Description

Technical Field

[0001] The invention relates to the technical field of construction tools, and in particular to a backfilling tool. Background Art

[0002] The ecological slope protection technology of flattening slopes has been widely promoted and applied in production practice, and has achieved good ecological slope protection effects, providing a better solution for the ecological protection of highway and water conservancy project slopes.

[0003] One of the key technologies of the ecological slope protection technology for converting slopes to flat areas is that after the planting soil is backfilled, the depth between the soil surface inside the block and the upper edge of the block should be maintained at 2cm-5cm as a storage space to control soil and water loss. This is the key to whether the ecological slope protection technology for converting slopes to flat areas can play a role in conserving soil and intercepting and utilizing precipitation.

[0004] At present, the conventional way to backfill soil is to use ordinary shovels from the upper part of the slope to clean up the excess soil on the top of the blocks, and to take out some soil from the blocks filled with soil to meet the requirements of the retention space. Not only is the construction cumbersome and slow, but it is also extremely inconvenient, the retention space is uneven, the construction efficiency is low, and the project quality is difficult to control. This problem even leads to some projects almost directly filling the planting troughs without leaving the retention space for soil and water conservation, which directly affects the function of intercepting sediment and rainwater of the slope-to-flat ecological slope protection technology, wastes backfill soil resources, and raises the cost of the backfill project; moreover, because the planting soil is backfilled more, it cannot effectively intercept rainwater, resulting in poor soil moisture in the blocks of the slope-to-flat ecological slope protection technology, poor site conditions for the growth of slope protection plants and unable to grow normally, affecting the normal performance of the ecological slope protection effect of the slope-to-flat ecological slope protection technology.

[0005] In order to solve this practical construction problem, improve the construction speed, ensure the quality of the project, and ensure the effect of ecological slope protection, it is urgently necessary to develop an efficient and convenient special construction tool to control the amount of planting soil backfill during construction, so as to ensure the normal realization of the comprehensive benefits of the slope-to-flat ecological slope protection technology. Summary of the invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the prior art that the backfilling operation of planting soil is complicated and the difference in the backfilling amount of planting soil within the building blocks is large, thereby providing a backfilling tool that simplifies the backfilling operation of planting soil and can reduce the difference in the backfilling amount of planting soil within the building blocks.

[0007] To solve the above problems, the backfilling tool of the present invention is suitable for backfilling a piece to be backfilled, wherein the piece to be backfilled has a cleaning end that needs to be cleaned, and a backfilling groove arranged inside the piece to be backfilled, the opening of which is located at the cleaning end. The backfilling tool includes a spade, an outer frame and an inner spade plate. The outer frame is arranged on the spade and is adapted to the shape of the cleaning end; the inner spade plate is arranged on the spade or the outer frame and is located on the inner side of the outer frame. The inner spade plate has a working part that extends out of the outer frame and extends into the backfilling groove.

[0008] The setting direction of the outer frame is the same as the setting direction of the inner shovel plate.

[0009] The minimum distance between the outer frame and the inner shovel plate is the thickness of the cleaning end.

[0010] One end of the working part away from the outer frame is arc-shaped, circular or triangular.

[0011] The inner shovel plate is in the shape of a curved surface, a flat surface or a folded plate.

[0012] The piece to be backfilled is a polygonal building block, and the shape of the outer frame is one half of the side of the building block.

[0013] The to-be-backfilled piece is a hexagonal building block, and the outer frame is a trapezoid with the lower bottom removed that is adapted to the continuous three-sided shape of the building block.

[0014] The inner shovel plate is arranged on the shovel pants.

[0015] The outer frame is installed at one end of the spade pants, and the other end of the spade pants is inclined to a side away from the working part.

[0016] The technical solution of the present invention has the following advantages:

[0017] 1. The backfilling tool of the present invention comprises a spade, an outer frame and an inner spade plate. The outer frame is arranged on the spade and is adapted to the shape of the cleaning end. The inner spade plate is arranged on the spade or the outer frame and is located on the inner side of the outer frame. The inner spade plate has a working part extending out of the outer frame and extending into the backfilling groove. When the backfilling tool is in use, the outer frame can clean the planting soil on the cleaning end, and the working part of the inner spade plate extends into the backfilling groove to control the backfilling amount of the planting soil in the backfilling groove. The operator can clean the cleaning end and control the backfilling amount of the planting soil in the backfilling groove with a single horizontal pull, and the operation is simpler and more convenient. Moreover, the backfilling quality is easier to control by the working part than by the subjective control of the operator, and the phenomenon of uneven backfilling amount of planting soil in the block can be avoided. The tool can increase the backfilling construction speed by multiples or even several times. Moreover, the backfilling tool has a simple structure and low cost.

