[0037] Embodiment 1

[0038] The material transportation device provided by the present application can be applied to a seed melon harvester. The material transportation device can transport the rinds of seed melons on the field to a vehicle for loading, so that a large amount of rinds can be transported by the vehicle to a treatment site for subsequent treatment operations, so that the rinds can be reasonably utilized.

[0039] See Figures 1 to 4As shown in the figure, the material transportation device provided by the present application includes a material loading mechanism and a material pushing mechanism. The material loading mechanism includes a first loading plate 101 and a second loading plate 102, and the second loading plate 102 can swing relative to the first loading plate 101; the material pushing mechanism includes a sprocket drive assembly and a plurality of pushing plates 103; the sprocket drive assembly is linked and bent with the material loading mechanism; the plurality of pushing plates 103 are all connected to the sprocket drive assembly, and the plurality of pushing plates 103 are arranged at intervals along the length direction of the sprocket drive assembly to push the material to move along the first loading plate 101 and the second loading plate 102.

[0040] Specifically, when transporting materials, the first loading plate 101 and the second loading plate 102 are used to carry the materials. Among them, the first loading plate 101 is horizontally placed on the ground, and the end of the first loading plate 101 away from the second loading plate 102 is the starting end of the transportation path, and the material can be placed on the first loading plate 101 from this place. The second loading plate 102 can swing relative to the first loading plate 101, and the end of the second loading plate 102 away from the first loading plate 101 is the terminal end of the transportation path, that is, the angle between the second loading plate 102 and the first loading plate 101 can be correspondingly adjusted according to the height of the vehicle transporting the material, so as to adjust the height of the transportation terminal to be flush with the height of the vehicle's carriage, so that the material can finally be transported to the vehicle's carriage.

[0041] The material pushing mechanism includes a sprocket drive assembly and a plurality of pushing plates 103. The sprocket drive assembly can drive the plurality of spaced pushing plates 103 to move along the first loading plate 101 and the second loading plate 102, so that the material can be pushed from the starting end of the transportation path, through the first loading plate 101 and the second loading plate 102, and finally pushed to the terminal end of the transportation path. And due to the bendable characteristic of the sprocket drive assembly, it can be deformed along with the swing of the first loading plate 101 and the second loading plate 102 to ensure that the pushing plate 103 can always fit the bearing surfaces of the first loading plate 101 and the second loading plate 102, so as to realize the transportation of the material.

[0042] The material transportation device provided by the present application can correspondingly adjust the height of the terminal of the transportation path of the material loading mechanism according to the height of the vehicle transporting the material, so that the melon rinds of the seed melons in the field can be collected, transported and loaded onto the vehicle, so that the melon rinds can be reasonably utilized and the waste of resources can be reduced.

[0043] In an optional solution of this embodiment, specifically, both ends of the pushing plate 103 are connected with a sprocket drive assembly, and the two sprocket drive assemblies jointly drive the pushing plate 103 to move forward, so that the pushing plate 103 is not easily bent and skewed during the pushing process. Further, as Figure 2As shown, the sprocket drive assembly includes a drive chain 104, a driving sprocket 105, and a driven sprocket 106. The driving sprocket 105 is installed at one end of the first loading plate 101 away from the second loading plate 102, and the driven sprocket 106 is installed at one end of the second loading plate 102 away from the first loading plate 101. A plurality of pushing plates 103 are all connected to the drive chain 104. The drive chain 104 is wound around the driving sprocket 105 and the driven sprocket 106, and the driving sprocket 105 and the driven sprocket 106 divide the drive chain 104 into a driving portion 107 and a return portion 108.

[0044] More specifically, the driving portion 107 is located on the front surface of the first loading plate 101 (the loading surface of the first loading plate 101) and the front surface of the second loading plate 102 (the loading surface of the second loading plate 102), and the return portion 108 is located on the back surface of the first loading plate 101 (the side opposite to the loading surface of the first loading plate 101) and the back surface of the second loading plate 102 (the side opposite to the loading surface of the second loading plate 102). That is to say, the plurality of pushing plates 103 flowing to the front surfaces of the first loading plate 101 and the second loading plate 102 are used to transport the material from the starting end of the transportation path to the terminal end. After the feeding of the plurality of pushing plates 103 is completed, the plurality of pushing plates 103 can flow back from the terminal end of the transportation path to the starting end along the back surfaces of the first loading plate 101 and the second loading plate 102 for the next round of pushing process.

[0045] In an alternative embodiment of this example, as Figure 3 shown, the sprocket drive assembly further includes a first pressing member 109. The first pressing member 109 is disposed in the middle of the driving portion 107, and the position of the first pressing member 109 corresponds to the position of the rotating shaft between the first loading plate 101 and the second loading plate 102. The first pressing member 109 is used to press the driving portion 107 to divide the driving portion 107 into two mutually swinging parts. When the second loading plate 102 swings relative to the first loading plate 101, it can drive the driving portion 107 of the drive chain 104 to bend synchronously, and the setting of the first pressing member 109 makes its bending center opposite to the swinging center, so that the drive chain 104 can be deformed correspondingly with the swing and remain in a taut state, avoiding the occurrence of chain-off phenomenon.

