Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining crushers, specifically to a mining crusher with a screening function. Background Technology
[0002] In traditional mining processes, ore typically undergoes multiple steps to reach the required size and purity. First, large pieces of ore are crushed into smaller particles using a crusher; then these particles are screened to ensure they meet specific size standards. This process may involve multiple stages of crushing and screening to progressively reduce ore size and remove impurities.
[0003] However, traditional mining crushers often only provide a single crushing function, which means that the crushed material must be classified into particles through additional screening equipment. This operation mode not only increases the investment cost and operating expenses of the equipment, but also reduces the overall production efficiency. Therefore, we propose a mining crusher with screening function to optimize this process, reduce intermediate links, and thus improve economic benefits and production efficiency. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this utility model provides a mining crusher with screening function.
[0005] The technical solution is as follows: A mining crusher with screening function includes a base and a crushing frame. The base is the load-bearing carrier of the crusher. The crushing frame is fixedly installed on one side of the base by a bracket. The crushing frame is a bucket-shaped frame that is wider at the top and narrower at the bottom. It also includes crushing rollers, baffles, screen plates, guide rods, and vibrating components. Two crushing rollers are symmetrically and rotatably installed inside the crushing frame. The crushing rollers crush the ore poured into the crushing frame by electric drive. Arc-shaped baffles are symmetrically fixed at the bucket-shaped structure on the inner wall of the crushing frame. The baffles are distributed on one side of the two crushing rollers and are used to block the debris splashed by the crushing rollers when crushing the ore. Guide rods are fixedly connected upward at the four corners of the top of the base. The screen plate is slidably installed on the base through the top guide rods. The screen plate is a plate that is inclined to one side and is located below the outlet of the crushing frame. A spring is provided between the screen plate and each guide rod. A vibrating component for vibrating the screen plate is provided on one side of the base.
[0006] Furthermore, support pads are fixedly installed at the four corners of the bottom surface of the base. The support pads are made of rubber and are used to buffer the base, reduce the transmission of vibration generated by the crusher to the ground when crushing ore, and improve the safety of the crusher.
[0007] Furthermore, the vibrating component includes a motor and a cam. The motor is fixedly installed on one side of the top of the base, and the cam is fixedly installed on the output shaft of the motor. The cam and the screen plate are in contact with each other. The motor drives the cam to intermittently squeeze the screen plate, thereby vibrating the screen plate and improving the efficiency of screening ore.
[0008] Furthermore, a collection frame 1 is provided directly below the sieve plate on the base. The collection frame 1 is used to collect the broken minerals that pass through the sieve plate screen. A collection frame 2 is provided on one side of the sieve plate on the base, with the lowest point of the sieve plate facing the collection frame 2. The collection frame 2 is used to collect the broken minerals that do not pass through the sieve plate screen and slide down. Both the collection frame 1 and the collection frame 2 are slidably and detachably installed on the base. The collection frame 1 and the collection frame 2 can be easily replaced after they are full of minerals.
[0009] Furthermore, a mounting bracket is fixedly installed on the base near the crushing frame, and a fan is mounted on the top of the mounting bracket. The fan is located at the top opening of the crushing frame and is used to remove the dust generated during crushing on the crushing frame, thereby reducing the pollution of the crusher's working environment by dust.
[0010] Furthermore, it also includes a dust exhaust pipe, which is mounted on the mounting frame and connected to the auxiliary fan. The dust exhaust pipe is used to discharge the dust extracted by the fan to a safe disposal location, thereby improving the environmental friendliness of the crusher.
[0011] The beneficial effects are: 1. This utility model integrates the crushing frame and screen plate into one device, reducing the mineral transfer links and improving the overall efficiency of ore processing. By directly screening after crushing, it achieves rapid and effective ore particle size classification.
[0012] 2. The screen plate of this utility model is connected to the spring through the guide rod and is driven by the vibrating component to generate vibration, so that the ore can be screened while rolling on the screen plate, which significantly reduces the risk of screen blockage and improves screening efficiency.
[0013] 3. This utility model can also effectively remove dust generated during the crushing process by setting a fan on the top of the crushing frame and using a dust exhaust pipe, thereby reducing pollution to the working environment and improving environmental performance.

Detailed Implementation
[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings. To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside appearing or about to appear in this document are based solely on the accompanying drawings and are not intended to specifically limit the present invention.
