According to the utility model discloses a stone material conveyer, not only simple structure but also be convenient for transport stone material 400. Specifically, in a construction site, some large building materials, such as the stone 400, the wood, the cement board, etc., often need to be transported, and usually, a constructor may transport the building materials by using a human power or a small cart, but the constructor may only transport the relatively light stone 400 by using the human power, and may be difficult to transport the building materials by using the human power if the building materials are ultra-thick, ultra-heavy, ultra-large, and hard to transport the building materials by using the small cart, and since the size and the weight of the building materials 400 are relatively large, it is difficult to stably fix the building materials 400 on the cart by using the small cart, the moving of the building materials 400 is easily caused to shake, and the building materials 400 are easily slid from the small cart, thereby causing a safety hazard in the construction site. In the present embodiment, the stone transport device is provided with the main rod 101 extending along the transport direction, and the first support assembly 110 and the second support assembly 120 supporting the main rod 101, the first support assembly 110 supports the main rod 101 along the second direction L2 parallel to the vertical direction, and the roller 202 is rollably installed at the second support assembly 120, so that the stone transport device can easily carry the stone 400 through the roller, which saves manpower and improves work efficiency. The clamping part 300 includes a sub-rod 301 and a clamping member 302 for clamping the stone 400, clamping the stone 400 so that the stone transporter can smoothly move the stone 400.

When the stone material handling device is used, two clamping pieces 302 need to be respectively sleeved at the vertex angles of two ends of a clamped stone material 400, a constructor presses the other end of the main rod 101 downwards, the clamping part 300 is propped up, at the moment, the two clamping pieces 302 clamp the stone material 400, the two ends of the stone material 400 are stressed by the force which points to the middle part of the stone material 400 along the clamping pieces 302 in the oblique direction, the whole stone material 400 is stressed by upward resultant force, the stone material 400 is propped up, the stone material 400 is in a suspended state at the moment, only the roller assemblies 200 of the stone material conveying device are contacted with the ground, the constructor holds the other end of the main rod 101, the stone material conveying device is pushed forwards, the stone material 400 is conveyed, the lever principle is utilized, the labor intensity of the constructor is greatly reduced, time and labor are saved, and the working efficiency is improved. In addition, because the clamping pieces 302 clamp the stone 400, the stone 400 is subjected to upward resultant force, the stone 400 is stably fixed, the safety of constructors is guaranteed, and the potential safety hazard of a construction site caused by the fact that the constructors are hit due to the fact that the stone 400 slides down in the carrying process is avoided.

In some embodiments, in order to support the main rod 101 more stably, the first support assembly 110 includes a first support rod 102 and a second support rod 103, the first support rod 102 and the second support rod 103 are symmetrically disposed on both sides of the main rod 101 along the third direction L3, one end of the first support rod 102 and one end of the second support rod 103 are respectively connected to the main rod 101, and an included angle between one end of the first support rod 102 and one end of the second support rod 103 is an acute angle. Particularly, inferior pole 301 is installed in the one end of mobile jib 101, it is perpendicular with mobile jib 101 along mobile jib 101 extending direction, in order to make constructor when promoting the stone material conveyer forward, can guarantee that stone material 400 and stone material conveyer are stable forward motion together, the thickness direction of the stone material 400 of being lifted needs to keep parallel with mobile jib 101 and stone material conveyer, avoid because stone material 400 atress uneven results in the stone material 400 of being lifted to produce at the removal in-process and rock, and then lead to stone material 400 landing or stone material conveyer to topple over to the skew of one side, endanger constructor's personal safety.

In some embodiments, the first support assembly 110 further includes a first reinforcing bar 104 and a second reinforcing bar 105, the first reinforcing bar 104 and the second reinforcing bar 105 are disposed on one side of the first support bar 102 and the second support bar 103 along the transportation direction, one end of the first reinforcing bar 104 abuts against one end of the second reinforcing bar 105 and is fixed to the main bar 101, and the other end of the first reinforcing bar 104 and the other end of the second reinforcing bar 105 abut against and are fixed to the second support assembly 120, respectively. Specifically, the first support assembly 110 is composed of the first support bar 102 and the second support bar 103, and constitutes a simple support structure for supporting the main bar 101, but in order to make the whole stone material transporting device more stable, the first support assembly 110 further includes a first reinforcing bar 104 and a second reinforcing bar 105, and the first reinforcing bar 104 and the second reinforcing bar 105 are disposed on one side of the first support bar 102 and the second support bar 103 in the transporting direction and are disposed on one side of the first support bar 102 and the second support bar 103 near the clamping portion 300 as front side reinforcing bars.
