Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the present invention, the use of directional words such as "upper, lower, left and right" generally means upper, lower, left and right as viewed with reference to the accompanying drawings; "inner and outer" refer to the inner and outer relative to the profile of the components themselves.
The invention provides a suction nozzle device which can perform the suction and picking operation of garbage. Although the suction nozzle device according to the present invention is mainly installed in a cleaning vehicle such as a sweeping machine for cleaning road debris, it is not limited to this process.
As shown in fig. 1, the suction nozzle device of the present invention includes a nozzle housing 3 having an open bottom, the nozzle housing 3 being in communication with a suction pipe 4 to form a negative pressure in the nozzle housing 3 by a blower 400 in communication with the suction pipe 4 to suck and pick up the road debris. The component plates of the suction nozzle housing 3 include a concentration suction nozzle plate 1 and a guide plate 2, and the concentration suction nozzle plate 1 is disposed facing the suction pipe 4 to make the suction force of the area facing the concentration suction nozzle plate 1 to be absorbed stronger. The guide plates 2 are respectively arranged on both sides of the concentration suction port plate 1, and form a garbage collection area 5 facing the concentration suction port plate. The guide plates 2 can be arranged symmetrically or asymmetrically depending on the mounting position of the suction nozzle device in the cleaning vehicle.
The width dimension of the waste collection area 5 gradually shrinks from the front of the suction nozzle housing 3 toward the concentration suction nozzle plate 1, and the height position of the lower edge of the concentration suction nozzle plate 1 is higher than the height position of the lower edge of the guide plate 2. Here, the "front and rear" directions are defined according to the forward direction of the vehicle, that is, the direction when the vehicle normally travels is "front" and the opposite direction is "rear". Therefore, by the above structure, the larger garbage can be guided by the guide plate 2 and enter the suction nozzle device from the concentrated suction nozzle plate 1 with the higher height position of the lower edge in a relatively concentrated manner, so that the garbage can be shunted, and the garbage with the larger size can enter the suction nozzle device.
Specifically, as shown in fig. 3, the arrow indicates the moving direction of the garbage under the suction action of the suction nozzle device, and here, the larger garbage refers to the garbage which can not pass through the gap between the guide plate 2 and the ground, such as sand, stone, paper bag, leaves, etc., and is indicated by a; and the smaller waste means waste which can enter from the gap between the guide plate 2 and the floor by the suction force generated by the negative pressure formed in the suction nozzle device, such as sand, etc., and is denoted by B.
It will be appreciated that in order to form the converging region 5, the distance between the front ends of the two side guide plates 2 is greater than the rear ends, i.e. the two side guide plates 2 approach each other gradually as they extend backwards, forming an angle therebetween. The guide plate 2 can be of various shapes, for example an arc-shaped plate or a straight plate as shown in fig. 3.
In addition, the angle and the gap between the guide plate 2 and the ground can be set appropriately according to the ground condition, the material of the guide plate 2, and the like. The guide plate 2 is preferably a rubber plate and can be formed at an angle to the ground, similarly to the below-described closing plate 12, and the lower edge is disposed toward the nozzle housing 3. In order to reduce the negative pressure loss in the nozzle housing 3, the guide plate 2 can be brought into contact without leaving a gap. In this case, when the suction nozzle device is operated forward, a gap sufficient for passing small garbage can be generated between the lower edge of the guide plate 2 and the floor surface by using the friction force between the lower edge of the guide plate 2 and the floor surface and the suction force generated by the negative pressure formed in the suction nozzle housing 3.
It will be readily appreciated that the gap can in fact vary to some extent according to the amount of small debris on the ground. That is, the more small waste on the floor (more sand grains, etc.), which means the higher roughness of the floor, the higher the frictional force for lifting up the guide plate 2, and therefore, providing the guide plate 2 as shown in fig. 2 can not only maximally maintain the negative pressure in the nozzle housing 3, but also generate a gap when contacting the small waste to achieve the purpose of sucking and picking up the waste, and has a good adaptability.
