Description

Technical Field

[0001] This invention relates to the field of water channel production technology, specifically to a high-standard farmland water-saving channel casting and molding device. Background Technology

[0002] A canal casting machine is a device that can pour cement into canals and shape them.

[0003] The existing cast-in-place molding device for water channels mainly includes a cement driving mechanism and a block forming mechanism. During operation, cement concrete needs to be injected into the cement driving mechanism. The screw in the cement driving mechanism will guide the cement concrete into the block forming mechanism. The cement concrete entering the inner cavity of the block forming mechanism forms a U-shape and is left to stand for a period of time until the U-shaped cement blocks are formed.

[0004] However, during the actual pouring process, the agglomeration and forming mechanism remains stationary. Due to the gaps between cement concrete blocks and the presence of gas in these gaps, the presence of gas has two main effects: firstly, it causes honeycomb inside the formed cement blocks, resulting in insufficient hardness of the U-shaped cement pipes after agglomeration; secondly, the presence of gas during the pouring process slows down the accumulation process of cement concrete, reducing efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a high-standard farmland water-saving channel casting device that generates high-frequency vibration during the cement concrete pouring process. This vibration accelerates the aggregation of cement concrete, thereby improving the efficiency of block forming. Furthermore, it reduces the gaps between cement concrete sections to expel internal gas, thereby increasing the hardness of the U-shaped cement pipe after casting, thus solving the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-standard farmland water-saving channel in-situ casting device, comprising a vibration casting mechanism, the structure of which includes an upper U-shaped mold shell that can perform an upper sealing function and has a hollow internal structure, a rotatable collision wing located in the upper U-shaped mold shell, an impact metal rod adapted to the rotating collision wing and generating a vibration effect, and an eccentric wheel located below the collision wing and capable of generating a swaying phenomenon when rotating; and a motion support mechanism, the structure of which includes a lower U-shaped mold shell adapted to the upper U-shaped mold shell and capable of forming the cavity required by the mold, a helical spring that provides elastic support for the lower U-shaped mold shell, and an elastic bandage located at the center of the helical spring and capable of accelerating the reset of the lower U-shaped mold shell.

The edge of the right-angle sealing structure is provided with an integrally formed upper fixing lug.

[0008] Preferably, the depth of the U-shaped shaping cavity is consistent with the thickness of the cement channel.

[0009] Preferably, the collision wing is made of a metal material that can be bent and reset. When the collision wing collides with the metal rod, the metal rod can be bent, and after the collision is completed, it can reset to its initial state.

[0010] Preferably, the center of mass of the eccentric wheel is positioned to one side away from the axis of the central rotating column.

[0011] Preferably, the motion support mechanism further includes a lower U-shaped cavity disposed on the concave surface of the lower U-shaped mold shell. The closed chamber formed by the upper cover plate, the U-shaped sealing structure, the right-angle sealing structure, and the lower U-shaped mold shell is used for cement concrete shaping. The lower U-shaped mold shell has a lower fixing ear adapted to the upper fixing ear at its edge. A top connecting plate is installed on each of the symmetrical sides of the lower U-shaped mold shell. A support base is placed directly below the top connecting plate. A helical spring is fixedly installed on the opposite end faces of the top connecting plate and the support base. A first belt mounting groove is provided at the center of the opposite end faces of the top connecting plate and the support base.

[0016] Compared with the prior art, the present invention provides a high-standard farmland water-saving channel in-situ casting device, which has the following beneficial effects:

[0017] 1. It can generate high-frequency vibration during the pouring of cement concrete. This vibration can accelerate the aggregation of cement concrete, thereby improving the efficiency of block formation. On the other hand, it can reduce the gaps between cement concrete to expel internal gas and improve the hardness of the U-shaped cement pipe after molding.

[0018] 2. Equipped with a vibratory casting mechanism, this system uses a dual excitation source of "collision vibration + eccentric shaking" to fundamentally reconstruct the casting process. On one hand, high-frequency vibration accelerates the accumulation and aggregation of concrete particles, directly improving the efficiency of agglomeration and solving the problems of static agglomeration and slow accumulation in existing devices. On the other hand, vibration forces the gas between particles to be discharged upwards and the gaps to close, preventing honeycomb formation inside the formed block, thereby significantly improving the density and hardness of the U-shaped cement pipe. At the same time, the concave U-shaped shaping cavity, formed by the integrated upper cover plate, U-shaped sealing structure, and right-angle sealing structure, has a depth that is strictly consistent with the channel thickness. Combined with the double feeding ports at the top, it ensures the sealing of the chamber, convenient feeding, and one-time accurate forming dimensions. The collision fins are made of bendable and resetting metal material, which automatically rebounds and resets after being struck, ensuring continuous high-frequency vibration without interruption.

