Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of coal chute equipment, and more specifically, to a circulating feeding vibrating chute. Background Art

[0002] A chute is one of the important transportation equipment in a coal preparation plant. It is mainly used for material transfer and transportation between production equipment, between production equipment and transportation equipment, and between transportation equipment. The design purpose of the chute is to enable materials to slide along a certain inclination angle, so as to achieve continuous transportation of materials.

[0003] Most of the existing chutes in coal preparation plants are simply inclined channels used to automatically transport materials from a high place to a low place. In actual use, coal block particles sliding / rolling in the channel are prone to local accumulation, resulting in uneven material distribution; at the same time, when materials slide / roll, they will inevitably collide with each other, generating dust. After long-term operation, especially in a humid environment, the dust is likely to adhere to the bottom of the chute, reducing the smoothness of material sliding / rolling. Therefore, it is necessary to improve and optimize the existing technology. Summary of the Invention

Each group of rod bodies includes several rod bodies, and the several rod bodies in the same group are spaced apart along the circumferential direction of the hollow shaft body. The holes are communicated with the inner cavity of the hollow shaft body, and the holes are disposed on the rod bodies.

[0011] For example, in the circulating feeding vibrating chute provided by at least one embodiment of the present disclosure, an air supply assembly for providing air flow is further included. The air supply assembly includes: An air pump is disposed on the main frame; There are two conduits, which are arranged on the connecting frame, with one end communicating with the air outlet of the air pump and the other end communicating with the inner cavity of the hollow shaft body.

[0023] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0024] As Figures 1 to 11 shown, it shows a circulating feeding vibrating chute in an embodiment of this disclosure. For example, as Figures 1 to 3As shown, the circulating material vibrating chute provided in this embodiment includes a base 1, a channel 2 is arranged above the base 1, and a vibration assembly 3 is arranged between the channel 2 and the base 1. The vibration assembly 3 is located at the bottom of the channel 2. The vibration assembly 3 adopts a vibration motor commonly used in the prior art. Four pillars are arranged on the base 1, and springs are fixed on the tops of the four pillars. The outer ends of the springs are fixedly connected to the bottom of the channel 2; the channel 2 is driven to vibrate in the vertical direction through the reciprocating motion of the vibration motor. A lever 4 is arranged in the inner cavity of the channel 2, and the rotation axis of the lever 4 is arranged at an angle with the width direction of the channel 2, so that when the lever 4 rotates, its end can form a composite motion trajectory in the length and width directions of the channel 2. The sliding drive assembly 5 includes a linear guide rail fixedly arranged at the top of the channel 2, and the linear guide rail extends along the width direction of the channel 2. A slider is arranged on the guide rail, and the slider is connected to one end of the lever 4 through a connecting seat. The rotation drive assembly 6 includes a rotation driver 61 mounted on the connection seat. The rotation driver 61 is preferably a motor that can provide rotation drive in the prior art. The output shaft of the rotation driver 61 is connected to one end of the lever 4 through the rotation transmission assembly 7. When the rotation driver 61 is working, it drives the lever 4 to rotate around its axis. When the sliding drive assembly 5 drives the lever 4 to slide along the width direction of the channel 2, and the rotation drive assembly 6 drives the lever 4 to rotate, the lever 4 forms a spiral material-moving motion in the channel 2, thereby achieving homogenization of the material. A distance sensor is arranged above the channel 2, and the distance sensor can effectively identify the thickness of the material in the inner cavity of the channel 2 to avoid excessive accumulation of materials.

