If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0021] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0022] In the description of the present application, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0023] Reference Figures 1 to 4 The embodiment of the present application provides a low-noise concrete mixer that is easy to move, including: Rack 100; A mixing drum 300 , the mixing drum 300 is vertically arranged on the frame 100 ; A stirring mechanism 400, wherein the stirring mechanism 400 is rotatably disposed in the stirring drum 300, and the stirring mechanism 400 is coaxially distributed with the stirring drum 300; A walking mechanism, which is arranged at the bottom of the frame 100 and is used to support the frame 100 for walking. A first walking wheel set 101 is arranged on one side of the walking mechanism, and a second walking wheel set 102 and a supporting foot 103 are arranged on the other side of the walking mechanism. The second walking wheel set 102 can be raised and lowered; Among them, the second walking wheel group 102 has a first state and a second state during the lifting and adjusting process. When the second walking wheel group 102 is in the first state, the bottom of the second walking wheel group 102 is higher than the supporting foot 103. When the second walking wheel group 102 is in the second state, the bottom of the second walking wheel group 102 protrudes downward relative to the supporting foot 103; and a buffer portion is provided at the bottom of the supporting foot 103.

[0024] It is understandable that the low-noise concrete mixer that is easy to move in this application is provided with a first walking wheel group 101 and a second walking wheel group 102 at the bottom. When it needs to be moved, the second walking wheel group 102 is adjusted downward to the second state so that the support foot 103 is separated from the ground, and the first walking wheel group 101 can be coordinated for movement and adjustment, so as to facilitate the work and quickly move the mixer to the set site. After moving into place, the second walking wheel group 102 is adjusted upward to the first state so that the second walking wheel group 102 is separated from the ground and the support foot 103 is supported on the ground, so as to fix the mixer. At the same time, when the mixer is working, the buffer part can be used for shock absorption. When there is a small gap between the support foot 103 and the ground, or when the ground is slightly settled under vibration and causes a gap, the support foot 103 can be prevented from colliding with the ground to generate noise. Therefore, the low-noise concrete mixer that is easy to move in this application can not only solve the problem of difficult handling, but also alleviate the problem of running noise.

[0025] Furthermore, in the working state, the entire device generally remains horizontal, so when the support legs 103 cooperate with the first running wheel set 101 to support the frame 100, the entire device remains horizontal. Furthermore, when the second running wheel set 102 is adjusted downward to the second state, the second running wheel set 102 will lift one side of the frame 100, so that the entire device is tilted toward the first running wheel set 101 at a certain angle. When transporting, the tilt angle can be effectively used to change the center of gravity of the mixer, thereby improving the convenience of transportation.

[0026] In some embodiments of the present application, the walking mechanism is provided with a manual drive component, which is used to control the lifting and lowering adjustment of the second walking wheel set 102. Since the on-site environment of concrete mixing is generally poor, electric adjustment requires power connection, circuit safety, additional control, etc., and the structure is relatively complex. This embodiment uses manual adjustment to simplify the structural composition and has high reliability.

[0027] Reference Figures 1 to 3 Specifically, the manual drive assembly can be set as a hand jack 200. The structure of the hand jack 200 is mature and reliable, and the cost is controllable. While realizing the lifting function design of the second running wheel group 102, a substantial increase in cost can be avoided.

[0028] Further, the second traveling wheel set 102 includes a lifting frame and a roller arranged at the bottom of the lifting frame, and the lifting frame is provided with two vertical beams and a horizontal beam connected between the vertical beams, wherein the vertical beam is vertically slidably penetrated on the frame 100. The hand jack 200 is arranged between the upper end of the horizontal beam and the frame 100, and when extended by hand, the horizontal beam is driven to move downward, thereby controlling the entire lifting frame to move downward.

[0029] It is understandable that by using the hand jack 200 , the self-locking function of the hand jack 200 can be utilized to ensure the load-bearing stability of the second running wheel set 102 .

[0030] In some embodiments of the present application, the first running wheel set 101 and the second running wheel set 102 are configured as universal wheels to facilitate direction adjustment and steering adjustment.

[0031] Reference Figure 4 In some embodiments of the present application, the support foot 103 is provided with a plurality of buffers, and each buffer is arranged on the support foot 103 in a manner that can be raised and lowered. Since the site of the construction site may be uneven, this embodiment provides a plurality of buffers, and each buffer can be raised and lowered to adjust the site flatness, thereby improving applicability. When necessary, the buffer can also be adjusted to adapt to slight settlement of the ground to ensure the overall level of the mixer.

[0032] In some embodiments of the present application, a plurality of screw sleeves are arranged circumferentially on the support foot 103, and the buffer part is screwed into the screw sleeve. When adjustment is required, it is only necessary to control the rotation of the buffer part, and the lifting and lowering adjustment can be performed by cooperating with the thread of the screw sleeve. It is understandable that the screw sleeve is fixedly arranged on the support foot 103, and can be fixed by welding or other fixing methods.

