Description

Technical Field

[0001] The invention belongs to the technical field of sweeping machines, and in particular relates to a sweeping machine with a roller brush. Background Art

[0002] like Figure 1 The sweeper shown in the figure is not shown in its entirety. The main brush 41 in the sweeper is responsible for sweeping a large area of ​​the road surface and throwing the garbage into the garbage bin 2 at the same time. First, the bristles of the main brush 41 must be sufficiently elastic to sweep up the garbage on the ground; then the bristles must be able to generate sufficient friction to ensure that the garbage can be squeezed into the space between the main brush 41 and the main brush cover 43; finally, the main brush 41 rotates rapidly, and at the entrance of the garbage bin 2, the garbage is separated from the main brush 41 and the main brush cover 43, performs centrifugal motion, and is thrown into the garbage bin. Due to the structural characteristics of the main brush 41 and the fixed rotation speed, the height at which the garbage is thrown is relatively fixed, resulting in the space of the garbage bin 2 not being fully utilized. Summary of the invention

[0003] The purpose of the present invention is to provide an electric sweeper to solve the technical problem of how to fully utilize the space of a garbage hopper to achieve the purpose of efficient cleaning.

[0004] The present invention provides a sweeping machine, comprising: a chassis; a garbage bucket, arranged on the chassis;

[0005] A first guide plate, whose outlet is arranged at the upper part of the entrance of the garbage hopper; a second guide plate, which guides the garbage into the garbage hopper; a main brush, which is arranged on the chassis and located at the lower part of the entrance of the garbage hopper, and the main brush transfers the swept garbage to the entrance of the first guide plate; at least one transfer brush transfers the garbage on the first guide plate to the second guide plate; an auxiliary brush, which sweeps the garbage on the second guide plate into the garbage hopper.

[0006] The inlet of the first material guide plate is located at the front side of the main brush.

[0007] The main brush, the conveying brush and the auxiliary brush are respectively provided with brush covers.

[0008] The main brush and the conveying brush rotate in the same direction.

[0009] The rotation direction of the auxiliary brush is the same as that of the conveying brush.

[0010] The rotation direction of the auxiliary brush is opposite to that of the conveying brush.

[0011] The main brush throws part of the swept garbage into the garbage bucket.

[0012] The outlet of the first material guide plate is connected to the inlet of the second material guide plate.

[0013] The beneficial effect of the patent of the present invention is that the main brush of the present invention can clean garbage in parallel, and the first conveying brush and the second conveying brush can lift the cleaned objects, thereby improving the cleaning cleanliness and reducing the power of the main brush motor. The main brush motor drives a plurality of transmission shafts to rotate through a transmission belt, has a high transmission efficiency, reduces the loss during the transmission process, and is more energy-efficient. At the same time, the sweeper provided by the present invention can sweep all the garbage swept by the main brush into the garbage hopper. During the cleaning process, part of the garbage swept by the main brush directly enters the lower part of the garbage hopper, and the other part is transmitted upward by the first conveying brush and the second conveying brush, and falls into the garbage can from the top of the garbage hopper through the auxiliary brush, making full use of the space of the garbage hopper.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0022] Figure 2 This is a schematic diagram of the structure of an embodiment of the sweeping machine of the present invention, and the figure does not show the entire structure of the sweeping machine. The chassis 1 is provided with wheels 3 for moving the sweeping machine, and the garbage hopper 2 is provided on the chassis, such as the rear end of the chassis, and the cleaning system 4 is located at the front end of the entrance 21 of the garbage hopper 2, which sweeps up the garbage on the ground and puts it into the garbage hopper 2. The cleaning system 4 includes a main brush 41, which is located at the lower part of the entrance 21 of the garbage hopper 2, and the main brush 41 is provided with a first brush cover 411, through which the main brush 41 can directly put part of the swept garbage into the garbage hopper 2. The front part of the main brush 41 is provided with an inlet 4311 of the first guide plate 431, and the main brush 41 throws the other part of the swept garbage into the inlet 4311 of the first guide plate 431. Since the inlet 4311 of the first guide plate 431 is arranged at the front side of the main brush 41, if there is fallen garbage, the main brush 41 can still sweep it up, thereby ensuring the cleaning quality. In addition, the inlet 4311 of the first guide plate 431 is very close to the main brush, and the garbage swept up by the main brush can be quickly and conveniently put into the inlet 4311 of the first guide plate 431, especially when garbage is accumulated in a unit area on the ground, the main brush throws the garbage out in time so that it can have enough capacity to sweep up the garbage. In the known technology, the main brush does not have time to clean up when garbage is accumulated, resulting in garbage left on the ground. The technical solution of the present invention effectively solves this problem. The cleaning system 4 is provided with a first conveying brush 421, an auxiliary brush 422 and a second guide plate 432. The brush wire of the first conveying brush 421 receives the garbage put into the inlet 4311 of the first guide plate 431 and sweeps it to the outlet 4312 of the first guide plate 431. The garbage on the outlet 4312 of the first guide plate 431 falls into the inlet 4321 of the second guide plate 432 under the action of gravity. The auxiliary brush 422 sweeps up the garbage from the inlet 4321 of the second guide plate 432 and puts it into the garbage hopper 2. The conveying brush 421 is provided with a second brush cover 4211, and the auxiliary brush 422 is provided with a third brush cover 4221. The third brush cover 4221 is used to prevent the garbage from being lost from the roller brush it protects. In the present invention, the second guide plate 432 is connected to the second brush cover 4211, and the first guide plate 431 is connected to the third brush cover 4221 to prevent the garbage from running out.

