Description

Technical Field

[0001] The present invention relates to the technical field of highway maintenance equipment, and particularly to a weeding device for curb stones. Background Art

[0002] With the acceleration of the urbanization process, the roads in cities and towns have also changed greatly. The dusty dirt roads and sandy roads have disappeared, replaced by clean and tidy asphalt roads and cement pavements. Moreover, there are beautiful green belts on both sides of the roads. Green trees and flowers need soil. In order to separate the soil from the road surface, curb stones are widely used. However, no matter what method is used, it is impossible to ensure that no soil enters the gaps between adjacent curb stones for a long time. Tough weeds grow out from the gaps, making the whole road less beautiful.

[0003] The current weeding methods are manual pulling out or cutting with a knife, which requires a large amount of manpower, high cost, low efficiency, and the safety of weeding personnel cannot be guaranteed.

[0004] Figure 7 The shown curb stones are widely used on highways, which include a top surface 61, an inclined first side surface 62 and a vertical second side surface 63. Weeds grow between adjacent top surfaces, adjacent first side surfaces and adjacent second side surfaces. In the prior art, there is no relevant device for removing weeds in the gaps of curb stones. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a weeding device for curb stones. The first weeding component can remove weeds between adjacent top surfaces, the second weeding component can remove weeds between adjacent first side surfaces, and the third weeding component can remove weeds between adjacent second side surfaces. Since the first weeding component, the second weeding component and the third weeding component are all installed on the frame, only by moving the frame along the curb stone and making the first weeding component, the second weeding component and the third weeding component work simultaneously, the weeds in the gaps of the curb stone can be removed, and manual weeding is no longer required, with low cost, high efficiency and high safety factor.

[0006] To achieve the above purpose, the present invention provides a weeding device for curb stones, including a frame and a first weeding component, a second weeding component and a third weeding component installed on the frame. The first weeding component cooperates with the top surface of the curb stone, the second weeding component cooperates with the first side surface of the curb stone, and the third weeding component cooperates with the second side surface of the curb stone.

[0007] Further, the third weeding component cooperates with the bottom of the second side surface.

[0008] Furthermore, the first weed removal component includes a mounting plate which is connected to the frame. A guide wheel is installed below the mounting plate, and a motor is installed above the mounting plate. The power output shaft of the motor is connected to a rotating shaft. A steel wire is installed at the bottom end of the rotating shaft, and the bottom end of the rotating shaft is located between the bottom of the guide wheel and the mounting plate. The guide wheel of the first weed removal component cooperates with the top surface of the curb, and the rotating shaft of the first weed removal component is perpendicular to the top surface of the curb. The frame is connected to a vehicle.

[0009] Furthermore, the first weed removal component further includes a connecting plate and a first elastic member. The connecting plate is connected to the frame, and the connecting plate and the mounting plate are connected to each other through the first elastic member.

[0010] Furthermore, the second weed removal component has the same structure as the first weed removal component. The guide wheel of the second weed removal component cooperates with the first side surface of the curb, and the rotating shaft of the second weed removal component is perpendicular to the first side surface of the curb.

[0011] Furthermore, the structure of the third weed removal component is substantially the same as that of the first weed removal component. The difference is that the third weed removal component further includes a collision prevention wheel which is installed on the mounting plate of the third weed removal component. The guide wheel of the third weed removal component cooperates with the ground, the rotating shaft of the third weed removal component is parallel to the second side surface, and the outer circumferential surface of the collision prevention wheel cooperates with the second side surface.

[0012] Furthermore, the weed removal device for the curb further includes a connecting component. The connecting component includes a first hanging plate, a connecting frame and a second elastic member. The first hanging plate is connected to the right side of the vehicle, the connecting frame is connected to the frame. One side of the first hanging plate is provided with a first limiting plate, the front end of the first limiting plate is provided with a second limiting plate, and the rear end of the first limiting plate is provided with a support seat. One end of the connecting frame is rotatably connected to the support seat, and the other relative end of the connecting frame and the second limiting plate are connected through the second elastic member.

[0013] Furthermore, the frame is provided with a second hanging plate, and the second hanging plate and the connecting frame are in plug-in fit.

[0014] Furthermore, the number of the second elastic members is two. One second elastic member is located between the top end of the second limiting plate and the top end of the connecting frame, and the other second elastic member is located between the bottom end of the second limiting plate and the bottom end of the connecting frame.

[0015] Furthermore, the second elastic member is a damping spring.

[0016] The beneficial effects of the present invention are as follows: The first weeding component can remove the weeds between adjacent top surfaces, the second weeding component can remove the weeds between adjacent first side surfaces, and the third weeding component can remove the weeds between adjacent second side surfaces. Since the first weeding component, the second weeding component, and the third weeding component are all installed on the frame, only by moving the frame along the curbstone and making the first weeding component, the second weeding component, and the third weeding component work simultaneously, the weeds in the gaps of the curbstone can be removed, and there is no need for manual weeding anymore, which has low cost, high efficiency, and high safety factor.

