Description

Technical Field

[0001] The invention belongs to the technical field of sand and stone crushing equipment, and in particular relates to a sand and stone crushing device for construction and a crushing method thereof. Background Art

[0002] In the field of construction, sand and gravel are indispensable basic materials. However, the sand and gravel obtained from the raw material collection site are often of different sizes, including large stones and particles of various sizes. In the construction process, different construction links have specific and strict requirements for the particle size of sand and gravel. For example, concrete pouring requires sand and gravel with a specific particle size range to ensure the strength, fluidity and density of concrete. There are also corresponding standards for the uniformity and size of sand and gravel particles in road base paving. If sand and gravel with too large or too small particle size are used directly without proper treatment, it will seriously affect the quality and stability of the construction project.

[0003] Traditional sand and gravel crushing devices usually adopt a relatively fixed crushing structure and mode, which makes it difficult to flexibly adapt to the crushing needs of sand and gravel of different sizes. Some early crushing equipment was only designed for sand and gravel within a certain particle size range. When faced with mixed sand and gravel with large differences in particle size, they either could not effectively crush large pieces of sand and gravel, resulting in incomplete crushing and affecting subsequent construction processes; or they over-crushed smaller-sized sand and gravel, causing energy waste and producing a large amount of fine sand that does not meet the requirements, increasing the cost and difficulty of sand and gravel screening and processing. Moreover, when dealing with sand and gravel of different hardness and characteristics, a single crushing method is also prone to problems such as low crushing efficiency and severe equipment wear, further reducing the service life of the equipment and overall operational reliability, and increasing the risk of construction costs and construction delays.

[0004] With the rapid development of the construction industry, the requirements for sand and stone quality and crushing device performance are increasing day by day.

DETAILED DESCRIPTION

[0032] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0033] Embodiment 1: This embodiment provides a sand and stone crushing device for construction, comprising: Base 1; a discharge bin 2 is fixedly mounted on the base 1, and a crushing bin 3 is fixedly mounted on the discharge bin 2; Figure 1 — Figure 3 As shown, the base 1 is the installation foundation of the crushing device, the discharge bin 2 is fixedly connected to the base 1 , the crushing bin 3 is fixedly connected to the discharge bin 2 , and the discharge bin 2 is located between the crushing bin 3 and the base 1 .

[0034] The crushing mechanism 4 is installed on the crushing bin 3. The crushing mechanism 4 includes a first crushing part 41 and a second crushing part 42. The first crushing part 41 and the second crushing part 42 are used to crush sand and stone; as shown in FIG. Figure 4 As shown, the first crushing part 41 is located above the crushing chamber 3 , the second crushing part 42 is located below the crushing chamber 3 , and the second crushing part 42 is located inside the crushing chamber 3 .

[0035] The power mechanism 5 includes a first transmission part 53 and a second transmission part 54. The first transmission part 53 is used to provide power to the first crushing part 41, and the second transmission part 54 is used to provide power to the second crushing part 42 and the discharging mechanism 7; as shown in FIG. Figure 5 , Figure 7 , Figure 8 As shown, the power mechanism 5 is installed outside the crushing chamber 3 , the first transmission part 53 is located above the crushing chamber 3 , and the second transmission part 54 is located below the crushing chamber 3 .

[0036] The distance adjustment mechanism 6 includes a first adjustment portion 64 and a second adjustment portion 65, wherein the first adjustment portion 64 is used to adjust the first crushing portion 41, and the second adjustment portion 65 is used to adjust the second crushing portion 42; The discharging mechanism 7 is used for discharging materials. Figure 6 As shown, the discharging mechanism 7 is installed on the discharging bin 2 and is located below the crushing bin 3. The discharging mechanism 7 is used to transport the crushed sand and gravel out for easy collection.

[0037] The first crushing part 41 comprises two symmetrically arranged crushing rollers, each of which is provided with crushing teeth; As shown in FIG. 2 and FIG. 3 , when the sand and gravel are crushed, the sand and gravel to be crushed are transported to the top of the crushing bin 3 by the conveying equipment, and then the two crushing rollers rotate to crush the sand and gravel.

