Description

Technical Field

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

[0002] Water conservancy construction refers to construction projects undertaken to develop and utilize water resources, prevent and control floods and droughts, and protect the water environment. It includes the construction and management of facilities such as dikes, hydropower stations, and river regulation projects. Concrete is an important building material in water conservancy construction, which can fully ensure the stability of water conservancy projects, resist various water disasters, and protect the safety of water conservancy facilities.

[0003] Existing technologies often have the following problems when used:

[0004] Concrete crushers used in water conservancy construction typically employ a double-rotor crushing method. However, this method can only achieve single-pass crushing and is often unsuitable for operations requiring a high degree of crushing. Furthermore, during the crushing process, there may be concrete blocks with relatively smooth surfaces, which are difficult to crush thoroughly, thus affecting the crushing effect and the overall efficiency of the crushing operation. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a crusher for water conservancy construction, which can effectively solve the problems that the single crushing method in the existing technology has a low degree of crushing of concrete, and that the relatively smooth surface of concrete blocks will affect the crushing effect and the overall efficiency of crushing operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a crusher for water conservancy construction, including a box body, a crushing partition plate fixedly connected to the inner wall of the box body, a plurality of screen holes opened on the crushing partition plate, and repeated crushing components opened on the two side walls of the box body.

[0008] The repeated crushing assembly includes two limiting holes opened on the two side walls of the housing, a rotating shaft slidably connected in the two limiting holes, a crushing roller fixedly connected to the outer wall of the rotating shaft, and two reciprocating drive components fixedly connected to the outer wall of the housing.

[0009] Two secondary crushing components are fixedly connected to the top surface of the box.

[0010] Furthermore, the crushing baffle is configured with an inverted convex structure, and the middle part of the crushing baffle and the limiting hole are both configured with an arc-shaped structure.

[0011] Furthermore, the reciprocating drive component includes a rotating bracket fixedly connected to the outer wall of the housing, a reciprocating screw rotatably connected to the rotating bracket, a rotary motor fixedly connected to the outer wall of the rotating bracket, the output end of the rotary motor fixedly connected to the end of the reciprocating screw, a slider threadedly connected to the reciprocating screw, a telescopic rod fixedly connected to the top of the slider, and the output end of the telescopic rod rotatably connected to the end of the rotating shaft through a bearing.

[0012] Furthermore, the secondary crushing component includes a hydraulic push rod fixedly connected to the top surface of the housing, a pressure plate fixedly connected to the output end of the hydraulic push rod, and several extrusion blocks fixedly connected to the bottom of the pressure plate and the top of the crushing partition.

[0013] Furthermore, a sector gear is fixedly connected to the outer wall of the housing, and a transmission gear is fixedly connected to the end of the rotating shaft located outside the housing, and the transmission gear meshes with the sector gear.

[0014] Furthermore, the top of the box is provided with a feed inlet, the lower end of the inner wall of the box is fixedly connected with a feed plate with an inclined structure, and the lower end of the side wall of the box is provided with a discharge outlet.

[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0016] This invention incorporates a repetitive crushing component. By driving the crushing roller to reciprocate relative to the crushing partition, the crushing roller repeatedly crushes the concrete block. Simultaneously, the crushing roller can rotate during its reciprocating movement to increase the friction between the crushing roller and the concrete block, thereby enhancing the degree of crushing of the concrete block.

[0017] This invention incorporates a two-stage crushing assembly. During the repeated crushing of the concrete block by the crushing roller, the crushing roller will squeeze the relatively smooth concrete block to both sides of the top of the crushing baffle. At this time, the pressure plate is driven to move down by the hydraulic push rod. The pressure plate and the crushing baffle are used to fully crush the concrete block, thereby effectively improving the crushing effect of the concrete block and the overall efficiency of the crushing operation.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: Refer to Figures 1 to 3 A crusher for hydraulic construction includes a housing 1. A crushing baffle 2 is fixedly connected to the inner wall of the housing 1. The crushing baffle 2 has several screen holes and is arranged in an inverted convex structure. A feed inlet 15 is located at the top of the housing 1. A discharge plate 16, arranged in an inclined structure, is fixedly connected to the lower end of the inner wall of the housing 1, located directly below the crushing baffle 2. A discharge outlet 17 is located at the lower end of the side wall of the housing 1. Repeated crushing components are located on the two side walls of the housing 1. The repeated crushing components include two limiting holes 3 located on the two side walls of the housing 1. Both the middle part of the crushing baffle 2 and the limiting holes 3 are arranged in an arc shape. A rotating shaft 4 is slidably connected inside the limiting hole 3. A crushing roller 5 is fixedly connected to the outer wall of the rotating shaft 4. Two reciprocating drive components are fixedly connected to the outer wall of the box 1. The reciprocating drive components include a rotating bracket fixedly connected to the outer wall of the box 1, a reciprocating screw 6 rotatably connected to the rotating bracket, a rotary motor 7 fixedly connected to the outer wall of the rotating bracket, the output end of the rotary motor 7 fixedly connected to the end of the reciprocating screw 6, a slider 8 threadedly connected to the reciprocating screw 6, an abutment block fixedly connected to the outer wall of the slider 8, the abutment block fitting against the outer wall of the box 1, and a telescopic rod 9 fixedly connected to the top of the slider 8. The output end of the telescopic rod 9 is rotatably connected to the end of the rotating shaft 4 through a bearing.

