Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of sweet sorghum collecting, squeezing, throwing and storing devices, and more specifically, the present invention relates to a sweet sorghum collecting, squeezing, throwing and storing all-in-one machine. Background Art

[0002] The sugar mass of sweet sorghum is generally around 15%-22%. It has strong resistance to drought, waterlogging, salinity, barrenness, and high temperature. The stem height can reach 4-6 meters. The biological yield is high, which can reach 2-3 times that of corn. It can be planted on arid, saline-alkali and barren marginal land. It is considered to be the most promising food crop and energy plant. Even after experiencing extreme weather such as floods, droughts and sandstorms, the output of its core products can still be fully guaranteed. This unique variety of sweet sorghum has the advantages of saline-alkali land improvement and soil restoration, and can effectively form a comprehensive industrial chain development path.

[0003] At present, the harvesting of sweet sorghum mainly relies on traditional agricultural machinery, most of which can only complete a single harvesting function. After harvesting, the sweet sorghum stalks often need to be transported, loaded and unloaded many times and piled for a long time before entering the subsequent juicing and storage. This process is not only inefficient, but also increases labor costs and material losses.

[0004] In the processing of sweet sorghum juice, the existing technology usually directly collects and stores the squeezed juice, lacking the process of further preservation or refining the juice. This not only limits the application scope of sweet sorghum juice, but also may cause the juice to deteriorate due to long-term storage, directly affecting the quality of the final product. Summary of the invention

[0005] In order to solve one or more of the technical problems mentioned above, the present invention provides a sweet sorghum collection, squeezing, throwing and storage all-in-one machine, which can improve the juice squeezing efficiency of sweet sorghum and prevent the sorghum juice from deteriorating.

[0025] The distribution roller group and the first conveyor convey the sweet sorghum along the length of the first conveyor in a clamping manner, wherein each of the distribution rollers in the distribution roller group causes the conveyed sweet sorghum to spread or gather in the width direction of the first conveyor through its own first spiral blade and second spiral blade.

[0026] Furthermore, the conveying device also includes a transmission mechanism disposed in the second frame and connected to the plurality of cloth rollers, the transmission mechanism being used to transmit the power generated by the power device of the motor vehicle to each of the cloth rollers, and causing the linear speed of each of the cloth rollers to decrease or increase along the conveying direction of the first conveyor.

[0027] Furthermore, the crushing and throwing device comprises:

[0053] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0054] Figure 1 The structure diagram of a sweet sorghum collecting, squeezing, throwing and storing machine provided by an embodiment of the present invention is shown. Figure 2 FIG. 2 shows a side view of a sweet sorghum collecting, squeezing, throwing and storing machine provided in this embodiment. Figure 3 FIG. 4 shows a cross-sectional view of the heating assembly 5 and the storage box provided in this embodiment. Figure 1 and Figure 3 As shown, this embodiment provides a sweet sorghum harvesting, squeezing, throwing and storing integrated machine, including a motor vehicle 1, a harvesting device 2, a juice extraction device 3, a storage device 4, a heating component 5 and a crushing and throwing device 7. The harvesting device 2 is arranged on the motor vehicle 1 and is used to harvest sweet sorghum, which belongs to the conventional technology in the field and is not repeated here. The juice extraction device 3 is arranged on the motor vehicle 1, and is used to squeeze the harvested sweet sorghum to obtain sweet sorghum juice. The storage device 4 is arranged on the motor vehicle 1, and is used to collect and store the squeezed sweet sorghum juice. The heating component 5 is arranged in the storage device 4 and is used to heat, sterilize and keep the juice warm. The crushing and throwing device 7 can crush and throw the squeezed sweet sorghum.

