Description

Technical Field

[0001] The invention relates to the technical field of crushing devices, in particular to a crushing device for a mobile silo. Background Art

[0002] In the pharmaceutical process of our company, raw materials are crushed and classified according to production needs. The crushed raw materials need to be transported to the production line through a mobile silo. Therefore, the bottom discharge port of the crushing device needs to be elevated so that the crushed raw materials can be placed in the mobile silo. The existing device puts the raw materials into the crushing device, and the raw materials are crushed by the rotation of the conical crushing head of the crushing device and the squeezing of the inner wall of the crushing device. However, in actual operation, the gap between the conical crushing head and the inner wall is small, and the crushed raw materials are easily blocked in the gap, making it impossible to discharge the crushed raw materials. The existing technology installs a vibrating hammer on the crushing device to discharge the materials through vibration and knocking, but the vibration amplitude of the vibrating hammer is large, which can easily cause damage to the inside of the crushing device. Secondly, the existing device can only perform coarse crushing or fine crushing on the raw materials, and cannot obtain coarse and fine crushing raw materials at the same time, resulting in the need for subsequent equipment to operate, with high economic cost and low efficiency. Summary of the invention

[0003] In order to solve the technical problems mentioned in the above background technology, the present invention provides a crushing device for a mobile silo, and the technical solution adopted is as follows:

[0004] It includes a shell, a bracket is arranged at the bottom of the shell, and a mobile material bin is arranged at the bottom of the bracket. The character is characterized in that a feed port is arranged on the left part of the shell, a reduction motor is arranged on the upper part of the shell and the reduction motor forms a seal with the upper part of the shell, a conical crushing head is arranged in the shell, the conical crushing head is connected with the output end of the reduction motor, a gap is arranged between the conical crushing head and the inner wall of the shell, a top plate is arranged at the lower side of the conical crushing head, a plurality of top rods are arranged on the top plate, a through hole is arranged at the center of the top plate, a fixed bin is arranged at the lower side of the top plate, a bearing is arranged on the fixed bin, a rotating shaft is arranged at the bottom of the conical crushing head, the rotating shaft passes through the through hole and the diameter of the through hole is larger than the diameter of the rotating shaft, the rotating shaft is connected with the bearing and extends to the inside of the fixed bin, a rotating mechanism is arranged in the fixed bin, a lifting mechanism that moves up and down with the rotation of the rotating mechanism is arranged on the rotating mechanism, and one end of the lifting mechanism passes through the upper part of the fixed bin and is fixedly connected with the top plate.

[0005] Furthermore, the rotating mechanism includes a turntable, which is fixedly connected to the rotating shaft. A group of slope blocks distributed along the circumferential direction are arranged on the turntable, one end of the slope block is sloped, and a lifting mechanism is arranged on the turntable.

[0006] Furthermore, the lifting mechanism includes a lifting rod, one end of which passes through the upper part of the fixed bin and is fixedly connected to the top plate, and the other end is provided with a pulley, and the pulley is in active contact with the turntable or the slope block.

[0007] Furthermore, a hopper is arranged in the shell.

[0008] Furthermore, the upper portion of the top plate is a conical surface.

[0009] Furthermore, the upper portion of the push rod is a conical surface.

[0010] Furthermore, the upper portion of the fixed bin is a conical surface.

[0011] Furthermore, fixing rods are arranged around the fixing bin, and the fixing rods are fixedly connected to the inner wall of the shell.

[0012] The present invention has the following advantages:

[0013] When the reduction motor drives the conical crushing head to rotate, the conical crushing head drives the rotating shaft to rotate, and the rotating shaft drives the rotating mechanism to rotate, so that the lifting mechanism on the rotating mechanism drives the top plate and the top rod to intermittently lift and lower, and the top rod intermittently pushes the gap between the inner wall of the shell body and the conical crushing head, so that the gap can be unblocked when raw materials are blocked, making it convenient to unload materials. The present invention does not cause damage to the inside of the crushing device and has low cost.

[0014] When the push rod is pushed into the gap, a new gap is formed between the push rod and the conical crushing head. This gap is smaller than the original gap, so that the part of the raw material falling into the gap between the conical crushing head and the push rod is finely crushed. Since the push rod is intermittently raised and lowered, the device not only coarsely crushes the raw material by the conical crushing head and the inner wall of the shell, but also intermittently finely crushes the raw material by the conical crushing head and the push rod, so that the whole crushing device produces both coarsely crushed raw material and finely crushed raw material.

[0026] 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. Example

[0027] Please refer to Figure 1 The present invention provides a crushing device for a mobile silo, comprising a shell 1, a bracket 2 is arranged at the bottom of the shell 1, the shell 1 is raised by the bracket 2, so that the mobile silo 3 can be pushed to the lower part of the shell 1, so that the mobile silo 3 can receive materials. The mobile silo 3 is arranged at the bottom of the bracket 2, characterized in that a feed port 4 is arranged on the left side of the shell 1, and the raw materials to be crushed enter the shell 1 through the feed port 4, a reduction motor 5 is arranged on the upper part of the shell 1, and the reduction motor 5 forms a seal with the upper part of the shell 1, a conical crushing head 6 is arranged in the shell 1, the conical crushing head 6 is connected to the output end of the reduction motor 5, the reduction motor 5 drives the conical crushing head 6 to rotate slowly, a gap is arranged between the conical crushing head 6 and the inner wall of the shell 1, the raw materials are squeezed and crushed by the rotating conical crushing head 6 and the inner wall of the shell 1, and the crushed raw materials fall through the gap.

