Description
Technical Field
[0001] The utility model relates to the technical field of silo cleaners, in particular to a revolution driving device for the revolving frame of a silo cleaner. Background Art
[0002] A silo cleaner is a bottom discharging device for cylindrical storage silos. At present, most of the bulk grain terminals or silos in grain depots in China have flat-bottom structures. However, because their silo bottoms are all flat surfaces, a considerable part of the grain cannot flow out by itself when discharging from the silo. If manual cleaning is used for the silo bottom, the efficiency is very low, and the dust concentration in the silo is very high during operation. Workers' health is seriously damaged during silo cleaning. In addition, if a dust explosion occurs, the lives of the silo cleaning personnel will be endangered. A silo cleaner is a special device dedicated to flat-bottom shallow cylindrical silos, steel plate silos and other bulk grain storage silos to clean the remaining materials at the bottom of the silo. It improves the silo cleaning efficiency and avoids the risk hazards of manual operation.
[0003] The revolution driving methods of the silo cleaner include intermediate driving and end driving. Among them, intermediate driving means driving the central rotary seat to rotate, and then driving the revolving frame to rotate, which requires a relatively large driving torque. End driving means driving the revolving frame to revolve by pushing it at the end through a driving cart, which requires a relatively small driving force.
[0004] The existing end driving mainly includes a vehicle frame. A traveling wheel is arranged on the vehicle frame. The traveling wheel is connected with a traveling driving device. The vehicle frame is provided with a force transmission frame matched with the revolving frame. A vehicle frame cover plate is arranged at the upper end of the vehicle frame. The traveling wheel is a rubber wheel installed on the side of the vehicle frame, and the traveling stability is poor. Content of the Utility Model
[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a revolution driving device for the revolving frame of a silo cleaner with high driving stability.
[0006] The utility model is realized by the following technical solutions: A revolution driving device for the revolving frame of a silo cleaner includes a vehicle frame. A traveling wheel is arranged on the vehicle frame. The traveling wheel is connected with a traveling driving device. The vehicle frame is provided with a force transmission frame matched with the revolving frame. A vehicle frame cover plate is arranged at the upper end of the vehicle frame. It is characterized in that the vehicle frame includes a framework. The traveling wheel is a crawler installed in the framework. A motor support frame is arranged on the side of the framework. The traveling driving device includes a driving motor arranged in the motor support frame.
[0007] Further, the framework surrounds the outside of the crawler. There is a counterweight cavity between the upper end of the framework and the vehicle frame cover plate, and a counterweight is arranged in the counterweight cavity.
[0008] Further, the driving motor is a variable-frequency permanent magnet motor, and a motor protection cover is arranged outside the motor support frame.
[0009] Furthermore, a cleaning device is also provided on the frame. The cleaning device includes a mounting bracket provided at the front end of the frame, and a cleaning plate inclined inward is provided on the mounting bracket.
[0010] The beneficial effects of the present utility model are as follows: The vehicle frame includes a frame, and a crawler is installed within the frame. The vehicle frame is driven to travel by the crawler, with high stability, capable of providing more stable ground gripping ability and complex terrain traveling ability, meeting the requirement of adapting to the changing situation of the bin bottom ground level after natural settlement of the bin bottom later, reducing the slipping phenomenon during traveling, and the frame and the vehicle frame cover plate isolate the crawler, thereby preventing materials from entering the crawler cavity. A motor support frame is installed on the side of the frame to protect and fix the motor, and the motor provides sufficient power for the crawler. The variable-frequency permanent magnet motor realizes constant torque output at different frequencies. Under this working condition, firstly, different speeds are provided to meet the variable-speed traveling of the revolution trolley; it adapts to different material layer heights and adjusts the traveling speed at any time. Secondly, it ensures a stable forward thrust output during the variable-speed traveling of the revolution trolley, adapts to the current situation of variable and uncertain material layer heights, and at the same time ensures the grain intake depth of the main frame auger, realizing a stable bin cleaning output yield.

[0018] Embodiment 1
[0019] As Figures 1-4 shown, a revolution drive device for the rotary rack of a stock clearing machine includes a central slewing base 1. The central slewing base is connected to the rotary rack. The rotary rack includes a connecting frame 2 and a screw conveyor 4 installed on the connecting frame. The revolution drive device for the rotary rack of the stock clearing machine is an end drive trolley 3, which includes a vehicle frame. A force transmission frame 304 matching the rotary rack is fixed on the vehicle frame. Specifically, it is connected to the connecting frame through the force transmission frame, and then the connecting frame is pushed to make a revolution motion. Travel wheels are installed on the vehicle frame. Specifically, the vehicle frame includes a frame 301 surrounded by steel plates, which further surrounds the outside of the crawler. The travel wheels are crawlers 302 installed inside the frame. The drive wheels of the crawlers are installed on the frame, reducing the outer contour size of the vehicle frame. In addition, it forms a protection for the side of the crawler, thereby preventing materials from entering the crawler cavity.
[0020] The travel wheels are connected to a travel drive device. Specifically, a motor support frame 307 is fixed on the side of the frame. A motor shield made of steel plates is wrapped outside the motor support frame to protect the motor and improve the explosion-proof effect at the same time. The travel drive device includes a drive motor installed inside the motor support frame. The drive motor selects a variable-frequency permanent magnet motor 308, which can provide a high output power. Cooperating with the crawler, it ensures the walking stability, and then promotes the stable revolution of the rotary rack. The variable-frequency permanent magnet motor is connected to the drive wheel of the crawler through a speed reducer 310. The variable-frequency permanent magnet motor realizes a constant torque output at different frequencies. In this working condition, firstly, it provides different speeds to meet the variable-speed travel of the revolution trolley; it adapts to different material layer heights and adjusts the travel speed at any time. Secondly, it ensures a stable forward thrust output under the condition of the variable-speed travel of the revolution trolley, adapts to the current situation of variable and uncertain material layer heights, and at the same time ensures the grain intake depth of the main frame screw conveyor, realizing a stable stock clearing output.
[0021] A vehicle frame cover plate 303 is installed at the upper end of the vehicle frame. There is a counterweight cavity between the upper end of the frame and the vehicle frame cover plate. A counterweight 309 is installed in the counterweight cavity. Specifically, a cross beam 310 is installed at the upper end of the frame to improve the stability of the frame and form a counterweight support platform at the same time. A plurality of limit blocks are welded on the cross beam, and a counterweight placement area is formed between the limit blocks to limit the counterweight. The counterweight does not need to be fixed additionally and can be limited in the counterweight placement area by its own weight. By adding the counterweight to increase the weight of the vehicle frame, the friction between the crawler and the silo is improved, ensuring the stable walking of the crawler.
[0022] A cleaning device is also installed on the frame. The cleaning device includes a mounting frame 306 installed at the front end of the frame. An inclined cleaning plate 305 is installed on the mounting frame. The inclined direction of the cleaning plate is inclined inward, so as to push the storage materials on the path inward, clean the running path of the crawler, and also gather materials towards the middle position, and then feed the materials to the central rotary seat through the auger, and finally convey them outside the silo.
[0023] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
