Description

Technical Field

[0001] The utility model relates to the technical field of loading machines, and particularly relates to a pneumatic speed-regulating concrete loading machine for mines. Background Technique

[0002] Most of the existing screw loading machines rely on motors as power sources. Although motor drive has advantages in terms of efficiency and power output, under the special conditions of mines, the sealing and anti-corrosion performance of motors are often difficult to reach an ideal state, and they are easily invaded by moisture, dust, and corrosive gases, resulting in an increase in motor failure rates and poor anti-corrosion effects.

[0003] In addition, their cylinders are generally constructed of metal materials. When undertaking the task of transporting abrasive materials such as concrete, their wear resistance is significantly insufficient. At the same time, it is rather inconvenient to clean the solidified concrete in the cylinder. In the Chinese Utility Model Patent Application No.: CN202321143037.0, there is disclosed a screw conveyor that is convenient for cleaning, in which a housing is slidably connected to the top edge of the screw conveyor body, and the interior is cleaned by disassembling and assembling the housing. However, the concrete mostly adheres to the lower inner wall and side wall of the cylinder, and due to the obstruction of the screw conveyor shaft, the cleaning is still rather inconvenient.

[0004] Therefore, it is very necessary to propose a pneumatic speed-regulating concrete loading machine for mines to solve the above problems. Content of the Utility Model

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0028] Please refer to Figures 1-4 As shown, a pneumatic speed-regulating type concrete feeding machine for mining includes a frame 3 obliquely arranged above a support 10. A rubber conveying trough 8 is fixedly connected to the lower part of the frame 3 through a connecting piece. A spiral conveyor shaft 2 is arranged inside the rubber conveying trough 8. The spiral conveyor shaft 2 is rotationally connected to the frame 3 and is driven to rotate by a driving mechanism for pushing the material in the rubber conveying trough 8 from the feeding end to the discharging end; the connecting piece includes a pressing plate 17 and an angle steel 18. The pressing plate 17 and the angle steel 18 are clamped on the inner and outer sides of the rubber conveying trough 8 through bolts, and the angle steel 18 is fixedly connected to the frame 3. Preferably, the angle steel 18 is fixedly connected to the frame 3 through bolts.

[0029] By using the rubber conveying trough 8 to convey concrete, it has better wear resistance, corrosion resistance, compressive elasticity and anti-slip performance compared with the traditional metal conveying trough; at the same time, its detachable connection through the connecting piece makes its disassembly and cleaning more convenient.

[0030] Specifically, the driving mechanism includes a pneumatic motor 6, and the spiral conveyor shaft 2 is driven to rotate by the pneumatic motor 6.

[0031] The pneumatic motor 6 is used as the power source, and the rotational speed can be precisely controlled by adjusting the pressure of the air source to meet the feeding requirements under different working conditions. At the same time, the pneumatic motor 6 has good explosion-proof effect and can work stably in harsh environments such as high temperature, humidity, and high dust, making it suitable for special environments like mines.

[0032] By setting the rubber conveying trough 8 and the pressing plate 17 to clamp and fix both sides of the rubber conveying trough 8, under the clamping of the pressing plate 17 and the angle steel 18, the rubber conveying trough 8 undergoes elastic deformation, increasing its contact area and making its fixation more stable.

[0033] To facilitate feeding and discharging, a feeding hopper 1 is provided at the feeding end of the rubber conveying trough 8. The feeding hopper 1 is fixedly connected to the frame 3, and a filter screen 13 is fixedly connected to the inner side of the feeding hopper 1; a discharge port 7 is provided at the discharge end of the rubber conveying trough 8. By setting the filter screen 13 in the feeding hopper 1, larger particles in the material can be screened out.

[0034] In some embodiments, a cover plate 14 and a spray box 5 are fixedly connected above the frame 3, and a plurality of spray nozzles 4 are fixedly connected to the inner side of the spray box 5. By setting the cover plate 14 to prevent foreign objects from falling into the rubber conveying trough 8, setting the spray box 5 makes it more convenient to install the spray nozzles 4. At the same time, the distance between the spray nozzles 4 and the material can be controlled to avoid material contamination of the spray nozzles 4, resulting in blockage of the spray nozzles 4. After use, by spraying water into the rubber conveying trough 8 through the spray nozzles 4, it can be rinsed to reduce concrete residue.

[0035] In some embodiments, the spiral conveyor shaft 2 includes a rotating shaft 15 and spiral blades 16. The spiral blades 16 are fixedly connected to the outside of the rotating shaft 15. The inner diameter of the spiral blades 16 is greater than the outer diameter of the rotating shaft 15, and both ends of the rotating shaft 15 are rotatably connected to the frame 3 through bearings.

[0036] By setting the inner diameter of the spiral blades 16 to be smaller than the outer diameter of the rotating shaft 15, the material exceeding the width of the spiral surface of the spiral blades 16 will slide down from the gap between the rotating shaft 15 and the spiral blades 16, thereby controlling the material conveying volume and making the feeding amount more uniform.

[0037] In some embodiments, the support 10 includes a telescopic column 9 and a base 11. One end of the rubber conveying trough 8 is hinged to the base 11, and both ends of the telescopic column 9 are respectively hinged to the frame 3 and the base 11 for adjusting the inclination angle of the frame 3.

[0038] Specifically, the telescopic column 9 includes a first support column 19, a stud 23, and a second support column 25 arranged in parallel. One end of the stud 23 is rotatably connected to the first support column 19, and the other end of the stud 23 is threadedly connected to the second support column 25. Preferably, a nut 24 is fixedly connected inside the second support column 25, and the stud 23 is threadedly connected to the second support column 25 through the nut 24.

[0039] When adjusting the inclination angle of the adjusting frame 3, rotate the stud 23. Since the stud 23 is threadedly connected to the second support column 25, the length of the telescopic column 9 is changed, so as to achieve the purpose of adjusting the inclination angle of the adjusting frame 3.

[0040] Specifically, a support body 22 is fixedly connected to the outer side of one end of the stud 23 close to the first support column 19. A thrust ball bearing 20 is provided between the lower end surface of the first support column 19 and the upper end surface of the support body 22. By providing the thrust ball bearing 20, the friction force is reduced. At the same time, the support body 22 is fixedly supported on the outer side of the support body 22. The stud 23 is rotated through the rotating handle 21, and the cooperation of the two makes the height adjustment more labor-saving.

[0041] Track wheels 12 are rotatably connected to both sides of the base 11. By providing the track wheels 12, the movement is made more convenient.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
