Description

A feeding sensing device for a screening apparatus of an industrial screening machine. Technical Field

[0001] This utility model belongs to the field of screening machine technology, specifically relating to a feeding sensing device for a screening apparatus of an industrial and mining screening machine. Background Technology

[0002] Mining screening machines are downstream equipment of crushers in the mining industry, used to screen crushed materials and send them out according to different particle sizes. Mining screening machines generally feed materials into the screening device via a conveyor belt. During the feeding process, if the conveyor belt feeds too much material, it can easily lead to insufficient processing efficiency of the screening device, resulting in material blockage and jamming. If the conveyor belt feeds too little material, it will not fully utilize the performance of the screening device and waste its operating capacity. At the same time, the screening device also needs to adjust its vibration power according to the amount of material fed in. Therefore, it is essential to design a feeding sensing device for mining screening machines.

[0003] To address this issue, we have designed a feeding sensing device for a screening unit in an industrial screening machine, providing an alternative technical solution to the aforementioned technical problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a feeding sensing device for a screening apparatus of an industrial screening machine, so as to solve the problems mentioned in the background art regarding the use of existing screening devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding sensing device for a screening apparatus of an industrial screening machine, comprising a mounting plate, the mounting plate comprising a side plate and a bottom plate, a set of fixing rods disposed between the two sets of side plates, a buffer plate sleeved on the fixing rods, a sensing plate disposed on the lower side of the buffer plate, a vibration damper disposed between the sensing plate and the buffer plate, a sensing seat disposed at the connection position between the vibration damper and the sensing plate, and a pressure sensor disposed inside the sensing seat.

[0006] Preferably, the buffer plate is provided in multiple sets, and each set of the buffer plate is rotatably connected to the fixed rod through a set of rotating sleeves. The buffer plate is made of wear-resistant alloy material and is an arc-shaped plate.

[0007] Preferably, the upper lug of the shock absorber is connected to the back of the buffer plate, the lower lug of the shock absorber is connected to the sensing seat of the sensing plate, and a dust cover is provided on the outside of the connection position between the connecting rod of the shock absorber and the shock absorber cylinder.

[0008] Preferably, the mounting plate is fixedly connected to the feed hopper of the screening device by bolts, wherein the bottom plate is in contact with the back plate of the feed hopper, and the side plate is in contact with the side plate of the feed hopper.

[0009] Preferably, the buffer plate is inclined downwards, and the height of the buffer plate does not exceed the height of the feed hopper of the screening device.

[0010] Preferably, a counter is also provided inside the induction plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The frequency and magnitude of the downward pressure are sensed by the induction plate, and the amount of material fed in is then calculated by the controller, thereby realizing the feeding sensing of the screening device. A vibration damper is installed on the lower side of the buffer plate of the screening device. The impact force of the material can be buffered and absorbed by the vibration damper, thereby preventing the material from falling directly into the feed hopper. The combined sensing structure of the buffer plate and vibration damper can not only realize the sensing of the fed material, but also protect the feed hopper of the screening device to a certain extent, extending the service life of the screening device.

[0016] 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.

[0017] Referring to Figures 1-2, a feeding sensing device for a screening apparatus of an industrial screening machine includes a mounting plate 1. The mounting plate 1 includes a side plate and a bottom plate. A set of fixing rods 2 is arranged between the two sets of side plates. A buffer plate 3 is sleeved on the fixing rods 2. A sensing plate 5 is arranged on the lower side of the buffer plate 3. A vibration damper 11 is arranged between the sensing plate 5 and the buffer plate 3. A sensing seat 6 is arranged at the connection position between the vibration damper 11 and the sensing plate 5. A pressure sensor is arranged inside the sensing seat 6.

[0018] This solution proposes a feeding sensing device for a screening unit of an industrial screening machine. This device senses and calculates the amount of material fed into the machine via a conveyor belt, and then adjusts the operating power and feeding power of the screening unit based on the sensed material amount, achieving flexible adjustment. Specifically, the sensing device is installed in the feeding hopper 7 of the screening unit, directly below the feeding port of the feeding conveyor belt. The feeding conveyor belt transports the material (lumpy ore) to the feeding hopper 7. The material falls from the conveyor belt and touches the buffer plate 3, thus pressing down on the buffer plate 3. The downward pressure of the buffer plate 3 is sensed by the sensing seat 6 of the sensing plate 5, thereby sensing the feeding of material. The frequency and magnitude of the downward pressure are sensed by the sensing plate 5, and then the controller calculates the amount of material fed in, thus realizing the feeding sensing of the screening unit.

