Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cleaning devices, in particular to a cleaning and dust suction mechanism for a granary cleaning vehicle. Background Art
[0002] There are many granaries for storing grains in large grain depots. After all the grains in the granary are out of the warehouse, a lot of impurities (dust) in the grains will remain on the ground of the granary. Before loading new grains, it is necessary to clean the dust and impurities on the granary ground. At present, manual cleaning is usually adopted. However, the area of the granary is very large. Taking a granary with a length of 50m and a width of 20m as an example, its bottom area is 1000 square meters. Manually cleaning a 1000-square-meter granary takes a long time and has low cleaning efficiency. Moreover, the granary is usually relatively enclosed, especially in summer, the environment in the granary is hot. Workers working in the granary for a long time are very likely to suffer from heat stroke. Summary of the Utility Model
[0003] In order to solve the above problems existing in the prior art, the utility model provides a cleaning and dust suction mechanism for a granary cleaning vehicle with stable structure, high cleaning efficiency and good dust removal effect.
[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0005] A cleaning and dust suction mechanism for a granary cleaning vehicle includes a connecting plate for connecting with the cleaning vehicle and a base plate arranged parallel to the lower side of the connecting plate. The base plate is vertically slidably connected with the connecting plate, and a lifting mechanism for driving the base plate to lift is arranged on the connecting plate; a plurality of rotating seats are arranged on the base plate, and a cleaning brush is rotatably arranged on each rotating seat. The cleaning brush includes a brush rod and a brush head fixed at the lower end of the brush rod. A driving mechanism for driving all the cleaning brushes to rotate is connected to the brush rod. Brush hairs are arranged on the brush head. An air suction seat is arranged on one side of the base plate. At least one air suction channel is arranged in each rotating seat, and the upper end of the air suction channel is connected with the air suction seat through an air suction pipe.
[0006] By adopting the above technical scheme: The connecting plate is connected with the cleaning vehicle, and the air suction seat is connected with the air suction fan on the cleaning vehicle. When the cleaning vehicle travels on the granary ground, the driving mechanism drives the cleaning brushes to rotate. The brush hairs of the cleaning brushes raise the dust on the granary ground, and at the same time, the air suction channels suck the raised dust away, so as to realize the rapid cleaning and dust suction operation at the bottom of the granary.
[0007] Preferably, a plurality of air suction channels are arranged on the rotating seat, and the air suction channels are uniformly distributed along the circumferential direction. A cover plate is arranged on the upper side of the base plate. An annular boss is arranged at the corresponding position of the bottom surface of the cover plate and the rotating seat. An annular groove communicated with the air suction channel is arranged on the bottom surface of the annular boss, and the air suction pipe is communicated with the annular groove.
[0008] Preferably, the cleaning brushes are arranged in two rows, front and back. A parallel support plate is provided on the upper side of the substrate. The upper end of the brush rod rotates through the support plate, and the driving mechanism is arranged on the support plate. The driving mechanism includes a worm gear fixed to the upper end of the brush rod, a worm arranged on the support plate, and a motor connected to one end of the worm. The worm is arranged between the two rows of worm gears and meshes with all the worm gears at the same time. When the motor drives the worm to rotate, all the worm gears rotate at the same time, and the rotation directions of the front and back rows of cleaning brushes are opposite.
[0009] Preferably, the brush head has a star structure. The bristles on the front row of cleaning brushes are configured as steel wire bristles, and the bristles on the back row of cleaning brushes are configured as nylon bristles. The steel wire bristles are wear-resistant and have a greater cleaning force, capable of removing stubborn impurities remaining on the ground. The nylon brush is more delicate and can raise finer dust, further improving the cleaning and dust suction effects.
[0010] Preferably, sliding seats are fixed at both ends of the substrate, and vertically distributed sliding rods are fixed at both ends of the connecting plate. The sliding rods pass through the sliding seats to form a sliding connection. The lifting mechanism includes an electric cylinder fixed to the connecting plate and a lifting bracket fixed to the support plate. The shaft end of the electric cylinder is connected to the lifting bracket. The electric cylinder drives the whole to lift, so as to adjust the contact state between the bristles and the ground to achieve the best cleaning effect.
[0011] Therefore, the utility model has the beneficial effects of stable structure, high cleaning efficiency, and good dust removal effect. Description of the Drawings
