Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, specifically to a crushing device for water conservancy construction. Background Technology

[0002] Water conservancy construction refers to the development of water resources and the construction of flood prevention facilities. Water conservancy construction requires the use of a large amount of stones for laying, filling and other work, so special crushing equipment is needed to crush large stones into smaller pieces for use.

[0003] However, the existing crushers have a fixed crushing ratio, which cannot be adjusted according to construction requirements. When the crushing ratio does not meet the requirements, crushers of different specifications can only be used for crushing. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a crushing device for water conservancy construction, which addresses the above-mentioned shortcomings. This application can connect two crushing boxes with different input particle size ranges as needed to change the crushing ratio of the crushing device.

[0005] To solve the above technical problems, the present invention adopts the following technical solution:

[0006] A crushing device for hydraulic construction includes a frame, a first crushing box, a second crushing box, and a translation mechanism. The first crushing box and the translation mechanism are both mounted on the frame. The translation mechanism is located below the first crushing box, and the second crushing box is mounted on the translation mechanism. The translation mechanism enables the second crushing box to be translated so that the first crushing box and the second crushing box can be connected or separated. The feed particle size range of the second crushing box is smaller than that of the first crushing box.

[0007] Furthermore, the translation mechanism includes roller bars and a locking mechanism. Two parallel roller bars are horizontally arranged on the frame, the second crushing box is disposed between the two roller bars, and guide bars that cooperate with the roller bars are provided on both sides of the second crushing box.

[0008] The locking mechanism is used to restrict the second crushing box from sliding along the roller strip. At least two locking mechanisms are provided on the frame, and the two locking mechanisms are respectively arranged in a first position and a second position. When the locking mechanism in the first position locks with the second crushing box, the second crushing box is connected to the first crushing box; when the locking mechanism in the second position locks with the second crushing box, the second crushing box is separated from the first crushing box.

[0009] Furthermore, the locking mechanism includes a C-shaped frame, a pin, and a spring. The C-shaped frame is mounted on the frame, the pin passes through the C-shaped frame, and a limit ring is provided on the pin. Both the limit ring and the spring are located in the inner region of the C-shaped frame.

[0010] The guide bar is provided with a first positioning hole that mates with the pin, and the spring can provide elastic force to move the pin toward the first positioning hole.

[0011] Furthermore, a limit frame is provided at the end of the roller strip.

[0012] Furthermore, a feed hopper is provided above the first crushing box.

[0013] Furthermore, a discharge hopper is detachably provided on the frame. The discharge hopper can be installed in at least the third position and the fourth position. When the discharge hopper is installed in the third position, it is connected to the second crushing box; when the discharge hopper is installed in the fourth position, it is connected to the first crushing box.

[0014] Furthermore, a fixing frame is provided on the discharge hopper, and a number of second positioning holes are provided on the frame from top to bottom. The fixing frame is fixed to the frame with screws.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0016] This application allows the second crushing box to be connected to the first crushing box according to construction needs, thereby changing the crushing ratio of the crushing device. With the input stone particle size remaining unchanged, it can output stone of two different particle sizes, making it flexible in use.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, a crushing device for hydraulic construction includes a frame 1, a first crushing box 2, a second crushing box 3, and a translation mechanism 4. The first crushing box 2 is located on the upper part of the frame 1, the translation mechanism 2 is located in the middle part of the frame 1, and the second crushing box 3 is located on the translation mechanism 2. The second crushing box 3 can be moved horizontally through the translation mechanism 4, so that the second crushing box 3 can switch between a connected position and a separated position.

[0031] When the second crushing box 3 is in the connected position, the input end of the second crushing box 3 is connected to the output end of the first crushing box 2. After crushing the stone, the first crushing box 2 directly inputs the crushed stone into the second crushing box 3 for secondary crushing and then discharges it. When the second crushing box 3 is in the separated position, the second crushing box 3 is separated from the first crushing box 1. After crushing the stone, the first crushing box 2 directly discharges the crushed stone.

[0032] The feed particle size range of the second crushing box 3 is smaller than that of the first crushing box 2. It can be understood that the second crushing box 3 is used to crush stones with smaller particle sizes.

[0033] like Figure 4 and Figure 5 As shown, in this embodiment, two first crushing rollers 21 are provided inside the first crushing box 2. A first gear 22 is provided on the rotating shaft of the first crushing roller 21. All the first gears 22 mesh with each other. A first driving mechanism 23 is provided on the outside of the first crushing box 2. The first driving mechanism 23 is connected to the rotating shaft of one of the first crushing rollers 21. The first driving mechanism 23 is used to drive all the first crushing rollers 21 to rotate.

