Description

TECHNICAL FIELD

[0001] The present application relates to a sugarcane seeding device and method, in particular to a double-bud-section sugarcane precision seeding device and method. BACKGROUND

[0002] Sugarcane is the main sugar crop in China, and its planting is mainly concentrated in hilly and mountainous areas in Guangxi, Yunnan, Guangdong and other places. Mechanized seeding can replace manual seeding, greatly reduce labor costs and promote the development of the industry.

[0003] The existing mechanized sugarcane seeding mainly adopts whole stalk seeding, real-time cutting seeding and pre-cutting seeding (single-bud-section and double-bud-section). Sugarcane precision seeding is one of the key technologies for cost reduction and efficiency increase in sugarcane planting. The current sugarcane planter has poor precision seeding effect when seeding, which is difficult to meet the requirements of precision agriculture. SUMMARY

[0004] The purpose of the present application is to overcome the above-mentioned problems, and to provide a double-bud-section sugarcane precision seeding device which can precisely seed sugarcane sections and meet the requirements of precision agriculture.

[0005] Another purpose of the present application is to provide a double-bud-section sugarcane precision seeding method.

[0006] The purpose of the present application is achieved by the following technical solutions:

[0007] A double-bud-section sugarcane precision seeding device, comprising a vibration feeding mechanism, an intermediate conveying mechanism and a seeding mechanism;

[0008] The vibration feeding mechanism comprises a feeding hopper and a vibration machine, the feeding hopper is connected with the vibration machine, and the feeding hopper is provided with a first feeding channel gradually narrowing at the upper part and a second feeding channel at the lower part; the width of the second feeding channel is smaller than the length of the sugarcane section;

[0009] The intermediate conveying mechanism comprises an intermediate conveying belt and a conveying driving mechanism, the intermediate conveying belt is located below the second feeding channel, and the conveying direction of the intermediate conveying belt is parallel to the length direction of the second feeding channel;

[0010] The seed arranging mechanism comprises a seed arranging box and a seed arranging tray, a seed arranging conveying belt and a seed arranging driving mechanism arranged in the seed arranging box; the seed arranging tray is located below the end of the intermediate conveying belt, is obliquely arranged at one side of the seed arranging conveying belt, and the lower end of the seed arranging tray extends to the direction of the seed arranging conveying belt; a plurality of hook plates are arranged on the seed arranging conveying belt along the length direction of the seed arranging conveying belt; the seed arranging driving mechanism comprises at least two seed arranging conveying rollers; the seed arranging conveying belt is arranged between the seed arranging conveying rollers; and the axis of the seed arranging conveying roller is parallel to the conveying direction of the intermediate conveying belt.

[0011] The working principle of the above-mentioned double-bud-section sugarcane precision seeding device is as follows:

[0012] During operation, the sugarcane sections are put into the feeding hopper, at this time, the sugarcane sections are located in the first feeding channel; the feeding hopper is driven to vibrate by the vibration machine, so as to adjust the posture of the sugarcane sections when they move downward; the sugarcane sections are transferred to the second feeding channel through the first feeding channel which gradually narrows; since the width of the second feeding channel is smaller than the length of the sugarcane sections, and the length direction of the second feeding channel is parallel to the conveying direction of the intermediate conveying belt, at this time, the posture of the sugarcane sections has been preliminarily adjusted, and is generally parallel to the conveying direction of the intermediate conveying belt; then, the sugarcane sections fall onto the intermediate conveying belt below, and are conveyed by the intermediate conveying belt to the direction of the seed arranging box; the sugarcane sections enter the seed arranging box through the seed arranging inlet of the seed arranging box by means of a parabolic motion, and fall onto the inclined seed arranging tray, the sugarcane sections are guided by the seed arranging tray to the direction of the seed arranging conveying belt, so that the sugarcane sections roll to the direction of the seed arranging conveying belt, and then the posture of the sugarcane sections is adjusted to a uniform posture, so as to be accurately hooked subsequently; the seed arranging conveying belt is driven by the seed arranging driving mechanism to move, so that the hook plates move from bottom to top, and then the sugarcane sections are sequentially hooked one by one, and then the sugarcane sections are sequentially sowed out through the seed arranging outlet of the seed arranging box.

[0013] In one preferred embodiment of the present application, the first feeding channel is provided with two obliquely arranged lower guide bottom surfaces, and the two lower guide bottom surfaces are located at different heights. In this way, the two lower guide bottom surfaces are located at different heights, which can prevent the sugarcane sections from crossing the outlet of the first feeding channel, and effectively avoid the situation of blocking the channel.

