Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to a concrete feeding and hoisting machine. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone material made by mixing cementitious materials, granular aggregates (also known as aggregates), water, and, if necessary, admixtures and additives in a certain proportion, uniformly mixing, compacting, and curing.

[0003] When concrete is being mixed at a batching plant, an inclined track frame is erected between the ground and the batching plant. The material is manually poured into a hopper and then transported by the track frame to the top of the batching plant for dumping. However, the overall material feeding equipment is bulky and inconvenient to set up quickly. In addition, manual material feeding is inefficient. Therefore, a concrete feeding hoist is proposed to solve this technical defect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a concrete feeding and hoisting machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete feeding hoist, including a support base, a clamping seat on the support base, a clamping assembly on the clamping seat, a hydraulic push rod on the side of the support base, a mounting seat at the push rod of the hydraulic push rod, a pair of telescopic rods on the mounting seat, a connecting seat between the other ends of the telescopic rods, a lifting hopper through which the telescopic rods pass through the inner wall of the connecting seat, a pull rope passing through the top of the telescopic rod at the bottom of the telescopic rod, and a winding assembly for winding and unwinding the pull rope on the mounting seat;

[0006] The upper end of the lifting hopper is equipped with a material receiving seat;

[0007] The lifting hopper is equipped with a switch control component that enables the opening and closing of the bottom opening of the lifting hopper.

[0008] Using the above technical solution, the clamping seat is placed on the outer edge of the upper perimeter of the mixing plant. The clamping assembly is used to fix the clamping seat on the mixing plant. At the same time, the hydraulic push rod pushes the mounting seat to move, causing the lifting bucket to move to the outside of the mixing plant. The winding assembly is used to wind and unwind the pull rope. Under the telescopic support of the telescopic rod, the traction connecting seat and the lifting bucket move synchronously, so that the lifting bucket moves horizontally and vertically. The receiving seat on the lifting bucket moves to the discharge port of the storage silo for automatic feeding. After feeding is completed, the lifting bucket moves horizontally and vertically, so that the lower end of the lifting bucket moves above the feeding port of the mixing plant. With the opening of the switch control assembly, the material can be unloaded into the mixing plant.

[0009] As a preferred embodiment of the present invention, the clamping assembly includes a second hydraulic push rod disposed at the upper end of the clamping seat, and a clamping block located within the clamping seat is provided at the push rod of the second hydraulic push rod.

[0010] Using the above technical solution, the hydraulic push rod 2 pushes the clamping block downward to achieve clamping and fixing.

[0011] As a preferred embodiment of this utility model, a plurality of telescopic rods are provided between the mounting base and the support base.

[0012] By adopting the above technical solution, the telescopic support of the second telescopic rod ensures the stability of the moving mounting base.

[0013] As a preferred technical solution of this utility model, the winding assembly includes connecting seats on the left and right sides of the upper end of the mounting base. A servo motor is provided on the outer side of one of the connecting seats. The output end of the servo motor is provided with a rotating shaft that rotates with the outside of the other connecting seat. A pair of winding discs are provided on the outside of the rotating shaft. The pull rope is wound and fixed to the outside of the winding disc.

[0014] Using the above technical solution, the servo motor on the connecting seat drives the rotating shaft and the winding disc to rotate synchronously, thereby realizing the winding and unwinding of the winding disc.

[0015] As a preferred embodiment of this utility model, the bottom wall of the receiving seat is inclined downward at a 30-degree angle from the outside towards the side facing the lifting hopper.

[0016] Using the above technical solution, the material is fed onto the receiving seat and discharged into the lifting hopper along the inclined surface.

[0017] As a preferred embodiment of this utility model, the switch control assembly includes a hydraulic push rod three located on the opposite side of the lower end of the connecting seat, and the push rod of the hydraulic push rod three is provided with a switch plate that fits against the lower surface of the lifting hopper.

[0018] As a preferred technical solution of this utility model, when the switch plates are attached to each other, they form a cylinder to seal the opening on the lower surface of the lifting hopper.

[0019] Using the above technical solution, the hydraulic push rod operates to move the switch plate, so that the switch plate can be closed to seal the opening on the lower surface of the lifting hopper, and the switch plate can be separated to open the opening for material discharge.

