[0040] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention will be described in more detail below with reference to the accompanying drawings of preferred embodiments of the present invention. Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other unless there is any conflict.

[0041] like Figure 1 、 Figure 2 As shown, an embodiment of the present invention provides a loading alignment device for a bucket wheel excavator, including a bucket wheel excavator, the bucket wheel excavator including a bucket wheel excavator body 1 and a feed hopper mechanism 2, the feed hopper mechanism 2 is movably arranged on the bucket wheel excavator body 1, and the feed hopper mechanism 2 includes a discharge port 221; a limiting mechanism is arranged on the bucket wheel excavator body 1, the limiting mechanism includes a limiting channel and a limiting portion, the limiting channel is used to limit the driving path of the mining truck 100, and the limiting portion is used to limit the parking position of the mining truck 100 so that the bucket of the mining truck 100 is aligned with the discharge port 221.

[0042] The bucket wheel excavator loading alignment device provided by an embodiment of the present invention provides a limiting mechanism on the bucket wheel excavator body 1, and the limiting mechanism includes a limiting channel and a limiting portion. When the mining truck 100 needs to enter the bucket wheel excavator body 1, the limiting channel can limit the driving path of the mining truck 100, so that the mining truck 100 can enter the bucket wheel excavator body 1 along the limiting channel. Moreover, the mining truck 100 can stop under the limiting action of the limiting portion, and align the bucket of the mining truck 100 with the discharge port 221 of the feed hopper mechanism 2, thereby realizing rapid alignment of the mining truck 100 and the bucket wheel excavator. During the alignment process, there is no need for manual communication, the operation is more convenient, manpower is saved, and the loading efficiency is improved.

[0043] Because the feed hopper mechanism 2 is movably mounted on the bucket wheel excavator body 1, once the mining truck 100 is aligned with the bucket wheel excavator, the feed hopper mechanism 2 can be controlled to move relative to the bucket wheel excavator body 1. This allows the feed hopper mechanism 2 to change its unloading position within the bucket of the mining truck 100, thereby improving the uniformity of material loading and preventing accumulation of material in a single location in the bucket. Furthermore, this uniform loading process eliminates the need to coordinate the movement of the mining truck 100, further improving loading efficiency.

[0044] In some embodiments, see Figure 1 and Figure 2 The limiting mechanism may include two guide plate assemblies 3, which are telescopically arranged on both sides of the bucket wheel excavator body 1; the two guide plate assemblies 3 are used to extend to the bottom of the bucket wheel excavator body 1 to form a limiting channel; or, the two guide plate assemblies 3 are used to retract to the bucket wheel excavator body 1 to cancel the limiting channel.

[0045] After the bucket wheel excavator is moved and loading is required, the two guide plate assemblies 3 can be controlled to extend to the bottom of the bucket wheel excavator body 1, so that the two guide plate assemblies 3 form a limiting channel, and the mining truck 100 can travel between the two guide plate assemblies 3, thereby limiting the travel path of the mining truck 100. When loading is completed and the mining truck 100 drives out of the bucket wheel excavator, the two guide plate assemblies 3 can be controlled to retract.

[0046] Among them, the two guide plate assemblies 3 are retractable, and are extended when a limiting channel needs to be formed when loading the mining truck 100 to ensure that the mining truck 100 is aligned with the loading of the bucket wheel excavator, and are retracted at the end of loading to avoid the guide plate assembly 3 affecting the operation of the bucket wheel excavator, thereby ensuring the normal operation of the bucket wheel excavator.

[0047] It can be understood that there are many ways to extend and retract the two guide plate assemblies 3. For example, the guide plate assembly 3 can be rotatably connected to the side of the bucket wheel excavator body 1, and the rotation direction can be consistent with the length direction or width direction of the bucket wheel excavator. When the guide plate assembly 3 rotates to the bottom of the bucket wheel excavator body 1, it extends to form a limiting channel, and when the guide plate assembly 3 rotates in the opposite direction to the bucket wheel excavator body 1, it retracts.

[0048] In some embodiments, see Figure 1 The guide plate assembly 3 may include a telescopic member 31 and a guide plate 32. The fixed end of the telescopic member 31 is connected to the bucket wheel excavator body 1, and the telescopic end of the telescopic member 31 is connected to the guide plate 32. The length direction of the guide plate 32 is consistent with the driving path of the mining truck 100; the telescopic member 31 is used to drive the guide plate 32 to extend to the bottom of the bucket wheel excavator body 1 to form a limiting channel between the two guide plates 32, or the telescopic member 31 is used to drive the guide plate 32 to retract to the bucket wheel excavator body 1 to cancel the limiting channel.

