DETAILED DESCRIPTION
[0021] In order to more clearly understand the technical scheme of the utility model, the utility model is further described below in combination with the drawings.
[0022] As Figures 1-4 Indicated, a kind of with buffering function's discharging chute, including feed hopper 100 and chute body 200, feed hopper 100 side is provided with feed inlet 101, feed hopper 100 below is connected with chute body 200, the lower end of chute body 200 is provided with discharge port 201, the opposite side of the feed inlet 101 below of chute body 200 in the inner wall of chute body 200 is provided with first buffer mechanism 300 connection, the opposite side of the first buffer mechanism 300 below of chute body 200 in the inner wall of chute body 200 is provided with second buffer mechanism 400, first buffer mechanism 300 is used to buffer the impact of material that enters through feed inlet 101 by conveyer belt, second buffer mechanism 400 is used to buffer the impact of material after the action of first buffer mechanism 300;
[0023] Specifically, in the embodiment, the first buffering mechanism 300 comprises a first buffering plate 301, a first connecting rod 302, a first spring 303, and a first connecting block 304. The first buffering plate 301 is arranged obliquely below the opposite side of the feeding port 101 in the chute body 200. The first buffering plate 301 and the inner wall of the chute body 200 on the side where the first buffering plate 301 is arranged are spaced apart to allow the first buffering plate 301 to move horizontally. The first connecting rod 302 is arranged horizontally and at least one first connecting rod 302 is arranged. One end of the first connecting rod 302 is detachably connected to the back of the first buffering plate 301, and the other end of the first connecting rod 302 penetrates through the first connecting block 304 fixed to the inner wall of the chute body 200 and extends out of the chute body 200. The first connecting rod 302 is slidable in the first connecting block 304. The end of the connecting rod extending out of the chute body 200 is fixed with a limiting block 3021. The first spring 303 is sleeved on the first connecting rod 302 between the first buffering plate 301 and the first connecting block 304. In use, the material is conveyed from the conveying belt at the feeding port 101 into the chute body 200. The material has a certain horizontal initial speed and falls freely. Because the material has a horizontal initial speed, the material moves forward, i.e., moves to the installation position of the first buffering mechanism 300 on the opposite side of the feeding port 101. At this time, the height difference between the feeding port 101 and the first buffering mechanism 300 is not large, and the impact of the material on the first buffering plate is mainly from the horizontal direction. After the first buffering plate 301 is impacted in the vertical direction, the first buffering plate 301 moves in the direction of the side wall of the chute body 200. The first connecting rod 302 slides in the first connecting block 304, so that the first spring 303 is compressed. After the material is buffered by the first buffering plate 301, most of the material falls along the inclined surface of the first buffering plate 301.
[0024] Preferably, in the embodiment, the first connecting rod 302 is provided with two first connecting rods. The two connecting rods can enhance the stability of the first buffering mechanism 300 as a whole, and mainly enhance the connection of the first buffering plate 301. Two connecting rods are provided with two first springs 303, which can also improve the buffering effect.
[0025] Preferably, in the embodiment, a first wear-resistant rubber plate 305 is attached to the upper surface of the first buffering plate 301. The first wear-resistant rubber plate 305 can not only protect the first buffering plate 301, but also has a certain buffering effect. When the first wear-resistant rubber plate 305 is severely worn, only the first wear-resistant rubber plate 305 needs to be replaced.
[0026] Preferably, in the embodiment, a second wear-resistant rubber plate 306 is arranged in the space between the first buffering plate 301 and the inner wall of the chute body 200. The upper part of the second wear-resistant rubber plate 306 is fixed to the inner wall of the chute body 200. The second wear-resistant rubber plate 306 can prevent the material from entering the space and affecting the operation of the first buffering plate 301.