[0055] The sweet sorghum collection, squeezing, throwing and storage integrated machine provided in this embodiment integrates at least a harvesting device 2, a juice extraction device 3 and a storage device 4 on the same motor vehicle 1, and can even integrate a crushing and throwing device 7 on the same motor vehicle 1, giving the sweet sorghum collection, squeezing, throwing and storage integrated machine an excellent performance integrating the four functions of harvesting, squeezing, storage and throwing. This setting not only realizes the direct squeezing and efficient collection and storage of sweet sorghum, but also significantly improves the overall efficiency of sweet sorghum juicing by the way that the harvesting and juice extraction devices 3 operate synchronously with the vehicle. It is particularly worth mentioning that the heating component 5 in the sweet sorghum collection, squeezing, throwing and storage integrated machine can perform heat sterilization treatment on the sweet sorghum juice in the storage device 4 and maintain its suitable temperature, effectively solving the problem of juice deterioration that may be caused by a long operation cycle, thereby ensuring the final quality and safety of the sweet sorghum juice and realizing optimization from field to storage.

[0056] Furthermore, the storage device 4 includes a juice receiving hopper 41 disposed below the juice extraction device 3 and used to collect the squeezed sweet sorghum juice, and a storage box 42 connected to the juice receiving hopper 41 and used to receive and store the sweet sorghum juice, wherein the heating assembly 5 includes an electric heating wire (not shown) disposed in the storage box 42 and powered by the power supply device of the motor vehicle 1, or a heating pipe 51 disposed in the storage box 42 and heated by the steam generator of the motor vehicle 1. The storage device 4 utilizes the juice receiving hopper 41 disposed below the juice extraction device 3 and the storage box 42 connected thereto, and this arrangement is intended to efficiently capture and collect the sweet sorghum juice freshly squeezed by the juice extraction device 3. As a key component connecting the juice extraction and storage links, the juice receiving hopper 41 accurately guides the juice to flow into the storage box 42, ensuring smooth collection and proper preservation of the juice. The heating assembly 5 is carefully arranged inside the storage box 42, including two optional solutions: one is a heating wire (not shown) powered by the power supply system of the motor vehicle 1, and the other is a heating tube 51 that uses the vehicle steam generator to provide heat. The heating wire or heating tube 51 can not only heat the sweet sorghum juice in the storage box 42 in real time and effectively perform the sterilization task, but also maintain the juice within a suitable temperature range, resolutely preventing the deterioration problem caused by the long operation cycle, thereby ensuring that the sweet sorghum juice will not deteriorate due to the long operation time during the operation of the sweet sorghum collection, squeezing, throwing and storage machine. The heating wire is directly connected to the power supply device of the motor vehicle 1, and the heating tube 51 is seamlessly connected to the steam generator of the vehicle, making full use of the vehicle's own energy supply, without the need for additional energy equipment, greatly simplifying the overall structure, and improving the system's integration and operating efficiency.

[0057] Furthermore, the squeezing level of the juice extracting device 3 can be one level or multiple levels. As an example, Figure 2As shown, the juice extraction device 3 includes a primary pressing mechanism 31, a secondary pressing mechanism 32 and a diffusion conveying device 33. The primary pressing mechanism 31 is used to perform a primary pressing on the harvested sweet sorghum. The secondary pressing mechanism 32 is used to perform a secondary pressing on the sweet sorghum after the primary pressing. The diffusion conveying device 33 is arranged between the primary pressing mechanism 31 and the secondary pressing mechanism 32, and is used to diffusely convey the sweet sorghum after the primary pressing into the secondary pressing mechanism 32. The primary pressing mechanism 31 performs the first pressing on the sweet sorghum, which mainly presses the whole sweet sorghum. The sweet sorghum pressed by the primary pressing mechanism 31 is then conveyed to the secondary pressing mechanism 32 via the diffusion conveying device 33, and the secondary pressing mechanism 32 presses the sweet sorghum pressed by the primary pressing mechanism 31. The sweet sorghum can be squeezed out of the sweet sorghum juice to a great extent by the double squeezing of the primary squeezing mechanism 31 and the secondary squeezing mechanism 32, thereby improving the juice extraction rate of the sweet sorghum. In addition, the diffusion conveying device 33 can not only convey the sweet sorghum from the primary squeezing mechanism 31 to the secondary squeezing mechanism 32, but also force the sweet sorghum to be diffused along the width direction of the diffusion conveying device 33 during the conveying process, so that the sweet sorghum discharged from the outlet of the primary squeezing mechanism 31 can gradually adapt to the inlet of the secondary squeezing mechanism 32 during the conveying process, and ensure that the secondary squeezing mechanism 32 can receive more sweet sorghum after the primary squeezing and squeeze it more fully.

