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 commonly used screw conveyors with straight end discharge need to clean and discharge residual material in time, and the long discharge path of the machine body leads to the problem of increased energy consumption. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a screw conveyor that facilitates material unloading is provided to solve the problem that residual material in commonly used screw conveyors with straight end unloading needs to be cleaned and discharged in a timely manner, and that the long unloading path of the screw conveyor leads to increased energy consumption.

[0004] To achieve the above objectives, a screw conveyor for easy unloading is provided, comprising: an upper casing and a lower arc-shaped casing, wherein the lower arc-shaped casing is fitted and engaged at the lower end of the upper casing.

[0005] A left support frame is welded to the left side of the upper housing of the conveyor, and a right support frame is welded to the right side of the upper housing of the conveyor. A transmission plate is welded to the rear end face of the lower arc-shaped housing. The transmission plate is connected to a fixing block through a fixing rod. Fixing blocks are welded to the rear ends of both the left and right support frames. A worm gear is installed on the left side of the fixing rod, and a worm is meshed with the front side of the worm gear.

[0006] Furthermore, a feed pipe is fixed to the right side of the upper end face of the upper housing of the conveyor, a discharge pipe is fixed to the left side of the lower end face of the lower arc-shaped housing, and a rotating column is installed on the inner side wall of the upper housing of the conveyor.

[0007] Furthermore, a helical blade is fixed on the surface of the rotating column, and a motor is connected to the right side of the rotating column via a coupling; and the motor is fixed at the right end face of the upper housing of the conveyor.

[0008] Furthermore, the front end face of the upper housing of the conveyor is fastened to the lower arc-shaped housing by fasteners, and the outer surfaces of the upper housing and the lower arc-shaped housing of the conveyor are bound with fixing straps.

[0009] Furthermore, a fixing rod is connected through the inner side of the transmission plate, and the two ends of the fixing rod are connected to the fixing block through bearings.

[0010] Furthermore, the right end of the worm is axially connected to the groove of the left support frame, and a worm head is welded to the left end of the worm; the worm head is located on the left side of the left support frame.

[0011] Furthermore, the lower arc-shaped shell is a hollow semi-cylindrical shape that fits onto the lower end face of the upper shell of the conveyor.

[0012] The beneficial effects of this utility model are as follows: the screw conveyor of this utility model, which facilitates material unloading, utilizes the meshing rotation of a worm gear to drive the transmission plate on the surface of the fixed rod to rotate, causing the lower arc-shaped housing connected to the transmission plate to flip downwards, so that the lower end face of the screw conveyor is in an open state. By controlling the screw blades to rotate briefly, it is convenient to quickly and efficiently discharge the remaining material fully from the inside of the screw conveyor, thus realizing an energy-saving and convenient unloading function. This avoids the long-term retention of remaining material inside the machine, which affects the normal operation of the screw conveyor. At the same time, the separability of the lower end housing of the screw conveyor facilitates the daily cleaning and internal maintenance of the screw conveyor. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1 to 4 As shown, this utility model provides a screw conveyor for easy unloading, comprising: an upper housing 1 and a lower arc-shaped housing 4, wherein the lower arc-shaped housing 4 is fitted and engaged at the lower end of the upper housing 1.

[0020] A left support frame 2 is welded to the left side of the upper housing 1 of the conveyor, and a right support frame 21 is welded to the right side of the upper housing 1 of the conveyor. A transmission plate 42 is welded to the rear end face of the lower arc-shaped housing 4. A fixing block 22 is connected to the transmission plate 42 through a fixing rod 43. Fixing blocks 22 are welded to the rear ends of both the left support frame 2 and the right support frame 21. A worm gear 44 is installed on the left side of the fixing rod 43. A worm 46 is meshed with the front side of the worm gear 44.

