Description

Technical Field

[0001] This application relates to the field of stone unloading technology, specifically to an adjustable unloading device that can adapt to the tilt angle of the stone. Background Technology

[0002] In the production of slate, the stone is cut into square blocks at the mine, and then the stone is cut into slices. However, the bottom of the slate is still attached to the stone, so there is a later step to remove the slate from the stone. This step mainly involves workers using an electric pick to drill along the bottom corner of the slate, then vibrating the slate to remove it, and finally transporting it to the storage area.

[0003] There are two main methods for unloading stone slabs: manual unloading and sawing unloading. Manual unloading is entirely done by hand, which is time-consuming, labor-intensive, inefficient, and has high labor costs. Furthermore, it generates a lot of dust and poses certain safety risks to workers. While sawing unloading equipment can unload stone slabs, the stone itself may have angular deviations during the cutting process or due to external factors. This leads to waste of stone during sawing and increases the amount of subsequent processing required, thus increasing costs. Utility Model Content

[0004] This application aims to solve the problems existing in the background art and provides an adjustable unloading device that can adapt to the tilt angle of the stone, and adopts the following technical solution.

[0013] Furthermore, the bending angle of the mounting ramp is greater than 90° and less than 180°.

[0014] Furthermore, the buffer compensation mechanism also includes a front buffer mechanism, which includes a movable plate.

[0019] The left and right translation mechanism includes a slide rail, a slider mounted on the slide rail, a drive motor, and a lead screw connected to the drive motor.

[0020] The forward and backward translation mechanism includes a slide rail, a slider mounted on the slide rail, a drive motor, and a lead screw connected to the drive motor.

[0021] Furthermore, the impact head is an electric pick, a pneumatic pick, an impact drill, or an electric drill.

[0022] The beneficial effects of this application are:

[0038] Reference Figure 1-6 This application provides an adjustable unloading device, comprising:

[0039] Supporting framework;

[0040] Vertical moving mechanism 12, which is mounted on the support frame, is used to move vertically up and down along the support frame;

[0041] A left-right translation mechanism 13 is mounted on the up-down vertical translation mechanism 12 and is used to move horizontally left and right along the up-down vertical translation mechanism 12.

[0042] A forward and backward translation mechanism 11, installed at the bottom of the support frame, is used to drive the stone to move horizontally back and forth along the support frame; and

[0043] A buffer compensation mechanism is installed on the left and right translation mechanism 13. The mechanism includes a horizontal mounting plate 2203, which is horizontally mounted on the mechanism. A mounting inclined plate 2101 is rotatably connected to the first end of the horizontal mounting plate 2203. A tension spring 2201 connects the first end of the mounting inclined plate 2101 and the second end of the horizontal mounting plate 2203, causing the mounting inclined plate 2101 to form a certain angle with the horizontal mounting plate 2203. The mounting inclined plate 2101 itself has a certain angle of bending. An impact head 2001 is slidably mounted on the second end of the mounting inclined plate 2101. A drive cylinder 2004 for moving the impact head 2001 is also installed on the second end of the mounting inclined plate 2101.

[0044] The front-to-back translation mechanism 11 drives the stone to move horizontally back and forth to the impact position, the up-and-down vertical movement mechanism 12 cooperates with the front-to-back translation mechanism 11 to drive the impact head 2001 to the bottom corner of the stone, and the mounting inclined plate 2101 compensates for the tilt error of the stone slab after cutting.

[0045] It is understood that this application also includes a control mechanism, which is capable of controlling the movement of each moving mechanism and the action of each driving component to complete the unloading of the stone slab. The control mechanism can be a commonly used control device in the art, and has functions such as receiving signals, outputting signals, and manual programming control.

[0046] Specifically, during operation, this application drives the stone to move towards the impact head 2001 via the front-to-back translation mechanism 11, ensuring the impact head 2001 is flush against the inclined stone slab wall. Then, the vertical movement mechanism 12 drives the impact head 2001 downwards along the inclined wall. During this downward movement, the rotational connection between the mounting inclined plate 2101 and the horizontal mounting plate 2203, along with the tension spring 2201, allows the impact head 2001 to slide downwards along the inclined stone slab wall to the bottom corner. Finally, driven by the left-to-right translation mechanism 13, the impact head 2001 impacts and unloads the stone along the bottom corner. In actual cutting, due to various reasons, such as the stone slab's own weight after cutting, the cut stone slab may tilt. In this case, the buffer compensation mechanism provided in this application can compensate for the tilt error of the stone slab, making impact unloading more convenient.