[0058] Figure 4 FIG. 2 shows a schematic structural diagram of the first-stage pressing mechanism 31 provided in this embodiment. Figure 4 Combined with Figure 1 and Figure 2As shown, both the primary pressing mechanism 31 and the secondary pressing mechanism 32 include a first frame 311, a first hollow pressing roller 312 rotatably and slidably arranged in the first frame 311, a second hollow pressing roller 313 rotatably arranged in the first frame 311, and an elastic pressure component 314 arranged on the first frame 311 and connected to the first hollow pressing roller 312. When the first hollow pressing roller 312 and the second hollow pressing roller 313 rotate in opposite directions, the sweet sorghum entering between the first hollow pressing roller 312 and the second hollow pressing roller 313 can be conveyed in a predetermined direction (i.e., the length direction of the diffusion conveying device 33 or its conveying direction), and pressed by mutual extrusion. The elastic pressure component 314 controls the distance between the first hollow pressing roller 312 and the second hollow pressing roller 313 by its own elastic force, so as to adjust the pressing force of the first hollow pressing roller 312 and the second hollow pressing roller 313 on the sweet sorghum. Through the reverse rotation mechanism of the first hollow pressing roller 312 and the second hollow pressing roller 313, effective directional transportation of sweet sorghum is achieved. In this process, the first hollow pressing roller 312 and the second hollow pressing roller 313 cooperate to squeeze and apply a pressing force to the sweet sorghum, so as to efficiently extract the sweet sorghum juice. And the elastic pressure component 314 can adjust the distance between the first hollow pressing roller 312 and the second hollow pressing roller 313 to meet the squeezing needs at different stages. Specifically, when the sweet sorghum initially contacts and attempts to enter between the first hollow pressing roller 312 and the second hollow pressing roller 313, the elastic pressure component 314 temporarily does not apply an elastic force to the first hollow pressing roller 312, so that the first hollow pressing roller 312 can be easily lifted by the sweet sorghum, and sufficient space is reserved for the smooth entry of the sweet sorghum, which greatly reduces the difficulty of the sweet sorghum entering the squeezing area and ensures the smooth progress of the squeezing process. Once the sweet sorghum completely enters between the first hollow pressing roller 312 and the second hollow pressing roller 313, the elastic pressure component 314 immediately plays its role, and by applying a moderate elastic force, pushes the first hollow pressing roller 312 to approach and squeeze the second hollow pressing roller 313, thereby achieving precise squeezing of the sweet sorghum. This method of dynamically adjusting the squeezing force not only improves the squeezing efficiency, but also ensures the uniform distribution of the squeezing force, avoiding juice loss or sweet sorghum damage caused by uneven squeezing. In addition, due to the hollow setting of the first hollow pressing roller 312 and the second hollow pressing roller 313, the deadweight of the pressing rollers is significantly reduced, making the entire first-level pressing mechanism 31 and the second-level pressing mechanism 32 lighter and easier to integrate into the sweet sorghum collection, squeezing, throwing and storage machine. The squeezing force of the first hollow pressing roller 312 and the second hollow pressing roller 313 is adjusted by the elastic force of the elastic pressure component 314, so that the first hollow pressing roller 312 and the second hollow pressing roller 313 can still efficiently squeeze the sweet sorghum while being lighter. This perfect combination of lightweight and efficient squeezing allows the first-level squeezing mechanism 31 and the second-level squeezing mechanism 32 to maintain a high juice yield and processing efficiency while greatly reducing the difficulty of moving and deploying the sweet sorghum collection, squeezing, throwing and storage machine.

