Technical Field

[0002] Bucket elevators, as a type of continuous vertical material conveying machinery, are widely used in bulk material lifting systems in industries such as power, building materials, mining, conveying, grain, and feed.

[0003] When using bucket elevators to transport materials with high moisture content or viscous materials, material often adheres to the inner walls of the buckets, and this material is difficult to remove automatically even when the buckets enter the return section. This material adhering to the inner walls of the buckets can lead to anything from a decrease in the bucket's conveying capacity to, in severe cases, overload and tripping of the bucket elevator's drive motor.

[0004] The common current method involves manually striking the buckets with a hammer through the inspection port on the bucket elevator casing to shake off the material adhering to the inner wall of the buckets, thus emptying the buckets after unloading. This method is highly dependent on manual labor, involves high work intensity, and has low work quality. Summary of the Invention

[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0037] In order to make the technical personnel in the technical field better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0038] Please refer to Figures 1 to 8 , Figure 1 Structure diagram of the hammer provided by the embodiment of the present application; Figure 2 Design principle diagram of the hammer provided by the embodiment of the present application; Figure 3 Structure diagram of the hammer provided by the embodiment of the present application; Figure 4 Structure diagram of the hammer provided by the embodiment of the present application; Figure 5 Structure diagram of the hammer provided by the embodiment of the present application; Figure 6 Structure diagram of the hammer provided by the embodiment of the present application; Figure 5 Structure diagram of the hammer provided by the embodiment of the present application; Figure 7A structure diagram of a rigid hammer head provided by an embodiment of the present application is shown in the figure. Figure 8 A structure diagram of a mounting seat provided by an embodiment of the present application is shown in the figure.

[0039] Please refer to Figure 1 and Figure 2 The present application provides a rapping device, which comprises at least two rapping hammers, all of which are adjacent to an object 01 to be struck; any one of the rapping hammers can comprise a rotating shaft 1 and a plurality of hammer arms 2 arranged around the rotating shaft 1, the rotating shaft 1 can be fixedly rotated, and the rotating shaft 1 can drive all the hammer arms 2 arranged thereon to rotate synchronously when the rotating shaft 1 rotates; the aforementioned hammer arm 2 has a rigid hammer head 21 and an elastic hammer rod I 22 connected thereto, and the two ends of the elastic hammer rod I 22 are connected to the rotating shaft 1 and the rigid hammer head 21 respectively; the ideal trajectories of the rigid hammer heads 21 of any two adjacent rapping hammers are coplanar and partially coincide with each other, and at the same time, the ideal trajectory of the rigid hammer head 21 of any one of the rapping hammers is used to be coplanar and partially coincide with the moving trajectory of the object 01 to be struck, and it can be seen that all the rapping hammers are distributed along the moving trajectory of the object 01 to be struck in turn. Among them, the ideal trajectory of the rigid hammer head 21 of the rapping hammer refers to the circular trajectory formed by the outer end of the rigid hammer head 21 when the elastic hammer rod I 22 is not deformed. Similarly, the ideal trajectory of the elastic hammer rod I 22 mentioned below refers to the circular trajectory formed by the outer end of the elastic hammer rod I 22 when the elastic hammer rod I 22 is not deformed.

[0040] In this embodiment, the ideal trajectory of the rigid hammer head 21 of any one of the rapping hammers is coplanar and partially coincides with the moving trajectory of the object 01 to be struck, so that the rigid hammer head 21 of the rapping hammer and the object 01 to be struck can collide in the overlapping area of the two, and the rigid hammer head 21 and the object 01 to be struck that collide with each other can transmit force to each other, realizing transmission connection; the ideal trajectories of the rigid hammer heads 21 of any two adjacent rapping hammers are coplanar and partially coincide with each other, so that the rigid hammer heads 21 of the two adjacent rapping hammers can collide in the overlapping area of the two, and the two rigid hammer heads 21 that collide with each other can transmit force to each other, realizing transmission connection.

