[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Reference Figure 1-9 The embodiment of the present invention provides a zircon-titanium ore shaking table sorting device, comprising a main body 1 and a bed surface 2, wherein the main body 1 is provided with a guide frame 3, a rotating ring 4 and a lifting mechanism: one end of the guide frame 3 is hinged on the main body 1, and the bed surface 2 is slidably connected to the guide frame 3; the rotating ring 4 is fixed to the end of the guide frame 3 away from the main body 1, and the hinge point of the main body 1 and the guide frame 3 is located on the central axis of the rotating ring 4; the lifting mechanism comprises a movable block 5 rotatably connected to the rotating ring 4 and a lifting component for driving the movable block 5 to rise and fall.

[0035] Specifically, the main body 1 is a frame structure, the bed surface 2 is arranged on the main body 1, and a plurality of troughs are generally arranged on the bed surface 2. When the device is running, vibration and water flow can be used to make ores of different specific gravities and particle sizes fall into different troughs, thereby separating the zircon-titanium ore into concentrate and tailings. The above are all existing technologies and will not be repeated here. The innovation of the embodiment of the present invention lies in that a guide frame 3 is hinged on the main body 1, and the guide frame 3 is a frame structure formed by fixing a plurality of rods to each other. The guide frame 3 is provided with two round rods 6 along its axial direction, and two sliders 7 are fixed at the bottom of the bed surface 2, and the two sliders 7 are respectively slidably connected to the two round rods 6, so that the bed surface 2 can reciprocate (vibrate) along the axial direction of the guide frame 3; the main body 1 and the guide frame 3 can be hinged in a universal joint hinge manner, and preferably, the main body 1 and the guide frame 3 are hinged by a ball joint; such a configuration enables one end of the guide frame 3 to rotate freely on the main body 1 to drive the bed surface 2 to adjust the longitudinal and transverse slopes; the lifting component can use the cylinder structure in the prior art, and its two ends are respectively hinged on the main body 1 and the movable block 5 to drive the movable block 5 to lift and lower, and when the movable block 5 is driven to lift and lower by the lifting component, the movable block 5 and the rotating ring 4 are rotated around the hinge point of the guide frame 3 and the main body 1 to adjust the guide frame 3. The longitudinal slope of the frame 3 and the bed surface 2 can be adjusted; the hinge point of the main body 1 and the guide frame 3 is located on the central axis of the guide frame 3 and the central axis of the rotating ring 4 at the same time, so that when the rotating ring 4 rotates on the movable block 5, it can drive the guide frame 3 to rotate around the hinge point of the main body 1 and the guide frame 3 to adjust the lateral slope of the bed surface 2; the advantage is that one end of the guide frame 3 is hinged to the main body 1. At this time, whether the rotating ring 4 is lifted or rotated, it can drive the guide frame 3 to rotate around the hinge point of the main body 1 and the guide frame 3, so as to adjust the slope of the bed surface 2, wherein the lifting component changes the height of the rotating ring 4 to adjust the longitudinal slope of the bed surface 2, and the rotating ring 4 rotates on the movable block 5 to adjust the lateral slope of the bed surface 2, so that the central axis of the rotating ring 4 and the guide frame 3 are movable on the same vertical plane, and then a vibration structure is set on the same vertical plane (the output end of the vibration structure is connected to the bed surface 2 for transmission) to drive the bed surface 2 to vibrate on the guide frame 3 to sort zircon-titanium ore.

[0036] A zircon-titanium ore shaking table sorting device provided in an embodiment of the present invention hinges one end of a guide frame 3 to a main body 1, and then the height of a rotating ring 4 can be changed through a lifting assembly to adjust the longitudinal slope of a bed surface 2, and then the rotating ring 4 can be driven to rotate on a movable block 5 to adjust the transverse slope of the bed surface 2, thereby allowing the central axis of the rotating ring 4 to adjust its position on the same vertical plane, making it convenient to set a vibration structure on the same vertical plane to drive the bed surface 2 to vibrate, thereby reducing the complexity of the slope adjustment of the device.

