Description

Technical Field

[0001] The present invention relates to the technical field of sweepers, and in particular to an automatic dumping device for a garbage collection box of an automatic driving sweeper. Background Art

[0002] Autonomous driving technology has been a popular technology in recent years. At present, autonomous driving technology is developing particularly rapidly in the field of sanitation, and more and more autonomous driving street sweepers are being tested on the road.

[0003] The self-driving sweeper is provided with a garbage collection box. When sweeping the garbage on the road, the garbage will be swept into the garbage collection box equipped on the self-driving sweeper. When the garbage collection box is full of garbage, it is necessary to dump the garbage in time and empty the garbage collection box. In this way, the self-driving sweeper can continue cleaning.

[0058] See also Figures 1 to 7 , the present invention provides an automatic dumping device for a garbage collection box of an automatic driving sweeper, comprising a rotating shaft assembly 3;

[0059] The shaft assembly 3 includes a shaft body 30, a first garbage collection box connecting arm 31 and a second garbage collection box connecting arm 32;

[0060] The left and right ends of the transversely distributed rotating shaft body 30 are respectively fixedly connected to the upper ends of the first garbage collection box connecting arm 31 and the second garbage collection box connecting arm 32;

[0061] The lower ends of the first garbage storage box connecting arm 31 and the second garbage storage box connecting arm 32 are hinged to the left and right ends of the garbage storage box 5 respectively;

[0062] The left and right end portions of the rotating shaft body 30 are respectively connected to a rotating shaft bearing 1;

[0063] Two rotating shaft bearings 1 are respectively mounted on a first rotating shaft support bracket 21 and a second rotating shaft support bracket 22 which are vertically distributed;

[0064] Among them, a heavy-duty push rod motor mounting bracket 9 for lifting is provided at the lower rear left end of the rotating shaft body 30;

[0065] The top of the heavy-duty push rod motor mounting bracket 9 for lifting is fixedly mounted with the lower end of a heavy-duty push rod motor 4 for lifting;

[0066] The push rod on the upper part of the heavy-duty push rod motor 4 for lifting is linked to the first garbage storage box connecting arm 31; the specific structure is as follows: the left and right sides of the upper part of the first garbage storage box connecting arm 31 are respectively fixedly connected with a push rod connecting plate 33 of the heavy-duty push rod motor for lifting; the push rod on the upper part of the heavy-duty push rod motor 4 for lifting is fixedly connected with two push rod connecting plates 33 of the heavy-duty push rod motor for lifting;

[0067] The right end of the shaft body 30 is hinged to one end of the first tilting lever 6;

[0068] The other end of the first tipping rotating rod 6 is hinged to one end of the second tipping rotating rod 8;

[0069] The other end of the second dumping rotating rod 8 is hinged to the right end of the garbage storage box 5;

[0070] Among them, a heavy-duty push rod motor mounting bracket 10 for dumping is fixedly mounted on the left side of the second rotating shaft supporting bracket 22;

[0071] The top of the heavy-duty push rod motor mounting bracket 10 for dumping is fixedly mounted with the lower end of a heavy-duty push rod motor 7 for dumping;

[0072] The push rod on the upper part of the heavy push rod motor 7 for dumping is fixedly connected with the first rotating rod 6 for dumping.

[0073] In the present invention, it should be noted that since the left and right ends of the garbage storage box 5 are respectively hinged to the lower ends of the first garbage storage box connecting arm 31 and the second garbage storage box connecting arm 32, the garbage storage box 5 can rotate freely around the lower ends of the first garbage storage box connecting arm 31 and the second garbage storage box connecting arm 32.

[0074] In specific implementation, a first garbage storage box rotating shaft 51 is respectively provided at the front end of the left and right side walls of the garbage storage box 5;

[0075] The garbage collection box 5 is hinged to the lower ends (having a reserved mounting hole) of the first garbage collection box connecting arm 31 and the second garbage collection box connecting arm 32 via the first garbage collection box rotating shaft 51 , so that the garbage collection box 5 can rotate around the first garbage collection box rotating shaft 51 .

[0076] In specific implementation, a second garbage storage box rotating shaft 52 is provided on the right side wall of the garbage storage box 5;

[0077] The second garbage storage box rotation axis 52 is closer to the middle position of the bottom of the right side wall of the garbage storage box 5 than the first garbage storage box rotation axis 51 .

[0078] The garbage storage box 5 is hinged to the other end (having a reserved mounting hole) of the second dumping rotating rod 8 via the second garbage storage box rotating shaft 52 , so that the garbage storage box 5 can rotate around the second garbage storage box rotating shaft 52 .

[0079] In specific implementation, in the original working state when the dumping is not started, see Figure 1 As shown, the second garbage storage box shaft 52 is located at the lower right of the first garbage storage box shaft 51. In the process of lifting the garbage storage box 5 by the push rod of the heavy push rod motor 4, the second garbage storage box shaft 52 can play a supporting role for the garbage storage box 5, see Figure 3 shown.

[0080] In specific implementation, the middle section and rear end of the garbage storage box 5 have garbage inlets and outlets 50 distributed laterally;

[0081] The garbage inlet and outlet 50 is inclined, and the height of the top thereof gradually decreases from the front to the back, that is, the height of the top at the front side is higher than the height of the top at the back side.

