[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The utility model drives the rotating plate to rotate by the anti-collision plate, thereby changing the bottom of the hopper from a closed state to an open state. When the transport equipment is loaded with materials, the materials reach the transport equipment through the opened rotating plate. When the transport equipment is full, the rotating plate is driven back to the initial position by the reset spring, and the bottom of the hopper is closed, so that the materials are gathered in the hopper to prevent the materials from spilling on the bottom surface.

[0015] (2) When the material enters the hopper through the drop plate and torsion spring, it first falls on the drop plate to reduce the impact force, thereby preventing the impact force of the material from being too large when it falls and causing damage to the transportation equipment.

[0016] (3) When the transport equipment is docked with the scraper, the transport equipment contacts the anti-collision plate at the bottom of the rotating plate. The impact force is reduced by the buffering of the connecting rod and the buffer spring, and the transport equipment is prevented from colliding with the scraper while driving the rotating plate to rotate.

DETAILED DESCRIPTION

[0022] 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.

[0023] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a groove limiting structure of a scraper, comprising a limiting structure body 1; in order to solve the problem that materials are spilled on the ground during the gap when the transport equipment is switched, a conveying trough 2 is provided on the limiting structure body 1, and side plates 21 are installed on both sides of the conveying trough 2. A hopper 3 is installed on the side plates 21, and an opening and closing mechanism 4 is provided in the hopper 3. A material dropping mechanism 5 is provided in the opening and closing mechanism 4. The bottom of the hopper 3 is closed by the opening and closing mechanism 4, so that the material first falls on the material dropping mechanism 5 and then gathers in the hopper 3, so as to prevent the material from spilling during the time gap when the transport equipment is switched;

[0024] In order to prevent the material from spilling, the opening and closing mechanism 4 includes a rotating plate 41, which is rotatably mounted on the bottom of the hopper 3. Connectors 42 are mounted on both sides of the hopper 3, and connecting shafts 43 are mounted on the connecting shafts 43. The rotating plate 41 is rotatably mounted on the connecting shafts 43. A limiting column 44 is mounted on one side of the hopper 3, and a limiting plate 45 is mounted on the rotating plate 41. A limiting hole 46 is provided on the limiting plate 45, and the limiting column 44 is slidably mounted in the limiting hole 46. An anti-collision mechanism 6 is provided at the bottom of the rotating plate 41, and a return spring 47 is sleeved on the limit column 44. One end of the return spring 47 is mounted on one side of the hopper 3, and the other end of the return spring 47 is mounted on one side of the limit plate 45. When the transport equipment is docked with the scraper, the transport equipment and the rotating plate 41 are connected. The anti-collision plate 61 at the bottom of the movable plate 41 contacts with each other, and the impact force is reduced through the buffering of the connecting rod 62 and the buffer spring 63, so that the anti-collision plate 61 drives the rotating plate 41 to rotate, and the bottom of the hopper 3 is changed from a closed state to an open state. The material falls from the conveying trough 2 onto the blanking plate 52, and the impact force is weakened by the blanking plate 52 and the torsion spring 54. After the material enters the hopper 3, it passes through the opened rotating plate 41 and falls onto the transportation equipment. When the transportation equipment is full, the transportation equipment is separated from the anti-collision plate 61, and the rotating plate 41 rotates back to the initial position under the action of the reset spring 47, and the bottom of the hopper 3 is closed. At this time, the material falls on the blanking plate 52 to weaken the impact force, and then falls into the hopper 3, gathers in the hopper 3, and prevents the material from falling on the ground.

[0025] The working principle is as follows: when the transport equipment is docked with the scraper, the transport equipment contacts the anti-collision plate 61 at the bottom of the rotating plate 41, and the impact force is reduced through the buffering of the connecting rod 62 and the buffer spring 63, so that the anti-collision plate 61 drives the rotating plate 41 to rotate, and the bottom of the hopper 3 is changed from a closed state to an open state. The material falls from the conveying trough 2 onto the blanking plate 52, and the impact force is reduced through the blanking plate 52 and the torsion spring 54. After the material enters the hopper 3, it passes through the opened rotating plate 41 and falls onto the transport equipment. When the transport equipment is full, the transport equipment is separated from the anti-collision plate 61, and the rotating plate 41 rotates back to its initial position under the action of the reset spring 47, closing the bottom of the hopper 3. At this time, the material falls on the blanking plate 52 to reduce the impact force, and then falls into the hopper 3, gathers in the hopper 3, and prevents the material from falling on the ground.

[0026] Example 2: Figure 2 and Figure 3In order to prevent the impact force of the material from being too strong when it falls, the blanking mechanism 5 includes a transverse axis 51, which is installed in the hopper 3. A blanking plate 52 is rotatably installed on the transverse axis 51. A transverse axis hole 53 is opened on the blanking plate 52. The transverse axis 51 is installed in the transverse axis hole 53. A torsion spring 54 is installed in the transverse axis hole 53. One end of the torsion spring 54 is installed on the transverse axis 51, and the other end of the torsion spring 54 is installed on the inner wall of the transverse axis hole 53. The material falls from the conveying trough 2 onto the blanking plate 52, and the impact force is weakened by the blanking plate 52 and the torsion spring 54, and the material enters the hopper 3. The remaining features are the same as those in Example 1.

[0027] Example 3: Figure 2 and Figure 3 In order to prevent the transportation equipment from colliding with the scraper when docking, the anti-collision mechanism 6 includes an anti-collision plate 61, which is installed at the bottom of the rotating plate 41. A connecting rod 62 is installed on one side of the anti-collision plate 61, and the connecting rod 62 is slidably installed on the rotating plate 41. A buffer spring 63 is sleeved on the connecting rod 62, one end of the buffer spring 63 is installed on the anti-collision plate 61, and the other end of the buffer spring 63 is installed on the rotating plate 41. When the transportation equipment is docked with the scraper, the transportation equipment contacts the anti-collision plate 61 at the bottom of the rotating plate 41. The buffering of the connecting rod 62 and the buffer spring 63 reduces the impact force, so that the anti-collision plate 61 drives the rotating plate 41 to rotate, and the bottom of the hopper 3 is changed from a closed state to an open state. The remaining features are the same as those in Example 1.