The outer side of the second crushing box 3 is provided with a second drive mechanism 34, which is connected to the shaft of one of the second crushing rollers 32. The second drive mechanism 34 is used to drive all the second crushing rollers 32 to rotate.

[0035] The above structural design enables the second crushing box 3 to crush stones with smaller particle sizes.

[0036] like Figure 2 , Figure 3 and Figure 6 As shown, the translation mechanism 4 includes roller strips 41 and locking mechanism 42. Two parallel roller strips 41 are horizontally arranged on the frame 1. The second crushing box 3 is arranged between the two roller strips 41. Guide strips 31 that cooperate with the roller strips 41 are arranged on both sides of the second crushing box 3. The roller strip 41 includes a roller mounting frame. Multiple rollers are arranged on the roller mounting frame. The guide strips 31 are located above the rollers, so that the guide strips 31 can slide along the roller strips 41.

[0037] Locking mechanism 42 is used to restrict the second crushing box 3 from sliding along roller strip 41. At least two locking mechanisms 42 are provided on the frame 1, and the two locking mechanisms 42 are respectively arranged in the first position and the second position, such as... Figure 1 As shown, when the second crushing box 3 is in the connected position, the locking mechanism 42 in the first position can lock into the second crushing box 3; as Figure 7 As shown, when the second crushing box 3 is in the separation position, the locking mechanism 42 of the second position can lock and engage with the second crushing box 3.

[0038] A limit frame 411 is provided at the end of the roller bar 41 away from the frame 1. The limit frame 411 is used to restrict the second crushing box 3 from disengaging from the roller bar. The end of the roller bar 41 close to the frame 1 is used to limit the second crushing box 3 through the frame 1 itself.

[0039] A feed hopper 5 is provided above the first crushing box 2. The feed hopper 5 is connected to the input end of the first crushing box 2 and is used to feed stone into the first crushing box 2.

[0040] A discharge hopper 6 is detachably mounted on the frame 1. The discharge hopper 6 can be installed in at least the third and fourth positions, such as... Figure 1 As shown, when the discharge hopper 6 is installed in the third position, the discharge hopper 6 is connected to the output end of the second crushing box 3; as Figure 7 As shown, when the discharge hopper 6 is installed in the fourth position, the discharge hopper 6 is connected to the output end of the first crushing box 2.

[0041] like Figure 6 As shown, a fixing frame 61 is provided on the discharge hopper 6, and a number of second positioning holes 11 distributed from top to bottom are provided on the frame 1. The fixing frame 61 is fixed to the frame 1 by screws to facilitate the adjustment of the position of the discharge hopper 6.

[0042] Example 2

[0043] The structure of this embodiment is roughly the same as that of Embodiment 1, with the improvement being the provision of a low-cost locking mechanism.

[0044] like Figure 3 As shown, the locking mechanism 42 includes a C-shaped frame 421, a pin 422, and a spring 423. The C-shaped frame 421 is mounted on the frame 1, and the pin 422 passes through the C-shaped frame 421. A limit ring 4221 is provided on the pin 422. The limit ring 4221 and the spring 423 are both located in the inner area of ​​the C-shaped frame 421. The two ends of the spring 423 abut against the limit ring 4221 and the inner wall of the C-shaped frame 421, respectively.

[0045] The guide bar 31 is provided with a first positioning hole 311 that cooperates with the pin 422, and the spring 423 can provide elastic force to move the pin 422 toward the first positioning hole 311.

[0046] When the second crushing box 3 is in the connected or separated position, the pin 422 can be inserted into the first positioning hole 311 to restrict the movement of the second crushing box 3 along the roller strip 41.

[0047] In addition, the second crushing box 3 can also be fixed to the connection position or the separation position by screws.

[0048] Example 3

[0049] This embodiment has a structure that is largely the same as that of Embodiment 1, with the improvement being in the connection structure between the first crushing box and the second crushing box.

[0050] When the second crushing box 3 is in the connected position, in order to prevent the stone from leaking out from the gap between the second crushing box 3 and the first crushing box 2, a flexible sleeve is set between the second crushing box 3 and the first crushing box 2. The flexible sleeve can be made of flexible materials such as rubber, and it is used to fill the gap between the second crushing box 3 and the first crushing box 2.

[0051] Furthermore, grooves are provided on both sides of the bottom of the flexible sheath, and the grooves are arranged along the moving direction of the second crushing box 3. Raised strips that mate with the grooves are provided on both sides of the top of the second crushing box 3.
