Description

Technical Field

[0001] This invention relates to the field of road maintenance machinery technology, specifically to a median strip garbage recycling device. Background Technology

[0002] To avoid mutual interference, medians are often used to separate the two lanes of urban expressways or highways, and are usually planted with low shrubs. In practice, some dead branches and leaves, as well as road debris, accumulate at the base. Currently, manual cleaning of non-biodegradable debris at the base is commonly used, while decomposable debris such as leaves and branches is left to decompose on-site. However, in northern Chinese cities during autumn, there are many fallen leaves that accumulate on the road or in the median, affecting driving safety, especially on windy days when flying leaves can obstruct visibility and cause traffic accidents. Manual cleaning of leaves and debris in the median is slow, and the median is adjacent to fast overtaking lanes with high traffic speeds, making manual work dangerous. Therefore, a device capable of autonomously cleaning and recycling debris in the median should be developed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the existing technology and provide a median strip garbage recycling device. The device uses high-pressure gas to blow out the roots and leaves of the median strip, and uses a column assembly to interfere with and shake the trees in the median strip, causing the surface garbage to fall off. The blown garbage is collected from the other side. The entire device is mounted on a vehicle. When operating on the road, the device is a large target and is easily spotted and avoided by vehicles behind, reducing the safety risks of operation. This invention can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a centrally located waste recycling device, comprising a waste recycling assembly, a rocker arm assembly, and a column assembly;

[0005] The waste recycling assembly includes a negative pressure collection hopper that can be mounted on the bottom of a load vehicle, a brush roller at the inlet of the negative pressure collection hopper, and a negative pressure collection system connected to the negative pressure collection hopper.

[0006] The rocker arm assembly includes a horizontally arranged main arm with its end hinged to the top side of the load vehicle, and a telescopic rod that drives the main arm to swing in the horizontal plane.

[0007] The column assembly includes a columnar outer shell, an axial flow fan is integrated inside the outer shell and an air inlet is provided on the side wall, a filter element is provided at the air inlet, and an air guide nozzle is connected to the bottom of the outer shell, with the air outlet direction of the air guide nozzle opposite to the inlet direction of the negative pressure collection hopper.

[0008] As a preferred embodiment of the present invention, the column assembly includes a main shaft that axially penetrates the outer casing, and a main motor for driving the main shaft to rotate is provided at the end of the main shaft; a number of impellers are evenly spaced along the axis of the main shaft, and the outer casing shaft section corresponding to the impeller is closed, while the outer casing sidewall at the non-impeller position is provided with an air inlet.

[0009] As a preferred technical solution of the present invention, the air inlets on the side of the housing face the same direction, and an air collecting hood is provided outside the air inlet. A filter element bracket is provided inside the air collecting hood at a position corresponding to the impeller. The filter element and the filter element bracket are fixedly installed.

[0010] It also includes a vibration shaft arranged along the axis of the outer shell and rotatably mounted with the filter element support, wherein the vibration shaft has a built-in eccentric block and a drive motor is provided at its end;

[0011] The filter element has a high-pressure air pipe inside its outer shell space, and a high-pressure air nozzle is connected in series inside the high-pressure air pipe to blow air from the inside of the filter element.

[0012] As a preferred embodiment of the present invention, the filter element support has a tapered cross-section, and the width of its bottom end is consistent with the closed width of the outer shell corresponding to the impeller.

[0013] As a preferred embodiment of the present invention, the angle between the opening edge of the negative pressure collection bucket and the forward direction of the load vehicle is α, where 30°≤α≤45°;

[0014] The column assembly is always positioned in front of the load vehicle's trajectory relative to the waste recycling assembly.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The median strip garbage collection device adopts a vehicle-loaded form, integrating the entire collection device on the vehicle. During operation, the vehicle travels in the lane close to the median strip, the rocker arm assembly spans the top of the median strip, and the column assembly is placed on the opposite side of the median strip. As the vehicle moves forward, the high-speed airflow at the bottom of the column assembly blows the garbage at the root of the median strip out, and then it is quickly collected by the waste collection assembly at the bottom of the loaded vehicle. The whole process only affects the driving speed of one lane, and the overall target is large and easy to be seen by vehicles behind, with a low risk factor during operation.

[0016] Meanwhile, the distance between the pillar and the vehicle is adjustable, suitable for median strips of different widths. For shrub-like median strips, there are many dead leaves on the surface during the leaf-falling season. The pillar assembly can be used to touch the branches to promote the falling of the leaves, thus enabling one-time sweeping and collection.

[0017] Meanwhile, the central partition of the tree spacing acts as a dust collector, and there is a lot of dust on the surface of the leaves. When collecting garbage, the high-pressure airflow of the column assembly and the contact of the column assembly with the branches will cause dust to fly. The air inlet and filter on the side of the column assembly can adsorb this part of the dust and reduce the pollution to the environment.

