AI Technical Summary
When riding-type high-speed rice transplanters pass through paddy fields with hard mud layers formed by tree root holes, the wheels are prone to getting stuck in the holes, causing the machine to malfunction.
The device employs a lifting mechanism, which includes an upper support body, a lower support body, and an air cushion device. By inflating the air cushion, the lower support body is lowered and placed on the mud surface, raising the walking unit. Combined with guide wheels and a rope pulling device, the walking unit is able to slide and detach. Furthermore, the gripping device increases the resistance between the lower support body and the mud layer.
When the rice transplanter gets stuck, the airbags inflate and lift the walking part, reducing its contact with the mud surface. The pull rope and gripping device help the walking part quickly get out of the pit and automatically reset, ensuring the normal operation of the rice transplanter.

Abstract
Description
Technical Field
[0001] This invention relates to the field of rice transplanter technology, and in particular to a riding-type high-speed rice transplanter and its usage method. Background Technology
[0002] A high-speed rice transplanter is a machine used for transplanting rice seedlings in paddy fields and is widely used in modern agriculture.
[0003] However, some paddy fields were transformed from forest farms, leaving deep tree root pits in certain locations. These pits also create hard mud layers in these fields. After a soft mud layer covers the hard mud layer, the location of the pits is not visible on the surface. When a ride-on high-speed rice transplanter passes through these pits, its wheels will sink into them, causing the entire machine to become stuck in the mud and unable to get out, thus affecting the normal use of the rice transplanter. Summary of the Invention
[0004] This invention addresses the shortcomings of existing technologies by providing a ride-on high-speed rice transplanter and its usage method.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a riding-type high-speed rice transplanter, comprising a walking unit and a lifting device, the lifting device comprising an upper support body, a lower support body, and an air cushion device, a guide device being provided on the walking unit, the upper support body being guided and slidably mounted on the guide device of the walking unit, the upper support body and the lower support body being connected by the air cushion device, an inflation / extraction device being provided on the walking unit, the inflation / extraction device being connected to the air cushion device through a pipe, the inflation / extraction device starting to inflate, the lower support body descending to support the mud surface, causing the walking unit to be raised a certain height relative to the mud surface, the walking wheels on the walking unit rotating, the walking wheels acting on the mud surface, the lifting device remaining stationary, the walking unit moving forward relative to the mud surface, leaving the muddy position.
[0006] Its beneficial effect is that when the rice transplanter is stuck in the mud, the airbag can be inflated to raise the walking part to a certain height, reducing its contact with the mud surface. At the same time, the walking part can slide on the lifting device, thereby helping the walking part to leave the stuck position.
[0007] In the above scheme, preferably, when the upper support is installed on the walking part, the front end position is higher than the rear end position, and it is in an inclined state relative to the horizontal plane.
[0008] In the above scheme, preferably, the walking unit includes a main frame, a rear wheel assembly, and a pulling device. Guide wheels are provided on both the main frame and the rear wheel assembly. Guide grooves are provided on both sides of the upper end face of the upper support. The guide wheels are guided and slidably disposed in the guide grooves. The pulling device includes a spool and a first pull rope. The spool is rotatably disposed on the walking unit. One end of the first pull rope is connected to the front end of the upper support and the other end is connected to the spool. The rotation of the spool can pull the upper support to move backward.
[0009] In the above scheme, preferably, the rear wheel device includes a rear wheel axle and a connecting plate. A first gear is provided on the rear wheel axle, and the spool is rotatably mounted on the connecting plate. A second gear is provided on the spool. The connecting plate is provided with a telescopic device, and a third gear is rotatably mounted on the telescopic device. When the telescopic device extends downward, the third gear can simultaneously mesh with the first gear and the second gear, thereby causing the rear wheel to rotate and simultaneously driving the spool to rotate.
[0010] In the above scheme, preferably, a first elastic element is provided in the guide groove, with its two ends respectively abutting against the front end surface of the guide groove and the main frame.
[0011] Its beneficial effect is that after the walking part is lifted, it can be pulled away from the trapped position by pulling ropes, so that the walking part can quickly get out of the trap.