[0037] In another embodiment provided by the present invention, the lifting assembly includes a lifting frame 8 movably connected to the movable block 5 and a hydraulic cylinder 9 for driving the lifting frame 8 to move up and down. The movable block 5 is configured with two movable columns 10, and the lifting frame 8 is configured with two slide slots 11 adapted to the movable columns 10. Specifically, the overall structure of the lifting frame 8 is a square structure with a square space inside. The movable block 5 is located inside the square structure of the lifting frame 8, and the outer wall of the movable block 5 fits the inner wall of the lifting frame 8 so that the movable block 5 can slide in the square structure of the lifting frame 8; two slide grooves 11 are respectively constructed on opposite sides of the lifting frame 8, and the two movable columns 10 on both sides of the movable block 5 are respectively slidably connected in the two slide grooves 11, so that the movable block 5 can slide on the lifting frame 8 through the two movable columns 10, and at the same time, the movable block 5 can rotate in the slide groove 11 of the lifting frame 8 through the movable columns 10 (rotate around the axial direction of the movable columns 10); the hydraulic cylinder 9 can be directly fixed vertically on the main body 1, and the other end of the hydraulic cylinder 9 can be directly fixed to the lifting plate, so that the lifting plate is driven to rise and fall vertically on the main body 1 through the hydraulic cylinder 9 (this is the prior art, not shown in the figure); optionally, two groups of hydraulic cylinders 9 are symmetrically hinged on both sides of the lifting plate, and the other ends of the two groups of hydraulic cylinders 9 are hinged on the main body 1, and the two groups of hydraulic The angles between the cylinders 9 and the main body 1 are the same. When the two groups of hydraulic cylinders 9 are synchronously extended or shortened, the lifting plate can be driven to vertically lift and lower on the main body 1 through the two groups of hydraulic cylinders 9; in this way, when the hydraulic cylinders 9 are running, the lifting plate, the movable block 5 and the rotating ring 4 can be driven to lift and lower on the main body 1, wherein the lifting plate is vertically lifted and lowered on the main body 1, and the movable block 5 and the rotating ring 4 are both rotated around the hinge point of the guide frame 3 and the main body 1, that is, the lifting trajectory of the movable block 5 is an arc, so that when the movable block 5 is lifted and lowered with the lifting plate, the movable column 10 will slide in the corresponding slide groove 11 to adapt to the change in the height of the movable block 5. After the height of the lifting plate, the movable block 5 and the rotating ring 4 is determined, the longitudinal slope of the bed 2 is determined accordingly; then the rotating ring 4 is driven to rotate on the movable block 5 to drive the bed 2 to rotate around the central axis of the guide frame 3 and the rotating ring 4 to adjust the transverse slope of the bed 2, thereby completing the adjustment of the angle of the bed 2, which is convenient for sorting ores of different specific gravities and particle sizes.

[0038] Preferably, the movable block 5 is constructed with an arc groove 12, the rotating ring 4 is rotatably connected in the arc groove 12, and the movable block 5 is screwed with a limit bolt 13. Specifically, the arc groove 12 is constructed in the movable block 5, and the center of the arc groove 12 is on the central axis of the rotating ring 4, and a part of the rotating ring 4 is inserted in the arc groove 12, so that the rotating ring 4 can rotate on the movable block 5 through the arc groove 12 (rotate around the center of the arc groove 12); the limit bolt 13 is screwed on one side of the movable block 5 and extends into the arc groove 12, and the relative position of the rotating ring 4 and the movable block 5 can be limited by the limit bolt 13. When the rotating ring 4 rotates on the movable block 5, the limit bolt 13 always corresponds to the rotating ring 4. After the angle of the rotating ring 4 is determined, tightening the limit bolt 13 can limit the relative position of the rotating ring 4 and the movable block 5, thereby determining the transverse slope of the bed surface 2.

