[0001] The utility model relates to the field of speed reducers, in particular to a positioning brake positioning system for a speed reducer of a biomass cutting and tearing integrated machine. Background Technique
[0002] A speed reducer plays a role in matching speeds and transmitting torques between a prime mover and a working machine or an actuator. A speed reducer is a relatively precise machine, and the purpose of using it is to reduce the speed, which is widely used in modern machinery.
[0003] The existing speed reducer follows the movement after the prime mover starts, and becomes in a free state after the prime mover stops working, and there is no limiting structure to limit it in a stable state where it cannot move. In this case, when the prime mover makes a slight rotation without receiving a control signal and not working officially, the speed reducer will also move accordingly. After the above situation occurs irregularly many times, it is extremely easy to reduce the service life of the speed reducer and affect the matching accuracy of the internal structure. Content of the Utility Model
[0004] The purpose of the utility model is to provide a positioning brake positioning system for a speed reducer of a biomass cutting and tearing integrated machine to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A positioning brake positioning system for a speed reducer of a biomass cutting and tearing integrated machine, including a machine body. One side of the machine body is provided with a brake positioning wheel fixedly connected to the output end of the speed reducer, and one end of the machine body is fixedly installed with a rotating main shaft. A rotating connecting rod is rotatably sleeved outside the rotating main shaft. One end of the rotating connecting rod is rotatably installed with a transmission connecting rod through a first connecting rod rotating shaft, and one end of the machine body is rotatably connected with a positioning rod through a positioning rod rotating shaft. The positioning rod is provided with a chute slidably adapted to a second connecting rod rotating shaft, and the end of the transmission connecting rod far from the first connecting rod rotating shaft is rotatably sleeved outside the end of the second connecting rod rotating shaft far from the positioning rod. On both sides of the brake positioning wheel, a left brake arm and a right brake arm are arranged. The rotating connecting rod and the surface of the machine body are respectively provided with a female positioning hole and a male positioning hole inserted and matched with a cylindrical positioning pin. A plurality of brake positioning grooves are opened on the outside of the brake positioning wheel and are clamped and matched with the end of the positioning rod far from the positioning rod rotating shaft.
[0006] Preferably: The number of the male positioning holes is two, and they are distributed in an arc shape along the surface of the machine body. The left brake leather and the right brake leather are respectively fixedly arranged on the inner sides of the left brake arm and the right brake arm.
[0007] Preferably: A rotating handle is fixedly installed at the end of the rotating connecting rod far from the first connecting rod rotating shaft.
[0008] Preferably, one side of the left brake arm and the right brake arm is rotatably installed on one side of the machine body through a pin shaft, and the other side of the left brake arm and the right brake arm is slidably sleeved outside the brake pull rod in the horizontal direction.
[0009] Preferably, a spring is sleeved outside the brake pull rod, and both ends of the spring are fixedly connected to the mutually approaching ends of the left brake arm and the right brake arm respectively.