[0012] In the above-mentioned scheme, preferably, multiple transverse grooves are provided on the bottom surface of the lower support part, and guide rods are provided in the front-to-back direction in the transverse grooves. A ground gripping device is also provided in the transverse grooves. The ground gripping device includes a first connecting plate, a second connecting plate, and a sliding member. One end of the first connecting plate is rotatably disposed at the front end of the transverse groove, and the other end is rotatably connected to one end of the second connecting plate. The other end of the second connecting plate is rotatably connected to the sliding member. The sliding member is slidably disposed on the guide rod. One end of the second pull rope is connected to the front end of the sliding member, and the other end extends forward along the guide rod and extends upward from the front end of the sliding rod to connect to the bottom surface of the upper support part. When the lower support part moves downward, the sliding member is pulled forward by the second pull rope, so that the connection between the first connecting plate and the second connecting plate moves downward.
[0013] In the above scheme, preferably, a limit block is provided at the front end of the transverse groove. After the first connecting rod plate rotates a certain angle, that is, when the air cushion device is fully extended, the first connecting rod plate touches the limit block and can no longer rotate forward. When the lower support body is subjected to a backward force, the first connecting rod plate and the second connecting rod plate no longer move forward.
[0014] Its beneficial effect is that as the lower support extends downward, the gripping device is activated simultaneously, forming a V-shaped protrusion that inserts into the mud layer, increasing the resistance between the lower support and the mud layer.
[0015] In the above scheme, preferably, the telescopic device is an electric telescopic rod. The air cushion device is an annular air cushion. After inflation, the height of the front end is greater than the height of the rear end. When fully extended, the lower support is in a horizontal state. When the air cushion device is fully extended and reaches a certain air pressure value, the telescopic device extends forward.
[0016] In the above scheme, preferably, the second pull rope is an elastic pull rope, and a pressure switch is provided on the upper support body. After the air pumping device pumps air out of the air cushion device, under the action of the second pull rope, the lower support part moves upward and touches the upper support body, pressing against the pressure switch, controlling the telescopic device to retract, and the lifting device returns to its initial state under the action of the first elastic element.
[0017] Its beneficial effect is that after the jacking device is released from the depression, it can automatically reset and be restarted when climbing out of the depression again.
[0018] A method for using a ride-on high-speed rice transplanter:
[0019] S1: After the walking unit sinks, the operator presses the sinking release switch, and the air pumping device starts to inflate, causing the lower support to extend downwards and press against the mud surface, raising the walking unit and reducing the number of parts in contact with the mud surface.
[0020] S2: The walking wheels start to rotate, generating a forward force with the mud surface, causing the walking part to move forward and slide on the upper support part, leaving the stuck position and completing the escape.
[0021] S3: The air pumping device pumps air out, and the lower support rises to reset.
[0022] The beneficial effects of the present invention are as follows: The present invention provides a riding-type high-speed rice transplanter and its method of use. When the rice transplanter is in a state of being stuck, the walking part is raised to a certain height to reduce the contact with the mud surface. The walking part is pulled by a rope to slide on the lifting device, so that the rice transplanter leaves the stuck position. The walking part can quickly get out of the mud. At the same time, after getting out of the mud, it automatically resets and can be reused. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-8 A ride-on high-speed rice transplanter includes a walking unit 1 and a lifting device 2. The walking unit 1 includes a main frame 13, a rear wheel assembly 14, and a pulling device 15. Support plates are symmetrically arranged on the main frame 13 and the rear wheel assembly 14, and each support plate is rotatably equipped with a guide wheel 131. The lifting device 2 includes an upper support body 21, a lower support body 22, an air cushion device 23, and a gripping device 24. Guide grooves 211 are provided at both ends of the upper end face of the upper support body 21. The left and right guide wheels 131 on the walking unit 1 are respectively guided and slidably arranged on the left and right guide grooves 211. Thus, through four-point support, the upper support body 21 is guided and slidably arranged on the four sets of guide wheels 131. On the upper support 21, a first elastic element 212 is provided in the guide groove 211. The two ends of the first elastic element 212 respectively abut against the front end surface of the guide groove 211 and the main frame 13. At the same time, the axis position of the front guide wheel 131 is higher than the axis position of the rear guide wheel 131. Therefore, after the upper support 21 is installed and rotated, there is a certain angle with the horizontal plane. The angle range is 0 degrees to 30 degrees. The air cushion device 23 is an annular air cushion. The upper end of the air cushion device 23 is connected to the upper support 21, and the lower end is connected to the lower support 22. An inflation and deflation device 11 is provided on the main frame 13. The inflation and deflation device 11 is connected to the cushion device 23 through a pipe.
