DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0028] Example 1

[0029] A splicable conveyor for transporting materials, such as Figure 1-Figure 3As shown, it includes a support frame 1, a wheel 2, a first pulley 3, a first flat belt 4, a driving motor 5 and a splicing mechanism 6. There are two support frames 1, and the two support frames 1 are distributed left and right. The two support frames 1 are in contact with each other. The left and right sides of the bottom of the support frame 1 are symmetrically connected to the wheels 2 in a front and rear rotational manner. The wheels 2 facilitate the movement of the conveyor. The left and right sides of the support frame 1 are rotatably connected to the first pulleys 3. The first flat belt 4 is wound between the first pulleys 3 on the left and right sides of the support frame 1 on the left side, and the first flat belt 4 is also wound between the first pulleys 3 on the left and right sides of the support frame 1 on the right side. The first flat belt 4 can transport materials. The driving motor 5 is connected to the left front side of the support frame 1 on the left side, and the driving motor 5 is also connected to the left front side of the support frame 1 on the right side. The output shaft of the driving motor 5 on the left side is connected to the front side of the first pulley 3 on the far left, and the output shaft of the driving motor 5 on the right side is connected to the front side of the third first pulley 3 from left to right. The support frame 1 is provided with a splicing mechanism 6 for splicing different support frames 1 together.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the splicing mechanism 6 includes a fixed plate 61, an electromagnet 62, a guide rod 63, a first sliding rod 64, a first return spring 65 and a locking assembly. The bottom wall of the support frame 1 is welded with a fixed plate 61, the lower right side of the fixed plate 61 is fixedly connected to the electromagnet 62, the right side of the electromagnet 62 is fixedly connected to the guide rod 63, the guide rod 63 is fixedly connected to the lower side of the fixed plate 61, the first sliding rod 64 is slidably connected to the guide rod 63, the first return spring 65 is connected between the right side of the first sliding rod 64 and the right part of the guide rod 63, the first return spring 65 is wound on the guide rod 63, and the left side of the fixed plate 61 is connected to the locking assembly, which can splice two different support frames 1 together.

[0031] like Figure 5 As shown, the locking assembly includes a connecting block 66, a rotating block 67 and a torsion spring 68. Connecting blocks 66 are welded on the front and rear sides of the left side of the fixed plate 61. The front connecting block 66 is rotatably connected to the rotating block 67, and the rear connecting block 66 is also rotatably connected to the rotating block 67. Slots are provided on the front and rear sides of the right side of the fixed plate 61. The rotating block 67 can be rotated to engage with the slots on the fixed plate 61 on another support frame 1, so that different support frames 1 can be spliced. The front and rear sides of the right side of the fixed plate 61 are both inclined surfaces, which can better squeeze and rotate the rotating block 67 on the other support frame 1. Torsion springs 68 are connected between the upper and lower sides of the rotating block 67 and the connecting block 66. The torsion springs 68 are all wound around the connecting block 66, and the torsion spring 68 can rotate and reset the connecting block 66.

[0032] When people need to transport a large amount of materials, this conveyor can be used to achieve this. First, people move the support frame 1 to the specified position through the wheels 2. Then people need to splice multiple support frames 1, so that people can transport a large amount of materials. When people need to splice multiple support frames 1, people insert the fixed plate 61 on another support frame 1 between the two rotating blocks 67 on the current support frame 1. Since the right side of the fixed plate 61 is sharp, it can squeeze the rotating block 67 on the current support frame 1 to rotate. At this time, the torsion spring 68 is twisted, and the rotating block 67 will be stuck in the slot opened on the fixed plate 61 on the other support frame 1 after rotation. Then people use the power supply to energize the electromagnet 62, and then the electromagnet 62 will release the current, so that the first sliding rod 64 will be stuck in the rotating block 67. At this time, the first return spring 65 is compressed, so that different support frames 1 can be spliced. After the splicing is completed, people can turn on the drive motor 5. The output shaft of the driving motor 5 rotates to drive the first pulley 3 and the first flat belt 4 to rotate. The rotation of the first flat belt 4 can transport materials, so that a large amount of materials can be transported. After the transportation is completed, people turn off the driving motor 5, and then people separate the power supply from the electromagnet 62. At this time, the electromagnet 62 stops releasing current, and then the first sliding rod 64 is separated from the rotating block 67 on the current support frame 1 under the action of the first reset spring 65, and then the rotating block 67 is released, and then the rotating block 67 is reversed and reset under the action of the torsion spring 68. The reverse rotation of the rotating block 67 will push the fixed plate 61 on another support frame 1 to move, so that the slot on the fixed plate 61 is separated from the rotating block 67, and then people can disassemble different support frames 1. Repeat the above operation to splice different support frames 1 through the fixed plate 61 and the rotating block 67, so that people can transport a large amount of materials, which can improve the material transportation efficiency and reduce the time cost of material transportation.

[0033] Example 2

[0034] On the basis of Example 1, Figure 1 , Figure 3 and Figure 6 As shown, it also includes an auxiliary mechanism 7 for positioning the support frame 1, the auxiliary mechanism 7 includes a first fixed rod 71, a second fixed rod 72, a sliding bevel sleeve 73 and a second return spring 74, the first fixed rod 71 is welded on the left side of the support frame 1, the second fixed rod 72 is connected to the right side of the support frame 1, the second fixed rod 72 is slidably connected to the sliding bevel sleeve 73, the sliding bevel sleeve 73 can position the first fixed rod 71 on another support frame 1, the second return spring 74 is connected between the inner right wall of the sliding bevel sleeve 73 and the left side of the support frame 1, and the second return spring 74 is wound on the second fixed rod 72.

