The cover plate is fixedly installed at one end of an electric telescopic rod and is installed at the lower end of a mixing container. The top of the mixing container is provided with a first feed port and a second feed port, and scraping blades are provided on the inner wall of the mixing container. The machine of the utility model stirs the concrete, improves the work efficiency and the accuracy of stirring. Through the arrangement of the limiting block and the fixing block, the template is prevented from falling off the vibrating table, saving time and effort and improving the work efficiency. Through the arrangement of the workbench and the vibrator, the concrete in the template is fully filled and compacted, improving the quality of test block production.

[0004] In the prior art, the stirring of concrete is realized through a scraping blade similar to a screw rod, so that the concrete can be quickly discharged, but there are many deficiencies in the overall effect: First, the overall volume of the pouring cylinder is large, and a single screw rod cannot effectively stir the concrete particles at various parts inside the cylinder, resulting in many stirring dead corners. Second, the fluidity of the concrete is poor and it is easy to accumulate at the bottom of the pouring cylinder. When the time is too long, it is easy to solidify into blocks, resulting in the pouring efficiency and accuracy not being guaranteed. The prior art lacks a dredging structure and setting for the bottom. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a pouring device for forming concrete test blocks. Through the arrangement of a screw rod, a planetary gear set, a rectangular frame, and scraping strips, etc., during the process of rotating and stirring the screw rod, a large area of secondary agitation of the concrete can also be formed outside the screw rod, effectively improving the stirring and mixing effect. And through the arrangement of a conical surface disc and a vibrator, etc., the flow efficiency of the concrete at the bottom of the pouring cylinder is effectively improved, ensuring the pouring effect and quality.

[0006] To achieve the above object, the utility model provides the following technical solutions: A pouring device for forming concrete test blocks, including a pouring cylinder and a feeding port.

[0023] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Embodiment 1:

[0024] Refer to Figures 1-7 , a pouring device for forming concrete test blocks, including a pouring cylinder 58 and a feeding port 60. A plurality of feeding ports 60 are arranged on the upper end surface of the pouring cylinder 58. Below the feeding port 60, a screw rod 61 is rotatably arranged in the pouring cylinder 58. A fixed frame 66 is fixedly arranged in the pouring cylinder 58 outside the screw rod 61. A planetary gear set is arranged at the bottom of the fixed frame 66. The planetary gear set is driven by the screw rod 61. A plurality of rectangular frames 62 are connected and arranged outside the planetary gear set. The arrangement of the planetary gear set can drive the plurality of rectangular frames 62 outside to rotate outside the screw rod 61.

[0025] Outside each rectangular frame 62, a scraping strip 63 is connected and arranged to enhance the scraping effect. Below the rectangular frame 62, at the bottom of the pouring cylinder 58, a plurality of discharge ports 65 are provided. Between the discharge ports 65, a vibrator 71 is arranged at the bottom of the pouring cylinder 58. The output end of the vibrator 71 will vibrate the bottom of the pouring cylinder 58, thereby vibrating the concrete flowing to the bottom of the pouring cylinder 58, and thus improving the flowing effect of the concrete.

[0026] Specifically, the bottom of the pouring cylinder 58 is conical, and is used to store concrete and stir and mix the concrete. A plurality of feeding ports 60 on the upper end face are used to pour the concrete raw materials. The discharge ports 65 arranged at the bottom of the pouring cylinder 58 can pour the stirred concrete into the mold.

[0027] One end of the top of the screw rod 61 is rotatably connected to the upper end face of the pouring cylinder 58, and the bottom end extends to the bottom of the pouring cylinder 58. When the concrete needs to be mixed, it will rotate, thereby stirring the concrete.

[0028] The end face of the fixed frame 66 is disc-shaped and is fixed on the inner end face of the top of the pouring cylinder 58. The top of the screw rod 61 passes through the end face of the fixed frame 66 and is connected to the top end face of the pouring cylinder 58. When the screw rod 61 rotates, the fixed frame 66 remains stationary. The planetary gear set below the fixed frame 66 cooperates with the outer cylindrical surface of the screw rod 61. When the screw rod 61 rotates, the planetary gear set will be driven to rotate, thereby driving a plurality of external rectangular frames 62 to rotate outside the screw rod 61, thereby forming a secondary rotational stirring outside the screw rod 61. The rectangular frame 62 is integrally in a frame shape and can stir the concrete over a large area.

[0029] A detachable scraping strip 63 is arranged on the outer end face of the rectangular frame 62. The outer end face of the scraping strip 63 is attached to the inner wall of the pouring cylinder 58. During the rotation of the rectangular frame 62, the scraping strip 63 can be driven to scrape the inner wall of the pouring cylinder 58, so that the concrete particles adhered to the inner wall of the pouring cylinder 58 can be scraped off and stirred by the screw rod 61 and the rectangular frame 62, effectively improving the mixing effect. In this relationship, the outer end face of the rectangular frame 62 and the shape of the scraping strip 63 are set according to the change of the inner wall of the pouring cylinder 58, so that the scraping strip 63 can effectively adhere to the inner wall of the pouring cylinder 58 to ensure the scraping effect.