[0025] The vibration component 3 drives the groove 2 to vibrate, so that the material in the groove 2 can be kept in a loose state during the conveying process, reduce the local blockage caused by the accumulation of materials due to gravity, and improve the fluidity of the materials. The rotation axis of the lever 4 is set at an angle to the sliding direction. In this example, the rotation axis of the lever 4 is preferably parallel to the conveying direction of the material in the groove 2, and the rotation axis of the lever 4 is set at a right angle to the sliding direction; so that the lever 4 slides along the width direction of the groove 2 while rotating, and the movement trajectory of its end in the groove 2 covers the entire cross-section of the groove 2, which can effectively disperse the accumulated materials to the surroundings, avoid the concentrated accumulation of materials in a certain area in the groove 2, and achieve uniform material distribution. The cooperation of the sliding drive component 5 and the rotating drive component 6 enables the lever 4 to perform compound movements in the groove 2, which improves the efficiency and effect of material homogenization compared with the traditional single vibration or material shifting method. The coordinated work of the vibration component 3 and the lever 4 not only utilizes vibration to loosen the material initially, but also further homogenizes it through the movement of the lever 4. The dual action ensures that the material in the chute 2 is always in a uniform conveying state, which solves the problem of uneven material distribution caused by local accumulation of materials in the chute in the prior art, improves the stability and reliability of material transportation, and reduces the material deposited on the chute 2.

[0026] In some examples, the lever 4 is further improved. For example, as Figures 1 to 5 shown, based on the above-mentioned circulating feeding vibrating chute, in this embodiment, the lever 4 is further improved. The lever 4 is designed as a hollow structure, and its outer end is provided with holes 41 for air flow ejection. The lever 4 is connected to the air supply assembly 8. The air supply assembly 8 uses an air pump 81, and the air pump 81 is connected to the hollow inner cavity of the lever 4 through a conduit 82. When the air pump 81 works, the gas enters the hollow inner cavity of the lever 4 through the conduit 82 and then ejects from the holes 41 at the outer end. When the material conveying stops, the chute 2 can be purged by the rotation of the lever 4 and the output air flow, which is beneficial to improving the cleaning effect. When the material is being conveyed, the air flow output by the lever 4 can also blow away the dust accumulated at the bottom of the chute 2 to prevent the dust from piling up and affecting the material conveying.

[0027] The hollow structure of the lever 4 and the air flow ejected from the holes 41 at the outer end can effectively blow the dust in the inner cavity of the chute 2. During the material conveying process, the collision between materials will generate dust, and these dusts are easy to accumulate in the chute 2, especially in the case of high humidity, the dust is easy to adhere to the bottom of the chute, reducing the smoothness of the material sliding / rolling. The blowing of the air flow can keep the dust in a suspended state, reducing the adhesion and accumulation of the dust at the bottom of the chute 2. At the same time, combined with the vibration assembly 3 to keep the material in a loose state and the material leveling effect of the lever 4, the blowing of the air flow further prevents the local caking phenomenon formed after the dust is mixed with the material, which helps the material to be conveyed more smoothly in the chute 2. In this way, the vibration assembly 3, the material feeding of the lever 4 and the blowing of the air flow cooperate with each other, solving the problems existing in the chute in the prior art from multiple aspects, not only realizing the uniform distribution of the material, but also improving the smoothness of the material conveying, and further enhancing the stability and reliability of the material conveying.

[0028] In some examples, when the number of levers 4 is two, the sliding drive assembly 5 is refined. For example, as Figures 1 to 7As shown in the figure, on the basis of the above-mentioned circulating feeding vibrating chute, in this embodiment, the sliding drive assembly 5 is refined for the case where the number of the dial rods 4 is two. The main frame 51 of the sliding drive assembly 5 is slidably arranged on the side wall of the chute 2 and is located inside the inner cavity of the chute 2. The main frame 51 has a groove 511, and the opening of the groove 511 points to the conveying direction of the material. The double-shaft drive 52 is arranged in the groove 511. The two ends of the double-shaft drive 52 are respectively provided with a first lead screw 53. The double-shaft drive 52 can be a motor that can provide rotational drive in the prior art. The first slider 54 is slidably arranged in the groove 511 and is threadedly connected with the first lead screw 53. One end of the connecting frame 55 is arranged on the first slider 54, and the other end extends to the outside opposite to the bottom surface of the groove 511 and is respectively rotatably connected with the two dial rods 4. When the double-shaft drive 52 works, it drives the first lead screws 53 at both ends to rotate. Since the first slider 54 is threadedly connected with the first lead screw 53, the rotation of the first lead screw 53 will drive the first slider 54 to slide along the width direction of the chute 2, and then drive the two dial rods 4 to slide synchronously along the width direction of the chute 2 through the connecting frame 55.

