Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of concrete production-related equipment, and more specifically, to a concrete mixing plant material feeding structure. Background Technology

[0002] In the production process of a concrete mixing plant, the feeding structure is a crucial link in material transportation, and its stability and ease of cleaning directly affect production efficiency and equipment maintenance costs. However, the feeding structures of traditional concrete mixing plants generally suffer from problems such as easy material spillage and difficulty in flushing and cleaning. This not only leads to material waste and a dirty production environment, but also increases the difficulty and cost of equipment maintenance.

[0003] Existing material feeding structures often employ simple funnel or pipe designs, lacking effective spill prevention measures. When concrete material is conveyed downwards from the mixing tank, it easily overflows from the discharge port due to excessive feeding speed or material accumulation, especially when conveying concrete with a high slump. Overflowing material not only contaminates the production site but can also clog the discharge port, affecting the conveying of subsequent materials and even causing equipment malfunctions. For example, in some mixing plants, overflowing concrete material accumulates around the feeding structure, requiring manual cleaning and potentially hardening over time, increasing the difficulty of cleanup.

[0004] Meanwhile, the design of traditional material feeding structures is not conducive to daily flushing and cleaning. Due to the unreasonable structural design, flushing water cannot reach all corners of the feeding structure, leading to material residue accumulation, affecting the accuracy of feeding and the service life of the equipment. Especially when changing concrete types or during long-term shutdowns, a thorough cleaning of the feeding structure is required. Traditional structures often require disassembling multiple parts, which is time-consuming and labor-intensive, seriously affecting production efficiency. In addition, residual material may also cause concrete quality problems, such as the mixing of different types of concrete, affecting the performance of the concrete.

[0005] With the increasing automation of concrete production and the increasingly stringent environmental protection requirements, it is no longer possible to meet the needs of modern production. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a material feeding structure for a concrete batching plant, which solves the problems of easy material overflow and inconvenience in flushing and cleaning that are common in the material feeding structures of traditional concrete batching plants in the prior art. This not only leads to material waste and a dirty production environment, but also increases the difficulty and cost of equipment maintenance.

[0007] According to one aspect, at least one embodiment of the present disclosure provides a concrete mixing plant feeding structure, comprising:

[0008] The package includes an outer cover, a dispensing tank, and an inlet pipe, wherein the dispensing tank is mounted on the outer cover and the inlet pipe is connected to the outer surface of the dispensing tank.

[0009] A feeding control component is disposed between the dispensing tank and the outer cover;

[0010] A boss and a cleaning assembly, wherein the boss is disposed at the bottom inside the outer cover and the cleaning assembly is disposed at the bottom inside the outer cover;

[0011] The feeding control component includes a pair of fixed rods, which are fixed to opposite ends of the outer wall of the dispensing tank. One end of each fixed rod is rotatably connected to a first hydraulic cylinder via a pin. Both ends of the bottom of the dispensing tank are rotatably connected to a sealing cover via a pin. The sealing cover is rotatably connected to the output end of the first hydraulic cylinder via a pin.

[0012] As a further technical solution, a movable cavity is provided inside the surface of the outer cover, and a second hydraulic cylinder is installed at both ends of the movable cavity. The output end of the second hydraulic cylinder is connected to a lifting seat, and the dispensing tank is fixed on the lifting seat.

[0013] As a further technical solution, the cleaning component includes a pair of collection chambers, which are opened at both ends of the bottom of the outer cover. Several drainage grooves are opened at both ends of the inner bottom surface of the outer cover, and the drainage grooves are connected to the collection chambers.

[0014] As a further technical solution, a long groove is provided between the boss and the outer cover, and a third hydraulic cylinder is provided on the inner surface of the outer cover and the bottom surface of the long groove. A long plate is provided at the output end of the third hydraulic cylinder.

[0015] As a further technical solution, the long plate is located inside the long groove, and a pipe is fixedly connected to the bottom of the long plate. Several water spray holes are opened on both ends of the pipe, and the long plate is sealed and fitted to the inner wall of the long groove.

[0016] As a further technical solution, the pair of sealing covers have a conical structure.

[0017] As a further technical solution, a drive motor is provided at the bottom of the distribution tank, and an agitator is provided at the output end of the drive motor.

[0018] As a further technical solution, the surface of the boss is an inclined structural surface, and both ends of the boss surface are inclined toward the drainage groove.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. In this disclosure, the feeding control component drives the sealing cover to rotate via the first hydraulic cylinder, thereby controlling the opening and closing of the material dispensing port of the dispensing tank. When the conical sealing cover is closed, it fits against the bottom of the dispensing tank to cut off the discharge. When it is open, it accurately releases the concrete, preventing material overflow during dispensing. The second hydraulic cylinder drives the lifting seat to adjust the height of the dispensing tank to adapt to different transportation equipment. The fixed rod provides support for the first hydraulic cylinder to ensure the stable operation of the sealing cover. The drive motor and the agitator continuously agitate the concrete in the dispensing tank to prevent accumulation and blockage, solving the problems of easy overflow and unstable dispensing in traditional dispensing structures, and improving the stability and accuracy of dispensing.

