Description

Technical Field

[0001] This invention belongs to the field of sugarcane planting machine technology, and particularly relates to a conveying device for sugarcane segments and a sugarcane planting machine thereof. Background Technology

[0002] Sugarcane can be eaten as fruit, juiced for beverages, and its stalks can be used medicinally. Furthermore, sugarcane is a primary raw material for sugar production, and sugar is an essential food for humankind, with wide applications in industry, defense, and medicine. However, the labor costs of sugarcane cultivation have increased dramatically, and manual planting easily leads to uneven sowing. Uneven sowing results in some areas of dense growth while others are sparse, or even broken rows, wasting land resources and affecting production efficiency. Therefore, a sugarcane segment conveying device and a sugarcane planting machine are needed.

[0003] Currently, Chinese Patent CN217389398U discloses a sugarcane segment conveying device and a sugarcane planter containing the same, belonging to the field of planting device technology. The sugarcane segment conveying device includes: a main body with a sugarcane segment conveying cavity inside and a sugarcane segment output port on one side; a placement box installed above the main body, containing a placement cavity for placing sugarcane segments, and a sugarcane segment feeding port at the bottom, the sugarcane segment conveying cavity communicating with the placement cavity through the sugarcane segment feeding port; a rotary drive device installed on the outside of the main body; a sugarcane segment conveying mechanism connected to the rotary drive device; and a sugarcane segment conveying cylinder rotatably installed near the sugarcane segment output port within the sugarcane segment conveying cavity, the sugarcane segment conveying cylinder being connected to the rotary drive device, and having multiple sugarcane segment holding slots spaced circumferentially on the conveying cylinder for placing sugarcane segments. This utility model provides a sugarcane segment conveying device capable of arranging sugarcane segments.

[0004] However, when the above-mentioned device is in use, the sugarcane is moved to the discharge port through the discharge channel. There is no limiting and straightening mechanism. If the top opening of the discharge port is small, the sugarcane is easy to fly over the top of the discharge port. If the top opening of the discharge port is large, the sugarcane transported by the sugarcane section conveyor is easy to be placed horizontally, which has a certain impact on the growth of the sugarcane after planting. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a sugarcane segment conveying device and a sugarcane planting machine. Its advantages include: allowing the sugarcane to fall vertically, thus ensuring the normal growth of the sugarcane.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A conveying device for sugarcane segments, which is installed on a sugarcane planter, includes a frame, a fertilizer box is fixedly connected to the top side of the frame, and a fertilizer inlet penetrating the frame is opened on the bottom outer wall of the fertilizer box.

[0008] The top of the frame has a feeding port flush with the fertilizer inlet. A placement box is fixedly connected to the top of the frame via a support rod. The bottom outer wall of the placement box has a placement opening. An inclined feeding plate is fixedly connected to the top of the frame below the placement opening. An inclined and slidable baffle block is installed in the track of the feeding plate. The side of the baffle block near the placement opening is a downward inclined slope. A double-headed motor is fixedly connected to the outer wall of one end of the feeding plate. The output shaft of the double-headed motor is fixedly connected to a connecting shaft. Cams are fixedly connected to both ends of the surface of the connecting shaft. The cams contact the bottom of the baffle block. The cams can apply force to the bottom of the baffle block, causing the baffle block to move up and down along the feeding plate. When the horizontally placed sugarcane rotates from the placement opening to the feeding plate, it falls vertically into the feeding port after being limited by the baffle block.