[0021] When there is residual material inside the screw conveyor after the material conveying is completed, open the fastener 13 and loosen the fixing strap 12, place the material holding plate at the lower end of the upper housing 1 of the conveyor, manually rotate the worm head 45, and drive the fixed rod 43 and the transmission plate 42 to rotate through the meshing rotation of the worm 46 and the worm wheel 44. This causes the transmission plate 42 to flip the lower arc-shaped housing 4 downwards and move it away from the lower end face of the upper housing 1 of the conveyor. During the flipping and moving of the lower arc-shaped housing 4, some residual material falls onto the material holding plate. Then, control the screw blade 3 to rotate a few times briefly to facilitate the quick and efficient discharge of the residual material from the inside of the screw conveyor, thus completing the quick unloading and cleaning process of the residual material inside the screw conveyor.

[0022] In this embodiment, a feed pipe 11 is fixed to the right side of the upper end face of the upper housing 1 of the conveyor, and a feed pipe 41 is fixed to the left side of the lower end face of the lower arc-shaped housing 4. A rotating column 31 is installed on the inner side wall of the upper housing 1 of the conveyor. A spiral blade 3 is fixed to the surface of the rotating column 31, and a motor 32 is connected to the right side of the rotating column 31 through a coupling 33; and the motor 32 is fixedly located at the right end face of the upper housing 1 of the conveyor.

[0023] In a preferred embodiment, the feed pipe 11 and the discharge pipe 41 are the fixed inlet and outlet of the screw conveyor. The motor 32 drives the screw blades 3 to rotate through the rotating column 31, so that the screw blades 3 push the material axially, thereby moving the material from the feed pipe 11 to the discharge pipe 41 for discharge.

[0024] In this embodiment, the front end face of the upper housing 1 of the conveyor is fastened to the lower arc-shaped housing 4 by a fastener 13, and the outer surfaces of the upper housing 1 and the lower arc-shaped housing 4 of the conveyor are bound with fixing straps 12.

[0025] As a preferred embodiment, the fastener 13 and the fixing strap 12 can further reinforce the tightness of the connection between the upper housing 1 and the lower arc-shaped housing 4 of the conveyor, and prevent the solid material conveyed by the screw conveyor from entering the gap between the upper housing 1 and the lower arc-shaped housing 4 of the conveyor.

[0026] In this embodiment, a fixing rod 43 is connected through the inner side of the transmission plate 42, and both ends of the fixing rod 43 are connected to the fixing block 22 through bearings. The right end of the worm gear 46 is axially located in the groove of the left support frame 2, and a worm head 45 is welded to the left end of the worm gear 46; the worm head 45 is located on the left side of the left support frame 2. The lower arc-shaped housing 4 is a hollow semi-cylindrical shape that fits against the lower end face of the upper housing 1 of the conveyor.

[0027] As a preferred embodiment, the meshing rotation of the worm 46 and the worm wheel 44 facilitates the rotation of the fixed rod 43, thereby causing the transmission plate 41 and the lower arc-shaped housing 4 connected to the fixed rod 43 to rotate. This causes the lower arc-shaped housing 4 to flip downwards and move away from the lower end face of the upper housing 1 of the conveyor, making it easier to unload all the remaining material inside the lower end face of the upper housing 1 of the conveyor downwards. Furthermore, the separability of the lower end housing of the screw conveyor facilitates daily cleaning and internal maintenance of the screw conveyor, improving the practicality of the screw conveyor.

[0028] This utility model of an easy-to-unload screw conveyor effectively solves the problem of the need for timely cleaning and discharge of residual material in commonly used screw conveyors with straight end unloading, and the problem of increased energy consumption caused by the long unloading path of the screw conveyor body. It facilitates the quick and efficient discharge of residual material from the inside of the screw conveyor, realizing an energy-saving and convenient unloading function. It avoids the long-term retention of residual material inside the machine, which affects the normal operation of the screw conveyor. At the same time, the separability of the lower shell of the screw conveyor facilitates daily cleaning and internal maintenance of the screw conveyor. It is suitable for screw conveyors with easy unloading.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
