Description

Technical Field

[0001] This utility model relates to the technical field of manufactured sand production, and in particular to a manufactured sand conveying and dispersing device. Background Technology

[0002] Manufactured sand refers to sand processed by sand making machines and other auxiliary equipment. The finished product is more regular and can be processed into sand of different shapes and sizes according to different process requirements, better meeting daily needs. Manufactured sand requires specialized equipment to produce qualified and suitable sand and gravel. A manufactured sand production line consists of equipment such as a vibrating feeder, jaw crusher, sand making machine, vibrating screen, and belt conveyor. Various models of equipment are combined according to different process requirements to meet different customer process requirements. Currently, traditional manufactured sand conveying devices do not have the function of breaking up materials during use, and are prone to blockage during the conveying process, which needs to be improved. Utility Model Content

[0003] The present invention aims to address the aforementioned deficiencies in the prior art by providing a manufactured sand conveying and dispersing device that achieves the purpose of dispersing and preventing agglomeration during the conveying process of manufactured sand.

[0004] The above-mentioned objective of this utility model is achieved through the following technical solution: A manufactured sand conveying and dispersing device includes a belt conveyor, characterized in that: a first guide plate group, a self-rotating dispersing wheel, and a second guide plate group are sequentially arranged on the conveying surface of the belt conveyor along the conveying direction of the manufactured sand; multiple first guide plates in the first guide plate group are respectively mounted on the belt conveyor in a liftable manner through a first screw pair, and a gradually narrowing guide gap is formed between the two outermost first guide plates; both ends of the dispersing wheel are respectively mounted on the belt conveyor in a liftable manner through a screw pair; multiple second guide plates in the second guide plate group are respectively mounted on the belt conveyor in a liftable manner through a second screw pair, and a gradually narrowing guide gap is formed between the two outermost second guide plates.

[0005] By adopting the above technical solution, when the belt conveyor transports manufactured sand, the manufactured sand first passes through the first guide plate group. Because a gradually narrowing guide gap is formed between the two outermost first guide plates, and the first guide plates can be raised and lowered via the first screw pair, the height of the first guide plates and the opening and closing degree of the guide gap can be adjusted according to the conveying volume and particle size of the manufactured sand. This allows the manufactured sand to be guided in an orderly manner upon entry, initially crushing, standardizing, and agglomerating it. Next, the manufactured sand reaches the self-rotating dispersing wheel. The dispersing wheel is vertically and flexibly mounted on the belt conveyor via screw pairs at both ends, and its height can also be adjusted according to the actual situation of the manufactured sand. When the manufactured sand passes through the self-rotating dispersing wheel, the dispersing wheel is subjected to… The conveyed manufactured sand is forced to rotate, which effectively breaks up the sand and separates any clumps, preventing blockages during subsequent conveying. Finally, the sand passes through a second guide plate assembly, which is adjustable via a second screw assembly. A gradually narrowing guide gap is formed between the two outermost guide plates, further guiding and organizing the broken-up sand. This ensures smoother transport of the sand on the belt conveyor, guaranteeing high efficiency and stability throughout the entire process. This adjustable design allows the device to adapt to different working conditions and sand characteristics, making it highly versatile and practical, better meeting the needs of actual production.

[0006] The present invention is further configured such that: a first mounting frame is bridging the belt conveyor; the first screw assembly includes a plurality of first adjusting nuts disposed on the first mounting frame and a first adjusting screw threadedly connected to the first adjusting nuts; and a plurality of first guide plates in the first guide plate assembly are respectively disposed at the bottom ends of these first adjusting screws.

[0007] By adopting the above technical solution, operators can easily drive the first adjusting screw to rise and fall by rotating the first adjusting nut, thereby achieving precise adjustment of the height and tilt direction of the first guide plate. This structural design makes the adjustment process simple and direct, without complicated operating steps or additional tools. Moreover, multiple first adjusting screws control multiple first guide plates respectively, ensuring the independence and accuracy of the adjustment of each first guide plate. This allows each first guide plate to be adjusted to a suitable height according to actual needs, and precisely controls the opening and closing degree of the guide gap. In this way, manufactured sand of different conveying volumes and particle sizes can enter the subsequent processing stage in the most suitable state under the guidance of the first guide plate, greatly improving the effect of initial crushing, standardization, and agglomeration of manufactured sand, and laying a solid foundation for the efficient operation of the entire conveying and dispersing process.

