Description

Technical Field

[0001] This invention relates to the field of solid waste treatment equipment technology, and specifically to a novel L-shaped screw conveyor device. Background Technology

[0002] Traditional screw conveyors are all straight. When a secondary angle adjustment is required, two screws are usually used to meet the needs. However, in some extreme cases, the screw angle may be too large, and the length of the vertical screw may not meet the requirements. Therefore, those skilled in the art have provided a novel L-shaped screw conveyor to solve the problems mentioned in the background art. Summary of the Invention

[0003] The purpose of this invention is to provide a novel L-shaped screw conveyor to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it comprises a horizontal shaft, a horizontal cylinder, a vertical shaft, a vertical cylinder, helical blades, a gearbox, a feed inlet, a discharge outlet, and a drive motor; helical blades are respectively installed on the horizontal shaft and the vertical shaft, and the horizontal shaft and the vertical shaft are connected by a gearbox, which includes a first bevel gear, a second bevel gear, a housing, a first bearing, and a second bearing; a first bevel gear is installed at one end of the horizontal shaft, and the first bevel gear meshes with the second bevel gear, the second bevel gear is installed at the bottom of the vertical shaft, the first bevel gear and the second bevel gear are located inside the housing, a first bearing is installed between the horizontal shaft and the housing, and a second bearing is installed between the vertical shaft and the housing; a horizontal cylinder is provided outside the horizontal shaft and the helical blades, and a vertical cylinder is provided outside the vertical shaft and the helical blades, the horizontal cylinder and the vertical cylinder are connected in an L-shape, a feed inlet is installed at one end of the horizontal cylinder, and a discharge outlet is installed at the upper end of the vertical cylinder, and the drive motor is connected to the horizontal shaft via a sprocket and a chain.

[0005] Furthermore, the second bearing is a tapered roller bearing.

[0006] Furthermore, double-lip skeleton oil seals are respectively installed between the first bearing and the horizontal shaft and between the second bearing and the vertical shaft.

[0007] The beneficial effects of adopting the above structure are as follows: The novel L-shaped screw conveyor of the present invention only requires one power mechanism to drive it, and can change the shaft angle by different transmission ratios. Compared with two separate screws, it reduces the cost of use and can meet the user's needs when the screw angle is too large. Attached Figure Description

Detailed Implementation

[0010] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0011] See as Figure 1 As shown, this specific embodiment adopts the following technical solution: it includes a horizontal shaft 1, a horizontal cylinder 2, a vertical shaft 3, a vertical cylinder 4, spiral blades 5, a gearbox 6, a feed inlet 7, a discharge outlet 8, and a drive motor 9; spiral blades 5 are respectively installed on the horizontal shaft 1 and the vertical shaft 3, and the horizontal shaft 1 and the vertical shaft 3 are connected by the gearbox 6, which includes a first bevel gear 61, a second bevel gear 62, a housing 63, a first bearing 64, and a second bearing 65; the first bevel gear 61 is installed at one end of the horizontal shaft 1. The first bevel gear 61 meshes with the second bevel gear 62. The second bevel gear 62 is installed at the bottom of the vertical shaft 3. The two helices are connected by bevel gears, which can change the shaft angle by different transmission ratios, so as to meet the user's needs when the angle of the helices is too large. The first bevel gear 61 and the second bevel gear 62 are located inside the housing 63. The first bearing 64 is installed between the horizontal shaft 1 and the housing 63, and the second bearing 65 is installed between the vertical shaft 3 and the housing 63. The second bearing 65 is a tapered roller bearing, which can withstand bidirectional axial force.

[0012] A horizontal cylinder 2 is provided outside the horizontal shaft 1 and the spiral blade 5, and a vertical cylinder 4 is provided outside the vertical shaft 3 and the spiral blade 5. The horizontal cylinder 2 and the vertical cylinder 4 are connected in an L-shape and the connection is welded. A feed inlet 7 is installed at one end of the horizontal cylinder 2, and the material enters through the feed inlet 7. A discharge outlet 8 is installed at the upper end of the vertical cylinder 4, and the material rises to the height of the discharge outlet 8. The drive motor 9 is connected to the horizontal shaft 1 through a sprocket and a chain, and is driven by a single power mechanism.