[0046] Similarly, the sprocket drive assembly further includes a second pressing member 110. The second pressing member 110 is disposed in the middle of the return portion 108, and the position of the second pressing member 110 corresponds to the position of the rotating shaft between the first loading plate 101 and the second loading plate 102; the second pressing member 110 is used to press the return portion 108 to divide the return portion 108 into two mutually swinging parts. When the second loading plate 102 swings relative to the first loading plate 101, it can drive the return portion 108 of the drive chain 104 to bend synchronously, and the setting of the second pressing member 110 makes its bending center opposite to the swinging center, so that the drive chain 104 can be deformed correspondingly with the swing and remain in a taut state, avoiding the occurrence of chain-off phenomenon.

[0047] In an alternative solution of this embodiment, the pressing surface of the first pressing member 109 is an arc surface. When the first pressing member 109 presses on the driving portion 107, the friction between the two is small and will not affect the movement of the driving chain 104. Similarly, the pressing surface of the second pressing member 110 is an arc surface. When the second pressing member 110 presses on the return portion 108, the friction between the two is small and will not affect the movement of the driving chain 104.

[0048] In an alternative solution of this embodiment, such as Figure 3 and Figure 4 shown, the pusher mechanism further includes a guide rail assembly. The guide rail assembly includes a first guide rail 111 and a second guide rail 112. The first guide rail 111 is installed on the first loading plate 101, and the second guide rail 112 is installed on the second loading plate 102. The sprocket drive assembly moves along the guiding direction of the first guide rail 111 and the second guide rail 112. The first guide rail 111 and the second guide rail 112 can guide and limit the movement of the sprocket drive assembly, preventing the occurrence of chain derailment. Moreover, the first guide rail 111 can separate the moving sprocket drive assembly from the first loading plate 101, and the second guide rail 112 can separate the moving sprocket drive assembly from the second loading plate 102, avoiding wear on the first loading plate 101 and the second loading plate 102 caused by the moving sprocket drive assembly.

[0049] In an alternative solution of this embodiment, the loading mechanism further includes a flexible transition plate 113. One end of the flexible transition plate 113 is connected to the first loading plate 101, and the other end of the flexible transition plate 113 is connected to the second loading plate 102. The flexible transition plate 113 is specifically arc-shaped to provide an arc transition at the docking portion of the first loading plate 101 and the second loading plate 102. Moreover, the curvature of the flexible transition plate 113 can be adjusted according to the angle between the first loading plate 101 and the second loading plate 102, and it is not easy to produce jamming when the pusher plate 103 pushes the material onto the flexible transition plate 113.

[0050] Embodiment Two

[0051] The material transportation device in this second embodiment is an improvement based on the above embodiment. The technical content disclosed in the above embodiment will not be repeatedly described, and the content disclosed in the above embodiment also belongs to the content disclosed in this second embodiment.

[0052] Such as Figure 1 and Figure 2As shown, in an alternative solution of this embodiment, the material transportation device further includes a conveying frame. The conveying frame includes a swing rotating shaft 114, a first frame 115, and a second frame 116. The first frame 115 and the second frame 116 are connected by the swing rotating shaft 114 so that the second frame 116 can swing relative to the first frame 115. The first loading plate 101 is installed on the first frame 115, and the second loading plate 102 is installed on the second frame 116. The sprocket drive assembly is connected to the first frame 115 and the second frame 116. That is to say, the conveying frame serves as the main structure, which can install and fix the first loading plate 101, the second loading plate 102, and the sprocket drive assembly. Moreover, the hinged first frame 115 and second frame 116 enable the first loading plate 101 and the second loading plate 102 to swing relative to each other.

[0053] In an alternative solution of this embodiment, the conveying frame further includes a discharge port 117, and the discharge port 117 is located at one end of the second frame 116 away from the first frame 115.

[0054] In this embodiment, when the pushing plate 103 pushes the material to the end of the transportation path, the throwing force generated by the pushing plate 103 can cause the material to be thrown out from the discharge port 117 along a parabolic direction. The discharge port 117 is specifically cylindrical and connected to the second frame 116. The discharge port 117 can play a role in guiding the material so that the material can fall into the carriage of the vehicle.

[0055] In an alternative solution of this embodiment, as Figure 4 shown, the first frame 115 includes two first side plates 118 arranged at intervals, and the first loading plate 101 and the pushing mechanism are located between the two first side plates 118. A first baffle 119 is arranged between the first side plate 118 and the pushing plate 103, and one end of the first baffle 119 close to the first loading plate 101 is bent towards the direction close to the pushing plate 103. When the pushing plate 103 pushes the material on the first loading plate 101 forward, the two first baffles 119 on both sides can play a role in converging inward, preventing the material from being pushed outside the coverage of the pushing plate 103 and causing the material to accumulate in the corner at the connection between the first side plate 118 and the first loading plate 101.

[0056] Similarly, the second frame 116 includes two second side plates 120 arranged at intervals, and the second loading plate 102 and the pushing mechanism are located between the two second side plates 120. A second baffle 121 is arranged between the second side plate 120 and the pushing plate 103, and one end of the second baffle 121 close to the second loading plate 102 is bent towards the direction close to the pushing plate 103. When the pushing plate 103 pushes the material on the second loading plate 102 forward, the two second baffles 121 on both sides can play a role in converging inward, preventing the material from being pushed outside the coverage of the pushing plate 103 and causing the material to accumulate in the corner at the connection between the second side plate 120 and the second loading plate 102.
