Description

Technical Field

[0001] The present invention relates to the technical field of mixer feeding, and more particularly to an automatic mixer feeding device. Background Art

[0002] In today's grand scenes of construction and industrial production, mixers are undoubtedly one of the most important equipment. In the field of construction, whether it is the rise of high-rise buildings, the laying of roads and bridges, or the construction of various infrastructures, mixers play an indispensable role. From the mixing of concrete to the mixing of various special materials, the efficient operation of the mixer is directly related to the progress and quality of the project. The traditional way of feeding mixers mainly relies on manual handling of materials or hoisting of materials to the top of the mixer for feeding.

[0003] After searching, a Chinese patent with announcement number CN111571807A discloses an automatic and efficient feeding device for a mixer. In view of the problem in its cited documents that the mixer feeding work is facilitated by driving the bucket car through a lifting device, and the laborious work of manual feeding is reduced, but the feeding method of the mixer is not stable enough and the feeding efficiency is not high, the automatic and efficient feeding device is provided with a hydraulic cylinder and an aggregate frame. The hydraulic cylinder can lift the aggregate frame filled with concrete raw materials, and the cylinder drives the push plate to move, so that the concrete raw materials in the aggregate frame are quickly pushed into the hopper for mixing by the concrete mixer. This concrete mixer feeding method is fast and stable, avoids the inefficient feeding operation of manpower, and makes the mixer feeding effect better and the feeding efficiency higher.

[0004] When the mixer is fed automatically and efficiently, the materials need to be transported to the top of the mixer and then poured into the mixer. On the one hand, the feeding process requires a hoisting device to lift the materials above the mixer, which is labor-intensive. The feeding process lacks stability and continuity, and it is difficult to accurately control the feeding speed. It cannot perfectly match the actual working rhythm of the mixer, which often leads to interruptions in material supply, greatly hindering the improvement of production efficiency. On the other hand, it is difficult to ensure the stability and accuracy of the feeding speed, and it cannot be flexibly adjusted according to the actual working needs of the mixer, which easily leads to untimely material supply and affects production progress. At the same time, during the feeding process, When materials fall into the mixer from a height, they tend to scatter everywhere, especially some small debris and dust, which not only seriously pollutes the working environment and poses a huge threat to the health of operators, but also causes a large amount of material waste, which runs counter to the current concept of environmental protection and sustainable development, affects the health of operators, and also causes material waste. In addition, traditional mixer feeding equipment is usually large in size and complex in structure, which is not easy to move and difficult to adapt to the use requirements of different scenarios. This makes it difficult to switch between different work sites and adapt to the needs of different models of mixers, which greatly limits the flexibility and adaptability of production.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] As attached Figure 1-8 The automatic feeding device for a mixer shown comprises a hopper 1, a supporting bottom plate 2 is fixedly connected to the bottom of the hopper 1, and a feeding mechanism is arranged on one side of the hopper 1; The feeding mechanism includes two fixed side plates 3, which are respectively fixed on both sides of the inner wall of the hopper 1, and a support plate 4 is fixedly connected to one side of the fixed side plates 3. A motor 5 is fixedly installed on one side of one of the fixed side plates 3, and a first rotating shaft 6 is fixedly connected to the output end of the motor 5. A second rotating shaft 7 is arranged on one side of the first rotating shaft 6. A conveyor belt 8 is transmission-connected between the first rotating shaft 6 and the second rotating shaft 7. Rotating blocks 9 are fixedly connected to both ends of the second rotating shaft 7, and a digging plate 10 is fixedly installed on the outer side of the conveyor belt 8; A hydraulic rod 11 is fixedly installed on one side of the hopper 1, and a push plate 12 is fixedly connected to one end of the hydraulic rod 11. A fixed slide plate 13 is arranged at the bottom of the conveyor belt 8, and a protective side plate 14 is fixedly connected between the fixed slide plate 13 and the fixed side plate 3. One side of the fixed slide plate 13 and the protective side plate 14 are fixedly connected to one side of the inner wall of the hopper 1, and a material unloading dust removal mechanism is arranged on one side of the conveyor belt 8.

