A bottom plate is arranged below the housing, and an adjustment assembly for adjusting the angle of the housing is arranged between the housing and the bottom plate. A plurality of universal wheels are fixedly arranged at the bottom of the bottom plate to facilitate the movement of the screw feeder, and two reinforcement assemblies for increasing the position stability of the screw feeder are arranged on the bottom plate

[0004] In the actual use of the above adjustable screw feeder, the applicant found that when adjusting the angle of the screw feeder, since the feed hopper is fixed on the feed pipe, the direction of the feed hopper will change during adjustment. At this time, it is necessary to adapt the feeding equipment, and the operation is very troublesome. Moreover, the inclined discharge hopper is likely to cause material spillage, which is not conducive to feeding. Similarly, when adjusting the discharge pipe, the feeding direction will also change, and it is very difficult for personnel to accurately ensure that the material just falls into the corresponding position by naked eyes. Therefore, after the height is adjusted, personnel still need to slightly move the equipment to adjust the position of the discharge pipe, and the operation is very troublesome. In order to solve the above problems, a screw feeder with an angle adjustment function is provided Summary of the Utility Model

[0019] The following will be combined with Figures 1 - 3 A screw feeder with an adjustable angle in the embodiments of the present utility model will be described in detail.

[0020] Embodiment:

[0021] A screw feeder with an adjustable angle provided in an embodiment of the present utility model, referring to Figures 1 to 3 as shown, includes a bottom plate 1 and a main body 2 of the screw feeder. A support 3 is fixedly installed on the bottom plate 1, a ball head feeding pipe 4 is fixedly connected to the support 3, a feeding hopper 19 is flange-connected to the upper end of the ball head feeding pipe 4, a ball bowl feeding pipe 5 is installed on one side of the main body 2 of the screw feeder, the ball head feeding pipe 4 and the ball bowl feeding pipe 5 are ball-connected together, shaft rods 6 are fixedly installed on opposite sides of the ball bowl feeding pipe 5, the shaft rods 6 are rotatably installed on the support 3, a first hydraulic rod 7 is rotatably installed on the top surface of the bottom plate 1, and the piston rod of the first hydraulic rod 7 is rotatably connected to the main body 2 of the screw feeder. With this structure, materials can be put into the feeding hopper 19, the feeding hopper 19 guides the materials into the ball head feeding pipe 34, then into the ball bowl feeding pipe 5, and finally the materials are guided into the interior of the main body 2 of the screw feeder, and then the materials can be conveyed. Moreover, the operator can start the first hydraulic rod 7 to adjust the conveying angle of the main body 2 of the screw feeder;

[0022] When the above device is in use, the ball head of the ball head feeding pipe 4 and the ball bowl feeding pipe 5 are connected and matched. Therefore, when adjusting the conveying angle of the screw feeder main body 2, the ball bowl feeding pipe 5 can rotate adaptively on the ball head feeding pipe 4 at this time, so as to keep the height and position of the feeding hopper 19 unchanged. In this way, when adjusting the conveying angle, it is not necessary to adjust the feeding equipment to adapt to the feeding hopper 19 on the ball head feeding pipe 4, which is more convenient for actual use. Moreover, the feeding hopper is always opened upward, and the materials are not easy to scatter during feeding.

[0023] Reference Figures 1 to 3 As shown in the figure, a discharge pipe 8 is installed on the other side of the screw feeder main body 2. A shaft frame 9 is fixedly installed on the discharge pipe 8. A discharge adjusting plate 10 is rotatably installed on the shaft frame 9. A second hydraulic rod 11 is rotatably connected to the discharge pipe 8. The piston rod of the second hydraulic rod 11 is rotatably connected to the discharge adjusting plate 10. This structure uses the discharge pipe 8 to facilitate the discharge of materials inside the screw feeder main body 2. And when adjusting the angle of the screw feeder main body 2, the discharge angle of the discharge pipe 8 will change at this time. At this time, the operator can start the second hydraulic rod 11 to drive the discharge adjusting plate 10 to rotate and adjust the angle on the shaft frame 9, and use the discharge adjusting plate 10 to change the discharge direction of the materials. In this way, it is not necessary for the operator to move the entire screw feeder main body 2 to adjust and use, and the practicality of the equipment is better.