[0082] In the present invention, in a specific implementation, the two ends of the heavy-duty push rod motor 4 for lifting are fixed by axle pins, specifically: the lower end of the heavy-duty push rod motor 4 for lifting is fixed to the top of the heavy-duty push rod motor mounting bracket 9 by an axle pin; the push rod provided on the upper part of the heavy-duty push rod motor 4 for lifting is fixed to the push rod connecting plate 33 of the heavy-duty push rod motor for lifting in the rotating shaft assembly 3 by an axle pin.

[0083] In the present invention, in a specific implementation, the push rod provided on the upper part of the heavy push rod motor 7 for dumping is installed on the first dumping rotating rod 6 through an axle pin;

[0084] The lower end of the heavy-duty push rod motor 7 for dumping is fixed to the top of the heavy-duty push rod motor mounting bracket 10 for dumping through an axle pin.

[0085] In the present invention, in a specific implementation, the other end of the first tilting rotating rod 6 is hinged to one end of the second tilting rotating rod 8 through an axle pin.

[0086] It should be noted that, in the present invention, the first tilting rotating rod 6 and the second tilting rotating rod 8 can both rotate around the installation position.

[0087] In the present invention, in a specific implementation, the first dumping rotating rod 6 is located on the right side of the second garbage storage box connecting arm 32 .

[0088] In the present invention, in a specific implementation, the left and right end portions of the rotating shaft body 30 are respectively connected to the inner ring of a rotating shaft bearing 1;

[0089] The outer rings of the two rotating shaft bearings 1 are fixedly mounted on the first rotating shaft support bracket 21 and the second rotating shaft support bracket 22 respectively.

[0090] It should be noted that, for the present invention, the shaft body 30 on the shaft assembly 3 is fixed to the first shaft support bracket 21 and the second shaft support bracket 22 through the shaft bearing 1 and can rotate around the shaft bearing 1.

[0091] In the present invention, in a specific implementation, the bottom surface of the heavy-duty push rod motor mounting bracket 9 for lifting is located on the same plane as the bottom surfaces of the first rotating shaft supporting bracket 21 and the second rotating shaft supporting bracket 22, and the three are installed at the same height.

[0092] In the present invention, in a specific implementation, the first rotating shaft support bracket 21, the second rotating shaft support bracket 22 and the heavy-duty push rod motor mounting bracket 9 for lifting are respectively fixed on the chassis of the automatic driving sweeper.

[0093] For the present invention, when the garbage storage box 5 is lifted, the principle of keeping it horizontal is to adopt the principle that the two sides of the parallelogram are parallel to each other, such as Figure 7 Shown

[0094] The length L2 of the line connecting the center points of the two ends of the first dumping rod 6 (i.e., the swing arm) is equal to the length L1 of the line connecting the centers of the first garbage collection box shaft 51 and the second garbage collection box shaft 52, and they are parallel to each other. In terms of design, the four-point connecting line is a parallelogram. The heavy-duty push rod motor 7 for dumping is used to control whether the first dumping rod 6 (i.e., the swing arm) moves to control whether the garbage box is flipped. That is, the angle change of the first dumping rod 6 (i.e., the swing arm) drives the garbage collection box 5 to flip. The heavy-duty push rod motor 7 for dumping also plays the role of fixing the first dumping rod 6 (i.e., the swing arm) to prevent the garbage collection box 5 from flipping.

[0095] Therefore, for the present invention, the position of the garbage collection box 5 is adjusted by the mutual cooperation of the second garbage collection box shaft 52 and the first garbage collection box shaft 51, and the connection between the first dumping rotating rod 6 and the second dumping rotating rod 8 on the second garbage collection box shaft 52. For example, when the garbage collection box 5 is placed horizontally in the initial state, the second garbage collection box shaft 52 and the first garbage collection box shaft 51 suspend the garbage collection box 5 upward, and after the garbage collection box is raised, the second garbage collection box shaft 52 and the first garbage collection box shaft 51 support (lift) the garbage collection box 5, and when the garbage collection box 5 needs to be turned over or dumped, the garbage collection box 5 is pushed by pushing the second garbage collection box shaft 52, and the garbage collection box 5 rotates around the first garbage collection box shaft 51.

[0096] In order to more clearly understand the technical solution of the present invention, the working principle of the present invention is explained below.

[0097] For the present invention, the steps of automatically dumping garbage are as follows:

[0098] See also Figure 3 As shown, first, the push rod on the upper part of the heavy push rod motor 4 is extended outward, so that the garbage storage box 5 is lifted to a high point and remains stationary;

[0099] Then, the push rod of the heavy-duty push rod motor 7 for dumping is continuously controlled to be pushed out, and under the joint action of the first dumping rotating rod 6 and the second dumping rotating rod 8, the second garbage storage box rotating shaft 52 pushes the garbage storage box 5 to rotate around the first garbage storage box rotating shaft 51 thereon, so as to realize overturning, so that the garbage in the garbage storage box 5 can be dumped out. Figure 4 shown.

[0100] To sum up, compared with the prior art, the automatic dumping device of the garbage collection box of the autonomous driving sweeper provided by the present invention has a scientific structural design. By applying the present invention, when the garbage collection box on the autonomous driving sweeper is full of garbage and needs to be dumped, the present invention can automatically lift the garbage collection box and dump the garbage, which significantly reduces the degree of human intervention, making the garbage collection box more suitable for the field of autonomous driving technology of autonomous driving sweepers, and has great production practice significance.

[0101] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
