Description

Technical Field

[0001] The invention relates to the field of rice straw processing equipment, and in particular to a complete set of equipment for harvesting, crushing and collecting rice straw. Background Art

[0002] Straw is a general term for the stems and leaves of mature crops, usually referring to the remaining parts of coarse grains such as wheat, rice, corn, potatoes, rapeseed, and cotton after the seeds are harvested. In the past, straw was usually burned, but considering the environmental damage, public health, and safety hazards caused by straw burning, straw burning has been completely banned. In the southern region, rice can be planted for multiple seasons, and a large amount of rice straw will be produced in each season. There are difficulties in harvesting and processing rice straw, which has high labor costs and low efficiency.

[0003] like Figure 1 As shown, it is a harvesting and crushing device for corn straw processing in the north (refer to patent 201820245729.9). The shell includes a knife roller and a conveying roller. The crushing part and the output part are installed on the outside of the shell near the conveying roller. The front end of the shell is used to connect the traction equipment, and the rear end of the shell is installed with a pressing roller. After the grain is ripe, the harvester harvests the grain. After harvesting, the straw has been cut and lies flat on the ground, but there will still be 30-40cm of straw stubble left in the soil. Figure 1 The knife roller in the device has a freely rotatable blade (visible Figure 2 ), the flap has a certain bending structure, which is used to break the straw stubble for cutting, and at the same time, the straw lying on the ground can be pulled into the equipment. The conveying roller is used to concentrate the machine of the income equipment to the crushing part, the crushing part crushes the straw and outputs it through the output part, and the rear pressure roller is used to level the field on the one hand, and on the other hand, it can also be used as a support point (the other side is supported by the traction equipment), and cooperate with the traction equipment to realize the walking of the harvesting and crushing equipment in the field.

[0004] However, the above equipment is only suitable for dry and hard corn fields, and is not suitable for southern rice fields for the following reasons: Figure 2 As shown, Figure 1 The actual picture of the blade on the middle knife roller. The blade is actually a thin plate without blades. If the thin plate needs to cut the straw stubble, the rotation speed must be fast and the whole machine must be heavy enough, especially the roller body part ( Figure 1 Although the knife roller in the equipment has adopted a hollow roller structure, which reduces a considerable part of the weight, in order to ensure the cutting force and roller strength, the roller wall is still very thick and heavy) to obtain sufficient cutting force while ensuring the stability of the whole machine. This causes the harvesting and crushing equipment to sink in rice fields with high water content and become unable to move.

[0005] Based on this, this case is brought forward. Summary of the invention

[0006] The purpose of the present invention is to provide a complete set of equipment for harvesting, crushing and collecting rice field straw, which ensures the cutting effect and greatly reduces the weight of the equipment through structural optimization so that it can be used in rice fields.

[0007] To achieve the above object, the technical solution of the present invention is as follows:

[0008] A complete set of equipment for harvesting, crushing and collecting rice field straw, comprising a casing, wherein a knife roller and a conveying roller are arranged in the casing, a pressure roller is installed at the rear end of the casing, a plurality of cutting knife groups are arranged on the outer wall of the roller body of the knife roller, the cutting knife group comprises a mounting seat, a mounting shaft and a beating blade, the mounting seat is fixed on the outer wall of the roller body of the knife roller, and the beating blade is rotatably connected to the mounting seat through the mounting shaft; the beating blade is used for cutting the part of the straw stubble, the roller body of the knife roller is hollow, and the hollow part is filled with a lightweight filling material with adhesive properties.

[0009] Furthermore, the filler is made of polyurethane.

[0010] Furthermore, the roller bodies of the knife roller and / or the conveying roller and / or the pressure roller are made of seamless steel pipes.

[0011] Furthermore, each of the cutting knife groups includes two cutting blades, each of which includes an integrally formed connecting portion and a cutting portion, wherein the connecting portion is used to connect to the mounting seat, and the edge of the cutting portion is sharpened for cutting off straw stubble; the connecting portion and the cutting portion give the cutting blade a bent shape.

[0012] Furthermore, the cutting portion and the connecting portion make the blade L-shaped, and the two blades on the same mounting seat are T-shaped.

[0013] Furthermore, the mounting seat includes two vertical plates, the centers of the vertical plates are provided with mounting holes for connecting the mounting shafts, the vertical plates are provided with integrally formed reinforcing plates, and the reinforcing plates are fixed to the outer wall of the roller body of the knife roller.

[0014] Furthermore, ribs are provided on the plate surface of the casing.

[0015] Furthermore, the casing is made of alloy material.

[0016] Furthermore, the roller body of the pressing roller is hollow, and the hollow part is filled with a lightweight filler having adhesive properties.

