Abstract
Description
Technical Field
[0001] The utility model relates to a component of a sugarcane surface leaf stripping device, in particular to a sugarcane surface leaf stripping cutter and a cutter combination, belonging to the technical field of sugarcane harvesting machinery. Background Art
[0002] When sugarcane is harvested, it has many stems and leaves on the surface. If the leaves are not processed and used for sugar extraction, the leaves will adhere to the sugar juice and be wasted, which will significantly reduce the sugar yield. Therefore, the leaves on the surface of the sugarcane must be removed as much as possible before sugar extraction. The traditional method of stripping the leaves on the surface of sugarcane mainly adopts manual stripping, that is, the harvested sugarcane is stripped manually with the help of a stripping knife. The labor intensity is high and the efficiency is low, so it has been gradually replaced by mechanical stripping.
[0003] In order to obtain higher defoliation efficiency and better defoliation quality, the inventor has specially designed a new type of sugarcane surface defoliation equipment according to the characteristics of sugarcane to perform mechanized defoliation on the harvested sugarcane. In this equipment, the sugarcane is moved by a conveying mechanism, and then the surface defoliation of the moving sugarcane is performed by using a specially set sugarcane defoliation cutter and a cutter combination. The sugarcane surface defoliation cutter and the cutter combination of the utility model are the main components of the sugarcane surface defoliation equipment for scraping off the surface leaves of the sugarcane. Utility Model Content
[0004] The utility model aims to provide a sugarcane surface leaf stripping cutter and a cutter combination, which can scrape off the leaves on the surface of the sugarcane by scraping the side edges.
[0005] The technical solution adopted by the utility model is as follows:
[0006] A sugarcane surface leaf stripping tool is provided with a horizontally arranged base plate, on which a row of longitudinal vertical blade plates are fixedly connected and arranged at equal intervals in the left-right direction, the vertical blade plate is a right-angled triangle plate with the hypotenuse facing forward when viewed from left to right, the left and right edges of the hypotenuse on the front side of the vertical blade plate serve as scraping edges of the vertical blade plate, and the channel between the two vertical blade plates is the leaf stripping channel; a horizontal blade plate is fixedly connected to the lower back of each vertical blade plate close to the base plate, the horizontal blade plate is a circular plate with the center on the longitudinal center plane of the vertical blade plate when viewed from top to bottom, and the horizontal blade plate is embedded in the vertical blade plate from back to front to a certain depth, and the upper edge of the arc edge on the front side of the horizontal blade plate serves as the scraping edge of the horizontal blade plate; each horizontal blade plate is at the same height, and a gap is left between two adjacent horizontal blade plates.
[0007] A tool assembly based on the above-mentioned sugarcane surface leaf stripping tool, which is provided with multiple leaf stripping tools arranged in a row from front to back, the odd-numbered leaf stripping tools are placed in a forward direction with the base plate at the bottom and the scraping edge at the front, and the even-numbered leaf stripping tools are placed in an inverted direction with the base plate at the top and the scraping edge at the front, and the horizontal blade plate on the odd-numbered leaf stripping tools is lower than the horizontal blade plate on the even-numbered leaf stripping tools by a certain height. Furthermore, the vertical blade plates on the odd-numbered leaf stripping tools and the vertical blade plates on the even-numbered leaf stripping tools are staggered by a certain distance on the longitudinal plane.
[0008] The sugarcane surface leaf stripping cutter of the utility model has a simple structure and is easy to use. It adopts a side edge scraping method and utilizes the left and right side edges of the front oblique edge of the vertical knife plate and the upper side edge of the front arc edge of the horizontal knife plate as scraping edges. When the sugarcane passes through the leaf stripping channel between two vertical knife plates, the scraping edges can scrape off the leaves on the surface of the sugarcane. Moreover, since the side edges are relatively rough and blunt as the cutting edges, the leaves on the surface of the sugarcane can be scraped off without easily scratching the sugarcane core rod. Therefore, the sugarcane core rod can be relatively completely retained to enter the next process, thereby avoiding the loss of sugar due to damage to the sugarcane core rod. Since the diameters of sugarcane stems vary and they have certain curvatures, the width of the leaf stripping channel for the sugarcane to pass through must be greater than the diameter of the sugarcane, and the sugarcane often twists when passing through the leaf stripping channel. In order to ensure that the sugarcane can be stripped in all directions, a tool combination constructed by the leaf stripping tool can be used. In this way, when stripping leaves, no matter the sugarcane stems have different diameters or are twisted and deflected, they can be fully stripped without missing leaves.

[0020] The utility model is further described below in conjunction with the accompanying drawings. In the description of the utility model, the directional words "up", "down", "left" and "right" are based on the attached drawings of the specification. Figure 1 and Fig.10 The orientation or position relationship indicated is defined only for the convenience of describing the present invention, rather than referring to a specific orientation that a device or element must have, and should not be regarded as a limitation to the present invention.