[0059] Further, the first frame 311 includes a base 3111, a first support arm 3112 and a second support arm 3113 both fixedly disposed on the base 3111 and parallel to each other, a first bearing seat 3114 and a second bearing seat fixedly disposed on the first support arm 3112 and the second support arm 3113 in sequence and respectively connected to the rotating shafts at both ends of the second hollow pressing roller 313, and a third bearing seat 3115 and a fourth bearing seat slidably disposed on the first support arm 3112 and the second support arm 3113 in sequence and respectively connected to the rotating shafts at both ends of the first hollow pressing roller 312. The third bearing seat 3115 is located above the first bearing seat 3114, and the fourth bearing seat is located above the second bearing seat. By fixing the first bearing seat 3114 and the second bearing seat on the first support arm 3112 and the second support arm 3113 in sequence, and connecting the rotating shafts at both ends of the second hollow pressure roller 313 respectively, the second hollow pressure roller 313 can be rotated while being restricted by the first support arm 3112 and the second support arm 3113. By slidably arranging the third bearing seat 3115 and the fourth bearing seat on the first support arm 3112 and the second support arm 3113 in sequence, the first hollow pressure roller 312 can be moved closer to or away from the second hollow pressure roller 313, so that the elastic pressure component 314 can adjust the spacing between the first hollow pressure roller 312 and the second hollow pressure roller 313.

[0060] It should be noted that, in the present embodiment, the primary pressing mechanism 31 and the secondary pressing mechanism 32 are almost identical mechanical structures, the main difference between them being the different sizes. To save space, in the present embodiment, only the structural schematic diagram of the primary pressing mechanism 31 is shown and the specific structure of the primary pressing mechanism is described in detail.

[0061] The elastic pressure component 314 may be any elastic device for applying pressure, such as an elastic device with a spring or a gas spring as the core. As a preferred example, the elastic pressure component 314 includes a first hydraulic cylinder 3141 and a second hydraulic cylinder 3142 and one or two pressure accumulators 3143 that are simultaneously or sequentially connected to the rodless chambers of the first hydraulic cylinder 3141 and the second hydraulic cylinder 3142. The cylinder body of the first hydraulic cylinder 3141 is fixed on the first support arm 3112, and its rod body is fixed on the first bearing seat 3114, and the cylinder body of the second hydraulic cylinder 3142 is fixed on the second support arm 3113, and its rod body is fixed on the second bearing seat. The pressure accumulator 3143 can store energy and gradually grow as the rods of the first hydraulic cylinder 3141 and the second hydraulic cylinder 3142 contract, ensuring that the first hydraulic cylinder 3141 and the second hydraulic cylinder 3142 can simultaneously control the first hollow pressing roller 312 from both sides of the first hollow pressing roller 312 after the sweet sorghum enters between the first hollow pressing roller 312 and the second hollow pressing roller 313, so as to ensure that the first hollow pressing roller 312 is as close to the second hollow pressing roller 313 as possible and the sweet sorghum is stably pressed. The center axis of the first hydraulic cylinder 3141 and the center axis of the second hydraulic cylinder 3142 are arranged to pass through the center axis of the first hollow pressing roller 312 and the second hollow pressing roller 313, so as to ensure that the diameter of the first hollow pressing roller 312 remains coplanar with the diameter of the second hollow pressing roller 313 regardless of whether it is moving or stationary, thereby ensuring effective pressing of the sweet sorghum.

[0062] Preferably, the plane where the central axis of the first hollow press roller 312 and the central axis of the second hollow press roller 313 are located is the selected plane, and the angle between the selected plane and the predetermined direction is an acute angle, and the acute angle is located on the feed side of the pressing mechanism where it is located, which helps to guide the flow direction of the sweet sorghum when it enters the first hollow press roller 312 and the second hollow press roller 313, so that the sweet sorghum can enter more smoothly, thereby improving the efficiency and uniformity of feeding.