[0009] The above technical solution works as follows: During use, sugarcane segments are placed horizontally in the placement box. The sugarcane is stacked within the box. The drive motor is started, and its output shaft rotates, causing the transmission shaft to rotate, which in turn rotates the wheels. The frame can then move forward. After the shovel digs open the soil and the fertilizer from the fertilizer inlet falls into the pre-buried hole, the rotating motor is started. The output shaft of the rotating motor rotates, causing the retaining ring to rotate. This allows the sugarcane in the retaining groove to be rotated through the placement opening onto the conveyor plate, where it passes over the inclined baffle block. After the limit is set, the sugarcane falls vertically. When the sugarcane falls, the dual-head motor is activated. The rotation of the output shaft of the dual-head motor causes the connecting shaft to rotate. At this time, the cam can apply force to the bottom of the baffle block. With the sliding of the limit block in the limit groove, the baffle block can move up and down, which can prevent the sugarcane from getting stuck. After the sugarcane falls into the feed inlet, the rotation of the output shaft of the dual-head motor causes the rolling shaft to rotate. This can prevent the sugarcane from getting blocked in the feed inlet. Therefore, the sugarcane falls vertically, which can achieve the effect of preventing blockage and ensuring the normal growth of the sugarcane.

[0010] The present invention is further configured such that a limiting groove is formed on the inner wall of one end of the conveying plate, a limiting block is slidably connected to the inner wall of the limiting groove, the same limiting spring is fixedly connected between the limiting block and the opposite side of the limiting groove, and the limiting block is fixedly connected to the stop block.

[0011] Through the above technical solution: the setting of the limiting block can slide in the inner wall of the limiting groove, and under the action of the limiting spring, the limiting block can be quickly reset, so as to cause the stop block to move up and down reciprocatingly.

[0012] The invention is further configured such that a rotatable retaining ring is provided inside the placement opening, the outer wall of the retaining ring is provided with a plurality of evenly distributed retaining grooves, the inner wall of the retaining grooves is an arc-shaped structure, and the retaining grooves can wrap around the sugarcane.

[0013] The above technical solution, with its arc-shaped structure, facilitates the wrapping of sugarcane in the slot, and each sugarcane is wrapped individually.

[0014] The present invention is further configured such that a rotating motor is fixedly connected to the outer wall of one end of the placement box, the output shaft of the rotating motor is fixedly connected to a rotating shaft, and the rotating shaft is fixedly connected to a retaining ring.

[0015] Through the above technical solution: the setting of the rotating motor can cause the rotating shaft to rotate when the output shaft rotates. At this time, the retaining ring will rotate. The electronically controlled rotation of the retaining ring can make the sugarcane fall one by one in sequence, so as to accurately fall into the pre-buried opening in the soil.

[0016] The present invention is further configured such that both sides of the bottom inner wall of the placement box are inclined, and the lower end of the bottom inner wall of the placement box faces the placement opening.

[0017] The above technical solution involves an inclined design, which makes the contact surface between the sugarcane and the placement box sloped, facilitating the movement of the sugarcane into the slot.

[0018] The invention is further configured such that a rolling groove extending into the feed inlet is formed on the outer wall of one end of the frame, and a rolling shaft is rotatably connected to the inner wall of the rolling groove via a bearing. The rolling shaft is connected to the other output shaft of the dual-head motor via a belt drive.

[0019] Through the above technical solution: the setting of the dual-head motor can cause the rolling shaft to rotate under the rotation of the output shaft. The rotation of the rolling shaft can apply force to the sugarcane in the feed port, which can facilitate the rapid downward movement of the sugarcane and prevent the sugarcane from getting stuck in the feed port.

[0020] A sugarcane planter has an electric telescopic rod fixedly connected to one side of the bottom of the frame. A shovel is provided at the bottom of the electric telescopic rod, and the shovel, fertilizer inlet, and feed inlet are located on the same straight line.

[0021] Through the above technical solution, the shovel is designed to move under the piston rod of the electric telescopic rod, and can then move into the soil to determine the burial depth of the sugarcane.

[0022] The invention is further configured such that a mounting plate is fixedly connected to the bottom of the piston rod of the electric telescopic rod, the mounting plate is hinged to the top of the shovel by a pin, and an electric hydraulic rod is fixedly connected to one side of the bottom of the mounting plate, the piston rod of the electric hydraulic rod is in contact with the back of the shovel.