[0029] The number of the dial rods 4 is set to two, which increases the feeding range and effect. The sliding drive assembly 5 composed of the double-shaft drive 52, the first lead screw 53, the first slider 54 and the connecting frame 55 can accurately control the sliding of the two dial rods 4 along the width direction of the chute 2. The double-shaft drive 52 can drive the two first lead screws 53 to rotate simultaneously, ensuring the synchronism of the sliding of the two dial rods 4 and making the movement of the two dial rods 4 in the chute 2 more coordinated. Compared with a single dial rod 4, the two dial rods 4 can more comprehensively cover the width direction of the chute 2 during the sliding process, and can more effectively disperse the accumulated material to the surrounding, further improving the material homogenization effect. Moreover, the sliding drive assembly 5 with this structure has high stability, can withstand the acting force generated by the dial rod 4 during the feeding process, and ensures the reliable operation of the entire circulating feeding vibrating chute. At the same time, the orientation of the opening can effectively prevent the material from falling into the groove 511 during the conveying process, ensuring the stability of the equipment operation; combined with the vibration effect of the vibration assembly 3, the rotation of the dial rod 4 and the effect of the airflow ejected from the holes 41, the problems of local material accumulation and uneven cloth distribution are solved from multiple dimensions, and at the same time, the smoothness and stability of material conveying are improved.

[0030] In some examples, the rotational drive assembly 6 is refined. For example, as Figures 1 to 6As shown in the figure, based on the above-mentioned cyclic feeding vibrating chute, in this embodiment, the rotation driving assembly 6 is refined. The rotation driver 61 of the rotation driving assembly 6 is arranged on the connecting frame 55, and the transmission sleeve 62 is also arranged on the connecting frame 55. The output shaft of the rotation driver 61 extends into the transmission chamber 63 of the transmission sleeve 62, and one end of the dial rod 4 extends into the transmission chamber 63 and is rotatably connected to the transmission sleeve 62. A rotation transmission assembly 7 is arranged in the transmission chamber 63, and the rotation transmission assembly 7 is used to transmit the power output by the rotation driver 61 to the dial rod 4 to drive the dial rod 4 to rotate. When the rotation driver 61 works, its output shaft drives the dial rod 4 to rotate around its own axis through the rotation transmission assembly 7. At the same time, the sliding driving assembly 5 drives the dial rod 4 to slide in the width direction of the chute 2, so that the dial rod 4 performs a feeding movement on the material in the chute 2.

[0031] The rotation driving assembly 6 transmits the power of the rotation driver 61 to the dial rod 4 through the rotation transmission assembly 7, realizing the stable rotation of the dial rod 4. The setting of the transmission sleeve 62 provides support and guidance for the rotation of the dial rod 4, ensuring the stability and accuracy of the rotation of the dial rod 4. The cooperation of the rotation driver 61, the transmission sleeve 62 and the rotation transmission assembly 7 enables the dial rod 4 to rotate at a suitable speed, which is coordinated with the sliding movement of the dial rod 4 in the width direction of the chute 2. It can more comprehensively perform feeding and homogenization treatment on the material in the chute 2. Compared with a single vibration or feeding method, the efficiency and effect of material homogenization are greatly improved. Combining the functions of the vibration assembly 3 to loosen the material, the air flow blown out from the holes 41 in the hollow structure of the dial rod 4 to blow the dust, and the sliding driving assembly 5 driving the dial rod 4 to slide, etc., the problems of local accumulation and uneven distribution of the material are solved synergistically from multiple aspects, further improving the smoothness and stability of material transportation, and ensuring the efficient operation of the entire cyclic feeding vibrating chute.