[0032] When the rice transplanter is stuck in the mud, the operator presses the release button, and the inflation and depressurization device 11 begins to inflate the air cushion device 23, causing the lower support plate 22 to extend downwards and press against the mud surface, thereby lifting the rice transplanter upwards. This causes the main frame 13 of the rice transplanter to detach from the mud surface, with only the paddy wheel part in contact with the mud surface. At the same time, after the air cushion device 23 is inflated, the front height is greater than the rear height. When it is fully extended, the lower support part 22 is in a horizontal state. At this time, the paddy wheel of the walking part 1 begins to rotate. When the degree of stuckness is not great, the paddy wheel of the walking part 1 acts on the mud surface, giving the walking part 1 a forward thrust, thereby causing the walking part 1 to move forward relative to the lifting device 2 and leave the stuck position.
[0033] The rear wheel assembly 14 includes a rear wheel axle 141, a connecting plate 142, and a telescopic device 143. A rear wheel is provided on the outer end of the rear wheel axle 141, and the other end of the rear wheel axle 141 extends toward the middle of the walking part 1. A first gear 1411 is provided at the extended position. The pulling device 15 includes a spool 151 and a first pull rope 152. The spool 151 is rotatably mounted on the connecting plate 142, and a second gear 1511 is provided on the spool 151. One end of the first pull rope 152 is connected to the spool 151, and the other end is connected to the front end of the upper support part 21. The first gear 1411 does not contact the second gear 1511. The telescopic device 143 is mounted on the connecting plate 142. The telescopic device 143 is an electric telescopic rod. A third gear 1431 is rotatably mounted on the telescopic device 143. When the telescopic device 143 extends downward, the third gear 1431 can simultaneously mesh with the first gear 1411 and the second gear 1511.
[0034] When the air cushion device 23 is fully extended and the air pressure inside the air cushion device 23 reaches the set value, the central control device controls the inflation and depressurization device 11 to stop inflation and switch to pressure maintenance. At the same time, it controls the telescopic device 143 to extend downward, so that the third gear 1431 meshes with the first gear 1411 and the second gear 1511. At this time, the rice transplanter is controlled to move. When the paddy field wheel contacts the mud surface, the rice transplanter generates a forward thrust. At the same time, the rear wheel axle 141 drives the reel 151 to rotate, winding the first pull rope 152 onto the reel 151. This causes the upper support body 21 to move relative to the walking part 1. At this time, the lower support body 22 presses against the mud surface. The friction between the lower support body 22 and the mud surface is greater than the resistance of the mud surface to the walking part 1. Thus, the lifting device 2 remains stationary, causing the walking part 1 to move forward and pull the walking part 1 away from the stuck position.
[0035] Multiple transverse grooves 221 are sequentially formed on the front and rear positions of the bottom surface of the lower support 22. A guide rod 222 is arranged in the front and rear direction in each transverse groove 221. The gripping device 24 includes a first connecting plate 241, a second connecting plate 242, and a sliding member 243. One end of the first connecting plate 241 is rotatably fixed at the front end of the transverse groove 211. The sliding member 243 is slidably mounted on the guide rod 222. A second elastic member 245 is sleeved on the guide rod 222. The two ends of the second elastic member 245 respectively abut against the sliding member 243 and the front end face of the transverse groove 221. The rear end of the second connecting plate 242 is rotatably mounted on the sliding member 243, and the front end is rotatably connected to one end of the first connecting plate 241. One end of the second pull rope 244 is connected to the front end of the sliding member 243. The other end of the second pull rope 244 extends forward, passes through the front end of the guide rod 222, and extends upward to connect to the lower end face of the upper support 21.
[0036] When the air cushion device 23 begins to inflate, the lower support 22 moves downward, thereby pulling the slider 243 forward via the second pull rope 244. Initially, the angle between the first connecting plate 241 and the second connecting plate 242 is less than 180 degrees. Therefore, when the rear rotation point of the second connecting plate 242 moves forward, the rotation point positions of the second connecting plate 242 and the first connecting plate 241 move downward. A limit block 223 is provided at the front end of the transverse groove 221 to prevent the slider 243 from moving forward. After moving forward a certain distance, the first linkage plate 241 rotates at a certain angle and presses against the limit block 223, thereby stopping the sliding member 243 from moving forward. At this time, the first linkage plate 241 and the second linkage plate 242 form a V-shaped protrusion, and the second pull rope 244 is an elastic pull rope. Therefore, when the support body 22 continues to move downward, the second pull rope 244 is stretched, and the V-shaped protrusion structure is elastically tightened. When the support body 22 presses against the mud surface, the V-shaped protrusion is inserted into the mud surface.
