[0029] Reference Figure 1A transmission speed regulating mechanism comprises: a frame 100, a first transmission belt set 200, a countershaft transmission wheel 450, a second transmission belt set 300 and an adjusting assembly 500, wherein a driving device 800 is arranged on the frame 100; the first transmission belt set 200 is installed on the frame 100, and the driving device 800 is connected to the first transmission belt set 200 and can drive it to move; the countershaft transmission wheel 450 is rotatably connected to the frame 100, and the driving device 800 is connected to the countershaft transmission wheel 450 through the first transmission belt set 200 and can drive it to move; the second transmission belt set 300 is installed on the frame 100, and the countershaft transmission wheel 450 is connected to the second transmission belt set 300 and can drive it to move; the adjusting assembly 500 is connected to the countershaft transmission wheel 450, and the adjusting assembly 500 can drive the countershaft transmission wheel 450 to move relative to the frame 100. After the driving device 800 is started, the secondary shaft drive wheel 450 will be driven to move through the first transmission belt set 200, and the movement of the secondary shaft drive wheel 450 can drive the tool spindle through the second transmission belt set 300, so the driving effect of the tool spindle can be effectively achieved. In addition, since the first transmission belt set 200 and the second transmission belt set 300 jointly adjust the speed between the driving device 800 and the tool spindle, it can also effectively ensure that the operating speed of the tool spindle is effectively adjusted. When the first transmission belt set 200 or the second transmission belt set 300 needs to be tensioned and adjusted, the position of the secondary shaft drive wheel 450 can be changed through the adjustment component 500, and the tension adjustment effect of the first transmission belt set 200 and the second transmission belt set 300 can be achieved through the position change of the secondary shaft drive wheel 450, so as to facilitate accurate driving of the tool spindle.

[0030] In certain embodiments, reference Figure 2 The adjustment assembly 500 includes a swing arm 510, one end of which is rotatably connected to the frame 100, and the countershaft transmission wheel 450 is rotatably connected to the other end of the swing arm 510. Since the countershaft transmission wheel 450 is mounted on the swing arm 510, when the swing arm 510 swings, the countershaft transmission wheel 450 will swing along with it, so that the position between the countershaft transmission wheel 450 and the frame 100 can be adjusted, and then the tension of the first transmission belt set 200 or the second transmission belt set 300 can be adjusted smoothly through the position change of the countershaft transmission wheel 450.

[0031] It is conceivable that the secondary shaft transmission wheel 450 can also be installed on a sliding platform and achieve its displacement purpose through a sliding effect. The specific implementation method can be adjusted accordingly according to actual needs and is not limited here.

[0032] In certain embodiments, reference Figure 3A first adjusting screw 520 is rotatably mounted on the frame 100. The first adjusting screw 520 is connected to the swing arm 510 and can adjust the position of the swing arm 510 relative to the frame 100. When the first adjusting screw 520 rotates, it can push the swing arm 510, so that the swing arm 510 swings, and then the swing arm 510 drives the secondary shaft drive wheel 450 to move directly and effectively, so as to adjust the tension of the first transmission belt set 200 or the second transmission belt set 300.

[0033] In certain embodiments, reference Figure 2 The first transmission belt set 200 includes a first transmission wheel 220 and a first belt 210. The driving device 800 is connected to the first transmission wheel 220 and can drive it to rotate; the first transmission wheel 220 and the secondary shaft transmission wheel 450 are connected through the first belt 210. After the driving device 800 is started, it will drive the first transmission wheel 220 to rotate. When the first transmission wheel 220 rotates, it can drive the first belt 210 to move, so that the rotation of the first transmission wheel 220 can be transmitted to the secondary shaft transmission wheel 450 through the first belt 210, thereby effectively realizing the driving effect of the driving device 800 on the secondary shaft transmission wheel 450.

[0034] In certain embodiments, reference Figure 2 , the radial dimension of the first transmission wheel 220 is smaller than the radial dimension of the secondary shaft transmission wheel 450. Since the radial dimension of the first transmission wheel 220 is smaller, when the first transmission wheel 220 drives the secondary shaft transmission wheel 450 through the first belt 210, the path of the first belt 210 on the secondary shaft transmission wheel 450 is longer, and the rotation speed of the secondary shaft transmission wheel 450 is lower than that of the first transmission wheel 220. Therefore, the reduction transmission effect between the driving device 800 and the secondary shaft transmission wheel 450 can be achieved through the size relationship, thereby avoiding the problem of subsequent damage due to excessive rotation speed.

[0035] It is conceivable that when the deceleration effect is not required, the radial dimension of the first transmission wheel 220 can also be equal to that of the secondary shaft transmission wheel 450, so that the rotation speeds of the two are close to the same. The specific implementation method can be adjusted accordingly according to actual needs and is not limited here.

