[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] In order to solve the technical problem that dust generated when a mixing barrel discharges materials pollutes the air, the utility model provides a mixing device with a dust collecting function, which can prevent dust from polluting the air.

[0027] It should be noted that the stirring device with dust collection function described in the utility model is used for but not limited to fertilizers, etc. For the convenience of explanation, in the utility model, only an example of a stirring device with dust collection function applied to fertilizers is used for explanation. The principle of applying a stirring device with dust collection function to other types of equipment is essentially the same as the principle applied to fertilizers, which will not be repeated here.

[0028] See also Figure 1 - Figure 3 ,in Figure 1 This is a structural schematic diagram of a stirring device with a dust collecting function in an embodiment of the utility model. The stirring device with a dust collecting function includes a shell 1, a stirring member 2, a lifting member 3 and a negative pressure component 4. The outer wall of the shell 1 is provided with a feed inlet 11 and a discharge port 12. The stirring member 2 includes a stirring rod 21 and a motor 22. The stirring rod 21 is located in the shell 1. The motor 22 is transmission-connected to the stirring rod 21. The stirring rod 21 is axially provided with a cavity 211. The lifting member 3 is located on one side of the stirring rod 21 and is used to drive the bottom end of the stirring rod 21 to open and close the discharge port 12. One end of the negative pressure component 4 is connected to the cavity 211 and negatively sucks the bottom end of the stirring rod 21.

[0029] In this embodiment, through the setting of the lifting member 3, the bottom end of the stirring rod 21 can block the discharge port 12, so that the shell 1 has a sealed stirring space, which is convenient for stirring; the stirring rod 21 is provided with a cavity 211 in the axial direction, and the cavity 211 is connected to the negative pressure component 4, so that the bottom end of the stirring rod 21 can absorb the dust generated when the shell 1 is discharged, effectively avoiding dust pollution of the workshop air and ensuring the respiratory health of the staff.

[0030] First, a screening device is installed below the discharge port 12 to ensure that the stirred fertilizer can directly fall into the screening device for screening; then, the lifting member 3 drives the bottom end of the stirring rod 21 to block the discharge port 12, and the staff pours the fertilizer into the shell 1 through the feed port 11. At the same time, the motor 22 is started to drive the stirring rod 21 to stir the fertilizer in the shell 1; finally, after the fertilizer is stirred, the lifting member 3 drives the stirring rod 21 to open the discharge port 12 for discharge. At the same time, the negative pressure component 4 is started to make the cavity 211 in a negative pressure state, and the dust generated by the fertilizer during the falling process will enter the cavity 211.

[0031] It should be noted that, in order to facilitate loading and unloading, the feed port 11 is opened at the top of the shell 1 , and the discharge port 12 is opened at the bottom of the shell 1 .

[0032] In one embodiment, see Figure 3 A stirring port 13 is provided at the top of the shell 1, and a stirring rod 21 is rotatably sleeved on the stirring port 13 and can reciprocate along the axial direction of the stirring port 13. The top end of the stirring rod 21 passes through the stirring port 13 and is fixedly connected to an outer gear ring 23. The motor 22 is located on one side of the stirring rod 21, and the motor 22 is fixedly connected to a gear 221, and the outer gear ring 23 meshes with the gear 221.

[0033] In this embodiment, the motor 22 uses a servo motor 22, so that the stirring rod 21 can rotate forward and reverse, thereby improving the stirring effect of the fertilizer. One end of the stirring support rod 25 is fixedly connected to the stirring rod 21, and the other end of the stirring support rod 25 extends in a direction away from the stirring rod 21.

[0034] Furthermore, in order to facilitate the installation of the motor 22, a boss is installed on the top of the shell 1, the gear 221 is rotatably connected to the boss, the movable end of the motor 22 is fixedly connected to the gear 221, and the fixed end of the motor 22 is fixedly connected to the top of the shell 1 through a support block to ensure the stability of the fixed end of the motor 22 during operation.