[0037] When the V-shaped protrusion is inserted into the mud, it increases the resistance between the lower support body 22 and the mud. When the first pull rope 152 pulls the walking part 1 forward, the lower support body 22 generates a backward thrust on the mud. At this time, the V-shaped protrusion can no longer move forward and is therefore in a fixed state. This increases the resistance between the lower support body 22 and the mud layer, keeping the lifting device 2 stationary. The first pull rope 152 can pull the walking part 1 forward, causing the walking part 1 to leave the position where it has climbed into the mud.
[0038] After the walking part 1 leaves the crawling position, the wheels stop rotating. The central controller controls the air pumping device 11 to pump air from the air cushion device 23, and the air cushion device 23 begins to retract. At this time, the second pull rope 244 is in an elastically stretched state. Under the action of the second pull rope 244, the lower support plate 22 begins to move upward. At the same time, under the action of the second elastic element 245, the sliding element 243 moves backward, and the V-shaped protrusion opens, its height decreases, and it retracts into the transverse groove 221. When all the air in the air cushion device 23 is pumped out, the lower support plate 22 presses against the pressure switch 213 on the upper support body 21, thereby controlling the telescopic device 143 to retract. The third gear 1431 disengages from the meshing first gear 1411 and second gear 1511, thereby locking the reel 151. Under the action of the first elastic element 212, the upper support body 21 slides forward to return to its initial state.
[0039] Its working principle or usage method is as follows:
[0040] When the rice transplanter is stuck in the mud, the operator presses the release button, and the inflation and depressurization device 11 starts to inflate the air cushion device 23, causing the lower support plate 22 to extend downward and press against the mud surface, thereby lifting the rice transplanter upward. When the air cushion device 23 is fully extended and the air pressure inside the air cushion device 23 reaches the set value, the central control device controls the inflation and depressurization device 11 to stop inflating and switch to pressure maintenance.
[0041] When the air cushion device 23 begins to inflate, the lower support body 22 moves downward, pulling the slider 243 forward via the second pull rope 244. The rear rotation point of the second connecting rod plate 242 moves forward, causing the rotation points of the second connecting rod plate 242 and the first connecting rod plate 241 to move downward. After the slider 243 moves forward a certain distance, the linked first connecting rod plate 241 rotates at a certain angle and presses against the limiting block 223, thus stopping the slider 243 from moving forward. At this time, the first connecting rod plate 241 and the second connecting plate 242 form a V-shaped protrusion. Since the second pull rope 244 is an elastic pull rope, as the support body 22 continues to move downward, the second pull rope 244 is stretched, and the V-shaped protrusion structure is elastically tightened. When the support body 22 presses against the mud surface, the V-shaped protrusion inserts into the mud surface.
[0042] After the V-shaped protrusion is inserted into the mud, the resistance between the lower support body 22 and the mud increases. At this time, the telescopic device 143 extends downward, causing the third gear 1431 to mesh with the first gear 1411 and the second gear 1511 simultaneously. At this time, the paddy wheel of the control unit begins to rotate. When the paddy wheel contacts the mud, it causes the rice transplanter to generate a forward thrust. At the same time, the rear wheel axle 141 drives the reel 151 to rotate, winding the first pull rope 152 onto the reel 151, thereby causing the upper support body 21 and the walking unit 1 to move relative to each other. Meanwhile, the lower support body 22 presses against the mud. When the first pull rope 152 pulls the walking unit 1 forward, the lower support body 22 generates a backward thrust on the mud. At this time, the V-shaped protrusion can no longer move forward and is therefore in a fixed state, which further increases the resistance between the lower support body 22 and the mud layer. The lifting device 2 remains stationary, causing the walking unit 1 to move forward and pull the walking unit 1 away from the crater position.
[0043] After the walking unit 1 leaves the crawling position, the wheels stop rotating. The central controller controls the air pumping device 11 to pump air from the air cushion device 23, causing the air cushion device 23 to begin to retract. At this time, the second pull rope 244 is in an elastically stretched state. Under the action of the second pull rope 244, the lower support plate 22 begins to move upward. At the same time, under the action of the second elastic element 245, the sliding element 243 moves backward, causing the V-shaped protrusion to open, its height to decrease, and it to retract into the transverse groove 221. When all the air in the air cushion device 23 is pumped out, the lower support plate 22 presses against the pressure switch 213 on the upper support body 21, thereby controlling the telescopic device 143 to retract. The third gear 1431 disengages from the meshing first gear 1411 and second gear 1511, thereby locking the reel 151. Under the action of the first elastic element 212, the upper support body 21 slides forward to return to its initial state.
[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