[0008] The present invention is further configured such that: the first guide plate group includes a plurality of first guide plates arranged at intervals along a direction perpendicular to the conveying direction of the manufactured sand, the first guide plates being arranged at an inclination relative to the conveying direction of the manufactured sand, and the first guide plates being arranged at an inclination relative to at least one of the first guide plates.

[0009] By adopting the above technical solution, when manufactured sand is conveyed on a belt conveyor, these inclined first guide plates can change the flow direction and speed of the manufactured sand, so that the manufactured sand can be more evenly distributed during the conveying process. The inclined arrangement of the first guide plates relative to at least one side further increases the diversity and flexibility of guidance, which helps to avoid problems such as accumulation and agglomeration of manufactured sand during the conveying process, ensuring that the manufactured sand can be conveyed smoothly forward. Moreover, this multi-angle and diversified guidance method can better adapt to manufactured sand of different particle sizes and conveying volumes. Among them, for manufactured sand with larger particle sizes, the inclination angle and spacing of the first guide plates can be adjusted to allow it to pass smoothly through the guide gap. For manufactured sand with smaller particle sizes, its flow path can be controlled more precisely, improving the stability of the conveying.

[0010] The present invention is further configured such that: the lead screw pair includes a slide seat disposed on the belt conveyor, a mounting seat slidably connected to the slide seat, a transmission nut disposed on the mounting seat, and a transmission lead screw rotatably connected to the slide seat; the transmission lead screw passes through the mounting seat and is threadedly connected to the transmission nut; and the scattering wheel is rotatably mounted on the mounting seat.

[0011] By adopting the above technical solution, when the transmission screw rotates, it drives the mounting seat to slide on the slide block because it is threadedly connected to the transmission nut. This structure allows the position of the dispersing wheel to be adjusted according to actual needs. That is, during the conveying of manufactured sand, the position of the dispersing wheel can be flexibly changed according to different conveying volumes, the accumulation state of manufactured sand, etc., to achieve the best dispersing effect. In addition, the transmission method of the screw pair has high precision, which can accurately control the moving distance and position of the dispersing wheel, further improving the quality and efficiency of conveying and dispersing manufactured sand.

[0012] The present invention is further configured such that the lead screw pair also includes a gripping part disposed on the transmission lead screw.

[0013] By adopting the above technical solution, it is easier for users to grasp and apply force.

[0014] The present invention is further configured such that: the mounting base has a receiving cavity and a groove communicating with the receiving cavity; the dispersing wheel includes a slider slidably connected to the groove, a pair of compression springs sleeved on the transmission screw, a rotating shaft rotatably connected between the two sliders, a pair of baffles disposed on the rotating shaft, a plurality of arcuate ribs disposed between the pair of baffles and arranged in a circumferential direction, and a support rib disposed between the arcuate ribs and the rotating shaft; the pair of compression springs are respectively arranged on both sides of the slider, and their ends respectively abut against the slider and the inner wall of the receiving cavity.

[0015] By adopting the above technical solution, the slider can slide in the groove. With the elastic effect of the compression spring, the dispersing wheel has a certain buffering capacity during operation. When the manufactured sand impacts the dispersing wheel during the conveying process, the slider can slide within a small range in the groove. The compression spring will be compressed or stretched accordingly to absorb and disperse the impact force, preventing the dispersing wheel from being damaged by excessive impact force and extending the service life of the dispersing wheel. Meanwhile, this buffering capability also allows the dispersing wheel to better adapt to different states of manufactured sand. For example, when the manufactured sand has a high bulk density, the dispersing wheel can adjust its working state through the sliding of the slider and the deformation of the compression spring, thereby more effectively dispersing the manufactured sand. In addition, the rotating shaft is rotatably connected between two sliders, and multiple arc-shaped ribs are arranged along the circumference between a pair of baffles and connected to the rotating shaft through support ribs. This structural design allows the dispersing wheel to form a large dispersing range when it rotates. The arc-shaped ribs can more effectively cut into the manufactured sand pile and disperse the accumulated manufactured sand, while the support ribs enhance the connection strength between the arc-shaped ribs and the rotating shaft, ensuring the structural stability of the dispersing wheel when rotating at high speed. During the conveying of manufactured sand, the dispersing wheel can continuously and efficiently disperse the manufactured sand, further improving the quality and efficiency of the conveying and dispersing of manufactured sand, and ensuring that the manufactured sand can be processed in a more uniform state in subsequent production.

