Description

Technical Field

[0001] This utility model relates to the field of screening machine technology, specifically to a material spreading structure for a banana screen used in mining. Background Technology

[0002] Banana screens, named for their banana-like shape, are often used for mineral screening. Traditional banana screens have a wide screen surface, which limits the width of the funnel at the head of the material conveyor belt. When materials are fed through the screen's feed hopper, they tend to pile up on the screen, making it difficult to achieve uniform material distribution across the entire screen surface. This often results in incomplete screening, requiring repeated screening. Utility Model Content

[0003] The purpose of this utility model is to provide a material spreading structure for a banana screen used in mining, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a screen base, a drive motor mounted on the screen base, and a vibrating rod rotatably connected to the screen base, wherein the screen base is provided with adjustment grooves on both the front and back sides;

[0005] The adjusting groove is internally connected to a connecting block, and each of the two connecting blocks is fitted with a baffle plate that works with the adjusting groove on its opposite side. A rotating rod is rotatably connected between the two connecting blocks, and a material spreading auger is symmetrically fitted on the surface of the rotating rod. A transmission mechanism is provided between the excitation rod and the rotating rod.

[0006] In a further embodiment, the transmission mechanism includes two rotating wheels and a transmission belt that is pulsatingly connected to the two rotating wheels. The two rotating wheels are respectively fixed to one end of the excitation rod and one end of the rotating rod.

[0007] In a further embodiment, the top of the screen base is symmetrically equipped with adjusting hydraulic cylinders, the output end of which extends into the interior of the adjusting groove and is fixedly connected to the connecting block.

[0008] In a further embodiment, a tensioner is mounted on the front of the screen base, and the tensioning wheel of the tensioner is used in conjunction with a transmission belt.

[0009] In a further embodiment, a buffer plate is installed inside the sieve base, a sieving unit is installed inside the sieve base, and an excitation block is fixedly installed on the surface of the excitation rod.

[0010] In a further embodiment, a support block is fixedly connected to both the front and back of the screen base, and a support seat is provided on both the front and back of the screen base. A support spring is assembled between the support seat and the support block.

[0011] In a further embodiment, the bottom of the screen base is provided with a material inlet, and the bottom of the screen base is fixedly connected with a guide seat that cooperates with the material inlet.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a rotating rod installed between two connecting blocks. Two flattening augers with opposite orientations are mounted on the rotating rod. When the rotating rod drives the augers to rotate, the accumulated material falling from the screen hopper onto the buffer plate can be conveyed from the center to both sides, achieving the purpose of spreading the material, avoiding uneven material distribution, reducing material return, and improving the working efficiency of the screen.

[0014] This invention, through the design of the transmission mechanism, enables the vibrating rod of the screening machine to be driven by the drive motor to rotate, and the rotation of the vibrating rod drives the rotating rod to rotate, so that the leveling auger on the rotating rod can be driven to perform leveling work without the need for an additional drive source, thus ensuring the energy-saving effect of the screening machine during operation.

[0015] This invention, through the design of an adjustable hydraulic cylinder, allows for the adjustment of the height between the rotating rod and the buffer plate between the two connecting blocks, thereby adjusting the height of the auger. Combined with the tensioner's action on the transmission mechanism, this ensures the normal rotation of the auger on the rotating rod, achieving the purpose of adjusting and flattening the thickness, thus improving practicality.

[0021] 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.

[0022] This embodiment discloses a material spreading structure for a mining banana screen, including a screen base 1, a drive motor 2 mounted on the screen base 1, and a vibrating rod 3 rotatably connected to the screen base 1. Adjustment grooves 4 are provided on both the front and back of the screen base 1. Figure 1 and Figure 4 As shown in this application, the screen base 1 is used for the installation and fixing of the material spreading structure. The drive motor 2 is mounted on the back of the screen base 1. The drive motor 2 serves as a rotation source to provide rotational power for the excitation rod 3 of the screen machine. The excitation rod 3 is located at the top of the screen base 1 and is rotatably connected to the screen base 1. The end of the excitation rod 3 near the drive motor 2 is detachably connected to the drive motor 2. In this application, it is preferably connected by a coupling. There are two adjusting grooves 4, which are designed on the two side walls of the screen base 1 respectively, for installing and fixing the material spreading mechanism.

