When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0064] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The singular forms of "a", "said" and "the" used in this application and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0065] The present application will be described in detail below through examples.

[0066] In the prior art, in coal mines and other working scenarios, it is usually necessary to transport materials such as coal slag and soil from underground to a designated location via a conveyor belt. After working for a long time, some materials may stick to the surface of the conveyor belt, resulting in a decrease in the conveying capacity of the conveyor belt, and even damage to structures such as bearings or gears due to materials falling into the equipment. The current conveyor belt cleaners are not effective in handling large or highly adhesive attachments, and may even easily cause damage to the cleaners during the cleaning process.

[0067] In order to solve the technical problems existing in the existing dredging equipment in the background technology, the inventive concept of the present application is to provide a sweeper and a material conveying equipment having the sweeper to solve at least one technical problem mentioned in the background technology. Wherein, the sweeper is arranged on the conveying device, including: a first mounting plate and a second mounting plate arranged at intervals; a transmission rod, the transmission rod passes through the first mounting plate and the second mounting plate; a scraper, fixedly arranged on the transmission rod, rotates with the transmission rod, and is located between the first mounting plate and the second mounting plate; a damping device, including a connecting body, a positioning plate, and an elastic body; the connecting body is located on the side of the first mounting plate away from the scraper, and rotates with the transmission rod; one end of the connecting body is connected to the transmission rod, and the other end is connected to the elastic body; one end of the positioning plate is rotatably installed on the side of the first mounting plate away from the scraper; a releasing device, the releasing device includes a stop mechanism, and the stop mechanism includes at least a first position and a second position on the first mounting plate; when the stop mechanism is in the first position, it is located on the side of the positioning plate away from the connecting body, and abuts against the positioning plate; when the stop mechanism is in the second position, the positioning plate no longer limits the elastic body.

[0068] According to the inventive concept, by setting a release device, the elastic body of the sweeper can be detached when the force is too great, thereby avoiding damage to the sweeper or material conveying equipment caused by overload of the sweeper, thereby improving the safety and use efficiency of the product.

[0069] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0070] Based on the inventive concept of the present application, in some preferred embodiments of the present application, a cleaner is provided on the conveying device, such as Figure 1-Figure 2 As shown, including:

[0071] A first mounting plate 11 and a second mounting plate 21 are arranged at intervals; the sweeper is fixed on a conveying device through the first mounting plate 11 and the second mounting plate 21, and the conveying device includes a conveyor belt. The installation position of the sweeper enables it to clean foreign objects on the conveyor belt.

[0072] The transmission rod 30 passes through the first mounting plate 11 and the second mounting plate 21; and the transmission rod 30 can rotate relative to the first mounting plate 11 and the second mounting plate 21; in some embodiments, bearings are provided at the position where the transmission rod 30 contacts the first mounting plate 11 and the second mounting plate 21 to reduce the friction force when the transmission rod 30 rotates relative to each other.

[0073] The scraper 40 is fixedly mounted on the transmission rod 30, rotates with the transmission rod 30, and is located between the first mounting plate 11 and the second mounting plate 21; when working, the scraper 40 contacts the surface of the conveyor belt. When the conveyor belt moves, foreign matter is cleaned by the scraper 40 because it is higher than the plane of the conveyor belt.

[0074] The damping device includes a connecting body 51, a positioning plate 52, and an elastic body 53; the connecting body 51 is located on the side of the first mounting plate 11 away from the scraper 40, and rotates with the transmission rod 30; one end of the connecting body 51 is connected to the transmission rod 30, and the other end is connected to the elastic body 53; one end of the positioning plate 52 is fixed to the side of the first mounting plate 11 away from the scraper 40;

[0075] The release device includes a stop mechanism 61 , and the stop mechanism 61 includes at least a first position and a second position on the first mounting plate 11 .

