Description

Technical Field

[0001] The utility model belongs to the technical field of material feeding devices, in particular to a stone material conveying and feeding device. Background Art

[0002] The history of stone transportation can be traced back to the Industrial Revolution, when it was mainly carried out by simple conveyor belts, chutes or bucket elevators pulled by human or animal power for short-distance and inefficient transportation. With the widespread application of mechanical power, conveying equipment has gradually become mechanized, and belt conveyors, screw conveyors, chain conveyors, etc. have appeared. These devices can achieve large-scale, continuous and relatively efficient stone transportation.

[0003] During the stone transportation process, some fine particles will adhere to the conveyor belt. During the transmission process, the conveyor belt will increase its own gravity and cause damage to the conveyor belt. In addition, during the long-term stone transportation process, the conveyor belt is prone to tension and relaxation, which will affect the subsequent stone transportation.

[0004] Therefore, when conveying stones, after the stones are unloaded, the fine particles adhering to the conveyor belt should be cleaned in time to reduce the gravity on the conveyor belt. At the same time, the upper transport part of the conveyor belt should be protected to avoid the conveyor belt from loosening too quickly. A stone conveying and unloading device is needed to solve the existing problems. Utility Model Content

[0005] In view of this, the utility model aims to solve the shortcomings of the prior art and provide a stone conveying and unloading device, which uses auxiliary drive rollers to assist the conveying roller group to transport stones, thereby preventing the conveyor belt from loosening too quickly, and uses brush rollers to clean fine particles on the surface of the conveyor belt in time, thereby avoiding excessive pressure on the conveyor belt itself and protecting the conveyor belt.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a stone conveying and unloading device, including a support frame, a conveying roller group is fixedly installed on the support frame, and a conveyor belt is connected to the transmission roller group, that is, the conveyor belt conveys the stone, and an auxiliary transmission roller located on the support frame is also installed between the transmission roller groups, that is, the auxiliary transmission roller supports the bottom of the conveyor belt that conveys the material, a bearing base is installed on the inner side wall of the end of the support frame, and a brush roller is installed between the two bearing bases. When the conveyor belt finishes conveying the stone, the brush roller cleans the surface of the conveyor belt. A tensioning assembly located on the support frame is also installed on the transmission roller at one end of the transmission roller group, that is, the tensioning assembly tensions the conveyor belt.

[0007] The tensioning assembly includes a telescopic push rod, the end of which is connected to a sliding connection block, and the upper and lower parts of the sliding connection block are connected to slide grooves, that is, the sliding connection block drives the driven transmission roller to move on the slide groove, that is, the slide groove limits the sliding connection block.

[0008] A plurality of L-shaped support rods are also arranged on the support frame, and a baffle plate located above the conveyor belt is installed on the L-shaped support rod, and a feed port is also connected to the top of the baffle plate, that is, the baffle plate shields the stones above the conveyor belt.

[0009] Drive motors are installed at the ends of the brush roller and the conveying roller group. The output shaft of the drive motor is connected to the active conveying roller on the conveying roller group, that is, the drive motor drives the conveying roller group and the brush roller to rotate respectively.

[0010] The sliding connection block is also provided with a locking hole, and the telescopic end of the telescopic push rod is installed with a bolt, that is, the locking hole is connected to the sliding connection block through the bolt, and the sliding connection block is controlled to drive the driven conveying roller to move and tighten the conveyor belt.

[0011] A U-shaped support plate is horizontally arranged on the support frame, that is, the U-shaped support plate supports the middle part of the support frame.

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

[0013] Firstly, the auxiliary transmission roller supports the bottom of the conveyor belt that transports the materials, avoids the parts between the conveyor roller groups from being suspended in the air, reduces the excessive pressure caused by stone particles on the conveyor, avoids the conveyor belt from being loosened or damaged too quickly, and protects the conveyor belt.

[0014] Secondly, the brush roller cleans the surface of the conveyor belt to prevent small particles of stone from being retained on the surface of the conveyor belt, thereby reducing excessive pressure on the conveyor belt during the conveying process.

[0015] Thirdly, the sliding connection block drives the driven transmission roller to move on the slide. When the conveyor belt is too loose or tight, the telescopic push rod is started to tighten the conveyor belt to prevent the conveyor belt from being too tight or too loose, protect the conveyor belt, and ensure the normal transportation of stones.