[0010] Preferably, a limit block is fixedly arranged at one end of the brake pull rod located between the left brake arm and the right brake arm, and a brake handle is rotatably connected to the other end of the brake pull rod located between the left brake arm and the right brake arm in the vertical direction.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] In the shutdown state of the present utility model, the side of the positioning rod close to the brake positioning wheel is clamped and limited with the brake positioning groove of the brake positioning wheel to prevent the brake positioning wheel from rotating. At the same time, the female positioning hole of the rotating connecting rod is aligned with one of the sub-positioning holes of the machine body and is inserted and fixed through a cylindrical positioning pin. When the speed reducer works, the cylindrical positioning pin is pulled out to release the limit between the female positioning hole of the rotating connecting rod and one of the sub-positioning holes of the machine body, and the rotating handle is rotated to drive the rotating connecting rod to rotate clockwise around the second connecting rod rotating shaft, so that one end of the positioning rod close to the brake positioning wheel is disengaged from the brake positioning groove through the transmission of the transmission connecting rod. When the rotating connecting rod rotates to align the female positioning hole with another sub-positioning hole of the machine body, the cylindrical positioning pin is inserted into the female positioning hole and the other sub-positioning hole of the machine body for plugging and fixing, so that the speed reducer works normally. When the speed reducer needs to be shut down, the brake handle is rotated counterclockwise to the side away from the brake positioning wheel, and the arc structure of the brake handle squeezes one end of the left brake arm, so that the left brake arm and the right brake arm approach each other and squeeze the outside of the brake positioning wheel to make it stop rotating. The provided left brake pad and right brake pad are used to increase the friction with the outside of the brake positioning wheel during the parking process. At the same time, by rotating the rotating handle counterclockwise, the rotating connecting rod is driven to rotate counterclockwise around the rotating main shaft, so that the positioning rod approaches the brake positioning wheel through the transmission of the transmission connecting rod, and the end of the positioning rod away from the positioning rod rotating shaft is clamped with the brake positioning groove of the brake positioning wheel. At the same time, the cylindrical positioning pin is used to limit the female positioning hole of the rotating connecting rod and the sub-positioning hole of the machine body to ensure the stability of the parking process.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Embodiment 1
[0020] Please refer to Figures 1-3 , the biomass cutting and tearing integrated machine reducer positioning brake positioning system in the figure, including the body 1, a brake positioning wheel 2 fixedly connected to the output end of the reducer is arranged on one side of the body 1, and a rotating main shaft 3 is fixedly installed at one end of the body 1. A rotating connecting rod 4 is rotatably sleeved outside the rotating main shaft 3. One end of the rotating connecting rod 4 is rotatably installed with a transmission connecting rod 6 through a first connecting rod rotating shaft 5. And one end of the body 1 is rotatably connected with a positioning rod 8 through a positioning rod rotating shaft 7. The positioning rod 8 is provided with a chute slidably adapted to the second connecting rod rotating shaft 9. And the end of the transmission connecting rod 6 away from the first connecting rod rotating shaft 5 is rotatably sleeved outside the end of the second connecting rod rotating shaft 9 away from the positioning rod 8. Left and right brake arms 13 and 14 are arranged on both sides of the brake positioning wheel 2. And female and male positioning holes 11 and 12 respectively adapted to be inserted with a cylindrical positioning pin 20 are opened on the surfaces of the rotating connecting rod 4 and the body 1. A plurality of brake positioning grooves 19 adapted to be clamped with the end of the positioning rod 8 away from the positioning rod rotating shaft 7 are opened outside the brake positioning wheel 2.
[0021] In this embodiment, the number of the sub-positioning holes 12 is two, and they are distributed in an arc along the surface of the machine body 1. The left brake shoe 15 and the right brake shoe 16 are respectively and fixedly arranged on the inner sides of the left brake arm 13 and the right brake arm 14. One end of the rotating link 4 far from the first link rotating shaft 5 is fixedly installed with a rotating handle 10. One side of the left brake arm 13 and the right brake arm 14 is rotatably installed on one side of the machine body 1 through a pin shaft, and the other side of the left brake arm 13 and the right brake arm 14 is slidably sleeved on the outer side of the brake pull rod 17 in the horizontal direction. A spring is sleeved on the outer side of the brake pull rod 17, and the two ends of the spring are respectively fixedly connected with the ends of the left brake arm 13 and the right brake arm 14 close to each other. A limiting block is fixedly arranged at one end of the brake pull rod 17 located between the left brake arm 13 and the right brake arm 14, and a brake handle 18 is rotatably connected to the other end of the brake pull rod 17 located between the left brake arm 13 and the right brake arm 14 in the vertical direction. The side of the brake handle 18 close to the brake pull rod 17 is arranged in an arc structure. A plurality of brake positioning grooves 19 are evenly distributed in a ring along the outer side of the brake positioning wheel 2.