[0023] Through the above technical solution: the setting of the electric hydraulic rod can apply force to the back of the shovel blade under the movement of the piston rod. After the back of the shovel blade is subjected to force, the shovel blade can turn over the soil on the front of the shovel blade to facilitate the subsequent burying of fertilizer and sugarcane.

[0024] The invention is further configured such that an electric pneumatic rod is fixedly connected to the other side of the bottom of the frame, an electric slide rail is fixedly connected to the bottom of the piston rod of the electric pneumatic rod, electric sliders are slidably connected to both ends of the inner wall of the electric slide rail, and the two electric sliders move in opposite directions. A bulldozer plate is fixedly connected to the bottom of the electric slider, and the opposite side of the two bulldozer plates has an arc-shaped structure.

[0025] The above technical solution, with its arc-shaped structure, avoids damage to the sugarcane by the bulldozer blade. After the sugarcane is placed in the pre-buried opening, the electric pneumatic rod is activated. The movement of the piston rod allows the bulldozer blade to move down to the appropriate position. Then, the electric slide rail is activated, and the electric slider slides in the inner wall of the electric slide rail, which allows the bulldozer blade to move and the soil to fix the sugarcane.

[0026] The invention is further configured such that a connecting plate is fixedly connected to the bottom corner of the frame, and the two connecting plates on the same side are rotatably connected to the same drive shaft via bearings. Wheels are fixedly connected to both ends of the surface of the drive shaft, and a drive motor is fixedly connected to one end of one of the connecting plates. The output shaft of the drive motor is fixedly connected to the drive shaft, and the two drive shafts are connected by belt drive.

[0027] Through the above technical solution: the wheels can rotate under the rotation of the drive shaft, which can make the frame move. When the drive motor is started, the output shaft of the drive motor rotates, which in turn makes the drive shaft rotate, and at this time the wheels can rotate.

[0028] The beneficial effects of this invention are as follows:

[0029] 1. This conveying device for sugarcane segments, by starting a rotating motor, causes the output shaft of the rotating motor to rotate, which in turn causes the retaining ring to rotate. At this time, the sugarcane in the retaining groove is rotated through the placement port onto the conveying plate. After being limited by the inclined stop block, the sugarcane falls vertically. When the sugarcane falls, the double-headed motor can be started. The output shaft of the double-headed motor rotates, which causes the connecting shaft to rotate. At this time, the cam can apply force to the bottom of the stop block. With the sliding of the limit block in the limit groove, the stop block can move up and down, which can prevent the sugarcane from getting stuck. After the sugarcane falls into the conveying port, the output shaft of the double-headed motor rotates, which can cause the rolling shaft to rotate. This can prevent the sugarcane from getting blocked in the conveying port. Therefore, the sugarcane falls vertically, achieving the effect of preventing blockage and ensuring the normal growth of sugarcane.

[0030] 2. The conveying device for sugarcane segments can rotate the output shaft by rotating the motor, which will cause the retaining ring to rotate. The electrically controlled rotation of the retaining ring can make the sugarcane fall one by one in sequence so that it can fall accurately into the pre-buried opening in the soil.

[0031] 3. This conveying device for sugarcane segments uses a bulldozer blade with an arc-shaped structure to avoid damaging the sugarcane. After the sugarcane is placed in the pre-buried opening, the electric pneumatic rod is activated. At this time, the movement of the piston rod can move the bulldozer blade to a suitable position. Then, the electric slide rail is activated. The electric slider slides in the inner wall of the electric slide rail, which can move the bulldozer blade and fix the sugarcane with soil.

[0044] Reference Figure 1-7 A conveying device for sugarcane segments and a sugarcane planter thereof. The conveying device is installed on the sugarcane planter and includes a frame 1. A fertilizer box 2 is fixedly connected to one side of the top of the frame 1. A fertilizer inlet 3 penetrating the frame 1 is opened on the bottom outer wall of the fertilizer box 2.

