[0001] This utility model relates to the field of construction equipment technology, specifically to a discharge port structure for a mixer. Background Technology

[0002] Mobile concrete mixers are widely used in construction projects due to their portability. Their discharge port integrates both feeding and discharging functions. To facilitate the preparation of cement mortar, water is added to the mixing chamber, and a water supply hose is usually connected to the discharge port.

[0003] However, current mobile concrete mixers have open discharge ports, which cause cement mortar to splash during mixing, affecting site hygiene. Furthermore, the lack of a fixed pipe structure at the discharge port means that simply inserting the water pipe end into the mixer can easily cause the pipe to detach from the discharge port under water pressure, affecting the continuity of water supply. In practice, during cement mortar preparation, additional personnel are often needed to manually inject water using the hose, which is quite inconvenient.

[0004] Therefore, based on feedback from on-site construction personnel, the applicant improved the discharge port structure of the traditional mobile concrete mixer and designed a new discharge port structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a discharge port structure for a mixer. This discharge port structure can effectively fix the pipe fittings and prevent them from coming off under water pressure.

The two sets of screws are respectively threaded with connecting seats, and the connecting seats are connected and fixed to the moving plates. The driving mechanism also includes a guide plate disposed on the other side of the dual-output shaft geared motor. The guide plate is provided with a guide groove, and the moving plate is provided with a guide bar that slides and adapts to the guide groove.

[0008] Preferably, the pipe socket includes a clamping seat and a clamping plate. The clamping seat is fixedly connected to the moving plate, and a groove for placing pipe fittings is provided on the clamping seat. The clamping plate is slidably connected to the clamping seat, and a first locking bolt for fixing the pipe fittings is threadedly connected to the clamping plate.

[0009] Preferably, a pair of sliding grooves are formed on the clamping seat, and protruding strips slidably adapted to the sliding grooves are provided on the folded edges on both sides of the clamping plate.

[0010] Preferably, the guiding seat has a "U" - shaped cross - section, and the height of the cross - section decreases successively from near to far from the pipe socket to guide the pipe fitting to be inclined and bent.

[0011] Preferably, the shielding cover is provided with a bent plate slidably connected to the moving plate.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] Example:

[0022] See Figures 1-4 In this embodiment, a discharge port structure for a mixer is disclosed. Specifically, it is used to introduce a water pipe 16 into the mixing chamber of a mobile concrete mixer and to reliably fix and shield it from splashing. Specifically, it includes an opening and closing component 11 for opening or closing the discharge port. The opening and closing component 11 includes two sets of moving plates 12. One set of moving plates 12 is provided with a pipe fitting 13 and a guide seat 14. The other set of moving plates 12 is slidably provided with a shield 15. The pipe fitting 13 is used to fix the pipe fitting 16, and the guide seat 14 is used to guide the head end of the pipe fitting 16 to tilt into the discharge port and extend into it.

[0023] Specifically, in this embodiment, when water needs to be introduced into the mixing chamber through the discharge port via the water pipe 16 for water injection, the two sets of moving plates 12 of the opening and closing mechanism are first separated to open the discharge port. Then, the head end of the water pipe 16 is placed into the pipe fitting 13 on one set of moving plates 12. The pipe fitting 13 firmly fixes the water pipe 16 to prevent it from coming out under water pressure. At the same time, the guide seat 14 guides the head end of the water pipe 16 to tilt and extend into the discharge port, ensuring that the water pipe 16 bends and delivers water into the mixing chamber. The water pipe 16 is fixed at the discharge port at a specific angle to achieve a continuous water supply. The shield 15 is slidably disposed on the other set of moving plates 12, so that the head of the water pipe 16 is located below the shield 15, effectively preventing water from spraying out of the discharge port. After water injection is completed, the two sets of moving plates 12 of the opening and closing mechanism are brought together to close the discharge port. This invention uses the opening and closing component 11 to shield the discharge port, preventing cement mortar from splashing out during the mixing process, maintaining site hygiene, reducing environmental pollution, and improving the cleanliness of the construction environment. The pipe connector 13 and guide seat 14 eliminate the need for additional personnel to hold the water pipe 16 for water injection, reducing labor costs and improving construction efficiency.

[0024] The opening and closing component 11 further includes a driving mechanism 21 for driving the two groups of moving plates 12 to move away from and close to each other. The driving mechanism 21 includes a double-output shaft reduction motor 22 fixed to the discharge port, and two groups of screw rods 23 respectively axially connected and fixed to both ends of the double-output shaft reduction motor 22. The two groups of screw rods 23 are respectively threadedly sleeved with connecting seats 24, and the connecting seats 24 are connected and fixed to the moving plates 12. Moreover, the driving mechanism 21 further includes a guide plate 25 arranged on the other side of the double-output shaft reduction motor 22. The guide plate 25 is provided with a guide groove 26, and the moving plate 12 is provided with a guide bar 27 slidably adapted to the guide groove 26, so that the moving plate 12 remains linearly parallel during the opening and closing movement, realizing the electric opening and closing operation of the discharge port and improving the convenience of use.

[0025] The pipe connection seat 13 described above includes a clamping seat 31 and a clamping plate. Refer to Figure 3 , the clamping seat 31 is connected and fixed to the moving plate 12, and the clamping seat 31 is provided with a groove 33 for placing the pipe fitting 16. The clamping plate is slidably connected to the clamping seat 31, and a first locking bolt 34 for fixing the pipe fitting 16 is threadedly connected to the clamping plate. Specifically, a pair of sliding grooves 35 are opened on the clamping seat 31, and protruding strips 36 slidably adapted to the sliding grooves 35 are provided on the folded edges on both sides of the clamping plate. During use, after the head end of the pipe fitting 16 is placed in the groove 33, the clamping plate is pushed to slide linearly above the pipe fitting 16, and the first locking bolt 34 is tightened to firmly clamp the pipe fitting 16. This structure can adapt to hoses with different outer diameters and can also make the pipe fitting 16 remain stable under the reverse pushing action of water pressure and avoid loosening.

[0026] The guide seat 14 described above adopts a "U" - shaped cross - section. Refer to Figure 4 , and the height of the cross - section decreases successively from near to far from the pipe connection seat 13, guiding the pipe fitting 16 to be inclined and bent, so that after the pipe fitting 16 is fixed, its end extends into the discharge port in an inclined manner, ensuring the stability of the water flow direction and still maintaining a stable angle even under the reverse impact of water pressure.

[0027] The shielding cover 15 is provided with a bending plate 41 slidably connected and adapted to the moving plate 12. The bending plate 41 is provided with two groups of through - slots 42 and a group of limiting slots 43. Corresponding to the moving plate 12, a T - shaped convex block 44 slidably adapted to the through - slots 42 is provided, and a second locking bolt 45 is threadedly connected. The second locking bolt 45 is slidably adapted to the limiting slot 43, and when it is tightened, the position of the bending plate 41 is fixed. In this embodiment, the shielding cover 15 can slide along the moving plate 12. To prevent the water flow of the water pipe 16 from splashing, it needs to be moved above the head end of the water pipe 16 and then fixed by tightening the second locking bolt 45.

[0028] Both the pipe fitting 13 and the guide seat 14 are detachably connected and fixed to the moving plate 12 by threaded fasteners 46. The detachable design facilitates the replacement or maintenance of the pipe fitting 13 and the guide seat 14 when needed, improving the ease of equipment maintenance.

[0029] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
