[0025] The above scheme is adopted: the main body of the device can be pushed to move through the four sets of universal wheels arranged under the base 1 to transport the building materials. The building materials can be placed in the hopper 3. The two sides of the hopper 3 are reversible baffles. When unloading, the baffles can be flipped downwards and the hopper 3 can be opened for unloading. A handle is arranged on the outer wall of the rear end of the base 1. Pushing the handle can drive the device to move. The supporting mechanism 2 can be flipped toward the front end and fixed, and can play a supporting role when pushing the device downhill, so as to avoid the center of gravity moving forward when going downhill and causing the transfer vehicle to tip over. When not affected by external forces, the block 206 remains in an upward pop-up state due to the elastic force of the spring A205, and is always engaged with a set of grooves 212, which is opposite to the rotation The shaft 202 is limited by the sleeve rod 203; a shifting block is provided on the outer wall of one side of the clamping block 206, and the shifting block passes through the outer wall of one side of the fixed block 204. By shifting the shifting block, the clamping block 206 can be driven to move downward, and the limit of the rotating shaft 202 and the sleeve rod 203 is released, and the sleeve rod 203 can be flipped forward, and the clamping block 206 is engaged with another group of grooves 212 to fix the flipped sleeve rod 203; by pressing the limit block 211, the spring B210 is forced to shrink, and the limit block 211 is out of contact with the clamping groove 207, so that the limit of the moving rod 208 can be released, and the moving rod 208 can be pulled outward, so that the rotating wheel 209 can contact the ground when going downhill, and is supported by the moving rod 208 and the sleeve rod 203.

[0026] like Figures 2 to 4 As shown, the connecting block 201 is fixedly connected to the front end outer wall of the hopper 3, one end of the rotating shaft 202 passes through the outer wall of the connecting block 201, one end of the spring A205 is fixedly connected to the outer wall of the clamping block 206, the other end of the spring A205 is fixedly connected to the inner wall of the fixed block 204, the outer wall of the clamping block 206 is slidably connected to the inner wall of the fixed block 204, the clamping block 206 is engaged with the groove 212, one end of the spring B210 is fixedly connected to the inner wall of the moving rod 208, the other end of the spring B210 is fixedly connected to the outer wall of the limit block 211, the outer wall of the limit block 211 is slidably connected to the inner wall of the moving rod 208, and the limit block 211 is engaged with the clamping groove 207.

[0027] The above solution is adopted: by pushing the block on the outer wall of the card block 206 downward, the card block 206 is disengaged from the group of grooves 212, the limit of the rotating shaft 202 can be released, and the sleeve rod 203 and the rotating shaft 202 are turned outward. When the sleeve rod 203 is turned to the position corresponding to another group of grooves 212 on the rotating shaft 202, the spring A205 can drive the card block 206 to pop up and engage with the group of grooves 212 due to its own elastic force, so that the sleeve rod 203 remains fixed in the tilted state; then, by pressing the limit block 211, the sleeve rod 203 can be The moving rod 208 is pulled outward to extend the distance between the moving rod 208 and the sleeve rod 203, and the limit block 211 is popped out by the elastic force of the spring B210, and is engaged with another set of slots 207, so that the moving rod 208 and the sleeve rod 203 can be fixed. At this time, during the downhill process, the rotating wheel 209 under the moving rod 208 is in contact with the ground, and the moving rod 208 and the sleeve rod 203 generate an upward supporting force for the hopper 3, thereby avoiding the risk of the overall center of gravity of the device moving forward and possibly causing tipping when going downhill.

[0028] like Figures 5 to 7 As shown, the stabilizing mechanism 4 includes a pull rod 401, the inner wall of the pull rod 401 is elastically connected with a protrusion 408 through a spring C407, a through groove 5 is provided on the rear end outer wall of the base 1, a block 405 is hingedly connected to the outer wall of the pull rod 401 through a connecting rod 402, a slider 403 is slidably connected to the inner wall of the block 405, an inclined groove 406 is provided on the front end outer wall of the slider 403, a bottom plate 404 is fixedly connected to the bottom outer wall of the slider 403, two sets of guide columns 409 are fixedly connected to the inner wall of the base 1, and the pull rod 401 and the base 1 is slidably connected to the inner wall of the block 405, one end of the connecting rod 402 is hinged to the outer wall of the block 405, the other end of the connecting rod 402 is hinged to the outer wall of the pull rod 401, the guide column 409 is slidably connected to the inner wall of the inclined groove 406, one end of the spring C407 is fixedly connected to the outer wall of the protrusion 408, the other end of the spring C407 is fixedly connected to the inner wall of the pull rod 401, the outer wall of the protrusion 408 is slidably connected to the inner wall of the pull rod 401, the protrusion 408 is clamped with the through groove 5, and the block 405 is slidably connected to the inner wall of the base 1.

