[0025] Further, the bottom center of the chute 1 is supported by a snap ring 11, the bottom of the center snap ring 11 is fixedly connected with the top of the support rod 2, the left and right sides of the bottom of the chute 1 are slidably connected with the snap ring 11, the bottoms of the two snap rings 11 located on the left and right sides are slidably connected between the left and right sides of the support rod 2, the bottom of the support rod 2 extends into the support shell 13 and is rotatably connected therewith, the bottom of the support shell 13 is fixedly connected with the lifting plate 20, the bottom of the lifting plate 20 is provided with the base 21, the top center of the base 21 is fixedly connected with the telescopic cylinder 22, and the top telescopic end of the telescopic cylinder 22 is fixedly connected between the bottom center of the lifting plate 20.

[0026] The bottom center of the chute 1 is supported by a snap ring 11, and the snap ring 11 is directly fixed on the top of the support rod 2, which ensures that the chute 1 has a stable support point at the central position and can bear a larger vertical load. The left and right sides of the bottom of the chute 1 are provided with a slideable snap ring 11, and the snap rings 11 are slidably connected between the two sides of the support rod 2. This design allows the chute 1 to freely adjust the position within a certain range while maintaining good support. The bottom of the support rod 2 extends into the support shell 13 and is rotatably connected therewith. This design allows the entire chute 1 to rotate as needed, increasing its operational flexibility. The lifting plate 20 is located below the support shell 13 and is connected to the base 21 through the telescopic cylinder 22. The telescopic cylinder 22 can control the height change of the lifting plate 20, thereby adjusting the height of the chute 1, achieving automatic height adjustment and reducing manual intervention.

[0027] Further, the inside of the support rod 2 is provided with an installation groove 201, and a bidirectional threaded rod 3 is rotatably connected in the installation groove 201.

[0028] Further, the center surface of the bidirectional threaded rod 3 located in the installation groove 201 is fixedly sleeved with a worm gear 4, the top of the worm gear 4 is meshingly connected with a worm 5, one end of the worm 5 is rotatably connected with one side of the inner wall of the installation groove 201, and the other end of the worm 5 extends to the outside of the support rod 2 and is rotatably connected therewith.

[0029] Further, the first motor 6 is fixedly connected to one side of the outside of the support rod 2, the output shaft of the first motor 6 is fixedly connected with one end of the worm 5, the outside of the first motor 6 is provided with a protective cover 601, and one side of the protective cover 601 is fixedly connected with one side of the surface of the support rod 2.

[0030] In order to protect the first motor 6 from the external environment (such as dust, moisture, etc.), a protective cover 601 is arranged outside the first motor 6, and the protective cover 601 is fixedly connected with the surface of the support rod 2 to ensure the safe operation of the first motor 6.

[0031] When the first motor 6 is started, the first motor 6 drives the worm 5 to rotate, and the worm 5 drives the worm wheel 4 to rotate through the meshing connection with the worm wheel 4, and the rotation of the worm wheel 4 drives the bidirectional threaded rod 3 to rotate, and the rotation of the bidirectional threaded rod 3 drives the sliding clamping ring 11 to slide along the left and right sides of the support rod 2, thereby improving the support effect of the chute 1. Since the worm wheel 4 and the worm 5 are adopted, the system has self-locking property, that is, even after the first motor 6 stops working, the angle of the chute 1 can be kept unchanged, thereby improving the stability and safety of the system.

[0033] When the first motor 6 is started, the worm 5 drives the bidirectional threaded rod 3 to rotate through the worm wheel 4, and the rotation of the bidirectional threaded rod 3 drives the two threaded sleeves 7 to move towards or away from each other along the axis thereof. Since the threaded sleeves 7 are slidably connected with the horizontal limiting rod 8, they remain horizontal during the movement. The greater the distance between the two clamping rings 11, the greater the contact area between the three clamping rings 11 and the bottom of the chute 1, so as to ensure effective support for the bottom of the chute 1 and thereby ensure the stability of the device.

[0034] Further, the top of each of the two threaded sleeves 7 is rotatably connected with an inclined fixed sleeve 9, each of the two fixed sleeves 9 is slidably connected with an extension rod 10, one end of each of the two extension rods 10 away from the two fixed sleeves 9 extends to the outside of the fixed sleeve 9 and is rotatably connected with a clamping ring 11, and each of the two fixed sleeves 9 is provided with a first spring 12, one end of each of the two first springs 12 is fixedly connected with one side of the inner wall of the fixed sleeve 9, and the other end of each of the two first springs 12 is fixedly connected with one end of the extension rod 10.

[0037] Further, the bottom of the inner wall of the support shell 13 is fixedly connected with a second motor 16 in the center, and the top output shaft of the second motor 16 is fixedly connected with the bottom of the rotating shaft 15, and the rotating shaft 15 is fixedly sleeved with a ratchet wheel 17 on the surface above the fixed plate 14, and the surface of the ratchet wheel 17 is clamped with a pawl 18, and the pawl 18 is rotatably arranged on the top of the fixed plate 14, and a No. 2 spring 19 is fixedly connected between one side of the top of the fixed plate 14 and the side of the pawl 18 away from the ratchet wheel 17.

[0038] The mechanism composed of the ratchet wheel 17 and the pawl 18 ensures that the rotating shaft 15 can only rotate in one direction, preventing the chute 1 from rotating in the opposite direction under unexpected circumstances, and the No. 2 spring 19 provides a restoring force, so that the pawl 18 always maintains contact with the ratchet wheel 17, ensuring the effective operation of the ratchet wheel 17-pawl 18 mechanism.

[0039] After the second motor 16 is started, the top output shaft thereof directly drives the rotating shaft 15 to rotate, and the top of the rotating shaft 15 is fixedly connected with the bottom of the support rod 2, so that the rotation of the rotating shaft 15 causes the support rod 2 and the chute 1 to rotate as a whole around the center of the fixed plate 14, changing the direction of the chute 1. The rotating shaft 15 is fixedly sleeved with a ratchet wheel 17 on the surface above the fixed plate 14, and the surface of the ratchet wheel 17 is clamped with a pawl 18, and the pawl 18 always maintains contact with the ratchet wheel 17 through the No. 2 spring 19, ensuring that the rotating shaft 15 can only rotate in one direction, preventing the chute 1 from rotating in the opposite direction under unexpected circumstances. This design increases the safety and reliability of the system, ensuring the stability of the chute 1 in the set direction.

[0040] After the first motor 6 is started, the output shaft thereof drives the worm 5 to rotate, and the worm 5 meshes with the worm gear 4, causing the worm gear 4 to rotate, and the worm gear 4 is fixedly sleeved on the bidirectional threaded rod 3, so that the rotation of the worm gear 4 causes the bidirectional threaded rod 3 to rotate. When the bidirectional threaded rod 3 rotates, due to the opposite threads on the left and right ends thereof, the two threaded sleeves 7 will move towards or away from each other along their axes, and the horizontal limiting rod 8 ensures that the threaded sleeves 7 remain horizontal during the movement, preventing deviation. The movement of the threaded sleeves 7 drives the fixed sleeve 9 arranged obliquely to move synchronously, and the telescopic rod 10 inside the fixed sleeve 9 extends or retracts according to the angle change of the chute 1, and the elastic support force is provided by the No. 1 spring 12, and one end of the telescopic rod 10 is rotatably connected with the snap ring 11, and these snap rings 11 support the bottom of the chute 1 and automatically adjust the position according to the angle change of the chute 1, ensuring that the chute 1 always maintains stable support.

[0041] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
