[0047] In order to better explain the utility model, so as to facilitate understanding, the utility model is described in detail below by specific embodiments, combined with the drawings.

[0048] Referring to Figure 1 and Figure 2 In the process of coal caving mining, when the tail beam of the hydraulic support is retracted, the coal, coal dust and gangue will jump out of the back chute of the scraper and accumulate in large quantities, which will affect the forward movement of the back scraper, and manual removal has safety hazards. The shovel plate mechanism provided by the technical scheme aims to solve the problem of material accumulation, avoid the safety risks caused by manual removal, and ensure the normal forward movement of the scraper.

[0049] In order to solve at least one of the technical problems existing in the prior art or related art, the utility model provides a shovel plate mechanism including a linkage frame, a shovel plate assembly, a first driving unit and a second driving unit. The first driving unit drives the shovel plate assembly to rotate, adjusts the angle of the driving shovel plate relative to the accumulated material, and the second driving unit drives the linkage frame to rotate, cooperates with the first driving unit, so that it can effectively shovel the material. Through the cooperation of the first driving unit and the second driving unit, the shovel plate assembly is controlled to shovel the supporting material into the back chute of the scraper, thereby avoiding the influence of material accumulation on the forward movement of the back scraper, and ensuring the normal operation of coal mining.

[0050] The shovel plate mechanism and the hydraulic support according to some embodiments provided by the utility model are described below with reference to the drawings.

[0051] Referring to Figure 2 and Figure 3The utility model provides a kind of shovel plate mechanism 500, it is applied to hydraulic support, and hydraulic support includes base 100, top beam 200 and tail beam 400, top beam 200 is set on the top of base 100, tail beam 400 is rotatably installed in one side of top beam 200, shovel plate mechanism 500 includes: connecting rod frame 510, is hingedly installed on base 100;Shovel plate assembly 520 is set on the side of connecting rod frame 510 away from base 100, and shovel plate assembly 520 is hinged with connecting rod frame 510;First drive unit 530 is set between base 100 and shovel plate assembly 520, for driving shovel plate assembly 520 to rotate in the direction of approaching or away from tail beam 400;Second drive unit 540 is set between base 100 and connecting rod frame 510, for driving connecting rod frame 510 to rotate in the direction of approaching or away from tail beam 400.

[0052] The shovel plate mechanism 500 provided by the embodiment is applied to hydraulic support, and the shovel plate mechanism 500 includes connecting rod frame 510, shovel plate assembly 520, first drive unit 530 and second drive unit 540, wherein the connecting rod frame 510 is hingedly installed on the base 100, and the connecting rod frame 510 can rotate around the hinged point of the connecting rod frame 510 and the base 100;The shovel plate assembly 520 is arranged on the side of the connecting rod frame 510 away from the base 100, and is hinged with the connecting rod frame 510, and the shovel plate assembly 520 can rotate around the hinged point of the shovel plate assembly 520 and the connecting rod frame 510;The first drive unit 530 is arranged between the base 100 and the shovel plate assembly 520, and the second drive unit 540 is arranged between the base 100 and the connecting rod frame 510;The rotation axes of the connecting rod frame 510 and the base 100, the rotation axes of the shovel plate assembly 520 and the connecting rod frame 510, and the rotation axes of the tail beam 400 and the top beam 200 are all parallel to each other, so that the connecting rod frame 510, the shovel plate assembly 520 and the tail beam 400 can operate in the same space, the work of shoveling coal can be realized, and the functions of smoothly discharging coal and cleaning materials can be realized.

[0053] As can be known from the above, the connecting rod frame 510 serves as a support and transmission component of the shovel plate assembly 520, provides a mounting base for the shovel plate assembly 520, and cooperates with the second drive unit 540 to realize the function of controlling the position of the shovel plate assembly 520;The shovel plate assembly 520 is a working component for directly shoveling accumulated blocky coal, coal dust and gangue, and can effectively shovel and clean the accumulated materials by rotating and adjusting the position, so that the materials around the rear chute 600 of the scraper do not affect the forward movement of the scraper.