[0076] When the stop mechanism 61 is located at the first position, it is located on the side of the positioning plate 52 away from the connecting body 51 and abuts against the positioning plate 52; when the scraper 40 contacts the foreign matter on the conveyor belt, it drives the transmission rod 30 to rotate ( Figure 1-Figure 2 In the embodiment of the transmission rod 30, the transmission rod 30 will rotate in the clockwise direction), the transmission rod 30 continues to drive the connecting body 51 to rotate, so that the connecting body 51 applies pressure to the positioning plate 52 through the elastic body 53. As the rotation amplitude of the transmission rod 30 increases, the force applied by the elastic body 53 to the positioning plate 52 will also increase.

[0077] When the stop mechanism 61 is located at the second position, the positioning plate 52 no longer limits the elastic body 53; that is, when the stop mechanism 61 gradually moves from the first position until it moves to the second position, the stop mechanism 61 and the positioning plate 52 are no longer in contact, thereby releasing the positioning plate 52 and making one end of the elastic body 53 a free end, thereby releasing the pressure.

[0078] By adopting the above technical solution and setting a release device, the elastic body of the sweeper can be detached when the force is too great, thereby avoiding damage to the sweeper or material conveying equipment caused by sweeper overload, thereby improving the safety and use efficiency of the product.

[0079] In some preferred embodiments, the scraper 40 includes a first mounting portion 41 and a blade body 42. The first mounting portion 41 is arranged on the transmission rod 30 through a fixing device. The blade body is fixedly arranged on the first mounting portion 41. The first mounting portion 41 is made of a first material, and the blade body 42 is made of a second material, and the first material is different from the second material; wherein the first material has a harder hardness than the second material. In some embodiments, the first material is selected from a metal material, such as an aluminum alloy, and the second material is selected from a non-metal material, such as polyurethane. By adopting the above technical solution, the first mounting portion is prepared using a material with a higher hardness, so that the blade body can be fixed more firmly, and the use of polyurethane with a relatively lower hardness as the material of the blade body can ensure that the blade body has a certain scraping ability and is appropriately worn to avoid damage to the conveyor belt.

[0080] In some preferred embodiments, reference Figure 3 The first mounting portion 41 includes a first mounting groove 411 and a second mounting groove 412 arranged at intervals, and a third mounting groove 413 arranged between the first mounting groove 411 and the second mounting groove 412, the first mounting groove 411 and the second mounting groove 412 cooperate with the blade body 42, and the third mounting groove 413 cooperates with the fixing device, wherein the fixing device is a vertically arranged fixing plate 31; wherein, in some embodiments, the first mounting groove 411 and the second mounting groove 412 are connected by a first connecting plate 414, and a first reinforcing plate 4141 and a second reinforcing plate 4142 are respectively extended to the first mounting groove 411 and the second mounting groove 412 on both sides of the first connecting plate 414, the first reinforcing plate 4141 and the first connecting plate 414 generate a first angle, and the second reinforcing plate 4142 and the first connecting plate 414 generate a second angle, and the first angle and the second angle are different; the first reinforcing plate 4141 extends in a direction toward the transmission rod 30, and the second reinforcing plate 4142 extends in a direction away from the transmission rod 30.

[0081] By adopting the above technical solution, the scraper is fixed to the transmission rod through the third mounting groove, and the blade body is fixed to the first mounting part through the first mounting groove and the second mounting groove, which can ensure the stability of the scraper during the cleaning process and improve the cleaning efficiency.

[0082] In some preferred embodiments, continue to refer to Figure 3 The end of the blade body 42 has a blade 421 for removing foreign matter from the conveyor belt, and the first mounting groove 411 is located on the side of the fixing plate 31 closer to the blade 421 than the second mounting groove 412. With the above technical solution, since the blade is easily impacted by foreign matter, the blade head is easily deformed in the direction away from the blade, and the first mounting groove is arranged on the side close to the blade, so that the first reinforcing plate can provide downward support for the deformation of the blade body, thereby reducing the deformation tendency of the blade body after being impacted by foreign matter.

[0083] In some preferred embodiments, reference Figure 4 As shown, the first mounting groove 411 includes a first side plate 4111 and a second side plate 4112 which are arranged at intervals, the second side plate 4112 is connected to the fixing plate 31, and the first side plate 4111 has a third reinforcing plate 4113 at one end away from the transmission rod, and the third reinforcing plate 4113 extends toward the second side plate 4112. By adopting the above technical solution, the fixing stability of the first mounting portion and the blade body can be improved by providing the third reinforcing plate, thereby ensuring the safety of the sweeper during operation.