[0024] Reference Figures 1 to 3 As shown in the figure, both the ball bowl feeding pipe 5 and the discharge pipe 8 are fixedly installed on the conveying pipe body 15. The piston rod of the first hydraulic rod 7 is rotatably connected to the conveying pipe body 15.

[0025] Reference Figures 1 to 3 As shown in the figure, universal wheels 12 are fixedly installed at the four end corners of the bottom of the bottom plate 1. This structure uses the universal wheels 12 to facilitate the operator to move the entire screw feeding mechanism on the bottom plate 1.

[0026] Reference Figures 1 to 3 As shown in the figure, support screws 13 are fixedly connected by threads at the four ends of the bottom plate 1. A support foot 14 is fixedly installed at the bottom end of the support screw 13. In this structure, when the screw feeding mechanism moves in place, the operator can then rotate the support screw 13 at this time, so that the support foot 14 abuts against the ground, thereby stabilizing the equipment.

[0027] Reference Figures 1 to 3 As shown in the figure, the screw feeder main body 2 includes a conveying pipe body 15. A rotating rod 16 is rotatably connected inside the conveying pipe body 15. A spiral blade 17 is welded on the outer wall of the rotating rod 16. One end of the conveying pipe body 15 is fixedly installed with a motor 18. The motor 18 is connected to the rotating rod 16 through an output shaft. In this structure, starting the motor 18 drives the threaded blade 17 on the rotating rod 16 to rotate, and then cooperating with the conveying pipe body 15, continuous conveying of materials can be realized.

[0028] The implementation principle of a spiral feeder with an adjustable angle according to an embodiment of the present application is as follows: During use, the operator first roughly moves the main body 2 of the spiral feeder to the corresponding position through the universal wheels 12 of the bottom plate 1. Then, the operator can rotate the support screw 13 so that the support feet 14 abut against the ground to stabilize the equipment. Then, the operator starts the first hydraulic rod 7 to adjust the angle of the main body 2 of the spiral feeder according to the conveying height. At this time, the spherical bowl feeding pipe 5 on the main body 2 of the spiral feeder rotates on the bracket 3 through the shaft rod 6, so as to adjust the height of the discharging pipe 8. Then, the operator can put the material into the feeding hopper 19. The feeding hopper 19 guides the material into the spherical head feeding pipe 34, then into the spherical bowl feeding pipe 5, and finally guides the material into the interior of the main body 2 of the spiral feeder. Then, the motor 18 is started to drive the threaded blade 17 on the rotating rod 16 to rotate, and then cooperate with the conveying pipe body 15, so as to realize continuous material conveying;

[0029] During use, the spherical head of the spherical head feeding pipe 4 and the spherical bowl of the spherical bowl feeding pipe 5 are connected and matched. Therefore, when adjusting the conveying angle of the main body 2 of the spiral feeder, at this time, the spherical bowl feeding pipe 5 can rotate adaptively in the spherical head feeding pipe 4, so as to keep the height and position of the feeding hopper 19 unchanged. In this way, when adjusting the conveying angle, it is not necessary to adjust the feeding equipment to adapt to the feeding hopper 19 on the spherical head feeding pipe 4, which is more convenient for actual use;

[0030] Moreover, the second hydraulic rod 11 can be started to drive the discharging adjusting plate 10 to rotate on the shaft frame 9 to adjust the angle, and the discharging direction of the material is changed by using the discharging adjusting plate 10. In this way, it is not necessary for the operator to move the entire equipment main body to adjust the discharging pipe 8, and the practicality of the equipment is better.
