Description

Technical Field

[0001] This utility model relates to the field of rubber powder conveying technology, specifically to a propeller conveyor for rubber powder. Background Technology

[0002] A screw conveyor is a machine that uses a motor to drive a 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. Screw conveyors are divided into two types in terms of conveying form: shafted screw conveyors and shaftless screw conveyors. Shafted screw conveyors are suitable for non-sticky dry powder materials and small granular materials.

[0003] The screw conveyor includes a housing, a drive shaft, helical blades, and a driver. The drive shaft passes through the housing and is pivotally connected to the housing. The helical blades are fixed to the drive shaft by welding. The driver is fixedly connected to the drive shaft. When the driver is working, the torque output by the driver is transmitted to the drive shaft, and the drive shaft transmits the torque to the helical blades.

[0004] Although rubber powder is dried by a dryer before entering the screw conveyor, it cannot be guaranteed that the dried rubber powder is completely free of moisture. Therefore, under normal circumstances, rubber powder still contains a small amount of moisture. During the process of pushing the rubber powder by the screw blades, the rubber powder is prone to sticking to the screw blades, causing the rubber powder to clog the screw conveyor.

[0005] Based on the above, currently, paddles are used instead of spiral blades. The paddles are fixed to the screw, and the screw passes through the drive shaft and is fixed to the nut, thereby locking the spiral blades onto the drive shaft. However, during operation, the paddles are easily subjected to force, which can cause the nut to loosen, resulting in the screw and paddles becoming loose. After the paddles loosen, they will bend under force, which can cause the powder to clog the screw conveyor. Utility Model Content

[0006] This invention provides a propeller conveyor for rubber powder, which can prevent the propeller blades from loosening and deforming.

[0007] The technical solutions to the above technical problems are as follows:

[0008] A propeller conveyor for rubber powder includes a housing, a drive shaft, blades, a screw, a nut, and a driver. The drive shaft passes through the housing and is pivotally connected to the housing. Multiple blades are distributed around the drive shaft. The driver is fixedly connected to the drive shaft. The conveyor also includes a first saddle and a second saddle. The first saddle is fixed to the blades and the screw respectively. The end face of the first saddle has a first engagement portion, and the end of the second saddle has a second engagement portion. After the screw passes through the drive shaft and the second saddle and is connected to the nut, the drive shaft is clamped between the first saddle and the second saddle. The first engagement portion matches the circumferential surface of the drive shaft, and the second engagement portion matches the circumferential surface of the drive shaft.

[0009] Furthermore, the blade is provided with a first mounting groove, the screw passes through the first saddle and engages with the first mounting groove, and the screw is welded and fixed to the blade.

[0010] Furthermore, the blades are fan-shaped.

[0011] Furthermore, the first saddle is provided with a second slot, into which the blade is inserted and welded to the first saddle.

[0012] In this invention, by adding a first saddle and a second saddle, and matching the first joint with the circumferential surface of the drive shaft and the second joint with the circumferential surface of the drive shaft, the drive shaft is clamped between the first saddle and the second saddle. Through the cooperation of the first joint and the second joint with the drive shaft, not only can the installation angle of the blade be limited, but the first saddle and the second saddle also increase the contact area with the drive shaft. Under the stable clamping effect of the first saddle and the second saddle on the drive shaft, the screw is prevented from loosening, and the position of the blade is ultimately stabilized.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 7 As shown, the propeller conveyor for rubber powder of this utility model includes a housing 1, a drive shaft 2, a blade 3, a screw 4, a nut 5, a driver, a first saddle 6, and a second saddle 7. The drive shaft 2 passes through the housing 1 and is pivotally connected to the housing 1. A bearing is installed on the housing 1, and the drive shaft 2 passes through the inner ring of the bearing and is fixed to the inner ring. The drive shaft 2 can be a hollow shaft or a solid shaft. In this utility model, the drive shaft 2 is preferably a hollow shaft. The drive shaft 2 is provided with multiple sets of radially opened through holes. Each set of through holes includes multiple mounting holes arranged at intervals along the axial direction of the drive shaft 2. The first set of through holes is located at 0° on the circumference, the second set of through holes is located at 90° on the circumference, the third set of through holes is located at 180° on the circumference, and the fourth set of through holes is located at 270° on the circumference. The four sets of through holes are staggered in the circumferential direction of the drive shaft 2.

[0024] The driver is fixedly connected to the drive shaft 2. The driver is located outside the housing 1. The driver consists of a motor and a reducer. The motor is preferably an electric motor, and the reducer is preferably a gear reducer. The torque output end of the motor is fixed to the input end of the gear reducer, and the output end of the gear reducer is fixed to the drive shaft 2.

[0025] There are multiple blades 3 distributed around the drive shaft 2. These blades 3 are fan-shaped. The fan-shaped blades 3 can convert the torque of the engine drive into propulsion force, thereby improving the pushing efficiency.

[0026] There are multiple first saddles 6 and second saddles 7. The first saddles 6 are fixed to the blade 3 and the screw 4 respectively. That is, each first saddle 6 is fixed to one blade 3 and one screw 4 respectively. The end face of the first saddle 6 is provided with a first connecting part 6a, and the end of the second saddle 7 is provided with a second connecting part 7a. After the screw 4 passes through the through hole on the drive shaft 2 and the second saddle 7 is connected to the nut 5, the drive shaft 2 is clamped between the first saddle 6 and the second saddle 7. The first connecting part 6a matches the circumferential surface of the drive shaft 2, and the second connecting part 7a matches the circumferential surface of the drive shaft 2.

[0027] In this invention, the nut 5 is preferably a lock nut to prevent loosening. The first joint 6a is a groove, and the wall of the groove is a curved surface that matches the circumferential surface of the drive shaft 2. The second joint 7a is a groove, and the wall of the groove is a curved surface that matches the circumferential surface of the drive shaft 2.

[0028] By engaging with the drive shaft 2 through the first joint 6a and the second joint 7a, the installation angle of the blade 3 can be limited. Furthermore, the first saddle 6 and the second saddle 7 increase the contact area with the drive shaft 2. Under the stable clamping effect of the first saddle 6 and the second saddle 7 on the drive shaft 2, the screw 4 is prevented from loosening, and the position of the blade 3 is ultimately stabilized.

[0029] In this invention, the blade 3 is provided with a first mounting groove 3a, and the screw 4 passes through the first saddle 6 and engages with the first mounting groove 3a. The screw 4 is welded and fixed to the blade 3. Since the blade 3 will be subject to the resistance of rubber powder during operation, extending the screw 4 into the first mounting groove 3a of the blade 3 and welding it to the blade 3 not only increases the strength, but also, when the drive shaft 2 rotates, it transmits power to the screw 4. When the screw 4 drives the blade 3 to rotate and is hindered by the rubber powder, the blade 3 is less likely to be damaged.

[0030] The first saddle 6 is provided with a second slot 6b, into which the blade 3 is inserted and welded to the first saddle 6. This structure increases the contact area between the blade 3 and the first saddle 6, and the circumferential force on the blade 3 can be transferred to the first saddle 6, thereby helping to improve the service life of the blade 3.

[0031] Finally, it should be noted that the above-described embodiments are merely preferred embodiments of the present invention used to illustrate the technical solutions of the present invention, and are not intended to limit them, much less limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to depart from the scope of protection of the claims.
