Description

Technical Field

[0001] The utility model relates to the technical field of dust prevention for engineering vehicles, in particular to an automatic sunshade and dust prevention device for engineering vehicles. Background Art

[0002] In municipal engineering projects, when transporting goods such as sand and gravel, construction vehicles generally use tarpaulins to cover them to prevent the goods from spilling and dust from polluting the air during transportation. At present, most of the tarpaulins are laid manually, but the compartment area of ​​the construction vehicle is large, and it often requires multiple people to work together to complete this task, which is time-consuming and labor-intensive. The laying process needs to prevent sand and gravel and other items from falling and injuring people. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides an automatic sunshade and dustproof device for an engineering vehicle. In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0004] An automatic sunshade and dustproof device for an engineering vehicle is installed on the body of the engineering vehicle, and includes a sunshade, two sets of driving shafts, a driven shaft, a power unit, a connecting rod and a support rod. One end of the sunshade is fixed to the front end of the vehicle body, and the other end is fixed to the end of the support rod. The power unit is symmetrically fixed on both sides of the vehicle body. The power unit is rotatably connected to the driving shaft, which is rotatably installed at the front ends of both sides of the vehicle body, and the driven shaft is rotatably installed at the middle parts of both sides of the vehicle body. The driving shaft and the driven shaft are transmission-connected, and the connecting rod is respectively connected to the driven shaft and the support rod.

[0005] Furthermore, a belt is sleeved between the driving shaft and the driven shaft.

[0006] Furthermore, a chain is meshingly connected between the driving shaft and the driven shaft.

[0007] Furthermore, a cover rod is fixedly connected between the ends of the support rods, and the cover rod is fixedly connected to the awning.

[0008] Furthermore, a rear positioning buckle is fixedly connected to the top of the rear end of the vehicle body, and the cover rod is snap-connected with the rear positioning buckle.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] By starting the power device, the rotating shaft drives the supporting rod to rotate, thereby driving the cross bar connected to the tarpaulin to rotate from the front end of the vehicle body to the rear end of the vehicle body. After this process is completed, the tarpaulin is laid. If the tarpaulin needs to be opened, the opposite operation can be performed. This solves the traditional manual laying process of the tarpaulin, reduces the danger during the laying process, and saves manpower and material resources. Through the practical use of this device, the convenience of tarpaulin laying is improved, so that dust during construction is not affected by the bumps during transportation and overflow.

[0018] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figures 1 to 5 As shown, an embodiment of the utility model proposes an automatic sunshade and dustproof device for an engineering vehicle, which is installed on the body of the engineering vehicle, and includes a sunshade 1, two sets of driving shafts 2, a driven shaft 3, a power unit 4, a connecting rod 5 and a support rod 6. One end of the sunshade 1 is fixed to the front end of the vehicle body, and the other end is fixed to the end of the support rod 6. The power unit 4 is symmetrically fixed on both sides of the vehicle body. The power unit 4 is rotatably connected to the driving shaft 2, and the driving shaft 2 is rotatably installed at the front ends of both sides of the vehicle body. The driven shaft 3 is rotatably installed in the middle of both sides of the vehicle body. The driving shaft 2 and the driven shaft 3 are transmission-connected, and the connecting rod 5 is respectively connected to the driven shaft 3 and the support rod 6.

[0020] When the engineering vehicle is loaded with cargo, the awning 1 is opened, that is, the end of the support rod 6 is located at the front end of the vehicle body. After the cargo is loaded on the vehicle body, the power device 4, such as a motor, is started to drive the driving shaft 2 to rotate, and then drive the driven shaft 3 to rotate, thereby driving the support rod 6 fixedly connected to the driven shaft 3 to rotate, so that the end of the support rod 6 rotates from the front end of the vehicle body to the end of the vehicle body, so that the support rod 6 drives the awning 1 to cover the vehicle body and completes the laying of the vehicle body tarpaulin. If the awning 1 needs to be opened, the opposite operation can be performed.

[0021] In this embodiment, a belt is sleeved between the driving shaft 2 and the driven shaft 3, and a chain can also be meshedly connected between the driving shaft 2 and the driven shaft 3. The main purpose is to complete the transmission of the driven shaft 3.

[0022] More specifically, Figure 3 As shown, a cover rod 8 is fixedly connected between the ends of the support rods 6, and the cover rod 8 is fixedly connected to the sunshade awning 1. The cover rod 8 facilitates the unfolding of the sunshade awning 1 and the laying of the sunshade awning 1.

[0023] In another embodiment, Figure 3 and Figure 4 As shown, the rear end top of the vehicle body is fixedly connected with a rear positioning buckle 10, and the cover rod 8 is clamped with the rear positioning buckle 10. The rear positioning buckle 10 is convenient for positioning the cover rod 8, so that the awning 1 is laid more smoothly.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