[0016] The present invention is further configured such that: a second mounting bracket is bridging the belt conveyor; the second screw assembly includes a plurality of second adjusting nuts disposed on the second mounting bracket and a second adjusting screw threadedly connected to the second adjusting nuts; and a plurality of second guide plates in the second guide plate assembly are respectively disposed at the bottom ends of these second adjusting screws. By adopting the above technical solution, when manufactured sand is conveyed on the belt conveyor, the distance between the second guide plate and the manufactured sand on the belt conveyor can be adjusted according to the different conditions such as the flow rate and particle size of the manufactured sand. The second adjusting screw is rotated and the threaded engagement between the second adjusting screw and the second adjusting nut is used to make the second adjusting screw move up and down in the second adjusting nut, thereby driving the second guide plate to move up and down. In this way, the distance between the second guide plate and the manufactured sand on the belt conveyor can be adjusted to achieve the best guiding effect.

[0017] The present invention is further configured such that: the second guide plate group includes at least two pairs of second guide plates arranged at intervals along the conveying direction of the manufactured sand, the second guide plates being arranged at an inclination relative to the conveying direction of the manufactured sand, and a gradually narrowing guide gap being formed between the two second guide plates in each pair.

[0018] By adopting the above technical solution, when the manufactured sand passes through the guide gap, it will gradually converge towards the center along the inclined direction of the guide plate, making the distribution of the manufactured sand more concentrated and orderly during the conveying process. This guiding effect can effectively avoid problems such as dispersion and accumulation of manufactured sand during the conveying process, ensuring that the manufactured sand can be conveyed stably and smoothly forward. At the same time, multiple pairs of second guide plates are arranged at intervals along the conveying direction of the manufactured sand, which can guide and converge the manufactured sand multiple times at different positions, thereby improving the conveying state of the manufactured sand more comprehensively and effectively, enhancing the working performance and efficiency of the entire manufactured sand conveying and dispersing device, and better meeting the needs of actual production.

[0019] In summary, the beneficial technical effects of this utility model are as follows: the manufactured sand conveyed by the belt conveyor is first initially crushed, regulated, and aggregated by the first guide plate group, and then effectively dispersed by the self-rotating dispersing wheel to separate any potentially clumped manufactured sand, thus preventing blockages during subsequent conveying. Finally, the dispersed manufactured sand is guided and regulated again by the second guide plate group, enabling the manufactured sand to continue to be conveyed more smoothly on the belt conveyor, ensuring the high efficiency and stability of the entire conveying process.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figure 1 This utility model discloses a manufactured sand conveying and dispersing device, comprising a belt conveyor 1. Along the conveying direction of the manufactured sand, a first set of guide plates 2, a self-rotating dispersing wheel 4, and a second set of guide plates 6 are arranged sequentially on the conveying surface of the belt conveyor 1. The first guide plates 2 are movably mounted on the belt conveyor 1 via first screw pairs 3, with a gradually narrowing guide gap between the two outermost first guide plates 2. The dispersing wheel 4 is movably mounted on the belt conveyor 1 at both ends via lead screw pairs 5. The second guide plates 6 are movably mounted on the belt conveyor 1 via second screw pairs 7, with a gradually narrowing guide gap between the two outermost second guide plates 6.

