Technical Field

[0001] This utility model relates to the technical field of concrete feeding devices, and in particular to a high-strength concrete steel fiber feeding device that is easy to weigh. Background Technology

[0002] Adding steel fibers to concrete can improve its crack resistance and increase its tensile strength, making it more adaptable to complex and changing stress environments. To reduce costs, manual feeding is often used when adding steel fibers. Workers carry bags containing steel fibers and put them into the concrete mixing plant. To ensure the steel fibers are evenly distributed, workers control the bag opening with one hand and lift the bag with the other, adding small amounts of steel fibers continuously. However, manual feeding is not suitable for large-scale concrete processing equipment. Therefore, mechanical feeding is used to add steel fibers into the concrete mixing plant.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] This utility model provides a technical solution:

[0026] See also Figures 1 to 4 A high-strength concrete steel fiber feeding device for easy weighing includes a weighing box 1, a weighing plate 6 for weighing is installed at the bottom of the weighing box 1, and the size of the weighing plate 6 matches the bottom size of the weighing box 1. A pushing component 2 for pushing the steel fiber is provided above the weighing plate 6, and a discharge trough 4 for discharging is fixedly provided at the front end of the weighing box 1. A discharge port 5 is opened at the bottom of the discharge trough 4.

[0027] The discharge trough 4 is equipped with a vibration component 3 for breaking up steel fibers. A fixed bracket 7 is fixedly installed below the weighing box 1, and the discharge trough 4 and the weighing box 1 are connected to each other.

[0028] By adopting the above technical solution, the discharge port 5 is located above the inlet of the concrete mixing device. The steel fibers to be added to the concrete are directly poured into the weighing box 1 and weighed by the weighing plate 6 inside the weighing box 1. The weighing plate 6 can be an existing flat-plate weighing device. The weighing plate of the flat-plate weighing device can be matched with the height of the pushing component 2. A display for displaying the weight can be set on the surface of the weighing box 1. The display is electrically connected to the weighing plate 6. The weight of the steel fibers can be viewed through the display. The electrical connection between the display and the flat-plate weighing device is a publicly available technology of existing weighing devices. Here, only the weighing device is used to achieve the weighing effect. Its detailed working principle will not be elaborated. When the specified weight is reached, the worker stops pouring the steel fibers. The steel fibers can be pushed to the discharge trough 4 by the pushing component 2 and then discharged outward by the vibration component 3 inside the discharge trough 4, thus realizing the feeding of steel fibers.

[0029] Specifically, such as Figure 2 As shown, a partition plate 205 is provided at the connection between the discharge trough 4 and the weighing box 1, and a connecting shaft 206 is provided at the top of the partition plate 205. The partition plate 205 is rotatably installed at the inlet position of the discharge trough 4 through the connecting shaft 206. The pushing assembly 2 includes a pushing hydraulic cylinder 202 fixed to the rear side of the weighing box 1, and the telescopic end of the pushing hydraulic cylinder 202 passes through the weighing box 1 and is fixedly connected to a pushing plate 201. A rubber strip is provided at the bottom of the pushing plate 201, and the rubber strip is in contact with the top of the weighing plate 6. A push rod 204 is installed on the surface of the pushing plate 201, and the end of the push rod 204 is installed on the partition plate 205. A connecting piece 203 is provided at the connection between the push rod 204 and the pushing plate 201 and the partition plate 205, and the push rod 204 and the connecting piece 203 are connected by a pin.

[0030] By adopting the above technical solution, when the material is weighed to a suitable weight and feeding is required, the pushing hydraulic cylinder 202 can be activated. After the extension end of the pushing hydraulic cylinder 202 is pushed out, it pushes the pushing plate 201 to slide on the top of the weighing plate 6, and the distance between the pushing plate 201 and the discharge trough 4 becomes shorter. At the same time, the pushing rod 204 pushes the partition plate 205 to rotate on the discharge trough 4 through the connecting shaft 206. At this time, a certain angle is formed between the partition plate 205 and the discharge trough 4, and the steel fiber can enter the interior of the discharge trough 4 through the open partition plate 205. As the pushing rod 204 pushes, the partition plate 205 rotates, and the pushing rod 204 is angled on the connecting piece 203 through the pin, so that the pushing rod 204 rotates in coordination with the arc movement of the partition plate 205.

[0031] Specifically, such as Figure 3As shown, the vibration assembly 3 includes a vibration motor 301 fixed on the surface of the discharge trough 4, and the power output end of the vibration motor 301 passes through the discharge trough 4 and is connected to a vibration plate 302. Several connecting springs 305 are evenly distributed at equal intervals at the connection between the vibration plate 302 and the discharge trough 4. A discharge port 304 is opened in the middle of the vibration plate 302, and a discharge bag 303 is arranged below the discharge port 304. The discharge bag 303 passes through the interior of the discharge port 5.

[0032] By adopting the above technical solution, when the vibration motor 301 is started, the vibration motor 301 can drive the vibration plate 302 to vibrate. After the steel fibers reaching the top of the vibration plate 302 are dispersed, they are discharged into the discharge bag 303 through the discharge outlet 304 and slide down into the concrete mixing device. Since the size of the discharge outlet 304 is small and the number of steel fibers passing through the discharge outlet 304 is limited, a large number of steel fibers can be prevented from entering the concrete mixing device at the same time, which facilitates the uniform addition of steel fibers to the concrete.

[0033] Working principle: The discharge port 5 is located above the inlet of the concrete mixing device. The steel fibers to be added to the concrete are poured directly into the weighing box 1 and weighed by the weighing plate 6 inside the weighing box 1. The surface of the weighing box 1 can be equipped with a display for showing the weight. The display is electrically connected to the weighing plate 6. When the worker observes that the steel fibers have reached the specified weight, the pouring of steel fibers is stopped. When feeding is needed, the pushing hydraulic cylinder 202 is activated. After the extension end of the pushing hydraulic cylinder 202 is extended, it pushes the pushing plate 201 to slide on the top of the weighing plate 6. The distance between the pushing plate 201 and the discharge chute 4 becomes shorter. At the same time, the pushing rod 204 pushes the partition plate 205 through the connecting rod. When the shaft 206 rotates on the discharge trough 4, the partition plate 205 and the discharge trough 4 form a certain angle. The steel fibers can enter the interior of the discharge trough 4 through the open partition plate 205. The vibration motor 301 can drive the vibration plate 302 to vibrate. After the steel fibers reach the top of the vibration plate 302 are dispersed, they are discharged into the discharge bag 303 through the discharge outlet 304 and slide down into the concrete mixing device. Since the size of the discharge outlet 304 is small and the number of steel fibers passing through the discharge outlet 304 is limited, a large number of steel fibers can be prevented from entering the concrete mixing device at the same time, which makes it easier for the steel fibers to be added evenly to the concrete.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