[0030] When the concrete needs to be poured through the discharge port 65 after being stirred, a plurality of screw rods 61 and rectangular frames 62 will be in a rotating state, making the concrete in a stirred state. At this time, the output end of the vibrator 71 at the bottom of the pouring cylinder 58 will vibrate the bottom of the pouring cylinder 58, thereby vibrating the concrete flowing to the bottom of the pouring cylinder 58, and thus improving the flowing effect of the concrete, ensuring the pouring efficiency.

[0031] ReferenceFigure 6 , the planetary gear set includes a sun gear 72 fixedly connected to the outer cylindrical surface of the screw rod 61. A plurality of planet gears 73 are externally meshed with the sun gear 72. The planet gears 73 rotate at a fixed point. A plurality of internal gears 74 are externally meshed with the plurality of planet gears 73. A rectangular frame 62 is connected to the outer cylindrical surface of the internal gear 74.

[0032] Specifically, the plurality of planet gears 73 rotate at a fixed point on the end face of the fixed frame 66. When the screw rod 61 rotates, the screw rod 61 will drive the sun gear 72 to rotate, thereby driving the planet gears 73 meshed with the sun gear 72 to rotate. Since the planet gears 73 rotate at a fixed point, the planet gears 73 will drive the internal gears 74 meshed with them to rotate at the bottom of the fixed frame 66. One end of the rectangular frame 62 is connected to the outer cylindrical surface of the internal gear 74. Therefore, when the internal gear 74 rotates, it can drive the rectangular frame 62 to rotate outside the screw rod 61. The setting of the planetary gear set effectively guarantees and improves the mixing effect through the stable transmission ratio between the gears.

[0033] Reference Figure 5 , a detachable conical disk 67 is provided on the bottom end face of the screw rod 61. The conical disk 67 and the plurality of rectangular frames 62 are connected by a second connecting plate 68.

[0034] Specifically, a connecting rod is provided on the top of the conical disk 67, and a rotating hole is provided at the bottom of the screw rod 61. The connecting rod on the top of the conical disk 67 is rotationally connected and matched with the rotating hole at the bottom of the screw rod 61. The bottom of the conical disk 67 is in a conical shape that converges downward, having the effect of guiding the concrete to be agitated in the center. When the rectangular frame 62 rotates around the screw rod 61, it can drive the second connecting plate 68 to rotate, thereby driving the conical disk 67 to rotate. The connection setting of the plurality of second connecting plates 68 ensures the coaxiality between the plurality of rectangular frames 62 and the screw rod 61 when they rotate, making the plurality of rectangular frames 62 and the screw rod 61 form a rotating whole, effectively improving the stability of the screw rod 61 and the plurality of rectangular frames 62 during stirring.

[0035] Reference Figure 4 , a driving motor 59 is provided on the top end face of the pouring cylinder 58. The output end of the driving motor 59 is connected to the end face of the screw rod 61.

[0036] Specifically, the driving motor 59 is a prior art and will not be elaborated herein. The output end of the driving motor 59 can drive the screw rod 61 to rotate, thereby completing the mixing process of the concrete.

[0037] Reference Figure 5 , a pressure plate 69 is provided outside the output end of the vibrator 71. The top end face of the pressure plate 69 abuts against the end face of the second connecting plate 68. A spring 70 is connected between the pressure plate 69 and the output end of the vibrator 71.

[0038] Specifically, a fixed bracket is provided between the vibrator 71 and the outside of the pouring cylinder 58, so that the vibrator 71 can always be fixed at the bottom of the pouring cylinder 58. The spring 70 has an elastic connection effect and can always push the pressure plate 69 outwards, so that one end of the top of the pressure plate 69 abuts against the bottom end face of the pouring cylinder 58 for a long time, enabling the vibration generated at the output end of the vibrator 71 to be stably transmitted to the bottom of the pouring cylinder 58, improving the flow efficiency of the concrete.

[0039] Reference Figures 1-3 , a pouring table 57 is provided at the bottom of the pouring cylinder 58.

[0040] Specifically, the staff can place a mold on the end face of the pouring table 57 below the discharge port 65, so that the poured concrete can smoothly pour into the mold to complete the pouring work. Embodiment 2:

[0041] Based on or different from Embodiment 1, reference Figures 4-5 , a first connecting plate 64 is connected and arranged inside the rectangular frame 62.

[0042] Specifically, the first connecting plate 64 is similar to a reinforcing rib plate and is arranged on the side of the rectangular frame 62 away from the pouring cylinder 58 to connect and reinforce one end of the top and one end of the bottom of the rectangular frame 62. On the one hand, the first connecting plate 64 improves the overall strength of the rectangular frame 62, enabling the rectangular frame 62 to stir the concrete more stably. On the other hand, it also increases the contact area with the concrete, increasing the stirring area, so that the device can complete a large amount of concrete mixing and processing.
