[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention adopts a unique impact-shear composite structure by providing an impact unit and a shear unit. The concrete block raw material will first be impacted at high speed by the crushing unit, and the large concrete blocks will be initially crushed. Then, the crushed concrete blocks will be cut by the shear unit during the falling process and further sheared and crushed. This composite method can fully utilize the advantages of both impact and shear forces, greatly improving the crushing efficiency, and is particularly suitable for concrete blocks with high hardness and complex structure.

[0025] 2. The present invention sets an impact unit, and the concrete blocks will fall onto the holding table. The induction plates in each area of the gravity sensor will detect which area has more concrete blocks, and will transmit the information to the processor to facilitate the adjustment mechanism to adjust the position of the shearing unit. After the adjusting rotary handle drives the holding table to rotate, the small concrete blocks will fall freely, and the shearing unit will cut the location where the small concrete blocks gather in a targeted manner.

[0026] 3. The present invention sets a shearing unit and an adjustment unit. After the gravity sensor module transmits information to the processor, the processor controls the servo motor 1 to rotate, thereby controlling the moving block to move back and forth and stop. During this process, the micro cylinder will extend according to demand and drive the insertion rod to enter the limit block. Then the moving block moves again and drives the sliding block 1 to move to a specific position. At the same time, as the shearing work proceeds, the visual monitor will observe the cutter. When it is detected that the hardness of the concrete block changes or the tool wear is uneven, the moving block and the micro cylinder cooperate to make gear 1 and gear 2 engage, and the micro motor will drive the rotating shaft 1 and gear 1 to rotate, thereby causing the rotating rod and the cutter to rotate at a certain angle, so that the tool can always shear in the best state.

[0027] 4. The present invention provides a grinding mechanism. Servo motor 2 drives rotating shaft 2, the main gear, and the sun grinding wheel to rotate, and drives the planetary grinding wheel to rotate through the transmission of the main gear and the secondary gear. At the same time, the top cover is opened to add the grinding medium, so that the grinding medium and the concrete block are ground between the sun grinding wheel and the planetary grinding wheels. The concrete block is subjected to the dual grinding action of the central sun grinding wheel and the planetary grinding disc. This design enables the concrete block to be subjected to a more comprehensive and uniform grinding force during the grinding process, greatly shortening the grinding time and improving the grinding quality.

[0028] 5. The present invention provides a grinding mechanism. When processing concrete blocks with higher hardness, the hydraulic device will control the extension of hydraulic rod 2, so that the distance between the protruding grinding block and the planetary grinding wheel becomes smaller, thereby increasing the grinding pressure on the concrete block. This adjustable pressure structure can adjust the grinding force in real time according to the characteristics of the concrete block, thereby improving the grinding quality and efficiency.

[0044] Example 1: Use Figures 1-13 A concrete block crushing and grinding device according to one embodiment of the present invention is described below.

[0045] like Figure 1-Figure 3 As shown, a concrete block crushing and grinding device of the present invention includes a placement table 1, a processing chamber 2 is provided on the top of the placement table 1, and further includes:

[0046] An impact unit 3 for impacting the concrete at high speed, a shearing unit 5 operating in combination with the impact unit 3, an adjustment unit 4 for changing the position of the shearing unit 5, and a crushing unit 9 for repeatedly grinding the concrete;

[0048] When the present invention is working, the concrete block is first placed in the impact unit 3 to be impacted and broken into small particles, then passes through the shearing unit 5 for further cutting, and finally enters the crushing unit 9 to be ground into fine powder.

[0049] Using a unique impact-shear composite structure, the concrete block raw material will first be impacted at high speed by the crushing unit 9, and the large concrete blocks will be initially crushed. Then, during the falling process, the crushed concrete blocks will be cut by the shear unit 5 and further sheared and crushed. This composite method can fully utilize the advantages of both impact and shear forces, greatly improving the crushing efficiency, and is particularly suitable for concrete blocks with higher hardness and complex structure.

