[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example 1

[0033] like Figures 1 to 11 As shown:

[0034] The prior art in this embodiment has the following problems: The inventors have found the following defects in the prior art: 1. The device uses a flashlight as a light source when working at night, but when workers place the shovel in a place with less light, there will be insufficient lighting and the shovel cannot be found, resulting in the loss of the shovel; 2. The device has a single purpose when carrying out mining operations and cannot meet the needs of complex and ever-changing mining sites; 3. When the device is not in use, it needs to be leaned against a vertical surface to stand the shovel upright. Without a vertical surface to lean against, it can only be laid down on the ground. The ground at mining sites is often muddy due to rainwater and construction water, which will cause the shovel to be covered with mud, bringing trouble to the user for subsequent cleaning and maintenance of the shovel;

[0035] Therefore, the inventor provides an open-pit mining shovel for mining engineering, including a device body and a lighting flashlight 1, with the lighting flashlight 1 located on the front side of the device body; the device body also includes a controllable shovel handle 2, a multi-functional shovel head 3, and an auxiliary lighting device 4, with the multi-functional shovel head 3 located below the controllable shovel handle 2 and the auxiliary lighting device 4 located on the outside of the multi-functional shovel handle.

[0036] Using the above scheme, when using the shovel, the multi-functional shovel head 3 can be pulled up by the controllable shovel handle 2 to switch to normal use mode. At this time, the device provides the normal shovel function. The auxiliary lighting device 4 can be equipped with a flashlight 1 to provide illumination and can also provide power to the flashlight 1 by connecting a charging cable. The auxiliary lighting device 4 will automatically charge during the day and can be turned on at night to provide auxiliary lighting. When it is necessary to place the shovel, the controllable shovel handle 2 can be pressed down to adjust to the shovel placement mode. At this time, the multi-functional shovel head 3 changes to a hoe shape, so that the shovel can be placed stably on the ground without support. When it is necessary to break rocks, the controllable shovel handle 2 can be pressed down to switch the multi-functional shovel head 3 to the pickaxe mode. At this time, the device can be used to perform some rock breaking operations, or it can be put away to save space. Example 2

[0037] like Figures 1 to 11 As shown:

[0038] Furthermore, the controllable shovel handle 2 also includes a control handle 5, a small sleeve 6, a large sleeve 7, a fixing mechanism 8, and an adjusting mechanism 9. The control handle 5 is located above the small sleeve 6, the large sleeve 7 is slidably sleeved on the outside of the small sleeve 6, the fixing mechanism 8 is located inside the control handle 5 and the small sleeve 6, and the adjusting mechanism 9 is located inside the large sleeve 7.

[0039] Furthermore, a slider 10 that is slidably connected to the large sleeve 7 is provided on the outer side of the small sleeve 6;

[0040] Furthermore, the control handle 5 also includes a button 11, a spring a12, a steel wire 13, a limiting block 14, a spring b15, and a limiting hole 16. The button 11 is slidably disposed on the inner side above the control handle 5. The spring a12 is disposed between the button 11 and the inner wall of the control handle 5. The limiting block 14 is slidably disposed on the left and right sides of the small sleeve 6. The spring b15 is disposed between the limiting block 14 and the small sleeve 6. The limiting hole 16 is disposed on the inner side of the large sleeve 7 on the left and right sides and matches the front end of the limiting block 14. The steel wire 13 is connected between the upper part of the button 11 and the limiting block 14.

[0041] Furthermore, the adjustment mechanism 9 also includes an adjustment block 17, a slide groove 18, a limiting groove 19, and a spring c20. The adjustment block 17 is located at the bottom of the small sleeve 6, the slide groove 18 is located on the inner side of the bottom of the large sleeve 7 and is slidably connected to the protrusion on the adjustment block 17, the limiting groove 19 is located on the side of the slide groove 18, and the spring c20 is located below the adjustment block 17.

[0042] Furthermore, a slot 21 is provided above the end of the limiting slot 19;

