An auxiliary frame 3 is fixed on the mounting frame 2. The front and back of the inner cavity of the auxiliary frame 3 are provided with chambers, and an extension frame 4 is slidably arranged in the chamber. A transmission wheel 5 is rotatably mounted on the left side of the inner cavity of the auxiliary frame 3 and the right side of the inner cavity of the extension frame 4. A conveyor belt 6 for conveying building materials is connected to the transmission wheel 5. A first motor 7 is embedded in the front of the mounting frame 2. The output shaft of the first motor 7 and one of the sets of transmission wheels 5 are fixed with a conveyor belt that can transmit power through the belt. A cylinder 10 is symmetrically mounted on the other side of the top of the push frame 1, rotating in the front-back direction. The piston rod of the cylinder 10 is mounted on a drive seat 9, which is fixed on the auxiliary frame 3. The auxiliary frame 3 and the push frame 1 are equipped with drive components that work with the extension frame 4 and the conveyor belt 6. By setting the drive components, the overall size of the device can be freely adjusted according to the conveying needs, so that the device can quickly convey building materials to a suitable position. Moreover, it can quickly form an adaptive tension positioning structure according to the change of the inclination angle of the auxiliary frame 3, so that the device can still maintain a stable state after the overall extension, thus improving the overall applicability of the device.

[0023] In a preferred embodiment of this invention, the drive assembly includes a drive frame 11 rotatably mounted on the front and back of the auxiliary frame 3.

A second motor 14 is fixed to the right side of the front of the auxiliary frame 3 via a bracket. A gear 15 is fixed to the output shaft of the second motor 14. Multiple sets of fasteners that mesh with the gear 15 are sequentially fixed along the left-right direction on the front bottom of the extension frame 4. The fixed tooth 16 and the auxiliary frame 3 have a transverse groove on the front of the bottom that communicates with one of the chambers and allows the fixed tooth 16 to pass through. The design of the second motor 14, gear 15 and fixed tooth 16 can quickly extend the extension frame 4 to a suitable position. The design of the electric push rod 12, drive frame 11 and auxiliary wheel 13 can control the overall tension of the conveyor belt 6 so that the state of the conveyor belt 6 can be adjusted in real time after the extension frame 4 moves, so that it can still be kept taut. This allows for free adjustment of the overall size of the device according to the conveying needs.

[0024] As a preferred embodiment of this utility model, the drive assembly further includes side plates 24 rotatably mounted on the front and back of the push frame 1. Universal wheels are provided around the bottom of the push frame 1 and at the bottom of the side plates 24. A vertical plate is fixed to the outer side of the top of the side plates 24, and a winding drum 23 and a third motor 22 are rotatably mounted and fixed on the vertical plate along the left and right directions, respectively. The output shaft of the third motor 22 and the winding drum 23 are fixed to each other. A steel wire rope 20 is wound on the winding drum 23.

The side plate 24 is provided with guide wheels 21 to guide the steel wire rope 20. U-shaped locking frames 25 are inserted on the inner side of the top of the side plate 24 and on the push frame 1. The design of the third motor 22, the winding drum 23, the fixed shaft 17, the positioning frame 18 and the steel wire rope 20 is to quickly form an adaptive pulling and positioning structure according to the change of the tilt angle of the auxiliary frame 3, so that the device can still maintain a stable state after the overall extension.

[0025] As a preferred embodiment of this utility model, the top of the inner cavity of the auxiliary frame 3 is rotatably equipped with multiple sets of idlers that cooperate with the conveyor belt 6 in the left-right direction. The front and back of the extension frame 4 are sequentially opened with multiple sets of round holes 28 in the left-right direction. A cylinder 27 is inserted into each of the two sets of round holes 28 on the right side. A fixed roller 26 that cooperates with the conveyor belt 6 is rotatably installed on the side of the cylinder 27 that is close to each other. A screw hole is opened on the side of the cylinder 27 that is far from each other. A fixing bolt 29 is threaded into each set of screw holes. The protruding end of each set of fixing bolts 29 is attached to the extension frame 4. The design of the round holes 28, cylinders 27, fixing rollers 26, screw holes and fixing bolts 29 can form a support structure for the conveyor belt 6 on the inner side of the extension frame 4 when the extension frame 4 extends outward, so as to cooperate with the idlers to assist in the stable conveying of building materials.

[0026] As a preferred embodiment of this utility model, each positioning frame 18 has a locking nut 19 engaged with an external thread at its other end. The design of the locking nut 19 can limit the positioning frame 18 and prevent the positioning frame 18 from easily detaching from the fixed shaft 17.

[0027] As a preferred embodiment of this utility model, each set of side plates 24 has multiple sets of placement slots sequentially opened on the top along the front-back direction. The placement slots are designed to hold some counterweights or counterweights to make the device more stable. The right side of the front and back of the push frame 1, which is away from the side plate 24, is fixed with a protruding plate, and each set of protruding plates is provided with an insertion hole. The protruding plate and insertion hole are designed to allow the ground nail to pass through, making the device more stable and preventing the device from tipping over due to excessive tilt angle.

[0028] As a preferred embodiment of this utility model, the top left side of the push frame 1 is symmetrically provided with positioning square holes for inserting the U-shaped locking frame 25 in the front-back direction. The design of the positioning square holes is so that when the side plate 24 is rotated and stored and is attached to the push frame 1, the side plate 24 can be fixed by inserting the U-shaped locking frame 25 and the positioning square holes.

[0029] The working principle of this utility model:

[0030] refer to Figures 1 to 4 The user activates the second motor 14 and electric push rod 12 via the controller. The electric push rod 12 drives the drive frame 11 to swing, which in turn drives the auxiliary wheel 13 to swing synchronously towards the auxiliary frame 3, releasing the tension of the conveyor belt 6. The second motor 14 then drives the gear 15 to rotate. The meshing of the gear 15 and the fixed teeth 16 drives the extension frame 4 to move outward until it reaches the appropriate position according to the material conveying needs. Simultaneously, the electric push rod 12 controls the position change of the auxiliary wheel 13, restoring the tension of the conveyor belt 6. The user then selects the number of fixed rollers 26 based on the position of the exposed circular holes 28 and inserts them into the holes. The cylinders 27 are then engaged within the holes 28. The engagement of the fixing bolts 29 and screw holes secures the cylinders 27. The fixed rollers 26 provide stable support for the conveyor belt 6. Finally, the user activates the cylinder 10 and the third motor 22 via the controller. 22 drives the winding drum 23 to reverse, releasing the wire rope 20, allowing the cylinder 10 to drive the auxiliary frame 3 to swing stably until the auxiliary frame 3 is adjusted to a suitable tilt angle. At this time, the user moves the U-shaped locking bracket 25 to disengage it from the side plate 24 and the positioning square hole, releasing the locking state of the side plate 24, and pulls the side plate 24 outward until it rotates ninety degrees. Then, the user inserts the U-shaped locking bracket 25 into the preset groove of the side plate 24 and the push frame 1 to position the side plate 24. When the steel wire rope 20 is in a loose state, the user can drive the winding drum 23 to rotate forward via the third motor 22 to wind up the steel wire rope 20 until it is pulled to a taut state. This quickly forms an adaptive tension positioning structure so that the device can remain stable after the overall extension. At this time, the user can start the first motor 7 via the controller, and with the assistance of the pulley 8, drive the conveyor belt 6 to transmit power, thereby quickly transporting the building materials to the required position.
