DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Combine the following Figure 1-6The present invention is described in detail. A foundation excavation equipment for construction includes: a vehicle body 1, an excavation mechanism and a conveying mechanism. The front end of the vehicle body 1 is provided with an operating platform for controlling the operation of the entire equipment. The excavation mechanism includes two sets of circulation components, multiple bucket bodies 2 and an adjustment component. The circulation component includes a support plate 3, two pulleys 4, a crawler 5, two rotating shafts 6 and a motor 7. The two rotating shafts 6 are both horizontally rotatably installed in the support plate 3 and are symmetrically arranged. The two pulleys 4 are respectively fixedly sleeved on the two rotating shafts 6. The motor 7 is fixedly installed on the inner side of the support plate 3, and the output end is fixedly connected to the end of the rotating shaft 6 on the upper side. The crawler 5 is rollingly embedded outside the two pulleys 4. Multiple bucket bodies 2 are telescopic structures, which are composed of two first sleeves 201 and second sleeves 202 that are slidably sleeved. The bucket bottoms at the ends of the first sleeve 201 and the second sleeve 202 that are away from each other are respectively fixedly connected to the outer sides of the two crawlers 5. The motor 7 runs to drive the rotating shaft 6 to rotate, the rotating shaft 6 drives the pulley 4 to rotate, the pulley 4 drives the crawler 5 to rotate, and the two crawlers 5 drive the multiple bucket bodies 2 located thereon to rotate, so as to realize the circular movement of the bucket bodies 2 and perform excavation operations on the soil layer. The sides of the two support plates 3 that are close to each other are connected by two first telescopic cylinders 8, and the two ends of the first telescopic cylinders 8 are respectively fixedly connected to the inner walls of the two support plates 3, and the two support plates 3 are connected to the vehicle body 1 through the adjustment components.

[0035] The adjustment assembly includes a support rod 9, two sliders 10, two brackets 11, a servo motor 12 and two groups of sliding parts. The two brackets 11 are respectively fixedly mounted on the upper parts of both sides of the vehicle body 1. The support rod 9 is rotatably sleeved in the two brackets 11. The servo motor 12 is fixedly mounted on the upper side of the vehicle body 1, and the output end is fixedly connected to the end of the support rod 9 for torque transmission. A sliding opening 13 is opened in the middle of the two support plates 3. The slider 10 is slidably embedded in the sliding opening 13 and slidably sleeved on the support rod 9. The two groups of sliding parts are respectively arranged in the two sliding openings 13.

[0036] The sliding component includes a driving motor 14 , a gear 15 and a rack 16 . The rack 16 is fixedly mounted on the inner wall of the sliding opening 13 . The driving motor 14 is fixedly mounted in the slider 10 . The gear 15 is fixedly sleeved on the output shaft of the driving motor 14 and meshed with the rack 16 .

[0037] When using this equipment to excavate the foundation, the vehicle body 1 is moved to the area to be excavated through the operating platform, and then the two first telescopic cylinders 8 are started. The first telescopic cylinders 8 are extended and retracted to move the two support plates 3 closer to or farther from each other, thereby driving the two groups of circulation components closer to or farther from each other, so that the first sleeve 201 and the second sleeve 202 are extended or shortened, thereby changing the length of the bucket body 2 to meet the excavation needs of tunnels of different widths.

[0038] As the vehicle body 1 moves, the direction of the excavated tunnel is controlled, and at the same time, the servo motor 12 and the drive motor 14 operate to drive the support rod 9 to deflect, the support rod 9 drives the slider 10 to deflect, and the slider 10 drives the support plate 3 to deflect, thereby realizing the angular deflection of the circulation component, and the drive motor 14 rotates, and the gear 15 and the rack 16 are engaged to move the support plate 3, thereby realizing the change of the inclination angle of the excavating mechanism and the length distance between the excavation mechanism and the ground to meet the needs of tunnel excavation operations at different depths.

[0039] The conveying mechanism includes a first power roller mechanism 17, a second power roller mechanism 18 and a slide 19. The first power roller mechanism 17 is horizontally arranged on the upper side of the vehicle body 1, and the conveying direction is backward. The second power roller mechanism 18 is fixedly installed at the rear of the vehicle body 1, and the conveying direction is to the outside of the vehicle body 1. The slide 19 is arranged on the bottom side of the first power roller mechanism 17. The first power roller mechanism 17, the slide 19 and the vehicle body 1 are connected by four sets of linkage mechanisms. The output end of the second power roller mechanism 18 is longer than the output end of the slide 19, and the output ends of the two point to the same side.