[0018] 2. The backfilling tool of the present invention sets the inner shovel plate on the shovel pants. Firstly, it is convenient for processing and manufacturing. Secondly, compared with setting the inner shovel plate on the outer frame, the stress on the connection between the inner shovel plate, the outer frame and the shovel pants is smaller and it is not easy to break. The service life of the backfilling tool is longer.

[0019] 3. In the backfilling tool of the present invention, the outer frame is installed at one end of the shovel, and the other end of the shovel is inclined to a side away from the working part, so as to facilitate the use of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The backfilling tool of this embodiment is suitable for backfilling a piece to be backfilled, wherein the piece to be backfilled has a cleaning end 12 to be cleaned, and a backfilling groove 11 arranged inside the piece to be backfilled, the opening of which is located at the cleaning end 12. Figure 5 As shown, the backfilled piece is a hexagonal block 1. The backfilling tool comprises a spade 2, an outer frame 3, an inner spade plate 4 and a spade handle 5, wherein the outer frame 3, the inner spade plate 4 and the spade handle 5 are mounted on the spade 2.

[0030] The outer frame 3 is adapted to the shape of the cleaning end 12, such as Figure 1 As shown in FIG. 4 , the outer frame 3 is a trapezoid with the bottom removed that matches the continuous three-sided shape of the building block 1. When the building block is a cuboid, the outer frame is a triangle that matches two adjacent sides of the cuboid.

[0031] The inner shovel plate 4 is located on the inner side of the outer frame 3, and the inner shovel plate 4 can have various shapes, such as an arc surface, a plane, or a folded plate. The inner shovel plate 4 has a working portion 41 extending out of the outer frame 3 and extending into the backfill groove 11, and the shape of the end of the working portion 41 away from the outer frame 3 can also be various, such as an arc, a circle, or a triangle. In this embodiment, the inner shovel plate 4 is set on the shovel pants 2. Of course, the inner shovel plate 4 can also be set on the outer frame 3, but when it is set on the outer frame 3, the external force on the connection between the outer frame 3 and the shovel pants 2 will increase, making the connection of the outer frame 3 unreliable.

[0032] like Figure 3 As shown, the setting direction of the outer frame 3 is the same as the setting direction of the inner shovel plate 4, and the minimum distance between the outer frame 3 and the inner shovel plate 4 is the thickness of the cleaning end 12 and the thickness of one edge of the building block.

[0033] The outer frame 3 is installed at one end of the shovel pants 2, and the other end of the shovel pants 2 is inclined to the side away from the working part 41. A shovel handle 5 is connected to the other end of the shovel pants 2, and the length of the shovel handle 5 is set according to usage requirements.

[0034] When the backfill tool is in use, Figure 5 As shown, the outer frame 3 contacts the cleaning end 12 on the upper part of the building block 1, and the working part 41 extends into the backfilling groove 11. The shovel handle 5 is pulled in the direction of the arrow, and the planting soil at the cleaning end 12 will enter the backfilling groove 11. The planting soil in the backfilling groove 11 is moved out of the backfilling groove 11 to the building block 1 below. When the cleaning end 12 in the direction of the arrow also needs to be cleaned, the outer frame 3 is used to contact the cleaning end 12 of this part and clean the planting soil above to complete the backfilling work of the building block 1.

[0035] When the backfill tool is in use, the outer frame 3 can clean the planting soil on the cleaning end 12, and the working part 41 of the inner shovel plate 4 extends into the backfill groove 11 to control the backfill amount of the planting soil in the backfill groove 11. The operator can clean the cleaning end 12 and control the backfill amount of the planting soil in the backfill groove 11 with a flat pull action, that is, the cleaning of the remaining soil and the adjustment of the stagnant storage space in the block are completed at one time, the operation is simpler and more convenient, and the construction labor intensity is reduced. The backfill amount of the planting soil in the backfill groove 11 is controlled by the working part 41, and the planting soil amount can be quantified in the process of the slope-to-flat ecological slope protection construction, and the quality of the planting soil backfill project can be improved. It can save up to 30% of the planting soil, save the cost of the planting soil project, and provide acceptance standards for the project acceptance work. Moreover, the stagnant storage space in the block can be conveniently adjusted to ensure the effect of intercepting rainfall, improve soil moisture, provide a good site condition for plant growth, and ensure the realization of the ecological slope protection goal. Backfill tools can ensure storage space, increase the use of natural precipitation, save irrigation water and corresponding maintenance investment in the maintenance link. The backfill tool has a simple structure and low cost.

[0036] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
