Description

Technical Field

[0001] The invention belongs to the technical field of floor washing and sweeping, and in particular relates to a floor washing and sweeping integrated vehicle. Background Art

[0002] With the development of cities and the increase in population, the use of roads is increasing, and the garbage and stains generated on the roads will affect the city's environment and the lives of citizens. Therefore, road cleaning has become very important.

[0003] The existing publication number is CN117248480A, which is a floor cleaning and sweeping vehicle. An auxiliary brush mechanism and a material-push wheel mechanism are provided on the bottom front side of the vehicle body. The auxiliary brush mechanism can move the garbage in front of the vehicle body to the middle of the vehicle body. As the vehicle body moves further, the garbage can be moved through the material-push wheel mechanism, and heavier solid garbage will be moved into the trash can.

[0004] In the above scheme, the auxiliary brush mechanism moves the garbage in front of the vehicle body to the middle of the vehicle body, but the guiding effect of the auxiliary brush mechanism is limited. The different weights of the materials will cause the garbage in front of the vehicle body to be moved to different positions, making it difficult to accurately move the garbage to the middle of the vehicle body; at the same time, when the material-pickup wheel mechanism moves the garbage, if the material-pickup wheel mechanism is too close to the ground, the material-pickup piece will constantly scratch the ground, thereby damaging the road surface. If the material-pickup piece is too far from the ground, it will affect the garbage collection effect. Therefore, the auxiliary brush mechanism and the material-pickup wheel mechanism in the above scheme are difficult to effectively collect the garbage. Summary of the invention

[0005] The object of the present invention is to provide a floor washing and sweeping vehicle, aiming to solve the technical problem that the auxiliary brush mechanism and the material-discharging wheel mechanism in the prior art are difficult to effectively collect garbage.

[0006] The present invention is implemented as follows: a floor washing and sweeping integrated vehicle comprises a vehicle body, the vehicle body is connected with a cleaning mechanism and a spray washing mechanism, the vehicle body is also fixedly connected with a support frame, both ends of the support frame are provided with a transmission mechanism, the two transmission mechanisms are arranged in a V shape, each transmission mechanism is rotatably connected with a plurality of push plates, all the push plates maintain a certain angle with the horizontal plane, and springs are connected between all the push plates and the transmission mechanisms, and driven by the transmission mechanism, all the push plates can continuously move toward a fixed track;

[0007] A transmission mechanism is provided on the upper side of the conveying mechanism, and the transmission mechanism is fixedly connected to the support frame. Under the guidance of the transmission mechanism, all push plates can push the garbage by swinging;

[0008] A guide assembly is provided in the middle of the two conveying mechanisms, and the guide assembly is rotatably connected to the support frame. When the support frame moves under the drive of the vehicle body, the guide assembly can push the garbage to both sides. A retractable electric push rod is provided between the guide assembly and the support frame.

[0009] The support frame is fixedly connected with a shell, the shell is facing the pushing direction of the garbage on the push plate, a feeding assembly is arranged in the shell, the feeding assembly can transfer the garbage into the shell, a pipeline is connected between the shell and the vehicle body, and the pipeline is connected to the air pump;

[0010] Control system: When garbage accumulates between two conveying mechanisms, the control system can speed up garbage collection by controlling the transmission mechanism, electric push rod and feeding assembly.

[0011] The conveying mechanism includes a roller, a conveyor belt and a driving motor;

[0012] One side of the support frame is rotatably connected to two rollers, and the two rollers are connected through a conveyor belt transmission. The housing of the drive motor is fixedly connected to the support frame, and the output shaft of the drive motor is fixedly connected to one of the rollers.

[0013] Further technical solution: the transmission mechanism includes an electric telescopic rod, a connecting plate and a stop rod;

[0014] The fixed end of the electric telescopic rod is fixedly connected to the support frame, the telescopic end of the electric telescopic rod is fixedly connected to the connecting plate, the connecting plate is fixedly connected to a plurality of blocking rods, and each blocking rod is arranged on the upper side of a push plate.

[0015] Further technical solution: The guide assembly includes a rotating plate and a guide plate. There are two rotating plates. Both rotating plates are rotatably connected to the support frame through elastic torsion springs, and each rotating plate is fixedly connected to multiple guide plates.

[0016] A further technical solution is that the two rotating plates are arranged in a V shape, and the V-shaped opening between the two rotating plates is opposite to the V-shaped opening between the two conveyor belts.

