[0022] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0023] See Figures 1 to 3This utility model provides a height limiting structure for a material tower, installed on a material tower 1. The material tower 1 has a connected inlet 2 and an inner cavity 3. The height limiting structure includes:

[0024] A first retaining ring 4 is disposed in the inner cavity 3 and located below the feed inlet 2. The first retaining ring 4 has an axial direction and a radial direction, and a guide port 5 for connecting the feed inlet 2 and the inner cavity 3 is provided along its axial direction.

[0025] Multiple baffles 6 are spaced apart on the first baffle ring 4 along the inner circumferential surface of the material guide port 5, and each baffle 6 extends in the radial direction to divide the material guide port 5 into multiple material guide channels.

[0026] The baffle 6 is provided with a first inclined surface 61 and a second inclined surface 62 facing away from each other. The high end of the first inclined surface 61 and the high end of the second inclined surface 62 are connected and face the feed inlet 2. The low ends of both extend away from the feed inlet 2, so that the material guiding channel formed between two adjacent baffles 6 is gradually narrowed.

[0027] The first retaining ring 4 is rotatably equipped with a scraper 7, which is used to pass through each of the material guide channels one by one.

[0028] In this embodiment, a first baffle ring 4 is provided in the inner cavity 3 of the feed tower 1. The first baffle ring 4 is located at the high material level of the feed tower 1 and below the feed inlet 2. The first baffle ring 4 has a guide port 5 that connects to the inner cavity 3 of the feed inlet 2. The guide port 5 is divided by multiple baffles 6 to form multiple guide channels. The baffles 6 are designed with a first inclined surface 61 and a second inclined surface 62 arranged in opposite directions, so that the guide channels between adjacent baffles 6 are gradually narrowed. This facilitates the guidance of feed to be dispersed into multiple guide channels when it falls from the feed inlet 2, and to slide naturally along the first inclined surface 61 or the second inclined surface 62. This avoids the feed from accumulating at one point. The feed is evenly dispersed when it enters the inner cavity 3, effectively preventing local areas from reaching the high material level too early and reducing the occurrence of false alarms. In addition, a scraper 7 (motor-driven, not shown) is rotatably provided on the first baffle ring 4. The scraper 7 can pass through each feed channel one by one. During the feeding process of the feed tower 1, the rotation of the scraper 7 can promptly remove feed that may be blocked in the feed channel, keep the channel unobstructed, and ensure the continuous flow of feed. If a certain area overflows to the first baffle ring 4, the scraper 7 can also hang the feed into the low feed area, further avoiding the problem of excessive local accumulation of feed. This ensures accurate monitoring of the material height in the feed tower 1. The monitoring sensor (an infrared transmitter and receiver (through-beam type) installed opposite each other at the height limit position on the hopper wall, or installed on the same side (reflective type)) is set above the first baffle ring 4. When the feed tower 1 is full, the scraper 7 will scrape the feed that overflows to the upper surface of the first baffle ring 4 and can trigger a buzzer connected to the monitoring sensor to issue a high material level full load alarm.

[0029] The junction between the first inclined surface 61 and the second inclined surface 62 is configured as a first tip.

[0030] In this embodiment, when the feed falls from the feed inlet 2, it will first hit the top of the baffle 6. If the top is flat or round, the feed may form a small retention area on the top. However, the first tip prevents the falling feed from having a flat surface to stay on. When the feed hits the first tip, it will effectively slide down to both sides along the first inclined surface 61 and the second inclined surface 62 and directly enter the adjacent feed channel, reducing the accumulation on the top of the baffle 6.

[0031] The first retaining ring 4 is coaxially provided with a second retaining ring 8, which is used to divide each of the material guiding channels into an inner material guiding channel and an outer material guiding channel from the inside to the outside.

[0032] In this embodiment, after adding the second baffle ring 8, the feed can flow to the first baffle ring 4 or the second baffle ring 8 and be separated by the first baffle ring 4 or the second baffle ring 8. This makes the material that was originally going to fall into a certain area of ​​the inner cavity 3 finely divided into two finer streams, which fall into different radial positions in the inner cavity 3 of the feed tower 1 through the inner guide channel and the outer guide channel, respectively. The secondary diversion makes the feed more widely and evenly distributed on the radial cross section of the feed tower 1, avoiding the formation of a single conical pile of material directly below the feed inlet 2.

[0033] The second retaining ring 8 is provided with a third inclined surface 81 and a fourth inclined surface 82 facing away from each other. The high end of the third inclined surface 81 is connected to the high end of the fourth inclined surface 82, and the low ends of the two extend inward and outward in the direction of the feed inlet 5, respectively.

[0034] In this embodiment, the second baffle ring 8 is provided with a third inclined surface 81 and a fourth inclined surface 82 arranged opposite to each other. The feed falling from the feed inlet 2 to the second baffle ring 8 will hit the top of the second baffle ring 8 head-on and slide down the third inclined surface 81 into the inward guide channel. Another part slides down the fourth inclined surface 82 into the outward guide channel. The feed is better scattered into different radial positions in the inner cavity 3 of the feed tower 1, so that the material can always be guided and dispersed by the inclined surface from the first baffle ring 4 or the second baffle ring 8, optimizing the flow path of the material and making the final distribution of feed in the feed tower 1 more uniform.

[0035] The connection between the third inclined surface 81 and the fourth inclined surface 82 is configured as a second tip, and the second tip faces the feed inlet 2.

[0036] In this embodiment, the top of the second baffle ring 8 has a second tip, which minimizes the contact area with the feed and allows the material to be diverted along the third inclined surface 81 and the fourth inclined surface 82, respectively entering the inner guide channel and the outer guide channel.

[0037] The scraper 7 is provided with a notch 71, which is rotatably engaged with the second tip.

[0038] In this embodiment, a notch 71 is provided on the scraper 7. The scraper 7 rotates on the second retaining ring 8 through the notch 71, ensuring that the scraper 7 can rotate smoothly and continuously, avoiding direct impact between the scraper 7 and the second tip. This not only protects the scraper 7 itself, but also prevents the second tip from being deformed or worn due to repeated impacts.

[0039] The scraper 7 is provided with a fifth inclined surface 72 and a sixth inclined surface 73 facing away from each other. The high end of the fifth inclined surface 72 is connected to the high end of the sixth inclined surface 73 and faces the feed inlet 2.

[0040] In this embodiment, the scraper 7 is provided with a fifth inclined surface 72 and a sixth inclined surface 73 arranged in opposite directions. When the scraper 7 rotates, the fifth inclined surface 72 or the sixth inclined surface 73 comes into contact with the accumulated material, which can decompose the forward thrust into a downward component force, making it easier to scrape the material into the guide channel, thereby reducing the scraping resistance. In addition, the fifth inclined surface 72 and the sixth inclined surface 73 also have the function of diverting the feed falling from the feed inlet 2, instead of accumulating on the scraper 7.

[0041] The connection between the fifth inclined surface 72 and the sixth inclined surface 73 is configured as a third tip.

[0042] In this embodiment, the task of the scraper 7 is to clean the residual material located on the first retaining ring 4 or the second retaining ring 8. The design of the third tip minimizes the contact area between the top of the scraper 7 and the material, preventing the material from staying on it. Any material falling on the scraper 7 will quickly slide from the third tip to the fifth inclined surface 72 or the sixth inclined surface 73 due to its own weight and the centrifugal force of rotation, and will eventually be thrown into the inner guide channel or the outer guide channel, ensuring that the scraper 7 can always keep itself clean and reducing the rotational resistance of the scraper 7.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
