Description

Technical Field

[0001] This invention relates to the field of building material transportation technology, specifically to a transportation equipment for processing building materials. Background Technology

[0002] In the field of building materials processing, such as when stone is commonly used as raw material for sand making, existing equipment usually uses conveying equipment to directly transport the stone from the ground to the top of the crushing device for dumping and sand making. However, the stone has a large particle size distribution before sand making, and it originally contains some components that meet the particle size requirements of the crushed sand. If the stone that already meets the particle size requirements is then sent into the crushing device together with other larger stones, it will undoubtedly result in a waste of costs and be detrimental to the environment. Summary of the Invention

Moreover, the screening particle size of the screening roller can be freely adjusted. This solves the problem mentioned in the background art that the existing tower sand making machine usually directly transports the stone to the crushing device for sand making. However, the stone has a large particle size difference before sand making. It originally contains some components that meet the particle size requirements of the crushed sand and gravel.

[0025] 1. This building material processing transportation equipment adds two steps, a screening mechanism and a third belt conveyor, between the existing first belt conveyor and building material processing equipment. The screening mechanism uses several screening rollers to form gaps to screen the stone material conveyed by the first belt conveyor. Larger stones fall into the building material processing equipment through the third belt conveyor for crushing, while smaller stones fall into the building material processing equipment through branch pipes. They can be directly transported out with the crushed stone material, or the crushing time of this part of the stone material can be reduced, thereby achieving the environmental protection goals of saving production costs and reducing wear on the crushing equipment.

[0026] 2. The conveying equipment for processing building materials has several movable screening rollers used for screening stone, which allows for adjustment of the gap size between the screening rollers, thereby adjusting the particle size according to actual production needs.

[0027] 3. In this building material processing conveying equipment, when moving several screening rollers to adjust the gap size for screening, not only does the middle screening roller move to adjust the gap between the screening rollers, but all the screening rollers move synchronously together, and the displacement of the screening rollers decreases from the sides towards the center. This results in changes not only in the gap size between the screening rollers themselves, but also in the gap size between the screening rollers on both sides and the first and third belt conveyors, thereby improving screening efficiency.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1, please refer to Figures 1-7 A building material processing transportation device includes a base 100, on which a first belt conveyor 200 and a building material processing device 300 are provided. The first belt conveyor 200 is used to feed materials into the building material processing device 300.

[0039] The base 100 is also provided with a third belt conveyor 600 and a screening mechanism 700. The third belt conveyor 600 is located between the first belt conveyor 200 and the building material processing equipment 300, and the screening mechanism 700 is located between the third belt conveyor 600 and the first belt conveyor 200.

[0040] The screening mechanism 700 includes a plurality of screening rollers 710 rotatably mounted on the base 100. The plurality of screening rollers 710 are arranged in an inverted V-shape, and the stone is screened and filtered out of the sand and gravel in the stone through the gaps between the plurality of screening rollers 710.

[0041] The building material processing equipment 300 is equipped with a feed inlet 310 and a discharge outlet 320, and the third belt conveyor 600 is aligned with the feed inlet 310.

[0042] The building material processing equipment 300 is also equipped with a branch pipe 330. One end of the branch pipe 330 is aligned with several screening rollers 710, and the other end of the branch pipe 330 is connected to the discharge port 320.

[0043] In this embodiment: Stone is selected as the raw material for building material processing in this device. Existing devices do not screen the stone before crushing it. Due to the large variation in particle size of the stone, there are naturally some smaller or uncrushable gravel particles in the stone. These gravel particles are fed into the crushing device along with the larger stone particles, which not only wastes production and requires the crushing device to run for an extra time, but is also not environmentally friendly. In addition, the smaller gravel particles also increase the wear and tear on the crushing device.