[0014] Further, the second feeding channel is provided with a partition plate, the partition plate divides the second feeding channel into two falling spaces in the width direction; and the width of the falling space is smaller than half the length of the sugarcane section. In this way, when the sugarcane section enters the second feeding channel, the initial position adjustment is completed; when the sugarcane section contacts the partition plate, the sugarcane section is divided into one of the falling spaces by the partition plate, and the posture of the sugarcane section is further constrained, so that the position adjustment is performed again, so as to obtain a relatively uniform posture, so as to be conveyed by the intermediate conveying belt.

[0015] Further, the height of the partition plate is less than the height of the lower guide bottom with smaller height, which can effectively avoid the three-point force of the roller material and block in the channel.

[0016] In one preferred embodiment of the present application, the second delivery channel is provided with an anti-blocking plate at the end close to the seed metering mechanism; and the anti-blocking plate is inclined forward from bottom to top in the conveying direction of the intermediate conveying belt. Through the above structure, the anti-blocking plate will vibrate with the delivery hopper during discharging, which can effectively prevent the sugarcane segments from being blocked at the corner.

[0017] In one preferred embodiment of the present application, the intermediate conveying mechanism comprises a limiting plate arranged on both sides of the intermediate conveying belt.

[0018] In one preferred embodiment of the present application, the seed metering mechanism further comprises a feeding roller and a feeding drive mechanism, the feeding roller is arranged between the lower end of the seed metering plate and the seed metering conveying belt, and the axis of the feeding roller is parallel to the axis of the seed metering conveying roller. Through the above structure, when the sugarcane segment falls on the seed metering plate, it will automatically roll to one side of the seed metering conveying roller; the seed metering conveying roller is driven to rotate by the feeding drive mechanism, and the sugarcane segment is rolled to the hook plate of the seed metering conveying belt on the other side by the seed metering conveying roller; in this process, the sugarcane segment can be sent to the hook plate of the seed metering conveying belt one by one and in place, and more importantly, the rolling seed metering conveying roller adjusts the posture of the sugarcane segment in a dynamic way, finally ensuring that the sugarcane segment is transferred to the hook plate of the seed metering conveying belt in the correct posture, and ensuring normal seed metering work.

[0019] Further, in the direction perpendicular to the surface of the seed metering plate, the height difference between the feeding roller and the surface of the seed metering plate is equal to the radius of the feeding roller. When the sugarcane segment slides off the seed metering plate, due to the height difference, the sugarcane segment collides with the feeding roller, corrects the posture, and then is transmitted in parallel to the hook plate of the seed metering conveying belt.

[0020] Further, the feeding drive mechanism is composed of the seed metering drive mechanism.

[0021] Further, both sides of the seed metering plate are provided with leakage openings, and the arrangement direction of the two leakage openings is parallel to the axis of the feeding roller.

[0022] Both ends of the feeding roller are provided with arc-shaped baffles, and the curvature of the arc-shaped baffles is greater than the curvature of the feeding roller. Through the above structure, the leakage openings can automatically discharge the chaotic sugarcane seeds, and the greater curvature of the arc-shaped baffles can prevent the sugarcane seeds to be fed into the hook plate of the seed metering conveying belt from being affected by the two arc-shaped baffles.

[0023] In one preferred embodiment of the present application, a weighing sensor is arranged below the seed metering plate to real-time the amount of sugarcane seeds in the seed metering box, so as to prevent the seed metering box from being overfilled.

[0024] A double-bud section sugarcane precision seeding method, comprising the following steps:

[0025] Put the sugarcane section into the feeding hopper, at this time the sugarcane section is located in the first feeding channel; drive the feeding hopper to vibrate by the vibration machine, and adjust the posture of the sugarcane section when it moves downward;

[0026] The sugarcane section is transferred to the second feeding channel through the first feeding channel which gradually narrows, at this time the posture of the sugarcane section has been preliminarily adjusted;

[0027] The sugarcane section falls downward to the middle conveying belt below, and the sugarcane section is conveyed to the direction of the seed box by the middle conveying belt;

[0028] The sugarcane section enters the seed box through the seed box entrance by a flat throwing motion, and falls on the inclined seed conveying plate, the sugarcane section is guided to the direction of the seed conveying belt by the seed conveying plate, so that the sugarcane section rolls to the direction of the seed conveying belt, and then the posture of the sugarcane section is adjusted to a uniform posture;

[0029] The seed conveying belt is driven by the seed conveying drum of the seed driving mechanism to move, so that the hook plate moves from bottom to top, and the sugarcane section is hooked one by one in turn, and then the sugarcane section is sequentially sent out through the seed box outlet.

