Description

Technical Field

[0001] This utility model relates to the field of separator technology, and in particular to a sand and gravel separator. Background Technology

[0002] To prevent the waste of water resources and the pollution of the environment caused by the wastewater slurry generated by concrete production enterprises during the cleaning of concrete mixer trucks, and to achieve the separation and recycling of concrete sand and gravel, people have developed and manufactured a variety of concrete sand and gravel separators. The concrete sand and gravel separator, also known as concrete sand and gravel separation slurry recycling equipment, is the core equipment of the concrete recycling structure. It is mainly used to clean, separate and recycle the wastewater from cleaning the mixer trucks and the sand and gravel in the residual concrete.

[0003] A search revealed Chinese Patent Publication No. CN219880485U, which discloses a sand and gravel separator, relating to the field of sand and gravel separator technology. The separator includes a housing, a screen plate inclined downwards within the housing, several through slots for sand to pass through, a feed inlet at the top of the housing, and a discharge outlet on the side wall of the housing. One inclined end of the screen plate extends into the discharge outlet. A vibrating motor is mounted on the outer wall of the housing, and several elastic impact blocks are mounted on the top wall of the screen plate. This application uses impact blocks to cause the stones to collide with them, shaking off the sand adhering to the stones. The impact blocks are elastic, reducing the chance of crushing the stones, thus facilitating the separation of sand and stone and improving the sand recovery rate. However, the above structure does not consider that during the feeding process, particles in the concrete material may form arch-shaped accumulations due to mutual compression and adhesion, preventing the material from falling normally and affecting the normal operation and separation efficiency of the equipment, making it difficult to meet usage requirements. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sand and gravel separator, which aims to improve the problem that material compression and accumulation in the prior art easily leads to bridging, thereby reducing the working efficiency and stability of the equipment.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a sand and gravel separator, including a feed inlet, a guide pipe fixedly connected to the bottom right side of the feed inlet, a stone separating mechanism fixedly connected to the right end of the guide pipe, multiple sliding sleeves rotatably connected to the top left side of the stone separating mechanism, a sliding rod slidably connected to the left side of the sliding sleeves, a spring provided on the outer wall of the sliding rod, a connecting plate fixedly connected to the middle left side of the stone separating mechanism, a servo motor fixedly connected to the top right side of the connecting plate, a transmission bar fixedly connected to the output end of the servo motor, a vibrating bar rotatably connected to the bottom rear side of the transmission bar, the top of the vibrating bar rotatably connected to the bottom end of the feed inlet, and a filter screen mechanism provided at the top of the feed inlet, the filter screen mechanism being used to disperse the incoming material to prevent accumulation.

[0006] The above technical solution involves the following: the feed inlet is located at the front of the entire device, responsible for receiving materials. A guide pipe is fixedly connected to the bottom right side of the feed inlet, ensuring smooth material flow from the feed inlet into the guide pipe. Similarly, a stone-separating mechanism is fixedly connected to the right end of the guide pipe. This mechanism separates stones and impurities from the material. Multiple sliding sleeves are rotatably connected to the top left side of the stone-separating mechanism. These sleeves move with the vibration of the feed inlet, working in conjunction with sliding rods and springs to maintain the stability and flexibility of the sliding rods within the sleeves, thus reducing vibration. A connecting plate is fixedly connected to the middle left side of the stone-separating mechanism. The connecting plate serves as the connecting component between the stone separating mechanism and the subsequent devices. A servo motor is fixedly connected to the top right side of the connecting plate. As a power source, the servo motor can precisely control the movement of the subsequent devices. A transmission bar is fixedly connected to the output end of the servo motor. The transmission bar converts the rotational motion of the servo motor into linear motion and transmits it to the vibrating bar. The top of the vibrating bar is rotatably connected to the bottom end of the feed inlet. The vibration function of the vibrating bar helps to evenly distribute and flow the material. A filter screen mechanism is set at the top of the feed inlet. The main function of the filter screen mechanism is to disperse the incoming material and prevent the material from accumulating at the feed inlet, ensuring the smooth operation of the entire device.

[0007] As a further description of the above technical solution:

[0008] The filter mechanism includes a mounting rod, the left and right sides of which are rotatably connected to the rear top of the feed inlet. A coarse-mouthed filter is fixedly connected to the front side of the mounting rod. A rotating rod is rotatably connected to the inner wall of the mounting rod. Multiple locking holes are provided on the left and right sides of the top of the rotating rod. A threaded head is threaded to the inner wall of the locking hole, and a pull rod is fixedly connected to the top of the threaded head.

