Description
Technical Field
[0001] The utility model belongs to the field of building construction, and more specifically relates to a concrete mixing device which is convenient for loading materials. Background Art
[0002] The field of building construction technology is at the core of the construction industry, encompassing the entire process from planning to completion. Concrete processing is a crucial step, accomplished through concrete mixing equipment. This equipment, including concrete mixer trucks and mixing plants, efficiently mixes raw materials such as cement, aggregates, and sand to ensure the uniformity and quality of concrete. With technological advancements, modern concrete mixing equipment is constantly being updated, incorporating automated control systems and intelligent operations to improve production efficiency and product quality. At the same time, the application of new materials and construction techniques is also driving the development of concrete processing technology. For example, self-healing concrete and ultra-high performance concrete offer new solutions for the durability and safety of building structures. Continuous innovation and development in the field of building construction technology is driving the construction industry towards greater efficiency, environmental friendliness, and safety.
[0003] Concrete mixing equipment typically includes key components such as the mixing system, water supply system, transmission system, control system, and feeding system. The mixing system is the most critical component, comprising the mixing drum, mixing blades, and mixing motor, responsible for thoroughly mixing raw materials such as cement, aggregate, sand, and water. The water supply system controls the water-cement ratio of concrete to ensure its quality. The transmission system provides power to drive the mixing drum. The control system monitors and regulates the equipment's operating status to ensure a safe and stable construction process. The feeding system, including hoppers, conveyor belts, or elevators, is used to feed raw materials into the mixing drum. These components work together to achieve efficient mixing and accurate proportioning of concrete, ensuring the quality and progress of construction.
[0004] The feeding system of conventional concrete mixing equipment typically consists of a lifting cylinder, a lifting rod, and a hopper. The lifting rod is subject to a certain degree of pressure and distortion during use, and is particularly susceptible to deformation under prolonged, frequent use or overload. When the lifting rod is deformed, the lifting cylinder cannot lift the hopper to the feed inlet and allow the material to enter the mixing drum smoothly. This requires replacing the lifting rod, a cumbersome process that increases maintenance costs. During this lifting process, concrete can also enter the lifting cylinder, causing jamming and disrupting the feeding process. Utility Model Content
[0005] The main purpose of this application is to provide a concrete mixing equipment that is easy to load. The pulley group and the wire rope cooperate with each other to replace the existing lifting rod, thereby improving the smoothness of the entire loading process and facilitating loading. When the wire rope breaks, the wire rope can be replaced at any time, reducing maintenance costs.
[0006] In order to achieve the above objectives, the present application proposes a concrete mixing device that is convenient for loading, comprising:
[0007] The bracket is mounted on the outer end of the stirring system and forms an acute angle with the stirring system;
[0008] The hopper can slide along the inclined surface formed by the support and the stirring system to the feed port of the stirring system;
[0009] A driving member is provided on the bracket and is capable of generating a driving force, wherein a steel wire rope is wound around one end of the driving member;
[0010] The pulley block is mounted on the bracket, and one end of the steel wire rope is fixedly connected to the hopper through the pulley block.
[0011] Because the bracket and the mixing system are at an angle, it acts like a slope. The drive generates a driving force that drives the wire rope to retract and release. When the wire rope is released, the pulley set allows the hopper to move along the bracket's tilt toward the material on the ground until it contacts the ground. At this point, construction workers can easily add materials directly into the hopper. When the hopper is full, the drive is reversed to tighten the wire rope, which in turn drives the hopper along the slope formed by the bracket toward the mixing system's feed port until the bottom of the hopper aligns with the feed port. The material in the hopper is then released until the material enters the feed port.
[0012] In some embodiments, the hopper is provided with a first running wheel, the bracket is provided with a running surface on a side opposite to the first running wheel, the first running wheel is provided with a friction surface, the friction surface is placed on the running surface and slides relative to the running surface.