[0018] Meanwhile, the high-pressure airflow inside the column assembly is generated by the synchronous rotation of multi-stage impellers, and its air inlet also has the effect of negative pressure dust removal. That is, the high-pressure generating unit is integrated inside the column assembly, which means that there is no need to install a dedicated high-pressure pipeline between the column assembly and the load vehicle. This helps to improve the convenience of the design and avoids the problem of substandard cleaning effect caused by poor sealing of high-pressure pipeline during operation.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-7 The present invention provides a technical solution: a centrally located waste recycling device, comprising a waste recycling assembly 1, a rocker arm assembly 2, and a column assembly 3;

[0031] Waste recycling assembly 1 includes a negative pressure collection hopper that can be mounted on the bottom of a load vehicle, a brush 101 located at the inlet of the negative pressure collection hopper, and a negative pressure collection system connected to the negative pressure collection hopper.

[0032] The negative pressure collection hopper and negative pressure collection system can use the existing collection system of the street garbage sweeping integrated garbage truck. They are also installed at the bottom of the vehicle and use negative pressure to absorb and recycle the garbage at the entrance of the negative pressure collection hopper.

[0033] The rocker arm assembly 2 includes a horizontally arranged main arm 201 with its end hinged to the top side of the load vehicle, and a telescopic rod 202 that drives the main arm 201 to swing in the horizontal plane.

[0034] See Figures 3-4 When designing the load-bearing vehicle, a groove is set on the top side of the vehicle body, and the end hinge seats of the boom 201 and the telescopic rod 202 are both set in the groove. When the telescopic rod 202 extends, the boom 201 can rotate forward until it is parallel to the vehicle body, thus completing the concealment of the boom 201 in the groove. The column assembly 3 can be hidden in the gap between the front of the vehicle and the box body. At this time, the overall width of the vehicle is the same as that of a normal vehicle body, and it will not cause any impact on traffic when not in operation.

[0035] During operation, the telescopic rod 202 shortens, causing the boom 201 to swing backward, which increases the distance between the column assembly 3 and the vehicle body. The swing angle is adjusted according to the width of the center strip and then fixed.

[0036] See Figures 5-7 The column assembly 3 includes a columnar outer shell 301. An axial flow fan is integrated inside the outer shell 301 and an air inlet is provided on the side wall. A filter element 305 is provided at the air inlet. An air guide nozzle 309 is connected to the bottom of the outer shell 301. The air outlet direction of the air guide nozzle 309 is opposite to the inlet direction of the negative pressure collection bucket.

[0037] A high-pressure airflow is generated by an axial flow fan and sprayed out from the bottom air guide nozzle 309, which directly acts on the root of the middle strip, blowing the garbage and dead leaves at that location to one side of the vehicle body until they are collected at the negative pressure collection hopper. Furthermore, the side air intake of the outer shell 301 can adsorb the dust generated during operation, thus avoiding air pollution.

[0038] See Figure 5 The column assembly 3 includes a main shaft 304 that axially penetrates the outer casing 301. A main motor 302 that drives the main shaft 304 to rotate is provided at the end of the main shaft 304. Several sets of impellers 303 are evenly spaced along the axis on the main shaft 304. The axial section of the outer casing 301 at the position corresponding to the impeller 303 is closed. An air inlet is provided on the side wall of the outer casing 301 at the position not corresponding to the impeller 303.

[0039] The synchronous action of the multi-stage impeller 303 ensures the flow rate of the high-pressure airflow and the force acting on the root of the middle strip. The special structural design of the outer shell 301 ensures that the side air inlets at different positions can have a certain negative pressure when the high-speed airflow flows inside, effectively adsorbing dust at different positions. The filter element 305 can filter dust and prevent particulate matter from damaging the impeller 303.

[0040] See Figures 5-7 The air inlets on the side of the outer casing 301 face the same direction, and an air collecting hood is provided outside the air inlet. Inside the air collecting hood, a filter element bracket 310 is provided at the position corresponding to the impeller 303. The filter element 305 is fixedly installed with the filter element bracket 310.

[0041] It also includes a vibration shaft 307 arranged along the axis of the housing 301 and rotatably mounted with the filter element support 310. The vibration shaft 307 has an eccentric block 306 built in and a drive motor 311 at its end.

[0042] The space inside the outer shell 301 of the filter element 305 is provided with a high-pressure air pipe 308, and a high-pressure air nozzle that can blow the filter element 305 from the inside is connected in series in the high-pressure air pipe 308.

[0043] When the filter element 305 is saturated with adsorption, the vibration shaft 307 can be driven to rotate by the drive motor 311, which in turn drives the eccentric block 306 to rotate, causing the filter element support 310 to vibrate, causing the dust inside the filter element 305 to fall off, and then being blown clean by the high-pressure air nozzle built into the housing 301, thus regenerating the filter element 305.

[0044] See Figure 5 The filter element support 310 has a tapered cross-section, and its bottom width is consistent with the closed width of the outer shell 301 corresponding to the impeller 303.

[0045] The filter element support 310 is designed in a conical shape, which helps to solve the whistling problem at the air inlet. At the same time, the eccentric block 306 can be built into the filter element support 310 to prevent it from being eroded by airflow.

[0046] See Figures 3-4 The angle between the opening edge of the negative pressure collection bucket and the forward direction of the loaded vehicle is... °≤α≤45°;

[0047] The pillar assembly 3 is always positioned in front of the load vehicle's trajectory compared to the waste recycling assembly 1;

[0048] The inclined negative pressure collection bucket allows the equipment to achieve a larger recovery range, meaning the boom 201 has a larger working angle, adapting to the use of more median strips of different widths.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