[0041] For the entire rapping device, all the rapping hammers are distributed along the moving trajectory of the object 01 to be struck in turn. When the object 01 to be struck moves to the first rapping hammer among all the rapping hammers, the object 01 to be struck can collide with the rigid hammer head 21 of the first rapping hammer, realizing the transmission of kinetic energy of the object 01 to be struck to the first rapping hammer, so as to drive the first rapping hammer to rotate, then the rotating first rapping hammer can collide with the rigid hammer head 21 of the second rapping hammer adjacent to the first rapping hammer, realizing the transmission of kinetic energy of the first rapping hammer to the second rapping hammer, so as to drive the second rapping hammer to rotate, and the same is true for the subsequent rapping hammers. It can be seen that once the object 01 to be struck drives the first rapping hammer among all the rapping hammers to rotate, the first rapping hammer and the remaining rapping hammers will be transmitted in turn, realizing the rotation of each rapping hammer around the respective rotating shaft 1 and the dynamic operation of all the rapping hammers.

[0042] Since all the beating hammers are arranged along the moving track of the object to be struck 01 in sequence, and the ideal track of the rigid hammer head 21 of any beating hammer is coplanar and partially coincident with the moving track of the object to be struck 01, all the beating hammers of the beating device can collide with the object to be struck 01.

[0043] Among them, the first beating hammer is driven to rotate by the object to be struck 01, and the first beating hammer can be regarded as a driven part of the object to be struck 01. Although the interaction force when the two collide with each other can have a certain striking effect on the object to be struck 01, the striking and beating effect is generally poor. The remaining beating hammers except the first beating hammer are driven to rotate by the adjacent beating hammers in front of them, and the remaining beating hammers except the first beating hammer can be regarded as driving parts. When the object to be struck 01 passes through these beating hammers, these beating hammers can actively hit the object to be struck 01, and good striking and beating effects can be achieved. As can be seen, all the beating hammers of the beating device complement each other, can run with the kinetic energy of the object to be struck 01 as power, and do not need to specially set up power equipment, and can effectively strike and beat the object to be struck 01.

[0044] All the beating hammers of the beating device are driven in sequence, and all the beating hammers can strike and beat the object to be struck 01 passing through them. This not only requires that the movements of all the beating hammers are related to each other and do not interfere with each other, but also requires that the movements of all the beating hammers and the object to be struck 01 are related to each other and do not interfere with each other. Therefore, it is necessary to reasonably design the processing parameters, installation parameters and operation parameters of the beating device, its beating hammers and the object to be struck 01.

[0045] Generally, a beating device is provided with two beating hammers, and the object to be struck 01 can be struck and beaten by one or more beating devices, which can simplify the design of various parameters such as the processing parameters, installation parameters and operation parameters of the beating device, its beating hammers and the object to be struck 01, and can also ensure that the beating device and its beating hammers can reasonably and effectively beat the object to be struck 01.

[0046] In addition, in this embodiment, the beating hammer strikes the object to be struck 01 or the rigid hammer head 21 of the adjacent beating hammer by using the rigid hammer head 21, and the rigid hammer head 21 is arranged on the rotating shaft 1 through the elastic hammer rod I22. The arrangement of the aforementioned elastic hammer rod I22 can not only reasonably control the force applied by the rigid hammer head 21 to the object to be struck 01, so as to avoid the object to be struck 01 being struck and flattened due to the excessive force applied by the rigid hammer head 21 to the object to be struck 01, but also is conducive to coordinating the movement relationship among the beating hammer, the object to be struck 01 and the adjacent beating hammer, so as to avoid the beating device or the device where the object to be struck 01 is located from being jammed and stopped.

[0047] In summary, the vibration device provided by the present application can be driven by the moving object to be struck 01, so that all the vibration hammers rotate around their respective rotating shafts 1, and when all the vibration hammers rotate, they can strike and vibrate the object to be struck 01 passing by, thereby exerting a reasonable and effective vibration effect on the object to be struck 01.

[0048] The vibration device provided by the present application can be used for striking and vibrating the hopper of a bucket elevator, for example, to loosen the material in the hopper before unloading, or to empty the hopper after unloading.