[0013] The first running wheel slides on the running surface, so that the movement of the hopper on the bracket is more labor-saving, thereby reducing damage to the driving component.
[0014] In some embodiments, a rack is provided on the running surface, a limiting end is provided on the first running wheel adjacent to the friction surface, and the running surface is placed between the limiting ends.
[0015] Through the design of the rack, the friction between the friction surface of the first running wheel and the running surface can be increased, and the friction will not cause excessive burden on the driving part. Due to the increased friction, the running wheel can be prevented from spinning idly due to no load, thereby effectively avoiding the wear of the running wheel on the bracket.
[0016] In some embodiments, a sliding groove is relatively provided on the bracket, and a second running wheel is provided on the hopper. The second running wheel is placed in the sliding groove and moves along the direction in which the sliding groove extends.
[0017] Through the mutual cooperation of the first running wheel and the second running wheel, it can be ensured that the hopper runs stably on the bracket and the first running wheel is prevented from receiving excessive pressure.
[0018] In some embodiments, the hopper comprises:
[0019] The bell mouth has a guide plate installed at its maximum diameter mouth;
[0020] A leak-proof box, which is fixedly connected to the smallest diameter opening of the bell mouth, and a leak-proof component is provided in the leak-proof box;
[0021] The feed box is hinged to the leak-proof box and can correspond to the feed port, and is used to guide the material into the feed port of the mixing system.
[0022] The guide plate can smoothly guide the material near the bell mouth into the bell mouth, and when the hopper crawls on the bracket, it can ensure that the material in the bell mouth will not be shaken out due to bumps, thereby improving the stability of the overall equipment.
[0023] In some embodiments, the guide plate comprises:
[0024] The baffle is fixed to the edge of the bell mouth and is arranged along the feeding direction of the bell mouth;
[0025] The ribs are arranged at both ends of the baffle, and arc angles are provided at the joints with the baffle. The ribs are triangular in shape.
[0026] On the one hand, the triangular ribs enhance the stability of the baffle, and on the other hand, they form an open guide with the baffle, which can smoothly guide the materials into the bell mouth without interfering with the operation of the construction workers.
[0027] In some embodiments, the anti-leakage component comprises:
[0028] A driving plate is fixed with a slider, and an inlet and an outlet are provided at one end of the leak-proof box facing the feed box, and the driving plate can move along the inlet and outlet directions;
[0029] The first driving motor is fixedly installed in the leak-proof box. The output end of the first driving motor is fixedly connected to a screw rod, and the sliding block is placed on the screw rod for sliding.
[0030] By starting the first drive motor, the slider on the screw rod can be driven to move, so that you can control the movement of the drive plate away from the inlet and outlet of the feed box, thereby opening a channel for material outflow.
[0031] In some embodiments, the driving member includes:
[0032] A second driving motor is mounted on the bracket;
[0033] A winch, which is fixedly connected to the output shaft of the drive motor;
[0034] The steel wire rope is wound on a winch.
[0035] The utility model provides a concrete mixing device that is convenient for loading, which has the following beneficial effects:
[0036] (1) The present invention utilizes a pulley block and a steel wire rope to cooperate with each other to replace the existing lifting rod, thereby improving the smoothness of the entire loading process and facilitating loading. When the steel wire rope breaks, the steel wire rope can be replaced at any time, thereby reducing maintenance costs.
[0037] (2) By providing the first running wheel and the second running wheel in the present invention, it is possible to ensure that the hopper runs stably on the bracket and prevent the first running wheel from receiving excessive pressure.
[0038] (3) By arranging a rack on the running surface of the bracket according to the present invention, the friction between the friction surface of the first running wheel and the running surface can be increased, while the friction will not cause excessive burden on the driving member. Due to the increased friction, the idling of the running wheel due to no load can be avoided, thereby effectively avoiding the wear of the running wheel on the bracket.

