DETAILED DESCRIPTION

[0028] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model embodiment specifically provides a concrete production powder feeding device, please refer to Figure 1 and Figure 2 , including a protective cover 1 and a powder silo 2.

[0030] Among them, the top and bottom of the protective cover 1 are respectively fixed with a feed pipe 11 and a discharge pipe 12, and the powder bin 2 is arranged inside the protective cover 1 in a manner that it can slide up and down. During daily use, the powder is stored in the powder bin 2, and an electronic control valve 13 is arranged on the discharge pipe 12. When feeding and conveying is required, the powder can be conveyed to a suitable position by opening the control valve 13. At the same time, the powder bin 2 is slidably arranged to enable the distribution bin 2 to form a discharging mode of reciprocating vibration up and down inside the protective cover 1, so that the powder can be quickly separated and discharged from the powder bin 2 during discharging, reducing blockage.

[0031] During implementation, the top and bottom of the powder bin 2 are respectively fixed with a rubber cover 6 and a rubber tube 7, and the bottom of the powder bin 2 is integrally provided with a cone hopper 21. The top and bottom of the powder bin 2 are respectively fixedly connected with the protective cover 1 and the discharge pipe 12 through the rubber cover 6 and the rubber tube 7, that is, the top periphery of the powder bin 2 is connected with the inner wall of the protective cover 1 through the rubber cover 6, so that when the powder is fed into the inside of the powder bin 2 through the feed pipe 11, the rubber cover 6 can provide sealing protection, so that the powder slides along the inner wall of the rubber cover 6 to the inner wall of the powder bin 2;

[0032] The bottom of the cone hopper 21 is fixed to the discharge pipe 12 by the rubber tube 7, so that the powder is sent out from the discharge pipe 7 along the rubber tube 7. The rubber cover 6 and the rubber tube 7 can provide sealed transportation for the powder to avoid leakage. At the same time, it can also ensure that there is a sealed buffer space between the powder bin 2 and the protective cover 1 and the discharge pipe 12 when the powder bin 2 slides up and down, meeting the needs of powder feeding and transportation and the up and down vibration space of the powder bin 2.

[0033] Among them, the bottom of the powder silo 2 is connected to the protective cover 1 through a reset component 3, so that the powder silo 2 can provide a reset force through the reset component 3 when sliding back and forth. A vibration component 4 is installed on the reset component 3 to drive the powder silo 2 to slide through the vibration component 4. The outer end of the vibration component 4 is connected to a driving component 5 that provides driving force.

[0034] For details, please refer to Figure 3 The reset assembly 3 is provided at two locations, which are respectively provided at the left and right ends of the bottom of the powder bin 2 to provide a stable reset elastic force for the powder bin 2 and support the placement of the powder bin 2 in the protective cover 1. The reset assembly 3 includes a slide bar 31, a spring 32 and a limit plate 33. The top of the slide bar 31 is fixedly mounted on the discharge pipe 12, and the top of the slide bar 31 is fixedly mounted on the support 34. The inner side of the support 34 is fixed to the cone bucket 21.

[0035] The outer side of the slide bar 31 is slidably matched with the protective cover 1, so that the slide bar 31 can slide up and down in the protective cover 1, driving the powder bin 2 to keep sliding synchronously. After the bottom of the slide bar 31 slides out of the protective cover 1, a spring 32 is provided, and a limit plate 33 is fixed to the bottom of the slide bar 31. The upper and lower parts of the spring 32 are respectively fixed to the protective cover 1 and the limit plate 33, so that the slide bar 31 can provide a reset elastic force through the spring 32 after sliding, so as to drive the slide bar 31 to reset.

[0036] Furthermore, the number of vibration components 4 is set at two places to match the number of reset components 3 at two places, so as to provide stable vibration for the powder bin 2. The vibration component 4 includes a first gear 41, a convex surface 42 and a connecting rod 43. The first gear 41 is provided with a convex surface 42 inside, and the outer side of the connecting rod 43 is in sliding contact with the convex surface 42, and the outer end of the connecting rod 43 is vertically fixed to the slide bar 31, so that when the first gear 41 rotates, the convex surface 42 is driven to rotate, so that the convex surface 42 pushes the connecting rod 43 upward, so that the connecting rod 43 drives the slide bar 31 to slide upward, so that the powder bin 2 moves up, and when the convex surface 42 continues to slide to the concave position where the convex surface 42 is connected, the slide bar 31 is reset by the elastic force of the spring 32, so that the powder bin 2 is reset, thereby driving the powder bin 2 to vibrate reciprocatingly up and down through the rotation of the first gear 41, which helps to facilitate the discharge of powder.

[0037] Among them, a support rod 44 is vertically fixed on the periphery of the first gear 41, and one end of the support rod 44 away from the first gear 41 is vertically fixed to the synchronization disk 45. The first gear 41 and the synchronization disk 45 maintain coaxial cooperation, so that when the first gear 41 rotates, it can drive the synchronization disk 45 to rotate synchronously. The synchronization disk 45 is rotatably installed on the support seat 46, and the bottom of the support seat 46 is fixed to the protective cover 1 to provide a stable rotation installation effect for the first gear 41, which is conducive to keeping the first gear 41 in a stable rotation state.

[0038] For further information, please refer to Figure 2 and Figure 4 The driving assembly 5 includes a motor 51, an output rod 52 and a chain 53. The motor 51 is fixedly mounted on the outside of the protective cover 1, and the output shaft of the motor 51 penetrates the protective cover 1 and is fixed to the output rod 52, so that the motor 51 provides a rotational driving force for the output rod 52.

[0039] During implementation, the number of output rods 52 is set to two, which are respectively connected to two vibration components 4. The two output rods 52 are transmitted and matched through a chain 53. The motor 51 is connected to one of the output rods 52. The two output rods 52 are kept in synchronous rotation through the chain 53 to save energy and meet the power transmission needs of the equipment.

[0040] Specifically, the output rod 52 includes a rotating rod 521, a second gear 522 and a third gear 523. Both ends of the rotating rod 521 are rotatably installed in the protective cover 1, and the rotating rod 521 remains parallel to the connecting rod 43 to facilitate providing transmission force for the first gear 41. The outer end of the rotating rod 521 is fixedly provided with a second gear 522 for meshing with the chain 53, so that the two rotating rods 521 can maintain synchronous rotation transmission through the second gear 522 and the chain 53. The third gear 523 is fixedly installed in the middle part of the outer side of the rotating rod 521, and the side of the third gear 523 is meshed with the first gear 41, so that when the rotating rod 521 rotates, the first gear 41 can be driven to rotate synchronously through the third gear 523 to meet the up and down vibration power requirements of the powder bin 2.

[0041] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.