[0039] Furthermore, a connecting shaft 14 is fixed on the bed surface 2, and the connecting shaft 14 is slidably connected to the rotating ring 4, and the connecting shaft 14 is arranged along the central axis of the rotating ring 4. Specifically, a sleeve 15 is arranged inside the rotating ring 4, and the sleeve 15 is arranged along the central axis of the rotating ring 4. The outer wall of the sleeve 15 and the inner wall of the rotating ring 4 are fixed by a connecting rod 16 (that is, the two ends of the connecting rod 16 are respectively fixed on the sleeve 15 and the rotating ring 4), the sleeve 15 is hollow inside and the connecting shaft 14 is penetrated in the sleeve 15, so that the connecting shaft 14 can slide in the sleeve 15 along the central axis of the rotating ring 4, thereby driving the bed surface 2 to slide on the guide frame 3, so that the vibration structure and the connecting shaft 14 can be connected in transmission.

[0040] Furthermore, it also includes a driving mechanism (similar to the above-mentioned vibration structure) for driving the connecting shaft 14 and the bed surface 2 to reciprocate along the guide frame 3. Specifically, the driving mechanism can select a linear reciprocating driving structure in the prior art, such as a cylinder structure; preferably, the driving mechanism includes a chassis 17 fixed to the main body 1, one end of the chassis 17 is slidably connected to a driving shaft 18, an extension portion 19 is fixed to the driving shaft 18, a connecting groove 20 is configured on the extension portion 19, a movable groove is configured in the connecting shaft 14, a sliding rod 21 is slidably connected in the movable groove, and a connecting column 22 adapted to the connecting groove 20 is configured on the sliding rod 21.The chassis 17 is located on the side of the lifting plate away from the bed surface 2, and the drive shaft 18 is located on the side of the chassis 17 close to the lifting plate. The drive shaft 18 is arranged along the length direction of the main body 1. A reciprocating drive structure is arranged in the chassis 17 to drive the drive shaft 18 to reciprocate (the reciprocating drive structure can be a combination of an eccentric wheel and a connecting rod in the prior art, and then the eccentric wheel is driven to rotate by a reduction motor, thereby driving the drive shaft 18 to reciprocate on the chassis 17. The reciprocating drive structure is a prior art. The eccentric wheel and the connecting rod structure inside the chassis 17 are not shown in the figure and are not described here). There are two extensions 19 vertically structured on the drive shaft 18, and both extensions 19 are structured with connecting grooves 20, and the connecting grooves 20 passes through the extension part 19; the slide bar 21 and the movable groove are both arranged along the axial direction of the connecting shaft 14, the slide bar 21 is constructed as a non-rotating body, the slide bar 21 and the movable groove are adapted to each other, so that the slide bar 21 can slide in the movable groove but cannot rotate in the movable groove; the slide bar 21 extends between the two extension parts 19, and the two opposite sides of the slide bar 21 are constructed with connecting columns 22, and the two connecting columns 22 are respectively located in the two connecting grooves 20; the connecting groove 20 has a certain length, so that the connecting column 22 can move relatively in the connecting groove 20; a bolt structure can be set between the slide bar 21 and the connecting shaft 14 to limit the relative position of the slide bar 21 and the connecting shaft 14; between the guide frame 3 and the bed surface 2 When the longitudinal slope is 0 (i.e., horizontal setting), the connecting shaft 14 is parallel to the driving shaft 18, and the angle between the slide bar 21 and the extension portion 19 is 90 degrees. When the driving shaft 18 reciprocates on the chassis 17, the inner wall of the connecting groove 20 can force the connecting column 22 to reciprocate with the driving shaft 18, thereby driving the connecting shaft 14 and the bed surface 2 to reciprocate (i.e., vibrate) on the guide frame 3, and during the reciprocating movement of the bed surface 2, the position of the connecting column 22 in the connecting groove 20 remains unchanged; when it is necessary to adjust the longitudinal slope of the bed surface 2 and the guide frame 3, first release the restriction on the slide bar 21 and the connecting shaft 14, and then drive the rotating ring 4 to deflect upward through the lifting mechanism. At this time, the angle between the slide bar 21 and the connecting shaft 14 changes, so that the slide bar 21 and the extension part 19 are no longer vertical. At the same time, the overall length of the slide bar 21 and the connecting shaft 14 needs to be extended appropriately so that the connecting column 22 remains in the connecting groove 20. After the longitudinal slope of the bed surface 2 is adjusted, the relative position of the slide bar 21 and the connecting shaft 14 can be restricted again by bolts. Subsequently, when the drive shaft 18 reciprocates on the chassis 17, the inner wall of the connecting groove 20 can force the connecting column 22 to reciprocate with the drive shaft 18. During the process, the connecting column 22 will reciprocate relatively in the connecting groove 20 to adapt to the change in the height of the connecting column 22 when the bed surface 2 reciprocates.