[0040] The linkage mechanism includes a sleeve 20, a support rod 21, four tension springs 22 and a connecting frame 23. The support rod 21 is vertically fixedly installed at the bottom of the first power roller mechanism 17. The sleeve 20 is fixedly installed on the upper side of the vehicle body 1. The bottom of the support rod 21 is located in the sleeve 20. The four tension springs 22 are horizontally arranged in the sleeve 20 and are evenly distributed in a ring shape. The two ends of the tension spring 22 are respectively fixedly connected to the inner wall of the sleeve 20 and the side wall of the support rod 21. A through hole 211 is opened on the side of the sleeve 20 close to the slide 19. The connecting frame 23 passes through the through hole 211 and the two ends are respectively fixedly connected to the bottom end of the support rod 21 and the side of the slide 19.

[0041] The soil layer excavated by the excavation mechanism is eventually thrown out from the top bucket 2 and falls on the first power roller mechanism 17. After passing through the first power roller mechanism 17, the soil layer falls on the slide 19 and is finally discharged to one side of the tunnel. The stones mixed in the soil layer are eventually intercepted by the first power roller mechanism 17 and then transported to the second power roller mechanism 18, output by the second power roller mechanism 18, discharged to one side of the tunnel and located on the outside of the soil layer, thereby realizing the separation of the soil layer and the stones, and the soil layer is located on the inside, which is convenient for later landfill.

[0042] After the soil layer is thrown onto the first power roller mechanism 17, it will impact the first power roller mechanism 17, causing the first power roller mechanism 17 to vibrate under the support of the tension spring 22, thereby vibrating and screening the soil layer. At the same time, the slide 19 shakes synchronously to facilitate the discharge of the soil layer.

[0043] Two groups of shock components are provided on the bottom side of the vehicle body 1 . The two groups of shock components are symmetrically arranged and are both connected to the support rod 9 .

[0044] The shock component includes a sleeve 24, an arm 25, a spring 26, a pressure plate 27, a pin 28 and a plurality of vibration motors 29. The sleeve 24 is slidably mounted on the support rod 9, and the end portion is fixedly connected to the outer side of the slider 10. The spring 26 is mounted on the support rod 9, and the two ends are fixedly connected to the side where the sleeve 24 and the bracket 11 are close to each other. The pressure plate 27 is vertically arranged on the bottom side of the vehicle body 1, and the pin 28 is fixedly installed on the inner side of the pressure plate 27. A sliding hole 30 is opened on the rear side of the arm 25, and the arm 25 is slidably mounted on the pin 28 through the sliding hole 30. The front end of the arm 25 is rotatably mounted on the sleeve 24, and a plurality of vibration motors 29 are all fixedly installed in the pressure plate 27.

[0045] Two springs 26 keep the digging mechanism in a centered state.

[0046] Two telescopic rods 31 are horizontally arranged between the two pressure plates 27, and the two ends of the two telescopic rods 31 are fixedly connected to the sides of the two pressure plates 27 that are close to each other. Second telescopic cylinders 32 are vertically fixedly installed in the middle of the upper sides of the two telescopic rods 31, and the top ends of the two second telescopic cylinders 32 are fixedly connected to the bottom side of the vehicle body 1, and the telescopic rods 31 can be freely extended.

[0047] When the earth-moving operation is in progress, the two second telescopic cylinders 32 extend, so that the telescopic rod 31 drives the two pressure plates 27 to move down to the inside of the tunnel. Since the pressure plates 27 are connected to the slider 10 through the pin rod 28, the arm rod 25 and the sleeve 24, they move left and right with the slider 10. While adjusting the width of the earth-moving mechanism, the distance between the two pressure plates 27 can be automatically adjusted so that the outer side of the pressure plate 27 fits against the inner wall of the tunnel. Multiple vibration motors 29 work to vibrate the pressure plates 27, compact the inner wall of the tunnel, avoid scattering of debris, and ensure the quality of the excavation operation.

[0048] The above is only a specific implementation of the invention, but the protection scope of the invention is not limited to it. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the invention. Therefore, the protection scope of the invention should be based on the protection scope defined in the claims.
