DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figures 1 to 6 As shown, a raw material transportation device for concrete processing includes a base 1, four rollers 23 are movably installed at the bottom of the base 1, a horizontal plate 3 is slidably installed in the inner cavity of the base 1, two third grooves 302 are provided on one side of the horizontal plate 3, and two second limit plates 44 and second support plates 5 are fixedly installed on the top of the horizontal plate 3; it also includes a storage mechanism for storing concrete processing raw materials; the storage mechanism includes two first support plates 4, the two first support plates 4 are respectively slidably installed on the inner surface of the third groove 302, a limit ring 41 is fixedly installed on the top of the first support plate 4, and the second limit ring 41 is fixedly installed on the top of the first support plate 4. A rack 42 is fixedly mounted on one side of a support plate 4, and a gear 45 is meshed with the rack 42. The gear 45 is rotatably mounted on one side of a second limiting plate 44. A pulley 46 is fixedly connected to one side of the gear 45. The two pulleys 46 are driven by a belt 47. A first motor 48 is fixedly connected to one side of the belt 47. The first motor 48 is fixedly mounted on the top of the horizontal plate 3. A raw material box 52 is rotatably mounted on the opposite surfaces of the two second support plates 5. Two limiting columns 521 are fixedly mounted on one side of the raw material box 52. The limiting columns 521 are slidably mounted in the inner cavity of the limiting ring 41. Two first limiting plates 43 are fixedly mounted on the top of the transverse plate 3 , and the first supporting plate 4 is slidably mounted on the inner surface of the first limiting plates 43 . The two gears 45 are not in the same horizontal plane.

[0022] During the transportation of concrete raw materials, we must not only consider the shock absorption of the concrete raw materials but also the unloading of the concrete raw materials after transporting them to the designated location. In addition, since the transportation of concrete raw materials is generally carried out outdoors and the natural wind in the external environment is strong, the concrete pigments need to be covered to prevent strong winds from blowing away the concrete raw materials and causing pollution to the environment.

[0023] When the present invention is in use, firstly, the concrete raw material is placed in the raw material box 52, and then the staff can push the transport device to transport the concrete raw material. After the concrete raw material is transported to the designated location, the output shaft of the first motor 48 drives the pulley 46 to rotate, and the two pulleys 46 start to rotate through the belt 47, and the two pulleys 46 drive the two gears 45 to rotate at the same time. The two gears 45 are respectively meshed with the two racks 42. Since the meshing positions of the two gears 45 and the two racks 42 are different, the two gears 45 can respectively drive the two racks 42 to move in the upward and downward directions when in use. When the two racks 42 move up and down, they will drive the two first support plates 4, and then the two first support plates 4 will also move to the left and right respectively. When the two first support plates 4 move up and down, the first limiting plate 43 can limit and protect the first support plate 4, and can prevent the first support plate 4 from deviating from the predetermined moving path. When the two first support plates 4 move, they will slide up and down with the limiting rings 41. As the two limiting rings 41 move up and down respectively, the two limiting posts 521 also slide on the inner surfaces of the two limiting rings 41 respectively. When the two limiting posts 521 are not at the same height, the raw material box is in a tilted state, and then due to the tilt of the raw material box 52, the concrete raw materials in the inner cavity of the raw material box 52 will be completely discharged. In this process, the raw material box 52 rotates with the rotating shaft 51 as the center of rotation under the action of the rotating shaft 51. Therefore, during the process of unloading the raw materials, the entire concrete raw material transportation device can still maintain balance.

[0024] Further, such as Figure 2 As shown, four connecting plates 2 are fixedly installed at the bottom of the base 1, four first dampers 21 are fixedly installed at the bottom of the connecting plate 2, and a mounting plate 22 is fixedly connected to the bottoms of two adjacent first dampers 21, and the roller 23 is rotatably installed between two adjacent mounting plates 22.

[0025] When the present invention is in use, since the concrete transport device is generally used on construction sites, and the road surface on the construction sites is generally uneven, the concrete transport device may encounter pits or bumps during driving, and the pits and bumps not only easily cause the concrete transport device to be unable to move, but also easily cause the concrete in the concrete transport device to spill. Therefore, the concrete transport device needs to be kept stable during the concrete transportation process. Therefore, when in use, the first damper 21 is contracted or extended, and there are four first dampers 21 on the top of a single roller 23. A total of sixteen first dampers 21 work together on the four rollers 23. When a single roller 21 encounters a pit or a bump, the four first dampers 23 on the top of the roller 21 cooperate to keep the base 1 balanced. The concrete transport device is pushed by the staff, and the roller 23 rotates to achieve the purpose of transporting concrete raw materials.

[0026] Further, such as Figure 3 As shown, the top of the base 1 is provided with two first grooves 11, the inner surface of the first groove 11 is fixedly provided with a second groove 301, one end of the second groove 301 is fixedly connected with a second damper 31, the second damper 31 is slidably provided on the inner surface of the first groove 11, a connecting rod 32 is rotatably provided on the top of the second damper 31, and the connecting rod 32 is rotatably provided on the bottom of the horizontal plate 3; Four mounting tubes 33 are fixedly installed on the top of the base 1, and a third damper 34 is fixedly installed on the inner surface of the mounting tube 33. A sliding plate 35 is fixedly connected to the top of the third damper 34. The sliding plate 35 is slidably installed on the inner surface of the mounting tube 33. A connecting column 36 is fixedly connected to the top of the sliding plate 35, and the connecting column 36 is fixedly installed on the bottom of the cross plate 3.