[0017] Further technical solution: The feeding assembly includes a dual-axis motor and a feeding plate, the dual-axis motor is fixedly connected to the inner wall of the shell, and the two output shafts of the dual-axis motor are fixedly connected to a plurality of feeding plates.

[0018] Further technical solution: the feeding plates are all arc-shaped.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. When the vehicle body moves forward, the garbage enters the middle of the support frame from the bottom of the feeding plate.

The push plate can be close to the ground to scoop up the garbage from the ground and push it upward obliquely, which increases the garbage collection effect; it avoids the problem that the feeding component directly contacts the ground and scratches the ground during garbage collection, resulting in poor collection effect and easy damage to the road surface;

[0024] 3. The electric push rod receives the signal and reciprocates and telescopes. The electric push rod pushes the rotating plate to swing, and the accumulated garbage is dispersed in different directions through the swing of the rotating plate, so that more push plates can push the garbage at the same time, avoiding the garbage being accumulated in one place and difficult to push effectively as the vehicle moves;

[0025] 4. The electric telescopic rod contracts, and the electric telescopic rod drives the blocking rod to move closer to the push plate. When the push plate passes through a blocking rod, the squeezing force of the blocking rod on the push plate increases, the rotation amplitude of the push plate increases, and the spring further contracts, so that the oblique thrust of the push plate on the garbage increases, and the ability to push heavier garbage is increased;

[0026] 5. The two conveyor belts are arranged in a V shape, so that the push plates on the two conveyor belts can push the garbage to the two ends of the feeding assembly when pushing the garbage, avoiding that all the push plates push the garbage to the middle of the feeding assembly, causing too much garbage to be concentrated in the middle of the feeding assembly, making it difficult to transport it in time. At the same time, the V-shaped arrangement between the two conveyor belts can collect the garbage between the two conveyor belts, and at the same time, all the push plates are spaced apart in the direction perpendicular to the travel of the vehicle body, increasing the cleaning range of all the push plates for the garbage.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0038] like Figure 1-Figure 8 As shown, a floor washing and sweeping integrated vehicle provided by the present invention comprises a vehicle body 1, the vehicle body 1 is connected with a cleaning mechanism and a spray washing mechanism, the vehicle body 1 is also fixedly connected with a support frame 2, both ends of the support frame 2 are provided with a transmission mechanism 3, the two transmission mechanisms 3 are arranged in a V shape, each transmission mechanism 3 is rotatably connected with a plurality of push plates 4, all the push plates 4 maintain a certain angle with the horizontal plane, and springs 10 are connected between all the push plates 4 and the transmission mechanisms 3, and driven by the transmission mechanisms 3, all the push plates 4 can continuously move toward a fixed track;

[0039] The upper side of the conveying mechanism 3 is provided with a transmission mechanism 5, and the transmission mechanism 5 is fixedly connected to the support frame 2. Under the guidance of the transmission mechanism 5, all the push plates 4 can push the garbage by swinging;

[0040] A guide assembly 7 is provided in the middle of the two conveying mechanisms 3, and the guide assembly 7 is rotatably connected to the support frame 2. When the support frame 2 moves under the drive of the vehicle body 1, the guide assembly 7 can push the garbage to both sides. A retractable electric push rod 6 is provided between the guide assembly 7 and the support frame 2;

[0041] The support frame 2 is fixedly connected with a housing 8, the housing 8 is facing the pushing direction of the garbage on the push plate 4, a feeding assembly 9 is arranged in the housing 8, the feeding assembly 9 can transfer the garbage to the housing 8, a pipeline is connected between the housing 8 and the vehicle body 1, and the pipeline is connected to the air pump;

[0042] Control system: When garbage accumulates between the two conveying mechanisms 3, the control system can speed up garbage collection by controlling the transmission mechanism 5, the electric push rod 6 and the feeding assembly 9.

[0043] In this embodiment, when the garbage enters the support frame 2, the guide assembly 7 guides the garbage in the middle to both sides. Driven by the conveying mechanism 3, all the push plates 4 can continuously move toward the fixed track. All the push plates 4 can push the garbage by swinging. The shell 8 is facing the pushing direction of the garbage on the push plates 4. The garbage is pushed into the shell 8 through the push plates 4, and then the garbage is sucked into the vehicle body 1 through the air pump.

