Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and specifically relates to a convenient sugarcane bud removal machine. Background Technology

[0002] When planting sugarcane, tender stalks cut or removed from the sugarcane are usually selected. These stalks have strong growth ability and vitality, making them easy to survive and grow. Currently, the cutting of sugarcane buds is usually done manually or by machine. Manual operation is labor-intensive, inefficient, and unsuitable for modern agricultural production. Furthermore, traditional manual operations often involve random cutting, resulting in stalk pieces of varying sizes, low germination rates, and significant waste, increasing planting costs. While existing machine-based bud removal reduces labor intensity and ensures the size of the cut stalks, its function is relatively limited and inconvenient to operate. Moreover, current sugarcane bud cutting devices can only cut sugarcane into sections, but in reality, sugarcane seedling cultivation only requires the bud and a small portion of the surrounding sugarcane. This results in the waste of sugarcane that could be used for sugar production, causing economic losses.

[0003] Chinese patent application (CN118024323A) discloses a sugarcane bud cutting device. Compared with traditional sugarcane stalk cutting equipment, this device improves the blade by replacing the traditional straight blade with a curved blade and setting sap outlet holes on the blade surface. This significantly reduces sugarcane waste during the sugarcane bud cutting process and improves economic efficiency. However, sugarcane buds are not distributed on the same side of the sugarcane stalk nodes. This means that when cutting with a machine, it is necessary to rotate the sugarcane simultaneously so that the stalk and bud are facing the direction to be cut to remove the stalk and bud, which increases the cumbersomeness of the operation.

[0004] Therefore, considering the above technical issues, there is an urgent need to design a sugarcane bud-removing machine that can cut sugarcane buds according to their growth direction. Utility Model Content

[0005] The purpose of this invention is to provide a convenient sugarcane bud removal machine, overcoming the limitations of traditional sugarcane bud cutting devices that can only cut buds facing the same direction. This invention provides a bud removal machine with hyperboloid blades that can be driven to cut buds on sugarcane according to their growth direction. The specific technical solution is as follows:

[0032] Example

[0033] like Figures 1 to 4 As shown, a portable sugarcane bud removal machine includes a mounting bracket 100, on which a carrying platform 110 is provided, and a discharge port 111 is provided on the carrying platform 110. A bud removal mechanism 200 is installed on the carrying platform 110. When performing bud removal (seed cutting) operation, sugarcane is placed into the bud removal mechanism 200, and the bud removal mechanism 200 cuts or removes the buds located at the sugarcane nodes. The removed buds are discharged from the discharge port 111. It is worth mentioning that, in order to facilitate the unified collection and processing of the removed buds, a seed stalk receiving basket 120 is placed below the carrying platform 110. The seed stalk receiving basket 120 is located directly below the discharge port 111, which can collect the cut seed stalks uniformly.

[0034] Preferably, the bud-removing mechanism 200 includes a conveying part 210, a positioning part 220, a fixing part 230, and a bud-removing part 240. The conveying part 210 is mounted on the support platform 110 and has an inlet end and an outlet end. The positioning part 220 is located on the left and right sides of the outlet 111. The fixing part 230 is mounted on the support platform 110 and located on one side of the positioning part 220. The bud-removing part 240 is mounted on the support platform 110, and the output end of the bud-removing part 240 faces the outlet 111.

[0035] In some preferred embodiments, the conveying unit 210 includes a first conveying mounting frame 211, fixed conveying rollers 212, a second mounting frame 213, a first spring 214, a roller mounting frame 215, an elastic conveying roller 216, and a mounting beam 217. The first conveying mounting frame 211 is mounted on the mounting bracket 100, and a plurality of the fixed conveying rollers 212 are rotatably mounted on the first conveying mounting frame 211. The second mounting frame 213 is mounted on the mounting bracket 100 and located on opposite sides of the fixed conveying rollers 212. The mounting beam 217 is mounted on two mounting brackets 213. The mounting beam 217 is provided with mounting holes. The roller mounting bracket 215 is slidably disposed on the mounting holes. The spring 214 is sleeved on the roller mounting bracket 215. The elastic conveying roller 216 is mounted on the roller mounting bracket 215. The degree of pressure on the sugarcane can be adjusted by the spring 214. The adjustment of the spring 214 makes the conveying part 210 suitable for conveying sugarcane of different diameters.