[0026] The reciprocating screw 6 is driven to rotate by the rotary motor 7, which causes the slider 8 on the reciprocating screw 6 to drive the telescopic rod 9 to move back and forth, thereby driving the rotating shaft 4 and the crushing roller 5 to move back and forth. During this process, the limiting hole 3 limits the movement of the rotating shaft 4, so that the crushing roller 5 can move back and forth relative to the middle of the crushing partition 2, so as to repeatedly crush the concrete block with the crushing roller 5 and improve the crushing degree of the concrete block.

[0027] Reference Figure 1 A sector gear 13 is fixedly connected to the outer wall of the housing 1, and a transmission gear 14 is fixedly connected to the end of the rotating shaft 4 located outside the housing 1. The transmission gear 14 and the sector gear 13 mesh with each other.

[0028] During the reciprocating movement of the rotating shaft 4 under the limiting action of the limiting hole 3, the crushing roller 5 can be driven to rotate by the meshing transmission of the transmission gear 14 and the sector gear 13, so as to increase the friction of the crushing roller 5 on the concrete block and thus improve the crushing degree of the concrete block.

[0029] Reference Figure 2 and Figure 3 Two secondary crushing components are fixedly connected to the top surface of the box 1. The secondary crushing components include a hydraulic push rod 10 fixedly connected to the top surface of the box 1. A pressure plate 11 is fixedly connected to the output end of the hydraulic push rod 10. Several extrusion blocks 12 are fixedly connected to the bottom of the pressure plate 11 and the top of the crushing partition 2.

[0030] When crushing concrete blocks, the crushing roller 5 will squeeze the relatively smooth concrete blocks to the top sides of the crushing baffle 2. During this process, the hydraulic push rod 10 can be activated to drive the pressure plate 11 to move down. The pressure plate 11 and the extrusion blocks 12 on the crushing baffle 2 will fully crush the concrete blocks, thereby effectively improving the crushing effect of the concrete blocks and the overall efficiency of the crushing operation.

[0031] The working principle of this utility model is as follows:

[0032] 1. In use, the concrete block raw material to be crushed is fed into the box 1 above the crushing partition 2 through the feed port 15. The rotary motor 7 is started and driven to rotate the reciprocating screw 6. The slider 8 on the reciprocating screw 6 starts to drive the telescopic rod 9 to move back and forth, which in turn drives the rotating shaft 4 and the crushing roller 5 to move back and forth. During this process, the limiting hole 3 limits the movement of the rotating shaft 4, so that the crushing roller 5 can move back and forth relative to the middle of the crushing partition 2, so that the crushing roller 5 can repeatedly crush the concrete block. At the same time, the crushing roller 5 can be driven to rotate by the meshing of the transmission gear 14 and the sector gear 13 to increase the friction of the crushing roller 5 on the concrete block, thereby improving the crushing degree of the concrete block.

[0033] 2. When the crushing roller 5 moves back and forth to repeatedly crush the concrete block, the crushing roller 5 will squeeze the relatively smooth concrete block to the top two sides of the crushing partition 2. During this process, the hydraulic push rod 10 can be started, and the pressure plate 11 can be driven to move down through the hydraulic push rod 10. The pressure plate 11 and the extrusion block 12 on the crushing partition 2 are used to fully crush the concrete block, thereby effectively improving the crushing effect of the concrete block and the overall efficiency of the crushing operation.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