[0084] Similarly, the second mounting groove 412 includes a third side plate 4121 and a fourth side plate 4122 that are spaced apart. The fourth side plate 4122 is connected to the fixing plate 31 . The end of the third side plate 4121 away from the transmission rod has a fourth reinforcing plate 4123 , and the fourth reinforcing plate 4123 extends toward the fourth side plate 4122 .

[0085] By adopting the above technical solution, the fixing stability of the scraper and the transmission rod can be improved by clamping the fixing plate between the third reinforcing plate and the fourth reinforcing plate.

[0086] In some preferred embodiments, see Figure 5-Figure 6 The connecting body 51 includes a first connecting portion 511 connected to the transmission rod 30, a third connecting plate 512 extending outward from the first connecting portion 511, and a second connecting portion 513 is formed at the end of the third connecting plate 512; specifically, the second connecting portion 513 includes a fourth mounting groove, and one end of the elastomer 53 is arranged in the fourth mounting groove; in some embodiments, the fourth mounting groove includes at least an upward opening, so that the elastomer 53 remains relatively stable in the fourth mounting groove under the action of gravity.

[0087] In some preferred embodiments, see Figure 5-Figure 6 , the elastic body 53 comprises:

[0088] The second mounting portion 531 is arranged in the fourth mounting groove, the first connecting rod 532 connected to the second mounting portion 531 at one end, the first positioning piece 533, the second positioning piece 534, and the elastic member 535 are sleeved on the first connecting rod 532; when the stop mechanism 61 is located at the first position, the first positioning piece 533 abuts against the positioning plate 52, the elastic member 535 is located between the first positioning piece 533 and the second positioning piece 534, and is subjected to the pressure of the first positioning piece 533 and the second positioning piece 534; specifically, the first connecting rod 532 can be a screw rod; the elastic member 535 can be a spring sleeved on the first connecting rod 532. By providing the first positioning piece and the second positioning piece, the elastic member can be limited, and the elastic force of the elastic member can be transmitted to the positioning plate. In addition, the second mounting portion is matched with the fourth mounting groove, which can facilitate the installation and release of the elastic body, and the structure is simple and safe.

[0089] In some preferred embodiments, a positioning block 536 is movably provided on the first connecting rod 532. When the stopping mechanism 61 is located at the first position, the positioning block 536 is located on the side of the second positioning piece away from the first positioning piece 533, and abuts against the second positioning piece 534. In some embodiments, the positioning block 536 is a nut that can move on the first connecting rod 532. By adjusting the position of the positioning block 536, the spacing between the first positioning piece 533 and the second positioning piece 534 can be adjusted, thereby affecting the elastic force of the elastic member 535, thereby realizing rapid equipment adjustment.

[0090] In some preferred embodiments, see Figure 7 The positioning plate 52 has a first receiving groove 521, which is located on a side of the positioning plate 52 close to the connector. When the stop mechanism 61 is located at the first position, the first positioning piece 533 cooperates with the first receiving groove 521 to improve the installation stability between the first positioning piece and the positioning plate.

[0091] In some preferred embodiments, see Figure 5-Figure 6 The positioning plate 52 has a first through hole 522. When the stop mechanism 61 is located at the first position, the first connecting rod 532 is disposed through the first through hole 522. The above technical solution can reduce the weight of the positioning plate on the one hand, and reduce the restriction on the length of the first connecting rod on the other hand, making its installation more flexible.

