[0027] See also Figure 1-7 As shown, a mobile vibration-damping crusher includes a housing 1 mounted on a base 2; mounting slots 3 are provided on both parallel sides of the housing 1, and protective components are provided in both mounting slots 3; elastic support components are installed on both outer walls of the housing 1 where the mounting slots 3 are provided, and the elastic support components are used to support the protective components to move in the mounting slots 3; a crushing component is provided between the protective components on both sides, and the crushing component is horizontally arranged in the housing 1;

[0028] The elastic support assembly includes four fixed shafts 14 and two horizontal rods 11 arranged parallel to the upper and lower sides of the mounting groove 3. The two ends of the two horizontal rods 11 are fixed to the side wall of the housing 1 through fixed plates 10 respectively. Slide sleeves 12 are slidably provided on the two horizontal rods 11. The ends of the two horizontal rods 11 are sleeved with No. 1 springs 13, and the four No. 1 springs 13 are respectively located between the corresponding fixed plates 10 and the slide sleeves 12 at the ends of the two horizontal rods 11. A rotating seat 21 is installed on the inner side of the four slide sleeves 12;

[0029] The four fixed shafts 14 are symmetrically fixed to the side surfaces of the outer guard plate 5 in the upper and lower directions. A sleeve 15 is rotatably sleeved on each of the four fixed shafts 14. A damping rod No. 1 is fixed to each of the four sleeves 15. The active ends of the four damping rods No. 1 are rotatably mounted on four rotating seats 21 respectively, and the active ends of the four damping rods No. 1 are symmetrically arranged outward in an X shape. The active ends of the four damping rods No. 1 are fixed to a baffle 17. A No. 2 spring 18 is sleeved on each of the four damping rods No. 1, and the No. 2 spring 18 is located between the corresponding baffle 17 and the sleeve 15.

[0030] The protection assembly includes a plurality of connecting rods 6, and the plurality of connecting rods 6 are horizontally arranged in the mounting groove 3. The two ends of the connecting rods 6 are respectively fixed with the inner guard plate 4 and the outer guard plate 5. Two shaft sleeves 7 are simultaneously arranged between the inner guard plate 4 and the outer guard plate 5. The inner guard plate 4 is located inside the shell 1, and the outer guard plate 5 is located outside the shell 1.

[0031] The housing 1 is provided with an opening at the top, and two guide plates 22 are symmetrically arranged in the opening, and the bottom ends of the two guide plates 22 are symmetrically inclined inwardly, and the ends of the fixed shaft 14 are fixedly connected to the limit plates 19.

[0032] A discharge port 30 is provided at the bottom side of the shell 1 , and a guide plate 23 is obliquely installed in the shell 1 through the discharge port 30 , and the guide plate 23 is located below the crushing assembly, and the end of the guide plate 23 outside the shell 1 is obliquely downwardly arranged.

[0033] The crushing assembly includes two parallel rotating shafts 8, and the two ends of the two rotating shafts 8 respectively pass through the two sleeves 7 in the protective assembly on both sides of the shell 1. The two rotating shafts 8 are both provided with crushing rollers 9, and the crushing rollers 9 are located in the shell 1. The ends on the same side of the two rotating shafts 8 are fixedly connected to the first pulley 20.

[0034] Two motors 24 are mounted on the base 2 via fixing members. The output ends of the two motors 24 are fixedly connected to a second pulley 25 . A transmission belt 26 for transmission is respectively provided between the two second pulleys 25 and the two first pulleys 20 .

[0035] Four No. 2 damping rods 27 are symmetrically installed under the base 2, and the bottom ends of the four No. 2 damping rods 27 are fixedly connected to universal wheels 28. The four No. 2 damping rods 27 are all sleeved with No. 3 springs 29, and the No. 3 springs 29 are located between the universal wheels 28 and the base 2.

