The embodiment of the invention provides a sweeper with a scraping device, which comprises: the bottom of the sweeper shell is provided with an opening; the driving device 200 is arranged on the sweeper shell and is positioned on one side of the opening; a bracket disposed corresponding to the opening and connected to the driving device 200; the spatula 110 is disposed at the bottom of the bracket, wherein the driving device 200 is configured to drive the bracket to move upward or downward relative to the opening, so that the bracket drives the spatula 110 to move upward or downward relative to the ground.

Referring to fig. 1 and 3, specifically, an opening is formed in the bottom of the sweeper housing, the support is of an integrated structure, the support is vertically arranged, the support is of a groove structure, the length of the supports on the left and right sides of the support is smaller than that of the supports on the front and rear sides, a spatula 110 is arranged at the bottom end of the support of the spatula 110, and the spatula 110 is arranged at the bottom of the left side wall of the support and fixedly connected with the support. A driving device 200 is provided on the left side of the spatula 110 support, and the driving device 200 is horizontally provided with the spatula 110 support. When the sweeper carries out cleaning, drive arrangement 200 drives the support upward movement, and the support is lifted up with spatula 110, and at drive arrangement 200 downstream, the support also downstream with spatula 110, and then spatula 110 can contact and shovel the rubbish that adheres to subaerial, reaches the clear purpose to stubborn rubbish.

In some embodiments of the invention, further comprising: the transmission device 300, one end of the transmission device 300 is connected with the driving device 200; a first sliding groove in the vertical direction is formed in the support; the free end of the transmission device 300 extends into the first sliding groove, and when the driving device 200 drives the free end of the transmission device 300 to move upwards, the free end of the transmission device 300 abuts against the top wall of the first sliding groove to drive the bracket to move upwards; when the driving device 200 drives the free end of the transmission device 300 to move downwards, the bracket moves downwards under the action of gravity.

Referring to fig. 1 and 2, in particular, a first sliding groove is formed in the bracket, the sliding groove is vertically arranged, and the sliding groove is a rectangular opening penetrating through the outer side wall of the bracket.

By allowing the support link 500 to be rotatably connected, the spatula 110 can be tilted to reciprocate while reciprocating up and down with respect to the spatula 110. The garbage can be shoveled by contact at different angles, and force is applied to the garbage from different angles, so that the garbage can be easily separated from the ground, and the cleaning efficiency of stubborn garbage adhered to the ground is improved.

In some embodiments of the present invention, there are two driving devices 200, and the two driving devices 200 are both disposed on the same side of the bracket, and are horizontally disposed along the outer edge of the bracket and respectively form a transmission connection with the bracket

Referring to fig. 4, in particular, two driving devices 200 are disposed at the outer side of the bracket, and at the left side region of the bracket. The two driving devices 200 are horizontally arranged with the bracket, and the driving devices 200 are both on the same side of the bracket. One of the driving devices 200 is disposed at the front end region of the bracket, the rotating shaft of the driving device 200 faces the front end region of the bracket, the other driving device 200 is disposed at the rear end region of the bracket, and the rotating shaft of the driving device 200 faces the rear end region of the bracket. Both drive units 200 are located at the same distance from the frame, and the axis of rotation near the front end region is located at the same distance from the foremost end of the frame as the axis of rotation near the rear end region is located at the rearmost end of the frame. The rotating shaft and the bracket are connected together through a connecting rod 300 to rotate. When the connecting rod 300 is moved, the forces applied to the regions of both sides of the bracket by rotation are uniformly balanced, so that each rotational movement is stably performed. At the same time, the simultaneous operation of the two drive assemblies 200 provides a more efficient movement of the carriage link 500 and carriage, which improves the cleaning efficiency of the spatula 110 during cleaning.

It should be noted that, when the bracket connecting rod 500 is rotatably connected to the housing of the sweeper and is connected to the connecting portion 130 in a penetrating manner, if the two driving devices 200 have different driving strokes, the two ends of the bracket can be driven to rotate/float up and down. Of course, this is only an embodiment and does not constitute the only limitation of the bracket's two ends being turned/floated up and down.

In some embodiments of the invention the spring is made of a material of high carbon steel.

During operation of the spatula 110 device, the operating driving device 200 continuously operates the spatula 110 device, the spatula 110 device is continuously subjected to a reaction force, and the spring is continuously subjected to a compression and pulling process. The spring made of high-carbon steel material can bear the impact of pressing and pulling for several times of accumulation due to the excellent plasticity, toughness and elasticity in the process, and the stability of the spring is kept. Meanwhile, the high-carbon steel material is easy to obtain, the production cost is low, and the manufacturing cost of the spatula 110 device can be reduced.

In some embodiments of the invention, the end of the spatula 110 facing the bottom surface is serrated.

The lower end of the spatula 110 is provided with a saw-toothed shape. Each of the teeth is parallel to the body of spatula 110 and each tooth is spaced a short distance from the other tooth. In the operation process of the scraper 110 device, the scraper 110 continuously contacts with garbage to carry out the scraping action, and the front end of the scraper 110 is provided with a saw-toothed shape, and the area of contact of the front end is reduced because the front end is the saw-toothed shape, so that the front end of the scraper 110 can be more fully contacted with the garbage attached to the ground to scrape, and the stubborn attached garbage can be easily scraped and removed.

In some embodiments of the invention, spatula 110 is made of a rubber material. In the device of the scraper blade 110, the scraper blade 110 is moved by the driving device 200, the scraper blade 110 can perform a scraping action within a predetermined range in cycles, and the scraper blade 110 continuously strikes the attached garbage on the ground while the scraper blade 110 is continuously subjected to a reaction force from the garbage. The spatula 110 made of rubber can well deal with the problem, the action of reaction force for scraping and removing contact garbage can be greatly reduced, the spatula 110 device can be used for more stably scraping, and the service life of the spatula 110 can be ensured by the spatula 110 made of rubber.

In some embodiments of the present invention, a dust inlet is also included, and the spatula 110 device is disposed at a forward end of the dust inlet.

Specifically, the sweeper is provided with a front wheel at the foremost end, a spatula 110 device is arranged behind the front wheel, a small distance is reserved between the front wheel and the spatula 110 device, a dust inlet is arranged behind the spatula 110 device, a rolling brush is connected to the dust inlet, and the spatula 110 device is arranged between the rolling brush and the front wheel. When the sweeper is used for sweeping, the front wheel of the sweeper runs forwards, when the sweeper passes through garbage attached to the floor, the scraper 110 at the rear position of the front wheel runs to scrape the attached garbage from the floor to be loosened, the sweeper further runs forwards, and when the sweeper passes through the dust inlet, the rolling brush sweeps the garbage and rolls the garbage into the dust inlet. The scraping shovel 110 device is arranged at the front end, can shovel garbage attached to the ground and then cleans the garbage by the rolling brush, so that the garbage cleaning device is more efficient than the rolling brush in the front cleaning process, and the cleaning efficiency of the sweeper is improved.
