[0007] The present invention can be realized by the following technical solutions: A buffer type material guiding trough for a sintering machine includes a base, a material guiding plate, and two side baffles symmetrically fixed on the top of the base. A buffer block is detachably connected between the two side baffles. The buffer block is composed of a rectangular shell and a rectangular plate. A first strip-shaped plate is slidably connected to the bottom of the rectangular shell, and a plurality of partition plates are equidistantly fixed on the side wall of the first strip-shaped plate.

[0024] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will describe in detail the specific embodiments, structures, features and their effects of the present invention with reference to the accompanying drawings and preferred embodiments.

[0025] Please refer to Figures 1 - 6As shown in the figure, a buffer type material guiding trough for a sintering machine includes a base 1. A material guiding plate 2 is fixedly connected to the top of the base 1. Two side baffles 3 are symmetrically and fixedly connected to the front and rear sides of the top of the material guiding plate 2. The side baffles 3 mainly function to block materials. A baffle 4 is fixedly connected to the left side of the top of the material guiding plate 2, and the baffle 4 is also mainly used to block materials. The right side of the top of the material guiding plate 2 is in an open state. During use, the sintered cake is conveyed above the material guiding plate 2 on the trolley on one side of the sintering machine, and the sintered cake falls onto the material guiding plate 2. The sintered cake is conveyed by the material guiding plate 2 between the rotating roller teeth and the rear flat plate of the single-roll crusher to achieve the crushing of the sintered cake.

[0026] A buffer block 5 is detachably connected between the two side baffles 3. Guide plates 6 are fixedly connected to the two sides of the buffer block 5 in contact with the side baffles 3. Guide grooves are provided at the corresponding positions of the side baffles 3 for the guide plates 6. The guide plates 6 and the guide grooves are in a sliding fit state. A connecting plate 7 is also fixedly connected to the side of the buffer block 5 where the guide plates 6 are provided. One side of the connecting plate 7 is connected to the side baffle 3 by screws. When installing the buffer block 5, first place the buffer block 5 between the two side baffles 3 and insert the guide plates 6 into the guide grooves. Then push the annular plate towards the direction close to the material guiding plate 2 until the bottom of the guide plate 6 contacts the bottom of the guide groove. At this time, there is still a certain distance between the buffer block 5 and the material guiding plate 2 for discharging the sintered cake. Then use screws to fix the connecting plate 7 to the side baffle 3. At this time, both sides of the buffer block 5 are in close contact with the inner wall of the side baffle 3, which is very convenient for installing the buffer block 5.

[0027] The buffer block 5 includes a rectangular housing 8 and a rectangular plate 9. A plurality of guide rods 10 are fixedly connected to one side of the rectangular plate 9. The other ends of the guide rods 10 penetrate and are slidably connected to the rectangular housing 8. A first plate 11 is slidably connected inside the rectangular housing 8. One side of the first plate 11 is fixedly connected to the guide rods 10, and the other side is fixedly connected to a plurality of first springs 12. The other ends of the first springs 12 are fixedly connected to the inner wall of the rectangular housing 8; an elastic cloth 13 is fixedly connected between the rectangular housing 8 and the rectangular plate 9 to prevent sundries from entering between the rectangular plate 9 and the rectangular housing 8. An anti-slip and wear-resistant rubber layer 14 is fixedly connected to the inner wall of the rectangular housing 8; during use, when the sintered cake falls, the sintered cake will directly fall on the rectangular plate 9, realizing the impact on the rectangular plate 9, reducing the distance between the rectangular plate 9 and the rectangular housing 8. At the same time, the guide rods 10 drive the first plate 11 to slide inside the rectangular housing 8, causing the first springs 12 to be compressed. Since the first plate 11 will rub against the anti-slip and wear-resistant rubber layer 14 when sliding along the inner wall of the rectangular housing 8, part of the energy is converted into heat and dissipated. Therefore, the buffer block 5 has a shock-absorbing effect, can reduce the vibration of the entire device, and improve the service life of the device; since the sintered cake does not directly fall on the material guiding plate 2, but first passes through the buffer of the buffer block 5 and then falls on the material guiding plate 2, it can reduce the damage to the material guiding plate 2 and improve the service life of the material guiding plate 2. Moreover, the buffer block 5 is detachable, which is convenient for replacement.

[0028] The material of the first spring 12 is alloy steel and is treated by spray coating, with good weather resistance, effectively increasing the service life and having good shock-proof effect.