[0063] Figure 5 FIG. 2 shows a front view of the first-stage pressing mechanism 31 provided in this embodiment. Figure 5 Combined with Figure 1-Figure 4As shown, the first hollow roller 312 and the second hollow roller 313 each include a roller body 3121 and a plurality of ridges 3122 arranged on the roller body 3121 along the circumferential direction and spaced apart along the axial direction. Each ridge 3122 of the first hollow roller 312 and each ridge 3122 of the second hollow roller 313 are staggered in the axial direction of either one of the two. When the first hollow roller 312 and the second hollow roller 313 rotate, the ridges 3122 can effectively squeeze the sweet sorghum and make the juice flow out from the gap between two adjacent ridges 3122. The staggered arrangement of the ridges 3122 helps to guide the flow of the sweet sorghum between the first hollow roller 312 and the second hollow roller 313, reducing the accumulation and adhesion of the sweet sorghum between the first hollow roller 312 and the second hollow roller 313, so that the sweet sorghum can be transported and processed more efficiently.

[0064] Furthermore, the first hollow pressing roller 312 and the second hollow pressing roller 313 both include a wavy groove 3123 which is arranged on the pressing roller body 3121 and cuts off each convex ridge 3122. The wavy groove 3123 can drive the sweet sorghum between the first hollow pressing roller 312 and the second hollow pressing roller 313 to move from the feed side to the discharge side to avoid accumulation of the sweet sorghum, and the wavy groove can drive all the sweet sorghum between the first hollow pressing roller 312 and the second hollow pressing roller 313 in stages (that is, when the first hollow pressing roller 312 and the second hollow pressing roller 313 rotate at a certain angle, part of the wavy groove 3123 drives the sweet sorghum), thereby reducing the load on the first hollow pressing roller 312 and the second hollow pressing roller 313.

[0065] Further, the first hollow roller 312 includes a juice inlet hole 3124 provided on its convex ridge 3122 and connected to the inside of the roller body 3121, and a juice discharge hole 3125 provided on the end surface of the roller body 3121. Thus, the cooperation of the juice inlet hole 3124 and the juice discharge hole 3125 can achieve a part of the juice first entering the first hollow roller 312 and then flowing out of the first hollow roller 312, thereby achieving the flow control of the juice. The second hollow roller 313 includes a juice inlet hole provided on its convex ridge and connected to the inside of the roller body, and a juice discharge hole provided on the end surface of the roller body. Thus, the cooperation of the juice inlet hole and the juice discharge hole can achieve a part of the juice first entering the second hollow roller 313 and then flowing out of the second hollow roller 313, thereby achieving the flow control of the juice.

[0066] It should be noted that, in the present embodiment, the first hollow pressure roller 312 and the second hollow pressure roller 313 are of almost identical mechanical structures, the main difference between them being their sizes. To save space, in the present embodiment, only the structural schematic diagram of the first hollow pressure roller 312 is shown, and the specific structure of the primary pressing mechanism is described in detail.

[0067] Figure 6FIG. 4 shows a cross-sectional view of the first-stage pressing mechanism 31 provided in this embodiment. Figure 6 Combined with Figure 1-Figure 5 As shown, the primary pressing mechanism 31 and the secondary pressing mechanism 32 also include a first combing plate 315 arranged on the frame and used to remove adhesions on the first hollow pressing roller 312, and a second combing plate 317 arranged on the frame and used to remove adhesions on the second hollow pressing roller 313, so as to remove adhesions (sweet sorghum after being pressed) on the first hollow pressing roller 312 and the second hollow pressing roller 313 to prevent the adhesions from accumulating and affecting the normal operation of the first hollow pressing roller 312 and the second hollow pressing roller 313.

[0068] Furthermore, the primary pressing mechanism 31 and the secondary pressing mechanism 32 further include a first support plate 316, see Figure 6 The first support plate 316 is disposed on the frame and is used to guide the sweet sorghum to smoothly enter between the first hollow pressing roller 312 and the second hollow pressing roller 313 to achieve efficient introduction of the sweet sorghum.

