to dump the materials contained in each transfer box 311 into the mixing box 401. After all the materials in each transfer box 311 are dumped, the components are reset immediately, and the servo motor 411 is turned on. The speed reducer 410 transfers the high torque The low-speed power directly acts on the driving gear 412, and utilizes the meshing connection between the driven gear ring 408 and the driving gear 412, and the movable connection between the second transmission rod 402 and the base 403 to slowly drive the stirring blades 405 on each extension plate 404 to rotate inside the mixing box 401, and continuously stir the soil and auxiliary materials. When the time is up, the second electric valve 415 is opened, and the channel in the second hollow joint 413 is opened, and the soil mixture in the mixing box 401 can fall from the rectangular square tube 414 to the inside of the fertilizer trough under its own gravity.

[0046] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
