[0028] Since the traditional fertilizer groove backfill method mainly relies on the direct dumping of muck car or forklift, the backfill soil of this method often contains stone, garbage, sundries, brick slag and other impurities, which leads to poor backfill quality and adverse effects on underground structure and pipeline. In the underground engineering with complex structure, narrow space, deep depth and complex surrounding environment, traditional machinery is difficult to enter the backfill site, and manual backfill is inefficient and difficult to ensure the compaction degree.

[0030] The utility model discloses the combination of screening feed and conveying device, can effectively screen raw soil, remove impurities, ensure the quality of backfill soil, to improve the overall quality of foundation pit backfill. Subsequent cooperation small compactor or artificial rammer to backfill soil is compacted in layer. The above embodiment adopts automatic conveying device, can realize continuous feeding, screening and conveying, reduces manual operation, improves construction efficiency. Feed mechanism is located at the feed end of the conveying device, backfill soil after screening falls on the conveying device, and is transported to backfill end by the conveying device and falls into backfill position, and compact design can adapt to limited working space, facilitate construction in narrow site.

[0031] Advantageously, the conveying device adopts belt conveyor, its driving mechanism 1 is fixed to feed end, transmission wheel 6 is fixed to backfill end, conveying belt 5 is driven between the driving mechanism 1 and the transmission wheel 6, and a plurality of parallel arranged supporting rollers 4 are arranged between the driving mechanism 1 and the transmission wheel 6.

[0032] Each supporting roller 4 adopts lower support mode, is supported at the bottom of conveying belt 5 in conveying direction, and the bottom is connected with the top of support 7.

[0033] The role of supporting roller in belt conveyor is mainly to support and guide conveying belt, ensure stable operation and reduce sagging degree. In addition, supporting roller can also reduce the friction between conveying belt and driving mechanism and transmission wheel, thereby prolonging the service life of conveying belt.

[0034] Supporting roller transmits power by the friction between transmission wheel 6 and conveying belt 5. Soil after screening falls into one end of conveying belt, and material is conveyed to the other end under the traction of transmission wheel and falls into backfill position.

[0035] The possible structural mode of supporting roller has the following several kinds: plane supporting roller, concave supporting roller, roller supporting roller and elastic supporting roller can be used.

[0036] Plane supporting roller: the surface of this supporting roller is flat, mainly used for supporting and guiding conveying belt.

[0037] Concave roller: the surface of this roller is concave, which can better adapt to the shape of the conveyor belt and reduce friction.

[0038] Roller roller: this roller is composed of multiple rollers, which can provide better support and guiding effect.

[0039] Elastic roller: this roller has elasticity, which can absorb energy when impacted and protect the conveyor belt from damage.

[0040] In the embodiment of the utility model, the feeding mechanism includes feeding hopper 2 and vibration screen 3, the feeding hopper 2 is fixed to the feeding end of the conveying device through the support, and the outlet thereof faces the conveying device, and the vibration screen 3 is installed in the feeding hopper, the vibration screen 3 is a multi-layer screening assembly, and the vibration filtering of the raw soil forms the backfill soil. The support can be a steel rod. The vibration screen 3 can be stainless steel or metal mesh, the screen can have more than two layers, and the screen hole diameter gradually decreases from top to bottom. The screen shape can be circular, square, rectangular and the like, matched with the feeding hopper. The vibration can be realized by a motor-driven mechanical vibration mode.

[0041] In one embodiment of the utility model, the conveying device includes a driving mechanism 1, the driving mechanism 1 has a conveying motor and a vibration motor, the screen divides and the conveying is carried out, the conveying motor provides power for driving the backfill soil, and the vibration motor drives the vibration screen 3 to vibrate.

[0042] In the specific embodiment of the utility model, the conveying motor and the vibration motor can be arranged on both sides of the bottom of the vibration screen, can be symmetrically arranged, or can be staggered arranged.

[0043] Specifically, the conveying motor and the vibration motor can be coaxially arranged, and the conveying motor and the vibration motor are arranged on the same axis, and the backfill soil and the vibration screen are driven at the same time through a common transmission system (such as a universal joint). This arrangement can simplify the structure and reduce the occupied space.