[0045] The top of the frame 1 has a feeding port 30 that is flush with the fertilizer inlet 3. The top of the frame 1 is fixedly connected to the placement box 4 by a support rod. The bottom outer wall of the placement box 4 has a placement opening 5. The top of the frame 1 below the placement opening 5 is fixedly connected to an inclined feeding plate 6. An inclined and slidable baffle block 7 is set in the track of the feeding plate 6. The side of the baffle block 7 near the placement opening 5 is a downward inclined slope. A double-headed motor 8 is fixedly connected to the outer wall of one end of the feeding plate 6. The output shaft of the double-headed motor 8 is fixedly connected to a connecting shaft 9. Cams 10 are fixedly connected to both ends of the surface of the connecting shaft 9. The cams 10 are in contact with the bottom of the baffle block 7. The cams 10 can apply force to the bottom of the baffle block 7, so that the baffle block 7 moves up and down along the feeding plate 6. When the horizontally placed sugarcane rotates from the placement opening 5 to the feeding plate 6, it falls vertically into the feeding port 30 after being limited by the baffle block 7.

[0046] It should be noted that in this embodiment, a limiting groove 11 is formed on the inner wall of one end of the conveying plate 6. A limiting block 12 is slidably connected to the inner wall of the limiting groove 11. The same limiting spring 13 is fixedly connected between the limiting block 12 and the opposite side of the limiting groove 11. The limiting block 12 is fixedly connected to the stop block 7. The limiting block 12 can slide in the inner wall of the limiting groove 11. Under the action of the limiting spring 13, the limiting block 12 can be quickly reset, so as to cause the stop block 7 to move up and down reciprocally.

[0047] Furthermore, in this embodiment, a rotatable retaining ring 14 is provided in the placement opening 5. The outer wall of the retaining ring 14 is provided with a plurality of evenly distributed retaining grooves 15. The inner wall of the retaining grooves 15 has an arc-shaped structure, and the retaining grooves 15 can wrap the sugarcane. The arc-shaped retaining grooves 15 can easily wrap the sugarcane, and the wrapped sugarcane is one piece.

[0048] A rotating motor 16 is fixedly connected to the outer wall of one end of the placement box 4. The output shaft of the rotating motor 16 is fixedly connected to a rotating shaft 17. The rotating shaft 17 is fixedly connected to a retaining ring 14. When the output shaft of the rotating motor 16 rotates, the rotating shaft 17 will rotate. At this time, the retaining ring 14 will rotate. The electrically controlled rotation of the retaining ring 14 can make the sugarcane fall one by one in sequence so that it can fall accurately into the pre-buried opening in the soil.

[0049] The bottom inner wall of the placement box 4 is inclined on both sides, and the lower end of the bottom inner wall of the placement box 4 faces the placement opening 5. The inclined bottom inner wall of the placement box 4 makes the contact surface between the sugarcane and the placement box 4 inclined, which facilitates the sugarcane to move into the slot 15.

[0050] A rolling groove 18 extending into the feed inlet 30 is provided on the outer wall of one end of the frame 1. A rolling shaft 19 is rotatably connected to the inner wall of the rolling groove 18 via a bearing. The rolling shaft 19 is connected to the other output shaft of the dual-head motor 8 via a belt drive. The dual-head motor 8 can rotate the rolling shaft 19 by rotating the output shaft. The rotation of the rolling shaft 19 can apply force to the sugarcane in the feed inlet 30, which can facilitate the rapid downward movement of the sugarcane and prevent the sugarcane from getting stuck in the feed inlet 30.

[0051] A sugarcane planting machine has an electric telescopic rod 20 fixedly connected to one side of the bottom of the frame 1. A shovel 21 is provided at the bottom of the electric telescopic rod 20. The shovel 21, fertilizer inlet 3 and feed inlet 30 are located on the same straight line. The shovel 21 can move under the movement of the piston rod of the electric telescopic rod 20. At this time, it can move into the soil to determine the burial depth of the sugarcane.