[0035] In one embodiment, see Figure 1 and Figure 3 The outer gear ring 23 is coaxial with the cavity 211 , and the tooth width of the outer gear ring 23 is twice the tooth width of the gear 221 .

[0036] In this embodiment, the cavity 211 is opened along the length direction of the stirring rod 21, that is, the stirring rod 21 has a hollow structure, and the tooth width of the outer gear ring 23 is twice the tooth width of the gear 221, so that no matter whether the outer gear ring 23 is raised or lowered, the outer gear ring 23 and the gear 221 are always meshed, that is, the stirring rod 21 can always stir the fertilizer. When the fertilizer after stirring needs to be discharged from the discharge port 12 to the screening device, the stirring rod 21 can still rotate, thereby improving the discharge efficiency.

[0037] In one embodiment, see Figure 1 and Figure 3 The stirring port 13 is coaxial with the discharge port 12, the bottom end of the stirring rod 21 passes through the discharge port 12, the bottom end of the stirring rod 21 is fixedly connected to the first funnel 24, and the cross-sectional diameter of the stirring rod 21, the inner diameter of the discharge port 12 and the bottom end diameter of the first funnel 24 increase successively.

[0038] In this embodiment, the cross-sectional diameter of the stirring rod 21 is smaller than the inner diameter of the discharge port 12, so that when the stirring rod 21 passes through the discharge port 12, a gap is left between the stirring rod 21 and the discharge port 12, which is convenient for discharging the material to the screening device below; the inner diameter of the discharge port 12 is smaller than the bottom end diameter of the first funnel 24, so that the first funnel 24 will block the discharge port 12 after rising, thereby preventing the fertilizer from leaking from the discharge port 12 during the stirring process.

[0039] It should be noted that when the fertilizer falls from the discharge port 12 to the screening device, it will hit the first funnel 24. By utilizing the ductility of the side wall of the first funnel 24, the fertilizer will spread in all directions to the screening device, effectively avoiding the fertilizer from accumulating in one place and reducing the screening efficiency.

[0040] It should be noted that in order to ensure that the first funnel 24 can block the discharge port 12 when it is raised or lowered, the length of the stirring rod 21 that passes through the discharge port 12 must be less than the tooth width of the gear 221 .

[0041] Furthermore, the provision of the first funnel 24 may further enhance the dust suction effect of the cavity 211 , so that more dust generated by the screening device during the screening process is sucked into the cavity 211 .

[0042] In one embodiment, see Figure 3 A stirring support rod 25 is fixedly connected to the side wall of the stirring rod 21 . The number of the stirring support rods 25 is at least two, and each stirring support rod 25 is distributed along the length direction of the stirring rod 21 .

[0043] In this embodiment, a plurality of stirring support rods 25 are arranged along the length direction of the stirring rod 21, so that the fertilizers in each layer are mixed more evenly, thereby improving the mixing effect of the fertilizers.

[0044] In one embodiment, see Figure 1 - Figure 2 The lifting member 3 includes a lifting ring 31 and a cylinder 32. The bottom of the lifting ring 31 is fixedly connected with a ring groove 311. The top of the outer gear ring 23 is provided with a convex ring 231. The ring groove 311 is slidably embedded in the convex ring 231. The cylinder 32 is located on one side of the lifting ring 31. The cylinder 32 is used to drive the lifting ring 31 to move up and down, and drive the stirring rod 21 to move up and down.

[0045] In this embodiment, since the annular groove 311 is slidably embedded in the convex ring 231, on the one hand, when the outer gear ring 23 and the stirring rod 21 rotate, the lifting ring 31 will not be driven to rotate, thereby ensuring the stability of the negative pressure assembly 4; on the other hand, when the lifting ring 31 is lifted or lowered, it will drive the outer gear ring 23 and the stirring rod 21 to lift and lower together. Through the lifting and lowering of the stirring rod 21, the first funnel 24 can block or open the discharge port 12, so that the fertilizer can leak from the discharge port 12 during the stirring process.