[0022] Further, in the shutdown state, the side of the positioning rod 8 close to the brake positioning wheel 2 is clamped and limited with the brake positioning groove 19 of the brake positioning wheel 2 to prevent the brake positioning wheel 2 from rotating. At the same time, the female positioning hole 11 of the rotating link 4 is aligned with one of the sub-positioning holes 12 of the machine body 1 and is inserted and fixed through a cylindrical positioning pin 20. When the speed reducer works, the cylindrical positioning pin 20 is pulled out to release the limit between the female positioning hole 11 of the rotating link 4 and one of the sub-positioning holes 12 of the machine body 1, and the rotating handle 10 is rotated to drive the rotating link 4 to rotate clockwise around the second link rotating shaft 9, so that one end of the positioning rod 8 close to the brake positioning wheel 2 is disengaged from the brake positioning groove 19 through the transmission of the transmission link 6. When the rotating link 4 rotates to align the female positioning hole 11 with the other sub-positioning hole 12 of the machine body 1, the cylindrical positioning pin 20 is inserted into the female positioning hole 11 and the other sub-positioning hole 12 of the machine body 1 for insertion and fixation, so that the speed reducer works normally. When the speed reducer needs to be shut down, the brake handle 18 is pulled counterclockwise to the side far from the brake positioning wheel 2, and the arc structure of the brake handle 18 presses one end of the left brake arm 13, so that the left brake arm 13 and the right brake arm 14 approach each other and press the outer side of the brake positioning wheel 2 to make it stop rotating. The provided left brake shoe 15 and right brake shoe 16 are used to increase the friction force with the outer side of the brake positioning wheel 2 during the parking process. At the same time, the rotating handle 10 is rotated counterclockwise to drive the rotating link 4 to rotate counterclockwise around the rotating main shaft 3, so that the positioning rod 8 approaches the brake positioning wheel 2 through the transmission of the transmission link 6, and the end of the positioning rod 8 far from the positioning rod rotating shaft 7 is clamped with the brake positioning groove 19 of the brake positioning wheel 2. At the same time, the female positioning hole 11 of the rotating link 4 and the sub-positioning hole 12 of the machine body 1 are limited by the cylindrical positioning pin 20 to ensure the stability of the parking process.
[0023] Working principle of the utility model: In the shutdown state, the side of the positioning rod 8 close to the brake positioning wheel 2 is clamped and limited with the brake positioning groove 19 of the brake positioning wheel 2 to prevent the brake positioning wheel 2 from rotating. At the same time, the female positioning hole 11 of the rotating connecting rod 4 is aligned with one of the sub-positioning holes 12 of the machine body 1 and fixed by inserting a cylindrical positioning pin 20. When the speed reducer works, the cylindrical positioning pin 20 is pulled out to release the limit between the female positioning hole 11 of the rotating connecting rod 4 and one of the sub-positioning holes 12 of the machine body 1, and the rotating handle 10 is rotated to drive the rotating connecting rod 4 to rotate clockwise around the second connecting rod rotating shaft 9. Thus, through the transmission of the transmission connecting rod 6, one end of the positioning rod 8 close to the brake positioning wheel 2 disengages from the brake positioning groove 19. When the rotating connecting rod 4 rotates to align the female positioning hole 11 with another sub-positioning hole 12 of the machine body 1, the cylindrical positioning pin 20 is inserted into the female positioning hole 11 and the other sub-positioning hole 12 of the machine body 1 for plugging and fixing, so that the speed reducer works normally. When the speed reducer needs to stop, the brake handle 18 is pulled counterclockwise to the side away from the brake positioning wheel 2, and the arc structure of the brake handle 18 squeezes one end of the left brake arm 13, so that the left brake arm 13 and the right brake arm 14 approach each other and squeeze the outside of the brake positioning wheel 2 to make it stop rotating. The left brake pad 15 and the right brake pad 16 are provided to increase the friction with the outside of the brake positioning wheel 2 during the parking process. At the same time, by rotating the rotating handle 10 counterclockwise, the rotating connecting rod 4 is driven to rotate counterclockwise around the rotating main shaft 3. Thus, through the transmission of the transmission connecting rod 6, the positioning rod 8 approaches the brake positioning wheel 2, and the end of the positioning rod 8 away from the positioning rod rotating shaft 7 is clamped with the brake positioning groove 19 of the brake positioning wheel 2. At the same time, the cylindrical positioning pin 20 limits the female positioning hole 11 of the rotating connecting rod 4 and the sub-positioning hole 12 of the machine body 1 to ensure the stability of the parking process.
