Description

Technical Field

[0001] The utility model relates to the technical field of reed bamboo harvesting, in particular to a harvester straightening device used for reed bamboo harvesting. Background Art

[0002] The emergence of harvesters has greatly improved the harvesting efficiency of crops and reduced the labor intensity of harvesting crops. However, the harvesting equipment on the market is mainly for the harvesting of field crops such as rice, corn, wheat, etc. and cash crops such as cotton and peanuts. Among them, the harvesters for field crops have been relatively mature after decades of technical improvements and are suitable for the harvesting requirements of rice, wheat or corn. The harvesting equipment for cash crops such as cotton and peanuts has begun to develop rapidly in recent years. However, due to the large differences in the growth habits of different crops, for specific crops, it is difficult for general harvesting equipment to perfectly solve the harvesting problems of different crops. Polyploid reed bamboo encounters such a problem when harvesting. Due to the growth habits of polyploid reed bamboo, the structure and function settings of ordinary harvesting equipment are not applicable, and the effect of application in production is not ideal. The harvesting equipment of polyploid reed bamboo is modified by using existing harvesting equipment, and suitable structural units are added to the existing harvesting equipment to meet the harvesting requirements of polyploid reed bamboo.

[0003] At present, in the existing polyploid Phragmites australis harvesting equipment, although the long auger devices installed on both sides of the front end can automatically straighten the fallen Phragmites australis, in actual operation, the straightening effect is not satisfactory. The long auger devices often cannot effectively straighten the Phragmites australis completely during the straightening process, and the straightened Phragmites australis is prone to fall down again, which not only affects the harvesting efficiency, but also may cause waste and damage to the Phragmites australis. In view of this, a harvester straightening device for Phragmites australis harvesting is designed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a harvester straightening device for harvesting reed bamboo, which solves the problem that the prior art often cannot effectively and completely straighten the reed bamboo during the straightening process, and the reed bamboo after straightening is easy to fall down again, which not only affects the harvesting efficiency but also may cause waste and damage to the reed bamboo.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a harvester straightening device for reed harvesting, comprising a header, a front end of which is fixedly connected to a plurality of rice-supporting assemblies, and the transmission directions of adjacent rice-supporting assemblies are opposite;

[0006] The crop supporting assembly includes a gear box, a crop divider is fixedly connected to the front end of the gear box, a sprocket is rotatably connected to the front end of the crop divider, the sprocket is connected to the output end of the gear box through a chain transmission, and a plurality of toggle members are fixedly connected to the outer side of the chain at equal intervals.

[0007] Preferably, the longitudinal section of the crop divider is triangular, and the outer diameter of the crop divider gradually decreases along the side away from the gear box.

[0008] Preferably, the cross-section of the gear box is elliptical, and the maximum outer diameter of the crop divider is equal to the outer diameter of the gear box.

[0009] Preferably, a receiving groove is provided in the middle of the crop divider and the gear box, and the chain is located inside the receiving groove.

[0010] Preferably, support rods are fixedly connected to both sides of the top of the cutting platform, and a straightening rod is fixedly connected to the top between the two support rods.

[0011] Preferably, the angle between the support rod and the cutting platform is 20-40°.

[0012] Preferably, the distance between the righting rod and the bottom of the header is 1.5-2.2 m, and the length of the righting rod is 2-3 m.

[0013] Preferably, both ends of the straightening rod are arranged inwardly in an arc shape.

[0014] Preferably, a rotating shaft is rotatably connected inside the cutting table, and spiral teeth are fixedly connected to both sides of the outer surface of the rotating shaft, and the spiral directions of the two spiral teeth are opposite.

[0015] Preferably, the bottom of the front end of the cutting platform is transmission-connected with a cutter, the outer side of the cutting platform is fixedly connected with a transmission mechanism, the transmission mechanism is transmission-connected with multiple gear boxes, rotating shafts and cutters respectively, and a feeding port is provided in the middle of the cutting platform.

[0016] By means of the above technical solution, the utility model provides a harvester straightening device for reed harvesting, which has at least the following beneficial effects:

[0017] 1. Replace the long auger devices on both sides of the existing harvesting table with chain-transported straw-supporting components. Compared with the original long auger devices, the straightening effect is significantly improved, and it can achieve the straightening of ultra-high-stalk crops including polyploid Phragmites australis. The fallen Phragmites australis can be straightened by the straw-supporting components located at the front end of the harvester and transported to the harvesting table. Not only is the straightening effect better, but it can also better adapt to Phragmites australis with different lodging conditions and height changes.

[0018] 2. The gearbox transmits power to the sprocket through the chain, driving the chain and the toggle on it to move together. The straw divider separates the reeds, avoiding entanglement and collision between the reeds during the straightening process. When the harvester moves forward, the reeds enter between two adjacent straw dividers. As the sprocket rotates, the chain and the toggle on it straighten the reeds toward the cutting platform, which can adapt to reeds in different lodging conditions and has a good straightening effect.

