Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a mixing device for stable material output. Background Technology

[0002] In the field of mixture testing (sand, gravel, coarse and fine aggregates, and soil), mixture mixing is a crucial step in the testing process. The purpose of thorough mixing is to ensure material homogeneity, improve the accuracy of test results, and guarantee the repeatability and comparability of test data, thus better reflecting the true engineering performance of the materials.

[0003] In traditional testing methods, the mixing process mainly relies on manual operation. Manual mixing is inefficient, cannot meet the needs of large-scale testing, and may result in insufficient mixing of the binder due to human factors. Therefore, it is necessary to design a mixing device with stable output. Utility Model Content

[0004] The purpose of this invention is to provide a mixing device with stable output to solve the problem of insufficient mixing in existing mixing devices.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mixing device for stable material output, including a base frame and a vibrating motor;

[0006] A bracket is fixed to one side of the top of the base frame;

[0007] A hopper is provided on the inner side of the support frame;

[0008] The hopper is equipped with a stirring structure, which includes a stirring shaft inside the hopper and blades fixed on the outer wall of the stirring shaft. The stirring structure also includes a discharge pipe rotatably connected to the bottom of the hopper. A second bevel gear is fixed on the outer wall of the top of the discharge pipe. A first bevel gear is meshed with one side of the second bevel gear. The stirring structure also includes a drive motor fixedly installed on the top of the base frame near the first bevel gear. Connecting rods are evenly fixed on the outer wall of the bottom of the stirring shaft.

[0009] Furthermore, a collection box is provided below the base frame, and a pressure sensor is fixed on the inner wall of the bottom of the collection box.

[0010] Furthermore, a movable structure is fixed to the top of the support, a buffer structure is provided on the outer wall of the top of the hopper, and the vibration motor is fixed to the outer wall of the hopper above the buffer structure.

[0011] Furthermore, the buffer structure includes a support plate, dampers, springs, and connecting plates. The support plate is fixed to the inner wall of the bracket. Dampers are uniformly fixed to the top of the support plate. Springs are provided on the outer sides of the dampers. Connecting plates are fixed to the top of the springs.

[0012] Furthermore, the dampers and springs are evenly distributed at the top of the support plate, and the inner wall of the connecting plate is fixedly connected to the outer wall of the hopper.

[0013] Furthermore, the movable structure includes a cover, a connecting sleeve, and a lead screw. The lead screw is fixedly installed on the top of the bracket, and the connecting sleeve is threaded onto the outer wall of the lead screw. The cover is fixed to the bottom end of the connecting sleeve.

[0014] Furthermore, the central axis of the lead screw and the central axis of the hopper are collinear.

[0015] Furthermore, the output end of the drive motor is fixedly connected to one side of the first bevel gear, the end of the connecting rod away from the stirring shaft is fixedly connected to the inner wall of the discharge pipe, and a pneumatic valve is fixedly installed at the bottom of the discharge pipe.

[0016] Furthermore, a microcontroller is installed inside the pressure sensor, and the output end of the pressure sensor and the input end of the pneumatic valve inside the discharge pipe are electrically connected through the microcontroller.

[0017] The present invention provides a mixing device for stable material output, the advantages of which are:

[0018] By incorporating a stirring structure and a vibrating motor, the vibration of the motor helps the material vibrate and tumble inside the hopper. The rotation of the stirring shaft and blades helps the material to be fully and evenly mixed inside the hopper, thus enabling the device to efficiently mix materials and improving the working efficiency of the mixing device with stable output.

[0019] By incorporating a buffer structure, the damper and spring work together to absorb the impact force generated by the vibrating motor on the hopper during vibration, reducing the transmission of equipment vibration to the base, extending service life, and enabling the device to buffer the equipment, thus improving the stability of the mixing device with stable output during use.

[0020] By incorporating a movable structure, the connecting sleeve and the screw threaded connection allow the connecting sleeve to move up and down on the outside of the screw through rotation of the silo cover. This enables the silo cover to move closer to or further away from the silo, opening and closing the cover and facilitating quick installation and removal. This design allows the device to easily close and open the silo cover, improving the convenience of using the stable discharge mixing device. Attached Figure Description

[0028] 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.

[0029] Please see Figures 1-6 The present invention provides a mixing device for stable material output, comprising a base frame 1 and a vibration motor 5.

