[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figure 1-Figure 5A raw material proportioning device for concrete comprises a mixing body 1, two conveying pipes 2 installed on one side of the mixing body 1 and a conveying box 3 installed at the other end of the two conveying pipes 2, the conveying box 3 is fixedly connected to a charging box 4 on the side away from the mixing body 1, and two shaking cavities 401 are arranged on the upper surface of the charging box 4, and two feeding ports 301 are penetrated and arranged on the side of the conveying box 3 close to the charging box 4, and the two feeding ports 301 are respectively connected to the two shaking cavities 401 and the two conveying pipes 2, and the inner walls of the two shaking cavities 401 are slidably connected to two shaking boxes 5, the inner wall of the charging box 4 is connected to a shaking mechanism, and the shaking mechanism is against the bottom surface of the outer wall of the two shaking boxes 5, and the upper surfaces of the two shaking boxes 5 are connected to limiting components, and the other ends of the two limiting components are respectively connected to the inner walls of the two shaking cavities 401.

[0024] The raw material proportioning device of the present invention is similar in structure to the existing raw material proportioning device of concrete, such as the raw material proportioning mixing device for concrete production disclosed in the patent with publication number CN219686114U. The main improvement of the present invention is that when the user mixes the concrete raw materials through the mixing body 1, the raw materials can be prevented from sticking to the inner wall of the shaking box 5 under the action of the shaking mechanism under the shaking box 5 in the two shaking chambers 401, thereby avoiding the waste of raw materials. Figures 1 to 5 As shown, when the raw material proportioning device for concrete in the utility model is in use, first, the concrete raw materials to be mixed are placed in the two shaking boxes 5 of the two shaking chambers 401, and then the shaking mechanism is opened by an external controller, and the shaking mechanism drives the two shaking boxes 5 to shake up and down, so that the concrete raw materials stored in the shaking boxes 5 can enter the conveying box 3 along the feed port 301, and then the raw materials are conveyed to the mixing body 1 through the two conveying pipes 2 inside the conveying box 3 for stirring and mixing. Under the shaking of the shaking mechanism, the two shaking boxes 5 can not only shake the raw materials into the conveying box 3 more quickly, but also prevent the raw materials from sticking to the inner wall of the shaking box 5, thereby avoiding waste of raw materials.

[0025] After the mixing is completed, when the two shaking boxes 5 need to be cleaned, it is only necessary to loosen the two limit assemblies to stop limiting the shaking boxes 5, and then the shaking boxes 5 can be manually taken out from the top of the shaking chamber 401, so as to facilitate subsequent cleaning.

[0026] Please refer to Figure 2-Figure 4The shaking mechanism includes a motor 9, a rotating rod 6 and a plurality of elliptical blocks 10. The outer wall of the motor 9 is fixedly connected to one side of the outer wall of the feeding box 4, the output shaft of the motor 9 is fixedly connected to one end of the rotating rod 6, the other end of the rotating rod 6 passes through the feeding box 4 and the plurality of elliptical blocks 10, the outer wall of the rotating rod 6 is rotatably connected to the inner wall of the feeding box 4, the outer wall of the rotating rod 6 is fixedly connected to the inner walls of the plurality of elliptical blocks 10, and the outer walls of the plurality of elliptical blocks 10 are respectively against the bottom surfaces of the outer walls of the two shaking boxes 5.

[0027] More specifically, when it is necessary to control the shaking of the shaking box 5, the switch of the motor 9 is turned on through the external controller. After the motor 9 is started, the output shaft drives the rotating rod 6 to rotate. After the rotating rod 6 rotates, it drives several elliptical blocks 10 to rotate. Because the rotating rod 6 is inserted into one end of the elliptical block 10, the elliptical block 10 can be made narrow at one end and thick at the other end. When the elliptical block 10 switches between the narrow and thick modes, when the thicker end faces upward, the shaking box 5 above will be pushed upward, and when the narrower end faces upward, the shaking box 5 will fall down by itself due to its own gravity and the gravity of the raw materials, so that the shaking box 5 can move up and down, thereby driving the shaking box 5 to achieve the purpose of shaking.