[0054] The first driving unit 530 is used to drive the shovel plate assembly 520 to rotate towards the tail beam 400 or away from the tail beam 400. Through the action of the first driving unit 530, the angle of the shovel plate assembly 520 can be adjusted, so that the shovel plate assembly 520 can better adapt to different material accumulation conditions and working requirements, to achieve the best shoveling effect. The second driving unit 540 is used to drive the connecting rod frame 510 to rotate towards the tail beam 400 or away from the tail beam 400. Through the action of the second driving unit 540, the position of the connecting rod frame 510 relative to the base 100 can be adjusted, and at the same time, the shovel plate assembly 520 is controlled to move together with the connecting rod frame 510, further adjusting the position of the shovel plate assembly 520, to achieve the effect of cleaning the material accumulation.

[0055] For example, the rear chute 600 of the scraper is arranged below the tail beam 400. When the hydraulic support retracts the tail beam 400 at the rear end and the plug plate mechanism releases coal, a large amount of small blocky coal, coal dust and gangue will bounce out of the plug plate and the rear chute 600 of the scraper, causing a large accumulation and affecting the forward movement of the rear scraper. At this time, the material bounced out of the rear chute 600 of the scraper can be shoveled by the shovel plate mechanism 500 and sent into the rear chute 600 of the scraper. During cleaning, the first driving unit 530 and the second driving unit 540 work together. The first driving unit 530 drives the shovel plate assembly 520 to rotate, adjusts the angle of the driving shovel plate relative to the accumulated material, and the second driving unit 540 drives the connecting rod frame 510 to rotate, cooperates with the first driving unit 530, so that it can effectively shovel the material. Through the cooperation of the first driving unit 530 and the second driving unit 540, the shovel plate assembly 520 is controlled to support the material and transfer it into the rear chute 600 of the scraper, thereby avoiding the accumulation of material affecting the forward movement of the rear scraper and ensuring the normal operation of coal mining.

[0056] Referring to Figure 2 and Figure 3 In some examples, the first driving unit 530 is arranged above the connecting rod frame 510, and the second driving unit 540 is arranged below the connecting rod frame 510.

[0057] In this technical solution, the first driving unit 530 drives the shovel plate assembly 520 to rotate towards the tail beam 400 or away from the tail beam 400. When the first driving unit 530 acts, it can directly and effectively drive the shovel plate assembly 520 to rotate around the rotation axis of the connecting rod frame 510, so that the shovel plate assembly 520 can quickly adjust to the appropriate working angle to adapt to different material accumulation conditions and shoveling requirements. The second driving unit 540 drives the connecting rod frame 510 to rotate towards the tail beam 400 or away from the tail beam 400. When the second driving unit 540 acts, it can directly drive the connecting rod frame 510 to rotate around the rotation axis of the base 100, further adjusting the angle and position of the shovel plate assembly 520 to realize different actions of the shovel plate assembly 520.

[0058] The first driving unit 530 and the second driving unit 540 are arranged above and below the connecting rod frame 510 respectively, and both the first driving unit 530 and the second driving unit 540 have relatively open spaces, so that they do not interfere with each other when working, thereby stabilizing the operation of the shovel plate mechanism 500.

[0059] Further, the first driving unit 530 and the second driving unit 540 are arranged above and below the connecting rod frame 510 respectively, so that during daily maintenance, repair or replacement of parts, the workers do not need to disassemble complicatedly, and can more conveniently check, debug and maintain the first driving unit 530 and the second driving unit 540, thereby reducing the maintenance cost and difficulty and improving the maintainability of the equipment.

[0060] Referring to Figure 2 and Figure 3 In some examples, the second driving unit 540 is at least two, and the at least two second driving units 540 are oppositely arranged between the base 100 and the connecting rod frame 510; the second driving unit 540 is hingedly installed on the base 100, and the output end of the second driving unit 540 is hingedly connected with the connecting rod frame 510.