[0028] Please refer to Figure 2-5A top plate 7 is arranged at the lower side of the conical crushing head 6, and a plurality of push rods 8 are arranged on the top plate 7. A through hole 9 is arranged at the center of the top plate 7. A fixed bin 10 is arranged at the lower side of the top plate 7, and a bearing 11 is arranged on the fixed bin 10. A rotating shaft 12 is arranged at the bottom of the conical crushing head 6, and the rotating shaft 12 passes through the through hole 9 and the diameter of the through hole 9 is larger than the diameter of the rotating shaft 12. The conical crushing head 6 drives the rotating shaft 12 to rotate, and the rotating shaft 12 does not contact the top plate 7. The rotating shaft 12 is connected to the bearing 11 and extends to the inside of the fixed bin 10. A rotating mechanism is arranged in the fixed bin 10, and the rotating shaft 12 rotates in the bearing 11 and drives the rotating mechanism to rotate. A lifting mechanism that moves up and down with the rotation of the rotating mechanism is arranged on the rotating mechanism. With the rotation of the rotating mechanism, the lifting mechanism intermittently rises and falls on the rotating mechanism, and the lifting mechanism drives the top plate 7 and the push rod 8 to rise and fall, and the push rod 8 dredges the raw materials at the gap, and one end of the lifting mechanism passes through the upper part of the fixed bin 10 and is fixedly connected to the top plate 7.

[0029] Please refer to Figure 6-7 The rotating mechanism includes a turntable 13. The conical crushing head 6 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the turntable 13 to rotate. The turntable 13 is fixedly connected to the rotating shaft 12. A group of slope blocks 14 distributed along the circumferential direction are arranged on the turntable 13. One end of the slope block 14 is sloped. A lifting mechanism is arranged on the turntable 13. The turntable 13 rotates counterclockwise to make the slope block on the turntable 13 rotate counterclockwise. The slope end of the slope block 13 contacts the lifting mechanism to make the lifting mechanism rise. The lifting mechanism maintains an elevated state in the flat section of the slope block 14. When the slope block 14 passes the bottom of the lifting mechanism, it suddenly falls. After that, the lifting mechanism contacts the turntable 13 for a period of time. This scheme enables the lifting mechanism to achieve intermittent lifting.

[0030] Please refer to Figure 2 , 9 10. The lifting mechanism includes a lifting rod 15. One end of the lifting rod 15 passes through the upper part of the fixed bin 10 and is fixedly connected to the top plate 7. The other end is provided with a pulley 16. The pulley 16 is in active contact with the turntable 13 or the ramp block 14. The slider 14 passes through the bottom of the pulley 16, so that the pulley 16 is first lifted up. The height after lifting is maintained for a period of time. Then, when the slider 14 passes, the pulley 16 falls and contacts with the turntable 13.

[0031] Please refer to Figure 1 A hopper 17 is provided in the shell 1 , and the crushed raw materials fall into the hopper 17 , fall through the hopper 17 , and fall into the mobile silo 3 at the lower part of the hopper 17 .

[0032] The upper part of the top plate 7 is a conical surface, and when part of the crushed raw materials falls on the top plate 7, it is easy to slide down.

[0033] The upper part of the push rod 8 is a conical surface, so that the push rod 8 can more easily push open the sealing layer of the raw material at the gap when it rises.

[0034] The upper part of the fixed bin 10 is a conical surface, so when part of the crushed raw materials falls on the fixed bin 10, it is easy to slide down.

[0035] Fixed rods 18 are arranged around the fixed bin 10 , and the fixed rods 18 are fixedly connected to the inner wall of the shell 1 , so that the fixed bin 10 is fixed in the shell 1 .

[0036] Working principle of the present invention:

[0037] The raw material enters the shell 1 through the feed port 4, and the reduction motor 5 is started. The reduction motor 5 drives the cone crushing head 6 to rotate slowly. The raw material is crushed through the gap between the rotating cone crushing head 6 and the inner wall of the shell 1. At this time, the raw material is roughly crushed. The cone crushing head 6 drives the rotating shaft 12 to rotate in the bearing 11. The rotating shaft 12 drives the turntable 13 to rotate counterclockwise. The slope block 14 on the turntable 13 also rotates counterclockwise in the circumferential direction. The slope end of the slope block 14 first contacts the bottom of the pulley 16, and the pulley 16 rotates. With the advancement of the slope end of the slope block 14, the pulley 16 drives the lifting rod 15 to pass through the upper part of the fixed bin 10 and rise. At the same time, the lifting rod 15 drives the top plate 7 and the top rod 8 to rise, and the top rod 8 pushes into the cone crushing head 6 and the shell. 1, the raw materials blocked in the gap are cleared, so that the blocked raw materials fall from the gap. At this time, the pulley 16 continues to run on the flat part of the upper part of the slope block 14 for a short period of time. During this process, a new smaller gap is formed between the push rod 8 and the conical crushing head 6, and the raw materials are pressurized and crushed into smaller raw materials by the push rod 8 and the conical crushing head 6. This is fine crushing. When the slope block 14 passes through the pulley 16, the pulley 16 suddenly falls on the turntable 13, the pulley 16 rotates on the turntable 13, and the push rod 8 also descends and leaves between the shell 1 and the conical crushing head 6. During this process, the raw materials return to the coarse crushing state, and the push rod 8 realizes intermittent lifting. The present invention obtains coarsely crushed raw materials and finely crushed raw materials at the same time.

[0038] The present invention is simple to operate, convenient to use, and suitable for comprehensive promotion and application. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