[0046] In one embodiment, see Figure 1 - Figure 2 The number of the cylinders 32 is at least two, and the cylinders 32 are evenly distributed along the circumferential direction of the lifting ring 31 and are fixedly connected to the lifting ring 31 .

[0047] In this embodiment, the preferred number of cylinders 32 is two, and they are relatively arranged on both sides of the lifting ring 31. The fixed end of the cylinder 32 is fixedly connected to the top of the shell 1, and the movable end of the cylinder 32 is fixedly connected to the lifting ring 31. The two cylinders 32 are then controlled by the PLC to operate synchronously, so that the two cylinders 32 can realize the lifting function of the lifting ring 31 together.

[0048] In one embodiment, see Figure 1 - Figure 3The negative pressure assembly 4 includes a telescopic tube 41, a conveying tube 42, a dust collecting box 43 and an exhaust fan 44. One end of the telescopic tube 41 is fixedly connected to the top of the lifting ring 31, and the other end of the telescopic tube 41 is connected to the conveying tube 42. The end of the conveying tube 42 away from the telescopic tube 41 is connected to the dust collecting box 43. The exhaust fan 44 is connected to the dust collecting box 43 and makes the telescopic tube 41 and the conveying tube 42 in a negative pressure state.

[0049] In this embodiment, the telescopic tube 41 is a flexible accordion structure. The telescopic tube 41 performs telescopic movement according to the lifting and lowering of the stirring rod 21, which does not affect the normal operation of the conveying tube 42. In addition, since the conveying tube 42, the telescopic tube 41, the outer gear ring 23 and the cavity 211 are connected, the exhaust fan 44 can make the cavity 211 in a negative pressure state, so that the dust passes through the first funnel 24 into the cavity 211 and is discharged into the dust collecting box 43, effectively preventing dust from polluting the outside air.

[0050] Furthermore, the dust collecting box 43 is provided with a discharge port and a discharge door. When the inside of the dust collecting box 43 needs to be cleaned, the discharge door is opened and the dust is discharged from the discharge port.

[0051] In one embodiment, see Figure 1 - Figure 3 The feed port 11 is fixedly connected to a second funnel 111 .

[0052] In this embodiment, the function of the second funnel 111 is to facilitate the feeding of fertilizers, so that more fertilizers can fall into the shell 1 along the second funnel 111 .

[0053] In one embodiment, see Figure 1 - Figure 3 A bracket 14 is fixedly connected to the outer wall of the shell 1.

[0054] In this embodiment, for the stability of the shell 1, the number of the brackets 14 is at least three. At the same time, in order to expand the operating space of the screening device below the shell 1, the shape of the brackets 14 is L-shaped.

[0055] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail:

[0056] First, a screening device is installed below the discharge port 12 to ensure that the stirred fertilizer can directly fall into the screening device for screening; then, the cylinder 32 is started to lift the lifting ring 31, and under the connection between the ring groove 311 and the convex ring 231, the outer gear ring 23 and the stirring rod 21 rise with the lifting ring 31, and the telescopic tube 41 shrinks until the first funnel 24 blocks the discharge port 12; then, the staff pours the fertilizer into the shell 1 through the feed port 11, and at the same time, the motor 22 is started to drive the stirring rod 21 to drive the stirring support rod 25 to stir the fertilizer in the shell 1; finally, after the fertilizer is stirred, the cylinder 32 is started , the lifting ring 31 is lowered, and the fertilizer falls and hits the side wall of the first funnel 24 as the discharge port 12 is opened, and falls evenly to the screening device in all directions along the inclined side wall of the first funnel 24. At the same time, the exhaust fan 44 is started, so that the cavity 211 is in a negative pressure state, and the dust generated by the fertilizer during the falling process and the dust generated during the screening process will be sucked into the cavity 211, and discharged into the dust collecting box 43 along the cavity 211, the outer gear ring 23, the lifting ring 31, the telescopic tube 41 and the conveying tube 42 in turn, which effectively prevents the dust from spreading everywhere and polluting the workshop air, and ensures the respiratory health of the staff.

[0057] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model.
