Description

Technical Field

[0001] The utility model belongs to the technical field of concrete, and in particular relates to a batching and feeding mechanism for concrete preparation. Background Art

[0002] Concrete is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. Concrete is the main civil engineering material. It is an artificial building material that is prepared in a certain proportion from cementitious materials, granular aggregates, water, admixtures and mixed ingredients, and is made through uniform mixing, dense molding, and curing and hardening.

[0003] It is necessary to add a variety of ingredients when preparing concrete. The existing workers not only have a high labor intensity, but also need to pour the materials near the adjacent side of the top of the concrete preparation tank during the pouring of the composite admixture. The safety of the workers' operation is difficult to ensure. In response to the above technical problems, the applicant has retrieved some prior arts, such as the Chinese patent with patent publication number CN217891404U. When in use, the ingredients are placed in a storage barrel, and then the ingredients are poured into the concrete preparation tank by pouring the storage barrel. However, it is just a simple transportation of materials. Multiple ingredients are piled together and enter the concrete preparation tank. It takes a lot of time to mix the multiple ingredients evenly, which reduces the preparation efficiency of concrete. At the same time, the materials are stationary in the storage barrel and only move when pouring, so that it is easy for ingredients to remain in the storage barrel, reducing the efficiency of feeding. Summary of the invention

[0004] The utility model aims to provide a batching feeding mechanism for concrete preparation, aiming to solve the technical problems in the prior art that the batching cannot be evenly mixed and the batching is easily left in the device.

[0005] The utility model is implemented as follows: a concrete preparation batching feeding mechanism comprises a concrete preparation tank body, a guide frame is fixedly installed on the side of the feeding end of the concrete preparation tank body, a movable plate driven by a screw module is slidably installed on the guide frame, two groups of spaced-apart mounting plates are fixedly installed on the movable plate, and a barrel is rotatably installed on the two groups of mounting plates, and one group of the mounting plates is provided with a power component for driving the barrel to rotate and a sealing component for blocking the opening of the discharge end of the barrel.

[0006] Further technical solution: the barrel is a truncated cone structure with both ends being open structures, and the end with a larger opening of the barrel points to the concrete preparation tank.

[0007] Further technical solution: the end with the smaller opening of the barrel is used in conjunction with a feed hopper fixedly mounted on the mounting plate, and the discharge end of the feed hopper is provided with a material guide trough fixedly mounted on a movable plate, the material guide trough is set at an angle with the horizontal plane and its lower end extends into the barrel.

[0008] Further technical solution: the power assembly includes a rotating power part, which is fixedly mounted on the mounting plate and drives the gear to rotate. The axis of the output shaft of the rotating power part is parallel to the axis of the barrel, and the gear is meshed with a gear ring fixedly mounted on the barrel.

[0009] Further technical solution: the gear ring is distributed around the barrel and is arranged coaxially with the barrel.

[0010] Further technical solution: the sealing assembly includes a support plate, which is located at the end of the barrel and is driven by multiple sets of telescopic parts fixedly mounted on the mounting plate. A baffle is rotatably mounted on the mounting plate close to the surface of the barrel.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. During the filling and transportation process, the rotation of the barrel drives the ingredients inside to tumble, which improves the fluidity of the ingredients. Under the action of tumbling, various ingredients are impact-mixed, which improves the uniform mixing degree of the ingredients.

[0013] 2. When unloading, the barrel rotates, causing the ingredients inside to turn over, increasing the fluidity of the ingredients inside, making it easier for the ingredients to leave the barrel, facilitating the subsequent unloading of ingredients, reducing the residual ingredients in the barrel, and improving the efficiency of loading.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0020] like Figure 1-Figure 3 As shown, a concrete preparation batching feeding mechanism provided by the utility model comprises a concrete preparation tank body 1, a guide frame 2 is fixedly installed on the side of the feeding end of the concrete preparation tank body 1, a moving plate 3 driven by a screw module 4 is slidably installed on the guide frame 2, two groups of spaced-apart mounting plates 5 are fixedly installed on the moving plate 3, and a barrel 6 is rotatably installed on the two groups of mounting plates 5, one group of the mounting plates 5 is provided with a power component 15 for driving the barrel 6 to rotate and a sealing component 16 for blocking the opening of the discharge end of the barrel 6.

