Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a rice transplanter. Background Art

[0002] Rice planting requires cultivated rice seedlings to be planted in large rice fields by rice transplanters. During the planting process, the row spacing and plant spacing need to be considered. At present, the mainstream rice transplanters on the market have improved their efficiency compared to manual labor. They can easily handle regular rice fields, but they cannot efficiently transplant rice seedlings in small or irregular rice fields. At this time, manual transplanting is required, especially when the transplanter reaches the edge of the field. The rice field with the remaining length of the machine itself cannot be transplanted. The machine needs to turn around and re-transplant the remaining fields. Not only will the newly transplanted seedlings be crushed by the machine, but the row spacing will also be misplaced.

[0003] In view of the above technical problems, this application proposes a solution. Summary of the invention

[0004] The technical problem to be solved by the present invention is: to overcome the shortcomings of the prior art and provide a rice transplanter.

When the fixed frame 303 is folded, the fixed limit 3032 is separated from the swing frame 308, and the spring 2 309 is against one side of the swing frame 308, so that the pinion 2 307 is separated from the spline shaft 211, preventing the transplanting mechanism 3 in the folded state from working and damaging the components.

In the present invention, the transplanting mechanism 3 is provided with multiple groups, and the row spacing can be controlled by manual movement. Because the movement is performed before transplanting, manual movement is also reasonable.

[0028] A gearbox 103 is fixedly connected to the base 101, and a power gear 105 is fixedly connected to the extended end of the gearbox 103. The function of the gearbox 103 is to increase, reduce or stop the power provided by the power gear 105 to the outside, so as to control the device more conveniently. The power gear 105 is meshed and connected with the shaft gear 2 123. A power assembly 127 is fixedly connected to the base 101 on one side of the gearbox 103. The power assembly 127 is connected to the gearbox 103 through an axis. Four wheels are arranged at the bottom of the base 101, and the wheels are connected to the power assembly 127 through an axis. A steering wheel 102 is fixedly connected to one side of the power assembly 127. The power assembly 127 here includes an engine to provide power for the entire device.

[0029] A base plate 121 is slidably connected to the base 101 above the telescopic mechanism 2, a swing column 126 is fixedly connected to one side of the base plate 121, a swing shaft 125 is rotatably connected to the base 101 at the bottom of the base plate 121, a reciprocating groove is provided in the middle of the swing shaft 125, the swing column 126 abuts against the middle groove of the swing shaft 125, a sprocket is fixedly connected to one side of the swing shaft 125, and the sprocket on the swing shaft 125 is meshed with the chain 2 114.

[0030] It is worth noting that the transplanting mechanism 3 used at the rear end of the present invention is consistent with the transplanting mechanism 3 used on the telescopic mechanism 2. However, the transplanting mechanism 3 used at the rear end can be replaced with a common transplanting mechanism 3 on the market, which has no effect on the innovative direction of the present invention.

[0031] Those skilled in the art can use the existing technologies they know, such as installing corresponding mechanical limit switches or photoelectric sensors to limit the specified positions of each actuator during the following action process; to achieve automated operation, the present invention can use numerical control technology or PLC to control the action of each actuator.

[0032] Working process: When the present invention is moved to the rice field, the seedling blocks are placed in the seedling plate 401 in the lifting mechanism 4. The machine is started, the power gear 105 on the gearbox 103 rotates, the power gear 105 drives the shaft gear 2 123, the shaft gear 2 123 rotates the shaft gear 1 122, so that the power shaft 1 118 and the power shaft 2 119 rotate forward and reverse respectively, the worm on the power shaft 2 119 meshes with the turbine on the rotating shaft 107 and rotates, the sprocket on one side of the rotating shaft 107 meshes with the chain 2 114, the chain 2 114 meshes with the sprocket on the swing shaft 125, driving the swing shaft 125 to rotate, the swing column 126 on the back of the base plate 121 abuts against the inside of the swing shaft 125, driving the base plate 121 to reciprocate.