[0021] 2. In this disclosure, the cleaning component uses a third hydraulic cylinder to drive the long plate to move back and forth in the long groove. The water spray holes at the bottom of the long plate spray high-pressure water outward to flush the inner wall of the outer cover, the surface of the boss, and the residual concrete in the long groove. The inclined surface of the boss causes the residual concrete to flow with the water into the drainage trough. The sewage flows into the collection chamber at the bottom of the outer cover through the drainage trough. The long plate and the inner wall of the long groove are sealed to prevent water leakage. The collection chamber facilitates the centralized treatment of sewage and concrete residue. The flushing and cleaning can be completed without disassembling the parts, which solves the problems of inconvenient flushing and difficult cleaning of traditional material feeding structures, keeps the material feeding structure clean, and reduces maintenance difficulty and cost.

[0036] like Figures 1-6 As shown, it illustrates a concrete mixing plant feeding structure according to an embodiment of the present disclosure, including:

[0037] The package includes an outer cover 1, a material distribution tank 2, and an inlet pipe 3. The material distribution tank 2 is mounted on the outer cover 1, and the inlet pipe 3 is connected to the outer surface of the material distribution tank 2.

[0038] Feeding control component 5, wherein the feeding control component 5 is disposed between the dispensing tank 2 and the outer cover 1;

[0039] The boss 4 and the cleaning component 6 are provided inside the bottom of the outer cover 1.

[0040] The feeding control component 5 includes a pair of fixed rods 5-1, which are fixed to opposite ends of the outer wall of the dispensing tank 2. One end of the fixed rod 5-1 is rotatably connected to a first hydraulic cylinder 5-2 via a pin. Both ends of the bottom of the dispensing tank 2 are rotatably connected to a sealing cover 5-3 via pins. The sealing cover 5-3 is rotatably connected to the output end of the first hydraulic cylinder 5-2 via a pin. A movable cavity 5-4 is opened in the surface of the outer cover 1. A second hydraulic cylinder 5-5 is installed at both ends of the movable cavity 5-4. The output end of the second hydraulic cylinder 5-5 is connected to a lifting seat 5-6. The dispensing tank 2 is fixed on the lifting seat 5-6.

[0041] In some examples, during the material feeding process at a concrete mixing plant, a feeding control component 5 is designed to achieve precise control over the concrete discharge and discharge height. This component is based on a pair of fixed rods 5-1 fixed at opposite ends of the outer wall of the distribution tank 2. One end of the fixed rod 5-1 is rotatably connected to the first hydraulic cylinder 5-2 via a pin, providing a power fulcrum for the opening and closing of the sealing cover 5-3. The bottom ends of the distribution tank 2 are also rotatably connected to the sealing cover 5-3 via pins, and the sealing cover 5-3 is connected to the output end of the first hydraulic cylinder 5-2. When the piston rod of the first hydraulic cylinder 5-2 extends, it can drive the sealing cover 5-3 to rotate around the pin, so that it fits against the bottom of the distribution tank 2 to form a seal and block the concrete discharge; when the piston rod retracts, the sealing cover 5-3 opens, releasing the discharge channel.

[0042] A second hydraulic cylinder 5-5 is installed inside the movable cavity 5-4 on the surface of the outer cover 1. Its output end is connected to the lifting seat 5-6, and the material distribution tank 2 is fixed on the lifting seat 5-6, forming a height adjustment mechanism. When the second hydraulic cylinder 5-5 is activated, it can drive the lifting seat 5-6 to move up and down, thereby driving the material distribution tank 2 to rise and fall as a whole, thus adjusting the discharge height of concrete to adapt to different height transportation equipment or pouring needs.

[0043] The concrete discharge switch function is realized by controlling the opening and closing of the sealing cover 5-3 through the first hydraulic cylinder 5-2. The discharge height is adjusted by the cooperation of the second hydraulic cylinder 5-5 and the lifting seat 5-6. The feeding control component 5 provides efficient and precise operation guarantee for the concrete mixing plant's feeding process.

[0044] like Figures 1-6 As shown in the figure, the cleaning component 6 in this embodiment includes a pair of collection chambers 6-1. The collection chambers 6-1 are opened at both ends of the bottom of the outer cover 1. Several drainage grooves 6-2 are opened at both ends of the inner bottom surface of the outer cover 1. The drainage grooves 6-2 are connected to the collection chambers 6-1. A long groove 6-3 is opened between the boss 4 and the outer cover 1. A third hydraulic cylinder 6-4 is provided on the inner surface of the outer cover 1 and the inner bottom surface of the long groove 6-3. A long plate 6-5 is provided at the output end of the third hydraulic cylinder 6-4. The long plate 6-5 is located in the long groove 6-3. A pipe 6-6 is fixedly connected to the bottom of the long plate 6-5. Several water spray holes 6-7 are opened on both ends of the pipe 6-6. The long plate 6-5 is sealed and fitted to the inner wall of the long groove 6-3.