[0038] The second crushing part 42 includes a triangular cone 425, on which a plurality of arc grooves 421 are arranged in a circular pattern. A conical barrel 44 is arranged on the outer side of the triangular cone 425. The cross section of the conical barrel 44 is trapezoidal. A plurality of crushing balls 45 are arranged on the conical barrel 44. The crushing balls 45 can rotate relative to the conical barrel. The conical barrel 44 is fixedly installed inside the crushing bin 3 through the material guide barrel 43.

[0039] like Figure 4 , Fig.11 , Fig.12 , Fig.13 , Fig.15As shown, when the sand and gravel crushed by the first crushing part 41 falls to the position of the second crushing part 42, the sand and gravel with smaller volume will fall below the crushing bin 3 through the arc groove 421 on the triangular cone 425, and fall into the U-shaped plate 75 through the discharge port; the sand and gravel with larger volume will fall between the triangular cone 425 and the conical barrel 44. At this time, as the second crushing part 42 rotates, the triangular cone 425 will rub and crush the sand and gravel again together with the crushing balls 45 on the conical barrel 44. In this way, the sand and gravel are crushed, and the crushed sand and gravel are uniformly collected by falling into the U-shaped plate 75 through the discharge port.

[0040] A spline shaft 422 is fixedly installed below the triangular cone 425, and a sliding groove 424 and at least two spline grooves 423 are provided on the spline shaft 422. The spline grooves 423 form a spline fit with the crushing chamber 3, and one spline groove 423 is slidably fitted with the scraper 46 along the central axis direction of the spline shaft 422. The scraper 46 is slidably fitted with the retaining ring 47, and the retaining ring 47 is fixedly installed inside the crushing chamber 3.

[0041] Specifically, a cylinder can be sleeved at the center of the bottom of the crushing bin 3, and the cylinder and the crushing bin 3 are rotatably matched, and the spline groove 423 forms a spline match with the cylinder, so that the spline shaft 422 can rotate and slide up and down relative to the crushing bin 3.

[0042] The first transmission part 53 includes a bevel gear 531, which is connected to a power source 1 and fixedly mounted on a rotating shaft 532. The rotating shaft 532 is rotatably mounted on the crushing bin 3. Second bevel gear sets 533 are respectively arranged at both ends of the rotating shaft 532. The second bevel gear set 533 is connected to a third bevel gear set 534 through an intermediate shaft. The third bevel gear set 534 is connected to a rotating shaft 535 rotatably mounted on the crushing bin 3. Two transmission gears 536 are fixedly mounted on the rotating shaft 535. The transmission gear 536 is meshed with the transmission gear 537. The transmission gear 537 is fixedly connected to two crushing rollers on the crushing bin 3.

[0043] like Figure 1 — Figure 8 As shown, when the sand and stone are crushed by the crushing roller, the crushing roller needs to be rotated. Specifically, when the power source 1 drives the bevel gear 1 531 to rotate, the bevel gear 1 531 will drive the third bevel gear set 534 to rotate, thereby driving the third bevel gear set 534 to rotate through the second bevel gear set 533, and the third bevel gear set 534 makes the rotating shaft 2 535 rotate, and the transmission gear 1 536 fixedly mounted on the rotating shaft 2 535 will make the transmission gear 2 537 meshing with the transmission gear 1 536 rotate. Since the transmission gear 2 537 is fixedly connected to the shaft where the crushing roller is located, the crushing roller will rotate at this time to complete the crushing of the sand and stone.

[0044] The second transmission part 54 includes a bevel gear 2 541, which is connected to a power source 1, and is fixedly mounted on a transmission shaft 3 542. The transmission shaft 3 542 is rotatably mounted on the crushing bin 3, and the transmission shaft 3 542 is connected to a transmission shaft 4 544 through a belt assembly 1 543. The transmission shaft 4 544 is rotatably mounted on the crushing bin 3. The transmission shaft 4 544 is connected to a vertical shaft 546 through a fourth bevel gear set 545, and the vertical shaft 546 is rotatably mounted on the crushing bin 3. The vertical shaft 546 is connected to a spline shaft 422 through a belt assembly 3 547, and the vertical shaft 546 is connected to a discharging mechanism 7.