[0032] In some examples, the rotation transmission assembly 7 is described in detail. For example, as Figures 1 to 8As shown in the figure, based on the above-mentioned circulating feeding vibrating chute, the rotating transmission assembly 7 in this embodiment will be described in detail. The rotating transmission assembly 7 is arranged in the transmission chamber 63 of the transmission sleeve 62. Among them, the first transmission gear 71 is arranged on the output shaft of the rotating driver 61, and the transmission gear ring 72 is arranged on the dial rod 4 and located in the transmission chamber 63. The transmission shaft 73 is rotatably arranged in the transmission chamber 63, and two second transmission gears 74 are arranged on the transmission shaft 73 at intervals. One of the second transmission gears 74 is meshed with the first transmission gear 71, and the other second transmission gear 74 is meshed with the transmission gear ring 72. When the rotating driver 61 works, its output shaft drives the first transmission gear 71 to rotate. The first transmission gear 71 drives the transmission shaft 73 to rotate through the second transmission gear 74 meshed with it. The transmission shaft 73 then drives the transmission gear ring 72 to rotate through the other second transmission gear 74, so as to make the dial rod 4 rotate around its own axis. The sliding drive assembly 5 drives the dial rod 4 to slide along the width direction of the chute 2.

[0033] The rotating transmission assembly 7 transmits the power of the rotating driver 61 to the dial rod 4 stably and efficiently through the meshing transmission of multiple gears. The cooperation of the first transmission gear 71, the second transmission gears 74, the transmission shaft 73 and the transmission gear ring 72 ensures that the dial rod 4 rotates at an appropriate speed. This gear transmission method has high transmission efficiency and stability, can withstand large torques, and ensures the reliability of the dial rod 4 during the feeding process. Combined with the sliding movement of the dial rod 4, it makes the spiral feeding movement formed by the dial rod 4 in the chute 2 more stable and effective. Compared with other transmission methods, gear transmission can better adapt to complex working environments and frequent start-stop operations. Combined with the vibration assembly 3 to loosen the material, the air flow blown out from the holes 41 in the hollow structure of the dial rod 4 to blow the dust, and the sliding drive assembly 5 driving the dial rod 4 to slide and other functions, it further improves the effect of material homogenization, solves the problems of local material accumulation and uneven cloth distribution, improves the smoothness and stability of material transportation, and ensures the stable operation of the entire circulating feeding vibrating chute.

[0034] In some examples, the structure of the dial rod 4 is refined. For example, as Figures 1 to 9As shown in the figure, on the basis of the above-mentioned circulating feeding vibrating chute, the structure of the dial rod 4 is refined in this embodiment. The dial rod 4 includes a hollow shaft body 42 and a rod body 43. One end of the hollow shaft body 42 extends into the transmission chamber 63 of the transmission sleeve 62 and is rotatably connected to the transmission sleeve 62. A plurality of groups of rod bodies 43 are distributed at intervals along the extending direction of the hollow shaft body 42, and each group of rod bodies 43 includes a plurality of rod bodies 43 distributed at intervals along the circumferential direction of the hollow shaft body 42. The outer end of the hollow shaft body 42 is provided with holes 41 for air flow to eject, and the holes 41 are communicated with the inner cavity of the hollow shaft body 42. The conduit 82 of the air supply assembly 8 is communicated with the inner cavity of the hollow shaft body 42. When the air pump 81 works, the gas enters the inner cavity of the hollow shaft body 42 through the conduit 82 and then ejects from the holes 41. When the rotation driver 61 drives the hollow shaft body 42 to rotate through the rotation transmission assembly 7, the rod body 43 rotates accordingly. At the same time, the sliding drive assembly 5 drives the dial rod 4 to slide along the width direction of the chute 2, so that the rod body 43 forms a spiral feeding motion in the chute 2.