[0047] Reference Figure 4 The mounting plate 2203 is rotatably connected to the horizontal mounting plate 2203 via a central rotating mechanism 21. Specifically, the central rotating mechanism 21 comprises a bearing fixing seat 2102, an optical shaft, and a support seat 2103. The central rotating mechanism 21 is mounted on the horizontal mounting plate 2203 via the support seat 2103, and the bearing fixing seat 2102 is connected to the mounting inclined plate 2101, thereby driving the mechanism on the mounting inclined plate 2101 to rotate. A rear buffer compensation mechanism 23, consisting of a tension spring 2201 and a tension spring mounting piece 2202, is installed at the lower part of the mounting inclined plate 2101 to provide a slanted displacement movement for the buffer compensation mechanism. One end of the tension spring 2201 is located near the end of the horizontal mounting plate 2203 via the tension spring mounting piece 2202, and the other end of the tension spring 2201 is located near the end of the upper end of the mounting inclined plate 2101.

[0048] It is understood that the angle between the horizontal mounting plate 2203 and the mounting inclined plate is greater than 0° and less than 90°.

[0049] Specifically, the horizontal mounting plate 2203 and the mounting inclined plate 2101 have a certain angle, which makes the mounting inclined plate 2101 form a certain angle with the horizontal plane, thereby making the impact head 2001 form a certain angle with the horizontal plane, so that the impact head 2001 can be better aligned with the bottom corner of the stone slab.

[0050] It is understood that the bending angle of the mounting ramp 2101 is greater than 90° and less than 180°.

[0051] Specifically, the mounting ramp 2101 is bent at a certain angle so that the buffer compensation mechanism can have a larger sliding amount and a smaller displacement at the end of the mounting ramp 2101, while also having a larger rotation angle.

[0052] Reference Figure 4 and 5 The buffer compensation mechanism further includes a front buffer mechanism 20, which includes a movable plate 2006. The movable plate 2006 is mounted on the second end of the mounting inclined plate 2101 via a first guide rail slider mechanism 2009. A first buffer spring 2008 connected to the movable plate 2006 is mounted on the guide rail slider mechanism. The impact head 2001 is mounted on the movable plate 2006.

[0053] Specifically, a front buffer mechanism 20 is installed at the lower part of the mounting ramp 2101. The front buffer mechanism 20 comprises a fixed base 2002, a movable plate 2006, a first buffer spring 2008, a drive cylinder 2004, a push plate 2005, a first proximity switch 2010, and a first guide rail slider mechanism 2009. The impact head 2001 is mounted on the movable plate 2006 via the fixed base 2002; the movable plate 2006 is mounted on the first guide rail slider mechanism 2009, and the first buffer spring 2008 is mounted on the slide rail of the first guide rail slider mechanism 2009. When the first guide rail slider mechanism 2009 moves, it pushes the first buffer spring 2008 to form a buffer amount. This mechanism enables the impact head 2001 to have a linear displacement movement along the ramp direction.

[0054] Reference Figure 4 and 5 It is understood that a first proximity switch 2010 is provided at the second end of the mounting inclined plate 2101, and the moving plate 2006 can drive the impact head 2001 to contact the first proximity switch 2010.

[0055] The first proximity switch 2010 can give a signal to the control mechanism and start the impact head 2001 to perform an impact.

[0056] Reference Figure 4 and 6 It is understood that the second end of the mounting inclined plate 2101 is also provided with two boundary measuring mechanisms, which are symmetrically arranged on both sides of the impact head 2001.

[0057] The boundary determination mechanism includes a mounting frame 301, on which a second guide rail slider mechanism is mounted. The second guide rail slider mechanism includes a linear guide rail 303 and a linear slider 312. A guide wheel 310 is mounted on the second guide rail slider mechanism, and a second buffer spring 311 connected to the guide wheel 310 is mounted on the second guide rail slider mechanism. A second proximity switch 306 is mounted on the mounting frame 301, and the guide wheel 310 can contact the second proximity switch 306 when it moves on the second guide rail slider mechanism 303.