[0052] It should be noted that, in this embodiment, the bottom of the piston rod of the electric telescopic rod 20 is fixedly connected to the mounting plate 22. The mounting plate 22 is hinged to the top of the shovel 21 by a pin. An electric hydraulic rod 23 is fixedly connected to one side of the bottom of the mounting plate 22. The piston rod of the electric hydraulic rod 23 is in contact with the back of the shovel 21. The electric hydraulic rod 23 can apply force to the back of the shovel 21 under the movement of the piston rod. After the back of the shovel 21 is subjected to force, the shovel 21 can turn over the soil on the front of the shovel 21 to facilitate the subsequent burial of fertilizer and sugarcane.

[0053] Furthermore, in this embodiment, an electric pneumatic rod 24 is fixedly connected to the other side of the bottom of the frame 1. An electric slide rail 25 is fixedly connected to the bottom of the piston rod of the electric pneumatic rod 24. Electric sliders 26 are slidably connected to both ends of the inner wall of the electric slide rail 25, and the two electric sliders 26 move in opposite directions. A bulldozer plate 27 is fixedly connected to the bottom of the electric slider 26, and the opposite side of the two bulldozer plates 27 has an arc-shaped structure. The bulldozer plates 27 with their arc-shaped structure can avoid damaging the sugarcane. After the sugarcane is located in the pre-buried opening, the electric pneumatic rod 24 is activated. At this time, the movement of the piston rod can cause the bulldozer plate 27 to move down to a suitable position. Then, the electric slide rail 25 is activated, and the electric sliders 26 slide in the inner wall of the electric slide rail 25, which can cause the bulldozer plate 27 to move, so that the soil can fix the sugarcane.

[0054] A connecting plate is fixedly connected to the bottom corner of the frame 1. The two connecting plates on the same side are rotatably connected to the same drive shaft 28 through bearings. Wheels 29 are fixedly connected to both ends of the surface of the drive shaft 28. A drive motor is fixedly connected to one end of one of the connecting plates. The output shaft of the drive motor is fixedly connected to the drive shaft 28. The two drive shafts 28 are connected by a belt drive. The wheels 29 can rotate under the rotation of the drive shaft 28, which can make the frame 1 move. When the drive motor is started, the output shaft of the drive motor rotates, which can make the drive shaft 28 rotate. At this time, the wheels 29 can rotate.

[0055] Working principle: During use, sugarcane planting sections are placed horizontally in the placement box 4. The sugarcane is then stacked within the box. The drive motor is started, and its output shaft rotates, causing the transmission shaft 28 to rotate, which in turn rotates the wheels 29. At this point, the frame 1 can move forward. After the shovel 21 digs open the soil and the fertilizer in the fertilizer inlet 3 falls into the pre-buried hole, the rotating motor 16 is started. The output shaft of the rotating motor 16 rotates, causing the rotating shaft 17 to rotate. The rotation of the rotating shaft 17 causes the retaining ring 14 to rotate, allowing the sugarcane in the slot 15 to be rotated through the placement port 5 onto the conveying plate 6, where it passes the inclined baffle block. After the limit is set, the sugarcane falls vertically. When the sugarcane falls, the double-headed motor 8 is activated. The output shaft of the double-headed motor 8 rotates, which causes the connecting shaft 9 to rotate. At this time, the cam 10 applies force to the bottom of the baffle block 7. With the sliding of the limit block 12 in the limit groove 11, the baffle block 7 moves up and down, which can prevent the sugarcane from getting stuck. After the sugarcane falls into the feed inlet 30, the output shaft of the double-headed motor 8 rotates, which causes the rolling shaft 19 to rotate. This can prevent the sugarcane from getting blocked in the feed inlet 30. Therefore, the sugarcane falls vertically, which can achieve the effect of preventing blockage and ensuring the normal growth of the sugarcane.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
