Description

Technical Field

[0001] The utility model relates to the technical field of archaeological excavation, and more specifically, to a ground cleaning device. Background Art

[0002] During archaeological excavation, after the scope of archaeological work is determined through aerial photography, electromagnetic surveying instruments and ground-penetrating radar, the surface soil will be cleaned as a whole, and then marking work will be carried out before excavation. Specifically, the location of the underground wall is divided according to the scope of work and the structure in the tomb, forming an excavation grid system. The underground wall and the soil around it will not be dug away. The soil in the grid needs to be cleaned twice, and after the secondary cleaning, archaeological experts will carry out detailed excavation of cultural relics.

[0003] When the soil in the grid system is cleaned for the second time, since each grid corresponds to a different layout of the tomb, it is necessary to measure the soil quality in each grid and determine the depth of each grid to be excavated based on the soil quality. Then, the soil in different grid positions is cleaned manually, and after the second cleaning, multiple rectangular or square foundation pits spaced apart from each other are formed on the surface.

[0004] Since manual secondary cleaning is inefficient and affected by the on-site environment, it is inconvenient to use large equipment for soil excavation. Therefore, it is necessary to design a ground cleaning device that is efficient and easy to use. Utility Model Content

[0046] The utility model proposes a ground cleaning device, which controls the height of a support member through a lifting mechanism, and based on the cooperation of a cutting mechanism and a conveying mechanism on the support member, cuts the soil in a foundation pit and conveys the soil to a collection box at the same time. The cleaning depth is controllable, the device is easy to use, and the cultural relics in the pit will not be crushed.

[0047] A floor cleaning device of the present application is described in detail through the following embodiments.

[0048] In this embodiment, if Figures 1 to 3 As shown, the floor cleaning device comprises: a frame 1;

[0049] The driving mechanism 2 is disposed on the frame 1 and is used to drive the frame 1 to move;

[0050] The lifting mechanism 3 is arranged on the frame 1 and is used to drive the support member 4 to move up and down;

[0051] The support member 4 is provided with a cutting mechanism 5, which is arranged on the bottom surface of the support member 4 and is used for cutting the ground;

[0052] A collection box 6 is arranged on one side of the support member 4;

[0053] The conveying mechanism 7 is obliquely arranged on the supporting member 4 and is used for conveying the soil cut by the cutting mechanism 5 to the collecting box 6 .

[0054] In the present technical solution, the frame 1 is horizontally arranged, and its width matches the width of the foundation pit. The driving mechanism 2 includes a stepper motor, a driving shaft connected to the stepper motor, and a driven shaft symmetrically arranged on the right side of the frame 1. Two rollers are provided on the driving shaft and the driven shaft. By controlling the forward and reverse rotation of the stepper motor, the frame 1 can be controlled to move left and right. The lifting mechanism 3 is vertically fixed in the frame 1. The lifting mechanism 3 includes a driving motor, a screw rod and a guide rod. The driving motor is connected to the screw rod and can drive the screw rod to rotate forward and reverse. The support member 4 is a Z-shaped fixed plate, which is slidably connected to the screw rod of the lifting mechanism 3, and can move up and down with the forward and reverse rotation of the screw rod. The support member 4 is provided with a through hole adapted to the guide rod to guide the up and down sliding of the support member 4.

[0055] The cutting mechanism 5 is fixed on the bottom surface of the support member 4, and the conveying mechanism 7 is tiltedly arranged on the support member 4. When in use, the device is placed on the upper side of the corresponding underground wall, and then the device is driven to move to the desired excavation position through the control of the driving mechanism 2, and the lifting mechanism 3, the cutting mechanism 5 and the conveying mechanism 7 are controlled to start synchronously to excavate the soil at the current position. When the lifting mechanism 3 controls the support member 4 to descend to a certain depth, the lifting mechanism 3 drives the support member 4 to reset upward, and then the driving mechanism 2 is turned on to move one station to the right, and the above actions are repeated until the overall excavation of the current foundation pit is completed.

[0056] In some technical solutions, when working in different foundation pits, the working depth of the lifting mechanism 3 needs to be adjusted accordingly.

[0057] In this embodiment, the cutting mechanism 5 includes:

[0058] The first driving motor 501 is fixedly mounted on the supporting member 4;

[0059] A plurality of rotating wheels 502 are rotatably disposed on the support member 4, and one rotating wheel 502 is connected to the first driving motor 501;

[0060] The saw blade 503 is wound around each rotating wheel 502 , and the first driving motor 501 is used to drive the saw blade 503 to rotate through the rotating wheel 502 .

[0061] In the present technical solution, four rotating wheels 502 are provided, and the four rotating wheels 502 are rectangularly fixed on the bottom surface of the support member 4, and the saw blade 503 is annularly arranged around the circumference of the four rotating wheels 502. The first drive motor 501 is fixed on the upper side of the support member 4, and the output shaft of the first drive motor 501 is connected to a rotating wheel 502. The saw blade 503 can be driven by the first drive motor 501 to rotate on the four rotating wheels 502 to cut the soil on the lower side of the support member 4.