[0020] A mining crusher with screening function, such as Figures 1-4 As shown, the crusher includes a base 1 and a crushing frame 2. The base 1 serves as the load-bearing carrier of the crusher. The crushing frame 2 is fixedly installed on one side of the base 1 via a bracket 21. The crushing frame 2 is a bucket-shaped frame that is wider at the top and narrower at the bottom. The crusher also includes crushing rollers 3, baffles 4, a screen plate 5, guide rods 6, and vibrating components. Two crushing rollers 3 are symmetrically and rotatably installed inside the crushing frame 2. The crushing rollers 3 are electrically driven to crush the ore poured into the crushing frame 2. Circular arc baffles 4 are symmetrically fixed at the bucket-shaped structure on the inner wall of the crushing frame 2. The baffles 4 are distributed on one side of the two crushing rollers 3 and are used to block the debris splashed during the crushing of the ore by the crushing rollers 3. The base 1 has four corners at its top. Guide rods 6 are fixed upwards on each of the base 1. A screen plate 5 is slidably installed on the base 1 through the top guide rods 6. The screen plate 5 is a plate that tilts to one side and is located below the outlet of the crushing frame 2. A spring 7 is provided between the screen plate 5 and each guide rod 6. A vibrating element for vibrating the screen plate 5 is provided on one side of the base 1. After the ore is crushed by the crushing roller 3 in the crushing frame 2, it will fall from the bottom outlet of the crushing frame 2 onto the screen plate 5. At this time, the vibrating element, together with the spring 7 on the guide rod 6, repeatedly vibrates the screen plate 5, so that the ore rolls down the screen plate 5 at an incline while vibrating and screening, thereby improving the screening efficiency of the screen plate 5 and reducing the clogging of the screen plate 5.
[0021] like Figure 1 and Figure 3 As shown, support pads 101 are fixedly installed at the four corners of the bottom surface of the base 1. The support pads 101 are made of rubber and are used to buffer the base 1, reduce the vibration generated by the crusher when crushing ore and transmit it to the ground, and improve the safety of the crusher.
[0022] like Figure 3 As shown, the vibrating component includes a motor 8 and a cam 9. The motor 8 is fixedly installed on one side of the top of the base 1, and the cam 9 is fixedly installed on the output shaft of the motor 8. The cam 9 and the screen plate 5 are in contact with each other. The motor 8 drives the cam 9 to intermittently squeeze the screen plate 5, thereby vibrating the screen plate 5 and improving the efficiency of screening ore.
[0023] like Figure 1 and Figure 3 As shown, a collection frame 10 is provided on the base 1 directly below the sieve plate 5. The collection frame 10 is used to collect the broken minerals that pass through the sieve plate 5. A collection frame 21 is provided on one side of the sieve plate 5 on the base 1, with the lowest point of the sieve plate 5 facing the collection frame 21. The collection frame 21 is used to collect the broken minerals that do not pass through the sieve plate 5 and fall down. Both the collection frame 10 and the collection frame 21 are slidably and detachably installed on the base 1. The collection frame 10 and the collection frame 21 can be easily replaced after they are full of minerals.
[0024] like Figure 1 and Figure 4 As shown, a mounting bracket 12 is fixedly installed on the base 1 near the crushing frame 2. A fan 13 is mounted on the top of the mounting bracket 12. The fan 13 is located at the top opening of the crushing frame 2. The fan 13 is used to remove the dust generated by crushing on the crushing frame 2 and reduce the pollution of the crusher's working environment by the dust.
[0025] like Figure 1 and Figure 4 As shown, it also includes a dust discharge pipe 14. The dust discharge pipe 14 is mounted on the mounting frame 12. The dust discharge pipe 14 is connected to the support fan 13. The dust discharge pipe 14 is used to discharge the dust extracted by the fan 13 to a safe disposal location, thereby improving the environmental friendliness of the crusher.
[0026] When using this crusher to crush ore, the ore is fed in through the top opening of the crushing frame 2. Two electrically driven crushing rollers 3 rotate at high speed in opposite directions, crushing the ore to the target particle size. During the crushing process, the arc-shaped baffles 4 on both sides effectively block splashing debris, ensuring a safe working environment. The crushed ore falls from the bottom outlet of the crushing frame 2 onto the inclined screen plate 5. At this time, the motor 8 on one side of the base 1 drives the cam 9 to periodically push the screen plate 5, creating reciprocating vibration in conjunction with the spring 7 on the guide rod 6. The vibration of the screen plate 5 causes the ore particles to tumble and slide down the inclined surface, with fine mineral particles passing through the screen and falling directly below. The detachable collection frame 10 allows coarse particles to slide to the lowest end due to vibration inertia and enter the side collection frame 11, thus achieving efficient classification simultaneously during crushing. At the same time, the fan 13 on the top of the mounting frame 12 runs continuously, sucking in the dust raised during crushing and conveying it to the dust removal equipment or safe area through the dust discharge pipe 14, greatly reducing dust pollution. In conjunction with the rubber support pad 101 at the bottom of the base 1, the vibration energy of the crusher during operation is absorbed, reducing vibration transmitted from the ground. When the collection frames 10 and 11 are full, they can be quickly slid off and replaced to ensure continuous operation.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