[0049] The vibration device provided by the present application will be further described below in combination with the drawings and embodiments.

[0050] Still referring to Figure 1 and Figure 2 , as can be seen, the ideal trajectory of the rigid hammer head 21 of any two adjacent vibration hammers is coplanar and partially coincident, and the ideal trajectory of the rigid hammer head 21 of any vibration hammer is coplanar and partially coincident with the moving trajectory of the object to be struck 01, so that the vibration hammer can strike the rigid hammer head 21 of the adjacent vibration hammer with its rigid hammer head 21, thereby achieving transmission between the adjacent vibration hammers, and the vibration hammer can strike the object to be struck 01 passing by with its rigid hammer head 21, thereby achieving transmission between the vibration hammer and the object to be struck 01. On this basis, in order to ensure the smoothness of the movement between the adjacent vibration hammers, the vibration hammer and the object to be struck 01, in some embodiments, the ideal trajectory of the rigid hammer head 21 of any vibration hammer is separated from the ideal trajectory of the elastic hammer rod I 22 of the adjacent vibration hammer, and the ideal trajectory of the elastic hammer rod I 22 of any vibration hammer is used to separate from the moving trajectory of the object to be struck 01.

[0051] The ideal trajectory of the rigid hammer head 21 of the vibration hammer is separated from the ideal trajectory of the elastic hammer rod I 22 of the adjacent vibration hammer, and the ideal trajectory of the elastic hammer rod I 22 of the vibration hammer is used to separate from the moving trajectory of the object to be struck 01, which limits the relative position relationship between the adjacent vibration hammers and the relative position relationship between any vibration hammer and the object to be struck 01, so that the rigid hammer head 21 of the vibration hammer only strikes the object to be struck 01 and the rigid hammer head 21 of the adjacent vibration hammer, avoiding the distance between the adjacent two vibration hammers being too small, so that the rigid hammer head 21 of the vibration hammer strikes the elastic hammer rod I 22 of the adjacent vibration hammer, and the vibration hammer only uses the rigid hammer head 21 to strike the object to be struck 01, avoiding the elastic hammer rod II 23 of the vibration hammer contacting the object to be struck 01 and affecting the striking and vibrating effect on the object to be struck 01.

[0052] Please refer to Figure 1 , Figure 3 , Figures 5 to 7, on the basis of the above-mentioned embodiments, the hammer arm 2 of the beating hammer further comprises a resilient hammer rod II 23; the resilient hammer rod I 22, the resilient hammer rod II 23 and the rigid hammer head 21 are sequentially connected; the resilient hammer rod II 23 is arranged in the rigid hammer head 21, in other words, the rigid hammer head 21 wraps the resilient hammer rod II 23; the resilient hammer rod II 23 is between the resilient hammer rod I 22 and the rigid hammer head 21, in other words, the resilient hammer rod I 22 connects the rigid hammer head 21 through the resilient hammer rod II 23.

[0053] Generally, the resilient hammer rod I 22 can be integrally formed with the resilient hammer rod II 23, and the two can be respectively regarded as two ends of the resilient hammer rod, and the two ends of the resilient hammer rod are respectively connected to the rotating shaft 1 and the rigid hammer head 21.

[0054] For reference Figures 5 to 7 In some embodiments, the size of the rigid hammer head 21 along the normal plane direction of the rotating shaft 1 tapers from the root to the head, that is, the root of the rigid hammer head 21 is thicker than the head of the rigid hammer head 21 along the normal plane direction of the rotating shaft 1, and vice versa. The head of the rigid hammer head 21 is thinner than the root of the rigid hammer head 21. The aforementioned rigid hammer head 21 along the normal plane direction of the rotating shaft 1 is a smooth transition acute angle, that is, the rigid hammer head 21 is an acute angle along the normal plane direction of the rotating shaft 1, and the acute angle end of the rigid hammer head 21 is smoothly transitioned to form a smooth curved surface. In addition, the rigid hammer head 21 along its common plane with the rotating shaft 1 is a rectangular plate, that is, any one rigid hammer head 21 and the rotating shaft 1 are in the same plane, and the rigid hammer head 21 is a rectangular plate along the plane.