[0061] In the technical scheme, when the connecting rod frame 510 is driven to rotate to adjust the position of the shovel plate assembly 520, since the second driving unit 540 is arranged below the connecting rod frame 510, it not only bears the function of driving the connecting rod frame 510 to rotate towards the direction of approaching or moving away from the tail beam 400, but also plays a supporting role, so that a single second driving unit 540 cannot provide sufficient stable and balanced driving force; multiple second driving units 540 work simultaneously, can disperse the driving force to different positions of the connecting rod frame 510, so that the connecting rod frame 510 is more evenly stressed during rotation, avoiding the problem that the connecting rod frame 510 rotates not smoothly due to uneven stress, thereby ensuring that the shovel plate mechanism 500 can stably and reliably operate.

[0062] Further, when the shovel plate assembly 520 supports the material, the gravity of the material is transmitted to the connecting rod frame 510, the connecting rod frame 510 is supported by the second driving unit 540, and the connecting rod frame 510 and the shovel plate assembly 520 can be subjected to a relatively large resistance, multiple second driving units 540 work together to provide greater driving capacity, so as to ensure that the connecting rod frame 510 can smoothly rotate towards the direction of approaching or moving away from the tail beam 400, even in the case of encountering a relatively large resistance, the shovel plate mechanism 500 can also work normally, thereby improving the working efficiency and adaptability of the equipment.

[0063] Further, the relative arrangement of the at least two second driving units 540 helps to improve the stability of the entire shovel plate mechanism 500. When the second driving units 540 drive the connecting rod frame 510 to rotate, the at least two second driving units 540 can cooperate with each other to resist external interference and resistance, reduce the shaking and vibration of the equipment, make the shovel plate mechanism 500 more stable during operation, and reduce the probability of damage and failure of parts caused by vibration.

[0064] Referring to Figure 2 and Figure 3 In some examples, the shovel plate mechanism 500 further comprises: a first connecting rod 550, one end of which is fixedly installed on the shovel plate assembly 520; a second connecting rod 560, one end of which is hingedly installed on the connecting rod frame 510; and a rotating shaft 570, the other end of the first connecting rod 550 being rotatably installed on the rotating shaft 570, and the other end of the second connecting rod 560 being rotatably installed on the rotating shaft 570; wherein the first driving unit 530 is hingedly installed on the base 100, and the output end of the first driving unit 530 is rotatably installed on the rotating shaft 570.

[0065] In this technical solution, the shovel plate mechanism 500 further comprises the first connecting rod 550, the second connecting rod 560, and the rotating shaft 570. One end of the first connecting rod 550 is fixedly installed on the shovel plate assembly 520, so that the first connecting rod 550 and the shovel plate assembly 520 can move synchronously. When the first connecting rod 550 moves, it can directly drive the shovel plate assembly 520 to move correspondingly. One end of the second connecting rod 560 is hingedly installed on the connecting rod frame 510. The second connecting rod 560 and the first connecting rod 550 are rotatably installed on the rotating shaft 570. The rotating shaft 570 is the connecting pivot of the first connecting rod 550 and the second connecting rod 560, and can transmit the movement of the two connecting rods. The rotating shaft 570 receives the driving force of the first driving unit 530 and transmits the driving force to the shovel plate assembly 520 through the first connecting rod 550, so as to realize the rotation of the shovel plate assembly 520.

[0066] The first unit is hingedly installed on the base 100, and the output end of the first driving unit 530 is rotatably installed on the rotating shaft 570. The hinged installation on the base 100 enables the first driving unit 530 to rotate. The first driving unit 530, as a power source, drives the rotating shaft 570 to move through the output end. The rotating shaft 570 drives the first connecting rod 550 and the second connecting rod 560 to move under the drive of the first driving unit 530, thereby realizing the rotation of the shovel plate assembly 520 towards or away from the tail beam 400, and completing the cleaning work of the material.