[0044] Firstly, the first belt conveyor 200 is inclined and used to transport stones. The part of the first belt conveyor 200 near the bottom of the base 100 is also equipped with a funnel for holding stones. After the stones are poured into the funnel, the stones can be continuously transported from the ground upward by the operation of the first belt conveyor 200.

[0045] The improvement of this device is that, based on the tower-type transport and processing equipment shown in the figure, a third belt conveyor 600 is added between the first belt conveyor 200 and the building material processing equipment 300, and a screening mechanism 700 is added between the first belt conveyor 200 and the third belt conveyor 600.

[0046] After the stone reaches the top of the belt structure of the first belt conveyor 200, it continues to be conveyed and falls back onto several screen rollers 710 arranged in an inverted V shape. During the process of the stone passing through an inverted V-shaped trajectory, the size of the gaps between the screen rollers 710 is set to meet the filtering of sand and gravel, so that the smaller particles of the stone pass through the gaps and fall down, while the larger particles of the stone fall onto the third belt conveyor 600, and are continued to be conveyed by the belt structure of the third belt conveyor 600 and finally fall from the feed inlet 310 into the building material processing equipment 300, where they are crushed by the crushing mechanism 500 to form sand and gravel.

[0047] The sand and gravel that leak through the gaps of several screening rollers 710 enter the building material processing equipment 300 through the branch pipe 330, merge with the sand and gravel formed by the crushing mechanism 500, and finally flow out through the discharge port 320 to the second belt conveyor 400, where it is transported away by the belt structure of the second belt conveyor 400 for the next step of sand making.

[0048] It should be further explained that, firstly, the lower opening of the branch pipe 330 can be optionally located below the roller crusher 510, so that the sand and gravel conveyed into the building material processing equipment 300 by the branch pipe 330 does not contact the roller crusher 510. Alternatively, the lower outlet of the branch pipe 330 can be set higher, so that the sand and gravel conveyed into the building material processing equipment 300 by the branch pipe 330 is also crushed by the roller crusher 510. However, unlike the stone material introduced from the top, the smaller stone material in this part is crushed in a shorter time to meet the particle size requirements, which also plays an environmental protection role in separating and processing according to different particle sizes.

[0049] Secondly, the first belt conveyor 200, the second belt conveyor 400 and the third belt conveyor 600 are based on conventional existing technology, and their principles will not be described in detail. Their specific structures are all achieved by a motor-driven belt structure installed on the base 100.

[0050] Example 2, for details please refer to Figures 2-7 The building material processing equipment 300 is equipped with a feed inlet 310 and a discharge outlet 320, and the third belt conveyor 600 is aligned with the feed inlet 310.

[0051] The building material processing equipment 300 is also equipped with a branch pipe 330. One end of the branch pipe 330 is aligned with several screening rollers 710, and the other end of the branch pipe 330 is connected to the discharge port 320.

[0052] The base 100 has several straight grooves 720, and several screening rollers 710 are slidably connected in the several straight grooves 720 respectively;

[0053] The screening mechanism 700 also includes a drive assembly 730 and an adjustment assembly 740. The drive assembly 730 is used to drive a plurality of screening rollers 710 to rotate synchronously, and the adjustment assembly 740 is used to adjust the height of the plurality of screening rollers 710 to adjust the screening particle size of the material.

[0054] The adjustment assembly 740 includes a first motor 741 disposed on the base 100. A turntable 742 is coaxially disposed on the output shaft of the first motor 741. The turntable 742 is provided with a first arc-shaped slide groove 743 and a plurality of second arc-shaped slide grooves 744.

[0055] The number of screening rollers 710 is odd. The screening roller 710 in the middle is slidably connected in the first arc-shaped groove 743, and the screening rollers 710 on both sides are slidably connected in the second arc-shaped groove 744 respectively.

[0056] The curvature of the first arc-shaped groove 743 is smaller than that of the second arc-shaped groove 744.

[0057] In this embodiment, the size of the screening particle size is adjustable to adapt to the specific raw material particle size, sand making requirements, crushing device power, etc.