[0044] During this process, when garbage accumulates between the two conveying mechanisms 3, the control system can speed up the garbage collection by controlling the transmission mechanism 5, the electric push rod 6 and the feeding assembly 9.

[0045] like Figure 6 As shown, a floor cleaning and sweeping integrated vehicle provided by the present invention, the conveying mechanism 3 includes a rotating roller 31, a conveyor belt 32 and a driving motor 33;

[0046] One side of the support frame 2 is rotatably connected to two rollers 31 , and the two rollers 31 are connected through a transmission belt 32 . The housing 8 of the drive motor 33 is fixedly connected to the support frame 2 , and the output shaft of the drive motor 33 is fixedly connected to one of the rollers 31 .

[0047] In this embodiment, the driving motor 33 is started, and the driving motor 33 drives one roller 31 to rotate, thereby driving the conveyor belt 32 to reciprocate between the two rollers, and the conveyor belt 32 drives all the push plates 4 to continuously move toward the fixed track.

[0048] like Figure 7 As shown, a floor cleaning and sweeping integrated vehicle provided by the present invention, the transmission mechanism 5 includes an electric telescopic rod 51, a connecting plate 52 and a blocking rod 53;

[0049] The fixed end of the electric telescopic rod 51 is fixedly connected to the support frame 2 , and the telescopic end of the electric telescopic rod 51 is fixedly connected to the connecting plate 52 . The connecting plate 52 is fixedly connected to a plurality of blocking rods 53 , and each blocking rod 53 is arranged on the upper side of a push plate 4 .

[0050] In this embodiment, when the vehicle body 1 moves forward and all the push plates 4 continue to move along the trajectory of the conveyor belt 32, at this time, one push plate 4 contacts the garbage and pushes the garbage to move synchronously, and then this push plate 4 contacts a blocking rod 53, and during the movement, it rotates under the limiting action of the blocking rod 53. At this time, the spring 10 connected to this push plate 4 elastically shrinks, and then the push plate 4 is separated from the blocking rod 53. Under the elastic action of the spring 10, this push plate 4 ejects the garbage obliquely upward to the feeding assembly 9.

[0051] like Figure 4 As shown, a floor cleaning and sweeping vehicle provided by the present invention is provided, wherein the guide assembly 7 includes a rotating plate 71 and a guide plate 72. There are two rotating plates 71, and both rotating plates 71 are rotatably connected to the support frame 2 through elastic torsion springs, and each rotating plate 71 is fixedly connected to multiple guide plates 72.

[0052] In this embodiment, when the vehicle body 1 is moving, the guide plate 72 is driven by the rotating plate 71 to push the garbage in the middle portion to both sides, so that the garbage falls into the pushing range of the pushing plate 4.

[0053] like Figure 4 As shown, a floor washing and sweeping integrated vehicle provided by the present invention is shown, wherein the two rotating plates 71 are arranged in a V-shape, and the V-shaped opening between the two rotating plates 71 is opposite to the V-shaped opening between the two conveyor belts 32;

[0054] The two conveyor belts 32 are arranged in a V shape, so that the push plates 4 on the two conveyor belts 32 can push the garbage to the two ends of the feeding assembly 9 when pushing the garbage, so as to avoid all the push plates 4 from pushing the garbage to the middle of the feeding assembly 9, which causes too much garbage to be concentrated in the middle of the feeding assembly 9 and is difficult to transport in time. At the same time, the V shape between the two conveyor belts 32 can collect the garbage between the two conveyor belts 32, and at the same time, all the push plates 4 are spaced apart in the direction perpendicular to the travel of the vehicle body 1, thereby increasing the cleaning range of all the push plates 4 for the garbage;

[0055] The two rotating plates 71 are arranged in a V-shape to guide the garbage and effectively separate and push the garbage to the rotating rollers 31 on both sides.

[0056] like Figure 8 As shown, a floor cleaning and sweeping vehicle provided by the present invention, the feeding assembly 9 includes a dual-axis motor 91 and a feeding plate 92, the dual-axis motor 91 is fixedly connected to the inner wall of the outer shell 8, and the two output shafts of the dual-axis motor 91 are fixedly connected to multiple feeding plates 92.

[0057] In this embodiment, when the dual-axis motor 91 is started, the dual-axis motor 91 drives the feeding plate 92 to rotate. Figure 3 In the embodiment, the feed plate 92 rotates in a clockwise direction;

[0058] When the vehicle body 1 moves forward, the feeding plate 92 can shovel the larger garbage into the support frame 2 after encountering the garbage. At the same time, the feeding plate 92 can compress the larger garbage to prevent the garbage from being too large to be scooped up by the push plate 4.