[0043] When the shovel is in normal use mode, the protrusion on the adjusting block 17 is pushed upward by the spring c20 and locked in the slot 21 of the uppermost limiting groove 19. The spring c20 and the slot 21 lock the protrusion of the adjusting block 17 to prevent the adjusting block 17 from sliding during use. When it is necessary to switch modes, the worker presses the button 11 on the control handle 5. The button 11 presses down the spring a12, which drives the steel wire 13 to pull back upward. The pull back of the steel wire 13 drives the end limiting block 14 to squeeze the spring b15 and retract it from the limiting hole 16, thereby releasing the fixing effect of the control handle 5. At the same time, the small sleeve 6 is pressed down inside the large sleeve 7 by the control handle 5, so that the adjusting block 17 can be released from the slot 21 and the fixing is released. Then, the control handle 5 is rotated to move the adjusting block 17 into the limiting groove. The adjusting block 17 slides horizontally out of the limiting groove 19 and into the vertical sliding groove 18. The slider 10 on the outside of the small sleeve 6 can provide stable support in the large sleeve 7 when the device slides and switches. Then, continue to press down to make the adjusting block 17 move to the side of the limiting groove 19 of the next mode. Rotate the control handle 5 horizontally again to make the adjusting block 17 enter the slot 21 and fix it. Release the button 11 on the control handle 5 to make the limiting block 14 re-insert into the corresponding limiting hole 16 to complete the fixation of the device. During this process, the multi-functional shovel head 3 makes corresponding changes in linkage to complete the conversion between the normal use mode, placement mode and pick mode of the device, which meets the equipment needs of workers for complex use in mining sites and improves the applicability of the device. Example 3

[0044] like Figures 1 to 11 As shown:

[0045] Furthermore, the multi-functional shovel head 3 also includes a stone crushing cone 22, a gear 23, a shovel head 24, and a multi-functional foot rod 25. The stone crushing cone 22 is located below the small sleeve 6 and is slidably sleeved inside the large sleeve 7. The gear 23 is located on the rear side of the stone crushing cone 22 and meshes with the tooth groove behind the stone crushing cone 22. The shovel head 24 is located below the gear 23 and is coaxially rotatably connected to the gear 23. The multi-functional foot rod 25 is located on the rear side of the bottom of the large sleeve 7.

[0046] Furthermore, the multi-functional foot lever 25 also includes a pickaxe head 26 on the left and a hammer head 27 on the right;

[0047] When the worker uses the controllable shovel handle 2 to adjust the device's mode, the crushing cone 22 extends or retracts accordingly, simultaneously driving the gear 23 to rotate and allowing the shovel head 24 to rotate. When the crushing cone 22 retracts and the shovel head 24 extends, the device is in normal mode, functioning as a shovel. The multi-functional foot lever 25 provides effortless support when the worker is shoveling stones. When the crushing cone 22 is partially extended, the shovel rotates 90 degrees, allowing the bottom of the shovel to serve as a support surface for placing the device. The front end of the crushing cone 22 can also be inserted into the ground for support. In this placement mode, the shovel handle is prevented from being contaminated by ground mud after the shovel is laid down, extending the device's lifespan and reducing the worker's maintenance burden. When the crushing cone 22 is fully extended, the device is in pickaxe mode. The shovel rotates 90 degrees again and retracts to fit against the multi-functional foot lever 25. At this time, the bottom of the crushing cone 22, along with the picks 26 and hammers 27 at both ends of the multi-functional foot lever 25, can be used to crush smaller stones, meeting the worker's equipment needs for complex mining site conditions. Example 4

[0048] like Figures 1 to 11 As shown:

[0049] Furthermore, the auxiliary lighting device 4 also includes a solar panel 28, a rotating base 29, a fixed base 30, a photosensitive sensor, a controller, a battery 31, and an auxiliary lighting lamp 32. The solar panel 28 is respectively located on the left and right sides of the upper end of the large sleeve 7. The rotating base 29 is located on the front side of the upper end of the large sleeve 7. The fixed base 30 is located on the front side of the rotating base 29. The battery 31 is located on the rear side of the upper end of the large sleeve 7. The controller is located at the bottom of the battery 31. The photosensitive sensor is located on the left side of the controller. The auxiliary lighting lamp 32 is respectively located above the battery 31 and above the left and right sides of the multi-functional step bar 25. The battery 31 is electrically connected to the solar panel 28, the photosensitive sensor, the controller, and the auxiliary lighting lamp 32.

[0050] Furthermore, a charging port for charging the flashlight 1 is provided above the battery 31;

[0051] During the day, a photosensitive sensor (not shown in the figure) detects sunlight and controls the solar panel 31 (not shown in the figure) to charge the battery 31 via a controller (not shown in the figure). When working at night, if the photosensitive sensor detects insufficient light, the controller turns on the power of the battery 31 to turn on the auxiliary light 32. The auxiliary light 32 can be an LED light, so that workers can still find the position of the shovel by using the auxiliary light 32 in the case of insufficient lighting, preventing the shovel from being lost. At the same time, the flashlight 1 can be fixed to the fixed base 30 with bolts, and the angle can be adjusted by rotating the base. When the flashlight 1 is low on power, it can also be temporarily powered by the charging port of the battery 31 (not shown in the figure), which improves the reliability of the device.