[0045] like Figure 1 — Figure 4 as well as Fig.15 As shown, when the bevel gear 2 541 rotates, the bevel gear 2 541 drives the transmission shaft 3 542 to rotate, the transmission shaft 3 542 drives the transmission shaft 4 544 to rotate through the belt assembly 1 543, the transmission shaft 4 544 drives the vertical shaft 546 to rotate on the crushing bin 3 through the fourth bevel gear set 545, the belt assembly 3 547 connected to one end of the vertical shaft 546 away from the fourth bevel gear set 545 drives the spline shaft 422 to rotate on the crushing bin 3, and at this time, the triangular cone 425 will rotate relative to the conical barrel 44, thereby completing the re-extrusion and crushing of sand and gravel through the triangular cone 425 and the crushing ball 45.

[0046] like Figure 5 As shown, in this embodiment, the power source 1 includes a motor 1 51 fixedly mounted on the crushing chamber 3, and a first bevel gear set 52 is fixedly mounted on the output shaft of the motor 1 51. The first bevel gear set 52 is meshed with a bevel gear 1 531 and a bevel gear 2 541; when the output shaft of the motor 1 51 drives the first bevel gear set 52 to rotate, the bevel gear 1 531 and the bevel gear 2 541 will rotate. In addition, as Figure 5 , Figure 6 and Figure 7 As shown, as the prior art, the second bevel gear set 533, the third bevel gear set 534 and the fourth bevel gear set 545 each include a driving bevel gear and a driven gear, the driving bevel gear and the driven bevel gear are meshed together, and the belt assembly 1 543 includes two pulleys and a belt, and the pulleys are connected by belts.

[0047] Embodiment 2. This embodiment is further optimized on the basis of embodiment 1. The parts identical to the aforementioned technical solutions will not be described in detail herein. The first adjusting portion 64 comprises two symmetrically arranged threaded frames 641. The threaded frames 641 are threadedly connected to the power source 2. The threaded frames 641 are slidably matched with a guide plate 642 fixedly mounted on the crushing bin 3. A horizontal frame 643 is fixedly mounted on the end of the threaded frame 641 away from the power source 2. A driving block 644 is fixedly mounted on both sides of the horizontal frame 643. A return groove 1 645 is provided on the driving block 644. The return groove 1 645 is slidably matched with the central axis where the crushing roller is located, and the central axis where the crushing roller is located is slidably matched with the return groove 2 646. The return groove 2 646 is provided on the crushing bin 3.

[0048] like Fig. 9 , Fig.10 As shown, in the process of crushing sand and gravel, the volume of the crushed sand and gravel needs to be adjusted according to different needs, so first of all, the distance between the two crushing rollers needs to be adjusted. Specifically, when it is necessary to crush sand and gravel with a larger volume, the threaded frame 641 is driven by power source 2 to slide upward along the guide plate 642 fixedly installed on the crushing bin 3, so that the horizontal frame 643 slides upward. At this time, the driving blocks 644 connected on both sides of the horizontal frame 643 will rise, and the side of the crushing roller axially away from the threaded frame 641 can be driven to slide along the return groove 2 646 through the return groove 1 645, so that the distance between the two crushing rollers will increase, thereby producing larger crushed sand and gravel.

[0049] The second adjustment part 65 includes two symmetrically arranged vertical frames 651, one end of the vertical frame 651 is threadedly connected to the power source 2, the other end of the vertical frame 651 is rotationally matched with the connecting head, the connecting head is slidingly matched with the return groove 3 653 on the flip rod 652, the flip rod 652 is rotationally matched with the fixed frame 654, the fixed frame 654 is fixedly installed on the crushing bin 3, the end of the flip rod 652 away from the return groove 3 653 is rotationally connected to the lifting ring 655, and the lifting ring 655 is rotationally matched with the sliding groove 424.