[0041] The advantage of such a configuration is that, in this embodiment, the hinge point of the main body 1 and the guide frame 3, the connecting shaft 14 and the driving shaft 18 are located in the same plane. When the longitudinal slope of the bed surface 2 is adjusted, the connecting shaft 14, the driving shaft 18 and the extension 19 are also maintained in the same vertical plane. Correspondingly, the connecting shaft 14, the slide bar 21, the extension 19 and the driving shaft 18 are also maintained in the same vertical plane, that is, the longitudinal slope of the bed surface 2 can be adjusted by the connecting column 22 and the connecting groove 20, while the driving shaft 18 is maintained to drive the connecting shaft 14 to drive the bed surface 2. It reciprocates on the guide frame 3, and then uses vibration to sort the zirconium-titanium ore; in this way, the angle of the bed surface 2 can be adapted without changing the position of the driving structure, and the complexity of the slope adjustment step of the device can be reduced as much as possible (in the prior art, when adjusting the slope of the bed surface 2, it is necessary to adjust the position of the driving structure to adapt to the vibration of the driving bed surface 2. In each embodiment of the present invention, the hinge points of the main body 1 and the guide frame 3, the connecting shaft 14 and the driving shaft 18 can be placed in the same plane to adapt to the adjustment of the slope of the bed surface 2 without changing the position of the driving structure).

[0042] As an alternative to the fixed connection between the connecting shaft 14 and the bed surface 2, preferably, the connecting shaft 14 and the bed surface 2 are rotatably connected, and the two opposite sides of the slide bar 21 are both configured with a flat surface 23, and the two connecting columns 22 are respectively configured on the two flat surfaces 23. Specifically, in the above embodiment, the slide bar 21 is configured as a non-rotating body so that the two connecting rods 16 can be stably located in the two connecting grooves 20, but when the transverse slope of the bed surface 2 is adjusted, the angles of the slide bar 21 and the connecting column 22 will change, which will cause the connecting column 22 and the connecting groove 20 to interfere with each other, so the connecting shaft 14 and the bed surface 2 are rotatably connected and the flat surface 23 is provided. In this embodiment, the connecting shaft 14 and the bed surface 2 are rotationally connected, so that the connecting shaft 14 can drive the bed surface 2 to reciprocate on the guide frame 3 while rotating relative to the bed surface 2; the rotation connection point of the connecting shaft 14 and the bed surface 2 is located on the central axis of the connecting shaft 14, so that when the transverse slope of the bed surface 2 is adjusted, the connecting shaft 14 and the slide bar 21 can rotate relative to the bed surface 2, the guide frame 3, the rotating ring 4 and the sleeve 15; the two flat portions 23 on the slide bar 21 are respectively fitted with the two extension portions 19, and when the connecting column 22 is located inside the connecting groove 20, the slide bar 21 and the connecting shaft 14 can be restricted by the two extension portions 19 (so that the connecting shaft 14 can only adjust the longitudinal slope with the bed surface 2, but cannot adjust the transverse slope with the bed surface 2), so as to prevent the connecting shaft 14 from rotating with the bed surface 2. The advantage of such a configuration is that when the transverse slope of the bed surface 2 is adjusted, structures such as the rotating ring 4 and the sleeve 15 rotate with the bed surface 2, while structures such as the connecting shaft 14 and the sliding rod 21 are restricted by the extension portion 19, thereby minimizing interference between the connecting column 22 and the connecting groove 20 when the transverse slope of the bed surface 2 is adjusted.

