Description

Technical Field

[0001] This invention relates to the field of concrete leveling technology, and more specifically to a ground leveling robot with an auger at an angle. Background Technology

[0002] Currently, the smoothing of concrete after paving is generally carried out using large machinery or manually. Larger machinery is limited by the application environment and is mostly used in highway paving. For small-scale concrete paving, especially in indoor environments, large smoothing equipment is unsuitable. Therefore, manual smoothing or disc-type smoothing devices are usually used. However, disc-type smoothing devices have drawbacks: a narrow smoothing range, low work efficiency, and seams at the boundaries of smoothing areas. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention proposes a ground smoothing robot equipped with an auger that can effectively solve the problem of seams at the junction of smoothing sections, and has high working efficiency and a larger smoothing range.

[0004] The technical solution of this invention is implemented as follows:

[0005] A ground leveling robot with an auger includes a vehicle body, an inclined scraper at the front end of the vehicle body, and an auger spiral soil loosening section disposed within the inclined scraper, wherein:

[0006] When the vehicle body is reversing, the auger spiral soil-loosening part rotates counterclockwise, which is used to push the concrete it carries up to the right side of the inclined scraper while loosening the soil.

[0007] A screw lifting device is provided between the inclined scraper and the vehicle body, and the screw lifting device is used to adjust the height of the inclined scraper.

[0008] A side mesh plate and a bottom mesh plate are respectively provided on the right side and the right side of the bottom of the inclined scraper. The inclined scraper, together with the side mesh plate and the bottom mesh plate, forms a storage area for storing the stones pushed to the right side of the inclined scraper by the auger spiral.

[0009] The left, rear and bottom sides of the inclined scraper are open, and an anti-jamming structure is provided at the right end of the auger shaft of the auger shaft to prevent jamming of the auger shaft in the auger shaft loosening part. The anti-jamming structure is located in the storage area.

[0010] Furthermore, the top surface of the inclined scraper is a flat surface, its front side is an inclined surface with the bottom end tilted forward, and the front end face of the bottom mesh plate contacts the inner surface of the front end of the inclined scraper. The bottom mesh plate is configured such that the rear end height is greater than the front end height, and the height of the outer end of the bottom mesh plate is less than the height of its inner end.

[0011] Furthermore, the auger shaft is connected to a first motor mounted on the vehicle body at one end corresponding to the left side of the inclined scraper, and a second motor is provided on the lead screw lifting device.

[0012] Furthermore, the anti-jamming structure includes a first incomplete gear, a second incomplete gear, a scraper, and a tension spring. The first incomplete gear is fixedly installed on the right end of the auger shaft. The second incomplete gear is rotatably disposed inside the inclined scraper. Two scrapers are provided and fixedly disposed at both ends of the second incomplete gear. The tension spring is disposed inside the inclined scraper, and one end of the tension spring is connected to one of the scrapers. When the first incomplete gear rotates with the auger shaft, it causes the scraper to make a circular motion through the second incomplete gear. While stretching the tension spring, the scraper cleans the right end of the auger shaft.

[0013] Furthermore, the top end of the side mesh plate and the inner end of the bottom mesh plate are rotatably engaged with the inclined scraper, and a material removal driving part is provided between the side mesh plate and the bottom mesh plate for simultaneously driving the outer end of the bottom mesh plate to rotate downward and the bottom end of the side mesh plate to rotate outward to an open state.

[0014] Furthermore, the material removal drive part includes a material removal drive gear, a material removal drive rack, and a storage spring, wherein: the material removal drive gear is coaxially fixed to the top of the side mesh plate, the material removal drive rack is vertically mounted on the inclined scraper plate, the material removal drive rack meshes with the material removal drive gear, and the bottom end of the material removal drive rack is connected to the bottom mesh plate, and the storage spring is disposed between the material removal drive rack and the inclined scraper plate to keep the side mesh plate and the bottom mesh plate in a closed state in the initial state.