[0030] In addition, the technical solutions between the various embodiments of the present application can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0031] The present invention provides a weeding device for curb stones.

[0032] A weeding device for curb stones includes a frame 2 and a first weeding component 3, a second weeding component 4, and a third weeding component 5 mounted on the frame 2. The first weeding component 3 cooperates with the top surface 61 of the curb stone, the second weeding component 4 cooperates with the first side surface 62 of the curb stone 6, and the third weeding component 5 cooperates with the second side surface 63 of the curb stone 6.

[0033] In the technical solution proposed in the present application, the first weeding component 3 can remove the weeds between adjacent top surfaces 61, the second weeding component 4 can remove the weeds between adjacent first side surfaces 62, and the third weeding component 5 can remove the weeds between adjacent second side surfaces 63. Since the first weeding component 3, the second weeding component 4, and the third weeding component 5 are all mounted on the frame 2, only by moving the frame 2 along the curb stone 6 and making the first weeding component 3, the second weeding component 4, and the third weeding component 5 work simultaneously, the weeds in the gaps of the curb stone 6 can be removed, and there is no need for manual weeding, which has low cost, high efficiency, and high safety factor.

[0034] The third weeding component 5 cooperates with the bottom of the second side surface 63. The main reason for the growth of weeds between the gaps of the curb stone 6 is birds. Birds leave grass seeds between the gaps through feces or other means. Since the second side surface 63 is vertical, the weeds in the gaps between adjacent second side surfaces 63 mainly grow at the bottom. Therefore, the cooperation of the third weeding component 5 with the bottom of the second side surface 63 can achieve a better weeding effect.

[0035] The first weeding assembly 3 includes a mounting plate 35. The mounting plate 35 is connected to the frame 2. A guide wheel 38 is installed below the mounting plate 35, and a motor 32 is installed above the mounting plate 35. The power output shaft of the motor 32 is connected to a rotating shaft 36. A steel wire 37 is installed at the bottom end of the rotating shaft 36. The bottom end of the rotating shaft 36 is located between the bottom of the guide wheel 38 and the mounting plate 35. The guide wheel 38 of the first weeding assembly 3 cooperates with the top surface 61 of the curb 6. The rotating shaft 36 of the first weeding assembly 3 is perpendicular to the top surface 61 of the curb 6. The frame 2 is connected to a vehicle. In a specific embodiment, a positioning hole (not labeled) is provided at the bottom end of the rotating shaft 36, and the steel wire 37 passes through the positioning hole and is locked. The motor 32 is a high-speed DC motor. A vehicle such as a light truck or a pickup truck is used as the carrying body. The number of guide wheels 38 is two, and the two guide wheels 38 are respectively arranged at opposite ends of the rotating shaft 36. The motor 32 is installed above the mounting plate 35 through a motor bracket 33.

[0036] During the high-speed rotation process, the steel wire 37 cuts weeds to achieve the purpose of weeding. As a flexible body, the steel wire 37 will not be damaged when it encounters foreign objects with high strength. When the steel wire 37 is damaged, it is also easy to replace. The guide wheel 38 contacts the surface of the curb 6 and serves as a working reference surface. During assembly, it facilitates the positioning of the positioning hole, so that the distance between the steel wire 37 and the curb 6 can be made close enough, which facilitates the cutting of low-lying weeds. The battery of the vehicle supplies energy to the high-speed DC motor. Since the vehicle continuously charges its battery during driving, there is no need to worry about the energy supply problem of the high-speed DC motor.

[0037] The first weeding assembly 3 further includes a connecting plate 31 and a first elastic member 34. The connecting plate 31 is connected to the frame 2, and the connecting plate 31 and the mounting plate 35 are connected by the first elastic member 34. In a specific embodiment, the first elastic member 34 is an ordinary spring, and the number of the first elastic members 34 is two. The two first elastic members 34 are arranged at opposite ends of the rotating shaft 36. The guide wheel 38, the mounting plate 35, the motor bracket 33, the motor 32, the rotating shaft 36 and the steel wire 37 are used as an integral structure, and the first elastic member 34 is assembled between them and the connecting plate 31, which can buffer the impact brought by the curb 6.

[0038] The second weeding assembly 4 has the same structure as the first weeding assembly 3. The guide wheel 38 of the second weeding assembly 4 cooperates with the first side surface 62 of the curb 6, and the rotating shaft of the second weeding assembly 4 is perpendicular to the first side surface 62 of the curb 6.