[0043] A return spring 24 is provided between the guide frame 3 and the bed surface 2. Specifically, the return spring 24 is sleeved on the round rod 6 of the guide frame 3, one end of which is fixed on the slider 7 at the bottom of the bed surface 2, and the other end is fixed on the outer wall of the round rod 6, so that the return spring 24 applies elastic force to the bed surface 2; when the bed surface 2 is driven to reciprocate on the guide frame 3 by the driving mechanism, the return spring 24 can repeatedly store and release elastic potential energy during the reciprocating movement of the bed surface 2, so as to buffer the reciprocating motion of the bed surface 2 (the spring provided on the rocking bed to buffer the vibration of the bed surface 2 is a prior art, which will not be described in detail here).

[0044] In another embodiment provided by the present invention, as an alternative scheme for limiting the relative position between the sliding rod 21 and the connecting shaft 14 by the bolt structure mentioned above, preferably, a driving ring 25 is rotatably connected in the movable groove, and the driving ring 25 is sleeved on the sliding rod 21. A through groove 26 is constructed on the driving ring 25, and a limiting plate 27 is slidably connected in the through groove 26. The driving ring 25 is provided with a first elastic member 28 for forcing the limiting plate 27 to move away from the sliding rod 21. An operating rod 29 is passed through the sliding rod 21, and an L-shaped rod 30 is fixed on the operating rod 29, and the end of the L-shaped rod 30 is constructed with a wedge-shaped surface. Specifically, in this embodiment, the movable groove has a certain movable space inside, the driving ring 25 is rotatably connected to the inner wall of the movable groove, and the central axis of the driving ring 25 coincides with the central axis of the sliding rod 21, and can be inserted into the driving ring 25 when the sliding rod 21 extends into the movable groove; the driving ring 25 is configured with a through groove 26 on both opposite sides, and the through groove 26 is configured along the radial direction of the driving ring 25, and the two through grooves 26 are slidably connected to the limit plates 27, and the two limit plates 27 are located on the outside of the sliding rod 21, and the limit plates 27 are configured in an arc shape; the first elastic member 28 can select an elastic sheet structure in the prior art, one end of which is fixed on the driving ring 25, and the other end is fixed on the outer wall of the limit plate 27, so as to force the limit plate 27 away from the sliding rod 21 through the first elastic member 28; in order to improve the sliding stability of the limit plate 27, the two driving rings 25 are rotatably connected in the movable groove, so that the limit plate 27 can be slidably connected to the two driving rings 2 at the same time 5, and correspondingly, two groups of first elastic members 28 can also be provided; the interior of the slide bar 21 is hollow for passing the operating rod 29, so that the operating rod 29 can slide and rotate in the slide bar 21, and both ends of the operating rod 29 are exposed from the slide bar 21, and an L-shaped rod 30 is fixed at one end of the operating rod 29 located in the movable groove, and a handle 31 is fixed at the other end of the operating rod 29. One end of the L-shaped rod 30 is vertically fixed to the operating rod 29, and the other end is arranged parallel to the operating rod 29. A wedge-shaped surface is constructed at the end of the L-shaped rod 30 away from the operating rod 29. The L-shaped rod 30 can be inserted into the through-slot 26 to force the limit plate 27 to overcome the elastic force of the first elastic member 28 and contact the outer wall of the slide bar 21 (the limit plate 27 can also be constructed with a wedge-shaped surface, so that the L-shaped rod 30 and the wedge-shaped surfaces of the limit plate 27 contact each other, thereby forcing the limit plate 27 to approach the slide bar 21). During the process, the positions of the L-shaped rod 30 and the first elastic member 28 are staggered with each other (such as Figure 6As shown); when the device is used, the L-shaped rod 30 is inserted into the through groove 26 to force the limit plate 27 to contact the outer wall of the slide bar 21 through the wedge surface, and then the side of the L-shaped rod 30 close to the operating rod 29 can contact the limit plate 27, so that the relative position of the slide bar 21 and the connecting shaft 14 is limited by the L-shaped rod 30 and the limit plate 27, so that the driving shaft 18 can drive the bed surface 2 to reciprocate on the guide frame 3 through the slide bar 21 and the connecting shaft 14; when adjusting the longitudinal slope of the bed surface 2, first press the handle 31 to make the operating rod 29 extend into the movable groove, so that The L-shaped rod 30 is driven to move out of the through groove 26, thereby releasing the restriction of the L-shaped rod 30 on the limit plate 27, so that the limit plate 27 can be moved away from the slide bar 21 under the action of the first elastic member 28, thereby releasing the restriction on the relative position of the connecting shaft 14 and the slide bar 21, so that when the longitudinal slope of the bed surface 2 is adjusted, the slide bar 21 can be extended in the movable groove to adapt to the position of the connecting column 22 in the connecting groove 20, until the longitudinal slope of the bed surface 2 is determined, and the handle 31 is stretched outward to insert the L-shaped rod 30 into the through groove 26 again, so that the relative position of the connecting shaft 14 and the slide bar 21 can be restricted again. The advantage is that in this embodiment, the relative position of the connecting shaft 14 and the slide bar 21 can be locked and unlocked by stretching and pressing the handle 31, which is more convenient than the limiting method of the bolt structure.