[0027] When conveying manufactured sand, the belt conveyor 1 first passes through the first guide plate group 2. Since a gradually narrowing guide gap is formed between the two outermost first guide plates 2, and the first guide plates 2 can be raised and lowered via the first screw pair 3, the height of the first guide plates 2 and the opening and closing degree of the guide gap can be adjusted according to the conveying volume and particle size of the manufactured sand, ensuring that the manufactured sand is guided in an orderly manner upon entry, initially crushing, standardizing, and agglomerating it. Next, the manufactured sand reaches the self-rotating dispersing wheel 4. The dispersing wheel 4 is vertically and vertically mounted on the belt conveyor 1 via screw pairs 5 at both ends, and its height can also be adjusted according to the actual situation of the manufactured sand. When the manufactured sand passes through the self-rotating dispersing wheel 4, the dispersing wheel 4 is conveyed... The manufactured sand is forced to rotate, which effectively breaks it up and separates any clumps, preventing blockages during subsequent transport. Finally, the manufactured sand passes through the second guide plate group 6, which is adjustable via the second screw assembly 7. A gradually narrowing guide gap is formed between the two outermost guide plates 6, which further guides and organizes the broken-up manufactured sand, allowing it to continue being transported more smoothly on the belt conveyor 1. This ensures the efficiency and stability of the entire transport process. Furthermore, this adjustable design allows the device to adapt to different working conditions and the characteristics of the manufactured sand, making it highly versatile and practical, better meeting the needs of actual production.

[0028] Reference Figure 2 A first mounting frame 11 is bridging the belt conveyor 1. The first screw assembly 3 includes a plurality of first adjusting nuts 31 mounted on the first mounting frame 11 and a first adjusting screw 32 threadedly connected to the first adjusting nuts 31. A plurality of first guide plates 2 in the first guide plate 2 group are respectively disposed at the bottom ends of these first adjusting screws 32. At the same time, the first guide plate 2 group includes a plurality of first guide plates 2 arranged at intervals along a direction perpendicular to the conveying direction of the manufactured sand. These first guide plates 2 are arranged at an incline relative to the conveying direction of the manufactured sand, and the first guide plates 2 are arranged at an incline relative to at least one side of the first guide plate 2.

[0029] Operators can easily drive the first adjusting screw 32 to rise and fall by rotating the first adjusting nut 31, thereby achieving precise adjustment of the height and tilt direction of the first guide plate 2. This structural design makes the adjustment process simple and direct, without complicated operating steps or additional tools. When manufactured sand is conveyed on the belt conveyor 1, these tilted first guide plates 2 can change the flow direction and speed of the manufactured sand, allowing the manufactured sand to be more evenly distributed during the conveying process. The tilted arrangement of the first guide plates 2 relative to at least one side further increases the diversity and flexibility of guidance, helping to avoid problems such as accumulation and agglomeration of manufactured sand during the conveying process, ensuring that the manufactured sand can be conveyed smoothly forward. Moreover, this multi-angle and diversified guidance method can better adapt to manufactured sand of different particle sizes and conveying volumes. Among them, for manufactured sand with larger particle sizes, the tilt angle and spacing of the first guide plates 2 can be adjusted to allow it to pass smoothly through the guide gap. For manufactured sand with smaller particle sizes, its flow path can be controlled more precisely, improving the stability of the conveying process.

[0030] Reference Figure 3 The lead screw assembly 5 includes a slide 51 mounted on the belt conveyor 1, a mounting base 52 slidably connected to the slide 51, a transmission nut 53 mounted on the mounting base 52, a transmission lead screw 54 rotatably connected to the slide 51, and a gripping part 55 mounted on the transmission lead screw 54. The transmission lead screw 54 passes through the mounting base 52 and is threadedly connected to the transmission nut 53. The rotatable wheel 4 is rotatably mounted on the mounting base 52. In addition, the mounting base 52 has a receiving cavity 521 and a groove 522 communicating with the receiving cavity 521. The dispersing wheel 4 includes a slider 41 slidably connected to the groove 522, a pair of compression springs 42 sleeved on the transmission screw 54, a rotating shaft 43 rotatably connected between the two sliders 41, a pair of baffles 44 set on the rotating shaft 43, a plurality of arc-shaped ribs 45 set between the pair of baffles 44 and arranged in the circumferential direction, and a support rib 46 set between the arc-shaped ribs 45 and the rotating shaft 43. The pair of compression springs 42 are respectively arranged on both sides of the slider 41, and their two ends respectively abut against the slider 41 and the inner wall of the receiving cavity 521.

