Therefore, it is inconvenient to accurately adjust the position of the grinding disc. After long-term use, wear will occur between the grinding disc and the rotary cutter, resulting in the grinding disc and the rotary cutter cannot fit closely. This results in the grinding disc being unable to effectively grind the rotary cutter when grinding the rotary cutter, thereby affecting the grinding effect of the rotary cutter.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 The utility model provides a technical solution: a grinding device for rotary blade production of a rotary tiller, comprising: a base 1 and two grinding discs 7, a transverse driving mechanism 2 is installed in the groove on the top of the base 1, a support frame 3 is installed on the top of the transverse driving mechanism 2, a longitudinal driving mechanism 4 is installed on the top of the support frame 3, a movable frame 5 is installed in the middle of the support frame 3, two fixed frames 6 are relatively arranged at the bottom of the movable frame 5, and two grinding discs 7 are respectively installed on the opposite surfaces of the two fixed frames 6;

[0023] The input shaft of the grinding disc 7 is connected to a transmission belt 8 through a pulley, and the end of the transmission belt 8 away from the input shaft of the grinding disc 7 is connected to a transmission shaft 9, and bumps 10 are installed all around the transmission shaft 9. The ends of the two sets of transmission shafts 9 close to each other are connected to a rotating shaft 11, and the outer side of the rotating shaft 11 is connected to a bevel gear A, and the top of the bevel gear A is meshed and connected to a bevel gear B, and the axis of the bevel gear B is connected to a connecting shaft 12, and the top of the connecting shaft 12 is connected to a transmission motor 13 through a coupling. The outer side of the transmission shaft 9 is also connected to a connecting block 14 through a bearing, and both sides of the connecting block 14 are provided with fixed blocks 15 fixed to the outer side of the transmission shaft 9. The side of the connecting block 14 away from the transmission shaft 9 is connected to the fixed frame 6, and a connecting rod 16 that passes through the movable frame 5 is installed on one side of the fixed frame 6. A screw 17 is connected to one side of the connecting rod 16, and a guide block 18 is installed on the outer side of the screw 17. The screw 17 and the guide block 18 are threadedly connected. The guide block 18 is installed on the top of the movable frame 5, and the screw 17 is connected to the connecting rod 16 through a bearing. Two groups of connecting rods 16 are installed symmetrically about the center line of the movable frame 5, and the connecting rod 16 is an "L"-shaped structure.

[0024] In specific implementation, the grinding device for the rotary blade production of the rotary tiller can rotate the screw 17 when the position of the grinding disc 7 needs to be adjusted. Since the screw 17 is threadedly connected to the guide block 18, and the screw 17 is connected to the connecting rod 16 through a bearing, and the connecting rod 16 passes through the slide groove of the movable frame 5 and is connected to the fixed frame 6, when the screw 17 is rotated, the fixed frame 6 will be driven to move with the cooperation of the guide block 18, and the grinding disc 7 is installed on the other side of the fixed frame 6, so the fixed frame 6 will drive the grinding disc 7 to move synchronously;

[0025] When the fixed frame 6 moves, it will drive the connecting block 14 on one side to move. When the connecting block 14 moves, it will drive the transmission shaft 9 to extend and retract along the rotating shaft 11 under the action of the fixed blocks 15 on both sides of the transmission shaft 9. At the same time, the transmission shaft 9 will extend and retract normally along the rotating shaft 11 through the protrusions 10 around it. When the transmission shaft 9 extends and retracts, the pulley will drive the transmission belt 8 to move synchronously.

[0026] When the rotary cutter is to be polished, it is only necessary to start the transmission motor 13, and the transmission motor 13 will drive the bevel gear A and the bevel gear B to rotate through the connecting shaft 12. At the same time, with the cooperation of the bevel gear A and the bevel gear B, the rotating shaft 11 will rotate, and the transmission shaft 9 is connected to the slide grooves at both ends of the rotating shaft 11 through the protrusions 10. When the rotating shaft 11 rotates, the force of the slide grooves and the protrusions 10 will cause the transmission shaft 9 to rotate synchronously, and then cooperate with the transmission belt 8 and the pulley to drive the grinding disc 7 on one side of the fixed frame 6 to rotate, so as not to affect the normal rotation of the grinding disc 7.