[0069] Furthermore, the primary pressing mechanism 31 and the secondary pressing mechanism 32 further include an in-roller 318 and an out-roller 319. The in-roller 318 is rotatably mounted on the frame and can in-roll the sweet sorghum between the first hollow pressing roller 312 and the second hollow pressing roller 313 when rotating, so as to provide another part of power when the sweet sorghum is introduced between the first hollow pressing roller 312 and the second hollow pressing roller 313. The out-roller 319 is rotatably mounted on the frame and can assist the first hollow pressing roller 312 and the second hollow pressing roller 313 in outputting the sweet sorghum when rotating, so as to provide another part of power when the sweet sorghum is output from between the first hollow pressing roller 312 and the second hollow pressing roller 313. The input roller 318 and the output roller 319 can prevent the sweet sorghum from being blocked due to insufficient power when being imported and exported, which helps to maintain the efficient operation of the primary pressing mechanism 31 and the secondary pressing mechanism 32 and reduce the probability of downtime of the primary pressing mechanism 31 and the secondary pressing mechanism 32.

[0070] Continue to refer to Figure 1 and Figure 2 As shown, the sweet sorghum collecting, squeezing, throwing and storing machine also includes a gathering and conveying device 6 arranged on the motor vehicle 1. The gathering and conveying device 6 is arranged between the juicing device 3 and the crushing and throwing device 7, and is used to convey the squeezed sweet sorghum to the crushing and throwing device 7, so that the crushing and throwing device 7 can crush and throw the sweet sorghum.

[0071] Figure 7 The structure diagram of the diffusion transport device 33 provided in this embodiment is shown. Figure 8 FIG. 4 shows a top view of the gathering and conveying device 6 provided in this embodiment, Fig. 9 FIG. 3 shows a schematic structural diagram of the cloth roller 3331 provided in this embodiment. Figure 7-Figure 9 Combined with Figure 1-Figure 6 As shown, both the diffusion conveying device 33 and the gathering conveying device 6 include a second frame 331, a first conveyor 332 and a cloth roller group 333. The first conveyor 332 is arranged in the second frame 331. The cloth roller group 333 includes at least two cloth rollers 3331 arranged above the first conveyor 332 and spaced along the length direction of the first conveyor 332, each cloth roller 3331 includes a roller body 33311 rotatably arranged in the second frame 331, and a first spiral blade 33312 and a second spiral blade 33313 wound on the outer circumference of the roller body 33311, wherein the first spiral blade 33312 and the second spiral blade 33313 are mirror-symmetrical about a selected cross section of the roller body 33311, and the selected cross section refers to a cross section perpendicular to the central axis of the roller body 33311 and passing through the midpoint of the width direction of the roller body 33311. The distribution roller group 333 and the first conveyor 332 convey the sweet sorghum along the length of the first conveyor 332 in a clamping manner, wherein each distribution roller 3331 in the distribution roller group 333 causes the conveyed sweet sorghum to spread or gather in the width direction of the first conveyor 332 through its respective first spiral blade 33312 and second spiral blade 33313. On the one hand, the first spiral blade 33312 and the second spiral blade 33313 can squeeze the sweet sorghum relative to the smooth distribution roller 3331, so as to ensure that the sweet sorghum can be stably conveyed along the length direction of the first conveyor 332 under the joint clamping of the first conveyor 332 and the distribution roller group 333. On the other hand, the opposite spiral directions of the first spiral blade 33312 and the second spiral blade 33313 can cause the sweet sorghum to spread or gather in the width direction of the first conveyor 332 while being conveyed along the length of the first conveyor 332. The synergistic effect of the first conveyor 332 and the cloth roller group 333 realizes the precise clamping and conveying of the sweet sorghum. The diffusion conveying device 33 and the gathering conveying device 6 effectively solve the problem that the traditional conveying device cannot be adjusted in the width direction, so that it can better match the primary pressing mechanism 31, the secondary pressing mechanism 32 and the crushing and throwing device 7. During the pressing process, the diffusion conveying device 33 can adapt the sweet sorghum output by the primary pressing mechanism 31 to the receiving range of the secondary pressing mechanism 32 and convey it to the secondary pressing mechanism 32, thereby improving the working efficiency of the secondary pressing mechanism 32. During the throwing process, the gathering conveying device 6 can adapt the sweet sorghum squeezed by the secondary pressing mechanism 32 to the receiving range of the crushing and throwing device 7 and convey it to the crushing and throwing device 7, reducing the waste of sweet sorghum and improving the efficiency and accuracy of the overall operation.

