[0002] In modern urban infrastructure construction and various industrial projects, the construction of cable trenches is a crucial link. It provides a safe and stable transmission channel for various cables such as power and communications. The filling material of the cable trench, especially the sand layer, plays an indispensable role in protecting the cable. The sand layer can not only reduce the mechanical pressure on the cable, prevent the cable from deformation under external pressure and prevent the cable from catching fire, but also provide a certain heat dissipation effect, reduce the temperature of the cable during operation, and extend the service life of the cable. In addition, the sand layer can also be used as an auxiliary means to locate the cable fault point, which is convenient for rapid troubleshooting and maintenance.

[0003] The traditional sand filling method is inefficient, labor-intensive, and prone to dust pollution, so we proposed a high-efficiency sand filling machine for cable trenches. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-4 The utility model provides a technical solution: first, a cable trench high-efficiency sand filling machine includes a base 1, a motor 2, a transfer box 3, a sand inlet pipe 4, a sand inlet hopper 5, a sand inlet conveying auger 6, a sand outlet pipe 7, a sand outlet 8, a sand outlet conveying auger 9, a sand inlet drive pulley group 10 and a sand outlet drive pulley group 11, wherein the motor 2 and the transfer box 3 are both installed on the upper part of the base 1, an inspection door 31 is installed on the back of the transfer box 3, the sand inlet pipe 4 is connected to the feed inlet at the top of one side of the transfer box 3, the sand outlet pipe 7 is connected to the discharge port at the bottom of the other side of the transfer box 3, the feed inlet of the sand inlet pipe 4 is connected to the sand inlet hopper 5, a sand outlet 8 is reserved at the end of the sand outlet pipe 7, the sand inlet pipe 4 and the sand inlet hopper 5 are internally connected to the sand inlet conveying auger 6 for rotation together, and the sand outlet pipe 7 is internally connected to the sand outlet conveying auger 9 for rotation;

[0029] Secondly, the motor 2 is a dual-axis drive motor, that is, the motor 2 itself has two output shafts (the dual-axis drive motor is an existing well-known technology and will not be described in detail here), one of the output shafts of the motor 2 is connected to the sand-inlet conveying auger 6 through the sand-outlet drive pulley group 11, and the other output shaft of the motor 2 is connected to the sand-outlet conveying auger 9 through the sand-inlet drive pulley group 10, and the sand-inlet drive pulley group 10 and the sand-outlet drive pulley group 11 are composed of a large and a small pulley and a belt, the small pulley is installed on the output shaft of the motor 2, and the large pulley is installed on the sand-inlet conveying auger 6 and the sand-outlet conveying auger 9 respectively;

[0030] A controller (12) is provided on the upper part of the motor (2), and the controller is connected to a power line. When the power is turned on through the power line, the sand filling machine starts working.

[0031] An inverted T-shaped support foot (13) is provided at the lower part of the base (1), and the inverted T-shaped support foot (13) is adapted to be movably fixed in a groove on the ground; this provides better stability and prevents the sand filling machine from shaking or automatically deviating during operation.

[0032] A sand-discharging conveying auger (9) and a sand-inlet conveying auger (6) are arranged inside the transfer box (3). The outer diameter of the spiral blades of the sand-inlet conveying auger (6) inside the transfer box (3) is larger than the outer diameter of the spiral blades of the sand-discharging conveying auger (9). Different proportions are achieved by using spiral blade outer diameters of different sizes, so that the sand inside the transfer box (3) is filled up faster, which is equivalent to the effect of the gear speed ratio. The larger the sand intake, the greater the sand density inside. The sand-discharging conveying auger 9 is more efficient in discharging sand. The sand will not form lumps during the squeezing process inside because the sand-inlet conveying auger (6) continuously sends sand inside and the sand-discharging conveying auger 9 continuously sends sand outside, thus realizing a circulation process.

[0033] Finally, the discharge section of the sand inlet and conveying auger 6 and the feed section of the sand outlet and conveying auger 9 are both located inside the transfer box 3, so that the sand inlet and conveying auger 6 can transport the sand into the transfer box 3, and the sand outlet and conveying auger 9 can also transfer the sand inside the transfer box 3 out.

[0034] The cable trench high-efficiency sand filling machine of this embodiment, when working, the two output shafts of the motor 2 correspondingly drive the sand inlet conveying auger 6 and the sand outlet conveying auger 9 to rotate at high speed through the sand inlet transmission pulley group 10 and the sand outlet transmission pulley group 11, and the sand inlet hopper 5 will be connected with the hopper storing sand. When the sand inlet conveying auger 6 rotates, the sand will enter the sand inlet hopper 5 and be transported to the interior of the transfer box 3 through the sand inlet pipe 4 and fall on the bottom end of the interior of the transfer box 3. After the sand outlet conveying auger 9 rotates, the sand that has fallen on the bottom end of the interior of the transfer box 3 will be transported out through the sand outlet pipe 7 and finally discharged from the sand outlet 8. For the specific sand conveying path, please refer to Figure 5 .

[0035] The auger-type high-efficiency sand filling machine for cable trenches has been widely recognized for its application in actual projects. Its high efficiency and precision have brought significant improvements to the cable trench filling work. In a large-scale urban power transformation project, the introduction of the auger-type sand filling machine has shortened the sand filling work that originally required dozens of workers to spend several days to just a few hours, significantly improving the sand filling efficiency and reducing labor costs.
