Description

Technical Field

[0001] This utility model relates to the field of stone-breaking technology, and in particular to a stone-breaking device with a limiting plate for a mining dump truck. Background Technology

[0002] Heavy-duty mining dump trucks are widely used in various open-pit mines. Due to the need for increased transport volume, their load capacity has gradually increased from 100 tons to 400 tons. Off-highway mining dump trucks generally operate on uneven and harsh road surfaces. Because the road surface is often littered with gravel and sand, large stones often get stuck between the two tires of the double-row truck. If these stones are not cleared in time, they will continuously rub and compress the tires, and may even puncture them, greatly reducing the operating efficiency of the mining dump truck.

[0003] In existing technologies, one method involves a stone-crushing device consisting solely of a suspended iron rod. This type of device has considerable force but lacks flexibility, making it prone to getting stuck between the tires along with the stones, increasing the risk of tire crushing and wear. Another method uses a single iron chain, which, while more flexible, lacks sufficient striking force for larger stones and cannot effectively dislodge stones stuck between the wheels. Furthermore, the iron chain suspended between the double-row tires is easily caught in the grooves of the electric wheel hub, posing a risk of breakage. Additionally, when the chain is covered in soil and clumps together, its flexibility decreases, and its weight increases significantly, increasing the load on the dump truck and reducing transportation efficiency.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to Figures 1 to 4A stone-breaking device with a limiting plate for a mining dump truck includes: a mounting base 10, a stone-breaking rod 13, a limiting component 17, and a clamping component. The mounting base 10 is used to install the stone-breaking device 1 at the bottom of the dump truck's hopper 2. One end of the stone-breaking rod 13 is mounted on the mounting base 10 via the mounting component 11, and the other end of the stone-breaking rod 13 is positioned in the gap between two tires 3 to strike the stones in the gap. The stone-breaking rod 13 is vertically suspended between the two tires 3 and is spaced apart from the wheel axle 4. Figure 3 and Figure 4 As shown; the limiting component 17 is located at the lower end of the mounting base 10, used to limit the rotation angle of the rock-breaking rod 13 and to buffer the impact of the rock-breaking rod 13; the clamping component is installed on the mounting base 10, used to clamp the rock-breaking rod 13 when the tire 3 of the mining dump truck is removed; wherein, the mounting component 11 can realize the quick disassembly and installation of the rock-breaking rod 13.

[0020] To better implement this utility model, refer to Figure 2 and Figure 7 In one embodiment, the limiting component 17 includes a mounting block 171 and a plurality of guide blocks 174. In this embodiment, there are two guide blocks 174, which are vertically mounted on the mounting block 171, so that the stone-hitting rod 13 moves in the gap between the two guide blocks 174 when rotating. The end of the guide block 174 away from the mounting block 171 is wedge-shaped and the inclined surfaces are arranged inward and opposite to each other. The wedge shape can be used to guide the stone-hitting rod 13 to ensure that the stone-hitting rod 13 is located in the middle of the two tires 3, avoid friction between the stone-hitting rod 13 and the tires 3, and prevent the stone-hitting rod 13 from puncturing the tires 3. Mounting block 171 limits the rotation angle of the stone-dispelling rod 13, preventing it from colliding with the wheel axle 4 during operation. Mounting block 171 can be rectangular. When only mounting block 171 is installed, it limits the swing angle of the stone-dispelling rod 13 during operation, preventing it from colliding with the wheel axle 4. The stone-dispelling rod 13 contacts the side of mounting block 171. Since mounting block 171 is installed between the second mounting plate 102 and the third mounting plate 103, the second mounting plate 102 and the third mounting plate 103 can support mounting block 171, and the impact force of the stone-dispelling rod 13 on mounting block 171 can be evenly transmitted to the second mounting plate 102 and the third mounting plate 103.

[0021] In another embodiment, the limiting component 17 further includes an adjusting plate 172 and an elastic element 173. In this case, the mounting plate can also be U-shaped. When the mounting block 171 is U-shaped, the upper end of the adjusting plate 172 is hinged to the upper opening of the mounting block 171, and the lower end of the adjusting plate 172 is connected to the mounting block 171 via the elastic element 173. Both the adjusting plate 172 and the elastic element 173 are located between multiple guide blocks 174. When the stone-disrupting rod 13 is working, it strikes the adjusting plate 172 and compresses it, causing the elastic element 173 to compress and gradually reduce the impact of the stone-disrupting rod 13 on the adjusting plate 172, thus preventing the stone-disrupting rod 13 from being damaged due to long-term impact. To improve the buffering effect on the stone-disrupting rod 13, damping can be provided on the elastic element 173 if necessary.

