Technical Field
[0001] The present application relates to the field of shredders, and in particular to a reducer connecting device. Background Art
[0002] In shredders, a motor is often used as the driving mechanism. This motor drives the shredder's main shaft, which in turn causes the cutter disc on the main shaft to shred the material. The motor's output shaft rotates at a high speed, necessitating the use of a speed reducer for variable speed transmission. This allows the shredder's main shaft to rotate at a low speed, allowing the cutter disc to rotate slowly and cut the material.
[0003] The relevant reducer installation structure includes a machine body, a main shaft and a reducer. The main shaft is rotatably connected to the machine body. A coupling is provided at the end of the main shaft. The coupling coaxially connects the main shaft and the output shaft of the reducer. A base is provided on the reducer. The base is used to fix the housing of the reducer so that the base can be fixed on the machine body. The base can be formed by welding metal plates. One end of the base is fixed on the reducer housing, and the other end is fixed on the machine body.
[0004] The above-mentioned related technical solutions have the following defects: the reducer is prone to vibration during operation, and the base has a poor supporting effect on the reducer. Utility Model Content
[0005] In order to improve the stability of the reducer installed on the machine body, the present application provides a reducer connecting device.
[0006] The present application provides a reducer connection device that adopts the following technical solution:
[0007] A reducer connecting device includes a machine body, a main shaft, a reducer and a connecting mechanism. The main shaft is rotatably connected to the machine body, the reducer is arranged outside the machine body and is transmission-connected to the main shaft, the connecting mechanism is arranged as a cylindrical structure, the connecting mechanism is sleeved outside the main shaft and the reducer output shaft, one end of the connecting mechanism is fixed to the machine body, and the other end is fixed to the reducer.
[0008] By adopting the above technical solution and arranging the main shaft and reducer on the machine body, the user can connect the drive shaft to the input shaft of the reducer, and the drive shaft drives the input shaft of the reducer to rotate. There are multiple sets of gear sets in the reducer, so that the output shaft of the reducer rotates at a low speed and drives the main shaft to rotate. In the process of the drive shaft driving the reducer to rotate, the connecting mechanism plays a supporting role. The cylinder of the connecting mechanism is coaxially arranged with the main shaft, which has the effect of uniformly supporting the reducer and reducing the chance of shaking on the reducer. The connecting mechanism cover is arranged outside the main shaft and the output shaft of the reducer, thereby reducing the entanglement of debris on the rotating main shaft and the output shaft of the reducer, thereby improving the safety of use.
[0009] Optionally, the machine body includes a lower shaft seat, an end cover and multiple outer frames, the end cover is detachably connected to the lower shaft seat, the main shaft is rotatably connected between the lower shaft seat and the end cover, the outer frame is fixed to the end of the lower shaft seat, and the outer frame is arranged on one side of the main shaft.
[0010] By adopting the above technical solution, semicircular arcs are respectively provided on the lower shaft seat and the end cover. When the lower shaft seat and the end cover are connected, the semicircular arcs on the lower shaft seat and the end cover are assembled into a circular hole structure. The main shaft can be set in the circular hole, which makes it convenient for the user to install the main shaft on the machine body. By providing an outer frame on one side of the main shaft, the outer frame plays the effect of separating the cutter disc on the main shaft, which can reduce the chance of the user accidentally touching the rotating cutter disc and improve the safety of use.
[0011] Optionally, a plurality of guide plates are provided on the outer frame, and the plurality of guide plates are arranged at equal intervals along the length direction of the main shaft, and an inclined surface is provided on the upper side of the guide plates, and the inclined direction of the guide plates points to the main shaft.

By opening a slope on the guide plate, the upper side of the slope is set higher than the cutter disc, and the lower side of the slope is flush with the main shaft. When the user pours the material into the machine body, the material can fall along the slope of the guide plate into the position between the two main shafts. At this time, the cutter discs on the two main shafts cut the material at the same time, which can improve the cutting effect.
[0013] Optionally, an arc-shaped groove is provided on one end of the guide plate close to the main shaft, and a plurality of convex circles are provided on the main shaft.

