[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Example: Refer to Appendix Figure 1-4 As shown, an automatic feeding device for a mortar mixer is provided, including a frame, a feeding device 1 hinged to the frame for feeding materials into the mortar mixer, and an adjusting component 2 for driving the feeding device to swing up and down along the hinge point. A supporting component 3 for supporting the feeding device is provided above the adjusting component.

[0026] In this embodiment of the utility model, the frame includes a connecting plate 202 and a support frame 201 and a fixing frame 203 respectively disposed on both sides of the connecting plate.

[0027] In this embodiment of the utility model, the adjustment component includes a movable block disposed on the frame and movable along the connecting plate of the frame. A lead screw 205 is inserted through the middle of the movable block 206, and the movable block is screwed to the lead screw. A servo motor 204 for driving the lead screw to rotate is installed on the frame.

[0030] This invention, by setting an adjustment component 2, activates a servo motor 204 to adjust the height of the feed inlet of the mortar mixer according to the required feeding position. This causes the output shaft of the servo motor 204 to drive the lead screw 205 to rotate, making the movable block 206 threadedly connected to the lead screw 205. The movable block 206 then slides on the connecting plate 202, allowing one end of the rotating plate 207 to be rotatably connected to the feeding pipe 101 via a rotating shaft B, and the other end to be rotatably connected to the movable block 206 via a rotating shaft C. This causes the feeding pipe 101 to rotate on the support frame 201 via a rotating shaft A until the feeding pipe 101 rotates to the appropriate position, placing the discharge port 103 above the feed inlet of the mortar mixer. Compared to existing technologies, this invention has a simple and reasonable structure, ingenious design, and can adjust the feeding angle of the automatic feeding device body 1 according to different heights of mortar mixers, making it highly applicable.

[0031] In this embodiment of the utility model, the support component 3 includes a square sleeve 302 disposed next to the movable block of the adjustment component and a cylinder seat fixed above the movable block of the adjustment component. A cylinder 301 is mounted on the cylinder seat. A support plate 303 is disposed above the square sleeve. The support plate can slide along the length direction of the square sleeve. The support plate is fixedly connected to the output shaft of the cylinder. A rotating block 304 is disposed above the support plate. A support block 305 is fixed above the rotating block. The upper surface of the support block is an inclined surface.

[0032] Of course, the cylinder can be a servo cylinder; a sliding component can be provided between the support plate and the square cylinder or no sliding component can be provided; the sliding component can include a slider provided below the movable block and a groove provided on the upper surface of the connecting plate.

[0033] Specifically, the support assembly 3 is arranged on the movable block 206; the square cylinder 302 is sleeved on the lead screw 205 and fixedly connected to the movable block 206, that is, the lead screw extends inside the square cylinder; the support plate 303 is slidably arranged on the square cylinder 302 and fixedly connected to the piston end of the servo cylinder 301; the rotating block 304 is rotatably connected to the support plate 303 through the rotating shaft D; the support block 305 is fixed on the rotating block 304; the support plate 303 has a U-shaped structure with a smaller top and a larger bottom; the support block 305 has a right-angled trapezoidal structure, and the inclined surface of the support block 305 is in contact with the outer surface of the feeding pipe 101; when the movable block 206 moves to the side where the lead screw 205 is away from the servo motor 204, the square cylinder 302 does not contact the automatic feeding device body 1.

[0034] This invention, by setting up a support assembly 3, activates the servo cylinder 301 simultaneously with the servo motor 204, causing the piston rod of the servo cylinder 301 to extend or retract, allowing the support plate 303 to slide on the square cylinder 302. By controlling the extension or retraction of the piston rod of the servo cylinder 301, the rotating block 304 rotates on the support plate 303 via the rotating shaft D, allowing the support block 305 to automatically adapt to the rotation position. This ensures that the inclined surface of the support block 305 is always in contact with the outer surface of the feeding tube 101, enabling the support plate 303 and the support block 305 to support the feeding tube 101. This enhances the connection strength between the rotating plate 207 and the feeding tube 101, improving the stability of the feeding tube 101's position.

[0035] In this embodiment of the present invention, the feeding device 1 includes a feeding pipe 101 and a spiral auger 105 disposed inside the feeding pipe. An inlet 102 is provided above one side of the feeding pipe, and a discharge port 103 is provided below the other side of the feeding pipe. The inlet, discharge port and feeding pipe are connected. A motor base is provided at one end of the feeding pipe near the inlet. A feeding motor 104 for driving the spiral auger to rotate is provided on the motor base. The spiral auger is rotatably disposed inside the feeding pipe. One end of the spiral auger passes through the feeding pipe and is connected to the output shaft of the feeding motor.

[0036] The aforementioned inlet 102 is fixed to the feeding pipe 101 and connected to the feeding pipe 101; the outlet 103 is fixed to the feeding pipe 101 and connected to the feeding pipe 101, and the outlet 103 is arranged above the inlet of the mortar mixer.

[0037] In this embodiment of the invention, the servo motor is fixed to the frame by bolts.

[0038] In this embodiment of the utility model, the working principle is as follows: During use, firstly, according to the required height of the mortar mixer's feed inlet, the servo motor 204 is started, causing the output shaft of the servo motor 204 to drive the lead screw 205 to rotate. This causes the movable block 206 to be threadedly connected to the lead screw 205, and the movable block 206 to drive the square cylinder 302 to slide on the connecting plate 202. One end of the rotating plate 207 is rotatably connected to the feeding pipe 101 via the rotating shaft B, and the other end is rotatably connected to the movable block 206 via the rotating shaft C. This causes the feeding pipe 101 to rotate on the support frame 201 via the rotating shaft A until the feeding pipe 101 rotates to the appropriate position, and the discharge... The feed inlet 103 can be positioned above the feed inlet of the mortar mixer. Simultaneously with starting the servo motor 204, the servo cylinder 301 is activated, causing the piston rod of the servo cylinder 301 to extend or retract, allowing the support plate 303 to slide on the square cylinder 302. By controlling the extension or retraction of the piston rod of the servo cylinder 301, the rotating block 304 rotates on the support plate 303 via the rotating shaft D, allowing the support block 305 to automatically adapt to the rotation position. This ensures that the inclined surface of the support block 305 is always in contact with the outer surface of the feed pipe 101, enabling the support plate 303 and the support block 305 to support the feed pipe 101 and improve the stability of the feed pipe 101's position.