[0029] The above scheme is adopted: by pressing the protrusion 408 to make it disengage from one group of through grooves 5, the spring C407 is forced to shrink, and the limit of the pull rod 401 can be released, and the pull rod 401 is pulled forward and backward. When the pull rod 401 moves to the position where the protrusion 408 corresponds to the position of the other group of through grooves 5, the protrusion 408 pops out due to the elastic force of the spring C407 and engages with the through groove 5, so that the pull rod 401 can be fixed; when the pull rod 401 is pulled outward, the two groups of connecting rods 402 are turned over, and the block 405 is driven to move horizontally toward the middle in the inner wall of the base 1. At this time, the slider 403 moves synchronously with the block 405 to the middle, because the guide column 409 is always kept in the inclined groove 406 When the pull rod 401 is pushed inward, the two groups of blocks 405 and the slider 403 can be driven to move horizontally to both sides at the same time through the connecting rod 402. At this time, under the guidance of the guide column 409, the slider 403 moves downward at the same time, so that the two groups of bottom plates 404 move downward and contact and fit with the ground, thereby increasing the contact area with the ground. The device is more stable when placed for unloading, and the problem of the device being easy to shake during the unloading process due to the poor stability after the universal wheel is locked will not occur.

[0030] The working principle and use process of this utility model:

[0031] The operator can place the building materials in the hopper 3 and push the handle on the upper rear end of the base 1 to push the device to the detection location through the four sets of universal wheels under the base 1. When the device is pushed to the downhill section, the operator can push the block on the outer wall of the block 206 downward to move the block 206 downward, and the spring A205 is forced to shrink, and the block 206 is out of contact with a group of grooves 212, and then the sleeve rod 203 is turned outward to drive the rotating shaft 202 to rotate synchronously. When the rotating shaft 202 rotates to a position corresponding to the other group of grooves 212, the block 206 pops up upward due to the elastic force of the spring A205 and engages with the group of grooves 212, so as to limit the sleeve rod 203; then the limit block 211 can be pressed downward, and the spring B21 0 is contracted by force, and the limit block 211 is out of contact with a group of slots 207, so that the moving rod 208 can be pulled outward, so that the distance between the moving rod 208 and the sleeve rod 203 becomes longer. When the moving rod 208 moves to the position where the limit block 211 corresponds to the position of the other group of slots 207, the spring B210 drives the limit block 211 to pop out due to its own elastic force and engages with the slot 207, so that the moving rod 208 and the sleeve rod 203 are fixed. At this time, the sleeve rod 203 is in an inclined state. When the device is pushed on a downhill section, the wheel 209 under the moving rod 208 is in contact with the ground and can rotate. The moving rod 208 and the sleeve rod 203 support the front end of the device, avoiding the problem that the overall center of gravity of the device is forward when going downhill, which is easy to tip over.

[0032] When the device is moved to the detection location, the universal wheel can be locked, and the protrusion 408 can be pressed to make it disengage from the through groove 5, and then the pull rod 401 can be pushed inward. By flipping the two sets of connecting rods 402, the two sets of blocks 405 and the slider 403 can be driven to move to both sides at the same time. The inclined groove 406 on the outer wall of the slider 403 is squeezed by the guide column 409, so that the slider 403 can move downward along the inner wall of the block 405 while moving to both sides, and move to a state where the bottom plate 404 is in contact with the ground. At this time, the spring C407 drives the protrusion 408 to pop up upward due to the elastic force and engage with the other set of through grooves 5, so that the pull rod 401 can be limited, thereby fixing the positions of the two sets of connecting rods 402, the slider 403 and the bottom plate 404, thereby improving the stability of the device and avoiding the problem that the universal wheel is not stable enough after being locked, and the device may still shake during the feeding process.

[0033] After the bottom plate 404 is fitted to the ground, the baffles on both sides of the hopper 3 can be opened to discharge the building materials in the hopper 3. After the discharge is completed, the protrusion 408 can be pressed to pull the pull rod 401 outward to move the two groups of blocks 405 toward the middle, and the inclined groove 406 on the outer wall of the slider 403 drives the bottom plate 404 to move upward under the action of the guide column 409, so that the bottom plate 404 can be separated from the ground, and the bottom plate 404 can be limited by the engagement of the protrusion 408 with the other group of through grooves 5. At this time, the universal wheel is unlocked and the device can be pushed again for transportation.
