Description

Technical Field

[0001] The utility model relates to the technical field of building construction devices, in particular to a dust reduction and material transportation device for construction. Background Art

[0002] During construction, for basements and garages in high-rise buildings, the garbage generated during the construction process is often temporarily piled up and then collected and transported by small transport vehicles. At present, the storage compartment of the transport vehicle is often just a rectangular box structure. During the bumpy transportation and the process of putting in the garbage, a lot of dust is often raised. In the relatively closed space around it, the dust floats in the air, causing the construction environment to deteriorate further and affecting the workers' work. Utility Model Content

[0003] The technical problem to be solved by the present invention is to address the above-mentioned technical deficiencies and provide a dust reduction and material transportation device for construction. The device can collect and filter the dust raised in the storage box during the process of dumping garbage through negative pressure adsorption, and can use a balance plate to shield the top of the storage box during transportation to reduce dust from floating out and effectively improve the quality of the construction environment.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention includes:

[0005] A frame is provided, a material storage box is provided above the frame, a ventilation cavity is provided in front of the material storage box, two air outlet channels are symmetrically provided in the ventilation cavity, and a filter assembly is provided inside the air outlet channel, a sleeve and an exhaust chamber connected to the ventilation cavity are provided in sequence at the top of the interior of the material storage box, and the exhaust chambers are symmetrically arranged on both sides of the material storage box, and a balance plate is provided on the sleeve.

[0006] Preferably, the rear of the material storage box is connected to the frame via a rotating shaft, and the front of the frame is provided with a thrust piece connected to the material storage box.

[0007] Preferably, the filter assembly includes a filter screen and a driving shaft; a plurality of the filter screens are sequentially installed in the air outlet channel along the height direction; the driving shaft passes through each filter screen in sequence, and a fan blade is provided above each filter screen.

[0008] Preferably, an air collecting duct is provided at the fan blades.

[0009] Preferably, an electric motor connected to a driving shaft is provided at the bottom of the air outlet channel.

[0010] Preferably, an exhaust chamber is provided at the bottom air outlet of the air outlet channel.

[0011] Preferably, a diverter plate is provided in the middle of the ventilation cavity.

[0012] Preferably, a plurality of ventilation holes are provided at equal intervals in the middle of the balance plate, and counterweights are provided on both sides of the balance plate.

[0013] Preferably, electromagnetic valves are provided at the air outlets of the sleeve and the air extraction chamber.

[0014] Preferably, an openable gate is provided at the rear of the storage box.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] 1. The negative pressure suction is generated by the filter assembly in the ventilation cavity, which enables the exhaust chamber to perform an exhaust operation on the top of the storage box. The dust raised during the dumping and transportation of garbage can be quickly absorbed, thereby preventing the dust from floating into the space outside the storage box, greatly improving the construction quality;

[0017] 2. When dumping garbage into the storage box, the weight of the garbage triggers the balance plate to flip to a certain extent, allowing the garbage to fall into the storage box. The balance plate then resets, which can reduce dust from floating out during transportation. The sleeve is connected to the inside of the ventilation chamber, which can also generate negative pressure adsorption to ensure that dust cannot float out when transporting or dumping garbage.

[0018] 3. The air outlet channels are arranged symmetrically, which can form a two-way filtering operation to ensure the filtering efficiency. In addition, the central area has a certain installation space for installing electrical equipment. The structural layout is reasonable and effectively improves the space utilization rate.

[0019] 4. By connecting the storage box to the frame through a rotating shaft and cooperating with the thrust piece, the storage box can be tilted, which facilitates the unloading operation and improves the unloading efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0029] Specific implementation method 1: Combination Figure 1-7 As shown, a dust reduction and material transport device for construction includes: a frame 1, a material storage box 2 is provided above the frame 1, a ventilation chamber 3 is provided in front of the material storage box 2, two air outlet channels 301 are symmetrically provided in the ventilation chamber 3, and a filter assembly 4 is provided inside the air outlet channel 301, a sleeve 201 and an air extraction chamber 202 connected to the ventilation chamber 3 are provided in sequence at the upper part of the material storage box 2, and the air extraction chamber 202 is symmetrically arranged on both sides of the material storage box 2, a balancing plate 5 is provided on the sleeve 201, and the balancing plate 5 can rotate relative to the sleeve 201;

[0030] By pulling the frame 1, the vehicle can be displaced in a relatively narrow area such as a basement or garage. When the stacked garbage needs to be transferred, the staff pours the garbage from the top of the storage box 2, and uses the gravity of the construction waste to overcome the rotation of the balance plate 5, so that the garbage falls into the storage box 2. Due to the height difference, the dust mixed in the garbage is easily raised. In the process of the dust being raised upward, the negative pressure suction force generated by the filter component 4 is used to suck the dust into the exhaust chamber 202 and the sleeve 201, and enter the air outlet channel 301 along the ventilation cavity 3 to achieve filtration and complete dust collection, thereby avoiding the raising of dust and effectively improving the working environment during the construction process. In addition, during the transportation process, the negative pressure adsorption state can be maintained, and the shielding of the balance plate 5 can be used to avoid the dust being raised and floating out due to bumps, which greatly solves the problem of environmental quality degradation caused by traditional construction.