[0017] Furthermore, the conveying roller comprises spiral conveying blades arranged at both ends of the roller body in opposite directions and a plurality of material-discharging blades arranged in the middle of the roller body. The roller body of the conveying roller is hollow, and the hollow part is filled with a lightweight filler with adhesive properties.

[0018] Furthermore, the material-moving blade includes plate one and plate two, one end of plate one is fixed to the roller body of the conveying roller, and the other end is fixed to one end of plate two, the connection between plate one and plate two is bent, and the angle between plate one and plate two is an obtuse angle.

[0019] Furthermore, a reinforcing plate is provided between the material-shifting blade and the roller body of the conveying roller.

[0020] Furthermore, the middle part of the roller body of the conveying roller is divided into several sections along its axial direction, and each section is arranged with a plurality of material-shifting blades, and the material-shifting blades on two adjacent sections are arranged in a staggered manner.

[0021] The advantages of the present invention are:

[0022] 1. The edge of the blade is sharpened to make it a real blade. While ensuring that the straw can be cut, the cutting force can be reduced, thereby reducing the wall thickness of the blade roller, conveyor roller, and pressure roller, and reducing the thickness of the casing, etc., so that the weight of the whole machine is greatly reduced, so that the equipment can be moved on the rice field;

[0023] 2. Each roller body is made of seamless steel pipe, and the hollow part is filled with lightweight and adhesive fillers, such as polyurethane. The filled viscous fillers are lightweight and have high hardness, which can support the roller body and disperse stress. This can further reduce the wall thickness of each roller body, so as to ensure strength and rigidity and reduce the weight of the whole machine. At the same time, when the wall thickness of the roller body is reduced, the diameter of the roller can be increased, so as to increase the support force of the paddy field on the equipment while reducing the weight.

[0024] 3. The casing is made of alloy material, which is light and strong compared to iron plate. It can reduce the wall thickness and weight while ensuring strength. In addition, the present application fills the plate body of the casing with ribs, which can improve the strength of the casing. On this basis, the thickness of the plate body can be further reduced, further reducing the weight of the entire machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The present invention is further described in detail below in conjunction with the embodiments. It should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" herein are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention.

[0040] This embodiment provides a set of equipment for harvesting, crushing and collecting rice straw. Figures 3 to 5As shown, the machine comprises a housing 1, an input port 102 is provided at the front side of the housing 1, an output port 103 is provided at the rear side, a knife roller 2 is provided at the front side of the housing 1, a conveying roller 4 is provided at the rear side of the housing 1, a crushing box, a conveying belt, etc. can be installed at the output port 103, and the arrangement of the crushing box and the conveying belt can refer to the attached Figure 1 A traction device connection part 8 is provided on the top of the housing 1, and the traction device connection part 8 is used to connect with the traction device, and at the same time input the power of the traction device and transmit it to the knife roller 2, the conveying roller 4, the crushing box, etc. A pressing roller 3 is installed on the rear side of the outer shell 1 through a bracket. The rice straw is cut by the knife roller 2 and pulled into the housing, and is output to the crushing part by the conveying roller 4 for crushing. The output part outputs the crushed straw powder, and the pressing roller 3 plays the role of supporting the equipment and leveling the field.

[0041] like Figure 6 and Figure 7 As shown, the roller body of the knife roller 2 is a hollow roller made of seamless steel pipe, and a plurality of cutting knife groups are arranged on the outer wall of the roller body of the knife roller 2. The cutting knife groups include a mounting seat 201, a mounting shaft 202 and a beating piece 203. The mounting seat 201 is fixed on the outer wall of the roller body of the knife roller 2, and the beating piece 203 is rotatably connected to the mounting seat 201 through the mounting shaft 202. Each of the cutting knife groups includes two blades 203, and the blades 203 include an integrally formed connecting portion 2031 and a cutting portion 2032, wherein the connecting portion 2031 is connected to the mounting seat 201 through the mounting shaft 202, and the edge of the cutting portion 2032 is sharpened for cutting straw stubble; the connecting portion 2031 and the cutting portion 2032 make the blades 203 bent. In this embodiment, the cutting portion 2032 and the connecting portion 2031 make the blades 203 L-shaped (that is, the blades are vertically bent at 90°), and the two blades on the same mounting seat 201 are T-shaped. Since the blades 203 can rotate freely, when the knife roller 2 rotates, the blades 203 spread radially along the knife roller 2 under the action of inertia. The 90° bending shape of the blades can effectively cut the rice straw stubble, and at the same time, pull the straw lying flat in the field into the casing 1. Compared with other bending angles, the 90° bending has greater force and range in pulling materials.

