Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a trench excavation device for water conservancy construction. Background Art

[0002] The trench excavation device is an important process in the construction of water conservancy and hydropower. The types of trench sections generally include straight trenches and trapezoidal trenches. For the trapezoidal trench, the trapezoidal trench is a large trench construction, and the excavation device has a certain slope on the slope. The slope must meet the design and specification requirements, and no support is required. At present, in order to improve work efficiency and reduce labor intensity, a trapezoidal trenching shovel will be installed on the excavator to excavate the trapezoidal trench. The trapezoidal trenching shovel can be used to excavate the trapezoidal trench in one go, improving work efficiency and quality. However, for the edges of the trenches that need to be excavated, there are often some naturally grown weeds on the ground, some weeds with very vigorous root systems, and the roots of these weeds are entangled with each other. When digging with a trapezoidal trenching shovel, the trapezoidal trenching shovel cannot cut off the grass roots on the ground at the edge of the excavated trench. During excavation, the grass roots in the soil brought up by the trenching shovel will drive the surrounding grass roots. The brought up grass roots are not only easy to bring soil into the excavated trapezoidal trench, but also affect the neatness of the edge of the trapezoidal trench, and require subsequent manual repairs. Therefore, a trenching device for water conservancy construction is needed to meet the needs. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A trench excavation device for water conservancy construction is designed, including a trenching shovel, on which two fixing frames are symmetrically fixed, and fixed plates are respectively fixed on the two fixing frames, and both of the two fixed plates are penetrated and rotatably provided with rotating shafts, and cutting knives are fixed on the ends of the two rotating shafts that are away from each other, and a double-axis motor is commonly fixed on the ends of the two rotating shafts that are close to each other, and a plurality of first fixing rods are fixed on the double-axis motor, and the plurality of first fixing rods are respectively fixed on the two fixed plates.

[0006] Preferably, a protective mechanism is provided on both of the fixing plates.

[0007] Preferably, the protection mechanism comprises a protection cover, and the protection cover is rotatably disposed on the two fixed plates.

[0008] Preferably, the protective cover is a U-shaped structure.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Example 1: Reference Figure 1-4 , a trench excavation device for water conservancy construction includes a trenching shovel 1, which is installed on an excavator when in use. Two fixing frames 8 are symmetrically fixed on the trenching shovel 1, and fixing plates 2 are respectively fixed on the two fixing frames 8. The two fixing plates 2 are arranged between the trenching shovel 1 and the excavator through the support of the two fixing frames 8. The two fixing plates 2 are both penetrated and rotatably provided with a rotating shaft 3. Cutting knives 5 are fixed on the ends of the two rotating shafts 3 that are away from each other. A double-axis motor 4 is commonly fixed on the ends of the two rotating shafts 3 that are close to each other. A plurality of first fixing rods 6 are fixed on the double-axis motor 4, and the plurality of first fixing rods 6 are respectively fixed on the two fixing plates 2. The double-axis motor 4 is fixed on the two fixing plates 2 by using the plurality of first fixing rods 6. When the trenching shovel 1 is in use, the two rotating cutting knives 5 between the trenching shovel 1 and the excavator are used to cut the grass roots on the ground at the edges of both sides of the trapezoidal trench in advance, and when the trenching shovel 1 is excavating, the rotating cutting knives 5 will not be inserted too deep into the ground, which reduces the working efficiency of the cutting knives 5 and prolongs the service life of the cutting knives 5.

[0021] During use, when the trenching shovel 1 is controlled by the excavator to dig a trapezoidal trench, the dual-axis motor 4 is in working loading, and the dual-axis motor 4 drives the two cutting knives 5 to rotate simultaneously through the two rotating shafts 3, and the two rotating cutting knives 5 will not contact the grass roots that need to be cut until the trenching shovel 1 digs the soil. This allows the two rotating cutting knives 5 to cut the grass roots on the ground at the edges of both sides of the trapezoidal trench in advance, and can also prevent the two rotating cutting knives 5 from being too deep into the soil. The two rotating cutting knives 5 can cut the grass roots on the ground at the edges of both sides of the trapezoidal trench in advance, so that the grass roots on the ground at the edges of both sides of the trapezoidal trench are broken. When the trenching shovel 1 digs and brings out the soil, the grass roots in the soil will not drive the grass roots on the ground at the edges of both sides of the trapezoidal trench, thereby not only preventing the grass roots from bringing the soil at the edge into the trapezoidal trench, but also ensuring the cleanliness of the edges of both sides of the trapezoidal trench.

[0022] Embodiment 2: In embodiment 1, the dual-axis motor 4 is completely exposed to the outside. When the trenching shovel 1 is digging, soil may occasionally collapse. Some of the collapsed soil may stick to the dual-axis motor 4, which is not conducive to the heat dissipation and cleaning of the dual-axis motor 4. Figure 1 , 3, 4 and 5, as another preferred embodiment of the utility model, the difference from embodiment 1 is that a protective mechanism is commonly provided on the two fixed plates 2, the protective mechanism includes a protective cover 7, the protective cover 7 is rotatably provided on the two fixed plates 2, the protective cover 7 is a U-shaped structure, the U-shaped protective cover 7 blocks the dual-axis motor 4, so that the protective cover 7 can achieve the purpose of protecting the dual-axis motor 4, and the collapsed soil can be directly adhered to the protective cover 7 under the blocking of the protective cover 7, and will not stick to the dual-axis motor 4.

[0023] Two knocking mechanisms are symmetrically arranged above the protective cover 7, and the two knocking mechanisms are respectively fixed on the two fixed plates 2. The knocking mechanism includes a second fixed rod 9, and the second fixed rod 9 is fixed on the fixed plate 2. A plurality of plug-in rods are penetrated and slidably arranged on the second fixed rod 9, and a knocking ball 10 is respectively fixed on one end of the plurality of plug-in rods, and a connecting plate 12 is commonly fixed on the other end. Springs 11 are respectively mounted on the plurality of plug-in rods between the connecting plate 12 and the second fixed rod 9. Under the action of the rebound force of the plurality of springs 11, the positions of the plurality of knocking balls 10 are limited, so that the plurality of knocking balls 10 will not contact the rotated protective cover 7, thereby ensuring that the subsequent pressing of the connecting plate 12 will drive the plurality of knocking balls 10 to knock on the protective cover 7.

[0024] During use, when the protective cover 7 needs to be cleaned, rotate the protective cover 7, let the U-shaped protective cover 7 rotate 180 degrees, let the U-shaped protective cover 7 turn to the ground, and then intermittently press the two connecting plates 12, so that multiple knocking balls 10 intermittently knock the protective cover 7 to knock off the mud stuck on the surface of the protective cover 7, and when turning over the protective cover 7, the impurities that fall into the protective cover 7 can also be poured out.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