[0015] Furthermore, a third incomplete gear is coaxially fixed on the disengagement drive gear, the third incomplete gear meshes with a fourth incomplete gear, the fourth incomplete gear is connected to a traveling wheel, the traveling wheel is disposed on the inclined scraper, and the traveling wheel is located within the inclined scraper in the width direction, wherein the traveling wheel is configured to open the side mesh plate and the bottom mesh plate through the fourth incomplete gear and the third incomplete gear when the vehicle body moves forward.

[0016] Furthermore, a reset plate is fixedly provided on the third incomplete gear, and a reset spring is connected to one side of the reset plate. The reset spring is configured to restore the third incomplete gear to its initial state after the third incomplete gear and the fourth incomplete gear disengage.

[0017] Furthermore, the third incomplete gear has an arc-shaped groove, and a limiting rod with one end fixed to the inclined scraper is provided in the arc-shaped groove. When the third incomplete gear is in the initial state and when the third incomplete gear rotates to the state of disengagement from the fourth incomplete gear, the limiting rod contacts the two ends of the arc-shaped groove respectively.

[0018] Furthermore, the inclined scraper is provided with a one-way locking drive structure that is connected between the traveling wheel and the fourth incomplete gear. The one-way locking drive structure is configured to drive the side mesh plate and the bottom mesh plate to open when the vehicle body moves forward, and the one-way locking drive structure is configured to make the traveling wheel roll on the ground and keep the side mesh plate and the bottom mesh plate in a closed state when the vehicle body reverses.

[0019] The present invention has the following beneficial effects:

[0020] 1. The sloping scraper of this invention is designed as a sloping surface rather than a flat surface, which can squeeze the excess concrete to the front right side when smoothing the second route. This way, when turning and smoothing the second route, the excess concrete will not be squeezed into the area that has already been smoothed on the other side.

[0021] 2. The present invention features a device for collecting small stones on the front right side of the inclined scraper, which can solve problems such as impurities in some concrete. Furthermore, the bottom mesh plate is designed with an inclined angle of approximately 5 degrees, which effectively collects the small stones rolled up by the auger's loosening section in the corner on the front right side. The concrete flows out through the mesh, while the small stones remain in the collection device on the front right side.

[0022] 3. In this invention, the soil is loosened by the screw conveyor before being smoothed. This can lift up some small stones in the concrete and break up some hard lumps, resulting in a better smoothing effect.

[0023] 4. The anti-jamming structure of this invention can prevent the auger shaft from jamming and maintain the long-term effective operation of the device. Attached Figure Description

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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.

[0033] Please see Figures 1 to 8 As shown, the ground leveling robot with auger provided in this embodiment of the invention mainly includes a vehicle body 1, an inclined scraper 2, an auger spiral soil loosening part 3, a screw lifting device 4, a side mesh plate 5, and a bottom mesh plate 6.

[0034] The vehicle body 1 is equipped with a control compartment, which can be used to control the vehicle body 1 to move forward, backward or turn, and the control compartment is also used to control the operation of the auger spiral soil loosening part 3 and the screw lifting device 4.

[0035] In this embodiment, the wheel section of the vehicle body 1 is preferably designed as a tracked structure.

[0036] The inclined scraper 2 is located at the front end of the vehicle body 1 and is used to smooth the concrete when the vehicle body 1 is reversing.

[0037] Specifically, the left, right and bottom sides of the inclined scraper 2 are all open.

[0038] The auger spiral soil loosening part 3 is located inside the inclined scraper 2. It is used to contact the concrete before the inclined scraper 2 when the vehicle body 1 is reversing, and achieve the soil loosening effect by rotating counterclockwise. At the same time, during the rotation, it pushes the concrete and excess concrete carried up to the right side of the inclined scraper 2.

[0039] The lead screw lifting device 4 is located between the inclined scraper 2 and the vehicle body 1. As an intermediate component for mounting the inclined scraper 2 onto the vehicle body 1, it is mainly used to adjust the height of the inclined scraper 2.

