Description

Technical Field

[0001] The utility model relates to the technical field of road sanitation cleaning machinery, in particular to a tornado-type road garbage blowing and collecting vehicle which can clean leaf dust on the road at one time in the form of blowing air. Background Art

[0002] The streets and sidewalks are exposed to the open air all day long, so there are often many fallen leaves and dust scattered on the road surface. Therefore, city cleaners need to clean them regularly every day to keep the city clean and tidy.

[0003] In today's cleaning machinery and equipment, two disc brushes are generally arranged in parallel at the front end of the road sweeper. Through the rotation of the disc brushes, the vertically downward plastic brushes on the two disc brushes rotate relative to each other, sweeping the fallen leaves and dust on the ground touched by the plastic brushes into the travel route of the road sweeper, and the fallen leaves and dust on the travel route are sucked into the trash can of the road sweeper by the suction device on the road sweeper; the road sweeper has the defect of not cleaning the road cleanly, and the reasons are as follows: 1. The suction range of the suction device is large, and the air in all directions The air is sucked in at the same time and repel each other, and it is impossible to concentrate the limited attraction on the fallen leaves and dust in the route, so the fallen leaves and dust are missed; 2. The size of the two disc brushes is limited, and the relatively rotating plastic brushes cannot overlap each other, resulting in a reduction in the sweeping width and increased plastic brush loss; nor can the axes of the two disc brushes be too far apart, causing the range of fallen leaves and dust on the route of the road sweeper to become wider. The two disc brushes rotate 360 ​​degrees to bring in and out garbage, and cannot be concentrated in the middle of the road, which is not conducive to the suction equipment on the road sweeper to absorb. Summary of the invention

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a tornado-type road garbage blowing and collecting vehicle.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A tornado-type road garbage blowing and collecting vehicle comprises a machine platform, a functional wind shield, a blowing device, a dust collecting bag, a curved air duct, a handle, a universal wheel and an air guide pipe, wherein the universal wheel is fixed to the bottom of the machine platform, the handle is fixed to one side of the machine platform, and the blowing device is fixed to the machine platform; an air guide pipe with blocking plates fixed to both ends is fixed to the bottom surface of the machine platform, an opening is axially arranged at the bottom of the air guide pipe, and functional wind shields are fixed to both sides of the opening; the blowing device is arranged on one side of one end of the machine platform, and its air supply port passes through the bottom of the machine platform and is connected with an air inlet on one edge of the air guide pipe; a connected curved air duct is fixed on the other side of the other end of the air guide pipe away from the air inlet, and the curved air duct is connected to the dust collecting bag fixed to the opening at one end of the upper part of the machine platform;

[0007] The functional windshield is composed of a windshield of an air duct fixed to the bottom of the machine, an intermediate plate, and front and rear arc-shaped curved plates. The height of the outermost, vertically downward windshield is greater than the height of the universal wheel in contact with the ground, and the length is longer than the intermediate plate and the front and rear arc-shaped curved plates. The front arc-shaped curved plate is bent inward, and its lowest point after bending is flush with the ground in contact, and the lowest point of the rear arc-shaped curved plate after bending is higher than the ground in contact. The length of the vertically downward intermediate plate is between the windshield and the rear arc-shaped curved plate.

[0008] The air inlet on one side edge of the air guide pipe is arranged at the vertically downward edge of the air guide pipe;

[0009] The air outlet of the arc-shaped air duct fixedly arranged on the other side of the other end of the air guide pipe is located perpendicular to the axis of the air guide pipe and is arranged at the lowest edge of the air guide pipe;

[0010] The air inlet fixed on one side edge of the air guide pipe and the air outlet of the arc-shaped air duct are vertically combined to form a structure that generates a tornado-like cyclone;

[0011] The blowing device is more than one fan arranged in a line, and the air outlets thereof correspond to the air inlets on one side edge of the air guide pipe respectively;

[0012] The air inlet on one side edge of the air guide pipe is arranged at a diagonal position with the arc-shaped air duct fixed on the other side of the other end of the air guide pipe.

[0013] The utility model changes the ground to be cleaned from the original operation mode of sweeping on both sides and sucking in the middle to a horizontal tornado-style blowing operation, utilizes the horizontal arrangement of the open pipe to greatly increase the cleaning width, utilizes the blowing force (the air molecules behind the airflow at the air outlet push the air molecules in front to rush forward by inertia) greater than the suction force, utilizes the tornado rotation torque to overturn the garbage on the ground, overcomes the Bernoulli phenomenon that the pressure on the surface of the flat and soft garbage is greater than the pressure at the bottom when blown directly, and the garbage lies on the ground without moving. The airflow enters the pipe and spirals forward along the pipe wall due to the action of the centrifugal force, and forms a long wind curtain under the action of the arc-shaped curved plate, which blows toward the ground at an oblique angle to better overturn the garbage and dust on the ground, and strongly blows the garbage and fallen leaves in the opening provided axially at the bottom of the air guide pipe enclosed on the bottom of the machine platform, and collects them in the dust collecting bag. Compared with the existing disc brush cleaning, the road cleaning equipment such as negative pressure absorption and direct blowing has the advantages of large cleaning width, high cleanliness, low production cost, few accessories and light weight.

