Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, and in particular to a concrete aggregate feeding device. Background Technology

[0002] Concrete is an artificial stone material made by mixing cementitious materials, aggregates, water, and, if necessary, admixtures and additives in a certain proportion, followed by uniform mixing, compaction, and curing. Aggregates are granular, loose materials that act as a skeleton or filler in concrete.

[0003] Chinese utility model patent CN222345946U discloses a concrete aggregate feeding device, including a base plate, a hopper, and a feeding pipe. A support frame is mounted on the upper end of the base plate, and the hopper is mounted on the support frame. A first motor and a feed hopper are mounted on the upper end of the hopper. A dispersing component is installed inside the hopper, driven and connected to the dispersing component by the first motor. A conveying pipe is installed at the lower end of the hopper, communicating with the feeding pipe. The feeding pipe is inclined on the base plate, and a support rod is installed between the feeding pipe and the base plate. A discharge pipe is installed at the lower end of the feeding pipe. A second motor is installed outside the feeding pipe, and a screw feeder is installed inside the feeding pipe, driven and connected to the screw feeder by the second motor. This feeding device disperses the concrete aggregate inside the hopper using the dispersing component, thereby preventing aggregate clumping and improving aggregate dispersion.

[0004] The feeding device disclosed in the aforementioned utility model patent uses a spiral conveyor rod to transport aggregates along the feeding pipe to achieve feeding. However, since the feeding pipe is fixed on the base plate, the orientation and tilt angle of the feeding pipe on the base plate cannot be adjusted. Therefore, the position of the aggregate discharged from the discharge pipe is fixed, and the discharge height and orientation of the aggregate cannot be adjusted according to the feeding end of the receiving equipment. As a result, the feeding device cannot feed different models of equipment, making it inconvenient to use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a concrete aggregate feeding device that solves the problem that existing feeding devices cannot adjust the aggregate discharge height and orientation.

[0006] According to an embodiment of this utility model, a concrete aggregate feeding device includes a base, on which a rotating platform rotatable in a vertical direction and a first driving member pulsatingly connected to the rotating platform are provided. A guide pipe rotatable in a horizontal direction and a second driving member pulsatingly connected to the guide pipe are provided on the rotating platform. A rotatable conveying rod is provided inside the guide pipe, and a third driving member pulsatingly connected to the conveying rod is provided on the guide pipe. A spiral blade is provided on the conveying rod. An inlet pipe and a outlet pipe are respectively provided at both ends of the guide pipe. A first hemispherical shell is provided at the end of the inlet pipe away from the guide pipe. A feeding hopper is also provided on the base. A conveying pipe is provided at the bottom of the feeding hopper, and a second hemispherical shell that cooperates with the first hemispherical shell is provided at the end of the conveying pipe away from the feeding hopper.

[0007] Furthermore, the base is provided with a receiving groove, and the rotating platform is rotatably disposed within the receiving groove.

[0008] Furthermore, the base is provided with a first through hole communicating with the receiving groove, the rotating platform is provided with a connecting shaft and the connecting shaft passes through the first through hole, the first driving component includes a first motor, and the connecting shaft cooperates with the output end of the first motor.

[0009] Furthermore, the rotating platform is provided with a support and a detachable pressure block is provided on the support, and the first hemispherical shell is provided with a mounting shaft. The support and the pressure block form a mounting hole that mates with the mounting shaft.

[0010] Furthermore, the first hemispherical shell is provided with a detachable connecting ring, which together with the first hemispherical shell forms a spherical groove for accommodating the second hemispherical shell, and the connecting ring is provided with a clearance hole to avoid the mounting shaft.

[0011] Furthermore, the connecting ring includes two semi-ring bodies, each of which is provided with a first through hole, and the first hemispherical shell is provided with a second through hole that is aligned with the first through hole.

[0012] Furthermore, the second driving component includes a cylinder and a piston rod disposed at the output end of the cylinder. The cylinder is rotatably connected to the rotating table, and the piston rod is rotatably connected to the guide tube.

[0013] Furthermore, the third driving component includes a second motor, and the guide tube is provided with a second through hole for the conveying rod to pass through, and the conveying rod cooperates with the output end of the second motor.

[0014] Furthermore, the base is provided with a plurality of legs spaced apart along the axial direction of the base, and each leg is provided with a caster wheel.