[0044] Parallel arrangement can also be used, and the two motors are arranged in parallel, and each is connected to the corresponding working part through an independent transmission device. This arrangement is convenient for maintenance and replacement of parts, but may increase the width of the equipment.

[0045] Vertical stacking can also be used, and the motors are arranged in a compact space, and the power is transmitted through gears or belt pulleys. This design helps to save space, but may require a more complex transmission mechanism.

[0046] Specifically, the actual installation position can be selected.

[0047] The vibration motor and the shell of the vibration screen are connected and driven by a chain gear.

[0048] The connection mode of the vibration motor and the vibration screen can be direct driving, the vibration motor is directly fixed on the vibration screen, and the excitation force is generated through the eccentric block of the motor to make the screen vibrate.

[0049] Indirect driving can also be adopted, and transmission elements such as chains, gears or belts are used to transmit power of the vibration motor to the vibration screen. This mode can provide greater flexibility, allowing the relative position between the motor and the screen to be adjusted. In the utility model, this arrangement is preferred to improve the compactness of the structure.

[0050] In the above embodiments, the support 7 is formed by welding steel pipes to form a steel frame. The feed hopper 2 is in the shape of an inverted trapezoid with a large top opening and a small bottom outlet, and the outlet width of the feed hopper 2 is less than or equal to the width of the conveying device.

[0051] The use of a steel frame formed by welding steel pipes can significantly improve the stability and carrying capacity of the entire support. This structural design can ensure that the support is not easily deformed or damaged when subjected to a large weight or external force, thereby ensuring the normal operation and safety of the equipment.

[0052] The feed hopper 2 is designed in the shape of an inverted trapezoid with a large top opening and a small bottom outlet. This shape helps the material to flow smoothly to the vibration screen under the action of gravity. The large top opening facilitates rapid filling of the original soil, while the small bottom outlet allows precise control of the material flow rate.

[0053] Since the outlet width of the feed hopper 2 is less than or equal to the width of the conveying device, this can ensure that the material does not leak or scatter during transfer due to size mismatch.

[0054] In the description of the utility model, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model.

[0055] In use, the original soil material is placed into the hopper from the top opening using a shovel, and the vibration screen can screen out hard impurities such as garbage, tree roots and stones under the drive of the vibration motor. According to the different soil conditions on site, the frequency of the vibration motor is adjusted reasonably, and the treatment efficiency of the earthwork is also taken into account while fully screening the garbage, so as to balance the utilization rate and the passing rate of the soil body.

[0056] The utility model discloses a conveying belt for backfilling soil, which belongs to the field of construction machinery.

[0057] The utility model is suitable for a wide range of applications, and is not only suitable for conventional backfilling of a trench, but also suitable for scenarios such as backfilling of soil, transportation of backfilling materials, and the like, which require high backfilling quality, narrow space, complex surrounding structure, small construction operation area, long-distance transportation of a large amount of earthwork, and the like, and cannot be reached by general transportation machinery.

[0058] Compared with the conventional backfilling method using a shovel to backfill in layers and steps, the utility model has obvious advantages, and can obviously save transportation cost and time cost.

[0059] For example, in an embodiment in which a competition pool trench needs to be backfilled by about 500m 3 , and a training pool trench needs to be backfilled by about 400m 3 , if a tower crane is used to transport backfilling soil, 1m 3 is transported each time, 10 minutes are spent for single hoisting, 10 hours are worked each day, and the tower crane can be used for hoisting backfilling soil for 3 hours each day, and is used for hoisting other materials such as steel bars and forms for the other time. The total time required is 500 ÷ 1 × 10 ÷ 60 ÷ 3 ≈ 28 days.

[0060] The conveying belt of the utility model is used to transport backfilling soil, instead of a tower crane, a shovel is used to transport backfilling soil to a feeding hopper, 0.8m 3 is transported each time, 1.5 minutes are spent for a single trip, 8 hours are worked each day, and the time required is 900 ÷ 0.8 × 1.5 ÷ 60 ÷ 8 ≈ 3.5 days.

[0061] It can be seen that the scheme of the utility model is used to transport backfilling soil, which greatly improves construction efficiency, obviously saves construction period and reduces construction cost, has high automation degree, controllable speed, and saves labor, and is suitable for transportation of construction materials in different complex environments.