[0045] Furthermore, the inner wall of the limit plate 27 is configured with an internal thread 32, and the outer wall of the slide bar 21 is configured with an external thread 33. Specifically, the internal thread 32 and the external thread 33 are adapted to each other, and after the limit plate 27 contacts the outer wall of the slide bar 21, the internal thread 32 and the external thread 33 are engaged with each other, so that a threaded connection is formed between the slide bar 21 and the drive ring 25, at which time the drive ring 25 and the limit plate 27 can be driven to rotate by the operating rod 29 and the L-shaped rod 30 (the L-shaped rod 30 drives one drive ring 25 to rotate, one drive ring 25 drives two limit plates 27 to rotate, and the two limit plates 27 drive another drive ring 25 to rotate), and the slide bar 21 and the movable groove are non-rotating structures adapted to each other, and if the handle 31 drives the operating rod 29 and the drive ring 25 to rotate, the threaded structure can drive the slide bar 21 to slide in the movable groove. The advantages of such a configuration are that, firstly, the friction between the limit plate 27 and the slide bar 21 can be increased by the threaded structure, thereby further strengthening the limiting effect of the limit plate 27 on the slide bar 21; secondly, when the relative position of the slide bar 21 and the connecting shaft 14 is limited by the limit plate 27, the connecting shaft 14 and the bed surface 2 can be driven to reciprocate on the guide frame 3 by the driving shaft 18. At this time, without adjusting other structures, the overall length of the connecting shaft 14 and the slide bar 21 can be adjusted by turning the handle 31. At this time, the driving mechanism is in In the stopped state, the position of the drive shaft 18 is restricted by the structure inside the motor box 17 and does not change, while the positions of the bed surface 2 and the connecting shaft 14 on the guide frame 3 can be adjusted to allow the bed surface 2 to further squeeze or release the reset spring 24, so that the elastic force on the bed surface 2 can be adjusted (fine-tuned) to further adapt to the vibration process of the bed surface 2; thirdly, no matter where the slide bar 21 is located in the movable groove, the L-shaped rod 30 can be disengaged from the through groove 26 when the handle 31 is directly pressed, thereby releasing the restriction of the limit plate 27 on the slide bar 21.