[0050] As shown in Figure 3, Figure 4 , Fig.11 , Fig.12 , Fig.13 , Fig.15As shown, in the process of crushing sand and stone, it is also necessary to adjust the volume of the sand and stone after being crushed by the second crushing part 42, that is, the first crushing part 41 and the second crushing part 42 cooperate with each other. Specifically, power source 2 is connected to the vertical frame 651. During the upward movement of the threaded frame 641, the vertical frame 651 will also move upward, so that the connecting head connected to the vertical frame 651 will move upward, and the connecting head is connected to the return groove 3 653 on the flip rod 652, so the end of the flip rod 652 close to the vertical frame 651 will rise. Due to the existence of the return groove 3 653, the flip rod 652 will not be interfered with, so the flip rod 652 rotates relative to the fixed frame 654, so that the end of the flip rod 652 close to the lifting ring 655 will descend. The lifting ring 655 is installed on the sliding groove 424, so the descent of the lifting ring 655 will drive the spline shaft 422 and the triangular cone 425 to descend, and the pulley at the connection between the spline shaft 422 and the belt assembly 3 547 is also spline-matched, so the descent of the spline shaft 422 will not be interfered with by the belt assembly 3 547. When the triangular cone 425 descends, since the cross-section of the conical barrel 44 is trapezoidal, as the triangular cone 425 descends, the distance between the edge line of the cross-section below the triangular cone 425 and the inner wall of the conical barrel 44 will increase, so that larger sand and gravel will fall from between the triangular cone 425 and the conical barrel 44, thereby increasing the volume of the crushed sand and gravel.

[0051] The spline groove 423 and the scraper 46 slide together along the central axis of the spline shaft 422, so when the spline shaft 422 rotates, the spline groove 423 will drive the scraper 46 to rotate. The function of the scraper 46 is to push the sand and gravel that fall under the crushing bin 3 into the discharge port. The function of the retaining ring 47 is to limit the lifting and lowering of the scraper 46 so that the scraper 46 will not move up and down with the spline shaft 422 due to inertia.

[0052] like Fig. 9 As shown, in this embodiment, the power source 2 includes a motor 2 61 fixedly mounted on the crushing bin 3, the output shaft of the motor 2 61 is connected to the belt assembly 2 62, both ends of the belt assembly 2 62 are connected to the threaded rod 63 rotatably mounted on the crushing bin 3, the threaded rod 63 forms a threaded fit with the threaded frame 641 and the vertical frame 651, and the threaded direction of the threaded frame 641 and the vertical frame 651 is the same. The belt assembly 2 62 includes a pulley and a belt, the pulleys are connected by a belt, two pulleys are mounted on two threaded rods 63, and one pulley is mounted on the output shaft of the motor 2 61.

[0053] Embodiment 3: This embodiment is further optimized on the basis of embodiment 1. The same parts as the above technical solutions will not be repeated here. The discharge mechanism 7 includes a U-shaped plate 75. One end of the U-shaped plate 75 is rotatably connected to the discharge bin 2. A discharge port is provided above the portion of the U-shaped plate 75 located inside the discharge bin 2. The discharge port is arranged on the crushing bin 3 (such as Fig.13As shown in the figure, a vibration component is arranged under the U-shaped plate 75. When the crushed sand and gravel fall onto the U-shaped plate 75 through the discharge port, the vibration component drives the U-shaped plate 75 to vibrate, so as to improve the sand and gravel collection efficiency.

[0054] The vibration assembly includes a reset spring 76 and a cam 74. One end of the reset spring 76 is fixedly connected to the U-shaped plate 75, and the other end of the reset spring 76 is fixedly connected to the discharge bin 2. The cam 74 is connected to the sixth bevel gear set 73 through a transmission shaft. The sixth bevel gear set 73 is connected to one end of the discharge shaft 72, and the other end of the discharge shaft 72 is connected to the fifth bevel gear set 71. The fifth bevel gear set 71 is connected to the vertical shaft 546.

[0055] like Figure 3 , Figure 6 , Fig.12 As shown, when the vertical shaft 546 rotates, it will drive the fifth bevel gear set 71 to rotate, so that the fifth bevel gear set 71 drives the discharge shaft 72 to rotate inside the discharge bin 2, and the discharge shaft 72 drives the cam 74 to rotate through the guide barrel 43. The cam 74 is located below the U-shaped plate 75, and the cam 74 and the U-shaped plate 75 slide together. In this way, since the cam 74 is an irregular shape, when the protruding and smooth parts of the cam 74 alternately contact the U-shaped plate 75, the U-shaped plate 75 will reciprocate upward and downward on the discharge bin 2, thereby increasing the speed of the sand and gravel moving of the U-shaped plate 75 after crushing, and improving the collection efficiency. The function of the reset spring 76 is to assist the reset of the U-shaped plate 75.

[0056] In addition, the present invention also provides a crushing method of a sand and stone crushing device for construction, comprising the following steps: Step 1: Start the power source 1, which drives the first transmission part 53 and the second transmission part 54 to transmit.