[0009] Through the above technical solution: the mounting rod is the foundation of the entire mechanism, ensuring the stable installation of the filter screen mechanism. A coarse-mouthed filter screen is also fixedly connected to the front of the mounting rod, responsible for dispersing the materials entering the equipment, ensuring the smoothness of the subsequent processing and the long-term stable operation of the equipment. A rotating rod is rotatably connected to the inner wall of the mounting rod. The rotating rod allows the user to adjust its position according to actual needs to adapt to different working environments and requirements. Multiple locking holes are opened on both sides of the top of the rotating rod. These locking holes are used to lock the filter screen mechanism for precise installation. By threading the threaded head to the inner wall of the locking hole, the user can easily fix the rotating rod in the required position, ensuring the stability and reliability of the filter screen mechanism during operation. In order to achieve precise control of the rotating rod, a pull rod is fixedly connected to the top of the threaded head. The pull rod allows the user to adjust the position of the rotating rod by a simple pulling action, thereby realizing the opening and closing of the coarse-mouthed filter screen. This not only improves the ease of operation of the filter screen mechanism, but also ensures that the filter screen mechanism can maintain the best working condition under various complex working conditions.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the servo motor is provided with a protective shell, and the outer wall of the protective shell is provided with multiple heat dissipation vents.

[0012] Through the above technical solution, this protective shell provides additional physical protection for the servo motor, preventing damage from external factors. Multiple heat dissipation vents effectively promote air circulation, extend its service life, and improve work efficiency.

[0013] As a further description of the above technical solution:

[0014] The top front of the stone-splitting mechanism is rotatably connected to a closed door, and an observation window is fixedly connected to the front of the closed door.

[0015] Through the above technical solution: the closed door can protect the internal components of the stone-splitting mechanism from external contamination, and can be easily opened when needed for maintenance and inspection, while the observation window allows for a direct view of the working status of the stone-splitting mechanism.

[0016] As a further description of the above technical solution:

[0017] The bottom left and right sides of the stone separating mechanism are fixedly connected to a fixing plate, and the front and back sides of the fixing plate are provided with multiple fixing holes.

[0018] Through the above technical solution: the fixing plate provides additional support for the stone-splitting mechanism, ensuring its stability under various working conditions, and the fixing holes can be used to firmly install the stone-splitting mechanism in the appropriate position, ensuring its accuracy and reliability during operation.

[0019] As a further description of the above technical solution:

[0020] A reinforcing frame is fixedly connected to the bottom of the connecting plate, and a stone-splitting opening is provided at the bottom right side of the front end of the stone-splitting mechanism.

[0021] The above technical solution involves reinforcing the frame to enhance the stability of the entire device, and the function of the stone separator to initially separate stones and sand from the material.

[0022] As a further description of the above technical solution:

[0023] A support block is fixedly connected to the rear right bottom of the stone separating mechanism, and a discharge pipe is fixedly connected to the top of the support block.

[0024] Through the above technical solution: the presence of the support block not only provides additional support for the entire device, but also ensures the stability of the device, and the discharge pipe is responsible for conveying the separated sand and gravel.

[0025] As a further description of the above technical solution:

[0026] The right end of the discharge pipe is fixedly connected to a discharge port, and a sand separating mechanism is provided on the right side of the discharge port.

[0027] The above technical solution is as follows: the discharge port is for convenient material output, and the sand separating mechanism is to further separate the sand in the material to achieve a finer separation effect.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the material is introduced into the stone separating mechanism through the guide pipe. The sliding sleeve and the sliding rod are connected by sliding and the vibration is buffered by the spring. After the servo motor is started, the transmission bar drives the vibrating bar to move, causing the feed port to vibrate and smoothly convey the material. This structure vibrates the feed part, buffers the vibration, improves stability and feeding effect, and meets the usage requirements.

[0030] 2. In this utility model, the coarse-mouthed filter screen can be placed on top of the feed inlet by the configuration of the mounting rod, preventing the material from accumulating directly. The filter screen is rotatably connected to the rotating rod through the inner wall. The rotating rod is provided with a locking hole and is threadedly fixed to the threaded head at the bottom of the pull rod, so as to achieve a stable installation of the structure. Pulling the pull rod can open the filter screen. This design effectively avoids clogging, and the switch is flexible, easy to disassemble and maintain, improves convenience and feeding efficiency, and meets the needs of use.

Pulling the pull rod 206 opens the coarse filter screen 202. This structure initially prevents accumulation and clogging, allows for flexible opening and closing, and is easy to install, replace, and maintain, improving convenience and feeding efficiency, and meeting usage requirements.