[0046] It should be noted that after the L-shaped rod 30 is disengaged from the through-groove 26, the rotation of the operating rod 29 will cause the L-shaped rod 30 and the through-groove 26 to be misaligned. At this time, the operating rod 29 can also be rotated to allow the L-shaped rod 30 to be inserted into the corresponding through-groove 26. For this purpose, multiple groups of L-shaped rods 30 and limiting plates 27 structures can be provided. For example, if two groups of L-shaped rods 30 are provided on the operating rod 29, the L-shaped rod 30 can be inserted into the corresponding through-groove 26 by rotating the operating rod 29 at most by 90 degrees. When the handle 31 is stretched to allow the L-shaped rod 30 to be inserted into the through-groove 26, the limiting plate 27 can be squeezed through the wedge surface to allow the inner screw 30 to be inserted into the through-groove 26. The groove 32 and the external thread 33 are engaged, and the positions of the internal thread 32 and the external thread 33 may be misaligned, resulting in the limit plate 27 being unable to fit onto the outer wall of the slide bar 21, and the L-shaped rod 30 being unable to be fully inserted into the through groove 26. In this case, the handle 31 can be slightly rotated to adjust the position of the drive ring 25 and the limit plate 27 until the internal thread 32 and the external thread 33 correspond to each other, and the handle 31 can be stretched again to make the limit plate 27 fit onto the outer wall of the slide bar 21, thereby limiting the position of the slide bar 21, and then the elastic force of the return spring 24 acting on the bed surface 2 can be fine-tuned.

[0047] Furthermore, the connecting shaft 14 is provided with an engaging groove connected to the movable groove, a friction block 34 is slidably connected in the engaging groove, a second elastic member 35 is provided in the movable groove for forcing the friction block 34 to fit into the engaging groove, and a wedge-shaped surface is provided on one side of the movable groove. Specifically, during the reciprocating movement of the connecting shaft 14 along the sleeve 15, the friction block 34 always corresponds to the inner wall of the sleeve 15; the second elastic member 35 can adopt a spring structure in the prior art, one end of which is fixed on the inner wall of the movable groove, and the other end is fixed on the friction block 34, so as to force the friction block 34 to fit into the engaging groove through the second elastic member 35; when the handle 31 is pressed to make the operating rod 29 extend into the movable groove, the end of the operating rod 29 can contact the wedge-shaped surface on the friction block 34, so as to force The friction block 34 overcomes the elastic force of the second elastic member 35 and extends out of the fitting groove (the second elastic member 35 and the operating rod 29 are staggered in the radial direction of the connecting shaft 14, that is, when the operating rod 29 abuts against the friction block 34, the operating rod 29 will not interfere with the second elastic member 35), so that the friction block 34 abuts against the inner wall of the sleeve 15, thereby limiting the relative position of the sleeve 15 and the connecting shaft 14; in the above embodiment, when the longitudinal slope of the bed surface 2 is adjusted, the connecting shaft 14 and the sliding rod The restriction between 21 is released, so that the overall length of the connecting shaft 14 and the sliding rod 21 can be extended to adapt to the relative position of the connecting column 22 and the connecting groove 20. At this time, the relative position between the connecting shaft 14 and the sliding rod 21 is not restricted, and the relative position between the connecting shaft 14 and the sleeve 15 is also not restricted (that is, the relative position between the bed surface 2 and the guide frame 3 is not restricted). This will cause the bed surface 2 to be able to move freely on the guide frame 3 (especially under the action of the reset spring 24), which is easy to affect the reciprocating travel range of the bed surface 2 on the guide frame 3; for this purpose, a friction block 34 structure is provided. When the handle 31 is pressed, the friction block 34 is squeezed by the end of the operating rod 29 so that the friction block 34 contacts the inner wall of the sleeve 15, thereby limiting the relative position of the connecting shaft 14 and the sleeve 15 (that is, limiting the relative position of the bed surface 2 and the guide frame 3), and trying to avoid the relative position of the bed surface 2 and the guide frame 3 changing when the longitudinal slope of the bed surface 2 is adjusted.