[0035] The dial rod 4 adopts the structural cooperation of the hollow shaft body 42 and the rod body 43, and the distribution mode of the rod body 43 increases the feeding area and range. During the rotation and sliding of the dial rod 4, multiple groups of rod bodies 43 can contact the material more comprehensively, disperse the accumulated material to the surrounding, and improve the effect of material homogenization. The design of the hollow shaft body 42 enables the air flow to eject from the holes 41 through its inner cavity. While the dial rod 4 is feeding, the ejected air flow can blow the dust in the chute 2, reduce the dust accumulation, and contribute to the smooth conveying of the material. The rotation transmission assembly 7 drives the hollow shaft body 42 to rotate, combined with the sliding action of the sliding drive assembly 5, so that the rod body 43 forms a spiral feeding motion. This compound motion mode can better adapt to the distribution of the material in the chute 2 and further improve the effects of material homogenization and conveying. Working in coordination with other components such as the vibration assembly 3 and the air supply assembly 8, it solves the problems of local material accumulation and uneven cloth distribution from multiple aspects and ensures the stable conveying of the material in the chute 2.

[0036] In some examples, the air supply assembly 8 is described. For example, as Figures 1 to 5 shown, on the basis of the above-mentioned circulating feeding vibrating chute, the air supply assembly 8 is described in this embodiment. The air supply assembly 8 includes an air pump 81 and a conduit 82. The air pump 81 is arranged on the main frame 51, and the number of the conduits 82 is two. One ends of the two conduits 82 are both communicated with the air outlet of the air pump 81, and the other ends are respectively communicated with the inner cavities of the hollow shaft bodies 42 of the two dial rods 4. When the air pump 81 works, the generated air flow enters the inner cavity of the hollow shaft body 42 through the conduit 82 and then ejects from the holes 41 at the outer end of the hollow shaft body 42. During the process that the rotation driver 61 drives the dial rod 4 to rotate through the rotation transmission assembly 7 and the sliding drive assembly 5 drives the dial rod 4 to slide along the width direction of the chute 2, the holes 41 continuously eject the air flow, which acts on the dust in the inner cavity of the chute 2.

[0037] The air supply assembly 8 supplies air flow to the lever 4 through the air pump 81 and the conduit 82, so that the air can be ejected from the holes 41 in the hollow shaft body 42 of the lever 4. The ejection of the air flow can effectively blow the dust in the inner cavity of the chute 2, avoid the accumulation and adhesion of the dust in the chute 2, and improve the smoothness of the material sliding. The air pump 81 is arranged on the main frame 51 and moves together with the main frame 51, ensuring the stability and continuity of the air supply. At the same time, the structure of the whole device is made more compact. The two conduits 82 supply air to the two levers 4 respectively, ensuring that there is enough air flow ejected from the holes 41 of each lever 4, enhancing the effect of blowing the dust. At the same time, one end of the conduit 82 close to the air pump 81 is a flexible tube, and the other end is a rigid tube, which cooperates with the sliding of the lever 4. Combining with the vibration assembly 3 to loosen the material, the feeding of the rod body 43 of the lever 4, and the compound movement of rotation and sliding, the air supply assembly 8 further improves the effect of material homogenization and transportation from the perspective of solving the dust problem, collaboratively solves the problems of local accumulation of materials and uneven distribution of cloth, and ensures the stable operation of the circulating feeding vibration chute.