[0072] Specifically, the diffusion conveying device 33 and the gathering conveying device 6 are almost similar mechanical structures, and the main difference is that the input end and the output end of the sweet sorghum collection, pressing, throwing and storage machine are placed in different directions. Figure 7 Combined with Figure 1-Figure 8 As shown, viewed from the input end to the output end of the first conveyor 332, the structure of the first spiral blade 33312 and the second spiral blade 33313 at the intersection thereof is an inverted herringbone shape, and the rolling of the roller body 33311 enables the sweet sorghum to be spread in the width direction of the gathering and conveying device 6. Fig. 9 FIG. 4 shows a top view of the diffusion transport device 33 provided in this embodiment, as shown in FIG. Fig. 9 Combined with Figure 1-Figure 8 As shown, the structure of the first spiral blade 33312 and the second spiral blade 33313 at the intersection of the first conveyor 332 from the input end to the output end is in a herringbone shape, and the rolling of the roller body 33311 is used to gather the sweet sorghum in the width direction of the diffusion conveying device 33.

[0073] Among them, the first spiral blade 33312 and the second spiral blade 33313 are mirror-symmetric about the selected section of the roller body 33311, and the selected section refers to the section perpendicular to the central axis of the roller body 33311 and passing through the midpoint of the width direction of the roller body 33311, so that the sweet sorghum transported along the length direction of the first conveyor 332 is evenly spread or gathered.

[0074] Furthermore, the second frame 331 includes a symmetrically arranged first guard plate 3311 and a second guard plate 3312, the chain conveyor is installed between the first guard plate 3311 and the second guard plate 3312, and the cloth roller group 333 is also installed between the first guard plate 3311 and the second guard plate 3312. The symmetrically arranged first guard plate 3311 and the second guard plate 3312 can effectively prevent the material from being offset or scattered during the conveying process.

[0075] Furthermore, the thickness of the first guard plate 3311 and the thickness of the second guard plate 3312 gradually increase along the length direction of the first conveyor 332 to cooperate with the cloth roller group 333 so that the sweet sorghum transported along the length direction of the first conveyor 332 can be effectively gathered.

[0076] Continue to refer to Figure 7 Combined with Figure 1-Figure 6As shown, the diffusion conveying device 33 and the gathering conveying device 6 also include a transmission mechanism 334 arranged in the second frame 331 and connected to a plurality of cloth rollers 3331, and the transmission mechanism 334 is used to transmit the power generated by the power device of the motor vehicle 1 to each cloth roller 3331, and make the linear speed of each cloth roller 3331 decrease or increase along the conveying direction of the first conveyor 332, so that the speed of the sweet sorghum conveyed along the length direction of the first conveyor 332 gradually decreases or increases, so as to cooperate with the diffusion or gathering effect of the first spiral blade 33312 and the second spiral blade 33313, so as to more smoothly adapt to the processing requirements of the pressing or throwing process in the subsequent process.

