[0002] The statements in this section are merely intended to provide background information related to the technical solution of the present application to aid understanding, and they do not necessarily constitute prior art for the technical solution of the present application.

[0003] In the prior art, vibrating screens usually adopt a centralized feeding method, and the upper process discharges ore to the vibrating screen mostly through circular pipes. This method has many problems. In the pipeline discharge method, the slurry is discharged from the pipeline at a high speed, directly impacting the screen of the vibrating screen, causing the screen to bear a large impact force, the vibrating screen is partially overloaded, and the screen surface is easily damaged. Frequent replacement of the screen not only increases production costs, but also affects the continuity of production. Centralized feeding through pipelines makes the feed distribution of the vibrating screen uneven. The slurry flow in some areas is large, which easily causes the screen to be blocked; while the slurry flow in other areas is small, and the screening efficiency is low. Uneven feeding will also cause uneven force on the vibrating screen, affecting the stability and service life of the equipment. At the same time, when repairing the vibrating screen, the vibrating screen and the feeding pipeline interfere with each other, and the vibrating screen cannot be lifted quickly, which is time-consuming and labor-intensive. Summary of the invention

[0005] In one embodiment, the cross-sectional area of ​​the upper port of the second section chute is larger than the cross-sectional area of ​​the lower port of the first section chute.

[0006] In one embodiment, the vibrating screen feeding device further comprises: a rubber skirt for shielding provided at the connection between the first section chute and the second section chute.

[0007] In one embodiment, wear-resistant linings are provided inside the first section chute and the second section chute.

[0008] In one embodiment, the wear-resistant lining plate is made of rare earth wear-resistant alloy.

[0009] In one embodiment, the vibrating screen feeding device further comprises: a supporting device for providing support to the first section chute and the second section chute.

[0010] In one embodiment, the position locking device includes a locking pin and a locking hole cooperating with the locking pin, wherein the locking pin is arranged on one of the slideway and the trolley, and the locking hole is arranged on the other of the slideway and the trolley.

[0011] In one embodiment, the chute near the lower port of the second section chute has a certain slope, which ensures that the slurry flows smoothly and at a moderate flow rate.

[0012] In one embodiment, an adjustable valve is provided near the upper port of the first section chute to control the flow of the slurry.

[0016] 2. The dispersed feeding method provided by the rectangular chute effectively reduces the impact of the slurry on the screen, and the service life of the screen is significantly extended. After the transformation, the replacement cycle of the screen is extended from the original 2 months to 10 months, which greatly reduces the production cost and the number of downtime. At the same time, it avoids the impact of leakage after the screen is damaged on the subsequent work sections, ensuring the stable operation of the subsequent operation process.

[0017] 3. The feeding is uniform and the screening efficiency is improved. The dispersed feeding makes the feeding of the vibrating screen more uniform, and the slurry flow rate in each part is basically the same. This not only improves the screening efficiency, but also reduces the possibility of screen blockage. After the transformation, it provides better raw material guarantee for subsequent production links.

[0018] 4. Improved production efficiency. Due to the extended service life of the screen and the improved screening efficiency, equipment downtime and maintenance workload are reduced, thereby improving the production efficiency of the entire production system. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] Figure 1 The present invention is a schematic diagram of the structure of a vibrating screen feeding device according to an embodiment of the present invention. The vibrating screen feeding device includes a discharge device 1 for discharging ore pulp, a first chute 2 fixedly connected to the discharge device 1, a slide, a trolley located on the slide, a position locking device, and a second chute 3 fixed on the trolley. Figure 1 The slideway, trolley and position locking device are not shown)

[0026] The first section chute 2 has a rectangular upper port and a lower port, wherein the upper port is used to receive ore pulp from the ore discharge device 1, and the lower port is used to discharge the ore pulp.

[0027] The second chute 3 has a rectangular upper port and a lower port. The upper port of the second chute 3 is used to receive slurry from the lower port of the first chute 2 , and the lower port of the second chute 3 is used to transport slurry to the vibrating screen 4 .