In the case of large garbage, since the height position of the lower edge of the concentration suction port plate 1 is higher than the height position of the lower edge of the guide plate 2 and the concentration suction port plate 1 faces the suction pipe 4, the suction force at the concentration suction port plate 1 is strong, so that the large garbage can easily enter the suction nozzle device. For convenience of expression, the height position herein refers to a height relative to the ground (reference level).
It is to be noted that the height position of the lower edge of the concentration suction port plate 1 higher than the height position of the lower edge of the guide plate 2 includes at least three states. One is that the centralized suction port plate 1 and the guide plate 2 are both fixed seal plates. At this time, when the height position of the lower edge of the guide plate 2 is 0 from the ground, the height position of the lower edge of the concentration suction plate 1 can be an arbitrary value greater than 0 from the ground at this time.
In another preferred embodiment of the present invention, the guide plate 2 is a fixed sealing plate 20, the collective suction port plate 1 is a movable sealing plate 10, and the movable sealing plate 10 is rotatably or elevatably attached to the front portion of the suction nozzle housing 3 so that the height position of the lower edge of the movable sealing plate 10 can be changed between the first height position and the second height position by turning the movable sealing plate 10 upside down or moving the movable sealing plate 10 upward. At this time, it is sufficient if either one of the first height position and the second height position is higher than the height position of the lower edge of the guide plate 2.
In addition, the centralized suction port plate 1 and the guide plate 2 are both provided with movable sealing plates. Both can be arranged to move separately or simultaneously. It is sufficient if the lowest position of the lower edge of the concentration suction port plate 1 is higher than the lowest position of the lower edge of the guide plate 2. Of course, the lowest position of the lower edge of the collective nozzle plate 1 may be made higher than the highest position of the lower edge of the guide plate 2 to accommodate the uneven change of the road surface while maintaining the negative pressure in the nozzle housing 3 as much as possible.
The movable closing plate 10 can be rotatably or elevationally provided on the nozzle housing 3 in various ways to change the height position of the lower edge of the movable closing plate 10. In the present invention, it is preferable that the movable sealing plate 10 is provided as shown in fig. 2 and 6, that is, the nozzle housing 3 is further provided with a telescopic driving mechanism 6 for driving the movable sealing plate 10 to be turned. Since the movable closure plate 10 changes the height position of the lower edge in an inverted manner, the lower edge can be raised relatively quickly. Further, the second height position described below can be easily adjusted by adjusting the distance of the telescopic drive mechanism 6 from the rotation fulcrum (i.e., the installation position of the holder 11) without changing the telescopic stroke of the telescopic drive mechanism 6 to be used. In other words, even if the second height position needs to be adjusted to suit different conditions, the telescopic driving mechanism 6 with a higher unit price can be replaced by changing the setting position of the support 11.
Specifically, the movable closing plate 10 is located at a first height position in the extended state of the telescopic driving mechanism 6 to close the front of the nozzle housing 3. That is, at the position shown by the dotted line in fig. 2, the height of the lower edge of the movable sealing plate 10 can be the same as the height of the lower edge of the fixed sealing plate 20, so that the pressure loss can be minimized and the small garbage can be reliably sucked and picked up. The movable closure plate 10 is flipped up in the retracted state of the telescopic drive mechanism 6 to raise the height position of the lower edge of the movable closure plate 10 to the second height position. That is, in the position shown by the solid line in fig. 2, the height of the lower edge of the movable sealing plate 10 is higher than the height of the lower edge of the fixed sealing plate 20, and the large garbage collected in the garbage collection area 5 can enter the nozzle housing 3 at this time, thereby completing the suction and collection of the large garbage.
