[0003] When the stepped material collecting hopper is used, although the multiple steps realize the buffering of the material, the inclination of the outer surface of each step is difficult to adjust, when different physical properties of the material are transported, for the material with large particles and good fluidity, the large step inclination can make it slide smoothly, and for the material with large humidity and high viscosity, the small inclination can prevent the material from caking or blocking when it slides quickly on the step due to mutual extrusion, at the same time, the fixed step surface inclination is difficult to adjust the residence time and buffering distance of the material on the step, for example, for the material with large impact force, reducing the inclination can increase the residence time of the material on the step, so that its kinetic energy is more fully consumed, thereby better buffering effect.

[0024] It should be noted that: by adjusting the setting of the assembly, the inclination of the inclined plate 2 changes under the cooperation of the driving assembly and the connecting assembly, so that the adjustment of the material buffering effect and the adaptation to the conveying of different physical properties of the material are realized under the change of the inclination of the inclined plate 2, thereby improving the flexibility of the stepped receiving hopper for material conveying.

[0025] Please refer to Figure 5 , the connecting assembly in the drawing includes a dovetail groove 501 opened on one side of the inclined plate 2 close to the adjusting plate 402, the dovetail groove 501 is slidably connected with a dovetail plate 502, one end of the dovetail plate 502 is connected with the second fixed plate 403;

[0026] It should be noted that: through the setting of the connecting assembly, the straight plate 3 can change the inclination of the inclined plate 2 while keeping in contact with the inner wall of the receiving pipe 101 during movement.

[0027] Please refer to Figure 3 and Figure 4 , the driving assembly in the drawing includes a driving plate 601 slidably connected between the step plate 103 and the straight plate 3, the driving plate 601 is provided with a buffer member close to the straight plate 3 for buffering the material, the driving plate 601 is rotatably connected with a threaded rod 602 away from the straight plate 3, the threaded rod 602 is threadedly connected to the step plate 103, one end of the threaded rod 602 away from the driving plate 601 is located outside the receiving pipe 101 and is fixedly connected with a hand wheel 603;

[0028] It should be noted that: through the setting of the driving assembly, the inclination of the inclined plate 2 changes.

[0029] Please refer to Figure 3 and Figure 4 , the step plate 103 is provided with a guide assembly for guiding the movement of the driving plate 601, the guide assembly includes two T-shaped rods 701 slidably connected to the step plate 103, the two T-shaped rods 701 are symmetrically arranged about the threaded rod 602, one end of the two T-shaped rods 701 is connected with the driving plate 601;

[0030] It should be noted that: through the setting of the guide assembly, the movement of the driving plate 601 is guided and limited.

[0031] Please refer to Figure 3 and Figure 4 , the sidewalls of the two T-shaped rods 701 are provided with a plurality of scale lines 702;

[0032] It should be noted that: through the setting of the scale lines 702, numerical reference is provided for the inclination angle adjustment of the inclined plate 2.

[0033] Working principle: during the conveying process of the material, the material falls from a high place into the feeding pipe 102 and flows into the collecting pipe 101. First, the material impacts on the inclined plate 2 on one side of the first step plate 103. Due to the blocking of the inclined plate 2, the falling speed of the material is slowed down, and part of the kinetic energy is consumed. Then, the material flows along the surface of the inclined plate 2 to a lower inclined plate 2. In this process, the speed of the material is further reduced. As the material flows between the inclined plates 2 in turn, its kinetic energy is gradually dispersed and consumed. Finally, the material reaches the bottom of the collecting pipe 101 with a relatively low speed and a small impact force, and is discharged through the discharge port. Therefore, the stepped structure design effectively plays a role in buffering the material, reducing the impact of the material on the bottom of the collecting hopper and the surrounding equipment.

[0034] During use, when different physical properties of the material are conveyed or the buffering effect of the material is adjusted, the handle 603 can be rotated to drive the threaded rod 602 to rotate, and then the driving plate 601 is moved under the threaded engagement transmission action of the threaded rod 602 and the step plate 103 and the guiding action of the guide assembly. In turn, the straight plate 3 on one side of the inclined plate 2 is moved. During the movement of the straight plate 3, the straight plate 3 can be kept in contact with the inner wall of the collecting pipe 101 while the inclination of the inclined plate 2 is changed under the adjusting rotation action of the adjusting assembly through the connecting action of the connecting assembly. Therefore, the adjustment of the buffering effect of the material and the adaptation to the conveying of different physical properties of the material are realized under the change of the inclination of the inclined plate 2, thereby improving the flexibility of the stepped collecting hopper for material conveying.

[0035] Example 2

[0036] Please refer to Figure 4 The present embodiment further illustrates example 1. The buffer in the diagram is a shock absorber 8. The shock absorber 8 is equidistantly arranged. The two ends of each shock absorber 8 are connected to the driving plate 601 and the straight plate 3, respectively.

[0037] It should be noted that: through the arrangement of the buffer, the multiple equidistantly arranged shock absorbers 8 can be used to provide further buffering effect for the material, thereby reducing the impact force of the material.

[0038] It is worth noting that the shock absorber 8 of the present application is a spring-damping shock absorber, mainly composed of spring elements, damping elements, connecting components and housings, the spring elements usually adopt coil springs or disc springs, responsible for providing elastic support, buffering vibration and impact, storing and releasing energy through their own expansion and contraction deformation, the damping elements are generally viscous dampers or friction dampers, the viscous damper consumes energy by using the viscous resistance generated by the flow of liquid in small holes or gaps, the connecting components are used to connect the spring and damping elements together, and are connected with the equipment or structure that needs to be damped, to ensure the effective transmission of force, and the housing plays the role of protecting the internal elements, fixing structure and dustproof and waterproof.

[0039] When the external vibration or impact acts on the spring-damping shock absorber, the spring element first deforms elastically, buffers most of the impact force, and converts the kinetic energy of vibration into the elastic potential energy of the spring, at the same time, the damping element starts to work, converts part of the energy in the spring deformation process into heat energy or other forms of energy dissipation, so that under the synergistic action of the spring and the damping, the amplitude of vibration gradually decreases, achieving the effect of buffering.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