[0040] Side mesh plate 5 and bottom mesh plate 6 are respectively set on the right side of the inclined scraper 2 and the right side of the bottom of the inclined scraper 2. At this time, the front side and top of the inclined scraper 2 will cooperate with the side mesh plate 5 and bottom mesh plate 6 to form a storage area for storing stones pushed to the right side of the inclined scraper 2 by the auger spiral loosening part 3.

[0041] Specifically, what is actually pushed into the storage area by the auger spiral loosening part 3 is concrete, which contains gravel and concrete slurry. The slurry will flow directly out through the mesh on the side mesh plate 5 and the bottom mesh plate 6 back to the ground, while the gravel will be trapped in the storage area.

[0042] The auger shaft 3.1 is connected to a first motor mounted on the vehicle body 1 at one end corresponding to the left side of the inclined scraper 2, and a second motor is installed on the screw lifting device 4. The anti-jamming structure 7 is located inside the inclined scraper 2 and is set at the right end of the auger spiral soil loosening part 3. It is used to prevent the right end of the auger shaft 3.1 of the auger spiral soil loosening part 3 from being jammed by the concrete pushed to the right by the soil loosening part of the auger bolt, and the anti-jamming structure 7 is located in the storage area.

[0043] More specifically, the top surface of the inclined scraper 2 is a flat surface, its front side is an inclined surface with the bottom end tilted forward, and the front end face of the bottom mesh plate 6 contacts the inner surface of the front end of the inclined scraper 2. The bottom mesh plate 6 is configured such that the rear end height is greater than the front end height, and the height of the outer end of the bottom mesh plate 6 is less than the height of its inner end.

[0044] At this time, the stones in the storage area will be more concentrated at the right front corner of the inclined scraper 2, so that the stones can be piled up from the inside to the outside in the storage area, making it easier for subsequent stones to enter the storage area, while preventing stones from falling back to the ground from the inner opening of the storage area.

[0045] In an embodiment of the present invention, the anti-jamming structure 7 includes a first incomplete gear 7.1, a second incomplete gear 7.2, a scraper 7.3, and a tension spring 7.4. The first incomplete gear 7.1 is fixedly installed on the right end of the auger shaft 3.1. The second incomplete gear 7.2 is rotatably disposed inside the inclined scraper 2. Two scrapers 7.3 are provided and fixedly disposed at both ends of the second incomplete gear 7.2. The tension spring 7.4 is disposed inside the inclined scraper 2, and one end of the tension spring 7.4 is connected to one of the scrapers 7.3. When the first incomplete gear 7.1 rotates with the auger shaft 3.1, it will cause the scraper 7.3 to make a circular motion through the second incomplete gear 7.2. The scraper 7.3 cleans the right end of the auger shaft 3.1 while stretching the tension spring 7.4.

[0046] Specifically, in the initial state, both scrapers 7.3 are located on top of the second incomplete gear 7.2, and the front end of the tension spring 7.4 is connected to the rear scraper 7.3 of the two scrapers 7.3, while the rear end of the tension spring 7.4 is connected to other parts of the inclined scraper 2. At this time, when the scraper 7.3 cleans the concrete or gravel accumulated at the right end of the auger shaft 3.1, the scraper 7.3 rotates clockwise from top to bottom, allowing the cleaned concrete or gravel to effectively enter the storage area.

[0047] When the anti-jamming structure 7 is activated, the first incomplete gear 7.1 rotates counterclockwise following the auger shaft 3.1. The teeth of the first incomplete gear 7.1 push the concrete and gravel storage area accumulated on the bottom mesh plate 6 to one side. At this time, on the one hand, it improves the effect of concrete and gravel near the inner opening of the storage area entering the storage area. At the same time, by pushing the displacement of concrete and gravel at this position, it improves the efficiency of concrete slurry leakage from the bottom mesh plate 6 and the side mesh plate 5. It can also prevent gravel from accumulating between the bottom mesh plate 6 and the side mesh plate 5 near the auger shaft 3.1 to a certain extent, improving the flowability of concrete slurry in this part, and thus better preventing the auger shaft 3.1 from jamming.

