Abstract
Description
Technical Field
[0001] This utility model relates to the field of sugarcane production technology, specifically to an overhead sugarcane conveying device. Background Technology
[0002] After the sugarcane matures, it needs to go to the workshop for production processes such as washing, cutting, and peeling in order to package and transport the sugarcane for easy sale. When cutting the sugarcane, an overhead sugarcane conveyor is needed to transport the sugarcane to the cutting process at a uniform speed.
[0003] Existing sugarcane conveying devices use a single-direction, two-point clamping method when clamping sugarcane. When only the front end is clamped, the rear end of the sugarcane may swing or slip due to gravity or inertia. This can easily cause the sugarcane to derail, especially during high-speed conveying or sudden stops. At the same time, when the front end is clamped at a single point, all the weight and resistance of the sugarcane are concentrated at the clamp, which can easily lead to wear on the clamp or damage to the sugarcane skin. Summary of the Invention
[0004] The purpose of this invention is to provide an overhead sugarcane conveying device to solve the problem that existing devices, which use front-end clamping, may cause the rear end of the sugarcane to swing or slip due to gravity or inertia.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an overhead sugarcane conveying device, including a guide rail, with sliding grooves on both sides of the guide rail, a power box on the outer surface of the guide rail, a rotating wheel rotatably connected to both sides inside the power box, two pulleys rotatably connected inside the power box, a connecting belt sleeved between the two pulleys, a motor fixedly connected inside the power box, a heat dissipation mesh opening at the bottom of the power box and below the motor, a connecting plate fixedly connected to the front of the power box, a double-headed cylinder fixedly connected to the front of the connecting plate, power plates fixedly connected to the two output shafts of the double-headed cylinder, clamps fixedly connected to the bottom of the two power plates, two sliding grooves opening at the top of the connecting plate extending through the bottom and towards the rear, a screw rotatably connected inside the two sliding grooves, a slider slidably connected inside the two sliding grooves, and clamps fixedly connected to the bottom of the two sliders extending through the sliding grooves.
[0006] Preferably, the rotating wheel is located inside the slide groove and is pressed against the slide groove. The two rotating wheels are respectively connected to two pulleys, and the output shaft of the motor is connected to the bottom of the pulley on one side.
[0007] Preferably, the slider is slidably connected to the sliding groove, and the slider is threadedly connected to the screw, with the threads of the two screws having opposite directions.
[0008] Preferably, the bottom of the pair of clamps at the front and the bottom of the pair of clamps at the rear are on the same horizontal plane, and the inner side of the clamps is connected with an anti-slip pad.
[0009] Preferably, the two screws are connected to each other, and a passive bevel gear is fixedly connected to the outer surface of one screw, an active bevel gear is rotatably connected to the inside of the connecting plate, a connecting shaft is fixedly connected to the front of the active bevel gear, a gear is fixedly connected to one end of the outer surface of the connecting shaft, and a rack is fixedly connected to the rear of the power plate on one side.
[0010] Preferably, the first gear meshes with the first rack, the first rack is slidably connected to the connecting plate, and the passive bevel gear meshes with the active bevel gear.
[0011] Preferably, a gear one is also fixedly connected to the outer surface of the connecting shaft and to the rear of the gear one. A gear two that meshes with the gear one at the rear is rotatably connected inside the connecting plate. A rack two is fixedly connected to the rear of the power plate on the other side, and the rack two meshes with the gear two.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1) By rotating the two screws synchronously, the two chucks at the rear move synchronously, and together with the two chucks at the front, they form a four-point clamping system, which avoids the sugarcane being clamped only by the front end, which may cause the rear end of the sugarcane to swing or slip due to gravity or inertia.
[0014] 2) When the front double-headed cylinder is activated, the rack and pinion drive the gear to rotate. The two screws rotate automatically through the drive bevel gear and the driven bevel gear, thus completing the mechanical linkage of the clamping action. Therefore, the front and rear clamping sections can operate synchronously and at the same speed.