[0048] Preferably, a stopper 36 is constructed on the L-shaped rod 30. When the L-shaped rod 30 is inserted into the through-slot 26, the stopper 36 can interfere with the outer wall of the drive ring 25, thereby limiting the L-shaped rod 30 from being completely inserted into the through-slot 26. The effect of such a configuration is that if the L-shaped rod 30 is completely inserted into the through-slot 26, the L-shaped rod 30 will interfere with the end of the slide bar 21, so that the slide bar 21 cannot be further retracted into the movable groove when the operating rod 29 rotates. For this purpose, a stopper 36 structure is provided to limit the position of the L-shaped rod 30 without affecting the operation of the L-shaped rod 30 and the drive ring 25, so that when the operating rod 29 rotates, it can drive the slide bar 21 to extend from or retract into the movable groove, thereby fine-tuning the elastic force exerted on the bed surface 2.

[0049] In summary, in the embodiment of the present invention, the bed surface 2 can be driven to vibrate on the guide frame 3 by the driving shaft 18, and at the same time, the reset spring 24 can force the bed surface 2 to approach the driving shaft 18. When in use, the longitudinal slope of the bed surface 2 can be adjusted by the lifting mechanism, and the transverse slope of the bed surface 2 can be adjusted by the rotating ring 4. When adjusting the longitudinal slope, first press the handle 31 to first limit the relative position between the bed surface 2 and the guide frame 3, and then release the restriction on the relative position between the connecting shaft 14 and the slide bar 21, and then adjust the longitudinal slope of the bed surface 2 to make the connecting column 22 move in the connecting groove 20. After the longitudinal slope of the bed surface 2 is adjusted, stretch the handle 31 to limit the relative position of the connecting shaft 14 and the slide bar 21 again, so that the driving shaft 18 can continue to drive the bed surface 2 to vibrate on the guide frame 3.

[0050] In another embodiment provided by the present invention, as a parallel embodiment of the above-mentioned internal thread 32 and external thread 33 structure, preferably, a limiting surface 37 is constructed at one end of the operating rod 29 away from the handle 31, and when the L-shaped rod 30 is located at the top and (or) the bottom of the operating rod 29, the friction block 34 is located on one side of the movable groove and is parallel to the limiting surface 37. At this time, if the operating rod 29 is extended into the movable groove, the wedge surface on the friction block 34 can be abutted by the limiting surface 37 to force the friction block 34 away from the movable groove, until the friction block 34 abuts against the inner wall of the sleeve 15, and the friction block 34 is located on one side of the movable groove and fits with the limiting surface 37. Then, continuing to extend the operating rod 29 into the movable groove can drive the L-shaped rod 30 to move out of the through groove 26, so that the relative position of the bed surface 2 and the guide frame 3 can be first limited in the process of pressing the handle 31. , and then release the position restriction between the connecting shaft 14 and the sliding bar 21. On the contrary, when the handle 31 is stretched, the relative position of the connecting shaft 14 and the sliding bar 21 is restricted while limiting the relative position of the bed surface 2 and the guide frame 3, and then the restriction on the relative position of the bed surface 2 and the guide frame 3 is released, so as to avoid the relative position of the bed surface 2 and the guide frame 3 from being offset when the longitudinal slope of the bed surface 2 is adjusted; at the same time, by setting the limiting surface 37, the angle of the operating rod 29 can be avoided from being offset, and the situation that the L-shaped rod 30 cannot be inserted into the through groove 26 when the operating rod 29 is reset can be avoided as much as possible, and when the limiting surface 37 and the friction block 34 are separated, the L-shaped rod 30 has been inserted into the corresponding through groove 26. At this time, the operating rod 29 can be rotated without being restricted by the friction block 34, so that the overall length of the sliding bar 21 and the connecting shaft 14 can be adjusted.
