Description

Technical Field

[0002] The suction nozzle is one of the important components of the leaf collection vehicle. When using the leaf collection vehicle to collect fallen leaves, the suction nozzle needs to be lowered to make it as close to the ground as possible, and the air in the trash bin on the vehicle body is sucked out by the fan on the vehicle body to form a negative pressure state, and then the suction nozzle connected to it through the pipeline is used to suck the scattered leaves on the ground into the trash bin, realizing the automatic collection of fallen leaves. The leaf collection operation is efficient and the cleaning is labor-saving. However, after use, the suction nozzle needs to be lifted up to make it as far away from the ground as possible so that the vehicle can travel normally and quickly on the road.

[0003] At present, the nozzle body on the fallen leaf collection vehicle has a small installation space due to the low chassis of the vehicle body. It is generally connected to the middle of the nozzle body by a wire rope to achieve its installation, and a cylinder is used to control its lifting. However, this layout method is only applicable to the nozzle body in the middle position of the vehicle chassis, and during the vehicle cleaning process, only the leaves at the bottom of the vehicle can be cleaned. Therefore, the width of the road surface cleaned at one time is small, which limits the improvement of its operating efficiency to a certain extent. To achieve synchronous cleaning of the ground on both sides of the vehicle, it is necessary to arrange and install the nozzle body on the side of the vehicle, but the side of the vehicle does not have the conditions to connect the nozzle body by wire rope lifting, and after forced installation, there will be defects such as nozzle lifting offset, asynchrony, and instability. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a side-mounted height-adjustable suction nozzle device for a fallen leaf collection vehicle, which is simple to install and lift and is stable after installation and can realize synchronous control.

[0006] As a preferred technical solution, the deformable support frame includes four deformable support arms, each of which is rotated and connected head to tail in sequence to form a parallelogram structure, the electric telescopic rod is obliquely arranged between two diagonals of the parallelogram structure, and both ends of the electric telescopic rod are rotatably assembled.

[0007] As a preferred technical solution, the two opposite deformable support arms are arranged vertically, one of the vertically arranged deformable support arms is provided with an arm assembly ear, the support mounting frame is provided with a mounting plate assembly ear used in conjunction with the arm assembly ear, and an assembly shaft is installed to limit the position of the arm assembly ear and the mounting plate assembly ear.

[0008] As a preferred technical solution, a damping rotation is arranged between the assembly shaft, the support arm assembly ear and the mounting plate assembly ear.

[0009] As an improvement to the above technical solution, a supporting crossbeam is fixedly welded to another vertically arranged deformable support arm, and the supporting crossbeam is fixedly connected to the side of the fallen leaf collection vehicle.

[0015] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0016] like Figure 1 and Figure 2 As shown, the height-adjustable suction nozzle device on the side of the leaf collection vehicle is installed on the side of the leaf collection vehicle, and is used to realize the installation of a structure for collecting leaves on the side of the leaf collection vehicle to improve its operating efficiency. Specifically, it includes a suction nozzle body 1 with an opening at the bottom end, and the top of the suction nozzle body 1 is fixedly connected to a leaf collection pipe 2. The suction nozzle body 1 is in the shape of a round sky and a square earth as a whole, that is, the bottom is rectangular and has a large collection area, and the top is formed with a small circular tubular structure that is convenient for connection with the leaf collection pipe 2. A support mounting frame 3 is fixedly connected to the suction nozzle body 1 to realize the installation and connection of the suction nozzle body 1.

[0017] A deformable support frame for adjusting the height of the suction nozzle body 1 is provided on one side of the support mounting frame 3, one side of the deformable support frame is rotatably connected to the support mounting frame 3, and the other side of the deformable support frame is fixedly installed on the side of the fallen leaf collection vehicle, and an electric telescopic rod 4 for driving the deformable support frame to deform is installed in the deformable support frame. The suction nozzle body 1 and the fallen leaf collection pipe 2 are connected to the side of the fallen leaf collection vehicle under the cooperation of the support mounting frame 3 and the deformable support frame, and generally the deformable support frame is connected to the side of the chassis of the fallen leaf collection vehicle.

[0018] The deformable support frame includes four deformable support arms 5, each of which is rotated and connected to form a parallelogram structure. The electric telescopic rod 4 is tilted between two diagonal angles of the parallelogram structure, and both ends of the electric telescopic rod 4 are rotated and assembled, and the telescopic end of the electric telescopic rod 4 is connected to the corner of the upper side of the deformable support frame and is away from the body of the fallen leaf collection vehicle, so that the electric telescopic rod 4 can be in a state of being tilted and stretched upward as a whole. The parallelogram structure formed by the four deformable support arms 5 has good deformation performance to cooperate with the extension and retraction of the electric telescopic rod 4, and realize the lifting and falling control of the nozzle body 1 during its extension and retraction.

[0019] In this embodiment, two of the opposite deformable support arms 5 are arranged vertically, and one of the vertically arranged deformable support arms 5 is provided with an arm assembly ear 6, and the support mounting frame 3 is provided with a mounting plate assembly ear 7 used in conjunction with the arm assembly ear 6. An assembly shaft 8 is installed through the arm assembly ear 6 and the mounting plate assembly ear 7. When in use, the nozzle body 1 is rotated outward to increase the area for collecting fallen leaves; when not in use, it is rotated inward to minimize the overall width of the fallen leaf collection vehicle to facilitate its travel. The damping rotation setting between the assembly shaft 8 and the arm assembly ear 6 and the mounting plate assembly ear 7 can be achieved by adding a damping washer on the periphery of the assembly shaft 8, so as to maintain the state of the nozzle body 1 after rotation without the aid of other components, making the entire structure simpler.

[0020] Specifically, when the leaf collection vehicle needs to put down the suction nozzle 1, the electric telescopic rod 4 is retracted, so that the suction nozzle 1 moves downward to reduce its height. After it is lowered to the working position, the suction nozzle 1 is rotated and swung out to collect the leaves; when the suction nozzle 1 needs to be lifted after the operation, the electric telescopic rod 4 is controlled to extend, drive the suction nozzle 1 to move upward to increase its height, and rotate the suction nozzle 1 back after it is lifted into place to prevent the suction nozzle 1 from colliding with speed bumps and the like during the transportation of the vehicle, thereby protecting the suction nozzle 1. When in use, the control end of the electric telescopic rod 4 is set in the cab of the leaf collection vehicle, and the lifting and lowering control of the suction nozzle 1 can be completed by one button, which is simple and convenient to operate.

[0021] A support beam 9 is fixedly welded on the other vertically arranged deformable support arm 5, and the support beam 9 is fixedly connected to the side of the fallen leaf collection vehicle, and the connection between the support beam 9 and the fallen leaf collection vehicle can be completed by welding, screwing, etc. The deformable support arm 5 and the support beam 9 are both channel steel structures with high strength and good support effect.

[0022] This embodiment has the following advantages:

[0023] 1. The four deformable support arms 5 actually form a four-link lifting mechanism. The electric telescopic rod 4 changes the state of the four-link mechanism, thereby achieving a change in the height in the vertical direction, and finally achieving the height adjustment of the nozzle body 1.

[0024] 2. The nozzle body 1 can be installed on vehicles with a relatively low chassis, and is particularly suitable for the sanitation installation requirements of electric three-wheeled and electric four-wheeled vehicles.

[0025] 3. The electric telescopic rod 4 is used for control, and the lifting and lowering movements are reliable, and the retention after lifting is good, and the falling phenomenon will not occur.

[0026] 4. The overall structure is simple, easy to control, stable and reliable, and has strong versatility.

[0027] The description of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.
