Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to a mobile unloading, dust collecting and sealing device for an unloading vehicle. Background Art

[0002] In the bulk material production and processing industry, especially in the production and transportation of dust-laden materials such as sand and gravel aggregates, the use of unloading trolleys is of significant value. Because they can deliver materials at multiple locations and on the move, unloading trolleys are key equipment in these scenarios.

[0003] According to application number 202023342727.8, a closed dust prevention device for a unloading trolley is disclosed, which can reduce dust during the unloading process of the unloading trolley and purify the workshop environment.

[0004] The following problems still exist in actual use:

[0005] The unloading trolley has the problem of difficulty in collecting dust in a closed manner during the mobile unloading process. In traditional practices, the escape of dust is reduced by completely closing the top of the receiving silo and retaining only the long strip feed port on the unloading path. This method cannot completely solve the problem. There is still an opening between the unloading port of the unloading trolley and the feed port of the receiving silo. Through these openings, dust can spread outward and cause air pollution. Utility Model Content

[0006] In response to the shortcomings of the existing technology, the utility model provides a mobile unloading dust collection and sealing device for an unloading vehicle, which has the advantages of keeping the unloading port and the feeding port of the receiving bin always in a closed state during the unloading process of the unloading vehicle, thereby improving the cleanliness of the working environment and solving the problems raised in the background technology.

[0007] The utility model provides the following technical solutions: a mobile unloading, dust collecting and sealing device for an unloading cart, comprising a unloading trolley, unloading chutes are provided on both side surfaces of the unloading trolley, a unloading port joint is provided at one end of the unloading chute, a receiving bin is provided on the bottom side of the unloading trolley, brackets are provided on both side surfaces of the receiving bin, pulleys are provided inside the brackets, feed ports are provided at both ends of the top side of the receiving bin, closed bags are provided at both ends of the top side of the receiving bin, a slit is provided on the top of the closed bag, guide rope clamps are provided at both ends of the slit, a dust-proof brush is provided on the inner wall of the slit, closing ropes are provided inside both sides of the slit, and a tensioning iron block is provided at one end of the closing rope.

[0008] Preferably, the unloading chute is installed on both sides of the unloading trolley, the unloading port joint is fixedly connected to one end of the unloading chute, the feeding port is opened on the top side of the receiving bin, the bottom of the closed bag is fixedly connected to the top of the unloading trolley, the slit is opened at the top of the closed bag, the guide rope clamp is installed at both ends of the slit, the dust-proof brush is fixedly connected to the inner wall of the slit, the closing rope is built into both sides of the slit, the receiving bin is arranged at the bottom end of the unloading trolley, the bracket is fixedly connected to one side surface of the receiving bin, the pulley is installed at the center position of the bracket, and the tensioning iron block is fixedly connected to one end of the closing rope.

[0009] Preferably, one end of the closing rope is fixed on the bracket, and the other end passes through the pulley and is hung with a tensioning iron block.

[0010] Preferably, the discharge chute and the discharge port joint are fixedly connected by a flange, one end of the discharge port joint passes through the seam inside the receiving bin, the closed bag wraps a part of the discharge port joint, and the material of the discharge port joint is wear-resistant material.

[0011] Preferably, the sealing bag is in the shape of a rectangular parallelepiped with a hollow bottom, and the bracket and the sealing bag are located on the same horizontal line.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The unloading vehicle is equipped with a mobile unloading dust collection and sealing device. When the discharge port joint moves, except for the discharge port joint position, the other positions of the sealing bag remain closed due to the tightening of the closing rope and the clamping action of the guide rope clamp, thereby achieving effective closed dust collection, significantly reducing dust escape, and improving the cleanliness of the working environment.

[0014] 2. The unloading vehicle is equipped with a mobile unloading dust collection and sealing device. When the slit is closed, dust can be prevented from escaping outwards by setting a dust-isolating brush. The dust-isolating brushes are intertwined to form an adsorption layer, and the dust is adhered to the bristles. In this way, even if the slit is not completely closed and there is a small gap, the dust cannot escape to the outside space. BRIEF DESCRIPTION OF THE DRAWINGS

Closing ropes 6 are provided inside both sides of the slit 13, and a tightening iron block 10 is provided at one end of the closing rope 6. The material of the closed bag 5 can be adjusted according to the properties of the dust and smoke, such as polyester fiber felt, polyester flannel, polyester needle felt, etc., to ensure that dust and smoke cannot penetrate the bag body and escape while maintaining its durability.

[0023] See also Figure 1 - Figure 5The bag 11 is fixedly connected to the top of the bag 12 and the bottom of the bag 13 is fixedly connected to the bag 12.

[0025] In the present invention, the working steps of the device are as follows:

[0026] The first step: when in use, the discharge port joint 3 is installed on the discharge chute 2 through the flange. The size of the discharge port joint 3 can be adjusted according to the different models of the discharge chute 2. The joint is sealed by the flange to prevent dust from escaping from the joint. When the discharge trolley 1 moves back and forth, the slits 13 on both sides of the discharge port joint 3 are clamped by the guide rope clamp 12, constraining it from opening laterally in the horizontal direction. Both ends of the slit 13 are constrained and cannot open in the horizontal direction and are in a closed state. The middle position is tightened by the action of the tensioning iron block 10, so that the closing rope 6 is tightened, so that all positions of the slit 13 are always in a closed state, ensuring that the discharge port joint 3 and the feed port 4 are always in an effectively closed state during the entire unloading process, which significantly reduces the escape of dust;

[0027] Step 2: When the slit 13 is closed, the dust-shielding brushes 11 installed on the inner side of the slit 13 are interlaced to form an adsorption layer. When the dust escapes outward, it will be blocked by the interlayer brushes and adhere to the bristles. In this way, even if the slit 13 is not completely closed and there is a small gap, the dust cannot escape to the outside space.