[0029] A first strip-shaped plate 15 is slidably connected to one side of the rectangular housing 8 close to the material guiding plate 2. A plurality of partition plates 16 are fixedly connected at equal intervals on the side of the first strip-shaped plate 15 away from the rectangular housing 8. A straight rod 17 is fixedly connected to the other side, and the other end of the straight rod 17 is fixedly connected to a second strip-shaped plate 18. Second springs 19 are fixedly connected to both sides of the second strip-shaped plate 18; a first trapezoidal block 20 is fixedly connected to the bottom of the first plate 11, and a second trapezoidal block 21 is fixedly connected to the top of the second strip-shaped plate 18. The inclined surfaces of the first trapezoidal block 20 and the second trapezoidal block 21 are parallel to each other; the arrangement of the plurality of partition plates 16 enables the sintered cake to slide down from different positions of the material guiding plate 2, avoiding a very serious scratch at a certain place on the surface of the material guiding plate 2 while having fewer scratches at other positions; when the first plate 11 squeezes the first springs 12, it will cause the first trapezoidal block 20 to squeeze the second trapezoidal block 21, causing the second trapezoidal block 21 to drive the second strip-shaped plate 18 to slide slightly. When the first plate 11 retracts to the initial position, the second springs 19 will also cause the second strip-shaped plate 18 to retract to the initial position. Then the first strip-shaped plate 15 will drive the partition plates 16 to shake, avoiding the accumulation of the sintered cake and preventing the sintered cake from blocking the gap between the rectangular housing 8 and the material guiding plate 2.

[0030] A two-way screw rod 22 is also rotatably connected between the outsides of the two side baffles 3. The two-way screw rod 22 is driven by a motor. Slide plates 23 are sleeved at both ends of the two-way screw rod 22. A through groove 24 is formed at the bottom of the material baffle 4. Two scraping plates 25 are slidably arranged on the top of the material guiding plate 2. One side of the scraping plate 25 penetrates through the through groove 24 and is fixedly connected with the slide plate 23. During use, the motor drives the two-way screw rod 22 to rotate, so that the two-way screw rod 22 drives the slide plates 23 to move towards or away from each other, and further enables the two scraping plates 25 to clean the residues on the surface of the material guiding plate 2, avoiding a large amount of residues adhering to the surface of the material guiding plate 2.

[0031] In order to prevent the material from flowing out through the through groove 24, a U-shaped plate 26 is slidably arranged on the top of the material baffle 4. When the sintered cake falls, the bottom of the U-shaped plate 26 is at the lowest position, which can block most of the through groove 24. One side of the U-shaped plate 26 located above the slide plate 23 is fixedly connected with a third trapezoidal block 27, and the top of the slide plate 23 is fixedly connected with a fourth trapezoidal block 28. The inclined surfaces of the third trapezoidal block 27 and the fourth trapezoidal block 28 are parallel to each other. There are gaps between the U-shaped plate 26 and the two scraping plates 25, facilitating the cleaning of the residues on the surface of the material guiding plate 2 by the scraping plates 25 when the U-shaped plate 26 moves upward to an appropriate position. When the motor drives the two-way screw rod 22 to rotate, the slide plate 23 will drive the fourth trapezoidal block 28 to move, so that the fourth trapezoidal block 28 presses the third trapezoidal block 27, and then the U-shaped plate 26 moves upward. At this time, the U-shaped plate 26 will not block the relative movement of the scraping plates 25, ensuring the cleaning effect of the scraping plates 25 on the material guiding plate 2.

[0032] When the present invention is in use, the sintered cake on the trolley on one side of the sintering machine is conveyed above the material guiding plate 2, and the sintered cake falls onto the material guiding plate 2. During the falling process of the sintered cake, the sintered cake will directly fall on the rectangular plate 9, realizing the impact on the rectangular plate 9, so that the distance between the rectangular plate 9 and the rectangular housing 8 is reduced. At the same time, the guide rod 10 drives the first plate 11 to slide inside the rectangular housing 8, so that the first spring 12 is compressed. Since the first plate 11 will rub against the anti-slip and wear-resistant rubber layer 14 when sliding along the inner wall of the rectangular housing 8, part of the energy is converted into heat and dissipated. Therefore, the buffer block 5 has a shock-absorbing effect, which can reduce the vibration of the whole equipment and improve the service life of the equipment. Since the sintered cake does not directly fall on the material guiding plate 2, but first passes through the buffer of the buffer block 5 and then falls on the material guiding plate 2, it can reduce the damage to the material guiding plate 2 and improve the service life of the material guiding plate 2. Moreover, the buffer block 5 is detachable, which is convenient for replacement. When the first plate 11 squeezes the first spring 12, the first trapezoidal block 20 will squeeze the second trapezoidal block 21, so that the second trapezoidal block 21 drives the second strip plate 18 to slide slightly. When the first plate 11 retreats to the initial position, the second spring 19 will also make the second strip plate 18 retreat to the initial position. Then the first strip plate 15 will drive the partition plate 16 to shake, avoiding the accumulation of sintered cakes and preventing the sintered cakes from blocking in the gap between the rectangular housing 8 and the material guiding plate 2. By driving the bidirectional screw 22 to rotate through the motor, the bidirectional screw 22 drives the slide plate 23 to move towards each other, which will make the slide plate 23 drive the fourth trapezoidal block 28 to move, so that the fourth trapezoidal block 28 squeezes the third trapezoidal block 27, and then makes the U-shaped plate 26 move upward. At this time, the U-shaped plate 26 will not block the opposite movement of the scraper 25. By driving the slide plate 23 to move towards each other or away from each other through the bidirectional screw 22, the two scrapers 25 can clean the residue on the surface of the material guiding plate 2, avoiding a large amount of residue adhering to the surface of the material guiding plate 2.

[0033] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to it as an equivalent embodiment within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