[0051] Example
[0052] The feeding system of conventional concrete mixing equipment typically consists of a lifting cylinder, a lifting rod, and a hopper. The lifting rod is subject to a certain degree of pressure and distortion during use, and is particularly susceptible to deformation under prolonged, frequent use or overload. When the lifting rod is deformed, the lifting cylinder cannot lift the hopper to the feed inlet and allow the material to enter the mixing drum smoothly. This requires replacing the lifting rod, a cumbersome process that increases maintenance costs. During this lifting process, concrete can also enter the lifting cylinder, causing jamming and disrupting the feeding process.
[0053] Based on this, in order to solve the above problems caused by the jacking structure, such as the cumbersome replacement process, easy jamming, and disadvantageous for normal loading, this embodiment provides a concrete mixing equipment that is convenient for loading. Figure 1 , including: bracket 1, hopper 2, such as Figure 2 The driving member and the pulley assembly 9 shown. Figure 2 The bracket 1 is mounted on the outer end of the stirring system 7 by means of bolts and other fasteners, and is set at an acute angle with the stirring system 7, and the acute angle can range from 15 to 30 degrees. The hopper 2 is placed on the inclined surface presented by the bracket 1, and can slide along the inclined surface presented by the bracket 1 and the stirring system 7 to the feed port of the stirring system 7. The driving member is fixedly mounted on the bracket 1 and can generate a driving force to drive the hopper 2 to move up and down along the inclined surface. A steel wire rope 3 is wound around one end of the driving member, and a pulley block 9 is passed through one end of the steel wire rope 3. The pulley block 9 is fixedly mounted on the bracket 1. The steel wire rope 3 is finally fixedly connected to the hopper 2 through the pulley block 9.
[0054] In this embodiment, since the bracket 1 and the mixing system 7 are at an angle, they are equivalent to a slope. The driving member generates a driving force to drive the wire rope 3 to be retracted and released. When the wire rope 3 is released, the pulley set 9 allows the hopper 2 to move toward the material on the ground along the tilt direction of the bracket 1 until it contacts the ground. At this time, the construction workers can easily add the material directly into the hopper 2. When the hopper 2 is full, the driving member is started in the reverse direction to tighten the wire rope 3, thereby driving the hopper 2 to move along the slope formed by the bracket 1 toward the feed port of the mixing system 7 until the bottom of the hopper 2 corresponds to the feed port. The material in the hopper 2 is then released until the material enters from the feed port.
[0055] Specifically, in some embodiments, the drive element includes: a second drive motor 4 and a capstan 5. The second drive motor 4 is fixedly mounted on the bracket 1 via a motor mount, and the output shaft of the second drive motor 4 is fixedly connected to the capstan 5 via a coupling. At this time, the steel wire is wound around the capstan 5. The second drive motor 4 of this embodiment is capable of forward and reverse rotation, adopting the motor forward and reverse rotation strategy in the prior art. That is, the purpose of reverse rotation can be achieved by simply swapping any two phases of the three-phase power supply lines connected to the second drive motor. Therefore, the theoretical knowledge of forward and reverse rotation is not detailed here.
[0056] It should be noted that the pulley assembly 9 in this embodiment refers to a fixed pulley mounted on a mounting frame, the fixed pulley can rotate relatively, and the mounting frame is fixedly mounted on the bracket 1 by fasteners such as bolts.
[0057] It should be noted that the mixing system 7 referred to in this embodiment is a vital component of the concrete mixing equipment. Its main components include a mixing drum, a mixing blade, a mixing motor and a feed port. The mixing drum is a cylindrical container, usually made of steel or special alloy, with mixing blades arranged on the inner wall, which can effectively mix raw materials such as cement, aggregate, sand and water. The mixing motor serves as a power source to drive the mixing drum to rotate, ensuring that the raw materials are fully mixed during the mixing process. The feed port is installed on the top of the mixing drum, and the raw materials are put into the channel of the mixing drum to achieve efficient mixing and accurate proportioning of concrete. Since the mixing system 7 is not the technical problem to be solved by the present invention, it will not be described here.
