[0029] The present invention will be further described below with reference to the accompanying drawings through specific embodiments, but the present invention is not limited thereto. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.

[0030] Embodiment 1

[0031] As Figure 1 shown, a runway spraying machine described in this embodiment includes a mobile cart horizontally arranged with a bottom plate 1. A handle 3 for pushing the mobile cart to move is fixed on the right side of the bottom plate 1. A spraying component 5 for spraying is installed on the bottom plate 1. The spraying component 5 is an existing technology, that is, the common spraying machine structure mentioned in the background technology, mainly composed of a motor, a feeding device, a spray gun, and an atomization generating source.

[0032] The outside of the spraying component 5 is surrounded by an anti-dust component 4;

[0033] The anti-dust component 4 includes a first dust-proof housing 4.2, a second dust-proof housing 4.3, and a third dust-proof housing 4.4 arranged in sequence from inside to outside. The first dust-proof housing 4.2, the second dust-proof housing 4.3, and the third dust-proof housing 4.4 are all in an "L" - shaped structure as a whole, and their openings are all on the same side. The outer side wall of the second dust-proof housing 4.3 is attached to the inner side wall of the third dust-proof housing 4.4, and the outer side wall of the first dust-proof housing 4.2 is attached to the inner side wall of the second dust-proof housing 4.3. An adjusting cover plate 4.1 is buckled at the opening of the third dust-proof housing 4.4. The spraying component 5 is installed on the bottom plate 1 inside the first dust-proof housing 4.2; in this example, the opening is located at the front side. The structure of this paragraph can be seen in Figure 3 shown.

[0034] During transportation and use, the adjusting cover plate 4.1 is buckled at the opening of the third dust-proof housing 4.4. The first dust-proof housing 4.2, the second dust-proof housing 4.3, the third dust-proof housing 4.4, and the adjusting cover plate 4.1 as a whole form a box structure without a top surface and a bottom surface; under this design, other engineering tools can be placed in the empty space of this box as long as they do not affect the relevant components of the spraying component 5.

[0035] When in use for spraying, as Figure 4 shown, the lower end of the second dust-proof housing 4.3 is connected to the upper end of the first dust-proof housing 4.2 through a connecting member 4.5, the lower end of the third dust-proof housing 4.4 is connected to the upper end of the second dust-proof housing 4.3 through a connecting member 4.5, the adjusting cover plate 4.1 is buckled on the top of the third dust-proof housing 4.4, and the first dust-proof housing 4.2, the second dust-proof housing 4.3, the third dust-proof housing 4.4 and the adjusting cover plate 4.1 together form a box structure without a bottom surface and a front side surface. When in use, the rear side surface of the box is adjacent to the side that is about to be sprayed. In this way, most of the dust generated during spraying will stay on the outer surfaces of the adjusting cover plate 4.1, the first dust-proof housing 4.2, the second dust-proof housing 4.3 and the third dust-proof housing 4.4, preventing dust from entering the spraying assembly 5 to a certain extent; at the same time, since the box has no front side surface, it can also ensure the heat dissipation of the heating components (such as motors and other heating parts) in the spraying assembly 5 during operation.

[0036] The above-mentioned connecting member 4.5 can be completed by using existing connection methods such as screws or pasting.

[0037] Embodiment 2

[0038] As Figure 5 shown, this embodiment will further illustrate the technology. The handle 3 includes a first connecting rod 3.1 and a second connecting rod 3.3 that are spaced front and rear and are inclined with the left end lower and the right end higher. The lower end of the first connecting rod 3.1 is fixed to the front side of the bottom plate 1, and the lower end of the second connecting rod 3.3 is fixed to the rear side of the bottom plate 1. A horizontally arranged driving rod 3.2 is fixed between the upper ends of the first connecting rod 3.1 and the second connecting rod 3.3. The first connecting rod 3.1, the driving rod 3.2 and the second connecting rod 3.3 form a space for a worker to enter the lower half of the body. When the worker enters this space, the driving rod 3.2 is located at the worker's waist; a collision prevention component 2 is provided at the right end of the bottom plate 1 to prevent the worker's lower legs from directly colliding with the bottom plate 1.

[0039] In actual application, the driving rod 3.2 is height-adjustable. Specifically, connection holes are provided in the upper half sections of the first connecting rod 3.1 and the second connecting rod 3.3, and the driving rod 3.2 is fixed between the first connecting rod 3.1 and the second connecting rod 3.3 by screws passing through the connection holes.

[0040] The above-mentioned collision prevention component 2 can be made of a soft material such as a sponge in a strip structure.

[0041] As Figure 1, during the spraying operation of this embodiment, the whole machine can automatically follow the person, which can effectively reduce the length of the conveying pipe used during spraying, reduce the resistance suffered by the spraying material in the conveying pipe to a certain extent, and save a certain amount of energy consumption. This embodiment is very practical during runway spraying because the ground is relatively flat during runway spraying. During specific operation, the lower body of the worker enters the space formed by the first connecting rod 3.1, the driving rod 3.2, and the second connecting rod 3.3, and pulls the mobile trolley to the wall spraying area, then the spraying operation can start. During the spraying process, after the worker finishes spraying in one place, there is no need to pull it by hand, only need to gently pull it by exerting force with the waist. Under the design of the anti-collision and injury prevention component 2, it can effectively prevent the mobile trolley from continuing to move towards the worker due to inertia after the pulling stops. Without the anti-collision and injury prevention component 2 at this time, the worker's calf is very likely to collide with the bottom plate 1. With the anti-collision and injury prevention component 2, it can further protect the worker's calf. Generally, when pulling, the speed is not very fast, so its inertia is not very large.