[0049] Among them, the number of telescopic parts 31 and guide plates 32 can be two respectively, and the two telescopic parts 31 are arranged at intervals along the length direction of the bucket wheel excavator body 1, and each telescopic part 31 is connected to the corresponding guide plate 32. The telescopic part 31 can be an electric telescopic rod, and the telescopic direction of the electric telescopic rod can be vertical. When loading is required, the two electric telescopic rods can be controlled to extend to drive the two guide plates 32 to extend to the bottom of the bucket wheel excavator body 1 to form a limiting channel, and the mining truck 100 can travel between the two guide plates 32, thereby realizing the restriction of the driving path of the mining truck 100. When loading is completed, after the mining truck 100 drives out of the bucket wheel excavator, the two electric telescopic rods can be controlled to retract and drive the two guide plates 32 to retract to cancel the limiting channel.

[0050] Specifically, when the electric telescopic rod is extended, the guide plate 32 may or may not be in contact with the ground, as long as a limiting channel can be formed between the two guide plates 32 to limit the travel path of the mining truck 100 .

[0051] In some embodiments, the bucket wheel excavator loading alignment device may further include a direction detection component, which is disposed on the bucket wheel excavator body 1 and is used to detect the mining truck 100 entering or exiting the bucket wheel excavator body 1 and generate a corresponding first electrical signal.

[0052] By setting up a direction detection component, the direction detection component can detect whether the mining truck 100 is currently entering or exiting the bucket wheel excavator body 1, that is, detect the current driving state of the mining truck 100, and generate a first electrical signal corresponding to the driving state and feed it back to the control room 8 for easy control.

[0053] In some embodiments, see Figure 1 The direction detection component may include at least two infrared sensors 4, and the at least two infrared sensors 4 are arranged in sequence along the extension direction of the limiting channel.

[0054] When the mining truck 100 enters the bucket wheel excavator body 1, the infrared sensor 4 located at the outer end of the limiting channel is triggered first, and the infrared sensor 4 located at the inner end of the limiting channel is triggered later. Correspondingly, when the mining truck 100 exits the bucket wheel excavator body 1, the triggering order of the at least two infrared sensors 4 is reversed. Therefore, the current driving state of the mining truck 100 can be determined by the triggering order of the at least two infrared sensors 4, facilitating operation.

[0055] In some embodiments, see Figure 1 、 Figure 3 and Figure 4 The limiting part may include a limiting plate 5, one end of which is connected to the bucket wheel excavator body 1, and the limiting plate 5 is used to abut against the mining truck 100 to stop the mining truck 100; when the limiting plate 5 abuts against the mining truck 100, the bucket of the mining truck 100 is aligned with the discharge port 221.

[0056] When the mining truck 100 is driving into the bucket wheel excavator body along the limiting channel, the mining truck 100 can stop when it abuts against the limiting plate 5. At this time, the truck bucket is aligned with the discharge port 221 of the bucket wheel excavator body 1, thereby conveniently and accurately realizing the alignment of the mining truck 100 and the bucket wheel excavator.

[0057] It should be noted that the bucket wheel excavator loading alignment device provided in the embodiment of the present invention realizes accurate alignment of the mining truck 100 and the bucket wheel excavator by setting a limiting mechanism, that is, structurally improving the bucket wheel excavator, making the operation more convenient, the use more reliable, and the cost saving.

[0058] In some embodiments, see Figure 1 、 Figure 3 and Figure 4 The limiting portion may further include a buffer member 6 , the other end of the limiting plate 5 is detachably connected to the buffer member 6 , and the limiting plate 5 is used to abut against the mining truck 100 through the buffer member 6 .

[0059] By providing the buffer member 6, the buffer member 6 can buffer the impact force between the mining truck 100 and the limiting plate 5, thereby avoiding damage to the mining truck 100 and the limiting plate 5. Specifically, the buffer member 6 can be a flexible plate such as a rubber plate.

[0060] In addition, since the buffer 6 abuts against the mining truck 100, the buffer 6 is a wearing part and requires regular maintenance and replacement. In the above embodiment, the buffer 6 and the limit plate 5 are detachably connected, which can facilitate the maintenance and replacement of the buffer 6. There are various ways to detachably connect the buffer 6 and the limit plate 5, such as screw connection, snap connection, etc.

[0061] In some embodiments, see Figure 1 and Figure 6 The feed hopper mechanism 2 may include a feed hopper 21 and a discharge pipe 22. The feed hopper 21 is movably arranged on the bucket wheel excavator body 1, and the moving direction of the feed hopper 21 is consistent with the extension direction of the limiting channel; one end of the discharge pipe 22 is connected to the feed hopper 21, and the other end of the discharge pipe 22 is provided with a discharge port 221, and the discharge pipe 22 extends toward the bucket of the mining truck 100.