[0027] When the present invention is in use, the gravity of all concrete raw materials is pressed on the cross plate 3. When in use, in order to reduce the shaking and vibration caused by the uneven road surface, when the cross plate 3 fluctuates up and down, the connecting rod 32 will squeeze the second damper 31, and the second damper 31 slides on the inner surface of the first groove 11. Then the second damper 31 is squeezed, and the second damper 31 shrinks in the second groove 301 and absorbs the pressure from the connecting rod 32. The second damper 31 shrinks and can also reduce the amplitude of the up and down sliding of the cross plate 3, thereby reducing the shaking amplitude of the cross plate 3 and achieving the purpose of shock absorption. When the cross plate 3 slides downward, a part of the gravity on the cross plate 3 will suppress the connecting column 36, and then be transmitted to the sliding plate 35 through the connecting column 36. The sliding plate 35 slides on the inner surface of the mounting tube 33. At this time, the third damper 34 contracts to absorb part of the energy, thereby reducing the shaking amplitude of the cross plate 3 and the raw material box 52 on the top of the cross plate 3, and further reducing the shaking amplitude of the cross plate 3, thereby achieving the purpose of shock absorbing the cross plate 3.

[0028] Further, such as Figure 6 As shown, the two second support plates 5 have rotating shafts 51 fixedly mounted on opposite surfaces, a rotating hole is opened on one side of the raw material box 52, and the rotating shaft 51 is rotatably mounted on the inner surface of the rotating hole.

[0029] The top of the raw material box 52 is provided with two fourth grooves 53, the inner surface of the fourth groove 53 is rotatably mounted with a threaded rod 54, the inner surfaces of the two fourth grooves 53 are slidably mounted with a blocking rod 55, and the two threaded rods 54 are threadedly connected with the blocking rod 55; A sealing cloth 56 is slidably mounted on the outer surface of the threaded rod 54 . One end of the threaded rod 54 passes through the raw material box 52 and is fixedly connected to a second motor 57 . The second motor 57 is fixedly mounted on one side of the raw material box 52 .

[0030] When the present invention is in use, during the transportation of concrete raw materials, in order to reduce the pollution caused by the outward diffusion of the concrete raw materials, the output shaft of the second motor 57 drives the two threaded rods 54 to rotate at the same time. The two second motors 57 are of the same model and rotate synchronously. The rotation of the threaded rod 54 can drive the blocking rod 55 to slide on the inner surface of the fourth groove 53. When the blocking rod 55 slides, it can stretch the sealing cloth 56 to cover the entire top of the raw material box 52 to avoid dust. The internal space of the fourth groove 53 can store the rolled-up sealing cloth 56. When the concrete raw materials in the raw material box 52 need to be released, the output shaft of the second motor 57 drives the threaded rod 54 to rotate to drive the blocking rod 55 to compress and roll up the sealing cloth 56, thereby facilitating the staff to unload the concrete raw materials.

[0031] Working principle: first, the concrete raw material is placed in the inner cavity 523, and then the two second motors 57 output shafts are used to synchronously drive the two threaded rods 54 to rotate. The two threaded rods 54 can make the blocking rod 55 slide on the inner surface of the fourth groove 53, and then the blocking rod 55 with the sealing cloth 56 stretches and covers the entire top of the raw material box 52. This can prevent the concrete raw material from being blown into the air during the transportation of the concrete raw material, causing pollution. When the concrete raw material needs to be unloaded, the two second motors 57 are used to rotate synchronously to drive the two threaded rods 54 to rotate, and the two threaded rods 541 then drive the blocking rod 55 with the sealing cloth 56 to move, exposing the concrete raw material. In the air, to prevent the sealing cloth 56 from affecting the unloading of concrete raw materials, the output shaft of the first motor 48 drives the pulley 46 to rotate, and through the transmission of the belt 47, the two pulleys 46 respectively drive the two gears 45 to rotate. Since the two gears 45 have different meshing positions with the two racks 42, when the two gears 45 rotate at the same time, they can drive the two racks 42 to move up and down respectively. In this process, the two limit columns 521 slide in the inner cavities of the two limit rings 41 respectively, and the raw material box 52 rotates with the rotating shaft 51 as the center of the circle, so that the raw material box 52 reaches a tilted state, which is convenient for the staff to unload all the concrete raw materials in the raw material box 52.

[0032] During the transportation process, the cooperation between the first damper 21 and the mounting plate 22 can enable the transport device to maintain balance when encountering pits or bumps, thereby preventing the transport device from tilting when encountering special circumstances. At the same time, when the top of the cross plate 3 is squeezed, the connecting rod 32 rotates on the inner surface of the second damper 31, and the second damper 31 shrinks in the second groove 301 to absorb and slowly release the squeezing force. This can reduce the cross plate 3 from moving a large distance in a short time when it is pressed downward, thereby reducing the swing amplitude of the cross plate 3 and the raw material box 52, thereby achieving the purpose of reducing the swing amplitude of the raw material box 52. At the same time, the connecting column 36 squeezes the sliding plate 35, and the sliding plate 35 slides in the inner cavity of the mounting tube 33. When the sliding plate 35 slides, the third damper 34 shrinks and slowly releases the downward pressure, which can further reduce the shaking effect on the concrete raw materials.