[0027] It can be seen that in the above technical solution, the first rotating shaft 6 at its output end is driven to rotate by the motor 5. At the same time, since the first rotating shaft 6 and the second rotating shaft 7 are connected by a conveyor belt 8, the conveyor belt 8 moves to drive the multiple digging plates 10 evenly distributed on its outside to move, so that the digging plates 10 dig up the materials inside the hopper 1, and drive the materials to move to the top of the funnel hopper 16 through the digging plates 10. The digging plates 10 are rotated by the conveyor belt 8, so that the device is more consistent when feeding, ensuring the continuous supply of materials, thereby improving production efficiency, and at the same time, it can automatically lift the materials from the lower hopper to the top of the high mixer, reducing labor intensity.

[0028] As attached Figure 1 , 2 As shown in , 3, 4, 5, and 8, the unloading dust removal mechanism includes a fixed cross bar 15, which is fixed to one side of the support plate 4. The number of the support plates 4 is set to two, and a hopper 16 is installed between the two support plates 4. A fixed rod 17 is fixedly connected between the hopper 16 and the support plate 4. A dust box 21 is set at the bottom of the fixed cross bar 15, and a connecting rod 22 is fixedly connected between the fixed cross bar 15 and the dust box 21, so that the hopper 16 is located at the bottom of one side of the conveyor belt 8, while ensuring the installation and fixing effect of the hopper 16.

[0029] As attached Figure 1 , 2 As shown in , 3, 4, 5, and 8, a fixed plate 23 is fixedly connected to one side of the dust box 21, the dust suction groove 24 is connected to the dust box 21, the fixed plate 23 is arranged on the outside of the hopper 16, and a dust suction groove 24 is opened on one side of the fixed plate 23. An exhaust fan 25 is fixedly installed on one side of the dust box 21, so that dust and fine materials in the feeding process are sucked into the dust box 21 through the dust suction groove 24, and then the material dust is isolated through the dustproof net 26, and the air is discharged through the exhaust fan 25.

[0030] It can be seen that in the above technical solution, the exhaust fan 25 draws out the air inside the dust box 21, so that the dust box 21 generates suction, so that the dust suction groove 24 on the surface of the fixed plate 23 generates suction, and then the fine debris and material dust in the material falling from the hopper 16 enter the dust box 21 through the dust suction groove 24, and then the material dust is isolated through the dustproof net 26, and the air is discharged through the exhaust fan 25, and the isolated material dust and fine debris are discharged into the mixer through the dust exhaust pipe 27, which solves the problem of dust flying during the feeding process of the mixer, avoids the harm of dust to the working environment and the health of operators, and realizes the recycling of materials and reduces the waste of materials.

[0031] As attached Figure 8As shown, a dustproof net 26 is fixedly installed on the inner wall of the dust collecting box 21, a dust exhaust pipe 27 is fixedly connected to the bottom of the dust collecting box 21, and an electromagnetic valve 28 is fixedly installed inside the dust exhaust pipe 27, which is convenient for collecting fine materials and their dust and avoiding the loss of materials during the feeding process. The isolated material dust and fine debris are discharged into the mixer through the dust exhaust pipe 27, avoiding dust flying and avoiding the waste of materials.

[0032] As attached Figure 1 , 2 As shown in , 3, 4, and 8, a support rod 18 is fixedly connected to the bottom of the support plate 4, a support column 19 is fixedly connected to the bottom of the support base plate 2, and moving wheels 20 are fixedly installed at the bottom of the support rod 18 and the support column 19, which improves the stability of the device and ensures the mobility of the device, making it easy to move the device to different mixers for use.