[0019] In this design, a vibration damper 11 is installed on the lower side of the buffer plate 3. The impact force of the material can be buffered and absorbed by the vibration damper 11, thereby preventing the material from falling directly into the feed hopper 7. The combined sensing structure of the buffer plate 3 and the vibration damper 11 can not only sense the fed material, but also protect the feed hopper 7 of the screening device to a certain extent, extending the service life of the screening device. It should be noted that this technical solution is used to sense the amount of fed material. The size and weight of the material will vary depending on the type of ore. The sensing is a rough estimate, which is used to adjust the feeding speed of the conveyor belt and the screening power of the screening device, thereby avoiding clogging of the screening device or waste of the screening device's operating power.

[0020] Furthermore, multiple sets of buffer plates 3 are provided, and each set of buffer plates 3 is rotatably connected to the fixed rod 2 through a set of rotating sleeves 4. The buffer plates 3 are made of wear-resistant alloy material and are arc-shaped plates.

[0021] With this technical solution, when the material falls into the screening device, the material impacts the buffer plate 3. The buffer plate 3 rotates around the fixed rod 2 and is compressed into the vibration damper 11. The buffer plate 3 is made of wear-resistant alloy material, which can improve its strength, prevent the buffer plate 3 from impact and wear, and improve its service life. The buffer plate 3 is an arc-shaped plate that can directly guide the material downward and convey it into the interior of the screening device.

[0022] Furthermore, the upper lug 9 of the shock absorber 11 is connected to the back of the buffer plate 3, the lower lug 10 of the shock absorber 11 is connected to the sensing seat 6 of the sensing plate 5, and a dust cover 8 is provided on the outside of the connection position between the connecting rod of the shock absorber 11 and the cylinder of the shock absorber 11.

[0023] In this scheme, a set of shock absorbers 11 is provided on the back of each set of buffer plates 3. The shock absorber 11 absorbs energy through spring buffering, avoiding direct rigid collision with the sensing plate 5. The shock absorber 11 is equipped with a dustproof structure to prevent dust from the material from entering the shock absorber 11 and affecting its shock absorption performance.

[0024] Furthermore, the mounting plate 1 is fixedly connected to the reducing hopper of the screening device by bolts, wherein the bottom plate is attached to the back plate of the feeding hopper 7, and the side plate is attached to the side plate of the feeding hopper 7.

[0025] Mounting plate 1 is fixed by a base plate and side plates. The side plates and base plates are fixed in different directions, which can effectively improve the fixing stability and reduce the loosening and falling off of bolts. The bolt fixing method makes it easy to disassemble and install mounting plate 1, and it is convenient to use. In other embodiments, mounting plate 1 can also be directly fixed to the feed hopper 7 of the screening device by welding to ensure the installation stability of the sensing device.

[0026] Furthermore, the buffer plate 3 is inclined downwards, and the height of the buffer plate 3 does not exceed the height of the feed hopper 7 of the screening device.

[0027] The buffer plate 3 is inclined downward, and the height of the buffer plate 3 does not exceed the height of the feed hopper 7 of the screening device, which can prevent the material from rebounding and flying out. In conjunction with the arc-shaped buffer plate 3, the material can be guided downward into the internal space of the screening device.

[0028] Furthermore, a counter is also installed inside the sensor plate 5.

[0029] The induction plate 5 is electrically connected to the central control system of the screening machine. The counter of the induction plate 5 is used to sense the frequency of the material, and the pressure sensor is used to sense the size of the material. In this way, the amount of material fed in can be calculated, and the screening machine can be adjusted.

[0030] Working Principle: The sensing device is installed in the feed hopper 7 of the screening device, directly below the feed inlet of the feed conveyor belt. The feed conveyor belt transports the material (lumpy ore) to the feed hopper 7. The material falls from the conveyor belt and touches the buffer plate 3, thus pressing down on the buffer plate 3. The downward pressure of the buffer plate 3 is sensed by the sensing seat 6 of the sensing plate 5, thereby sensing the feeding of material. The frequency and magnitude of the downward pressure are sensed by the sensing plate 5, and then the controller calculates the amount of material fed in, thus realizing the feeding sensing of the screening device. A vibration damper 11 is installed on the lower side of the buffer plate 3 of the screening device. The impact force of the material can be buffered and absorbed by the vibration damper 11, thereby preventing the material from falling directly into the feed hopper 7. The combined sensing structure of the buffer plate 3 and the vibration damper 11 not only realizes the sensing of the fed material, but also provides a certain degree of protection for the feed hopper 7 of the screening device, extending the service life of the screening device.