[0039] The structure of the third weeding component 5 is substantially the same as that of the first weeding component 3, except that the third weeding component 5 further includes a collision avoidance wheel 51. The collision avoidance wheel 51 is installed on the mounting plate of the third weeding component 5. The guide wheel of the third weeding component 5 cooperates with the ground. The rotating shaft of the third weeding component 5 is parallel to the second side surface 63, and the outer circumferential surface of the collision avoidance wheel 51 cooperates with the second side surface 63.

[0040] To facilitate the installation of the first weeding component 3, the second weeding component 4 and the third weeding component 5, the frame 2 is provided with a first mounting portion 23, a second mounting portion 24 and a third mounting portion 25. The connecting plate 31 of the first weeding component 3 is connected to the first mounting portion 23. The connecting plate of the second weeding component 4 is connected to the second mounting portion 24. The connecting plate of the third weeding component 5 is connected to the third mounting portion 25.

[0041] During the actual use of the present invention, the driver will use the auxiliary line of the emergency lane on the highway as a reference to prevent the vehicle from deviating. When the steering wheel is accidentally turned a little to the left, the driver will use the auxiliary line of the emergency lane as a reference to correct the steering wheel. To prevent the first weeding component 3, the second weeding component 4 and the third weeding component 5 from malfunctioning during the process from accidentally turning the steering wheel to the left to the correction completion, the roadside stone weeding device further includes a connecting component 1. The connecting component 1 includes a first hanging plate 11, a connecting frame 14 and a second elastic member 16. The first hanging plate 11 is connected to the right side of the vehicle. The connecting frame 14 is connected to the frame 2. One side of the first hanging plate 11 is provided with a first limiting plate 12. The front end of the first limiting plate 12 is provided with a second limiting plate 15. The rear end of the first limiting plate 12 is provided with a support seat 13. One end of the connecting frame 14 is rotatably connected to the support seat 13. The other relative end of the connecting frame 14 and the second limiting plate 15 are connected by a second elastic member 16. In a specific embodiment, the support seat 13 is rotatably connected with a rotating shaft (not labeled), and the rotating shaft is connected to the connecting frame 14.

[0042] Under normal working conditions, the connecting frame 14 fits against the first limiting plate 12 under the action of the second elastic member 16. During the process of accidentally turning the steering wheel to the left to the correction of the vehicle, the first hanging plate 11, the first limiting plate 12, the second limiting plate 15 and the support seat 13 will rotate counterclockwise around the rotating shaft as a whole. However, under the action of the rotating shaft and the first elastic member 34, the connecting frame 14 will not rotate, and the first weeding component 3, the second weeding component 4 and the third weeding component 5 will still remain in the normal working position and work normally.

[0043] The frame 2 is provided with a second hanging plate 21, and the second hanging plate 21 is in plug-in fit with the connecting frame 14. In a specific embodiment, four first hooks 17 are provided on the side surface of the first hanging plate 11, and the four first hooks 17 are connected to the side surface of the vehicle. Four second hooks 22 are provided on the side surface of the second hanging plate 21, and four insertion holes 141 are provided at one end of the connecting frame 14 away from the support base 13. The four insertion holes 141 are in plug-in fit with the four second hooks 22. When fine operation is required, the second hanging plate 21 and the connecting frame 14 are plugged together. When fine operation is not required, the frame 2 is directly connected to the vehicle, so that the present invention can be applied to different working requirements.

[0044] The number of the second elastic members 16 is two. One second elastic member 16 is located between the top end of the second limiting plate 15 and the top end of the connecting frame 14, and the other second elastic member 16 is located between the bottom end of the second limiting plate 15 and the bottom end of the connecting frame 14. In a specific embodiment, the second elastic member 16 is a damping spring.

[0045] The working principle of the present invention is as follows:

[0046] When fine operation is not required, the connecting component 1 is not used. The four second hooks 22 on the second hanging plate 21 are directly installed on the right side surface of the vehicle. The two guide wheels 38 of the first weeding component 4 are in contact with the top surface, the two guide wheels of the second weeding component 4 are in contact with the first side surface 62, the two guide wheels of the third weeding component 5 are in contact with the ground, and the 6 first elastic members are in a compressed state. The vehicle driver drives the vehicle with reference to the auxiliary line of the emergency lane and observes the weeding situation through the right rearview mirror of the vehicle.

[0047] When fine operation is required, the connecting component 1 is used. The four insertion holes 141 are inserted into the second hooks 22. The four first hooks 17 are installed on the right side surface of the vehicle. The two guide wheels 38 of the first weeding component 4 are in contact with the top surface, the two guide wheels of the second weeding component 4 are in contact with the first side surface 62, the two guide wheels of the third weeding component 5 are in contact with the ground, and the 6 first elastic members are in a compressed state. The vehicle driver drives the vehicle with reference to the auxiliary line of the emergency lane and observes the weeding situation through the right rearview mirror of the vehicle.

[0048] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly.