The movable closing plate 10 has various structures, and in the embodiment shown in fig. 2 and 4, the movable closing plate 10 includes a closing stop plate 12 and a rotating plate 13, one end of the rotating plate 13 is rotatably supported on the nozzle housing 3, the other end of the rotating plate is fixed with the closing stop plate 12, and the rotating plate 13 is hinged to one end of the telescopic driving mechanism 6, so that the rotating plate 13 is driven by the telescopic driving mechanism 6 to rotate and further drive the closing stop plate 12 to turn. Specifically, the rotating plate 13 is provided with a support 11 and a mounting portion 16 for fixing the sealing plate 12, and one end of the telescopic driving mechanism 6 is hinged on the support 11. The closing plate 12 can be made of various materials, and preferably the same material as the guide plate 2, for example, rubber is used. The closing stop plate 12 is detachably fixed to the burring portion by a fastener such as a bolt for easy replacement or the like.
In order to make the rotating plate 13 parallel to the top surface of the nozzle housing in the extended state of the telescopic driving device, the sealing plate 12 is preferably inclined toward the inner cavity of the nozzle housing 3 and forms a predetermined angle with the plate surface of the rotating plate 13. In this case, when the telescopic driving means is extended, the closing stop plate 12 closes the front of the nozzle case and the rotating plate 13 is parallel to the top surface of the nozzle housing, which makes the appearance of the entire nozzle device more beautiful.
In addition, the rotating plate 13 may be mounted to the front of the nozzle housing body by a pivot shaft, and then the pivot shaft is driven by a cylinder, a motor, a hydraulic motor, or the like via a speed reducer to effect the turning of the rotating plate 13. Specifically, one end of the rotating plate 13 is hinged to a hinge seat 8 on the top surface of the nozzle housing 3, and a reset member 7 is provided on the hinge seat 8 to enable the rotating plate 13 to be quickly pressed down by the reset member 7 when the telescopic driving mechanism 6 is in the extended state, thereby reducing the time required for the return of the movable closing plate 10 to reduce the duration of pressure loss. The return element 7 can be an extension spring, a compression spring or another resilient pressing means, preferably a torsion spring.
In order to enhance the sealing performance in the nozzle housing 3 and reduce the pressure loss when large garbage is suctioned, it is preferable that the movable sealing plate 10 further include a side sealing plate 14. The side sealing plate 14 can separate the concentration suction port plate 1 and the guide plate to enhance the air tightness of the space from the suction pipe 4 to the concentration suction port plate 1. For example, the side sealing plates 14 are provided on both sides of the rotating plate 13 to form a garbage introduction chamber 15 with the sealing plate 12 and the rotating plate 13.
More preferably, the side sealing plate 14 is provided on the top surface of the nozzle housing 3 and protrudes upward at a position corresponding to the width of the rotating plate 13 to form a trash introduction cavity 15 with the sealing plate 12 and the rotating plate 13 when the movable sealing plate 10 is at the second height position. In this way, the side sealing plate 14 can define, together with the centralized suction port plate 1 and the top plate 60, a waste introduction cavity 15 for sucking and picking up larger waste when the movable closing plate 10 is at the second height position. And the side sealing plate 14 can effectively prevent pressure loss, and avoid that small fine sand garbage cannot be sucked and picked up due to pressure loss. Accordingly, when the movable closing plate 10 is located at the first height position, the side closing plate 14 does not interfere with the space of the nozzle housing 3 defined by the concentration nozzle plate 1, the guide plate 2, the first side plate 30, the second side plate 40, the transition plate 50, and the top plate 60.
Preferably, side sealing plate engaging portions 17 are formed on both sides of the movable sealing plate 10 to effectively seal the waste introducing cavity 15 formed by the movable sealing plate 10 being turned upward in cooperation with the side sealing plates 14.
In order to better guide the flow direction of the wind in the nozzle housing 3, it is preferable that the guide plate 2 is a fixed closing plate 20, and the nozzle housing 3 further includes first side plates 30 located outside the fixed closing plates 20, respectively, second side plates 40 located behind the first side plates 30 and parallel to the first side plates 30, a transition plate 50 connected between the first side plates 30 and the second side plates 40, and a top plate 60 covering the concentrated nozzle plate 1, the guide plate 2, the first side plates 30, the second side plates 40, and the transition plate 50.