[0042] The edge of the blade 203 is sharpened to make the blade 203 a real blade. While ensuring that the straw can be cut, the cutting force can be reduced, thereby reducing the wall thickness of the roller body of the cutter roller 2 and the plate thickness of the housing 1, so that the weight of the whole machine is greatly reduced. It should be noted here that reducing the cutting force is the key to reducing the weight of the whole machine. If the cutting force is not reduced, the weight of the whole machine will be reduced, which will lead to unstable operation of the equipment and insufficient cutting force. In order to ensure the strength and rigidity of the roller body of the cutter roller 2, the hollow part of the roller body of the cutter roller 2 is filled with a lightweight and adhesive filler 7, such as polyurethane (depending on the formula, the filled polyurethane can show various hardness characteristics from soft to extremely hard to meet the needs of different application scenarios, such as soft pads, elastic components, to hard plastic components, etc.). The filler 7 supports the roller body of the cutter roller 2. Combined with the rigidity of the seamless steel pipe, the thickness of the roller body of the cutter roller 2 can be further reduced, the weight can be reduced, and the strength and rigidity of the roller body can be ensured at the same time.

[0043] Preferably, the mounting seat 201 of this embodiment includes two vertical plates 2011, and a mounting hole for connecting the mounting shaft 202 is provided at the center of the vertical plate 2011. An integrally formed reinforcing plate 2012 is provided on the vertical plate 2011. The reinforcing plate 2012 is fixed to the outer wall of the roller body of the knife roller 2. The reinforcing plate 2012 can increase the rigidity of the mounting seat 201 to prevent it from being deformed when the knife roller 2 is operating.

[0044] like Figure 8 and Fig. 9As shown, the conveying roller 4 includes spiral conveying blades 401 arranged at both ends of the roller body and in opposite directions and a plurality of material-dispensing blades 402 arranged in the middle of the roller body. The output port 103 of the housing 1 is opposite to the material-dispensing blades 402. The straw that is pulled into the housing 1 is transported to the material-dispensing blades 402 by the spiral conveying blades 401 on both sides, and is simultaneously dispensed out of the housing 1 by the material-dispensing blades 402 to enter the subsequent crushing and output process. In this embodiment, in order to reduce the weight of the conveying roller 4, the conveying roller 4 is configured as a hollow roller body, and the hollow part is filled with a lightweight and adhesive filler 7, such as polyurethane. Under the condition of ensuring strength and stiffness, the wall thickness of the hollow roller body can be further reduced to reduce weight. In addition, the roller body of the conveying roller 4 can be made of seamless steel pipe to improve strength and stiffness, avoid stress concentration, and further reduce wall thickness. The material-digging blade 402 of this embodiment includes a plate 1 4021 and a plate 2 4022. One end of the plate 1 4021 is fixed to the roller body of the conveying roller 4, and the other end is fixed to one end of the plate 2 4022. The connection between the plate 1 4021 and the plate 2 4022 is bent, and the angle between the plate 1 4021 and the plate 2 4022 is an obtuse angle. The setting of the obtuse angle can ensure the strength and effectiveness of the material digging. At the same time, in order to ensure the continuity of the material digging, the middle part of the roller body of the conveying roller 4 is divided into several sections along its axial direction, and each section is evenly distributed with 3 material-digging blades 402 (that is, the 3 material-digging blades are arranged circumferentially at an interval of 120°), and the material-digging blades 402 on two adjacent sections are staggered. In order to ensure the rigidity of the material-digging blade 402, a reinforcing plate 4023 is provided between the material-digging blade 402 and the roller body of the conveying roller 4 in this embodiment to prevent it from deforming during high-speed operation.

[0045] like Fig.10 and Fig.11 As shown, in order to reduce the weight of the pressure roller 3, the pressure roller 3 is set as a hollow roller in this embodiment, and the hollow part of the roller body is filled with a lightweight and adhesive filler 7, such as polyurethane. Under the condition of ensuring strength and rigidity, the wall thickness of the hollow roller body can be further reduced to reduce the weight. In addition, the roller body of the pressure roller 3 can be made of seamless steel pipe to improve strength and rigidity, avoid stress concentration, and further reduce the wall thickness. When the wall thickness of the roller body of the pressure roller 3 is reduced, the diameter of the pressure roller 3 can be increased, and the support force of the paddy field on the equipment can be increased while reducing the weight.

[0046] like Fig.12 As shown, in order to further reduce the plate thickness of the casing 1, the casing 1 of this embodiment is made of alloy steel or a material with rigidity greater than alloy steel. At the same time, ribs 101 are provided on the plate surface of the casing 1 to ensure its strength and rigidity, which can greatly reduce the wall thickness and reduce the weight of the whole machine.

[0047] The above embodiments are only used to explain the concept of the present invention, rather than to limit the protection of the rights of the present invention. Any non-substantial changes to the present invention using this concept shall fall within the protection scope of the present invention.
