Description

Technical Field

[0001] The utility model relates to the technical field of screw conveying equipment, in particular to a screw conveyor. Background Art

[0002] Screw conveyor is a machine that uses a motor to drive the screw to rotate and push materials to achieve the purpose of conveying. It can convey horizontally, inclined or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. However, the existing screw conveyor has the following disadvantages:

[0003] When the screw conveyor is in use, the friction between the material and the conveying pipe and the spiral blades will cause the material to break and the machine slot and the spiral blades to wear. However, the spiral blades of the existing closed screw conveyor are inconvenient to remove from the conveying pipe (machine slot), which is not conducive to the repair of the spiral blades. Secondly, the screw conveyor is sensitive to overload and requires uniform feeding, otherwise it may cause blockage. However, the bottom of the hopper of the current screw conveyor is directly connected to the conveying pipe. After the material enters the hopper, it falls directly into the conveying pipe, resulting in frequent blockages. Therefore, the utility model proposes a screw conveyor. Utility Model Content

[0021] 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 of 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.

[0022] like Figure 1-Figure 4 As shown, it relates to a screw conveyor, including a support platform 1, a conveying pipe 2 is fixed on the upper surface of the support platform 1, and one end of the conveying pipe 2 is open, a transverse axis 3 is provided inside the conveying pipe 2, and a first spiral blade 4 is fixed on the surface of the transverse axis 3, the first spiral blade 4 is in contact with the inner wall of the conveying pipe 2, and a through hole is provided on the side wall of the conveying pipe 2 away from the open end, a first motor 5 is fixed on the upper surface of the support platform 1 and close to the through hole, a driving shaft 6 is fixedly connected to the output end of the first motor 5, a clamping assembly is provided at the other end of the driving shaft 6, the transverse axis 3 passes through the through hole and is fixedly connected to the driving shaft 6 through the clamping assembly, a feeding pipe 7 is fixedly connected to the top wall of the conveying pipe 2 close to the first motor 5, and a hopper 8 is fixedly connected to the top of the feeding pipe 7, and a feeding assembly 9 is provided inside the feeding pipe 7 and the hopper 8.

[0023] like Figure 1-Figure 3 As shown, a slot 31 is provided at one end of the transverse axis 3 close to the driving shaft 6, a latch hole 32 is provided on the side wall of the slot 31, one end of the driving shaft 6 installed with a latch assembly is inserted into the slot 31, the latch assembly includes a groove 61 provided on the surface of the driving shaft 6, a spring 62 is fixedly connected to the inner wall of the groove 61, a latch tooth 63 is fixedly connected to the other end of the spring 62, and the latch tooth 63 is latched into the latch hole 32 at the end away from the spring 62.

[0024] When docking the drive shaft 6 and the transverse shaft 3, the transverse shaft 3 is passed through the through hole and then continued to be moved so that the drive shaft 6 is inserted into the slot 31 at the end of the transverse shaft 3, and then the transverse shaft 3 is rotated to adjust the position of the transverse shaft 3 relative to the drive shaft 6, so that the latch tooth 63 can be latched into the latch hole 32 under the elastic force of the spring 62, thereby achieving the docking of the drive shaft 6 and the transverse shaft 3.

[0025] If the driving shaft 6 and the transverse shaft 3 need to be separated, the latching teeth 63 are pressed to retract into the groove 61. After the latching teeth 63 are disengaged from the latching holes 32, the transverse shaft 3 can be separated from the driving shaft 6. At this time, the transverse shaft 3 and the first spiral leaf 4 can be pulled out from the open end of the conveying tube 2.

[0026] like Figure 3 As shown, the end of the latch 63 away from the spring 62 is designed as an inclined surface. The latch 63 is designed as an inclined surface, and when the drive shaft 6 and the cross shaft 3 are connected, the latch 63 is more easily squeezed back into the groove 61.

[0027] like Figure 2 As shown, a rubber ring is fixedly connected to the perforated inner wall of the side wall of the delivery pipe 2, and the rubber ring is in contact with the surface of the horizontal axis 3.

[0028] The rubber ring can increase the sealing performance between the transverse axis 3 and the through hole.

[0029] like Figure 2 and Figure 4 As shown, the unloading assembly 9 includes a plurality of support rods 91 fixed to the inner bottom wall of the hopper 8, the top ends of the plurality of support rods 91 are rotatably connected to a vertical shaft 92, the bottom end surface of the vertical shaft 92 is fixedly connected to a second spiral blade 93, and the second spiral blade 93 is in contact with the inner wall of the feed pipe 7.

[0030] When the material in the hopper 8 enters the conveying pipe 2 along the feeding pipe 7, the material can be uniformly conveyed by the rotation of the second spiral blade 93. Since the second spiral blade 93 is relatively short, normal use will not be affected after being worn.

[0031] like Figure 4 As shown, a second motor 94 is fixedly connected to the top of the outer wall of the hopper 8, and a pulley 95 is fixedly connected to the output shaft of the second motor 94 and the top of the vertical shaft 92, and a synchronous belt 96 is commonly sleeved on the surfaces of the two pulleys 95.

[0032] Under the drive of the synchronous belt 96 , the second motor 94 can drive the vertical shaft 92 and the second spiral blade 93 to rotate.

[0033] Working principle: first add materials into the hopper 8, then start the second motor 94 and the first motor 5, the second motor 94 drives the second spiral blade 93 to rotate, and the materials in the hopper 8 are evenly and slowly fed into the conveying pipe 2 along the feed pipe 7, and then the first motor 5 drives the first spiral blade 4 to rotate, and the materials are discharged from the open end of the conveying pipe 2. In this process, it is only necessary to adjust the speed of the second motor 94 and the first motor 5 to match, to ensure that the feeding speed of the feed pipe 7 just matches the conveying speed of the first spiral blade 4, and to avoid material blockage. If the first spiral blade 4 is severely worn, the first spiral blade 4 and the horizontal axis 3 can be disassembled and pulled out from the conveying pipe 2, which is conducive to the repair of the first spiral blade 4.
