Description
Technical Field
[0001] This utility model belongs to the field of sugarcane planting technology, specifically relating to a continuous seeding device for a sugarcane planter. Background Technology
[0002] Sugarcane is a plant belonging to the genus *Saccharum* of the Poaceae family. It originated in tropical and subtropical regions and is a major economic crop in tropical sugar-producing countries worldwide. When planting sugarcane, a seed metering device is needed to plant the sugarcane.
[0003] Chinese patent application number 202023427308.8 discloses a sugarcane seed stalk arranging device for a pre-cut sugarcane planting machine. It is equipped with an inclined frame plate that is lower in the front and higher in the back. A seed storage bin is provided on the top surface of the inclined frame plate. A corrugated sugarcane pusher plate that slides back and forth is provided on the bottom of the seed storage bin. The sugarcane pusher plate pushes the sugarcane stalks forward from the discharge port of the seed storage bin. The area on the top surface of the inclined frame plate in front of the discharge port of the seed storage bin is the seed placement area. A limiting strip is suspended in the seed placement area. A top sugarcane outlet is left between the front end of the limiting strip and the front edge of the seed placement area. A sugarcane stalk arranging pusher plate that slides up and down is provided below the top sugarcane outlet. The sugarcane stalk arranging pusher plate pushes the foremost sugarcane stalks out one by one from the top sugarcane outlet for arranging. Compared to other sugarcane planter seed metering devices, this device can reduce the number of operators, lower labor intensity, and significantly reduce the production cost of sugarcane planting. At the same time, it can ensure that the seed metering process is not affected by human intervention, changing the current situation where the operating efficiency and quality of sugarcane planters are overly dependent on manual labor.
[0004] The aforementioned patent uses a limiting pressure strip to elastically press the sugarcane stalk, keeping the sugarcane stalk moving forward continuously in a single layer and preventing the sugarcane stalk from stacking up. In use, the height and position of the limiting pressure strip can be adjusted according to the needs of use. However, it is inconvenient to adjust in use, requiring the use of external tools, and it is difficult to keep the positions of multiple limiting compression adjustments the same. Furthermore, in use, if the limiting pressure strip is deformed or damaged after a long period of use, it is not convenient to disassemble and replace it. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1
[0023] Please see Figure 1-5 The present invention provides the following technical solution: a continuous seeding device for a sugarcane planter, comprising a seeding device body 1, a seed storage bin assembly 2 fixedly connected to one end of the seeding device body 1, a sugarcane pushing plate assembly 3 disposed inside the seed storage bin assembly 2, a sugarcane top assembly 4 fixedly connected to the other end of the seeding device body 1, a sugarcane guide trough 5 fixedly connected to one side of the seeding device body 1, a support frame 6 fixedly connected to the middle inside the seeding device body 1, limit pressure strips 7 evenly disposed below the support frame 6, an adjustment assembly 8 fixedly connected to the middle of the support frame 6, and a connecting assembly 9 fixedly connected below the adjustment assembly 8.
[0024] Specifically, the adjustment assembly 8 includes an adjustment seat 81, an adjustment trapezoidal screw 82, an anti-slip handle 83, an adjustment plate 84, a connecting plate 85, and a positioning assembly 86. The adjustment seat 81 is fixedly connected to the middle of the support frame 6. The adjustment trapezoidal screw 82 is rotatably connected to the inside of the adjustment seat 81 through a bearing. One end of the adjustment trapezoidal screw 82 passes through the adjustment seat 81 and is fixedly connected to the anti-slip handle 83. The adjustment plate 84 is threadedly connected to the surface of the adjustment trapezoidal screw 82. The adjustment plate 84 and the adjustment seat 81 are in close sliding connection. The connecting plate 85 is fixedly connected to the lower part of the adjustment plate 84. The positioning assembly 86 is provided at the rotating rod of the anti-slip handle 83.
[0025] By adopting the above technical solution, rotating the anti-slip handle 83 will cause the adjusting trapezoidal screw 82 to rotate, which in turn will cause the adjusting plate 84 to move, which in turn will cause the connecting plate 85 to move, thereby causing the limiting pressure strip 7 to move for position adjustment. The connecting plate 85 facilitates the adjustment of each limiting pressure strip 7 to maintain the same degree of adjustment.
[0026] Specifically, the positioning component 86 includes a gear 861, a support 862, a positioning screw 863, a toothed block 864, a rotating block 865, and a guide slide rod 866. The gear 861 is fixedly connected to the rotating rod of the anti-slip handle 83. The support 862 is fixedly connected to one end of the upper part of the adjusting seat 81. The positioning screw 863 is threadedly connected to the middle of the support 862. The toothed block 864 is rotatably connected to one end of the positioning screw 863. The rotating block 865 is fixedly connected to the other end of the positioning screw 863. The toothed block 864 and the gear 861 are meshed. The guide slide rod 866 is fixedly connected to the upper part of one side of the toothed block 864. The guide slide rod 866 and the support 862 are in close sliding connection.