[0033] The chain 112 is meshed with the sprockets on both sides of the rotating shaft 3 124 meshed with the power shaft 2 119 at the rear end of the device, and the chain 112 is meshed with the sprocket on the spline shaft 211 to drive the spline shaft 211 to rotate. The pinion 2 307 meshed with the spline shaft 211 rotates, which is transmitted to the chain 6 311 through the chain 5 310, driving the elliptical wheel 305 to rotate. The clamping device 304 against the elliptical wheel 305 is supported by the elliptical wheel 305 on one side and stretched by the spring 3 312 on the other side, and reciprocates to clamp the seedlings on the substrate 1 121 and insert them into the rice field.

[0034] Push the telescopic lever 1041 to one side, the gear set 120 tilts, the lead screw 111 rotates, and the telescopic mechanism 2 moves outward. When the telescopic mechanism 2 is fully pushed out, the telescopic lever 1041 returns to the middle position, and the gear set 120 returns to the center position, that is, it does not contact the power shaft 118, the power shaft 219, and the lead screw 111. The gear 4 212 on one side of the spline shaft 211 in the telescopic mechanism 2 meshes with the gear 3 113 on one side of the rotating shaft 3 124, and the spline shaft 211 rotates. The transplanting mechanism 3 in the telescopic mechanism 2 is originally in a folded state, and the springs 1 302 on both sides of the fixed frame 303 unfold the fixed frame 303, and the fixed limit 3032 is against the swing frame 308. The pinion 2 307 on the swing frame 308 meshes with the spline shaft 211. At this time, the pinion 2 307 drives the elliptical wheel 305 to rotate, thereby causing the clamping device 304 to reciprocate and clamp the seedlings from the base plate 213. At this time, the telescopic mechanism 2 only needs to be partially extended from the machine, so the telescopic operating rod 1041 is pushed. After the telescopic mechanism 2 is extended to a suitable distance, the telescopic operating rod 1041 is returned to its original position, and the gear three 113 is engaged with the gear four 212 at the middle position of the spline shaft 211, so that the spline shaft 211 can still be rotated.

[0035] When the telescopic mechanism 2 moves to one side, the conveyor belt operating lever 1042 is pushed, and the worm in the middle of the second shaft 110 meshes and rotates with the gear set 120, and the gears 108 on both sides of the second shaft 110 rotate accordingly. Because the second shaft 110 can be telescopic in the base 101, when it rotates to one side, the worm in the middle of the second shaft 110 is subjected to radial force, pushing the second shaft 110 to one side, and the gear 108 on the other side does not contact with the gear 2 109. The gear 2 109 on the contacting side is meshed and connected with the chain 3 205 in the telescopic mechanism 2, driving the universal shaft 208 to rotate, and then driving the fourth shaft 209. The fourth shaft 209 is provided with a sprocket, and the sprocket is meshed and connected with the chain 4 214. The chain 4 214 is meshed and connected with the sprocket in the conveyor belt 204, so that the conveyor belt 204 rotates. The seedling blocks are put in from one end of the conveyor belt 204 to fill the entire substrate 213 in sequence. It is worth noting that the seedling blocks used in the substrate 213 are smaller than the seedling blocks in the substrate 1 121, in order to facilitate the clamping of the transplanting mechanism in the telescopic mechanism 2.

[0036] When it is necessary to put seedlings onto base plate 121 or base plate 213, it is only necessary to push the lifting joystick 1043. One side of the gear group 120 associated with the lifting joystick 1043 contacts with power shaft 118 or power shaft 2 119, and the other side contacts with lead screw 2 116, driving the slide 117 to the left or right, and the support rod 402 connected to the slide 117 will drive the seedling plate 401 to rise or fall. When it moves to the position of base plate 121 or base plate 2 213 where seedlings need to be put, push the lifting joystick 1043 to the middle position, the gear group 120 side will not contact with power shaft 118 and power shaft 2 119, the seedling plate 401 will stop, and the seedling putting work can be carried out. Workers can complete the seedling putting work without bending over, saving physical energy.

[0037] After the work is completed, the telescopic operating rod 1041 and the lifting operating rod 1043 are pushed to return the device to its original position, and the start and stop of the device can be controlled by controlling the gearbox 103.

[0038] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