[0033] Reference Figure 4 In some embodiments of the present application, the buffer portion includes: A mounting column 1031, wherein a mounting cavity 1032 with a bottom opening is arranged at the center of the mounting column 1031, a boss is arranged radially at the lower end of the mounting column 1031, and an external thread is arranged above the boss on the mounting column 1031, and the external thread matches the thread sleeve; A rubber head 1033, the rubber head 1033 is disposed in the mounting cavity 1032, and the bottom of the rubber head 1033 protrudes downward relative to the mounting column 1031; A spring washer is sleeved on the mounting column 1031 and abuts between the boss and the supporting foot 103 .

[0034] With the structural setting of this embodiment, the rubber head 1033 is limited and fixed by the mounting cavity 1032, and the bottom is kept protruding from the lower end of the mounting column 1031. Further, the lower end of the rubber head 1033 is expanded to match the outer diameter of the boss, thereby covering the lower end of the mounting column 1031. When adjusting, the mounting column 1031 can be rotated to move upward or downward relative to the screw sleeve, thereby changing the height of the rubber head 1033. The spring washer can prevent the mounting column 1031 from loosening due to vibration, which helps to improve the stability of the height position after adjustment.

[0035] Reference Figure 4 Furthermore, the buffer part further includes an adjusting nut 1034, which is threadedly mounted on the mounting column 1031, and the adjusting nut 1034 is located above the threaded sleeve. In this embodiment, by providing the adjusting nut 1034, it is convenient to assist in controlling the lifting and lowering of the mounting column 1031 by rotating the adjusting nut 1034.

[0036] Furthermore, the outer contour of the boss is set to a regular hexagon, so that the boss can be used to control the installation column 1031 to rotate and achieve lifting and lowering adjustment.

[0037] Reference Figure 3 In some embodiments of the present application, the upper opening of the mixing drum 300 is provided to form a feed port 301 for feeding, adding water, etc. A discharge port 302 is provided at one side of the bottom of the mixing drum 300. In addition, the portable low-noise concrete mixer further includes an opening and closing mechanism, which is used to control the opening and closing of the discharge port 302.

[0038] Reference Figure 3 ,Specifically, the opening and closing mechanism includes: The baffle 500 is rotatably disposed at the bottom of the mixing drum 300, and the baffle 500 can cover or open the discharge port 302 during the rotation process; A lever 501, the lever 501 is fixedly connected to the baffle 500, the lever 501 is provided with a control rod 502, the control rod 502 is vertically arranged, and during the rotation of the baffle 500, the control rod 502 is always located outside the mixing drum 300; The abutment portion 503 is fixedly disposed at the bottom of the mixing drum 300; When the baffle 500 is rotated to fully open the discharge port 302, the upper end surface of the baffle 500 abuts against the abutment portion 503, or, when the baffle 500 is rotated to fully open the discharge port 302 and continues to rotate at a set angle in the same direction, the upper end surface of the baffle 500 abuts against the abutment portion 503.

[0039] With the structural arrangement of this embodiment, the baffle 500 can be driven to rotate by the lever 501 to control the opening and closing of the discharge port 302. The control lever 502 on the lever 501 is always located outside the mixing drum 300, which is convenient for workers to operate and avoids the need to reach under the mixing drum 300 to grope, making it easy to use.

[0040] In addition, an abutment portion 503 is provided at the bottom of the mixing drum 300. When the baffle 500 fully opens the discharge port 302, it rotates until the upper end surface abuts against the abutment portion 503, which can improve the stability of the baffle 500 and alleviate the vibration and noise generated by the operation of the mixing mechanism 400.

[0041] In some embodiments of the present application, the upper end height of the control rod 502 is higher than the bottom height of the mixing drum 300, and an anti-slip sleeve is provided on the control rod 502. When the baffle 500 abuts against the abutment portion 503, the control rod 502 fits against the outer wall of the mixing drum 300. With the structural setting of this embodiment, when the baffle 500 fully opens the discharge port 302, it abuts against the abutment portion 503, and the control rod 502 also abuts against the outer side of the mixing drum 300, which can effectively reduce its own degree of freedom and alleviate the situation where vibration generates noise.

[0042] Furthermore, the abutting portion 503 and the anti-slip sleeve are made of polyurethane or rubber to achieve shock absorption.

[0043] Reference Figures 1 to 3 In some embodiments of the present application, the stirring mechanism 400 includes: A rotating shaft, the rotating shaft is rotatably disposed at the center of the mixing drum 300; A stirring blade, the stirring blade is located in the stirring drum 300, and the stirring blade includes a central mounting seat coaxially fixedly connected to the rotating shaft, and a plurality of blade units distributed around the central mounting seat, and the blade unit includes a spiral blade 401 and a reinforcing plate 402, one end of the reinforcing plate 402 is connected to the end of the spiral blade 401, and the other end is connected to the upper end of the central mounting seat; The driving motor is disposed on the frame 100 and is transmission-connected to the lower end of the rotating shaft.

[0044] With the structural arrangement of this embodiment, the stirring blade can improve the stability of the spiral blade 401 by providing the reinforcing plate 402, thereby alleviating the situation where the spiral blade 401 generates noise when vibrating. In addition, the reinforcing plate 402 can also improve the mixing efficiency.

[0045] In summary, the mobile low-noise concrete mixer in the present application can be transported by setting up a walking mechanism, and the operating noise can be reduced by the shock-absorbing support of the support legs 103 and the related designs of the baffle 500 and the mixing blades.

[0046] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
