[0004] Therefore, in order to improve the work efficiency and accuracy of sweet sorghum harvesting integrated machine in the squeezing and throwing process, it is necessary to develop a new type of material conveying device which can adjust the materials in the width direction.

[0029] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present disclosure.

[0030] Figure 1 The structure diagram of the material roller set and the conveying mechanism for gathering sweet sorghum is shown. Figure 1 As shown in the drawings, the present embodiment provides a material conveying device for a sweet sorghum harvesting all-in-one machine, which comprises a frame 1, a conveying mechanism 2 and a material roller set 3. The conveying mechanism 2 is arranged in the frame 1. The material roller set 3 is rotatably arranged in the frame 1 and above the conveying mechanism 2. The material roller set 3 and the conveying mechanism 2 clamp the sweet sorghum along the length direction of the conveying mechanism 2 to convey the sweet sorghum, and the material roller set 3 can also spread or gather the conveyed sweet sorghum in the width direction of the conveying mechanism 2.

[0031] The material conveying device can adapt sweet sorghum output by a first pressing device (an upstream processing device) to the receiving range of a second pressing device (a downstream processing device) and convey the sweet sorghum into the second pressing device (the downstream processing device), thereby improving the working efficiency of the second pressing device. In the throwing process, the material conveying device can adapt the pressed sweet sorghum to the receiving range of a throwing device (a downstream processing device) and convey the sweet sorghum into the throwing device, thereby reducing material waste and improving the efficiency and accuracy of the overall operation.

[0032] Figure 2 The structure diagram of the material roller 31 is shown. Figure 2 And in combination with Figure 1 As shown, the material roller group 3 comprises at least two material rollers 31 arranged at intervals along the length direction of the conveying mechanism 2, each material roller 31 comprises a roller body 311 rotatably arranged in the frame body 1, and a first spiral blade 312 and a second spiral blade 313 are wound on the outer circumferential surface of the roller body 311, and the spiral directions of the first spiral blade 312 and the second spiral blade 313 are opposite. On the one hand, the first spiral blade 312 and the second spiral blade 313 can produce extrusion on the sweet sorghum relative to the smooth material roller 31, so as to ensure that the sweet sorghum can be stably conveyed along the length direction of the conveying mechanism 2 under the joint clamping of the conveying mechanism 2 and the material roller group 3. On the other hand, the opposite spiral directions of the first spiral blade 312 and the second spiral blade 313 can promote the sweet sorghum to spread or gather in the width direction of the conveying mechanism 2 while being conveyed along the length direction of the conveying mechanism 2.

[0033] Specifically, Figure 3 The structure diagram of the material roller group 3 and the conveying mechanism 2 for gathering sweet sorghum is shown. Figure 3 As shown and in combination with Figure 1 And Figure 2 The structure of the first spiral blade 312 and the second spiral blade 313 at the intersection thereof from the input end to the output end of the conveying mechanism 2 is herringbone-shaped and realizes gathering of the sweet sorghum in the width direction of the conveying mechanism 2 through rolling of the roller body 311. As shown in Figure 1 And Figure 2 The structure of the first spiral blade 312 and the second spiral blade 313 at the intersection thereof from the input end to the output end of the conveying mechanism 2 is inverted herringbone-shaped and realizes spreading of the sweet sorghum in the width direction of the conveying mechanism 2 through rolling of the roller body 311.

[0034] As Figure 3 and shown in Figure 1 and Figure 2 , wherein the first spiral blade 312 and the second spiral blade 313 are mirror-symmetric about a selected cross-section of the roller body 311, the selected cross-section being a cross-section perpendicular to the central axis of the roller body 311 and passing through the midpoint of the roller body 311 in the width direction, so that the sweet sorghum transported along the length direction of the conveying mechanism 2 is evenly spread or gathered.

[0035] Further, the frame body 1 comprises a first guard plate 13 and a second guard plate 14 symmetrically arranged, the chain plate 21 is installed between the first guard plate 13 and the second guard plate 14, and the material roller set 3 is also installed between the first guard plate 13 and the second guard plate 14. The first guard plate 13 and the second guard plate 14 symmetrically arranged can effectively prevent the material from deviating or scattering during the conveying process.

[0036] Continuing to refer to Figure 3 and shown in Figure 1 and Figure 2 , the thickness of the first guard plate 13 and the thickness of the second guard plate 14 gradually increase along the length direction of the conveying mechanism 2, so as to cooperate with the material roller set 3, so that the sweet sorghum transported along the length direction of the conveying mechanism 2 can be effectively gathered.

[0037] As Figure 1 shown, the material conveying device further comprises a transmission mechanism 4 arranged in the frame body 1 and connected with the plurality of material rollers 31. The transmission mechanism 4 is used to transmit the power generated by the power device of the sweet sorghum harvesting integrated machine to each material roller 31, and make the linear speed of each material roller 31 decrease or increase along the conveying direction of the conveying mechanism 2, so that the speed of the sweet sorghum transported along the length direction of the conveying mechanism 2 gradually decreases or increases. When the first spiral blade 312 and the second spiral blade 313 of the material roller 31 spread the transported sweet sorghum, if the speed of the transported sweet sorghum gradually decreases, the sweet sorghum will not only spread in the width direction of the conveying mechanism 2, but also accumulate (grow) in the width direction of the conveying mechanism 2, so as to utilize the processing effect of the downstream processing equipment. When the first spiral blade 312 and the second spiral blade 313 of the material roller 31 gather the transported sweet sorghum, if the speed of the transported sweet sorghum gradually increases, the sweet sorghum will not only gather in the width direction of the conveying mechanism 2, but also enter the downstream processing equipment faster, thereby reducing the risk of blockage and leakage of the sweet sorghum.

[0040] Further, the frame 1 comprises a first sliding groove 11 rotatably accommodating the first end of the cloth roller 31, and a second sliding groove 12 rotatably accommodating the second end of the cloth roller 31, the first sliding groove 11 and the second sliding groove 12 are strip-shaped holes, and the first sliding groove 11 and the second sliding groove 12 can provide a moving space for the cloth roller 31, so that the distance between the cloth roller 31 and the conveying mechanism 2 can be changed according to the thickness of the sweet sorghum therebetween, thereby making the material conveying device better adapt to the conveying of sweet sorghum.

[0041] Preferably, the material conveying device further comprises an elastic assembly (not shown) arranged on the frame 1 and connected to the cloth roller 31, the elastic assembly controls the distance between the cloth roller 31 and the conveying mechanism 2 by its own elastic force, so as to control the cloth roller 31 to effectively clamp the sweet sorghum in cooperation with the conveying mechanism 2.
