Description

Technical Field

[0001] This invention belongs to the field of peeling devices, and in particular a dual-speed, bidirectional sugarcane peeling device. Background Technology

[0002] In the existing technology, CN205612245U is a unidirectional feed and rotary cutting method, and CN205612245U discloses a reciprocating feed cutting method for sugarcane peeling. In addition, there is a study on the influence of different angle blade edges on sugarcane peeling in Anhui Agricultural Sciences, Journal of Anhui Agri.Sci.2012,40(35):17291-17293. The cutting resistance of different sections of sugarcane is different. Traditionally, sugarcane is fed from one end to the other end with a cutting angle and cutting speed. So, is it possible to design a device that can cut sugarcane from both ends at the same time and be equipped with different angle blades and use different cutting speeds? This is worth exploring. In a research paper on the principle of three shock wave roller planetary transmission in the journal Mechanical Transmission, a variable speed bearing is introduced, including shock wheel, internal gear ring, transmission ring and ball, which can realize speed change. So, can we improve and apply it to the design of sugarcane peeling device? Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a dual-speed, bidirectional sugarcane peeling device.

[0004] This dual-speed, bidirectional sugarcane peeling device includes a frame, characterized by a variable-speed bearing located above the frame. The variable-speed bearing comprises an internal gear ring, a central ring, a shock wheel, balls, a left end cover, and a right end cover. The central ring is fixedly positioned on the frame by an L-shaped bracket. The internal gear ring has ZK teeth, the shock wheel has ZH teeth, and the balls have ZK-ZH numbers. The balls are installed in the central ring and contact the outer contour of the shock wheel and the inner contour of the internal gear ring. The inner diameters of the left and right end covers are smaller than the maximum diameter from the center point of the shock wheel to its outer circumference, and the outer diameters are larger than the minimum diameter from the center of the internal gear ring to its inner circumference. A first telescopic rod is fixedly connected to the internal gear ring at 180° intervals, and a second telescopic rod is fixedly connected to the shock wheel at 180° intervals. A first cutter disc is fixed to the right end of the first telescopic rod, and the right side of the first cutter disc is connected to the outer edge of the ball bearing. The inner ring of the ball bearing is connected to the first cylinder via a concave rod. The left end of the second telescopic rod is fixed with a second cutter head, and the right side of the second cutter head is welded and fixed to the outer ring of the ball bearing. The inner ring of the ball bearing is connected to the second cylinder via a concave rod. The inner gear ring has teeth machined on its outer side and is driven by meshing with a gear. The gear is driven by the first motor. A support rod is fixed on the right end cover, and a support plate is fixed on the right end of the support rod. The support plate has a square hole, and a set of fixed blocks and a set of movable blocks are set on the wall of the square hole. A set of guide rods is set at the bottom of the square hole, and the movable blocks are inserted into the guide rods. The movable blocks are connected to the bottom of the square hole via springs. The first roller is rotatably mounted on the fixed block, and the second roller is rotatably mounted on the movable block. A second motor is installed below the support plate, and the second motor drives the first roller to rotate via a sprocket and a chain.

[0005] Preferably, the first motor is fixed on the pad.

[0006] Furthermore, the first cutter head has a circular hole at its center, and two sets of horizontal grooves are arranged on the first cutter head next to the circular hole. A sliding rod is installed in the horizontal groove, and a spring and a slider seat are sleeved on the sliding rod. A spiral cutter is installed between the upper and lower slider seats, and a set of spiral cutters are arranged in parallel. The second cutter head has the same structure as the first cutter head.

[0007] Preferably, the internal gear ring has 7 teeth (ZK), the shock wheel has 3 teeth (ZH), and the ball bearings have 4 teeth.

[0008] In operation, the sugarcane is passed through ball bearings, a first cutter head, a support plate, and a second cutter head. The upper section of the sugarcane faces the first cutter head, and the lower section faces the second cutter head. The first and second rollers of the support plate clamp the sugarcane at the middle section. The first motor drives the internal gear ring to rotate, and the internal gear ring drives the shock wheel to rotate through the balls. Based on the research paper on the principle of three-shock-roller planetary transmission, we adopt a fixed center ring, with the internal gear ring as the power input and the shock wheel as the power output, in a transmission ratio of ZH / ZK with increasing speed. The first cylinder drives the first cutter head to move to the left, and the second... The cylinder drives the second cutter head to move to the right, while the first telescopic rod drives the first cutter head to rotate, and the second telescopic rod drives the second cutter head to rotate. The spiral cutters on the first and second cutter heads clamp the sugarcane and rotate around it to perform a scraping action. The sliding rod, the second spring, and the slider seat work together to allow the parallel spiral cutters to adapt to different diameters of sugarcane. After the first and second cylinders have completed their rotation, the second motor drives the first roller to rotate, thereby feeding the sugarcane to the right. The first cutter head cuts off the uncut middle section, and then the lower section of the sugarcane is finely cut.

[0009] The beneficial effects of this invention are: First, it saves time compared to traditional rotary cutting feed for sugarcane because it cuts simultaneously from both ends, then cuts the middle section last, and finally performs a final finishing cut on the lower section of the sugarcane, saving cutting time and resulting in a cleaner cut; Second, it uses a fixed central ring, an internal gear ring as the power input, and a shock wheel as the power output, with a transmission ratio of ZH / ZK. Other configurations are unsuitable for sugarcane cutting because the sugarcane needs to be fed through the center, making the design of the device very complex; if the number of ball bearings is ZK+ZH, the two cutter heads will generate a large torque on the sugarcane during cutting, thus... Sugarcane damage; because the lower section of sugarcane has a larger cutting load and greater resistance, and is also thicker, it is relatively more difficult to cut cleanly. Therefore, we need a high speed for cutting, generally around 2600-3000 r / min. The cutting load of the lower section of sugarcane is relatively smaller, and the resistance is smaller, generally around 1800-2100 r / min. Since it is in the medium-high speed range, the faster the speed, the smaller the cutting force, which can make the tool life longer. Thirdly, the use of energy springs, movable blocks and slider seats allows the whole device to adapt to sugarcane of different diameters. Attached Figure Description