[0020] As a preferred embodiment of this utility model, the bottom of the support base is provided with a plurality of mounting holes.

[0021] Using the above technical solution, when the clamping seat cannot be installed on the outer edge of the mixing plant, the support seat can be fixed on the mixing plant by passing the fastening screw through the mounting hole.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This concrete feeding hoist is positioned on the outer edge of the upper part of the mixing plant using a clamping base. The clamping assembly secures the base to the mixing plant. Simultaneously, a hydraulic push rod moves the mounting base, shifting the lifting bucket to the outside of the mixing plant. A winding assembly then rewinds and unwinds the pull rope. With the support of a telescopic rod, the traction connecting seat and the lifting bucket move synchronously, causing the lifting bucket to move laterally and vertically. This moves the receiving seat on the lifting bucket to the discharge port of the storage silo for automatic feeding. After feeding, the lifting bucket moves laterally and vertically again, moving its lower end above the mixing plant's feed inlet. A switch control assembly then opens, allowing the material to be unloaded into the mixing plant. Compared to existing technologies, this hoist improves the ease of installation and placement, and achieves automatic material replenishment. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 3 The concrete feeding hoist in this embodiment mainly includes a support base 1, a clamping base 3, a lifting hopper 10, a hydraulic drive assembly, a winding assembly, a switch control assembly, and other parts. Through the coordinated work of each component, the automatic feeding and unloading of concrete materials is realized, which improves the convenience of equipment construction and placement, as well as the feeding efficiency.

[0030] The support base 1 serves as the foundation for the entire equipment. Multiple mounting holes 2 are provided at its bottom. When the clamping base 3 cannot be installed on the outer edge of the mixing station, the support base 1 can be firmly fixed to a suitable position on the mixing station by passing the fastening screws through the mounting holes 2, thus ensuring the overall stability of the equipment.

[0031] The clamping seat 3 is fixed on the left side surface of the support seat 1 and is used to place it outside the upper outer edge of the mixing station.

[0032] The clamping seat 3 is equipped with a clamping assembly, which includes a hydraulic push rod 4 fixed to the upper surface of the clamping seat 3. A clamping block 5 located inside the clamping seat 3 is fixed at the push rod of the hydraulic push rod 4. When it is necessary to fix the clamping seat 3, the hydraulic push rod 4 is activated, which pushes the clamping block 5 to move down, so that the clamping block 5 tightly abuts against the outer edge of the mixing station, thereby realizing the clamping and fixing work and ensuring that the equipment will not shake or shift during operation.

[0033] Hydraulic drive components;

[0034] A hydraulic push rod 6 is fixed on the right side of the support base 1. A mounting base 7 is fixed at the push rod of the hydraulic push rod 6. The hydraulic push rod 6 is made of high-strength alloy steel and has good compressive and tensile strength, and can withstand large working loads.

[0035] Multiple telescopic rods 19 are fixed between the mounting base 7 and the support base 1. The telescopic rods 19 are made of stainless steel, which has good corrosion resistance and telescopic stability. In this embodiment, there is a pair of telescopic rods 19, which are symmetrically distributed front and back. The telescopic support function of the telescopic rods 19 ensures that the mounting base 7 can remain stable when it moves under the push of the hydraulic push rod 6, without any deviation or shaking, thus improving the reliability of the equipment operation.

[0036] The bottom of the mounting base 7 is fixed with a pair of telescopic rods 8 that are symmetrically distributed on the left and right. The telescopic rods 8 are also made of stainless steel. The other end of the rods 8 is fixed with a connecting seat 9. The inner wall of the connecting seat 9 is fixed with a lifting hopper 10 that is passed through by the telescopic rods 8. The lifting hopper 10 is made of high-strength plastic or metal, and has a certain strength and wear resistance, and can withstand the weight and friction of concrete materials.

[0037] The bottom of the telescopic pole 8 is fixed with a pull rope 15 that passes through the top of the telescopic pole 8. The pull rope 15 is made of high-strength steel wire rope, which has high tensile strength and flexibility. The mounting base 7 is equipped with a winding assembly for winding and unwinding the pull rope 15.

