[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figures 1 to 6 As shown, the embodiment of the utility model provides a transfer hopper, including a feed box 2 and a discharge hopper 4. Among them:
[0025] The feed box 2 is provided with a pair of through holes for the feed pipe 3 to pass through, and the feed box 2 is installed at the discharge port of the feed pipe 3. The discharge hopper 4 is connected to the bottom of the feed box 2 and communicated with the feed box 2. The bottom of the discharge hopper 4 is provided with an outlet communicated with the discharge pipe 5, and a sealing plate 6 that can block the outlet and a limiter that limits the sliding of the sealing plate 6 are slidably installed on the discharge hopper 4.
[0026] Specifically, the feed pipe 3 is installed in the feed box 2 by passing through the perforation, and its discharge port is located in the feed box 2, so that the feed 12 of the feed pipe 3 can flow into the feed box 2 and the discharge hopper 4 through the discharge port, and then flow into the discharge pipe 5 through the outlet of the discharge hopper 4. Figure 5 As shown, the sliding position of the sealing plate 6 is changed from left to right in sequence and is fixed by a limiting member. Figure 5 The sealing plate 6 in the leftmost figure does not slide, and the outlet of the discharge hopper 4 is in a fully open state; Figure 5 The sealing plate 6 in the middle slides downward, making the outlet of the discharge hopper 4 smaller, and the feed entering the discharge pipe 5 becomes less; Figure 5 The sealing plate 6 in the rightmost figure continues to slide, so that the outlet of the discharge hopper 4 is closed, and the feed will no longer enter the discharge pipe 5.
[0027] As a preferred implementation, Figure 2 and Figure 3As shown, the discharge hopper 4 includes a first inclined plate 401 and a second inclined plate 402 that are arranged opposite to each other, and two side plates connected between the first inclined plate 401 and the second inclined plate 402. The first inclined plate 401, the second inclined plate 402, and the bottom of the two side plates enclose an outlet. The sealing plate 6 is slidably mounted on the first inclined plate 401 and can slide from top to bottom along the first inclined plate 401 to the second inclined plate 402, and forms a closed discharge hopper cavity with the first inclined plate 401, the second inclined plate 402, and the two side plates. The sealing plate 6 slides from top to bottom along the first inclined plate 401 to change the size of the outlet of the discharge hopper 4 until the sealing plate 6 slides to the second inclined plate 402, blocks the outlet, and forms a closed discharge hopper cavity.
[0028] As a preferred implementation, Figure 2 and Figure 3 As shown, the limiting member is a screw rod 7 connected to the sealing plate 6 and a long hole provided on the first inclined plate 401. The screw rod 7 is slidably connected in the long hole and is screwed with an adjusting nut 8. A fixing plate 9 for pressing the sealing plate 6 is provided above the sealing plate 6. The fixing plate 9 is connected to the first inclined plate 401 and is arranged along the length direction of the long hole. By loosening the adjusting nut 8, the screw rod 7 of the sealing plate 6 can slide along the long hole of the first inclined plate 401, and then tightening the adjusting nut 8 can limit the sliding of the sealing plate 6.
[0029] As a preferred implementation, Figure 3 As shown, the first inclined plate 401, the second inclined plate 402 and the tops of the side plates on both sides are provided with connecting plates 403, and the connecting plates 403 are connected to the feed box 2 by bolts. Preferably, the fixing plate 9 includes a connecting portion connected to the connecting plate 403 and a pressing portion for pressing the sealing plate 6.
[0030] As a preferred embodiment, an observation hole is provided on the discharge hopper 4 and a blocking plate 10 for closing the observation hole is detachably connected thereto.
[0031] As a preferred embodiment, the observation hole is provided on the second inclined plate 402 , and the blocking plate 10 can be fixed to the second inclined plate 402 of the discharge hopper 4 by bolts.
[0032] As a preferred implementation, Figure 4 As shown, a mechanical micro switch 11 is installed in the feed box 2, and the mechanical micro switch 11 is connected to a controller that controls the opening and closing of the feed pipe 3. Figure 6As shown, the feed 12 in the feed pipe 3 enters the transfer hopper 1. If the conveying capacity of the feed pipe 3 is greater than that of the discharge pipe 5, the feed in the transfer hopper 1 will increase, as shown in Figure a; when the feed is so much that it touches the mechanical micro switch 11, the mechanical micro switch 11 will transmit a signal to the controller to stop the feed pipe 3 from running, while the discharge pipe 5 continues to run, as shown in Figure b; as the discharge pipe 5 runs, the feed in the transfer hopper 1 will decrease, as shown in Figure c; until the mechanical micro switch 11 rebounds back to its original position due to the lack of feed extrusion, the feed pipe 3 continues to run, and the feed in the transfer hopper 1 will increase, as shown in Figure d, and then it will enter periodically, as shown in Figures a, b, c, d…
[0033] Preferably, the mechanical micro switch 11 is installed in the feed box 2 and is located at a position where the feed stacking height reaches 60% to 70% of its maximum stacking volume. When the feed stacking height reaches this height, the micro switch 11 will be triggered to automatically stop the operation of the feed pipe 3, while allowing the discharge pipe 5 to continue to operate, so as to reduce the amount of feed in the transfer hopper 1, prevent overfilling and reduce the load and failure rate of the feed line operation. The setting height of the mechanical micro switch 11 can ensure that after the mechanical micro switch 11 is triggered, the discharge pipe 5 can continue to transport normally.
[0034] In the transfer hopper 1 of the utility model, the feed of the feed pipe 3 flows into the transfer hopper 1 through the discharge port, and then flows into the discharge pipe 5 through the outlet of the discharge hopper 4. The adjusting nut 8 is loosened to make the sealing plate 6 slide along the first inclined plate 401, and then the adjusting nut 8 is tightened to limit the sliding of the sealing plate 6, thereby changing the sliding position of the sealing plate 6 to change the size of the outlet of the discharge hopper 4, thereby controlling the proportion of the feed of the feed pipe 3 entering the discharge pipe 5, so that the discharge pipe 5 can be in an optimal operating state, with a small operating load and a low failure rate. When there is too much accumulated feed stored in the transfer hopper 1, the mechanical micro switch 11 will be triggered to control the feed pipe 3 to stop, while the discharge pipe 5 continues to operate, and the accumulated feed in the transfer hopper 1 will be reduced. When there is too little feed stored in the transfer hopper 1, the mechanical micro switch 11 will stop working, and the feed pipe 3 will start to continue to transport feed to the transfer hopper 1. The mechanical micro switch 11 stops the feed pipe 3 in time to prevent the discharge pipe 5 from carrying away the accumulated feed in the transfer hopper 1 too late, thereby alleviating the feed blockage obstacle of the discharge pipe 5 and the feed pipe 3 and reducing the failure rate of the feed line operation.
