Those skilled in the art can make similar deformations without violating the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0020] The present invention provides a mobile adjustable concrete pouring chute (such as Figure 1As shown), it includes a hollow trapezoidal chute 1, a mobile trolley 2, and an azimuth adjustment mechanism. The hollow trapezoidal chute 1 is used to receive the concrete flowing out of the chute of the concrete mixer truck. When the hollow trapezoidal chute 1 maintains a certain inclination angle, the concrete flowing into the hollow trapezoidal chute 1 directly flows out under its guidance. In practical applications, the hollow trapezoidal chute 1 can be made of stainless steel. The hollow trapezoidal chute 1 is arranged on the mobile trolley 2. The flexible mobility of the mobile trolley 2 is utilized to realize the flexible movement of the hollow trapezoidal chute 1, thereby facilitating the reuse of the hollow trapezoidal chute 1 and reducing the cost of concrete pouring construction. The hollow trapezoidal chute 1 can be adjusted up and down, tilted, and adjusted relative to the mobile trolley 2. The inclined angle adjustment and positioning of the hollow trapezoidal chute 1 can be adjusted up and down relative to the mobile trolley 2, which makes it easy for the hollow trapezoidal chute 1 to be suitable for receiving and conveying concrete with different height differences. The inclined angle of the hollow trapezoidal chute 1 can be adjusted relative to the mobile trolley 2, which makes it easy for the hollow trapezoidal chute 1 to realize accurate conveying of concrete. The hollow trapezoidal chute 1 can remain motionless on the mobile trolley 2, which can ensure the stable conveying of concrete by the hollow trapezoidal chute 1. An inlet 11 is provided on the upper side wall of the hollow trapezoidal chute 1, and a flexible discharge pipe 4 is provided on the upper bottom side wall of the hollow trapezoidal chute 1. The flexible discharge pipe 4 is connected to the interior of the hollow trapezoidal chute 1, and the chute out of the concrete mixer truck passes through The feed inlet 11 enters into the hollow trapezoidal chute 1, and then enters into the flexible discharge pipe 4, and finally flows out from the outlet of the flexible discharge pipe 4 to the designated pouring position. When the hollow trapezoidal chute 1 realizes the receiving and diversion of concrete, in order to prevent the concrete from overflowing, an overflow prevention cover 12 is provided at the front of the feed inlet of the hollow trapezoidal chute 1. In the present specific embodiment, the flexible discharge pipe 4 can be an existing corrugated pipe, and a supporting assembly is provided at the bottom of the hollow trapezoidal chute 1, and the supporting assembly is used to auxiliary support the lower part of the flexible discharge pipe 4. When operating in a high temperature environment in summer, the flexible discharge pipe 4 becomes very soft, which results in its own insufficient supporting strength, and then it is easy to deform when it transports concrete. , which will affect the precise delivery of concrete to a certain extent, and the support assembly can be used to support the lower part of the flexible discharge pipe 4, thereby ensuring its precise delivery of concrete; the orientation adjustment mechanism is used to assist manual operation in moving and adjusting the casting orientation of the discharge port of the flexible discharge pipe 4. During the continuous discharge process of the flexible discharge pipe 4, the orientation adjustment mechanism can be used to manually adjust the casting position of the discharge port of the flexible discharge pipe 4, thereby achieving uniform distribution of concrete at the casting position, which can reduce the subsequent workload of leveling the concrete. At the same time, the flexibility of the flexible discharge pipe 4 and the movable ability of its discharge port can be used to expand the casting range of the concrete to a certain extent, thereby facilitating the improvement of the casting efficiency of the concrete.

[0021] Based on the above embodiments, the specific implementation of the mobile trolley 2 is as follows: The mobile trolley 2 includes a square fixed frame 21. At the bottom of the square fixed frame 21, four walking wheels 211 are provided. By the support of the walking wheels 211, the movement of the mobile trolley 2 is realized. In this specific embodiment, the walking wheels 211 can be universal wheels with a braking function. The square fixed frame 21 includes four support vertical pipes 212. The four support vertical pipes 212 are all vertically arranged and are fixedly connected by a plurality of connecting rods. On the left and right sides of the square fixed frame 21, a ∩-shaped frame 22 is provided. The two vertical rods 221 of the ∩-shaped frame 22 are correspondingly inserted into the corresponding two support vertical pipes 212. The two vertical rods of the ∩-shaped frame are fixedly connected by a plurality of connecting rods. The ∩-shaped frame 22 can be adjusted up and down and positioned relative to the square fixed frame 21. Specifically, a positioning hole 2121 is provided at the upper part of each support vertical pipe 212. A plurality of adjusting holes 2211 adapted to the positioning holes 2121 are provided on the vertical rods 221 of each ∩-shaped frame 22. The plurality of adjusting holes 2211 are equally spaced along the height direction of the vertical rod 221. A pin shaft is inserted into the positioning hole 2121 and the corresponding adjusting hole 2211 to realize the relative positioning of the vertical rod 221 and the support vertical pipe 212, and then the support and fixation of the ∩-shaped frame 22 are realized. When it is necessary to adjust the height of the ∩-shaped frame 22, first pull out the pin shaft from the adjusting hole 2211, then adjust the height of the ∩-shaped frame 22. After adjusting its height, insert the pin shaft into the positioning hole 2121 and the corresponding adjusting hole 2211 again, so as to complete the height adjustment of the ∩-shaped frame 22. The two sides at the rear of the middle of the hollow trapezoidal chute 1 are hinged to the corresponding ∩-shaped frames 22. Specifically, a support rotating shaft 13 is fixedly provided on both sides at the rear of the middle of the hollow trapezoidal chute 1. The support rotating shaft 13 is rotatably arranged on the corresponding ∩-shaped frame 22. By the rotation of the support rotating shaft 13, the rotation of the hollow trapezoidal chute 1 is realized. In the actual application process, relying on its own gravity and the gravity of the flexible discharge pipe 4, the front part of the hollow trapezoidal chute 1 will automatically swing downward without external force.

