[0020] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0021] In order to help those skilled in the art better understand the present invention, 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 embodiments described 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 making creative efforts should fall within the scope of protection of the present invention.

[0022] As described in the background technology, the grain storage cleaning vehicle; the existing cleaning vehicle uses a sweeping disc to clean the scattered grain, which generates a large amount of dust during the cleaning process. The dust causes pollution and brings the risk of explosion; the high-speed running sweeping brush causes some grain particles to be thrown far away from the cleaning vehicle, and the thoroughness of cleaning the grain particles needs to be further improved.

[0023] In order to solve this technical problem, the utility model provides a dust-suppressing and explosion-proof grain warehouse cleaning vehicle, which is used for cleaning scattered grain in the grain warehouse.

[0024] Specifically, please refer to Figure 1-3 The dust suppression and explosion-proof grain warehouse cleaning vehicle specifically includes: a cart body 1 and a scraping mechanism installed on the cart body 1, the scraping mechanism includes scraping components symmetrically arranged on both sides of the cart body 1 and a driving member that provides power for the two scraping components, the scraping assembly includes a first vertical shaft 2 rotatably installed on the cart body 1, a scraping member 20 and a torsion spring 3 installed on the first vertical shaft 2, the first vertical shaft 2 is elastically connected to the cart body 1 through the torsion spring 3, the driving member includes a driving motor 21 and a horizontal shaft 4 and a second vertical shaft 5 rotatably installed on the cart body 1, a bevel gear 6 is fixedly installed on the top of the second vertical shaft 5, a bevel wheel 7 is provided at both ends of the horizontal shaft 4, and a half-tooth portion meshing with the bevel gear 6 is provided on the bevel wheel 7, and the driving motor 21 provides power for the rotation of the horizontal shaft 4; the first vertical shaft 2 and the second vertical shaft 5 are synchronously transmitted; further, the driving motor 21 is connected to the horizontal shaft 4 through a transmission belt, and the first vertical shaft 2 and the second vertical shaft 5 are synchronously transmitted through a synchronous belt or a synchronous chain.

[0025] The dust suppression and explosion-proof grain storage cleaning vehicle provided by the utility model drives the horizontal shaft 4 to rotate through the driving motor 21, and the half-tooth portion on the bevel wheel 7 engages with the bevel gear 6 to drive the first vertical shaft 2 to rotate. After the transmission, the second vertical shaft 5 rotates and drives the scraping member 20 to rotate. The scraping member 20 pushes the scattered grain on the ground to the middle of the cart body 1. As the bevel wheel 7 rotates, the bevel gear 6 disengages from the upper half-tooth portion of the bevel wheel 7. Under the action of the torsion spring 3, the scraping member 20 is reset, and the concentrated scraping of the scattered grain on the ground is repeatedly achieved. The scraper 10 generates less dust in the process of scraping the grain, and while realizing the collection of grain, the generation of dust is reduced, the amount of grain particles escaping is effectively reduced, and the grain particle cleaning effect and efficiency are further improved.

[0026] A holding box 13 and a shoveling mechanism are installed on the cart body 1. The shoveling mechanism includes a shovel plate 14 and a belt conveyor assembly. A feed port is provided on the holding box 13. One end of the shovel plate 14 extends toward the ground, and the other end of the shovel plate 14 extends from the feed port on the holding box 13 into the holding box 13. The belt conveyor assembly includes two rollers 15 rotatably mounted on the cart body 1 and a conveyor belt 16 sleeved on the two rollers 15. The conveyor belt 16 is arranged parallel to the shovel plate 14, and the drive motor 21 is connected to one group of rollers 15 for transmission. Furthermore, a gap is left between the conveyor belt 16 and the shovel plate 14 to allow grain particles to pass through. The drive motor 21 is connected to one group of rollers 15 for transmission through a transmission belt.

[0027] The conveyor belt 16 is a plastic rubber belt; further, the thickness of the plastic rubber belt is at least 1 cm.

[0028] When the cart body 1 is moving, the shovel plate 14 scoops up the grain gathered by the two scraping parts 20, and the grain particles enter between the conveyor belt 16 and the shovel plate 14. The conveyor belt 16 presses the grain particles on the shovel plate 14 and sends the grain particles into the storage box 13, thereby realizing the boxing and collection of the gathered grain particles.

[0029] The conveyor belt 16 is made of a plastic rubber belt. When the conveyor belt 16 presses the grain particles, the plastic rubber belt deforms and can press grain particles of different particle sizes such as wheat and corn onto the shovel plate 14, which can meet the transmission needs of grain particles of multiple particle sizes and ensure that the gathered grain particles are smoothly collected into the storage box 13.