[0015] Compared with the prior art, this utility model has the following beneficial effects: By using a first hemispherical shell on the feed pipe and a second hemispherical shell on the conveying pipe to movably connect the guide pipe and the feed hopper, the aggregate input into the feed hopper can enter the guide pipe along the conveying pipe and the feed pipe. At the same time, the guide pipe remains connected to the feed hopper when rotating relative to the feed hopper in any direction. Thus, the first driving component drives the rotating table to rotate in the vertical direction, thereby driving the guide pipe to rotate and changing the orientation of the guide pipe. The second driving component drives the guide pipe to rotate in the horizontal direction on the rotating table to adjust the tilt angle of the guide pipe. This allows for adjustment of the position of the aggregate discharged from the guide pipe according to the feed end of the receiving equipment. It solves the technical problem that existing feeding devices cannot adjust the height and orientation of the aggregate discharge, resulting in the technical effect of being able to adjust the position of the aggregate discharge, meeting the feeding needs of different models of equipment. Moreover, the adjustment operation is simple and convenient to use. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a concrete aggregate feeding device for feeding concrete aggregate into the input end of equipment such as a mixer during the concrete production process.

[0023] Please refer to Figure 1 and Figure 2 The concrete aggregate feeding device includes a base 1, on which a rotating platform 2 rotatable in a vertical direction and a first driving component pulsatingly connected to the rotating platform 2 are provided. The rotating platform 2 has a guide pipe 3 rotatable in a horizontal direction and a second driving component pulsatingly connected to the guide pipe 3. When the rotating platform 2 rotates under the drive of the first driving component, it drives the guide pipe 3 to rotate in a vertical direction, thereby changing the orientation of the guide pipe 3. The tilt angle of the guide pipe 3 can be adjusted by driving the guide pipe 3 to rotate through the second driving component. A rotatable conveying rod 31 is provided inside the guide pipe 3, and a third driving component pulsatingly connected to the conveying rod 31 is provided on the guide pipe 3. The feeding rod 31 is provided with a spiral blade 32. The two ends of the feed pipe 3 are respectively provided with a feed pipe 33 and a discharge pipe 34. The feed pipe 33 has a first hemispherical shell 35 at the end away from the feed pipe 3. The base 1 is also provided with a feed hopper 4. The bottom of the feed hopper 4 is provided with a conveying pipe 41, and the end of the conveying pipe 41 away from the feed hopper 4 is provided with a second hemispherical shell 42 that cooperates with the first hemispherical shell 35. The feed pipe 3 and the feed hopper 4 are movably connected through the cooperation of the first hemispherical shell 35 and the second hemispherical shell 42, so that the feed pipe 3 can rotate in any direction relative to the feed hopper 4, and ensure that the feed pipe 3 remains in communication with the feed hopper 4 during the rotation.

[0024] Specifically, the operation steps for adjusting the discharge position of the concrete aggregate feeding device provided in this embodiment are as follows: When it is necessary to adjust the orientation of the guide pipe 3, the first driving component is activated to drive the rotating table 2 to rotate in the vertical direction, thereby causing the guide pipe 3 to rotate in the vertical direction and thus changing the orientation of the guide pipe 3; when it is necessary to adjust the tilt angle of the guide pipe 3, the second driving component is activated to drive the guide pipe 3 to rotate in the horizontal direction on the rotating table 2, thereby changing the tilt angle of the guide pipe 3. That is, the concrete aggregate feeding device provided in this embodiment can adjust the orientation and tilt angle of the guide pipe 3 through the first driving component and the second driving component, so as to adjust the discharge position of the guide pipe 3 according to the feeding end of the receiving aggregate equipment, thereby meeting the feeding needs of different models of equipment, and the adjustment operation is simple and convenient to use.

[0025] like Figure 2 and Figure 3As shown, the base 1 is provided with a receiving groove 11, and the rotating platform 2 is rotatably disposed within the receiving groove 11. Providing the receiving groove 11 on the base 1 for the rotating platform 2 to be installed allows the rotating platform 2 to remain stable on the base 1, thereby improving the structural stability of the concrete aggregate feeding device.

[0026] In detail, the base 1 has a first through hole communicating with the receiving groove 11, the rotating platform 2 has a connecting shaft 21 passing through the first through hole, and the first driving component includes a first motor 12. The connecting shaft 21 cooperates with the output end of the first motor 12. The rotating platform 2 is configured such that the connecting shaft 21 passes through the first through hole and cooperates with the output end of the first motor 12, so that the rotating platform 2 can rotate under the drive of the first motor 12 to adjust the orientation of the guide tube 3.