[0045] In some examples, a cleaning component 6 is designed to promptly clean up scattered concrete in the outer casing 1 and keep the material unloading structure clean. This component is centered on the collection chambers 6-1 at both ends of the bottom of the outer casing 1, which are connected to the drainage channels 6-2 at both ends of the inner bottom surface of the outer casing 1, forming a sewage collection channel. A third hydraulic cylinder 6-4 is arranged in the long groove 6-3 between the boss 4 and the outer casing 1. Its output end is connected to a long plate 6-5. Water spray holes 6-7 are opened on both sides of the pipe 6-6 fixed at the bottom of the long plate 6-5, forming a flushing system. The water spray holes 6-7 can spray water onto both sides of the boss 4 for flushing. When the third hydraulic cylinder 6-4 is activated, it drives the long plate 6-5 to move back and forth along the long groove 6-3. The high-pressure water flow in the pipe 6-6 is sprayed outward through the water spray holes 6-7, powerfully flushing the inner wall of the outer casing 1, the surface of the boss 4, and the residual concrete in the long groove 6-3.

[0046] The inner walls of the long plate 6-5 and the long trough 6-3 are designed to be sealed to prevent water leakage and ensure effective flushing. The flushed wastewater, carrying concrete residue, flows into the collection chamber 6-1 through the drainage trough 6-2. The collection chamber 6-1 can be further equipped with a filter screen or other filtration device to separate impurities. Through the reciprocating motion of the long plate 6-5 driven by the third hydraulic cylinder 6-4, the flushing action of the high-pressure water flow from the spray holes 6-7, and the wastewater collection design of the drainage trough 6-2 and collection chamber 6-1, the cleaning component 6 effectively removes scattered concrete inside the outer casing 1, maintaining the cleanliness and smooth operation of the material feeding structure.

[0047] For example, such as Figure 2 As shown, the pair of sealing covers 5-3 have a conical structure.

[0048] In some examples, the conical structure allows the two sealing covers 5-3 to quickly adhere and cut off the material discharge after being closed, making it easier to control the precise material discharge when opened next.

[0049] For example, such as Figure 3 As shown, a drive motor 7 is provided at the bottom of the distribution tank 2, and an agitator 8 is provided at the output end of the drive motor 7.

[0050] In some examples, by providing a drive motor 7 and an agitator 8, the inside of the feed tank can be continuously agitated to prevent concrete from accumulating and clogging inside.

[0051] For example, such as Figure 2 As shown, the surface of the boss 4 is an inclined structural surface, and both ends of the surface of the boss 4 are inclined toward the drainage groove 6-2.

[0052] In some examples, by tilting the structural surface, the surface residue is reduced, making it easier to rinse clean.

[0053] In actual use: the outer cover 1 is fixed, the dispensing tank 2 is connected to the output end of the second hydraulic cylinder 5-5 inside the outer cover 1 via the lifting seat 5-6, the fixing rod 5-1 is fixed to the outer wall of the dispensing tank 2, one end of the first hydraulic cylinder 5-2 is rotatably connected to the fixing rod 5-1 and the other end is rotatably connected to the sealing cover 5-3, the sealing cover 5-3 is rotatably connected to the bottom of the dispensing tank 2, the boss 4 is set at the bottom inside the outer cover 1, the collection chamber 6-1 of the cleaning component 6 is opened at both ends of the bottom of the outer cover 1, the drainage trough 6-2 communicates with the collection chamber 6-1, the long groove 6-3 is opened between the boss 4 and the outer cover 1, and the third hydraulic cylinder 6-4 is set in the outer cover 1. The inner side and the bottom surface of the long trough 6-3 are connected to the output end of the long plate 6-5 and the third hydraulic cylinder 6-4. The pipe 6-6 is fixed to the bottom of the long plate 6-5. The water spray hole 6-7 is opened on both sides of the pipe 6-6. The pipe 3 is connected to the material distribution tank 2. The drive motor 7 is installed at the bottom of the material distribution tank 2 and its output end is connected to the agitator 8. When in use, the second hydraulic cylinder 5-5 adjusts the height of the material distribution tank 2, the first hydraulic cylinder 5-2 controls the opening and closing of the sealing cover 5-3, and the drive motor 7 drives the agitator 8 to prevent concrete accumulation. The water spray hole 6-7 of the pipe 6-6 sprays water to flush the outer cover 1 and the boss 4. The sewage flows into the collection chamber 6-1 through the drainage trough 6-2.
