[0025] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0026] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0027] Example 1

[0028] like Figure 1 As shown, this embodiment provides a material blocking prevention structure of a screw conveyor with an intermediate hanging bearing, comprising a housing 1, a hanging bearing 2, at least two spiral sections 3, and a cover plate 4;

[0029] The cross-section of the shell 1 is a U-shaped structure, and the top end of the shell 1 is open. The cover plate 4 is arranged at the top end opening of the shell 1. The two spiral sections 3 can be rotatably installed in the shell 1. The spiral sections 3 are arranged along the length direction of the shell 1, that is, the axial direction of the spiral sections 3 is parallel to the length direction of the shell 1. The hanging bearing 2 is arranged between the two spiral sections 3, and the hanging bearing 2 is fixed on the shell 1. A connecting shaft is provided in the hanging bearing 2, and the connecting shaft can rotate in the hanging bearing 2. Both ends of the connecting shaft are coaxially fixed to the two spiral sections 3, so that the two spiral sections 3 can rotate synchronously. A window is provided on the cover plate 4, and the window is located above the hanging bearing 2. A cavity structure 5 with an opening at the bottom is provided above the window, and the bottom opening of the cavity structure 5 is sealed and connected to the window.

[0030] The window is arranged axially along the spiral section 3, and the suspension bearing 2 is located at the midline of the window, so that the window can cover the front and rear sides of the suspension bearing 2 at the same time, so that the material transported by the upstream spiral section 3 can enter the cavity structure 5 through the window, and then enter the downstream spiral section 3 through the window.

[0031] Therefore, the anti-blocking structure of the screw conveyor with an intermediate hanging bearing provided in this embodiment can form a cavity above the hanging bearing 2 for material to pass through by setting the window and the cavity structure 5. When blockage occurs at the hanging bearing 2, the material can move to the other side of the hanging bearing 2 through the cavity structure 5, thereby preventing blockage.

[0032] In this embodiment, the window is a rectangular structure, the width of the window can be the same as the width of the housing 1, and the cover plate 4 can be divided into two separate parts by the window, and can be installed individually during installation. The cavity structure 5 includes an arched top plate 501 and two side plates 502, the arched top plate 501 is arranged axially along the spiral section 3, the side plates 502 are arranged vertically, and the side plates 502 are arranged axially along the spiral section 3, the arched top plate 501 and the two side plates 502 together constitute an arched structure with an opening at the bottom, the bottom opening of the arched structure is adapted to the window, and the bottom opening of the arched structure is sealed and connected to the window.

[0033] When material blockage occurs at the suspension bearing 2, the spiral section 3 can drive the material to move upward when it rotates. After the material enters the cavity structure 5 from the window, it collides with the inner wall of the arched top plate 501. At this time, the arched top plate 501 can play a guiding role, allowing the material to move downstream along the inner wall of the arched top plate 501, so that the material can move smoothly to the other side of the suspension bearing 2.

[0034] For example, if Figure 1 As shown, the side plate 502 may be an isosceles trapezoidal structure, and the arched top plate 501 may be a folded plate.

[0035] like Figure 4 As shown, the side plate 502 may be a semicircular structure, and the arched top plate 501 may be an arc-shaped plate.

[0036] The first sealing plates 503 are fixed at both ends of the arched top plate 501, and the cover plate 4 is fixed with a lap joint 6. Figure 2As shown, the lap platform 6 is located on the inner wall of the window, a second sealing plate 504 is fixed on the lap platform 6, the first sealing plate 503 and the second sealing plate 504 are fixed by bolts, and the first sealing plate 503 is lapped on the lap platform 6. The first sealing plate 503, the second sealing plate 504, and the lap platform 6 are all arranged along the width direction of the housing 1.

[0037] When installing the cavity structure 5, the first sealing plate 503 can be overlapped on the overlap platform 6 first, and the first sealing plate 503 can be aligned with the second sealing plate 504 without manually adjusting the height of the first sealing plate 503, and then the first sealing plate 503 and the second sealing plate 504 can be fixed together by bolts. The overlap platform 6 can effectively improve the sealing performance of the first sealing plate 503 and the second sealing plate 504, and at the same time improve the installation efficiency of the cavity structure 5.

[0038] like Figure 3 As shown, a third sealing plate 505 is fixed to the bottom end of the side plate 502, and a fourth sealing plate 506 is fixed to the outer wall of the shell 1. The third sealing plate 505 and the fourth sealing plate 506 are arranged along the length direction of the shell 1, and the third sealing plate 505 and the fourth sealing plate 506 are fitted and fixed.

[0039] When installing the cavity structure 5, the third sealing plate 505 can be overlapped on the fourth sealing plate 506 first, and then the third sealing plate 505 and the fourth sealing plate 506 are fixed together by bolts. The sealing performance between the cavity structure 5 and the window can be improved, and the installation efficiency of the cavity structure 5 can be improved.

[0040] A lap plate 7 is fixed on the inner wall of the housing 1, and the hanger bearing 2 is fixed to the lap plate 7 by bolts. The lap plate 7 may be an L-shaped structure, which is conducive to the rapid installation of the hanger bearing 2.

[0041] The cavity structure 5 is composed of transparent plates, that is, the arched top plate 501 and the two side plates 502 are transparent plates, which is convenient for the staff to find the blockage in time.

[0042] The anti-blocking structure of the screw conveyor with an intermediate hanging bearing provided in this embodiment also includes a motor, and the power output end of the motor is coaxially fixed with the spiral section 3, and the motor is used to drive the spiral section 3 to rotate.