[0021] In actual application of this embodiment, the screw module 4 drives the movable plate 3 to move on the guide frame 2 toward the end away from the concrete preparation tank 1, and the sealing component 16 is used to block the feeding end of the barrel 6. Then, a variety of ingredients can be added to the barrel 6. At this time, the power component 15 drives the barrel 6 to rotate, and the rotation of the barrel 6 drives the ingredients inside it to roll, thereby improving the fluidity of the ingredients. Under the action of rolling, the various ingredients are impact-mixed, thereby improving the uniform mixing degree of the ingredients. After adding an appropriate amount of ingredients to the barrel 6, the screw module 4 drives the movable plate 3 to move toward the end of the concrete preparation tank 1. The movable plate 3 moves toward one side of the concrete preparation tank body 1 while keeping the barrel 6 rotating. When the discharge end of the barrel 6 moves to the top of the concrete preparation tank body 1, the sealing assembly 16 is released from the discharge end of the barrel 6, and then the ingredients can fall downward from the barrel 6 into the concrete preparation tank body 1. As the barrel 6 rotates, the ingredients inside it are turned over, increasing the fluidity of the ingredients inside, making it easier for the ingredients to leave the barrel 6, facilitating the subsequent unloading of ingredients, reducing the residual ingredients in the barrel 6, and improving the efficiency of loading.

[0022] like Figure 1-Figure 3 As shown, a concrete preparation batching feeding mechanism provided by the utility model is provided, wherein the barrel 6 is a truncated cone structure and both ends thereof are open structures, and the end with a larger opening of the barrel 6 points to the concrete preparation tank 1.

[0023] Specifically, the end with the smaller opening of the barrel 6 is used in conjunction with a feed hopper 7 fixedly mounted on the mounting plate 5, and the discharge end of the feed hopper 7 is provided with a guide trough 8 fixedly mounted on the movable plate 3. The guide trough 8 is set at an angle with the horizontal plane and its lower end extends into the barrel 6.

[0024] In actual application of this embodiment, the ingredients fall downward into the material guide trough 8 through the feed hopper 7. Since the material guide trough 8 is inclined, the ingredients will enter the barrel 6 along the material guide trough 8. Since the barrel 6 is a truncated cone structure, the side with a larger opening on the lower side of the inner wall is lower, and the subsequent ingredients will move to the side with a larger opening of the barrel 6, which is convenient for the subsequent comprehensive feeding of the ingredients.

[0025] like Figure 1-Figure 3 As shown, a concrete preparation batching feeding mechanism provided by the utility model is provided, the power assembly 15 includes a rotating power member 9, the rotating power member 9 is fixedly mounted on the mounting plate 5 and drives the gear 10 to rotate, the axis of the output shaft of the rotating power member 9 is parallel to the axis of the barrel 6, and the gear 10 is meshed with a gear ring 11 fixedly mounted on the barrel 6.

[0026] Specifically, the gear ring 11 is distributed around the barrel 6 and is arranged coaxially with the barrel 6 .

[0027] In actual application of this embodiment, the rotating power part 9 drives the barrel 6 to rotate through the meshing gear 10 and the ring gear 11, so that the ingredients in the barrel 6 are mixed evenly, and at the same time, the ingredients in the barrel 6 flow, which facilitates the subsequent feeding of ingredients and reduces the residue of ingredients in the barrel 6.

[0028] In an example of the present invention, the rotating power member 9 is a motor, and of course it can also be other components capable of outputting rotating power, such as a hydraulic motor. The motor drives the barrel 6 to rotate, thereby improving the fluidity of the material.

[0029] like Figure 1-Figure 3 As shown, a concrete preparation batching feeding mechanism provided by the utility model, the sealing assembly 16 includes a support plate 13, the support plate 13 is located at the end of the barrel 6 and is driven by multiple groups of telescopic parts 12 fixedly mounted on the mounting plate 5, and a baffle 14 is rotatably installed on the surface of the mounting plate 5 close to the barrel 6.

[0030] In actual application of this embodiment, when transporting ingredients, the telescopic member 12 drives the support plate 13 to approach the barrel 6, so that the baffle 14 contacts the end surface of the barrel 6, and then the opening of the barrel 6 is closed by the baffle 14. When the barrel 6 rotates subsequently, the baffle 14 can rotate simultaneously with the barrel 6 to ensure the sealing effect. When unloading, the telescopic member 12 drives the support plate 13 away from the barrel 6. At this time, the baffle 14 leaves the barrel 6 and the ingredients can leave from the opening of the barrel 6.

[0031] In an example of this embodiment, the telescopic member 12 is an electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The electric telescopic rod drives the baffle 14 to move, thereby achieving the closure of the barrel 6.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
