[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] In order to solve the technical problem in the prior art that the vertical ascending screw conveying mechanism passively adds materials into the feed port of the screw conveying mechanism due to the fluidity of the materials, resulting in low material taking efficiency of the material taking device, the present invention provides a semi-closed spiral material taking device that can continuously lift and convey the materials to ensure the conveying efficiency of the spiral material taking device.

[0023] See also Figures 1-4 , Figures 1-4 A semi-enclosed spiral material collecting device in one embodiment of the present invention comprises a vertical material collecting mechanism 1 and a horizontal material collecting mechanism 2 connected to the lower end of the vertical material collecting mechanism 1, wherein the horizontal material collecting mechanism 2 comprises a mounting seat 21, a rotating shaft 22, a first spiral blade 23, a first driving member 24, a second driving member 25 and a material blocking member 26, wherein the mounting seat 21 is fixedly connected to the lower end of the vertical material collecting mechanism 1, the rotating shaft 22 is rotatably arranged in the mounting seat 21, the first spiral blade 23 is fixedly connected to the rotating shaft 22, the material blocking member 26 is rotatably connected to the rotating shaft 22, and the The material blocking member 26 is located on one side of the first spiral blade 23, and an opening is formed on the other side of the first spiral blade 23 corresponding to the material blocking member 26. One end of the opening is connected to the feed port of the vertical collecting mechanism 1. The first driving member 24 is arranged on the mounting seat 21 and connected to the rotating shaft 22. The first driving member 24 is used to drive the rotating shaft 22 to rotate around its own axis. The second driving member 25 is arranged on the mounting seat 21 and connected to the material blocking member 26. The material blocking member 26 is driven to rotate by the second driving member 25 to adjust the direction of the opening.

[0024] Based on the above solution, the pitch of the first spiral blade 23 toward the lower end of the vertical lifting cylinder 11 is gradually reduced, which can avoid conveying large pieces of material into the vertical lifting cylinder 11 and at the same time increase the feeding rate at the feed port.

[0025] Specifically, it is necessary to extend the lower end of the vertical aggregation mechanism 1 and the horizontal aggregation mechanism 2 into the material bin, and the horizontal aggregation mechanism 2 is arranged along the radial direction of the material bin. The material bin rotates around its own axis. Under the action of the material blocking member 26, the first spiral blade 23 rotates to push the material in the material bin to the feed port of the vertical aggregation mechanism 1.

[0026] It should be noted that the semi-closed spiral feeding device can change the material fluidity of the existing spiral conveying mechanism, passively add the material to the feed port of the spiral conveying mechanism, change the passive feeding to active feeding, and cooperate with the horizontal aggregation mechanism through the rotation of the material bin to maximize the transfer of materials in the material bin to the feed port of the vertical aggregation mechanism for accumulation, ensuring that the vertical aggregation mechanism can continuously transport the materials in the material bin.

[0027] In this specific embodiment, please refer to Figure 1 The vertical material collection mechanism 1 includes a vertical lifting cylinder 11, a rotating shaft 12, a second spiral blade 13 and a reduction motor. The vertical lifting cylinder 11 is fixedly connected to the mounting seat 21. The rotating shaft 12 is coaxial and rotatably arranged on the vertical lifting cylinder 11. The second spiral blade 13 is fixed on the rotating shaft 12. The reduction motor is arranged at the upper end of the vertical lifting cylinder 11, and the output end of the reduction motor is connected to one end of the rotating shaft 12, wherein the axis of the rotating shaft 22 and the axis of the rotating shaft 12 are perpendicular to each other.

[0028] It should be noted that the lower end of the vertical lifting cylinder 11 is provided with a feed port connected to the opening, and the upper end of the vertical lifting cylinder 11 is provided with a discharge port; in other embodiments, a third spiral blade is also fixed on the rotating shaft 12, and the end of the third spiral blade close to the second spiral blade 13 corresponds to the discharge port of the vertical lifting cylinder 11; specifically, by setting the spiral directions of the third spiral blade and the second spiral blade 13 in opposite directions, the material in the vertical lifting cylinder 11 can be squeezed out through the discharge port, thereby improving the discharge rate.

[0029] It should be noted that the blocking member 26 is not limited to a specific structure, as long as it can block one side of the first spiral blade 23 so that an opening is formed on the other side of the first spiral blade 23 .

[0030] In this specific embodiment, the material blocking member 26 includes an arc-shaped baffle 261 and connecting blocks 262 fixed at the opposite ends of the arc-shaped baffle 261. The two connecting blocks 262 are rotatably connected to the rotating shaft 22, and an opening is formed on the other side of the first spiral blade 23 corresponding to the arc-shaped baffle 261.

[0031] In this specific embodiment, the first driving member 24 includes a driving motor 241, a reducer 242 and a first chain 243. The driving motor 241 and the reducer 242 are fixedly connected to the mounting base 21, and the driving motor 241 is connected to the reducer 242. The output end of the reducer 242 is provided with a first driving sprocket 244, and a first driven sprocket 245 is fixed on the rotating shaft 22. The first chain 243 is connected between the first driving sprocket 244 and the first driven sprocket 245.

[0032] In addition, the second driving member 25 includes a servo motor 251 and a second chain 252. The servo motor 251 is fixedly connected to the mounting seat 21. A second driving sprocket 253 is fixedly provided at the output end of the servo motor 251. A second driven sprocket 254 is fixedly provided on the connecting block 262, and the second driven sprocket 254 is rotatably sleeved on the rotating shaft 22. The second chain 252 is connected between the second driving sprocket 253 and the second driven sprocket 254.

[0033] It should be noted that the servo motor 251 drives the second chain 252 to rotate, thereby driving the arc-shaped baffle 261 to rotate about the axis of the rotating shaft 22. Specifically, the arc-shaped baffle 261 can also rotate one circle about the rotating shaft 22. When the arc-shaped baffle 261 rotates to the bottom of the mounting seat 21, an opening is formed between the arc-shaped baffle 261 and the top of the mounting seat 21. At this time, the horizontal collecting mechanism 2 can also be inserted into the material bin and located below the material pile. There is no need to drive the material bin to rotate, and continuous feeding can be achieved by relying on the fluidity of the material.

[0034] Based on the above solution, extension plates 260 are provided on opposite sides of the arc-shaped baffle 261, and the widths of the two extension plates 260 toward the opening are arranged in a decreasing and increasing manner. Specifically, when the arc-shaped baffle 261 rotates, the extension plates 260 can be inserted into the material in the collection bin to block the material.

[0035] Based on the above solution, the mounting base 21 is provided with a first protective cover 211 and a second protective cover 212. The drive motor 241 and the reducer 242 are located in the first protective cover 211, and the servo motor 251 is located in the second protective cover 212. It should be noted that a plurality of heat dissipation holes are provided on the first protective cover 211 and the second protective cover 212.

[0036] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the present invention is described in detail:

[0037] By arranging the vertical collecting mechanism 1 and the horizontal collecting mechanism 2 in a rotatable material bin, and ensuring that the horizontal collecting mechanism 2 is arranged along the radial direction of the material bin, the servo motor 251 drives the second chain 252 to rotate, thereby driving the arc-shaped baffle 261 to rotate, so that the extension plate 260 is inserted into the material pile. When the material bin rotates, the arc-shaped baffle 261 can block the material. When the first driving member 24 drives the rotating shaft 22 to rotate, the first spiral blade 23 can transport the material to the feed port of the vertical collecting mechanism 1.

[0038] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