[0036] During operation, since the vibration generated by the crusher during use is mainly caused by the stress release generated when the crushing roller crushes the material, the crushing roller in the existing crusher cannot block the vibration generated by the crushing roller during use. During use, the vibration will be transmitted to other parts of the crusher, causing the welded joints to become unsoldered and the bolted joints to become loose, and resulting in poor vibration reduction effect. In this solution, in the initial state, the No. 2 spring 18 will always push the baffle 17 to one side of the baffle 17, so that the No. 1 damping rod 16 remains in an extended state, so that the weight of the protective assembly and the crushing assembly installed inside the protective assembly is transferred to the sliding sleeve 12 through the No. 1 damping rod 16 and the No. 2 spring 18, and the sliding sleeve 12 then transfers the weight to the horizontal rod 11, so as to support the protective assembly to move in the installation groove 3, thereby ensuring that the crushing assembly can be kept horizontally in the shell 1 for crushing work, and the sliding sleeve 12 always pushes the No. 1 spring 13 to the outside;

[0037] In the initial state, the No. 1 spring 13 will always push the sliding sleeve 12 inward, so that the sliding sleeve 12 and the fixed plate 10 maintain a certain distance. When the vibration of the crushing assembly causes the protective assembly to deviate in the installation slot 3, the sliding sleeve 12 can slide on the horizontal rod 11 to offset the deflection force.

[0038] In the initial state, the third spring 29 will always lift the base 2 upward, so that the second damping rod 27 remains in the extended state. When the vibration is transmitted to the base 2, the vibration force can be weakened to prevent the vibration from being transmitted to the bottom surface structure and causing damage to the bottom surface structure;

[0039] During normal use, when the two motors 24 are running, they will drive the No. 2 pulleys 25 on their output shafts to rotate. When the two No. 2 pulleys 25 rotate, they will respectively drive the No. 1 pulley 20 installed at the ends of the two rotating shafts 8 to rotate through the transmission belt 26. The transmission is carried out through the transmission belt 26, which can prevent the vibration from being transmitted to the No. 2 pulley 25 through the No. 1 pulley 20. The crushing roller 9 is driven to rotate in the shell 1 through the rotating shaft 8. The two crushing rollers 9 are controlled to rotate inward at the same time, and the material is put into the opening at the top of the shell 1. Under the guidance of the two guide plates 22, the material enters between the two crushing rollers 9 for crushing. The crushed material will fall downward onto the guide plate 23 and be discharged from the shell 1 from the discharge port 30 under the guidance of the guide plate 23.

[0040] When the crushing roller 9 is crushed, it generates vibration, which is transmitted to the shaft sleeve 7 through the rotating shaft 8, and then transmitted from the shaft sleeve 7 to the inner guard plate 4 and the outer guard plate 5 on both sides, and then transmitted to the No. 1 damping rod 16 and the No. 2 spring 18 through the fixed shaft 14. When the vibration is transmitted to the No. 1 damping rod 16 and the No. 2 spring 18, the vibration will cause the No. 2 spring 18 to resonate, and under the action of the No. 1 damping rod 16, the vibration generated by the No. 2 spring 18 can be weakened, and when the No. 1 damping rod 16 weakens the vibration of the No. 2 spring 18, it will drive the sliding sleeve 12 to slide on the horizontal rod 11. , and the sleeve 12 will always push the spring 13 outward under the action of the gravity of the crushing assembly and the protective assembly, and the sleeve 12 will be pushed back to its original position under the reaction force of the spring 13. When the vibration force is transmitted to the inner guard plate 4 and the outer guard plate 5, the inner guard plate 4 and the outer guard plate 5 will shake at the opening of the mounting groove 3 respectively, thereby preventing the vibration of the inner guard plate 4 and the outer guard plate 5 from being directly transmitted to the shell 1, and the combination achieves the effect of vibration reduction. Compared with the traditional crusher, the vibration reduction effect is better, and it can block the vibration generated by the crushing roller to prevent the crusher welding connection from being damaged due to vibration.