[0036] In certain embodiments, reference Figure 3 The second transmission belt set 300 includes a second transmission wheel 320 and a second belt 310; the second transmission wheel 320 and the secondary shaft transmission wheel 450 are connected through the second belt 310. When the secondary shaft transmission wheel 450 is driven, it will drive the second belt 310 to move, so that the rotation of the secondary shaft transmission wheel 450 can be transmitted to the second transmission wheel 320 through the second belt 310, and then the secondary shaft transmission wheel 450 can effectively drive the tool spindle through the second transmission wheel 320.

[0037] In certain embodiments, reference Figure 2 , the radial dimension of the second transmission wheel 320 is greater than the radial dimension of the secondary shaft transmission wheel 450. Since the radial dimension of the secondary shaft transmission wheel 450 is smaller, when the secondary shaft transmission wheel 450 drives the second transmission wheel 320 through the second belt 310, the second belt 310 travels a longer path on the second transmission wheel 320, and the rotation speed of the second transmission wheel 320 is lower than that of the secondary shaft transmission wheel 450. Thus, the reduction transmission effect between the driving device 800 and the secondary shaft transmission wheel 450 can be achieved through the size relationship, thereby avoiding the problem of subsequent damage due to excessive rotation speed.

[0038] It is conceivable that when the deceleration effect is not required, the radial dimension of the second transmission wheel 320 can also be equal to that of the secondary shaft transmission wheel 450, so that the rotation speeds of the two are close to the same. The specific implementation method can be adjusted accordingly according to actual needs and is not limited here.

[0039] In certain embodiments, reference Figure 2 The frame 100 is rotatably provided with a transmission shaft 400, and the secondary shaft transmission wheel 450 is installed at the end of the transmission shaft 400; the first transmission belt set 200 is connected to the outer periphery of the secondary shaft transmission wheel 450, and the second transmission belt set 300 is connected to the outer periphery of the transmission shaft 400. The transmission shaft 400 and the secondary shaft transmission wheel 450 are respectively connected with the first transmission belt set 200 and the second transmission belt set 300, and the transmission shaft 400 and the secondary shaft transmission wheel 450 move synchronously, so the first transmission belt set 200 and the second transmission belt set 300 can be effectively connected through the transmission shaft 400 and the secondary shaft transmission wheel 450 as a whole, and the problems of misalignment and disorder when the two are connected can be avoided by distinguishing the transmission shaft 400 and the secondary shaft transmission wheel 450, thereby ensuring the smooth progress of the transmission operation.

[0040] In certain embodiments, reference Figure 3 , a mounting seat 530 is movably provided on the frame 100, a second adjusting screw 540 is installed on the frame 100, the second adjusting screw 540 is connected to the mounting seat 530 and can change the relative position between the mounting seat 530 and the frame 100, and the driving device 800 is installed on the mounting seat 530. After the second adjusting screw 540 pushes the mounting seat 530, the mounting seat 530 will change its position relative to the frame 100, and the driving device 800 installed on the mounting seat 530 and the first transmission wheel 220 connected thereto will change their positions. In this way, the tension adjustment effect of the first transmission belt set 200 can be achieved without changing the position of the secondary shaft transmission wheel 450, and the tension adjustment of the first transmission belt set 200 and the second transmission belt set 300 can be performed separately to ensure that the overall tension can be adjusted to the target area.

[0041] Specifically, the driving device 800 is a motor. Of course, the driving device 800 can also be composed of other components, such as a cylinder driving a nut to rotate through a screw rod, and the nut is driven to rotate. The specific implementation method can be adjusted accordingly according to actual needs, and is not limited here.

[0042] The second aspect of the utility model provides an embodiment of a garbage crusher, including the above transmission speed regulating mechanism. After the driving device 800 is started, the secondary shaft driving wheel 450 will be driven to move through the first transmission belt group 200, and the movement of the secondary shaft driving wheel 450 can drive the tool spindle through the second transmission belt group 300, so the driving effect of the tool spindle can be effectively achieved. In addition, since the first transmission belt group 200 and the second transmission belt group 300 jointly perform speed regulation between the driving device 800 and the tool spindle, it can also effectively ensure that the operating speed of the tool spindle is effectively adjusted. When the first transmission belt group 200 or the second transmission belt group 300 needs to be tensioned and adjusted, the position of the secondary shaft driving wheel 450 can be changed through the adjustment component 500, and the tension adjustment effect of the first transmission belt group 200 and the second transmission belt group 300 can be achieved through the position change of the secondary shaft driving wheel 450, so as to facilitate the accurate driving of the tool spindle.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
