Description

Technical Field

[0001] This utility model relates to the field of coal preparation machine feed hopper technology, specifically a feed device with buffer function. Background Technology

[0002] In the coal industry, coal preparation technology has been widely developed, and coal preparation machines play a key role in the entire coal sorting process. The feed hopper is an important component of the coal preparation machine. In practical applications, the material entering the feed hopper of a traditional coal preparation machine often has a large impact force, and the structure of the feed hopper is difficult to effectively buffer it. This not only easily leads to damage to the feed hopper body due to frequent impacts, but also shortens the service life of the equipment and increases maintenance costs and downtime.

[0003] Chinese Utility Model Patent Publication No. CN 211469868 U discloses a coal hopper that can effectively control the material flow trajectory. The material flows slowly down a curved surface and exits through the outlet onto a conveyor belt. The conveyor belt experiences less stress, which reduces dust generation. Furthermore, a large amount of coal does not accumulate at the outlet, and the conveyor belt transports coal evenly. The material is guided to flow slowly down a curved surface with gradually increasing slope formed by the inner sides of the first, second, and third guide plates. Although this can reduce the impact force of the material to a certain extent, the buffering force for the falling coal is not adjustable. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a feeding device with a buffer function, which can effectively solve the problems in the prior art.

An adjusting plate is located between the rotating plate and the buffer plate. A spring is sleeved on the outer side of the second guide rod. The top of the rotating plate and the top of the buffer plate are fixedly connected by a dust-proof plate.

[0007] Preferably, the fixing component includes a fixing seat, a placement groove, a locking plate, a locking groove, and a limiting pin. The upper end of the fixing seat has a placement groove, the upper end of the fixing seat is rotatably connected to the locking plate, the lower end of the locking plate has a locking groove, and the fixing seat and the locking plate are fixed by insertion of the limiting pin.

[0008] Through the above technical solution, the feeding hopper body can be conveniently and securely fixed to the conveyor belt by means of the placement groove on the fixed seat in the fixing component, the locking plate of the rotating connection, and the cooperation of the locking groove and the limiting pin.

[0009] Preferably, the positioning rod is adapted to both the placement groove and the locking groove.

The installation process is simple and convenient, and the relative position of the conveyor belt and the feed hopper body is fixed accurately after installation, ensuring that the material can smoothly enter the feed hopper body from the conveyor belt, reducing material spillage and improving the efficiency of material conveying and feeding.

[0011] Preferably, the rotating shaft is rotatably connected to the feed hopper body, and the guide shaft is adapted to the guide groove.

[0012] Through the above technical solution, the rotating shaft is rotatably connected to the feed hopper body, and the rotating plate can rotate around the rotating shaft as the center, thereby adjusting the angle of the buffer plate to adapt to different feeding conditions; the guide shaft is matched with the guide groove, and during the rotation of the rotating plate, the guide shaft slides in the guide groove, which plays a good guiding role, ensuring the stability and accuracy of the rotation of the rotating plate, and thus enabling the buffer plate to better play its buffering role.

[0013] Preferably, the slider and the groove are slidably connected, and the slider and the screw are threadedly connected.

[0019] Compared with the prior art, the present invention provides a feeding device with a buffer function, which has the following beneficial effects:

[0020] 1. This feeding device with buffer function can adjust the compression of the spring by adjusting the adjustment plate when the second motor drives the lead screw to rotate, thereby changing the buffering force of the buffer plate to meet the buffering requirements of the feeding speed. When the first motor drives the screw to rotate, the slider can move smoothly in a straight line along the axial direction of the screw in the groove.

[0032] The buffer assembly 6 includes a slide 601, a screw 602, a first motor 603, a slider 604, a connecting rod 605, a connecting block 606, a rotating plate 607, a rotating shaft 608, a guide shaft 609, a buffer plate 610, a first guide rod 611, a second motor 612, a lead screw 613, an adjusting plate 614, a second guide rod 615, and a spring 616. The center of the slide 601 is rotatably connected to the screw 602, and the upper end of the slide 601 is fixedly connected to the first motor 603. A slider 604 is provided on the side of the slide 601 near the screw 602. One end of the connecting rod 605 is rotatably connected to both sides of the slider 604, and the other end of the connecting rod 605 is rotatably connected to the connecting block 606. The connecting block 606 is located away from the slide 601. A rotating plate 607 is fixedly connected to one side of the rotating plate 607.

[0033] Specifically, the fixing component 3 includes a fixing base 301, a placement groove 302, a locking plate 303, a locking groove 304, and a limiting pin 305. The fixing base 301 has a placement groove 302 at its upper end, and the locking plate 303 is rotatably connected to the upper end of the fixing base 301. The locking plate 303 has a locking groove 304 at its lower end. The fixing base 301 and the locking plate 303 are fixed together by the limiting pin 305. The advantage is that, through the cooperation of the placement groove 302 on the fixing base 301, the rotatably connected locking plate 303, the locking groove 304, and the limiting pin 305 in the fixing component 3, the feed hopper body 1 can be easily and stably fixed and installed with the conveyor belt 9.