[0027] See also Figure 1 , Figure 3 and Figure 4 It can be seen that when in use, the screw 17 can be rotated according to the use requirements, so that the screw 17 drives the fixed frame 6 and the grinding disc 7 to move through the connecting rod 16 and the guide block 18, and the rotating shaft 11 can drive the transmission shaft 9 to rotate through the protrusion 10 connected between the transmission shaft 9 and the rotating shaft 11, and then cooperate with the transmission belt 8 and the pulley to drive the grinding disc 7 to rotate, so as to facilitate the adjustment of the position of the grinding disc 7 without affecting the normal rotation of the grinding disc 7.

[0028] A slag discharge port 19 is provided at the top of the base 1, and a clamp 20 is slidably connected to the inside of the slag discharge port 19. A push plate 21 is slidably connected to the top of the base 1 through a slide groove, and a connecting rod 22 is connected between two groups of push plates 21. A waste box 23 is provided at the bottom of the slag discharge port 19, and sliding blocks 24 are provided between the two sides of the waste box 23 and the slide groove of the base 1. The waste box 23 forms a sliding structure with the base 1 through the sliding blocks 24, and two groups of push plates 21 are symmetrically provided about the center line of the slag discharge port 19.

[0029] During specific implementation, the grinding device for the production of the rotary tiller blade can push the connecting rod 22 when it is necessary to clean the waste residue on the top of the base 1. Since both ends of the connecting rod 22 are connected to two sets of push plates 21, and the bottom of the push plate 21 is slidably connected to the slide groove on the top of the base 1, when the connecting rod 22 is pushed in the direction of the slag discharge port 19, the push plate 21 can be moved in the direction of the slag discharge port 19. At this time, the push plate 21 can push the debris and waste residue on the top of the base 1 into the slag discharge port 19, and then fall into the waste box 23 inside the base 1 through the slag discharge port 19, so that the debris and waste residue generated by the grinding rotary blade can be collected and cleaned. When the debris and waste residue in the waste box 23 is full, the waste box 23 can be slid and pulled out from the inside of the base 1 by the sliding block 24, so as to facilitate the removal of the waste residue inside the waste box 23.

[0030] See also Figure 1 and Figure 2 It can be seen that when in use, the connecting rod 22 can be pushed according to the use requirements, so that the connecting rod 22 pushes the push plate 21 to move. When the push plate 21 moves, the waste slag on the top of the base 1 can be pushed into the waste box 23 through the slag discharge port 19, thereby facilitating the collection and cleaning of the waste slag.

[0031] To sum up: when the rotary tiller blade production grinding device is in use, the rotary blade to be ground can be placed between two sets of clamps 20, and the clamps 20 are composed of two sets of clamps, threaded rods and threaded blocks. By rotating the threaded rods, the clamps can slide along the slag discharge port 19, so that the rotary blade to be ground can be clamped, and then the transmission motor 13 can be started. The transmission motor 13 will drive the grinding disc 7 to rotate through the bevel gear A, bevel gear B, rotating shaft 11, transmission shaft 9 and transmission belt 8, and then start the longitudinal drive mechanism 4 and the transverse drive mechanism 2. The longitudinal drive mechanism 4 is composed of a screw rod, a motor and a screw sleeve. The screw rod is installed in the support frame 3, and the screw sleeve is connected to the movable One side of the movable frame 5, and the other side of the movable frame 5 is slidably connected to the other side of the supporting frame 3. Therefore, when the longitudinal driving mechanism 4 is working, it will drive the grinding disc 7 to move up and down through the movable frame 5, and the transverse driving mechanism 2 is composed of a screw and a screw sleeve, the screw sleeve is installed at the bottom of the supporting frame 3, and the bottom of the other side of the supporting frame 3 is slidably connected to the smooth rod of the base 1. Therefore, when the transverse driving mechanism 2 is working, it will drive the grinding disc 7 to move back and forth, and the rotary cutter of the rotary tiller can be ground by the front and back and up and down movement of the grinding disc 7. This is the use feature of the grinding device for the production of rotary cutters of rotary tillers. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
