In order to achieve the above object, the utility model provides a following technical scheme: a cast molding sand unpowered on-demand discharging device comprises a hopper and a conveyor belt; the hopper is of a cylindrical structure with an open top, the bottom of the hopper is provided with a hopper bottom, the hopper bottom is surrounded by a conical surface with a cross section diameter continuously reduced from top to bottom, the hopper bottom is provided with a discharge port, a casting molding sand pile is piled below the discharge port, and the hopper is also provided with a hopper frame; the conveyer belt is equipped with the conveyer belt support, be equipped with the driven voller in the one end that the conveyer belt is close to the hopper, the conveyer belt is kept away from and is equipped with the drive roll in the one end of hopper, the drive roll links to each other with the motor, be equipped with the transport fill on the conveyer belt.

Preferably, the discharge hole is 50-100cm away from the ground.

Preferably, the number of the bucket frames is more than or equal to 3.

Preferably, the transfer hopper top diameter > bottom diameter.

Preferably, when the transfer bucket reaches the foundry sand pile, the side wall of the transfer bucket shovels the molding sand into the transfer bucket.

Compared with the prior art, the beneficial effects of the utility model are that: firstly, the structure is simple, the cost is low, and the realization is easy; secondly, utilize the casting sand to fall slowly automatic hindrance and continue the unloading, the casting sand is taken the back and is flowed the principle of filling the neat sand heap automatically, realizes the automatic supply of molding sand, does not need extra power consumption, is favorable to practicing thrift manufacturing cost.

Other features of the present disclosure and advantages thereof will become apparent from the following detailed description of exemplary embodiments thereof, which proceeds with reference to the accompanying drawings.

Drawings

In order to more clearly illustrate the embodiments of the present disclosure or technical solutions in related arts, the drawings used in the description of the embodiments or related arts will be briefly introduced below, it is obvious that the drawings in the following description are only embodiments of the present disclosure, and for those skilled in the art, other drawings can be obtained according to the provided drawings without creative efforts.

Fig. 1 is an overall schematic view of the present invention.

In the figure: 1. hopper, 2, conveyer belt, 3, bottom of the bucket, 4, casting molding sand heap, 5, bucket frame, 6, discharge gate, 7, driven voller, 8, transport fill, 9, drive roll, 10, motor, 11, conveyer belt support.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: a cast molding sand unpowered on-demand discharging device comprises a hopper 1 and a conveyor belt 2; the hopper 1 is of a cylindrical structure with an open top, a hopper bottom 3 is arranged at the bottom of the hopper 1, the hopper bottom 3 is formed by the enclosure of a conical surface with the diameter of a cross section gradually reduced from top to bottom, a discharge hole 6 is formed in the hopper bottom 3, the discharge hole 6 is 80cm away from the ground, a casting sand pile 4 is piled below the discharge hole 6, a hopper frame 5 is further arranged on the hopper 1, and the number of the hopper frames 5 is 4; conveyer belt 2 is equipped with conveyor belt support 11, be equipped with driven voller 7 in the one end that conveyer belt 2 is close to hopper 1, conveyer belt 2 is kept away from and is equipped with drive roll 9 in the one end of hopper 1, drive roll 9 links to each other with motor 10, be equipped with on conveyer belt 2 and transport fill 8, transport and fill 8 top diameter ratio bottom diameter and 20cm big, when transport and fill 8 reachs cast molding sand and pile 4, transport and fill 8 lateral walls with the type sand shovel in transporting fill 8.

The working principle is as follows: when the molding sand is stored in the hopper 1, the molding sand flows out of the discharge port 6, the support legs lift the discharge port 6 to a distance above the ground, so the molding sand flowing out of the discharge port 6 forms a casting molding sand pile 4 at the bottom of the discharge port 6, when the top of the casting molding sand pile 4 reaches the discharge port 6, the material flowing out of the discharge port 6 is blocked and kept in a blocking state, the discharging is stopped, when the casting molding sand pile is conveyed to the sand pile, the conveying hopper 8 carries a part of the molding sand away from the casting molding sand pile 4, due to the action of gravity, the top of the casting molding sand pile 4 descends due to the collapse of the sand pile, the blocking state of the discharge port 6 is changed into a smooth state, the molding sand falls, when the collapsing part is filled, the top of the casting molding sand pile 4 blocks the discharge port 6 again, the discharging is stopped, and the motor 10 of the conveyor belt 2 is started or closed according to the.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