[0019] 3. A straightening rod is installed at the front end of the harvesting platform to enhance the gathering and straightening effect of the reeds in front of the harvester, effectively preventing the reeds from falling towards the cockpit after being cut during the harvesting process.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-7 A harvester straightening device for harvesting reed bamboo comprises a header 1, a front end of which is fixedly connected with a plurality of straw supporting assemblies 2, wherein the transmission directions of adjacent straw supporting assemblies 2 are opposite; the length of the straw supporting assembly 2 is 2m, and when working, the straw supporting assembly 2 moves inward at a rotation speed of 120 to 200 rpm, thereby ensuring that the reed bamboo can be straightened continuously when the harvester moves forward.

[0031] The straw-supporting assembly 2 includes a gearbox 201, a straw divider 202 is fixedly connected to the front end of the gearbox 201, a sprocket 203 is rotatably connected to the front end of the straw divider 202, the sprocket 203 is connected to the output end of the gearbox 201 through a chain 204, and a plurality of toggle members 205 are fixedly connected to the outer side of the chain 204 at equal intervals. The gearbox 201 transmits power to the sprocket 203 through the chain 204, driving the toggle members 205 on the chain 204 to move together, and the straw divider 202 separates the reed bamboo, avoiding entanglement and collision between the reed bamboo during the straightening process. When the harvester moves forward, the reed bamboo enters between two adjacent straw dividers 202. As the sprocket 203 rotates, the chain 204 and the toggle members 205 thereon straighten the reed bamboo toward the direction of the cutting platform 1, which can adapt to reed bamboo with different lodging conditions, and has a good straightening effect.

[0032] The longitudinal section of the crop divider 202 is triangular, and the outer diameter of the crop divider 202 gradually decreases along the side away from the gear box 201. This arrangement makes the front end of the crop divider 202 sharper, making it easier to cut into the reed bushes and separate the reeds during the harvesting process, which can effectively reduce the resistance encountered by the harvester during the forward movement and make the crop separation process smoother.

[0033] The cross-section of the gear box 201 is elliptical, and the maximum outer diameter of the straw divider 202 is equal to the outer diameter of the gear box 201, so that the two form a whole, so that the straw supporting assembly 2 has better stability during operation, reduces safety accidents caused by shaking or vibration, and improves operation safety.

[0034] The middle parts of the crop divider 202 and the gear box 201 are both provided with a receiving groove, and the chain 204 is located inside the receiving groove, which provides a protective space for the chain 204 and enhances stability.

[0035] Support rods 4 are fixedly connected to both sides of the top of the header 1, and a straightening rod 5 is fixedly connected to the top between the two support rods 4. The straightening rod 5 is installed at the front end of the header 1 to enhance the gathering and straightening effect of the reeds in front of the harvester, and effectively avoid the situation where the reeds are cut off and fall towards the cockpit during the harvesting process.

[0036] The angle between the support rod 4 and the cutting platform 1 is 20-40°. The distance between the straightening rod 5 and the bottom of the cutting platform 1 is 1.5-2.2m, and the length of the straightening rod 5 is 2-3m. The two ends of the straightening rod 5 are arranged inwardly in an arc shape. Such a setting can ensure that the straightening rod 5 can effectively straighten the reed and gather it into the cutting platform 1, improve the harvesting efficiency, and prevent the reed from falling into the cockpit after being cut during the harvesting process, which not only protects the operator in the cockpit, but also reduces the loss during the harvesting process.

[0037] The inside of the cutting table 1 is rotatably connected to a rotating shaft, and spiral teeth 6 are fixedly connected to both sides of the outer surface of the rotating shaft, and the spiral directions of the two spiral teeth 6 are opposite. The bottom of the front end of the cutting table 1 is transmission-connected to a cutter 8, and the outer side of the cutting table 1 is fixedly connected to a transmission mechanism 3, which is transmission-connected to multiple gear boxes 201, the rotating shaft and the cutter 8 respectively, and a feeding port 7 is provided in the middle of the cutting table 1. The transmission mechanism 3 can drive multiple gear boxes 201, the rotating shaft and the cutter 8 to operate, and when the multiple gear boxes 201 are in operation, efficient straightening of the reed can be achieved, and the operation of the cutter 8 can cut off the straightened reed, and the operation of the rotating shaft can drive the two spiral teeth 6 to rotate. Since the spiral directions of the two spiral teeth 6 are opposite, the cut reed can be gathered to the middle and transported to the feeding port 7 to enter the harvester.

[0038] Working principle: When in use, the transmission mechanism 3 can drive multiple gear boxes 201, rotating shafts and cutters 8 to operate;

[0039] The gear box 201 transmits power to the sprocket 203 through the chain 204, driving the chain 204 and the toggle member 205 thereon to move together, and the straw divider 202 separates the reeds, avoiding entanglement and collision between the reeds during the straightening process. When the harvester moves forward, the reeds enter between two adjacent straw dividers 202. As the sprocket 203 rotates, the chain 204 and the toggle member 205 thereon straighten the reeds toward the cutting platform 1;

[0040] The operation of the cutter 8 can cut the straightened reed, and the operation of the rotating shaft can drive the two spiral teeth 6 to rotate. Since the spiral directions of the two spiral teeth 6 are opposite, the cut reed can be gathered to the middle and transported to the feeding port 7 to enter the harvester.
