Description

Technical Field

[0001] This utility model belongs to the technical field of industrial and mining screening machines, specifically relating to a multi-stage conveying device for a screening machine. Background Technology

[0002] Mining screening machines are downstream equipment of crushers. Their main function is to screen the crushed ore into materials of different particle sizes. In the current market, most screening machines are fixed structures. However, in order to cope with the complex environment of different ore mining and the frequently changing operating scenarios, there are also some mobile mining screening machines on the market.

[0003] Mobile industrial screening machines typically use a single moving mechanism (mostly a tracked moving mechanism) to drive the entire machine. The conveying device is used on the screening machine to deliver the screened material. Due to the nature of the screening machine's work, multiple conveying mechanisms are required. The materials that the screening machine comes into contact with daily are mostly ores, and the daily throughput is huge. At the same time, the stability of the machine's movement and operation must be considered, which makes the design of the conveying device of the screening machine quite challenging.

[0004] To address this issue, we designed a multi-stage conveying device for a screening machine, providing an alternative technical solution. Utility Model Content

The small material conveyor belt is located at the bottom layer of the screening machine and on one side of the screening machine. The medium material conveyor belt and the large material conveyor belt are respectively located at the middle layer and the top layer of the screening machine, and both the medium material conveyor belt and the large material conveyor belt are located on the opposite side from the small material conveyor belt. The medium material conveyor belt and the large material conveyor belt are angularly offset to form a spatial difference, and the large material conveyor belt extends in the opposite direction of the screening device.

[0007] Preferably, the screening device has three layers.

[0011] Preferably, the multi-stage conveying device is equipped with a main unit and a hydraulic station on its front side.

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

[0017] 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.

[0018] Reference Figure 1-2A multi-stage conveying device for a screening machine includes a large material conveyor belt 1, a medium material conveyor belt 2, and a small material conveyor belt 3. The small material conveyor belt 3 is located at the bottom layer of the screening machine and on one side of the screening machine. The medium material conveyor belt 2 and the large material conveyor belt 1 are respectively located at the middle layer and the top layer of the screening machine. The medium material conveyor belt 2 and the large material conveyor belt 1 are both located on the opposite side of the small material conveyor belt 3. The medium material conveyor belt 2 and the large material conveyor belt 1 are angularly offset to form a spatial difference. At the same time, the large material conveyor belt 1 extends in the opposite direction of the screening device 4.

[0019] This solution proposes a multi-stage conveying device, which includes a large material conveyor belt 1, a medium material conveyor belt 2, and a small material conveyor belt 3, used to output the screened large-diameter material, medium-diameter material, and small-diameter material, respectively. During operation, the small, medium, and large materials decrease in sequence. The small material conveyor belt 3 is set separately on one side of the screening machine, while the large material conveyor belt 1 and the medium material conveyor belt 2 are set on the other side of the screening machine. This can effectively balance the weight of the materials, so that the center of gravity of the equipment falls in the middle of the screening machine during operation, making the center of gravity of the screening machine stable. At the same time, the small material conveyor belt 3 is set separately and placed at the bottom layer. On the one hand, it is compatible with the screening device 4, which can effectively connect with the material of the screening device 4. On the other hand, it helps to lower the center of gravity (the heaviest small material is sent out from the bottom layer), making the equipment more stable.

[0020] The large material conveyor belt 1 and the medium material conveyor belt 2 are set on one side. The two are installed at different angles and on different layers, which facilitates the layout and installation of the conveyor belts. At the same time, the large material conveyor belt extends to the side and is aligned with the screening device 4. The center of gravity of a large number of conveyor belts can be balanced by the screening device 4, thereby making the mobile screening machine highly stable during operation.

[0021] Furthermore, the screening device 4 is provided with three layers. The screening device 4 is connected to the large material conveyor belt 1 through the upper material guide port 5, the screening device 4 is connected to the medium material conveyor belt 2 through the middle material guide port 6, and the screening device 4 is connected to the small material conveyor belt 3 through the lower material guide port 7.

[0022] Through this technical solution, the three-layer structure of the screening device 4 screens the material into large, medium and small materials, and sends it out from the upper, middle and lower layers. The three sets of conveyor belts of the conveying device are arranged around the screening device 4, so as to send out the material screened by the screening device 4 in grades.

[0023] Furthermore, a transverse conveyor belt 8 is provided between the large material conveyor belt 1 and the upper guide port 5, and a baffle plate is provided at the bottom end of the large material conveyor belt 1.

[0024] Large materials screened out by the screening device enter the transverse conveyor belt 8 through the upper guide port 5. The transverse conveyor belt 8 drives the material to move horizontally, thereby sending the material to the large material conveyor belt 1. The baffle plate at the bottom of the large material conveyor belt 1 is used to receive the material and prevent the material from falling.

[0025] Furthermore, the bottom of the intermediate material conveyor belt 2 is located at the lower end of the intermediate material guide port 6, and the bottom of the small material conveyor belt 3 is located at the lower end of the lower material guide port 7, with the intermediate material conveyor belt 2 and the small material conveyor belt 3 arranged in opposite directions.

[0026] Both the intermediate material conveyor belt 2 and the minor material conveyor belt 3 are arranged horizontally, and their bottom ends are directly connected to the screening device 4. The intermediate material conveyor belt 2 and the minor material conveyor belt 3 are in opposite directions, thereby balancing the center of gravity on both sides of the screening machine.

[0027] Furthermore, hydraulic adjustment devices 9 are installed at the lower ends of the large material conveyor belt 1, the medium material conveyor belt 2, and the small material conveyor belt 3.

[0028] The hydraulic adjustment device 9 at the lower end of the large material conveyor belt 1, the medium material conveyor belt 2, and the small material conveyor belt 3 can adjust the feeding angle of the conveyor belt, thereby facilitating the feeding of materials to the corresponding downstream.

[0029] Furthermore, a main unit and a hydraulic station are installed on the front side of the multi-stage conveying device.

[0030] The conveying device is located between the screening device 4 and the hydraulic station, which can effectively balance the center of gravity of the screening machine, making the movement and operation of the screening machine more stable.

[0031] Working principle: The conveying device includes a large material conveyor belt 1, a medium material conveyor belt 2, and a small material conveyor belt 3, which are used to output the screened large-diameter material, medium-diameter material, and small-diameter material, respectively. During operation, the small, medium, and large materials decrease in sequence. The small material conveyor belt 3 is set separately on one side of the screening machine, while the large material conveyor belt 1 and the medium material conveyor belt 2 are set on the other side of the screening machine. This can effectively balance the weight of the materials, so that the center of gravity of the equipment falls in the middle of the screening machine during operation, making the center of gravity of the screening machine stable. At the same time, the small material conveyor belt 3 is set separately and placed at the bottom layer. On the one hand, it is compatible with the screening device 4, which can effectively connect with the material of the screening device 4. On the other hand, it helps to lower the center of gravity and make the equipment more stable.
