It primarily consists of a mixing drum, loading and unloading mechanisms, a water supply system, a prime mover, a transmission mechanism, a frame, and a support device. Based on their operating characteristics, they are classified into intermittent and continuous types; based on their mixing principle, they are classified into free-fall and forced types; based on their installation method, they are classified into fixed and mobile types; based on their discharge method, they are classified into tilting and non-tilting types; and based on their mixing drum structure, they are classified into pear-type, drum-type, double-cone, disc-type vertical shaft, and circular-trough horizontal shaft types. Currently, most concrete mixers on the market have open inlets, which generate a large amount of concrete dust during the mixing process. This dust is released through the inlet, affecting construction hygiene, endangering the health of construction workers, and polluting the environment.

[0004] After extensive searching, it was found that the patent document with application number CN202220824965.2 discloses a dust-proof device for a concrete mixer. However, there are still problems that need to be improved in the actual use of the above patent. The most obvious one is the method of using a motor and a hydraulic cylinder to drive the sealing cover to seal the feed hopper for dust prevention, which has a complex structure and high maintenance and use costs.

[0005] To this end, we proposed a concrete mixer feeding dust prevention device to solve the above drawbacks. Utility Model Content

[0025] Please refer to Figure 1-4 The concrete mixer feeding dust prevention device includes a feed hopper 1, a feeding port 2 is provided on the top surface of the feed hopper 1, and a receiving groove 13 is provided on the side wall of the feeding port 2. The internal rotation of the receiving groove 13 is connected to a half gear 4, and one end of the half gear 4 is installed with a dustproof plate 3, and the dustproof plate 3 is used in conjunction with the receiving groove 13 and the feeding port 2. A handle 5 is installed on the top surface of the feed hopper, and one end of the handle 5 is installed with a gear 6, and the gear 6 is engaged with the half gear 4. A water spray pipe 10 is hoisted on the inner top surface of the feed hopper 1, and a spray head 11 is detachably installed on the surface of the water spray pipe 10. A water pump 7 is fixedly installed on the top surface of the feed hopper 1, and the water outlet and water inlet ends of the water pump 7 are respectively installed with a water outlet pipe 9 and a water inlet pipe 8. The other end of the water inlet pipe 8 is connected to the municipal water pipe, and the other end of the water outlet pipe 9 is connected to the water spray pipe 10.

[0026] When in use, rotating the handle 5 drives the gear 6 to rotate, and the rotation of the gear 6 drives the half gear 4 meshing with it to rotate, and the rotation of the half gear 4 drives the dustproof plate 3 to rotate and seal the feeding port 2 to achieve the dust-proof effect. Conversely, rotating the handle 5 in the opposite direction can make the dustproof plate 3 rotate in the opposite direction and be stored in the storage groove 13. At this time, the dustproof plate 3 no longer seals the feeding port 2, so that feeding can be carried out. It is highly practical, and has a simple structure, is stable and reliable, and has low maintenance and use costs. The water inlet pipe 8 is connected to the water source, and the water pump 7 can pump water into the water spray pipe 10, and then spray it out from several spray heads 11, which can suppress the dust-laden air in the feed hopper 1. It is highly practical and worthy of promotion.

[0027] In this embodiment, a control switch 12 is fixedly mounted on the outer wall of the feed hopper 1 , and the control switch 12 is electrically connected to the water pump 7 via a wire.

[0028] Specifically, it is a common circuit connection structure, which is commonplace for those skilled in the art and will not be described in detail here.

[0029] In this embodiment, the volume of the storage groove 13 is greater than the volume of the dustproof plate 3 .

[0030] Specifically, the dustproof plate 3 can be completely received in the receiving groove 13 , and the feeding port 2 can be completely opened without being blocked by the dustproof plate 3 .

[0031] In this embodiment, the diameter of the feeding port 2 is smaller than the diameter of the dustproof plate 3 .

[0032] Specifically, the dustproof plate 3 has a better sealing and dustproof effect on the feeding port 2.

[0033] In this embodiment, a plurality of spray heads 11 are provided, and the plurality of spray heads 11 are distributed on the surface of the water spray pipe 10 in a circular array.

[0034] Specifically, the dust suppression effect and efficiency of dust-laden air are improved.

[0035] In this embodiment, the thickness of the dustproof plate 3 is smaller than the thickness of the feed hopper 1 .

[0036] Specifically, the dustproof plate 3 and the receiving groove 13 can be arranged inside the feed hopper 1 .

[0037] In this embodiment: the control switch 12 is an existing structure, and the control circuit can be implemented by simple programming by technicians in this field. It is common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection are not described in detail.

[0038] Working principle: When in use, rotating the handle 5 drives the gear 6 to rotate, and the rotation of the gear 6 drives the half gear 4 meshing with it to rotate, and the rotation of the half gear 4 drives the dustproof plate 3 to rotate and seal the feeding port 2 to achieve the dust-proof effect. Conversely, rotating the handle 5 in the opposite direction can make the dustproof plate 3 rotate in the opposite direction and be stored in the storage groove 13. At this time, the dustproof plate 3 no longer seals the feeding port 2, so that feeding can be carried out. It is highly practical, has a simple structure, is stable and reliable, and has low maintenance and use costs. The water inlet pipe 8 is connected to the water source, and the water pump 7 can pump water into the water spray pipe 10, and then spray it out from several spray heads 11, which can suppress the dust-laden air in the feed hopper 1. It is highly practical and worthy of promotion.

[0039] It should be noted that the model specifications of the control switch 12 and the water pump 7 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] The power supply and principle of the control switch 12 and the water pump 7 are clear to those skilled in the art and will not be described in detail here.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
