DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The purpose of the utility model is to provide a blasthole filling machine to solve the problems existing in the prior art. The utility model only requires one person to fill the blasthole, reducing the number of operators, and can automatically fine-tune the position of the discharge port of the filling device, ensuring the filling effect, and improving the level of automation. It is flexible in application and is conducive to improving work efficiency.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] like Figures 1 to 3 As shown, the utility model provides a blasthole plugging machine 100, comprising: a traveling mechanism, the traveling mechanism comprising a vehicle head 1, a vehicle bucket 2 and an electric tailgate 3, the vehicle head 1 being connected to one end of the vehicle bucket 2, the electric tailgate 3 being connected to the other end of the vehicle bucket 2, and the vehicle bucket 2 being used to hold the plugging material;

[0033] The conveying device 4 is arranged in the truck bucket 2 and can convey the filling material in the truck bucket 2 to the end close to the electric tailgate 3;

[0034] A stuffing device is provided outside the electric tailgate 3, is connected to the truck bed 2, and has a feed port provided on one side below the inner bottom wall of the truck bed 2;

[0035] An electric control rod 5, the two ends of which are connected to the truck bed 2 and the stuffing device respectively. The electric control rod 5 can adjust the position of the stuffing device discharge port by extending and retracting along the length direction of the electric control rod 5;

[0036] The camera device 6 is connected to the truck bed 2 and can capture images of the discharge port and blasthole of the stuffing device;

[0037] The central control platform includes a display module 7 and a central control component. The display module 7 and the central control component are both arranged on the front of the vehicle 1. The electric tailgate 3, the conveying device 4, the electric control rod 5, the camera device 6 and the display module 7 are all connected to the central control component. The central control component can control the opening degree of the electric tailgate 3, the central control component can control the conveying device 4 to be opened or closed, and the central control component can control the extension length of the electric control rod 5.

[0038] The utility model drives the stuffing device to move by the walking mechanism, obtains the image of the discharge end and the blast hole of the stuffing device in real time through the camera device 6 and transmits the image information to the central control component and displays it on the display module 7. The driver judges whether the position of the discharge port of the stuffing device and the blast hole is preliminarily aligned by checking the image on the display module 7; after receiving the image information from the camera device 6, the central control component can judge whether the discharge port of the stuffing device and the blast hole are aligned, and control the extension and retraction of the electric control rod 5 to fine-tune the position of the discharge port of the stuffing device until the discharge end of the stuffing device and the blast hole are well aligned; thereafter, the central control component controls the electric tailgate 3 to open, so that a discharge gap is formed between the electric tailgate 3 and the bottom wall of the bucket 2, and the central control component controls the conveying device 4 to open, so as to realize the conveying of the stuffing material to one end of the electric tailgate 3, so that the stuffing material falls into the stuffing device from the discharge gap, and falls into the blast hole from the discharge port of the stuffing device, completing the stuffing of the blast hole. The utility model only requires one person to complete the filling of the blasthole, reducing the number of operators, and can automatically fine-tune the position of the discharge port of the filling device, ensuring the filling effect, improving the level of automation, and facilitating improved work efficiency. At the same time, by adjusting the opening degree of the electric tailgate 3, the flow rate of the filling material can be adjusted to a certain extent. For example, when there is a lot of filling material in the truck bed 2, the opening degree of the electric tailgate 3 can be appropriately reduced to make the discharge gap smaller. When there is less filling material in the truck bed 2, the opening degree of the electric tailgate 3 can be appropriately increased to make the discharge gap larger. The utility model is flexible in application and easy to control.

[0039] It should be noted that the front of the vehicle 1 is movably connected to the truck bed 2, and the electric tailgate 3 and the truck bed 2 can form a rotational connection around a rotation axis. The rotation axis is the axis at the upper end of the electric tailgate 3 and parallel to the width direction of the front of the vehicle 1, so that when the electric tailgate 3 is opened, the filling material can fall from the gap between the electric tailgate 3 and the truck bed 2 into the material receiving component 8.

[0040] In the present invention, the filling device includes a material receiving component 8 and a hose 9. The hose 9 is connected to the discharge port of the material receiving component 8. The feed port of the material receiving component 8 is located on one side below the inner bottom wall of the truck bed 2. The end of the electric control rod 5 away from the truck bed 2 is connected to the hose 9. The electric control rod 5 can bend and deform the hose 9 by extending and contracting along the length of the electric control rod 5 to adjust the position of the discharge port of the hose 9. The deformation characteristics of the hose 9 are used to adjust the discharge port position of the hose 9, resulting in a simple structure and easy adjustment.

[0041] In a preferred embodiment, the electric control lever 5 includes two telescopic rods, positioned on either side of the hose 9 along the width of the truck bed 2, to adjust the position of the hose 9 outlet along the width of the truck bed 2. The position of the hose 9 outlet along the length of the vehicle body is adjusted by the driver observing the relative position of the hose 9 outlet and the blast hole on a display device and moving the traveling mechanism forward and backward. During operation, the driver first aligns the hose 9 outlet with the blast hole along the length of the truck bed 2 by observation, then fine-tunes the relative position of the hose 9 outlet and the blast hole across the width of the truck bed 2 using the electric control lever 5 to achieve alignment across the width of the truck bed 2.

[0042] In the present invention, the filling device further includes an electric switch 10, which is disposed on the filling device and connected to the central control assembly. The filling device has a material discharge channel 11, and the central control assembly can control the opening or closing of the material discharge channel 11 through the electric switch 10. When the discharge port of the filling device is aligned with the muzzle, the central control assembly can control the electric switch 10 to open, and the filling material falls into the muzzle through the material discharge channel 11. When a certain amount of filling material is filled in the muzzle, the central control assembly controls the electric switch 10 to close, the material discharge channel 11 is closed, and the filling stops.