[0067] When the first driving unit 530 works, its output end pushes the rotating shaft rod 570 to move. Since the first connecting rod 550 and the second connecting rod 560 are both rotationally connected with the rotating shaft rod 570, the movement of the rotating shaft rod 570 will drive the first connecting rod 550 and the second connecting rod 560 to move. The first connecting rod 550 is fixedly connected with the blade assembly 520, thereby driving the blade assembly 520 to rotate. The second connecting rod 560 is hingedly installed on the connecting rod frame 510, thereby providing support and constraint for the movement of the rotating shaft rod 570 and ensuring the stability of the whole transmission process.

[0068] Referring to Figure 2 and Figure 3 In some examples, the rotating axis of the blade assembly 520 and the connecting rod frame 510 is parallel to the rotating shaft rod 570.

[0069] As can be seen from the above, one end of the first connecting rod 550 is fixedly installed on the blade assembly 520, one end of the second connecting rod 560 is hingedly installed on the connecting rod frame 510, the other end of the first connecting rod 550 is rotationally installed on the rotating shaft rod 570, and the other end of the second connecting rod 560 is rotationally installed on the rotating shaft rod 570. The first driving unit 530 is hingedly installed on the base 100, and the output end of the first driving unit 530 is rotationally installed on the rotating shaft rod 570. For example, when the first driving unit 530 performs a contraction action, a pulling force in the direction of the base 100 is applied to the rotating shaft rod 570. The rotating shaft rod 570 pulls the blade assembly 520 to move in the movement process. Since the blade assembly 520 is hingedly connected with the connecting rod frame 510, the blade assembly 520 is rotated upward, i.e., in the direction of approaching the tail beam 400. In this action, the rotating axis of the blade assembly 520 and the connecting rod frame 510 needs to be parallel to the rotating shaft rod 570 to realize the above action. If the rotating axis of the blade assembly 520 and the connecting rod frame 510 is not parallel to the rotating shaft rod 570, the rotating axis of the blade assembly 520 and the connecting rod frame 510 will interfere with the rotating shaft rod 570 when the above action is realized, thereby affecting the normal work of the blade assembly 520.

[0070] Referring to Figure 2 and Figure 3 In some examples, the blade assembly 520 comprises a support bottom plate 521 hingedly installed on the connecting rod frame 510, and the first driving unit 530 is hingedly connected with the support bottom plate 521. An inclined blade 522 is arranged on the support bottom plate 521. The edge of the inclined blade 522 away from the base 100 is a first edge, and the edge of the inclined blade 522 close to the base 100 is a second edge. The distance between the inclined blade 522 and the support bottom plate 521 gradually increases in the direction from the first edge to the second edge.

[0071] In the technical scheme, the shovel plate assembly 520 comprises a support bottom plate 521 and an inclined shovel plate 522, the support bottom plate 521 is hingedly installed on the connecting rod frame 510, and the driving end of the first driving unit 530 is hingedly connected with the support bottom plate 521; when the first driving unit 530 operates, the support bottom plate 521 can rotate about the hinge shaft of the connecting rod frame 510, thereby driving the whole shovel plate assembly 520 to adjust the angle.

[0072] The inclined shovel plate 522 is obliquely installed on the support bottom plate 521, the edge of the inclined shovel plate 522 away from the base 100 is a first edge, the edge of the inclined shovel plate 522 close to the base 100 is a second edge, the distance between the inclined shovel plate 522 and the support bottom plate 521 gradually increases along the direction from the first edge to the second edge, the side of the inclined shovel plate 522 away from the base 100 is connected with the support bottom plate 521, and there is no gap between the inclined shovel plate 522 and the support bottom plate 521 at the position of the first edge; in the process of shoveling, the material is more likely to enter the inclined shovel plate 522 from the first edge, so that the inclined shovel plate 522 can cut into the material pile at a certain angle when working, which is more conducive to shoveling the material; compared with the horizontally arranged shovel plate, the inclined shovel plate 522 can utilize the component force generated by the inclination angle to reduce the resistance during shoveling and improve the shoveling efficiency.

[0073] Referring to Figure 2 and Figure 3 In some examples, the shovel plate assembly 520 further comprises a baffle 523 arranged on the support bottom plate 521 and connected with the second edge, and the included angle between the baffle 523 and the support bottom plate 521 ranges from 90° to 135°.