[0021] See attached Figures 1 to 6, a tornado-type road garbage blowing and collecting vehicle, comprising a machine 1, a functional wind shield 2, a blowing device 3, a dust bag 4, an arc-shaped air duct 5, a handle 6, a universal wheel 7 and an air guide pipe 8, the universal wheel 7 is fixed to the bottom of the machine 1, the handle 6 is fixed to one side of the machine 1, and the blowing device 3 is fixed on the machine 1; an air guide pipe 8 with blocking plates 83 fixed at both ends is fixed to the bottom surface of the machine 1, an opening 82 is axially provided at the bottom of the air guide pipe 8, and functional wind shields 2 are fixed on both sides of the opening 82; the blowing device 3 is arranged on one side of one end of the machine, and its air supply port passes through the bottom of the machine 1 and is connected with an air inlet 81 on one side edge of the air guide pipe 8, and a connected arc-shaped air duct 5 is fixed on the other side of the other end of the air guide pipe 8 away from the air inlet 81, and the arc-shaped air duct 5 is connected to the dust bag 4 fixed to the opening at one end of the upper part of the machine 1;

[0022] The functional windshield 2 is composed of a windshield 23 of the air duct fixed to the bottom of the machine, an intermediate plate 22, and front and rear arc-shaped curved plates 211, 21. The height of the outermost, vertically downward windshield 23 is greater than the height of the universal wheel 7 in contact with the ground, and the length is longer than the intermediate plate 22 and the front and rear arc-shaped curved plates 211, 21; the front arc-shaped curved plate 211 is bent inward, and its lowest point after bending is flush with the ground in contact, and the lowest point of the rear arc-shaped curved plate 21 after bending is higher than the ground in contact; the length of the vertically downward intermediate plate 22 is between the windshield 23 and the rear arc-shaped curved plate 21;

[0023] The air inlet 81 on one side edge of the air guide pipe 8 is arranged at the edge of the air guide pipe 8 vertically downward;

[0024] The air outlet of the arc-shaped air duct 5 fixedly arranged on the other side of the other end of the air duct 8 is located perpendicular to the axis of the air duct 8 and is located at the lowest edge of the air duct;

[0025] The air inlet 81 fixed on one side edge of the air guide pipe 8 and the air outlet of the arc-shaped air duct 5 are combined vertically to form a structure that generates a tornado-like cyclone;

[0026] The blowing device 3 is more than one fan arranged in a line, and the air outlets thereof correspond to the air inlet 81 on one side edge of the air guide pipe 8;

[0027] The air inlet 81 on one side edge of the air guide pipe 8 is arranged at a diagonal position with the arc-shaped air duct 5 fixed on the other side of the other end of the air guide pipe 8 .

[0028] When the utility model is used, the user pushes the handle 6 or other external power to move along the road to be cleaned. Since the height of the windshield 23 on the side away from the handle 6 is greater than the height of the universal wheel 7 contacting the ground, the friction of the ground causes the lower end of the windshield 23 to bend in the direction of the bending of the front arc-shaped curved plate 211, forming an entrance for accommodating dust and debris on the ground, while the lower end of the windshield 23 on the side close to the handle 6 is bent in the opposite direction of the bending of the rear arc-shaped curved plate 21, forming a shielding barrier; at the same time, the blowing device 3 is started, and since the air outlet of the blowing device 3 passes through The bottom of the machine 1 is connected to the air inlet 81 on the edge of one side of the air duct 8, the arc-shaped air duct 5 for guiding the outlet air is arranged at a diagonal position with the blowing device 3, the front and rear arc-shaped curved plates 211, 21 of the functional wind shield 2 on both sides form a cylindrical structure with the air duct 8, the air inlet 81 on the edge of one side of the air duct 8 and the air outlet of the arc-shaped air duct 5 are vertically combined with each other in space, so that the delivered wind forms a tornado-like blowing operation, which strongly blows the garbage and fallen leaves in the opening 82 axially provided at the bottom of the air duct 8 enclosed in the bottom surface of the machine, and collects them in the dust bag 4.

[0029] When the garbage entering the inner side of the front arc-shaped curved plate 211 of the functional windshield 2 on both sides and the ground and the bottom surface of the machine 1 is a hard object that is higher than the ground, since the front arc-shaped curved plate 211 is made of soft plastic material, its end will be lifted up by the hard object, and the lowest point of the rear arc-shaped curved plate 21 after bending is higher than the contacting ground, so it can be automatically moved out of the cleaned space smoothly without causing damage to the machine.

[0030] Of course, a baffle and a functional wind shield 2 can also be fixed at the bottom of the machine 1, and the same cleaning effect can be achieved by utilizing the curved structure of the functional wind shield 2. Therefore, this structure is also derived from the above structure and still falls within the scope of protection of the technical solution of the utility model.