[0023] In this embodiment, the main brush 41 and the conveying brush 421 rotate counterclockwise, and the auxiliary brush 422 rotates clockwise.

[0024] The main brush 41 throws garbage from the lower part of the garbage hopper 2, and the auxiliary brush 422 throws garbage from the upper part of the garbage hopper 2, thereby ensuring that the space of the garbage hopper 2 can be fully utilized.

[0025] like Figure 3 FIG. 1 is a schematic diagram showing the structure of another embodiment of the present invention. Figure 2 The difference from the embodiment shown is that the embodiment further includes a second conveying brush 423, which sweeps the garbage on the first guide plate 431 to move it toward the outlet, thereby helping more garbage to fall near the auxiliary brush 422 and be more easily caught by the brush wires of the auxiliary brush 422; Figure 2 The difference from the embodiment shown is that in this embodiment, the outlet 4322 of the second guide plate 432 is bent upward, so that the garbage cleaned by the auxiliary brush 422 is thrown from the bend to the top of the garbage hopper 2 and then falls into the garbage hopper 2. This design can better ensure that the space of the garbage hopper 2 is fully utilized. The present invention only uses this embodiment to illustrate that the number of auxiliary brushes and conveying brushes is not limited to that shown in the figure, but is set according to actual use needs.

[0026] In the present invention, the main brush, auxiliary brush and transfer brush are all roller brushes. When garbage is transferred from one roller brush to another, it must be caught by the roller brush. It is required that the garbage flying out from the tangent direction of the roller brush just falls onto the brush wire of another roller brush. This requires adjusting the rotation speed of the roller brush. The higher the rotation speed of the roller brush, the easier it is to catch the garbage, or the closer the distance between the roller brushes, the easier it is to catch the garbage.

[0027] Preferably, the garbage cleaned by the main brush 41 flies out from the edge of the main brush 41 along the tangential direction and falls onto the brush wires of the first conveying brush 421 .

[0028] Preferably, based on the consideration of compact structure, the first conveying brush 421 and the second conveying brush 423 are tangent to each other.

[0029] and Figure 3 The embodiment shown is different in that Figure 4 In the illustrated embodiment, the outlet 4312 of the first guide plate 431 extends along the upper half of the auxiliary brush 422 toward the inlet 21 of the garbage hopper 2, forming a second guide plate 432. The garbage transferred to the second guide plate 432 is caught by the brush wires of the auxiliary brush 422 and is swept from the inlet 4321 of the second guide plate 432 to its outlet 4322 and dropped into the garbage hopper 2.

[0030] In this embodiment, the main brush 41 , the conveying brush 421 , and the auxiliary brush 422 all rotate counterclockwise.

[0031] Figure 5 for Figure 3 The embodiment diagram of the driving system 5 for driving the cleaning system 4 to move in the illustrated embodiment. The driving system 5 includes a motor 50, which is fixedly mounted on the chassis 1 and is used to provide power for the driving system 5 to move. The present invention preferably uses a motor, but other types of power equipment may also be used. The motor 50 drives the first pulley 51, the fourth pulley 54, the fifth pulley 55, and the sixth pulley 56 to rotate through the first transmission belt 501, the fifth pulley 55 drives the second pulley 52 to rotate through the second transmission belt 502, and the sixth pulley 56 drives the seventh pulley 57 to rotate. They are coaxial pulleys with different radii for changing the rotation speed, and the seventh pulley 57 drives the third pulley 53 to rotate through the third transmission belt 503, wherein the fifth pulley 55 is used for reverse rotation.

[0032] The belt pulley drives the rotating shaft at its center to move, and the roller brush is installed on the rotating shaft. The rotation of the rotating shaft drives the roller brush to rotate.

[0033] The sweeper provided by the present invention can sweep all the garbage swept by the main brush into the garbage hopper. During the cleaning process, since the entrance of the first guide plate is very close to the main brush, all the garbage swept by the main brush can quickly enter the first guide plate. When garbage accumulates in a unit area of ​​the ground, the main brush will throw the garbage into the first guide plate in time, so that it can have enough space to sweep the remaining garbage. In the known technology, the main brush must be used to throw the garbage into the garbage hopper. The garbage stays in the main brush for a long time, so that the main brush does not have enough space to sweep the garbage, and the garbage is easily missed. The technical solution of the present invention improves the garbage cleaning efficiency. In addition, the technical solution of the present invention does not require the main brush to throw the garbage over a long distance, thereby reducing the rotation speed of the main brush and reducing the power consumption and wear of the main brush.

[0034] In the description of the embodiments of the present invention, the front and back are described with the forward direction of the sweeper as the positive direction. The directions or positional relationships indicated by "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention.