[0015] 3) During the movement of the power plate on the other side, it drives the rack two to slide, which in turn drives the gear two to rotate synchronously, and then drives the gear one to rotate synchronously in the opposite direction, thus providing another rotational force in the same direction to the connecting shaft. Therefore, the connecting shaft can be subjected to two rotational forces, which increases the torque of the connecting shaft. Attached Figure Description

Detailed Implementation
[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] Combination Figure 1 - Figure 4 The top-mounted sugarcane conveying device includes a guide rail 1, with sliding grooves 2 on both sides of the guide rail 1. A power box 3 is installed on the outer surface of the guide rail 1. Rotary wheels 11 are rotatably connected to both sides inside the power box 3. Two pulleys 12 are rotatably connected inside the power box 3. A connecting belt 13 is sleeved between the two pulleys 12. A motor 14 is fixedly connected inside the power box 3. A heat dissipation mesh 15 is opened at the bottom of the power box 3 and at the bottom of the motor 14. A connecting plate 4 is fixedly connected to the front of the power box 3. A double-headed cylinder 8 is fixedly connected to the front of the connecting plate 4. Power plates 9 are fixedly connected to the two output shafts of the double-headed cylinder 8. Clamps 10 are fixedly connected to the bottom of the two power plates 9. Two sliding grooves 5 are opened at the top of the connecting plate 4, extending through the bottom and towards the rear. Screws 6 are rotatably connected inside the two sliding grooves 5. Sliders 7 are slidably connected inside the two sliding grooves 5. Clamps 10 are also fixedly connected to the bottom of the two sliders 7 and extending through the sliding grooves 5.
[0024] In actual operation, the double-headed cylinder 8 is started, and the two output shafts of the double-headed cylinder 8 retract, driving the two power plates 9 to move closer to each other, which in turn drives the two clamps 10 at the front to move closer to one end, thus clamping the front end of the sugarcane. At this time, the motor 14 is started, driving the pulley 12 on one side to rotate, and through the connecting belt 13, driving the pulley 12 on the other side to rotate synchronously, thus driving the two rotating wheels 11 to rotate synchronously, which in turn drives the power box 3 to slide forward along the two sliding grooves 2, thus driving the connecting plate 4 and the double-headed cylinder 8 to move forward synchronously, thus conveying the sugarcane to the cutting process;
[0025] Specifically, since the threads of the two screws 6 are opposite, the two screws 6 are rotated synchronously, which drives the two sliders 7 to slide closer to each other along the inside of the two sliding grooves 5, thus driving the two clamps 10 at the rear to move closer to one end, thereby clamping the rear end of the sugarcane.
[0026] The rotating wheel 11 is located inside the slide groove 2 and is pressed against the slide groove 2. The two rotating wheels 11 are respectively connected to the two pulleys 12, and the output shaft of the motor 14 is connected to the bottom of the pulley 12 on one side.
[0027] The slider 7 is slidably connected to the sliding groove 5, and the slider 7 is threadedly connected to the screw 6, with the threads of the two screws 6 in opposite directions.
[0028] The bottom of the pair of chucks 10 at the front and the pair of chucks 10 at the rear are on the same horizontal plane, and the inner side of the chucks 10 is connected with an anti-slip pad.
[0029] Two screws 6 are connected to each other. A passive bevel gear 16 is fixedly connected to the outer surface of one of the screws 6. An active bevel gear 17 is rotatably connected inside the connecting plate 4. A connecting shaft 18 is fixedly connected to the front of the active bevel gear 17. A gear 19 is fixedly connected to one end of the outer surface of the connecting shaft 18. A rack 21 is fixedly connected to the rear of the power plate 9 on one side.
[0030] Specifically, as the power plate 9 on the front side moves, it drives the rack 21 to slide inside the connecting plate 4, which in turn drives the gear 19 at the front to rotate. This causes the connecting shaft 18 to rotate, and through the meshing passive bevel gear 16 and active bevel gear 17, it drives the two screws 6 to rotate synchronously. This causes the two clamps 10 at the rear to clamp the rear end of the sugarcane.
[0031] Gear 19 meshes with rack 21, rack 21 is slidably connected to connecting plate 4, and driven bevel gear 16 meshes with driving bevel gear 17.
[0032] Gear 19 is also fixedly connected to the outer surface of the connecting shaft 18 and to the rear of gear 19. Gear 20 is rotatably connected to the inside of the connecting plate 4 and meshes with gear 19 at the rear. Rack 22 is fixedly connected to the rear of the power plate 9 on the other side and meshes with gear 20.
[0033] As the power plate 9 on the other side moves, it drives the rack 22 to slide, which in turn drives the gear 20 to rotate synchronously, and then drives the gear 19 to rotate synchronously in the opposite direction, thereby providing another rotational force in the same direction to the connecting shaft 18.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