[0043] The present invention also includes a distance measuring device 12, which is connected to the vehicle body 2 and is connected to the central control component by signal. The distance measuring device 12 is used to detect the distance between the filling material in the blasthole and the distance measuring device 12. When the distance between the filling material and the distance measuring device 12 is less than a set value, that is, when a certain amount of filling material is filled in the blasthole, the central control component prompts the driver to stop filling through voice or text.

[0044] The present invention also includes an electric tarpaulin 13, which is connected to the truck bed 2 and to the central control unit. The central control unit can control the opening and folding of the electric tarpaulin 13. When the electric tarpaulin 13 is opened, it can cover the top of the truck bed 2, preventing the filling material in the truck bed 2 from falling over the top of the truck bed 2 when the vehicle travel mechanism moves. It can also provide shade and protect against rain and snow. When the working environment is too hot or it is rainy or snowy, the electric tarpaulin 13 can be opened to protect the filling material.

[0045] In the present invention, the central control assembly includes an electric control rod control button 14 and a control module 15. The electric control rod 5, the camera device 6 and the display module 7 are all connected to the control module 15, and the electric control rod control button 14 is connected to the electric control rod 5. The control module 15 is written with an alignment recognition and correction program. The control module 15 can realize automatic control of the electric control rod 5, and the electric control rod control button 14 can manually control the electric control rod 5. When the central control assembly fails or other reasons, the PVC pipe and the blasthole are not aligned, or the error is too large, the driver operates the electric control rod control button 14 and manually adjusts the electric control rod 5 according to the image on the display module 7, thereby manually adjusting the position of the discharge port of the filling device. It should be noted that the alignment recognition and correction program is a prior art and will not be described in detail here.

[0046] In the present invention, the central control assembly further includes a switch control button 16, which is connected to the electric switch 10. The switch control button 16 can be used to control the opening and closing of the electric switch 10, thereby controlling the opening or closing of the feeding channel 11.

[0047] In the present invention, the central control assembly further includes a tailgate control button 17 , which is connected to the electric tailgate 3 . The tailgate control button 17 can control the opening and closing of the electric tailgate 3 .

[0048] In the present invention, the central control assembly further comprises a conveying control button 18 , which is connected to the conveying device 4 , and can control the opening and closing of the conveying device 4 .

[0049] In the present invention, the central control assembly further includes a tarpaulin control button 19 , which is connected to the electric tarpaulin 13 . The tarpaulin control button 19 can control the electric tarpaulin 13 to open or fold.

[0050] As a preferred embodiment, a switch control button 16 is connected to the control module 15 and sends a signal to the control module 15, which controls the opening or closing of the electric switch 10. A tailgate control button 17 is connected to the control module 15 and sends a signal to the control module 15, which controls the opening or closing of the electric tailgate 3. A conveyor control button 18 is connected to the control module 15 and sends a signal to the control module 15, which controls the opening or closing of the conveyor device 4. A tarpaulin control button 19 is connected to the control module 15 and sends a signal to the control module 15, which controls the opening or folding of the electric tailgate 3.

[0051] In a preferred embodiment, the electric switch 10 is mounted on the hose 9. The electric switch is an electric gate, consisting of a circular telescopic piece. When extended, the piece closes the material discharge channel 11, and when retracted, it opens the material discharge channel 11. The camera 6 is a high-definition camera; the distance measuring device 12 is an infrared distance measuring sensor; the conveyor 4 is a conveyor belt, consisting of a belt and a conveyor pulley; the running mechanism is a truck, with the central control platform mounted inside the cab of the vehicle 1; the electric control lever control button 14 is the operating handle of the electric control lever 5; and the display module 7 is a display screen. The electric tailgate 3 is composed of a symmetrical hexagonal steel plate. The tarpaulin control button 19, the conveyor control button 18, the tailgate control button 17, the switch control button 16, and the electric control lever control button 14 are arranged in order from top to bottom.

[0052] In a preferred embodiment, the filler material is less than 3 cm in diameter to facilitate passage through the electric gate. Considering the relatively large borehole diameters used in large-scale blasting, the diameter of hose 9 is set to approximately 120 mm. The bottom of hose 9 is no more than 150 mm above the ground to prevent tipping of hose 9 due to excessive distance from the ground, which would result in waste of filler material. Hose 9 is a PVC tube.

[0053] The operation process of the blasthole plugging machine 100 provided by the present invention is as follows:

[0054] Drive the blasthole packing machine 100 to the blasting area. The driver observes the display screen and moves the packing machine. When the PVC pipe and the packing hole are displayed on the screen, the driver observes their positions and brakes the vehicle when they are roughly aligned. The central control unit uses the image transmitted by the high-definition camera to identify the position of the PVC pipe and the blasthole. It then controls the electric control lever 5 to fine-tune the PVC pipe, aligning the PVC pipe outlet with the blasthole. Once aligned, the driver presses the tailgate control button 17 and the switch control button 16, followed by the feed control button 18 to begin feeding the packing material into the blasthole. Simultaneously, the infrared rangefinder activates, monitoring the packing height in the blasthole in real time. When the packing height is about to reach the designed height, the central control unit notifies the driver, who then closes the electric switch 10, the electric tailgate 3, and the feed mechanism, completing the packing process. The traveling mechanism then moves to the vicinity of the next blasthole, and the process repeats.

[0055] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
