However, the feed hoppers of existing and the above-mentioned slag dischargers are usually fixed on the slag discharger, which is not convenient for connecting with machines having slag discharge ports at different heights, resulting in certain limitations. Therefore, the present utility model is proposed. Content of the Utility Model

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] During the use of the slag discharging machine, a feed hopper is required. The feed hopper provided by the present invention is specifically used for lifting and receiving slag materials, making it convenient for this feed hopper to connect to the slag discharging ports with different heights on the body of the slag discharging machine, so as to discharge slag. During the use of this feed hopper, its height needs to be adjusted in advance to ensure the normal operation of the feed hopper.

[0020] As Figures 1 - 4 shown, the present invention provides a technical solution: a feed hopper for a slag discharging machine, including a slag discharging machine body 1. A feed component is provided at the top of the slag discharging machine body 1. The feed component includes a first vertical pipe 2 communicated with the top of the slag discharging machine body 1. A second vertical pipe 202 is slidably inserted in the upper part of the first vertical pipe 2. A third vertical pipe 205 is slidably inserted in the upper part of the second vertical pipe 202. A hopper body 207 is fixed at the top end of the third vertical pipe 205. A baffle pipe 208 is fixed at the top end of the hopper body 207. First limit blocks 201 are fixed on the upper parts of the four inner walls of the first vertical pipe 2. First vertical grooves 203 adapted to slide with the first limit blocks 201 are formed on the outer wall of the second vertical pipe 202. Second limit blocks 204 are fixed on the upper parts of the four inner walls of the second vertical pipe 202. Second vertical grooves 206 adapted to slide with the second limit blocks 204 are formed on the outer wall of the third vertical pipe 205. Arch-shaped plates 3 are symmetrically fixed on both sides of the first vertical pipe 2. A screw column 301 is rotatably inserted on the arch-shaped plate 3. A fixed column 302 is arranged on one side of the screw column 301, and the fixed column 302 is fixed to the arch-shaped plate 3. Fixed frame plates 303 are symmetrically fixed on the front and back sides of the first vertical pipe 2. Screw rods 304 are rotatably inserted on the fixed frame plates 303. Chain wheels are fixedly sleeved on both the screw rod 304 and the screw column 301. Among them, the first limit blocks 201, the second limit blocks 204, the first vertical grooves 203 and the second vertical grooves 206 play a role in limiting and stabilizing the lifting of the first vertical pipe 2, the second vertical pipe 202 and the third vertical pipe 205.

[0021] In an embodiment, a chain 305 is engaged between the sprockets. The chain 305 is used to drive the screw rod 304 and the stud 301 to rotate synchronously in the same direction. The bottom end of the stud 301 located on one side of the first vertical pipe 2 is connected to a driving motor. The driving motor is installed on the arched plate 3. A first sleeve 307 is sleeved on the stud 301, and a second sleeve 308 is sleeved on the fixed column 302. The tops of the first sleeve 307 and the second sleeve 308 located on the same side are fixed with a cross plate 306. The cross plate 306 is fixed to the outer wall of the edge guard pipe 208. Among them, the sprockets and the chain 305 are both prior arts, and the driving motor used is a servo motor with a self-locking function in the prior art.

[0022] In an embodiment, a thread groove adapted to the external thread of the stud 301 is formed in the first sleeve 307. The second sleeve 308 is slidably connected to the fixed column 302. The cross plate 306, the first sleeve 307, and the second sleeve 308 are integrated. By setting the feeding assembly, the driving motor is controlled to start, the stud 301 rotates, and the chain 305 drives a plurality of studs 301 and a plurality of screw rods 304 to rotate synchronously in the same direction. Thus, the cross plate 306, the first sleeve 307, the second sleeve 308, and the hopper body 207 are lifted as a whole, adjusting the overall height of the first vertical pipe 2, the second vertical pipe 202, the third vertical pipe 205, the hopper body 207, and the edge guard pipe 208, which is convenient for connecting to machines with slag discharge ports of different heights, and improving the applicability of the feeding hopper to a certain extent.

[0023] In an embodiment, a sleeve plate 4 is sleeved and fixed on the outer wall of the first vertical pipe 2. A vertical surrounding plate 401 is fixed on the outside of the sleeve plate 4. The vertical surrounding plate 401 is used to shield and protect the chain 305 and the sprockets. The fixed column 302 is fixed to the sleeve plate 4, and the stud 301 rotates relative to the sleeve plate 4. Among them, the sleeve plate 4 plays a certain limiting role on the first sleeve 307 and the second sleeve 308.

[0024] Working principle: When using this feeding hopper, place the slag discharge machine body 1 so that the hopper body 207 is located below the outlet where the slag discharge is required. Then control the driving motor to start. The driving motor drives the stud 301 connected thereto to rotate. Under the action of the sprockets and the chain 305, a plurality of studs 301 and a plurality of screw rods 304 rotate synchronously in the same direction. Thus, the third vertical pipe 205 and the hopper body 207 are lifted as a whole under the rotational limiting action of the cross plate 306, the first sleeve 307, and the second sleeve 308. At this time, the first limiting block 201 slides in the first vertical groove 203, and the second limiting block 204 slides in the second vertical groove 206 until the hopper body 207 rises to a suitable position and stops. The slag passes through the hopper body 207, the first vertical pipe 2, the second vertical pipe 202, and the third vertical pipe 205 and enters the slag discharge machine body 1.

[0025] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
