Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and more specifically, to a connecting mechanism and a vibrating screen. Background Technology

[0002] Vibrating screens utilize the excitation force generated by a vibrating motor for screening, and belong to the category of vibrating screening. Commonly used mining vibrating screens include circular vibrating screens and linear vibrating screens. For grading crushed materials, probability screens, equal-thickness screens, and large vibrating screens are used.

[0003] Existing vibrating screens mainly consist of a screen box, a motor drive, a vibrator, a vibration damping device, and a screen surface. The blind plate in the screen surface mainly serves to guide the material, and it is fixed by a mushroom head rail seat, a three-groove rail seat, a pressure rail, and a pressure plate. During operation, the blind plate is also subjected to high-frequency vibration of the vibrating screen and may become loose. If this is not detected in time, the blind plate may fall off, resulting in material mixing, clogging of subsequent screens, and even damage to the machine, increasing maintenance costs and reducing production efficiency. Utility Model Content

The first mounting member 91 has a first mounting hole 911, and a slot 912 is provided on the hole wall of the first mounting hole 911.

[0033] The connecting mechanism includes at least one connecting component 10; each connecting component 10 is used to connect a first mounting member 91 and a second mounting member 92; the connecting component 10 includes a connecting body 11 and a snap-fit ​​portion 12; the connecting body 11 is fixedly inserted through the second mounting member 92 and inserted through the first mounting hole 911 of the first mounting member 91; the snap-fit ​​portion 12 is telescopically disposed on the connecting body 11 along a preset direction, the preset direction being set at an angle to the insertion direction of the connecting body 11, so that the snap-fit ​​portion 12 has an avoidance state located within the connecting body 11 and a snap-fit ​​state at least partially protruding from the connecting body 11.

[0034] By positioning the snap-fit ​​portion 12 in an abdicating state, the connecting body 11 can be inserted into the second mounting member 92 and into the first mounting hole 911 of the first mounting member 91.

[0035] When the connecting body 11 passes through the second mounting member 92 and into the first mounting hole 911 of the first mounting member 91, the snap-fit ​​part 12 is in a snap-fit ​​state. When the snap-fit ​​part 12 is in a snap-fit ​​state, the part of the snap-fit ​​part 12 extending out of the connecting body 11 is located in the slot 912 of the first mounting member 91, so that the connecting body 11 is snap-fitted and fixed to the first mounting member 91 through the snap-fit ​​part 12.

[0036] Optionally, the snap-fit ​​part 12 is a block structure.

[0037] In this application, the second mounting member 92 has a second mounting hole 921, and the connecting body 11 is used to be fixedly installed inside the second mounting hole 921.

[0038] Specifically, the axial direction of the first mounting hole 911 is the same as that of the second mounting hole 921.

[0039] In this application, the connecting body 11 has a telescopic hole 111, the axis of which is the same as a preset direction; the snap-fit ​​part 12 is telescopically disposed in the telescopic hole 111; the outer end of the telescopic hole 111 extends to the outer wall surface of the connecting body 11, so that at least a portion of the snap-fit ​​part 12 can extend out of the connecting body 11 from the outer end of the telescopic hole 111, thereby changing the snap-fit ​​part 12 from an avoidance state to a snap-fit ​​state.

[0040] In this application, a plurality of slots 912 are provided on the circumferential side of the wall of the first mounting hole 911, and there are a plurality of snap-fit ​​parts 12, with each snap-fit ​​part 12 corresponding to a snap-fit ​​part 912.

[0041] By positioning the multiple snap-fit ​​parts 12 in an abutment state, the connecting body 11 is inserted into the second mounting member 92 and into the first mounting hole 911 of the first mounting member 91. Once the connecting body 11 is inserted into the second mounting member 92 and into the first mounting hole 911 of the first mounting member 91, the multiple snap-fit ​​parts 12 are in a snap-fit ​​state. The portion of each snap-fit ​​part 12 extending from the connecting body 11 is located within a corresponding slot 912, thereby securing the connecting body 11 to the first mounting member 91 through the multiple snap-fit ​​parts 12.

