Description

Technical Field

[0001] This utility model relates to the field of negative pressure equipment, and specifically to a suction head structure. Background Technology

[0002] Currently, existing suction head structures mainly include straight-tube suction heads and suction heads equipped with scraper rotating discs. During the suction process, the suction head descends at a constant speed, contacts the material, and then uses a negative pressure device connected to the suction head to suck up the material. However, when too much material is sucked up and the descent speed is too fast, the feed inlet of the suction head will be buried by the material. After the suction head is buried to a certain depth, the feed inlet will be completely blocked.

[0003] Especially for high-density powders, the buried feed inlet cannot connect to the outside air, thus failing to form a passage. This can cause a short circuit in the airflow, easily leading to the burnout of the blower motor. Moreover, especially for scraper-type suction heads with rotating discs, the torque required for scraping increases after burial to a certain depth, placing a greater load on the power components of the rotating disc. This can prevent the device from functioning properly and can easily damage the equipment.

[0004] Therefore, how to propose a suction head structure has become a technical problem that urgently needs to be solved in the industry. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the shortcomings of the existing technology, this utility model provides a suction head structure that can easily suck up materials.

[0006] Technical solution: A suction head structure, comprising:

[0007] hollow tube body;

[0008] A cavity is provided at the bottom of the tube body, and a feed inlet is provided at the bottom of the cavity body. The outer surface of the cavity body is divided into a first inclined surface and a second inclined surface arranged vertically. The first inclined surface is configured to slope downwards and outwards from the tube body along the axis of the tube body. The second inclined surface has the opposite slope direction to the first inclined surface.

[0009] A plurality of breathing tubes are arranged around the feed inlet, the top end of the breathing tubes being configured to extend vertically upward beyond the height of the cavity, and the bottom end of the breathing tubes being configured to be located near the edge of the feed inlet and radially toward the feed inlet.

[0010] Furthermore, a number of scraper blades are provided around the feed inlet, and the scraper blades are centrally symmetrically distributed around the axis of the feed inlet, with each of the breathing tubes disposed between the scraper blades.

[0011] Furthermore, the first inclined plane and the second inclined plane have the same inclination angle and opposite inclination directions.

[0012] Furthermore, the tip of the breathing tube is configured to extend vertically upward beyond the height of the cavity.

[0013] Furthermore, the bottom of the breathing tube is positioned close to the second inclined surface.

[0014] Beneficial effects: This utility model's suction head structure, by setting a first inclined plane and a second inclined plane with opposite directions, guides the material to fall and prevents it from accumulating. The second inclined plane, after inserting the material, fits snugly against the material's stacked state, thus providing stability and preventing equipment shaking. Furthermore, it can still suction material normally even when the inlet is buried. The breather pipe provides an air intake channel when the inlet is nearly blocked, ensuring the entire suction airway operates normally during the suction process and preventing short circuits. Moreover, the structure is simple, easy to manufacture, low-cost, and easy to promote. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0018] It should be noted that the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope of this utility model.

[0019] See Figure 1-2An embodiment of the suction head structure of this utility model is shown, comprising: a tube 1, a cavity 2, and a breathing tube 4. The tube 1 is hollow and is used to connect to an external negative pressure device. The tube 1 is also connected to an external power device 6 to drive the tube 1 to rotate. The cavity 2 is located at the bottom of the tube 1, and the bottom of the cavity 2 is provided with a feed inlet 3. The outer surface of the cavity 2 is divided into a first inclined surface 21 and a second inclined surface 22 arranged vertically. The first inclined surface 21 is configured to slope downward along the axis of the tube 1 and outward from the tube 1. The second inclined surface 22 has the opposite slope direction to the first inclined surface 21.

[0020] Multiple breathing tubes 4 are configured to surround the feed inlet 3. The top end of the breathing tube 4 is configured to extend vertically upward beyond the height of the cavity 2, and the bottom end of the breathing tube 4 is configured to be located near the edge of the feed inlet 3 and radially toward the feed inlet 3.

[0021] In operation, the suction head descends while simultaneously connecting to the negative pressure component to draw in material. Material at the inlet 3 is first sucked away, and then, through the rotation of the scraper 5, the material within the scraper 5's range is scraped into the inlet 3. Furthermore, the device utilizes a first inclined plane 21 and a second inclined plane 22 with opposite directions. The first inclined plane 21 guides the material's fall, preventing accumulation, while the second inclined plane 22, after inserting into the material, conforms to the material's stacked state, providing stability and preventing equipment shaking. Moreover, it can still draw in material even when the inlet 3 is buried. The breather pipe 4 provides an air intake channel when the inlet 3 is nearly blocked, ensuring the entire suction airway operates normally without short-circuiting. The structure is simple, easy to manufacture, low-cost, and easy to promote.

[0022] In some preferred embodiments, a plurality of scraper blades 5 are provided around the feed inlet 3. The scraper blades 5 are centrally symmetrically distributed around the axis of the feed inlet 3, and each of the breathing tubes 4 is disposed between the scraper blades 5. When the tube body 1 is rotated by the external power device 6, the scraper blades 5 are also rotated, thereby activating the material, preventing the material from caking, and thus facilitating material suction.

[0023] In some preferred embodiments, the first inclined surface 21 and the second inclined surface 22 have the same inclination angle and opposite inclination directions. In other embodiments, while ensuring that the inclination directions of the first inclined surface 21 and the second inclined surface 22 are opposite, the inclination angles of the first inclined surface 21 and the second inclined surface 22 can be set to be different. Such structural changes still fall within the protection scope of this utility model.

[0024] In some preferred embodiments, the tip of the breathing tube 4 is configured to extend vertically upwards beyond the height of the cavity 2. In some preferred embodiments, the tip of the breathing tube 4 may also be configured to extend obliquely outwards from the cavity 2; such structural variations still fall within the protection scope of this utility model.

[0025] In some preferred embodiments, the bottom of the breathing tube 4 is positioned close to the second inclined surface 22. In this way, the bottom of the breathing tube 4 can also scrape and revitalize the material during the rotation of the suction head structure.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