[0027] Please combine Figure 3 and Figure 4 The rotating platform 2 is provided with a support 22, and the support 22 is provided with a detachable pressure block 23. The first hemispherical shell 35 is provided with a mounting shaft 36. The support 22 and the pressure block 23 form a mounting hole that mates with the mounting shaft 36. By setting the detachable pressure block 23 on the support 22, and by using the support 22 and the pressure block 23 to form a mounting hole that mates with the mounting shaft 36, the guide tube 3 is installed onto the rotating platform 2, and the guide tube 3 and the rotating platform 2 are rotatably connected. When installing the guide tube 3 onto the rotating platform 2, the mounting shaft 36 is first placed on the support 22, and then the pressure block 23 is installed onto the support 22 and fixed with bolts. This ensures that the position of the guide tube 3 on the rotating platform 2 remains stable and that the fit between the guide tube 3 and the rotating platform 2 is reliable.

[0028] In this embodiment, the first hemispherical shell 35 is provided with a detachable connecting ring 5. The connecting ring 5 and the first hemispherical shell 35 form a spherical groove for accommodating the second hemispherical shell 42, and the connecting ring 5 is provided with a clearance hole 52 to avoid the mounting shaft 36. After the second hemispherical shell 42 is placed into the first hemispherical shell 35, the connecting ring 5 is installed on the first hemispherical shell 35 so that the second hemispherical shell 42 is held in the spherical groove formed by the connecting ring 5 and the first hemispherical shell 35. The clearance hole 52 on the connecting ring 5 avoids the mounting shaft 36, preventing the second hemispherical shell 42 from separating from the first hemispherical shell 35 when the guide pipe 3 rotates, thus ensuring a secure connection between the feed hopper 4 and the guide pipe 3.

[0029] Please refer to Figure 1 and Figure 4The connecting ring 5 includes two semi-ring bodies 51, each with a first through hole 53. The first hemispherical shell 35 has a second through hole aligned with the first through hole 53. The connecting ring 5 is configured as an annulus formed by the two semi-ring bodies 51, so as to facilitate the installation of the connecting ring 5 onto the first hemispherical shell 35 and its fit against the second hemispherical shell 42. After the semi-ring body 51 is placed on the first hemispherical shell 35, the first through hole 53 and the second through hole are aligned. The semi-ring body 51 can be fixed to the first hemispherical shell 35 by passing bolts through the first through hole 53 and the second through hole in sequence.

[0030] like Figure 2 As shown, the second driving component includes a cylinder 24 and a piston rod 25 disposed at the output end of the cylinder 24. The cylinder 24 is rotatably connected to the rotating table 2, and the piston rod 25 is rotatably connected to the guide tube 3. The cylinder 24 drives the piston rod 25 to extend or retract, thereby driving the guide tube 3 to rotate on the rotating table 2. This allows for adjustment of the tilt angle of the guide tube 3. Furthermore, the cylinder 24 controls the stroke of the piston rod 25 to precisely control the rotation angle of the guide tube 3, ensuring that the guide tube 3 can be adjusted to the target position for feeding operations.

[0031] like Figure 2 and Figure 3 As shown, the third driving component includes a second motor 37. The guide pipe 3 has a second through hole through which the conveying rod 31 passes, and the conveying rod 31 cooperates with the output end of the second motor 37. By using the second motor 37 to drive the conveying rod 31 to rotate, the spiral blade 32 can be driven to rotate, thereby conveying the aggregate entering the guide pipe 3 along the axial direction of the guide pipe 3, so as to transport the aggregate from the feed pipe 33 to the discharge pipe 34, and then discharge the aggregate from the discharge pipe 34 into the feed end of the receiving equipment, thereby realizing feeding.

[0032] Please refer to Figure 1 and Figure 2 The base 1 is provided with a plurality of legs 13 spaced apart along its axial direction, and each leg 13 is provided with a caster wheel 14. The plurality of legs 13 on the base 1 support the base 1, and the caster wheel 14 on each leg 13 allows the base 1 to move easily on the ground, so as to facilitate the handling of the concrete aggregate feeding device.

[0033] 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 this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