[0027] By adopting the above technical solution, after adjustment, rotating the rotating block 865 will drive the toothed block 864 to move under the action of the guide slide rod 866, so that the toothed block 864 moves and meshes with the gear 861, thereby positioning the anti-slip throttle 83.
[0028] Specifically, the end of the adjusting trapezoidal lead screw 82 located inside the adjusting plate 84 is fixedly connected to a limit block 87.
[0029] By adopting the above technical solution, the limiting block 87 can easily limit the movement range of the adjusting plate 84.
[0030] In this embodiment, during use: rotating the anti-slip handle 83 causes the adjusting trapezoidal screw 82 to rotate, which in turn moves the adjusting plate 84. The moving adjusting plate 84 then moves the connecting plate 85, thereby moving the limiting pressure strip 7 to adjust its position. The connecting plate 85 facilitates the adjustment of each limiting pressure strip 7, ensuring the same degree of adjustment. After adjustment, rotating the rotating block 865, under the action of the guide slide rod 866, moves the toothed block 864, causing it to engage with the gear 861, thus positioning the anti-slip handle 83. This allows for convenient adjustment of the position of the limiting pressure strip 7 during use, improving ease of use.
[0031] Example 2
[0032] The difference between this embodiment and embodiment 1 is that, specifically, the connecting component 9 includes a connecting seat 91, a square insert 92, a fixing rod 93, a fixing slider 94, and a fixing spring 95. The connecting seat 91 is fixedly connected to the lower part of the connecting plate 85, the square insert 92 is tightly inserted into the lower part of the connecting seat 91, the lower part of the square insert 92 is fixedly connected to the limiting pressure strip 7, the fixing rod 93 is tightly inserted into one side of the square insert 92, the fixing rod 93 and the connecting seat 91 are in close sliding connection, the fixing slider 94 is fixedly connected to the upper part of the fixing rod 93, the fixing slider 94 and the connecting seat 91 are in close sliding connection, and the fixing spring 95 is fixedly connected to one side of the fixing slider 94.
[0033] By adopting the above technical solution, when it is necessary to replace the limiting pressure strip 7, by pulling the fixing rod 93, the fixing rod 93 drives the fixing slider 94 to move and compress the fixing spring 95, so that the fixing rod 93 disengages from the fixing hole on one side of the square insert 92, thereby separating the square insert 92 from the connecting seat 91, and replacing the new limiting pressure strip 7. After obtaining the new limiting pressure strip 7, insert the square insert 92 of the new limiting pressure strip 7 into the connecting seat 91, release the fixing rod 93, and the fixing spring 95 drives the fixing rod 93 to insert into the square insert 92 to complete the fixing.
[0034] Specifically, a limiting seat 96 is fixedly connected to one side of the connecting seat 91, and an L-shaped limiting rod 97 is inserted into the middle of the limiting seat 96. One end of the L-shaped limiting rod 97 passes through the fixing rod 93 and is fixedly connected to a bendable limiting steel wire 98. The L-shaped limiting rod 97 and the fixing rod 93 are slidably connected.
[0035] By adopting the above technical solution, after installation, the L-shaped limiting rod 97 is inserted into the limiting seat 96, with the lower end passing through the fixing rod 93. Then, the flexible limiting steel wire 98 is bent to fix the L-shaped limiting rod 97, thereby fixing the fixing rod 93 through the L-shaped limiting rod 97 and improving the stability of the fixing rod 93.
[0036] In this embodiment, when the limiting pressure strip 7 needs to be replaced, the fixing rod 93 is pulled, which moves the fixing slider 94 to compress the fixing spring 95, causing the fixing rod 93 to disengage from the fixing hole on one side of the square insert 92. This allows the square insert 92 to separate from the connecting seat 91, thus replacing the new limiting pressure strip 7. After obtaining the new limiting pressure strip 7, the square insert 92 of the new limiting pressure strip 7 is inserted into the connecting seat 91. The fixing rod 93 is then released, and the fixing spring 95 moves the fixing rod 93 into the square insert 92, completing the fixation. After installation, the L-shaped limiting rod 97 is inserted into the limiting seat 96, with its lower end passing through the fixing rod 93. Then, the bendable limiting wire 98 is bent to fix the L-shaped limiting rod 97, thereby fixing the fixing rod 93 and improving its stability. This allows the device to easily disassemble and replace the limiting pressure strip 7 during use.
