[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figures 1-3 This utility model provides a device for discharging diverting sand, including a base frame 1, a material box 4 on the top of the base frame 1, the bottom of the material box 4 being an inclined surface, the material box 4 being able to store diverting sand, a conveying cylinder 7 fixedly installed inside the material box 4, a drive assembly 11 on the top of the conveying cylinder 7, the drive assembly 11 including a first motor frame 111 fixedly installed on the conveying cylinder 7, a first drive motor 112 being installed at the top inside the first motor frame 111, the bottom end of the output shaft of the first drive motor 112 being connected to the top end of the rotating shaft 16 via a coupling, and a first support sleeve 113 being sleeved on the surface of the first drive motor 112, the first support sleeve 113 being able to... The first drive motor 112 provides limiting support, the first support sleeve 113 is fixedly installed inside the top of the conveying cylinder 7, the bottom of the output shaft of the drive assembly 11 is provided with a rotating shaft 16, and a feeding auger 17 is fixedly installed on the surface of the rotating shaft 16. The feeding auger 17 can transport the bottom guiding sand to the top. A handrail 5 is fixedly installed on one side of the base frame 1, and a handle 6 is fixedly installed on the handrail 5. The handrail 5 and the handle 6 work together to facilitate the adjustment of the structural position. A limiting frame 3 is fixedly installed on the top of the base frame 1, and the material box 4 is snapped into the inside of the limiting frame 3. Four casters 2 are provided at the bottom of the base frame 1, and the four casters 2 are placed symmetrically in a circle.

[0018] In the above solution, it should be noted that: the universal wheel 2 is a roller with a built-in brake pad in the prior art. When the dispensing device moves to the working area, the universal wheel 2 can be locked by pressing the brake pad on the universal wheel 2. When the brake pad is pulled up, the universal wheel 2 can be unlocked. At the same time, there is a gap between the bottom of the conveying cylinder 7 and the bottom of the inner cavity of the material box 4, so that the guiding sand will flow along the inclined surface of the bottom of the inner cavity of the material box 4 to the vicinity of the bottom of the conveying cylinder 7, which makes it convenient to use the conveying cylinder 7 to transport the guiding sand from a low place to a high place.

[0019] In this embodiment, before the diversion sand needs to be added, the diversion sand can be poured into the material box 4. Then, the first drive motor 112 can be controlled to work, driving the rotating shaft 16 and the feeding auger 17 to rotate. The feeding auger 17 rotates and, with the help of the limiting space inside the conveying cylinder 7, can transport the diversion sand in the material box 4 from the bottom of the conveying cylinder 7 to the top, preparing for the subsequent addition of diversion sand.

[0020] Please see Figure 2 A primary feed cylinder 8 and a mounting plate 14 are provided on one side of the feed cylinder 7. The mounting plate 14 provides installation space for the electric push rod 15. The electric push rod 15 is provided on the top of the mounting plate 14. A secondary feed cylinder 9 is slidably connected to the surface of the primary feed cylinder 8 and fixedly installed on the top of the electric push rod 15.

[0021] In this embodiment, when it is necessary to quickly adjust the throwing height, the electric push rod 15 can be directly controlled to drive the three-stage feeding cylinder 10 and the two-stage feeding cylinder 9 to rise and fall. At this time, the two-stage feeding cylinder 9 slides on the surface of the first-stage feeding cylinder 8 to achieve stable lifting and lowering control.

[0022] Please see Figure 1 , Figure 2 and Figure 4 A tertiary feeding cylinder 10 is fixedly installed at the bottom of the secondary feeding cylinder 9. A quaternary feeding cylinder 13 is slidably connected inside the tertiary feeding cylinder 10. An adjustment component 12 is provided between the drive component 11 and the quaternary feeding cylinder 13. The adjustment component 12 includes a mounting bracket 121 fixedly installed on the tertiary feeding cylinder 10. A second motor bracket 122 is fixedly installed on the top of the mounting bracket 121. A second drive motor 123 is provided inside the second motor bracket 122. A first transmission arm 125 is provided at the bottom of the output shaft of the second drive motor 123. A second transmission arm 126 is hinged to the bottom of the first transmission arm 125. The second transmission arm 126 is hinged to the quaternary feeding cylinder 13. A second support sleeve 124 is provided inside the mounting bracket 121. The output shaft of the second drive motor 123 is sleeved inside the second support sleeve 124. The second support sleeve 124 can sleeve and support the output shaft of the second drive motor 123 to ensure the stability of the second drive motor 123 when it rotates.

[0023] In this embodiment, when it is necessary to further adjust the dispensing device according to the dispensing position, the second drive motor 123 can be controlled to work, driving the first transmission arm 125 to rotate. The rotation of the first transmission arm 125 can push the second transmission arm 126 to swing. The angular swing of the second transmission arm 126 can push the fourth-stage feeding cylinder 13 to move. At this time, the fourth-stage feeding cylinder 13 can slide inside the third-stage feeding cylinder 10, realizing stable adjustment of the fourth-stage feeding cylinder 13. In the above scheme, it should be noted that: since the first transmission arm 125 and the second transmission arm 126 are hinged to each other, and the second transmission arm 126 is also hinged to the fourth-stage feeding cylinder 13, when the first transmission arm 125 rotates, it can push the second transmission arm 126 to swing and rotate. At this time, the fourth-stage feeding cylinder 13 is driven by linear displacement and angular rotation, and the fourth-stage feeding cylinder 13 has a tendency to rotate and move linearly. However, since the rotation direction of the fourth-stage feeding cylinder 13 has been restricted, the fourth-stage feeding cylinder 13 can only undergo linear displacement.

[0024] The working principle and usage process of this utility model are as follows: First, pour the diversion sand into the material box 4, then hold the handle 6 and push the device to the approximate placement position with the help of the universal wheel 2. Then, control the electric push rod 15 to drive the three-stage discharge cylinder 10 and the two-stage discharge cylinder 9 to rise and fall. Next, by controlling the second drive motor 123 to work, the first transmission arm 125 is driven to rotate. The rotation of the first transmission arm 125 can push the second transmission arm 126 to swing. The angular swing of the second transmission arm 126 can push the fourth-stage feeding cylinder 13 to move. The height and position of the fourth-stage feeding cylinder 13 are adjusted and controlled. The port of the fourth-stage feeding cylinder 13 needs to be placed above the feeding port. Finally, by controlling the first drive motor 112 to work, the rotating shaft 16 and the feeding auger 17 are driven to rotate. The feeding auger 17 rotates and, with the help of the limiting space inside the feeding cylinder 7, can transport the guiding sand in the material box 4 from the bottom of the feeding cylinder 7 to the top, until the guiding sand is controlled to the position of the first-stage feeding cylinder 8, and then falls from the first-stage feeding cylinder 8 into the second-stage feeding cylinder 9, and then successively falls into the feeding port through the third-stage feeding cylinder 10 and the fourth-stage feeding cylinder 13.
