Description

Quartz sand filling hopper for foundry

Technical Field

The utility model relates to the technical field of transfer containers, in particular to a quartz sand filling hopper for a foundry.

Background

Quartz sand is a material used in large quantities by foundry, and is mainly used for making sand boxes. Generally, quartz sand can be used repeatedly, but before each use, the quartz sand is required to be subjected to crushing, grinding and deironing processes. Because quartz sand has the characteristics of high specific gravity, easy dust emission and the like, box-type tools such as a storage hopper and the like are used for the transfer process instead of woven bags. Compared with the storage hopper, the filling hopper is also provided with an opening at the bottom side so that quartz sand can directly enter the crusher and other equipment. Most of the existing filling hoppers have simple structure, and dust raising is easy to occur in the filling process. In addition, to automatically open and close the door at the bottom opening of the hopper, two switches are typically required, one to open and one to close. The mechanical complexity of the two control switches is relatively high and inconvenient to use.

Preferably, a cross brace is also fixed in the box body to support the side wall of the box body; the outside of the box body is also provided with a handrail for manual movement of the box body.

The quartz sand filling hopper for the foundry, which adopts the structure, is automatically opened when the filling hopper is in butt joint with the feeding port of the peripheral equipment, is automatically closed after the filling hopper contacts the ground, and is free from manual participation in the whole process, so that the control is simple and convenient. In addition, the charging hopper is directly in airtight butt joint with the feed inlet of the peripheral equipment, so that dust generation is effectively inhibited.

Detailed Description

The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.

As shown in the figure, the foundry uses the quartz sand to irrigate the hopper, the top side of the box 4 sets up parts such as the hoist and mount with the chain 1, handrail 2, cross brace 3, etc., and the inboard bottom of box 4 sets up the bucket form blanking plate 5. The box body 4 and the blanking plate 5 jointly enclose an annular cavity so as to butt-joint a feed inlet of peripheral equipment, thereby inhibiting dust generation in the blanking process. The top of the annular cavity can be filled with a sponge gasket 6 to ensure that the box body 4 is tightly abutted with a feed inlet of peripheral equipment.

The blanking plate 5 is composed of a first annular frame 51 in the horizontal direction, a bucket-shaped bin wall 52 and a second annular frame 53 in the vertical direction. Wherein, first ring frame 51 provides the horizontal plane for peripheral equipment's feed inlet butt joint to avoid box 4 and feed inlet to lead to the transition card and, also make things convenient for simultaneously follow-up lifting slide bar 8 because of the contained angle. The bottom of the second ring frame 53 is abutted against the hinge shaft of the door 9 by a transverse sleeve and ensures that the lower surface of the door 9 is aligned with the lower edge of the case 4 so that the door 9 is automatically and completely closed after contacting the ground. The door 9 extends outwards to extend out of the clamping edge 91 near the side direction of the annular cavity, and the clamping edge 91 has two functions, namely, the wedge block 82 on the slide rod 8 is convenient to limit, and the door 9 opening and closing angle is limited. To reduce the sand leakage of the door 9, a sealing block 92 may be further provided inside the door 9.

A longitudinal sleeve 7 is arranged below the blanking plate 5 along the blanking plate 5, and a sliding rod 8 is connected in a sliding manner in the longitudinal sleeve 7. The top of the slide bar 8 extends horizontally with a flange 81 so that the feed opening of the peripheral device lifts the slide bar 8 upwards. The bottom of the slide bar 8 is provided with a wedge block 82, and the wedge block 82 is used for being clamped between clamping edges 91 of the blanking plate 5.

When the quartz sand is filled, the bottom of the box body 4 directly contacts the ground, the carriage door 9 is completely closed at the moment, the sliding rod 8 slides down under the action of gravity and the wedge block 82 slides into an included angle between the carriage door 9 and the blanking plate 5. In the lifting process of the box body 4, the compartment door 9 of the box body 4 in a suspended state can still be tightly closed due to the limiting function of the wedge blocks 82. When the box 4 is docked with the feed inlet of the crusher (peripheral equipment), the feed inlet jacks up the wedge block 82, so that the compartment door 9 is naturally opened under the action of gravity and quartz sand pressure. After filling, in the process that the box body 4 gradually approaches the ground, the carriage door 9 is gradually closed under the ground abutting action, after the box body 4 is completely landed, the carriage door 9 is completely closed, and meanwhile, the wedge blocks 82 on the slide bars 8 are automatically limited. In addition, since the case 4 is provided with only one door 9, the falling process must be gradually closed, and it is impossible for the door 9 to be still in an open state after the case 4 falls to the ground.

The foregoing is a specific embodiment of the present utility model, but the scope of the present utility model should not be limited thereto. Any changes or substitutions that would be obvious to one skilled in the art are deemed to be within the scope of the present utility model, and the scope is defined by the appended claims.