[0018] By adopting the above technical solution, flanges are provided at both ends of the connecting mechanism, so that the connecting mechanism can be fixed between the machine body and the reducer through the flanges. The user can remove the bolts on flange one or flange two respectively to pull out the connecting shaft or coupling from the connecting mechanism, thereby facilitating maintenance.
[0019] Optionally, the connecting mechanism is provided with a plurality of through holes, and each through hole is connected to a pipe.
[0020] By adopting the above technical solution, by opening a through hole on the connecting mechanism, the user can pass low-temperature gas into the connecting mechanism through the pipeline, so that the low-temperature gas can reduce the temperature on the connecting shaft and the coupling, reducing the chance of the connecting shaft and the coupling being deformed due to heat.
[0021] Optionally, liquid is introduced into the connecting mechanism through a pipeline.
[0022] By adopting the above technical solution, the user introduces lubricating oil into the connection mechanism to reduce the wear between the coupling and the connecting shaft. Rubber sealing rings and other parts can be set on flange one and flange two to improve the sealing performance of the end of the connection mechanism.
[0023] In summary, the beneficial technical effects of this application are:
[0024] 1. By arranging the main shaft and reducer on the machine body, the user can connect the drive shaft to the input shaft of the reducer, and the drive shaft drives the input shaft of the reducer to rotate. Multiple sets of gear sets are arranged in the reducer, so that the output shaft of the reducer rotates at a low speed and drives the main shaft to rotate. In the process of the drive shaft driving the reducer to rotate, the connecting mechanism plays a supporting role. The cylinder of the connecting mechanism is coaxially arranged with the main shaft, which has the effect of uniformly supporting the reducer and reducing the chance of shaking on the reducer. The connecting mechanism cover is arranged outside the main shaft and the output shaft of the reducer, thereby reducing the entanglement of debris on the rotating main shaft and the output shaft of the reducer, thereby improving the safety of use;
[0025] 2. By providing multiple guide plates on the outer frame, the guide plates can be spaced between adjacent cutter discs on the main shaft. By providing an inclined surface on the guide plate, the upper side of the inclined surface is higher than the cutter disc, and the lower side of the inclined surface is flush with the main shaft. When the user pours the material into the machine body, the material can fall along the inclined surface of the guide plate into the position between the two main shafts. At this time, the cutter discs on the two main shafts cut the material simultaneously, which can improve the cutting effect.
[0026] 3. By opening an arc groove on the guide plate, the cam on the main shaft can be embedded in the arc groove. When the main shaft drives the cam to rotate, the cam can rotate in the arc groove. The guide plate abuts against the main shaft through the arc groove, which supports the main shaft and reduces the chance of stress concentration and deformation on the main shaft.

[0035] The present application is further described in detail below with reference to the accompanying drawings.
[0036] The embodiment of the present application discloses a reducer connecting device, referring to Figure 1 and Figure 2, including a body 1, a main shaft 2, a reducer 3 and a connecting mechanism 4. The body 1 is used to install the main shaft 2. The main shaft 2 is set as two. The two main shafts 2 are rotatably connected to the body 1. The length directions of the main shafts 2 are parallel to each other. Both main shafts 2 are provided with multiple cutter discs, and the cutter discs on the two main shafts 2 are staggered with each other. The reducer 3 is fixed to the body 1. The reducer 3 is coaxially connected to the end of one main shaft 2. The reducer 3 is connected to the driving mechanism. The driving mechanism outputs torque. The reducer 3 can reduce the speed output by the driving mechanism and drive the main shaft 2 to rotate at a low speed, so that the cutter disc on the main shaft 2 can rotate and tear the material. The connecting mechanism 4 is sleeved at the connection between the main shaft 2 and the reducer 3. One end of the connecting mechanism 4 is fixed to the body 1, and the other end is fixed to the reducer 3. The connecting mechanism 4 serves to connect the body 1 and the reducer 3.
[0037] Reference Figure 1 and Figure 7 The connecting mechanism 4 is a cylindrical structure, with flange 1 41 and flange 2 42 fixed at both ends of the connecting mechanism 4 respectively. Flange 1 41 is detachably connected to the body 1, and flange 2 42 is detachably connected to the reducer 3. The user can disconnect the body 1 and the reducer 3 by removing flange 1 41 or flange 2 42. After disconnection, the connecting mechanism 4 is respectively located on the reducer 3 or the body 1, so that the user can conveniently select the disassembly position according to the position required for maintenance.