[0062] In some technical solutions, two guide tensioning wheels are provided on the bottom side of the support member 4, and the two guide tensioning wheels abut against the inner and outer sides of the same position of the saw blade 503. On the one hand, they play a tensioning role, and on the other hand, they can play an auxiliary fixing role for the saw blade 503.

[0063] In this embodiment, the cutting mechanism 5 further includes:

[0064] The scraper 504 is fixedly mounted on the support member 4 and is correspondingly mounted on one side of the saw blade 503 .

[0065] In this technical solution, the scraper 504 is a sheet-like member fixed on the support member 4, which can scrape away the soil adhering to the inner wall of the saw blade 503 to prevent the soil from being rolled between the rotating wheel 502 and the saw blade 503. Specifically, four scrapers 504 are provided, and are arranged near the rotating wheel 502.

[0066] In this embodiment, the conveying mechanism 7 includes:

[0067] The second driving motor 701 is fixedly mounted on the support member 4;

[0068] The first belt assembly 702 and the second belt assembly 703 are parallel to each other and rotatably arranged on the support member 4, and the second driving motor 701 is connected to the first belt assembly 702 or the second belt assembly 703;

[0069] The first belt assembly 702 and the second belt assembly 703 are both provided with a plurality of conveying teeth 704 , and the conveying teeth 704 on the sides of the first belt assembly 702 and the second belt assembly 703 that are close to each other are overlapped.

[0070] In the present technical solution, the first belt assembly 702 and the second belt assembly 703 both include: two support shafts and belts, the two support shafts are arranged on the support member 4, one high and one low, staggered left and right, and rotatably, the belts are wound around the two support shafts, and a plurality of conveying teeth 704 are evenly arranged on the belts, and each conveying tooth 704 is arranged horizontally front and back. The first belt assembly 702 is located on the left side, and the second belt assembly 703 is located on the right side. The first belt assembly 702 and the second belt assembly 703 are arranged parallel to each other. The output shaft of the second drive motor 701 and the support shaft of the first belt assembly 702 are two pieces. When the second drive motor 701 is turned on, the first belt assembly 702 is driven to rotate counterclockwise, and the conveying teeth 704 of the first belt assembly 702 act on the conveying teeth 704 of the second belt assembly 703, driving the second belt assembly 703 to rotate clockwise.

[0071] Arranging the conveying mechanism 7 in this way can, on the one hand, avoid interference between the conveying teeth 704 of the first belt assembly 702 and the second belt assembly 703, thereby avoiding the phenomenon of tooth jamming; on the other hand, the conveying teeth 704 of the first belt assembly 702 and the second belt assembly 703 can form a biting or clamping state, effectively causing the soil of the support member 4 to be pulled upward.

[0072] In this embodiment, it also includes:

[0073] The transfer mechanism 8 has one end located at the lower side of the conveying mechanism 7 and the other end extending to the upper side of the collecting box 6 .

[0074] In the present technical solution, the structure of the transfer mechanism 8 is the same as the structure of the combination of the first belt assembly 702 and the second drive motor 701, and is fixed to the right side of the conveying mechanism 7, the left end of the transfer mechanism 8 is located at the lower right side of the conveying mechanism 7, and the right end of the transfer mechanism 8 is located at the upper side of the collection box 6. When in use, the soil on the second belt assembly 703 falls on the transfer mechanism 8, and then the soil is transported to the collection box 6 as the transfer mechanism 8 rotates. Since the conveying mechanism 7 moves up and down with the support member 4 when in use, the transfer mechanism 8 is set to transport the soil for the second time, which is convenient for increasing the height at which the collection box 6 can be set, and increasing the collection and storage capacity.

[0075] In this embodiment, the cutting mechanism 5 is arranged in a ring shape, and the bottom end of the conveying mechanism 7 is located inside the cutting mechanism 5 .

[0076] In the present technical solution, the saw blade 503 of the cutting mechanism 5 is arranged in a ring shape, and the bottom ends of the first belt assembly 702 and the second belt assembly 703 of the conveying mechanism 7 are located in the ring space formed by the saw blade 503. This arrangement improves the mutual coordination between the cutting mechanism 5 and the conveying mechanism 7, and improves the ability of soil excavation and transportation.

[0077] In some technical solutions, the bottom end of the first belt assembly 702 is lower than the bottom end of the saw blade 503, so that the conveying mechanism 7 contacts the soil before the cutting mechanism 5, and the soil is first crushed and conveyed by the conveying teeth 704 on the first belt assembly 702 and the second belt assembly 703, so that the soil cut by the saw blade 503 can fall or dump into the space inside the ring, thereby preventing the saw blade 503 from getting stuck in the soil.

[0078] In some other technical solutions, since all the soil within the circular range of the saw blade 503 must be cut during the first cutting and transportation of the foundation pit, the downward transportation speed of the lifting mechanism 3 can be reduced during the first cutting; when the next position is cut subsequently, the soil can be cut only by the right part of the saw blade 503, and the left part of the saw blade 503 is suspended, that is, the distance between the next position and the previous position is less than the length of the saw blade 503 in the left and right directions.

[0079] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