[0022] On the basis of the above embodiments, to facilitate the implementation of the tilting and swinging positioning of the hollow trapezoidal chute 1, here, an adjustment positioning plate 222 is fixedly arranged on the upper part of the front side of each of the ∩-shaped frames 2. A number of jacks 2221 are arranged on the adjustment positioning plate 222 and are equally spaced along the circumferential direction of the rotation axis of the hollow trapezoidal chute 1. A plug rod 223 is inserted into the corresponding jack 2221. After the bottom of the hollow trapezoidal chute 1 contacts the upper part of the plug rod 223, the plug rod 223 realizes the rotational limit of the hollow trapezoidal chute 1. When it is necessary to adjust the tilting angle of the hollow trapezoidal chute 1 again, first pull out the plug rod 223 from the jack 2221, and then rotate the hollow trapezoidal chute 1. When the hollow trapezoidal chute 1 rotates to a suitable angle, keep the hollow trapezoidal chute 1 stationary, insert the plug rod 223 into the corresponding jack 2221. When selecting the jack 2221, it is necessary to ensure that the jack 2221 is the one closest to the bottom of the hollow trapezoidal chute 1. After the insertion of the plug rod 223 is completed, release the hollow trapezoidal chute 1, and its front bottom will automatically fall onto the plug rod 223, thereby using the plug rod 223 to block its rotation and realizing the adjustment and fixation of its tilting angle.

[0023] Based on the above embodiments, the specific implementation of the support assembly is as follows: The support assembly includes a rotating sleeve 51, a support rod 52, and an arc-shaped support plate 53. The rotating sleeve 51 is rotatably arranged on the front side of the bottom of the hollow trapezoidal chute 1. Specifically, an inverted T-shaped ear is fixedly arranged on the front side of the bottom of the hollow trapezoidal chute 1, and an inverted T-shaped through hole corresponding to the inverted T-shaped ear is arranged on the upper side wall of the rotating sleeve 51. The inverted T-shaped ear is sleeved in the inverted T-shaped through hole, and the rotating sleeve 51 can rotate freely relative to the inverted T-shaped ear. The support rod 52 is sleeved in the rotating sleeve 51 and the support rod 52 can move back and forth relative to the rotating sleeve 51. The arc-shaped support plate 53 is fixedly arranged at the front part of the support rod 52, and the arc-shaped support plate 53 has an upward opening. In practical applications, the arc-shaped support plate 53 is clamped at the lower part of the flexible discharge pipe 4. The position of the arc-shaped support plate 53 can be adjusted through the support rod 52, and then the flexible support of the arc-shaped support plate 53 for the flexible discharge pipe 4 can be realized. When the flexible discharge pipe 4 rotates to a certain extent, by using the flexible rotation of the rotating sleeve 4, the arc-shaped support plate 53 can rotate synchronously with the flexible discharge pipe 4, ensuring the stable support of the arc-shaped support plate 53 for the flexible discharge pipe 4. A pressing bolt 54 for positioning the support rod 52 is arranged on the rotating sleeve 51. When the support rod 52 is fixed by the pressing bolt 54, the support stability of the support rod 52 is improved. In practical applications, to prevent the arc-shaped support plate 53 from rotating freely, a first positioning plane is arranged on the inner side wall of the rotating sleeve 51, and a second positioning plane 521 corresponding to the first positioning plane is arranged on the side wall of the support rod 52. The rotation limit of the support rod 52 is realized by the fitting of the first positioning plane and the second positioning plane 521, and the pressing bolt 54 can press on the second positioning plane 521.

[0024] Based on the above embodiments, the specific implementation of the azimuth adjustment mechanism is as follows: The azimuth adjustment mechanism includes a clamp 31 and a pull rod. The clamp 31 is clamped and fixed on the outer side of the discharge port of the flexible discharge pipe 4. The clamp 31 is a mature technical product in the existing market, so the detailed structure of the clamp 31 will not be described in detail here. A pull ring 32 is fixedly arranged on the outer side wall of the clamp 31. A hook is arranged at one end of the pull rod, and the hook can be hung on the pull ring 32. During the concrete pouring process, when it is necessary to change the outlet position of the flexible discharge pipe 4, at this time, the staff holds the pull rod and hangs the hook of the pull rod on the pull ring 32. After hanging, by pulling the pull ring 32 through the pull rod, the change of the outlet position of the flexible discharge pipe 4 is realized, and thus the change of the pouring position is realized.
