Technical Field
[0001] This utility model relates to the field of mixing machine technology, specifically a concrete mixing machine capable of quantitative material feeding. Background Technology
[0002] Concrete is an artificial stone material made by mixing cement, aggregates and water in a specific ratio and then hardening. Aggregates are divided into two categories: fine aggregates and coarse aggregates. Coarse aggregates are further classified into pebbles, crushed stone, broken pebbles, and mixtures of pebbles and crushed stone. Before use, coarse aggregates need to be mixed using a mixer to improve the performance of the subsequent concrete.
[0003] In the existing technology, concrete mixers are special equipment used in construction engineering to mix concrete materials. In the process of mixing aggregates, traditional mixers usually require manual feeding. Manual feeding can easily result in the addition of too much or too little raw material, which will affect the performance of the subsequent concrete. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4 It is understood that this utility model provides a technical solution: a concrete mixer with quantitative feeding capability, including a mixing box 1, a support frame 2, a drive motor 3, a mixing shaft 4, and a cover plate 5. A support frame 6 is connected to the top of the cover plate 5. A feeding bucket 7 is provided on the inner side of the support frame 6. A weighing sensor 8 is installed between the outer side of the feeding bucket 7 and the top of the support frame 6. A guide pipe 9 is connected to the bottom of the feeding bucket 7. Two sets of support plates 10 are connected to the top of the cover plate 5. A rotating rod 11 is rotatably connected between the two sets of support plates 10 through bearings. A circular baffle 12 is connected to the outer side of the rotating rod 11 near the guide pipe 9.
[0023] The concrete mixer with metered feeding function has a circular baffle 12 used to block and open the internal channel of the feed pipe 9.
[0024] exist Figures 1-4 In the middle: a gear 13 is connected to the outer side of the rotating rod 11 away from the circular baffle 12, and a cylinder 14 is installed on the surface of the cover plate 5 near the gear 13. The telescopic end of the cylinder 14 is connected to a toothed plate 15.
[0025] The concrete mixer with metered feed function has a cylinder 14 that controls the opening and closing of the circular baffle 12.
[0026] exist Figure 3 and Figure 4 In the middle: the toothed plate 15 and the gear 13 form a meshing structure, the circular baffle 12 is located inside the guide tube 9, and the cover plate 5 has a feed inlet through the inside of the guide tube 9.
[0027] The concrete mixer with quantitative feeding capability has a feed pipe 9 that is connected to the feed inlet of the cover plate 5.
[0028] In practical implementation, a concrete mixer is a concrete material mixing equipment. Traditional mixers are difficult to quantitatively add materials, resulting in the addition of more or less raw materials, which can easily lead to material waste and affect the subsequent concrete performance. First, the raw materials are poured into the feeding bucket 7. At this time, the circular baffle 12 is in a blocked state, so that the raw materials can fall onto the circular baffle 12. The weighing sensor 8 can weigh the raw materials inside the feeding bucket 7. At this time, the operator can start the cylinder 14 according to the weight of the raw materials inside the feeding bucket 7. When the cylinder 14 is running, its extension end can drive the toothed plate 15 to push away from the cover plate 5. When the toothed plate 15 moves, it can mesh and drive the gear 13 to rotate. When the gear 13 rotates, it can drive the rotating rod 11 to rotate. When the rotating rod 11 rotates, it can drive the circular baffle 12 to rotate. When the circular baffle 12 rotates, it can open the channel inside the guide pipe 9, so that the raw materials inside the feeding bucket 7 can fall into the mixing box 1 through the guide pipe 9 and the feed inlet of the cover plate 5.
[0029] See Figures 1-4 It is known that when enough raw materials are added, the cylinder 14 can contract, thereby blocking the guide pipe 9 through the circular baffle 12, preventing the raw materials from falling further. The weighing sensor 8 allows personnel to add materials quantitatively according to the actual situation, thus preventing the addition of too much or too little raw materials, avoiding waste of raw materials and affecting the subsequent concrete performance.
[0030] exist Figure 1 , Figure 2 and Figure 5 In the middle: A forward and reverse motor 16 is installed on the top of the support frame 2. The output end of the forward and reverse motor 16 is connected to a threaded rod 17 through a bearing. A movable plate 18 is threadedly connected to the outer side of the threaded rod 17. A support base 19 is connected to the top of the movable plate 18.
[0031] The concrete mixer with metered feeding has a sliding structure between the support base 19 and the mixing box 1.
[0032] exist Figure 1 , Figure 2 and Figure 5 In the middle: a stop block 20 is connected to the bottom of the support base 19 near the inner wall of the mixing box 1, a vibration spring 21 is connected to the top of the support base 19, a guide frame 22 is connected to the top of the four sets of vibration springs 21, and a small electric vibrator 23 is installed at the bottom of the guide frame 22.
[0033] The concrete mixer with metered feeding function has a stop block 20 used to limit the material guide 22 when it moves away from below the feed inlet of the cover plate 5, so that the material guide 22 cannot continue to move.
[0034] In practice, after the concrete mixer finishes feeding, if there is any remaining material inside the feeding hopper 7, the forward and reverse motor 16 can be started. When the forward and reverse motor 16 rotates forward, it can drive the threaded rod 17 to rotate. When the threaded rod 17 rotates, it can drive the moving plate 18 to slide threadedly towards the mixing box 1. When the moving plate 18 moves, it can drive the support base 19 to move. When the support base 19 moves, it can drive the stop block 20 and the guide frame 22 to move. When the top end of the guide frame 22 moves to the cover plate 5... When the material is directly below the feed inlet, a receiving bucket can be placed below the end of the guide frame 22 away from the mixing box 1. The receiving bucket is not shown in the figure. Then, the cylinder 14 is activated to open the circular baffle 12, so that the remaining raw material inside the feeding bucket 7 can fall into the guide frame 22 through the feed pipe 9 and the feed inlet of the cover plate 5. Then, the small electric vibrator 23 is activated. Through the small electric vibrator 23 and the vibration spring 21, the raw material inside the guide frame 22 can slide along the inclined surface of the inner wall of the guide frame 22 by vibration.
[0035] See Figure 1 , Figure 2 and Figure 5 It can be seen that when the raw material slides out from inside the guide frame 22, it can fall into the receiving bucket below, so that the remaining raw material inside the feeding bucket 7 can be easily and conveniently discharged through the guide frame 22.
[0036] In summary, when using this quantitatively feedable concrete mixer, the weighing sensor 8 can weigh the raw materials inside the feeding hopper 7. At this time, the operator can start the cylinder 14 according to the weight of the raw materials inside the feeding hopper 7. When the cylinder 14 is running, its telescopic end can drive the toothed plate 15 to push away from the cover plate 5. The weighing sensor 8 allows the operator to quantitatively feed according to the actual situation, so that it is not easy to add too much or too little raw materials, and it is not easy to cause waste of raw materials and affect the subsequent concrete performance. When the raw materials slide out from the inside of the guide frame 22, they can fall into the receiving hopper below. Thus, the remaining raw materials inside the feeding hopper 7 can be easily and conveniently discharged through the guide frame 22. The contents not described in detail in this description are existing technologies known to those skilled in the art.
[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
