Description

Crushing suction cup and road sweeper Technical Field

[0001] The present invention relates to the technical field of road sweepers, and in particular to a crushing suction cup and a road sweeper. Technical Background

[0002] As one of the sanitation equipment, the road sweeper is a small cleaning equipment that integrates garbage cleaning, collection and transportation. It can be widely used in narrow areas such as non-motorized vehicle lanes, sidewalks, square parks, residential areas, etc., and has developed rapidly in China in recent years.

[0003] Due to environmental and weather conditions, especially in autumn, leaves and branches will fall onto the road. When using traditional road sweepers, leaves and branches will get stuck in the front of the suction cup and cannot enter the air duct. If they are too high from the ground, the suction will be weakened. Furthermore, leaves and branches entering the air duct are too large, which will cause the pipe to be blocked, affecting the suction power of the fan and the operation effect, and manual cleaning is necessary. After the garbage enters the trash can, it will fill up quickly due to its looseness. At this time, the frequency of garbage dumping needs to be increased, which greatly reduces the efficiency of the operation and increases transportation and labor costs. Some manufacturers use crushing fans, but if the pipe is already blocked before the garbage enters the fan, its effect will be minimal.

[0004] Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a crushing suction cup and a road sweeper to solve the technical problems of garbage jamming, pipe blockage and rapid garbage box filling in the current road sweeper in the above operating scenarios, thereby improving work efficiency.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0024] The present invention will be described in detail below with reference to the accompanying drawings:

[0025] As shown in Figures 1 to 3, the present invention provides a crushing suction cup, comprising a suction cup body 1, a power element 2, a bearing seat 3, a main shaft 4, a spacer 5, a cutter assembly 6, a bearing 7, an end cap 8, a front flap 9, a handle 10, a pull wire 11, a connecting rod 12, and an air intake 13. The cutter assembly 6 includes a cutter holder 61, a cutter 62, and a brush 63. A road sweeper equipped with the crushing suction cup includes a crushing suction cup 101, a trash container 102, and a fan assembly.

[0026] As shown in Figures 1 and 2, the suction cup body 1 is designed with a raised portion, which serves as the cavity of the crushing device. Its interior is a V-shaped structure. From left to right, the power element 2, bearing seat 3, bearing 7, spacer 5, cutter assembly 6, spacer 5, bearing 7, and end cover 8 are installed in sequence. The air suction port 13 is located at the rear of the cavity of the suction cup body 1. The bearing seat 3 and end cover 8 are equipped with bearings 7 and are arranged on both sides of the cavity of the suction cup body 1. The cutter assembly 6 is located inside the cavity and installed between the bearing seat 3 and end cover 8. The main shaft 4 runs through the suction cup body 1 from left to right, and is mounted on the bearing seat 3 at both ends via bearings 7. It is connected to the power element 2 and can drive the cutter assembly 6 to rotate. The main shaft 4 is connected to the bearing seat 3, bearing 7, spacer 5, cutter assembly 6, bearing 7, and end cover 8 from left to right. The power element 2 can drive the main shaft to rotate. The power element 2 is located on the outside of the suction cup body 1 and is mounted on the suction cup body 1 via the bearing seat 3. The front flap 9 is mounted at the front of the suction cup body 1, flexibly connected and capable of upward movement. A pull cord 11 is connected at its upper end to a handle 10 and at its lower end to a connecting rod 12. Connecting rod 12 is mounted on the suction cup body 1, with its front end attached to the outer end of the front flap 9. Handle 10 controls the opening and closing angle of the front flap 9 by tightening connecting rod 12 via the pull cord 11.

[0027] The tool assembly 6 includes a tool holder 61, a tool 62, and a brush 63. The tool 62 is made of wear-resistant material and is pinned to the tool holder 61, parallel to the vehicle's direction of travel. The brush 63 is bolted to the tool holder 61, perpendicular to the vehicle's direction of travel. If the tool 62 or brush 63 wears out due to prolonged operation, only the corresponding worn part needs to be replaced.

[0028] The connecting rod 12 is hingedly connected to an upper rod 121 and a lower rod 122 . The upper rod 121 is mounted on the suction cup body 1 , the front end of the lower rod 122 is mounted on the outer end of the front flap 9 , and the pull wire 11 is connected to the front end of the lower rod 122 .

[0029] When the crushing suction cup is operating, when the road garbage is regular small garbage, such as dust, paper scraps, stones, etc., the handle 10 is put down, the pull wire 11 is in a relaxed state, the front flap 9 is put down and in a closed state, the power element 2 and the tool assembly 6 are not running, and it is no different from a regular suction cup, and performs regular garbage suction and picking operations.

[0030] When the road garbage is large pieces of garbage such as leaves and branches, the handle 10 is pulled up, and the pull wire 11 is in a tensioned state, which controls the front flap 9 to be lifted up, and the opening and closing angle is controllable to ensure that large pieces of garbage can enter the suction cup body 1. At this time, the power element 2 is in operation, driving the tool assembly 6 to rotate. When large pieces of garbage enter the suction cup body, the V-shaped structure of the suction cup causes the garbage to gather in the middle cavity. When the garbage is too large to enter the air suction port 13, the garbage will stay in the suction cup body 1. At this time, the parallel-arranged tools 62 will shear and crush the garbage, turning the large pieces of garbage into small pieces. Then the vertically arranged brush 63 will sweep the crushed garbage backwards, and under the action of the rotating centrifugal force, the garbage will be swept up and sent into the air suction port 13, and then sucked into the garbage bin 102 through the air duct. The crushed garbage is small in size and is not easy to cause pipeline blockage. After entering the garbage bin, the garbage will directly settle and will not enter the fan.

[0031] As shown in FIG3 , the present invention provides a road sweeper equipped with the aforementioned crushing suction cup 101. The crushing suction cup 101 is mounted on the bottom of a connected vehicle. The air inlet of the fan assembly 103 is connected to the air intake 13 of the crushing suction cup 101, and the air duct of the fan assembly 103 is connected to the trash bin 102. When the fan assembly 103 is in operation, a negative pressure is created within the trash bin 102, which draws trash into the trash bin 102 through the crushing suction cup 101. The sucked-in trash settles inside, and only a small amount of dust and fine trash passes through the fan assembly and is then discharged from the vehicle.

[0032] The front baffle 9 of the crushing suction cup 101 can be opened and closed to adapt to different working conditions; when facing large pieces of garbage, they are crushed from the moment they enter the crushing suction cup 101, and the large pieces of garbage are turned into small pieces of garbage, which reduces the possibility of air duct blockage and reduces the labor intensity of manual cleaning; small pieces of garbage enter the garbage bin 102, and become more compact from loose, which increases the amount of garbage stored in the garbage bin 102, thereby reducing the frequency of garbage dumping and improving the work efficiency of operators.

[0033] The description of the present invention has been presented for purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the disclosed form. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles of the invention and its practical application and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as are suited for specific applications.
