Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, and in particular to an intelligent sugarcane cleaning device. Background Technology

[0002] Currently, mechanized sugarcane harvesting both domestically and internationally mainly utilizes cutting-type sugarcane harvesters. This method involves cutting the sugarcane into multiple small sections and then using a blower to remove sugarcane leaves and other debris. This results in many small fragments being blown away, and the machine's heavy weight easily crushes the sugarcane stalks. Therefore, the main problems are high loss rates, broken ends, and high impurity content. Sugarcane farmers and sugar mills find this harvesting method unacceptable. Thus, a more suitable sugarcane harvesting machine is urgently needed to solve the problems of the existing technology. Summary of the Invention

[0066] The operating steps of this cleaning equipment are as follows: The operator manipulates the pilot handle operating system 3 to control the large hook arm 4 and the large hook arm claw 12 to pick up the sugarcane (cut and piled by a cutter, spreader, or manually) and place it into the middle hook arm claw 13. Then, the operator presses the start switch of the automatic control cabinet 11. The middle hook arm claw 13 begins to move according to the pre-programmed steps, first shaking to align the sugarcane tail, and then closing the claws to clamp the sugarcane. Specifically, the automatic control cabinet 11 issues a command to control the middle hook arm claw 13 to swing 15 degrees to the left and right (when the middle hook claw swings 15 degrees to the left until the second signal sensor on the left detects the second signal sensor plate on the left, the automatic control cabinet 11 receives a signal confirming that the swing action is in place, and issues a command to control the middle hook arm claw 13 to swing 15 degrees to the right until the second signal sensor on the right detects the second signal sensor plate on the right, the automatic control cabinet 11 receives a signal from the second signal sensor on the right to confirm that the swing action is in place), so that the sugarcane tail is aligned. Subsequently, the automatic control cabinet 11 issues commands to control the rotation of the tail-cutting cutter head 16 and to control the swing of the cutter head frame 15 in the horizontal plane. The swing of the cutter head frame 15 drives the tail-cutting cutter head 16 to move to cut off the sugarcane tail. First signal sensors are installed on the frame corresponding to the start and end points of the swing of the cutter head frame 15, respectively. A first signal sensing plate is welded on the cutter head frame 15. Through the first signal sensing plate and the first signal sensors, the automatic control cabinet 11 can sense the translation start and stop of the cutter head frame 15. Three tail-cutting cutter heads 16 are installed on the cutter head frame 15, each with a corresponding hydraulic motor to drive the rotation of each tail-cutting cutter head 16 to cut off the sugarcane tail.

[0067] After the sugarcane top is cut, the automatic control cabinet 11 sends a command to control the hook arm and claw 13 to rotate 90 degrees clockwise. Once the clockwise rotation is complete, the second signal sensor (corresponding to the clockwise and reverse rotation of the hook arm and claw 13) sends a signal to the automatic control cabinet 11. The automatic control cabinet 11 then sends a command to control the hook arm 5 to rotate 180 degrees to the left, achieved by the first hydraulic motor driving the first column to rotate. Two seventh signal sensors are installed on the frame next to the first slewing bearing. A seventh signal sensor plate is welded to the first column above the first slewing bearing. When the hook arm 5 rotates to the left above the sorting mechanism 7, the seventh signal sensor and the seventh signal sensor plate on one side approach and send a signal back to the automatic control cabinet 11, indicating that the left rotation is complete and instructing the claw to open and release the sugarcane. The automatic control cabinet 11 then instructs the sorting mechanism 7 to operate.

[0068] The sorting mechanism 7 consists of a conveyor sprocket 29, a chain 26, a chain plate 25, a scraper 27, a sorting frame 28, and a sprocket-driven hydraulic motor 30. The sprocket-driven hydraulic motor 30 drives the conveyor sprocket 29 to rotate, which in turn drives the chain 26, chain plate 25, and scraper 27 to rotate. When the hook arm 13 opens its claw on the sorting mechanism 7, the sugarcane falls onto the chain plate 25 of the sorting mechanism 7. At this time, the chain plate 25 and scraper 27 driven by the sprocket-driven hydraulic motor 30 can deliver the sugarcane as needed (the height distance between the sorting mechanism 7 and the hook arm 13 is just about 50mm, allowing only one sugarcane to pass through. Thus, under the push of the scraper 27, the sugarcane is neatly lined up and delivered). A ninth signal sensor is installed on the sorting rack 28. A ninth signal sensor plate is welded and fixed on each scraper 27. Whenever the ninth signal sensor plate on a scraper 27 approaches the ninth signal sensor, the automatic control cabinet 11 issues a command to control the small hook arm and claw 14 to grab and send the sugarcane to the conveyor roller 17.

[0069] The motion control process of the small hook arm 6 can refer to the control process of the middle hook arm 5. The small hook arm 6 is controlled to grab and deliver sugarcane back and forth to the conveyor roller 17 in the same way as the control process of the middle hook arm 5. After that, the conveyor roller 17 delivers the sugarcane to the leaf stripping roller 18. After the leaf stripping roller 18 and the sugarcane delivery roller in the leaf stripping box 8 work, they strip the leaves from the sugarcane, remove all the debris, and transport it outside to be neatly stacked.

[0070] The intelligent sugarcane impurity removal device provided by this invention has the following advantages:

[0071] 1. This sugarcane cleaning equipment first cuts off the sugarcane tops, and then peels off the withered old leaves. In this way, the fresh sugarcane tops can be collected and used as feed for cattle, sheep and other animals, enriching the feed sources for the livestock industry.

[0072] 2. This sugarcane impurity removal equipment removes impurities by peeling the leaves off the whole stalk, without any loss of sugarcane juice or fragments, resulting in a very low loss rate of sugarcane throughout the process.

[0073] 3. It is lightweight and the wheel spacing is suitable for sugarcane row spacing, so it does not crush the sugarcane ratoons and has no impact on the germination rate of the following year.

[0074] 4. After processing, the sugarcane is trimmed and the withered and old leaves are removed, so the impurity content is very low, about two percent. Sugar factories and sugarcane farmers generally prefer this harvesting method, which is conducive to increasing the economic income of sugarcane farmers and sugar factories.

[0075] 5. Because the harvester removes leaves and impurities by cutting off the entire stalk, the fuel consumption is about 5 yuan per ton of sugarcane, while the fuel consumption of a cutting harvester is about 30 yuan per ton of sugarcane. This harvesting and impurity removal method greatly saves energy and reduces pollution.

[0076] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