[0062] During the loading process, the movement of the feed hopper 21 can be controlled so that the material can be evenly loaded into the bucket, which can avoid the accumulation of material in a certain position in the bucket. The material can be dispersed throughout the bucket, thereby improving the uniformity of material loading and the loading efficiency without moving the mining truck 100.

[0063] Among them, by arranging the discharge pipe 22 below the feed hopper 21, it is convenient for materials such as gravel to slide smoothly into the truck bucket along the discharge pipe 22, avoiding accidents such as material splashing.

[0064] Specifically, the feed hopper 21 can be movably arranged on the bucket wheel excavator body 1 in various ways. For example, the feed hopper 21 can be movably arranged on the bucket wheel excavator body 1 via a hydraulic slide 23 and a sliding plate 24, wherein the feed hopper 21 is connected to the sliding plate 24, and the sliding plate 24 is slidably connected to the hydraulic slide 23. Alternatively, the feed hopper 21 is arranged on the bucket wheel excavator body 1 via an electric telescopic rod.

[0065] Since the feed hopper 21 is usually funnel-shaped, that is, the size of its bottom is smaller than the size of its top, and the feed hopper 21 is usually connected to the sliding plate 24 through its bottom, the connection area between the feed hopper 21 and the sliding plate 24 is small, and the installation strength is low. In order to solve this technical problem, see Figure 1 and Figure 6 The feed hopper mechanism 2 may further include a protective plate 27, the top surface of the protective plate 27 being connected to the bottom of the feed hopper 21, the bottom of the protective plate 27 being connected to the sliding plate 24, and the feed hopper 21 being connected to the sliding plate 24 through the protective plate 27, thereby increasing the connection area between the feed hopper 21 and the sliding plate 24, and improving the installation strength of the feed hopper 21, thereby improving the movement stability of the feed hopper 21.

[0066] In some embodiments, see Figure 1 、 Figure 2 and Figure 5 A conveyor 7 is provided on the top of the bucket wheel excavator body 1. The end of the conveyor 7 extends above the feed hopper 21, and the projection of the end of the conveyor 7 in the direction of the feed hopper 21 is located within the opening of the feed hopper 21. In other words, the opening size of the feed hopper 21 can be larger than the width of the conveyor 7. By providing a feed hopper 21 with a larger opening, it is easier to receive gravel falling from the conveyor 7, preventing the gravel from falling outside the feed hopper and being difficult to clean up.

[0067] In some embodiments, see Figure 1 and Figure 6 The feed hopper mechanism 2 may further include a control valve 25 and a height detection component 26, which are respectively arranged at the discharge port 221. The control valve 25 is used to open or close the discharge port 221, and the height detection component 26 is used to detect the stacking height of the material in the bucket of the mining truck 100 and generate a corresponding second electrical signal.

[0068] When the mining truck 100 enters the bucket wheel excavator body 1 and stops, the head end of the bucket of the mining truck 100 is aligned with the discharge port 221 .

[0069] When the mining truck 100 enters the bucket wheel excavator body 1 along the limited channel and stops, the conveyor 7 can be controlled to open for a period of time and then closed to transport the excavated crushed stone materials to the feed hopper 21. Then the control valve 25 can be opened to allow the materials to fall into the mining truck 100 along the discharge pipe 22. During this process, the height detection component 26 detects the material accumulation height in real time. When the height of the material reaches a specified height, the feed hopper 21 can be controlled to slowly move a preset distance toward the rear end of the mining truck 100 bucket, thereby changing the discharge position and continuing to discharge the material. Until the height detection component 26 detects that the material height reaches the specified height again, the feed hopper 21 can be controlled to slowly move a preset distance toward the rear end of the mining truck 100 bucket again, thereby changing the discharge position and continuing to discharge the material. This reciprocating process continues until the bucket is full of materials. The control valve 25 is closed, thereby better improving the uniformity of material loading and eliminating the need to coordinate the movement of the mining truck 100, further improving loading efficiency.

[0070] Specifically, the height detection component 26 may be an infrared distance sensor.

[0071] In some embodiments, see Figure 1 、 Figure 3 and Figure 4 The bucket wheel excavator loading and alignment device may further include an alarm component 7, which is provided on the bucket wheel excavator body 1 and is used to issue a warning message.

[0072] When the mining truck 100 comes into contact with the limit portion and stops, the alarm component 7 can be controlled to issue an alarm message to prompt the driver of the mining truck 100 to turn off the engine; when loading is completed, the alarm component 7 can be controlled to issue an alarm message to prompt the driver of the mining truck 100 to drive the truck out of the bucket wheel excavator.

[0073] Specifically, the alarm component 7 may include a sound 71 and a warning light 72 , and the sound 71 and the warning light 72 may be arranged on the upper portion of the limiting plate 5 so as to remind the driver of the mining truck 100 .