[0028] Please refer to Figure 2-Figure 5 , a plurality of elliptical blocks 10 are evenly divided into two groups, and the two groups of elliptical blocks 10 are respectively located under the two shaking boxes 5, and the elliptical blocks 10 in the same group are evenly distributed under the corresponding shaking boxes 5. By evenly dividing the elliptical blocks 10 into two groups, and evenly distributing the two groups of elliptical blocks 10 under the shaking boxes 5, the shaking boxes 5 can be subjected to a more uniform force and are less likely to tilt or get stuck.

[0029] Please refer to Figure 3-Figure 5 The limiting component includes a card plate 7 and an elastic component. The cross-section of the card plate 7 is L-shaped. The inner walls on both sides of the card plate 7 are respectively against the upper surface and the side of the shaking box 5. One end of the elastic component is connected to the inner wall of the shaking chamber 401, and the other end of the elastic component is connected to the outer wall of one side of the card plate 7.

[0030] More specifically, in the limiting state, the card plate 7, pushed by the elastic component, will limit the upper part of the shaking box 5 against which the inner wall of the card plate 7 is pressed, so that the shaking box 5 can shake up and down without falling off due to excessive shaking amplitude; secondly, the card plate 7 and the elastic component can also prevent the shaking box 5 from moving too much in the direction away from the feed inlet 301, thereby causing the raw materials inside the shaking box 5 to fall into the shaking chamber 401; and when the shaking box 5 needs to be cleaned, it is only necessary to manually compress the elastic component to compress the elastic component, so that the card plate 7 can be separated from the shaking box 5, so that the shaking box 5 can be directly taken out from the top of the shaking chamber 401, which is convenient and easy to operate.

[0031] Please refer to Figure 3-Figure 5 The elastic component includes a plurality of support rods 12 and a plurality of springs 13, and the plurality of springs 13 are respectively sleeved on the outer walls of the plurality of support rods 12, and the same end of the plurality of support rods 12 and the plurality of springs 13 are slidably connected to the outer wall of one side of the clamping plate 7, and the other ends of the plurality of springs 13 are fixedly connected to the inner wall of the shaking chamber 401, and the other ends of the plurality of support rods 12 penetrate the feeding box 4 and are slidably connected to the inner wall of the feeding box 4.

[0032] More specifically, in the limit position, the spring 13 remains in the open state, and the spring 13 at this time will push the card plate 7 forward, so that the card plate 7 can be stuck on the upper surface and side of the shaking box 5. When the shaking box 5 starts to bump up and down at this time, because the spring 13 has a certain elasticity, it will not affect the up and down shaking of the shaking box 5, and because the support rod 12 has no deformation ability, after the shaking box 5 shakes to a certain extent, the upper surface of the shaking box 5 has contacted the support rod 12 inside the spring 13, so it cannot continue to bump up and down. Move upward, so as to avoid the shaking box 5 from popping up from the top; and when the shaking box 5 needs to be taken out later, it is only necessary to pull the support rod 12 to compress the spring 13, so that the card plate 7 can be separated from the shaking box 5, so that the shaking box 5 can be taken out and cleaned; and it should be specially noted here that the sliding of the card plate 7 and the support rod 12 is an inseparable sliding, and the common ones are such as the cooperation of the slide rail and the slide groove. Of course, other methods can also be used. Because it is a very common existing technology, it is not described in detail, and the specific method is not limited.

[0033] Please refer to Figure 1-Figure 4 , a plurality of support rods 12 penetrate one end of the charging box 4 and are connected to a handle 8, and the outer wall of the handle 8 abuts against the outer wall of the charging box 4. By providing the handle 8, it is more convenient to grasp the support rod 12 when the spring 13 needs to be compressed in the later stage.

[0034] Please refer to Figure 3 and Figure 4 The bottom surfaces of the two shaking chambers 401 near the feed port 301 are fixedly connected with pads 11, and the upper surfaces of the two pads 11 respectively abut against the bottom surfaces of the outer walls of the two shaking boxes 5. By providing the pads 11, firstly, a support can be provided for the side of the shaking box 5 away from the shaking mechanism; secondly, because the upper surface of the pads 11 is a slope, the raw materials shaken out of the shaking box 5 can enter the conveying box 3 more smoothly.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