[0028] The trolley can move along the slideway, thereby driving the second section chute 3 fixed on the trolley to move. The position locking device is used to lock the trolley to a predetermined working position on the slideway. When the trolley is locked to the predetermined working position, the upper port of the second section chute 3 is located below the lower port of the first section chute 2, and the lower port of the second section chute 3 is located above the vibrating screen 4, so that the slurry from the ore discharge equipment 1 can be smoothly transported to the vibrating screen 4, and finally transported through the conveyor belt 5. When the position locking device is unlocked, the trolley can move freely along the slideway, so that the second section chute 3 can leave the vibrating screen 4, which is convenient for the staff to repair and replace the vibrating screen 4.

[0029] The position locking device is used to ensure that the trolley will not shake or shift due to the impact of the slurry on the second chute 3 during operation. The position locking device can be located on the trolley or on the slideway, as long as it can firmly lock the trolley to a predetermined position on the slideway. In one embodiment, the position locking device includes a locking pin and a locking hole that cooperates with the locking pin, the locking pin is provided on one of the slideway and the trolley, and the locking hole is provided on the other of the slideway and the trolley.

[0030] The first section chute 2 can be fixed to the ore discharge device 1 in various feasible ways, for example, the first section chute 2 can be welded to the ore discharge device 1, or the first section chute 2 can be fixed to the ore discharge device 1 with bolts. Regardless of the method used, it is necessary to ensure that the first section chute 2 is firmly and reliably installed and will not shake or shift due to the impact of the slurry. In one embodiment, an adjustable valve is provided near the upper port of the first section chute 2 to control the flow rate of the slurry.

[0031] The first section chute 2 can be fixed on the trolley in various feasible ways. In one embodiment, a locking device can be provided to fix the second section chute 3 in a suitable position on the trolley.

[0032] In one embodiment, see Figure 2 The first section chute 2 is set to have an angle with the vertical direction (that is, inclined), and the angle can be, for example, between 10 and 30 degrees. In one embodiment, the chute near the lower port of the second section chute 3 has a certain slope, which can be set according to actual needs (such as the discharge volume of the discharge equipment 1 and the slurry characteristics, etc.) to ensure that the slurry flows smoothly and at a moderate flow rate, thereby reducing the impact on the screen of the vibrating screen 4.

[0033] The first chute 2 and the second chute 3 have a rectangular cross-sectional shape and a rectangular port, and have a relatively wide transverse length. Since the lower port of the second chute 3 has a relatively wide transverse length, the slurry can be distributed more evenly on different parts of the vibrating screen, avoiding excessive stress on the local part of the vibrating screen, thereby improving the screening efficiency and the service life of the screen.

[0034] In one embodiment, in order to further improve the stability and safety of the first section chute 2 and the second section chute 3, a supporting device for providing support to the first section chute 2 and the second section chute 3 can be provided to ensure that the first section chute 2 and the second section chute 3 will not shake or shift due to the impact of the slurry during operation.

[0035] In one embodiment, the cross-sectional area of ​​the upper port of the second chute 3 is larger than the cross-sectional area of ​​the lower port of the first chute 2, so as to ensure that the slurry can smoothly enter the second chute 3 and prevent the slurry from splashing. In one embodiment, a rubber skirt for shielding can be provided at the connection between the first chute 2 and the second chute 3 to further prevent the slurry from splashing and avoid the risk of leakage.

[0036] In one embodiment, wear-resistant lining plates 6 are provided inside the first section chute 2 and the second section chute 3 to increase the wear resistance of the chute. The material of the wear-resistant lining plates 6 can be a rare earth wear-resistant alloy. In this way, it can be ensured that the chute has sufficient wear resistance and strength to withstand the long-term impact of the slurry and reduce wear, thereby reducing the frequency of maintenance and replacement. In one embodiment, see Figure 2 and Figure 3 The wear-resistant lining 6 can be fixed to the first section chute 2 and the second section chute 3 by bolts, and the wear-resistant lining 6 can be easily replaced when necessary.
