AI Technical Summary
When the material layer is thick, the weight of the material causes blockage between the scrapers in large annular drag chain leaching machines, especially at the discharge or outlet where material residue is likely to occur.
Design a discharge mechanism for an extractor, including a discharge plate and a top plate. The top plate is rotated by a scraper, which causes the upper part of the discharge plate to rotate downward, applying a downward force to facilitate rapid material discharge. The rotation angle is limited by a limit block to prevent material blockage.
It enables rapid material discharge, avoids material blockage between scrapers, ensures smooth material discharge, and improves production efficiency.

TECHNICAL FIELD
[0001] The utility model relates to extraction equipment technical field, especially point to a kind of discharge mechanism for leaching device. BACKGROUND
[0002] For the production capacity reaches 600t / d above Large annular drag chain leaching device, material layer thickness is above 0.85 meter, and the thickness of material layer is usually higher than the height of scraper, that is, there will be a certain thickness of material on the upper end of scraper, due to heavy material layer and oil extraction, etc., material layer becomes dense, and in the material falling place or discharge place, material is discharged by its own weight, and the problem of blocking between adjacent two scrapers and material residue is prone to occur. SUMMARY
[0003] The utility model provides a kind of discharge mechanism for leaching device, it is convenient to quickly material, avoid the blocking between two scrapers.
[0004] The technical scheme of the utility model is as follows: a kind of discharge mechanism for leaching device, including the material falling plate being arranged on the upper side of the scraper of leaching device, the material falling plate is hinged with the box body of leaching device, the right side of the lower end of material falling plate is provided with top plate, the material falling plate is perpendicular to top plate, the upper end length of material falling plate is greater than lower end, the weight of the lower end of material falling plate and top plate is greater than the upper end of material falling plate, when the left side of the scraper of leaching device pushes top plate and rotates upward, the upper end of material falling plate rotates downward, and the material on the right side of the scraper of leaching device is pushed and moves downward.
[0005] Further, the lower end of material falling plate is hinged with top plate by pivot, and torsional spring is sleeved on the pivot.
[0006] Further, limit block is also fixed on the inner wall of box body, and the limit block is located at the left side of the upper end of material falling plate, to limit the rotation angle of the upper end of material falling plate.
[0007] The utility model has the advantages of:
[0008] The utility model cooperates with the scraper and discharge mechanism, with the movement of the scraper, the upper end of material falling plate is swung downward by the scraper through top plate, downward force is exerted on the material on the right side of the scraper, so as to facilitate quick material, avoid the blocking between two scrapers. And the weight of the lower end of material falling plate and top plate is greater than the upper end of material falling plate, so as to facilitate the automatic reset of material falling plate.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Example 1
[0015] like Figure 1 and 2 As shown, the leaching device includes a housing 1, and a drive ring-shaped drag chain 2 is installed inside the housing. Scrapers 3 are evenly distributed on the ring-shaped drag chain 2. The ring-shaped drag chain 2 drives the scrapers 3 to move, and the scrapers 3 push the material to be leached to move. This part of the structure belongs to the prior art.
[0016] A discharge mechanism for a leaching machine includes a discharge plate 4, which is located above a scraper 3 and hinged to the leaching machine housing 1. The upper end of the discharge plate 4 is longer than the lower end, meaning the hinge point between the discharge plate 4 and the housing 1 is near the lower end of the discharge plate 4. A top plate 5 is fixed to the lower end of the discharge plate 4, perpendicular to the discharge plate 4 and located to the right of the lower end of the discharge plate 4. The weight of the lower end of the discharge plate 4 and the top plate 5 is greater than the upper end of the discharge plate 4. When the discharge plate 4 is not in contact with the scraper 3, the end of the discharge plate 4 closest to the top plate 5 faces downwards.
[0017] The discharge mechanism is installed at the material inlet or outlet of the box. The annular drag chain 2 drives the scraper 3 to move. When the left side of the scraper 3 pushes the top plate 5 to rotate upward, the upper end of the material discharge plate 4 rotates downward, pushing the material on the right side of the scraper 3 to discharge, thus avoiding material blockage. A limit block 6 is also fixed on the inner wall of the box 1. The limit block 6 is located on the left side of the upper end of the material discharge plate 4 and is used to limit the rotation angle of the upper end of the material discharge plate 4.
[0018] Example 2
[0019] This embodiment is basically the same as Embodiment 1, except that: Figure 2As shown, the lower end of the blanking plate 4 is hinged with the top plate 5 through the rotating shaft 7, and a torsion spring is sleeved on the rotating shaft 7. The top plate 5 is connected with the blanking plate 4 through the rotating shaft 7 and the torsion spring. When the upper end of the blanking plate 4 is blocked downward and exceeds the set value, the scraper 3 can push the top plate 5 to rotate, so as to pass over the top plate 5 and avoid damaging the parts.
[0020] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