[0030] Reference Figure 1 , Figure 2 and Figures 4-6A support 2 is fixed to one side of the top of the base frame 1. A hopper 3 is arranged inside the support 2. A stirring structure 7 is arranged inside the hopper 3. The stirring structure 7 includes a stirring shaft 71 arranged inside the hopper 3. Blades 72 are fixed on the outer wall of the stirring shaft 71. The stirring structure 7 also includes a discharge pipe 76 rotatably connected to the bottom of the hopper 3. A second bevel gear 75 is fixed on the outer wall of the top of the discharge pipe 76. A first bevel gear 73 is meshed with one side of the second bevel gear 75. The stirring structure 7 also includes a fixedly installed part near the top of the base frame 1. A drive motor 74 is located on one side of the gear 73. Connecting rods 77 are evenly fixed on the outer wall of the bottom of the stirring shaft 71. The output end of the drive motor 74 is fixedly connected to one side of the first bevel gear 73. The end of the connecting rod 77 away from the stirring shaft 71 is fixedly connected to the inner wall of the discharge pipe 76. A pneumatic valve is fixedly installed at the bottom of the discharge pipe 76. A collection box 8 is set below the base frame 1. A pressure sensor 9 is fixedly installed on the inner wall of the bottom of the collection box 8. A microcontroller is installed inside the pressure sensor 9. The output end of the pressure sensor 9 and the input end of the pneumatic valve inside the discharge pipe 76 are electrically connected through the microcontroller.

[0031] When an external power source is connected, the drive motor 74 is started. The drive motor 74 drives the first bevel gear 73 to rotate. The first bevel gear 73 drives the second bevel gear 75, which in turn drives the discharge pipe 76 to rotate. When the discharge pipe 76 rotates, it drives the stirring shaft 71 to rotate through the connecting rod 77. The stirring shaft 71 drives the blades 72 to rotate, shearing the material. After mixing, the pneumatic valve inside the discharge pipe 76 is opened, and the material falls into the collection box 8 through the discharge pipe 76. The discharge amount can be controlled by the pressure sensor 9 at the bottom of the collection box 8, thereby controlling the discharge amount to be approximately equal and improving the accuracy of the test results.

[0032] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The top of the support 2 is fixed with a movable structure 6, which includes a hopper cover 61, a connecting sleeve 62 and a screw rod 63. The screw rod 63 is fixedly installed on the top of the support 2. The connecting sleeve 62 is threaded onto the outer wall of the screw rod 63. The hopper cover 61 is fixed at the bottom end of the connecting sleeve 62. The central axis of the screw rod 63 and the central axis of the hopper 3 are collinear.

[0033] Rotating the hopper cover 61 causes the connecting sleeve 62 to rotate outside the lead screw 63. Since the connecting sleeve 62 and the lead screw 63 are threadedly connected, the connecting sleeve 62 moves up and down along the lead screw 63 when it rotates, thereby driving the hopper cover 61 to rise and fall, adjusting the distance between the hopper cover 61 and the hopper 3. When it is necessary to add material, the hopper cover 61 is moved upward. When it is necessary to seal the top of the hopper 3, the hopper cover 61 is moved downward so that the hopper cover 61 and the hopper 3 fit tightly together.

[0034] Reference Figures 1-6 A buffer structure 4 is provided on the outer wall of the top of the hopper 3. The buffer structure 4 includes a support plate 41, a damper 42, a spring 43 and a connecting plate 44. The support plate 41 is fixed to the inner wall of the bracket 2. The damper 42 is evenly fixed on the top of the support plate 41. The spring 43 is provided on the outer side of the damper 42. The connecting plate 44 is fixed on the top of the spring 43. The damper 42 and the spring 43 are evenly distributed on the top of the support plate 41. The inner wall of the connecting plate 44 is fixedly connected to the outer wall of the hopper 3. The vibration motor 5 is fixed on the outer wall of the hopper 3 above the buffer structure 4.

[0035] When the external power supply is connected, the vibration motor 5 is started. When the vibration motor 5 is running, the vibration energy of the hopper 3 is transmitted to the spring 43 and the damper 42 through the connecting plate 44. The spring 43 provides elastic buffering, and the damper 42 can guide the spring 43 to ensure that the hopper 3 remains stable when subjected to vibration.

[0036] 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.