[0035] When people need to position the spliced ​​support frame 1, the first fixing rod 71 on the other support frame 1 will be inserted into the sliding inclined sleeve 73. Then, when the first fixing rod 71 contacts the left wall of the sliding inclined sleeve 73, the first fixing rod 71 continues to move to the right and will push the sliding inclined sleeve 73 to move to the right. At this time, the second return spring 74 is compressed, and the sliding inclined sleeve 73 and the first fixing rod 71 cooperate with each other to position the spliced ​​support frame 1, thereby preventing different support frames 1 from being inaccurately spliced. Subsequently, the materials can be transported. After the transportation is completed, people move the first fixing rod 71 on the other support frame 1 to the left and separate it from the sliding inclined sleeve 73. Then the sliding inclined sleeve 73 moves to the left and resets under the action of the second return spring 74. Repeat the above operation. Through the cooperation of the sliding inclined sleeve 73 and the first fixing rod 71, the support frame 1 can be positioned, thereby preventing different support frames 1 from shifting when splicing.

[0036] like Figure 7 and Figure 8 As shown, it also includes a transmission mechanism 8 for improving the smoothness of material transportation. The transmission mechanism 8 includes a rotating rod 81, a second sliding rod 82, a buckle 83, a third return spring 84, a second pulley 85, a second flat belt 851 and a transmission assembly. The front and rear sides of the upper right part of the left support frame 1 are both rotatably connected with the rotating rod 81, and the front and rear sides of the upper left part of the right support frame 1 are also rotatably connected with the rotating rod 81. The second sliding rod 82 is slidably connected between the two rotating rods 81 on the left, and the second sliding rod 82 is slidably connected between the two rotating rods 81 on the right. The movable rod 81 is slidably connected with a buckle 83, and the buckle 83 is buckled with the second sliding rod 82. The buckle 83 can play a role in locking the second sliding rod 82. A third return spring 84 is connected between the buckle 83 and the rotating rod 81, and the third return spring 84 is wound on the buckle 83. The second sliding rod 82 is sleeved with a second pulley 85, and a second flat belt 851 is wound between the two second pulleys 85. A transmission assembly is connected between the front and rear sides of the second first pulley 3 from left to right and the right rotating rod 81, and the transmission assembly enables the rotating rod 81 to rotate automatically.

[0037] like Figure 8 As shown, the transmission assembly includes a third pulley 86 and a third flat belt 87. The third pulley 86 is connected to the front and rear sides of the second first pulley 3 from left to right, and the third pulley 86 is also connected to the rotating rod 81 on the right side. The third flat belt 87 is wound between the two third pulleys 86 on the front side, and the third flat belt 87 is also wound between the two third pulleys 86 on the rear side.

[0038] When people need to improve the smoothness of material transportation, first, the first pulley 3 rotates to drive the third pulley 86 and the third flat belt 87 to rotate, the third pulley 86 rotates to drive the rotating rod 81 to rotate, the rotating rod 81 rotates to drive the second sliding rod 82, the second pulley 85 and the second flat belt 851 to rotate, and the rotation of the second flat belt 851 can reduce the gap between the two adjacent first flat belts 4, thereby improving the smoothness of material transportation and reducing the shaking rate of material transportation, and then the material can be transported. After the transportation is completed, when people need to remove the second flat belt 851, people move the buckle 83 inward, at this time the third return spring 84 is stretched, and then when the buckle 83 is separated from the second sliding rod 82 , people can remove the second sliding rod 82, the second pulley 85 and the second flat belt 851, and then can separately store the support frame 1. When people need to transport materials, people re-connect the second sliding rod 82 between the rotating rods 81 on the front and rear sides, and then people release the buckle 83, and then the buckle 83 moves outward and resets under the action of the third reset spring 84, and the buckle 83 is re-entered into the second sliding rod 82. The buckle 83 can position the second sliding rod 82, and the resetting of the second sliding rod 82 drives the second pulley 85 and the second flat belt 851 to reset. Repeating the above operation can reduce the gap between the two first flat belts 4 through the third flat belt 87, thereby improving the smoothness of material transportation.

[0039] like Figure 1 , Figure 3 and Fig. 9 As shown, it also includes a protective mechanism 9 for protecting materials, and the protective mechanism 9 includes a fixed block 91 and a protective plate 92. The front and rear sides of the top wall of the support frame 1 are both symmetrically fixedly connected with fixed blocks 91, a protective plate 92 is connected between the two fixed blocks 91 on the front side of the left support frame 1, and a protective plate 92 is also connected between the two fixed blocks 91 on the front side of the right support frame 1. The protective plate 92 is also connected between the two fixed blocks 91 on the rear side of the left support frame 1, and the protective plate 92 is also connected between the two fixed blocks 91 on the rear side of the right support frame 1. The protective plate 92 can protect the materials.

[0040] When people need to protect materials, the protective plate 92 can achieve this function. The protective plate 92 can prevent the materials from falling, thus protecting the materials.