[0059] When the garbage enters the support frame 2, driven by the conveyor belt 32, the push plate 4 pushes the garbage inside the support frame 2 obliquely upward into the outer shell 8 by swinging. At this time, the feeding plate 92 can intercept the garbage and push it into the inner part of the outer shell 8 until the garbage is sucked into the vehicle body 1.

[0060] like Figure 8 As shown, a floor washing and sweeping vehicle provided by the present invention is shown, and the feeding plates 92 are all arc-shaped.

[0061] The present invention provides a floor washing and sweeping integrated vehicle, wherein the control system includes a pressure sensor, a data processor and a PLC controller;

[0062] The pressure sensor is arranged at the telescopic end of the electric push rod 6, and the pressure information of the pressure sensor is stored in the data processor. When the pressure value of the pressure sensor exceeds the preset threshold value in the data processor, the PLC controller receives the signal of the data processor and regulates the transmission mechanism 5, the electric push rod 6 and the feeding assembly 9.

[0063] Working principle:

[0064] When the vehicle body 1 moves forward, the garbage enters the middle of the support frame 2 from the bottom of the feeding plate 92, and the feeding plate 92 can shovel the larger garbage into the support frame 2 after encountering the garbage. At the same time, the feeding plate 92 can squeeze and compress the larger garbage to prevent the garbage from being too large to be scooped up by the push plate 4;

[0065] When all the push plates 4 continue to move along the track of the conveyor belt 32, at this time, one push plate 4 contacts the garbage and pushes the garbage to move synchronously, and then this push plate 4 contacts a blocking rod 53, and during the movement, it rotates under the limiting action of the blocking rod 53, at this time, the spring 10 connected to this push plate 4 elastically contracts, and then the push plate 4 is separated from the blocking rod 53, and under the elastic action of the spring 10, this push plate 4 obliquely ejects the garbage to the feeding assembly 9;

[0066] The push plate 4 can be close to the ground to scoop up the garbage from the ground and push it upward obliquely, thereby increasing the garbage collection effect; it avoids the problem that the feeding component 9 directly contacts the ground and scrapes the ground during garbage collection, resulting in poor collection effect and easy damage to the road surface;

[0067] When the garbage enters the support frame 2, the guide plate 72 is driven by the rotating plate 71 to push the garbage in the middle part to both sides, so that the garbage falls into the pushing range of the push plate 4. At this time, driven by the conveyor belt 32, the push plate 4 pushes the garbage inside the support frame 2 into the shell 8 by swinging obliquely upward. At this time, the feeding plate 92 can intercept the garbage and push it into the shell 8 until the garbage is sucked into the vehicle body 1;

[0068] During this process, when the vehicle body 1 moves too fast or a large amount of heavy garbage can be transferred to the housing 8 by the push plate 4, the garbage inside the support frame 2 is accumulated, and the garbage squeezes the rotating plate 71 and the guide plate 72. Under the action of the squeezing force, the rotating plate 71 rotates and squeezes the telescopic end of the electric push rod 6. When the pressure value of the pressure sensor at the telescopic end of the electric push rod 6 exceeds the preset threshold value in the data processor, the PLC controller receives the signal of the data processor and regulates the electric telescopic rod 51, the electric push rod 6 and the dual-axis motor 91.

[0069] The electric push rod 6 receives the signal and reciprocates and telescopes, and the electric push rod 6 pushes the rotating plate 71 to swing, and the accumulated garbage is dispersed to different directions through the swing of the rotating plate 71, so that more push plates 4 can push the garbage at the same time, avoiding that the garbage is accumulated in one place and difficult to be effectively pushed as the vehicle body 1 moves;

[0070] At the same time, the electric telescopic rod 51 contracts, and the electric telescopic rod 51 drives the blocking rod 53 to move closer to the push plate 4. When the push plate 4 passes through a blocking rod 53, the squeezing force of the blocking rod 53 on the push plate 4 increases, the rotation amplitude of the push plate 4 increases, and the spring 10 further contracts, so that the oblique thrust of the push plate 4 on the garbage increases, thereby increasing the pushing capacity of the heavier garbage.

[0071] The dual-axis motor 91 receives the signal and increases the rotation speed, thereby increasing the garbage collection efficiency.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0073] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