[0038] In some examples, the structure of the air supply assembly 8 is further refined. For example, as Figures 1 to 10 shown, on the basis of the above-mentioned circulating feeding vibration chute, the structure of the air supply assembly 8 is further refined in this embodiment. An inner shaft 83 is arranged in the inner cavity of the hollow shaft body 42. The inner shaft 83 is of a hollow structure and has exhaust holes 84. A plurality of partition plates 85 are distributed at intervals along the circumferential direction of the inner shaft 83, are arranged on the outer surface of the inner shaft 83 and are in contact with the inner cavity surface of the hollow shaft body 42. An air cavity 86 is formed between any two adjacent partition plates 85, the outer surface of the inner shaft 83, and the inner cavity surface of the hollow shaft body 42. One of the air cavities 86 is communicated with the exhaust holes 84. After the hollow shaft body 42 rotates, one of the rod bodies 43 in each group of rod bodies 43 can be communicated with an air cavity 86. The conduit 82 of the air supply assembly 8 is communicated with the inner cavity of the hollow shaft body 42. When the air pump 81 works, the gas enters the inner cavity of the hollow shaft body 42, and part of the gas enters the inner shaft 83 through the air cavity 86 communicated with the exhaust holes 84, and then is ejected through the rod body 43 communicated with the air cavity 86.

[0039] The structure of the inner shaft 83, the partition plate 85 and the air cavity 86 is arranged inside the lever 4, making the flow of the air flow in the lever 4 more reasonable and orderly. In this example, the opening direction of the exhaust hole 84 points to the material in the chute 2. As the hollow shaft body 42 rotates, the rod bodies 43 at different positions on the hollow shaft body 42 communicate with the air cavity 86 where the exhaust hole 84 is located. Through the cooperation of this structure, the air flow output by the exhaust hole 84 is only output towards the bottom of the chute 2, improving the effectiveness of the air flow; in this example, the number of the partition plates 85 and the air cavities 86 is preferably four each. Looking along the axis line of the inner shaft 83, there are four air cavities 86, namely the upper, lower, left and right air cavities 86 respectively, and the air cavity 86 where the exhaust hole 84 is located is at the lower part; this ensures the effectiveness of the air flow; at the same time, the adjacent two groups of rod bodies 43 are arranged in a staggered manner, ensuring that there is a connection between the lever 4 and the lower air cavity 86 during operation, ensuring the continuity of the operation; when the lever 4 communicates with the upper, left and right air cavities 86, the lever 4 does not discharge air flow outwards at this time. Combining the vibration assembly 3 to loosen the material, the material-pushing movement of the lever 4 and the overall air supply effect of the air supply assembly 8, this structure further optimizes the treatment of dust, reduces the influence of dust on the material conveying, improves the material homogenization and conveying effect, and ensures the stable operation of the circulating material-pushing vibrating chute.

[0040] In some examples, the structure of the air supply assembly 8 is further improved. For example, as Figures 1 to 10 shown, on the basis of the above-mentioned circulating material-pushing vibrating chute, the structure of the air supply assembly 8 is further improved in this embodiment. The air supply assembly 8 further includes a head 87 and an air extraction pipe 88. The head 87 is arranged on the inner shaft 83 and is located in the transmission chamber 63. The head 87 communicates with another one of the air cavities 86. One end of the air extraction pipe 88 extends into the transmission chamber 63 and communicates with another one of the air cavities 86 by means of the head 87. When the air pump 81 works to make the gas enter the inner cavity of the hollow shaft body 42 through the conduit 82, while part of the gas is ejected from the rod body 43 through the air cavity 86 communicated with the exhaust hole 84, the air extraction pipe 88 starts to extract the gas in another one of the air cavities 86. When the rotation driver 61 drives the hollow shaft body 42 to rotate and the sliding drive assembly 5 drives the lever 4 to slide along the width direction of the chute 2, the lever 4 continuously performs the material-pushing operation, and the ejection and extraction of the air flow are carried out simultaneously.