[0033] It can be seen that in the above technical solution, the setting of the support column 19 and the support rod 18 provides stable support for the entire device. During the operation of the device, it can effectively resist the vibration of the motor and the weight of the material, ensure the smooth operation of the device, and improve the reliability of the equipment. The moving wheels 20 make the device easy to move, and it can be easily moved to different mixers for use, adapting to different work sites and production needs, greatly improving the maneuverability and flexibility of the device.

[0034] As attached Figure 1 , 2 As shown in , 3, 4, 7, and 8, the number of digging plates 10 is set to be multiple, and the multiple digging plates 10 are evenly distributed on the outside of the conveyor belt 8, so that the material can be continuously transported to the hopper 16 through the digging plates 10 for feeding, thereby ensuring the material transportation effect.

[0035] As attached Figure 3 , 4 As shown in , 7, the first rotating shaft 6 and the second rotating shaft 7 are both rotatably connected to the fixed side plate 3, and the rotating block 9 is rotatably connected to the inner wall of the hopper 1, which facilitates the rotation of the first rotating shaft 6 and the second rotating shaft 7, thereby allowing the conveyor belt 8 to move continuously.

[0036] As attached Figure 1 , 2 As shown in , 3, 4, 6, and 8, the motor 5 is fixedly mounted on the top of the support plate 4, one end of the hydraulic rod 11 passes through the hopper 1 and extends to one side of the hopper 1, and the push plate 12 is slidably connected to the inner wall of the hopper 1, so that the material on one side of the hopper 1 is pushed into a position close to the digging plate 10, so that the material is filled onto the digging plate 10; It can be seen that in the above technical solution, the push plate 12 can be driven to move by the hydraulic rod 11 on one side of the hopper 1, thereby avoiding the situation where the materials on one side of the digging plate 10 inside the hopper 1 are transported and left empty, so that the materials can always be dug up by the digging plate 10 for transportation. At the same time, the push plate 12 is driven to move by the hydraulic rod 11, so that the inner wall of the hopper 1 can be cleaned to avoid excessive raw materials remaining inside the hopper 1.

[0037] Working principle of the present invention: During use, the automatic feeding device of the mixer provided by the present invention starts the motor 5 installed on the top of the support plate 4, so that the motor 5 drives the first rotating shaft 6 at its output end to rotate. At the same time, since the first rotating shaft 6 and the second rotating shaft 7 are connected by a conveyor belt 8, the conveyor belt 8 moves to drive multiple digging plates 10 evenly distributed on its outer side to move, so that the digging plate 10 digs up the material inside the hopper 1, drives the material to move to the top of the hopper 16 through the digging plate 10, and rotates the digging plate 10 through the conveyor belt 8, so that the material on the digging plate 10 falls into the hopper 16 due to gravity, so that the material enters the mixer through the hopper 16, completing the automatic feeding of the automatic mixer. At the same time, the hydraulic rod 11 drives the push plate 12 to move, so that the material is pushed onto the digging plate 10 through the push plate 12, so as to avoid the material near the digging plate 10. Can not be automatically loaded, so that the digging plate 10 can continuously transport the material, which is convenient for the material to be automatically lifted to the top of the mixer, which is convenient for the feeding of the mixer; During the feeding process, when the material falls into the mixer through the hopper 16, the exhaust fan 25 on one side of the dust box 21 is started, so that the exhaust fan 25 draws out the air inside the dust box 21, so that the dust box 21 generates suction, so that the dust suction groove 24 on the surface of the fixed plate 23 generates suction, and then the fine debris and material dust in the material falling from the hopper 16 enter the dust box 21 through the dust suction groove 24, and then the material dust is isolated through the dustproof net 26, and the air is discharged through the exhaust fan 25, and the isolated material dust and fine debris are discharged into the mixer through the dust exhaust pipe 27, so as to avoid dust flying and material waste. At the same time, the support column 19 installed at the bottom of the support base plate 2 and the support rod 18 installed at the bottom of the motor 5 are used to improve the stability of the overall device, and at the same time, it is convenient to improve the maneuverability of the device and facilitate the device to be moved to different mixers for use.