[0052] In summary, the device can automatically charge during the day via the auxiliary lighting device 4, and charge the flashlight 1 when using the device at night. Furthermore, the auxiliary lighting device 4, located on the outside of the multi-functional shovel handle, provides illumination to indicate the shovel's position, preventing loss due to insufficient lighting. The operable shovel handle 2 allows adjustment of the multi-functional shovel head 3's state, switching between normal use, shovel placement, and pickaxe modes, meeting the needs of workers in complex mining situations and improving the device's applicability. The multi-functional shovel head 3 can be switched to shovel placement mode via the operable shovel handle 2, standing the shovel upright and preventing the handle from being contaminated by ground mud after the shovel is laid down, extending the device's lifespan and reducing the maintenance burden on workers.

[0053] The working principle of this utility model:

[0054] When using the shovel, the multi-functional shovel head 3 is pulled up by the controllable shovel handle 2 to switch to the normal use mode. When the shovel is in the normal use mode, the protrusion on the adjusting block 17 is pushed upward by the spring c20 and locked in the slot 21 of the uppermost limiting groove 19. The spring c20 and the slot 21 lock the protrusion of the adjusting block 17 to prevent the adjusting block 17 from sliding during use. When the stone crushing cone 22 retracts and the shovel head 24 extends, the device is in the normal mode to use the shovel function.

[0055] When the shovel needs to be placed, the worker presses button 11 on control handle 5. Button 11 presses down spring a12, causing steel wire 13 to pull upward. The pull of steel wire 13 causes the end limit block 14 to compress spring b15 and retract from the limit hole 16, thereby releasing the fixing effect of control handle 5. At the same time, the control handle 5 presses the small sleeve 6 down inside the large sleeve 7, allowing the adjusting block 17 to disengage from the slot 21 and be released from fixation. Then, rotating control handle 5 causes the adjusting block 17 to slide laterally in the limit groove 19, sliding the adjusting block 17 out of the limit groove 19 and into the vertical slide groove 18. The slider 10 on the outside of the small sleeve 6 provides stable support in the large sleeve 7 when the device slides and switches. Then, the worker continues to press down to move the adjusting block 17 into the limit groove of the next mode. 19. Turn the control handle 5 horizontally again to make the adjusting block 17 enter the slot 21 and fix it. Release the button 11 on the control handle 5 so that the limiting block 14 is reinserted into the corresponding limiting hole 16 to complete the fixing of the device. The crushing cone 22 extends as the mode is adjusted. The shovel rotates 90 degrees so that the bottom of the shovel can be used as a support plane to place the device. The front end of the crushing cone 22 can also be inserted into the ground to provide support, preventing the shovel handle from being contaminated by the ground mud after the shovel is laid down. This extends the service life of the device and reduces the maintenance pressure on the workers. At this time, the device is in the placement mode to prevent the shovel handle from being contaminated by the ground mud after the shovel is laid down. This extends the service life of the device and reduces the maintenance pressure on the workers.

[0056] When it is necessary to break rocks, continue to press down the controllable shovel handle 2 to switch the multi-functional shovel head 3 to the pick mode. Continue to press down the control handle 5 in the above way to adjust the device to the pick mode. The shovel will rotate 90 degrees again and retract to fit the multi-functional foot rod 25. At this time, the bottom of the rock crushing cone 22 and the pick heads 26 and hammer heads 27 at the left and right ends of the multi-functional foot rod 25 can be used to crush some smaller rocks. It can also be used as a retracted state to save the placement space of the device and meet the equipment needs of workers for complex use in mining sites, thus improving the applicability of the device.

[0057] During the day, a photosensitive sensor (not shown in the figure) detects sunlight and controls the solar panel 31 (not shown in the figure) to charge the battery 31 via a controller (not shown in the figure). When working at night, if the photosensitive sensor detects insufficient light, the controller turns on the power of the battery 31 to turn on the auxiliary light 32. The auxiliary light 32 can be an LED light, so that workers can still find the position of the shovel by using the auxiliary light 32 in case of insufficient lighting, preventing the shovel from being lost. At the same time, the flashlight 1 can be fixed to the fixed base 30 with bolts, and the angle can be adjusted by rotating the base. When the flashlight 1 is low on power, the charging port of the battery 31 (not shown in the figure) can be used to temporarily power the flashlight 1, improving the reliability of the device.

[0058] This concludes the description of the working principle of the device.