[0038] A receiving seat 16 is fixed on the upper left side surface of the lifting hopper 10. The bottom wall of the receiving seat 16 is inclined downward at a 30-degree angle from the outside towards the side facing the lifting hopper 10. This inclined design allows the material to be smoothly discharged into the lifting hopper 10 along the inclined surface when it is fed onto the receiving seat 16, thus avoiding the accumulation of material on the receiving seat 16.

[0039] The winding assembly includes connecting seats 11 fixed to the left and right sides of the upper surface of the mounting base 7. A servo motor 12 is fixed to the right side surface of the right connecting seat 11. The servo motor 12 is a high-performance AC servo motor with advantages such as high control precision and fast response speed. The output end of the servo motor 12 is fixed to a rotating shaft 13 that rotates with the right side of the left connecting seat 11. The rotating shaft 13 is made of high-strength alloy steel and has good torsional rigidity. A pair of winding discs 14 are fixed to the outside of the rotating shaft 13 in a concentric circle. The winding discs 14 are made of metal and have a special surface treatment, which has good wear resistance. The pull rope 15 is wound and fixed to the outside of the winding discs 14. When it is necessary to lift or lower the lifting hopper 10, the servo motor 12 is started, which drives the rotating shaft 13 and the winding discs 14 to rotate synchronously, thereby realizing the winding and unwinding of the pull rope 15, and thus controlling the lifting of the lifting hopper 10.

[0040] The lifting hopper 10 is equipped with a switch control assembly for opening and closing the bottom opening of the lifting hopper 10. The switch control assembly includes a hydraulic push rod 3 17 fixed to the left and right sides of the lower surface of the connecting seat 9. The hydraulic push rod 3 17 uses hydraulic components of the same material and performance as the hydraulic push rod 1 6 and the hydraulic push rod 2 4. A switch plate 18 is fixed at the push rod of the hydraulic push rod 3 17 and fits against the lower surface of the lifting hopper 10. When the switch plates 18 are fitted together, they form a cylinder to seal the opening of the lower surface of the lifting hopper 10 and prevent material leakage during the lifting process. When unloading is required, the hydraulic push rod 3 17 is activated to make it work and move the switch plate 18. The switch plate 18 separates to open the opening and discharge the material into the mixing plant.

[0041] Structural design principles and usage steps:

[0042] Place the support base 1 in a suitable position near the mixing plant. If the clamping base 3 can be installed on the outer edge of the upper part of the mixing plant, push the clamping block 5 down by the hydraulic push rod 4 to fix the clamping base 3 on the mixing plant. If the clamping base 3 cannot be installed, fix the support base 1 on the mixing plant by passing the fastening screw through the mounting hole 2.

[0043] Start the hydraulic push rod 6 to push the mounting base 7 to move. With the support of the telescopic rod 19, the mounting base 7 moves smoothly, thereby moving the lifting hopper 10 to the outside of the mixing plant.

[0044] Start the servo motor 12, and release the pull rope 15 through the rotating shaft 13 and the winding disc 14. Under the telescopic support of the telescopic rod 8, the traction connecting seat 9 and the lifting bucket 10 descend synchronously, so that the receiving seat 16 on the lifting bucket 10 moves to below the discharge port of the storage bin.

[0045] The storage silo begins to discharge material, which falls onto the receiving seat 16 and is discharged into the lifting hopper 10 along the inclined bottom wall of the receiving seat 16.

[0046] After the material is fed, the servo motor 12 is started to rotate in reverse to wind up the pull rope 15. With the support of the telescopic rod 8, the lifting bucket 10 rises. At the same time, the hydraulic push rod 6 can work together to make the lifting bucket 10 move laterally, moving the lower end of the lifting bucket 10 above the feeding port of the mixing plant.

[0047] Start the hydraulic push rod 17 to open the switch plate 18, open the lower surface opening of the lifting hopper 10, and unload the material into the mixing station, completing one feeding and unloading process.

[0048] To improve the automation level and ease of operation of the equipment, a control system can be installed. The control system uses a programmable logic controller (PLC) as the core control unit.

[0049] Through the detailed structural and positional connections, structural scheme principles and usage steps, and system control expansion described above, the concrete feeding and unloading machine of this utility model can achieve efficient and stable concrete material feeding and unloading operations, and has high practical value and market application prospects.

[0050] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