[0042] Embodiment 3

[0043] As Figure 2 shown, this embodiment further illustrates the technology. The anti-collision and injury prevention component 2 includes an anti-collision strip 2.2 with an overall strip-shaped structure. The anti-collision strip 2.2 is located on the right side of the bottom plate 1. At least two sliding holes 2.6 are arranged at intervals in the front and back on the right side of the bottom plate 1. A sliding rod 2.5 that is in sliding fit with it is inserted into each sliding hole 2.6. One end of the sliding rod 2.5 passes through the sliding hole 2.6 and is fixed to the inner side of the anti-collision strip 2.2. A protective layer 2.1 is wrapped on the outer side of the anti-collision strip 2.2. The protective layer 2.1 can be made of soft materials in the prior art, such as sponge, etc.;

[0044] A spring 2.4 that separates the anti-collision strip 2.2 from the bottom plate 1 is sleeved on each sliding rod 2.5. One end of the spring 2.4 is fixed to the anti-collision strip 2.2, and the other end is fixed to the bottom plate 1. In the natural state of the spring 2.4, at least half of the sliding rod 2.5 is located in the sliding hole 2.6.

[0045] Under the design of this embodiment, combined with the relevant content of Embodiment 2, when the worker's calf contacts the protective layer 2.1, if the inertia of the bottom plate 1 is too large, at this time, the elastic force of the spring 2.4 will be overcome, and the distance between the anti-collision strip 2.2 and the bottom plate 1 will be shortened, so as to play a buffering role to a certain extent and further prevent the worker's calf from being injured.

[0046] Embodiment 4

[0047] As Figure 2 shown, this embodiment further illustrates the technology. The left end of the spring 2.4 is fixed to the bottom plate 1 through a spring seat 2.3. Specifically:

[0048] A through hole for the independent passage of the sliding rod 2.5 is provided in the spring seat 2.3. The left end of the spring seat 2.3 is fixed on the right end face of the spring seat 2.3, and the spring seat 2.3 is installed on the bottom plate 1 by screws. Under the design of this embodiment, the installation and maintenance of the anti-collision and anti-injury component 2 are facilitated.

[0049] Embodiment 5

[0050] As Figure 2 shown, this embodiment further illustrates the technology. The right end of the spring 2.4 is fixed to the bottom plate 1 through the spring seat 2.3. Specifically:

[0051] A through hole for the independent passage of the sliding rod 2.5 is provided in the spring seat 2.3. The right end of the spring seat 2.3 is fixed on the left end face of the spring seat 2.3, and the spring seat 2.3 is installed on the anti-collision strip 2.2 by screws. Its effect is the same as that of Embodiment Four, which is also to facilitate the installation and maintenance of the anti-collision and anti-injury component 2.

[0052] Embodiment 6

[0053] This embodiment further illustrates the technology. The adjustment cover plate 4.1 is located on the front side, and the connecting member 4.5 is four connecting rods 4.5.3; two in each group, and the two groups are distributed front and back, and the two connecting rods 4.5.3 in each group are distributed up and down;

[0054] For each connecting rod 4.5.3 on the front side, through holes are provided in the adjustment cover plate 4.1, the first dust-proof housing 4.2, the second dust-proof housing 4.3, and the third dust-proof housing 4.4. The right end of the connecting rod 4.5.3 enters from the through hole on the left side of the adjustment cover plate 4.1, sequentially passes through the through holes on the left side of the third dust-proof housing 4.4, the second dust-proof housing 4.3, and the first dust-proof housing 4.2, and then sequentially passes through the through holes on the right side of the first dust-proof housing 4.2, the second dust-proof housing 4.3, and the third dust-proof housing 4.4, and finally exits from the through hole on the right side of the adjustment cover plate 4.1. First blocking members for preventing the connecting rod 4.5.3 from slipping out of the through hole are provided at both ends of the connecting rod 4.5.3 outside the adjustment cover plate 4.1;

[0055] For each connecting rod 4.5.3 on the rear side, through holes are provided in the first dust-proof housing 4.2, the second dust-proof housing 4.3, and the third dust-proof housing 4.4. The right end of the connecting rod 4.5.3 enters from the through hole on the left side of the third dust-proof housing 4.4, sequentially passes through the through holes on the left side of the second dust-proof housing 4.3 and the first dust-proof housing 4.2, and then sequentially passes through the through holes on the right side of the first dust-proof housing 4.2 and the second dust-proof housing 4.3, and finally exits from the through hole on the right side of the third dust-proof housing 4.4. Second blocking members for preventing the connecting rod 4.5.3 from slipping out of the through hole are provided at both ends of the connecting rod 4.5.3 outside the third dust-proof housing 4.4.

[0056] When the connector 4.5 designed in this embodiment is in use, as Figure 4 shown, the first dust-proof housing 4.2, the second dust-proof housing 4.3 and the third dust-proof housing 4.4 have good stability and are also convenient to operate. The first blocking member and the second blocking member can adopt rubber sleeves that are in hard fit with the connecting rod 4.5.3, or nuts that are in threaded fit with the connecting rod 4.5.3.

[0057] Embodiment 7

A locking member 4.5.4 is arranged at the other end of the connecting rod 4.5.3.

[0059] When operating this embodiment, it is only necessary to clamp the dust-proof component 4 between the retaining ring 4.5.2 and the locking member 4.5.4, and the operation is convenient.

[0060] The locking member 4.5.4 can adopt a rubber sleeve that is in hard fit with the connecting rod 4.5.3, or a nut that is in threaded fit with the connecting rod 4.5.3.