[0048] In another embodiment of the present invention, a material removal drive part 8 is also provided, which is mainly used to remove the stones stored between the side mesh plate 5 and the bottom mesh plate 6.

[0049] Specifically, the top of the side screen plate 5 and the inner end of the bottom screen plate 6 are rotatably engaged with the inclined scraper 2. When the unloading drive part 8 is activated, it simultaneously drives the outer end of the bottom screen plate 6 to rotate downward and the bottom end of the side screen plate 5 to rotate outward to open.

[0050] The material removal drive unit 8 includes a material removal drive gear 8.1, a material removal drive rack 8.2, and a storage spring 8.3. The material removal drive gear 8.1 is coaxially fixed to the top of the side screen plate 5. Specifically, an upper rotating shaft is provided on the top of the side screen plate 5, and the side screen plate 5 achieves rotational engagement with the inclined scraper 2 through the upper rotating shaft, and the material removal drive gear 8.1 is fixed on the upper rotating shaft. The inner end of the bottom screen plate 6 achieves rotational engagement with the inclined scraper 2 through a lower rotating shaft.

[0051] The stripping drive rack 8.2 is vertically and flexibly mounted on the inclined scraper 2. The stripping drive rack 8.2 meshes with the stripping drive gear 8.1, and the bottom end of the stripping drive rack 8.2 is connected to the bottom mesh plate 6. A storage spring 8.3 is disposed between the stripping drive rack 8.2 and the inclined scraper 2 to keep the side mesh plate 5 and the bottom mesh plate 6 in a closed state in the initial state. Specifically, in the initial state of this embodiment, the storage spring 8.3 uses its own elastic force to apply an upward elastic force to the stripping drive rack 8.2, so that the stripping drive rack 8.2 is in the highest position, and both the side mesh plate 5 and the bottom mesh plate 6 are in a closed state. When an external force causes the material removal drive gear 8.1 to rotate or the material removal drive rack 8.2 to move downwards, the bottom end of the side mesh plate 5 rotates outwards and the outer end of the bottom mesh plate 6 rotates downwards, switching the side mesh plate 5 and the bottom mesh plate 6 to the open state. At this time, the energy storage spring 8.3 is stretched, and the stones or concrete stored between the side mesh plate 5 and the bottom mesh plate 6 will be released. After the external force disappears, the energy storage spring 8.3 automatically closes the side mesh plate 5 and the bottom mesh plate 6 during the recovery process.

[0052] Furthermore, a third incomplete gear 9 is coaxially fixed to the disengaged drive gear. At this time, the third incomplete gear 9 can be fixed on the upper rotating shaft. The third incomplete gear 9 meshes with a fourth incomplete gear 10, which is connected to a traveling wheel 11. The traveling wheel 11 is located on the inclined scraper 2 and is within the inclined scraper 2 in the width direction. The traveling wheel 11 is configured to open the side mesh plate 5 and the bottom mesh plate 6 through the fourth incomplete gear 10 and the third incomplete gear 9 when the vehicle body 1 moves forward.

[0053] Specifically, since the third incomplete gear 9 and the fourth incomplete gear 10 have meshing and disengaging processes during the rotation of the walking wheel 11, the side screen plate 5 and the bottom screen plate 6 will continuously open and close during the continuous rotation of the walking wheel 11, thereby achieving a continuous shaking process of the side screen plate 5 and the bottom screen plate 6 and improving the material removal effect.

[0054] Among them, a reset plate 12 is fixedly provided on the third incomplete gear 9, and a reset spring 13 is connected to one side of the reset plate 12. The reset spring 13 is configured to restore the third incomplete gear 9 to its initial state after the third incomplete gear 9 and the fourth incomplete gear 10 disengage.

