Description

Technical Field

[0001] This utility model belongs to the technical field of coal leveling machines, and more specifically, it relates to an adjustable cylindrical spiral bidirectional coal leveling machine. Background Technology

[0002] In coal loading, unloading, and stacking, coal levelers are crucial pieces of equipment, playing a vital role in ensuring flat coal stacking, optimizing space utilization, and facilitating subsequent transportation and use. Traditional coal levelers mostly employ a fixed helical structure in their design; once the helical spacing and angle are determined, they are difficult to change during actual use.

[0003] Different coal storage sites vary in width, height, and shape. A fixed helix angle is difficult to adapt to diverse site requirements, which may prevent the coal leveler from working effectively in certain areas, reducing the applicability and flexibility of the equipment. At the same time, the non-adjustable pitch of the helical coal leveler limits the working range of the machine to a certain extent.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an adjustable cylindrical spiral bidirectional coal leveling machine in order to achieve a more practical value. Summary of the Invention

[0008] Preferably, the quick-release mechanism includes a connecting pin, which is fixed to one end of the transmission roller, and one end of the connecting pin passes through the adjusting arm and extends to one side thereon.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] This utility model provides an adjustable cylindrical spiral bidirectional coal leveling machine, including a boom 1, a connecting column 2 rotatably mounted on the inner wall of the boom 1, an adjusting arm 3 mounted on the outer side of the connecting column 2, and a coal leveling mechanism for leveling coal on the inner wall of the adjusting arm 3. The coal leveling mechanism includes a transmission roller 4, which is rotatably mounted on the inner wall of the adjusting arm 3, and a first spiral blade 5 is mounted on the outer side of the transmission roller 4. The operation of the transmission roller 4 is driven by an external controller, which drives the transmission roller 4 to rotate, thereby driving the first spiral blade 5 to perform coal leveling work.

[0027] The boom 1 is equipped with a transmission assembly on one side, and the adjusting arm 3 is equipped with quick-release mechanisms on both sides. The transmission assembly includes a mounting housing 6, which is installed on one side of the boom 1. A servo motor 8 is installed on the inner wall of the mounting housing 6. A connecting shaft 9 is installed at the output end of the servo motor 8. The output end of the connecting shaft 9 extends through to the inner side of the boom 1 and is equipped with a drive gear 10. A driven gear 11 is meshed on one side of the drive gear 10. The driven gear 11 is installed on the outer side of the connecting column 2. The servo motor 8 drives the drive gear 10 and the driven gear 11 to drive the adjusting arm 3 to adjust its angle, so that the first spiral blade 5, the second spiral blade 14, and the third spiral blade 15 can freely adjust their contact height with the coal.

[0028] The quick-release mechanism includes a connecting pin 12, which is fixed to one end of the transmission roller 4. One end of the connecting pin 12 passes through the adjusting arm 3 and extends to one side. A slot 16 is provided at one end of the connecting pin 12. A second transmission roller 13 is provided on the inner wall of the slot 16. Two locking posts 20 are installed on the outer side of the second transmission roller 13. Two slots 17 are provided on the outer side of the connecting pin 12 corresponding to the locking posts 20. The quick-release mechanism also includes two springs 19, which are fixed to the locking posts 20 on their respective sides. Two grooves 18 are provided on the outer side of the second transmission roller 13 corresponding to the springs 19. The bottom of spring 19 is fixed to the bottom of the corresponding groove 18. By inserting the second transmission roller 13 into the slot 16, the force of spring 19 allows the locking post 20 to be used to lock the groove 17, thereby fixing the second transmission roller 13 to the transmission roller 4 via the connecting pin 12, thus completing the quick installation. This setting, combined with the above-mentioned transmission mechanism, enables the device to meet the requirements of different areas and different coal stacking heights, and satisfies the disassembly and installation of the spiral blades, thereby indirectly changing the working range of the spiral blades, increasing the working range and span of the spiral blades, and improving the flexibility and applicability of the device.

[0029] The two locking posts 20 are configured to match the diameter of the inner walls of the two grooves 18.

[0030] The quick-release mechanism is divided into two symmetrically arranged on both sides of the adjusting arm 3, and the outer sides of the second transmission roller 13 on both sides are respectively equipped with a second spiral blade 14 and a third spiral blade 15 for leveling coal.

[0031] Each locking pin 20 has a bevel on its top side, which makes it easier for the locking pin 20 to enter the slot 16.

[0032] A protective housing 7 is installed on one side of the inner wall of the boom 1. The driving gear 10 and the driven gear 11 are both located inside the protective housing 7. The protective housing 7 can protect the relevant mechanical mechanisms.

[0033] The working principle of this embodiment is as follows: the transmission roller 4 is driven to rotate by the external controller, which drives the first spiral blade 5 to perform coal leveling. When the servo motor 8 is started, it drives the drive gear 10 and the driven gear 11 to drive the connecting column 2 to rotate. Since the connecting column 2 is connected to the adjusting arm 3, the angle of the adjusting arm 3 can be adjusted, so that the first spiral blade 5, the second spiral blade 14, and the third spiral blade 15 can freely adjust their contact height with the coal.

[0034] Secondly, quick-release mechanisms are provided on both sides of the adjusting arm 3, including components such as connecting pin 12, second drive roller 13, locking pin 20, and spring 19. When the two second drive rollers 13 are inserted into the slots 16 of the connecting pin 12, the two locking pins 20 are driven by the second drive rollers 13 to contact the connecting pin 12. Since one side of the locking pin 20 is provided with an inclined surface, the locking pin 20 compresses the spring 19 and lowers it under the squeezing action. After the second drive roller 13 enters the slot 16, when the locking pin 20 reaches the slot 17, the spring 19 reverses its action. Forcefully eject the locking pin 20 so that it locks into the locking groove 17, thus completing the quick installation of the second drive rollers 13 on both sides. Conversely, during disassembly, simply press the two locking pins 20 and push them out of the locking groove 17, then pull out the second drive rollers 13. Through the quick-release mechanism, the spiral blades can be disassembled and installed according to the requirements of different areas and different coal stacking heights, thereby indirectly changing the working range of the spiral blades, increasing the working range and span of the spiral blades, and improving the flexibility and applicability of the device.

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