[0031] When the drive screw 54 rotates, its threaded connection with the drive nut 53 causes the mounting base 52 to slide on the slide block 51. This structure allows the position of the dispersing wheel 4 to be adjusted according to actual needs. During the conveying of manufactured sand, the position of the dispersing wheel 4 can be flexibly changed based on different conveying volumes and the accumulation state of the manufactured sand to achieve the best dispersing effect. Furthermore, the screw pair's transmission method has high precision, enabling accurate control of the moving distance and position of the dispersing wheel 4, further improving the quality and efficiency of the manufactured sand conveying and dispersing. The slider 41 can slide within the groove 522. Combined with the elasticity of the compression spring 42, the dispersing wheel 4 has a certain buffering capacity during operation. When the manufactured sand impacts the dispersing wheel 4 during conveying, the slider 41 can slide within a small range within the groove 522, and the compression spring 42 will compress or stretch accordingly, absorbing and dispersing the impact force, preventing damage to the dispersing wheel 4 due to excessive impact, and extending the service life of the dispersing wheel 4. Meanwhile, this buffering capacity also allows the dispersing wheel 4 to better adapt to different states of manufactured sand. For example, when the density of manufactured sand is high, the dispersing wheel 4 can adjust its working state through the sliding of the slider 41 and the deformation of the compression spring 42, thereby more effectively dispersing the manufactured sand. In addition, the rotating shaft 43 is rotatably connected between the two sliders 41, and multiple arc-shaped ribs 45 are arranged along the circumference between a pair of baffles 44 and connected to the rotating shaft 43 through the support ribs 46. This structural design allows the dispersing wheel 4 to form a larger dispersing range when it rotates. The arc-shaped ribs 45 can more effectively cut into the manufactured sand pile and disperse the piled manufactured sand, while the support ribs 46 enhance the connection strength between the arc-shaped ribs 45 and the rotating shaft 43, ensuring the structural stability of the dispersing wheel 4 when it rotates at high speed. During the conveying of manufactured sand, the dispersing wheel 4 can continuously and efficiently disperse the manufactured sand, further improving the quality and efficiency of the conveying and dispersing of manufactured sand, and ensuring that the manufactured sand can be processed in a more uniform state in subsequent production.

[0032] Reference Figure 4 A second mounting bracket 12 is bridging the belt conveyor 1. The second screw assembly 7 includes multiple second adjusting nuts 71 mounted on the second mounting bracket 12 and second adjusting screws 72 threadedly connected to the second adjusting nuts 71. Multiple second guide plates 6 in the second guide plate group 6 are respectively disposed at the bottom ends of these second adjusting screws 72. Meanwhile, the second guide plate group 6 includes at least two pairs of second guide plates 6 arranged at intervals along the conveying direction of the manufactured sand. These second guide plates 6 are inclined relative to the conveying direction of the manufactured sand, and a gradually narrowing guide gap is formed between the two second guide plates 6 in each pair.

[0033] When manufactured sand is conveyed on belt conveyor 1, the distance between the second guide plate 6 and the manufactured sand on belt conveyor 1 can be adjusted according to the flow rate, particle size, and other factors of the manufactured sand. The second adjusting screw 72 moves up and down within the second adjusting nut 71 through its threaded engagement with the second adjusting nut 71, thereby moving the second guide plate 6 up and down. This adjusts the distance between the second guide plate 6 and the manufactured sand on belt conveyor 1 to achieve optimal guiding effect. As the manufactured sand passes through the guide gap, it gradually converges towards the center along the inclined direction of the guide plate, making the distribution of the manufactured sand more concentrated and orderly during conveying. This guiding effect effectively avoids problems such as dispersion and accumulation of the manufactured sand during conveying, ensuring stable and smooth forward conveying. Simultaneously, multiple pairs of second guide plates 6 are arranged at intervals along the conveying direction of the manufactured sand, allowing for multiple guidance and convergence of the manufactured sand at different positions. This more comprehensively and effectively improves the conveying state of the manufactured sand, enhances the working performance and efficiency of the entire manufactured sand conveying and dispersing device, and better meets the needs of actual production.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