[0019] 3. Equipped with a motion support mechanism, using a pre-tightening combination of "spring support + bandage reset," it supports the molding chamber while providing it with flexible movement and rapid reset capabilities. During vibration, the helical springs support the U-shaped mold shell while undergoing bending deformation to absorb high-frequency impacts and prevent rigid damage. The pre-stretched elastic bandages continuously apply rebound tension, accelerating equipment reset and preventing displacement accumulation and drift caused by long-term vibration, ensuring stable operation. The upper and lower fixed ears are connected by threads, ensuring positioning accuracy when the upper and lower mold shells are closed, and allowing for quick disassembly after concrete compaction to expose channels and accelerate agglomeration, significantly improving mold turnover efficiency.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1 and Figure 2 A high-standard farmland water-saving channel in-situ casting device is used to cast the cement concrete into a fluid state, which has the function of concrete forming.

[0031] To achieve a linked driving effect, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A vibration-type casting mechanism 1 needs to be set up. Its structure includes an upper U-shaped mold shell 11 that provides a top seal and has a hollow interior; a rotating impact wing 113 located within the upper U-shaped mold shell 11; an impact metal rod 115 that is adapted to the rotating impact wing 113 and generates a vibration effect; and an eccentric wheel 114 located below the impact wing 113 and capable of swaying during rotation. The rotating primary shaft 110 drives the central rotating column 112 to rotate rapidly, and the central rotating column 112 synchronously drives the impact wing 113 and the eccentric wheel 114 to rotate rapidly. The moving impact wing 113 will not collide with the adjacent impact metal rod 115. The kinetic energy generated between the two causes the impact metal rod 115 to vibrate. At the same time, the rapidly rotating eccentric wheel 114 causes it to sway. This vibration and sway will be transmitted along the impact metal rod 115 to the upper U-shaped mold shell 11. Under the dual effect, the cement concrete in the U-shaped shaping cavity 16 will accelerate the accumulation speed between particles. In addition, the gas between the particles will be discharged upward under the vibration effect, thereby improving the pouring efficiency and increasing the hardness of the cement concrete after it has solidified.

[0032] For details regarding the specific structure of the vibration-type casting mechanism 1, please refer to [link / reference]. Figure 3 and Figure 4It also includes an upper U-shaped cavity 13 disposed in the concave part of the upper U-shaped mold shell 11. The top of the upper U-shaped mold shell 11 is provided with an upper cover plate 12 integrally formed therewith. The edge of the upper cover plate 12 is provided with a right-angle sealing structure 14 integrally formed therewith. The edge of the U-shaped surface of the upper U-shaped mold shell 11 is provided with a U-shaped sealing structure 15 integrally formed therewith. The upper cover plate 12, the U-shaped sealing structure 15 and the right-angle sealing structure 14 form a concave U-shaped shape. The upper surface of the upper cover plate 12 is provided with two feeding ports 116 for feeding cement concrete into the U-shaped shaping cavity 16. The upper cover plate 12 has a shaft mounting hole 18 with openings at both ends at its center. A rotating shaft 110 is mounted on the upper cover plate 12 through the shaft mounting hole 18 via bearings. Multiple impact metal rods 115 are fixedly mounted on the bottom of the upper cover plate 12 around the rotating shaft 110. The upper U-shaped mold shell 1... A shaft mounting groove 19 is provided at the concave center of 1. A second rotating shaft 111, which can rotate, is installed in the shaft mounting groove 19 through a bearing.

The edge of the right-angle sealing structure 14 is provided with an upper fixing ear 17 that is integral with it. The depth of the U-shaped shaping cavity 16 is consistent with the thickness of the cement channel. The collision wing 113 is made of a metal material that can be bent and reset. When the collision wing 113 collides with the metal rod 115, the metal rod 115 can be bent, and after the collision wing 113 has finished colliding, it can reset to its initial state. The center of mass of the eccentric wheel 114 is located on one side away from the axis of the central rotating column 112.

[0033] To ensure mobility with support, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6A motion support mechanism 2 needs to be set up. Its structure includes a lower U-shaped mold shell 21 that is adapted to the upper U-shaped mold shell 11 and can form the cavity required by the mold, a helical spring 26 that provides elastic support for the lower U-shaped mold shell 21, and an elastic bandage 28 located at the center of the helical spring 26 that can accelerate the reset of the lower U-shaped mold shell 21. The upper fixing ear 17 and the lower fixing ear 23 are fixedly connected by threads. Then, cement concrete is poured into the closed U-shaped shaping cavity 16 through the feeding port 116 until the amount poured into the U-shaped shaping cavity 16 meets the requirements. During the vibration and shaking process, the helical spring 26 can produce the necessary bending phenomenon, and the elastic tension of the elastic bandage 28 can accelerate the reset of the equipment to play the necessary support and movement functions. After the vibration and shaking cause the concrete to be compacted, the vibration pouring mechanism 1 can be removed to expose the oriented concrete channel to the external environment to accelerate the concrete agglomeration phenomenon.