In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0024] like Figure 1-3 As shown, a stone conveying and unloading device includes a support frame 101, and the support frame 101 is composed of horizontal and vertical crossed plates. A conveying roller group 102 is fixedly installed on the support frame 101, and the conveying roller group 102 is configured as an active transmission roller and a driven transmission roller. A conveyor belt 103 is connected to the transmission roller group, that is, the conveyor belt 103 conveys the stone. Auxiliary transmission rollers 104 located on the support frame 101 are also installed between the transmission roller groups 102. The auxiliary transmission rollers 104 are configured as multiple parallel distributions. The auxiliary transmission rollers 104 are located below the conveyor belt 103 for conveying materials and are tangent to it. That is, the auxiliary transmission rollers 104 support the bottom of the conveyor belt 103 for conveying materials to prevent stone particles from hitting the transmission belt. In order to prevent excessive pressure from being caused by conveying, the conveyor belt 103 may become loose or damaged too quickly. A bearing base 105 is installed on the inner side wall of the end of the support frame 101, and a brush roller 106 is installed between the two bearing bases 105. The brush roller 106 is located below the discharge port of the conveyor belt 103. When the conveyor belt 103 finishes conveying the stones, the brush roller 106 cleans the surface of the conveyor belt 103 to prevent small particles of stones from being retained on the conveyor belt 103. During the conveying process of the conveyor belt 103, excessive pressure on the conveyor belt 103 is caused. A tensioning component 200 located on the support frame 101 is also installed on the conveyor roller at one end of the conveying roller group 102, that is, the tensioning component 200 tensions the conveyor belt 103.

[0025] like Figure 3As shown, the tensioning assembly 200 includes a telescopic push rod 201, which is provided with two telescopic push rods 201 and symmetrically installed. The ends of the telescopic push rods 201 are connected with sliding connection blocks 202, which are sleeved on both ends of the driven conveying rollers of the conveying roller group 102 and are symmetrically arranged. The upper and lower parts of the sliding connection blocks 202 are connected with slide grooves 203, and the slide grooves 203 are fixedly installed on the support frame 101, that is, the sliding connection blocks 202 drive the driven transmission rollers to move on the slide grooves 203 to tension the conveyor belt 103, that is, the slide grooves 203 are connected to the sliding connection blocks 202. The connecting block 202 is limited; a locking hole 204 is also provided on the sliding connection block 202, and a bolt 205 is installed on the telescopic end of the telescopic push rod 201, that is, the locking hole 204 is connected to the sliding connection block 202 through the bolt 205, and the sliding connection block 202 is controlled to drive the driven conveying roller to move, and the conveyor belt 103 is tensioned. The telescopic end of the telescopic push rod 201 is set to a threaded shape, and the tail of the telescopic end of the telescopic push rod 201 passes through the locking hole 204. The bolts 205 on both sides fix the telescopic end of the telescopic push rod 201 to the sliding connection block 202.

[0026] like Figure 1 , 2 As shown, the support frame 101 is also provided with a plurality of L-shaped support rods 301, and a baffle 302 located above the conveyor belt 103 is installed on the L-shaped support rod 301, and the top of the baffle 302 is also connected to the feed port 303, that is, the baffle 302 blocks the stones above the conveyor belt 103 to prevent the stones from falling from the edge of the conveyor belt 103; the ends of the brush roller 106 and the conveyor roller group 102 are both installed with a driving motor 304, and the output shaft of the driving motor 304 is connected to the active conveyor roller on the conveyor roller group 102, that is, the driving motor 304 drives the conveyor roller group 102 and the brush roller 106 to rotate respectively; a U-shaped support plate 305 is horizontally arranged on the support frame 101, that is, the U-shaped support plate 305 supports the middle part of the support frame 101, so that the structure of the support frame 101 can be more stable.

[0027] When the device is used, the drive motor 304 is started to drive the brush roller 106, the conveying roller group 102 and the conveyor belt 103 to rotate, and the stone is placed on the conveyor belt 103. The auxiliary drive roller 104 supports the stone and assists the conveyor belt 103 in driving the stone to be conveyed. When the stone falls from the end of the conveyor belt 103, the brush roller 106 cleans the surface of the conveyor belt 103 to make the fine particles adhering to the conveyor belt 103 fall off, thereby avoiding increasing the gravity of the conveyor belt 103 itself during the conveying process and protecting the conveyor belt 103. When the conveyor belt 103 is too tight or too loose, the symmetrical telescopic push rod 201 is started to drive the sliding connection block 202 to move in the slide groove 203, tighten the conveyor belt 103, and ensure the normal transportation of the stone.