[0042] Optionally, an annular groove is formed on the wall of the first mounting hole 911, and the annular groove includes multiple slots 912; that is, the multiple slots 912 are all connected along the circumference of the first mounting hole 911 to form an annular groove.

[0043] In this application, the connecting component 10 includes an elastic component 13; the two ends of the elastic component 13 along its extension direction are respectively connected to two snap-fit ​​portions 12 to connect the two snap-fit ​​portions 12.

[0044] When the elastic component 13 is in its initial state, both of its connected latching parts 12 are in a clearance state; as the two latching parts 12 connected to the elastic component 13 change from the clearance state to the latching state, the elastic component 13 is stretched. Under the elastic force of the elastic component 13, both of its connected latching parts 12 return from the latching state to the clearance state.

[0045] Specifically, the elastic component 13 includes at least one elastic element 131. When the elastic component 13 includes one elastic element 131, both ends of the elastic element 131 along its extension direction are respectively connected to two snap-fit ​​portions 12 to connect the two snap-fit ​​portions 12. When the elastic component 13 includes multiple elastic elements 131, the extension directions of the multiple elastic elements 131 are all parallel, and both ends of each elastic element 131 along its extension direction are respectively connected to two snap-fit ​​portions 12 to connect the two snap-fit ​​portions 12.

[0049] For example, Figures 2 to 5 Two snap-fit ​​parts 12 are provided on the connecting body 11, and these two snap-fit ​​parts 12 must be a snap-fit ​​unit.

[0050] In this application, the connecting component 10 also includes a pushing part 14; the pushing part 14 passes through the first mounting hole 911; during the process of the pushing part 14 passing through the first mounting hole 911, the pushing part 14 pushes the locking part 12 from the avoidance state to the locking state; after the pushing part 14 passes through the first mounting hole 911, the pushing part 14 is fixed relative to the hole wall of the first mounting hole 911.

[0051] Optionally, during the process of the pushing part 14 penetrating the first mounting hole 911, the pushing part 14 pushes all the latching parts 12 from the avoidance state to the latching state. During the process of the pushing part 14 moving out of the first mounting hole 911, the force exerted by the pushing part 14 on all the latching parts 12 gradually disappears, and under the elastic force of the elastic component 13, all the latching parts 12 return from the latching state to the avoidance state.

[0052] During the specific installation process, the connecting body 11 is first inserted through the second mounting member 92 and then through the first mounting hole 911 of the first mounting member 91. During this insertion process, all the snap-fit ​​parts 12 are in a clearance state to facilitate the insertion of the connecting body 11. Then, the pushing part 14 is inserted into the first mounting hole 911 so that all the snap-fit ​​parts 12 change from a clearance state to a snap-fit ​​state. Finally, the pushing part 14 is fixed relative to the hole wall of the first mounting hole 911.

[0053] In this application, the pushing part 14 has a pushing surface 140; from the direction in which the pushing part 14 passes through the first mounting hole 911, the pushing surface 140 gradually approaches the center line of the first mounting hole 911; during the process of the pushing part 14 passing through the first mounting hole 911, the pushing surface 140 contacts the locking part 12 to push the locking part 12 from the avoidance state to the locking state.

[0054] Optionally, during the process of the pushing part 14 penetrating the first mounting hole 911, the pushing surface 140 contacts all the snap-fit ​​parts 12, so as to push all the snap-fit ​​parts 12 from the avoidance state to the snap-fit ​​state.

[0058] Specifically, a first fixing groove is provided on the outer wall of the first pushing section 141, and a second fixing groove is provided on the hole wall of the first mounting hole 911. When the pushing part 14 passes into the first mounting hole 911, the first fixing groove and the second fixing groove are joined together to form a fixing groove.

Even if the pushing part 14 and the first mounting part 91 are relatively fixed, all the snap-fit ​​parts 12 are kept in a snap-fit ​​state, thereby ensuring the stable connection of the first mounting part 91 and the second mounting part 92.