[0027] Specifically, in the embodiment, the second buffering mechanism 400 comprises a second buffering plate 401, a second connecting rod 402, a second spring 403, a second connecting block 404, a guide rod 405, an upper fixing plate 406 and a lower fixing plate 407. The second buffering plate 401 is obliquely arranged on the opposite side of the chute body 200 below the first buffering mechanism 300. The second buffering plate 401 leaves a gap for vertical movement with the inner wall of the chute body 200 on the side thereof. The second connecting rod 402 is horizontally arranged and at least one is provided. One end of the second connecting rod 402 is detachably connected with the back of the second buffering plate 401, and the other end is fixedly connected with the second connecting block 404. The second connecting block 404 is slidably arranged on the side wall of the chute body 200. The guide rod 405 vertically penetrates through the second connecting block 404. The upper end of the guide rod 405 is fixed on the upper fixing plate 406, and the lower end of the guide rod 405 is fixed on the lower fixing plate 407. The upper fixing plate 406 and the lower fixing plate 407 are both fixed on the side wall of the chute body 200. The second spring 403 is sleeved on the guide rod 405 between the second connecting block 404 and the lower fixing plate 407. When in use, after the material is buffered by the first buffering mechanism 300, the material continues to fall inside the chute body 200. Since the first buffering plate 301 is obliquely arranged, the material will move to the opposite side of the first buffering plate 301, i.e. to the second buffering mechanism 400, after falling. Since the horizontal speed of the material after being affected by the first buffering plate 301 is greatly reduced, the material takes a longer time to reach the second buffering mechanism 400 on the opposite side than to reach the first buffering mechanism 300 from the feeding port 101, i.e. the height difference between the first buffering mechanism 300 and the first buffering mechanism 300 is large. The length of the chute body 200 is generally 2-3 meters. When the material reaches the second buffering plate 401, the impact on the second buffering plate 401 is mainly in the vertical direction. In the design, the inclination angle of the second buffering plate 401, i.e. the included angle between the second buffering plate 401 and the side wall on the side thereof, can be increased, which is more beneficial to receiving the impact of the material and strengthening the buffering effect. When the material falls on the second buffering plate 401, the second buffering plate 401 will move downward in the horizontal direction, the second connecting block 404 moves downward along the guide rod 405, and the second spring 403 is compressed. Then, under the elastic force of the second spring 403, the second connecting block 404 is reset upward, the second buffering plate 401 continues to receive the impact of the material, and the buffering is repeated. Finally, the material is buffered by the first buffering plate 301 and falls to the conveying belt at the discharge port 201, which protects the inner wall of the chute body 200 from being severely worn due to a large impact, allows the material to smoothly and stably fall on the conveying belt at the discharge port 201, greatly reduces the impact between the materials and the generation of dust, improves the working environment, and improves the material quality.
[0028] Preferably, in the embodiment, the second connecting block 404 comprises a block one 4041, a connecting sliding block 4043 and a block two 4042, the block one 4041 is located in the chute body 200, the block two 4042 is located outside the chute body 200, the connecting sliding block 4043 is fixedly connected with the block one 4041 on one side and fixedly connected with the block two 4042 on the other side, a sliding groove 202 matched with the connecting sliding block 4043 is arranged on the side wall of the chute body 200, and the guide rod 405 vertically penetrates through the block two 4042, the block one 4041 and the block two 4042 are arranged, and the block two 4042 is arranged outside the chute body 200, so that the guide rod 405 and the second spring 403 are all arranged outside the chute body 200, and the working of the components is not affected by the materials in the chute body 200.
[0029] Preferably, in the embodiment, the second connecting rod 402 is provided with two;
[0030] Preferably, in the embodiment, a third wear-resistant rubber plate 408 is attached to the upper surface of the second buffer plate 401.
[0031] Preferably, in the embodiment, a fourth wear-resistant rubber plate 409 is arranged at the gap between the second buffer plate 401 and the inner wall of the chute body 200, and the upper portion of the fourth wear-resistant rubber plate 409 is fixed on the inner wall of the chute body 200.
[0032] Working principle: when in use, the materials enter the chute body 200 from the conveying belt at the feeding port 101, the materials fall freely with a certain horizontal initial speed, the first buffer plate 301 is impacted and then moves in the direction of the side wall of the chute body 200, the first connecting rod 302 slides in the first connecting block 304, and the first spring 303 is compressed, most of the materials fall along the inclined surface of the first buffer plate 301 after being buffered by the first buffer plate 301, the second buffer plate 401 moves downward in the horizontal direction, the second connecting block 404 moves downward along the direction of the guide rod 405 and compresses the second spring 403, then the second connecting block 404 is reset upward under the elastic force of the second spring 403, the second buffer plate 401 continues to be impacted by the materials, and the buffering is repeated, and finally the materials fall to the conveying belt at the discharging port 201 through the first buffer plate 301, so that the inner wall of the chute body 200 is protected from serious wear caused by a large impact, the materials can be stably and gently dropped on the conveying belt at the discharging port 201, the impact between the materials is reduced, the generation of dust is reduced, the working environment is improved, and the material quality is improved.