[0055] In the above-mentioned embodiments, the root of the rigid hammer head 21 is thicker than the head of the rigid hammer head 21 along the normal plane direction of the rotating shaft 1, and the head of the rigid hammer head 21 is an acute angle and has a smooth surface, which can quickly and effectively knock and beat the object to be knocked 01, and can guarantee the relative movement between the rigid hammer head 21 and the object to be knocked 01; along the common plane of the rigid hammer head 21 and the rotating shaft 1, the rigid hammer head 21 is a rectangular plate, and in combination with the shape of the rigid hammer head 21 along the normal plane direction of the rotating shaft 1, the rigid hammer head 21 presents a flat and wide plate body shape as shown in Figure 5 and Figure 6 which is beneficial to smoothly knock the object to be knocked 01, and can appropriately increase the contact area with the object to be knocked 01, and guarantee the knocking and beating effect on the object to be knocked 01.

[0056] For reference Figure 3 , Figure 4 and Figure 8In some embodiments, the beating hammer further comprises a mounting seat 3, the mounting seat 3 is sleeved and fixed on the rotating shaft 1, the mounting seat 3 is provided with a plurality of rigid mounting plates 31 on the circumferential side, all the rigid mounting plates 31 are distributed radially around the mounting seat 3, or in other words, all the rigid mounting plates 31 are distributed in a ring around the mounting seat 3 and the rotating shaft 1. In this embodiment, the hammer arm 2 is connected to the rotating shaft 1 through the mounting seat 3 and its rigid mounting plates 31, as shown in Figure 3 and Figure 4 , all the rigid mounting plates 31 are connected to all the elastic hammer rods I22 one by one. The mounting seat 3 and its rigid mounting plates 31 can realize the connection of the elastic hammer rod I22 and the rotating shaft 1, which can simplify the processing and installation of the elastic hammer rod I22, and also facilitate the separate replacement of the hammer arm 2 in the beating hammer, so that the hammer arm 2 can be replaced in time when the rigid hammer head 21 is severely worn or the elastic hammer rod I22 is severely aged.

[0057] Generally, one beating hammer is provided with three or more hammer arms 2, all the hammer arms 2 are uniformly and circularly distributed around the rotating shaft 1, correspondingly, the mounting seat 3 is provided with three or more rigid mounting plates 31, the number of all the rigid mounting plates 31 can be equal to the number of all the hammer arms 2, one rigid mounting plate 31 is connected to one hammer arm 2.

[0058] In addition, in some embodiments, the device in which the to-be-struck object 01 is located is provided with a device shell 02, the to-be-struck object 01 is arranged in the device shell 02, and at the same time, the beating device provided by the present application is also arranged in the aforementioned device shell 02.

[0059] As shown in Figure 1 and Figure 4 , the beating device is provided with a bearing seat 4 and a fixing seat 5, both the bearing seat 4 and the fixing seat 5 can be arranged at the end of the rotating shaft 1, for example, both ends of the rotating shaft 1 are provided with the bearing seat 4 and the fixing seat 5. Taking any one end of the rotating shaft 1 as an example, the bearing seat 4 is sleeved on the rotating shaft 1, and the bearing seat 4 is fixed on the fixing seat 5, and the fixing seat 5 is used for fixedly connecting the inner wall of the device shell 02, so that the rotating shaft 1 is positioned and arranged in the device shell 02. Generally, the device shell 02 is provided with an inspection observation hole aligned with the beating device, so as to facilitate the installation, disassembly and maintenance of the beating device.