[0058] exist Figure 1 and Figure 2 Based on the existing structure, firstly, a belt extends from the front and rear sides between the first belt conveyor 200 and the third belt conveyor 600. Figure 4 The base 100 structure is shown in the figure. To the left of the screening mechanism 700 is a first belt conveyor 200 mounted on the base 100, and to the right is a third belt conveyor 600 mounted on the base 100.

[0059] First, three screening rollers 710 are set, but other odd numbers can also be used. The belt structure of the first belt conveyor 200 is attached to the screening roller 710 on the left and is located slightly lower. The belt structure of the third belt conveyor 600 is attached to the screening roller 710 on the right and is located slightly lower.

[0060] The front end of the screening roller 710 is slidably installed in the straight chute 720. The front end of the screening roller 710 has a T-shaped cross-section, and the straight chute 720 is a groove shape distributed vertically. The straight chute 720 serves to both allow the screening roller 710 to slide and rotate, and also to limit its movement. The stone material conveyed to the right by the first belt conveyor 200 is conveyed to the right by the friction of the three screening rollers 710 and then falls onto the third belt conveyor 600, completing the screening process.

[0061] Furthermore, the rear end of the screening roller 710 is supported by a turntable 742. When adjusting the spacing of several screening rollers 710 to adjust the particle size being screened, not only does the upward movement of the middle screening roller 710 increase or decrease the spacing between the middle screening roller 710 and the two screening rollers 710 on the left and right sides, but also the spacing between the screening rollers 710 on the left and right sides and the first belt conveyor 200 or the third belt conveyor 600 increases or decreases. By changing the spacing of all screening gaps, the screening efficiency is improved.

[0062] Specifically, such as Figure 6 As shown, if all three screening rollers 710 are located at the position furthest from the center of the turntable 742 in the first arc-shaped chute 743 or the second arc-shaped chute 744, the turntable 742 will rotate clockwise via the operation of the first motor 741. This will cause the middle screening roller 710 to slide along the first arc-shaped chute 743 and its front end to slide downwards due to the limiting effect of only being able to move up and down along the straight chute 720. The screening rollers 710 on the left and right sides will also slide downwards in the same way.

[0063] Furthermore, since the curvature of the first arc-shaped groove 743 is smaller than that of the second arc-shaped groove 744, after the first motor 741 drives the turntable 742 to rotate clockwise by a certain angle, the middle screening roller 710 moves down more along the first arc-shaped groove 743, while the left and right screening rollers 710 move down less. This reduces the gap between the three screening rollers 710 by increasing the displacement between the middle screening roller 710 and the left and right screening rollers 710.

[0064] It should be noted that the screening rollers 710 can be set to other odd numbers, such as five screening rollers 710. In this case, two more symmetrical arc-shaped grooves should be added, and the curvature of the arc-shaped grooves should be greater than that of the second arc-shaped groove 744.

[0065] Example 3, for details please refer to Figures 4-8 The drive assembly 730 includes a plurality of first rotating rods 731 and a plurality of second rotating rods 732. The plurality of first rotating rods 731 are rotatably mounted on the base 100. The plurality of second rotating rods 732 are respectively connected to a plurality of screening rollers 710. The plurality of second rotating rods 732 are respectively slidably connected to the plurality of first rotating rods 731.

[0066] Each of the several second rotating rods 732 is provided with a first bevel gear 733, and each of the several screening rollers 710 is provided with a second bevel gear 734, and the several second bevel gears 734 respectively mesh with the several first bevel gears 733;

[0067] The drive assembly 730 also includes a plurality of third rotating rods 735 rotatably mounted on the base 100. A second motor 736 is mounted on the base 100, and the output shaft of the second motor 736 is coaxially connected to one of the third rotating rods 735.