[0058] In some embodiments, reference Figure 3 or Figure 6The hopper 2 includes: a bell mouth 21, a leak-proof box 22, and a feed box 23. The bell mouth 21, the leak-proof box 22, and the feed box 23 are connected in sequence. Among them, a guide plate 6 is installed at the maximum diameter opening of the bell mouth 21. The guide plate 6 can smoothly guide the material located near the bell mouth 21 into the bell mouth 21, and when the hopper 2 crawls on the bracket 1, it can ensure that the material in the bell mouth 21 will not be shaken out due to bumps, thereby improving the stability of the overall equipment. The leak-proof box 22 is fixedly connected to the minimum diameter opening of the bell mouth 21, and a leak-proof component is provided in the leak-proof box 22. Among them, the leak-proof component includes: a drive plate 8 and a first drive motor. The drive plate 8 is fixed with a slider, and the leak-proof box 22 is provided with an inlet and outlet at one end facing the feed box 23, and the drive plate 8 can move along the inlet and outlet direction. The first drive motor is fixedly installed in the leak-proof box 22 through a motor box, and the output end of the first drive motor is fixedly connected to a screw rod, and the slider is placed on the screw rod and slides. By starting the first drive motor, the slider on the screw rod can be driven to move, thereby controlling the movement of the drive plate 8 away from the inlet and outlet of the feed box 23, thereby opening the channel for material outflow. In this embodiment, the feed box 23 is hinged to the leak-proof box 22 via a pin and can correspond to the feed port, used to guide the material into the feed port of the mixing system 7.
[0059] In some embodiments, reference Figure 3-6 First running wheels 13 are mounted on both ends of the leak-proof box 22 of the hopper 2 via shafts. A running surface 11 is provided on the side of the bracket 1 opposite the first running wheel 13. The first running wheel 13 is provided with a friction surface 131, which is placed on and slides relative to the running surface 11. With the first running wheel 13 sliding on the running surface 11, the movement of the hopper 2 on the bracket 1 is more labor-saving, thereby reducing damage to the driving components.
[0060] More specifically, see Figure 4 A rack is provided on the running surface 11, with teeth of less than 1 mm in height. A limiting end 132 is provided on the first running wheel 13 adjacent to the friction surface 131, with the running surface 11 positioned between the limiting ends 132. The rack design increases the friction between the friction surface 131 of the first running wheel 13 and the running surface 11. However, since the teeth are less than 1 mm in height, this friction does not place an excessive burden on the drive components. The increased friction prevents the running wheel from spinning due to no load, thereby effectively preventing wear of the running wheel on the bracket 1.
[0061] In some embodiments, a side of the bracket 1 adjacent to the running surface 11 is provided with Figure 5The slide groove 12 shown is provided with a second running wheel 14 mounted on the feed box 23 of the hopper 2 via a shaft. The second running wheel 14 is positioned within the slide groove 12 and moves along the direction in which the slide groove 12 extends. The interaction between the first running wheel 13 and the second running wheel 14 ensures stable operation of the hopper 2 on the bracket 1, preventing excessive pressure on the first running wheel 13. The trajectory of the slide groove 12 guides the movement of the second running wheel 14 and aligns the opening of the feed box 23 with the feed inlet of the mixing system 7.
[0062] In some embodiments, reference Figure 1 The guide plate 6 includes a baffle and a rib. The baffle is fixed to the edge of the bell mouth 21 by welding or other means and is arranged along the feeding direction of the bell mouth 21. The rib is bent at both ends of the baffle, and has arc angles at the connection with the baffle, forming a triangular shape. The triangular rib enhances the stability of the baffle and forms an open guide with the baffle, which can smoothly guide the material into the bell mouth 21 without interfering with the operation of the construction personnel.
[0063] The above is only for explaining the implementation mode of the present invention and is not intended to limit the present invention. For those skilled in the art, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present invention without creative work should be included in the scope of protection of the present invention.