Specifically, a movable closing plate 10 and a fixed closing plate 20 are connected to the front side of the top plate 60, and the fixed closing plate 20 is fixedly connected to the front side of the top plate 60, and preferably may be fixed to both sides of the movable closing plate 10 by rivets. However, the configuration of the nozzle housing 3 is not limited thereto, and the present invention is not limited thereto as long as the nozzle housing 3 includes the movable closing plate 10 and forms a nozzle housing having an open floor in a closed state of the movable closing plate 10.
Preferably, said top plate 60 is formed with a hole corresponding to the suction pipe 4, which can be connected to the hopper of the cleaning vehicle and is in communication with the fan of the cleaning vehicle.
In addition to the above-described technical means, as shown in fig. 2, the top plate 60 is provided with a gas auxiliary inlet 61. The arrows shown in fig. 2 indicate the flow direction of the air (wind). The auxiliary air inlet 61 blows reverse air into the nozzle housing 3 to effectively prevent the waste from being exposed from the rear of the nozzle device to cause secondary pollution.
The suction nozzle device is provided with rollers 70 for enabling the suction nozzle device to stably move on a road surface. In some specific working conditions, the form of the sliding groove and the sliding rail can be used, and the invention is not limited to the form of the sliding groove and the sliding rail, and the form of the sliding groove and the sliding rail is changed according to the application field, or the form of the sliding groove and the sliding rail is arranged according to the shape of the suction nozzle, so that the suction nozzle device can be evenly loaded and guided. As a preferred embodiment of the present invention, as shown in fig. 1, a roller 70 for moving the nozzle device is mounted on each of the first side plate 30 and the second side plate 40, so that it is possible to form a stable support for the nozzle housing 3.
The invention also provides a cleaning vehicle, which comprises a garbage can 500 and a suction nozzle device for sucking garbage into the garbage can, wherein the suction nozzle device is the suction nozzle device in the technical scheme, and the suction pipe 4 is communicated with the garbage can 500. Specifically, as shown in fig. 5, one end of the telescopic driving mechanism is mounted on the chassis 100, and the other end is connected to the support 11 of the suction nozzle device to turn the movable sealing plate. In addition, a pull rod 101 is connected to the chassis 100 to hold the nozzle device under the chassis.
The suction nozzle device of the cleaning vehicle adopts the suction nozzle device which is provided with the garbage collecting area 5, and has simple structure and practical function. The suction nozzle device is provided with two areas with different garbage suction and pickup gaps, and can effectively distribute and suck and pick up garbage. When the suction nozzle is used for sucking and picking small garbage, the suction nozzle has a good sealing cavity, so that the operation efficiency of the suction nozzle is higher; when the suction nozzle is used for sucking and picking up smaller garbage, the centralized suction nozzle plate formed into the movable sealing plate can be turned up to facilitate the garbage to enter, and the problem that the large garbage of the traditional suction nozzle is difficult to enter can be effectively solved. Accordingly, the cleaning vehicle mounted with the suction nozzle device of the present invention also has the above-described advantages. The cleaning vehicle can be a sweeping vehicle or a washing and sweeping vehicle with a sucking and sweeping function, and the like, and can achieve the effect of one vehicle with multiple purposes. Specifically, as shown in fig. 6, the suction nozzle device is disposed at the rear of the sweeping disk 200, and sucks the garbage into the garbage can 500 by the fan 400 driven by the sub-engine 300.
The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present invention within the technical idea of the present invention, and these simple modifications are within the protective scope of the present invention.

In addition, any combination of the various embodiments of the present invention is also possible, and the same should be considered as the disclosure of the present invention as long as it does not depart from the spirit of the present invention.