[0030] Compared with the prior art, the present application has the following beneficial effects:

[0031] 1. The double-bud section sugarcane precision seeding device can precisely seed sugarcane seeds, meeting the requirements of fine agriculture.

[0032] 2. By arranging the second feeding channel, the posture of the sugarcane section can be preliminarily adjusted, so as to facilitate subsequent conveying and final "shaping", because the width of the second feeding channel is smaller than the length of the sugarcane section, and the length direction of the second feeding channel is the same as the conveying direction of the middle conveying belt.

[0033] 3. By arranging the inclined seed conveying plate in the seed box, the posture of the sugarcane section is adjusted to a uniform posture, so as to facilitate subsequent accurate hooking and ensure precise seeding. BRIEF DESCRIPTION OF DRAWINGS

[0041] In order to enable those skilled in the art to better understand the technical solutions of the present application, the present application will be further described below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present application are not limited thereto.

[0042] Referring to Figures 1-3 The double-bud section sugarcane precision seeding device of the present embodiment comprises a vibration feeding mechanism, an intermediate conveying mechanism and a seed arranging mechanism. The vibration feeding mechanism comprises a feeding hopper 1 and a vibration machine 2. The feeding hopper 1 is connected with the vibration machine 2. The feeding hopper 1 is provided with a first feeding channel 3 gradually narrowing at the upper part and a second feeding channel 4 at the lower part. The width of the second feeding channel 4 is smaller than the length of the sugarcane section.

[0043] Further, the first feeding channel 3 is provided with two downward guiding bottom surfaces 5 arranged obliquely. The two downward guiding bottom surfaces 5 are located at different heights. In this way, the two downward guiding bottom surfaces 5 at different heights can prevent the sugarcane section from crossing the outlet of the first feeding channel 3, effectively avoiding the situation of blocking the channel.

[0044] Referring to Figures 1-3 The second feeding channel 4 is provided with a partition plate 6. The partition plate 6 divides the second feeding channel 4 into two falling spaces in the width direction. In this way, when the sugarcane section enters the second feeding channel 4, the initial position adjustment is completed. When the sugarcane section contacts the partition plate 6, it is divided into one of the falling spaces by the partition plate 6, further constraining the posture of the sugarcane section, and again adjusting the position, so as to obtain a relatively uniform posture for the intermediate conveying belt 8 to convey.

[0045] Further, the height of the partition plate 6 is smaller than the height of the downward guiding bottom surface 5 with smaller height, which can effectively avoid the three-point force of the roller and block the channel.

[0046] Referring to Figures 1-3The second feeding channel 4 is provided with a baffle 7 at the end close to the seed metering mechanism; the baffle 7 is inclined forward from bottom to top along the conveying direction of the intermediate conveying belt 8.

[0047] Referring to Figures 3-4 The intermediate conveying mechanism comprises an intermediate conveying belt 8 and a conveying driving mechanism; the intermediate conveying belt 8 is located below the second feeding channel 4, and the conveying direction of the intermediate conveying belt 8 is parallel to the length direction of the second feeding channel 4.

[0048] Further, the intermediate conveying mechanism comprises a limiting plate 9 arranged on both sides of the intermediate conveying belt 8.

[0049] Specifically, the conveying driving mechanism adopts the structure of the prior art.

[0050] Referring to Figures 5-8 The seed metering mechanism comprises a seed metering box 10, a seed metering supporting plate 11, a seed metering conveying belt 12 and a seed metering driving mechanism arranged in the seed metering box 10; the seed metering supporting plate 11 is located below the end of the intermediate conveying belt 8, and is arranged obliquely on one side of the seed metering conveying belt 12, with the lower end extending toward the seed metering conveying belt 12; a plurality of hooks 13 are arranged on the seed metering conveying belt 12 along the length direction of the seed metering conveying belt 12; the seed metering driving mechanism comprises at least two seed metering conveying rollers 14; the seed metering conveying belt 12 is arranged between the seed metering conveying rollers 14; the axes of the seed metering conveying rollers 14 are parallel to the conveying direction of the intermediate conveying belt 8.