[0036] In some preferred embodiments, the fixed conveying roller 212 and the elastic conveying roller 216 are in an hourglass shape, with a conveying opening between them for sugarcane to pass through. The structure of the fixed conveying roller 212 and the elastic conveying roller 216 can limit the sugarcane during the conveying process (preventing the sugarcane from slipping out of the conveying section 210), and can also be finely adjusted according to the diameter of the sugarcane during the conveying process to adapt to the conveying operation of sugarcane with different diameters, thereby improving the applicability of the device.

[0037] In some preferred embodiments, the positioning part 220 includes a mounting plate 221, a second spring 222, an elastic guide block 223, a fixed guide block 224, and an elastic contact strip 225. The elastic guide block 223 and the fixed guide block 224 are mounted opposite each other on the bearing platform 110 and are located at the discharge end. The elastic guide block 223 is slidably mounted on the mounting plate 221 by the second spring 222. The mounting plate 221 is mounted on the bearing platform 110. The elastic contact strip 225 is disposed at the discharge port 111 and points into the discharge port 111.

[0038] Similarly, the positioning part 220 can be finely adjusted according to the diameter of the sugarcane during the conveying process by the spring 222, so as to adapt to the conveying operation of sugarcane with different diameters and improve the applicability of the device. The elastic contact strip 225 can be made of rubber. The purpose is to determine whether the sugarcane stalk has reached the designated cutting position through the elastic contact strip 225, so as to facilitate the subsequent precise seed removal operation of the bud removal part 240. It is worth mentioning that the conveying port formed by the elastic guide block 223 and the fixed guide block 224 is chamfered, which is to facilitate the conveying of sugarcane. At the same time, the elastic guide block 223 can be used to clamp the sugarcane radially. When conveying sugarcane, the sugarcane needs to be placed flat on the carrying platform 110, and the growth direction of the stalk should be opposite to that of the input end. The stalk should be placed as flat as possible on the carrying platform 110.

[0039] In some preferred embodiments, the fixing part 230 includes a fixed mounting support 231, a telescopic cylinder 232, and a pressure plate 233. The fixed mounting support 231 is installed on the bearing platform 110 and located on the left and right sides of the discharge port 111. The telescopic cylinder 232 is installed on the fixed mounting support 231. The pressure plate 233 is located on the output end of the telescopic cylinder 232. The pressure plate 233 is used to press down the sugarcane body to ensure the stability of the sugarcane when removing the seed.

[0040] In some preferred embodiments, the bud-removing section 240 includes a bud-removing mounting bracket 241, a first driving cylinder 242, a second driving cylinder 243, a first cutting blade 244, and a second cutting blade 245. The bud-removing mounting bracket 241 is mounted on the support platform 110. The first driving cylinder 242 and the second driving cylinder 243 are mounted on the bud-removing mounting bracket 241. The first cutting blade 244 is mounted on the output end of the first driving cylinder 242, and the second cutting blade 245 is mounted on the output end of the second driving cylinder 243. The cutting blade is driven by the driving cylinder to perform the cutting operation on the sugarcane node.

[0041] Furthermore, the first cutting blade 244 and the second cutting blade 245 have the same structure. Both the first cutting blade 244 and the second cutting blade 245 are arc-shaped blades. The concave surface of the first cutting blade 244 faces opposite to the concave surface of the second cutting blade 245. The first driving cylinder 242 and the second driving cylinder 243 are arranged adjacent to each other to selectively drive the cylinders, thereby cutting off the buds located at the sugarcane nodes. (Since the sugarcane buds are not all distributed on the same side of the sugarcane stem node, this structure can better cut off the stalks located on different sides, eliminating the need for manual flipping in conjunction with the cutting blades.) This reduces tedious work steps and improves operational efficiency. The shape of the cutting blades is just right to remove the buds and a small portion of the sugarcane around them, reducing waste. After removing the buds, the remaining sugarcane can still be sent for sugar production, improving the utilization rate of raw materials.

[0042] In summary, this utility model provides a convenient sugarcane bud removal machine. This machine can selectively remove buds from both sides without requiring manual turning of the sugarcane to cooperate with the cutting blade, reducing tedious work steps and improving operational efficiency. The conveying and positioning parts of the bud removal machine provided by this utility model can be adjusted according to the diameter of the sugarcane to be conveyed, improving the applicability of the device and ensuring smooth sugarcane conveying. The positioning part of this utility model includes an elastic contact strip, which can touch the seed stalk on the sugarcane node to determine that the seed stalk has reached the corresponding cutting position, facilitating precise bud removal operations in the subsequent bud removal section.