[0092] In some preferred embodiments, see Figure 5-Figure 6, the release device includes a driving mechanism, and the stop mechanism 61 moves from the first position to the second position under the action of the driving mechanism; in some embodiments, the stop mechanism 61 includes a stop rod 611 and a pull ring 612 arranged on the stop rod 611, and the stop rod 611 is movably arranged on the first mounting plate 11, and when the stop mechanism is in the first position, the stop rod 611 abuts against the positioning plate 52 to maintain the normal cleaning state of the sweeper; the driving mechanism includes a driving rod 62, one end of which is connected to the first connecting portion 511 and rotates therewith. Specifically, when the stop mechanism 61 is in the first position, one end of the driving rod 62 away from the first connecting part is passed through the pull ring 612, and when the driving rod 62 rotates with the first connecting part 511, the pull ring 612 is driven to move from the first position to the second position; when the pull ring 612 reaches the second position, the stop rod 611 is no longer in contact with the positioning plate 52, so that one end of the positioning plate 52 becomes a movable end, causing the elastic member 535 to detach from the positioning plate 52. At this time, the elastic body 53 cannot provide support for the connecting body 51, so that the connecting body 51 is released, and the sweeper changes from the conventional cleaning state to the released state to avoid wear of the scraper or the conveyor belt. Therefore, the driving mechanism can only drive the stop mechanism from the first position to the second position in one direction, but cannot drive the stop mechanism from the second position to the first position, so as to ensure that the sweeper can quickly change to the released state after encountering greater pressure for inspection by the staff to avoid danger.

[0093] In some embodiments, the first mounting plate 11 has a longitudinally arranged movable groove 11, and the stopper rod 611 can move in the movable groove 11 to realize the conversion between the first position and the second position; however, in some embodiments, the stopper rod 611 cannot rotate in the movable groove 11 to ensure the cooperation effect between the driving rod 62 and the pull ring 612. With the above technical solution, by setting one end of the driving rod at the first connecting part, the driving rod controls the stopper rod along with the action of the scraper, which has a simple structure and is easy to install and repair; on the other hand, the cooperation between the driving rod and the pull ring is more conducive to the installation and release of the structure.

[0094] Further, see Figure 6 The driving rod 62 includes a first rod segment 621, a second rod segment 622, and a third rod segment 623 which are connected in sequence. The first rod segment 621 and the third rod segment 623 are parallel or almost parallel to the horizontal plane, and the third rod segment 623 is higher than the first rod segment 621; the second rod segment 622 intersects with the first rod segment 621 and the third rod segment 623 at an obtuse angle; such an arrangement can improve the transmission capacity and mechanical strength of the driving rod 62 when the driving rod 62 drives the pull ring 612.

[0095] In some embodiments, the sweeper also includes a third mounting plate 12, and the damping device and the release device are installed between the first mounting plate 11 and the third mounting plate 12; specifically, one end of the positioning plate 52 is clamped between the first mounting plate 11 and the third mounting plate 12, and the stop rod 611 is clamped between the first mounting plate 11 and the third mounting plate 12 to make the installation of the damping device and the release device more stable.

[0096] It can be understood that the damping device and the release device described in the present application can be installed on the first mounting plate 11 and the second mounting plate 21 at the same time; wherein, the sweeper also includes a fourth mounting plate 22, and the damping device and the release device can also be installed between the second mounting plate 21 and the fourth mounting plate 22.

[0097] In some other embodiments of the present application, a material conveying device is provided. Figure 8 ,include:

[0098] A conveyor belt 70 for transporting materials on a first surface 71 thereof;

[0099] The first roller 81 and the second roller 82 are arranged at both ends of the conveyor belt 70 in the length direction, and are used to drive the conveyor belt 70 to move;

[0100] The cleaner 10 as described in the above embodiment is arranged near the first roller 81 ; the scraper 40 abuts against the portion of the conveyor belt 70 located on the first roller 81 to clean foreign matter on the first surface 71 .

[0101] To sum up, the sweeper and material conveying equipment provided in the embodiments of the present invention, by providing a release device, can enable the sweeper to separate from the elastic body when the force is too large, thereby avoiding damage to the sweeper or the material conveying equipment caused by overload of the sweeper, solving the technical problems raised by the background technology, and achieving the technical effect of improving product safety and utilization efficiency.

[0102] It should be pointed out that for ordinary technicians in this field, the technical features in the above embodiments can be freely combined, and the formed technical solutions also belong to the embodiments disclosed in this application.

[0103] Furthermore, without departing from the principles of the present application, several improvements and modifications may be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