[0059] It should be noted that by setting the stop member 16 in the first fixing groove and the second fixing groove, the pushing part 14 and the hole wall of the first mounting hole 911 are relatively fixed in the circumferential direction of the first mounting hole 911; by making the stop member 16 interference fit with the groove wall of the first fixing groove and interference fit with the groove wall of the second fixing groove, the pushing part 14 and the hole wall of the first mounting hole 911 are relatively fixed in the penetration direction of the pushing part 14; thereby ensuring the relative fixation of the pushing part 14 and the first mounting member 91.

[0072] Specifically, the first end of the through hole 112 extends to the first end face of the connecting body 11; the pushing part 14 passes through the first end of the through hole 112 and enters the through hole 112 to push the locking part 12 from the avoidance state to the locking state; that is, the second pushing section 142 passes through the first end of the through hole 112 and enters the through hole 112 so that the pushing surface 140 pushes the locking part 12 from the avoidance state to the locking state.

[0073] Specifically, the elastic component 13 is located inside the through hole 112.

[0074] Optionally, the pushing surface 140 is adapted to fit the wall of the through hole 112 so that the pushing surface 140 is in close contact with the wall of the through hole 112; that is, when the pushing part 14 is inserted into the through hole 112, the pushing surface 140 is in close contact with the wall of the through hole 112, and the pushing surface 140 slides along the wall of the through hole 112. After the pushing part 14 is inserted into the through hole 112, along the insertion direction of the pushing part 14, the pushing surface 140 includes a first surface segment and a second surface segment connected to each other. The first surface segment is in close contact with the wall of the through hole 112, and the second surface segment is in contact with the locking part 12.

The connector 34 is connected to the second mounting member 92 and the connector 34 is connected to the sliding part 33.

[0107] Specifically, the first assembly part 21 is provided with at least one connecting hole 211; each connecting component 10 corresponds to one connecting hole 211. When there are multiple connecting components 10, the first assembly part 21 is provided with multiple connecting holes 211, and the multiple connecting components 10 are provided in a one-to-one correspondence with the multiple connecting holes 211. The connecting body 11 is used to be fixedly inserted into the connecting hole 211; the axial direction of the connecting hole 211 is the same as the axial direction of the first mounting hole 911 and the axial direction of the second mounting hole 921.

[0108] Specifically, along the distribution direction of the first mounting member 91 and the second mounting member 92, both ends of the connecting hole 211 penetrate the first assembly part 21.

[0109] Optionally, the first assembly part 21 is a plate-shaped structure; both ends of the connecting hole 211 penetrate through the two plate surfaces of the first assembly part 21.

[0111] Specifically, the connecting body 11 and the first assembly part 21 are threaded together; the connecting hole 211 has an internal thread on its wall.

[0113] Specifically, a portion of the slide cylinder 311 is fixedly mounted on the first mounting member 91, and another portion is fixedly mounted on the first assembly part 21; the first assembly part 21 is fixedly connected to the first mounting member 91 through the slide cylinder 311, so as to improve the support strength of the receiving component 20, that is, to improve the support strength of the receiving member 23.

[0114] Specifically, the first assembly part 21 is provided with a second fixing hole 212; a part of the slide cylinder 311 is fixedly disposed in the first fixing hole 914, and the other part is fixedly disposed in the second fixing hole 212; the axial direction of the first fixing hole 914 is the same as that of the second fixing hole 212.

[0115] Specifically, the receiving component 20 includes a second assembly part 22, and the first assembly part 21 and the receiving part 23 are both fixedly connected to the second assembly part 22, so that the receiving part 23 is fixedly connected to the first assembly part 21 through the second assembly part 22.

[0120] In this application, the safety component 30 also includes a detection element 35 disposed in the slide rail 31 to detect the position of the sliding part 33 in the slide rail 31, and thereby detect whether the second mounting member 92 is detached or detached from the first mounting member 91.

[0121] Specifically, when the sliding part 33 is in a preset position within the slide rail 31, the second mounting member 92 is well connected to the first mounting member 91, and at this time, the second mounting member 92 does not detach from the first mounting member 91. When the detection member 35 detects that the sliding part 33 deviates from the preset position along the extension direction of the slide rail 31 and moves closer to the second mounting member 92, it determines that the connection between the second mounting member 92 and the first mounting member 91 is loose, and at this time, the second mounting member 92 detaches from the first mounting member 91.

