Description

Technical Field

[0001] This utility model applies to the field of agricultural machinery and equipment technology, and provides an automatic sugarcane harvester that collects and dumps sugarcane. Background Technology

[0002] Sugarcane, a popular fruit and an important raw material for sugar production, is widely cultivated in southern my country. However, due to the complex terrain in many southern regions, large agricultural machinery is unsuitable for sugarcane harvesting. Therefore, most sugarcane fields in these areas still rely on manual harvesting, which is inefficient and costly. Currently, some solutions involve using machines to directly push down the sugarcane before collection. However, this direct-push method results in uneven breakage and irregular cuts, easily leading to crop loss. Furthermore, unlike rice, sugarcane has a much larger unit weight and size, making the transportation of harvested sugarcane a significant challenge. Utility Model Content

[0003] Therefore, this utility model provides an automatic sugarcane harvester that collects and dumps sugarcane. By mounting it on a small tractor to complete the sugarcane harvesting, the sugarcane roots are cut using a cutting device, and then transferred and dumped into the sugarcane collection bin by a clamping and conveying device. After the sugarcane collection bin is fully loaded with harvested sugarcane, it can be transferred to a designated location and dumped by a position transfer drive mechanism and a dumping drive mechanism, ensuring that the sugarcane can be better stored and transferred at the same time as it is harvested.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic sugarcane harvester for collecting fallen sugarcane, comprising:

[0005] A rack, used to mount various devices;

[0006] The clamping and conveying device includes a first circulating chain and a second circulating chain spaced apart on a frame. Both the first circulating chain and the second circulating chain are provided with a plurality of outwardly protruding soft clamping parts. A first guide rod is fixedly provided above the first circulating chain, and a second guide rod is fixedly provided above the second circulating chain.

[0007] A cutting device includes at least one cutting disc and a disc drive mechanism. The cutting disc is disposed below a first circulating chain and a second circulating chain. The disc drive mechanism is connected to the cutting disc drive mechanism to drive the cutting disc to rotate.

[0008] A collection and dumping device includes a fixed connecting frame fixedly connected to a machine frame, a position transfer frame rotatably connected to the fixed connecting frame, a position transfer drive mechanism disposed between the fixed connecting frame and the position transfer frame, the position transfer drive mechanism being used to drive the position transfer frame to rotate, a sugarcane collection bin rotatably connected to the position transfer frame, and a dumping drive mechanism disposed between the position transfer frame and the sugarcane collection bin, the dumping drive mechanism being used to rotate the sugarcane collection bin.

[0009] Furthermore, a sugarcane conveying channel is formed between the first and second circulating chains. An "eight"-shaped sugarcane collection inlet is provided at the beginning of the sugarcane conveying channel. The first guide rod and the second guide rod are respectively provided on both sides above the sugarcane conveying channel. The first guide rod extends from above the first circulating chain to above the sugarcane collection bin, and the second guide rod extends from above the second circulating chain to above the sugarcane collection bin.

[0010] Furthermore, the surface of the soft clamping part is provided with several raised rubber friction strips.

[0011] Furthermore, the sugarcane collecting bin includes a collecting bottom plate and a retaining side plate, wherein the collecting bottom plate and the retaining side plate are arranged in an "L" shape.

[0012] Furthermore, the number of cutting discs is preferably two, the two cutting discs are arranged at an interval from left to right, and the two cutting discs are connected by a gear set.

[0013] Furthermore, a stubble height adjustment device is also provided on one side of the frame. The stubble height adjustment device includes a lifting rod and a lifting drive mechanism. The lifting rod is provided with a telescopic lifting part, and the telescopic lifting part is provided with a bottom limit wheel. The lifting drive mechanism is driven to the lifting rod to drive the telescopic lifting part to move and thereby drive the bottom limit wheel to rise and fall.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In the present invention, the sugarcane to be harvested is gathered through the "eight"-shaped sugarcane collection inlet, the sugarcane root is cut by the cutting disc, and then the sugarcane is transferred upward along the sugarcane conveying channel and away from the ground under the clamping of the soft clamping part on the first and second circulation chains, and finally falls into the sugarcane collection bin of the collection and dumping device under the guidance of the first and second guide rods.