[0037] The structure and operating principle of the seed metering device body 1, seed storage bin assembly 2, sugarcane pushing plate assembly 3, sugarcane top assembly 4, sugarcane guide trough 5, support frame 6, and limiting pressure strip 7 in this utility model have been disclosed in a sugarcane seed stalk metering device for a pre-cut sugarcane planting machine disclosed in Chinese Patent Application No. 202023427308.8. Its working principle is as follows: sugarcane seed stalks are horizontally placed into the seed storage bin. The first crank-connecting rod mechanism drives the pushing plate at the bottom of the bin to slide back and forth. Due to the forward-tilting design of the seed storage bin, the corrugated pushing plate, sliding back and forth, can disturb the sugarcane seed stalks in the seed storage bin, causing them to continuously gather towards the discharge port. Under the enhanced guidance of the triangular guide strip or the sugarcane-disturbing roller, the sugarcane seed stalks are pushed out of the discharge port of the seed storage bin one by one with the reciprocating push of the pushing plate. Limiting pressure strip 7 is provided in the seed distribution area to support the sugarcane seed stalks. The stems are elastically pressed to keep the sugarcane stalks moving forward in a single layer, preventing them from piling up. After the foremost sugarcane stalk is pushed to the front edge of the planting area, the sugarcane stalk is pushed upward from the top sugarcane outlet by the sugarcane pusher plate that slides back and forth. The back-and-forth sliding movement of the pusher plate matches the up-and-down sliding movement of the sugarcane pusher plate. When the pusher plate slides forward and pushes the foremost sugarcane stalk into place, the sugarcane pusher plate retracts to below the inclined frame plate. When the pusher plate slides backward, the sugarcane pusher plate extends to push the sugarcane, thus discharging the sugarcane stalks that have moved forward into place one by one. The sugarcane stalks discharged from the top sugarcane outlet roll forward along the slope of the inclined frame plate, cross the front edge of the planting area, and fall into the guide trough 5. After encountering the reversing bar, the sugarcane stalks fall longitudinally from the lower end of the guide trough 5 into the corresponding longitudinal planting ditch for planting.
[0038] The working principle and usage process of this utility model are as follows: This utility model is used for sugarcane planting, for continuous sowing of sugarcane seed stalks. In use, the sugarcane seed stalks are horizontally placed into the seed storage bin assembly 2. The sugarcane pusher assembly 3 pushes the sugarcane seed stalks to the limiting pressure strip 7. The limiting pressure strip 7 elastically presses against the sugarcane seed stalks, ensuring a single-layer continuous forward movement and preventing the sugarcane seed stalks from piling up. Finally, the sugarcane pushing assembly 4 delivers the sugarcane seed stalks to the guide trough 5, where they fall into the corresponding longitudinal planting furrow for sowing. During use, the limiting pressure strip 8 can be adjusted to suit different needs. The position adjustment of the limiting pressure strip 7 is achieved through the connecting component 9, allowing for quick disassembly and replacement of the limiting pressure strip 7. When using the adjusting component 8, rotating the anti-slip handle 83 causes the adjusting trapezoidal screw 82 to rotate, which in turn moves the adjusting plate 84. This movement of the adjusting plate 84 then moves the connecting plate 85, thereby adjusting the position of the limiting pressure strip 7. The connecting plate 85 facilitates the adjustment of each limiting pressure strip 7, ensuring consistent adjustment. After adjustment, rotating the rotating block 865 moves the guide slide rod 866... Under its action, the toothed block 864 moves, engaging with the gear 861 to position the anti-slip handle 83. This allows for convenient adjustment of the position of the limiting strip 7 during use, improving ease of use. When the connecting assembly 9 needs to replace the limiting strip 7, pulling the fixing rod 93 moves the fixing slider 94, compressing the fixing spring 95. This disengages the fixing rod 93 from the fixing hole on one side of the square insert 92, allowing the square insert 92 to separate from the connecting seat 91 and replace the new limiting strip. 7. Next, obtain a new limiting pressure strip 7, insert the square insert 92 of the new limiting pressure strip 7 into the connecting seat 91, loosen the fixing rod 93, and the fixing spring 95 drives the fixing rod 93 to insert into the square insert 92 to complete the fixing. After installation, insert the L-shaped limiting rod 97 into the limiting seat 96, with the lower end passing through the fixing rod 93, and then bend the bendable limiting steel wire 98 to fix the L-shaped limiting rod 97. Thus, the fixing rod 93 is fixed by the L-shaped limiting rod 97, improving the stability of the fixing rod 93. This allows the limiting pressure strip 7 to be easily disassembled and replaced during use.