[0074] In the technical scheme, the shovel plate assembly 520 further comprises a baffle 523 arranged on the support bottom plate 521 and connected with the second edge, and the second edge of the inclined shovel plate 522 is the side edge close to the base 100; after the material is shovelled by the inclined shovel plate 522, the material moves along the inclined surface to the second edge, and the baffle 523 arranged at this position can effectively prevent the material from sliding backward, so that the material can be better collected and carried in the shovel plate assembly 520, and the efficiency of material cleaning and transportation is improved.

[0075] Exemplarily, when the included angle between the baffle 523 and the support bottom plate 521 is 90°, the baffle 523 is perpendicular to the support bottom plate 521, in this case, the baffle 523 can provide a more direct blocking effect, and has a good blocking effect on the vertically falling or horizontally moving materials, and can prevent the materials from overflowing from the rear of the support bottom plate 521 to the greatest extent; when the included angle reaches 135°, the baffle 523 has a certain inclination. Such a design makes the materials have a buffering process along the inclined surface of the baffle 523 after contacting the baffle 523, reduces the impact force of the materials on the baffle 523, and reduces the risk of damage to the baffle 523. When the included angle between the baffle 523 and the support bottom plate 521 is between 90° and 135°, the distance between the two baffles 523 can be adjusted flexibly according to different use cases.

[0076] Referring to Figure 2 and Figure 3 In some examples, the shovel plate assembly 520 further comprises a guard plate 524, which is symmetrically arranged on both sides of the inclined shovel plate 522 along the direction from the first edge to the second edge.

[0077] In this technical solution, the shovel plate assembly 520 further comprises the guard plate 524 which is symmetrically arranged on both sides of the inclined shovel plate 522, wherein the guard plate 524 is arranged along the direction from the first edge to the second edge of the inclined shovel plate 522. The first edge is the part that first contacts the materials during the work of the inclined shovel plate 522, and the materials are scooped up from here and moved along the inclined surface to the second edge. The guard plate 524 arranged on both sides of the inclined shovel plate 522 can constrain and protect the movement of the materials on the inclined shovel plate 522 throughout the process.

[0078] Exemplarily, when the inclined shovel plate 522 scoops up the materials, the materials will generate a certain lateral force on the inclined shovel plate 522. If the guard plate 524 is not symmetrically arranged, it may cause uneven force on both sides of the shovel plate assembly 520, thereby causing the shovel plate assembly 520 to deviate, sway and other unstable conditions during the movement. The symmetrical guard plate 524 can provide the same degree of constraint to the materials on both sides during the movement of the materials from the first edge to the second edge. In this way, the materials can be prevented from overflowing too much from one side, so that the materials can be more orderly accumulated and moved on the inclined shovel plate 522, and the efficiency and effect of material collection are improved.

[0079] Referring to Figure 2 and Figure 3 In some examples, the distance between the two guard plates 524 gradually decreases along the direction from the first edge to the second edge.

[0080] In the technical solution, the inclined shovel plate 522 starts to shovel the material from the first edge, and the material moves from the first edge to the second edge along with the movement of the shovel plate, the distance between the two guards 524 is designed to gradually decrease, like a funnel, which can guide the material to concentrate in the central area of the inclined shovel plate 522, so that more material can be gathered in the middle part of the shovel plate.

[0081] When the inclined shovel plate 522 shovels the material, the material moves along the inclined surface from the first edge to the second edge under the constraint of the guard 524, and because the distance between the two guards 524 gradually decreases, the material is continuously extruded by the two guards 524 during the movement, which reduces the gap between the materials and makes the materials more closely packed together, achieving the concentration of the material and the increase of the accumulation amount. By concentrating and increasing the accumulation amount of the material, the shovel plate assembly 520 can shovel more material in one operation, reducing the need for multiple shoveling due to the dispersion of the material, greatly improving the efficiency of shoveling; for loose materials such as coal and sand, this structure can effectively solve the problem of material dispersion and improve the collection and processing capacity of loose materials.
