Description

Technical Field

[0001] The utility model relates to the field of early-strength frost-resistant recycled concrete production equipment, and specifically discloses a proportioning device for early-strength frost-resistant recycled concrete. Background Art

[0002] Different materials need to be added during the production process of early-strength frost-resistant recycled concrete. Therefore, before mixing, a proportioning device is needed to automatically proportion the materials according to the proportion. The hopper and belt conveyor in the existing proportioning equipment are installed on the frame in a separate fixed manner. The materials will accumulate in the belt conveyor and the hopper, and the material feed amount cannot be directly measured, resulting in the proportioning equipment being unable to accurately weigh and proportion the materials. Utility Model Content

[0003] In view of the above-mentioned defects or shortcomings in the prior art, the present application aims to provide a mixing device for early-strength frost-resistant recycled concrete, comprising a first vertical support, a first horizontal support arranged on the top of the first vertical support, a second vertical support arranged on the top of the first horizontal support, and a second horizontal support arranged inside the second vertical support, a U-shaped frame is arranged on the top of the second horizontal support, a supporting mechanism is movably sleeved inside the U-shaped frame, a hopper is arranged on the outside of the supporting mechanism, a limiting mechanism is arranged on the outside of the hopper, a mounting frame is fixedly installed on the bottom of the limiting mechanism, and a belt conveyor located below the hopper is fixedly installed on the top of the mounting frame.

[0004] Preferably, the limiting mechanism includes a first limiting frame and a second limiting frame arranged on the outside of the hopper, and a first screw rod and a second screw rod arranged on the top of the mounting frame and respectively inserted into the first limiting frame and the second limiting frame. The top ends of the first screw rod and the second screw rod extending out of the outside of the first limiting frame and the second limiting frame are both threadedly sleeved with nuts on the outside.

[0005] Preferably, the support mechanism includes a limit block arranged outside the hopper, a limit rod movably sleeved inside the U-shaped frame is arranged at the bottom of the limit block, and a fixing pin is fixedly sleeved inside the bottom end of the limit rod extending to the inside of the U-shaped frame.

[0006] Preferably, a pressure sensor located below the limit block is fixedly mounted on the outer side of the U-shaped frame, and the pressure sensors are distributed on the outer side of the hopper in groups of four.

[0007] Preferably, a support plate is provided on the inner side of the hopper close to the limit block.

[0008] Beneficial effects:

[0009] 1. The early-strength frost-resistant recycled concrete proportioning equipment uses a first limit frame, a second limit frame, a first screw rod, a second screw rod, a nut and a mounting frame to fix the belt conveyor under the hopper. At the same time, the limit block, the limit rod and the U-shaped frame are used together to enable the hopper and the belt conveyor to move synchronously along the axial direction of the limit rod, and then the material feed amount can be calculated by the change in the force of the limit block acting on the pressure sensor. This structure allows the hopper to be set separately, and the material feed amount of the proportioning equipment can be accurately calculated by averaging the pressure change differences measured by four pressure sensors.

[0010] 2. The early-strength frost-resistant recycled concrete proportioning equipment can provide position-limited support for the bottom hopper by arranging a support plate on the inner side of the hopper, so that the hopper is not easily deformed by force, and ensures that the hopper can be stably position-limited and supported by the cooperation of the U-shaped frame, the limit block and the limit rod.

DETAILED DESCRIPTION

[0018] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0019] The accompanying drawings in the embodiments of the present invention: different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0020] See also Figure 1-5 The mixing equipment of early-strength frost-resistant recycled concrete includes a first vertical support 1, a first horizontal support 2 arranged on the top of the first vertical support 1, a second vertical support 3 arranged on the top of the first horizontal support 2 and a second horizontal support 4 arranged inside the second vertical support 3, a U-shaped frame 5 is arranged on the top of the second horizontal support 4, a supporting mechanism 6 is movably sleeved inside the U-shaped frame 5, a hopper 7 is arranged on the outside of the supporting mechanism 6, two or more hoppers 7 are used as a group, so that the mixing setting can mix multiple materials at the same time, a limiting mechanism 8 is arranged on the outside of the hopper 7, a mounting frame 9 is fixedly installed on the bottom of the limiting mechanism 8, and a belt conveyor 10 located below the hopper 7 is fixedly installed on the top of the mounting frame 9.

[0021] Among them, the limiting mechanism 8 includes a first limiting frame 81 and a second limiting frame 82 arranged on the outside of the hopper 7, and a first screw rod 83 and a second screw rod 84 arranged on the top of the mounting frame 9 and respectively mounted inside the first limiting frame 81 and the second limiting frame 82. The first screw rod 83 and the second screw rod 84 extend out of the first limiting frame 81 and the second limiting frame 82, and the outer sides of the top ends are both threaded with nuts 85. Through the cooperation of the first limiting frame 81 and the second limiting frame 82, the mounting frame 9 can be supported while ensuring that the belt conveyor 10 on the mounting frame 9 can be stably fixed and installed under the hopper 7, thereby making it difficult for the belt conveyor 10 to shake during the driving process.

[0022] Among them, the supporting mechanism 6 includes a limit block 61 arranged on the outside of the hopper 7, and a limit rod 62 movably sleeved inside the U-shaped frame 5 is arranged at the bottom of the limit block 61. The limit rod 62 extends to the bottom end of the inner side of the U-shaped frame 5 and is fixedly sleeved with a fixing pin 63. The fixing pin 63 can limit the limit rod 62 while ensuring that the limit rod 62 can move a certain distance inside the U-shaped frame 5, so that the force generated by the hopper 7 can act on the top of the pressure sensor 11 through the limit block 61.

[0023] Among them, a pressure sensor 11 located below the limit block 61 is fixedly installed on the outer side of the U-shaped frame 5, and four pressure sensors 11 are distributed on the outer side of the hopper 7 in a group. The pressure sensor 11 can detect the pressure of the hopper 7 through the limit block 61, so that when the material inside the hopper 7 is transported by the belt conveyor 10, the pressure detected by the pressure sensor 11 will change, and then the material feed amount can be calculated according to the pressure change. At the same time, the four pressure sensors 11 can be used to take the average value to ensure the accuracy of the pressure change, so that the proportioning equipment can accurately control the drive of the belt conveyor 10, so that the proportioning equipment can accurately weigh and proportion the materials.

[0024] Among them, a support plate 12 is provided on the inner side of the hopper 7 near the limit block 61. The support plate 12 can provide limit support to the inner side of the hopper 7 while increasing the structural strength of the hopper 7, so that when the hopper 7 is supported by the limit block 61, its supporting part is not easily deformed.

[0025] When the proportioning equipment is working, the material inside the hopper 7 is transported by driving the belt conveyor 10, and the pressure of the hopper 7 on the limit block 61 is detected by the pressure sensor 11. As the belt conveyor 10 continues to convey, the material inside the hopper 7 gradually decreases. The reduction in the material inside the hopper 7 can be calculated based on the pressure change measured by the pressure sensor 11, and then the average value is calculated based on the measurement results of the four pressure sensors 11 to calculate the feed amount of the material, thereby controlling the drive of the belt conveyor 10 to ensure that the proportioning equipment can accurately weigh and proportion the material according to the set proportion of the material.
