[0028] Embodiment 1

[0029] See also Figures 1 to 11 The utility model provides a technical solution: a feeding device for the production of automotive urea solution, comprising a cart 1 and a conveying auger 4, a support plate 2 is installed on the top of the cart 1, a discharging frame 5 is installed on the right side of the conveying auger 4, a slide groove a9 is opened on the right side of the support plate 2, a moving block 14 is slidably connected to the inner wall of the slide groove a9, two installation frames 8 are installed on the top of the moving block 14, two fixed frames 12 are installed on the left side of the support plate 2, a connecting block 11 is hinged on the top of the fixed frame 12, a fixed plate 3 is installed on the top of the two connecting blocks 11, another two installation frames 8 are installed on the right side of the bottom of the fixed plate 3, and connecting rods 7 are installed between the upper and lower installation frames 8.

[0030] First, let the moving block 14 slide to the left along the inner wall of the slide groove a9, thereby driving the two mounting frames 8 on the lower side to move to the left. Since a connecting rod 7 is hinged between the upper and lower mounting frames 8, and a connecting block 11 is installed on the left side of the bottom of the cart 1, and the connecting block 11 is hinged to the fixed frame 12, the two mounting frames 8 on the lower side move to the left to drive the fixed plate 3 to flip to the left. Since the fixed frame 12 is fixed to the left side of the top of the support plate 2, the fixed plate 3 is hinged to the fixed frame 12, and then the angle of the fixed plate 3 is adjusted to the left, and the conveying auger 4 is fixed to the top of the fixed plate 3, so as to adjust the angle of the conveying auger 4. After the adjustment is completed, the urea raw material is fed into the interior of the mixing tank through the discharging frame 5, thereby improving the flexibility of the feeding device.

[0031] Embodiment 2

[0032] On the basis of Example 1, in order to drive the moving block 14 to move and drive the fixed plate 3 to adjust, a motor 6 is installed on the right side of the support plate 2, and the output end of the motor 6 is fixedly connected to a threaded rod 13, and slide rods 10 are installed on the front and rear sides of the slide groove a9. Through the setting of the slide rod 10, the moving block 14 can be more stable during the movement, thereby preventing it from being offset; the threaded rod 13 runs through the right side of the support plate 2, and the left end of the threaded rod 13 is rotatably connected to the middle part of the support plate 2, the middle part of the moving block 14 is threadedly connected to the outside of the threaded rod 13, and the front and rear sides of the moving block 14 slide on the outside of the slide rod 10.

[0033] First, start the motor 6 to drive the threaded rod 13 at its output end to rotate. Since the middle part of the moving block 14 is threadedly connected to the outer side of the threaded rod 13, the moving block 14 is driven to move to the left. At the same time, the moving block 14 slides on the outer side of the two slide bars 10, and then the moving block 14 slides to the left along the outer side of the slide bar 10, and the fixed plate 3 is simultaneously driven to be adjusted to facilitate the adjustment of the feeding angle of the conveying auger 4.

[0034] Embodiment 3

[0035] On the basis of Example 2, in order to prevent the urea raw material inside the moving conveying auger 4 from falling, a baffle 15 is inserted at the bottom of the discharging frame 5, and a slide groove b18 is opened on the left and right sides of the baffle 15. The inner wall of the slide groove b18 is slidably connected to a limit plate 17, and the limit plate 17 plays a limiting role, thereby preventing the rubber column 16 from being pushed out of the slide groove b18 by the elastic force of the spring 19. The rubber column 16 is installed on one side of the limit plate 17, and the spring 19 is installed on the other side of the limit plate 17.

[0036] Before feeding, first pull the baffle 15 forward to separate it from the discharging frame 5. After feeding, insert the baffle 15 to the bottom of the discharging frame 5. At this time, since the left and right sides of the baffle 15 are provided with slide grooves b18, and the inner wall of the slide groove b18 slides with a limit plate 17, and a rubber column 16 is installed on one side of the limit plate 17, and a spring 19 is installed on the other side, at this time, since the baffle 15 will slide backward along the inner wall of the discharging frame 5, the two sides will be driven to move. The rubber column 16 moves toward the middle of the baffle 15, and the ends of the two rubber columns 16 that are separated are always in contact with the inner wall of the discharge frame 5. When the baffle 15 is fully inserted to the bottom of the discharge frame 5, at this time, due to the elastic force of the spring 19, the limit plate 17 is driven to move, and the rubber column 16 is driven to be inserted into the corresponding hole groove on the inner wall of the discharge frame 5, and then the baffle 15 is stuck at the bottom of the discharge frame 5 to prevent the urea raw material inside the conveying auger 4 from falling from the discharge frame 5.

[0037] Embodiment 4

[0038] On the basis of the third embodiment, in order to facilitate the reset of the rubber column 16, the ends of the left and right springs 19 that are close to each other are installed on the inner wall of the slide groove b18, so as to facilitate the reset of the rubber column 16; the rubber column 16 penetrates the baffle 15, and the ends of the left and right rubber columns 16 that are separated are inserted into the inner wall of the discharge frame 5.

[0039] When the baffle 15 is reset, the rubber column 16 will always keep in contact with the inner wall of the discharge frame 5. When the baffle 15 is fully inserted to the bottom of the discharge frame 5, the elastic force of the spring 19 will drive the limit plate 17 to move, thereby driving the rubber column 16 to be inserted into the inner wall of the hole groove reserved on the inner wall of the discharge frame 5, and then the baffle 15 and the discharge frame 5 are clamped together.

[0040] In actual use, first let the moving block 14 slide to the left along the inner wall of the slide groove a9, thereby driving the two mounting frames 8 on the lower side to move to the left. Since the connecting rod 7 is hinged between the upper and lower mounting frames 8, and the connecting block 11 is installed on the left side of the bottom of the cart 1, and the connecting block 11 is hinged to the fixed frame 12, the two mounting frames 8 on the lower side move to the left to drive the fixed plate 3 to flip to the left. Since the fixed frame 12 is fixed to the left side of the top of the support plate 2, the fixed plate 3 is hinged to the fixed frame 12, and then the angle of the fixed plate 3 is adjusted to the left, and the conveying auger 4 is fixed to the top of the fixed plate 3, so as to adjust the angle of the conveying auger 4. After the adjustment is completed, the urea raw material is fed into the interior of the mixing tank through the discharging frame 5, thereby improving the flexibility of the feeding device.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