[0023] Furthermore, a buffer plate 12 is installed inside the screen base 1, a screening unit 19 is installed inside the screen base 1, a vibrating block 13 is fixedly installed on the surface of the vibrating rod 3, support blocks 14 are fixedly connected to both the front and back of the screen base 1, support seats 15 are provided on both the front and back of the screen base 1, a support spring 16 is installed between the support seat 15 and the support block 14, a material outlet 17 is opened at the bottom of the screen base 1, and a guide seat 18 that cooperates with the material outlet 17 is fixedly connected to the bottom of the screen base 1. Figure 1 and Figure 4As shown, the buffer plate 12 is designed inside the screen base 1 to buffer the material falling from the screen hopper. The buffer plate 12 has a certain slope, which allows the material to be smoothly guided into the screening unit 19 when the screen vibrates. The buffer plate 12 can prevent the material from directly impacting the screen base 1, protecting the screen base 1 and ensuring its service life. The screening unit 19 is used for screening materials. In this application, the screening unit 19 is preferably a screening screen, used to screen the material introduced from the buffer plate 12. The number of support blocks 14 and support seats 15 is the same, used to support the screen base 1. The support blocks 14 and support seats 15 are installed between each other. A support spring 16 is provided to provide elastic support for the screen base 1, facilitating the vibration of the screen base 1. The material inlet 17 is designed at the bottom of the screen base 1 for feeding the material screened by the screening unit 19. The guide seat 18 is designed at the material inlet 17 for guiding the material. The exciter block 13 is mounted on the exciter rod 3. When the drive motor 2 drives the exciter rod 3 to rotate, the exciter rod 3 can drive the exciter block 13 to rotate. Because the exciter block 13 is eccentrically designed, the rotation of the exciter block 13 will generate excitation force, which is transmitted to the screen base 1 through the exciter rod 3, thereby driving the screening machine to perform excitation work.

[0024] The adjusting groove 4 is internally connected by connecting blocks 5. Each of the two connecting blocks 5 has a baffle 6 on its opposite side that cooperates with the adjusting groove 4. A rotating rod 7 rotates between the two connecting blocks 5. A material spreading auger 8 is symmetrically mounted on the surface of the rotating rod 7. A transmission mechanism 9 is provided between the vibrating rod 3 and the rotating rod 7. Figure 1 , Figure 2 and Figure 3As shown, two connecting blocks 5 are respectively located inside two adjusting grooves 4. The connecting blocks 5 and adjusting grooves 4 are slidably connected, allowing the connecting blocks 5 to slide and adjust their position within the adjusting grooves 4. A baffle 6 is designed on the opposite side of the two connecting blocks 5 and is located inside the screen base 1. The baffle 6 is used to seal the adjusting grooves 4, preventing material from entering the adjustment gap between the connecting blocks 5 and the adjusting grooves 4 when the connecting blocks 5 are adjusted within them. A rotating rod 7 is designed between the two connecting blocks 5 and is rotatably connected to them. The rotating rod 7 is used to install and fix the auger. The auger on the rotating rod 7 is divided into two parts, and the two parts... The auger is designed in the opposite direction. It is fixed on the rotating rod 7. When the auger rotates, due to its special curved shape, it can transport the material piled up in the middle to both sides, thus flattening the material and avoiding the situation where the material piles up and the screening effect deteriorates. The transmission mechanism 9 is designed between the vibrating rod 3 and the rotating rod 7 for transmission between them. When the vibrating rod 3 is driven by the drive motor 2, the rotation of the vibrating rod 3 can drive the rotating rod 7 to rotate under the action of the transmission mechanism 9. After the rotating rod 7 rotates, it can drive the auger to rotate, thus performing the material spreading work. This avoids the situation where the material piles up on the screen and it is difficult to achieve uniform material distribution on the entire screen surface, which can lead to incomplete screening and the need for repeated screening.

[0025] Furthermore, the transmission mechanism 9 includes two rotating wheels 91 and a transmission belt 92 that is connected to the two rotating wheels 91. The two rotating wheels 91 are respectively fixed to one end of the excitation rod 3 and one end of the rotating rod 7, as shown below. Figure 1 and Figure 3 As shown, two rotating wheels 91 are fixedly connected to the rotating rod 7 and the excitation rod 3 respectively. When the excitation rod 3 is driven to rotate by the drive motor 2, it can drive the rotating wheel 91 on the excitation rod 3 to rotate. The transmission belt 92 is installed between the rotating wheel 91 on the rotating rod 7 and the rotating wheel 91 on the excitation rod 3. When the rotating wheel 91 on the excitation rod 3 rotates, it can drive the rotating wheel 91 on the rotating rod 7 to rotate under the action of the transmission belt 92, thereby driving the rotating rod 7 to rotate. This achieves the purpose of driving the material spreading structure to work without the need for additional drive equipment, thus achieving the purpose of energy saving.

[0026] Finally, symmetrically mounted adjusting hydraulic cylinders 10 are fitted on the top of the screen base 1. The output end of the adjusting hydraulic cylinder 10 extends into the interior of the adjusting groove 4 and is fixedly connected to the connecting block 5. A tensioner 11 is mounted on the front of the screen base 1. The tensioning wheel of the tensioner 11 works in conjunction with the transmission belt 92, such as... Figure 1As shown, there are two adjusting hydraulic cylinders 10, both of which are installed on the top of the screen base 1. The output end of the adjusting hydraulic cylinder 10 passes through the interior of the adjusting groove 4 and is fixedly connected to the connecting block 5. When the two adjusting hydraulic cylinders 10 work at the same time, they can drive the two connecting blocks 5 to move in the position inside the adjusting groove 4, thereby adjusting the height of the rotating rod 7. This allows the auger on the rotating rod 7 and the buffer plate 12 to be adjusted, achieving the purpose of adjusting the thickness of the spreading operation. The tensioner 11 is installed on the front of the screen base 1 and is used to adjust the tension of the transmission belt 92 in the transmission mechanism 9. It can keep the transmission belt 92 in a taut state at all times, avoiding slippage when transmitting the material spreading structure.