[0051] Referring to Figures 5-8 The seed metering mechanism further comprises a feeding roller 15 and a feeding driving mechanism; the feeding roller 15 is arranged between the lower end of the seed metering supporting plate 11 and the seed metering conveying belt 12, and the axis of the feeding roller 15 is parallel to the axes of the seed metering conveying rollers 14. Through the above structure, when the sugarcane segments fall on the seed metering supporting plate 11, they are automatically rolled to one side of the seed metering conveying rollers 14; the seed metering conveying rollers 14 are driven to rotate by the feeding driving mechanism, and the sugarcane segments are rolled to the hooks 13 of the seed metering conveying belt 12 on the other side by the seed metering conveying rollers 14; in this process, the sugarcane segments can be sent to the hooks 13 of the seed metering conveying belt 12 one by one and in place, and more importantly, the rolling seed metering conveying rollers 14 adjust the posture of the sugarcane segments in a dynamic manner, finally ensuring that the sugarcane segments are transferred to the hooks 13 of the seed metering conveying belt 12 in the correct posture, and ensuring normal seed metering work.

[0052] Further, the height difference between the feeding roller 15 and the surface of the seed plate 11 in the direction perpendicular to the surface of the seed plate 11 is equal to the radius of the feeding roller 15. When the sugarcane segments slide down from the seed plate 11, the sugarcane segments collide with the feeding roller 15 due to the height difference, and then are righted and conveyed in parallel to the hook plate 13 of the seed conveyor 12.

[0053] Further, the feeding driving mechanism is composed of a seed driving mechanism. Specifically, the seed driving mechanism adopts the structure of the prior art.

[0054] Referring to Figures 5-8 , both sides of the seed plate 11 are provided with leakage openings 16, and the arrangement direction of the two leakage openings 16 is parallel to the axis of the feeding roller 15. Both ends of the feeding roller 15 are provided with arc-shaped baffles 17, and the curvature of the arc-shaped baffles 17 is greater than the curvature of the feeding roller 15. Through the above structure, the leakage openings 16 can automatically discharge the sugarcane segments in disorder, and the greater curvature of the arc-shaped baffles 17 can prevent the sugarcane segments to be entered into the hook plate 13 of the seed conveyor 12 from being affected by the two arc-shaped baffles 17.

[0055] Referring to Figure 8 , a weighing sensor 18 is arranged below the seed plate 11, so as to realize real-time counting of the amount of sugarcane segments in the seed box 10, thereby preventing the seed box 10 from being overfilled with sugarcane segments.

[0056] Referring to Figures 1-8 , the double-bud segment sugarcane precision seeding method of the embodiment comprises the following steps:

[0057] The sugarcane segments are put into the feeding hopper 1, and at this time, the sugarcane segments are located in the first feeding channel 3. The feeding hopper 1 is driven to vibrate by the vibration machine 2, so as to adjust the posture of the sugarcane segments when they move downward.

[0058] The sugarcane segments are transferred to the second feeding channel 4 through the first feeding channel 3 which gradually narrows. Since the width of the second feeding channel 4 is smaller than the length of the sugarcane segments, and the length direction of the second feeding channel 4 is parallel to the conveying direction of the intermediate conveyor 8, the posture of the sugarcane segments has been preliminarily adjusted and is generally parallel to the conveying direction of the intermediate conveyor 8.

[0059] The sugarcane segments fall downward to the intermediate conveyor 8 below, and the intermediate conveyor 8 conveys the sugarcane segments to the direction of the seed box 10. The sugarcane segments enter the seed box 10 through the seed inlet 10-1 by means of a parabolic motion, and fall onto the inclined seed plate 11. The sugarcane segments are guided by the seed plate 11 to the direction of the seed conveyor 12, so as to roll in the direction of the seed conveyor 12, and then the posture of the sugarcane segments is adjusted to a uniform posture, so as to be accurately hooked subsequently.

[0060] The seed conveying belt 12 is driven to move by the seed conveying drum 14 of the seed driving mechanism, so that the hook plate 13 moves from bottom to top, thereby sequentially hooking the sugarcane segments one by one, and then sequentially sending the sugarcane segments out through the seed outlet 10-2 of the seed box 10.

[0061] The above is the preferred embodiment of the present application, but the embodiments of the present application are not limited by the above, and any changes, modifications, substitutions, combinations, simplifications made without departing from the spirit and principles of the present application should be equivalent replacement methods, and are all included in the protection scope of the present application.
