Description

Technical Field

[0001] This invention relates to the field of unloading tools, and more particularly to an electrically driven unloading tool. Background Technology

[0002] Currently, unloading operations on some KM70 vehicles mainly rely on workers manually operating a "rotary" tool. The doors are opened and closed by rotating the unloading tray. However, the workers continuously turn the crank handle, resulting in high labor intensity and being time-consuming and labor-intensive. The low speed and efficiency of manual operation also affect the overall unloading efficiency. Furthermore, prolonged work can easily lead to worker fatigue and poses a safety risk due to operational errors. Summary of the Invention

[0003] In order to overcome the shortcomings mentioned in the background art, the present invention provides an electrically driven unloading tool.

[0004] An electrically driven unloading tool includes a power tool with a protective housing. A connecting shaft is located inside the protective housing and connected to the output shaft of the power tool. A pressing disc is fixedly connected to the connecting shaft. Symmetrically distributed sliding rods are also fixedly connected to the connecting shaft. A pushing disc is slidably connected to the connecting shaft and is slidably connected to the sliding rods. An inner spline sleeve is fixedly connected to the side wall of the pushing disc via a connecting rod. A bushing is mounted on the protective housing via a bearing. A slot is provided at the end of the bushing. An outer spline key is fixedly connected to the outer surface of the bushing. The inner spline sleeve and the outer spline key are slidably engaged. A clamping assembly for fixing the unloading disc is provided on one side of the power tool.

[0005] To further explain, both the extrusion disc and the push disc are made of magnetic materials, and the opposing sides of the extrusion disc and the push disc are magnetically attracted to each other.

[0006] To further explain, both the extrusion plate and the push plate have two arc-shaped protrusions on their opposing sides, with the bottom ends of the two arc-shaped protrusions adjacent to each other.

[0007] To further explain, the slot is an internal hexagonal slot, which facilitates the installation of other parts.

[0008] To further explain, the key teeth of the inner spline sleeve and the outer spline keyboard are angled.

[0009] Further explanation: the clamping assembly includes a mounting plate disposed on one side of the power tool. A groove is formed in the middle of the mounting plate, and symmetrically distributed sliders are slidably connected in the groove. A bidirectional threaded rod is rotatably connected to the mounting plate, and the bidirectional threaded rod is threadedly connected to the symmetrically distributed sliders. A crank is fixedly connected to the end of the bidirectional threaded rod. A clamping block is fixedly connected to the side wall of the slider. An mounting block is fixedly connected to the side wall of the mounting plate. A groove is formed on the mounting block, and an insert is provided in the groove. The insert engages with the slot.

[0010] To further explain, the symmetrically distributed clamping blocks have V-shaped surfaces facing each other, and rubber pads are bonded to the V-shaped surfaces of the clamping blocks.

[0011] To further explain, the mounting block is slidably connected with insert rods that are circumferentially equidistant, the ends of the insert rods are fixedly connected to limit blocks, and a return spring is fixedly connected between the limit blocks and the mounting block. The outer side of the protective shell is provided with insert holes that are circumferentially equidistant, and the insert rods are slidably located in the insert holes.

[0012] To further explain, the inner ends of the inserts, which are circumferentially equidistant, are all inclined surfaces and face away from the mounting plate.

[0013] The beneficial effects of this invention are as follows: This invention transmits power to the connecting shaft through an electric tool, enabling transmission through the magnetic attraction of the extrusion plate and the push plate. This avoids damage caused by the connecting shaft continuing to directly drive the push plate to rotate when the unloading turntable cannot rotate. Furthermore, the mounting block drives the mounting plate to rotate through the cooperation of the slot and the insert. The rotation of the mounting plate, through the parts on it, enables the turntable to be unloaded to move circumferentially, thereby realizing the opening or closing of the unloading door. This reduces labor intensity and improves unloading efficiency through electric means, while avoiding labor fatigue. Attached Figure Description

