[0025] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , where Figure 1 is a schematic structural view of the first embodiment of the quantitative dispenser provided by the present utility model; Figure 2 is Figure 1 a schematic structural view of the interior of the rectangular groove as shown; Figure 3 is Figure 2 a schematic structural view of the baffle as shown; Figure 4 is Figure 2 a partially enlarged view of A as shown;

[0026] Figure 5 is Figure 3Partial enlarged view of B as shown. The quantitative dispenser includes a workbench 1, and a number of groups of support legs 2 are installed on the top of the workbench 1. It is characterized in that: a material bucket 3 is installed between several groups of the support legs 2, a feed pipe 4 is installed on the top of the material bucket 3, a rectangular groove 9 is opened at the top near the front end of the workbench 1, a first motor 5 is installed on the outer wall of the left end of the workbench 1, the output end of the first motor 5 penetrates into the rectangular groove 9, and a threaded rod 11 is fixedly installed at the output end of the first motor 5. The other end of the threaded rod 11 is rotatably connected to the inner wall of the right end of the rectangular groove 9. The threaded rod 11 is threadedly connected with a rectangular block 21. A rotating shaft 23 is installed on the top of the rectangular block 21. The lower end of the rotating shaft 23 is rotatably connected to a disc 22. A number of groups of connecting rods three 24 are installed on the outer wall of the disc 22. The other ends of the number of groups of connecting rods three 24 are respectively installed with a first measuring cylinder 6, a second measuring cylinder 8, a third measuring cylinder 10 and a fourth measuring cylinder 14. A first rectangular plate 7 is installed on the outer wall of the upper ends of the first measuring cylinder 6, the second measuring cylinder 8, the third measuring cylinder 10 and the fourth measuring cylinder 14. The top of the fourth measuring cylinder 14 is in close contact with the discharge port of the material bucket 3. A baffle 15 is in close contact with the bottoms of the first measuring cylinder 6, the second measuring cylinder 8, the third measuring cylinder 10 and the fourth measuring cylinder 14. The bottom of the baffle 15 is in close contact with the top of the workbench 1. A second rectangular plate 26 is installed on the outer walls of the first measuring cylinder 6, the second measuring cylinder 8, the third measuring cylinder 10 and the fourth measuring cylinder 14. A connecting rod one 12 is fixedly installed on the outer walls of the number of groups of baffles 15. The other end of the connecting rod one 12 is rotatably connected to the second rectangular plate 26. A rectangular opening 13 is opened on the top of the workbench 1. The rectangular opening 13 is parallel to the rectangular groove 9. The volumes of the first measuring cylinder 6, the second measuring cylinder 8, the third measuring cylinder 10 and the fourth measuring cylinder 14 are all different.

[0027] A second circular plate 29 is installed on the top of the rotating shaft 23. Four limiting grooves 31 are evenly opened on the top of the disc 22. A circular ring 33 is in close sliding connection with the outer wall of the rotating shaft 23.

[0028] Four limiting blocks 32 are evenly installed on the outer wall of the circular ring 33. The limiting blocks 32 are inserted and connected with the limiting grooves 31. After the limiting grooves 31 are aligned with the limiting blocks 32, the limiting blocks 32 are inserted into the limiting grooves 31, so that the disc 22 stops rotating.

[0029] A number of groups of guide rods 25 are evenly installed at the top of the ring 33. The guide rods 25 penetrate through the second circular plate 29, and the guide rods 25 are slidably connected to the second circular plate 29. A first circular plate 28 is installed at the top of the number of groups of guide rods 25. A convex block 27 is installed at the top of the first circular plate 28. A number of groups of springs 30 are installed between the ring 33 and the second circular plate 29. The springs 30 are sleeved outside the guide rods 25. By pulling the first circular plate 28 upward through the convex block 27, the first circular plate 28 drives the limit block 32 on the ring 33 to leave the limit groove 31 through a number of groups of guide rods 25, thereby unlocking the disc 22. When the disc 22 needs to be adjusted, the ring 33 is lifted upward. When the limit groove 31 is aligned with the limit block 32, the convex block 27 is released, and the spring 30 will automatically drive the ring 33 to move downward, so that the limit block 32 is inserted into the limit groove 31.

[0030] Seals are installed at the connections between the number of groups of baffles 15 and the first measuring cylinder 6, the second measuring cylinder 8, the third measuring cylinder 10, and the fourth measuring cylinder 14. The seals are provided to prevent the leakage of fine powder.

[0031] The working principle of the quantitative dispenser provided by the present utility model is as follows:

[0032] According to the required dosage, the disc 22 is rotated. The disc 22 drives the corresponding measuring cylinder to move to the discharge port of the material bucket 3 through the third connecting rod 24. Then, the first motor 5 is started. The output end of the first motor 5 drives the threaded rod 11 to rotate. The threaded rod 11 drives the rotating shaft 23 to move along the rectangular groove 9 towards the rectangular opening 13 through the rectangular block 21. The rotating shaft 23 drives the first measuring cylinder 6, the second measuring cylinder 8, the third measuring cylinder 10, and the fourth measuring cylinder 14 to move towards the rectangular opening 13 together through the disc 22 and the third connecting rod 24. For the measuring cylinder separated from the discharge port of the material bucket 3, the rectangular plate 1 on the outer wall of its upper end contacts the discharge port of the material bucket 3 in time to block the material. When the measuring cylinder moves above the rectangular opening 13, the baffle 15 at the bottom of the measuring cylinder automatically rotates and opens along the second rectangular plate 26 due to the lack of support from the workbench 1, thereby completing automatic feeding.

[0033] Compared with the related art, the quantitative dispenser provided by the present utility model has the following beneficial effects:

[0034] Rotate the disc 22. The disc 22 drives the corresponding measuring cylinder to move to the discharging port of the material bucket 3 through the third connecting rod 24. Then, start the first motor 5. The output end of the first motor 5 drives the threaded rod 11 to rotate. The threaded rod 11 drives the rotating shaft 23 to move along the rectangular groove 9 towards the rectangular opening 13 through the rectangular block 21. The rotating shaft 23 drives the first measuring cylinder 6, the second measuring cylinder 8, the third measuring cylinder 10 and the fourth measuring cylinder 14 to move towards the rectangular opening 13 together through the disc 22 and the third connecting rod 24. For the measuring cylinder separated from the discharging port of the material bucket 3, the first rectangular plate 7 on the outer wall of its upper end contacts the discharging port of the material bucket 3 in time to block the material. When the measuring cylinder moves above the rectangular opening 13, the baffle 15 at the bottom of the measuring cylinder automatically rotates and opens along the second rectangular plate 26 through the first connecting rod 12 because there is no support from the workbench 1, thus completing automatic discharging. Through the interaction of the above components, not only can quantitative discharging be achieved each time, but also the measuring cylinder for holding the material can be switched according to the required usage amount, so as to achieve quantitative discharging of different measuring cylinders, greatly improving the scope of use.