[0034] Specifically, the positioning rod 10 is compatible with both the placement groove 302 and the locking groove 304. The advantage is that the compatibility of the positioning rod 10 with both the placement groove 302 and the locking groove 304 allows the conveyor belt 9 to be precisely connected and installed with the feed hopper body 1. The installation process is simple and convenient, and the relative position of the conveyor belt 9 and the feed hopper body 1 is accurately fixed after installation, ensuring that materials can smoothly enter the feed hopper body 1 from the conveyor belt 9, reducing material spillage and improving the efficiency of material conveying and feeding.

[0035] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0036] Specifically, the rotating shaft 608 is rotatably connected to the feed hopper body 1, and the guide shaft 609 is adapted to the guide groove 5. The advantage is that the rotating shaft 608 is rotatably connected to the feed hopper body 1, allowing the rotating plate 607 to rotate around the rotating shaft 608 as the center, thereby adjusting the angle of the buffer plate 610 to adapt to different feeding conditions; the guide shaft 609 is adapted to the guide groove 5, and during the rotation of the rotating plate 607, the guide shaft 609 slides within the guide groove 5, providing good guidance and ensuring the smoothness and accuracy of the rotation of the rotating plate 607, thus enabling the buffer plate 610 to better perform its buffering function.

[0037] Specifically, slider 604 is slidably connected to groove 601, and slider 604 is threadedly connected to screw 602. The advantage is that when motor 603 drives screw 602 to rotate, slider 604 can move smoothly in a straight line along the axial direction of screw 602 within groove 601. The position of slider 604 can be precisely controlled, thereby accurately adjusting the positions of rotating plate 607 and buffer plate 610 via connecting rod 605 to meet different feeding buffering requirements.

[0038] Specifically, guide rod 611 and guide rod 615 are slidably connected to the rotating plate 607, guide rod 615 is slidably connected to the adjusting plate 614, and the adjusting plate 614 is threadedly connected to the lead screw 613. The spring 616 is fixedly connected to the buffer plate 610 and the adjusting plate 614 at both ends. The advantage is that when the motor 612 drives the lead screw 613 to rotate, the compression degree of the spring 616 can be adjusted through the adjusting plate 614, thereby changing the buffering force of the buffer plate 610 to adapt to the buffering requirements of the feeding speed. At the same time, guide rod 611 and guide rod 615 provide good guidance, ensuring the smooth movement of the buffer plate 610 during the buffering process and preventing it from shifting or shaking.

[0039] Specifically, buffer assembly 6 has the same structure as buffer assembly 7 and buffer assembly 8. Buffer assembly 7 is located below buffer assembly 6, and buffer assembly 8 has two identical symmetrical components. The advantage is that this creates a multi-layered, multi-angled buffer structure inside the feed hopper body 1, which effectively buffers the material entering the feed hopper, reducing the impact force during feeding and protecting the feed hopper body 1 from damage. It also improves the uniformity of material distribution within the feed hopper, which is beneficial for the smooth operation of subsequent wind-powered coal preparation.

[0040] Working principle: When in use, rotate to open the locking plate 303, place the positioning rod 10 of the conveyor belt 9 into the placement groove 302, rotate to close the locking plate 303, and use the limit pin 305 to insert and lock the fixing seat 301 into the placement groove 302. The conveyor belt 9 transports the material to the feeding hopper body 1. After the material enters the feeding hopper body 1, it first contacts the buffer component 6. The motor 603 starts and drives the screw 602 to rotate. The rotation of the screw 602 drives the slider 604 to move linearly in the groove 601. The movement of slider 604 pushes connecting block 606 through connecting rod 605, which in turn drives rotating plate 607 to rotate around rotating shaft 608. Guide shafts 609 on both sides of rotating plate 607 slide in guide groove 5 to ensure the smooth rotation of rotating plate 607, thereby adjusting the angle of buffer plate 610. Motor 2 612 starts to drive lead screw 613 to rotate. Since adjusting plate 614 is threadedly connected to lead screw 613, the rotation of lead screw 613 causes adjusting plate 614 to move on guide rod 2 615, thereby adjusting the compression degree of spring 616 and realizing the adjustment of buffering force of buffer plate 610. When the material impacts the buffer plate 610, the buffer plate 610 is buffered by the action of the spring 616 to reduce the impact force of the material. The second buffer component 7 is below the first buffer component 6 and continues to buffer the material after the first buffer. The two symmetrically arranged third buffer components 8 further buffer the material from both sides. After multi-level and multi-angle buffering, the material is evenly distributed in the feed hopper body 1 and then enters the coal preparation machine for subsequent coal preparation work.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