[0055] At this time, the cooperation of the reset plate 12 and the reset spring 13, and the cooperation of the material removal drive part 8, allow the storage spring 8.3 and the reset spring 13 to provide greater elastic force during the closing process of the side mesh plate 5 and the bottom mesh plate 6, making the closing process of the mesh plate and the bottom mesh plate 6 more instantaneous and improving the shaking material removal effect.

[0056] In addition, an arc-shaped groove 14 is provided on the third incomplete gear 9, and a limiting rod 15 with one end fixed to the inclined scraper 2 is provided in the arc-shaped groove 14. When the third incomplete gear 9 is in the initial state and when the third incomplete gear 9 rotates to the state of disengagement from the fourth incomplete gear 10, the limiting rod 15 contacts the two ends of the arc-shaped groove 14 respectively.

[0057] At this time, the limiting rod 15, through its cooperation with the arc groove 14, can not only limit the extreme angle of rotation of the third incomplete gear 9 under the drive of the fourth incomplete gear 10, but also cooperate with the reset spring 13 in the initial state to maintain the position of the teeth of the third incomplete gear 9, so that the third incomplete gear 9 can better cooperate with the fourth incomplete gear 10 and be driven by the fourth incomplete gear 10.

[0058] Furthermore, in an embodiment of the present invention, a one-way locking drive structure 16 is also provided.

[0059] The one-way locking drive structure 16 is driven between the traveling wheel 11 and the fourth incomplete gear 10. It is mainly used to drive the side mesh plate 5 and the bottom mesh plate 6 to open when the vehicle body 1 moves forward by rotating the traveling wheel 11, and to keep the side mesh plate 5 and the bottom mesh plate 6 closed when the vehicle body 1 reverses, while allowing the traveling wheel 11 to roll.

[0060] Specifically, the one-way locking drive structure 16 includes an inner ratchet ring 16.1, a ratchet gear 16.2, a gear set 16.3, and a transmission structure 16.4.

[0061] The gear set 16.3 includes two meshing spur gears, one of which is coaxially fixed to the fourth incomplete gear 10, and the other is fixed to the inner ratchet ring 16.1, which is rotatably mounted on the inclined scraper 2.

[0062] The ratchet 16.2 is coaxially disposed in the inner ratchet ring 16.1. The ratchet 16.2 includes a main body and two ratchet teeth disposed on the main body. The ratchet 16.2 is connected to the traveling wheel 11 through the transmission structure 16.4, and the ratchet teeth of the inner ratchet ring 16.1 are configured to be in a retractable and extendable state.

[0063] In this embodiment, when the vehicle body 1 moves forward, the traveling wheels 11 drive the ratchet 16.2 to rotate forward through the transmission structure 16.4. The ratchet 16.2 drives the inner ratchet ring 16.1 to rotate forward. At this time, the gear set 16.3 rotates and drives the fourth incomplete gear 10 to move. Therefore, the side mesh plate 5 and the bottom mesh plate 6 will eventually open when the vehicle body 1 moves forward. As the vehicle body 1 continues to move forward, the side mesh plate 5 and the bottom mesh plate 6 will continuously vibrate by switching between open and closed states.

[0064] When the vehicle body 1 reverses, the traveling wheels 11 drive the ratchet 16.2 to rotate in the opposite direction via the transmission structure 16.4. At this time, due to the elastic action of the return spring 13 and the storage spring 8.3, the side mesh plate 5 and the bottom mesh plate 6 have a force to keep them closed. Furthermore, the ratchet teeth of the inner ratchet 16.2 are designed to be in a spring-loaded and retractable state, so that when the ratchet 16.2 rotates in the opposite direction, its ratchet teeth will continuously compress the ratchet teeth on the inner ratchet ring 16.1 that it passes through into the inner ratchet ring 16.1, and will not drive the inner ratchet ring 16.1 to rotate in the opposite direction.

[0065] 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, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