[0038] Reference Figure 3 and Figure 4 The machine body 1 includes a lower shaft seat 11, an end cover 12, and two outer frames 13. The outer frames 13 are arranged on both sides of the lower shaft seat 11. A semi-circular groove is opened on the lower shaft seat 11, and a semi-circular groove is opened on the end cover 12. The end cover 12 and the lower shaft seat 11 are detachably connected by bolts. When the end cover 12 is connected to the lower shaft seat 11, the semi-circular grooves on the lower shaft seat 11 and the end cover 12 correspond to each other and form a circular hole for mounting the main shaft 2. When the main shaft 2 is rotatably connected to the lower shaft seat 11 and the end cover 12, the main shaft 2 is located between the two outer frames 13. The outer frame 13 blocks the side of the cutter head on the main shaft 2, which can reduce the chance of the cutter head scratching the user.
[0039] Reference Figure 4 Multiple guide plates 14 are provided on the side of the outer frame 13 near the main shaft 2. These flat plates are arranged at equal intervals along the length of the main shaft 2. When the cutter discs are installed on the main shaft 2 at equal intervals along its length, they are positioned between two adjacent guide plates 14. The upper sides of the guide plates 14 are provided with inclined surfaces that point toward the main shaft 2. When a user pours material into the machine body 1, the material slides through the guide plates 14 to the position between the two main shafts 2. At this point, the cutter discs on both main shafts 2 can shred the material, improving the crushing quality.
[0040] Reference Figure 3 and Figure 4 The spindle 2 is equipped with multiple cams 22, which are coaxially mounted on the spindle 2 and spaced evenly along its length. The cutterhead is positioned between two adjacent cams 22. The guide plate 14 has an arcuate groove 141 on the side closest to the spindle 2, with the cams 22 engaging with the grooves 141. As the spindle 2 rotates, the cams 22 abut against the grooves 141 and rotate, keeping the spindle 2 stable via the guide plate 14, thus reducing the chance of spindle 2 shaking.
[0041] Reference Figure 5 and Figure 6 The end of the main shaft 2 is coaxially connected to the connecting shaft 21. The cross-section of the connecting shaft 21 is in the shape of a gear. A coupling 31 is provided on the transmission shaft of the reducer 3. The coupling 31 is a cylindrical structure with a tooth groove on the inner wall of the cylinder. The connecting shaft 21 can be inserted into the coupling 31. At this time, the tooth groove on the inner wall of the coupling 31 is engaged with the gear on the outer wall of the connecting shaft 21.
[0042] Reference Figure 7 The connecting mechanism 4 has a plurality of through-holes in the middle, each of which is provided with a conduit 43 for fluid to enter and exit the connecting mechanism 4. The conduit 43 can be connected to an air pump, which can introduce low-temperature gas into the connecting mechanism 4, thereby maintaining a low temperature at the connection point between the connecting shaft 21 and the coupling 31 in the connecting mechanism 4, thereby reducing the probability of deformation of the connecting shaft 21 and the coupling 31 due to high temperature. In other embodiments, the user can introduce lubricating oil into the connecting mechanism 4 through the conduit 43, thereby reducing wear between the connecting shaft 21 and the coupling 31.
[0043] The implementation principle of the embodiment of the present application is: by arranging the main shaft 2 on the body 1, the main shaft 2 is connected to the reducer 3 in transmission, the driving mechanism can drive the input shaft of the reducer 3 to rotate, and the output shaft of the reducer 3 outputs power with a lower speed and drives the main shaft 2 to rotate at a low speed. By arranging a connecting mechanism 4 between the body 1 and the reducer 3, the connecting mechanism 4 is coaxially sleeved outside the connecting shaft 21 and the coupling 31, so that the connecting mechanism 4 plays the effect of supporting and fixing the reducer 3. The user can remove flange 1 41 or flange 2 42 to expose the connecting shaft 21 or the coupling 31 from the connecting mechanism 4, respectively, for easy maintenance.
[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