[0041] The arrangement of the end head 87 and the air extraction pipe 88 forms an air flow circulation within the shift lever 4. The air pump 81 outputs air flow through the lower air chamber 86 and the corresponding shift lever 4. The output air flow blows the dust upwards and disperses it. At this time, the air extraction pipe 88 sucks the gas in the upper air chamber 86. The shift lever 4 communicating with the upper air chamber 86 will suck the dispersed dust and gas, and then transport them to a filtering device communicated with the air extraction pipe 88, such as a bag filter in the prior art, thereby intercepting the dust and completing the collection of the dust. It can also prevent the dust from accumulating in the air chamber 86, ensure the smoothness of the air chamber 86, and thus ensure the normal flow of the air flow within the shift lever 4. The air chambers 86 at the left and right positions are used for transitional purposes to prevent the air flow output by the air pump 81 from directly entering the air extraction pipe 88, reducing the function and effect of the air supply assembly 8. The air flow circulation enables the dust not to stay in the shift lever 4 and specific areas of the channel 2 for a long time. Combining with the air flow blown out by the rod body 43 to blow the dust in the channel 2, it strengthens the treatment of the dust from both inside and outside. On the one hand, the air flow blown out by the rod body 43 raises the dust in the channel 2; on the other hand, the air extraction pipe 88 extracts the gas with dust from the air chamber 86, effectively reducing the dust content in the channel 2. This air flow circulation, together with the vibration assembly 3 that loosens the material, the material shifting movement of the shift lever 4, etc., further improves the effect of material homogenization, improves the smoothness of material transportation, and ensures the stable operation of the circulating material shifting vibration chute.

[0042] In some examples, the sliding drive assembly 5 is further supplemented. For example, as Figures 1 to 2 and Figure 11 shown, on the basis of the above-mentioned circulating material shifting vibration chute, in this embodiment, the sliding drive assembly 5 is further supplemented. In addition to the main frame 51, the dual-axis driver 52, the first lead screw 53, the first slider 54, and the connecting frame 55, the sliding drive assembly 5 further includes a lead screw motor 56 and a slide seat 58. The lead screw motor 56 is arranged on the side wall of the channel 2, and a second lead screw 57 is arranged on its output shaft. The slide seat 58 is arranged on the main frame 51 and is threadedly connected to the second lead screw 57. When the lead screw motor 56 works, its output shaft drives the second lead screw 57 to rotate. Since the slide seat 58 is threadedly connected to the second lead screw 57, the rotation of the second lead screw 57 will drive the slide seat 58 and the main frame 51 to slide synchronously along the extending direction of the channel 2. When the dual-axis driver 52 works, it drives the first lead screws 53 at both ends to rotate, causing the first sliders 54 to slide along the groove 511 of the main frame 51, and then driving the shift lever 4 to slide along the width direction of the channel 2 through the connecting frame 55. Therefore, under the combined action of the lead screw motor 56 and the dual-axis driver 52, the shift lever 4 can move more flexibly along the width direction within the channel 2. At the same time, the rotation drive assembly 6 drives the shift lever 4 to rotate, causing the shift lever 4 to form a complex spiral material shifting movement within the channel 2.

[0043] The addition of the lead screw motor 56 and the slide block 58 enhances the driving ability and flexibility of the sliding drive assembly 5. The lead screw motor 56 drives the main frame 51 to slide along the extension direction of the channel 2 through the second lead screw 57, which cooperates with the sliding of the lever 4 on the main frame 51 driven by the double-axis drive 52, enabling the lever 4 to have a wider movement range and more diverse movement modes in the width direction of the channel 2. The cooperation of such multiple drive sources can more accurately control the position and movement trajectory of the lever 4 according to the actual stacking situation and conveying requirements of the material, improving the effect of material pushing. Combined with the functions of the vibration assembly 3 to loosen the material, the rotation of the lever 4, and the ejection of air flow through the hollow structure to blow the dust, etc., the homogenization process of the material is further optimized, and the problems of local material accumulation and uneven cloth distribution are more effectively solved. The multi-driven sliding drive assembly 5 improves the adaptability of the entire circulating material pushing and vibrating chute to different working conditions, ensuring the stability and reliability of material conveying.