[0077] Specifically, the number of the cloth rollers 3331 is N, where N is a positive integer greater than or equal to 2, and the transmission mechanism 334 includes an i-th belt transmission assembly arranged between the i-th cloth roller 3331 and the i+1-th cloth roller 3331, and the i-th cloth roller 3331 is adjacent to the i+1-th cloth roller 3331 and is closer to the input side of the first conveyor 332 than the i+1-th cloth roller 3331, and the i-th belt transmission assembly includes an i-th driving pulley 3341 arranged on the i-th cloth roller 3331, an i-th driving pulley 3342 arranged on the i+1-th cloth roller The i-th driven pulley 3342 on 3331, and the i-th synchronous belt 3343 sleeved on the i-th driving pulley 3341 and the i-th driven pulley 3342, wherein the number of teeth of the i-th driving pulley 3341 is less than or greater than the number of teeth of the i-th driven pulley 3342, wherein i∈[1, N-1], through the cooperation of the driving pulley 3341, the driven pulley 3342 and the synchronous belt 3343, the linear speed of each cloth roller 3331 can be arranged along the length direction of the first conveyor 332 and gradually decrease or increase.

[0078] Exemplarily, when the number of cloth rollers 3331 is 2, the transmission mechanism 334 includes a first belt transmission assembly arranged between the first cloth roller 3331 and the 1+1 cloth roller 3331, and the first cloth roller 3331 is adjacent to the second cloth roller 3331 and is closer to the input side of the first conveyor 332 than the second cloth roller 3331, and the first belt transmission assembly includes a first driving pulley 3341 arranged on the first cloth roller 3331, a first driven pulley 3342 arranged on the second cloth roller 3331, and a first synchronous belt 3343 mounted on the first driving pulley 3341 and the first driven pulley 3342, wherein the number of teeth of the first driving pulley 3341 is less than or greater than the number of teeth of the first driven pulley 3342.

[0079] Furthermore, the second frame 331 includes a first slide groove 3313 for rotatably accommodating the first end of the cloth roller 3331, and a second slide groove 3314 for rotatably accommodating the second end of the cloth roller 3331. The first slide groove 3313 and the second slide groove 3314 are bar-shaped holes. The first slide groove 3313 and the second slide groove 3314 can provide movement space for the cloth roller 3331, so that the distance between the cloth roller 3331 and the first conveyor 332 can change according to the thickness of the sweet sorghum therebetween, so that the diffusion conveying device 33 or the gathering conveying device 6 can be better adapted to the conveying of sweet sorghum.

[0080] The first conveyor 332 is preferably a chain plate conveyor, which includes a frame, a chain plate 3321 provided in the frame and used to support the first conveyor 332, and a plurality of supporting rollers supporting the chain plate 3321, wherein the plurality of supporting rollers are arranged at intervals along the length direction of the first conveyor 332. The chain plate 3321 can prevent the sweet sorghum from falling during the conveyance along the length direction of the first conveyor 332, and the supporting rollers can provide effective support for the chain plate 3321, so as to prevent the chain plate 3321 from collapsing during the conveyance of a large amount of sweet sorghum by the first conveyor 332.

[0081] Fig.10 The schematic diagram of the structure of the crushing and throwing device 7 provided in this embodiment is shown as follows: Fig.10 Combined with Figure 1-Figure 9 As shown, the crushing and throwing device 7 includes a conveying pipe 71, a crusher 72 and an exhaust fan 73. The conveying pipe 71 is provided on the motor vehicle 1, and is used to receive the squeezed sweet sorghum. The crusher 72 is provided in the conveying pipe 71 and crushes the sweet sorghum passing through it. The exhaust fan 73 is provided on the conveying pipe 71 and can discharge the crushed sweet sorghum out of the conveying pipe 71, so as to crush the sweet sorghum and discharge the crushed sweet sorghum.

[0082] like Figure 2 Combined with Figure 1-Figure 10 As shown, the integrated sweet sorghum harvesting, squeezing, throwing and storing machine further includes a feeding device 8 disposed on the motor vehicle 1 and located between the harvesting device 2 and the juice extracting device 3. The feeding device 8 includes a second conveyor and a feeding roller group disposed above the second conveyor. The feeding roller group and the second conveyor convey the sweet sorghum along the length direction of the second conveyor in a clamping manner. Exemplarily, the feeding roller of the feeding roller group may be a cloth roller 3331 without spiral blades, and the second conveyor may be a chain plate conveyor.