Detailed Implementation

[0023] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0024] An electrically driven unloading tool, such as Figures 1-8 As shown, the device includes a power tool 1, a protective housing 2, a connecting shaft 3 inside the protective housing 2, and the connecting shaft 3 connected to the output shaft of the power tool 1. A pressing disc 4 is fixedly connected to the connecting shaft 3, and two symmetrically distributed sliding rods 5 are also fixedly connected to the connecting shaft 3. A pushing disc 6 is slidably connected to the connecting shaft 3, and the pushing disc 6 is in a limited sliding connection with the sliding rods 5. Both the pressing disc 4 and the pushing disc 6 are made of magnetic material, and their opposing sides are magnetically attracted to each other. Each opposing side of the pressing disc 4 and the pushing disc 6 has two... The two curved convex plates are adjacent at their bottom ends. An inner spline sleeve 7 is fixed to the left side wall of the push plate 6 via a connecting rod. A bushing 8 is mounted on the protective shell 2 via a bearing. A slot 9 is provided at the left end of the bushing 8. The slot 9 is an internal hexagonal slot, which is convenient for installing other parts. An outer spline keyboard 10 is fixed to the right side of the outer side of the bushing 8. The inner spline sleeve 7 and the outer spline keyboard 10 are in a limited sliding fit. The key teeth of the inner spline sleeve 7 and the outer spline keyboard 10 are set at an angle. A clamping assembly for fixing the unloading plate is provided on the left side of the power tool 1.

[0025] The clamping assembly includes a mounting plate 11, which is disposed on one side of the power tool 1. A groove 12 is provided in the middle of the mounting plate 11, and two symmetrically distributed sliders 13 are slidably connected in the groove 12. A bidirectional threaded rod 14 is rotatably connected to the mounting plate 11, and the bidirectional threaded rod 14 is threadedly connected to the two sliders 13. A crank handle 15 is fixedly connected to the end of the bidirectional threaded rod 14. A clamping block 16 is fixedly connected to the lower side wall of the slider 13. The two clamping blocks 16 have V-shaped surfaces facing each other, and rubber pads are bonded to the V-shaped surfaces of the clamping blocks 16. A mounting block 17 is fixedly connected to the top of the mounting plate 11. A groove 18 is provided on the mounting block 17, and an insert block 19 is provided in the groove 18. The insert block 19 mates with the slot 9.

[0026] Four circumferentially equidistant insertion rods 20 are slidably connected to the mounting block 17. The inner ends of the four insertion rods 20 are all inclined surfaces facing upwards (e.g., ...). Figure 8 As shown), the end of the insertion rod 20 is fixedly connected to a limiting block 21, and a return spring 22 is fixedly connected between the limiting block 21 and the mounting block 17. The outer side of the protective shell 2 is provided with four circumferentially equidistant insertion holes 23, and the insertion rod 20 slides within the insertion holes 23.

[0027] In use, the operator first places the mounting plate 11 on the turntable where unloading is required. Then, the operator rotates the crank handle 15 clockwise. This clockwise rotation, via the bidirectional threaded rod 14, causes the two sliders 13 to move towards each other. This movement of the sliders 13 moves the clamping blocks 16 on them, clamping and securing the turntable. Next, the operator uses the power tool 1 to gradually insert the protective shell 2 into the groove 18. During this process, the protective shell 2 presses against the inclined surface of the insertion rod 20, causing the insertion rod 20 to move outwards. The return spring 22 then stretches. When the protective shell 2 moves to engage with the insertion hole 23 on it, the return spring 22 forces the insertion rod 20 into the insertion hole 23, completing the installation. While the protective shell 2 is being inserted into the groove 18, the operator starts the power tool 1, which transmits power through the output shaft. The rotation of the connecting shaft 3 (clockwise or counterclockwise, adjustable by the user) drives the extrusion disc 4 and its component slide bar 5 to rotate. The rotation of the extrusion disc 4 causes the arc-shaped protrusion plate on it to press and push the disc 6 to move. The moving disc 6 moves away from the extrusion disc 4 and gradually disengages from the limiting sliding engagement with the slide bar 5. Subsequently, the rotation of the connecting shaft 3 drives the disc 6 to rotate through the magnetic attraction of the extrusion disc 4. During this process, the movement of the connecting rod on the disc 6 enables the inner spline sleeve 7 to drive the outer spline key 10 to rotate at a certain angle. The rotation of the outer spline key 10 enables the bushing 8 to rotate, thus allowing the slot 9 on the bushing 8 to be installed and matched with the insert 19, avoiding the need for workers to adjust the position of the slot 9 and the insert 19. This simplifies the user's operation and prevents damage caused by the connecting shaft 3 continuing to directly drive the disc 6 to rotate when the turntable cannot rotate during unloading.

[0028] After the power tool 1 transmits power to the connecting shaft 3, it enables transmission through the magnetic attraction of the pressing disc 4 and the pushing disc 6. Then, through the cooperation of the slot 9 and the insert block 19, the mounting block 17 drives the mounting plate 11 to rotate. The rotation of the mounting plate 11, through the parts on it, enables the turntable that needs to be unloaded to move circumferentially, thereby enabling the unloading door to be opened or closed. In this way, the labor intensity is reduced by electric means, while improving the unloading efficiency and avoiding labor fatigue.