[0060] As mentioned above, one beating device is generally provided with two beating hammers. As shown in Figure 1 and Figure 2 , the beating device has two beating hammers, the connecting line of the shaft centers of the two beating hammers is parallel to the moving track of the to-be-struck object 01, and the following gives the product design and installation relationship of the beating device to meet the beating operation requirements of the to-be-struck object 01:

[0061] The two beating hammers and the to-be-struck object 01 meet the following formula:

[0062]

[0063] a < R ≤ b (2);

[0064]

[0065] 2R - H < L < 2R (4);

[0066]

[0067]

[0068] In the above formula (1) to formula (6), L is the axial distance of the two beating hammers, R is the length of the hammer arm 2, H is the length of the rigid hammer head 21, θ is the angle of the central angle corresponding to the two intersection points of the plane where the outer edge of the object to be struck 01 is located and the ideal trajectory of the rigid hammer head 21, n is the number of hammer arms 2 of any one beating hammer, α is the angle of the central angle corresponding to the two intersection points of the ideal trajectories of the rigid hammer heads 21 of the two beating hammers, B is the distance between the two objects to be struck 01 that contact the beating device in sequence, a is the distance between the plane where the outer edge of the object to be struck 01 is located and the plane where the inner edge is located, b is the distance between the plane where the inner edge of the object to be struck 01 is located and any one rotating shaft 1, and c is the distance between the axis of any one beating hammer and the connecting line of the two adjacent hammer arms 2.

[0069] wherein, Figure 2 Two dashed lines and one solid line are marked in sequence from left to right, passing through Figure 2 the right side of the solid line and perpendicular to Figure 2 the plane of the paper surface can be regarded as the plane where the inner edge of the object to be struck 01 is located, passing through Figure 2 the right side of the dashed line and perpendicular to Figure 2 the plane of the paper surface can be regarded as the plane where the outer edge of the object to be struck 01 is located, and passing through Figure 2 the left side of the dashed line and perpendicular to Figure 2 the plane of the paper surface can be regarded as the plane where the rotating shaft 1 of the two beating hammers is located.

[0070] Figure 2 Two dashed circles and two solid right-angle sectors are also marked, and the two dashed circles can be regarded as the ideal trajectories of the rigid hammer heads 21 of the two beating hammers, respectively, and the two solid right-angle sectors refer to the two objects to be struck 01 that contact the beating device in sequence.

[0071] In addition, for convenience of description, the beating hammer above Figure 2 will be referred to as the first beating hammer, and the beating hammer below Figure 2 will be referred to as the second beating hammer.

[0072] When two beating hammers and the object 01 to be struck satisfy the above formula (1), two or more objects 01 to be struck that successively contact the beating device can enter the working area of the beating device one by one, that is, the object 01 to be struck that enters the working area of the first beating hammer first can contact and drive the first beating hammer to rotate, the first beating hammer can contact and drive the second beating hammer to rotate when the first beating hammer rotates, and then the aforementioned object 01 to be struck leaves the working area of the first beating hammer and enters the working area of the second beating hammer, the second beating hammer strikes and beats the aforementioned object 01 to be struck, and after the aforementioned object 01 to be struck leaves the working area of the second beating hammer, the next object 01 to be struck enters the working area of the first beating hammer and coincides with the action of the previous object 01 to be struck. This can ensure that the beating device strikes and beats multiple objects 01 to be struck one by one, avoid two or more objects 01 to be struck from entering the working area of the beating device at the same time, and avoid disturbing the movement rules of the two beating hammers of the beating device.

[0073] When two beating hammers and the object 01 to be struck satisfy the above formula (2) and formula (3), it can be ensured that both beating hammers can strike and beat the object 01 to be struck along the way.

[0074] When two beating hammers satisfy the above formula (4) and formula (5), it can be ensured that the rigid hammer heads 21 of the two beating hammers can contact and drive each other, achieving transmission connection, and it can also be avoided that the rigid hammer head 21 of any beating hammer contacts the elastic hammer rod I22 of the other beating hammer, avoiding the phenomenon that the two beating hammers are stuck to each other.

[0075] When two beating hammers and the object 01 to be struck satisfy the above formula (6), the hopper can only contact one hammer arm 2 when passing through the working area of any beating hammer, that is, each beating hammer only uses one hammer arm 2 to strike and beat the object 01 to be struck. Of course, each beating hammer can also use two or more hammer arms 2 to strike and beat the object 01 to be struck.
