Description

Technical Field

[0001] This utility model relates to the field of concrete mixing and feeding technology, specifically to a device for adding concrete additives. Background Technology

[0002] A concrete mixer is a specialized piece of equipment used for mixing and blending concrete materials. It can mix water, aggregates, cement, and other additives in a specific ratio to produce concrete that meets the required specifications. When adding various materials into the mixer, a hoist is used for auxiliary operations because aggregates and cement are large in volume and heavy, making manual handling impractical. Furthermore, existing screw hoists have limited conveying speed and lifting capacity.

[0003] For example, the concrete additive feeding device proposed in document number "CN222079682U" describes in the last part of paragraph

[0029] that the feeding cylinder is connected to the internal screw conveyor below. The powder falls through the screen plate into the screw conveyor, and the operator can pull the rope to lift the bag, thereby accelerating the discharge of the powder inside the bag. Starting the motor causes the screw conveyor roller inside the screw conveyor to rotate. The tail end of the screw conveyor can be connected to a mixing tank or a storage cylinder. The powder is conveyed into the mixing tank or storage cylinder. The screen plate installed therein will hinder the material from flowing towards the screw conveyor roller, and the lifting speed and lifting amount of the screw conveyor roller are limited. Therefore, we propose a concrete additive feeding device. Utility Model Content

[0004] This utility model provides a device for adding concrete additives. The hopper has a large loading capacity and can pour raw materials such as stones, additives, and cement into the hopper and introduce them into the mixer together, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: a concrete additive adding device includes a hopper, a guide trough is provided on one side of the top of the hopper at an upward angle, the top two sides of the guide trough are respectively rotatably connected to a support frame, the bottom of the support frame is installed on a support frame, the hopper and the guide trough are both installed on a reinforcing frame, and a lifting hydraulic cylinder is rotatably provided on the bottom of the reinforcing frame at an downward angle, the bottom of the lifting hydraulic cylinder is rotatably connected to the support frame.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1 to 5 This utility model provides a technical solution: a device for adding concrete additives, including a hopper 8, with a guide trough 9 inclined upward on one side of the top of the hopper 8. Both the hopper 8 and the guide trough 9 are mounted on a reinforcing frame, which supports the hopper 8 and the guide trough 9 and prevents them from deforming or bending. Figure 4 As shown, the reinforcing frame includes at least two parallel first reinforcing rods 15, which are connected by second reinforcing rods 18. The first reinforcing rods 15 and the second reinforcing rods 18 are installed below the hopper 8 and the guide trough 9. The first reinforcing rods 15 and the second reinforcing rods 18 form a planar frame structure below the hopper 8 and the guide trough 9. By setting this frame below the hopper 8 and the guide trough 9, the hopper 8 and the guide trough 9 can have greater load-bearing capacity and resistance to deformation.

[0022] The top two sides of the guide trough 9 are rotatably connected to the support frame 10, as follows: Figure 4 As shown, a support shaft 14 is installed below the top of the guide trough 9. When installing the support shaft 14, it is necessary to fix the support shaft 14 to the first reinforcing rod 15 to make the support shaft 14 more stable. The two ends of the support shaft 14 are rotatably connected to the support frame 10, and the bottom of the support frame 10 is installed on the support frame 1.

[0023] The supporting frame 1 as a whole is movable, such as... Figure 1 and Figure 2As shown, a wheel axle 19 is installed below the end of the support frame 1 near the guide chute 9. Two wheels 13 are rotatably mounted on both ends of the wheel axle 19, and the wheels 13 travel on the ground. Supports 2 are respectively provided on both sides of the end of the support frame 1 near the hopper 8. Vertically downward supporting hydraulic cylinders 4 are installed on the supports 2. A supporting plate 3 is located at the bottom of the supporting hydraulic cylinder 4, and the supporting plate 3 is supported on the ground. Together with the wheels 13, the supporting plate 3 and the supporting plate 1 support the support frame 1.

[0024] To facilitate connection between the support frame 1 and the tractor, a U-shaped seat 5 is provided at the middle of the end of the support frame 1 near the hopper 8. A connecting arm 6 is rotatably mounted inside the U-shaped seat 5, meaning that the connecting arm 6 and the U-shaped seat 5 are rotatably connected via a shaft. A connecting hole (e.g., ...) is provided at the end of the connecting arm 6 away from the U-shaped seat 5. Figure 1 (As indicated by arrow B), this connection hole is used to connect to the tractor via a pin.

[0025] The U-shaped base 5 has a pin hole at the end away from the support frame 1 (e.g., Figure 2 (As indicated by arrow A), the pin hole passes through the connecting arm 6. When the connecting arm 6 rotates to the position indicated by arrow A... Figure 1 When the position shown is reached, the pin hole on the connecting arm 6 is connected to the pin hole on the U-shaped seat 5 in the first phase. At this time, the connecting arm 6 and the pin hole are connected by the pin 7, which can stabilize the connecting arm 6. Then, the connecting arm 6 is connected to the tractor, and then the supporting hydraulic cylinder 4 is retracted so that the tractor can drive the device to move.

[0026] It should be noted that although the connecting arm 6 is convenient for connecting to the tractor, it would hinder use if the connecting arm 6 is not retracted. Therefore, a connecting seat 20 is also provided on the side of the support frame 1. When the connecting arm 6 is rotated to the side of the support frame 1, the connecting arm 6 is placed in the connecting seat 20, and the connecting seat 20 is provided with positioning holes (such as...). Figure 1 (As indicated by the middle arrow C), the positioning hole penetrates the connecting arm 6. At this time, the pin 7, which has been pulled out from the U-shaped seat 5, can be inserted into the positioning hole. This not only allows the pin 7 to be stored, but also allows the connecting arm 6 to be stored and fixed again through the pin 7. Figure 2 As shown, the connecting arm 6 is located below the hopper 8 at this time.

[0027] Based on the above embodiments, in practical applications, raw materials such as stones, additives, and cement can be poured together into the hopper 8. The position of the hopper 8 is lower than that of the mixer, which facilitates the transfer of additives and various raw materials into the hopper 8. Figure 5As shown, a downward-sloping lifting hydraulic cylinder 16 is rotatably mounted at the bottom of the reinforcing frame. The top of the lifting hydraulic cylinder 16 is rotatably connected to the reinforcing seat 17, which is fixed to the first reinforcing rod 15. This strengthens the structural strength of the top of the lifting hydraulic cylinder 16. The bottom of the lifting hydraulic cylinder 16 is rotatably connected to the support frame 1. Therefore, when the lifting hydraulic cylinder 16 extends, it can drive the hopper 8 and the guide chute 9 to rotate, allowing the guide chute 9 to rotate around the support frame 10. The specific details are as follows. Figure 5 As shown, when the hopper 8 rotates to the top of the mixer, the material in the hopper 8 will enter the mixer along with the guide chute 9. The guide chute 9 is constricted, so that the top of the guide chute 9 can pour the material into the mixer with a smaller area. The hopper 8 is long and narrow, which not only increases the storage space, but also makes it convenient for the loader to load material.

[0028] Based on the above embodiments, further optimization can be achieved by providing a control cabinet 11 on the top of the support frame 1 near the support frame 10. The control cabinet 11 contains a hydraulic station and a controller. The hydraulic cylinders are connected to the lifting hydraulic cylinder 16 and the supporting hydraulic cylinder 4 respectively through oil pipes. The controller is connected to the hydraulic station. Furthermore, an operation button 12 is provided on the surface of the control cabinet 11, and the operation button 12 is connected to the controller.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
