Figure 3 As shown, the material valve assembly 2 includes a circular upper baffle 21 and a circular lower baffle 22 arranged in parallel, the upper baffle 21 and the lower baffle 22 are connected by a plurality of connecting rods 23, the diameters of the upper baffle 21 and the lower baffle 22 are both larger than the diameter of the discharge port 14, the upper baffle 21 is arranged inside the feeding box 1, and the lower baffle 22 is arranged outside the feeding box 1.

[0026] Example 3

[0027] The utility model is a non-powered automatic feeding device, the structure of which is as follows Figure 1 As shown, it includes a feeding box 1, and a material valve assembly 2 is connected to the bottom of the feeding box 1. Figure 2 As shown, the upper part of the feeding box 1 is a cylindrical structure, and the lower part is a conical structure. The outer wall of the upper part of the feeding box 1 is provided with a plurality of lifting ears 11, and a filter screen 12 is provided inside. The filter screen 12 is placed on a filter screen bracket 13, and a discharge port 14 is provided at the bottom of the feeding box 1.

[0028] like Figure 3 As shown, the material valve assembly 2 includes a circular upper baffle 21 and a circular lower baffle 22 arranged in parallel, and the two are connected by a plurality of connecting rods 23, and the two ends of the connecting rods 23 are respectively threadedly connected to the upper baffle 21 and the lower baffle 22. A conical push barrel 24 is fixedly connected to the upper baffle 21, and a sealing ring a25 is installed at the lower part. Figure 4 As shown, two semicircular discharge ports 26 are arranged in the middle of the lower baffle 22, and a threaded hole is arranged in the cross beam plate between the two semicircular discharge ports 26, through which the connecting rod 23 is connected to the lower baffle 22. A shock absorbing ring 27 is installed above the lower baffle 22, and an annular counterweight block 28 and a sealing ring b29 are installed in sequence from top to bottom below.

[0029] like Figure 1 As shown, the upper baffle 21 of the material valve assembly 2 is inserted into the discharge port 14, and its diameter is larger than the diameter of the discharge port 14. It can contact the discharge port 14 and seal with the discharge port 14 through the sealing ring a25 to prevent the material in the feeding box 1 from flowing out through the discharge port 14. The diameter of the lower baffle 22 is also larger than the diameter of the discharge port 14, and it is arranged outside the feeding box 1.

[0030] The working process of the feeding device of the utility model is as follows:

[0031] like Figure 5As shown in the solid line, during the feeding operation, the feeding box 1 is filled with materials, and the overhead crane lifts the feeding box 1 through the lifting lug 11. At this time, the upper baffle 21 is tightly fitted with the discharge port 14, and the material valve assembly 2 is in a closed state, and the material in the feeding box 1 will not flow out. The overhead crane drives the feeding box 1 to descend, and when the sealing ring b29 at the bottom of the material valve assembly 2 contacts the feeding port of the raw material box 3, the material valve assembly 2 stops descending, but the feeding box 1 is still descending. At this time, a gap is generated between the upper baffle 21 and the discharge port 14, and the material begins to flow from the gap to the semicircular discharge port 26 of the lower baffle 22, and enters the raw material box 3 through the semicircular discharge port 26, as shown in FIG. Figure 5 As shown in the dotted line, when the feeding box 1 descends to the discharge port 14 and contacts the shock absorbing ring 27 on the lower baffle 22, the material valve assembly 2 is fully opened and the material begins to be fully discharged. The conical push barrel 24 can prevent the material from accumulating on the upper baffle 21, thereby accelerating the discharge speed. After the feeding is completed, the overhead crane lifts the feeding box 1 to complete the feeding operation.
