There are multiple tooth blocks 10 that are evenly distributed on the side of the connecting tube 9 close to the worm gear 8. An internal gear 11 is provided on the front side of the tooth block 10. The inner wall of the internal gear 11 is slidably connected to the surface of the connecting tube 9. When the internal gear 11 moves backward, it can engage with the tooth block 10, thereby utilizing the rotational kinetic energy of the worm gear 8 to drive the internal gear 11 to rotate. A control mechanism is provided on the front side of the internal gear 11.

[0023] As a technical optimization solution of the present invention, the provision of a clutch mechanism allows the internal gear 11 to flexibly engage and disengage with the tooth block 10 on the front of the worm gear 8, thereby achieving precise control of the rotation of the rotary valve 4. This design not only improves the flexibility of the equipment, but also ensures the stability and reliability of the transmission.

[0024] refer to Figure 4The control mechanism comprises a connecting block 12 fixedly connected to the surface of the internal gear 11, the connecting block 12 has six and is uniformly distributed on the outer side of the internal gear 11, the inner wall of the connecting block 12 is slidably connected with a sliding block 13, the inner side of the sliding block 13 is fixedly connected to the surface of the rotary valve 4, the back surface of the sliding block 13 is fixedly connected with a tension spring 14, the back surface of the tension spring 14 is fixedly connected to the back side of the inner wall of the connecting block 12, the tension spring 14 drives the internal gear 11 to always keep on the front side of the tooth block 10 by pulling the connecting block 12, and when the connecting block 12 moves to the back side, the sliding block 13 can slide to the back side on the surface of the sliding block 13, so as to drive the internal gear 11 to move to the back side on the surface of the connecting cylinder 9 and mesh with the tooth block 10.

[0025] As a technical optimization scheme of the utility model, through the cooperation of the connecting block 12, the sliding block 13 and the tension spring 14, the accurate control of the position of the internal gear 11 is realized. When the internal gear 11 needs to mesh with the tooth block 10, the connecting block 12 can be moved backward through external force (such as pulling the handle 16). This design not only simplifies the operation process, but also improves the reliability and durability of the equipment.

[0026] Reference Figure 2 The front side of the inner side of the connecting block 12 is fixedly connected with a fixed disc 15, the front surface of the fixed disc 15 is movably connected with a pulling handle 16 through a bearing, and the pulling handle 16 cooperates with the fixed disc 15 to pull the connecting block 12, so that the connecting block 12 can move forward and backward.

The user can easily control the meshing and separation of the internal gear 11 and the tooth block 10 by pulling the handle 16, thereby improving the operation convenience and user experience of the equipment.

[0028] Reference Figure 3 The front surface of the internal gear 11 is movably connected with a limiting ring 17, and the inner wall of the limiting ring 17 is fixedly connected to the surface of the connecting cylinder 9.

[0029] As a technical optimization scheme of the utility model, the setting of the limiting ring 17 ensures the stability of the internal gear 11 during rotation. It limits the axial movement range of the internal gear 11, prevents the transmission failure or damage caused by excessive movement. This design not only improves the reliability of the equipment, but also prolongs the service life of the equipment.

[0030] Reference Figure 3 The top end of the worm 7 is movably connected with a supporting block 18 through a bearing, and the back surface of the supporting block 18 is fixedly connected to the front surface of the supporting plate 5.

[0031] As a technical optimization scheme of the utility model, the stability of the worm 7 in the rotating process is ensured through the setting of the supporting block 18. It is movably connected with the top of the worm 7 through a bearing and is fixedly connected to the front face of the supporting plate 5. This design not only improves the stability of the rotation of the worm 7, but also reduces the transmission error and wear caused by vibration.

[0032] The working principle and use process of the utility model: when in use, the transmission motor 6 is started, and the top output end drives the worm 7 to rotate through the shaft coupling. The worm 7 is engaged with the worm wheel 8, so the rotation of the worm 7 will drive the worm wheel 8 to rotate on the surface of the shaft 3. The front face of the worm wheel 8 is provided with a clutch mechanism, when it is needed to drive other components by using the rotational kinetic energy of the worm wheel 8, the clutch mechanism is operated by the control mechanism, so that the internal gear 11 is engaged with the tooth block 10 on the front face of the worm wheel 8. In this way, the rotation of the worm wheel 8 will be transmitted to the internal gear 11, and then other components (such as the rotary valve 4) connected with the internal gear 11 are driven to rotate. When it is needed to disconnect this transmission, the internal gear 11 can be separated from the tooth block 10 by reversing the operation of the clutch mechanism through the control mechanism. In addition, by pulling the handle 16 and the fixed disc 15, the connecting block 12 can be conveniently moved forward and backward, so as to control the engagement and separation of the internal gear 11 and the tooth block 10. In this way, the driving device can be used for driving while the manual operation ability is not affected, so that the overall device has the performance of fast rotation without losing the stability of manual operation. The existing paver 1 does not have an additional clutch mechanism, which avoids the time-consuming and labor-consuming manual operation of the rotary valve 4, and has the advantage of convenient use.

[0033] In summary: when in use, under the action of the driving mechanism, the clutch mechanism and the control mechanism thereof, the rotary valve 4 of the paver 1 can be electrically driven, the existing paver 1 does not have an additional clutch mechanism, which avoids the time-consuming and labor-consuming manual operation of the rotary valve 4, and has the advantage of convenient use, and solves the problem of inconvenient use.