[0022] To better implement this utility model, refer to Figure 1 and Figure 2 In one embodiment, the mounting base 10 includes a first mounting plate 101, a second mounting plate 102, a third mounting plate 103, and a fourth mounting plate 104. The first mounting plate 101 is mounted on the bottom of the dump truck's hopper 2. The second mounting plate 102 and the third mounting plate 103 are both vertically mounted on the first mounting plate 101. A stone-breaking rod 13 is installed in the gap between the second mounting plate 102 and the third mounting plate 103. The sides of the second mounting plate 102 and the third mounting plate 103 away from the stone-breaking rod 13 are connected by the fourth mounting plate 104. The second mounting plate 102 and the third mounting plate 103 can be hollowed out in the center to reduce the weight of the stone-breaking device 1. The fourth mounting plate 104 installs and fixes the first mounting plate 101, the second mounting plate 102, and the third mounting plate 103. The included angle between the fourth mounting plate 104 and the first mounting plate 101 is an acute angle, thereby increasing the stability of the stone-breaking device 1 structure.

[0023] To better implement this utility model, refer to Figure 2 In one embodiment, the mounting assembly 11 includes a cotter pin 111, a slotted nut 112, and a bolt 113. The bolt 113 passes sequentially through the second mounting plate 102, the rock-breaking rod 13, and the third mounting plate 103 before being threadedly connected to the slotted nut 112. The cotter pin 111 first passes through the slot of the slotted nut 112 and then is inserted into the radial pin hole of the bolt 113 to restrict the loosening of the slotted nut 112. Traditional rock-breaking devices have a risk of the rock-breaking rod 13 falling off during operation. In this embodiment, the conventional smooth rod pin is replaced with a bolt 113 with a pin hole, and the slotted nut 112 and cotter pin 111 are used for locking to prevent loosening, increasing the stability of the rock-breaking device 1. This mounting assembly 11 also allows for faster and more convenient disassembly and installation of the rock-breaking rod 13.

[0024] To better implement this utility model, refer to Figure 2 , Figure 3 and Figure 5 The clamping assembly includes a pin 14 and a pin storage device 15. The pin storage device 15 is mounted on the mounting base 10. The pin 14 is used to insert into the pin holes 16 on the second mounting plate 102 and the third mounting plate 103 when the tire 3 of the mining dump truck is removed, to clamp the rock-breaking rod 13. The pin storage device 15 includes multiple clamping pieces 151 and a pin cylinder 152. Both the multiple clamping pieces 151 and the pin cylinder 152 are mounted on the second mounting plate 102 or the third mounting plate 103, so that when the pin 14 is placed, the first part of the pin 14 is inserted into the pin cylinder 152, and the second part of the pin 14 is clamped between the multiple clamping pieces 151. In this embodiment, there are two clamping pieces 151, which are symmetrically arranged. Since the first and second parts of the pin 14 are perpendicular, the axial direction of the pin cylinder 152 and the clamping piece 151 remain perpendicular, ensuring that the pin 14 can be stably placed between the pin cylinder 152 and the clamping piece 151. To remove the tire 3 located inside the stone-crushing device 1, the conventional stone-crushing device 1 needs to be disassembled for easy removal. In this embodiment, it is not necessary to disassemble the stone-crushing device 1; simply clamping the position of the stone-crushing rod 13 allows for easy removal of the inner tire 3. At this time, inserting the first part of the pin 14 into the mounting holes 131 of the second mounting plate 102 and the third mounting plate 103 allows the stone-crushing rod 13 to move away from between the two tires 3, thus limiting the position of the stone-crushing rod 13. Figure 5 As shown, when removing the inner tire 3, the stone crusher 1 will not interfere with the removal process. When the pin 14 is not needed, it can be placed back between the pin cylinder 152 and the clamping piece 151.

[0025] To better implement this utility model, refer to Figure 2 In one embodiment, the stone-discarding device 1 further includes multiple washers 12, which are fitted onto the bolts 113 and located on both sides of the stone-discarding rod 13 to prevent the stone-discarding rod 13 from shaking. In this embodiment, there are two washers 12, which are respectively located on both sides of the stone-discarding rod 13.

[0026] To better implement this utility model, refer to Figure 6 In one embodiment, the upper part of the stone-dispelling rod 13 is provided with multiple mounting holes 131. In this embodiment, two mounting holes 131 are preferably provided to adjust the swing length of the stone-dispelling rod 13. The end of the stone-dispelling rod 13 away from the mounting base 10 is provided with an arc-shaped bending strip to form a pendulum shape, increasing the striking force. At the same time, the arc shape can protect the tire 3 and prevent the tire 3 from being damaged by the stone-dispelling device 1. The length of the stone-dispelling rod 13 should be set according to actual needs, and the lever arm between the mounting holes 131 and the mounting block 171 should be increased to ensure that the stone-dispelling rod 13 is not easily broken under impact load.

[0027] The stone-crushing device in this embodiment significantly reduces the risk of breakage and tire friction compared to traditional rod-type stone-crushing devices. It can effectively knock down stones and improves the stability and maintainability of the stone-crushing device.

[0028] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