[0068] Each of the first rotating rods 731 is provided with a third bevel gear 737, and each of the third rotating rods 735 is provided with a fourth bevel gear 738, and the fourth bevel gears 738 mesh with the third bevel gears 737 respectively.

[0069] In this embodiment, the first rotating rod 731 and the second rotating rod 732 are rotatably mounted on the base 100. The upper end of the first rotating rod 731 has a rectangular opening, while the lower part of the second rotating rod 732 is rectangular. The rectangular part of the second rotating rod 732 is slidably mounted in the upper opening of the first rotating rod 731, so that the rotation of the first rotating rod 731 can drive the rotation of the second rotating rod 732 without affecting the lifting and lowering of the second rotating rod 732. Specifically, the second rotating rod 732 is connected to the screening roller 710 in the following way: the upper part of the second rotating rod 732 is a cylinder with a T-shaped cross-section. This cylindrical part is rotatably mounted on the lower end of the connecting seat 800, which is rotatably mounted on the surface of the screening roller 710. Thus, when the screening roller 710 lifts and lowers, it will move the second rotating rod 732 and the first bevel gear 733 together. The limiting position of the first rotating rod 731 ensures that when the screening roller 710 rotates, the connecting seat 800 also rotates, keeping the groove at its lower end that allows the second rotating rod 732 to rotate always facing downwards.

[0070] During operation, the second motor 736 drives one of the third rotating rods 735 to rotate, which in turn causes all three third rotating rods 735 to rotate through the transmission of the two belt drive devices 739. Then, the transmission direction is changed by the three fourth bevel gears 738 and the three third bevel gears 737, which drive the three first rotating rods 731 and the three second rotating rods 732 to rotate. Finally, the transmission direction is changed by the three first bevel gears 733 and the three second bevel gears 734, which drive the three screening rollers 710 to rotate.

[0071] Example 4, for details please refer to Figures 1-3 The base 100 is also equipped with a second belt conveyor 400. The building material processing equipment 300 is equipped with a crushing mechanism 500 for crushing stone to generate gravel. The second belt conveyor 400 is used to deliver the gravel. The second belt conveyor 400 is aligned with the discharge port 320.

[0072] The crushing mechanism 500 includes a roller crushing device 510 installed in the building material processing equipment 300;

[0073] The crushing mechanism 500 also includes a first rotating shaft 520 rotatably disposed within the building material processing equipment 300, on which a crushing jaw 530 is disposed, and the crushing jaw 530 is elastically connected to the inner wall of the building material processing equipment 300 via a spring 540.

[0074] A push rod 550 is slidably installed inside the building material processing equipment 300. One end of the push rod 550 is connected to a reciprocating component 560, and the other end of the push rod 550 is movably hinged to the crushing jaw 530 through a hinge shaft.

[0075] The reciprocating assembly 560 includes two second rotating shafts 561 rotatably disposed within the building material processing equipment 300. A third motor 562 is provided on the building material processing equipment 300, and the output shaft of the third motor 562 is coaxially connected to one of the second rotating shafts 561.

[0076] Each of the two second rotating shafts 561 is equipped with a spur gear 563, which meshes with each other. Each of the two second rotating shafts 561 is equipped with a half gear 564, and the teeth of the two half gears 564 are in opposite directions. A rack 565 is provided on the push rod 550, and the rack 565 meshes with both half gears 564.

[0077] In this embodiment, the roller crusher 510, being existing technology, will not be described in detail. It crushes stone through the relative rotation of its two crushing rollers. Furthermore, before using the roller crusher 510, a third motor 562 drives two spur gears 563 to rotate in opposite directions, causing two half-gears 564 to alternately mesh with the rack 565. This, in turn, drives the rack 565 and push rod 550 to move back and forth, thereby driving the crushing jaw 530 to rotate reciprocally. Large pieces of stone are repeatedly crushed before falling into the roller crusher 510, thus facilitating subsequent crushing.

[0078] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0079] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