[0030] The rotating shaft 9 and the first vertical shaft 2 are both hollow shafts, and the interior of the rotating shaft 9 and the first vertical shaft 2 are connected. A vacuum cleaner 17 is fixedly installed on the receiving box 13, and the input end of the vacuum cleaner 17 is connected with the first vertical shaft 2 and the interior of the receiving box 13 respectively; further, the input end of the vacuum cleaner 17 is connected with the first vertical interior through a connecting pipe, and the connecting pipe is rotatably sealed with the first vertical shaft 2; the other output end of the vacuum cleaner 17 extends into the upper part of the receiving box 13.

[0031] Specifically, a battery pack 19 is installed on the cart body 1; the battery pack 19 provides kinetic energy for the drive motor 21 and the vacuum cleaner 17; the battery can provide electrical energy for the drive motor 21 and the vacuum cleaner 17 without the need for power supply from an external power source, thereby improving the mobility of the sweeper.

[0032] Specifically, the torque ring 11 is locked with the rotating shaft 9 by bolts; the torque ring 11 can be rotated to adjust its direction, thereby adaptively adjusting the tension of the tension spring 12, and appropriately compensating for the loss of torque caused by fatigue of the tension spring 12 after long-term use, so as to ensure that the scraper 10 is in good contact with the ground and ensure the smooth stacking of grain particles.

[0033] See also Figure 4 The scraping member 20 includes a mounting base 8 fixedly mounted on the first vertical shaft 2, a rotating shaft 9 rotatably mounted on the mounting base 8, and a tension reset assembly. A scraper 10 is fixedly mounted on the rotating shaft 9. The tension reset assembly includes a torsion ring 11 and a tension spring 12 sleeved on the rotating shaft 9. One end of the tension spring 12 is connected to the eccentric portion of the torsion ring 11, and the other end of the tension spring 12 is connected to the mounting base 8. When the scraper 10 rotates toward the middle of the cart body 1, the rotating shaft 9 drives the torsion ring 11 to rotate, and the tension spring 12 extends, so that the bottom of the scraper 10 always maintains close contact with the ground, ensuring that the grain particles are scraped away thoroughly. When the scraper 10 moves away from the middle of the cart body 1, the tension spring 12 contracts, the rotating shaft 9 rotates, and the friction between the scraper 10 and the ground is reduced, thereby improving the smoothness and thoroughness of the scraper 10 in scraping the scattered grain.

[0034] The rotating shaft 9 is provided with a plurality of suction nozzles 22 evenly distributed along the axis of the rotating shaft 9, and the suction nozzles 22 are symmetrically arranged on both sides of the rotating shaft 9. When the vacuum cleaner 17 is started, the slight dust generated by the scraper 10 is sucked into the interior of the rotating shaft 9 through the suction nozzles 22, and then sucked into the vacuum cleaner 17 through the first vertical shaft 2 and the connecting pipe. At the same time, the dust in the storage box 13 is also sucked into the vacuum cleaner 17 to prevent the dust in the storage box 13 from escaping. The slight dust generated by the scraper 10 is also processed, further reducing the dust flying around during the grain collection operation and reducing the dust explosion accident rate.

[0035] Specifically, the scraper 10 is provided with a bent scraper portion 18 bent toward the middle of the cart body 1; the bent scraper portion 18 can achieve close contact between the bottom of the scraper 10 and the ground during the process of the scraper 10 scraping the grain, and when the scraper 10 rotates away from the middle of the cart body 1, the bent scraper portion 18 can allow the remaining grain particles to pass through the bottom of the scraper 10, avoiding pushing the remaining grain particles away from the cart body 1 and improving the smoothness of the scraper 10's reset.

[0036] The use process of the dust suppression and explosion-proof grain storage cleaning vehicle provided by the present invention is as follows: the cart body 1 is pushed to move, and the horizontal shaft 4 is driven to rotate by the driving motor 21. The half-tooth portion on the bevel wheel 7 engages with the bevel gear 6 and drives the first vertical shaft 2 to rotate. After transmission, the second vertical shaft 5 rotates and drives the scraping member 20 to rotate. The scraping member 20 pushes the scattered grain on the ground to the middle of the cart body 1. As the bevel wheel 7 rotates, the bevel gear 6 disengages from the half-tooth portion on the bevel wheel 7. Under the action of the torsion spring 3, the scraping member 20 is reset, and this is repeated to achieve concentrated scraping of the scattered grain on the ground. The shovel plate 14 scoops up the grain particles concentrated in the middle of the cart body 1, and the grain particles enter between the conveyor belt 16 and the shovel plate 14. The conveyor belt 16 presses the grain particles on the shovel plate 14 and sends the grain particles into the holding box 13, completing the cleaning and collection of the grain particles.