[0016] 2. The sugarcane collection and dumping device moves the sugarcane collection bin by rotating and shifting the position transfer frame. When a certain amount of sugarcane is collected, the position transfer frame moves the sugarcane collection bin to one side of the machine frame. Then, the sugarcane collection bin is flipped to dump the sugarcane to the designated position. The sugarcane can be unloaded automatically during the harvesting process without stopping the machine and manually transferring the sugarcane. Attached Figure Description

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] Example, see attached document Figure 1 Appendix Figure 2 The present invention provides an automatic sugarcane harvester for collecting and dumping sugarcane, including a frame 100, a clamping and conveying device 200, a cutting device 300, and a collecting and dumping device 400.

[0033] The frame 100 is used to mount various devices, and also for connecting to traction equipment such as tractors, as shown in the attached diagram. Figure 3 As shown, the clamping and conveying device 200 includes a first circulating chain 210 and a second circulating chain 220 spaced apart on the frame 100. The first circulating chain 210 and the second circulating chain 220 are either driven by a motor-driven sprocket to rotate the chain or driven by a motor-driven pulley to rotate the conveyor belt. Both the first circulating chain 210 and the second circulating chain 220 extend upwards from near the bottom of the frame 100, forming a sugarcane conveying channel. An "8"-shaped sugarcane collection inlet is located at the beginning of the sugarcane conveying channel. Both the first circulating chain 210 and the second circulating chain 220 are provided with several outwardly protruding soft clamping parts 230. Several raised rubber friction strips are provided on the surface of the soft clamping parts 230, which can increase the friction of the soft clamping parts 230. When the first circulation chain 210 and the second circulation chain 220 are running, the soft clamping parts 230 of the first circulation chain 210 and the second circulation chain 220 will clamp the sugarcane from both sides respectively, driving the sugarcane to move obliquely upward along the sugarcane conveying channel. A first guide rod 240 is fixedly installed above the first circulation chain 210, and a second guide rod 250 is fixedly installed above the second circulation chain 220. The first guide rod 240 and the second guide rod 250 are respectively installed on both sides above the sugarcane conveying channel. The first guide rod 240 extends from above the first circulation chain 210 to above the collecting and pouring device 400, and the second guide rod 250 extends from above the second circulation chain 220 to above the collecting and pouring device 400. When the sugarcane moves upward along the sugarcane conveying channel until it leaves the sugarcane conveying channel, it will be poured towards the collecting and pouring device 400 under the guidance of the first guide rod 240 and the second guide rod 250.

[0034] The cutting device 300 includes at least one cutting disc 310 and a disc drive mechanism 320. In this embodiment, as shown in the attached diagram... Figure 4 As shown, the number of cutting discs 310 is preferably two. These two cutting discs 310 are symmetrically spaced below the sugarcane conveying channel between the first circulating chain 210 and the second circulating chain 220. The disc drive mechanism 320 is driven to drive the cutting discs 310 to rotate. In this embodiment, the disc drive mechanism 320 drives the cutting discs 310 by driving a reducer through a tractor drive shaft. In a specific structure, the two cutting discs 310 are first connected by a gear set. Then, the tractor drive shaft drives one of the cutting discs 310 to rotate through the drive shaft and the reducer. This cutting disc 310 drives the other cutting disc 310 to rotate synchronously in the opposite direction through the gear set. When the clamping and conveying device 200 clamps the sugarcane, the cutting device 300 uses the cutting discs 310 to cut off the sugarcane root.

