DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] By providing a ladle sand adding device in the embodiments of the present application, the problems of traditional sand adding methods, such as manual feeding or simple conduit sand adding devices, are solved. The sand adding speed is relatively slow. During the sand adding process, since the operator is relatively close to the ladle, if too close to the upper edge of the ladle, it is easy to cause burns to the operator's face. During the sand adding process, if the sand adding position is inaccurate, it will also lead to waste of sand material, which is not conducive to the economical use of the drainage sand and cannot meet the usage requirements.

[0022] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0023] Embodiments of the present utility model disclose a ladle sand adding device. As shown in the attached Figures 1-3 figures, it includes a support base 1. Universal wheels 101 are provided at the bottom of the support base 1. Through the design of the universal wheels 101, the overall device is convenient to move, so it is convenient to add sand to the inside of the ladle.

[0024] A short column 2 and a long column 3 are fixedly connected to the support base 1. The tops of the short column 2 and the long column 3 are fixedly connected to a conveying cylinder 4. The heights of the short column 2 and the long column 3 are different, so that the conveying cylinder 4 is designed to be inclined, which is convenient for sand adding and conveying from a low place to a high place. A screw rod 402 is provided inside the conveying cylinder 4. A motor main body 401 is fixedly connected to the conveying cylinder 4. The output end of the motor main body 401 is fixedly connected to the screw rod 402.

[0025] Through the design of the motor main body 401 and the screw rod 402, it is convenient to convey the materials inside the conveying cylinder 4, so that the materials are conveyed to the upper end of the conveying cylinder 4 for sand material addition. When the motor main body 401 works, it drives the screw rod 402 to rotate, and the screw rod 402 is used to convey the materials from a low place to a high place.

[0026] A feed hopper 403 is fixedly connected to the conveying cylinder 4. A horizontal extension pipe 5 is fixedly connected to the conveying cylinder 4. Through the design of the feed hopper 403, it is convenient to feed the sand material into the conveying cylinder 4. Through the design of the horizontal extension pipe 5, after the sand material is lifted, it is convenient to align the horizontal extension pipe 5 with the ladle for addition.

[0027] A limiting mechanism 6 is provided on the long vertical column 3. The limiting mechanism 6 includes a support base 601 fixedly connected to the long vertical column 3. An adjusting rod 602 is movably clamped on the support base 601. A pressing block 603 is fixedly connected to the adjusting rod 602. A lead screw 604 is threadedly connected to the long vertical column 3. The lead screw 604 is rotatably connected to the pressing block 603. A rotating handle 605 is fixedly connected to the lead screw 604;

[0028] Through the design of the limiting mechanism 6, when adding sand to the ladle, it is convenient to limit the position of the feeding landing point and the ladle by adjusting the position of the pressing block 603. Therefore, when adding materials, making the pressing block 603 fit against the side of the ladle can achieve limited feeding and ensure the accuracy of the feeding position each time;

[0029] When adjusting the position of the pressing block 603, directly rotate the lead screw 604. The operation is simple and convenient. When the lead screw 604 rotates, it pushes the pressing block 603 to move, and the pressing block 603 drives the adjusting rod 602 to slide along the support base 601.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