[0034] For details regarding the specific structure of the motion support mechanism 2, please refer to [link / reference]. Figure 5 and Figure 6 It also includes a lower U-shaped cavity 22 set on the concave surface of the lower U-shaped mold shell 21.

The lower U-shaped mold shell 21 is provided with a lower fixing ear 23 that is adapted to the upper fixing ear 17 at its edge. A top connecting plate 24 is installed on each of the symmetrical sides of the lower U-shaped mold shell 21. A support base 25 is placed directly below the top connecting plate 24. A helical spring 26 is fixedly installed on the opposite end face of the top connecting plate 24 and the support base 25. A first belt mounting groove 27 is provided at the center of the opposite end face of the top connecting plate 24 and the support base 25. An elastic bandage 28 is fixedly installed between the two corresponding first belt mounting grooves 27. The helical spring 26 is in a compressed state in the initial working state, and the elastic bandage 28 is in a stretched state.

[0035] To achieve a soft-start drive effect and reduce the negative impact of kinetic energy on the drive motor 34, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 7 and Figure 8A soft start mechanism 3 needs to be set up. Its structure includes a lower rotating disk 36 that can drive the first rotating shaft 110 to rotate, an upper rotating disk 35 located directly above the lower rotating disk 36 and capable of rotation, a soft start belt 310 that enables the lower rotating disk 36 to rotate with the upper rotating disk 35, and a drive motor 34 that can drive the upper rotating disk 35 to rotate. When the drive motor 34 is started, its rotor drives the upper rotating disk 35 to rotate rapidly. The rotating upper rotating disk 35 drives the three soft start belts 310 to rotate until the soft start belts 310 drive the lower rotating disk 36 to rotate, so as to achieve soft start. During equipment vibration, the soft start belts 310 can reduce the transmission of eccentric force to reduce the degree of damage to the rotor by radial force.

[0036] For details regarding the specific structure of the soft-start mechanism 3, please refer to [link / reference]. Figure 7 and Figure 8 It also includes a motor mounting base 31 for fixing the drive motor 34. A longitudinal support rod 32 is fixedly installed at the bottom of the motor mounting base 31. A bottom connecting plate 33 is fixedly installed on the upper surface of the upper cover plate 12 at the bottom of the longitudinal support rod 32. An upper rotating disk 35 that rotates with the drive motor 34 is fixedly installed at the rotor end. A shaft fixing groove 37 for fixing the first rotating shaft 110 is provided at the bottom end of the lower rotating disk 36. Three second belt mounting grooves 38 in a ring array are provided at the bottom edge of the upper rotating disk 35. Three third belt mounting grooves 39 in a ring array are provided at the bottom edge of the lower rotating disk 36. A soft starter belt 310 is installed between the corresponding second and third belt mounting grooves 38 and the third belt mounting groove 39. The distance between the upper rotating disk 35 and the lower rotating disk 36 is less than the length of the soft starter belt 310.

[0037] In use, the upper fixing ear 17 and the lower fixing ear 23 are fixedly connected by threads. Then, cement concrete is poured into the closed U-shaped shaping cavity 16 through the feeding port 116 until the amount poured into the U-shaped shaping cavity 16 meets the requirements. The drive motor 34 is started, and its rotor drives the upper rotating disk 35 to rotate quickly. The rotating upper rotating disk 35 drives the three soft start belts 310 to rotate until the soft start belts 310 drive the lower rotating disk 36 to rotate.

[0038] The rotating shaft 110 drives the central rotating column 112 to rotate rapidly, and the central rotating column 112 will simultaneously drive the collision wing 113 and the eccentric wheel 114 to rotate rapidly. The rotating collision wing 113 will not collide with the adjacent impact metal rod 115. The kinetic energy generated between the two causes the impact metal rod 115 to vibrate. At the same time, the rapidly rotating eccentric wheel 114 causes it to sway. This vibration and sway will be transmitted along the impact metal rod 115 to the upper U-shaped mold shell 11. Under the dual effect, the cement concrete in the U-shaped shaping cavity 16 will accelerate the accumulation speed between particles. In addition, the gas between particles will be discharged upward under the vibration effect, thereby improving the pouring efficiency and increasing the hardness of the cement concrete after it is formed.

[0039] Once the vibration and shaking have compacted the concrete, the vibratory pouring mechanism 1 can be removed, exposing the oriented concrete channel to the external environment to accelerate the concrete clumping phenomenon.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