[0052] After the concrete blocks are placed into the side box 31 through the discharge port 32, the hydraulic rod 33 will quickly extend and drive the impact plate 34 to push the concrete blocks to move. Finally, the concrete blocks will be squeezed and impacted by the impact plate 34 and the force plate 310 to become small granular concrete blocks. These concrete blocks will fall onto the holding platform 37. The induction plates 39 in various areas of the gravity sensor 38 will detect which area has more concrete blocks, and will transmit the information to the processor 43 to facilitate the adjustment mechanism to adjust the position of the shearing unit 5. After the adjusting rotary handle 36 drives the holding platform 37 to rotate, the small concrete blocks will fall freely, and the shearing unit 5 will cut the positions where small concrete blocks gather in a targeted manner.

[0058] After the gravity sensor module transmits the information to the processor 43, the processor 43 controls the servo motor 42 to rotate, thereby controlling the moving block 45 to move back and forth and stop. During this process, the micro cylinder 46 will extend as needed, and the micro motor 49 will also operate according to actual conditions and drive the gear 411 to rotate.

The outer surface of the rotating rod 54 is fixedly connected to the cutter 57, and the end of the rotating rod 54 away from the gear 2 56 is rotatably connected to the sliding block 2 58.

[0061] The micro cylinder 46 will extend as needed and drive the insertion rod 48 into the limit block 55. Then the moving block 45 will move again and drive the sliding block 52 to move to a specific position. At the same time, as the shearing work proceeds, the visual monitor 10 will observe the cutter 57.

[0062] The side grooves 51 are provided on both sides of the processing chamber 2 , and the outer surface of the second sliding block 58 is slidably connected to the outer surface of the side grooves 51 .

[0063] The specific workflow is as follows:

[0064] During operation, after the concrete blocks are placed into the side box 31 through the discharge port 32, the hydraulic rod 33 will quickly extend and drive the impact plate 34 to push the concrete blocks to move. Finally, the concrete blocks will be squeezed and impacted by the impact plate 34 and the force plate 310, and become small granular concrete blocks. These concrete blocks will fall onto the holding table 37, and the induction plates 39 of each area on the gravity sensor 38 will detect which area has more concrete blocks. After the gravity sensor module transmits the information to the processor 43, the processor 43 will control the servo motor 42 to rotate, thereby controlling the moving block 45 to move back and forth. Stop. During this process, the micro cylinder 46 will extend as needed and drive the insertion rod 48 to enter the limit block 55. Then the moving block 45 will move again and drive the sliding block 52 to move to a specific position. At the same time, as the shearing work proceeds, the visual monitor 10 will observe the cutter 57. When it is detected that the hardness of the concrete block changes or the tool wear is uneven, the moving block 45 and the micro cylinder 46 cooperate to make the gear 1 411 and the gear 2 56 engage, and the micro motor 49 will drive the rotating shaft 1 410 and the gear 1 411 to rotate, so that the rotating rod 54 and the cutter 57 rotate at a certain angle.

[0065] Example 2: Use Figures 1-13 A concrete block crushing and grinding device according to one embodiment of the present invention is described below.

[0078] The specific workflow is as follows:

[0079] During operation, after the concrete has been processed by the impact unit 3 and the shear unit 5, the telescopic rod 7 will drive the push plate 8 to move and push the concrete block to the pouring inlet 94 and finally fall into the grinding mechanism 96, and the servo motor 99 will drive the rotating shaft 961 and the main gear 962 and the sun grinding wheel 963 to rotate, and drive the planetary grinding wheel 966 to rotate through the transmission of the main gear 962 and the secondary gear 965. At the same time, the top cover 93 is opened to add the grinding medium, so that the grinding medium and the concrete block are ground between the sun grinding wheel 963 and the planetary grinding wheel 966, and are subjected to the dual grinding action of the center sun grinding wheel 963 and the planetary grinding disc. When processing concrete blocks with higher hardness, the hydraulic device 967 will control the hydraulic rod 968 to extend, so that the distance between the protruding grinding block 969 and the planetary grinding wheel 966 becomes smaller, thereby increasing the grinding pressure on the concrete block.