[0058] Specifically, the boundary measurement mechanism mainly includes a guide wheel 310, a guide wheel mounting block 309, a guide shaft 308, a fixing clamp 307, a mounting frame 301, a blocking block 302, a second buffer spring 311, a second proximity switch 306, and a second guide rail slider mechanism 303. The guide wheel 310, guide wheel mounting block 309, and guide shaft 308 are connected by pins, allowing the guide wheel 310 to roll along the stone slab wall. A square groove is cut into the guide shaft 308, and when the two fixing blocks 307 are closed, there is a square hole in the middle that is the same size as the guide shaft 308. The guide shaft 308 is mounted on the second guide rail slider mechanism 303 via the fixing blocks 307, thus preventing the fixing blocks 307 from sliding on the guide shaft 308 when the stone slab boundary measuring device is subjected to a large force. Two second buffer springs 311 are installed on the linear guide rail 303. The linear slider 312 pushes against the second buffer springs 311 when sliding on the linear guide rail 303, and the compression of the second buffer springs 311 ensures the forward and backward movement of the mechanism. The second guide rail slider mechanism 303 is mounted on the mounting frame 301 by placing it on the blocking block 302. The mounting frame 301 is bolted to the moving plate 2006, thus fixing it to the buffer compensation module. The mounting frame 301 is equipped with a second proximity switch 306. In the boundary measuring mechanism, when the second buffer spring 311 is compressed to the calibrated displacement, it will push the fixed clamp 307 close to the second proximity switch 306, thereby triggering the second proximity switch 306 to send a signal to the external control mechanism.

[0059] Specifically, when the forward and backward translation mechanism 11 drives the stone to move towards the impact head 2001, the guide wheel 310 of the boundary measuring mechanism first contacts the stone slab. The stone slab pushes the guide wheel 310 to move, causing the fixed clamp 307 to contact the second proximity switch 306. When both second proximity switches 306 are in contact with the stone, they send a signal to the control mechanism to confirm that the impact head 2001 has completely entered the stone slab area. At this time, the vertical movement mechanism 12 and the horizontal translation mechanism 13 control the impact head 2001 to move to the bottom corner of the stone slab. Then, the horizontal translation mechanism 13 controls the impact head 2001 to move to the left or right. When the impact head 2001 approaches the edge of the stone slab, one boundary measuring mechanism will exit the stone slab boundary before the impact head 2001. At this time, the corresponding boundary measuring mechanism will reset under the action of the second buffer spring 311, and the corresponding fixed clamp 307 will disengage from the corresponding second proximity switch 306. A signal will be sent to the control mechanism to confirm that the impact head 2001 has reached the stone slab boundary. When the impact head 2001 reaches the boundary of the stone slab, the forward and backward translation mechanism 11 drives the stone slab to continue moving and pushes the impact head 2001 and the moving plate 2006 to move (the guide wheel 310 of the boundary measuring mechanism moves simultaneously, and the fixed clamping block 307 remains in contact with the second proximity switch 306). When the moving plate 2006 contacts the first proximity switch 2010, a signal is triggered and sent to the control mechanism. The control mechanism controls the drive cylinder 2004 to drive the push plate 2005 to move. The push plate 2005 triggers the switch of the impact head 2001, and the impact head 2001 is activated to perform the impact. It is understood that the drive cylinder 2004 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. In this application, a corresponding air source, liquid source, or power source can be set in a suitable position.

[0060] It is understood that the vertical movement mechanism 12 includes a slide rail, a slider mounted on the slide rail, a drive motor, and a lead screw connected to the drive motor;

[0061] The left and right translation mechanism 13 includes a slide rail, a slider mounted on the slide rail, a drive motor, and a lead screw connected to the drive motor.

[0062] The forward and backward translation mechanism includes a slide rail, a slider mounted on the slide rail, a drive motor, and a lead screw connected to the drive motor.

[0063] Furthermore, the impact head 2001 is an electric pick, a pneumatic pick, an impact drill, or an electric drill.

[0064] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this application should be included within the protection scope of this application.