[0122] Optionally, the detection element 35 is a distance sensor.

[0124] This utility model also provides an installation structure, which includes a first mounting member 91, a second mounting member 92, and the aforementioned connecting mechanism. Optionally, the connecting mechanism includes a plurality of connecting components 10.

[0125] This utility model also provides a vibrating screen, which includes the above-described mounting structure.

[0126] Optionally, the first mounting component 91 is a pressure plate, and the second mounting component 92 is a screen front blind plate. Using the connection mechanism of this application, a stable connection between the screen front blind plate and the pressure plate can be ensured, avoiding or reducing the phenomenon that the threaded connection between the connecting body 11 and the screen front blind plate may loosen due to severe vibration of the screen front blind plate, thus causing the screen front blind plate to detach from the pressure plate. Therefore, the connection mechanism of this application can achieve the effect of preventing the screen front blind plate from loosening, solving the problem of the screen front blind plate easily detaching from the pressure plate in existing vibrating screens.

[0127] In practice, when the blind plate in front of the screen suddenly falls off the pressure plate due to an accident, the sliding part 33 abuts against the stop part 32, which can prevent the blind plate in front of the screen from falling further, thereby avoiding the blind plate falling off and interfering with other parts of the vibrating screen, which could cause a more serious accident.

[0128] Specifically, the vibrating screen also includes a control mechanism, and the detection element 35 is electrically connected to the control mechanism. When the detection element 35 detects that the sliding part 33 deviates from the preset position along the extension direction of the slide rail 31 and toward the direction of the second mounting part 92, it indicates that the blind plate in front of the screen has fallen off. The detection element 35 sends a corresponding signal to the control mechanism so that the control mechanism can control the vibrating screen to stop in time for maintenance, thereby avoiding the expansion of accident losses and reducing accident losses.

[0129] Optionally, when the detection element 35 detects that the sliding part 33 slides along the extension direction of the slide rail 31 and moves towards the second mounting part 92 until it abuts against the stop part 32, it indicates that the blind plate in front of the screen has fallen off. The detection element 35 sends a corresponding signal to the control mechanism so that the control mechanism controls the vibrating screen to stop for maintenance.

[0130] Optionally, the control mechanism includes a PLC controller and relays.

[0131] Specifically, when the blind plate in front of the screen falls off the pressure plate, the receiving part 23 can hold the blind plate in front of the screen to support it and prevent more serious accidents.

[0132] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0133] In the connecting mechanism provided by this utility model, the connecting mechanism is used to connect a first mounting member 91 and a second mounting member 92. The first mounting member 91 has a first mounting hole 911, and a slot 912 is provided on the wall of the first mounting hole 911. The connecting mechanism includes at least one connecting component 10, which includes a connecting body 11 and a snap-fit ​​part 12. The connecting body 11 is fixedly inserted into the second mounting member 92 and inserted into the first mounting hole 911 of the first mounting member 91. The snap-fit ​​part 12 is telescopically disposed on the connecting body 11 in a preset direction, so that the snap-fit ​​part 12 has a clearance state located within the connecting body 11 and a snap-fit ​​state at least partially protruding from the connecting body 11. When the snap-fit ​​part 12 is in the snap-fit ​​state, the portion of the snap-fit ​​part 12 protruding from the connecting body 11 is located in the slot 912 of the first mounting member 91, so that the connecting body 11 is snap-fitted and fixed to the first mounting member 91 through the snap-fit ​​part 12.

[0134] The connecting mechanism of this application achieves a secure fastening of the connecting body 11, preventing it from loosening due to the high-frequency vibration of the vibrating screen. This, in turn, avoids or reduces the risk of the blind plate in front of the screen becoming loose. The safety component 30 of this application can monitor the loosening of the blind plate in front of the screen, avoiding or reducing serious consequences such as material mixing, subsequent screen blockage, or even machine damage caused by the loosening of the blind plate in front of the screen, thus improving economic efficiency.