[0035] The collection and dumping device 400 includes a fixed connecting frame 410 that is fixedly connected to the frame 100, as shown in the attached figure. Figure 5 As shown, a fixed connecting frame 410 is rotatably connected to a position transfer frame 420. A position transfer drive mechanism 430 is provided between the fixed connecting frame 410 and the position transfer frame 420. A sugarcane collecting bin 440 is rotatably connected to the position transfer frame 420. A tilting drive mechanism 450 is provided between the position transfer frame 420 and the sugarcane collecting bin 440. The position transfer drive mechanism 430 is used to drive the position transfer frame 420 to rotate, thereby realizing the change of position of the sugarcane collecting bin 440. The tilting drive mechanism 450 is used for sugarcane collection... The sugarcane collection bin 440 rotates, thereby completing the tilting action of the sugarcane collection bin 440. The sugarcane collection bin 440 includes a collection bottom plate and a material-blocking side plate. The collection bottom plate and the material-blocking side plate are arranged in an "L" shape. When tilting, the sugarcane collection bin 440 will rotate to the side without the material-blocking side plate. The position transfer drive mechanism 430 and the tilting drive mechanism 450 can be in the form of a telescopic hydraulic cylinder or a telescopic air cylinder, which can be directly connected to the hydraulic or air pressure pipeline of tractor or other traction equipment. The structure is simpler and the cost is relatively low.

[0036] In a more optimized embodiment, a stubble height adjustment device 500 is also provided on one side of the frame 100, as shown in the attached figure. Figure 6As shown, the stubble height adjustment device 500 includes a lifting rod 510 and a lifting drive mechanism 530. The lifting rod 510 is provided with a telescopic lifting part, and the telescopic lifting part is provided with a bottom limiting wheel 520. The lifting drive mechanism 530 is driven by the lifting rod 510 to drive the telescopic lifting part to move and thereby drive the bottom limiting wheel 520 to rise and fall. In this embodiment, the lifting drive mechanism 530 adopts a motor or hydraulic motor, while the lifting rod 510 adopts a screw mechanism structure. The lifting function of the telescopic lifting part is realized by driving the screw mechanism through the motor or hydraulic motor. In this embodiment, by changing the height position of the bottom limiting wheel 520 relative to the frame 100, the height of the entire frame 100 above the ground can be changed during operation. This also allows control of the cutting position of the cutting disc 310, making sugarcane harvesting more flexible.

[0037] The working principle of this embodiment is as follows:

[0038] In this embodiment, after the sugarcane harvester is installed on a tractor or other traction device, the position of the bottom limiting wheel 520 is first adjusted according to the required sugarcane root cutting height. Then, the first circulating chain 210, the second circulating chain 220, and the cutting device 300 are started to begin sugarcane harvesting. The sugarcane is first gathered from the figure-eight shaped sugarcane collection inlet and then clamped by the soft clamping parts 230 on the first and second circulating chains 210 and 220. At this time, the sugarcane root is cut off by the cutting disc 310 below. Then, under the clamping of the soft clamping parts 230 on the first and second circulating chains 210 and 220, the sugarcane is transferred upwards along the sugarcane conveying channel, leaving the ground until it leaves the upper end of the sugarcane conveying channel. Guided by the first guide rod 240 and the second guide rod 250, it is poured to one side into the sugarcane collection bin 440 of the collection and dumping device 400. During the sugarcane harvesting process, the position of the sugarcane collection bin 440 is as shown in the attached figure. Figure 7 As shown, the sugarcane collecting bin 440 is positioned directly above the first guide rod 240 and the second guide rod 250. Once a certain amount of sugarcane has been collected in the sugarcane collecting bin 440, the position transfer frame 420 will move the sugarcane collecting bin 440 to one side of the frame 100. Then, the sugarcane collecting bin 440 will flip to tilt the sugarcane to a designated position. The position of the sugarcane collecting bin 440 at this time is shown in the attached figure. Figure 8 As shown, after dumping is complete, the sugarcane collection bin 440 will return to its original position as indicated in the attached diagram. Figure 7 Sugarcane harvesting operations continued at the location shown.