[0074] In some embodiments, see Figure 1 The bucket wheel excavator loading and alignment device may further include a control room 8, which is arranged on the bucket wheel excavator body 1 and can be electrically connected to the limit mechanism, the direction detection component, the conveyor 7, the hydraulic slide for controlling the movement of the feed hopper 21, the control valve 25, the height detection component 26 and the alarm component 7 to control each of the above mechanisms respectively.

[0075] like Figure 7 As shown, an embodiment of the present invention further provides a bucket wheel excavator loading alignment method, which is applied to the aforementioned bucket wheel excavator loading alignment device, and the alignment method includes:

[0076] 101. The two guide plate assemblies of the control limit mechanism extend to the bottom of the bucket wheel excavator body to form a limit channel.

[0077] 102. After the mining truck enters the limit channel and stops by touching the limit part, the conveyor is controlled to start and continue for a preset time to transport the material to the feed hopper mechanism.

[0078] After the bucket wheel excavator is in motion and loading is required, the control room controls the extension of the four telescopic members of the guide plate assembly, causing the four guide plates to form a restricted channel. The mining truck can then enter the restricted channel and follow it into the bucket wheel excavator until it hits the stop and stops. It can be understood that at this point, the mining truck's bucket is aligned with the discharge opening of the feed hopper mechanism.

[0079] After the mining truck stops, the control room controls the alarm component to issue a warning message, including an audio warning sound and all warning lights turning red to prompt the mining truck driver to turn off the engine in preparation for loading.

[0080] After the mining truck is turned off, the conveyor can be controlled by the control room to open and close after a preset time to transport the excavated crushed stone materials to the feed hopper of the feed hopper mechanism.

[0081] 103. The control valve of the feed hopper mechanism is opened to allow the material to fall into the mining truck.

[0082] After the conveyor transports the material to the feed hopper of the feed hopper mechanism, the control valve of the feed hopper mechanism can be controlled to open through the control room to allow the material to fall into the mining truck for loading.

[0083] 104. When the height detection component of the hopper mechanism detects that the height of the material in the mining truck reaches a preset height, the feed hopper of the hopper mechanism is controlled to move a preset distance in a preset direction until the height detection component detects that the height of the material reaches the preset height a preset number of times, and the control valve is controlled to close.

[0084] The preset distance can be determined based on the length of the mining truck's bucket. Specifically, two or more unloading locations can be pre-designated on the bucket based on the uniformity of loading. These two or more unloading locations can be spaced apart along the length of the bucket, with the distance between two adjacent unloading locations being the preset distance. For example, the preset number of times can be three, and the number of unloading locations can be three. The first unloading location can be located at the head of the bucket, the second at the middle of the bucket, and the third at the rear of the bucket, to achieve uniform loading of the mining truck.

[0085] It should be noted that the parking position of the mining truck after entering the bucket wheel excavator body can be a position in which the discharge port is aligned with the first unloading position. In this case, the feed hopper moves toward the tail of the truck during loading; or, the parking position of the mining truck after entering the bucket wheel excavator body can be a position in which the discharge port is aligned with the third unloading position. In this case, the feed hopper moves toward the head of the truck during loading.

[0086] During the loading process, the height detection component detects the loading height of the material in the mining truck in real time. When the loading height of the unloading position reaches the preset height, the control room can control the feed hopper to move the preset distance so that the discharge port is aligned with the next unloading position in the bucket. When the loading height of the unloading position reaches the preset height, the feed hopper is controlled to continue to move the preset distance so that the discharge port is aligned with the next unloading position in the bucket. Until all unloading positions are loaded, the control valve can be closed through the control room and loading is completed.

[0087] The bucket wheel excavator loading and alignment method provided by an embodiment of the present invention has a limiting channel that can limit the driving path of the mining truck so that the mining truck can drive into the bucket wheel excavator body along the limiting channel. Moreover, the mining truck can stop under the limiting action of the limiting part and align the bucket of the mining truck with the discharge port of the feed hopper mechanism, thereby realizing rapid alignment of the mining truck and the bucket wheel excavator. During the alignment process, there is no need for manual communication, the operation is more convenient, manpower is saved, and the loading efficiency is improved.

[0088] Because the feed hopper mechanism is movably mounted on the bucket wheel excavator body, once the mining truck and bucket wheel excavator are aligned, the feed hopper mechanism can be controlled to move relative to the bucket wheel excavator body. This allows the feed hopper mechanism to change its unloading position within the mining truck bucket, thereby improving material loading uniformity and preventing accumulation of material in a single location in the bucket. Furthermore, uniform loading eliminates the need to coordinate the movement of the mining truck, further improving loading efficiency.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