[0021] like Figure 1-4 As shown, the sugarcane surface leaf stripping tool of the utility model is provided with a horizontally arranged base plate 1, on which a row of longitudinal upright blade plates 2 are arranged at equal intervals in the left-right direction are fixedly connected, the upright blade plate 2 is a right-angled triangle plate with the hypotenuse facing forward when viewed from left to right, the left and right edges of the hypotenuse on the front side of the upright blade plate 2 serve as scraping edges of the upright blade plate 2, and the channel between the two upright blade plates 2 is the leaf stripping channel; a horizontal blade plate 3 is fixedly connected to the lower back of each upright blade plate 2 close to the base plate 1, the horizontal blade plate 3 is a circular plate with the center on the longitudinal center plane of the upright blade plate 2 when viewed from top to bottom, and the horizontal blade plate 3 is embedded in the upright blade plate 2 from back to front by a certain depth, and the upper edge of the arc edge on the front side of the horizontal blade plate 3 serves as the scraping edge of the horizontal blade plate 3; each horizontal blade plate 3 is at the same height, and a gap is left between two adjacent horizontal blade plates 3.
[0022] Furthermore, the vertical blade plate 2 of the right-angled triangle plate can be replaced by a vertical blade plate 2 of a quasi-right-angled triangle plate, and the hypotenuse of the vertical blade plate 2 of the quasi-right-angled triangle plate is constructed by a curve of a shape other than a straight line, such as Figure 5 and Figure 6 shown.
[0023] Furthermore, the vertical blade plate 2 of the right-angled triangle plate can also be replaced by the vertical blade plate 2 of the right-angled trapezoidal plate, and the hypotenuse of the vertical blade plate 2 of the right-angled trapezoidal plate faces forward, such as Figure 7Similarly, the vertical blade plate 2 of the right-angled trapezoidal plate can also be replaced by the vertical blade plate 2 of the quasi-right-angled trapezoidal plate, and the hypotenuse of the vertical blade plate 2 of the quasi-right-angled trapezoidal plate is constructed by other shape curves besides straight lines, such as Figure 8 and Fig. 9 shown.
[0024] When the leaf stripping tool is in use, the conveying mechanism drives multiple sugarcanes to move from front to back, so that each sugarcane passes through the leaf stripping channel between the two vertical blade plates 2 respectively, and at the same time, the sugarcane is pressed against the top surfaces of the two adjacent horizontal blade plates 3 in the leaf stripping channel. While the sugarcane passes through the leaf stripping channel, the scraping edges of the vertical blade plates 2 and the horizontal blade plates 3 can scrape off the leaves on the surface of the sugarcane, and the scraped leaves can be brought out backwards and fall naturally through the gaps between the horizontal blade plates 3 and the base plate 1, the gaps between the two horizontal blade plates 3, and the gaps in the leaf stripping channel.
[0025] Since the diameters of sugarcane stems vary and have certain curvatures, the width of the leaf stripping channel for the sugarcane to pass through must be greater than the diameter of the sugarcane, and the sugarcane often twists when passing through the leaf stripping channel. If only one leaf stripping tool is provided to strip the leaves, leaves will often be missed in the top and part of the side directions of the sugarcane. In order to ensure that the sugarcane can be stripped in all directions, a tool combination constructed by the leaf stripping tool can be used to solve this problem, thereby obtaining the following solution.
[0026] like Figure 10-12 As shown, the tool assembly based on the above-mentioned sugarcane surface peeling tool of the utility model is provided with multiple stripping tools arranged in a row from front to back, the odd-numbered stripping tools are placed in a forward direction with the base plate 1 at the bottom and the scraping edge at the front, and the even-numbered stripping tools are placed in an inverted direction with the base plate 1 at the top and the scraping edge at the front, and the horizontal blade 3 on the odd-numbered stripping tools is lower than the horizontal blade 3 on the even-numbered stripping tools by a certain height. Furthermore, the vertical blade 2 on the odd-numbered stripping tools and the vertical blade 2 on the even-numbered stripping tools are staggered by a certain distance on the longitudinal plane.
[0027] When this tool combination is used, the sugarcane is sequentially passed through the leaf stripping channel between the two vertical blade plates 2 of each leaf stripping tool, and the sugarcane is placed against the top surfaces of the two adjacent horizontal blade plates 3 in the leaf stripping channel, and the vertical blade plates 2 and horizontal blade plates 3 on the odd-numbered leaf stripping tools are used to strip the lower half of the sugarcane surface, and the vertical blade plates 2 and horizontal blade plates 3 on the even-numbered leaf stripping tools are used to strip the upper half of the sugarcane surface. At the same time, since the vertical blade plates 2 on the odd-numbered leaf stripping tools and the vertical blade plates 2 on the even-numbered leaf stripping tools are staggered by a distance on the longitudinal plane, when the sugarcane moves from front to back, it meanders in a slightly reciprocating swing on the longitudinal plane. At this time, no matter how the sugarcane is twisted and deflected during the leaf stripping process, it can be fully stripped without missing leaves.
[0028] The above-mentioned figures are only typical embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
